Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle body. Background Technology
[0002] For pickup trucks with open cargo beds, the lack of a roof makes the cargo vulnerable to damage from rain, snow, and sun during transport. Therefore, many pickup trucks on the market now have a covered cargo bed installed to protect the goods inside. However, sealing the cargo bed with a covered cargo bed significantly reduces the cargo volume, thus affecting the load capacity.
[0003] Currently, upward-protruding cargo compartments are appearing on the market, with openable roofs. Due to the upward protrusion, a larger load-bearing space is created between the top and bottom of the compartment, allowing it to carry more cargo compared to compartments with flat roofs. The roof also provides shelter and protection for the loaded goods. However, there are two types of roofs: one type is hinged at one end near the front of the compartment, generally larger in size, and opens from the rear of the compartment to a certain angle. Because of its long wingspan and lever arm, opening and closing this type is inconvenient, and the interior space near the front is limited by the opening angle of the roof, making it impossible to accommodate some larger items. The other type is hinged at one end near the rear of the compartment, generally smaller in size, and opens from the rear of the compartment to a certain angle. While this type has a shorter wingspan and lever arm, making it easier to open and close, the hinged position near the rear of the compartment prevents the loading of items larger than the distance between the top and bottom of the compartment. Summary of the Invention
[0004] Therefore, the purpose of this invention is to provide a carriage with a convenient top cover that can be opened and closed and is capable of carrying large cargo.
[0005] This invention provides a carriage, including a carriage body, a first carriage cover, a second carriage cover, and an opening and closing mechanism. The inner surface of the first carriage cover has a support portion and is hinged to the side wall of the carriage body. When the first carriage cover is closed, its inner surface is against the inner side of the side wall of the carriage body. The second carriage cover is hinged to the first carriage cover. When the second carriage cover is unfolded, its inner surface presses against the support portion. When the second carriage cover is closed, its inner surface lies flat on the bottom of the carriage body. The opening and closing mechanism includes a driving component and an arc-shaped transmission component. The driving component is disposed on the carriage body. One end of the arc-shaped transmission component penetrates the side wall of the carriage body and abuts against the inner surface of the first carriage cover. The driving component acts on the other end of the arc-shaped transmission component, causing the arc-shaped transmission component to reciprocate along the rotation path direction of the first carriage cover.
[0006] The aforementioned carriage features a simple opening and closing mechanism. The first and second carriage covers are designed to rotate vertically along the width of the carriage. Compared to existing one-piece carriage roofs hinged near the front of the carriage, the extended wingspan and lever arm of the first and second carriage covers are shorter, facilitating easier opening and closing. Furthermore, when the first and second carriage covers are retracted without obstructing the carriage's top space, the first carriage cover can fit snugly against the inner side wall of the carriage body, and the inner surface of the second carriage cover can be completely flat against the bottom surface of the carriage body. Compared to existing carriages, the first and second carriage covers do not occupy the carriage's top or interior space, effectively increasing the carriage's capacity and allowing for the loading of large cargo.
[0007] In addition, the carriage according to the above-described invention may also have the following additional technical features:
[0008] Furthermore, the second vehicle cover is provided with a retractable anti-slip structure, which includes a telescopic groove, an anti-slip block, and a first elastic support member: the telescopic groove array is disposed through the inner and outer surfaces of the second vehicle cover, the anti-slip block is limited in the telescopic groove, and the thickness of the anti-slip block is greater than the thickness of the second vehicle cover; the first elastic support member is used to provide a supporting force for the anti-slip block to extend out of the inner surface of the second vehicle cover.
[0009] Furthermore, the second compartment cover has several flow chambers arranged side by side along its length. The width of the flow chamber is greater than the width of the telescopic groove, and the flow chamber passes through the telescopic groove on its extension path. The anti-blocking block extends baffles into the flow chambers on both sides. The elastic support is a spring disposed between the baffle and the upper inner wall of the flow chamber.
[0010] Furthermore, the second compartment cover is provided with a cleaning structure, which includes a water inlet, a fixing component, and a sliding component. The water inlet penetrates the outer surface of the second compartment cover and communicates with the flow cavity. The fixing component is located at the water inlet and communicates with the flow cavity inside. The sliding component is located on the periphery of the fixing component and can slide up and down relative to the fixing component to control the opening and closing of the water inlet and the flow cavity.
[0011] Furthermore, the sliding assembly includes a sealing block, a support block, and a second elastic support member. The sealing block is fitted into the water inlet and has a cross-shaped opening in the center. Multiple support blocks are circumferentially spaced on the lower surface of the sealing block. The second elastic support member is fixedly connected between the lower surface of the sealing block and the inner wall of the lower side of the flow cavity. The fixing assembly includes a cross plate and a support frame. The cross plate is fitted into the cross-shaped opening of the sealing block. Multiple support frames are fixedly connected between the lower surface of the cross plate and the inner wall of the lower side of the flow cavity.
[0012] Furthermore, the second compartment cover is provided with a drainage cavity extending through its width side. The drainage cavity is connected to each of the flow passages. The drainage cavity is provided with a drainage sealing mechanism, which includes a sealing plate and at least one set of elastic tensioning members. The sealing plate has a side plate on one side and a baffle on the adjacent side. A recess is formed by the side plate and the baffle, and the recess is connected to the flow passage. The side plate can slide along the length of the drainage cavity to allow the baffle to open and close the opening of the drainage cavity. The two ends of the elastic tensioning member are respectively fixedly connected to the inner wall of the flow passage and the baffle. The elastic tensioning member is used to apply a pulling force to close the opening of the drainage cavity by the baffle.
[0013] Furthermore, there are two first carriage covers, which are arranged opposite each other and hinged to the two side walls of the carriage body respectively; there are two second carriage covers, which are arranged opposite each other and hinged to the first carriage covers on both sides respectively, and a locking and sealing structure is provided between the two second carriage covers.
[0014] Furthermore, the locking and sealing structure includes a first mounting groove, a second mounting groove, and at least one set of elastic connectors. A first magnetic element is fixedly disposed inside the first mounting groove. The second mounting groove is disposed opposite to the first mounting groove. A second magnetic element capable of attracting the first magnetic element is slidably disposed inside the second mounting groove, and the second magnetic element partially extends into the first mounting groove. The elastic connector is used to apply a reverse pulling force to the second magnetic element that slides due to the attraction of the first magnetic element.
[0015] Furthermore, the second magnetic component is provided with a receiving cavity arranged along its sliding direction and opening towards the second mounting groove. The elastic connecting component is a spring with its two ends fixedly connected to the bottom wall of the second mounting groove and the inner wall of the closed side of the receiving cavity, respectively. The cross-sectional height of the first magnetic component facing the first mounting groove is greater than the cross-sectional height of the first magnetic component away from the first mounting groove, and the cross-sectional height of the second magnetic component is greater than the cross-sectional height of the first magnetic component away from the first mounting groove.
[0016] Furthermore, a rotating rod is rotatably connected to the rear side of the main body of the carriage, and a tail plate is fixedly connected to the rotating rod. The two sides of the inner side of the tail plate are symmetrically provided with sliding grooves, and a movable plate is slidably arranged in each of the two sliding grooves. A convex ball is fixedly arranged on the outer side of each movable plate, and the convex ball abuts against the outer surface of the first carriage cover. Attached Figure Description

[0031] To facilitate understanding of the present invention, several embodiments are given below. However, the present invention 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 the present invention will be more thorough and complete.
[0032] refer to Figures 1 to 8 A carriage according to an embodiment of the present invention includes a carriage body 100, a first carriage cover 200, a second carriage cover 300, and an opening and closing mechanism 400.
[0033] A fixing post 140 is fixedly connected to the inner side wall of the main body 100 of the carriage. The first carriage cover 200 is rotatably connected to the fixing post 140, and its inner surface is also provided with a support, so that the first carriage cover 200 can rotate up and down relative to the side wall of the main body 100 of the carriage. One end of the second carriage cover 300 is hinged to the first carriage cover 200, so that the second carriage cover 300 can rotate up and down relative to the first carriage cover 200 and can press against the support when rotating. An opening and closing mechanism 400 is provided between the main body 100 of the carriage and the first carriage cover 200. The opening and closing mechanism 400 can drive the first carriage cover 200 to rotate up and down along the height direction of the main body 100 of the carriage.
[0034] Specifically, such as Figures 1 to 3 As shown, the opening and closing mechanism 400 includes a driving component 410 and an arc-shaped transmission component 420. The driving component 410 is mounted on the main body 100 of the carriage, and the arc-shaped transmission component 420 partially penetrates the side wall of the main body 100 of the carriage and abuts against the inner surface of the first carriage cover 200.
[0035] When the driving component 410 drives the arc-shaped transmission component 420 to continue extending into the interior of the carriage body 100, the first carriage cover 200 will rotate upward under the support force provided by the arc-shaped transmission component 420, thereby driving the second carriage cover 300 to move upward; when the driving component 410 drives the arc-shaped transmission component 420 to extend outward from the carriage body 100, the first carriage cover 200 will rotate downward under the action of gravity along with the arc-shaped transmission component 420, while driving the second carriage cover 300 to move downward. The first carriage cover 200 will eventually fit against the inner side wall of the carriage body 100, and the inner surface of the second carriage cover 300 will be completely flat on the bottom surface of the carriage body 100.
[0036] Optional, such as Figure 3 As shown, the driving component 410 includes a hollow protective shell 411 and a motor 412. The outer wall of the protective shell 411 is fixedly connected to the outer wall of the carriage body 100. The motor 412 is installed inside the protective shell 411. The output shaft of the motor 412 is fixedly connected to one end of the arc-shaped transmission component 420. The other end of the arc-shaped transmission component 420 passes through the side wall of the carriage body 100 and abuts against the inner surface of the first carriage cover 200. When the motor 412 rotates forward and backward, it drives the arc-shaped transmission component 420 to extend inside and outside the carriage body 100, thereby realizing the rotation of the first carriage cover 200 up and down along the height direction of the carriage body 100.
[0037] It is understandable that using an electric motor to drive the drive unit 410 is only one possible implementation method; other drive devices, such as cylinders or hydraulic cylinders, can also be used.
[0038] When the opening and closing mechanism 400 drives the first compartment cover 200 to rotate to the highest position, the support part causes the first compartment cover 200 and the second compartment cover 300 to close the top space of the compartment body 100. When the opening and closing mechanism 400 drives the first compartment cover 200 to rotate to the lowest position, due to the presence of the support part, the inner surface of the second compartment cover 300 can first contact the bottom surface of the compartment body 100, and finally the inner surface of the second compartment cover 300 can be completely laid flat on the bottom surface of the compartment body 100.
[0039] Optional, such as Figure 3 As shown, the support is a stop block 210, which is located at the rotatable connection between the first carriage cover 200 and the second carriage cover 300. One end of the stop block 210 is fixed to the inner surface of the first carriage cover 200, and the other end of the stop block 210 abuts against the inner surface of the second carriage cover 300. When the opening and closing mechanism 400 drives the first carriage cover 200 to rotate upward along the height direction of the carriage body 100, the stop block 210 supports the second carriage cover 300. When the opening and closing mechanism 400 drives the first carriage cover 200 to rotate downward along the height direction of the carriage body 100, the stop block 210 restricts the second carriage cover 300 from rotating freely downward relative to the first carriage cover 200, preventing the outer surface of the second carriage cover 300 from contacting the bottom surface of the carriage body 100 first, thus preventing the first carriage cover 200 from rotating downward.
[0040] In some embodiments, such as Figure 3 As shown, the inner side wall of the carriage body 100 is provided with a strip groove 110 that matches the stop block 210. The length, width, and height of the strip groove 110 are all greater than the length, width, and height of the stop block 210. When the first carriage cover 200 is rotated to the lowest position, the first carriage cover 200 is attached to the inner side wall of the carriage body 100, and the stop block 210 abuts against the strip groove 110. At this time, the inner surface of the second carriage cover 300 is completely flat on the bottom surface of the carriage body 100.
[0041] In some embodiments, such as Figure 3 and Figure 5 As shown, the surface of the second compartment cover 300 is provided with a retractable anti-slip structure 500. The retractable anti-slip structure 500 is used to provide sliding resistance for the goods carried on the outer surface of the second compartment cover 300 when the second compartment cover 300 is laid flat on the bottom surface of the compartment body 100.
[0042] Specifically, such as Figure 3 and Figure 5As shown, the retractable anti-slip structure 500 includes a telescopic groove 510, an anti-slip block 520, and a first elastic support member 530. The telescopic groove 510 penetrates the inner and outer surfaces of the second vehicle cover 300 and is distributed at intervals along the inner and outer surfaces of the second vehicle cover 300. The anti-slip block 520 is installed in the telescopic groove 510 and can move up and down along the telescopic groove 510 but cannot be completely removed from the telescopic groove 510. The thickness of the anti-slip block 520 is greater than the thickness of the second vehicle cover 200, so that one end of the anti-slip block 520 can partially extend out of the telescopic groove 510.
[0043] When the inner surface of the second carriage cover 300 is not in contact with the bottom surface of the carriage body 100, the first elastic support member 530 can provide support for the lower part of the anti-slip block 520 to extend out of the inner surface of the second carriage cover 300, while the upper surface of the anti-slip block 520 will not exceed the outer surface of the second carriage cover 300. Preferably, at this time, the upper surface of the anti-slip block 520 is flush with the outer surface of the second carriage cover 300. In this way, when the first carriage cover 200 and the second carriage cover 300 close the top space of the carriage body 100, the wind resistance on the top of the carriage can be reduced, and at the same time, pollutants adhering to the upper surface of the anti-slip block 520 are easily blown away by the airflow.
[0044] When the inner surface of the second carriage cover 300 is in contact with the bottom surface of the carriage body 100, the bottom surface of the carriage body 100 provides an upward force to counteract the supporting force applied by the first elastic support member 530. This causes the upper surface of the anti-slip block 520 to extend beyond the telescopic groove 510 and beyond the outer surface of the second carriage cover 300. At this time, the lower surface of the anti-slip block 520 is flush with the inner surface of the second carriage cover 300, increasing the roughness of the outer surface of the second carriage cover 300. When goods are placed on the outer surface of the second carriage cover 300, the friction between the bottom of the goods and the outer surface of the second carriage cover 300 is increased, ensuring that the goods will not slide during transportation.
[0045] In some embodiments, such as Figure 5 As shown, several flow cavities 310 are arranged side by side along the length of the second compartment cover 300. The width of the flow cavity 310 is greater than the width of the telescopic groove 510, and the flow cavity 310 passes through the telescopic groove 510 in its extension path. The anti-slip block 520 extends baffles 521 into the flow cavities 310 on both sides.
[0046] Optionally, the first elastic support 530 is a spring disposed between the baffle 521 and the upper inner wall of the flow cavity 310. When the weather is good and it is not necessary to cover the goods inside the main body 100 of the carriage, the inner surface of the second carriage cover 300 is in contact with the bottom surface of the main body 100 of the carriage. During the contact process, the lower end surface of the anti-slip block 520 first contacts the bottom surface of the main body 100 of the carriage. The second carriage cover 300 continues to deflect downward, and the spring is compressed and deformed, ultimately making the lower end surface of the anti-slip block 520 consistent with the height of the inner surface of the second carriage cover 300 and the upper end surface of the anti-slip block 520 higher than the outer surface of the second carriage cover 300. When the weather is bad and it is necessary to cover the goods inside the main body 100 of the carriage, the second carriage cover 300 is lifted, and the spring rebounds to reset the anti-slip block 520, that is, the upper end surface of the anti-slip block 520 is consistent with the height of the outer surface of the second carriage cover 300 and the lower end surface of the anti-slip block 520 is higher than the inner surface of the second carriage cover 300.
[0047] It is understandable that the first elastic support 530 may also be made of other devices, mechanisms or parts that can provide support for the anti-slip block 520 to extend out of the inner surface of the second compartment cover 300, such as elastic airbags, springs, etc.
[0048] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, a cleaning structure 600 is provided on the second compartment cover 300. The cleaning structure 600 includes a water inlet 610, a fixing component 620, and a sliding component 630. The water inlet 610 penetrates the outer surface of the second compartment cover 300 and communicates with the flow cavity 310. The fixing component 620 is located at the water inlet 610, and the interior of the fixing component 620 communicates with the flow cavity 310. The sliding component 630 is located on the periphery of the fixing component 620. When an external force is applied to the sliding component 630, the sliding component 630 can slide up and down relative to the fixing component 620, thereby controlling the opening and closing of the water inlet 610 and the flow cavity 310.
[0049] Furthermore, such as Figure 6 As shown, the sliding assembly 630 includes a sealing block 631, a support block 632, and a second elastic support member 633. The sealing block 631 is fitted into the water inlet 610, and a cross-shaped opening is provided in the middle of the sealing block 631. Four arc-shaped support blocks 632 are circumferentially spaced on the lower surface of the sealing block 631. The second elastic support member 633 is a spring fixedly connected between the lower surface of the sealing block 631 and the inner wall of the lower side of the flow cavity 310. The fixing assembly 620 includes a cross plate 621 and support frames 622. The cross plate 621 is fitted into the cross-shaped opening of the sealing block 631, and four support frames 622 are fixedly connected between the lower surface of the cross plate 621 and the inner wall of the lower side of the flow cavity 310.
[0050] When the sealing block 631 is pressed by external force, it moves downward to the underside of the cross plate 621, eventually bringing the underside of the support block 632 into contact with the inner wall of the lower side of the flow cavity 310. At this time, external water can flow into the lower space of the cross plate 621 through the space between the upper surface of the sealing block 631 and the lower surface of the cross plate 621. Since the lower space of the cross plate 621 is connected to the flow cavity 310 at this time, water can flow into the flow cavity 310. After the external force applied to the sealing block 631 is removed, the sealing block 631 is reset by the spring force, and the water inlet 610 is closed.
[0051] In some embodiments, such as Figure 4 and Figure 7 As shown, the second carriage cover 300 is provided with a drainage cavity 320 that extends through its width side. The drainage cavity 320 is connected to each flow cavity 310. The drainage cavity 320 is provided with a drainage sealing mechanism 700.
[0052] The drainage sealing mechanism 700 includes a sealing plate 710 and at least one set of elastic tensioning members 720. The sealing plate 710 has side plates 711 on its left and right sides, a baffle 712 on its front side, and a hollowed-out rear side. A recess 713 is formed by the side plates 711 and the baffle 712, and the recess 713 connects to the flow cavity 310. The side plates 711 can slide along the inner wall of the drainage cavity 320. Specifically, the baffle 712 is larger than the opening size of the drainage cavity 320, and the lower inner wall surface of the drainage cavity 320 is at the same height as the lower inner wall surface of the flow cavity 310.
[0053] The two ends of the elastic tensioning member 720 are fixedly connected to the inner wall of the flow cavity 310 and the baffle 712, respectively, and are used to apply a pulling force to close the opening of the drain cavity 320 by the baffle 712.
[0054] When goods are placed on the outer surface of the second compartment cover 300, contaminants will contaminate the outer surface of the second compartment cover 300 and part of the surface of the anti-slip block 520. Since the anti-slip block 520 can slide up and down along the telescopic groove 510, it will carry the contaminants on its surface into the flow cavity 310. When cleaning is required, the first compartment cover 200 and the second compartment cover 300 are closed by the opening and closing mechanism 400 to seal the top space of the main body 100 of the compartment. Then, the water gun is used to rinse the outer surface of the second compartment cover 300. Next, the water gun outlet is used to press down on the surface of the sealing block 631. The sealing block 631 moves down to the lower side of the cross plate 621, and finally the lower side of the support block 632 contacts the inner wall of the lower side of the flow cavity 310. At this time, the water jet from the water gun flows into the lower space of the cross plate 621 through the space between the upper surface of the sealing block 631 and the lower surface of the cross plate 621. Since the lower space of the cross plate 621 is connected to the flow cavity 310 at this time, the water then flows into the flow cavity 310. The water flow carries the pollutants inside the flow chamber 310 to the sealing plate 710 through the drain chamber 310. Under the action of water pressure, the side plate 711 of the sealing plate 710 slides along the inner wall of the drain chamber 320, thereby extending the baffle 712 to open the opening of the flow chamber 310. The water carrying the pollutants is discharged from the flow chamber 310 through the recess 713, thereby achieving the effect of cleaning the pollutants inside the flow chamber 310.
[0055] Because the elastic tensioner 720 is in a stretched state when cleaning contaminants inside the flow cavity 310, the sealing plate 710 is reset by the tension of the elastic tensioner 720 after cleaning, thus closing the opening of the drain cavity 320. It is understood that the elastic tensioner 720 can be an elastic element such as a spring.
[0056] In some embodiments, such as Figures 1 to 3 As shown, two first compartment covers 200 are provided, which are arranged opposite each other and hinged to the side walls on both sides of the main body 100. Correspondingly, two second compartment covers 300 are also provided, which are arranged opposite each other and hinged to the two first compartment covers 200. A locking and sealing structure 800 is provided between the two second compartment covers 300. By providing the locking and sealing structure 800, when cleaning is carried out in the top space of the main body 100 closed by the first compartment covers 200 and the second compartment covers 300, water carrying contaminants from the outer surface of the second compartment covers 300 will not flow into the interior of the main body 100, thus preventing contamination of the interior of the main body 100.
[0057] In some embodiments, such as Figure 5As shown, the locking and sealing structure 800 includes a first mounting groove 810, a second mounting groove 820, and an elastic connector 830. A first magnetic element 811 is fixed inside the first mounting groove 810. The second mounting groove 820 is disposed opposite to the first mounting groove 810. A second magnetic element 821 that can attract the first magnetic element 811 is slidably disposed inside the second mounting groove 820, and the second magnetic element 821 can partially extend into the first mounting groove 810. When the first carriage cover 200 and the second carriage cover 300 close the top space of the carriage body 100, the two second carriage covers 300 will move closer to each other. Due to the magnetic force, the first magnetic component 811 and the second magnetic component 821 will slide outward along the inner wall of the second mounting groove 820. Eventually, the second magnetic component 821 will partially slide into the first mounting groove 810 and fit tightly against the first magnetic component 811, thus sealing the gap between the two second carriage covers 300. At this time, the elastic connector 830 will apply a reverse pulling force to the sliding second magnetic component 821. When the second carriage cover 200 moves downward, the reverse pulling force applied by the elastic connector 830 can partially counteract the magnetic force between the first magnetic component 811 and the second magnetic component 821, thereby facilitating the separation of the two second carriage covers 300.
[0058] In some embodiments, such as Figure 5 As shown, the second magnetic component 821 has a receiving cavity 822 arranged along its sliding direction and opening towards the second mounting groove 820. The elastic connector 830 is a spring whose two ends are respectively fixedly connected to the bottom wall of the second mounting groove 820 and the inner wall of the closed side of the receiving cavity 822. The cross-sectional height of the first magnetic component 811 facing the first mounting groove 810 is greater than the cross-sectional height of the first magnetic component 811 away from the first mounting groove 810, and the cross-sectional height of the second magnetic component 821 is greater than the cross-sectional height of the first magnetic component 811 away from the first mounting groove 810. When the first magnetic component 811 and the second magnetic component 821 are tightly fitted, a drainage channel can be formed between the upper surfaces of the first magnetic component 811 and the second magnetic component 821. Water carrying pollutants after being rinsed by a water gun on the outer surface of the second carriage cover 300 can be discharged to the rear of the carriage through this drainage channel.
[0059] Optionally, the first magnetic element 811 and the second magnetic element 821 are magnets with opposite magnetic properties. It is understood that other magnetic elements or devices may also be used, such as electromagnets, combinations of magnets and good conductors of magnetism, etc.
[0060] In some embodiments, such as Figure 2 and Figure 8As shown, a rotating rod 120 is rotatably connected to the rear side of the main body 100 of the carriage. A tail plate 130 is fixedly connected to the rotating rod 120. Sliding grooves 131 are symmetrically provided on both sides of the inner side of the tail plate 130. Moving plates 132 are slidably arranged in both sliding grooves 131. A protruding ball 133 is fixedly provided on the outer side of each moving plate 132. The protruding ball 133 abuts against the outer surface of the first carriage cover 200.
[0061] As the first compartment cover 200 on one side of the opening and closing mechanism 400 gradually rotates to its lowest position, one end of the inner surface of the second compartment cover 300 on that side will first contact the bottom surface of the compartment body 100. As the first compartment cover 200 continues to rotate downwards, it will fit against the inner side wall of the compartment body 100. At this time, the inner surface of the second compartment cover 300 will be completely fitted against the bottom surface of the compartment body 100, thus realizing the function of accommodating the first compartment cover 200 and the second compartment cover 300. The same method is then used to accommodate the first compartment cover 200 and the second compartment cover 300 on the other side. When the first compartment cover 200 and the second compartment cover 300 descend, because the lower side of the convex ball 133 loses the upward supporting force applied to the first compartment cover 200, the moving plate 132 falls downwards along the slide groove 131 into the interior of the tail plate 130.
[0062] As the first compartment cover 200 on the drive side of the opening and closing mechanism 400 gradually rotates to its highest position, the first compartment cover 200 rotates upward. Due to the support of the stop block, the first compartment cover 200 drives the second compartment cover 300 to rotate upward relative to the side wall of the main body 100. When the first compartment cover 200 rotates to its highest position, the stop block causes the first compartment cover 200 and the second compartment cover 300 to be mounted at a predetermined angle on the top of the main body 100.
[0063] When the first carriage cover 200 rises, the lower side of the convex ball 133 is pushed upward by the first carriage cover 200, thereby driving the moving plate 132 to move upward along the slide groove 131, so as to realize the function of shielding the space between the rear side of the first carriage cover 200, the second carriage cover 300 and the tail plate 130.
