Abstract
Description
Technical Field
[0001] This utility model relates to the field of obstacle clearing devices, and in particular to a vehicle obstacle clearing device. Background Technology
[0002] With the surge in traffic flow and increased demand for vehicles, the need for road accident and breakdown vehicle removal has grown significantly. Traditional tow trucks rely on manual judgment of towing points, which is prone to secondary damage to vehicles due to improper operation, resulting in low efficiency. Furthermore, the need for manual securing devices (such as steel cables and hooks) can lead to loosening in complex road conditions, posing safety hazards and compromising safety. In existing technologies, some tow trucks employ folding booms and modular clamps. The folding boom is raised and lowered, and the position of the modular clamps is adjusted, then the clamps grip the tires of the disabled vehicle to achieve towing. However, existing folding booms consist of multiple boom segments connected together, and multiple cylinders drive the movement of each segment to achieve multi-angle, multi-range movement of the modular clamps. This not only results in a complex structure but also requires multiple cylinders to operate in coordination, leading to high power costs. Utility Model Content
[0003] Based on the above, the purpose of this utility model is to provide a vehicle obstacle clearing device with low power source cost and good structural compactness.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A vehicle obstacle clearing device, comprising:
[0006] Chassis;
[0007] A clearing mechanism is mounted on the chassis. The clearing mechanism includes a robotic arm, a telescopic drive, and a support arm assembly. The robotic arm includes a main arm rotatably mounted on the chassis and a boom movably connected to the main arm along its length. The support arm assembly is mounted on the end of the boom opposite to the main arm and is used to grip or release the tires of the disabled vehicle. One end of the telescopic drive is rotatably connected to the chassis, and the other end is rotatably connected to the boom. As the telescopic drive extends and retracts, it drives the boom to move along the main arm and simultaneously drives the main arm to rotate.
[0008] As a preferred embodiment of a vehicle obstacle clearing device, the telescopic drive component includes a telescopic cylinder, one end of the cylinder body of the telescopic cylinder is hinged to the chassis, and one end of the telescopic rod of the telescopic cylinder is hinged to the boom.
[0009] As a preferred embodiment of a vehicle obstacle clearing device, the boom includes a first boom segment and a second boom segment arranged at an angle. The first boom segment is movably connected to the main boom along the length direction of the main boom, and the support arm assembly is installed on the end of the second boom segment opposite to the first boom segment.
[0010] As a preferred embodiment of a vehicle obstacle clearing device, the angled opening formed between the first arm segment and the second arm segment faces the chassis.
[0011] As a preferred embodiment of a vehicle clearing device, the boom assembly includes a support arm and two clamping members. The support arm is disposed at one end of the boom away from the main boom, and the two clamping members are spaced apart on the support arm along a first direction. Each clamping member can clamp or release one tire of the disabled vehicle. The first direction is consistent with the width direction of the chassis.
[0012] As a preferred embodiment of a vehicle clearing device, the clamping component includes a fixed arm and a movable arm. The fixed arm is fixed to the support arm, and the movable arm is movably connected to the fixed arm. A clamping space is formed between the fixed arm and the movable arm. As the movable arm moves, the clamping space increases or decreases to clamp or release the tires of the disabled vehicle.
[0013] As a preferred embodiment of a vehicle obstacle clearing device, the movable arm includes a vertically arranged first segment and a second segment. The end of the first segment facing away from the second segment is rotatably connected to the fixed arm. The movable arm has a loosened position and a clamped position relative to the fixed arm. When the movable arm is in the clamped position, the second segment is parallel to the fixed arm at a distance, and the clamping space is U-shaped. When the movable arm is in the loosened position, the first segment and the fixed arm form an obtuse angle, the second segment is away from the fixed arm, and the clamping space becomes larger.
[0014] As a preferred embodiment of a vehicle obstacle clearing device, the support arm assembly further includes two clamping drive members, which are disposed on the support arm, and each clamping drive member is used to drive one of the first segments to rotate.
[0015] As a preferred embodiment of a vehicle obstacle clearing device, the clamping drive component includes a linear drive source. The first segment is rotatably connected to the fixed arm via a transmission plate. The transmission plate is rotatably connected to the fixed arm via a rotating shaft and has a first end and a second end distributed on both sides of the rotating shaft.
[0016] One end of the linear drive source is mounted on the support arm, and the other end is hinged to the first end. The drive end of the linear drive source can move along the first direction. The first segment is fixedly connected to the second end. As the drive end of the linear drive source moves, it drives the transmission plate to rotate, thereby driving the movable arm to switch between the loosened position and the clamped position.
[0017] As a preferred embodiment of a vehicle obstacle clearing device, one side of the chassis is provided with an obstacle clearance notch, which allows the boom to engage with the obstacle clearance notch as the main boom rotates and the boom moves.
[0018] The beneficial effects of this utility model are as follows:
[0019] This utility model provides a vehicle clearing device. The main arm is rotated and the boom is moved on the main arm. Driven by the telescopic drive, the main arm can rotate and the boom can move, realizing the lifting and lowering and forward and backward movement of the boom assembly, so that the boom assembly can be smoothly aligned with the tires of the disabled vehicle. Compared with the prior art, which uses multiple drive sources to drive the movement of multiple boom sections, this vehicle clearing device has a lower power source cost, simpler structure, better compactness, and is easier to operate.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it.

[0034] like Figures 1 to 7 As shown, this embodiment provides a vehicle clearing device, which includes a chassis 1 and a clearing mechanism. The clearing mechanism is mounted on the chassis 1 and includes a mechanical arm 2, a telescopic drive 3, and a support arm assembly 4. The mechanical arm 2 includes a main arm 21 rotatably mounted on the chassis 1 and a boom 22 movably connected to the main arm 21 along its length. The support arm assembly 4 is mounted on one end of the boom 22 away from the main arm 21 and is used to grip or release the tire of the disabled vehicle. One end of the telescopic drive 3 is rotatably connected to the chassis 1, and the other end is rotatably connected to the boom 22. As the telescopic drive 3 extends and retracts, it drives the boom 22 to move along the main arm 21, and simultaneously drives the main arm 21 to rotate. By rotating the main arm 21 and moving the boom 22 on it, the telescopic drive 3 can drive the main arm 21 to rotate and the boom 22 to move, thereby realizing the lifting and lowering and forward and backward movement of the support arm assembly 4, so that the support arm assembly 4 can be smoothly aligned with the tire of the disabled vehicle (e.g., the tire of the disabled vehicle). Figures 1 to 4 As shown, the telescopic drive 3 drives the robotic arm 2 to different positions in different states and the telescopic length of the boom 22 relative to the main boom 21 is different. Compared with the existing technology that uses multiple drive sources to drive the movement of multiple boom sections, the power source of this vehicle obstacle clearing device has lower cost, simpler structure and easier operation.
[0035] It should be noted that the vehicle clearing device can be mounted on a vehicle, such as a pickup truck, to form a clearing vehicle. After the tow arm assembly 4 grips the front or rear tires of the disabled vehicle, the clearing vehicle can easily tow away the disabled vehicle.
[0036] In this embodiment, the telescopic drive component 3 includes a telescopic cylinder. One end of the cylinder body is hinged to the chassis 1, and one end of the telescopic rod is hinged to the boom 22. By axially moving the telescopic rod within the cylinder body, i.e., extending or shortening the overall length of the telescopic cylinder, a pushing or pulling force is applied to the boom 22. The boom 22 moves along the main boom 21 under force, while the main boom 21 rotates under force. The telescopic cylinder also provides support for the robotic arm 2. Of course, in other embodiments, the telescopic drive component 3 can also have other structures, as long as it can achieve the telescopic function.
[0037] Specifically, the boom 22 includes a first boom segment 221 and a second boom segment 222 arranged at an angle. The first boom segment 221 is movably connected to the main boom 21 along its length. The support arm assembly 4 is mounted on the end of the second boom segment 222 opposite to the first boom segment 221. The angle formed between the first boom segment 221 and the second boom segment 222 faces the chassis 1, allowing the support arm assembly 4 to be easily moved to a lower position to align with the tires. For example, the first boom segment 221 and the second boom segment 222 form an obtuse angle.
[0038] Preferably, the first arm segment 221 is slidably sleeved on the main arm 21, resulting in a high degree of structural compactness and a simple and aesthetically pleasing external structure. A slider or a sliding rail and slider cooperation structure can be provided between the first arm segment 221 and the main arm 21 to improve the smoothness of sliding between them.
[0039] Preferably, one side of the chassis 1 is provided with a clearance notch, which allows the boom 22 to engage with the main boom 21 as it rotates and the boom 22 moves. This expands the range of motion of the robotic arm 2, allowing it to descend to the lowest possible height so that the support arm assembly 4 can be smoothly aligned with the lower tire.
[0040] Furthermore, such as Figures 5 to 7 As shown, the support arm assembly 4 includes a support arm 41 and two clamping members 42. The support arm 41 is located at the end of the boom 22 opposite to the main boom 21. The two clamping members 42 are spaced apart on the support arm 41 along a first direction. Each clamping member 42 can clamp or release one tire of the disabled vehicle. The first direction is consistent with the width direction of the chassis 1. The telescopic drive member 3 drives the mechanical arm 2 to move, that is, drives the support arm assembly 4 to move to the tire of the disabled vehicle. By clamping one tire with each of the two clamping members 42, the disabled vehicle can be towed away.
[0041] In this embodiment, the support arm 41 has a T-shaped structure, and the crossbar of the support arm 41 extends along the first direction to facilitate the setting of the two clamping members 42.
[0042] Specifically, the clamping member 42 includes a fixed arm 421 and a movable arm 422. The fixed arm 421 is fixed to the support arm 41, and the movable arm 422 is movably connected to the fixed arm 421. A clamping space is formed between the fixed arm 421 and the movable arm 422. As the movable arm 422 moves, the clamping space increases or decreases to clamp or release the tires of the faulty vehicle. When operation is required, the movable arm 422 is opened to maximize the clamping space. The robotic arm 2 moves the support arm assembly 4 until the two tires enter the two clamping spaces respectively. Then, the movable arm 422 is closed to reduce the clamping space until the fixed arm 421 and the movable arm 422 clamp the tires. The fixed arrangement of the fixed arm 421 facilitates tire alignment. Of course, in other embodiments, the clamping member 42 can also be other structures, such as a claw structure, where the two clamping arms can move closer or further apart.
[0043] More specifically, the movable arm 422 includes a first segment 4221 and a second segment 4222 arranged vertically. The end of the first segment 4221 facing away from the second segment 4222 is rotatably connected to the fixed arm 421. The movable arm 422 has an open position and a closed position relative to the fixed arm 421. When the movable arm 422 is in the closed position, the second segment 4222 is parallel to the fixed arm 421 at a distance, and the clamping space is U-shaped. When the movable arm 422 is in the open position, the first segment 4221 forms an obtuse angle with the fixed arm 421, and the second segment 4222 moves away from the fixed arm 421, increasing the clamping space. That is, as the first segment 4221 rotates, the movable arm 422 opens or closes relative to the fixed arm 421. Of course, in other embodiments, the connection between the movable arm 422 and the fixed arm 421 can also take other forms. For example, the first segment 4221 is vertically fixed to the fixed arm 421, and the second segment 4222 moves along the length direction of the first segment 4221 and is connected to the first segment 4221, and is perpendicular to the first segment 4221, while being arranged opposite to the fixed arm 421. The clamping space can be increased or decreased by moving the second segment 4222.
[0044] Preferably, when the two clamping spaces are U-shaped, the two U-shaped clamping spaces are opposite to each other, that is, both movable arms 422 rotate inward, reducing the space occupied during use.
[0045] Furthermore, the support arm assembly 4 also includes two clamping drive members 43, which are mounted on the support arm 41. Each clamping drive member 43 is used to drive a first segment 4221 to rotate. By driving the first segment 4221 to rotate through the clamping drive member 43, automatic clamping and releasing are achieved.
[0046] In this embodiment, the clamping drive component 43 includes a linear drive source. A first segment 4221 is rotatably connected to a fixed arm 421 via a transmission plate 44. The transmission plate 44 is rotatably connected to the fixed arm 421 via a rotating shaft and has a first end and a second end distributed on both sides of the rotating shaft. One end of the linear drive source is mounted on a support arm 41, and the other end is hinged to the first end. The driving end of the linear drive source can move along a first direction. The first segment 4221 is fixedly connected to the second end. As the driving end of the linear drive source moves, it drives the transmission plate 44 to rotate, thereby causing the movable arm 422 to switch between a loosened position and a clamped position. That is, the transmission plate 44 acts as a "lever" structure, converting the linear movement of the linear drive source into the rotation of the first segment 4221. The linear drive source is a telescopic hydraulic cylinder, which has good structural strength and load-bearing capacity. Of course, in other embodiments, the clamping drive component 43 can also be other structures, such as a drive motor.
[0047] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
