[0015] Compared with the prior art, the present invention has at least the following advantages:
[0016] 1. In this utility model, a mounting base is installed in the gap next to the brake pedal to stabilize the entire fixture; the sensor is mounted on a sensor mounting plate; the position of the sensor mounting plate on the adjusting rod is adjusted according to the brake pedal of different vehicle models to adjust the vertical coordinate of the sensor; the position of the adjusting plate in the length direction of the mounting base is adjusted to adjust the longitudinal position of the sensor; the angle between the adjusting rod and the adjusting plate is adjusted to adjust the angle of the sensor; thus, the sensor installation can be completed, and it can be used with brake pedals of different vehicle models, reducing the cost of sensor fixtures when testing brake pedals.
[0017] 2. In this utility model, rotating the adjusting rod causes the insert rod to rotate within the circular insertion interface, which in turn causes the circular abutment plate and the limiting member to rotate. Guided by the side of the limiting member and the inner wall of the limiting groove, the limiting member slides out of the limiting groove, thereby driving the insert rod to move in the axial direction of the circular insertion interface and compressing the spring. When the limiting member moves to the next limiting groove, the compressed spring pushes the limiting member into the next limiting groove through the circular abutment plate. Thus, by moving the limiting member to different limiting grooves, the angle of the adjusting rod can be adjusted. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] See Figures 1-3 The present invention provides an embodiment of a universal tooling for a brake pedal sensor, comprising: a fixed base 1, an adjusting plate 2, an adjusting rod 3, a sensor mounting plate 4, and an angle adjustment mechanism 5; the adjusting plate 2 is mounted on the fixed base 1, and the position of the adjusting plate 2 in the length direction of the fixed base 1 is adjustable; the sensor mounting plate 4 is mounted on the adjusting rod 3, and the position of the sensor mounting plate 4 in the length direction of the adjusting rod 3 is adjustable; one end of the adjusting rod 3 is mounted on the adjusting plate 2 through the angle adjustment mechanism 5 to adjust the included angle between the adjusting rod 3 and the adjusting plate 2.
[0027] In practice, the mounting base 1 is installed in the gap next to the brake pedal to stabilize the entire fixture; the sensor is installed on the sensor mounting plate 4; the position of the sensor mounting plate 4 on the adjusting rod 3 is adjusted according to the different vehicle models' brake pedals to adjust the vertical coordinate of the sensor; the position of the adjusting plate 2 in the length direction of the mounting base 1 is adjusted to adjust the longitudinal position of the sensor; the angle between the adjusting rod 3 and the adjusting plate 2 is adjusted to adjust the angle of the sensor; in this way, the installation of the sensor can be completed, and it can be used with brake pedals of different vehicle models, reducing the cost of the sensor fixture when testing the brake pedal.
[0028] See Figures 1-3 In other embodiments, the device also includes an extension member 6 and a first bolt. The extension member 6 is slidably inserted into the fixed base 1 along its length. The fixed base 1 has a first insertion hole 11 for the first bolt to pass through, and the extension member 6 has multiple first threaded holes 61 evenly distributed along its length to mate with the first bolt. In specific implementation, the extension member 6 is slid so that the first insertion hole 11 on the fixed base 1 is aligned with the corresponding first threaded hole 61. Then, the first bolt is passed through the first insertion hole 11 and screwed into the corresponding first threaded hole 61. This allows the total length between the extension member 6 and the fixed base 1 to be adjusted according to the different lengths of the cab floor of different vehicle models, thereby ensuring that both ends of the extension member 6 and the fixed base 1 abut against the cab to achieve stability of the entire fixture. Furthermore, the first insertion hole 11 is elongated along the length of the fixed base 1, and multiple first insertion holes 11 are provided along the length of the fixed base 1; this allows for fine-tuning of the total length between the extension member 6 and the fixed base 1.
[0029] See Figures 1-3 In other embodiments, the system further includes: a second bolt; a second insertion hole 21 for the second bolt to pass through on the adjusting plate 2; and multiple second threaded holes 12 that mate with the second bolt evenly distributed along the length of the fixing base 1. In specific implementation, the position of the adjusting plate 2 on the fixing base 1 is adjusted so that the second insertion hole 21 on the adjusting plate 2 aligns with the corresponding second threaded hole 12. Then, the second bolt is passed through the second insertion hole 21 and screwed into the corresponding second threaded hole 12, thus achieving adjustment of the position of the adjusting plate 2 on the fixing base 1. Furthermore, the second insertion hole 21 is elongated along the length of the fixing plate, allowing for fine-tuning of the position of the adjusting plate 2.
[0030] See Figures 1-3 In other embodiments, two parallel second guide plates 22 are fixedly installed on the side of the adjusting plate 2 near the fixed base 1. The two second guide plates 22 slide against opposite sides of the fixed base 1 in the width direction. By setting the two second guide plates 22, it is possible to effectively prevent the adjusting plate 2 from rotating around the second bolt when it is installed on the fixed base 1 by the second bolt, thus affecting the accuracy of the sensor installation.
[0031] See Figures 1-3In other embodiments, the device further includes: a third bolt; a third insertion hole 41 for the third bolt to pass through on the sensor mounting plate 4; and multiple third threaded holes 31 that mate with the third bolt evenly distributed along the length of the adjusting rod 3. In specific implementation, the position of the sensor mounting plate 4 on the adjusting rod 3 is adjusted so that the third insertion hole 41 on the sensor mounting plate 4 aligns with the corresponding third threaded hole 31. Then, the third bolt is passed through the third insertion hole 41 and screwed into the corresponding third threaded hole 31, thus adjusting the position of the sensor mounting plate 4 on the adjusting rod 3. Furthermore, the third insertion hole 41 is elongated along the length of the adjusting rod 3, allowing for fine-tuning of the position of the sensor mounting plate 4.
[0032] See Figures 1-3 In other embodiments, two parallel third guide plates 42 are fixedly installed on the side of the sensor mounting plate 4 near the adjusting rod 3. The two third guide plates 42 slide against opposite sides of the adjusting rod 3 in the width direction. By setting the two third guide plates 42, it is possible to effectively prevent the sensor mounting plate 4 from rotating around the third bolt when it is installed on the adjusting rod 3 by the third bolt, thus affecting the accuracy of the sensor installation.
[0033] See Figures 1-3 In another embodiment, the angle adjustment mechanism 5 includes: a housing 51, a rod 52, a circular abutment plate 53, a limiting member 54, and an elastic member 55; the housing 51 is mounted on the adjusting plate 2; one end of the housing 51 has a circular insertion interface 56 that engages with the rod 52, and the circular insertion interface 56 is coaxially arranged with the housing 51; one end of the rod 52 is inserted into the housing 51 through the circular insertion interface 56, and the end of the rod 52 located inside the housing 51 is coaxially mounted with the circular abutment plate 53, which is slidably engaged with the inside of the housing 51; the other end of the rod 52 is vertically mounted on one end of the adjusting rod 3; the limiting member 55... The limiting member 54 is fixedly installed on the side of the circular abutment plate 53 near the adjusting rod 3, and the end of the limiting member 54 away from the axis of the circular abutment plate 53 is triangularly arranged. The end of the limiting member 54 facing the axis of the circular abutment plate 53 decreases to a straight line parallel to the axis of the circular abutment plate 53, so that the two sides of the limiting member 54 are inclined. The inner side wall of the box body 51 with the circular insertion interface 56 is provided with a limiting groove 57 that cooperates with the limiting member 54. Multiple limiting grooves 57 are evenly arranged along the circumferential direction of the box body 51. The elastic member 55 applies an elastic thrust to the circular abutment plate 53 towards the limiting groove 57.
[0034] In specific implementation, the elastic element 55 is a spring; rotating the adjusting rod 3 causes the insertion rod 52 to rotate within the circular insertion interface 56, and the insertion rod 52 causes the circular abutment plate 53 and the limiting element 54 to rotate; under the guidance of the side of the limiting element 54 and the inner wall of the limiting groove 57, the limiting element 54 slides out from the limiting groove 57, thereby driving the insertion rod 52 to move in the axial direction of the circular insertion interface 56, compressing the spring; when the limiting element 54 moves to the next limiting groove 57, the compressed spring pushes the limiting element 54 into the next limiting groove 57 through the circular abutment plate 53; thus, by moving the limiting element 54 into different limiting grooves 57, the angle of the adjusting rod 3 can be adjusted. Furthermore, the box body 51 includes an outer shell and two end caps, which are respectively threaded onto both ends of the outer shell; the circular insertion interface 56 and the limiting groove 57 are formed on one of the end caps. Furthermore, multiple limiting members 54 are evenly arranged along the circumferential direction of the box body 51, and the limiting members 54 are arranged one-to-one with the limiting grooves 57; thus, the angle of the adjusting rod 3 can be adjusted more conveniently.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
