Waterproof venting pressure relief lock for battery compartment cover of water sports equipment

[0001] Cross-reference to Related Applications

[0002] This application claims priority to Chinese Patent Application No. 202411325939.5, filed on September 23, 2024 in China, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of water sports equipment, in particular to a waterproof venting pressure relief lock for battery compartment cover of water sports equipment. BACKGROUND

[0004] Water sports equipment such as powered surfboards, electric hydrofoil boards, etc. as a brand-new water sports product, mainly composed of surfboard body, battery / power system and operation system. It can slide on calm water, allowing people to fully enjoy the fun of surfing. Since this product is powered by batteries, the waterproof design of the battery is crucial to ensure the safety of the battery and the user. The design adopted by the prior art is mainly to design the waterproof level of the battery itself as IP68, and the battery compartment body where the battery is installed is designed as a sealed structure. The upper cover part of the battery compartment body is tightly combined with the compartment cover plate by means of a ring of sealing ring to realize sealing, and one side of the cover plate is fixed on the electric hydrofoil board body by a hinge, and the other side uses a waterproof and airtight rotary lock to control the opening and closing of the cover plate. In this way, the air tightness of the battery compartment body can be ensured, and the battery compartment body can be conveniently opened and closed, which is convenient for the taking and placing of the battery.

[0005] However, the battery will heat up during use. Due to the highly sealed air tight structure of this battery compartment, temperature difference will be generated when the battery heats up and the compartment cover is opened and closed, breaking the pressure balance inside and outside the battery compartment. This causes the pressure inside and outside the battery compartment cover to be unbalanced when the battery compartment cover is opened, and a negative pressure acts on the cover plate, making it very difficult to open the cover plate. A large pulling force is needed to offset the negative pressure on the cover plate before the cover plate can be opened.

[0006] After searching, there is no pressure relief structure or pressure difference balancing device provided on the battery compartment of existing powered surfboards, electric hydrofoil boards and other powered water sports equipment.

[0007] Therefore, there is an urgent need for a waterproof venting pressure relief lock for battery compartment cover of water sports equipment to overcome the above problems. SUMMARY

[0008] The present application provides a waterproof venting pressure relief lock for battery compartment cover of water sports equipment, which has both battery compartment cover locking function and venting pressure relief function.

[0009] The waterproof ventilation pressure relief lock buckle of the battery compartment cover plate of the water sports equipment provided by the application comprises a lock pull ring, a lock shaft, an elastic element, a lock tongue and a sealing pressure relief structure. The lock pull ring is pivotally connected to the top end of the lock shaft. The elastic element is sleeved on the outside of the lock shaft. The lock shaft comprises a movable lock shaft that can move up and down. The sealing pressure relief structure is arranged on the movable lock shaft. The sealing pressure relief structure can switch between the sealing state and the pressure relief state by moving up and down with the movable lock shaft, so as to block or connect the gas inside and outside the battery compartment cover plate, that is, when the sealing pressure relief structure is in the sealing state, the gas inside and outside the battery compartment cover plate is blocked, and a pressure difference can be formed between the inside and outside of the cover plate; when the sealing pressure relief structure is in the pressure relief state, the gas inside and outside the battery compartment cover plate is connected, and pressure relief can be performed to eliminate the pressure difference. The lock tongue is fixedly connected to the lower end of the lock shaft and can rotate with the lock shaft. When the lock pull ring is twisted, the lock shaft is rotated, so that the lock tongue changes the direction and the lock buckle is opened or closed.

[0010] Further, the waterproof ventilation pressure relief lock buckle further comprises an upper lock buckle shell and a lower lock buckle shell. The upper lock buckle shell and the lower lock buckle shell cooperate to fix the waterproof ventilation pressure relief lock buckle on the battery compartment cover plate.

[0011] Further, the end of the lock pull ring away from the pull ring is provided with an eccentric rotating shaft or an eccentric rotating shaft hole, and the top end of the lock shaft is provided with an eccentric rotating shaft hole or an eccentric rotating shaft matched with the eccentric rotating shaft or the eccentric rotating shaft hole of the lock pull ring, so that the lock pull ring and the top end of the lock shaft are pivotally connected in an eccentric manner.

[0012] Further, the end of the lock pull ring away from the pull ring is provided with an eccentric rotating shaft hole. The part of the lock pull ring provided with the eccentric rotating shaft hole is provided with a protrusion at the position that can contact the upper lock buckle shell, so that the thickness of the part of the lock pull ring is greater than the thickness of other parts of the pull ring, and the distance from the center line of the eccentric rotating shaft hole to the outermost edge of the protrusion (i.e. eccentric stroke L2) is greater than the distance from the center line of the eccentric rotating shaft hole to the bottom edge of the lock pull ring (i.e. eccentric stroke L1). When the lock pull ring is in the lowered closed state, the distance between the eccentric rotating shaft hole and the upper lock buckle shell is the eccentric stroke L2, and the movable lock shaft moves to the uppermost position. When the lock pull ring is in the open state, the distance between the eccentric rotating shaft hole and the upper lock buckle shell is the eccentric stroke L1, and the movable lock shaft moves to the lowermost position.

[0013] Further, the sealing pressure relief structure is composed of a lock shaft center hole, a lock shaft side hole and a sealing ring; the lock shaft center hole is located in the upper part of the mobile lock shaft and communicates with the outside atmosphere; the lock shaft side hole is located in the lower part of the mobile lock shaft and communicates with the lock shaft center hole; the sealing ring is sleeved on the outside of the lock shaft and located in the lock catch upper shell; the mobile lock shaft moves up and down to change the position of the lock shaft side hole; when the lock shaft side hole is located above the sealing ring, the sealing pressure relief structure is in a sealing state and the gas in and out of the battery compartment cover plate is blocked; when the lock shaft side hole is located below the sealing ring, the lock shaft side hole communicates with the battery compartment cover plate and the lock shaft center hole, and the sealing pressure relief structure is in a pressure relief state and the gas in and out of the battery compartment cover plate is communicated.

[0014] Further, the lock shaft side hole is a ventilation hole perpendicular to the lock shaft center hole and transversely arranged on the upper part of the mobile lock shaft.

[0015] Further, the lock shaft center hole of the sealing pressure relief structure is a blind hole located in the upper half of the lock shaft, and the hole opening is located at the top of the mobile lock shaft and communicates with the outside atmosphere.

[0016] Further, the elastic element is a spring, which is sleeved on the part of the lock shaft close to the lock tongue, between the lock tongue and the sealing ring.

[0017] In the normal use of the water sports equipment, the battery compartment cover plate is closed, the lock catch is locked, and the lock catch pull ring is in a flat state and located in the lock catch upper shell and flush with the battery compartment cover plate. At this time, the lock shaft side hole is located above the sealing ring, the gas in and out of the battery compartment cover plate is not communicated, and the sealing pressure relief structure is in a sealing state. When the battery compartment cover plate needs to be opened, the lock catch pull ring is pulled up to be parallel to the mobile lock shaft. Since the lock catch pull ring and the top end of the mobile lock shaft are eccentrically pivoted, after the pull ring is pulled up, the mobile lock shaft will move downward under the action of the spring, and at the same time, the lock shaft side hole moves to the lower part of the sealing ring and communicates with the inside of the battery compartment. Since the lock shaft center hole communicates with the lock shaft side hole, and the opening of the lock shaft center hole communicates with the outside of the battery compartment, the gas in and out of the battery compartment cover plate is communicated at this time, and the sealing pressure relief structure is in a pressure relief state. If there is a pressure difference, the pressure relief is realized, and the internal and external air pressures are balanced. In this state, the lock catch pull ring is continuously rotated to drive the lock shaft to rotate, the lock tongue rotates with it, the lock catch is unlocked, and the unlocking of the battery compartment cover plate is realized. After pressure relief and unlocking, the battery compartment cover plate can be easily opened.

[0018] Further, the sealing pressure relief structure can also be composed of a ventilation hole and a ventilation hole plug which cooperate with each other.

[0019] Further, the ventilation hole is a through hole arranged at the bottom of the lock catch upper shell.

[0020] Further, the ventilation hole plug is arranged on the outside of the lock shaft and can move up and down with the lock shaft, so as to cooperate with the ventilation hole at the bottom of the lock catch upper shell to open or close the ventilation hole.

[0021] When the lock catch is in the locked state, the vent hole plug is in the position of blocking the vent hole, at this time the battery compartment cover plate is not connected with the outside air, and the sealing pressure relief structure is in the sealed state. When the battery compartment cover plate needs to be opened, the lock catch pull ring is pulled up to be parallel to the moving lock shaft. Since the lock catch pull ring and the top end of the lock shaft are eccentric pivotally connected, after the pull ring is pulled up, the moving lock shaft will move downward under the action of the spring force, thereby moving the vent hole plug downward and away from the vent hole, so that the battery compartment cover plate is connected with the outside air, and the sealing pressure relief structure is in the pressure relief state. If there is a pressure difference, pressure relief is realized, and the internal and external air pressures are balanced. In this state, the lock catch pull ring is continuously rotated, thereby rotating the lock shaft and the lock tongue, unlocking the lock catch, and realizing the unlocking of the battery compartment cover plate. After pressure relief and unlocking, the battery compartment cover plate can be easily opened.

[0022] The waterproof venting pressure relief lock catch for the battery compartment cover plate of the water sports equipment provided in the application is eccentrically pivotally connected between the lock catch pull ring and the top end of the lock shaft. When the pull ring is pulled down or pulled up, the moving lock shaft is driven to move up and down, thereby driving the sealing pressure relief structure to switch between the sealed state and the pressure relief state. Therefore, the deflation and pressure relief can be realized before the lock catch of the battery compartment cover plate is opened, thereby preventing the problem that the cover plate cannot be opened due to the pressure difference between the inside and outside of the battery compartment. Meanwhile, the structure of the application is simple and can be repeatedly used, so that the cover of the battery compartment is more smooth, and the use experience is enhanced.

[0034] As shown in Figures 1, 2a, 2b, the waterproof venting and pressure relief lock catch 100 for the battery compartment cover plate 400 of the water sports equipment disclosed in the present application is installed on the battery compartment cover plate 400 of the water sports equipment. When locked, the lock catch shackle 1 is located in the lock catch upper shell 3, so that the overall waterproof venting and pressure relief lock catch is flush with or below the surface of the cover plate. The lock catch upper shell 3 cooperates with the lock catch lower shell 5 to fix the waterproof venting and pressure relief lock catch on the battery compartment cover plate 400. The battery compartment body 300 is used in cooperation with the battery compartment cover plate 400, and when the cover plate is closed, the battery can be sealed in the compartment. The battery compartment body 300 is provided with a lock catch base 200, and the lock tongue 8 of the waterproof venting and pressure relief lock catch can cooperate with the lock catch base 200 to lock the cover plate and ensure sealing.

[0035] Please refer to Fig. 3a and Fig. 3b, the waterproof and air-ventilating pressure relief lock buckle for the battery compartment cover plate of the water sports equipment provided by the present application comprises a lock pull ring 1, a lock shaft 10, an elastic element, a lock tongue 8 and a sealing pressure relief structure. The lock shaft comprises a movable lock shaft which can move up and down, and the sealing pressure relief structure is arranged on the movable lock shaft. The sealing pressure relief structure can switch between the sealing and pressure relief states with the up and down movement of the movable lock shaft, so as to block or connect the gas inside and outside the battery compartment cover plate. That is, when the sealing pressure relief structure is in the sealing state, the gas inside and outside the battery compartment cover plate is blocked, and a pressure difference can be formed between the inside and outside of the cover plate. When the sealing pressure relief structure is in the pressure relief state, the gas inside and outside the battery compartment cover plate is connected, and the pressure can be relieved to eliminate the pressure difference. The lock tongue 8 is fixedly connected to the lower end of the lock shaft 10 and can rotate with the movable lock shaft. When the lock pull ring 1 is twisted, the lock shaft 10 will be rotated, so that the lock tongue 8 changes the direction and the lock buckle can be opened or locked.

[0036] Please refer to Fig. 5, the lock pull ring 1 is provided with an eccentric pivot hole 14 at the end away from the pull ring, the top end of the lock shaft 10 is provided with an eccentric pivot 17 matched with the eccentric pivot hole 14 of the lock pull ring 1, and the part of the lock pull ring 1 provided with the eccentric pivot hole is integrally provided with a protrusion at the position in contact with the lock buckle upper cover 3, so that the thickness of this part of the lock pull ring is greater than that of the part of the lock pull ring, thereby forming the eccentric pivot connection between the lock pull ring 1 and the top end of the lock shaft 10.

[0037] Please refer to Fig. 4, due to the protrusion integrally arranged at the bottom of the lock pull ring 1, the thickness of this part is greater than that of the pull ring itself, forming an eccentric structure. The pull ring has two eccentric strokes L1 and L2. The eccentric stroke L1 is the distance from the center line of the eccentric pivot hole 14 to the bottom edge of the pull ring, and the eccentric stroke L2 is the distance from the center line of the eccentric pivot hole 14 to the outermost edge of the protrusion. This makes the position of the center line of the eccentric pivot hole vertically move a distance of L2-L1 during the process of the pull ring changing from the pulled-up state to the put-down state, and vice versa, so that pulling the lock pull ring can drive the movable lock shaft to move up and down.

[0038] The waterproof and air-ventilating pressure relief lock buckle is also provided with a sealing gasket 15 at the edge of the lock buckle upper shell, which is used to ensure the sealing between the lock buckle and the cover plate.

[0039] The lock buckle upper shell is also provided with a pull ring stop ring 16, which is sleeved on the outside of the lock shaft. One end of the pull ring can be in contact with the pull ring stop ring, so as to ensure the sealing between the pull ring, the lock shaft and the lock buckle upper shell.

[0040] As shown in FIG. 3a and FIG. 3b, the waterproof ventilation pressure relief lock of the battery compartment cover plate for water sports equipment in the present application is the first embodiment: the sealing pressure relief structure is composed of the lock shaft center hole 11, the lock shaft side hole 7 and the sealing ring 6. The lock shaft center hole 11 is located in the upper part of the movable lock shaft and communicates with the outside atmosphere; the lock shaft side hole 7 is located in the lower part of the movable lock shaft and communicates with the lock shaft center hole 11; the sealing ring 6 is sleeved on the outside of the lock shaft 10 and located in the upper shell 3 of the lock; the movable lock shaft moves up and down to change the position of the lock shaft side hole 7, when the lock shaft side hole 7 is above the sealing ring 6, the sealing pressure relief structure is in a sealing state, and the gas in and out of the battery compartment cover plate is blocked; when the lock shaft side hole 7 is below the sealing ring 6, the lock shaft side hole communicates with the inside of the battery compartment cover plate and the lock shaft center hole, and the sealing pressure relief structure is in a pressure relief state, and the gas in and out of the battery compartment cover plate is communicated.

[0041] Further, the lock shaft side hole 7 is a ventilation hole perpendicular to and communicating with the lock shaft center hole 11, which is transversely arranged on the upper part of the movable lock shaft.

[0042] Further, the lock shaft center hole 11 of the sealing pressure relief structure is a blind hole located in the upper half of the lock shaft, and the hole opening is located at the top of the movable lock shaft and communicates with the outside atmosphere.

[0043] Further, the elastic element is a spring 9, which is sleeved on the part of the lock shaft close to the lock tongue 8 and located between the lock tongue and the sealing ring.

[0044] In the normal use of the water sports equipment, the battery compartment cover plate is closed, the lock is locked, and the lock pull ring 1 is in a flat state and located in the upper shell 3 of the lock and flush with the battery compartment cover plate. At this time, the lock shaft side hole 7 is located above the sealing ring 6, the gas in and out of the cover plate is not communicated, and the sealing pressure relief structure is in a sealing state. When the battery compartment cover plate needs to be opened, the lock pull ring 1 is pulled up to be parallel to the lock shaft 10. Since the lock pull ring 1 is eccentrically connected to the top end of the lock shaft 10, after the pull ring is pulled up, the movable lock shaft moves downward under the action of the spring 9, at the same time, the lock shaft side hole 7 moves to the lower part of the sealing ring, and the lock shaft side hole 7 communicates with the inside of the battery compartment at this time. Since the lock shaft center hole 11 communicates with the lock shaft side hole 7, and the top opening of the lock shaft center hole 11 communicates with the atmosphere, the gas in and out of the battery compartment cover plate is communicated at this time, and the sealing pressure relief structure is in a pressure relief state. If there is a pressure difference, the pressure relief is realized, and the internal and external air pressures are balanced. In this state, the lock pull ring 1 is continued to be rotated, which drives the lock shaft 10 to rotate, the lock tongue 8 rotates, the lock is unlocked, and the unlocking of the battery compartment cover plate 400 is realized. After pressure relief and unlocking, the battery compartment cover plate can be easily opened.

[0045] In combination with FIG. 6a and FIG. 6b, the waterproof ventilation pressure relief lock of the battery compartment cover plate for water sports equipment in the present application is the second embodiment: the sealing pressure relief structure is also composed of the ventilation hole and the ventilation hole plug which cooperate with each other.

[0046] Further, the air hole 12 is a through hole arranged at the bottom of the upper shell 3 of the lock.

[0047] Further, the air hole plug 13 is arranged outside the lock shaft 10 and can move up and down with the lock shaft 10, so as to cooperate with the air hole 12 at the bottom of the upper shell 3 of the lock, so that the air hole 12 is opened or closed.

[0048] When the lock is in the locked state, the air hole plug 13 is located at the position of plugging the air hole 12, at this time, the inside and outside air of the battery compartment cover plate is not communicated, and the sealing pressure relief structure is in the sealed state. When it is needed to open the battery compartment cover plate, the lock pull ring 1 is pulled up to be parallel to the lock shaft 10, because the lock pull ring 1 and the top end of the moving lock shaft are eccentrically connected, after the pull ring is pulled up, the moving lock shaft will move downward under the action of the spring 9, so as to drive the air hole plug 13 to move downward, away from the air hole 12, so that the inside and outside air of the battery compartment cover plate is communicated, and the sealing pressure relief structure is in the pressure relief state, if there is a pressure difference, the pressure relief is realized, and the inside and outside air pressure is balanced. In this state, the lock pull ring 1 is continuously rotated, so as to drive the lock shaft 10 to rotate, the lock tongue 8 rotates, the lock is unlocked, and the unlocking of the battery compartment cover plate is realized. After the pressure relief and unlocking, the battery compartment cover plate can be easily opened, and the problem of air pressure negative pressure adsorption does not occur, and the use experience is improved.

[0049] The waterproof air venting and pressure relief lock for the battery compartment cover plate of the water sports equipment provided in the application is eccentrically pivotally connected between the lock pull ring 1 and the top end of the lock shaft 10, so that when the pull ring is laid flat or pulled up, the lock shaft 10 is driven to move up and down, so as to drive the sealing pressure relief structure to switch between the sealing and pressure relief states, so that the air relief is realized before the lock of the battery compartment cover plate is opened, and the problem that the cover plate cannot be opened due to the pressure difference between the inside and outside of the battery compartment is prevented. Meanwhile, the structure of the application is simple and can be repeatedly used, so that the opening of the battery compartment cover is more smooth, and the use experience is enhanced.
