Description

Technical Field

[0001] This utility model relates to the field of car carrier equipment technology, and more specifically, to a locking structure for a car carrier pedal assembly. Background Technology

[0002] A car carrier is a commercial vehicle specifically designed for transporting cars. It is a special type of transport vehicle, mainly used for bulk transport of new or used cars. It can also be used for vehicle rescue, exhibitions, and other scenarios. Through its multi-layer rack design, it achieves efficient transport and can carry multiple cars at a time, far exceeding the capacity of ordinary trucks.

[0003] The step on a car carrier usually refers to a transitional device used to facilitate loading and unloading of the vehicle. The tail step is located at the rear of the car carrier and can be raised, lowered or tilted to connect the ground with the vehicle's cargo platform, forming a ramp. It is commonly found in hydraulic tailgate designs, which facilitates the vehicle to drive into or out of the cargo box. Traditional car carrier tail steps are prone to loosening due to bumps and vibrations during vehicle operation, causing the tail step to wobble or make abnormal noises, affecting driving safety. After long-term use, they are also prone to deformation or wear. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a locking structure for the car carrier pedal assembly. This structure can effectively prevent the rear pedal from becoming loose or making abnormal noises due to bumps or vibrations during the car carrier's operation, thereby improving driving safety, reducing wear on the rear pedal caused by vibration, and extending the service life of the rear pedal.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A locking structure for a car carrier pedal assembly includes: a rear-end support box, with two drive threaded rods rotatably connected between the upper and lower inner walls of the rear-end support box; two sets of locking rods slidably passing through the upper inner wall of the rear-end support box, each set of four locking rods; a drive plate fixedly connected to the lower end of each set of four locking rods; and two drive plates threadedly connected to the two drive threaded rods respectively.

[0009] A synchronous drive assembly is disposed at the bottom of the tail support box, and the synchronous drive assembly is used to control the synchronous rotation of two transmission threaded rods.

[0010] As a preferred embodiment of this utility model, the synchronous drive assembly includes two synchronous pulleys, both of which are rotatably connected to the bottom of the tail support box. The two synchronous pulleys are fixedly connected to two transmission threaded rods respectively, and the two synchronous pulleys are connected by a synchronous belt drive.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, this utility model provides a locking structure for a car carrier pedal assembly, which has the following advantages:

[0017] The locking structure of this car carrier's pedal assembly allows the tail pedal to retract into the car carrier's transport frame, where it rests against the top of the rear support box. The eight locking holes in the tail pedal correspond to two sets of eight locking rods. By controlling the drive motor to start, the corresponding synchronous pulleys rotate, causing the two transmission threaded rods to rotate synchronously, which in turn causes the two transmission plates to rise synchronously, raising the two sets of locking rods. This allows the eight locking rods to insert into the eight locking holes on the tail pedal, effectively preventing the tail pedal from loosening or making abnormal noises due to bumps or vibrations during driving. This improves driving safety, reduces wear on the tail pedal caused by vibration, and extends the lifespan of the tail pedal. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Example:

[0026] Please see Figures 1-4 A locking structure for a car carrier pedal assembly includes: a rear support box 1, with two drive threaded rods rotatably connected between the upper and lower inner walls of the rear support box 1; two sets of locking rods slidably passing through the upper inner wall of the rear support box 1, each set of locking rods 5 having four rods; a drive plate 6 is fixedly connected to the lower end of each set of four locking rods 5; and the two drive plates 6 are threadedly connected to the two drive threaded rods 7 respectively.

[0027] The synchronous drive assembly is located at the bottom of the tail support box 1 and is used to control the synchronous rotation of the two transmission threaded rods 7.

[0028] In a specific embodiment of this utility model, the tail support box 1 is fixedly installed at the tail end of the car carrier. The tail pedal of the car carrier has eight locking holes near the tail end. When the tail pedal of the car carrier is retracted into the transport frame of the car carrier, the tail pedal will fit against the top of the tail support box 1. The eight locking holes of the tail pedal of the car carrier will correspond to the two sets of eight locking rods 5. The synchronous drive assembly drives the two transmission threaded rods 7 to rotate synchronously, drives the two transmission plates 6 to rise synchronously, and drives the two sets of locking rods 5 to rise, so that the eight locking rods 5 are inserted into the eight locking holes on the tail pedal of the car carrier. This effectively prevents the tail pedal from becoming loose or making abnormal noise due to bumps or vibrations during the operation of the car carrier, improves driving safety, reduces wear on the tail pedal of the car carrier caused by vibration, and extends the service life of the tail pedal of the car carrier.

[0029] Specifically, the synchronous drive assembly includes two synchronous pulleys 9, both of which are rotatably connected to the bottom of the tail support box 1. The two synchronous pulleys 9 are fixedly connected to two transmission threaded rods 7 respectively, and the two synchronous pulleys 9 are connected by a synchronous belt drive.

[0030] In this embodiment, the two synchronous pulleys 9 are kept rotating synchronously by a synchronous belt, so that the two synchronous pulleys 9 will drive the two transmission threaded rods 7 to rotate synchronously.

[0031] Specifically, the synchronous drive assembly also includes a protection box 3, which is fixedly connected to the bottom of the tail support box 1, and both synchronous wheels 9 are located inside the protection box 3.

[0032] In this embodiment, the protective box 3 protects the two synchronous pulleys 9 from being exposed.

[0033] Specifically, the synchronous drive assembly also includes a drive motor 4, which is fixedly installed at the bottom of the protective box 3, and the output end of the drive motor 4 is fixedly connected to one of the synchronous pulleys 9.

[0034] In this embodiment, by controlling the start of the drive motor 4, the corresponding synchronous wheel 9 can be driven to rotate, thereby causing the two synchronous wheels 9 to rotate.

[0035] Specifically, two sets of limiting rods 8 are fixedly connected between the upper and lower inner walls of the tail support box 1. Each set of limiting rods 8 has two rods, and each transmission plate 6 is slidably sleeved on the corresponding two limiting rods 8.

[0036] In this embodiment, the two limiting rods 8 in each group ensure the stability of the corresponding transmission plate 6 during its up-and-down movement, thereby increasing the overall structural stability.

[0037] Specifically, multiple connecting rods 2 are fixedly connected to one side of the outer surface of the tail support box 1.

[0038] In this embodiment, multiple connecting rods 2 are used to install the tail support box 1 to the tail end of the car carrier's transport frame.

[0039] Working principle: When the rear step of the car carrier is retracted into the car carrier's transport frame, the rear step will fit against the top of the rear support box 1. The eight locking holes of the rear step will correspond to the two sets of eight locking rods 5. By controlling the start of the drive motor 4, the corresponding synchronous wheel 9 will rotate, which will drive the two transmission threaded rods 7 to rotate synchronously, drive the two transmission plates 6 to rise synchronously, and drive the two sets of locking rods 5 to rise, so that the eight locking rods 5 are inserted into the eight locking holes on the rear step of the car carrier. This effectively prevents the rear step from becoming loose or making abnormal noises due to bumps or vibrations during the car carrier's operation, improves driving safety, reduces wear on the rear step caused by vibration, and extends the service life of the rear step.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
