Description

Technical Field

[0001] This utility model relates to a spare tire bracket assembly with a locking device. Background Technology

[0002] The spare tire bracket is an important component on a car used to secure and store the spare tire, and its performance directly affects the safety and ease of use of the spare tire. Traditional spare tire brackets are usually fixed to the tailgate using bolts or clips.

[0003] The spare tire is mounted using a bracket assembly. In our practical application, we found that due to the large weight of the spare tire, the traditional single-axle fixing method causes the spare tire to bounce when the vehicle is bumpy, resulting in abnormal noises during vehicle operation. It also causes the axle that suspends the spare tire to bend and deform after being subjected to impact.

[0004] Based on the above problems, we designed a spare tire bracket assembly with a locking device that can secure the spare tire. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a spare tire bracket assembly with a locking device that can fasten the spare tire.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A spare tire bracket assembly with a locking device includes a bracket body fixed to a vehicle tailgate, bolt holes penetrating the surface of the bracket body, a locking assembly fixed to the bracket body, and a lateral clamping device that slides laterally along the bracket body and cooperates with the locking assembly.

[0008] Preferably, the locking assembly includes a base plate and a shaft fixed to the center of the base plate. A threaded hole is machined at the center of the shaft, through which a threaded rod engages. An end cap is machined at the end of the threaded rod, with a diameter larger than that of the threaded rod. A rubber centering sleeve is fitted onto both the shaft and the threaded rod. The centering sleeve has an outer conical surface, with two symmetrical outer conical surfaces. A through hole is radially penetrating the outer wall of the end cap, through which a force rod engages. One end of the force rod has a threaded portion, and the other end has a first end cap, with a diameter larger than that of the through hole. The threaded portion engages with the lateral clamping device. The base plate and the support body are fixed.

[0009] Preferably, a polygonal first bolt hole is machined at the end face of the threaded rod.

[0010] Preferably, the lateral clamping device includes an arc-shaped clamping plate for clamping a tire and an L-shaped bracket fixed to the outer end face of the arc-shaped clamping plate. A sleeve is welded to the inner side of the L-shaped bracket, and the sleeve has an internal threaded hole that matches the threaded portion. The other end of the L-shaped bracket is slidably inserted into the bracket body. A limiting bolt is screwed into the L-shaped bracket near the other end. A groove is provided on the side of the bracket body that passes through the L-shaped bracket. The limiting bolt limits the bracket body from sliding out of the groove.

[0011] Preferably, an arc-shaped pad is fixed to the inner wall of the arc-shaped clamp, and the tire contacts the arc-shaped pad.

[0012] Preferably, a grid groove for anti-slip purposes is injection molded onto the surface of the arc-shaped pad.

[0013] The beneficial effects of this utility model are:

[0014] This device uses a locking assembly that passes through the spare tire's axle for locking. After locking, the spare tire is centered by centering sleeves at both the front and rear ends, reducing the spare tire's movement.

[0015] After locking the spare tire, the locking assembly also incorporates a side clamping device. The locking assembly can tighten the side clamping device, which applies clamping force to the side of the spare tire, further reducing the chance of the spare tire jumping or loosening. At the same time, the side clamping device locks the locking assembly to prevent it from loosening.

[0016] This device can effectively clamp the spare tire, and the clamping is relatively reliable, making it suitable for widespread use. 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.

[0027] See Figure 1 The spare tire bracket assembly with a locking device shown includes a bracket body 1 fixed to the tailgate of a vehicle, with bolt holes 101 penetrating the surface of the bracket body 1, a locking assembly 2 fixed to the bracket body 1, and a lateral clamping device 3 that slides laterally along the bracket body 1 and cooperates with the locking assembly 2.

[0028] In the above technical solution, the bracket body 1 corresponds to the original position of the car door, and the bracket body 1 is fixed to the car door steel frame by means of bolts and bolt holes 101.

[0029] Locking assembly 2 is used to pass through the axle of the spare tire and to lock the spare tire.

[0030] The side clamping device 3 is used to prevent loosening of the locking assembly 2, and secondly, after tightening, it can play an auxiliary role in fixing the spare tire on the side.

[0031] See Figure 1 and Figure 2 As shown, the locking assembly 2 includes a base plate 21 and a shaft 22 fixed at the center of the base plate 21. A threaded hole (not shown) is machined at the center of the shaft 22, and a threaded rod 23 is fitted through the threaded hole. The end of the threaded rod 23 is machined with an end head 24, the diameter of which is larger than the diameter of the threaded rod 23. A rubber centering sleeve 25 is fitted on both the shaft 22 and the threaded rod 23. The centering sleeve 25 has an outer conical surface 26, and the two outer conical surfaces 26 are symmetrical. A through hole 27 is radially penetrating the outer wall of the end head 24, and a force rod 28 is fitted through the through hole 27. One end of the force rod 28 is machined with a threaded portion 281, and the other end is machined with a first end head 282, the diameter of which is larger than the diameter of the through hole 27. The threaded portion 281 is fitted with the lateral clamping device 3. The base plate 21 and the bracket body 1 are fixed.

[0032] The operation method of the above technical solution is as follows:

[0033] When the spare tire needs to be removed, firstly, the lever 28 rotates coaxially along the through hole 27, causing the threaded part 281 to unscrew from the lateral clamping device 3. After unscrewing, the lateral clamping device 3 can move laterally along the bracket body 1, releasing the restriction on the lever 28. Then, rotate the lever 28 clockwise, and under the action of the lever 28, the threaded rod 23 unscrews along the threaded hole until the threaded rod 23 disengages from the shaft 22. At this point, the spare tire can be removed.

[0034] In the above technical solution, the lateral clamping device 3 and the working rod 28 cooperate to lock the position of the working rod 28, thus preventing the threaded rod 23 from loosening.

[0035] See Figure 2 As shown, a polygonal first bolt hole 231 is machined at the end face of the threaded rod 23.

[0036] After removing the threaded rod 23, the bolts on the car tire can be easily unscrewed through the first bolt hole 231, which is used to engage with the tire bolts.

[0037] See Figure 1 , Figure 2 and Figure 3As shown, the lateral clamping device 3 includes an arc-shaped clamping plate 31 for clamping a tire, and an L-shaped bracket 32 ​​fixed to the outer end face of the arc-shaped clamping plate 31. A sleeve 33 is welded to the inner side of the L-shaped bracket 32. The sleeve 33 has an internal threaded hole (not shown) that matches the threaded portion 281. The other end of the L-shaped bracket 32 ​​is slidably inserted into the bracket body 1. A limiting bolt 34 is screwed into the L-shaped bracket 32 ​​near the other end. A groove 121 is provided on the side of the bracket body 1 that passes through the L-shaped bracket 32. The limiting bolt 34 limits the bracket body 1 from sliding out of the groove 121.

[0038] In the above technical solution, the side of the tire is clamped by the arc-shaped clamp 31, reducing the chance of the spare tire becoming loose.

[0039] The engagement of sleeve 33 and threaded portion 281 achieves the anti-loosening function of force rod 28.

[0040] Only after the threaded part 281 and the sleeve 33 are separated can the lever 28 rotate.

[0041] In the above technical solution, by tightening the force rod 28, the arc-shaped clamp 31 will be tightened after the force rod 28 is tightened due to the limiting of the first end 282.

[0042] See Figure 4 As shown, an arc-shaped pad 333 is fixed on the inner wall of the arc-shaped clamp 31, and the tire contacts the arc-shaped pad 333.

[0043] The curved gasket 333 is mainly designed to reduce noise when in contact with the spare tire.

[0044] See Figure 4 As shown, anti-slip mesh grooves 334 are injection molded onto the surface of the arc-shaped pad 333.

[0045] The mesh groove 334 is designed to increase friction when in contact with the spare tire, thereby reducing the rotation of the spare tire.
