Description

Technical Field

[0001] This utility model relates to the field of vehicle winch technology, and in particular to a quick-release mounting bracket for vehicle winches. Background Technology

[0002] A vehicle-mounted winch is a towing device installed on a vehicle for self-rescue and rescue in extreme environments or emergency situations. It is widely used in off-road and engineering rescue fields. Its core components include an electric or mechanical winch, steel cable or synthetic fiber rope, and control device. The winch drum is driven by an electric motor to rotate, and the cable is wound up and down to achieve towing of the target object. The maximum towing weight ranges from several tons to tens of tons. It can help vehicles get out of mud and sand, or tow disabled vehicles and heavy equipment.

[0003] With the expansion of automotive outdoor applications, vehicle winches are increasingly required to be easy to install and stable in operation. They need to ensure traction performance, adapt to different vehicle operating conditions, and be easy to install, disassemble, and maintain.

[0004] Existing vehicle-mounted winch mounting brackets are mostly fixed by welding or connected to the vehicle body by multiple sets of bolts. The welding method directly welds the winch bracket to the vehicle frame as one piece, and the high temperature fusion of metals makes the bracket stable and avoids safety hazards caused by loose connections. The multiple bolt fixing method uses densely arranged bolts to tightly connect the bracket to the vehicle body, and uses the tightening force of the bolts to provide reliable support. However, both of these methods have significant drawbacks when repairing or replacing the winch. If the welded bracket needs to be disassembled, cutting equipment is required to destroy the weld points. This is not only complicated and time-consuming, but it is also easy to damage the vehicle frame structure, increasing repair costs and safety risks. Although the multiple bolt fixing method can be disassembled by loosening the bolts, the large number of bolts and their dense arrangement make the disassembly process cumbersome and require the use of various socket wrenches. This is difficult to meet the actual needs of rapid disassembly and assembly and stable operation of vehicle-mounted winches in outdoor emergency situations. Utility Model Content

The bottom of each mounting plate is fixedly connected to a sponge pad, and mounting bolts penetrate the four corners of the top of each mounting plate. Anti-loosening washers are fitted in the middle of each of the mounting bolts.

[0010] As a further description of the above technical solution:

[0011] The shock absorption mechanism also includes two L-shaped rubber pads and two straight rubber pads. The two L-shaped rubber pads are fixedly connected to the top left and right ends of the L-shaped connector, respectively. Both L-shaped rubber pads adopt an arc design. The two straight rubber pads are fixedly connected to the top front and rear sides of the L-shaped connector, respectively.

[0012] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] The wear-resistant component includes two fixing plates, which are respectively fixedly connected to the left and right ends of the front side inside the mounting box. Two steel rotating cylinders are rotatably connected between the two fixing plates.

[0033] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 2-6 An embodiment of this utility model provides a vehicle winch quick-release mounting bracket, including a mounting box 1, a winch 2 fixedly connected inside the mounting box 1, a quick-release mechanism 3 fixedly connected to the rear side of the mounting box 1, the quick-release mechanism 3 being used to quickly disassemble the mounting box 1, and a shock-absorbing mechanism 4 being provided at the bottom of the quick-release mechanism 3, the shock-absorbing mechanism 4 being used to connect with the vehicle frame.

[0035] The quick-release mechanism 3 includes an L-shaped connector 301. A steel plate 302 is fixedly connected to the inner side of the L-shaped connector 301. I-beam grooves 303 are provided on the rear side of the steel plate 302 and the rear side of the inner side of the mounting box 1. Connecting sliders 304 are engaged inside the multiple I-beam grooves 303. Two connecting sliders 304 are fixed by a locking assembly 305. The locking assembly 305 includes a locking screw 3051, which passes through the interior of the L-shaped connector 301. A long nut 3052 is threaded to the outer right end of the locking screw 3051. The locking assembly 305 also includes a hexagonal head 3. 053, a hexagonal head 3053 is fixedly connected to the left end of the locking screw 3051. A fixing ring 3054 is fixedly connected to the left side of the hexagonal head 3053. A longitudinal fixing bolt 306 passes through the bottom of the L-shaped connector 301. The top of the longitudinal fixing bolt 306 is threadedly connected to the bottom of the mounting box 1. A wear-resistant component 307 is provided on the front side of the interior of the mounting box 1. The wear-resistant component 307 includes two fixing plates 3071. The two fixing plates 3071 are fixedly connected to the left and right ends of the front side of the interior of the mounting box 1, respectively. Two steel rotating cylinders 3072 are rotatably connected between the two fixing plates 3071.

[0036] Specifically, in the quick-release mechanism 3, the steel plate 302 fixed inside the L-shaped connector 301 and the I-beam groove 303 opened inside the rear of the mounting box 1 form a basic connection structure. The connecting slider 304 is inserted into the I-beam groove 303, so that the L-shaped connector 301 and the mounting box 1 are initially positioned. The locking component 305 is used for fastening the connection. The locking screw 3051 passes through the L-shaped connector 301, and its outer right end is threaded through the elongated nut 3052. The operator uses a tool to rotate the hexagonal head 3053, which drives the locking screw 3051 to rotate, so that the elongated nut 3052 is tightly fitted with the right side of the L-shaped connector 301, generating a fastening force and firmly securing the connecting slider 304. Securely fixed within the I-beam groove 303, the L-shaped connector 301 is firmly connected to the mounting box 1. The fixing ring 3054 fixed on the left side of the hexagonal head 3053 can be manually rotated to loosen the locking screw 3051. Simultaneously, the longitudinal fixing bolt 306 at the bottom of the L-shaped connector 301 passes through its bottom and is threaded to the bottom of the mounting box 1, further strengthening the connection from below. Through the engagement and positioning of the I-beam groove 303 and the connecting slider 304, the threaded fastening of the locking screw 3051 and the elongated nut 3052, and the auxiliary reinforcement of the longitudinal fixing bolt 306, a quick and secure connection between the mounting box 1 and the L-shaped connector 301 is achieved. The connection effect facilitates quick assembly and disassembly of the mounting box 1. In the wear-resistant component 307 inside the front of the mounting box 1, two fixing plates 3071 are respectively fixed to the left and right ends of the front side of the mounting box 1, providing mounting support for the steel rotating drum 3072. The two steel rotating drums 3072 are rotatably connected between the two fixing plates 3071. When the winch 2 is working, the steel cable contacts the steel rotating drum 3072 and generates friction. The steel rotating drum 3072 can rotate under the action of friction, converting sliding friction into rolling friction, reducing direct wear between the steel cable and the inner wall of the mounting box 1. Through the combined arrangement of the fixing plates 3071 and the steel rotating drum 3072, wear resistance of the steel cable is achieved. To enhance protection and extend the service life of the steel cable, the L-shaped connector 301 of the quick-release mechanism 3 is connected to the shock-absorbing mechanism 4. The shock-absorbing mechanism 4 is used to fix the vehicle frame. When the vehicle is driving on a bumpy road, the shock-absorbing mechanism 4 absorbs and buffers the vibration from the road surface, reducing the vibration transmitted to the mounting box 1 and the winch 2, and avoiding loosening of the connection or damage to the equipment due to vibration. The quick-release mechanism 3 enables the installation box 1 to be quickly installed and removed. The wear-resistant component 307 ensures the durability of the steel cable. The shock-absorbing mechanism 4 improves the stability of the equipment operation. The three work together to ensure that the vehicle-mounted winch mounting bracket can meet the needs of quick installation and disassembly while ensuring the reliable operation of the winch 2 under complex road conditions.

[0037] Reference Figure 3 and Figure 5The damping mechanism 4 includes two triangular braces 401, which are fixedly connected to the left and right rear ends of the L-shaped connector 301. Mounting plates 402 are fixedly connected to the bottom of each of the two triangular braces 401. The tops of the two mounting plates 402 are fixedly connected to the left and right bottom ends of the L-shaped connector 301. Sponge pads 403 are fixedly connected to the bottom of each of the two mounting plates 402. Mounting bolts 404 penetrate the four corners of the top of the mounting plates 402. Anti-loosening washers 405 are fitted in the middle of each of the mounting bolts 404. The damping mechanism 4 also includes two L-shaped rubber pads 406 and two straight rubber pads 407. The two L-shaped rubber pads 406 are fixedly connected to the left and right top ends of the L-shaped connector 301, and both L-shaped rubber pads 406 have an arc-shaped design. The two straight rubber pads 407 are fixedly connected to the front and rear top sides of the L-shaped connector 301.

[0038] Specifically, two triangular braces 401 are fixed to the left and right rear ends of the L-shaped connector 301, respectively, and the bottom is connected to the mounting plate 402. The top of the mounting plate 402 is fixedly connected to the left and right bottom ends of the L-shaped connector 301, forming a stable triangular support structure. The sponge pad 403 at the bottom of the mounting plate 402 acts as a buffer medium when the mounting bracket is connected to the vehicle frame. The mounting bolt 404 passes through the four corners of the top of the mounting plate 402, and the anti-loosening washer 405 in the middle can prevent the mounting bolt 404 from loosening during vehicle vibration. The triangular braces 401 and the mounting plate 402 form a stable support, and with the buffering of the sponge pad 403 and the anti-loosening washer 405 preventing the mounting bolt 404 from loosening, the stability of the connection between the mounting bracket and the vehicle frame and the initial vibration reduction effect are achieved, reducing the rigid vibration transmission caused by direct contact between the bracket and the frame. The L-shaped rubber pad 406 and the straight rubber pad 407 further enhance the stability of the connection between the mounting bracket and the vehicle frame and the initial vibration reduction effect. To enhance shock absorption, two L-shaped rubber pads 406 with an arc design are fixed to the top left and right ends of the L-shaped connector 301, and two straight rubber pads 407 are fixed to the front and rear sides of the top of the L-shaped connector 301. When the vehicle encounters bumpy road conditions, the vibration generated by the mounting box 1 and the winch 2 will be transmitted to the L-shaped connector 301. The L-shaped rubber pads 406 and the straight rubber pads 407 absorb and disperse the vibration energy through their own elastic deformation, reducing the impact of vibration on the mounting box 1 and the winch 2. At the same time, the L-shaped rubber pads 406 and the straight rubber pads 407 can also fill the gap between the L-shaped connector 301 and the mounting box 1, reducing friction and abnormal noise caused by vibration. This achieves all-round shock absorption protection for the mounting box 1 and the winch 2, effectively reducing the impact of vehicle vibration on the vehicle-mounted winch equipment, ensuring the stability of equipment operation, extending the service life of the equipment, and reducing the risk of loosening of mounting components due to vibration.

[0039] Reference Figure 1A sealing cover 5 is rotatably connected to the top rear side of the installation box 1. A rope outlet 6 is opened on the front side of the sealing cover 5. A brush 7 is fixedly connected to the top and bottom of the inner side of the rope outlet 6. Nylon connecting ropes 8 are fixedly connected to the left and right ends of the front side of the installation box 1 and the left and right ends of the front side of the sealing cover 5. A snap fastener 9 is fixedly connected to the adjacent ends of the two nylon connecting ropes 8 on the left side and the adjacent ends of the two nylon connecting ropes 8 on the right side.

[0040] Specifically, the sealing cover 5 on the rear top of the mounting box 1 opens and closes via a rotating connection. When the winch 2 needs maintenance, the sealing cover 5 can be flipped back to expose the winch 2. After use, the sealing cover 5 is flipped forward to close the mounting box 1. The rope outlet 6 on the front side of the sealing cover 5 is the inlet and outlet of the winch 2's steel cable. The brushes 7 fixed to the top and bottom of the inner side of the rope outlet 6 can remove dust and sand adhering to the surface of the steel cable when it enters and exits, preventing these impurities from entering the mounting box 1 and avoiding wear on the components of the winch 2 or affecting its normal operation. Nylon connecting ropes 8 are fixed to the left and right ends of the front side of the mounting box 1 and the left and right ends of the front side of the sealing cover 5. The sealing cover 5 is connected by the snap fasteners 9 at both ends. When the sealing cover 5 is closed, the nylon connecting ropes 8 on the left and right sides are pulled together to fasten the snap fasteners 9, thus firmly connecting the sealing cover 5 to the mounting box 1. This prevents the sealing cover 5 from opening on its own due to vibration during vehicle operation. Through the rotational connection between the sealing cover 5 and the mounting box 1, the cleaning effect of the brush 7 on the steel cable, and the fixing of the sealing cover 5 by the nylon connecting ropes 8 and the snap fasteners 9, the protection effect of the winch 2 inside the mounting box 1 is achieved. This not only prevents external impurities from entering and affecting the performance of the equipment, but also ensures that the sealing cover 5 remains closed when not in use, improving the safety and durability of the vehicle-mounted winch equipment.

[0041] Working principle: During the installation phase, the shock absorption mechanism 4 is first connected to the vehicle frame. Two triangular diagonal braces 401 are fixed to the left and right rear ends of the L-shaped connector 301. The mounting plate 402 at its bottom is fixed to the vehicle frame through the four corners of the top by mounting bolts 404. The anti-loosening pads 405 in the middle prevent the mounting bolts 404 from loosening during vehicle vibration. The sponge pad 403 at the bottom of the mounting plate 402 forms a buffer layer between the bracket and the frame, reducing rigid contact. At the same time, the L-shaped rubber pads 406 at the top left and right ends of the L-shaped connector 301 and the straight rubber pads 407 on the front and rear sides are connected to the frame. Through elastic deformation, the vibration energy during vehicle operation is further absorbed, reducing the impact of vibration on the mounting box 1 and winch 2, thus completing a stable and shock-absorbing connection between the bracket and the vehicle frame. Then, the mounting box 1 is assembled with the L-shaped connector 301. The steel plate 302 on the inner side of the L-shaped connector 301 is aligned with the I-beam groove 303 on the rear side of the mounting box 1. The connecting slider 304 is then inserted into the I-beam groove 303, achieving initial positioning of the L-shaped connector 301 and the mounting box 1. The operator uses a tool to rotate the hexagonal head 3053 at the left end of the locking screw 3051, causing the locking screw 3051 to rotate. The locking screw 3051, which passes through the L-shaped connector 301, is threadedly tightened with the elongated nut 3052, firmly fixing the connecting slider 304 within the I-beam groove 303. This generates a tightening force, ensuring a stable connection between the two. Simultaneously, the longitudinal fixing bolt 306 at the bottom of the L-shaped connector 301 passes through its bottom and is threadedly connected to the bottom of the mounting box 1, further enhancing the connection strength from below. Through these steps, a quick and secure connection is achieved between the mounting box 1 and the L-shaped connector 301, facilitating the subsequent rapid disassembly and maintenance of the winch 2. When the winch 2 is operating, the wear-resistant component 307 comes into play. Two fixing plates 3071 are fixed to the front left and right ends of the inside of the mounting box 1, providing installation support for the two steel drums 3072. The steel cable of the winch 2 is led out from the front of the mounting box 1, contacts the steel drum 3072 and generates friction. The steel drum 3072 rotates under the action of friction, converting the sliding friction between the steel cable and the inner wall of the mounting box 1 into rolling friction, reducing the wear of the steel cable and extending the service life of the steel cable. In terms of daily use and protection, the sealing cover 5 on the rear top of the mounting box 1 is opened and closed by a rotating connection. When the winch 2 needs to be used or repaired, the sealing cover 5 is flipped back and opened.After use, flip the sealing cover 5 forward to close the installation box 1. The rope outlet 6 on the front side of the sealing cover 5 serves as the inlet and outlet of the steel cable. The brushes 7 fixed at the top and bottom of its inner side brush off dust, mud, and other impurities adhering to the surface when the steel cable enters or exits, preventing impurities from entering the installation box 1 and avoiding wear on the winch 2 components or affecting its normal operation. The nylon connecting ropes 8 fixed to the left and right ends of the front side of the installation box 1 and the sealing cover 5 are connected by the snap fasteners 9 at both ends. When the sealing cover 5 is closed, pull the nylon connecting ropes 8 on the left and right sides to make the snap fasteners 9 close, firmly connecting the sealing cover 5 and the installation box 1, preventing the sealing cover 5 from opening on its own during vehicle vibration. During vehicle operation, if encountering bumpy roads, the sponge pad 403, L-shaped rubber pad 406, and straight rubber pad 407 of the shock absorption mechanism 4 work together to absorb and buffer the vibration from the road surface, reducing the vibration transmitted to the installation box. To prevent loosening of the connection or damage to the equipment due to vibration, the quick-release mechanism 3 is operated in reverse when the installation box 1 needs to be disassembled. First, loosen the long nut 3052, manually rotate the locking screw 3051 through the fixing ring 3054 to release the fixing of the connecting slider 304, remove the connecting slider 304 from the I-beam groove 303, and then unscrew the longitudinal fixing bolt 306. The installation box 1 can be quickly disassembled, which is convenient for equipment maintenance and replacement. The quick-release mechanism 3 enables the quick disassembly and assembly of the installation box 1. The shock absorption mechanism 4 ensures the stable operation of the equipment during vehicle travel. The wear-resistant component 307 reduces the wear of the steel cable. The sealing cover 5 and related components protect the winch 2. All components work closely together to ensure that the vehicle-mounted winch mounting bracket meets the requirements for quick installation and disassembly, ensuring the reliable operation of the winch 2 under complex road conditions and improving the safety, durability and ease of maintenance of the equipment.
