[0026] like Figure 1-6As shown, a waterproof structure of a battery for a water bicycle includes a shell 1 with openings at both ends and a battery assembly 2 arranged in the shell 1. Both ends of the shell 1 are respectively provided with a blocking cover 3 that is inserted into the opening to seal the battery assembly 2 in the shell 1, a sealing ring 4 that is sleeved on the open end of the shell 1 and whose inner side surface presses against the blocking cover 3, and an end cover that covers the sealing ring 4 to seal the opening of the shell 1 and presses against the sealing ring 4. One of the end covers is provided with a connector 6 for charging or discharging. The power cord of the battery assembly 2 passes through the blocking cover 3 and is electrically connected to the connector 6. A glue sealing layer is provided between the blocking cover 3 and the end cover. During assembly, the battery assembly 2 is installed into the square tube-shaped shell 1, and the blocking covers 3 are respectively installed in the openings at both ends of the shell 1, so that the battery assembly 2 is fixed in the shell 1 and the first sealing effect of the battery assembly 2 is achieved; then the sealing ring 4 is respectively set on the open ends on both sides of the shell 1, and the end cover is closed, and the sealing ring 4 is pressed against the blocking cover 3 by the end cover, so that the sealing ring 4 presses against the blocking cover 3, thereby improving the mutual sealing and achieving the second sealing effect; finally, a glue sealing layer is provided between the blocking cover 3 and the end cover to seal the gap between the end cover, the sealing ring 4 and the blocking cover 3, thereby achieving the third sealing effect, greatly improving the sealing of the water bicycle battery, and can also prevent water from entering when the water bicycle battery is immersed in water.
[0027] like Figure 1 As shown, the inner side surface of the shell 1 is provided with a plurality of ridges 11 arranged along the length direction and protruding inward, and the edge position of the blocking cover 3 is provided with a plurality of blocking cover recesses 31 respectively cooperating with the ridges 11, so that the blocking cover 3 is positioned and installed in the shell 1, while preventing the blocking cover 3 from rotating in the shell 1, and also better pressing the battery assembly 2 and locking the battery assembly 2 in the shell 1.
[0028] like Figure 1 As shown, a sealing ring pressing portion 41 is provided on the rear side surface of the sealing ring 4, which is arranged in a surrounding manner and extends backward to press the block cover 3. The outer side surface of the sealing ring pressing portion 41 is provided with a plurality of sealing ring pressing portion recesses 42 which respectively cooperate with the ridges 11, so that the sealing ring pressing portion 41 is positioned and installed in the shell body 1; a block cover positioning groove 32 is provided on the front side surface of the block cover 3 near the edge for the sealing ring pressing portion 41 to be installed, so that the sealing ring pressing portion 41 is positioned and installed and tightly presses against the block cover positioning groove 32, which can prevent the sealing ring pressing portion 41 from being deformed when pressed and generating gaps that affect the sealing performance, and can also transmit the pressure of the end cover pressing the sealing ring 4 to the block cover 3, thereby realizing a tight connection between each other.
[0029] like Figure 1 As shown, a plurality of sealing ring ribs 43 are provided on the outer side of the sealing ring pressing portion 41 to improve the sealing performance between the sealing ring pressing portion 41 and the inner side of the housing 1 .
[0030] like Figure 1As shown, an end cover pressing portion 51 is provided on the rear side surface of the end cover, which is arranged in a surrounding manner and extends backward to press against the sealing ring 4. An end cover positioning groove 44 is provided on the inner side surface of the sealing ring 4 for the end cover pressing portion 51 to be installed. After the end cover is closed, the end cover pressing portion 51 presses against the end cover positioning groove 44, so as to better transmit the pressing force of the end cover to the sealing ring 4, so that the sealing ring 4 presses against the blocking cover 3.
[0031] like Figure 1 As shown, threaded holes 12 are respectively provided on the side surfaces of both ends of the rib 11, a plurality of sealing ring through holes 45 are provided on the sealing ring 4 corresponding to the threaded holes 12, and a plurality of end cover through holes 52 are provided on the end cover through holes 52, the sealing ring through holes 45 and the threaded holes 12. By passing the screws through the end cover through holes 51, the sealing ring through holes 45 and the threaded holes 12, the end cover is pressed tightly against the sealing ring 4 and locked on the housing 1, thereby improving the sealing performance. At the same time, the threaded holes 12 are provided on the rib 11 and are independently separated from the inner cavity of the housing 1, and the sealing ring through holes 45 and the end cover through holes 52 are also provided at the edge of the end cover and are independently separated from the inner cavity of the end cover. After the end cover is closed, the screws do not need to pass through the inner cavity of the end cover, the inner side of the sealing ring 4 and the inner cavity of the housing 1, so that the inner cavity of the end cover and the inner cavity of the housing 1 form an independent closed cavity, thereby improving the overall sealing performance.
[0032] like Figure 1 As shown, the end cover is provided with two glue injection holes 53 for injecting glue. After the end cover is closed, silicone glue is injected into the gap between the end cover and the retaining cover 3 through one of the glue injection holes 53. During the injection of silicone glue, air is discharged from the other glue injection hole 53 to ensure that the gap between the end cover and the retaining cover 3 is filled with silicone glue to form a glue sealing layer. Finally, after the gap is filled with silicone glue, screws are installed in the glue injection hole 53 to close the glue injection hole 53.
[0033] like Figure 1 As shown, the two end covers are respectively a front end cover 54 and a rear end cover 55, a connector 6 is arranged on the front end cover 54 and the connector 6 is a magnetic waterproof connector, and a baffle 3 arranged on the rear side of the front end cover 54 is provided with a wire hole 33 for the power cord of the battery assembly 2 to pass through. After the power cord of the battery assembly 2 passes through the wire hole 33, silicone glue is applied on the wire hole 33 to seal the wire hole 33, and at the same time, the power cord is fixed on the wire hole 33 to prevent the wire from being pulled and broken.
[0034] like Figure 1As shown, the front cover 54 and rear cover 55 are each provided with a plurality of embedded nuts 7, and the connector 6 is secured to the embedded nuts 7 on the front cover 54 via screws. During the injection molding process of the front and rear covers 54, 55, the embedded nuts 7 are pre-embedded and integrally molded within the front and rear covers 54, 55. This prevents the rear sides of the embedded nuts 7 from communicating with the inner cavities of the front and rear covers 54, 55. The embedded nuts 7 on the rear cover 55 are used to securely connect to the water bike.
[0035] like Figure 1 As shown, the battery assembly 2 includes a battery bottom shell 21, in which a plurality of horizontally arranged and rechargeable batteries 22 are arranged. A plurality of conductive connecting pieces 23 are provided on both sides of the battery bottom shell 21, and a heat conducting plate 24 is provided on one side to cover the conductive connecting piece 23 and on the other side to contact the shell 1 to achieve heat conduction. A conductive connecting piece 23 is respectively connected to the positive terminal or negative terminal of the plurality of batteries 22. A battery circuit board 25 is provided on the upper side of the battery shell 1, which is respectively connected to the conductive connecting piece 23 and has a charge and discharge control circuit. The power line of the battery assembly 2 is connected to the charge and discharge control circuit. Figure 1 As shown, the conductive connecting ends of the conductive connecting piece 23 are respectively arranged to correspond to the conductive connecting ends of the battery circuit board 25. The conductive connecting ends of the conductive connecting piece 23 are shown in an unbent state. After being bent, the conductive connecting ends of the conductive connecting piece 23 are electrically connected to the conductive connecting ends of the battery circuit board 25. The battery circuit board 25 and the conductive connecting piece 23 connect the batteries 22 into a whole. During charging, the external adapter is connected to the connector 6, and the charge and discharge control circuit charges each battery 22. Similarly, during discharge, the power connector of the water bike is connected to the connector 6, and the charge and discharge control circuit supplies power to the water bike. The battery bottom shell 21 consists of a left battery bottom shell and a right battery bottom shell, which facilitates the installation of the batteries 22.
[0036] In this case, the shell 1, the battery bottom shell 21, and the heat conducting plate 24 are all aluminum components. During the charging and discharging process, the heat generated by the battery can be dissipated through the battery bottom shell 32, the heat conducting plate 24 and the shell 1.
[0037] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
