Specification

[0001] The present subject matter described herein, relates to a mounting assembly of a steering angle sensor. More particularly, to a mounting assembly of a steering angle sensor on a steering column of vehicle.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Generally, steering angle sensor is mounted over a steering column with the help of a contact coil, in case of in built airbag feature variants or a lighting switch, in case of in built auto light feature variants. The purpose of the contact coil is to help in opening of airbags when the crash happens and the purpose of the lighting switch is to maneuver head lights of the vehicle automatically.
[0004] Technical Problem: In vehicles of low variants, original equipment manufacturers (OEM's) do not provide airbags or automatically maneuvering head lights due to cost factors. As per the norms of the government, the usage of electronic stability control or electronic stability program has been made mandatory in the vehicles for road safety. The steering angle sensor is a component of electronic stability control. Now, the question arises on the location of mounting of the steering angle sensor in the absence of the contact coil or the lighting switch.
[0005] One solution for the above mentioned technical problem disclosed in prior patent application publication CN105835939A is to integrally mount the

steering wheel angle sensor on the steering column. The steering column of the integrated steering wheel angle sensor includes a tube body arranged outside a steering wheel rotation shaft in a sleeving mode, wherein the tube body comprises an upper tube body and a lower tube body, a flange body is arranged at the upper end of the lower tube body, a housing body with an open lower end is arranged at the lower end of the lower tube body, and the lower end face of the housing body is fixedly connected with the flange body through a bolt to form a housing for configuring the steering wheel rotation angle sensor. A first opening portion is formed in one side face of the housing body, a second opening portion is formed in the other side, the opening angle of the first opening portion is not greater than 180 degrees, the first opening portion is used for configuring a detection body of the steering wheel rotation angle sensor, and the second opening portion is used for configuring a limiting rod of the steering wheel rotation angle sensor. Rapid integration of an ESP system can be achieved on the basis that a combination switch, a clock spring, a steering wheel assembly, a steering lock assembly and the like are not changed, the varieties of newly developed parts are decreased, a development period is shortened, and the development costs are reduced.
[0006] Another solution for the above mentioned technical problem disclosed in prior patent application publication CN207374482A is to provide a steering pipe column with an angle speed sensor of a steering wheel, which comprises a steering pipe column body, a multi-angle sensor of a steering wheel, an upper bracket and an output shaft connected with one end of the body, wherein, the multi-angle sensor is arranged on the body. The steering pipe column is characterized in that the sensor is connected with the upper bracket through a fixed bracket. The angle speed sensor of a steering wheel of the steering pipe column is fixedly arranged at the bottom of a steering pipe column assembly through the fixed bracket, therefore, the steering angle of the steering wheel can be well recorded by the angle speed sensor, the errors because of assembly results are decreased, the selection of an electric stabilizing program ESP is convenient,

the development of a new steering pipe column is not required, the commonality is kept, and the development cost is reduced.
[0007] Existing solutions or structures provide information on currently available solutions for mounting the steering angle sensor on the steering column, but each has its own drawbacks and limitations. These known systems do not provide solution to mounting of the steering angle sensor at any location across the steering column.
[0008] Therefore, a simple and in-expensive solution is required for mounting the steering angle sensor at any location across the steering column based on packaging requirement.
OBJECTS OF THE DISCLOSURE
[0009] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed herein below.
[0010] The principal object of the present invention is to mount a steering angle sensor at any location across a steering column.
[0011] Another object of the present invention is to calculate the angular movement of a steering wheel.
[0012] One more object of the present invention is to provide an assembly for mounting a steering angle sensor.
[0013] Still another object of the present invention is to calculate the angular movement of a steering wheel with relative rotation of the inner components of a steering angle sensor.
[0014] These and other objects and advantages will become more apparent when reference is made to the following description and accompanying drawings.

10 [0031] As shown in figure 1(a), 1(b), 1(c) and 1(d), there is provided a
mounting assembly 400 of a steering angle sensor 300 on a steering column 200 comprising a housing 402 and a rotor plate 404.
[0032] Referring to figure 1(d), the housing 402 is provided with integrally
formed flanges 402(a) at opposite sides of its free end. The integrally formed
15 flanges 402(a) of the housing 402 are provided with holes 402(a1).
[0033] Referring to figure 1(a) and 1(d), the steering column 200 comprises
an outer jacket 202 and an inner shaft 204. The inner shaft 204 is coupled to a
steering wheel 100 at one end. The outer jacket 202 includes an upper portion
202(a) and a lower portion 202(b). The rotor plate 404 is press fitted onto the
20 inner shaft 204 of the steering column 200. The rotor plate 404 is a provided with
a plurality of slits 404(a) around its circumference.
[0034] Referring to figure 1(b) and 1(d), the steering angle sensor 300 is
provided with integrally formed flanges 300(a1) on its either side complementary
to the integrally formed flanges 402(a) of the housing 402. The integrally formed
25 flanges 300(a1) of the steering angle sensor (300) are provided with holes
300(a12) complementary to the holes 402(a1) of the housing 402(a). A notch 304 extends from the inner circumference of the steering angle sensor 300 in a freely rotatable condition.
8

[0035] In an aspect, the inner diameter of the housing 402 is slightly more
than the diameter of the inner shaft 204. The housing 402 is press fitted onto the outer jacket 202 of the steering column 200 as shown in figure 1(c).
[0036] In an aspect, the length of the upper portion 202(a) of the outer jacket
5 202 can be either less or more than the lower portion 202(b) of the outer jacket
202 depending on the location of mounting of the steering wheel angle sensor 300.
[0037] The arrangement of the mounting assembly 400 of the steering angle
sensor 300 on a steering column 200 is as follows: Firstly, the housing 402 is
10 press fitted to the upper portion 202(a) of the outer jacket 202. Secondly, the rotor
plate 404 is press fitted onto the inner shaft 204. Thirdly, the steering angle sensor 300 is adapted to pass through the inner shaft 204 to mate with the housing 402 in such a way that the plurality of slits 404(a) of the rotor plate 404 accommodates the notch 304 extending from the steering angle sensor 300. Fourthly, the steering
15 angle sensor 300 held in mating condition with the housing 402 is bolted by
means of a plurality of fasteners passing through the holes 300(a12) of the steering angle sensor 300 and the holes 402(a1) of the housing 402. Fifthly, the lower portion 202(b) of the outer jacket 202 is held in position enclosing the inner shaft 204. .
20 [0038] The working of the steering angle sensor 300 is as follows: the rotor
plate 404 rotates along with the rotation of the inner shaft 204 generated by the rotation of the steering wheel 100. The rotation of the rotor plate 404 in turn rotates the notch 304 extending from the steering angle sensor 300 which thereby facilitates in calculation of the angle of rotation of the steering wheel 100.
25 [0039] It will be understood by those within the art that, in general, terms used
herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as
9

“includes but is not limited to,” etc.). It will be further understood by those within
the art that if a specific number of an introduced claim recitation is intended, such
an intent will be explicitly recited in the claim, and in the absence of such
recitation no such intent is present. For example, as an aid to understanding, the
5 following appended claims may contain usage of the introductory phrases “at least
one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even
10 when the same claim includes the introductory phrases “one or more” or “at least
one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited,
15 those skilled in the art will recognize that such recitation should typically be
interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a
20 construction is intended in the sense one having skill in the art would understand
the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C,
25 etc.” is used, in general such a construction is intended in the sense one having
skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that
30 virtually any disjunctive word and/or phrase presenting two or more alternative
terms, whether in the description, claims, or drawings, should be understood to
10

contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
[0040] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
