[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example 1
[0032] like Figures 1 to 9 As shown, a left and right correction device for a detachable vehicle includes a detachable vehicle chassis 1 and a cargo box 2 mounted on top of the detachable vehicle chassis 1. Correction frames 3 are provided at the four corners of the detachable vehicle chassis 1, and correction mechanisms are provided on both sides of the top of the correction frames 3. Support frames 4 are fixedly connected to the four corners of the bottom of the cargo box 2.
[0033] like Figures 1 to 3 As shown, the position of the correction frame 3 on the detachable vehicle chassis 1 corresponds one-to-one with the position of the support frame 4 at the bottom of the carriage 2. The top of the correction frame 3 is a symmetrical arc shape, and the support frame 4 is an isosceles trapezoid. By setting the correction frame 3 and the support frame 4 on the detachable vehicle chassis 1 and the carriage 2 respectively, when the carriage 2 is assembled onto the detachable vehicle chassis 1, the inclined surface at the bottom of the support frame 4 interacts with the correction mechanism on both sides of the correction frame 3 to generate a lateral force to guide and correct the carriage 2. This allows the carriage 2 and the detachable vehicle chassis 1 to automatically perform correction and positioning during the assembly process, avoiding situations where the two cannot be assembled or are not firmly assembled due to misalignment during the assembly process.
[0034] like Figures 4 to 5 As shown, the front and rear sides of the support frame 4 are closed. The thickness of the support frame 4 is less than the inner wall width of the correction frame 3. The support frame 4 is fixedly connected with ribs 5. By closing the front and rear sides of the support frame 4, the support frame 4 becomes a box-type structure, which improves the overall compressive load resistance of the support frame 4. This allows the support frame 4 to withstand greater pressure when it contacts the correction frame 4 for positioning and correction, avoiding excessive stress and deformation of the support frame 4 due to the large amount of cargo loaded in the carriage 2, which would affect the smoothness of the correction and positioning. The ribs 5 inside the support frame 4 can further improve the compressive strength of the support frame 4, enabling it to maintain a longer service life under long-term high-pressure impact.
[0035] like Figure 4As shown, several circular holes 6 are provided on both the front and rear sides of the support frame 4 and the correction frame 3. By providing circular holes 6 on the support frame 4 and the correction frame 3, the circular holes 6 can serve as stress relief holes for the correction frame 3 and the support frame 4, guiding the stress of the correction frame 3 and the support frame 4 to transfer to the low stress area, avoiding crack propagation, and forming a uniform stress gradient field, reducing overall stress fluctuation, achieving equivalent stiffness design, and extending the service life of both. Example 2
[0036] like Figures 4 to 5 As shown, the correction mechanism includes two fixed columns 7 fixedly connected to the two sides inside the correction frame 3, and rolling pulleys 8 sleeved on the outside of the fixed columns 7. By setting fixed columns 7 with rolling pulleys 8 on both sides of the correction frame 3, when there is a deviation during the docking of the carriage 2, the support frame 4 contacts the rolling pulleys 8. Under the action of the inclined surface of the support frame 4, the vertical force is converted into a horizontal force, which drives the support frame 4 and the carriage 2 to move left and right to complete the correction and positioning. This correction device enables the correction mechanisms on both sides of the chassis to perform correction and positioning synchronously, making the correction of the carriage 2 smoother. Example 3
[0037] like Figure 6 As shown, the correction mechanism includes three fixed posts 7 that are fixedly connected to both sides of the inside of the correction frame 3, and rolling pulleys 8 that are sleeved on the outside of the fixed posts 7. By setting three fixed posts 7 and rolling pulleys 8 on each side, the distance between the rolling pulleys 8 is reduced, and the situation where the support frame 4 gets stuck in the gap between two rolling pulleys 8 is avoided, which would lead to incomplete correction.
[0038] like Figures 4 to 6 As shown, the height of each rolling pulley 8 gradually decreases from the outside to the inside. The width of the rolling pulley 8 is matched with the width of the support frame 4. The coefficient of friction between the fixed column 7 and the rolling pulley 8 is less than one. By gradually reducing the height of the rolling pulley 8, the rolling pulley 8 is combined to form an inclined surface, which interacts with the inclined surfaces on both sides of the bottom of the support frame 4, thereby guiding the support frame 4 and the carriage 2 to move left and right to complete the correction. Limiting the coefficient of friction between the rolling pulley 8 and the fixed column 7 to less than one can reduce friction and make the rotational resistance of the rolling pulley 8 smaller, so that the correction of the support frame 4 and the carriage 2 is smoother.
[0039] Furthermore, the rolling pulley 8 and the fixed column 7 are rotatably connected by bearings, which improves the stability of the rolling pulley 8 when it rotates, reduces rolling resistance, and improves its durability.
[0040] like Figure 4As shown, the bottom of the support frame 4 is provided with a rounded corner on both sides, and the rounded corner on both sides of the support frame 4 can make the contact process of the support frame 4 and the rolling pulley 8 more smooth, and the arc surface of the rounded corner guides the support frame 4 to separate from the upper rolling pulley 8, and gradually completes the centering of the support frame 4 and the deviation correction frame 3, thereby avoiding the situation that the support frame 4 stops at the gap between the two rolling pulleys 8.
[0041] As shown in the drawings, Figure 4 As shown, the inner side of the deviation correction frame 3 is fixedly connected with a mounting plate 9, the mounting plate 9 is provided with a mounting hole 10, and the mounting plate 9 is fixedly connected with the detachable automobile chassis 1 through the mounting hole 10 and a screw. Embodiment 4
[0042] As shown in the drawings, Figures 7 to 9 As shown, the deviation correction mechanism includes guide plates 11 fixedly connected to the inner sides of the deviation correction frame 3, spherical grooves 12 provided on the top of the guide plates 11, and cow eye bearing balls 13 rollingly connected to the inside of the spherical grooves 12, and the top of the cow eye bearing ball 13 is located outside the guide plate 11, and the guide plate 11 and the cow eye bearing ball 13 are arranged on both sides of the deviation correction frame 3, and the inclined surface of the guide plate 11 and the rolling friction of the cow eye bearing ball 13 are matched with the inclined surface of the support frame 4, so that the left and right movement of the carriage 2 with the support frame 4 is completed to position and correct the deviation;
[0043] Further, the size of the deviation correction frame is 55-65 cm long, 10-16 cm wide, and 16-25 cm high, the length of the rolling pulley is 10-14 cm, the outer diameter of the rolling pulley is 5-8 cm, the inner diameter of the rolling pulley is 2-4 cm, and the diameter of the cow eye bearing ball is 5-8 cm.
[0044] The working principle of the utility model is as follows:
[0045] S1, when the carriage 2 is assembled to the detachable automobile chassis 1, the inclined surface at the bottom of the support frame 4 interacts with the deviation correction mechanism on both sides of the deviation correction frame 3 to generate a horizontal force to guide and correct the deviation of the carriage 2, so that the carriage 2 and the detachable automobile chassis 1 can be automatically positioned and corrected during assembly;
[0046] S2, under the action of the inclined surface of the support frame 4, the vertical force is converted into a horizontal force to drive the left and right movement of the support frame 4 and the carriage 2 to complete the deviation correction positioning, and the deviation correction device can make the deviation correction mechanisms on both sides of the chassis synchronize the deviation correction positioning, so that the deviation correction of the carriage 2 is more smooth;
[0047] S3, the rolling pulley 8 is combined to form an inclined surface, which interacts with the inclined surface at the bottom of the support frame 4 to guide the left and right movement of the support frame 4 and the carriage 2 to complete the deviation correction;
[0048] S4, the rolling friction of the inclined surface of the guide plate 11 and the ball 13 of the bull eye bearing cooperates with the inclined surface of the support frame 4, so that the carriage 2 with the support frame 4 moves left and right to complete positioning and deviation correction.
[0049] The above merely aims to explain the technical scheme of the present application but not limit it, and other modifications or equivalent replacements to the technical scheme of the present application made by those skilled in the art shall be covered in the scope of the claims of the present application as long as they do not depart from the spirit and range of the technical scheme of the present application.
