[0002] Logistics turnover equipment is a device used to hold various items in conjunction with logistics transportation. It is widely used in the field of logistics transportation and is one of the indispensable auxiliary components in this field. Electric vehicles need to use logistics transportation boxes when transporting long distances due to their two-wheeled nature.

[0003] Logistics turnover devices are generally large, complex frames or boxes. However, it has been found that manually assembling these boxes before placing electric vehicles inside is cumbersome and reduces the turnover efficiency of the vehicles. Therefore, this utility model proposes a novel solution. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an electric vehicle logistics turnover rack that can solve the problem that manual assembly is required when placing electric vehicles, which is cumbersome and reduces the turnover efficiency of electric vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric vehicle logistics turnover rack, including a first support frame; An adjustment assembly is mounted on a first support frame. The adjustment assembly includes a second support frame and a third support frame. The second and third support frames are located on the front and rear sides of the first support frame. Two racks are fixedly connected to the opposite surfaces of the second and third support frames, and all four racks are slidably connected to the first support frame. The first support frame has two rotating shafts internally connected to each other. Gears are fixedly connected to the surface of each shaft, and the two gears mesh with corresponding racks. The surface of the first support frame is provided with a first limiting groove, and the surfaces of the second support frame and the third support frame are both provided with a second limiting groove.

[0006] Preferably, the adjustment assembly further includes multiple bolt slots, which are formed on the surface of the first support frame, and the surfaces of the two racks on opposite sides of the two gears are also provided with multiple bolt slots. The bolt grooves on the two rack surfaces are connected to the internal threads of the bolt grooves on the surface of the first support frame by fixing bolts; The first support frame and the corresponding rack are fixed together by fixing bolts.

[0007] Preferably, the opposing surfaces of the second and third support frames are respectively fixedly connected to two auxiliary support plates, and the four auxiliary support plates are respectively slidably connected to the first support frame.

[0008] Preferably, the second support frame and the third support frame are provided with support column limiting grooves on their left and right sides respectively, and support columns are engaged in the interior of each of the four support column limiting grooves, and support column limiting blocks are engaged in the interior of each of the four support column limiting grooves. The four support limit blocks are fixed to the second and third support frames by bolts.

[0009] Preferably, each of the four pillars has multiple mounting grooves on its surface.

[0010] Preferably, a first sliding groove is provided on the left side of the second support frame, and two second sliding grooves are provided inside the second support frame, with a slider slidably connected inside each of the two second sliding grooves; The opposing surfaces of the two sliders are rotatably connected to an electric vehicle guide plate, which is slidably connected to the first slide groove.

[0014] Preferably, the middle part of the electric vehicle guide plate may be concave.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This electric vehicle logistics turnover rack, through the linkage design of adjustable components, can adapt to electric vehicles of different specifications without disassembling or assembling additional parts. The second and third support frames move back and forth along the first support frame, thereby expanding or shrinking the distance between the second and third support frames. During the movement, the auxiliary support plate slides synchronously along the first support frame, limiting the offset direction of the second and third support frames and preventing tilting during adjustment. When the distance matches the size of the electric vehicle, simply insert the fixing bolts into the bolt slots corresponding to the surface of the rack and pinion on the first support frame and tighten them to lock the position. This improves adaptation efficiency, reduces operation procedures, and enhances the turnover efficiency of electric vehicles.

[0016] 2. In this electric vehicle logistics turnover rack, the first slide groove on the left side of the second support frame cooperates with the second slide groove inside, allowing the electric vehicle guide plate to adjust its angle and position by sliding the slider; when the electric vehicle guide plate is adjusted to a recessed state in the middle, its recessed center can form a "guide track" adapted to the front wheel of the electric vehicle, guiding the front wheel to slide in along a preset path and avoiding direct impact with the second support frame; at the same time, the recessed structure can limit the left and right deviation of the front wheel, eliminating the need for manual adjustment of the direction, thus improving the practicality and convenience of the device.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Please see Figure 1-8 This utility model provides a technical solution: an electric vehicle logistics turnover frame, the core load-bearing frame of which is a first support frame 1, which is the core load-bearing component of the device and is made of Q235 high-strength steel to ensure no deformation when carrying electric vehicles; the second support frame 2 and the third support frame 3 are respectively set on the front and rear sides of the first support frame 1, and two racks 13 are fixedly connected to the opposite surfaces of the two. The racks 13 are slidably connected to the first support frame 1, forming a basic structure for size adjustment; the spacing between the second support frame 2 and the third support frame 3 can be changed by sliding the racks 13 to adapt to electric vehicles with different wheelbases, avoiding the cumbersome operation of traditional turnover frames that "require manual assembly of different frames".

[0024] The first support frame 1 has two rotating shafts 14 internally connected. Gears 15 are fixed on the surface of the rotating shafts 14. The gears 15 mesh with the corresponding racks 13. Rotating the rotating shafts 14 will drive the gears 15 to rotate, which will then be converted into axial sliding of the racks 13, enabling rapid adjustment of the second support frame 2 and the third support frame 3. Four auxiliary support plates 18 are also fixed on the opposite surfaces of the second support frame 2 and the third support frame 3. The auxiliary support plates 18 are slidably connected to the first support frame 1, which can limit the offset direction during adjustment, prevent the frame from tilting, and ensure adjustment stability. Multiple bolt slots 16 are opened on the surface of the first support frame 1 and the racks 13. After the fixing bolts 17 are inserted into the aligned bolt slots 16, the position of the racks 13 can be locked. No additional parts assembly is required, and the adjustment operation can be completed by only one person.

[0025] The second support frame 2 and the third support frame 3 are each equipped with two rollers 5 at their lower ends. The rollers 5 are made of wear-resistant rubber and can roll smoothly on the warehouse floor and inside the truck bed, enabling the turnover rack and the electric vehicle to move synchronously without the need for manual handling of the electric vehicle. The lower end of the first support frame 1 can be threadedly connected to four threaded rods 8. The lower end of the threaded rods 8 is rotatably connected to the support block 9 through a deep groove ball bearing. When the threaded rods 8 are rotated, the support block 9 moves vertically to support the turnover rack and prevent the turnover rack from shifting due to vibration.

[0026] The second support frame 2 has a first slide groove 19 on its left side and two second slide grooves 20 inside. A slider 21 is slidably connected in the second slide groove 20. The opposite surfaces of the sliders 21 are rotatably connected to the electric vehicle guide plate 22. The electric vehicle guide plate 22 is slidably connected to the first slide groove 19. The middle part of the electric vehicle guide plate 22 is arc-shaped and recessed, which can form a "guide track" to avoid the electric vehicle from deviating and colliding when entering the position. When not in use, the electric vehicle guide plate 22 can be completely slid into the first slide groove 19 without occupying extra space, thus solving the problem of traditional guide structures being "space-consuming and easily damaged".

[0027] The second support frame 2 and the third support frame 3 both have support column limiting grooves 10 on their left and right sides. The support column 11 is snapped into the support column limiting groove 10. The support column limiting block 12 is fixed to the support frame by bolts, which can lock the support column 11. Multiple mounting grooves are opened on the surface of the support column 11 for inserting straps to bind the electric vehicle frame. Together with the first limiting groove 6 on the surface of the first support frame 1 and the second limiting groove 7 on the surface of the second support frame 2 and the third support frame 3, a multi-layer fixation of "lateral support, body binding and wheel limiting" is formed to prevent displacement and collision during transportation.

[0028] Working principle: The first support frame 1 is the core load-bearing frame of the device. When the turnover frame needs to be fixed in a certain position, the support leg 4 is in contact with the ground to form a stable support, which prevents the turnover frame from shifting due to slight ground vibration, and provides a fixed reference for the subsequent placement of electric vehicles.

[0029] Pull the second support frame 2 and the third support frame 3 to the front and rear sides of the first support frame 1. The second support frame 2 and the third support frame 3 respectively drive the corresponding rack 13. During the movement, the rack 13 drives the corresponding gear 15 and the rotating shaft 14 to rotate, thereby expanding or shrinking the distance between them.

[0030] During the movement of the second support frame 2 and the third support frame 3, the four auxiliary support plates 18 fixed on their opposite surfaces slide synchronously along the first support frame 1. The auxiliary support plates 18 can limit the offset direction of the second support frame 2 and the third support frame 3, prevent tilting during adjustment, and ensure the overall stability of the frame. When the spacing is adapted to the size of the target electric vehicle, the fixing bolts 17 are inserted into the bolt grooves 16 on the surface of the first support frame 1 and the corresponding bolt grooves 16 on the surface of the rack 13. The fixing bolts 17 are tightened to make the first support frame 1 and the rack 13 rigidly fixed, thereby locking the position of the second support frame 2 and the third support frame 3 and completing the size adjustment.

[0031] Push the electric vehicle guide plate 22 on the second support frame 2. The electric vehicle guide plate 22 slides in the two second slide grooves 20 inside the second support frame 2 through the sliders 21 fixed at both ends. At the same time, the electric vehicle guide plate 22 can be slightly adjusted up and down along the first slide groove 19 on the left side of the second support frame 2. According to the height of the front wheel of the electric vehicle, the electric vehicle guide plate 22 is adjusted to an inclined state of "lower outside and higher inside" to form a smooth guide slope.

[0032] The front wheel of the electric vehicle is pushed into the turnover frame along the slope of the electric vehicle guide plate 22. The electric vehicle guide plate 22 can prevent the front wheel of the electric vehicle from directly hitting the second support frame 2, and at the same time guide the electric vehicle to move along the preset path until the electric vehicle body is completely entered into the space enclosed by the first support frame 1, the second support frame 2, and the third support frame 3, thus completing the initial placement.

[0033] Four pillars 11 are respectively inserted into the pillar limiting grooves 10 opened on the left and right sides of the second support frame 2 and the third support frame 3. Then, the pillar limiting block 12 is inserted into the pillar limiting groove 10. The pillar limiting block 12 is fixed to the second support frame 2 and the third support frame 3 by bolts, thereby locking the position of the pillars 11 and forming the side protection frame of the electric vehicle.

[0034] Using multiple mounting slots on the surface of the support column 11, straps or buckles are inserted to fix one end of the strap to the support column 11 and the other end to the electric vehicle frame, thus achieving longitudinal fixation of the vehicle body; at the same time, the electric vehicle wheels are inserted into the first limiting groove 6 on the surface of the first support frame 1 and the second limiting groove 7 on the surfaces of the second support frame 2 and the third support frame 3. The limiting grooves can restrict the lateral rolling of the wheels. The double fixing structure ensures that the electric vehicle is free from displacement and collision during transportation.

[0035] Furthermore, by adjusting the linkage design of the components, different specifications of electric vehicles can be adapted without disassembling or assembling additional parts. The second support frame 2 and the third support frame 3 move back and forth along the first support frame 1 to expand or shrink the distance between the second support frame 2 and the third support frame 3. During the movement, the auxiliary support plate 18 slides synchronously along the first support frame 1 to limit the offset direction of the second support frame 2 and the third support frame 3 and avoid tilting during adjustment. When the distance is adapted to the size of the electric vehicle, it is only necessary to insert the fixing bolt 17 into the bolt groove 16 corresponding to the surface of the first support frame 1 and the rack 13, and tighten it to lock the position. This improves the adaptation efficiency, reduces the operation process, and improves the turnover efficiency of electric vehicles.

[0036] The first slide groove 19 on the left side of the second support frame 2 cooperates with the second slide groove 20 inside, so that the electric vehicle guide plate 22 can be adjusted in angle and position by sliding the slider 21. When the electric vehicle guide plate 22 is adjusted to a recessed state in the middle, its recessed middle can form a "guide track" that is compatible with the front wheel of the electric vehicle, guiding the front wheel to slide in along the preset path and avoiding direct impact on the second support frame 2. At the same time, the recessed structure can limit the left and right deviation of the front wheel, eliminating the need for manual adjustment of the direction, thus improving the practicality and convenience of the device.

[0037] Example 1: Threaded rod-support block auxiliary support embodiment for warehouse temporary storage and transfer switching Remove the original support leg 4 at the lower end of the first support frame 1, and screw threaded rods 8 into the threaded holes at the four corners of the lower end of the first support frame 1 respectively; the lower end of the threaded rod 8 is rotatably connected to the support block 9 through a deep groove ball bearing, so as to ensure that when the threaded rod 8 is rotated, the support block 9 only moves in the vertical direction and does not rotate synchronously with the threaded rod 8.

[0038] Auxiliary support adjustment during temporary storage: When electric vehicles need to be temporarily stored, observe the horizontal status of the first support frame 1 using a level. If a certain corner is too low, rotate the corresponding threaded rod 8 clockwise. Due to the threaded engagement between the threaded rod 8 and the first support frame 1, the threaded rod 8 drives the support block 9 to move downwards until the support block 9 is completely in contact with the warehouse floor. Repeat the adjustment of the four sets of threaded rods 8 to keep the first support frame 1 horizontal. At this time, the turnover frame forms a stable support through the anti-slip contact between the four sets of support blocks 9 and the ground, preventing the electric vehicle from shifting due to the tilt of the turnover frame when it is temporarily stored.

[0039] Movement switching during transfer: When the electric vehicle needs to be transferred to the sorting area, rotate the four sets of threaded rods 8 counterclockwise to move the support block 9 upward until the support block 9 is completely separated from the ground; at this time, the turnover frame only contacts the ground through the rollers 5 at the lower end of the second support frame 2 and the third support frame 3. The staff pushes the first support frame 1, and the turnover frame and the electric vehicle can be moved synchronously through the rolling of the rollers 5. There is no need to disassemble the fixed structure of the electric vehicle or manually move the electric vehicle.

[0040] By replacing the threaded rod 8 with the support block 9, the threaded connection between the threaded rod 8 and the first support frame 1 can achieve precise adjustment of the support height, adapting to uneven warehouse floors and improving the anti-lateral displacement capability of the turnover rack during temporary storage; when switching to the moving state, only the threaded rod 8 needs to be rotated to separate the support block 9 from the ground, shortening the operation time, improving turnover efficiency, and adapting to the "high-frequency temporary storage and transfer" operation requirements of logistics warehouses.

[0041] Example 2: Recessed, retractable guide plate adapted for peak unloading at logistics stations The original plate-shaped electric vehicle guide plate 22 is replaced with a structure with an arc-shaped concave center. The length of the electric vehicle guide plate 22 matches the first slide groove 19. The fixed connection between the two ends of the electric vehicle guide plate 22 and the slider 21 is retained, and the slider 21 is still slidably connected to the second slide groove 20 inside the second support frame 2.

[0042] During the morning rush hour, when unloading, staff pull the electric vehicle guide plate 22 outward, causing it to slide out along the first slide groove 19. Simultaneously, the slider 21 moves along the second slide groove 20. By adjusting the position of the slider 21 within the second slide groove 20, the electric vehicle guide plate 22 is adjusted to a concave shape. At this time, the concave area in the middle of the electric vehicle guide plate 22 forms a "guide track". The electric vehicle on the truck only needs to align its front wheel with the concave area to slide naturally into the turnover rack along the slope of the electric vehicle guide plate 22. The concave structure restricts the left and right deviation of the front wheel, eliminating the need for manual adjustment of the direction.

[0043] After unloading during the morning rush hour, push the electric vehicle guide plate 22 inward so that it slides completely into the first chute 19. At this time, the outer surface of the electric vehicle guide plate 22 is flush with the side of the second support frame 2, without protruding and occupying space, thus avoiding collision damage between the electric vehicle guide plate 22 and other equipment during subsequent transfer and turnover. If it needs to be used again, simply pull out the electric vehicle guide plate 22 without reassembly.

[0044] The design of the "recessed and retractable" electric vehicle guide plate 22 solves the problems of traditional plate-shaped guide plates being "easy to deviate, space-consuming, and cumbersome to operate": the central recessed structure improves the guiding accuracy of the electric vehicle's front wheel; improves the overall unloading efficiency during peak hours; the design of the electric vehicle guide plate 22 being able to be retracted into the first slide 19 reduces the space occupied when the turnover rack is idle and avoids collision damage to the electric vehicle guide plate 22; at the same time, it adapts to the operational needs of narrow unloading areas in logistics stations, solving the pain points of "electric vehicles being difficult to enter and easy to collide" in the background technology.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
