[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] In the related art, operators usually use a trolley to carry components such as battery pack modules or battery plug-ins off-line, and then push them to other production lines to form a docking logistics line between multiple process production lines.

[0036] Since the battery pack module is easily damaged during transportation and loading and unloading, the operator in the related technology pushes the trolley for transportation, which often requires two people to work together. One person pushes the trolley to the designated loading and unloading position of the production line and ensures that the trolley is stationary, and the other person carries out the transportation and loading and unloading of the battery pack module or battery plug-in box. Manual handling has high cost, high labor intensity, and low work efficiency.

Figure 7 Schematic diagram of the structure of the unlocking block provided by the embodiment of the present invention. Figures 1 to 7 As shown, through practice, the applicant provides a battery pack module docking and conveying system, including a docking locking assembly 1 and a transport trolley 2.

[0038] Wherein, the docking locking assembly 1 includes a locking device 11 and a guide rail 12. The locking device 11 includes a strip connecting plate 111, a locking cylinder 112 and a magnetic block 113. The strip connecting plate 111 is used to be fixedly installed on the wall, the locking cylinder 112 is fixedly connected to one side plate of the strip connecting plate 111, the cylinder rod of the locking cylinder 112 is arranged in the vertical direction, and the magnetic block 113 is installed on one side plate of the strip connecting plate 111. The guide rail 12 is arranged in the horizontal direction, the guide rail 12 is perpendicular to the strip connecting plate 111, and one end of the guide rail 12 is opposite to the strip connecting plate 111 and is located below the locking cylinder 112. The guide rail 12 includes a base 121 and two guide plates 122 arranged in parallel and spaced apart in the horizontal direction, and the two guide plates 122 are parallel to the cylinder rod of the locking cylinder 112.

[0039] The top of the transport trolley 2 is provided with a bar track bracket 21 for placing the battery pack module, and a docking block 22 is provided on the vehicle body at one end of the bar track bracket 21. The docking block 22 has a positioning pin hole 221 that matches the cylinder rod of the locking cylinder 112, and the docking block 22 has a magnetic attraction matching surface 222 that matches the magnetic attraction block 113. The bottom of the vehicle body of the transport trolley 2 has a plurality of guide wheels 23 that match the guide rails 12, and a push handle 24 is provided on the vehicle body at the other end of the bar track bracket 21.

[0040] In an embodiment of the present invention, a docking locking assembly 1 is provided at the loading and unloading stations of different process production lines of lithium-ion batteries, wherein the strip connecting plate 111 is fixedly mounted on the wall by bolts or other fixing methods. The guide rail 12 is correspondingly arranged on the side of the strip connecting plate 111. When it is necessary to load and unload components such as battery pack modules or battery plug boxes, the operator can hold the push handle 24 to push the transport trolley 2 to move toward one of the docking locking assemblies 1. Before cooperating with the docking locking assembly 1, adjust the posture of the transport trolley 2, and align the multiple guide wheels 23 at the bottom of the transport trolley 2 with the guide rail 12 set on the ground in front of the strip connecting plate 111. Then continue to push the transport trolley 2, and fit the multiple guide wheels 23 into the guide rail 12 in turn, and use the guide rail 12 to guide the transport trolley 2, so that the docking block 22 on the transport trolley 2 is close to the strip connecting plate 111. Finally, the magnetic mating surface 222 of the docking block 22 will abut against the magnetic block 113 on the strip connecting plate 111, and the magnetic force of the magnetic block 113 will be used to adsorb the metal docking block 22 to complete the preliminary positioning of the transport trolley 2. While completing the preliminary positioning of the transport trolley 2 and the strip connecting plate 111, the positioning pin hole 221 on the docking block 22 can slide just below the locking cylinder 112 through the guidance of the guide rail 12. At this time, the operator can complete the docking and locking of the transport trolley 2 by controlling the cylinder rod of the locking cylinder 112 to extend and insert it into the positioning pin hole 221. Finally, the operator can release the grip of the push handle 24 and place the battery pack module m on the strip track bracket 21, or remove the battery pack module m from the strip track bracket 21 to achieve loading and unloading. By adopting the battery pack module docking and conveying system, after completing the docking positioning and locking of the transport trolley 2 and the docking locking assembly 1, the insertion structure between the cylinder rod of the locking cylinder 112 and the positioning pin hole 221, the magnetic structure between the magnetic block 113 and the magnetic matching surface 222 of the docking block 22, and the limiting structure between the guide rail 12 and the multiple guide wheels 23 can lock the transport trolley 2 on the wall where the loading station of the production line is located from multiple dimensions, ensuring that it remains stationary after the operator lets go, and there will be no relative shaking or sliding. It can achieve stable docking and locking of the trolley and the loading and unloading position of the production line, which is convenient for operators to independently carry and load and unload the battery pack module, reduce handling costs and labor intensity, and improve work efficiency.

[0041] Optionally, a positioning block 1111 is protrudingly provided on one side plate surface of the strip connecting plate 111, and a positioning groove 223 matching the positioning block 1111 is provided on the docking block 22. Exemplarily, in an embodiment of the present invention, the magnetic attraction mating surface 222 of the docking block 22 abuts against the magnetic attraction block 113 on the strip connecting plate 111, and while the magnetic attraction force of the magnetic attraction block 113 is used to adsorb the metal docking block 22, the positioning block 1111 on the strip connecting plate 111 will also be correspondingly inserted into the positioning groove 223 on the docking block 22. The mutually coordinated plug-in structure of the positioning block 1111 and the positioning groove 223 can further realize the limiting fixation of the transport trolley 2 in the horizontal direction perpendicular to the guide rail 12, thereby avoiding the relative shaking of the transport trolley 2 during the loading and unloading process of the battery pack module m, and further improving the coordination stability of the battery pack module docking and conveying system.

[0042] Optionally, the positioning block 1111 is V-shaped, and the positioning groove 223 is a V-shaped groove that matches the positioning block 1111. Exemplarily, in order to ensure the smoothness of the guide wheel 23 sliding in the guide rail 12, a certain assembly gap is inevitably required between the two. Therefore, there may be a certain angle deviation in the process of the docking block 22 on the transport trolley 2 approaching the strip connecting plate 111, resulting in the positioning block 1111 being unable to be correctly inserted into the positioning groove 223, and the positioning pin hole 221 being unable to accurately reach the bottom of the locking cylinder 112, requiring the staff to repeatedly adjust back and forth. In the embodiment of the present invention, by setting the positioning block 1111 and the positioning groove 223 to be a V-shaped structure, even if there is a certain angle deviation when cooperating with each other, the matching surfaces between the positioning block 1111 and the positioning groove 223 that are parallel to each other and inclined can also guide the transport trolley 2 in the length direction of the guide rail 12, and adjust the direction of the transport trolley 2, so that the positioning block 1111 can be smoothly inserted into the positioning groove 223 to complete the docking and locking, thereby further improving the work efficiency.

[0043] Optionally, the strip connecting plate 111 has two positioning blocks 1111, and the two positioning blocks 1111 are symmetrically arranged relative to the locking cylinder 112, and the docking block 22 has two positioning grooves 223 corresponding to the two positioning blocks 1111. By way of example, in an embodiment of the present invention, by symmetrically arranging two groups of positioning blocks 1111 and the matching structure of the positioning grooves 223 on both sides of the locking cylinder 112, its limiting and fixing ability is stronger. And after the positioning block 1111 is inserted into the positioning groove 223, it can avoid the vibration stress generated by the transport trolley 2 during the loading and unloading process from being concentrated on a single group of positioning blocks 1111 and the positioning groove 223, causing the problem of easy damage due to excessive stress, thereby further improving the overall service life of the battery pack module docking and conveying system.

[0044] Optionally, two cylindrical buffers 224 are provided on the docking block 22, and the cylindrical buffers 224 are arranged in the horizontal direction, and the two cylindrical buffers 224 are symmetrically arranged relative to the positioning pin hole 221. For example, in the embodiment of the present invention, by providing the cylindrical buffer 224 on the docking block 22, the transport trolley can be buffered and decelerated before the docking block 22 and the structure on the strip connecting plate 111 are in contact with each other, avoiding collision damage caused by excessive stress during mutual contact, and further improving the overall service life of the battery pack module docking and conveying system.

[0045] Optionally, the battery pack module docking and conveying system also includes a position sensor 3, which is installed on the locking cylinder 112 and electrically connected to the locking cylinder 112. The position sensor 3 is configured to control the extension and retraction of the cylinder rod of the locking cylinder 112 based on the distance between the docking block 22 and the strip connecting plate 111. For example, in an embodiment of the present invention, by setting the position sensor 3, the distance between the docking block 22 and the strip connecting plate 111 can be observed. After the magnetic mating surface 222 of the docking block 22 and the magnetic block 113 on the strip connecting plate 111 are in place, the position sensor 3 will automatically control the extension and retraction rod of the locking cylinder 112 to be inserted into the positioning pin hole 221, thereby completing the docking and locking of the transport trolley 2. There is no need for the staff to perform additional adjustment operations, which further improves work efficiency.

[0046] Optionally, the top of the transport trolley 2 has two bar track brackets 21, which are arranged in parallel and spaced apart, and a plurality of auxiliary pulleys 211 are provided on opposite sides of the two bar track brackets 21, and the plurality of auxiliary pulleys 211 are evenly spaced apart in the length direction of the bar track brackets 21. For example, in an embodiment of the present invention, the battery pack module m placed on the transport trolley 2 is supported as a whole on the two bar track brackets 21, and both sides of its bottom end surface are in contact with the auxiliary pulleys 211. The staff can push the battery pack module m to slide on the bar track bracket 21 through the auxiliary pulleys 211, which is convenient for loading and removing, and further improves work efficiency.

[0047] Optionally, the bar track bracket 21 has a non-return mechanism 4 for limiting the sliding travel of the battery pack module on the bar track bracket 21. Figures 5 to 7, illustratively, in the embodiment of the present invention, the check mechanism 4 includes a mounting seat 41, a check block 42, an unlocking block 43 and a plug-in pin 44, wherein the check block 42 and the unlocking block 43 are both in strip shape. The mounting seat 41 has a first groove 411 and a second groove 412 that are vertically connected, the check block 42 is arranged in the first groove 411, one end of the check block 42 is rotatably connected to the first groove 411 through a rotating shaft 421, the other end of the check block 42 has a through hole 422, the through hole 422 is parallel to the rotating shaft 421, a spring 45 is arranged between the other end of the check block 42 and the bottom of the first groove 411, one end of the spring is connected to the bottom of the first groove 411, and the other end of the spring abuts against the bottom of the other end of the check block 42. The unlocking block 43 is arranged in the second groove 412, one end of the unlocking block 43 is plugged into the through hole 422 through a protruding plug 431, and the other end of the unlocking block 43 is detachably connected to the mounting seat 41 through the plug-in pin 44. After the battery pack module m is mounted on the strip track bracket 21, the operator can remove the plug pin 44 from the mounting seat 41, adjust the position of the unlocking block 43 in the second groove 412, and release the lock on the other end of the check block 42 by disengaging the plug pin 431 from the through hole 422. At this time, the check block 42 will pop up under the elastic force of the spring 45 and rotate around the rotating shaft 421 to stand up. At this time, the check block 42 can limit the protrusion m1 on the side of the battery pack module m to prevent the battery pack module m from sliding too much on the strip track bracket 21 due to vibration during transportation, reduce the risk of falling from the transport trolley 2, and further improve the working safety of the battery pack module docking and conveying system.

[0048] Optionally, a buffer rod 212 is provided on the vehicle body at the other end of the bar track bracket 21, and the buffer rod 212 is arranged parallel to the bar track bracket 21 and toward the non-return mechanism 4. For example, in the embodiment of the present invention, by providing the buffer rod 212 facing the non-return mechanism 4 at one end of the bar track bracket 21 provided with the push handle 24, when the battery pack module m is being loaded and unloaded by sliding, or the non-return mechanism 4 is used to limit the battery pack module m to prevent it from falling during transportation, when the battery pack module is about to collide with the baffle at the end of the bar track bracket 21 due to factors such as shaking or inertia, the buffer rod 212 will first contact the battery pack module m, play a role of buffering and limiting, avoid damage to the battery pack module m caused by collision, and further improve the working safety of the battery pack module docking and conveying system.

Align the multiple guide wheels 23 located at the bottom of the transport trolley 2 with the guide rail 12, fit the multiple guide wheels 23 into the guide rail 12, and use the guide rail 12 to guide the transport trolley 2 so that the magnetic mating surface 222 of the docking block 22 abuts against the magnetic block 113 on the strip connecting plate 111.

[0053] Specifically, before engaging with the docking locking assembly 1, adjust the posture of the transport trolley 2, and align the multiple guide wheels 23 at the bottom of the transport trolley 2 with the guide rails 12 set on the ground in front of the strip connecting plate 111. Then continue to push the transport trolley 2, and engage the multiple guide wheels 23 in turn into the guide rails 12, and use the guide rails 12 to guide the transport trolley 2, so that the docking block 22 on the transport trolley 2 is close to the strip connecting plate 111. Finally, the magnetic attraction mating surface 222 of the docking block 22 will abut against the magnetic attraction block 113 on the strip connecting plate 111, and the magnetic attraction force of the magnetic attraction block 113 will be used to adsorb the metal docking block 22, completing the preliminary positioning of the transport trolley 2.

[0054] S3, controlling the cylinder rod of the locking cylinder 112 to extend and insert into the positioning pin hole 221, thereby completing the docking and locking of the transport trolley 2.

[0055] Specifically, when the transport trolley 2 and the strip connecting plate 111 are initially positioned, the positioning pin hole 221 on the docking block 22 can slide just below the locking cylinder 112 under the guidance of the guide rail 12. At this time, the operator can control the cylinder rod of the locking cylinder 112 to extend and insert it into the positioning pin hole 221, thereby completing the docking and locking of the transport trolley 2.

[0056] S4, placing the battery pack module on the bar track bracket 21, or removing the battery pack module from the bar track bracket 21.
