Description
Technical Field
[0001] The utility model relates to a power supply device for an electric surfboard, in particular to a battery interface for an electric surfboard. Background Art
[0002] In order to facilitate the removal of charging and battery replacement, the electric surfboard uses a detachable battery module as a power supply. A dedicated battery interface is provided between the battery module and the battery compartment of the electric surfboard where it is placed. The battery interface includes a matching plug and socket, which are respectively arranged on the battery module and the battery compartment. After the battery module is placed in the battery compartment, the male and female of the plug and the socket match, and are sealed and waterproof after plugging. The battery interface of the existing electric surfboard puts the positive and negative poles together. Not only is the connector required for assembling the interface large and heavy, but the location of the interface will also conflict with the power supply wiring of the propeller. Specifically, the interface on the battery compartment will occupy the wiring space of the motor wiring in the propeller, making it difficult to wire the motor power supply. Utility Model Content
[0003] The technical problem to be solved and the technical task proposed by the utility model are aimed at the technical problem that the battery interface structure on the existing electric surfboard affects the output line of the motor inside the propeller and occupies the wiring space. The utility model provides an electric surfboard battery interface, the interface structure separates the positive and negative poles and arranges them on both sides, avoiding the output line of the motor inside the propeller corresponding to the middle position, freeing up space for the motor power supply wiring, and at the same time, the volume of a single positive / negative terminal is smaller and lighter, and the waterproof sealing effect is better.
[0004] The technical solution adopted by the utility model to solve the technical problem is: an electric surfboard battery interface, including a plug and a socket arranged between the battery module and the battery compartment interface, characterized in that the plug is composed of a separate positive plug and a negative plug, and the socket is composed of a separate positive socket and a negative socket. When the battery module is placed in the battery compartment, the two sets of matching formed by the positive and negative plugs and the positive and negative sockets are symmetrically arranged on both sides of the central axis of the electric surfboard. The utility model separates the positive and negative poles on the plug and the socket, and arranges them on both sides of the central axis of the electric surfboard, avoiding the outlet line of the propeller motor, leaving a gap in the middle for the motor wiring; and the size of the connector corresponding to the single plug or socket after the positive and negative poles are separated is also significantly reduced compared to the positive and negative poles combined together, and the smaller size is conducive to improving the waterproof sealing, so that the waterproof effect of the battery interface can be better.
[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: the positive and negative plugs are fixed on the battery compartment wall, and the positive and negative plugs are plugs with the same structure, and the plugs have a vertical conductive rod extending out; the positive and negative sockets are fixed at the bottom of the battery module, and the positive and negative sockets are sockets with the same structure, and the sockets have a conductive socket that can be tightly matched with the conductive rod, and when the plug and the socket are matched, the conductive rod is inserted into the conductive socket and waterproofed by a sealing ring. Not only the structures of the two plugs are the same, but also the structures of the two sockets are the same, which can improve the versatility of parts to achieve standardization and facilitate mass production and assembly; when the battery module and the battery compartment are matched, the conductive rod and the conductive socket are respectively at the bottom of the lower battery compartment and the upper battery module, and it is not easy for water to accumulate on the surface of the vertical conductive rod and inside the conductive socket with the opening facing downward, and waterproofing is achieved by a sealing ring when the conductive rod and the conductive socket are connected.
[0006] The plug forms a boss at the extended position of the conductive rod, and the sealing ring is a sealing cap with a top wall and a side wall. The sealing cap is sleeved on the extended section of the conductive rod through the opening on the top wall and is sleeved on the boss. The bottom of the socket is provided with a step hole that coincides with and communicates with the axis of the conductive jack. When the plug and the socket are mated, the conductive rod passes through the step hole and is inserted into the conductive jack, and the sealing cap is pressed between the boss and the wall of the step hole. As the conductive rod and the conductive jack are plugged and matched, the sealing cap is pressed between the boss and the wall of the step hole to achieve waterproof sealing of the mating of the plug and the socket. The sealing cap uses its top wall and side wall to seal from the radial direction and axial direction respectively to prevent the inflow of water from the outside from affecting the electrification of the interface.
[0007] The outer surface of the side wall of the sealing cap is provided with a ring tooth, which can form an interference fit with the inner wall of the step hole. The ring tooth and the inner wall of the step hole form an interference fit, thereby improving the sealing and waterproof effect of the sealing cap in the axial direction.
[0008] The outer surface of the top wall of the sealing cap is a plane, and the inner wall of the step hole is provided with a convex ring that contacts and matches the plane. The convex ring contacts the top wall of the sealing cap to improve the sealing and waterproofing effect of the sealing cap in the radial direction.
[0009] The radial distance between the side wall of the sealing cap and the conductive rod is b. After the plug and the socket are matched in place, the radial distance between the convex ring and the conductive rod is c, and 30% b≤c<b. By limiting the radial distance between the convex ring and the conductive rod, it is ensured that the convex ring contacts the top wall to press the sealing cap tightly. If the convex ring is too close to the conductive rod, the sealing cap will move relative to the conductive rod, thereby causing the sealing cap to deviate and affect the seal. If the convex ring is too far from the conductive rod, it will have less contact with the top wall and fail to press the sealing cap tightly.
[0010] The plug includes an insulating base fixedly connected to the battery compartment wall and a conductive rod vertically mounted thereon, the boss is arranged at the top of the base, the lower end of the conductive rod is placed behind the battery compartment wall and forms a plug connection terminal at the end, and the base is provided with a rod penetration hole for passing the conductive rod; the socket includes an insulating base fixedly connected to the bottom of the battery module and a conductive member with a conductive socket, the base forms a vertical tube with an open tubular cavity, the inner end of the vertical tube is placed in the battery module, and the outer end is placed outside the battery module, the conductive member is inserted into the tubular cavity from the inner end of the vertical tube and is fastened to the vertical tube, the outer end of the conductive member forms a socket connection terminal, and the step hole is arranged at the outer end of the vertical tube and is coaxially connected to the tubular cavity. The plug and the socket each include a conductive component and an insulating seat body to fix it. The power connection terminals on the two conductive components are also the ends of the conductive components, and are respectively hidden behind the battery compartment wall where the installation position is located and inside the battery module. The two conductive components are fixed by matching with the holes set on the corresponding seat bodies, wherein the conductive rod of the plug is passed through and fixed to the base, and the conductive part of the socket is plugged and fixed to the base. The step hole is arranged at the outer end of the vertical tube outside the battery module and coincides with the axis of the vertical tube cavity.
[0011] The rod-penetrating hole is composed of a small-diameter hole and a large-diameter hole that are connected up and down, and a step surface is formed at the diameter change. The conductive rod is formed by connecting rod segments and rod seats that are distributed up and down. The rod segment passes through the small-diameter hole from one side of the large-diameter hole and is fastened to the base, and the rod segment partially extends out of the small-diameter hole. The rod seat abuts against the step surface and matches the gap with the large-diameter hole. The outer end of the rod seat forms a plug connection terminal; the side surface of the boss and the side wall of the sealing cap of the outer sleeve are concave and convex. The rod-penetrating hole on the base is composed of two sections of channels, which are small at the top and large at the bottom, and a step surface is formed at the diameter change. The conductive rod is composed of an integrated rod segment and a rod seat. During installation, the rod segment passes through the large-diameter hole and the small-diameter hole in sequence, and partially extends out of the small-diameter hole. The rod segment fastens the conductive rod to the base by tightly matching with the small-diameter hole. After installation, the rod seat abuts against the step surface, and the gap between the rod seat and the large-diameter hole can be further sealed with glue.
[0012] The tube cavity of the vertical tube includes a conductive part insertion hole, a reduced diameter hole and a step hole which are connected from top to bottom. The diameter of the reduced diameter hole is smaller than that of the conductive part insertion hole and the step hole. The conductive part is fastened to the vertical tube by inserting into the conductive part insertion hole. The tube cavity is divided into three sections along the axial direction. The conductive part insertion holes and the step hole at both ends of the tube cavity are used to install the conductive rod and the sealing cap respectively. The reduced diameter hole is between the two and has the smallest hole diameter. A step surface is formed at the reduced diameter of the inner end of the conductive part insertion hole, which can limit the insertion depth by resisting the conductive part. A step surface is also formed at the reduced diameter of the inner end of the step hole, which is used to cooperate with and press the sealing cap.
[0013] The base is fixed to the battery compartment wall and sealed with a first sealing ring. The base is provided with an expanded diameter section to form a first mounting platform. The first mounting platform is fixed to the battery compartment wall surface by bolts. The first sealing ring is pressed between the first mounting platform and the battery compartment wall. The base is fixed to the bottom wall of the battery module shell and sealed with a second sealing ring. The base is provided with an expanded diameter section to form a second mounting platform. The second mounting platform is fixed to the bottom wall surface of the shell by bolts. The second sealing ring is pressed between the second mounting platform and the bottom wall of the shell. The base and the pedestal are respectively fixed to the battery compartment wall and the bottom wall of the battery module shell. The sealing rings are used for waterproofing at the inserted positions. For fixing, the base and the pedestal have an expanded diameter section to form a corresponding mounting platform. The two mounting platforms are fastened to the corresponding wall surface with bolts. The sealing rings are pressed between the corresponding mounting platform and the wall surface.
[0014] The utility model separates the positive and negative electrodes of the battery interface on the electric surfboard, specifically, the conductive connections of the positive and negative electrodes are symmetrically arranged on both sides of the central axis of the electric surfboard to avoid the motor output line of the propeller, leaving a middle installation space for the motor wiring; the size of the connector corresponding to the single plug or socket after the positive and negative electrodes are separated is also much smaller than that of the original positive and negative electrodes combined together, which helps to achieve better waterproof sealing, thereby improving the waterproof sealing effect of the battery interface.

DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0023] like Figure 1-6 The figure shows a battery interface of an electric surfboard, including a plug and a socket arranged between the mating surface of a battery module 19 and a battery compartment (not shown in the figure), the plug is composed of a positive plug and a negative plug, and the socket is also composed of a positive socket and a negative socket. When the battery module is placed in the battery compartment, the positive plug and the positive socket form a set of conductive matching, and the negative plug and the negative socket form a set of conductive matching. The two sets of matching are symmetrically arranged on both sides of the central axis of the electric surfboard. The positive plug and the negative plug in this embodiment are both fixed on the wall of the battery compartment. The two plugs are constructed as plugs 1 of the same structure, and the plug 1 has a vertical conductive rod 3 extending out; similarly, the positive socket and the negative socket are also fixed on the bottom of the battery module, and the two sockets are also sockets 2 of the same structure. The socket 2 has a conductive socket 4 that can be tightly fitted with the conductive rod 3. When the plug 1 and the socket 2 are matched, the conductive rod 3 is inserted into the conductive socket 4, and is sealed by a sealing ring to prevent water from outside from flowing in.
[0024] When in use, the positive and negative poles on the plug and socket are separated and arranged on both sides of the central axis of the electric surfboard, successfully avoiding the outlet line of the propeller motor and leaving a gap in the middle for the motor wiring; the size of the connector corresponding to the single plug or socket after separation can also be greatly reduced, which is conducive to improving waterproof sealing. Not only the two plugs have the same structure, but also the two sockets have the same structure, which can improve the versatility of parts and achieve standardization, and facilitate mass production and assembly; when the battery module and the battery compartment are matched, the conductive rod is in the battery compartment below, and the conductive socket is at the bottom of the battery module above. It is not easy for water to accumulate on the surface of the vertical conductive rod and the conductive socket with the opening facing downward. When the conductive rod and the conductive socket are connected, a sealing ring is used for waterproof sealing.
[0025] Furthermore, the plug 1 forms a boss 6 at the extended position of the conductive rod 3, and the sealing ring is a sealing cap 5 having a top wall 5-1 and a side wall 5-2. The outer surface of the top wall 5-1 of the sealing cap 5 is a plane. The sealing cap 5 is sleeved on the extended section of the conductive rod 3 through the opening on the top wall 5-1 and is sleeved on the boss 6. The outer surface of the side wall 5-2 of the sealing cap 5 is provided with a ring tooth 5-3. The bottom of the socket 2 is provided with a step hole 7 that coincides with and communicates with the axis of the conductive socket 4. The inner wall of the step hole 7 is provided with a convex ring 7-1. When the plug 1 and the socket 2 are matched, the conductive rod 3 passes through the step hole 7 and is inserted into the conductive socket 4, and the sealing cap 5 is pressed between the boss 6 and the wall of the step hole 7. At the same time, the ring tooth 5-3 forms an interference fit with the inner wall of the step hole 7, and the convex ring 7-1 presses against the plane of the top wall 5-1 of the sealing cap 5. As shown in the figure, the radial distance between the side wall 5-2 on the sealing cap 5 and the conductive rod 3 is b. After the plug 1 and the socket 2 are matched in place, the radial distance between the convex ring 7-1 and the conductive rod 3 is c, 30% b≤c<b. The sealing cap achieves radial and axial sealing effects by pressing its top wall and side wall, and plays a waterproof sealing role when the plug and the socket are matched, preventing the outside water from flowing in and affecting the power supply of the interface. The radial distance between the convex ring and the conductive rod is limited to ensure that the convex ring presses against the top wall to press the sealing cap. In order to avoid water on the surface of the top wall of the sealing cap when it is pressed, the periphery of the top wall is set as a curved surface 5-4 with a slope.
[0026] The plug 1 in this embodiment includes an insulating base 8 fixedly connected to the battery compartment wall and a conductive rod 3 vertically mounted thereon. The conductive rod 3 is formed by connecting a rod segment 3-2 and a rod seat 3-3 distributed up and down. The boss 6 is arranged on the top of the base 8. The lower end of the conductive rod 3 is placed behind the battery compartment wall and a plug connection terminal 3-1 is formed at the end. The base 8 is provided with a rod through hole for fastening the conductive rod 3. The specific rod through hole is composed of a small diameter hole 8-11 and a large diameter hole 8-12 connected up and down. A step surface 8-13 is formed at the diameter change. When the conductive rod 3 and the base 8 are installed, the rod segment 3-2 penetrates the small diameter hole 8-11 from one side of the large diameter hole 8-12 and is fastened to the base 8. The rod segment 3-2 partially extends upward from the small diameter hole 8-11. The rod seat 3-3 abuts against the step surface 8-13 as a limit and cooperates with the large diameter hole 8-12 with a gap. The gap can be used Figure 2 The arrow a in the middle indicates a glue-filled sealing treatment, and the outer end of the rod seat 3-3 forms the aforementioned plug electrical terminal 3-1; the side surface of the boss 6 and the side wall 5-2 of the sealing cap 5 of the outer sleeve are matched with each other in a concave and convex manner. In this embodiment, the boss is provided with an annular rib on the side surface and fits with the annular groove on the side wall of the sealing cap, so that the sealing cap is firmly mounted on the boss.
[0027] The socket 2 in this embodiment includes an insulating base 9 fixed to the bottom of the battery module and a conductive member 10 with a conductive socket 4. The base 9 forms a vertical tube with an open tubular cavity. The inner end of the vertical tube is hidden in the battery module, and the outer end is placed outside the battery module. The tubular cavity of the vertical tube includes a conductive member socket 11, a reduced diameter hole 12 and a step hole 7 that are connected from top to bottom. The diameter of the reduced diameter hole 12 is smaller than that of the conductive member socket 11 and the step hole 7. The conductive member 10 is inserted into the tubular cavity from the inner end of the vertical tube and is fastened to the vertical tube. The outer end of the conductive member 10 forms a socket power connection terminal 10-1. The step hole 7 is provided at the outer end of the vertical tube and is coaxially connected to the tubular cavity. The conductive member 10 is fastened to the vertical tube by inserting the conductive member socket 11. In order for the two to fit tightly, the conductive member socket 11 is a tapered hole with a larger inner portion and a smaller outer portion. When plugged in, the insertion section of the front of the conductive member 10 fits tightly with the tapered hole. The outer end of the rear of the conductive member 10 extends out of the tapered hole, and there is a gap between the conductive member 10 and the tapered hole. The gap can be used Figure 2 The arrow a' in the middle points to the glue-filling and sealing process.
[0028] The base 8 in this embodiment is fixed to the battery compartment wall and sealed with a first sealing ring 13. The base 8 is provided with an expanded diameter section to form a first mounting platform 8-2. The first mounting platform 8-2 is fixed to the battery compartment wall surface by bolts. The first sealing ring 13 is pressed between the first mounting platform 8-2 and the battery compartment wall. The base 9 is fixed to the bottom wall of the battery module shell and sealed with a second sealing ring 14. The base 9 is provided with an expanded diameter section to form a second mounting platform 9-1. The second mounting platform 9-1 is also provided with a reinforcing rib 9-2 connected to the vertical pipe section of the base 9 to reinforce the vertical pipe section. The second mounting platform 9-1 is fixed to the bottom wall surface of the shell by bolts. The second sealing ring 14 is pressed between the second mounting platform 9-1 and the bottom wall of the shell. Both the base and the base form corresponding mounting platforms through their respective expanded diameter sections and are fixed with four surrounding connecting bolts 15. The two sealing rings are pressed between the mounting platform and the corresponding wall surface to seal the installation opening opened on the wall surface. In addition, the plug and socket terminals are fixed with the same structure to lead out the power cord. Figure 2 Taking the middle plug electrical terminal as an example, it includes a clamping bolt 17 and a matching anti-loosening washer 16 and a clamping gasket 18. The clamping bolt passes through the anti-loosening washer and the clamping gasket in turn and is screwed into the pre-opened screw hole on the rod seat to fix it, so as to clamp the wire nose at one end of the power cord. In addition, other common structures can also be used to connect and fix the power cord.
