[0034] In order to make the technical problems, technical solutions and beneficial effects of the embodiments of the present application clearer, the following will further describe the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0035] The principles and structures of the present application will be described in detail below with reference to the accompanying drawings and embodiments.
[0036] Although the existing automatic lock structure improves the convenience of the lock to some extent, it is prone to misoperation or environmental interference (such as water pressure, temperature change, etc.) due to its dependence on mechanical linkage or electronic control, which may cause misoperation or oversensitivity, further increasing the possibility of accidental opening of the hatch. These problems not only affect the waterproof performance of the product, but also may cause the user to face the risk of data loss or equipment damage due to misoperation during use.
[0037] To this end, as shown in the utility model discloses a waterproof cabin door structure, comprising: shell material 1 and cabin door. Figure 1 The shell material 1 is provided with a mounting groove 11, and the mounting groove 11 is used for arranging an electronic interface such as a charging interface or a data interface of a camera.
[0038] Specifically, the cabin door is internally provided with a sandwich layer, which is located in the internal space of the cabin door and is used for mounting and accommodating functional components. The outer side of the cabin door is provided with a push-pull knob 22 and an anti-misoperation knob 23. The push-pull knob 22 is used for actuating a push-pull switch 3 inside the cabin door, and the anti-misoperation knob 23 is used for actuating an anti-misoperation switch 4 inside the cabin door. The sandwich layer is internally provided with the push-pull switch 3 and the anti-misoperation switch 4. The push-pull switch 3 is used for controlling the locking state of the cabin door, and the anti-misoperation switch 4 is used for preventing the cabin door from being accidentally opened due to misoperation. When the cabin door is rotated to a position covering and sealing the mounting groove 11, a push-pull actuating block 30 is actuated to an open position, and the end of the push-pull switch 3 is inserted into a socket on the inner wall of the shell material 1 in the mounting groove 11, so that the cabin door is locked. When the anti-misoperation switch 4 is actuated to the open position, push-pull actuation can be limited, and the cabin door can be prevented from being accidentally opened due to misoperation.
[0039] By arranging the push-pull switch 3 and the anti-misoperation switch 4 in the sandwich layer of the cabin door, the locking and anti-misoperation functions of the cabin door are realized. When the anti-misoperation switch 4 is actuated to the open position, push-pull actuation can be limited, and the cabin door can be prevented from being accidentally opened due to misoperation, so that water can be effectively prevented from penetrating into the camera through the mounting groove 11. The structure realizes double locking and anti-misoperation design, ensures the reliable sealing performance and stability of the cabin door in the closed position, avoids accidental opening caused by misoperation, and improves the waterproof performance and use safety of the camera.
[0040] In a specific embodiment, the hatch includes a hatch cover 2 and a sealing inner cover 5. A sandwich layer for installing the switch is formed between the hatch cover 2 and the sealing inner cover 5. The hatch cover 2 is connected to the shell material 1 by a pin 21 and can rotate on the shell material 1 to switch between the open and closed positions. The sealing inner cover 5 is installed on the inner side of the hatch cover 2 and tightly fits the hatch cover 2 to form a reliable sealing structure. The sandwich layer between the hatch cover 2 and the sealing inner cover 5 is used to install the push-pull switch 3 and the anti-misoperation switch 4. The outer side of the hatch cover 2 is provided with a push-pull slot 22 and an anti-misoperation slot 23, which are actually groove spaces through which the user can directly manipulate the push-pull switch 3 and the anti-misoperation switch 4 in the inner sandwich layer. The push-pull switch 3 and the anti-misoperation switch 4 are installed in the sandwich layer, the end of the push-pull switch 3 is located inside the sandwich layer when not manipulated, extends out of the sandwich layer when manipulated to the open position, and is inserted into the corresponding socket on the shell material 1 to lock the hatch; when manipulated to the closed position, the end of the push-pull switch 3 is withdrawn from the socket of the shell material 1 and is retracted into the sandwich layer to release the locking state of the hatch. The end of the anti-misoperation switch 4 is also located inside the sandwich layer, and when manipulated to the open position, the anti-misoperation switch 4 restricts the operation of the push-pull slot 22 to prevent accidental opening of the hatch due to misoperation. When the hatch is rotated to cover and seal the installation groove 11 on the shell material 1, the user can manipulate the push-pull switch 3 through the push-pull slot 22 to make the end of the push-pull switch 3 inserted into the socket on the shell material 1 to complete the locking of the hatch, and the sealing inner cover 5 tightly fits the installation groove 11 on the shell material 1 to achieve a reliable sealing effect. At the same time, the anti-misoperation switch 4 can be manipulated through the anti-misoperation slot 23 to restrict the operation of the push-pull slot 22, avoiding accidental opening of the hatch due to misoperation. This structure forms a reliable sealing structure through the cooperation of the hatch cover 2 and the sealing inner cover 5, and realizes the locking and anti-misoperation functions of the hatch through the push-pull switch 3 and the anti-misoperation switch 4 installed in the sandwich layer.
[0041] In a further embodiment, the sealing inner cover 5 includes a first pressing sheet 7 wrapping a silica gel piece 6, and a second pressing sheet 8 connected to the first pressing sheet 7, the second pressing sheet 8 and the hatch cover 2 form a sandwich layer for installing the push-pull switch 3 and the anti-misoperation switch 4. The first pressing sheet 7 wrapping the silica gel piece 6 can improve the strength of the silica gel piece to improve the sealing effect. The four side surfaces of the silica gel piece 6 are provided with layered sealing rings, which can provide multiple layers of sealing effect to further enhance the sealing performance between the hatch and the shell material 1. The softness and elasticity of the silica gel piece 6 enable it to tightly fit the installation groove 11 on the shell material 1 when the hatch is closed, effectively preventing moisture from penetrating. The design of the layered sealing rings not only improves the reliability of the sealing, but also maintains good sealing state in long-term use, avoiding sealing failure due to aging or deformation.
[0042] Preferably, corresponding positions on the first pressing piece 7 and the second pressing piece 8 of the sealing inner cover 5 are provided with screw holes, and the first pressing piece 7, the second pressing piece 8 and the hatch upper cover can be connected by screws. In addition, the pressing piece can also be connected to the hatch in other mounting forms, such as buckling, bonding and the like.
[0043] Preferably, the first pressing piece 7 and the second pressing piece 8 are both hardware.
[0044] In a specific embodiment, the middle part of the push-pull switch 3 is designed with a square notch 31 which penetrates the main part of the push-pull switch 3, facilitating the cooperation of the anti-misoperation switch 4. The inner edge of the square notch 31 is provided with an anti-misoperation notch 32 for position cooperation with the anti-misoperation protrusion 41 of the anti-misoperation switch 4. The anti-misoperation switch 4 is located in the area of the square notch 31, and the edge thereof is designed with an anti-misoperation protrusion 41. When the push-pull switch 3 is turned to the open position, the anti-misoperation protrusion 41 of the anti-misoperation switch 4 is opposite to the anti-misoperation notch 32. At this time, the anti-misoperation switch 4 has not been triggered, and the end of the push-pull switch 3 extends from the interlayer and is inserted into the socket on the shell 1, completing the locking of the hatch. When the anti-misoperation switch 4 is turned to the open position, the anti-misoperation protrusion 41 is inserted into the anti-misoperation notch 32, forming a mechanical limit. The turning of the push-pull switch 3 can be effectively limited, preventing accidental opening of the hatch due to misoperation. Through the cooperation of the square notch 31, the anti-misoperation notch 32 and the anti-misoperation protrusion 41, a reliable mechanical limiting relationship is formed between the push-pull switch 3 and the anti-misoperation switch 4.
[0045] In a preferred embodiment, the turning direction of the push-pull switch 3 is perpendicular to the turning direction of the anti-misoperation switch 4. The specific turning direction of the push-pull switch 3 is left-right turning in the figure, and the turning direction of the anti-misoperation switch 4 is up-down turning in the figure, making the structure simple and the user more easily distinguishing the operation of the two switches.
[0046] In a preferred embodiment, the surfaces of the push-pull switch 3 and the anti-misoperation switch 4 are designed with a plurality of contact protrusions which are uniformly distributed on the surfaces, and specifically can be semicircular protrusions. This makes the turning of the switch more smooth, reduces the sliding resistance and improves the operation experience of the user. At the same time, this design also enhances the reliability and durability of the switch and prolongs the service life.
[0047] In the preferred embodiment, the edges of the push-pull switch 3 and the anti-misoperation switch 4 are provided with a plurality of concave points on both sides parallel to the direction of their actuation, forming a limiting reference. Two auxiliary limiting elastic sheets 9 are fixed in the interlayer and correspond to the push-pull switch 3 and the anti-misoperation switch 4 respectively. The protruding part of the auxiliary limiting elastic sheet 9 is designed to match the shape of the concave point, which can be accurately clamped into the concave point, thereby realizing the limiting and fixing of the push-pull switch 3 and the anti-misoperation switch 4. When the push-pull switch 3 and the anti-misoperation switch 4 are actuated in the interlayer, the protruding part of the auxiliary limiting elastic sheet 9 is embedded in the corresponding concave point, forming a stable limiting structure. This design not only improves the positioning accuracy of the push-pull switch 3 and the anti-misoperation switch 4 in the interlayer, but also ensures the stability of the actuation operation. At the same time, the cooperation of the concave point and the protruding part effectively prevents the switch from sliding or mispositioning in the interlayer, further enhancing the reliability and durability of the structure.
[0048] In the preferred embodiment, the surface of the push-pull switch 3 is provided with a push-pull actuator 30, which is clamped into the push-pull actuator 22 on the outside of the hatch cover 2, so that the actuation stroke of the push-pull switch 3 is limited. The shape of the push-pull actuator 30 matches the push-pull actuator 22, ensuring the stability during actuation. When the push-pull actuator 30 is actuated to the open position, the end of the push-pull switch 3 protrudes from the interlayer and is inserted into the socket on the shell 1, completing the locking of the hatch. When actuated to the closed position, the push-pull actuator 30 limits the stroke of the push-pull switch 3, preventing over-actuation. The surface of the anti-misoperation switch 4 is provided with an anti-misoperation actuator 40, which is clamped into the anti-misoperation actuator 23 on the outside of the hatch cover 2, so that the actuation stroke of the anti-misoperation switch 4 is limited. When the anti-misoperation actuator 40 is actuated to the open position, the anti-misoperation protrusion 41 of the anti-misoperation switch 4 is inserted into the anti-misoperation notch 32 on the push-pull switch 3, limiting the operation of the push-pull actuator 30 and preventing accidental opening of the hatch due to misoperation. Green arrows can be provided on the actuator to indicate the actuation direction, helping users to operate more intuitively. Red markings can be provided adjacent to the actuator (red markings are exposed when in the open state), reminding users of the state of the switch and preventing accidental opening of the hatch due to misactuation.
[0049] The utility model also provides a kind of equipment, uses the waterproof hatch structure described above, and the equipment specifically can be camera, or other need to be configured hatch equipment.
