Description

Technical Field

[0001] This application relates to the technical field of transportation, and particularly relates to a locking component, a door body mechanism, and a transportation device. Background Art

[0002] Transportation devices such as flying cars have relatively high requirements for the surface difference (i.e., flatness error) of the door body. However, the existing locking structures are basically implemented using door locks. The door lock has limited deviation correction ability for the surface difference, limited ability to overcome the back pressure of the sealing strip on the door body, and limited locking and deviation correction ability for the double-leaf door body without a fixed upper frame beam.

[0003] The reason for the above disadvantages is that the distance from the semi-locked state to the fully locked state of the door lock is generally 6 - 8 mm, and its deviation correction ability is limited. The door lock overcomes the reaction force of the sealing strip in the meshing direction of about 500 N. Due to the spatial structure limitation of the lock body, the sizes of the motor and the reduction gearbox cannot be made larger, resulting in limited output power, and ultimately limited ability to overcome the reaction force of the sealing strip. The poor deviation correction ability of the door lock is mainly due to the large gap between the lock tongue and the lock buckle, which is prone to mutual shaking. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0035] Transportation devices such as flying cars have relatively high requirements for the surface difference (i.e., flatness error) of the door body. However, the existing locking structures are basically implemented using door locks. The door locks have limited ability to correct the surface difference, limited ability to overcome the back pressure of the sealing strip on the door body, and limited ability to lock and correct the deviation of the double-leaf door body without a fixed upper frame beam.

[0036] The reason for the above-mentioned disadvantages is that the distance from the semi-locked state to the fully locked state of the door lock is generally 6 - 8 mm, and its deviation correction ability is limited. The door lock overcomes the reaction force of the sealing strip in the meshing direction of about 500 N. Due to the space structure limitation of the lock body, the sizes of the motor and the reduction gearbox cannot be made larger, resulting in limited output power, and ultimately limited ability to overcome the reaction force of the sealing strip. The poor deviation correction ability of the door lock is mainly due to the large gap between the locking tongue and the lock catch, which is prone to mutual shaking.

[0037] Therefore, this application proposes a locking assembly, a door body mechanism, and a transportation device, aiming to improve the deviation correction ability of the locking assembly and reduce the surface difference of the door body.

[0038] Refer to Figure 1 and Figure 2 , in an embodiment of this application, the door body mechanism is applied to the tail of a transportation device. The door body mechanism includes a first door body 2000, a second door body 3000, and the above-mentioned locking assembly 1000; the first door body 2000 and the second door body 3000 are rotatable door bodies arranged in a double-leaf opening manner; wherein:

[0039] The first door body 2000 is used for rotatably connecting with one side frame of the tail of the transportation device; the second door body 3000 is used for rotatably connecting with the other side frame of the tail of the transportation device.

[0040] In this embodiment, the first door body 2000 and the second door body 3000 can be opened and closed independently of each other, or can be opened and closed synchronously. Of course, only when the first door body 2000 and the second door body 3000 are both closed, the tail of the transportation device is completely closed.

[0041] Among them, the locking component 1000 can realize the connection and fixation between the first door body 2000 and the second door body 3000, as well as the connection and fixation between the first door body 2000, the second door body 3000 and the transportation device by means of plugging, clamping, buckling, etc. The locking component 1000 can be connected to the first door body 2000 and the second door body 3000 simultaneously when the first door body 2000 and the second door body 3000 are both rotated to the closed state, so that the first door body 2000 and the second door body 3000 maintain the current opening and closing angles relative to the transportation device. In this way, the locking of the first door body 2000 and the second door body 3000 is realized, so that they can stably maintain the current closed state during the driving process of the transportation device. For other locking forms of the locking component 1000, they can be flexibly set based on the above ideas and will not be listed one by one here.

[0042] It should be noted that the opening and closing actions of the first door body 2000 and the second door body 3000 can be realized manually or electrically, and the user can select the corresponding configuration according to the actual application scenario requirements. Among them, the door body mechanisms using manual or electric methods can realize the hovering of each door body at any angle through the corresponding self-locking mechanism, so as to further improve the convenience of passengers and goods entering and leaving the rear cabin.

[0043] For the above-mentioned locking component 1000, specifically, refer to Figure 1 、 Figure 2 and Figure 3, the locking assembly 1000 is applied to a transportation device, which at least includes an opening and closing first door body 2000 and second door body 3000; the locking assembly 1000 includes a limiting mechanism 1100 and a first hole seat 1200; the limiting mechanism 1100 includes a locking member 1110 and a driving device 1120, and the driving device 1120 is used to drive the locking member 1110 to move; the first hole seat 1200 is provided with a first limiting hole 1210; one of the first hole seat 1200 and the limiting mechanism 1100 is arranged on the first door body 2000, and the other is arranged on the second door body 3000; the driving device 1120 is used to drive the locking member 1110 to move towards the first hole seat 1200 when the first door body 2000 and the second door body 3000 are closed to each other, so that the locking member 1110 is in limiting cooperation with the first limiting hole 1210. Of course, when it is necessary to open the first door body 2000 and the second door body 3000, the driving device 1120 can be used to drive the locking member 1110 to move in a direction away from the first hole seat 1200, so as to release the limiting cooperation between the locking member 1110 and the first limiting hole 1210, and then the first door body 2000 and the second door body 3000 can be opened.

[0044] It can be understood that the first hole seat 1200 can be made of a corresponding material as needed. For example, according to the strength requirements for the first hole seat 1200, materials such as metal or plastic can be selected. In addition, the material of the first hole seat 1200 can also be selected according to requirements such as stiffness, and this embodiment does not limit this.

[0045] In addition, the locking member 1110 can be set as a locking pin, and the locking pin moves towards the first hole seat 1200 under the drive of the driving device 1120, so as to realize the pin-hole limiting cooperation between the locking pin and the first limiting hole 1210. Among them, the surface difference between the first door body 2000 and the second door body 3000 can be adjusted by setting locking pins and first limiting holes 1210 of different sizes to achieve clearance fit or tight fit, so as to meet the actual matching requirements between the first door body 2000 and the second door body 3000.

[0046] In this embodiment, by setting the locking assembly 1000 to include a limiting mechanism 1100 and a first hole seat 1200, the limiting mechanism 1100 includes a driving device 1120 and a locking member 1110, and the first hole seat 1200 is provided with a first limiting hole 1210; by arranging one of the limiting mechanism 1100 and the first hole seat 1200 on the first door body 2000 and the other on the second door body 3000, and using the driving mechanism to drive the locking member 1110 to move towards the first hole seat 1200 when the first door body 2000 and the second door body 3000 are closed, so that the locking member 1110 is in limiting cooperation with the first limiting hole 1210, thereby ensuring that the surface difference between the first door body 2000 and the second door body 3000 is within a preset error range.

[0047] Compared with the existing door locks, the locking component 1000 achieves a stronger deviation correction effect through the limiting cooperation between the locking member 1110 and the first limiting hole 1210. It not only locks the opened door, but also can effectively reduce the deviation caused by the assembly and deformation of the door body. The limiting cooperation between the locking member 1110 and the first limiting hole 1210 also prevents the first door body 2000 and the second door body 3000 from being misaligned and distorted, improves the stiffness of the double-leaf door, and enhances the durability and reliability of the door body.

[0048] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 4 , a guiding structure 1220 is provided on one side of the first hole seat 1200 facing the locking member 1110. The guiding structure 1220 is used to guide the locking member 1110 to move towards the first limiting hole 1210 when the locking member 1110 moves towards the first hole seat 1200. By providing the guiding structure 1220 on the first hole seat 1200, when the locking member 1110 moves towards the first hole seat 1200, even if there is a large surface difference between the first door body 2000 and the second door body 3000, the guiding structure 1220 can still guide the locking member 1110 to move towards the first limiting hole 1210, so that the limiting cooperation between the locking member 1110 and the first limiting hole 1210 is achieved, thereby improving the deviation correction ability of the locking component 1000 for different door bodies with a large surface difference.

[0049] In one embodiment, referring to Figure 1 and Figure 3 , the above-mentioned guiding structure 1220 can be set to include an opening 1221 on the side facing the locking member 1110. The aperture of the opening 1221 gradually decreases in the direction away from the limiting mechanism 1100, and the opening 1221 is communicated with the first limiting hole 1210.

[0050] In this way, in this embodiment, when there is a large surface difference between the first door body 2000 and the second door body 3000, during the movement of the locking member 1110 towards the first limiting hole 1210, one side of the locking member 1110 in the first direction will contact the hole wall of the opening 1221. Since the aperture of the opening 1221 gradually decreases in the first direction, the locking member 1110 will move towards the direction of the first limiting hole 1210 under the combined action of the driving force of the driving device 1120 and the extrusion reaction force of the hole wall of the opening 1221. During the movement of the locking member 1110 along the hole wall of the opening 1221 towards the first limiting hole 1210, the surface difference between the first door body 2000 and the second door body 3000 decreases, thereby achieving the deviation correction effect of the locking component 1000.

[0051] It should be noted that the prerequisite for the locking component 1000 to achieve deviation correction is that the locking member 1110 can smoothly move into the first limiting hole 1210 to achieve limiting cooperation. Therefore, when there is a large surface difference between the first door body 2000 and the second door body 3000, the guiding function of the guiding structure 1220 plays a key role in guiding the locking member 1110 to move towards the first limiting hole 1210. Therefore, the range within which the guiding structure 1220 can achieve guiding determines the size of the deviation correction range of the locking component 1000. Therefore, on the premise of ensuring the normal operation of the first door body 2000 and the first door body 2000, and the structural strength of the first hole seat 1200, the aperture of the opening 1221 facing the locking member 1110 can be appropriately increased to increase the maximum surface difference range within which the locking component 1000 can correct the deviation of the first door body 2000 and the second door body 3000.

[0052] To solve the problem that the sliding friction between the locking member 1110 and the guiding structure 1220 during deviation correction causes significant wear on the guiding structure 1220, in one embodiment, referring to Figure 1 and Figure 4 , the opening 1221 is set as a tapered hole, and a chamfer 1111 is provided on the side of the locking member 1110 facing the first hole seat 1200. The difference between the taper of the chamfer 1111 and the taper of the tapered hole is within a preset error range. In this way, the taper of the chamfer 1111 matches the taper of the tapered hole, so that the contact area between the locking member 1110 and the opening 1221 of the guiding structure 1220 increases during contact, reducing the local stress on the hole wall of the opening 1221, and thus slowing down the wear of the hole wall of the opening 1221 by the locking member 1110 during deviation correction.

[0053] In another embodiment, a fillet can also be provided on the side of the locking member 1110 facing the first hole seat 1200, which can also increase the contact area between the locking member 1110 and the hole wall of the opening 1221, reduce the local stress on the hole wall of the opening 1221, and thus slow down the wear of the hole wall of the opening 1221 by the locking member 1110 during deviation correction.

[0054] In the above embodiment of the first limiting hole 1210, the problem of water ingress is likely to occur on the side of the first limiting hole 1210 facing away from the locking member 1110. To solve this problem, in one embodiment, the first limiting hole 1210 can be set as a blind hole, thereby preventing the side of the first limiting hole 1210 facing away from the locking member 1110 from communicating with the outside, eliminating the hidden danger of water ingress from the side of the first limiting hole 1210 facing away from the locking member 1110, so as to meet the sealing and waterproof requirements for the first limiting hole 1210.

[0055] In another embodiment, the first limiting hole 1210 can also be set as a through hole. The locking assembly 1000 includes a cover that is integrally formed separately from the first hole seat 1200. The cover plugs the side of the first limiting hole 1210 facing away from the limiting mechanism 1100, thereby also avoiding the communication between the side of the first limiting hole 1210 facing away from the locking member 1110 and the outside world, meeting the sealing and waterproof requirements for the first limiting hole 1210.

[0056] In one embodiment, referring to Figure 1 and Figure 3 , the locking assembly 1000 further includes a plurality of bushings 1300 and a plurality of fasteners; a plurality of mounting holes 1230 are provided on the first hole seat 1200, and bushings 1300 are embedded in the mounting holes. Among them, the structural strength of the bushing 1300 is greater than that of the first hole seat 1200; the fasteners pass through the bushings 1300 and lock the first hole seat 1200 to another door body. The bushing 1300 is used to prevent the fasteners from directly contacting the mounting holes of the first hole seat 1200, especially to prevent the fasteners from directly contacting the first hole seat 1200 during installation and fastening and crushing the first hole seat 1200.

[0057] Since bushings 1300 are embedded in the mounting holes of the first hole seat 1200, the wear directly caused by the fasteners to the first hole seat 1200 during the installation and disassembly process is changed to the wear of the fasteners on the bushings 1300, thereby reducing the wear of the mounting holes; in addition, since a plurality of holes such as the first limiting hole 1210 and mounting holes are provided on the first hole seat 1200, the structural strength of the first hole seat 1200 may be affected. Therefore, there may be a risk of crushing the first hole seat 1200 during the installation process if the fasteners are directly installed in the mounting holes. Therefore, by installing the fasteners in the bushings 1300 with a structural strength greater than that of the first hole seat 1200, the structural safety of the first hole seat 1200 is protected, and thus the service life of the first hole seat 1200 is ensured.

[0058] Among them, as an optional embodiment, the fasteners can be set as threaded connectors or can also be set as fasteners such as rivets. In this application, the fasteners can be set as threaded connectors to facilitate the repeated installation and disassembly of the first hole seat 1200.

[0059] For the bushing 1300, it can be set as a metal bushing to provide sufficient structural strength to protect the first hole seat 1200. For the material of the first hole seat 1200, since the bushing 1300 protects the first hole seat 1200, the material selection range of the first hole seat 1200 is relatively wide. The material of the first hole seat 1200 can be selected from one of a variety of materials such as metal or plastic, and the specific material can be selected according to the actual requirements of stiffness and strength.

[0060] In one embodiment, referring to Figure 1 and Figure 5 , the driving device 1120 includes a motor and a gearbox; the rotating shaft of the motor is connected to the input end of the gearbox, the output end of the gearbox is drivingly connected to the locking member 1110, and the output end of the gearbox is used to drive the locking member 1110 to move towards the first hole seat 1200, so that the locking member 1110 is in limiting cooperation with the first limiting hole 1210.

[0061] Wherein, the gearbox is used to convert the relatively high rotational speed output by the rotating shaft of the motor into a relatively low rotational speed, so as to meet the precise control requirement for the moving distance of the locking member 1110, avoid the lack of rotational control precision of the motor resulting in the inability to precisely drive the locking member 1110, and achieve precise control of the insertion of the locking member 1110.

[0062] The connection between the rotating shaft of the motor and the input end of the gearbox can be understood as that the rotating shaft of the motor is directly inserted into the input shaft of the gearbox, or the rotating shaft of the motor is connected to the input end of the gearbox through a coupling.

[0063] The driving connection between the gearbox and the locking member 1110 can be understood as that since the rotation output by the gearbox needs to be converted into the movement of the locking member 1110, corresponding transmission mechanisms can be added to achieve this conversion, such as a lead screw-nut mechanism, a gear-rack mechanism, a pulley and belt mechanism, etc. The specific transmission mechanism to be selected can be determined according to actual installation needs, and this embodiment does not limit this.

[0064] To prevent the limiting mechanism 1100 from being damaged due to being easily impacted by the outside, in one embodiment, referring to Figure 5 and Figure 6 , a first cavity is provided inside the side frame of the first door body 2000, and the driving device 1120 is installed in the first cavity. The first cavity is used to minimize the influence of external impact on the driving device 1120 and provide protection for the driving device 1120; wherein, a first through hole for the locking member 1110 to pass through is provided on the cavity wall of the first cavity facing the first hole seat 1200, and the first hole seat 1200 is installed on the side frame of the second door body 3000; the driving device 1120 is used to drive the locking member 1110 to pass through the first through hole and move towards the first hole seat 1200, so as to ensure both protection for the driving device 1120 and the normal driving effect of the driving device 1120 on the locking member 1110.

[0065] In one embodiment, referring to Figure 1 and Figure 4, the motor includes a motor body 1121 and a motor end cover 1122, the transmission includes a transmission body and a transmission cover 1123, and the driving device 1120 further includes a housing 1124; the motor end cover 1122 is sleeved on one end of the motor body 1121 facing away from the rotating shaft, and the motor end cover 1122 is used to enclose and protect the internal structure of the motor body 1121, preventing foreign objects from entering the inside of the motor body 1121 and affecting the normal operation of the motor body 1121; the housing 1124 is sleeved on the outside of the locking member 1110, and the housing 1124 is used to protect the locking member 1110, preventing the locking member 1110 from being affected by external impacts and the like when in the unmoved state; a third through hole for the locking member 1110 to pass through is provided on one side of the housing 1124 facing the first hole seat 1200, which is used to ensure that the locking member 1110 can move normally towards the first limiting hole 1210; the transmission cover 1123 is sleeved on the outside of the transmission body, and the transmission cover 1123 is used to enclose and protect the internal structure of the transmission body, preventing foreign objects from entering the inside of the transmission body and affecting the normal operation of the transmission body.

[0066] In one embodiment, referring to Figure 3 and Figure 7 , the transportation device has a rear cabin, and the door body mechanism further includes a top cover door 4000, and the top cover door 4000 is rotatably connected to the upper side of the rear cabin around a horizontal axis; the first door body 2000 is rotatably connected to the lower left side of the rear cabin around a first axis, and the first axis has a vertical component; the second door body 3000 is rotatably connected to the lower right side of the rear cabin around a second axis, and the second axis has a vertical component; when the top cover door 4000, the first door body 2000, and the second door body 3000 are all rotated to the closed state, the top cover door 4000, the first door body 2000, and the second door body 3000 are closed pairwise and cover the rear cabin; the top cover door 4000 is provided with a connection structure; when the top cover door 4000, the first door body 2000, and the second door body 3000 are all rotated to the closed state, the locking member 1110 in the locking assembly 1000 passes through the connection structure and is in limiting cooperation with the first limiting hole 1210 in the locking assembly 1000, and the locking member 1110 is used to prevent the connection structure from moving along the opening direction of the top cover door 4000.

[0067] Specifically, when the top cover door 4000 is closed, the connecting structure should be located between the locking member 1110 and the first hole seat 1200. The connecting structure can be set as a through-hole structure or a snap structure. Taking the through-hole structure as an example, the locking member 1110 should pass through its through-hole part. Taking the snap structure as an example, the locking member 1110 should pass through the concave side of its buckle body part. In this way, when the locking member 1110 passes through the connecting structure and is in limit fit with the first limit hole 1210, the locking member 1110 will form a limiting effect on the connecting structure in the vertical direction. When the top cover door 4000 rotates upward, the connecting structure will abut against the locking member 1110, making the top cover door 4000 unable to rotate further. In this way, the connection and fixation between the first door body 2000, the second door body 3000 and the top cover door 4000 can be realized, preventing the top cover door 4000 from moving upward in the closed state, enhancing the locking tightness between the top cover door 4000, the first door body 2000 and the second door body 3000, and further improving the locking stability.

[0068] In this embodiment, when the top cover door 4000, the first door body 2000 and the second door body 3000 all rotate to the closed state, the left and right edges of the top cover door 4000 are in contact with the transportation equipment, the lower edge of the top cover door 4000 is in contact with the upper edges of the first door body 2000 and the second door body 3000, the lower edge of the first door body 2000 is in contact with the transportation equipment, the right edge of the first door body 2000 is in contact with the left edge of the second door body 3000, and the lower edge of the second door body 3000 is in contact with the transportation equipment. At this time, the top cover door 4000, the first door body 2000 and the second door body 3000 form a continuous cover structure, which can cover the rear cabin and play corresponding roles such as isolation and protection.

[0069] When the passengers and goods in the rear cabin need to be transferred outside the transportation equipment, the locking of the locking assembly 1000 on each door body can be released first, and then the top cover door 4000, the first door body 2000 and the second door body 3000 can be opened. During the opening process of the top cover door 4000, the first door body 2000 and the second door body 3000, due to the existence of the top cover door 4000, the process of the top cover door 4000 rotating upward to open is equivalent to opening a part of the top structure of the rear cabin upward. In this way, the height limit of the transportation equipment is relieved to a certain extent. Coupled with the action of the first door body 2000 rotating leftward to open below the left lower part of the top cover door 4000 and the action of the second door body 3000 rotating rightward to open below the right lower part of the top cover door 4000, a larger opening angle of the door body mechanism can be achieved, providing a larger access space for the rear cabin, making it more convenient for passengers and large-sized goods to enter and exit the rear cabin.

[0070] It can be seen that the door body mechanism provided in this embodiment adopts a three - door form in which the top cover door 4000, the first door body 2000, and the second door body 3000 cooperate with each other. There is no need to set a cross - beam structure at the connection part between the three door bodies. This three - door form can provide a structural basis for making up for the deficiencies of traditional single - door and double - door forms and relieving the restriction of the height dimension of transportation equipment on the access space of the rear cabin. Without changing the internal space of the original rear cabin, a larger door opening angle can be achieved, thereby increasing the access space of the rear cabin, making it more convenient for passengers and large - sized goods to enter and exit the rear cabin, and enabling the rear cabin to achieve convenient loading of goods and personnel; when the top cover door 4000, the first door body 2000, and the second door body 3000 are closed, the locking component 1000 can also be used to lock between each door body and between each door body and the transportation equipment, so that each door body can maintain the current closed state during driving, thus stably covering the rear cabin and playing corresponding isolation and protection roles.

[0071] In one embodiment, referring to Figure 7 , the upper side of the top cover door 4000 is rotatably connected to the upper side of the rear cabin around the third axis. The third axis is parallel to the left - right direction of the transportation equipment, and the third axis is located above the front of the first door body 2000 and the second door body 3000; when the top cover door 4000 rotates to the closed state, the top cover door 4000 is used to be erected on the transportation equipment, and the lower side of the top cover door 4000 is used to abut against the upper sides of the first door body 2000 and the second door body 3000.

[0072] This embodiment further defines the relative positions between the top cover door 4000, the first door body 2000, and the second door body 3000; taking the normal driving direction of the transportation equipment as the front - rear direction, when the third axis around which the top cover door 4000 rotates with respect to the transportation equipment is set above the front of the first door body 2000 and the second door body 3000, it can be ensured that when the top cover door 4000 rotates upward to open, it can open the top structure of the rear cabin between the third axis and the first door body 2000 and the second door body 3000 upward. In this way, the height restriction of the part between the third axis and the first door body 2000 and the second door body 3000 can be relieved, a larger opening angle of the door body mechanism can be achieved, and the rear cabin 11 can obtain a larger access space.

[0073] At the same time, based on the above - mentioned structural settings, the top cover door 4000 is inclined in the closed state. At this time, the top cover door 4000 can be erected on the part of the transportation equipment located at the edge of the rear cabin. That is, the part of the transportation equipment located at the edge of the rear cabin can form a certain supporting effect on the top cover door 4000 in the vertical direction. In this way, the fitting stability between the top cover door 4000 and the transportation equipment can be improved under the action of gravity, so that the top cover door 4000, the first door body 2000, and the second door body 3000 can stably maintain the current closed state during driving.

[0074] In one embodiment, the connection structure includes a second hole seat and a flexible collar; the second hole seat is connected to the top cover door 4000, the second hole seat is provided with a second limiting hole, the outer ring of the flexible collar fits against the hole wall of the second limiting hole, and the locking member 1110 is used to pass through the inner hole of the flexible collar and be in limiting cooperation with the first limiting hole 1210.

[0075] Specifically, when the locking member 1110 passes through the second limiting hole and is in limiting cooperation with the first limiting hole 1210, if the top cover door 4000 rotates upward, the locking member 1110 will abut against the second hole seat to prevent the top cover door 4000 from continuing to rotate upward, thereby achieving the limiting effect on the top cover door 4000. By providing a flexible collar in the second limiting hole, a buffering effect can be exerted on the locking member 1110, which can avoid the rigid collision between the locking member 1110 and the hole wall of the second limiting hole and cause wear, thereby prolonging the service life of the locking member 1110 and the second hole seat; among them, the flexible collar can be made of flexible materials such as rubber, silica gel, and plastic.

[0076] In one embodiment, the connection structure is movably connected to the top cover door 4000, and the connection structure is used to be locked to the top cover door 4000 through a threaded fastener. Specifically, the connection structure can be adjusted in position on the top cover door 4000 by providing waist-shaped holes, and can be fixed by threaded fasteners such as bolts after the adjustment is in place. Based on the above settings, the position of the connection structure can be flexibly and conveniently adjusted according to the actual positions of the locking member 1110 and the first hole seat 1200 to ensure that the locking member 1110 can accurately pass through the connection structure and be in limiting cooperation with the first limiting hole 1210, thereby improving the matching accuracy.

[0077] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 8 , for the above door body mechanism, the door body mechanism may further include a first door lock 5000 and a second door lock 6000. The first door lock 5000 includes a first lock tongue 5100 and a first lock catch 5200, and the second door lock 6000 includes a second lock tongue 6100 and a second lock catch 6200; the first lock tongue 5100 is arranged at the bottom of the first door body 2000, and the second lock tongue 6100 is arranged at the bottom of the second door body 3000; the first lock catch 5200 and the second lock catch 6200 are both arranged on the bottom surface of the tail of the transportation device; the first lock tongue 5100 is used to lock with the first lock catch 5200 when the first door body 2000 rotates to the closed state; the second lock tongue 6100 is used to lock with the second lock catch 6200 when the second door body 3000 rotates to the closed state.

[0078] In this embodiment, through the arrangement of the first door lock 5000 and the second door lock 6000, when the locking assembly 1000 bears the back pressure from the frame at the tail of the transportation device and the sealing reaction force exerted by the sealing strip, the first door lock 5000 and the second door lock 6000 can jointly share this part of the acting force for the locking assembly 1000, avoiding the locking assembly 1000 from bearing excessive loads. In addition, the arrangement of the first door lock 5000 and the second door lock 6000 can also provide locking and fixing for the lower frames of the first door body 2000 and the second door body 3000, so as to jointly perform locking and fixing with the locking assembly 1000, improving the locking reliability of the first door body 2000 and the second door body 3000. And the first door lock 5000 and the second door lock 6000 can also correct the surface difference between the first door body 2000 and the second door body 3000 to a certain extent, so as to jointly ensure the consistency of the surface difference between the first door body 2000 and the second door body 3000 with the locking assembly 1000.

[0079] In one embodiment, referring to Figure 1 , Figure 2 and Figure 8 , for the embodiment in which the above-mentioned door body mechanism includes three door bodies, namely the first door body 2000, the second door body 3000, and the top cover door 4000, to meet the sealing requirements of the door body mechanism, the door body mechanism further includes a first sealing strip (not shown in the figure), a second sealing strip (not shown in the figure), and a third sealing strip (not shown in the figure). The first sealing strip is installed along the upper frame, right frame, and lower frame of the first door body 2000, the second sealing strip is installed along the upper frame, left frame, and lower frame of the second door body 3000, and the third sealing strip is installed along the left frame, right frame, and lower frame of the top cover door 4000. When the first door body 2000, the second door body 3000, and the top cover door 4000 all rotate to the closed state, the first door body 2000, the second door body 3000, and the top cover door 4000 respectively abut against the first sealing strip, the second sealing strip, and the third sealing strip. At this time, the gaps between the first door body 2000, the second door body 3000, and the top cover door 4000 are eliminated by each sealing strip, achieving the sealing effect.

[0080] In one embodiment, referring to Figure 2 and Figure 5 , for the above-mentioned embodiment provided with the first door lock 5000 and the second door lock 6000 or the embodiment provided with the first sealing strip, the second sealing strip, and the third sealing strip, one of the first hole seat 1200 and the limiting mechanism 1100 can be arranged on the upper side part of the right frame of the first door body 2000, and the other can be arranged on the upper side part of the left frame of the second door body 3000.

[0081] In this embodiment, for the embodiment provided with the first door lock 5000 and the second door lock 6000, when the first lock tongue 5100 is arranged at the bottom of the first door body 2000 and the first lock catch 5200 is arranged at the lower side frame of the tail of the transportation device: the left side frame of the first door body 2000 is rotationally connected to the side frame of the tail of the transportation device, and the lower side frame of the first door body 2000 can be locked and fixed by the first door lock 5000. At this time, the position where the first door body 2000 is most likely to be misaligned and distorted is the upper right side frame. Similarly, the right side frame of the second door body 3000 is rotationally connected to the side frame of the tail of the transportation device, and the lower side frame of the second door body 3000 can be locked and fixed by the second door lock 6000. At this time, the position where the second door body 3000 is most likely to be misaligned and distorted is the upper left side frame. Therefore, arranging the first hole seat 1200 and the limiting mechanism 1100 at the upper side parts of the side frames of the first door body 2000 and the second door body 3000 can improve the evenness of the locking and fixing effects on each part of the first door body 2000 and the second door body 3000, thereby improving the locking reliability of the first door body 2000 and the second door body 3000.

[0082] For the embodiment provided with the first sealing strip, the second sealing strip, and the third sealing strip, in the case of a three-door form with a top cover door 4000, at this time, neither the first door body 2000 nor the second door body 3000 has a fixed upper frame beam to abut against. The positions where the first door body 2000 and the second door body 3000 are most likely to be misaligned and distorted are also at the upper side parts of their respective side frames. Therefore, arranging the first hole seat 1200 and the limiting mechanism 1100 at the upper side parts of the side frames of the first door body 2000 and the second door body 3000 can also improve the evenness of the locking and fixing effects on each part of the first door body 2000 and the second door body 3000, thereby improving the locking reliability of the first door body 2000 and the second door body 3000.
