Description

Technical Field

[0001] This utility model relates to the field of spare tire installation technology for transport vehicles, specifically to an electric lifter for spare tires on transport vehicles. Background Technology

[0002] A spare tire for a transport vehicle is a spare tire installed on the vehicle. Its primary purpose is to quickly replace a tire in case of a blowout, damage, or other malfunction during transit, ensuring the vehicle continues to operate normally and reducing delays and safety risks. Its important function is to respond to emergencies and ensure the continuity and safety of transportation, making it indispensable, especially for long-distance transport or travel in remote areas. Currently, spare tires are typically stored using chains and winding devices. When in use, only tools compatible with the winding device are needed to control and lower the spare tire. However, using tools to store the spare tire is relatively inconvenient. On one hand, it requires the appropriate tools for control; on the other hand, it requires a certain amount of effort. Furthermore, the brackets used to install the spare tire are usually in relatively fixed positions. Since spare tires vary in size and mounting hole positions, if the brackets cannot be effectively adjusted, the spare tire may not be able to be installed, thus reducing the effectiveness of the spare tire lifter.

[0003] Therefore, it is necessary to develop an electric lifter for the spare tire of transport vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide an electric lifter for the spare tire of a transport vehicle, so as to solve the problems mentioned in the background art, such as the cumbersome operation of lifting the spare tire of a transport vehicle using tools and the inability to adapt to different mounting hole positions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric lifter for a spare tire of a transport vehicle, including a vehicle body fixing frame, a take-up roller rotatably connected to one side of the bottom of the vehicle body fixing frame, a rotating shaft A installed at one end of the take-up roller, and a gear A provided on the outer wall of the rotating shaft A;

[0006] A motor is installed on the other side of the top of the vehicle body mounting bracket, and an iron chain is provided on the outer wall of the winding roller, with a spare tire bracket installed at one end of the iron chain.

[0007] Preferably, a hexagonal head is installed at one end of the rotating shaft A.

[0008] Preferably, the output shaft of the motor is fixedly connected to one end of the rotating shaft B via a coupling, and a gear B is provided on the outer wall of the rotating shaft B.

[0009] Preferably, the teeth on gear B mesh with the teeth on gear A.

[0010] Preferably, guide grooves are provided on both sides of the surface of the spare tire bracket, and a T-shaped seat is installed inside the guide groove.

[0011] Preferably, the upper part of the outer wall of the T-shaped seat is slidably connected to the inside of the guide groove, and a nut is installed on the upper part of the outer wall of the T-shaped seat.

[0012] Preferably, the inside of the nut is threaded to the outer wall of the T-shaped seat, and a bolt is installed at the top of the T-shaped seat, with the outer wall of the bolt threaded to the inside of the top of the T-shaped seat.

[0013] Preferably, a positioning frame is installed on the lower side of the take-up roller, a movable plate is installed on the upper side of the positioning frame, guide posts are provided on both sides of the bottom of the movable plate, the guide posts are slidably connected to the positioning frame, a limit pin is provided on the top of the movable plate, and a cylinder is installed on the bottom side of the positioning frame, with the output end of the cylinder fixedly connected to the bottom of the movable plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By installing gear B on the outer wall of the motor's rotating shaft B and meshing the teeth of gear B with gear A on the rotating shaft A, and by using a tool with the hexagonal head on the rotating shaft A to wind up and unwind the chain on the winding roller, a manual operation can be achieved. Alternatively, by controlling the motor switch to start and stop the motor, an automatic operation can be achieved. These two different drive methods improve flexibility.

[0016] By fixing the spare tire bracket to the end of the chain, and with two sets of T-shaped seats slidingly positioned in the guide grooves on the spare tire bracket, the position of the T-shaped seats can be adjusted according to the mounting hole position of the spare tire on the transport vehicle. After adjustment, tightening the nuts will fix the position of the T-shaped seats. Once the T-shaped seats align with the mounting holes on the spare tire, bolts are used for installation and fixation, thus completing the installation of the spare tire. Depending on the installed spare tire, two different drive methods can be used to lift it. By making the spacing of the T-shaped seats adjustable, the installation of spare tires of different sizes can be avoided, which could lead to installation problems or difficulties in subsequent lifting. This effectively improves the usability of the electric spare tire lifter. Attached Figure Description

[0026] Working principle: When using this utility model, the rotating shaft A3 on the take-up roller 2 is rotatably connected to the vehicle body fixing frame 1, and a hexagonal head 5 is installed on one end of the rotating shaft A3. By matching the tool with the hexagonal head 5, the take-up roller 2 on the rotating shaft A3 can be rotated forward or backward. By setting a gear B8 on the outer wall of the rotating shaft B7 on the motor 6, and meshing the teeth of the gear B8 with the gear A4 on the rotating shaft A3, the chain 9 is wound onto the take-up roller 2, and the take-up roller 2 is fixedly connected to the rotating shaft A3. By using a tool with the hexagonal head 5 on its rotating shaft A3, the chain 9 on the winding roller 2 can be wound and unwound, achieving a manual effect. By controlling the motor 6 switch to start and stop the motor 6, the chain 9 on the winding roller 2 can be wound and unwound, achieving an automatic effect. The two different drive methods improve flexibility. By fixing the spare tire bracket 10 to the end of the chain 9, and with two sets of T-shaped seats 12 slidably set in the guide groove 11 on the spare tire bracket 10, the spare tire can be wound and unwound according to the spare tire of the transport vehicle. The T-shaped seat 12 can be moved and adjusted to its position. After adjustment, tighten the nut 13 to fix the T-shaped seat 12 in place. Once the T-shaped seat 12 aligns with the mounting hole on the spare tire of the transport vehicle, use bolts 14 to install and fix it, thus completing the installation of the spare tire. Depending on the installed spare tire, two different drive methods can be used to lift it. By making the spacing of the T-shaped seat 12 adjustable, it is possible to avoid situations where different sizes of spare tires cannot be installed or lifted due to different mounting hole positions. At the same time, the guide post 17 on the moving plate 16 is slidably connected to the upper part of the positioning frame 15, and the output end of the cylinder 19 at the bottom of the positioning frame 15 is fixedly connected to the moving plate 16, so that the cylinder 19 can drive and control the limit pin 18 on the moving plate 16, which engages with the tooth gap on the gear A4, thereby achieving a self-locking effect and minimizing the possibility of the installed spare tire falling off. This effectively improves the performance of the electric lifter for the spare tire.
