Description

Technical Field

[0001] This utility model relates to the field of automobile rescue technology, and in particular to an automobile rescue auxiliary device. Background Technology

[0002] With the increasing frequency of car use, the demand for emergency rescue due to vehicle breakdowns or accidents is growing. Against this backdrop, car rescue devices have become indispensable tools, especially rescue auxiliary devices for lifting and supporting vehicles. Although traditional jacks can solve lifting problems to a certain extent, their structural design and stability have certain shortcomings. In particular, they are prone to instability or insecure support during use. In order to improve rescue efficiency and ensure the safety of operators, it is particularly important to design a car rescue auxiliary device with strong stability and high safety. This device not only needs to have strong support and lifting functions, but also needs to effectively avoid safety hazards such as slippage during the rescue process to ensure the smooth progress of the rescue work.

[0003] Existing rescue auxiliary devices, such as jacks, generally work on the principle of mechanical levers or hydraulic principles. They are operated manually or electrically to generate pressure in the hydraulic device, thereby pushing the support plate up and supporting the vehicle. Their structure usually includes components such as hydraulic cylinders, support columns, and bases. During operation, hydraulic oil is transmitted to the hydraulic cylinder through a pump station, which pushes the piston rod to move, thereby realizing the lifting and lowering of the vehicle.

[0004] The main problem with traditional jacks is the lack of an effective auxiliary support structure, which makes the equipment prone to instability during the support process, especially under high loads. Since the support column of a jack is usually single and controlled by a hydraulic device alone, when the vehicle is in an unstable state or encounters a large lateral force, the jack may tilt or slide, failing to provide continuous support. This structure is less safe during emergency rescue operations, especially when rapid and precise lifting is required, and is prone to accidents. Therefore, a car rescue auxiliary device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a car rescue assistance device, which aims to improve the problem of slippage between the traditional rescue assistance device and the car frame in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a car rescue auxiliary device, comprising a jack frame, a support frame fixedly connected to the top of the jack frame, a fixed frame fixedly connected to the top of the support frame, a hydraulic rod rotatably connected inside the fixed frame, a shaped frame rotatably connected to the output end of the hydraulic rod, a support column rotatably connected to the bottom of the shaped frame, a telescopic rod rotatably connected to the bottom of the support column, a telescopic component provided at one end of the telescopic rod, the telescopic component being used to increase the stability of the jack;

[0007] The telescopic assembly includes a limiting frame and a sliding post. The side wall of the limiting frame is fixedly connected to one end of the telescopic rod. The sliding post is slidably connected inside the limiting frame. The top of the limiting frame is rotatably connected inside the irregular frame. A connecting block is fixedly connected to the top of the jack frame. A sliding assembly is provided inside the connecting block. The sliding assembly is used to drive the clamp to engage.

[0008] As a further description of the above technical solution: the sliding component includes a toothed column one and a toothed column two. The toothed column one is slidably connected inside the connecting block, and the toothed column two is slidably connected inside the connecting block. A hydraulic rod two is fixedly connected to one side of the limiting frame. One end of the hydraulic rod two is fixedly connected to one side of the sliding column one, and a support plate is fixedly connected to the bottom of the sliding column one.

[0009] As a further description of the above technical solution: a motor is fixedly connected inside the connecting block, and a gear is fixedly connected to the output end of the motor, and the gears mesh with the first gear post and the second gear post;

[0010] As a further description of the above technical solution: a crank is fixedly connected to the top of the gear column, and a connecting column is fixedly connected to the top of the crank.

[0011] As a further description of the above technical solution: a support block is fixedly connected to the top of the connecting block, and a notch frame is fixedly connected to the side wall of the support block;

[0012] As a further description of the above technical solution: the connecting column is rotatably connected inside the notch frame, and a sliding column two is rotatably connected to the top of the connecting column;

[0014] As a further description of the above technical solution: a wheel is fixedly connected to the bottom of the jack frame, and a handle is provided on one side of the jack frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the output end of the hydraulic rod drives the irregular frame to rotate, and the rotation of the irregular frame drives the support column to move. Then, the output end of the second hydraulic rod drives the sliding column to move, thereby achieving the effect of opening and retracting the support frame. This solves the problem that traditional jacks do not have an auxiliary support structure, resulting in low stability when supporting cars, and further improves the stability of the device.

[0017] 2. In this utility model, the motor drives the gear to rotate, and the rotation of the gear drives the first gear column and the second gear column to move, which in turn drives the crank, the connecting column and the second sliding column to move, thereby achieving the effect of clamping and lifting the rescue auxiliary device with the car frame. This solves the problem of slippage between the rescue auxiliary device and the car frame in traditional devices and improves the safety of the device. 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 of the embodiments. 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.

[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a car rescue auxiliary device, including a jack frame 1, a support frame 4 fixedly connected to the top of the jack frame 1, a fixed frame 6 fixedly connected to the top of the support frame 4, a hydraulic rod 7 rotatably connected inside the fixed frame 6, the hydraulic rod 7 provides the force required during car rescue, and the force is transmitted and adjusted through a shaped frame 8 and a support column 9, the output end of the hydraulic rod 7 is rotatably connected to the shaped frame 8, the bottom of the shaped frame 8 is rotatably connected to the support column 9, the bottom of the support column 9 is rotatably connected to the side wall of the support frame 4, and the bottom of the support column 9 is rotatably connected to a telescopic rod 10, the telescopic rod 10 enhances the stability of the jack through a telescopic component, especially under heavy load, improving the safety during use, one end of the telescopic rod 10 is provided with a telescopic component, the telescopic component is used to increase the stability of the jack;

[0026] The telescopic assembly includes a limiting frame 11 and a sliding post 12. The cooperation between the limiting frame 11 and the sliding post 12 can effectively limit the displacement of the telescopic rod 10 and ensure the stable operation of the jack. The side wall of the limiting frame 11 is fixedly connected to one end of the telescopic rod 10. The sliding post 12 is slidably connected inside the limiting frame 11. The top of the limiting frame 11 is rotatably connected to the inside of the irregular frame 8. A connecting block 5 is fixedly connected to the top of the jack frame 1. The sliding component inside the connecting block 5 enables the clamp to clamp precisely, improving the convenience and accuracy of operation. The sliding component is provided inside the connecting block 5 and is used to drive the clamp to clamp.

[0027] Specifically, when using the car rescue auxiliary device, the jack frame 1 must first be moved under the damaged car to ensure the device is in the correct position. Next, the hydraulic rod 7 is activated, and the output end of the hydraulic rod 7 pushes the irregular frame 8 to move. As the irregular frame 8 moves, the support column 9 also shifts. The movement of the support column 9 further drives the telescopic rod 10 to make corresponding adjustments. Under the pushing action of the hydraulic rod 7, the support column 9 will gradually adjust to a position perpendicular to the ground, providing a stable foundation for subsequent support. At this time, the limit frame 11 is activated, and the output end of the limit frame 11 pushes the sliding column 12 to slide downward. As the sliding column 12 slides down, it drives the support plate 13 below to gradually move towards the ground until the support plate 13 is in close contact with the ground, forming a stable support surface. This process ensures that the support plate 13 can evenly distribute the load and effectively avoids the offset or unevenness of the support point, greatly improving the stability of the rescue auxiliary device during vehicle support and ensuring the safety and reliability of the entire rescue operation.

[0028] Reference Figure 3 and Figure 4The sliding assembly consists of a toothed column 15 and a toothed column 26, which are slidably connected inside the connecting block 5 to ensure smooth movement of the assembly. A motor 20 is fixedly connected inside the connecting block 5. The motor 20 drives a gear 24 through its output end. The gear 24 meshes with the toothed column 15 and the toothed column 26, causing the toothed column to slide and realize mechanical transmission. A hydraulic rod 24 is fixedly connected to one side of the connecting block 5. The hydraulic rod 24 is connected to the sliding column 12 through one end, and the hydraulic rod provides additional power support. A support plate 13 is fixedly connected to the bottom of sliding column 12, providing stable support for sliding column 12 and ensuring balance during movement. A crank 17 is fixedly connected to the top of toothed column 15, and the crank 17 is connected to connecting column 18 through its top. Connecting column 18 is rotatably connected inside notch frame 19. Sliding column 21 is rotatably connected to the top of connecting column 18, and sliding column 21 is slidably connected inside support block 22. A clamping plate 23 is fixedly connected to one end of sliding column 21 for clamping or positioning objects to ensure accuracy during operation. Wheels 2 are fixedly connected to the bottom of jack frame 1 for convenient movement and position adjustment of components. A handle 3 is provided on one side of jack frame 1 for operating and controlling the direction and position of the entire device.

[0029] Specifically, when the rescue auxiliary equipment is accurately placed at the rescue location, the lifting mechanism of the jack frame 1 begins to move upward by turning the handle 3, gradually raising the equipment to a suitable height. When the surface of the connecting block 5 contacts the car frame, the motor 20 is started. The output end of the motor 20 begins to drive the gear 24 to rotate, and also pushes the second gear 16 to slide inside the connecting block 5. The movement of the first gear 15 then drives the crank 17 to move along the designated path. The movement of the crank 17 is transmitted to the notch frame 19 through the connecting column 18, causing the angle of the notch frame 19 to change. As the angle of the notch frame 19 is adjusted, the second sliding column 21 begins to move towards the middle position of the connecting block 5. The sliding of the second sliding column 21 inside the support block 22 makes its connection with the clamping plate 23 tighter, and finally pushes the clamping plate 23 to move towards the car frame. This action achieves the locking effect between the rescue auxiliary device and the car. The whole process is precise and smooth. From the lifting of the equipment to the locking, it ensures that the equipment can provide sufficient support and stability during the rescue operation, thereby ensuring the smooth progress of the rescue work.

[0030] Working Principle: When using the car rescue auxiliary device, first move the jack frame 1 under the damaged car, then activate hydraulic rod 7. The output end of hydraulic rod 7 pushes the irregular frame 8 to move. During the movement of irregular frame 8, the support column 9 moves. When the support column 9 moves, it drives the telescopic rod 10 to move. Under the action of hydraulic rod 7, the support column 9 becomes perpendicular to the ground. At this time, activate limit frame 11. The output end of limit frame 11 drives sliding column 12 to slide downward. When sliding column 12 slides downward, it drives the support plate 13 below to move towards the ground until the support plate 13 is in close contact with the ground, thereby further improving the stability of the rescue auxiliary device. When the rescue auxiliary device is placed in the rescue position... When the jack frame 1 is in place, the lifting mechanism of the jack frame 1 is moved upward by turning the handle 3. When the surface of the connecting block 5 contacts the car frame, the motor 20 is started. The output end of the motor 20 drives the gear 24 to rotate. The rotation of the gear 24 drives the first gear 15 and the second gear 16 to slide inside the connecting block 5. When the first gear 15 moves, it drives the crank 17 to move. The movement of the crank 17 causes the connecting column 18 to change its angle inside the notch frame 19. When the angle of the notch frame 19 changes, it pushes the second sliding column 21 to move towards the middle position of the connecting block 5. Through the sliding of the second sliding column 21 inside the support block 22, the second sliding column 21 pushes the clamping plate 23 to move, thereby achieving the degree of clamping between the rescue auxiliary device and the car.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
