The installation and disassembly of the battery box on the surfboard body are realized, and the installation and disassembly structure is simple and convenient. The installation and disassembly difficulty of the battery box is greatly reduced, and the user can conveniently install and disassemble the battery box on the surfboard body.

[0035] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, a pull ring 150 is further included, which is arranged on the second surface of the upper cover 112 and connected with the connecting rod 140. It can be understood that the pull ring 150 is in the form of a ring body and is arranged on the second surface of the upper cover 112. The pull ring 150 can be used as a force point. A user can pull the pull ring 150 to stably drive the connecting rod 140 to slide up and down in the movable hole 112a, so as to drive the clamping piece 130 to be clamped or separated from the locking groove 121, thereby achieving the locking and unlocking of the battery box 110. The user can avoid the situation that the connecting rod 140 is easily separated from the hand when directly pulling the connecting rod 140, and the safety and convenience of the installation and disassembly of the battery box are further improved. In the embodiment, the second surface of the upper cover 112 is provided with a containing groove 112b, and the pull ring 150 is contained in the containing groove 112b. In this way, the pull ring 150 can be arranged on the second surface of the upper cover 112 without protruding. When surfing, the pull ring 150 is directly impacted by seawater, thereby protecting the pull ring 150 to a certain extent. Meanwhile, the structure is compact, and the outer surface of the battery box is more smooth and neat.

[0036] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In one embodiment, a connecting shaft 160 is further included. The pull ring 150 is provided with a connecting portion 151, the connecting portion 151 is provided with a first mounting hole 151a, the connecting rod 140 is provided with a second mounting hole, and the connecting shaft 160 is arranged in the first mounting hole 151a and the second mounting hole and is rotationally connected with the inner side wall of the first mounting hole 151a and the inner side wall of the second mounting hole. It can be understood that the pull ring 150 is provided with the connecting portion 151 at one end close to the connecting rod 140. The connecting portion 151 is provided with the first mounting hole 151a. One end of the connecting rod 140 protruding outward from the second surface of the upper cover 112 is provided with the second mounting hole. The connecting shaft 160 is arranged in the first mounting hole 151a and the second mounting hole to connect the pull ring 150 and the connecting rod 140 in series, thereby achieving the connection between the pull ring 150 and the connecting rod 140. The structure is simple and easy to install and form.

[0037] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9In one embodiment, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is greater when the pull ring 150 is perpendicular to the second surface of the upper cover 112 than when the pull ring 150 is parallel to the second surface of the upper cover 112. It can be understood that in this embodiment, the connecting portion 151 is provided in a flat structure, so that the height of the connecting portion 151 is greater than the thickness. By arranging the connecting shaft 160 at the end of the connecting portion 151 of the pull ring 150 away from the upper cover 112, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is greater when the pull ring 150 is perpendicular to the second surface of the upper cover 112, so that the connecting rod 140 drives the clamping piece 130 away from the locking groove 121, and the battery box is in the unlocking state. When the pull ring 150 is parallel to the second surface of the upper cover 112, the connecting portion 151 is thin, which greatly reduces the distance between the connecting rod 140 and the second surface of the upper cover 112, so that the connecting rod 140 drives the clamping piece 130 to approach and be clamped into the locking groove 121, and the battery box is in the locking state. That is, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is different when the pull ring 150 is perpendicular or parallel to the second surface of the upper cover 112, and the distance between the connecting shaft 160 and the second surface of the upper cover 112 is greater when the pull ring 150 is perpendicular to the second surface of the upper cover 112 than when the pull ring 150 is parallel to the second surface of the upper cover 112. Since the connecting shaft 160 is connected to the connecting rod 140, the connecting rod 140 can be driven to approach or move away from the second surface of the upper cover 112, so as to drive the connecting rod 140 to slide up and down, thereby driving the clamping piece 130 to move up and down in the accommodating cavity 111a, and to be clamped into or separated from the locking groove 121 of the locking piece 120, so as to realize the locking or unlocking. Thus, the pull ring 150 can be rotated to be perpendicular or parallel to the second surface of the upper cover 112, so as to realize the locking or unlocking of the battery box.

[0038] Further, in the embodiment, by defining the distance between the connecting shaft 160 and the second surface of the upper cover 112 when the pull ring 150 is perpendicular to the second surface of the upper cover 112 as L, and defining the distance between the connecting shaft 160 and the second surface of the upper cover 112 when the pull ring 150 is parallel to the second surface of the upper cover 112 as M, by setting the distance difference value of L-M to be the same as the distance of the clamping piece 130 moving into the locking groove 121, in this way, the vertical and parallel state of the pull ring 150 and the upper cover 112 can be switched by rotating the pull ring 150, so as to quantitatively move the movement distance of the connecting rod 140, and quantitatively move the movement distance of the clamping piece 130, accurately control the clamping piece 130 to be clamped into or separated from the locking groove 121, facilitate the user to accurately lock and unlock the battery box, so as to accurately realize the installation or disassembly of the battery box on the surfboard main body 200, and the operation is simple, which greatly reduces the installation and disassembly difficulty of the user.

[0039] Please refer to Figure 8 and Figure 9 In one embodiment, the connecting part 151 is provided with an abutting surface 151b away from one end of the pull ring 150, and the abutting surface 151b is in movable abutment with the second surface of the upper cover 112. It can be understood that the end of the connecting part 151 close to the second surface of the upper cover 112 is provided with the abutting surface 151b, and the abutting surface 151b can be attached to the second surface of the upper cover 112, so that when the pull ring 150 is perpendicular to the second surface of the upper cover 112, the abutting surface 151b can be attached to the second surface of the upper cover 112, so that the pull ring 150 can be stably in the state of being perpendicular to the second surface of the upper cover 112, avoiding the occurrence of skewing during the process of taking out the battery box, so as to ensure that the connecting shaft 160 drives the connecting rod 140 to move upward, thereby driving the clamping piece 130 to move upward away from the locking groove 121, achieving unlocking, thereby facilitating the user to smoothly take the battery box off the surfboard main body 200.

[0040] Please refer to Figure 8 and Figure 9 In one embodiment, the two side walls of the connecting part 151 are respectively provided with an arc surface 151c, and the abutting surface 151b is respectively adjacent to the two arc surfaces 151c. It can be understood that by providing each one of the arc surfaces 151c on the two sides of the abutting surface 151b, the smooth transition surface can be formed on the two sides of the abutting surface 151b, and when the user pushes the pull ring 150 to rotate, the pull ring 150 can be smoothly rotated through the arc surface 151c, avoiding hard contact between the pull ring 150 and the second surface of the upper cover 112, avoiding causing wear, and protecting the pull ring 150, while facilitating to improve the comfort of the user when rotating the pull ring 150, facilitating the user to lock and unlock by rotating the pull ring 150.

[0041] Please refer to Figure 8 and Figure 9 In one embodiment, the cross-sectional area of the connecting portion 151 gradually increases from one end close to the second surface of the upper cover 112 to one end away from the second surface of the upper cover 112. It can be understood that by setting the connecting portion 151 to be tapered, with the end close to the upper cover 112 being smaller and gradually increasing away from the upper cover 112, the end of the connecting portion 151 in contact with the second surface of the upper cover 112 is smaller, and when the pull ring 150 is perpendicular to the second surface of the upper cover 112, the contact area 151b of the connecting portion 151 in contact with the second surface of the upper cover 112 is smaller, and the force is concentrated. Without the action of external force, the pull ring 150 and the upper cover 112 can be stably kept perpendicular to each other, so that the clamping piece 130 and the locking piece 120 are in a disengaged state, ensuring the normal operation of unlocking. At the same time, since the connecting portion 151 is set to be tapered, the end of the connecting portion 151 away from the second surface of the upper cover 112 is larger, and when the user pushes the pull ring 150 to rotate downward, the end of the connecting portion 151 away from the upper cover 112 has a larger gravity, which can quickly pull the pull ring 150 to tilt and fall on the second surface of the upper cover 112, so that the pull ring 150 quickly fits and is parallel to the second surface of the upper cover 112, quickly realizing the locking state. In addition, the user can easily lock the battery box by adding the gravity of the connecting portion 151 itself to the external pushing force, realizing quick locking, saving the user's external force input, making the user can easily and labor-savingly lock the battery box, further reducing the difficulty of the user to lock and unlock the battery box, greatly improving the installation efficiency, and the operation is more simple.

[0042] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, a limiting member 170 is further included, which is arranged in the accommodating cavity 111a, and the limiting member 170 is provided with a limiting slot 171, which is communicated with the locking groove 121. The connecting rod 140 is provided with a guide surface 141, which is gradually arranged in a direction away from the locking groove 121 from one end close to the upper cover 112 to the other end. The clamping member 130 is movably arranged in the limiting slot 171, and the clamping member 130 is guided by the guide surface 141 to be close to or away from the locking groove 121. It can be understood that, in the embodiment, the limiting member 170 is arranged in the accommodating cavity 111a, and the limiting slot 171 is arranged in the limiting member 170 to accommodate the clamping member 130 and limit the movement of the clamping member 130, so as to prevent the clamping member 130 from moving out of the limiting slot 171 and over-traveling. In addition, the limiting slot 171 and the locking groove 121 are arranged adjacent to each other and communicated with each other, so that the clamping member 130 can be clamped into or separated from the locking groove 121 through the limiting slot 171. Specifically, the end of the connecting rod 140 close to the clamping member 130 is provided with the inclined guide surface 141, and the up-down movement of the connecting rod 140 drives the up-down movement of the guide surface 141. Since the guide surface 141 has an inclination, the up-down movement of the guide surface 141 can change the distance between the guide surface 141 and the locking groove 121, and the distance between the guide surface 141 and the locking groove 121 gradually increases along the upward movement direction of the guide surface 141. Therefore, under the guidance of the guide surface 141, the clamping member 130 moves in the limiting slot 171 and is close to or away from the locking groove 121, so as to realize the locking and unlocking states of the battery box, and the structure is simple and convenient to install and operate.

[0043] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In one embodiment, the cross-sectional area of the locking groove 121 gradually increases from the end away from the limiting slot 171 to the end close to the limiting slot 171. The locking groove 121 is arranged in a semicircular shape. It can be understood that, since the locking groove 121 is arranged in a semicircular shape, a smooth groove side wall structure can be formed, which can play a certain sliding pushing role when the battery box is taken out to drive the connecting rod 140 and the clamping member 130 to separate from the locking groove 121, so as to promote the clamping member 130 to separate from the locking groove 121, ensure the smooth separation of the clamping member 130, improve the smoothness of the unlocking of the battery box, ensure the smooth disassembly of the battery box from the surfboard body 200, have good practicability, reduce friction and abrasion, and play a certain protection role on the clamping member 130 and the locking member 120, which is beneficial to improving the service life of the whole battery box.

[0044] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 In one embodiment, the elastic member 180 is provided at one end of the upper cover 112 and at the other end of the connecting rod 140, and the elastic member 180 is in a compressed state.

In this way, the elastic member 180 can form a downward pulling force on the connecting rod 140 by the pre-tightening force of the elastic member 180. When the pull ring 150 is pulled to the vertical state, the connecting rod 140 moves upward under the driving of the pull ring 150, further compressing the elastic member 180. At this time, since the pull ring 150 and the second surface of the upper cover 112 are perpendicular to each other, the pre-tightening force of the elastic member 180 acts on the pull ring 150 through the connecting rod 140 to form a vertical downward pulling force, which can prevent the pull ring 150 from moving randomly. After the user lifts the pull ring 150 to the vertical state, the clamping piece 130 can be stably in the unlocked state, thereby facilitating the user to further remove the battery box from the surfboard body 200.

[0045] In addition, when the user pushes down the pull ring 150 to make the pull ring 150 parallel to the second surface of the upper cover 112 to lock, the connecting rod 140 moves downward, so that the elastic member 180 is released, and the pre-tightening force of the elastic member 180 can pull the pull ring 150. The user can save more external force and easily complete the locking. The elastic member 180 is always in a compressed state, which can continuously pull the pull ring 150 downward to prevent the pull ring 150 from turning up when surfing due to the impact of seawater. It can ensure that the battery box is stably locked and installed on the surfboard body 200, avoids falling off, greatly improves the safety and stability of the battery box installation, and has good practicability.
