Abstract
Description
Technical Field
[0001] This application relates to the field of bushing and pedal technology, and in particular to a bushing and pedal capable of eliminating gaps. Background Technology
[0002] The bushing in the pedal is a key component. The bushing is fitted on the pedal's pivot and is mainly used to buffer vibration, reduce friction, and ensure smooth pedal operation.
[0003] When the existing bushing is fitted onto the rotating shaft, the shaft has a circumferential clearance and a lateral clearance, causing it to wobble when rotating.
[0004] Therefore, we propose a bushing and pedal that can eliminate gaps. Utility Model Content
[0005] In response to the shortcomings of the existing production technology, the applicant provides a bushing and pedal that can eliminate gaps. By eliminating gaps in the circumferential direction and at both ends of the shaft through the two bushings, the amount of shaft wobble is reduced, thereby making the magnet on the shaft more stable, improving the accuracy of the electrical signal, and further enhancing product performance.
[0006] The technical solution adopted in this application is as follows:
[0007] A bushing capable of eliminating gaps, comprising:
[0008] The circular part is cylindrical in shape;
[0009] The connecting part is plate-shaped and is fixedly connected to the annular part;
[0010] In the first direction, a clamping part is provided at the end of the annular part away from the connecting part, and the clamping part is inclined towards the center line of the annular part; the clamping part clamps the rotating shaft of the pedal body;
[0011] In the second direction, a deformable part is provided at the end of the connecting part away from the annular part. The deformable part is inclined towards the center line of the annular part, and a plurality of protrusions are provided on the surface of the deformable part.
[0012] Its further features are:
[0013] The annular portion and the connecting portion are an integral structure.
[0014] The connecting part is fixed to one end of the outer surface of the ring part in the first direction.
[0015] The deformable part and the clamping part are inclined to the same side.
[0016] In the first direction, the bushing is provided with a through hole penetrating the annular portion.
[0017] The clamping part has multiple grooves on its circumference, and the connecting part and the deformable part also have multiple grooves on their circumferences.
[0018] The groove depth on the clamping part is less than the groove depth on the connecting part and the deformable part.
[0019] There is an included angle between the connecting part and the annular part.
[0020] This application also discloses a pedal, comprising:
[0021] The pedal body has a rotating shaft on it.
[0022] Two bushings capable of eliminating gaps as described in any one of claims, the two bushings being respectively fitted onto both ends of the rotating shaft.
[0023] A magnet is provided at one end of the rotating shaft, and a protective plate is provided on the outside of the pedal body. A sensing sensor is provided on the protective plate, and the sensing sensor is set in correspondence with the magnet.
[0024] The beneficial effects of this application are as follows:
[0025] This application features a compact and reasonable structure, and is easy to operate. Both ends of the pedal's rotating shaft are fitted with a bushing, and the annular part of the bushing is fitted onto the rotating shaft. The clamping part can clamp the rotating shaft of the pedal body to eliminate the gap in the rotating shaft axis. The surface of the deformable part is provided with multiple protrusions. The deformable part and the protrusions cooperate to eliminate the gap. The gaps on both sides are eliminated by the deformable parts and protrusions on both sides, thereby eliminating the gaps in the circumferential direction and both sides of the rotating shaft, making the rotating shaft more stable.
[0026] In addition, this application also has the following advantages:
[0027] (1) A magnet is provided at one end of the rotating shaft, and a protective plate is provided on the outside of the magnet on the pedal body. A sensing sensor is provided on the protective plate. The sensing sensor is set in correspondence with the magnet. The gaps in the circumference and both ends of the rotating shaft are eliminated by the two bushings, reducing the amount of shaking of the rotating shaft. This makes the magnet on the rotating shaft more stable, which can improve the accuracy of the electrical signal and further improve the product performance. Attached Figure Description

[0036] The specific embodiments of this application are described below with reference to the accompanying drawings.
[0037] like Figures 1-5 As shown, a bushing capable of eliminating gaps includes an annular portion 1, a clamping portion 2, a connecting portion 3, and a deformable portion 4.
[0038] The annular part 1 is cylindrical, and the connecting part 3 is plate-shaped. The annular part 1 and the connecting part 3 are fixedly connected.
[0039] In one embodiment, the connecting portion 3 is fixed to one end of the outer surface of the annular portion 1 in a first direction.
[0040] In one embodiment, the annular portion 1 and the connecting portion 3 are an integral structure.
[0041] In the first direction, the bushing is provided with a through hole 1 through the annular portion.
[0042] In the first direction, the end of the annular portion 1 away from the connecting portion 3 is provided with a clamping portion 2.
[0043] The clamping part 2 is inclined toward the center line of the annular part 1, so that the clamping part 2 can clamp the pivot 5 of the pedal body 6.
[0044] In one embodiment, the clamping part 2 has a plurality of grooves on its circumference.
[0045] In the second direction, a deformable part 4 is provided at the end of the connecting part 3 away from the annular part 1.
[0046] The deformable part 4 is inclined toward the center line of the annular part 1.
[0047] In one embodiment, the deformable part 4 and the clamping part 2 are inclined to the same side.
[0048] In one embodiment, the connecting part 3 and the deformable part 4 are provided with a plurality of grooves on their circumferences.
[0049] like Figure 1 As shown, the depth of the groove on the clamping part 2 is less than the depth of the groove on the connecting part 3 and the deformable part 4.
[0050] like Figure 3 As shown, there is an included angle between the connecting part 3 and the annular part 1.
[0051] Specifically, the included angle is close to 90°, but it could also be other possible angles.
[0052] like Figure 4 As shown, both sides of the clamping part 2 are inclined towards the center line of the annular part 1.
[0053] like Figure 5 As shown, both sides of the deformable part 4 are inclined towards the center line of the annular part 1.
[0054] The surface of the deformable part 4 is provided with a plurality of protrusions 7, and the deformable part 4 and the protrusions 7 cooperate to eliminate gaps.
[0055] like Figures 6-7 As shown, a pedal includes a pedal body 6, the pedal body 6 includes a rotating shaft 5, and bushings are provided at both ends of the rotating shaft 5. The rotating shaft 5 is clamped by the clamping part 2 of the bushing, eliminating the gap around the circumference of the rotating shaft 5.
[0056] The gaps on the left and right sides are eliminated by the deformation part 4 of the two bushings.
[0057] In one embodiment, a magnet is provided at one end of the rotating shaft 5, and a protective plate is provided on the outside of the magnet on the pedal body 6. A sensing sensor is provided on the protective plate, and the sensing sensor is correspondingly arranged with the magnet. The gaps in the circumference and both ends of the rotating shaft 5 are eliminated by the two bushings, reducing the amount of shaking of the rotating shaft 5. This makes the magnet on the rotating shaft 5 more stable, which can improve the accuracy of the electrical signal and further improve the product performance.
[0058] The above description is an explanation of this application and not a limitation thereof. The scope of this application is defined by the claims. Within the scope of protection of this application, any form of modification may be made.
