[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0052] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0053] In related technologies, more and more scenarios use robots such as delivery robots and service robots to replace manual labor. The premise for robots to realize various functions is that they need built-in battery modules to continuously power each functional module or actuator.

[0054] In order to meet the daily use of the robot, the battery capacity of the built-in battery module of the robot is usually higher than 10Ah. In this case, the robot body and the battery module must be transported separately during transportation. At this time, the battery module needs to be detachable relative to the battery compartment in the robot body. In this way, the battery module can be separately disassembled and packaged for transportation during transportation, and the battery module can be quickly installed in the battery compartment of the robot when it arrives for installation. However, the locking between the built-in battery module and the battery compartment of the current robot is not secure enough, especially when the robot encounters frequent bumps during walking, there is a risk of the battery loosening, affecting the normal use of the robot.

[0055] In view of this, refer to Figure 1 and Figure 2 The embodiment of the present application provides a locking structure 100, which is used to lock or unlock the battery compartment 200 and the battery module 300 in the battery compartment module 10. Specifically, two locking structures 100 with the same structure are respectively arranged on the opposite sides of the battery compartment 200 to respectively lock the left and right sides of the battery module 300 to improve the stability of the battery module 300 installed in the battery compartment 200. Among them, in the locking structure 100, a locking member 110, a connecting column 120, an elastic member 130 and a blocking member 140 are arranged, and the locking member 110 is rotatably connected to the battery compartment 200 through the connecting column 120, and the locking member 110 can rotate back and forth between a locking position and an unlocking position under the action of an external force; and, an elastic member 130 is arranged around the outer periphery of the connecting column 120 between the blocking member 140 and the locking member 110, and the two ends of the elastic member 130 are respectively abutted against the blocking member 140 and the battery compartment 200, so that the elastic member 130 can provide a pre-tightening force along the axial direction of the connecting column 120.

[0056] In this way, when the locking member 110 is in the locking position and the external force on the locking member 110 is removed, the elastic member 130 pushes against the blocking member 140 and the battery compartment 200 respectively, so that in the axial direction of the connecting column 120, the locking member 110 is pressed against the surface of the battery module 300, thereby locking the battery compartment 200 and the battery module 300, and effectively preventing the battery module 300 from loosening in the battery compartment 200.

[0057] The following is combined with Figures 1 to 7 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0058] like Figure 1 , Figure 2 and Figure 5As shown, the locking structure 100 provided in the embodiment of the present application includes a locking member 110, a connecting column 120, an elastic member 130 and a blocking member 140, the connecting column 120 is used to be rotatably connected to the battery compartment 200; the locking member 110 and the blocking member 140 are respectively connected to the axial ends of the connecting column 120, and are respectively used to be arranged on both sides of the battery compartment 200; the elastic member 130 is arranged around the connecting column 120, and one end of the elastic member 130 is abutted against the blocking member 140, and the other end of the elastic member 130 is used to abut against the battery compartment 200; the locking member 110 is used to move along the axial direction of the connecting column 120 under the action of an external force, and drive the blocking member 140 to move to compress the elastic member 130, and the locking member 110 is also used to rotate around the connecting column 120 between an unlocking position and a locking position under the action of an external force; when the locking member 110 is in the locked position, the locking member 110 is used to press against the surface of the battery module 300 under the action of the elastic member 130.

[0059] In this embodiment, the locking structure 100 includes a locking member 110, a connecting column 120, an elastic member 130 and a blocking member 140. The locking member 110 and the blocking member 140 are respectively connected to the two axial ends of the connecting column 120. The elastic member 130 is arranged around the connecting column 120, and one end of the elastic member 130 is abutted against the blocking member 140, and the other end of the elastic member 130 is used to abut against the battery compartment 200. The structure is simple and can save manufacturing processes during manufacturing, thereby reducing manufacturing costs.

[0060] Moreover, the locking member 110 and the blocking member 140 are respectively connected to the axial ends of the connecting column 120, and are respectively used to be arranged on both sides of the battery compartment 200, so as to reasonably use the space on both sides of the battery compartment 200 in the axial direction of the connecting column 120. The elastic member 130 is surrounded by the connecting column 120, and one end of the elastic member 130 is abutted against the blocking member 140, and the other end of the elastic member 130 is used to abut against the battery compartment 200. The elastic member 130 is elastic and can provide a driving force for the locking member 110 to press against the battery module 30. 0 pre-tightening force, so that when the locking structure 100 locks the battery module 300, the elastic member 130 can apply a force along the axial direction of the connecting column 120 to the blocking member 140, so that the locking member 110 has a tendency to move toward the direction close to the battery module 300, and then the locking member 110 can continue to press against the surface of the battery module 300 to lock the battery module 300 at all times. The method of locking the battery module 300 is simple, which improves the stability and reliability of the locking structure 100 in locking the battery module 300.

[0061] In this embodiment, the connecting column 120 is used to be rotatably connected to the battery compartment 200, and the locking member 110 is used to move along the axial direction of the connecting column 120 under the action of external force, and drive the blocking member 140 to move to compress the elastic member 130. The locking member 110 is also used to rotate around the connecting column 120 between an unlocked position and a locked position under the action of external force.

[0062] It can be understood that the axial direction of the connecting column 120 is defined as the front-to-back direction. When the locking member 110 rotates from the locking position to the unlocking position, an external force is first applied to the locking member 110 to cause it to move in a direction away from the battery module 300, so that the locking member 110 moves toward the front of the battery module 300, thereby driving the connecting column 120 and the blocking member 140 to move forward. At this time, the blocking member 140 can compress the elastic member 130 forward; then an external force is applied to the locking member 110 to drive it to rotate, and the locking member 110 can be rotated from the locking position to the unlocking position. The unlocking method is simple. At this time, the external force on the locking member 110 is removed, and the elastic member 130 can elastically act on the blocking member 140, so that the blocking member 140 moves backward, driving the locking member 110 to move backward and press against the battery compartment 200.

[0063] When the locking member 110 is rotated from the unlocked position to the locked position, an external force is first applied to the locking member 110 to cause it to move in a direction away from the battery compartment 200, so that the locking member 110 moves toward the front of the battery compartment 200, and then an external force is applied to the locking member 110 to drive it to rotate. The locking member 110 can be rotated from the unlocked position to the locked position. The locking method is simple. At this time, the external force on the locking member 110 is removed, and the elastic member 130 can elastically act on the blocking member 140, so that the blocking member 140 moves backward, driving the locking member 110 to move backward and press against the battery module 300.

[0064] It should be understood that when the locking structure 100 of the embodiment of the present application is used to lock or unlock the battery compartment 200 and the battery module 300 in the battery compartment module 10, the locking method and the unlocking method are simple. Among them, two locking structures 100 with the same structure respectively continuously lock the left and right sides of the battery module 300, which can improve the locking stability and reliability of the battery module 300 and the battery compartment 200, effectively avoid the phenomenon that the battery module 300 is loosened from the battery compartment 200 when the robot encounters frequent bumps during walking, and improve the reliability of the robot.

[0065] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the locking member 110 includes a first locking portion 111, a connecting portion 112, and a second locking portion 113 which are sequentially connected along the radial direction of the connecting column 120, and the connecting portion 112 is connected to an end of the connecting column 120 away from the blocking member 140; when the locking member 110 is driven to rotate to the locking position and the external force on the locking member 110 is removed, the blocking member 140 drives the connecting column 120 and the connecting portion 112 to move under the pushing action of the elastic member 130, so that the first locking portion 111 is pressed against the surface of the battery module 300.

[0066] In this embodiment, the locking member 110 includes a first locking portion 111, a second locking portion 113 and a connecting portion 112. Along the radial direction of the connecting column 120, the first locking portion 111 and the second locking portion 113 are respectively connected to the two sides of the connecting portion 112, thereby simplifying the structure of the locking member 110. When the locking member 110 is driven to rotate to the locking position by an external force and the external force on the locking member 110 is removed, the elastic member 130 stretches and pushes the blocking member 140 to move backward along the axial direction of the connecting column 120, driving the connecting column 120 and the connecting portion 112 to move backward, thereby the first locking portion 111 and the second locking portion 113 move backward and press against the battery module 300 and the battery compartment 200 respectively.

[0067] Combination Figure 6 In a specific embodiment, the first locking portion 111 and the second locking portion 113 are integrally formed and connected to both ends of the connecting portion 112 to simplify the structure of the locking member 110 and improve the structural stability of the locking member 110.

[0068] like Figure 5 and Figure 6 As shown, in some embodiments, the locking member 110 is provided with an opening 114, and the radial direction of the opening 114 is parallel to the axial direction of the connecting column 120. In this embodiment, the opening 114 is provided on the locking member 110 for a finger to pass through, so as to facilitate applying an external force to the locking member 110 to pull the locking member 110 away from the battery compartment 200 to rotate the locking member 110. In a specific embodiment, the opening 114 is provided on the connecting portion 112, and the opening 114 is a round hole, which is convenient for a finger to pass through.

[0069] like Figure 6 As shown, in a specific embodiment, the connecting column 120 is provided with a first fixing hole 121 along its axis, and the blocking member 140 is provided with a second fixing hole 141 along its axis, and a screw is passed through the second fixing hole 141 and the first fixing hole 121 in sequence to fix the blocking member 140 to an end of the connecting column 120 away from the locking member 110. The blocking member 140 is a blocking sheet.

[0070] like Figure 1 and Figure 5 As shown, in a specific embodiment, the elastic member 130 is a spring, and the two ends of the spring can respectively support the battery compartment 200 and the baffle to provide elastic preload force, thereby eliminating the gap between the battery module 300 and the battery compartment 200 in the front-to-back direction of the battery module 300, and effectively preventing the battery module 300 from shaking when the robot is running in a bumpy manner.

[0071] like Figure 1 and Figure 2As shown, the embodiment of the present application also provides a battery compartment module 10, which includes a battery compartment 200, a battery module 300 and the two above-mentioned locking structures 100, and the battery module 300 is accommodated in the battery compartment 200; the two locking structures 100 are respectively arranged on opposite sides of the battery compartment 200 to lock or unlock the battery module 300 in the battery compartment 200.

[0072] It can be understood that a cavity for accommodating the battery module 300 is formed in the battery compartment 200 to accommodate the battery module 300 in the battery compartment 200. Since the battery compartment module 10 of the embodiment of the present application uses the above-mentioned locking structure 100 and the two locking structures 100 are respectively arranged on the opposite sides of the battery compartment 200, the two locking structures 100 with the same structure respectively continuously lock the left and right sides of the battery module 300, which can improve the locking stability and reliability of the battery module 300 and the battery compartment 200, and effectively avoid the phenomenon that the battery module 300 is loosened from the battery compartment 200 when the robot encounters frequent bumps during walking, thereby improving the reliability of the robot. At the same time, the method of locking the battery module 300 and the battery compartment 200 is simple, and the method of unlocking the battery module 300 and the battery compartment 200 is simple.

[0073] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, two mounting seats 210 are respectively provided on opposite sides of the battery compartment 200, and the two locking structures 100 are respectively installed on the two mounting seats 210. Each mounting seat 210 is provided with a mounting hole 211 for the connecting column 120 to pass through. The locking member 110 can drive the connecting column 120 to rotate relative to the mounting seat 210 in the mounting hole 211 under the action of external force. The end of the elastic member 130 away from the blocking member 140 is abutted against a side of the mounting seat 210 away from the locking member 110. The blocking member 140 is arranged between the blocking member 140 and the mounting seat 210, and the space between the mounting seat 210 and the blocking member 140 is reasonably used.

[0074] like Figure 1 and Figure 6 As shown, in some embodiments, two first grooves 310 are provided on one side of the battery module 300 facing the locking structure 100, and the two first grooves 310 correspond one-to-one to the two locking structures 100, and the locking member 110 has a first locking portion 111; when the locking member 110 is in the locking position, the first locking portion 111 is accommodated in the first groove 310, and the first locking portion 111 is pressed against the first groove 310 along the axial direction of the connecting column 120, and at the same time, in the circumferential direction of the connecting column 120, the side wall of the first locking portion 111 forms a gap with the side wall of the first groove 310, and the side wall of the first groove 310 is used to limit the circumferential rotation of the first locking portion 111 along the connecting column 120.

[0075] In this embodiment, two first grooves 310 are arranged on the front end surface of the battery module 300, and the two first grooves 310 and the two locking structures 100 correspond one to one in number. When the locking member 110 is in the locking position, the first locking portion 111 of the locking member 110 is pressed against the bottom surface of the first groove 310 along the axial direction of the connecting column 120 to limit the battery module 300 from escaping the battery compartment 200 forward; at the same time, in the circumferential direction of the connecting column 120, the side wall of the first locking portion 111 is gap-matched with the inner side wall of the first groove 310, and the inner side wall of the first groove 310 can limit the circumferential rotation of the first locking portion 111 along the connecting column 120, effectively ensuring that when the locking member 110 is in the locking position, the first locking portion 111 is always in contact with the first groove 310, and effectively avoiding the first locking portion 111 of the locking member 110 from being misaligned relative to the first groove 310 when in the locking position.

[0076] like Figures 1 to 4 As shown, combined with Figure 6 In some embodiments, two second grooves 220 are respectively provided on opposite sides of the battery compartment 200, and the two second grooves 220 are respectively connected to the two first grooves 310 to form two locking grooves 400, and the two locking grooves 400 correspond one by one to the two locking structures 100; the locking member 110 also has a second locking portion 113, and when the locking member 110 is in the locking position, the second locking portion 113 is pressed against the second groove 220 along the axial direction of the connecting column 120; when the locking member 110 is in the locking position, the locking member 110 is accommodated in the locking groove 400.

[0077] In this embodiment, two second grooves 220 are respectively provided on the opposite sides of the battery compartment 200. The two first grooves 310 can be understood as being arranged along the left and right directions of the battery module 300. The locking member 110 also has a second locking portion 113. When the locking member 110 is in the locking position, the second locking portion 113 is pressed against the second groove 220 along the axial direction of the connecting column 120, thereby increasing the pre-tightening force of the locking member 110 to lock the battery module 300 and the battery compartment 200. The locking grooves 400 are used to lock the locking member 110. In addition, the two second grooves 220 are connected to the two first grooves 310 to form two locking grooves 400. When the locking member 110 is in the locking position, the locking member 110 is accommodated in the locking grooves 400. At this time, in the rotation direction of the locking member 110, the two side surfaces of the locking member 110 are respectively matched with the two inner side wall gaps of the locking grooves 400.
