The clamping member 130 is movably provided in the locking groove 121. The connecting rod 140 is slidably inserted into the movable hole 112a, and the connecting rod 140 at least partially protrudes through the movable hole 112a and is arranged on the outer side of the second surface of the upper cover 112. The connecting rod 140 is connected to the clamping member 130, and the connecting rod 140 is used to drive the clamping member 130 to approach or move away from the locking groove 121, so that the clamping member 130 is clamped into or disengaged from the locking groove 121.

[0033] It should be noted that the box body 110 is configured as a detachable bottom shell 111 and an upper cover 112 structure. The bottom shell 111 is a shell-like structure and is provided with a receiving cavity 111a. The receiving cavity 111a can be used to receive a battery, and the battery is used to power a driving device of the electric hydrofoil surfboard. The shape of the upper cover 112 is adapted to the shape of the bottom shell 111. A side of the upper cover 112 close to the bottom shell 111 is a first side, and a side of the upper cover 112 away from the bottom shell 111 is a second side. The first side and the second side of the upper cover 112 are arranged opposite to each other. The upper cover 112 is used to cover the bottom shell 111 and seal the receiving cavity 111a. Specifically, the upper cover 112 is threaded with a threaded hole provided in the bottom shell 111 through a bolt. The upper cover 112 is connected to the bottom shell 111 to realize a detachable connection with the bottom shell 111, which is convenient for disassembly and installation.

The upper cover 112 is provided with an active hole 112a that runs through the first surface and the second surface of the upper cover 112, which is used for movably installing the connecting rod 140. The hole circumference of the active hole 112a is sealed, for example, a sealing ring is provided on the inner wall of the active hole 112a for sealing, so as to ensure that the connecting rod 140 is movable while playing a sealing role to prevent seawater from passing through. The movable hole 112a enters the accommodating cavity 111a, the connecting rod 140 is inserted into the movable hole 112a, and is slidably connected to the inner side wall of the movable hole 112a. The connecting rod 140 is connected to the clamping member 130. Specifically, the connecting rod 140 and the clamping member 130 are driven and driven. The connecting rod 140 and the clamping member 130 can be fixedly connected or movably connected. By pulling the connecting rod 140 to slide up and down in the movable hole 112a, the clamping member 130 is driven to move back and forth close to or away from the locking groove 121 of the locking member 120. At the same time, the locking member 120 is installed on the surfboard body 200. The locking member 120 is provided with a locking groove 121. When the battery box is placed When installed on the surfboard body 200, the clamping member 130 is aligned above the locking member 120, and the clamping member 130 is driven to move close to the locking groove 121 by sliding the connecting rod 140, so that the clamping member 130 is engaged in the locking groove 121 to achieve locking, thereby the battery box is clamped and fixedly installed on the surfboard body 200. When the battery box needs to be removed from the surfboard body 200, the connecting rod 140 is slid in the reverse direction to drive the clamping member 130 away from the locking groove 121 and slide out of the locking groove 121, so that the clamping member 130 is separated from the locking member 120, thereby achieving unlocking, and the battery box is removed from the surfboard body 200, which is convenient for installation and disassembly.

[0034] Furthermore, in this embodiment, the clamping member 130 is installed in the accommodating cavity 111a, and a positioning hole 111b is provided at the bottom of the bottom shell 111. The locking member 120 installed on the surfboard body 200 is inserted into the accommodating cavity 111a through the positioning hole 111b. The circumference of the positioning hole 111b is sealed. For example, a sealing ring is provided on the inner wall of the positioning hole 111b for sealing, so as to ensure that the locking member 120 is movably inserted into the positioning hole 111b and achieve sealing, thereby preventing seawater from entering the accommodating cavity 111a through the positioning hole 111b, and protecting the parts inside the accommodating cavity 111a. The locking member 120 can be inserted into the positioning hole 111b to realize the positioning and installation of the battery box. At the same time, the locking member 120 protrudes through the positioning hole 111b and is arranged in the accommodating cavity 111a. The locking member 120 is locked with the clamping member 130 inside the accommodating cavity 111a. The structure is compact, and the locking member 120 and the clamping member 130 can be sealed inside the accommodating cavity 111a, which can protect the locking member 120 and the clamping member 130, thereby improving the overall structural stability and service life of the battery box. The locking member 120 and the clamping member 130 may be provided with a plurality of them, and each locking member 120 and each clamping member 130 are provided in a one-to-one correspondence. In this way, the battery box can be more firmly installed on the surfboard body 200 by locking multiple sets of locking members 120 and clamping members 130. For example, the locking member 120 and the clamping member 130 may be provided with two, so that the battery box can be locked and fixed on the surfboard body 200 at the left and right ends, and the installation effect is good. Specifically, the clamping member 130 is driven to approach or move away from the locking member 120 by the connecting rod 140, so that the clamping member 130 and the lock member 130 are locked. The fastener 120 is clamped and locked together or disengaged from the locking member 120, thereby locking the box body 110 to the surfboard body 200 or disengaging from the surfboard, and the connecting rod 140 is protruded from the outer side of the second surface of the upper cover 112, so that the user can pull the connecting rod 140 on the outer surface of the upper cover 112 to achieve the engagement or disengagement of the clamping member 130 and the locking member 120, thereby achieving the installation and removal of the battery box on the surfboard body as a whole, the installation and removal structure is simple, the installation and removal are simple, the difficulty of installing and removing the battery box is greatly reduced, and the user can install and remove the battery box on the board body conveniently.

[0035] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, a pull ring 150 is further included, and the pull ring 150 is disposed on the second surface of the upper cover 112, and the pull ring 150 is connected to the connecting rod 140. It can be understood that by providing the pull ring 150, the pull ring 150 is a ring-shaped structure, the pull ring 150 is used to connect with the connecting rod 140, and the pull ring 150 is disposed on the second surface of the upper cover 112. The pull ring 150 can be used as a fulcrum. The user can pull the pull ring 150 to more smoothly drive the connecting rod 140 to slide up and down in the movable hole 112a, thereby driving the clamping member 130 to engage or disengage from the locking groove 121, thereby realizing the locking and unlocking of the battery box 110, and avoiding the user from directly The connecting rod 140 may easily slip out of the hand when being pulled, which further improves the safety and convenience of installing and removing the battery box. In this embodiment, a receiving groove 112b is provided on the second side of the upper cover 112, and the pull ring 150 is received in the receiving groove 112b. In this way, the pull ring 150 can be prevented from protruding from the second side of the upper cover 112. When surfing, the pull ring 150 can be prevented from being directly impacted by sea water, which provides a certain degree of protection for the pull ring 150. At the same time, the structure is compact and the outer surface of the battery box is smoother and tidier.

[0036] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9 In one embodiment, it further includes a connecting shaft 160, 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, the connecting shaft 160 is inserted into the first mounting hole 151a and the second mounting hole, and is rotatably 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 end of the pull ring 150 close to the connecting rod 140 is provided with a connecting portion 151, the connecting portion 151 is provided with a first mounting hole 151a, and the end of the connecting rod 140 protruding from the outer side of the second surface of the upper cover 112 is provided with a second mounting hole. By providing the connecting shaft 160, the connecting shaft 160 is inserted into the first mounting hole 151a and the second mounting hole, the pull ring 150 and the connecting rod 140 are connected in series, thereby realizing the connection between the pull ring 150 and the connecting rod 140, and the structure is simple and easy to install and form.

[0037] See also Figure 6 , Figure 7 , Figure 8 and Fig. 9In one embodiment, when the pull ring 150 and the second surface of the upper cover 112 are perpendicular to each other, the distance between the connecting axis 160 and the second surface of the upper cover 112 is greater than the distance between the connecting axis 160 and the second surface of the upper cover 112 when the pull ring 150 and the second surface of the upper cover 112 are parallel to each other. It can be understood that in the present embodiment, the connecting portion 151 is configured as a flat structure, so that the height of the connecting portion 151 can be larger 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, when the pull ring 150 is perpendicular to the second surface of the upper cover 112, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is large, so that the connecting rod 140 drives the clamping member 130 away from the locking groove 121, and it is in an unlocked state at this time. When the pull ring 150 is parallel to the second surface of the upper cover 112, since the connecting portion 151 is thin, the distance between the connecting rod 140 and the second surface of the upper cover 112 is greatly reduced, so that the connecting rod 140 drives the clamping member 130 to approach and snap into the locking groove 121, and it is in a locked state at this time. That is to say, the pull ring 150 can be perpendicular or parallel to the upper cover. When the pull ring 150 is perpendicular to the second surface of the upper cover 112, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is different, and when the pull ring 150 is perpendicular to the second surface of the upper cover 112, the distance between the connecting shaft 160 and the second surface of the upper cover 112 is greater than the distance between the connecting shaft 160 and the second surface of the upper cover 112 when the pull ring 150 and the second surface of the upper cover 112 are parallel to each other. 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, thereby driving the connecting rod 140 to slide up and down, thereby driving the clamping member 130 to move up and down inside the accommodating cavity 111a, and clamping into or disengaging from the locking groove 121 of the locking member 120, thereby realizing locking or unlocking. In this way, the pull ring 150 can be rotated so that the pull ring 150 is respectively in a state perpendicular or parallel to the second surface of the upper cover 112, thereby realizing the locking or unlocking state of the battery box.

[0038] Further, in the present embodiment, by defining the distance between the connecting shaft 160 and the second surface of the upper cover 112 when the pull ring 150 and the second surface of the upper cover 112 are perpendicular to each other 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 and the second surface of the upper cover 112 are parallel to each other as M, and by setting the distance difference value of LM to be the same as the distance by which the clamping member 130 moves into the locking groove 121, the pull ring 150 can be switched between the perpendicular and parallel states with the upper cover 112 by rotating the pull ring 150, thereby quantitatively moving the moving distance of the connecting rod 140, thereby quantitatively moving the moving distance of the clamping member 130, and accurately controlling the clamping member 130 to be clamped into or out of the locking groove 121, so that the user can accurately lock and unlock the battery box, thereby accurately realizing the installation or removal of the battery box on the surfboard body 200, and the operation is simple, which greatly reduces the installation and removal difficulty of the user.

[0039] See also Figure 8 and Fig. 9 In one embodiment, the end of the connection part 151 away from the pull ring 150 is provided with a supporting surface 151b, and the supporting surface 151b is movably abutted against the second surface of the upper cover 112. It can be understood that the end of the connection part 151 close to the second surface of the upper cover 112 is provided with a supporting surface 151b, and the supporting surface 151b can be in contact with the second surface of the upper cover 112. In this way, when the pull ring 150 is rotated to be perpendicular to the second surface of the upper cover 112, the supporting surface 151b can be in contact with the second surface of the upper cover 112, so that the pull ring 150 is stably in a state of being perpendicular to the second surface of the upper cover 112, avoiding the situation of being skewed in the process of taking out the battery box, so that the connecting shaft 160 can drive the connecting rod 140 to move upward, thereby driving the clamping member 130 to move upward away from the locking groove 121, and unlocking is achieved, so that the user can smoothly remove the battery box from the surfboard body 200.

[0040] See also Figure 8 and Fig. 9 In one embodiment, the side walls of the connecting portion 151 are respectively provided with an arc surface 151c, and the abutting surface 151b is adjacent to the two arc surfaces 151c. It can be understood that by providing an arc surface 151c on both sides of the abutting surface 151b, a smooth transition surface can be formed on both sides of the abutting surface 151b. When the user pushes the pull ring 150 to rotate, the pull ring 150 can rotate smoothly through the arc surface 151c, avoiding hard contact between the pull ring 150 and the second surface of the upper cover 112, avoiding wear and tear, and protecting the pull ring 150. At the same time, it is conducive to improving the user's comfort when rotating the pull ring 150, and it is convenient for the user to lock and unlock by rotating the pull ring 150.

[0041] See also Figure 8 and Fig. 9 In one embodiment, the cross-sectional area of ​​the connection portion 151 gradually increases from the end close to the second surface of the upper cover 112 to the end away from the second surface of the upper cover 112. It can be understood that by setting the connection portion 151 to be smaller at the end close to the upper cover 112 and gradually increasing in the direction away from the upper cover 112, the end of the connection portion 151 in contact with the second surface of the upper cover 112 can be made smaller. When the pull ring 150 is perpendicular to the second surface of the upper cover 112, the area of ​​the abutment surface 151b of the connection portion 151 in contact with the second surface of the upper cover 112 is small, and the force is concentrated. In the absence of external force, the pull ring 150 and the upper cover 112 can be stably maintained in a state of being perpendicular to each other, thereby ensuring that the clamping member 130 and the locking member 120 are in a disengaged state, ensuring normal unlocking. At the same time, since the connection portion 151 is set in a conical shape, the connection portion 151 is far away from the upper cover 112. The end away from the second surface of the upper cover 112 is larger. When the user pushes the pull ring 150 to rotate downward, the end of the connecting part 151 away from the upper cover 112 has a larger gravity, and the pull ring 150 can be quickly pulled to tilt down toward the second surface of the upper cover 112, so that the pull ring 150 and the second surface of the upper cover 112 are quickly fitted and parallel, and the locked state is quickly achieved. When the user locks the battery box, in addition to the external thrust, the gravity of the connecting part 151 itself is added to achieve quick locking, saving the user's external force input, allowing the user to 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 making the operation easier.

[0042] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, it also includes a limiting member 170, which is arranged in the accommodating cavity 111a. The limiting member 170 has a limiting groove 171, and the limiting groove 171 is communicated with the locking groove 121. The connecting rod 140 is provided with a guide surface 141, and the guide surface 141 is gradually inclined from one end close to the upper cover 112 to the other end toward a direction away from the locking groove 121. The clamping member 130 is movably arranged in the limiting groove 171, and the clamping member 130 is close to or away from the locking groove 121 under the guidance of the guide surface 141. It can be understood that in this embodiment, by setting a limiting member 170, the limiting member 170 is installed in the accommodating cavity 111a, and the limiting member 170 is provided with a limiting groove 171, and the limiting groove 171 is used to accommodate the clamping member 130, and the movement of the clamping member 130 is limited to prevent the clamping member 130 from escaping from the limiting groove 171 and over-travel movement. At the same time, the limiting groove 171 is adjacent to the locking groove 121 and is connected to each other. In this way, the clamping member 130 can be clamped into or out of the locking groove 121 through the limiting groove 171. Specifically, one end of the connecting rod 140 close to the clamping member 130 is provided with an inclined The inclined guide surface 141 drives the guide surface 141 to move up and down through the up and down movement of the connecting rod 140. Since the guide surface 141 has an inclination, the up and down movement of the guide surface 141 can change the distance between the guide surface 141 and the locking groove 121, and along the upward movement direction of the guide surface 141, the distance between the guide surface 141 and the locking groove 121 gradually increases, so that under the guidance of the guide surface 141, the clamping member 130 moves in the limiting groove 171 and approaches or moves away from the locking groove 121, thereby realizing the locking and unlocking state of the battery box, with a simple structure and easy installation and operation.

[0043] See also 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 groove 171 to the end close to the limiting groove 171. The locking groove 121 is set in a semicircular shape. It can be understood that the locking groove 121 is set in a semicircular shape, which can form a smooth groove side wall structure. When the battery box is taken out and the connecting rod 140 and the clamping member 130 are driven out of the locking groove 121, the smooth locking groove 121 structure can play a certain pushing and sliding role, promote the clamping member 130 to escape from the locking groove 121, ensure the smooth escape of the clamping member 130, improve the smoothness of the battery box unlocking, and ensure that the battery box is smoothly removed from the surfboard body 200. It has good practicality, reduces friction and wear, and can play a certain protective role on the clamping member 130 and the locking member 120, which is conducive to improving the overall service life of the battery box.

[0044] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 In one embodiment, it further includes an elastic member 180, one end of which is connected to the first surface of the upper cover 112, and the other end of which is connected to the connecting rod 140, and the elastic member 180 is in a compressed state. It can be understood that by providing the elastic member 180, in this embodiment, the elastic member 180 is a spring, which is a commonly used elastic member, and the spring is a hollow structure, so that the elastic member 180 can be directly sleeved on the connecting rod 140, and the elastic member 180 is compressed under the drive of the connecting rod 140, and the elastic member 180 is always in a compressed state. In this way, a downward pulling force can be formed on the connecting rod 140 through the pre-tightening force of the elastic member 180, and when the pull ring 150 is pulled to a vertical state, the connecting rod 140 is pulled downward. The connecting rod 140 moves upward under the drive 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 generated by the elastic member 180 exerts a vertical downward pulling force on the pull ring 150 through the connecting rod 140, which can prevent the pull ring 150 from moving at will, so that the user can lift the pull ring 150 to a vertical state, and the clamping member 130 can be stably in an unlocked state, so that the user can further remove the battery box from the surfboard body 200.

[0045] In addition, when the user pushes the pull ring 150 down so that the pull ring 150 is parallel to the second surface of the upper cover 112 for locking, the connecting rod 140 moves downward to release the elastic member 180. 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 exert a downward pulling force on the pull ring 150 to prevent the pull ring 150 from being flipped up and rotated due to the impact of sea water during surfing. This can ensure that the battery box is firmly locked and installed on the surfboard body 200 to avoid falling off, greatly improving the safety and stability of the battery box installation, and having good practicality.

[0046] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, the clamping member 130 is a ball. It can be understood that the clamping member 130 is set as a ball, which is rolled and installed in the limiting groove 171, and under the guidance of the guide surface 141, it rolls into or out of the locking groove 121 from the limiting groove 171. The clamping member 130 adopts a ball, which can convert the motion friction between the clamping member 130 and the inner wall of the locking groove 121 into rolling friction, greatly reducing the friction force, reducing wear, and improving the structural stability between the clamping member 130 and the locking member 120, thereby greatly improving the overall stability and service life of the battery box, and having good practicality. The clamping member 130 can also adopt other components that can be inserted into or out of the locking groove 121 under the drive of the connecting rod 140. For example, the clamping member 130 can also be a spring sheet, which is ejected into or out of the locking groove 121 under the drive of the connecting rod 140. This embodiment will not be described in detail.

[0047] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 In one embodiment, an anti-collision block 190 is further included, and the anti-collision block 190 is connected to the bottom of the bottom shell 111. It can be understood that by providing the anti-collision block 190, the anti-collision block 190 is installed at the bottom of the bottom shell 111. Since the locking member 120 may collide with the bottom shell 111 during the installation of the battery box, it is easy to cause damage to the bottom shell 111. By providing the anti-collision block 190, the locking member 120 can be prevented from directly colliding with the bottom shell 111, which plays a certain protective role. The anti-collision block 190 can be made of hard material to ensure the anti-collision effect. At the same time, the anti-collision block 190 can also be provided with a guide hole, which is connected with 111b to ensure that the locking member 120 passes through the guide hole and the positioning hole 111b to enter the accommodating cavity and is locked with the clamping member 130. Further, the guide hole is provided with a guide slope to facilitate the alignment of the locking member 120 during the installation process.

[0048] See also Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, it further includes a sleeve 191, which is detachably mounted on the first surface of the upper cover 112 and covers the outer side of the connecting rod 140, the clamping member 130 and the limiting member 170. It can be understood that by providing the sleeve 191, which is a hollow cylindrical structure and can be detachably mounted on the first surface of the upper cover 112 by bolts, the connecting rod 140, the clamping member 130 and the limiting member 170 can be accommodated and installed in the sleeve 191, which plays an installation limiting role for the connecting rod 140, the clamping member 130 and the limiting member 170, and can protect the connecting rod 140, the clamping member 130 and the limiting member 170, preventing the connecting rod 140, the clamping member 130 and the limiting member 170 from being damaged by collision, and the structural stability is better.
