Description

Technical Field

[0001] The present invention relates to the technical field of logistics equipment, and in particular to a loading and unloading structure of an express delivery vehicle and a control method thereof. Background Art

[0002] As a key product in unmanned logistics, unmanned delivery vehicles are the vehicles for point-to-point transportation of goods. In real life, they are mainly used to deliver parcels from distribution centers to consignees, thereby solving the problem that the terminal delivery market requires a large amount of manpower and material resources.

[0003] At present, the existing unmanned delivery vehicles on the market usually include a vehicle and a cage rack. The cage rack is installed in the cargo area of ​​the vehicle, and the cage rack is used to load the cage. In addition, in order to facilitate the loading and unloading of the cage, the cage is usually loaded with external auxiliary equipment, such as using a manipulator to grab and transfer the cage, or using an integrated loading and unloading device installed on the unmanned delivery vehicle to realize the movement of the cage rack, so as to complete the loading and unloading of the cage. Although the above structures can realize the loading and unloading of cage boxes, the method of loading and unloading with the help of external auxiliary equipment requires additional operating space and is relatively costly. Although the method of loading and unloading with an integrated loading and unloading device can save space, it usually stacks the translation component and the flip component together, such as installing the translation component on a vehicle, installing the flip component on the translation component, and then connecting the flip component to the cage frame, and requiring the configuration of more linkage structures, resulting in a more complex overall structure. In addition, for the above complex structure, more control structures need to be configured to ensure its safe and stable operation. There are problems such as complex operation and inconvenient use, which is not conducive to large-scale promotion and use. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Fig. 9 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0019] Figure 1 A structural diagram of an embodiment of a loading and unloading structure for an express delivery vehicle of the present invention; Figure 2 It is a schematic diagram of the installation of a flip assembly, a translation assembly, a vertical monitor, a horizontal monitor, a forward monitor and a rearward monitor on a vehicle according to a preferred embodiment of the present invention; Figure 3 FIG. 1 is a structural diagram of a cage frame of a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, the express delivery vehicle loading and unloading structure provided in this embodiment includes: a vehicle 1, a cage frame 2, a translation assembly 3, a flip assembly 4, a vertical monitor 5, a horizontal monitor 6, a forward monitor 7 and a backward monitor 8.

[0020] Specifically, the vehicle 1 and the cage frame 2 are separate structures, so that the cage body can translate or flip relative to the vehicle 1. At this time, the cage body is installed on the loading area of ​​the vehicle 1, and a translation assembly 3 and a flip assembly 4 independently installed on the vehicle 1 are arranged between the cage frame 2 and the vehicle 1, so that the installation carriers of the translation assembly 3 and the flip assembly 4 are both the vehicle 1, avoiding the problem of complex structure caused by the need for stacking arrangement between the two, and at the same time, it is also convenient to realize operation control.

[0021] Specifically, the vehicle 1 is also provided with a number of trigger structures. At this time, the translation assembly 3 is installed on the front middle part of the loading area of ​​the vehicle 1. The translation assembly 3 includes a pull rod 31. The pull rod 31 moves back and forth along its central axis, providing power for the subsequent translation of the cage frame 2 along the central axis of the vehicle 1 by the pull rod 31 of the translation assembly 3. In addition, the flip assembly 4 is installed at the rear part of the loading area of ​​the vehicle 1. At the same time, the flip assembly 4 includes a flip plate 41, and the flip plate 41 is hinged to the rear part of the vehicle 1, providing power for the subsequent flip plate 41 of the flip assembly 4 to drive the cage frame 2 to flip. In addition, a sleeve 21 that is engaged with the pull rod 31 and a card plate 22 that is engaged with the flip plate 41 are provided at the bottom of the cage frame 2. When in use, if the pull rod 31 moves, the pull rod 31 is engaged with the sleeve 21 and the flip plate 41 is separated from the card plate 22; if the flip plate 41 flips, the flip plate 41 is engaged with the card plate 22 and the pull rod 31 is separated from the sleeve 21, thereby realizing the selective action of the flip component 4 and the translation component 3, so that the flipping movement and translation movement of the cage frame 2 will not interfere with each other, which can meet the use requirements of the translation component 3 and the flip component 4 being separately installed on the vehicle 1 and moving independently, avoiding the structural complexity caused by the stacking arrangement, and also providing convenience for triggering the corresponding function keys according to different operating states to realize one-key operation of loading and unloading, thereby improving the convenience of operation and facilitating large-scale promotion and use.

[0022] Specifically, the trigger structures arranged on the vehicle 1 include a vertical monitor 5, a horizontal monitor 6, a forward monitor 7 and a backward monitor 8. When assembled, the vertical monitor 5 is arranged below the rear of the vehicle 1 to monitor whether the cage frame 2 is in a vertical state. The horizontal monitor 6 is arranged at the rear of the loading area of ​​the vehicle 1 and below the flip plate 41 to monitor whether the cage frame 2 is flipped up to the right position. The forward monitor 7 is arranged at the front of the loading area of ​​the vehicle 1 to monitor whether the cage frame 2 is moved forward to the right position. The backward monitor 8 is arranged at the rear of the loading area of ​​the vehicle 1 and at the maximum outward travel of the pull rod 31 to monitor whether the cage frame 2 is moved backward to the right position. When in use, the cage frame 2 contacts or moves away from the vertical monitor 5. When the vertical monitor 5 is triggered by the cage frame 2, it is judged that the cage frame 2 is in a vertical state. The flip plate 41 contacts or moves away from the horizontal monitor 6. When the flip plate 41 contacts the horizontal monitor 6, it is judged that the cage frame 2 is in a horizontal state. At the same time, the bottom of the cage frame 2 is provided with a forward trigger plate 23 that contacts or moves away from the forward monitor 7 and a rearward trigger plate that contacts or moves away from the rearward monitor 8, and the rearward trigger plate can also be installed on the pull rod 31. When the forward trigger plate 23 contacts the forward monitor 7, it is judged that the cage frame 2 has moved forward to the right position and is stably placed in the loading area of ​​the vehicle 1. When the rearward trigger plate contacts the rearward monitor 8, it is judged that the cage frame 2 has moved backward to the right position. At this time, the cage frame 2 can be turned down or moved forward to realize the monitoring of different spatial states of the cage frame 2. Preferably, the vertical monitor 5, the horizontal monitor 6, the forward monitor 7 and the rearward monitor 8 can all use travel switches, which can be directly purchased on the market and installed. The specific structure is not repeated here.

[0023] In addition, the present embodiment also provides a control method for the loading and unloading structure of an express delivery vehicle. The control method uses the above-mentioned loading and unloading structure of the express delivery vehicle to achieve the purpose of controlling the triggering of the loading function key or the unloading function key, thereby satisfying the one-key operation of loading and unloading and improving the convenience of operation. At this time, the loading function key includes three modes: flipping up, moving forward and not moving, and the unloading function key includes three modes: not moving, flipping down and moving backward. When controlling, it is necessary to first determine the monitoring triggering status of the vertical monitor 5, the horizontal monitor 6, the forward monitor 7 and the backward monitor 8, and then determine the spatial state of the cage frame 2 according to the monitoring triggering status, and finally trigger one of the three modes corresponding to the loading function key and one of the three modes corresponding to the unloading function key according to the spatial state of the cage frame 2, so as to realize the control triggering of the loading function and the unloading function key, thereby satisfying the one-key operation requirements of loading and unloading.

[0024] Figure 4 The figure is a schematic diagram of the corresponding relationship between the monitoring trigger state, the spatial state and the trigger mode of the control method of the express delivery vehicle loading and unloading structure of the present invention. Figure 4As shown, in the control process, the vertical monitor 5 is set to letter A, untriggered is represented by A0, and untriggered is represented by A1; the horizontal monitor 6 is set to letter B, untriggered is represented by B0, and untriggered is represented by B1; the rearward monitor 8 is set to letter C, untriggered is represented by C0, and untriggered is represented by C1; the forward monitor 7 is set to letter D, untriggered is represented by D0, and untriggered is represented by D1. In addition, the corresponding relationships between the monitoring triggering states of the vertical monitor 5, the horizontal monitor 6, the forward monitor 7, and the rearward monitor 8, the spatial state of the cage frame 2, and the triggering modes of the loading function key and the unloading function key include the following: The first one is that when the monitoring trigger state is that the vertical monitor 5 triggers A1, the horizontal monitor 6 does not trigger B0, the forward monitor 7 does not trigger D0, and the backward monitor 8 triggers C1, the spatial state of the cage frame 2 is judged to be a vertical state, and the flipping mode of the triggering loading function key and the stationary mode of the triggering unloading function key are controlled. At this time, the cage frame 2 can only realize loading.

[0025] The second type is that when the monitoring trigger state is that the vertical monitor 5 is not triggered A0, the horizontal monitor 6 is not triggered B0, the forward monitor 7 is not triggered D0, and the backward monitor 8 is triggered C1, the spatial state of the cage frame 2 is judged to be a tilted state, and the upturn mode of the loading function key is triggered or the downturn mode of the unloading function key is triggered. At this time, the cage frame 2 can realize both loading and unloading. It is worth pointing out that if the previous operation is loading, loading will continue in this case, and if the previous operation is unloading, unloading will continue in this case, which is convenient for control and meets the use requirements of one-key loading and unloading.

[0026] The third type is that when the monitoring trigger state is that the vertical monitor 5 is not triggered A0, the horizontal monitor 6 is triggered B1, the forward movement monitor 7 is not triggered D0, and the backward movement monitor 8 is triggered C1, the spatial state of the cage frame 2 is judged to be the backward movement state, and the forward movement mode of the loading function key is triggered or the downward flip mode of the unloading function key is triggered. At this time, the cage frame 2 can realize both loading and unloading. It is worth pointing out that if the previous operation is loading, loading will continue in this case, and if the previous operation is unloading, unloading will continue in this case, which is also convenient for control and meets the use requirements of one-key loading and unloading.

[0027] The fourth type is that when the monitoring trigger state is that the vertical monitor 5 is not triggered A0, the horizontal monitor 6 is triggered B1, the forward movement monitor 7 is not triggered D0, and the backward movement monitor 8 is not triggered C0, the spatial state of the cage frame 2 is judged to be the intermediate state of movement, and the forward movement mode of the loading function key is triggered or the backward movement mode of the unloading function key is triggered. At this time, the cage frame 2 can realize both loading and unloading. It is worth pointing out that if the previous operation is loading, loading will continue to be realized in this case, and if the previous operation is unloading, unloading will continue to be realized in this case, which is also convenient for control and meets the use requirements of one-key loading and unloading.

[0028] The fifth type, when the monitoring trigger state is that the vertical monitor 5 is not triggered A0, the horizontal monitor 6 is triggered B1, the forward movement monitor 7 is triggered D1, and the backward movement monitor 8 is not triggered C0, then the spatial state of the cage frame 2 is judged to be the forward movement in place state, and the stationary mode of the loading function key is triggered or the backward movement mode of the unloading function key is triggered. At this time, the cage frame 2 can only realize unloading.

[0029] More specifically, if the monitoring trigger state appears other than the first, second, third, fourth and fifth monitoring trigger states mentioned above, the spatial state of the cage frame 2 is judged to be unknown, and an alarm is issued, and the loading function key and the unloading function key are triggered at the same time. The fixed mode, the loading and unloading structure of the express delivery vehicle enters the safety mode, thereby improving the safety of operation.

[0030] Figure 5 FIG. 1 is a schematic diagram of the coordination of the flip assembly and the cage frame of a preferred embodiment of the present invention. Figures 1 to 3 as well as Figure 5As shown, the flip assembly 4 for driving the cage frame 2 to flip on the vehicle 1 also includes a rotating shaft support 42 and a flip push rod 43. The rotating shaft support 42 is installed at the rear of the vehicle 1, and one end of the flip plate 41 is hinged on the rotating shaft support 42, that is, the rotating shaft support 42 provides a mounting carrier for the hinge of the flip plate 41 on the vehicle 1. At the same time, the other end of the flip plate 41 is hinged to the push rod shaft of the flip push rod 43, so that the flip push rod 43 can push the flip plate 41 to flip on the rear plate of the vehicle 1, providing power for the subsequent flipping of the cage frame 2 through the flip plate 41. At the same time, the flip push rod 43 is hinged to the vehicle 1, realizing the independent installation of the flip push rod 43 on the vehicle 1, avoiding the problem of interference between its installation and movement and the translation assembly 3. The front card plate 221 and the rear card plate 222 are arranged at the bottom of the cage frame 2 at intervals and are respectively connected to or separated from the front card slot 411 and the rear card slot 412. When in use, if the cage frame 2 needs to be turned over, the front card plate 221 is inserted into the front card slot 411, and the rear card plate 222 is inserted into the rear card slot 412, so as to realize the connection between the cage frame 2 and the flip plate 41, so that the flip plate 41 can drive the cage frame 2 to turn over, thereby meeting the use requirements of loading and unloading.

[0031] Figure 6 FIG. 1 is a schematic diagram of the cooperation between the translation assembly and the cage frame of a preferred embodiment of the present invention. Figures 1 to 3 as well as Figure 6 As shown, the translation assembly 3 also includes a translation push rod 32 and a support plate 33. The translation push rod 32 is installed on the vehicle 1 and is located between the vehicle head and the flip assembly 4, so as to realize the utilization of the space between the flip assembly 4 and the vehicle head. In addition, the translation push rod 32 is arranged along the central axis of the vehicle 1, and the pull rod 31 is installed on the push rod shaft of the translation push rod 32, so that the push rod shaft of the translation push rod 32 can drive the pull rod 31 to move back and forth along the central axis of the vehicle 1, providing power for the subsequent forward and backward movement of the cage frame 2. In addition, the support plate 33 is installed on the vehicle 1 and arranged parallel to the push rod shaft of the translation push rod 32, so that the arrangement direction of the support plate 33 is consistent with the movement direction of the translation push rod 32, and the pull rod 31 is slidably arranged on the support plate 33, and the support plate 33 provides support and guidance for the pull rod 31, thereby improving the stability of the pull rod 31 when moving. Preferably, a pulley is provided at the end of the pull rod 31, and the pull rod 31 contacts the support plate 33 via the pulley, thereby effectively reducing the wear of the pull rod 31 and the support plate 33 and extending the service life of various related structures.

[0032] Figure 7FIG. 1 is a schematic diagram of the cooperation between a wheel set and a grooved guide rail according to a preferred embodiment of the present invention. Figures 1 to 3 as well as Figure 7 As shown, the bottom of the cage frame 2 is also provided with a plurality of wheel groups 24, and the loading area of ​​the vehicle 1 is provided with a grooved guide rail 11 arranged parallel to the translation assembly 3, so that the arrangement direction of the grooved guide rail 11 is consistent with the forward or backward movement direction of the cage frame 2, and when the cage frame 2 is translated along the central axis of the vehicle 1, the plurality of wheel groups 24 are all slidably arranged in the groove of the grooved guide rail 11, and the groove of the grooved guide rail 11 is arranged upward, that is, in the process of the cage frame 2 moving forward or backward, the wheel groups 24 can be guided by rolling in the groove of the grooved guide rail 11, which can reduce friction loss and improve the stability of the cage frame 2 during translation. It is worth pointing out that when the cage frame 2 is flipped, the plurality of wheel groups 24 will be disengaged from the groove of the grooved guide rail 11 to ensure that the cage frame 2 can be flipped smoothly.

[0033] Figure 8 FIG. 1 is a schematic diagram of the coordination of the fixed card slot and the auxiliary card slot in a preferred embodiment of the present invention. Figures 1 to 3 as well as Figure 8 As shown, a plurality of fixed slots 12 with slots facing the rear of the vehicle are also provided in the loading area of ​​the vehicle 1. At the same time, the bottom of the cage frame 2 is provided with auxiliary slots 25 with slots facing the front of the vehicle and matched with the plurality of fixed slots 12 one by one, so that when the cage frame 2 moves forward and the forward movement monitor 7 contacts the forward movement trigger plate 23, the auxiliary slots 25 and the fixed slots 12 are mutually engaged, thereby stably restricting the cage frame 2 in the loading area of ​​the vehicle 1 and ensuring stability during transportation. In addition, when the cage frame 2 moves backward toward the rear of the vehicle, the fixed slots 12 can be smoothly separated from the auxiliary slots 25, ensuring that the cage frame 2 can be flipped later. Preferably, the bottom slot wall of the auxiliary slot 25 and the top slot wall of the fixed slot 12 are arranged in an inclined surface, so that the bottom of the auxiliary slot 25 and the top of the fixed slot 12 can form a wedge-shaped structure, so that when the auxiliary slot 25 and the fixed slot 12 are engaged with each other, the bottom slot wall of the auxiliary slot 25 and the top slot wall of the fixed slot 12 abut against each other, and as the cage frame 2 moves forward toward the front of the vehicle under the action of the translation assembly 3, the greater the forward stroke, the tighter the fixed slot 12 and the auxiliary slot 25 are engaged, so that the cage frame 2 can be more stably installed on the cargo area of ​​the vehicle 1, avoiding the cage frame 2 from moving upward, reducing transportation vibration, and improving transportation stability. When the cage frame 2 moves backward toward the rear of the vehicle, the auxiliary slot 25 and the fixed slot 12 can be easily separated, and the structural design is more reasonable.

[0034] More specifically, an upward barb 331 is provided at one end of the support plate 33 away from the front of the vehicle, and the opening of the barb 331 is arranged toward the front of the vehicle, so that when the rearward movement monitor 8 contacts the rearward movement trigger plate, the pull rod 31 can move into the barb 331, and the upward movement of the pull rod 31 is limited by the barb 331, thereby preventing the pull rod 31 from accidentally moving upward when the cage frame 2 is turned over, causing the translation push rod 32 to bend, ensuring the performance of the translation push rod 32 and extending its service life. It is worth pointing out that when the translation push rod 32 drives the pull rod 31 to move toward the front of the vehicle, the pull rod 31 can be disengaged from the barb 331. Since the cage frame 2 is in a horizontal state at this time, it will no longer drive the pull rod 31 to move upward, and the structural design is more reasonable.

[0035] Fig. 9 This is a schematic diagram of the use of a flip wheel assembly according to a preferred embodiment of the present invention. Figures 1 to 3 as well as Fig. 9 As shown, the flip assembly 4 includes a flip wheel set 44 in addition to the above-mentioned flip plate 41 and other structures. Since the cage frame 2 in the flip process is connected to the flip plate 41 only through the flip front card slot 411 and the flip rear card slot 412 with notches and the front card plate 221 and the rear card plate 222, the cage frame 2 can still be disengaged from the notch direction of the flip front card slot 411 and the flip rear card slot 412, which poses a flip safety risk. At this time, the flip wheel set 44 can limit the cage frame 2 in the flip process from being disengaged along the notch direction of the flip front card slot 411 and the flip rear card slot 412, thereby improving flip safety. At this time, the flip wheel group 44 includes a wheel sleeve 441, a fixing plate 442 and a roller 443. The fixing plate 442 is installed on the cage frame 2. During installation, the roller 443 is rotatably installed on the fixing plate 442, so that the roller 443 can move forward or backward with the cage frame 2. At the same time, the wheel sleeve 441 is installed on the shaft support 42 to achieve stable installation of the wheel sleeve 441 on the vehicle 1, and the wheel sleeve 441 has a U-shaped bayonet arranged toward the front of the vehicle, so that when the cage frame 2 moves backward, the cage frame 2 can drive the roller 443 to smoothly enter the U-shaped bayonet of the wheel sleeve 441, and when the flip plate 41 rotates, the roller 443 in the U-shaped bayonet The wheel axle and the flip plate 41 are hinged to the rotating shaft on the rotating shaft support 42 and are arranged coaxially, so that the roller 443 can adapt to the flipping of the flip plate 41 in the wheel sleeve 441. Since the wheel sleeve 441 does not follow the flipping at this time, the direction of the U-shaped bayonet of the wheel sleeve 441 is still toward the front of the vehicle, so that the direction of the U-shaped bayonet is staggered with the slot direction of the front flip slot 411 and the rear flip slot 412. The side wall of the U-shaped bayonet limits the movement of the roller 443 along the slot direction of the front flip slot 411 and the rear flip slot 412, thereby limiting the cage frame 2 from escaping along the slot direction of the front flip slot 411 and the rear flip slot 412, thereby ensuring the flipping safety.

[0036] As a preferred embodiment, guide plates 13 are provided in the loading area of ​​the vehicle 1 and on both sides thereof, and guide slopes are provided on the upper part of the guide plates 13 and on the side close to the central axis of the vehicle 1, so that when the cage frame 2 enters the translation state from the flipping state, the two sides of the cage frame 2 can be guided by the guide slopes on the guide plates 13 respectively, so that the wheel group 24 at the bottom of the cage frame 2 can smoothly enter the groove of the grooved guide rail 11 on the vehicle 1, with higher matching accuracy and more reasonable structural design.

[0037] The express delivery vehicle loading and unloading structure and control method thereof provided in the present embodiment include a vehicle 1, a cage frame 2, a translation assembly 3, a flip assembly 4 and a plurality of trigger structures having a vertical monitor 5, a horizontal monitor 6, a forward monitor 7 and a backward monitor 8; the cage frame 2 is installed on the vehicle 1 and a translation assembly 3 and a flip assembly 4 independently installed on the vehicle 1 are arranged between the two, and the translation assembly 3 and the flip assembly 4 drive the cage frame 2 to move in a selective manner, thereby avoiding mutual interference between the translation and flipping processes of the cage frame 2, and also avoiding the stacking arrangement of the translation assembly 3 and the flip assembly 4, so that the structure is simpler. At the same time, different trigger structures are arranged at different positions of the vehicle 1, and the spatial state of the cage frame 2 is judged according to the trigger state of different trigger structures, so as to control the different modes of triggering the loading function key or the unloading function key, meet the one-key operation requirements for loading and unloading, and make the control more convenient, which is conducive to large-scale promotion and use.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
