Description

Technical Field

[0001] This utility model relates to the field of battery compartment technology, and in particular to a compartment structure and electronic product. Background Technology

[0002] As the energy source for most electronic products, the airtightness of the battery compartment is crucial. When the device is used in an environment with changes in temperature and air pressure, a near-sealed negative pressure cavity can easily form inside the battery compartment. Specifically, when attempting to open the compartment cover, due to the excellent seal, external air cannot flow in in time to balance the internal and external air pressure, resulting in a strong "suction cup effect" between the cover and the compartment body, making it more difficult to open the cover. Utility Model Content

[0003] The main purpose of this utility model is to provide a compartment structure that solves the technical problem that current compartment structures cannot balance the internal and external pressure difference, thus increasing the difficulty of opening the compartment cover.

[0004] To achieve the above objectives, the compartment structure proposed in this utility model includes: The main body of the compartment has a cavity; A door assembly includes a door body and a seal. One end of the seal is connected to the door body, and the other end of the seal abuts against the inner wall of the cavity. The door body is used to open or close the cavity. The door body has a ventilation gap that communicates with the outside. At least one airflow channel is provided in the main body of the door, and the airflow channel connects the cavity and the ventilation gap. Attached Figure Description

[0012] In existing technologies, the battery compartment's sealing is crucial, as it serves as the energy source for most electronic products. When a device is used in an environment with changing temperature and air pressure, a near-sealed negative pressure cavity can easily form inside the battery compartment. Specifically, when attempting to open the compartment cover, the excessively good seal prevents outside air from flowing in in time to balance the internal and external air pressure, resulting in a strong "suction cup effect" between the cover and the compartment body, thus increasing the difficulty of opening the cover.

[0013] This utility model proposes a compartment structure.

[0014] Please see Figures 1 to 4 In one embodiment of this utility model, the chamber structure includes: a chamber body 100, a door assembly, and at least one airflow channel 221. The chamber body 100 is provided with a cavity 110. The door assembly includes a door body 200 and a sealing element 300. One end of the sealing element 300 is connected to the door body 200, and the other end of the sealing element 300 abuts against the inner wall of the cavity 110. The door body 200 is used to open or close the cavity 110. The door body 200 has a ventilation gap 400 that connects to the outside. The airflow channel 221 is provided in the door body 200 and connects the cavity 110 and the ventilation gap 400.

[0015] It should be noted that the main body 100 of the compartment structure and the main body 200 of the door can be made of plastic or other plastic materials, mainly used in electronic products with battery compartments or those requiring both sealing and opening, such as audio equipment, televisions, air conditioners, and washing machines. The door assembly is adapted to the cavity 110 to facilitate opening or closing of the cavity 110.

[0016] In this embodiment, the cavity 110 is used to hold batteries. After the door assembly is installed on the main body 100 of the compartment, one end of the sealing element 300 is connected to the door body 200, and the edge of the other end abuts against the inner wall of the cavity 110. It can be understood that the sealing element 300 is annular, and the sealing element 300 and the door body 200 are fixed together by a convex and concave engagement. The sealing element 300 is made of silicone or plastic, has a certain degree of elasticity, and is used to ensure the sealing of the cavity 110. One end of the door body 200 is rotatably connected to the main body 100 of the compartment. By flipping the door body 200 and causing the sealing element 300 to move synchronously, the cavity 110 can be opened or closed.

[0017] The main body 200 of the gate has a ventilation gap 400 communicating with the outside. The ventilation gap 400 can be a gap between components in the main body 200 of the gate, or it can be a gap directly opened in the main body 200 of the gate, ensuring that it does not affect the sealing performance of the main body 200 of the gate or the sealing performance of the sealing element 300. Specifically, the ventilation gap 400 is a tiny gap formed on the structure of the main body 200 of the gate, communicating with the external environment. It is not a simple hole, but can be a non-straight-through multi-corner structure to prevent external water from directly spraying in. An airflow channel 221 is also provided on the side of the main body 200 of the door facing the cavity 110. The airflow channel 221 connects to the cavity 110 and extends along the main body 200 of the door and connects to the ventilation gap 400. Thus, the cavity 110 is connected to the outside through the airflow channel 221 and the ventilation gap 400. When the air pressure inside the cavity 110 changes, the airflow flows in the cavity 110 and the external environment to balance the air pressure inside and outside the cavity 110.

[0018] This utility model's technical solution ensures the sealing performance of the entire compartment by using a sealing element 300 of the door assembly to seal against the inner wall of the cavity 110 of the main body 100. Furthermore, it balances the air pressure between the cavity 110 and the outside by creating an airflow channel 221 and a ventilation gap 400 in the door body 200. Specifically, the ventilation gap 400 connects to the outside, and the airflow channel 221 connects to the cavity 110, with the ventilation gap 400 also connecting to the airflow channel 221. This allows the cavity 110 to connect with the outside. When the door body 200 is opened, the air pressure inside the cavity 110 changes, and external airflow enters the cavity 110 through the ventilation gap 400 and the airflow channel 221, thereby balancing the air pressure between the cavity 110 and the outside, facilitating the opening of the door assembly. Moreover, the airflow channel 221 does not disrupt the seal between the sealing element 300 and the cavity 110, ensuring the air pressure balance while maintaining the cavity 110's seal, thus facilitating the opening of the door body 200.

[0019] In one embodiment, the main body 200 of the door includes an outer cover 210 and an inner cover 220. The inner cover 220 is disposed inside the outer cover 210. The wall surface of the outer cover 210 facing the inner cover 220 and the inner cover 220 are spaced apart to form a door cavity 230. The peripheral wall of the inner cover 220 and the inner side wall of the outer cover 210 are spaced apart to form a first air gap 410. The first air gap 410 forms a ventilation gap 400. An airflow channel 221 is disposed in the inner cover 220, and the door cavity 230 connects the airflow channel 221 and the ventilation gap 400.

[0020] The outer cover 210 serves as the exterior component of the main body 200 of the storage door, forming its shape. The inner cover 220 is located inside the outer cover 210 and is used to fix and install the sealing element 300. The inner cover 220 and the outer cover 210 can be connected by snap-fit ​​or by screws or other connecting parts; this is not limited here. It should be noted that there is a first air gap 410 between the inner cover 220 and the outer cover 210, which forms a ventilation gap 400 and communicates with the outside. In a specific implementation, the outer cover 210 covers the inner cover 220, and the two together form the inner cavity 230 of the storage door. There is a gap between the edge of the inner cover 220 and the inner wall of the outer cover 210, which serves as the first air gap 410. Furthermore, the first air gap 410 is provided on a portion extending circumferentially from the outer cover 210 and the inner cover 220, or the first air gap 410 can be provided around the entire circumference of the outer cover 210 and the inner cover 220. (Reference) Figure 1 As shown, the opening end of the first air gap 410 is located below the main body 200 of the door. External water flow will not easily enter the first air gap 410. Even if water flow does enter, it will be deposited inside the inner cavity 230 of the door and will not enter the cavity 110, so it will not affect the sealing performance of the door assembly.

[0021] At the moment the door is opened, the negative pressure formed inside the cavity 110 is first drawn out from the inner cavity 230 of the door through the airflow channel 221, causing a decrease in pressure inside the inner cavity 230. Then, air is drawn in from the external environment through the first air gap 410, i.e., the ventilation gap 400, to replenish the pressure and balance the airflow. External water entering the cavity 110 must pass sequentially through the narrow first air gap 410, the inner cavity 230 of the door, and the airflow channel 221. Compared to directly creating a channel in the main body 200 of the door, this path provides a certain degree of sealing, ensuring ventilation while significantly improving the overall waterproofing capability.

[0022] Furthermore, the inner wall of the main body 100 of the compartment is provided with a limiting step 120, the outer cover 210 and the limiting step 120 are spaced apart to form a second air gap 420, and the outer wall of the outer cover 210 and the inner wall of the main body 100 of the compartment are spaced apart to form a third air gap 430. The first air gap 410, the second air gap 420 and the third air gap 430 together form a ventilation gap 400.

[0023] In the specific implementation process, the inner wall of the main body 100 of the compartment has a limiting step 120. A part of the side wall of the main body 100 of the compartment forms a cavity 110 on one side of the limiting step 120, and another part forms a groove on the other side of the limiting step 120. The cavity 110 is used to place the battery. The main body 200 of the compartment door is located in the groove. The inner wall of the groove surrounds the outer periphery of the outer cover 210, and a third air gap 430 is formed between the two. The limiting step 120 surrounds the inner wall of the cavity 110. On the one hand, when the compartment door assembly is closed, the end face of the inner cover 220 or the outer cover 210 abuts against the limiting step 120, thereby playing a limiting role and indicating the closed position of the compartment door; on the other hand, a second air gap 420 is formed between the limiting step 120 and the outer cover 210. The first air gap 410, the second air gap 420 and the third air gap 430 are connected. Among them, the third air gap 430 is connected to the outside, and the first air gap 410 is connected to the inner cavity of the compartment. Thus, the ventilation gap 400 is not a single gap, but a tortuous channel formed by three consecutive air gaps connected in series. External air must pass through these three air gaps in sequence before entering the inner cavity 230 of the compartment. This tortuous channel creates multiple barriers to the flow of external water. Even if a small amount of water enters the third air gap 430, it is difficult for it to penetrate further and is effectively blocked, thereby achieving the effect of "ventilation but basically impermeability".

[0024] refer to Figure 2 and Figure 3 As shown, in one embodiment, the door body 200 is provided with a guide groove 222 that communicates with the airflow channel 221. The guide groove 222 is located on the side of the door body 200 facing the cavity 110.

[0025] In the specific implementation, the inner cover 220 is positioned facing the cavity 110, and the guide groove 222 is disposed on the surface of the inner cover 220 facing the cavity 110. The guide groove 222 is directly connected to one end of the airflow channel 221. The guide groove 222 can be a pit, a groove, or a combination thereof, and its volume and area are larger than the cross-sectional area of ​​the airflow channel 221. The air flowing out of the airflow channel 221 first enters the relatively large guide groove 222, avoiding the risk that the outlet is too small and easily blocked by the slight deformation of the seal 300 itself or by foreign objects, thus ensuring the reliability of airflow.

[0026] In one embodiment, the sealing member 300 includes an abutment portion 320 and a connecting portion 310. The abutment portion 320 abuts against the inner wall of the cavity 110, and the connecting portion 310 is connected to the door body 200. The connecting portion 310 is provided with a groove 311 that communicates with the guide groove 222.

[0027] In this embodiment, when the door is closed, the abutment portion 320 elastically compresses against the inner wall of the cavity 110, forming a dynamic sealing interface, which is the core of the waterproof seal. The inner cover 220 of the door body 200 has a protrusion, and the connecting portion 310 is adapted to the protrusion with a recess, and is inserted into the protrusion to achieve the installation of the sealing element 300. The connecting portion 310 has a groove 311 on its side wall away from the abutment portion 320. The groove 311 is opposite to and communicates with the guide groove 222 to expand the airflow area. Furthermore, the groove 311 being located on one side of the sealing element 300 also ensures the aesthetic appearance.

[0028] It should be noted that one or more airflow channels 221 are provided in the main body 200 of the door, and correspondingly, the inner cover 220 is provided with a corresponding guide groove 222, and the sealing element 300 is provided with a corresponding groove 311.

[0029] In one embodiment, the door assembly further includes a cover plate 500, which is fixedly disposed on the door body 200 and is located on the side of the guide groove 222 facing the cavity 110, and is used to cover the guide groove 222.

[0030] In practice, the cover plate 500 is fixed to the side of the main body 200 of the compartment door (i.e., the inner cover 220) facing the cavity 110 by means of snap fasteners 241, welding, or screws. The cover plate 500 can also record information or a logo. The cover plate 500 also conceals the side of the guide groove 222 facing the cavity 110 to ensure overall aesthetics, allowing airflow to pass between the groove 311 and the guide groove 222.

[0031] refer to Figure 1 and Figure 2 As shown, in one embodiment, the main body 200 of the door also includes a connecting plate 240, which is slidably disposed in the inner cavity 230 of the door. The connecting plate 240 is provided with a buckle 241, which is used to engage with the main body 100 of the compartment.

[0032] Specifically, the connecting plate 240 is slidably disposed within the inner cavity 230 of the door formed by the outer cover 210 and the inner cover 220. The connecting plate 240 can perform a limited range of translational movement within the inner cavity 230, and the sliding connection can be achieved through structures such as guide rails and slide grooves (not shown). The buckle 241 is located at one end of the connecting plate 240 and passes through a pre-reserved opening on the outer cover 210 to engage with the main body 100 of the compartment, thereby achieving a limiting engagement between the door assembly and the main body 100 of the compartment.

[0033] When the user closes the compartment door, a certain area of ​​the drive cover 210 can drive the internal connecting plate 240 to slide, thereby causing the latch 241 to move synchronously and engage with the corresponding latching structure (such as a latching hole) on the compartment body 100, thus achieving a secure lock between the compartment door assembly and the compartment body 100. To unlock, a certain area of ​​the drive cover 210 is typically used to drive the connecting plate 240 to slide in the opposite direction, causing the latch 241 to disengage.

[0034] In specific implementation, the connecting plate 240 is also provided with a driving part 242, and the outer cover 210 is provided with a clearance opening 211. The driving part 242 extends to the outside through the clearance opening 211, and pushing the driving part 242 causes the latch 241 to disengage from the compartment body 100. The driving part 242 is a part of the connecting plate 240, specifically, such as a button, push handle, or boss extending from the connecting plate 240. At the corresponding position on the outer cover 210, the clearance opening 211 is provided. The size and shape of the clearance opening 211 allow the driving part 242 to pass through and have sufficient space to allow the driving part 242 to move. The driving part 242 extends to the outside of the outer cover 210, so that it can be directly touched and operated. When it is necessary to open the compartment door, pushing the exposed driving part 242 causes the connecting plate 240 to slide within the compartment door cavity 230. The sliding of the connecting plate 240 causes the latch 241 to move synchronously. When it slides to a specific position, the latch 241 disengages from the engagement with the main body 100 of the compartment. It can be understood that the connecting plate 240 can be reset by pushing the drive unit 242 in the opposite direction, or it can be automatically reset by setting an elastic element such as a spring.

[0035] In one embodiment, the inner wall of the main body 100 of the compartment is provided with a limiting part 130, which is connected to the limiting step 120. The limiting part 130 surrounds the outer periphery of the outer cover 210. The limiting part 130 has a slot 131, and the buckle 241 engages with the slot 131 to make the connection engage with the main body 100 of the compartment.

[0036] A limiting part 130 is integrally formed on the inner wall of the cavity 110 of the main body 100 of the storage compartment, and the limiting part 130 is connected to the limiting step 120. Specifically, the limiting part 130 is located on the side of the limiting step 120 away from the cavity 110, and surrounds the outer periphery of the outer cover 210 of the main body 200 of the storage door. When the storage door is closed, at least a portion of the outer cover 210 is surrounded by the limiting part 130. One or more slots 131 are provided on the limiting part 130, and the shape of the slots 131 matches the shape of the buckles 241 on the connecting plate 240. When the storage door reaches the closed position, the end of the buckle 241 is precisely engaged in the slot 131 on the limiting part 130, thereby achieving engagement.

[0037] This utility model also proposes an electronic product, which includes a compartment structure. The specific structure of the compartment structure is as described in the above embodiments. Since this electronic product adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The compartment structure is used to hold devices such as batteries. The electronic product mainly involves devices such as audio equipment, televisions, air conditioners, and washing machines. For example, an audio product has a removable battery and a battery compartment for holding the battery. Due to limitations in the overall waterproof performance and appearance requirements of the battery compartment, it is not possible to directly add an exhaust structure to the outside of the battery door assembly; it is also limited by the airtightness requirements of the audio cavity, making it impossible to directly add an exhaust structure inside (direct opening would damage the airtightness of the acoustic cavity and affect sound quality). Thus, this compartment structure can meet the airtightness requirements and also facilitates opening the battery compartment cover without affecting the sound quality of the audio equipment.

[0038] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
