Description

Technical Field

[0001] This utility model relates to the field of automotive repair hydraulic equipment technology, specifically a portable automotive repair hydraulic equipment. Background Technology

[0002] Automotive repair hydraulic equipment is a general term for various tools and devices used for automobile repair and maintenance based on the principle of hydraulic transmission. It includes jacks, lifts, hydraulic wrenches, hydraulic pullers, etc. Mobile automotive repair hydraulic equipment is a type of equipment that is improved from conventional hydraulic equipment by adding rollers, portable handles or adopting a lightweight design. Its core function is to break through the limitations of fixed work sites and can be flexibly moved to the location of the broken-down vehicle to quickly carry out operations such as chassis repair, tire removal and installation, and parts disassembly and installation. It not only saves the tedious steps of moving vehicles, but also adapts to special scenarios such as rescue sites and outdoor emergency repairs, greatly improving the flexibility and efficiency of automotive repair operations.

[0003] For example, a movable automotive repair hydraulic device disclosed in Chinese patent literature (publication number: CN216046210U) facilitates movement through a moving mechanism, machine body, hydraulic gauge, screw, inspection door, first hinge, casters, threaded shaft, fixed cover, and second hinge. This effectively enhances the simplicity of the device, making it convenient for operators to operate, improving its ease of use, meeting application needs, facilitating internal maintenance, extending its lifespan, effectively improving work efficiency, and enhancing its practicality. In use, the hydraulic gauge is first fixed to the upper side of the device by screwing it in place, allowing for observation of its internal operation. The device is then pushed, and the casters are adjusted to the appropriate working position via the threaded shaft. The fixed cover is then rotated downwards and fixed by the second hinge. After use, the inspection door is pulled to one side, and opened by the first hinge, allowing for internal maintenance and repair.

[0004] However, the ease of movement of this equipment relies entirely on four casters that always bear the full weight of the equipment. Even with the fixed cover that flips down to lock it, this is essentially just a brake or an increase in friction to prevent the wheels from rolling freely. During high-load hydraulic operations, the huge reaction force and vibration will be transmitted through the elastic tires and shock-absorbing structure of the wheels, which may cause the equipment to settle, shake or slip slightly. Such instability is unacceptable in high-precision or high-safety automotive repair operations and poses a safety hazard. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile automotive repair hydraulic device, comprising: a base plate, a hydraulic device body fixedly connected to the top middle of the base plate, a cylinder fixedly connected to the other top end of the base plate, the movable end of the cylinder penetrating the base plate and extending to the bottom of the base plate, a support plate fixedly connected to the movable end of the cylinder, a support block fixedly connected to one bottom end of the base plate, and a drive steering mechanism provided on one side edge of the top of the base plate.

The first gear is symmetrically fixedly connected to the other two outer sides of the rotating rod, and the bearing seat is fixedly connected to one side of the base plate.

[0009] As a further embodiment of this utility model: the drive steering mechanism further includes a rotating shaft, a connecting steering rod, and a second gear. Two sets of rotating shafts are provided, each rotatably connected to the interior of one of the two sets of bearing seats. The connecting steering rod is fixed to the inner ring of the two sets of rotating shafts, and both ends of the connecting steering rod pass through the two sets of rotating shafts.

The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 5 In this embodiment of the utility model, a mobile automotive repair hydraulic device includes: a base plate 1, a hydraulic device body 2 fixedly connected to the top middle of the base plate 1, a cylinder 3 fixedly connected to the other top end of the base plate 1, the movable end of the cylinder 3 passing through the base plate 1 and extending to the bottom of the base plate 1, a support plate 4 fixedly connected to the movable end of the cylinder 3, a support block 5 fixedly connected to one bottom end of the base plate 1, and a drive steering mechanism 6 provided on one side edge of the top of the base plate 1. There are four sets of cylinders 3 and four sets of support plates 4. The movable end of each set of cylinders 3 is connected to every two sets of support plates 4. There are two sets of drive steering mechanisms 6, which are symmetrically arranged on the top two sides of the base plate 1. There are multiple sets of support piers 5, and the interior of each set of support piers 5 is hollow. When the equipment is moved to the working position, the operator can control the cylinders 3 to work. The movable end of the cylinder 3 extends downward and pushes the support plate 4 downward. The support plate 4 continues to move downward until it touches the ground, so that the roller component is away from the ground. Then, the movable end of the cylinder 3 is retracted to keep the support plate 4 and the support pier 5 at the same level. During this process, the operator only needs to briefly ensure the stability of the base plate 1. Then, the base plate 1 is lowered, so that the support plate 4 and the support pier 5 together support the whole body firmly on the ground. At this time, the weight of the hydraulic equipment body 2 is mainly borne by the support plate 4 and the support pier 5, which can ensure the absolute stability of the hydraulic equipment body 2 during operation and prevent the whole body from shifting due to the huge reaction force generated by hydraulic operation.

[0019] Reference Figures 1 to 4 A sealing ring groove 7 is provided at the bottom of the base plate 1 and at the part through which the moving end of the cylinder 3 passes. A sealing ring gasket 8 is symmetrically fixedly connected to the top of the support plate 4. The sealing ring groove 7 and the sealing ring gasket 8 are compatible. After the operation is completed, when the moving end of the cylinder 3 is retracted and the support plate 4 is moved upward, the sealing ring gasket 8 at the top of the support plate 4 is tightly pressed into the sealing ring groove 7 at the bottom of the base plate 1 to form an effective seal and prevent dust and moisture from affecting the cylinder 3 when it is not in use. Push rods 9 are symmetrically fixedly connected to both sides of the base plate 1. Anti-slip sleeves 10 are tightly fitted on the outer side of the handle above the push rods 9. When the equipment is in use, the operator holds the anti-slip sleeves 10 on the push rods 9 to push or stabilize the whole equipment.

[0020] Reference Figure 1 and Figure 5 The drive steering mechanism 6 includes a support frame 61, a protective chamber 62, and a motor 63. The support frame 61 is fixedly connected to the top of the other end of the base plate 1, the protective chamber 62 is fixedly connected to the upper end of the support frame 61, and the output end of the motor 63 extends through to the lower part of the protective chamber 62. The motor 63 is fixedly connected inside the protective chamber 62. The active bevel gear 64, the base frame 65, and the rotating rod 66 are fixedly connected to the output end of the motor 63, the base frame 65 is fixedly connected to the top edge of the base plate 1, and the rotating rod 66 is rotatably connected to the upper inner side of the base frame 65. Driven bevel gear 67, gear 68, and bearing seat 69. Driven bevel gear 67 is fixedly connected to the middle of the outer side of rotating rod 66 and meshes with driving bevel gear 64. Gear 68 is symmetrically fixedly connected to the other two ends of the outer side of rotating rod 66. Bearing seat 69 is fixedly connected to one side of base plate 1. By starting the motor 63 inside the protective chamber 62 on the support frame 61, the motor 63 drives the driving bevel gear 64 to rotate. The driving bevel gear 64 meshes with driven bevel gear 67, driving rotating rod 66 to rotate on base frame 65. Gear 68, which is fixed at both ends of the outer side of rotating rod 66, rotates accordingly and drives gear 612, which meshes with it, to rotate.

[0021] Reference Figure 1 and Figure 5 The drive steering mechanism 6 also includes a rotating shaft 610, a connecting steering rod 611, and a second gear 612. There are two sets of rotating shafts 610, which are rotatably connected to the inside of two sets of bearing seats 69. The connecting steering rod 611 is fixed to the inner ring of the two sets of rotating shafts 610, and both ends of the connecting steering rod 611 pass through the two sets of rotating shafts 610. The second gear 612 is symmetrically fixed to the outer ends of the connecting steering rod 611, and the second gear 612 meshes with the first gear 68. The connecting plate 613, the damping shock absorber 614, and the universal brake wheel 615 are fixedly connected to the lower end of the connecting steering rod 611, the damping shock absorber 614 is fixedly connected to the bottom of the connecting plate 613, and the universal brake wheel 615 is fixedly connected to the bottom of the damping shock absorber 614. Multiple sets of connecting plates 613, damping shock absorbers 614, and universal brake wheels 615 are provided. Multiple sets of connecting plates 613 are symmetrically arranged below the connecting steering rod 611. Gear 612 is fixed on the connecting steering rod 611, thereby driving the connecting steering rod 611 to rotate around its axis. The rotational motion of the connecting steering rod 611 is transmitted to the damping shock absorber 614 through the connecting plate 613 at its lower end, and finally drives the universal brake wheel 615 to rotate inward and upward, so that the universal brake wheel 615 is stored from the working posture to a non-interference position above the base plate 1, avoiding space obstruction and safety hazards, thereby completing the state switch after the equipment is in place.

[0022] The working principle of this utility model is as follows: In use, the operator holds the anti-slip sleeve 10 on the push rod 9 and moves the entire unit using the universal brake wheel 615. Once the equipment is in the working position, the operator can control the cylinder 3 to operate. The movable end of the cylinder 3 extends downward, pushing the support plate 4 downward. The support plate 4 continues to move downward until it contacts the ground, causing the universal brake wheel 615 to move away from the ground. This activates the motor 63 inside the protective compartment 62 on the support frame 61 in the drive steering mechanism 6. The motor 63 drives the active bevel gear 64 to rotate. The active bevel gear 64 meshes with the driven bevel gear 67, driving the rotating rod 66 to rotate on the base frame 65. The gear 68 fixed at both ends of the outer side of the rotating rod 66 rotates accordingly, driving the gear 612 meshing with it to rotate. The gear 612 is fixed on the connecting steering rod 611, thereby driving the connecting steering rod 611 to rotate around its axis. The rotational movement of the connecting steering rod 611 is transmitted through the connecting plate 613 at its lower end. The force is transmitted to the damping shock absorber 614, which ultimately drives the universal brake wheel 615 to rotate inward and upward. This allows the universal brake wheel 615 to be stored in a non-interference position above the base plate 1 from its working posture, avoiding potential space obstruction and safety hazards caused by the wheel when lifting vehicles or operating large components. Then, the moving end of the cylinder 3 is used to retract the support plate 4 and the support block 5 to keep them at the same level. During this process, the operator only needs to briefly ensure the stability of the base plate 1 before lowering the base plate 1. This allows the support plate 4 and the support block 5 to jointly and stably support the whole on the ground. At this time, the weight of the hydraulic equipment body 2 is mainly borne by the support plate 4 and the support block 5, which can ensure the absolute stability of the hydraulic equipment body 2 during operation and prevent the whole from shifting due to the huge reaction force generated by hydraulic operation. The core function of the damping shock absorber 614 is to absorb road bumps and ensure the overall stability when the universal brake wheel 615 moves. After the operation is completed, the entire unit can be restored to a movable state by directional operation. When the movable end of the cylinder 3 is retracted and the support plate 4 is moved upward, the sealing ring gasket 8 on the top of the support plate 4 is tightly pressed into the sealing ring groove 7 at the bottom of the base plate 1, forming an effective seal to prevent dust and moisture from affecting the cylinder 3 when it is not in use.

[0023] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
