The adjusting member is arranged with a relative interval to the end plate portion, which can reduce the interference of the end plate portion on the floating process of the adjusting member, and improve the stability and flexibility of the adjusting member during the floating process.

[0010] In some embodiments, the docking device includes at least one second elastic member, the mounting shell includes an end plate portion, the adjustment member is spaced apart from the end plate portion, and the second elastic member is elastically supported between the adjustment member and the end plate portion. Thus, the second elastic member is elastically supported between the adjustment member and the end plate portion, and the second elastic member and the end plate portion cooperate to provide a floating space for the adjustment member, thereby improving the stability of the connection between the adjustment member and the end plate portion, and the second elastic member can also buffer and limit the floating movement of the adjustment member, and quickly reset the adjustment member after the docking device and the external device are out of docking.

[0011] In some embodiments, the docking device includes a first sleeve and a second sleeve, the first sleeve is arranged on the side of the adjustment member facing the end plate, the second sleeve is arranged on the side of the end plate facing the adjustment member, the first sleeve and the second sleeve are arranged opposite to each other and spaced apart, and a second elastic member is respectively sleeved on the outside of the first sleeve and the corresponding second sleeve.

[0015] In some embodiments, the docking device further comprises a third elastic member, which is sleeved on the outside of the guide rod and is located between the adjustment member and the docking guide member. Thus, by sleeved on the outside of the guide rod and between the adjustment member and the docking guide member, the movement path of the guide rod in the guide hole can be limited by the third elastic member, thereby reducing the risk of poor guiding effect of the docking guide member due to excessive movement of the guide rod.

[0016] In some embodiments, a guiding bevel is provided on the outer circumference of the docking guide, and the circumferential dimension of the guiding bevel gradually decreases in the direction away from the adjustment member.

[0041] At present, judging from the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric vehicles, and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding. For example, it is an inevitable trend to use intelligent robot inspections instead of manual patrols in factories, substations, tunnels, industrial parks and other places. Robots are mostly powered by battery packs. When the robot is low on power, it will return to the robot's charging station for automatic docking to complete charging.

[0042] In order to solve the technical problems existing in the related technology, this application provides a docking system, see Figure 1 , Figure 1 is a schematic diagram of the structure of a docking system according to one or more embodiments.

[0043] The docking system 1 includes an external device 20 and a docking device 10. Both the external device 20 and the docking device 10 may include, but are not limited to, an AGV (Automated Guided Vehicle), a sweeping robot, a charging pile, and other equipment. For example, the AGV includes an electromagnetic, optical, or visual automatic guidance device, so that the AGV can travel along a predetermined route or a route planned by itself, and thus can be used as a transport vehicle with a carrying function.

[0044] Generally speaking, robots can rely on batteries for power. After running for a period of time, the battery power gradually decreases, so the robot needs to drive to a predetermined charging location and then charge it through a charging device. Among them, the battery mentioned in this field can be a secondary battery (Secondary Battery) or a secondary battery, a storage battery. The manufacturing materials and processes of rechargeable batteries are different from those of primary batteries. Its advantage is that it can be recycled many times after charging, and the output current load capacity of rechargeable batteries is higher than that of most disposable batteries. Currently, the common types of rechargeable batteries are: lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Lithium-ion batteries have the advantages of light weight, large capacity (the capacity is 1.5 to 2 times that of nickel-metal hydride batteries of the same weight), no memory effect, and have a very low self-discharge rate. Therefore, even though the price is relatively high, it is still widely used.

[0045] One of the external device 20 and the docking device 10 can be a charging device, and the other can be an electric device. The charging device can charge the electric device. The charging method can include manual charging and automatic charging. Manual charging requires manual labor, so additional labor is required to participate in the work, which increases costs and wastes time. In the automatic charging method, the charging connector of the electric device needs to be accurately docked with the connector of the charging device before the charging operation can be performed.

[0046] However, in actual operation, due to the limited alignment space of the connector and the difficulty in accurately controlling the position of the connector, the connector of the docking device 10 is often difficult to accurately dock with the connector of the external device 20, making it difficult to smoothly perform the docking operation.

[0047] In order to solve the technical problems existing in the related art, the present application provides a docking device, see Figure 2 , Figure 2 is a first structural schematic diagram of a docking device according to one or more embodiments.

[0048] The docking device 10 includes a mounting shell 100, an adjustment member 200 and a docking member 300, wherein the adjustment member 200 is arranged opposite to the mounting shell 100; one end of the docking member 300 is connected to the adjustment member 200, and the other end of the docking member 300 extends in a direction away from the adjustment member 200, and the other end of the docking member 300 is used for docking with the external device 20.

[0049] The mounting shell 100 may be in any shape, for example, the mounting shell 100 may be in a circular plate shape, a square plate shape, a hollow shell shape, etc. The adjustment member 200 may be arranged opposite to the mounting shell 100 and spaced apart. For example, when the mounting shell 100 is in a hollow shell shape, the adjustment member 200 may be arranged opposite to the bottom wall of the mounting shell 100 and spaced apart. The adjustment member 200 may be in a plate shape or any other shape. The docking member 300 may be located on the side of the adjustment member 200 away from the mounting shell 100 and extend in a direction away from the adjustment member 200; or one end of the docking member 300 may be connected to the side of the adjustment member 200 facing the mounting shell 100, and the other end may pass through the mounting shell 100 and gradually extend in a direction away from the adjustment member 200. The external device 20 may be an electrical device or a charging device that needs to be connected to the docking device 10. For example, the external device 20 may include but is not limited to a self-propelled robot, a charging pile, an unmanned guided vehicle, etc. When the external device 20 needs to be docked with the docking device 10 , the external device 20 can be docked with the docking device 10 via the other end of the docking member 300 .

[0050] The adjusting member 200 is elastically connected to the mounting shell 100 to allow the adjusting member 200 to float relative to the mounting shell 100, thereby adjusting the position of the other end of the docking member 300. The adjusting member 200 itself can be spaced apart from the mounting shell 100, and can be elastically connected to the mounting shell 100 through elastic members such as springs and shrapnel, or the adjusting member 200 itself is elastic and is directly elastically connected to the mounting shell 100, so that when the adjusting member 200 is subjected to an external force, the adjusting member 200 can float relative to the mounting shell 100 under the action of the external force. For example, the adjusting member 200 can move in multiple directions such as up, down, left, and right relative to the mounting shell 100, and can rotate relative to the mounting shell 100 around multiple rotation axes. One end of the docking member 300 is connected to the adjusting member 200, and the other end is used to dock with the external device 20. When the external device 20 needs to dock with the other end of the docking member 300, the docking device 10 and the external device 20 move relative to each other, and the external device 20 contacts the other end of the docking member 300. When there is an error in docking between the external device 20 and the other end of the docking member 300, the external device 20 applies an external force to the other end of the docking member 300 during the docking process, and the external force is transmitted to the adjusting member 200, so that the adjusting member 200 floats under the action of the external force. Since one end of the docking member 300 is connected to the adjusting member 200, when the adjusting member 200 floats, the adjusting member 200 drives the other end of the docking member 300 to move relative to the external device 20, so that the other end of the docking member 300 completes the docking with the external device 20.

[0051] Through the above-mentioned implementation mode, the docking member 300 is connected to the adjustment member 200, and the adjustment member 200 is elastically connected to the mounting shell 100, so that the adjustment member 200 can float compared to the mounting shell 100. When the external device 20 needs to dock with the docking member 300, it will first contact the docking member 300 to apply an external force to the docking member 300. The external force will be transmitted to the adjustment member 200 via the docking member 300, causing the adjustment member 200 to float, thereby driving the docking member 300 to adjust the position of the other end of the docking member 300 from multiple directions, thereby absorbing the error generated in the automatic docking process, completing the precise docking of the docking member 300 and the external device 20, and improving the docking efficiency of the docking device 10 and the external device 20.

[0052] In some embodiments, the docking device 10 includes a plurality of first elastic members 400, and the plurality of first elastic members 400 are arranged at intervals along the circumference of the adjustment member 200, and each first elastic member 400 is respectively connected to the adjustment member 200 and the mounting shell 100. The first elastic member 400 may be a component having elasticity, such as a spring or a shrapnel, so that the adjustment member 200 can be elastically connected to the mounting shell 100 through the first elastic member 400. The elastic coefficients of the plurality of first elastic members 400 may be the same or different, and the plurality of first elastic members 400 may be arranged at equal intervals along the circumference of the adjustment member 200. For example, there may be two first elastic members 400, and the two first elastic members 400 are arranged oppositely and at intervals, or there may be three first elastic members 400, and the three first elastic members 400 are arranged at equal intervals along the circumference of the adjustment member 200. The plurality of first elastic members 400 may also be arranged at unequal intervals along the circumference of the adjustment member 200, such as Figure 2 As shown, the docking device 10 includes four first elastic members 400, the adjustment member 200 is in the shape of a rectangular parallelepiped plate, and one first elastic member 400 is connected to one corner of the adjustment member 200, so that the adjustment member 200 and the mounting shell 100 are elastically connected. Thus, the plurality of first elastic members 400 are arranged at intervals along the circumference of the adjustment member 200, and the adjustment member 200 is elastically connected to the mounting shell 100 through the plurality of first elastic members 400, which can improve the stability of the connection between the adjustment member 200 and the mounting shell 100, as well as the stability of the adjustment member 200 during the floating process, further facilitate the completion of the precise docking of the docking member 300 and the external device 20, and improve the docking efficiency of the docking device 10 and the external device 20.

[0053] Combination Figure 3 , Figure 3 yes Figure 2 An enlarged schematic diagram of the structure in the dotted frame A in the docking device shown.

[0054] The first elastic member 400 includes an elastic body 410 and two fixing parts 420, the two fixing parts 420 are respectively connected to the two ends of the elastic body 410, and the elastic body 410 is respectively connected to the adjustment member 200 and the mounting shell 100 through the two fixing parts 420. The elastic body 410 can be a spring-type structure, and the elastic body 410 can be elastically deformed under the action of external force. The two fixing parts 420 can be integrally formed with the elastic body 410, and the adjustment member 200 and the mounting shell 100 can be provided with a structure that cooperates with the two fixing parts 420. Thus, the adjustment member 200 is connected to the mounting shell 100 through the two fixing parts 420 and the elastic body 410, which can further improve the stability of the connection between the adjustment member 200 and the mounting shell 100, as well as the stability and flexibility of the adjustment member 200 during the floating process.

[0055] Further, the fixing portion 420 is bent, the adjusting member 200 is provided with a first fixing hole 210, the mounting shell 100 is provided with a second fixing hole 131, and the fixing portions 420 at both ends of the elastic body 410 are hooked in the first fixing hole 210 and the second fixing hole 131 respectively. The fixing portion 420 can be bent to form a hook shape, and the first fixing hole 210 and the second fixing hole 131 can both be through-hole structures, such as the first fixing hole 210 can penetrate the opposite surfaces of the adjusting member 200. The spacing between the first fixing hole 210 and the second fixing hole 131 can be set to: when the fixing portion 420 is hooked in the first fixing hole 210 and the second fixing hole 131, the elastic body 410 is in a stretched state. Thus, the fixing portion 420 is bent, and the elastic body 410 is hooked in the first fixing hole 210 and the second fixing hole 131 respectively through the two fixing portions 420, which can improve the stability of the connection between the adjusting member 200 and the mounting shell 100, and facilitate the disassembly and maintenance of the first elastic member 400.

The flange portion 130 is provided with a second fixing hole 131. When the adjusting member 200 is connected to the mounting shell 100 through a plurality of first elastic members 400, the adjusting member 200 may be arranged opposite to and spaced from the end plate portion 110, so that the adjusting member 200 has sufficient floating space when subjected to external force. Thus, the second fixing hole 131 is located at the flange portion 130, which makes it easier to form the second fixing hole 131, reduces the processing difficulty, and can also facilitate the elastic body 410 to be hooked in the second fixing hole 131 through the fixing portion 420. The adjusting member 200 is arranged opposite to and spaced from the end plate portion 110, which can reduce the interference of the end plate portion 110 on the floating process of the adjusting member 200, and improve the stability and flexibility of the adjusting member 200 during the floating process.

Alternatively, the number of the second elastic members 500 may be multiple, the elastic coefficients of the multiple second elastic members 500 may be the same or different, and the multiple second elastic members 500 may be spaced apart. For example, there may be two second elastic members 500, and the two second elastic members 500 may be equally spaced relative to the two side edges of the adjustment member 200, such as Figure 2As shown, the number of the second elastic members 500 is four, and the four second elastic members 500 can be divided into two groups, each group including two second elastic members 500, and the spacing between the left side group of second elastic members 500 and the left edge of the adjusting member 200 is the same or substantially the same as the spacing between the right side group of second elastic members 500 and the right edge of the adjusting member 200. In the two second elastic members 500 in the same group, the spacing between the upper side second elastic member 500 and the upper edge of the adjusting member 200 is the same or substantially the same as the spacing between the lower side second elastic member 500 and the lower edge of the adjusting member 200. Thus, the second elastic member 500 is elastically supported between the adjusting member 200 and the end plate portion 110, and can provide floating space for the adjusting member 200 through the cooperation of the second elastic member 500 and the end plate portion 110, thereby improving the stability of the connection between the adjusting member 200 and the end plate portion 110, and can also buffer and limit the floating movement of the adjusting member 200 through the second elastic member 500, and can quickly reset the adjusting member 200 after the docking device 10 and the external device 20 are out of the docking state.

[0058] Combination Figure 4 and Figure 5 , Figure 4 yes Figure 2 The schematic diagram of the structure of the docking device shown in FIG. 1 is a schematic diagram of the structure of the docking device without the adjusting parts. Figure 5 yes Figure 2 The schematic diagram of the structure of the docking device shown is shown with the mounting shell removed.

[0059] The docking device 10 includes a first sleeve 610 and a second sleeve 620. The first sleeve 610 is arranged on the side of the adjustment member 200 facing the end plate 110, and the second sleeve 620 is arranged on the side of the end plate 110 facing the adjustment member 200. The first sleeve 610 and the second sleeve 620 are arranged opposite to each other and spaced apart.

The first sleeve 610 can be columnar, and the end surface of the first sleeve 610 facing the adjustment member 200 can be provided with a concave threaded hole, and the corresponding position of the adjustment member 200 can also be provided with a threaded hole. The threaded hole on the adjustment member 200 can be a through hole, and a bolt can be inserted into the threaded holes of the adjustment member 200 and the first sleeve 610 from the side of the adjustment member 200 away from the first sleeve 610, so as to fix the adjustment member 200 and the first sleeve 610. The second sleeve 620 may be columnar, and the end surface of the second sleeve 620 facing the end plate 110 may be provided with a concave threaded hole, and the corresponding position of the mounting shell 100 may also be provided with a threaded hole, and the threaded hole on the mounting shell 100 may be a through hole, and a bolt may be inserted from the side of the mounting shell 100 away from the second sleeve 620 into the threaded hole of the mounting shell 100 and the second sleeve 620, so as to fix the mounting shell 100 and the second sleeve 620. The second elastic member 500 may be a coil spring, so that the second elastic member 500 can be respectively sleeved on the outside of the first sleeve 610 and the corresponding second sleeve 620. Therefore, by sleeved on the outside of the first sleeve 610 and the second sleeve 620, the stability of the elastic support of the second elastic member 500 between the adjustment member 200 and the mounting shell 100 can be improved, and the fixing method is simple, which is convenient for installation and disassembly.

[0060] Further, the first sleeve 610 includes a first base 611 and a first sleeve portion 612. The radial dimension of the first base 611 is greater than the radial dimension of the first sleeve portion 612. The first base 611 is connected to the adjustment member 200. The first sleeve portion 612 is arranged on the side of the first base 611 away from the adjustment member 200. The second elastic member 500 is sleeved on the first sleeve portion 612. The first base 611 and the first sleeve portion 612 can both be columnar. The first sleeve portion 612 can be located at a relatively central position of the first base 611. The first sleeve portion 612 can be spaced apart from the end plate portion 110. The first base 611 is connected to the adjustment member 200. The second elastic member 500 is sleeved on the first sleeve portion 612, and the second elastic member 500 can be elastically supported between the first base 611 and the end plate portion 110.

[0061] The second sleeve connecting member 620 includes a second base 621 and a second sleeve connecting portion 622. The radial dimension of the second base 621 is greater than the radial dimension of the second sleeve connecting portion 622. The second base 621 is connected to the end plate portion 110.

The second sleeve connecting portion 622 may be located at a relatively central position of the second base 621. The second sleeve connecting portion 622 may be spaced apart from the adjusting member 200. The second base 621 is connected to the end plate portion 110. The second elastic member 500 is sleeved on the second sleeve connecting portion 622, and the second elastic member 500 may be elastically supported between the second base 621 and the adjusting member 200.

[0062] When the first sleeve 610 includes a first base 611 and a first sleeve portion 612, and the second sleeve 620 includes a second base 621 and a second sleeve portion 622, the first sleeve portion 612 and the second sleeve portion 622 can be arranged opposite to each other and spaced apart. Thus, by connecting the first base 611 with a larger size to the adjusting member 200, the stability of the connection between the first base 611 and the adjusting member 200 can be improved, and the first sleeve portion 612 has a smaller size, which makes it easier for the second elastic member 500 to be mounted, thereby reducing the difficulty of installation and improving production efficiency. And / or, by connecting the second base 621 with a larger size to the end plate 110, the stability of the connection between the second base 621 and the end plate 110 can be improved, and the second sleeve portion 622 has a smaller size, which makes it easier for the second elastic member 500 to be mounted, thereby reducing the difficulty of installation and improving production efficiency.

[0063] In some embodiments, the docking device 10 further includes a docking guide 710 and a guide rod 720. The docking guide 710 is sleeved on the outer side of the other end of the docking member 300. The guide rod 720 is respectively connected to the docking guide 710 and the adjustment member 200. The docking guide 710 is used to guide the other end of the docking member 300 to dock with the external device 20. The docking guide 710 may be hollow, and the radial dimension of the internal through hole of the docking guide 710 may be slightly larger than the radial dimension of the other end of the docking member 300, so that when the docking guide 710 is sleeved on the outer side of the other end of the docking member 300, the inner side wall of the internal through hole of the docking guide 710 is spaced from the outer side wall of the other end of the docking guide 710, so that the docking guide 710 can move relative to the docking member 300 under the action of external force. The docking guide 710 is connected to the adjustment member 200 through the guide rod 720. When the adjustment member 200 floats under the action of external force, the position of the docking guide 710 can be changed through the guide rod 720. For example, when the external device 20 needs to dock with the other end of the docking member 300, the docking device 10 and the external device 20 move relative to each other, and if the external device 20 and the other end of the docking member 300 are not completely aligned, the external device 20 can first contact the docking guide 710 and apply an external force to the docking guide 710, and the external force can be transmitted to the adjustment member 200 through the guide rod 720, so that the adjustment member 200 floats under the action of the external force. When the adjustment member 200 floats, the adjustment member 200 will drive the docking guide 710 to move relative to the external device 20, so as to guide the external device 20 to complete the docking with the other end of the docking member 300. Therefore, the docking member 300 guide is sleeved on the other end of the docking member 300, and the guide rod 720 is respectively connected to the adjustment member 200 and the docking guide 710, and the docking guide 710 and the guide rod 720 can cooperate to improve the accuracy and efficiency of docking between the docking member 300 and the external device 20.

[0064] Further, the adjusting member 200 is provided with a guide hole 740, and the guide rod 720 is inserted into the guide hole 740, and the guide rod 720 can move in the guide hole 740. The guide hole 740 is a through hole, and the guide hole 740 can penetrate the opposite surfaces of the adjusting member 200. One end of the guide rod 720 is fixedly connected to the docking guide member 710, and the other end is inserted into the guide hole 740. When the docking guide member 710 is subjected to an external force, the external force can be transmitted to the guide rod 720 through the docking guide member 710, and the guide rod 720 moves in the guide hole 740 under the action of the external force, so that the docking guide member 710 moves relative to the external device 20, so as to guide the external device 20 to complete docking with the other end of the docking member 300. The number of the guide rods 720 and the guide holes 740 can be multiple, for example, the number of the guide rods 720 and the guide holes 740 is two, and the two guide rods 720 are arranged at intervals on both sides of the docking member 300, and one end of the two guide rods 720 is respectively connected to the docking guide member 710, and the other end is respectively inserted into a guide hole 740. Therefore, the guide rod 720 moves in the guide hole 740, and the guide rod 720 and the guide hole 740 cooperate to guide the docking guide member 710 to move relative to the docking member 300, which makes it easier to guide the docking device 10 to dock with the docking member 300, and further improves the accuracy and efficiency of docking between the docking member 300 and the external device 20.

[0065] Further, the docking device 10 further includes a third elastic member 730, which is sleeved on the outer side of the guide rod 720, and the third elastic member 730 is located between the adjustment member 200 and the docking guide member 710. The third elastic member 730 may be a spring structure, so that the third elastic member 730 is sleeved on the outer side of the guide rod 720. In a natural state, one end of the third elastic member 730 is fixedly connected to the docking guide member 710, and the other end of the third elastic member 730 may be spaced apart from the adjustment member 200. When the docking guide member 710 is subjected to an external force, the external force may be transmitted to the guide rod 720 via the docking guide member 710, and the guide rod 720 moves in the guide hole 740 under the action of the external force. When the path of movement of the guide rod 720 is long, one end of the third elastic member 730 away from the docking guide member 710 abuts against the adjustment member 200, so that the moving path of the guide rod 720 may be limited by the third elastic member 730. Therefore, by sleeved the third elastic member 730 on the outside of the guide rod 720 and positioned between the adjustment member 200 and the docking guide member 710, the movement path of the guide rod 720 in the guide hole 740 can be limited by the third elastic member 730, thereby reducing the risk of the guiding effect of the docking guide member 710 being deteriorated due to excessive movement of the guide rod 720.

[0066] In some embodiments, a guide slope 711 is provided on the outer circumference of the docking guide 710, and the circumferential dimension of the guide slope 711 gradually decreases in the direction away from the adjustment member 200. When the external device 20 needs to dock with the other end of the docking member 300, the external device 20 can first contact the docking guide 710 and apply an external force to the docking guide 710. Since the circumferential dimension of the guide slope 711 gradually decreases in the direction away from the adjustment member 200, when the docking guide 710 receives the external force, the guide slope 711 guides the external device 20 and the docking guide 710 to move relative to each other, thereby guiding the external device 20 to align with the other end of the docking member 300. Therefore, by providing the guide slope 711 on the outer circumference of the docking guide 710, the docking efficiency of the docking guide 710 guiding the docking member 300 to dock with the external device 20 can be further improved.

[0067] In some embodiments, the docking guide 710 is provided with a plurality of guide grooves 712, and the plurality of guide grooves 712 are arranged at intervals along the circumference of the docking member 300. The guide groove 712 can be provided at the end of the docking guide 710 away from the adjustment member 200. For example, the end surface of one side of the docking guide 710 away from the adjustment member 200 is recessed inward to form the guide groove 712. The external device 20 can be provided with a guide protrusion. When the external device 20 needs to dock with the other end of the docking member 300, the guide protrusion of the external device 20 can be inserted into the guide groove 712 of the docking guide 710 to position the external device 20 through the docking guide 710. The number of the guide grooves 712 can be multiple, such as two guide grooves 712, and the two guide grooves 712 can be located on both sides of the other end of the docking member 300. In some other embodiments, the docking guide 710 may be provided with a guide protrusion, and the external device 20 may be provided with a groove corresponding to the guide protrusion, so as to position the external device 20 through the docking guide 710. Thus, by providing the guide groove 712 on the docking guide 710 and guiding the docking through the guide groove 712, the docking efficiency of the docking guide 710 guiding the docking member 300 and the external device 20 to dock can be further improved.

[0068] In some embodiments, the docking member 300 includes a fixed support 320 and a docking portion 310, and the two ends of the fixed support 320 are respectively connected to the docking portion 310 and the adjustment member 200, and the docking portion 310 is used to dock with the external device 20. The fixed support 320 is respectively connected to the docking portion 310 and the adjustment member 200, and the docking portion 310 can be fixed at a specific position by the fixed support 320, so as to facilitate the molding of the docking member 300. The docking portion 310 can be a charging plug or a charging socket, etc., and a hollow wire hole can be provided in the middle of the fixed support 320. The charging cable can be inserted into the hollow wire hole of the fixed support 320 and connected to the docking portion 310, so that the charging operation can be performed after the docking is completed. Therefore, the docking portion 310 is connected to the adjustment member 200 through the fixed support 320, which can reduce the molding difficulty of the docking member 300 and improve the production efficiency.

[0069] In some embodiments, the docking member 300 is inserted through the mounting shell 100, and the other end of the docking member 300 extends to the side of the mounting shell 100 away from the adjustment member 200. A avoidance hole may be provided on the side of the mounting shell 100 away from the adjustment member 200, one end of the docking member 300 is connected to the adjustment member 200, and the other end of the docking member 300 passes through the mounting shell 100 through the avoidance hole on the mounting shell 100 and extends to the outside of the mounting shell 100. The size of the avoidance hole can be set so that when the adjustment member 200 floats, the mounting shell 100 and the docking member 300 form an avoidance, so as to minimize the risk of interference between the mounting shell 100 and the docking member 300 due to the avoidance hole being too small, thereby affecting the adjustment of the position of the other end of the docking member 300. Or the size of the avoidance hole can be set so that when the adjustment member 200 floats, the mounting shell 100 limits the floating degree of the docking member 300, so as to minimize the risk of difficulty in achieving accurate docking due to excessive floating of the adjustment member 200.

[0070] Combination Figure 6 , Figure 6 is a second structural schematic diagram of a docking device according to one or more embodiments.

[0071] The docking device 10 further includes a docking guide 710 and a protective cover 820. The docking guide 710 is sleeved on the outer side of the other end of the docking member 300. The protective cover 820 is connected to the docking guide 710 and the mounting shell 100, respectively, and is sleeved on the outer side of a portion of the docking member 300 located between the docking guide 710 and the mounting shell 100. The protective cover 820 may be in a sleeve shape. When the docking member 300 is inserted into the mounting shell 100 and the other end of the docking member 300 extends to the side of the mounting shell 100 away from the adjustment member 200, the protective cover 820 may be sleeved on the outer side of a portion of the docking member 300 located between the docking guide 710 and the mounting shell 100, so as to protect the docking member 300 from dust and other effects through the protective cover 820. The protective cover 820 may be detachably connected or fixedly connected to both the docking guide 710 and the mounting shell 100. The protective cover 820 may be a soft body, such as the protective cover 820 may be made of rubber material, so that the protective cover 820 can move together with the docking guide 710 to reduce the risk of the protective cover 820 causing docking interference.

[0072] In some embodiments, the docking device 10 further includes a protective shell 810, the protective shell 810 is formed with a receiving cavity, the adjustment member 200 is located in the receiving cavity, and the mounting shell 100 is installed at the open end of the receiving cavity. The protective shell 810 may be a hollow structure to form a receiving cavity inside the protective shell 810, the adjustment member 200 is located in the receiving cavity, and the mounting shell 100 may be fixed to the open end of the receiving cavity to seal the receiving cavity through the mounting shell 100. For example, the mounting shell 100 may be embedded in the receiving cavity so that the outer peripheral wall of the mounting shell 100 abuts against the inner peripheral wall of the receiving cavity, and then the mounting shell 100 and the protective shell 810 may be locked and fixed by a locking bolt. Thus, the adjustment member 200 is located in the receiving cavity, and the mounting shell 100 is installed at the open end of the receiving cavity, and the protective shell 810 can protect the adjustment member 200, and the mounting shell 100 can also be installed and fixed by the protective shell 810, simplifying the installation process.
