Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle-mounted hoisting device and vehicle. Background Technology
[0002] In the traditional field of construction machinery, vehicle-mounted lifting equipment has long suffered from an inherent defect of insufficient structural integration.
[0003] Typical technical solutions often adopt a split truss structure. The folding mechanism is limited by the positioning accuracy of the pivot and the deviation of the hydraulic synchronization control, resulting in low boom deployment efficiency and limited working radius. The power matching system generally suffers from problems such as excessive hydraulic energy loss and inaccurate planning of the coordinated movement trajectory of multiple boom sections. Utility Model Content
[0004] In view of the above situation, it is necessary to provide a truck-mounted lifting device and vehicle to address the problems of low operating efficiency, limited operating radius, excessive energy loss, and inaccurate motion trajectory planning of existing lifting equipment.
[0005] A vehicle-mounted lifting device includes a fixing component, a driving component, and a lifting component. The fixing component includes a first fixing frame and a second fixing frame. One side of the first fixing frame is connected to the inner wall of the vehicle's trunk, and the side of the first fixing frame facing away from the trunk is connected to the second fixing frame via a sliding component. The driving component includes a first motor, a rack, and a gear set. The rack is located on one side of the first fixing frame, and the first motor and the gear set are located on one side of the second fixing frame, corresponding to the rack. The output end of the first motor is connected to the gear set, and the gear set meshes with the rack. The first motor drives the second fixing frame to move the second fixing frame into or out of the vehicle's trunk. The side of the second fixing frame facing away from the sliding component has a lifting component for lifting objects.
[0006] The beneficial effects of this utility model are:
[0007] The first mounting bracket is directly installed on the top of the rear of the vehicle, making full use of the vehicle's unused area. The structure is compact and does not affect the vehicle's original functions. The second mounting bracket can be moved inside and outside the vehicle via a drive component, without occupying the vehicle's internal cargo space and eliminating the need for an additional trailer. The sliding component design extends the lifting range from the rear of the vehicle to the outside, solving the problem of blind spot operation around the vehicle. The sliding component has a stable and reliable structural connection. The first motor drives the gear set to transmit power on the rack and pinion. Combined with electric control, the extension distance of the second mounting bracket and the height of the lifting component can be precisely adjusted. The automated operation is highly efficient and has a reliable operating radius. Compared with traditional hydraulic drive, the motor system has lower energy consumption. If paired with new energy vehicles, it can further reduce carbon emissions, which is in line with the trend of green transportation.
[0008] Furthermore, the sliding assembly includes two slide rails and two slider groups. The two slide rails are spaced apart at the bottom of the first fixed frame, and the two slider groups are spaced apart at the top of the second fixed frame. The slide rails are adapted to the slider groups.
[0009] Furthermore, limit switches are provided at both ends of the first fixing frame, and the slider group corresponds to the position of the limit switches.
[0010] Furthermore, the slider assembly includes a slider body and a grease filling port. The slider body is provided with a groove that passes through the slider body. The groove is adapted to the slide rail. One end of the slider body is provided with the grease filling port, and the groove communicates with the grease filling port.
[0011] Furthermore, the side of the second fixing frame facing away from the slider assembly is recessed to form a receiving space, which is used to accommodate the lifting assembly.
[0012] Furthermore, the lifting assembly includes a second motor, a rotating disk, a cable, and a hook. The second motor is connected to the second fixed frame via a connecting bracket. The output end of the second motor is connected to the rotating disk. The cable is provided on the rotating disk, and the hook is provided at the end of the cable away from the rotating disk.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.
[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.
[0024] like Figure 1-3As shown, a vehicle-mounted lifting device includes a fixing component 1, a driving component 2, and a lifting component 3. The fixing component 1 includes a first fixing frame 11 and a second fixing frame 12. One side of the first fixing frame 11 is connected to the inner wall of the vehicle's trunk, and the side of the first fixing frame 11 facing away from the trunk is connected to the second fixing frame 12 via a sliding component 4. The driving component 2 includes a first motor 21, a rack 22, and a gear set 23. The rack 22 is located on one side of the first fixing frame 11, and the first motor 21 and the gear set 23 are located on one side of the second fixing frame 12 and correspond to the rack 22. The output end of the first motor 21 is connected to the gear set 23, and the gear set 23 meshes with the rack 22. The first motor 21 is used to drive the second fixing frame 12 to move the second fixing frame 12 into or out of the vehicle's trunk. The lifting component 3 is located on the side of the second fixing frame 12 facing away from the sliding component 42, and the lifting component 3 is used to lift objects. Driven by the first motor 21, the gear set 23 rotates, thereby changing the position of the second fixed frame 12 relative to the rack 22. Since the rack 22 is mounted on the first fixed frame 11 connected to the vehicle's trunk, the change in the relative position of the second fixed frame 12 essentially enables it to move in or out of the vehicle's trunk. When the lifting assembly 3 needs to lift an object, the first motor 21 is controlled to operate, causing the second fixed frame 12 to move out of the vehicle's trunk. After successfully lifting the object, the first motor 21 is controlled again to move the second fixed frame 12 back into the vehicle's trunk, thus moving the object inside. The entire operation is simple, efficient, and smooth, requiring no additional equipment.
[0025] like Figure 1-4 As shown, specifically, the sliding assembly 4 includes two slide rails 41 and two slider groups 42. The two slide rails 41 are spaced apart at the bottom of the first fixed frame 11, and the two slider groups 42 are spaced apart at the top of the second fixed frame 12. The slide rails 41 and slider groups 42 are adapted to each other. The sliding assembly 4 consists of two parallel slide rails 41 and two slider groups 42; wherein, the slide rails 41 are fixedly installed at the bottom of the first fixed frame 11 in a spaced-apart manner, and the slider groups 42 are arranged at corresponding intervals at the top of the second fixed frame 12. The slide rails 41 and slider groups 42 form a sliding pair through a precision guide structure. This layout effectively ensures precise linear displacement, and at the same time, the symmetrical distribution design achieves balanced load transmission.
[0026] Specifically, limit switches 111 are provided at both ends of the first fixed frame 11, and the slider assembly 42 corresponds to the position of the limit switches 111. The limit switches 111 are connected to the vehicle control system. By sensing the position reached by the slider assembly 42, the limit switches 111 can accurately trigger a signal to ensure that the slider assembly 42 moves within a preset range, avoiding positioning deviations caused by exceeding the travel limit, improving the operating accuracy of the equipment, and effectively preventing the slider assembly 42 from rushing out of the fixed frame range due to loss of control or misoperation, thereby reducing the risk of equipment failure and safety hazards to operators.
[0027] Specifically, the slider assembly 42 includes a slider body 421 and a grease filling port 422. The slider body 421 has a groove 4211 that runs through it, and the groove 4211 is adapted to the slide rail 41. One end of the slider body 421 has a grease filling port 422, and the groove 4211 is connected to the grease filling port 422. The grease filling port 422 is directly connected to the groove 4211, and grease can be injected periodically to ensure continuous lubrication of the contact surface between the groove 4211 and the slide rail 41. This significantly reduces the coefficient of friction, reduces wear, and extends the service life of the slider assembly 42 and the slide rail 41. Lubrication maintenance can be completed without frequent disassembly of the slider body 421, simplifying the operation process and reducing downtime.
[0028] Specifically, the side of the second fixed frame 12 facing away from the slider assembly 42 is recessed to form a receiving space 121, which is used to accommodate the lifting assembly 3. The receiving space 121 is integrally formed with the second fixed frame 12, providing a stable mounting base for the lifting assembly 3, reducing the risk of displacement caused by vibration or load changes during operation. The recessed structure can increase the local cross-sectional moment of inertia of the second fixed frame 12, improving its bending and torsional resistance. The receiving space 121 relatively isolates the lifting assembly 3 from the external environment, while avoiding interference with other moving parts, thus improving reliability.
[0029] Specifically, the lifting assembly 3 includes a second motor 31, a rotating disk 32, a cable 33, and a hook 34. The second motor 31 is connected to the second fixed frame 12 via a connecting bracket 5. The output end of the second motor 31 is connected to the rotating disk 32, which has a cable. The end of the cable 33 away from the rotating disk 32 is equipped with a hook 34. The second motor 31 drives the rotating disk 32 to rotate. The forward or reverse rotation of the rotating disk 32 extends or retracts the cable 33, thereby changing the height of the hook 34. The lifting assembly 3 can be independently installed and removed from the receiving space 121 via the connecting bracket 5 without disassembling the entire second fixed frame 12 or the slider assembly 42, thus shortening maintenance time and reducing downtime costs.
[0030] Specifically, the second motor 31 is equipped with an electrical control switch 311 for controlling the second motor 31. The electrical control switch 311 extends towards the ground for easy operation by the operator.
[0031] Specifically, the end of the second motor 31 facing the rotating disk 32 is provided with a limiting bracket 35, and the end of the cable 33 facing away from the rotating disk 32 passes through the limiting bracket 35. This end of the cable 33 is connected to a limiting plate 36, the horizontal cross-sectional area of which is larger than that of the limiting bracket 35. This larger horizontal cross-sectional area ensures that the limiting plate 36 cannot pass through the limiting bracket 35 and approach the rotating disk 32, thus ensuring the normal operation of the rotating disk 32. Simultaneously, the limiting bracket 35 also relatively restricts the swing range of the cable 33, ensuring the stability of the movement after the object is lifted.
[0032] This invention directly mounts the first fixed frame 11 on the top of the rear of the vehicle, making full use of the vehicle's unused area. The structure is compact and does not affect the vehicle's original functions. The second fixed frame 12 can move inside and outside the vehicle via the drive component 2, without occupying the vehicle's internal cargo space and avoiding the need for an additional trailer. The sliding component 4 extends the lifting range from the rear of the vehicle to the outside, solving the problem of blind spot operation around the vehicle. The structure of the sliding component 4 is stable and reliable. The first motor 21 drives the gear set 23 to transmit power on the rack 22. Combined with electric control, the extension distance of the second fixed frame 12 and the height of the lifting component 3 can be precisely adjusted. The automated operation is highly efficient and the working radius is reliable. Compared with traditional hydraulic drive, the motor system has lower energy consumption. If paired with new energy vehicles, it can further reduce carbon emissions, which is in line with the trend of green transportation.
