Abstract
Description
Technical Field
[0001] The present application relates to the field of water sports equipment, and in particular to a waterproof ventilation and pressure relief lock buckle for a battery compartment cover of water sports equipment. Background Art
[0002] As a new type of water sports product, water sports equipment such as powered surfboards and electric hydrofoil boards are mainly composed of a surfboard body, a battery / power system, and an operating system. It can glide on calm water, allowing people to fully experience the fun of surfing. Given that the 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 in the prior art is mainly to design the waterproof level of the battery itself to IP68, and the battery compartment body for installing and storing the battery is designed as a sealed structure. The upper cover of the battery compartment body is tightly combined with the compartment cover plate by a circle of sealing rings to achieve sealing. One side of the cover plate is fixed to the electric hydrofoil board body by hinges, and the other side uses a waterproof and airtight rotating lock to control the opening and closing of the cover plate. In this way, the airtight performance of the battery compartment body can be guaranteed, and the convenient opening and closing of the battery compartment body can be achieved, which is convenient for taking and placing the battery.
[0003] However, the battery will heat up during use. Due to the highly sealed airtight structure of the battery compartment, a temperature difference will occur when the battery heats up and when 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 there is a negative pressure on the cover, making it extremely difficult to open the cover. A sufficiently large pulling force is required to offset the negative pressure on the cover before the cover can be opened.
[0004] After searching, it was found that existing powered water sports equipment such as powered surfboards and electric hydrofoil boards do not have a pressure relief structure or pressure difference balancing device set on the battery compartment.
[0005] Based on this, there is an urgent need for a waterproof ventilation and pressure relief lock buckle for a battery compartment cover of water sports equipment to overcome the above problems. Summary of the invention
[0006] The present application provides a waterproof ventilation and pressure relief lock buckle for a battery compartment cover of water sports equipment, which has both a battery compartment cover locking function and a ventilation and pressure relief function.
[0007] The waterproof ventilating pressure relief lock for the battery compartment cover of water sports equipment provided by the present 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 of the lock shaft; the elastic element is sleeved outside the lock shaft. The lock shaft comprises a movable lock shaft that can move up and down, and a sealing pressure relief structure is arranged on the movable lock shaft. The sealing pressure relief structure can switch the sealing and pressure relief states with the up and down movement of the movable lock shaft, so that the gas inside and outside the battery compartment cover is blocked or connected, that is, when the sealing pressure relief structure is in a sealing state, the gas inside and outside the battery compartment cover is blocked, and a pressure difference may be formed inside and outside the cover; and when the sealing pressure relief structure is in a pressure relief state, the gas inside and outside the battery compartment cover 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 will be driven to rotate, so that the lock tongue changes direction, and the lock can be opened or closed.
[0008] Furthermore, the waterproof ventilation and pressure relief lock buckle also includes a lock buckle upper shell and a lock buckle lower shell, and the lock buckle upper shell cooperates with the lock buckle lower shell to fix the waterproof ventilation and pressure relief lock buckle on the battery compartment cover.
[0009] Furthermore, an eccentric shaft or an eccentric shaft hole is provided at one end of the lock pull ring away from the pull ring, and an eccentric shaft hole or an eccentric shaft is provided at the top end of the lock shaft to cooperate with the eccentric shaft or the eccentric shaft hole of the lock pull ring, thereby forming an eccentric pivot connection between the lock pull ring and the top end of the lock shaft.
[0010] Furthermore, an eccentric shaft hole is provided at one end of the lock pull ring away from the pull ring, and a protrusion is extended from the part of the lock pull ring with the eccentric shaft hole at a position where it can contact the lock upper shell, so that the thickness of this part of the lock pull ring is greater than the thickness of other parts of the pull ring, and thus the distance from the center line of the eccentric shaft hole to the outermost edge of the protrusion (i.e., the eccentric stroke L2) is greater than the distance from the center line of the eccentric shaft hole to the bottom edge of the lock pull ring (i.e., the eccentric stroke L1); when the lock pull ring is in a lowered and closed state, the distance between the eccentric shaft hole and the lock upper shell is the eccentric stroke L2, and the mobile lock shaft moves up to the uppermost position; when the lock pull ring is in an open state, the distance between the eccentric shaft hole and the lock upper shell is the eccentric stroke L1 distance, and the mobile lock shaft moves down to the lowermost position.
[0011] Furthermore, 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 inner part of the movable lock shaft and communicates with the external atmosphere; the lock shaft side hole is located in the lower part of the movable lock shaft and communicates with the lock shaft center hole; the sealing ring is sleeved outside the lock shaft and located in the lock buckle upper shell; the movable lock shaft moves up and down to drive the position of the lock shaft side hole to change, when the lock shaft side hole is located above the sealing ring, the sealing pressure relief structure is in a sealed state, and the gas inside and outside the battery compartment cover is blocked; when the lock shaft side hole is located below the sealing ring, the lock shaft side hole connects the battery compartment cover and the lock shaft center hole, the sealing pressure relief structure is in a pressure relief state, and the gas inside and outside the battery compartment cover is connected.
[0012] Furthermore, the side hole of the lock shaft is a vent hole that is perpendicular to and connected to the central hole of the lock shaft, and is transversely penetrated and arranged on the upper part of the movable lock shaft.
[0013] Furthermore, the central hole of the lock shaft of the sealing and pressure relief structure is a blind hole located in the upper part of the lock shaft, and its opening is located at the top of the movable lock shaft and is connected to the external atmosphere.
[0014] Furthermore, the elastic element is a spring, and the spring is sleeved on the outside of the lock shaft near the lock tongue and is located between the lock tongue and the sealing ring.
[0015] During normal use of the water sports equipment, the battery compartment cover is closed, the lock is locked, and the lock ring is in a flat state, located inside the lock upper shell, flush with the battery compartment cover. At this time, the lock shaft side hole is located on the upper part of the sealing ring, the gas inside and outside the cover is not connected, and the sealing pressure relief structure is in a sealed state. When the battery compartment cover needs to be opened, the lock ring is pulled up to be parallel to the movable lock shaft. Since the lock ring and the top of the movable lock shaft are eccentrically pivoted, after the pull ring is pulled up, the movable lock shaft will move downward under the action of the spring. At the same time, the lock shaft side hole moves to the lower part of the sealing ring and is connected to the inside of the battery compartment; since the lock shaft center hole is connected to the lock shaft side hole, and the opening of the lock shaft center hole is connected to the outside of the battery compartment, the gas above and below the battery compartment cover is connected, and the sealing pressure relief structure is in a pressure relief state. If there is a pressure difference, pressure relief is achieved to balance the internal and external air pressures. In this state, continue to rotate the lock ring to drive the lock shaft to rotate, and the lock tongue rotates accordingly, and the lock is unlocked to unlock the battery compartment cover. After releasing the pressure and unlocking, the battery compartment cover can be easily opened.
[0016] Furthermore, the sealing pressure relief structure may also be composed of vent holes and vent hole plugs that cooperate with each other.
[0017] Furthermore, the vent hole is a through hole arranged at the bottom of the lock upper shell.
[0018] Furthermore, the vent plug is arranged on the outside of the lock shaft and can move up and down with the lock shaft, thereby cooperating with the vent at the bottom of the lock upper shell to open or close the vent.
[0019] When the lock is in the locked state, the vent plug is located in the position blocking the vent. At this time, the gas inside and outside the battery compartment cover is not connected, and the sealed pressure relief structure is in a sealed state. When the battery compartment cover needs to be opened, pull up the lock pull ring until it is parallel to the movable lock shaft. Since the lock pull ring and the top of the lock shaft are eccentrically pivoted, after pulling up the pull ring, the movable lock shaft will move downward under the action of the spring, thereby driving the vent plug to move downward and leave the vent, so that the gas inside and outside the battery compartment cover is connected, and the sealed pressure relief structure is in a pressure relief state. If there is a pressure difference, pressure relief is achieved to balance the internal and external air pressures. In this state, continue to rotate the lock pull ring to drive the lock shaft to rotate, and the lock tongue will rotate accordingly, and the lock will be unlocked to unlock the battery compartment cover. After pressure relief and unlocking, the battery compartment cover can be easily opened.
[0020] The waterproof ventilated pressure relief lock buckle for the battery compartment cover of water sports equipment provided by the present application is eccentrically pivotally connected to the top of the lock shaft through the lock buckle pull ring, and can drive the movable lock shaft to move up and down when the pull ring is laid flat or pulled up, thereby driving the sealed pressure relief structure to switch between the sealed and pressure relief states. Therefore, before opening the battery compartment cover buckle, air can be deflated and pressure can be relieved, preventing the problem of the cover being unable to be opened due to the pressure difference inside and outside the battery compartment. At the same time, the present application has a simple structure and can be used repeatedly, making the battery compartment cover opening smoother and enhancing the user experience.

Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.
[0032] like Figure 1 , Figure 2a , Figure 2b As shown, the waterproof venting and pressure relief lock buckle 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 in the locked state, the lock buckle pull ring 1 is located in the lock buckle upper shell 3, so that the waterproof venting and pressure relief lock buckle as a whole is kept flush with the surface of the cover plate or lower than the surface of the cover plate. The lock buckle upper shell 3 cooperates with the lock buckle lower shell 5 to fix the waterproof venting and pressure relief lock buckle on the battery compartment cover plate 400. The battery compartment body 300 is used in conjunction with the battery compartment cover plate 400, and the battery can be sealed in the compartment when the cover plate is closed. A lock buckle base 200 is provided on the edge of the battery compartment body 300, and the lock tongue 8 of the waterproof venting and pressure relief lock buckle can cooperate with the lock buckle base 200 to lock the cover plate and ensure sealing.
[0033] Please also see Figure 3a , Figure 3bThe waterproof ventilating pressure relief lock for the battery compartment cover of water sports equipment provided in the present application comprises: a lock pull ring 1, a lock shaft 10, an elastic element 9, a lock tongue 8, and a sealing pressure relief structure. The lock shaft comprises a movable lock shaft that can move up and down, and a sealing pressure relief structure is arranged on the movable lock shaft. The sealing pressure relief structure can switch the sealing and pressure relief states with the up and down movement of the movable lock shaft, so that the gas inside and outside the battery compartment cover is blocked or connected, that is, when the sealing pressure relief structure is in a sealing state, the gas inside and outside the battery compartment cover is blocked, and a pressure difference may be formed inside and outside the cover; and when the sealing pressure relief structure is in a pressure relief state, the gas inside and outside the battery compartment cover is connected, and pressure relief can be performed 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 driven to rotate, so that the lock tongue 8 changes its direction, and the lock can be opened or locked.
[0034] See also Figure 5 An eccentric shaft hole 14 is provided at the end of the lock pull ring 1 away from the pull ring, and an eccentric shaft 17 matching the eccentric shaft hole 14 of the lock pull ring 1 is provided at the top of the lock shaft 10. The portion of the lock pull ring 1 provided with the eccentric shaft hole is integrally provided with a protrusion at a position in contact with the lock upper cover 3, so that the thickness of this portion of the lock pull ring is greater than the thickness of the lock pull ring portion, thereby forming an eccentric pivot connection between the lock pull ring 1 and the top of the lock shaft 10.
[0035] See also Figure 4 Due to the protrusion integrally provided at the bottom of the lock pull ring 1, the thickness of this part is greater than the thickness 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 shaft 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 shaft hole 14 to the outermost edge of the protrusion. This makes the position of the center line of the eccentric shaft hole move vertically upward by a distance of L2-L1 when the pull ring changes from the pulled state to the lowered state, and vice versa, so that pulling the lock pull ring can drive the movable lock shaft to move up and down.
[0036] The waterproof, ventilated and pressure-relief lock buckle is also provided with a sealing gasket 15 located at the edge of the lock buckle upper shell, which is used to ensure the seal between the lock buckle and the cover plate.
[0037] A pull ring retaining ring 16 is also provided in the lock buckle upper shell and sleeved outside the lock shaft. One end of the pull ring can contact the pull ring retaining ring to ensure the seal between the pull ring, the lock shaft and the lock buckle upper shell.
[0038] like Figure 3a and 3b, Embodiment 1 of the waterproof ventilated pressure relief lock buckle for the battery compartment cover of water sports equipment in the present application is: the sealing pressure relief structure can be composed of a lock shaft center hole 11, a lock shaft side hole 7, and a sealing ring 6. The lock shaft center hole 11 is located in the upper part of the movable lock shaft and communicates with the external 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 outside the lock shaft 10 and is located in the lock buckle upper shell 3; the movable lock shaft moves up and down to drive the position of the lock shaft side hole 7 to change. When the lock shaft side hole 7 is located above the sealing ring 6, the sealing pressure relief structure is in a sealing state, and the gas inside and outside the battery compartment cover is blocked; when the lock shaft side hole 7 is located below the sealing ring 6, the lock shaft side hole communicates with the battery compartment cover and the lock shaft center hole, the sealing pressure relief structure is in a pressure relief state, and the gas inside and outside the battery compartment cover is communicated.
[0039] Furthermore, the lock shaft side hole 7 is a vent hole that is perpendicular to and connected to the lock shaft center hole 11 and is transversely penetrated and arranged on the upper part of the movable lock shaft.
[0040] Furthermore, 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 its opening is located at the top of the movable lock shaft and communicates with the external atmosphere.
[0041] Furthermore, the elastic element is a spring 9, which is sleeved on the outside of the lock shaft near the lock tongue 8 and is located between the lock tongue and the sealing ring.
[0042] During normal use of the water sports equipment, the battery compartment cover is closed, the lock is locked, and the lock pull ring 1 is in a flat state, located inside the lock upper shell 3, flush with the battery compartment cover. At this time, the lock shaft side hole 7 is located on the upper part of the sealing ring 6, the gas inside and outside the cover is not connected, and the sealing pressure relief structure is in a sealed state. When the battery compartment cover 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 of the lock shaft 10, after the pull ring is pulled up, the movable lock shaft will move 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 is now connected to the inside of the battery compartment; since the lock shaft center hole 11 is connected to the lock shaft side hole 7, and the top opening of the lock shaft center hole 11 is connected to the atmosphere, the gas above and below the battery compartment cover is connected at this time, and the sealing pressure relief structure is in a pressure relief state. If there is a pressure difference, pressure relief is achieved to balance the internal and external air pressures. In this state, the lock pull ring 1 is continuously rotated to drive the lock shaft 10 to rotate, and the lock tongue 8 rotates accordingly, and the lock is unlocked to unlock the battery compartment cover 400. After the pressure is released and unlocked, the battery compartment cover can be easily opened.
[0043] Combination Figure 6a and Figure 6b , Embodiment 2 of the waterproof ventilation and pressure relief lock buckle for the battery compartment cover of water sports equipment in the present application is: the sealing and pressure relief structure can also be composed of mutually cooperating vents and vent plugs.
[0044] Furthermore, the vent hole 12 is a through hole arranged at the bottom of the lock upper shell 3.
[0045] Furthermore, the vent plug 13 is disposed on the outside of the lock shaft 10 and can move up and down with the lock shaft 10, thereby cooperating with the vent 12 at the bottom of the lock upper shell 3 to open or close the vent 12.
[0046] When the lock is in the locked state, the vent plug 13 is located at the position blocking the vent 12. At this time, the gas inside and outside the battery compartment cover is not connected, and the sealed pressure relief structure is in a sealed state. When the battery compartment cover needs to be opened, pull up the lock pull ring 1 to be parallel to the lock shaft 10. Since the lock pull ring 1 is eccentrically connected to the top of the movable lock shaft, after the pull ring is pulled up, the movable lock shaft will move downward under the action of the spring 9, thereby driving the vent plug 13 to move downward and leave the vent 12, so that the gas inside and outside the battery compartment cover is connected, and the sealed pressure relief structure is in a pressure relief state. If there is a pressure difference, pressure relief is achieved to balance the internal and external air pressures. In this state, continue to rotate the lock pull ring 1 to drive the lock shaft 10 to rotate, and the lock tongue 8 will rotate accordingly, and the lock will be unlocked to unlock the battery compartment cover. After the pressure is relieved and unlocked, the battery compartment cover can be easily opened without the problem of negative pressure adsorption, which improves the user experience.
[0047] The waterproof ventilated pressure relief lock buckle for the battery compartment cover of water sports equipment provided by the present application is eccentrically pivotally connected to the top of the lock shaft 10 through the lock buckle pull ring 1, and can drive the lock shaft 10 to move up and down when the pull ring is laid flat or pulled up, thereby driving the sealed pressure relief structure to switch between the sealed and pressure relief states, so that the deflation and pressure relief can be achieved before opening the battery compartment cover buckle, preventing the problem of the cover being unable to be opened due to the pressure difference inside and outside the battery compartment. At the same time, the present application has a simple structure and can be used repeatedly, making the battery compartment cover opening smoother and enhancing the user experience.
