Description

Mobile device for identifying accident vehicles

Technical Field

The utility model relates to the technical field of road rescue, in particular to a mobile device for identifying accident vehicles.

Background

Identifying an accident vehicle may help determine the responsibility and cause of the accident when the vehicle has an accident. Accident vehicle identification can determine the loss range caused by accidents, and is helpful for vehicle owners and insurance companies to calculate claims and reimbursements. The identification can evaluate the damage degree of the accident vehicle, help the vehicle owner decide whether to repair or not, and what maintenance work needs to be performed.

After an accident in a vehicle, conventional techniques typically use a series of tools and methods to lift and carry the accident vehicle, such as a trailer, is one of the most common methods to lift and carry the accident vehicle. Special trailers are typically removed from the accident scene by towing or lifting the front or rear of the accident vehicle. This is generally applicable to situations where the vehicle is less damaged; also for example, for heavier accident vehicles, particularly those involving large vehicles or trucks, a crane may be used to lift and carry the damaged vehicle onto a trailer or other conveyance. Also for example, flatbed trailers, which are vehicles specifically designed for transporting damaged vehicles. These trailers have a flat cargo area that allows the accident vehicle to be smoothly loaded and transported to a repair shop or other destination.

However, as long as the inventor works and researches, the above lifting and carrying modes in the conventional technology have the following technical problems to be solved:

(1) Restriction fixation: conventional techniques typically use ropes, chains, etc. to secure accident vehicles, but this approach may be limited in location and angle, and it is difficult to adapt to different vehicle shapes and sizes, which may result in weak securement and even additional damage during transportation.

(2) Risk of surface damage: conventional trailer and crane technologies may cause additional damage to the accident vehicle surface, such as scratches, extrusions, and the like. This may affect the accuracy of the identification of the accident vehicle and also increase the maintenance cost.

(3) Not adapted to special cases: conventional techniques may be difficult to address the needs of accident vehicle identification in small spaces or complex terrain environments, are not flexible enough to operate, and may not meet the needs in special situations.

For this purpose, a mobile device for accident vehicle authentication is proposed.

Preferably, the driving synchronization of the hydraulic elements is controlled by a controller.

Specific: the presence of the frame 1 plays a supporting and load-bearing role in this embodiment. The hydraulic arm mechanism 2 is loaded onto the frame 1, which enables the whole device to operate an accident vehicle with support of the frame 1. The frame 1 should be sufficiently strong and stable in design and construction to withstand the movements and loads of the hydraulic arm mechanism 2 and the hydraulic jaw mechanism 3.

In the scheme, the method comprises the following steps: the hydraulic arm mechanism 2 is configured in a strip-shaped structure, and is composed of a first arm 201, a second arm 202, and a telescopic arm 203. The telescopic arm 203 is formed by sequentially nesting and sliding a plurality of arm frames, and the end surfaces of the first arm body 201, the second arm body 202 and the telescopic arm 203 are sequentially connected through hinge joints. This embodiment further comprises three first hydraulic cylinders 204, the cylinders and piston rods of which are connected by hinges to the first and second arms 201, 202 and 203, respectively, the outermost arm rest and the innermost arm rest of the telescopic arm 203.

Specific: the design of the hydraulic arm mechanism 2 and the configuration of the hydraulic cylinder 204 provide the hydraulic arm with telescopic, adjustable characteristics. The articulated connection of the first arm 201, the second arm 202 and the telescopic arm 203 allows movement of these parts in multiple directions, enabling flexibility and controllability of the hydraulic arm. The design of the plurality of nested arms of the telescopic arm 203 enables the length of the hydraulic arm to be adjusted as required, so as to adapt to different operation scenes.

It will be appreciated that in this embodiment: the hydraulic arm mechanism 2 of this embodiment provides a variety of operational capabilities during the identification of an accident vehicle. By adjusting the piston rod of the hydraulic cylinder 204, the different parts of the hydraulic arm can be telescopic, height-adjustable and feed-adjustable, thereby achieving accurate positioning and fixing of the accident vehicle. The nested slip fit telescoping arms 203 allow for telescoping adjustment as needed depending on the size and shape of the accident vehicle to better accommodate the immobilization requirements. The hydraulic arm mechanism 2 in this embodiment provides more customizable and adaptable operation of the mobile device through its structural flexibility and adjustability. The method is favorable for better processing accident vehicles of different types and shapes in practical application, and improves the accuracy and efficiency of accident vehicle identification.

In some embodiments of the present application, please refer to fig. 3-5 in combination: the hydraulic claw mechanism 3 comprises a rack 301, and the rack 301 is fixedly arranged on the arm support at the innermost part of the telescopic arm 203; four jaws 302 are annularly and array-hinged to the outer surface of the stand 301, and four linear modules for outputting a first linear degree of freedom are annularly and array-mounted to the outer surface of the stand 301 and used for driving the jaws 302 to perform angle adjustment.

In the scheme, the method comprises the following steps: the hydraulic claw mechanism 3 realizes the accurate fixation of the accident vehicle surface through the coordination work of the angle-adjustable clamp claw and the linear module. This helps to ensure firm grip of the accident vehicle under different conditions, thereby improving the accuracy of the authentication process and the ease of operation.

Specific: the hydraulic claw mechanism 3 is designed to realize the angle adjustment of the claw 302 mainly through the frame 301 and the linear module. The frame 301 is mounted on the innermost arm support of the telescopic arm 203, and the annular array connection of its outer surface enables four jaws 302 to be secured to the frame by means of hinges. With the output of the linear module, the jaws 302 can be adjusted in precise angles to accommodate different accident vehicle surface shapes and features.

It will be appreciated that in this embodiment: the hydraulic jaw mechanism 3 allows the angle of the jaws to be adjusted during accident vehicle qualification to accommodate vehicle surfaces of different shapes and locations. The use of a linear die set provides high precision control so that the jaws 302 can be adjusted in angle precisely, ensuring a firm fixation. The annular array of jaws 302 allows them to be flexibly moved and fixed on the frame 301 for adjustment as the case may be.

In some embodiments of the present application, please refer to fig. 3-5 in combination: the linear module is preferably a second hydraulic cylinder 303; the cylinder body and the piston rod of the second hydraulic cylinder 303 are hinged to the outer surface of the frame 301 and the outer surface of the jaw 302, respectively.

In the scheme, the method comprises the following steps: this design not only provides better handling control, but also ensures a secure securement of the accident vehicle during operation. The hydraulically driven angular adjustment allows the operator to easily fine tune the jaws to ensure a fixed tightness and stability. This is critical to achieving accurate accident vehicle identification results.

Specific: the use of the second hydraulic cylinder 303 as a linear module in the hydraulic jaw mechanism 3 is designed such that the angular adjustment of the hydraulic jaw can be achieved by hydraulic power. The cylinder is fixed to the outer surface of the frame 301 and the piston rod is hinged to the outer surface of the jaw 302, whereby the telescopic movement of the piston rod results in angular adjustment of the jaw 302 by hydraulic actuation.

It will be appreciated that in this embodiment: by applying the second hydraulic cylinder 303 as a linear module to the hydraulic jaw mechanism 3, a controllable adjustment of the jaw angle is achieved. The hydraulic power makes the angle adjustment more convenient and accurate during operation. By adjusting parameters of the hydraulic system, the angle of the clamp claw can be quickly and accurately adjusted so as to adapt to the characteristics of different vehicle surfaces.

In some embodiments of the present application, please refer to fig. 3-5 in combination: the buffer mechanism 4 comprises two opposite frame bodies 401, six oil pressure buffer cylinders 402 for outputting a second linear degree of freedom are uniformly arranged between the two frame bodies 401 in a ring array mode, and the cylinder bodies and piston rods of the oil pressure buffer cylinders 402 are respectively and universally hinged to the opposite surfaces of the two frame bodies 401 through universal joint couplings 403; one frame 401 is fixedly arranged on the clamp claw 302, and a damping buffer pad 404 is arranged on the other frame 401.

In the scheme, the method comprises the following steps: the buffer mechanism 4 is composed of two mutually opposed frame bodies 401. Six hydraulic buffer cylinders 402 are uniformly installed in an annular array between the two frame bodies 401 for outputting the second degree of linear freedom. The cylinder body and the piston rod of each hydraulic buffer cylinder 402 are all articulated in a universal manner by a universal joint coupling, and are connected to opposite sides of the two frame bodies 401.

Specific: the damping mechanism 4 is designed to provide flexibility and damping capability in the operation of the hydraulic jaw mechanism 3. The presence of the hydraulic buffer cylinder 402 provides an adjustment capability of the second linear degree of freedom by the movement of its piston rod to accommodate different positions and stress conditions. The universal joint coupling enables articulation of the damper cylinder 403 in multiple directions, thereby enabling more flexible movement.

It will be appreciated that in this embodiment: the design of the cushioning mechanism 4 plays a key role in carrying, securing and lifting the accident vehicle. Adjustment of the hydraulic buffer cylinder 402 allows the buffer mechanism 4 to automatically perform adaptive telescoping according to the force applied by the clamp jaws 302 to the surface of the accident vehicle. This helps to mitigate the stress on the accident vehicle, especially near the location of the accident, preventing secondary damage to the accident vehicle. Meanwhile, one frame 401 is fixed to the jaw 302, and the other frame 401 is mounted with a damping cushion 404, which further provides absorption and damping of shock and vibration during transportation. The design of the whole buffer mechanism 4 enables the hydraulic claw mechanism 3 to fix and lift the accident vehicle more stably, and the surface of the accident vehicle and the integrity of the device are protected. This design ensures the stability and safety of the operation of the mobile device when carrying an accident vehicle. It allows the device to adapt to different stress situations, thereby reducing the risk of damage to the accident vehicle and improving the efficiency and accuracy of the accident vehicle identification process.

In some embodiments of the present application, please refer to fig. 3-5 in combination: every two adjacent hydraulic buffer cylinders 402 are arranged in a V-shape or inverted V-shape with respect to each other. The arrangement mode is mainly used for improving the limit stroke quantity of the second linear degrees of freedom, so that each second linear degree of freedom is arranged in a staggered mode, and further control accuracy is improved.

In the scheme, the method comprises the following steps: the V-shaped or inverted V-shaped arrangement mode increases the limit stroke amount of the buffer mechanism in this embodiment and improves the control accuracy. This helps achieve better adaptability and stability and thus better handling during the identification of an accident vehicle.

Specific: the design of the V-shaped or inverted V-shaped arrangement pattern in this embodiment aims to optimize the adjustment range of the second linear degree of freedom. By arranging the adjacent hydraulic cushion cylinders 402 in a V-shaped or inverted V-shaped manner, the movement ranges of each cushion cylinder 403 can be made to overlap each other, thereby increasing the overall movement range. This staggered arrangement allows the motion of each cushioning cylinder 403 to be affected by adjacent cushioning cylinders, thereby allowing for a greater overall range of adjustment.

Functional elucidation of the V-shaped or inverted V-shaped arrangement mode in this embodiment is mainly used to increase the limit stroke amount of the second linear degree of freedom. By the staggered arrangement, the range of motion of each of the cushion cylinders 403 can be superimposed to some extent, thereby achieving a greater range of motion. This is very useful for accurate positioning and fixing of accident vehicle surfaces in different locations and shapes. This arrangement mode can also improve control accuracy. Because the movements of each hydraulic buffer cylinder 402 are staggered, the control system can more precisely adjust the telescopic state of each buffer cylinder to adapt to different stress conditions. This helps to maintain the stability and immobility of the hydraulic jaw mechanism, thereby improving the accuracy and efficiency of the authentication process.

Further, the hydraulic buffer cylinder 402 is a key component, and is mainly used for providing buffering and self-adapting functions so as to ensure the stability and safety of the accident vehicle during transportation:

(1) Buffering function: the hydraulic buffer cylinder 402 can realize the in-out of liquid by the hydraulic system thereof so as to control the telescopic movement of the piston rod. Such movement may be used to provide cushioning for an accident vehicle. When the hydraulic jaw mechanism contacts the accident vehicle surface and begins to lift and secure, the telescopic motion of the hydraulic buffer cylinder 402 can absorb and slow down shocks and vibrations during transport, thereby reducing the impact force and risk of damage to the accident vehicle. This helps to protect the integrity of the accident vehicle and reduces additional damage that may result during transport.

(2) Adaptivity: the hydraulic cushion cylinders 402 are arranged in a V-shape or inverted V-shape between each cushion frame 401 in such a layout that the telescopic motions of each two adjacent cushion cylinders 403 are mutually affected. This design allows the cushion cylinder 403 to automatically adapt in the event of a force, with a corresponding expansion and contraction depending on the direction and extent of the force applied. The cushion cylinder 403 can be automatically adjusted to maintain relative stability when the shape or degree of unevenness of the vehicle surface causes a difference in force applied at different positions. This helps to prevent tilting or twisting of the accident vehicle due to uneven stress, thereby ensuring smoothness and safety during transportation.

(3) The limit stroke amount is improved: the arrangement and adaptive nature of the hydraulic cushion cylinders 402 allows the telescopic strokes of each cushion cylinder to be superimposed on each other. This increases the amount of limited travel in the second linear degree of freedom, allowing greater flexibility in the device in handling accident vehicles of different shapes and locations. This capability is very useful for securing and lifting accident vehicles in different situations, especially in complex operating environments.

Summarizing, aiming at the related problems in the prior art, the specific embodiment is based on the mobile device for identifying the accident vehicle, and the following technical means or characteristics are adopted to realize the solution:

(1) Solution of restrictive fixation: in the technique of the present embodiment, the cooperation of the hydraulic arm mechanism, the hydraulic claw mechanism, and the buffer mechanism makes the fixation of the accident vehicle more accurate and flexible. For example, the angular adjustment of the hydraulic jaw mechanism can accommodate the shape of different vehicle surfaces, while the adaptive capacity of the cushioning mechanism can reduce the restriction of the fixed position during transport. This means that the technique of the present embodiment can be better adapted to various vehicle shapes and sizes, thereby solving the problem of restrictive fixation.

(2) Solution of risk of surface damage: the technique of this embodiment uses a hydraulic jaw mechanism for angular adjustment and incorporates a damping cushion in the cushioning mechanism, which reduces impact and pressure on the accident vehicle surface. In particular, the action of the angular adjustment and dampening mechanism allows finer control of the contact force of the hydraulic jaws during accident vehicle qualification, thereby reducing the risk of potential damage to the vehicle surface.

(3) Solutions that do not adapt to special situations: in the technique of the present embodiment, the design of the hydraulic arm mechanism and the hydraulic claw mechanism enables the device to be operated more flexibly in a narrow space and a complex terrain environment. For example, the telescoping and angular adjustment of the hydraulic arm can be adapted to different operating environments, while the adaptive capacity of the damping mechanism can reduce the limitations of the fixed position in special cases. This makes the technique of the present embodiment more suitable for coping with different operational demands, thereby solving the problem of inadaptation to special cases.

The above examples merely illustrate embodiments of the utility model that are specific and detailed for the relevant practical applications, but are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
