Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a dehumidification device, a battery and an electrical device. Background Art

[0002] A battery is a modular unit formed by combining multiple battery cells. A battery usually includes a housing, battery cells, etc. Multiple battery cells are connected in series and in parallel and arranged in the limited accommodation space of the housing. During the use of the battery, the humidity inside the battery increases significantly due to changes in its internal and external environment. Excessive humidity inside the battery will cause problems such as rust and short circuit inside the battery, thereby affecting the service life of the battery. Therefore, a drying component must be installed inside the battery. The drying component is usually provided with a desiccant to adjust the humidity inside the battery.

[0003] Since the desiccant's drying performance will change significantly due to the influence of humidity and time, the desiccant needs to be replaced regularly to ensure its own drying performance is good and to ensure the drying effect inside the battery.

[0004] In the related art, the drying component is arranged inside the battery case, and the changes of the desiccant are not easily observed outside the battery case. If the failed or degraded desiccant is not replaced in time, the humidity inside the battery will increase, thereby increasing the risk of battery damage. Utility Model Content

[0005] The purpose of the present application is to provide a dehumidification device, a battery and an electrical device, aiming to solve the technical problem that it is difficult to observe the state of the desiccant component in the battery, thereby delaying the replacement of the desiccant and causing the humidity inside the battery to increase.

[0009] In this example, the desiccant is contained in the drying component to achieve the purpose of absorbing moisture and drying. In addition, by providing a light guide component, even when the light in the drying chamber is insufficient, the light guide component can guide the light into the drying chamber through the light guide entrance, so that the light in the drying chamber is supplemented, so that the operator can clearly observe the state of the desiccant in the drying chamber through the light guide entrance, so as to accurately and timely determine whether the desiccant needs to be replaced, thereby achieving the purpose of timely replacing the failed desiccant, ensuring the dehumidification and drying performance of the dehumidification device, reducing the risk of battery damage, and increasing the battery life.

[0011] In this example, a light guiding channel is opened on the main body structure, and a light guiding structure is arranged in the light guiding channel, so that light can enter the light guiding channel from the light guiding entrance along the extension direction of the light guiding channel, and be emitted from the light guiding exit and into the drying chamber through the light guiding effect of the light guiding structure, thereby enhancing the brightness in the drying chamber, making it easier for the operator to observe the state of the desiccant in sufficient light, so as to facilitate timely replacement of the desiccant.

[0012] In one embodiment, the main body structure is cylindrical, and the cylindrical cavity of the main body structure forms the light guiding channel.

[0013] In this example, the cylindrical main body structure is easy to manufacture, and the cylindrical cavity can form a light-guiding channel.

[0022] In one embodiment, the scattering component includes a scattering lens, which is connected to the main body structure and covers the light guide outlet.

[0023] In this example, the scattering lens has a simple structure and is easy to manufacture. The scattering lens covers the light guide outlet.

The container body containing the desiccant and the mounting seat are detachably connected. After the container body and the mounting seat are disassembled, the desiccant in the container body can be replaced, making the process of replacing the desiccant in the drying component more convenient.

[0026] In one embodiment, a plurality of communication holes are provided on the accommodating body, and the communication holes are arranged to pass through the cavity wall of the drying cavity.

[0027] In this example, the connecting holes are used to exchange flow between the space of the drying chamber and the space outside the accommodating body, so that moisture or water in the external space can enter the drying chamber, and the gas dried by the desiccant can re-enter the external space through the connecting holes, thereby achieving the purpose of drying through flow exchange.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0071] A battery is a modular unit formed by combining multiple battery cells. A battery usually includes a box, battery cells, etc. Multiple battery cells are connected in series and in parallel and arranged in a limited space in the box. The battery cells are electrically connected through a busbar, which is usually made of metal. In addition, there are many other metal parts inside the battery box.

[0072] During the use of the battery, the humidity inside the battery increases significantly due to changes in its internal and external environment. Excessive humidity inside the battery will cause problems such as rust and short circuit inside the battery, causing battery damage, thereby affecting the battery life. Therefore, a drying component must be installed inside the battery. The drying component is usually provided with a desiccant to adjust the humidity inside the battery.

[0073] Since the desiccant is affected by humidity and time, its own drying performance will change greatly. After the desiccant absorbs too much moisture, the water inside the desiccant tends to be saturated, and its water absorption or moisture absorption capacity will be significantly reduced, and the desiccant may even become ineffective. Therefore, the desiccant needs to be replaced regularly to ensure its own drying performance is good and to ensure the drying effect inside the battery.

[0074] For desiccant, the color of desiccant will change after absorbing water. The color change of desiccant usually means adding an indicator to the desiccant. The indicator can change color as the amount of water absorbed by the desiccant changes. The different color changes can also reflect the different amount of moisture absorbed by the desiccant. When the color of the desiccant changes to a certain extent, it means that it has reached a saturated state, that is, the desiccant can no longer absorb more water, which is equivalent to the desiccant losing its drying ability and becoming ineffective.

[0075] In the related art, the drying component is arranged inside the battery box, and the changes of the desiccant are not easily observed outside the box; if the failed or degraded desiccant is not replaced in time, the humidity inside the battery will increase, thereby increasing the risk of battery damage and affecting the battery life.

[0076] Therefore, the present application provides a dehumidification device 1130, which is used to be installed on the battery 1100. The dehumidification device 1130 is provided with a light guide entrance 11311 and a light guide component 1131, so that light can enter the light guide component 1131 through the light guide entrance 11311, and guide the light into the drying chamber 11324 through the light guide component 1131, so that the operator can easily observe the drying component 1132 and the drying chamber 11324 in the drying component 1132. The drying chamber 11324 is used to place the desiccant, so the state of the desiccant can be observed. The operator can determine whether the desiccant needs to be replaced according to the state of the desiccant, thereby achieving the purpose of timely replacing the failed desiccant and reducing the risk of damage to the battery 1100.

[0077] The dehumidification device 1130 provided in the present application is applied to the battery 1100. Specifically, refer to Figure 2 and Figure 3As shown, an embodiment of the present application provides a battery 1100, which may include a battery cell 1120. The battery 1100 disclosed in the embodiment of the present application may be used in an electrical device that uses the battery 1100 as a power source or various energy storage systems that use the battery 1100 as an energy storage element. The electrical device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Among them, the electric toy may include a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, an electric airplane toy, and the like, and the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, and the like.

[0078] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0079] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 1100 is provided inside the vehicle 1000, and the battery 1100 may be provided at the bottom, head or tail of the vehicle 1000. The battery 1100 may be used to power the vehicle 1000, for example, the battery 1100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 1200 and a motor 1300, and the controller 1200 is used to control the battery 1100 to power the motor 1300, for example, for starting, navigating and driving the vehicle 1000.

[0080] In some embodiments of the present application, the battery 1100 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0081] Please refer to Figure 2 and Figure 3 As shown, Figure 2 A schematic diagram of the structure of the exterior of a battery 1100 provided in some embodiments of the present application, Figure 3 The exploded diagram of the battery 1100 provided in some embodiments of the present application. The battery 1100 includes a box body 1110 and a battery cell 1120. The battery cell 1120 is accommodated in the box body 1110. The battery cells 1120 are connected in series, in parallel or in mixed connection to form a battery 1100 module. Figure 3 The box 1110 is used to provide a containing space 1113 for the battery module 1100 or the battery cell 1120, and the box 1110 can adopt a variety of structures.

[0082] The battery cell 1120 refers to the smallest unit constituting the battery 1100. Each battery cell 1120 may be a secondary battery cell 1120 or a primary battery cell 1120; it may also be a lithium-sulfur battery cell, a sodium-ion battery cell or a magnesium-ion battery cell, but is not limited thereto. The battery cell 1120 may be cylindrical, flat, rectangular or in other shapes.

[0083] According to some embodiments of the present application, referring to Figure 4 and Figure 5 The embodiment of the present application provides a dehumidification device 1130, which includes a drying component 1132 and a light guide component 1131. The drying component 1132 is formed with a drying chamber 11324. The light guide component 1131 is connected to the drying component 1132, and a light guide inlet 11311 is provided on the light guide component 1131. The light guide component 1131 is used to guide light from the light guide inlet 11311 to the drying chamber 11324.

[0084] Specifically, the drying component 1132 is used to hold the desiccant and plays a supporting role for the desiccant. A drying cavity 11324 is formed on the drying component 1132, and part or all of the desiccant is placed in the drying cavity 11324. For example, the drying component 1132 adopts a shell structure, and the drying cavity 11324 is formed in the middle of the shell structure. The drying cavity 11324 can be groove-shaped, that is, the drying cavity 11324 forms a groove space, and the desiccant can be completely accommodated in the groove space, or part of the desiccant can protrude outside the groove of the groove space. The groove forms the cavity opening of the drying cavity 11324, which is also the entrance for light to enter the drying cavity 11324 after passing through the light guide component 1131. The groove or cavity opening is an observation port on the drying component 1132 that can directly observe the interior of the drying cavity 11324 (specifically, observe the desiccant inside the drying cavity 11324).

[0085] The desiccant is mainly used to absorb moisture, water vapor, etc. inside the battery 1100 to reduce the risks of rust, short circuit, performance degradation, etc. caused by water vapor, etc. inside the battery 1100. The desiccant may include a combination of one or more of a silica gel desiccant, a molecular sieve desiccant, a soda lime desiccant, an activated alumina desiccant, anhydrous sodium sulfide desiccant, a color-changing desiccant, etc., wherein the color-changing desiccant usually contains a chemical indicator, and the color will change after absorbing water. For example, the desiccant changes from blue to pink, which can intuitively display the status of the desiccant.

[0086] For the light guide component 1131, the interior of the drying chamber 11324 can be directly observed through the light guide entrance 11311. The light guide entrance 11311 can be understood as an observation port. However, since the dehumidification device 1130 is installed on the battery 1100, and the battery 1100 can be installed in the vehicle 1000, and the battery 1100 is generally installed at the bottom of the vehicle 1000 or inside the vehicle 1000, the light around the battery 1100 is dim. Only the light guide entrance 11311 or the observation port is provided, and it is not possible to clearly observe the situation inside the drying chamber 11324. Therefore, the light guide component 1131 should also have It has the function of guiding light. The light can enter the light guide component 1131 through the light guide entrance 11311. The light guide component 1131 guides the light so that the light can enter the drying chamber 11324 through the cavity mouth or the slot under the guidance of the light guide component 1131. The drying chamber 11324 is provided with a desiccant. Therefore, the operator can clearly observe the state of the desiccant in the drying chamber 11324 through the light guide entrance 11311 in sufficient light, so as to more accurately judge whether the desiccant needs to be replaced, thereby achieving the purpose of timely replacing the failed desiccant and reducing the risk of damage to the battery 1100.

[0087] In addition, since the interior of the battery 1100 needs to be isolated from the external space when the dehumidification device 1130 is assembled on the battery 1100, the light guide inlet 11311 needs to be light-transmitting and sealed. Therefore, a light-transmitting structure can be set on the light guide inlet 11311. For example, the light-transmitting structure can adopt transparent lenses, transparent glass sheets, transparent plastic sheets, etc. The drying component 1132 is set inside the box body 1110 of the battery 1100, and the drying component 1132 or the light guide component 1131 is connected to the box body 1110 of the battery 1100. A sealing structure needs to be set at the connection position to ensure the isolation of the inside and outside of the battery 1100.

[0088] The connection method between the drying component 1132 and the light guide component 1131 can be a fixed connection or a detachable connection. In the fixed connection method, the drying component 1132 can be integrally formed with the light guide component 1131 or connected by welding. In the detachable connection method, the drying component 1132 can be connected to the light guide component 1131 by threaded connection, limit plug-in, lock connection, etc.

[0089] When the dehumidification device 1130 is installed with the battery 1100, the drying component 1132 must be inside the battery 1100 (that is, inside the subordinate accommodating space 1113), and the light guide entrance 11311 of the light guide component 1131 must at least be exposed to the outside of the battery 1100 to facilitate observation by the operator and allow light to enter the light guide component 1131 through the light guide entrance 11311.

[0090] In this example, the dehumidification device 1130 contains desiccant through the drying component 1132 to achieve the purpose of absorbing moisture and drying. In addition, by providing the light guide component 1131, even when the light in the drying chamber 11324 is insufficient, the light guide component 1131 can guide the light into the drying chamber 11324 through the light guide entrance 11311, so that the light in the drying chamber 11324 is supplemented, so that the operator can clearly observe the state of the desiccant in the drying chamber 11324 through the light guide entrance 11311, so as to accurately and timely determine whether the desiccant needs to be replaced, thereby achieving the purpose of timely replacing the failed desiccant, ensuring the dehumidification and drying performance of the dehumidification device 1130, reducing the risk of damage to the battery 1100, and increasing the service life of the battery 1100.

[0091] In some examples, reference Figure 5 and Figure 6 As shown, the light guide component 1131 includes a main body structure 11315 and a light guide structure 11313, a light guide channel 11312 is formed on the main body structure 11315, a light guide entrance 11311 is formed on the light guide channel 11312, the light guide channel 11312 also has a light guide exit 11314, the light guide exit 11314 is arranged opposite to the drying chamber 11324 so that light can be guided into the drying chamber 11324, and the light guide structure 11313 is arranged in the light guide channel 11312.

[0092] Specifically, the main body structure 11315 can adopt a solid structure or a shell structure, and the light guide channel 11312 is extended from the light guide entrance 11311 toward the direction close to the drying chamber 11324 to form a light guide path. It can be understood that the light guide channel 11312 has a light guide exit 11314 and a light guide entrance 11311, so that light can enter the light guide channel 11312 through the light guide entrance 11311 and be emitted from the light guide channel 11312 through the light guide exit 11314. Therefore, it can be known that the light guide entrance 11311 can be understood as the channel entrance of the light guide channel 11312, and the light guide exit 11314 can be understood as the channel exit of the light guide channel 11312. The light guide entrance 11311 can be understood as the entrance for light to enter the interior of the light guide channel 11312, and the light guide exit 11314 can be understood as the exit for light to emit from the light guide channel 11312.

[0093] The light-guiding channel 11312 may be a hole structure or a groove structure opened on the main body structure 11315, the extension direction of the central axis of the hole structure is the light-guiding path, and the extension direction of the notch of the groove structure is the light-guiding path; when the light-guiding channel 11312 is a groove structure, when the dehumidification device 1130 is assembled with the box body 1110 of the battery 1100, the light-guiding channel 11312 may be located outside the box body 1110, and a light-transmitting sealing treatment is required between the groove structure and the accommodating space 1113 of the box body 1110, for example, a light-transmitting sheet is provided on the light-guiding outlet 11314 of the groove structure at the position connected to the drying chamber 11324.

[0094] The light guide structure 11313 can be a combination of one or more of a light guide plate, a lens, a light guide sheet, a strip light guide structure, an optical coating, an optical film (such as a light guide film), etc., wherein the above light guide structures 11313 have the function of reflecting and refracting light, so that the light can be transmitted along the light guide channel 11312. When the light guide structure 11313 adopts an optical film, the light guide structure 11313 can be directly attached to the channel wall of the light guide channel 11312, and the light guide structure 11313 and the light guide channel 11312 are connected. The channel walls of the light guide channel 11312 can be bonded by an adhesive structure; when the light guide structure 11313 uses an optical coating, the light guide structure 11313 can be painted on the channel wall of the light guide channel 11312, so that the structure of the light guide component 1131 is simpler and easier to manufacture, which is conducive to reducing costs; when the light guide structure 11313 uses a light guide plate, a lens, a light guide sheet, or a strip light guide structure, it can be connected to the channel wall by bonding, or it can also be detachably connected to the channel wall through a connecting component. The light guide structure 11313 can cover all or part of the channel wall, so that light can enter from the light guide entrance 11311, exit from the light guide exit 11314 and shoot toward the drying chamber 11324.

[0095] In this example, the light guide component 1131 opens a light guide channel 11312 on the main body structure 11315 and sets a light guide structure 11313 in the light guide channel 11312, so that light can enter the light guide channel 11312 along the extension direction of the light guide channel 11312 through the light guide entrance 11311, and is emitted from the light guide outlet 11314 and into the drying chamber 11324 through the light guiding effect of the light guide structure 11313, thereby enhancing the brightness in the drying chamber 11324, making it easier for the operator to observe the status of the desiccant in sufficient light so as to facilitate timely replacement of the desiccant.

[0096] In some examples, reference Figure 5 and Figure 6 As shown, the main body structure 11315 is cylindrical, and the cylindrical cavity of the main body structure 11315 forms a light guiding channel 11312.

[0097] Specifically, the main body structure 11315 can adopt a cylindrical structure, the middle of the cylindrical structure forms a cylindrical cavity, and the two ends of the cylindrical structure along the central axis form openings, wherein the opening away from the drying component 1132 forms the light guide entrance 11311, and the opening close to the drying component 1132 and opposite to the cavity opening of the drying cavity 11324 forms the light guide exit 11314; the cross-sectional outer contour of the main body structure 11315 can be circular, elliptical or polygonal, etc. The light guide structure 11313 can be installed on the cavity wall of the cylindrical cavity.

[0098] In this example, the cylindrical main body structure 11315 is easy to manufacture, and the cylindrical cavity can form the light guiding channel 11312. The cylindrical main body structure 11315 is conducive to reducing the weight of the dehumidification device 1130 and achieving lightweight of the dehumidification device 1130.

[0099] In some examples, reference Figure 6 As shown, the light guide structure 11313 includes a light guide film, and the light guide film is connected to the inner wall of the light guide channel 11312.

[0100] Specifically, the light-guiding film is an independent sheet structure, or the light-guiding film can also be a film layer structure formed by brushing on the inner wall of the channel. The light-guiding film is a film body made of a high-reflectivity material, or the light-guiding film is a layer of high-reflectivity film plated on the inner wall of the channel. The light-guiding film is thin and will not increase much weight and volume, which is convenient for production and installation, and is conducive to reducing weight, making the structure of the light-guiding component 1131 compact. The sheet-like light-guiding film is also easy to cut according to the shape and size of the light-guiding channel 11312, and has stronger adaptability. The light-guiding film can cover all or part of the surface of the inner wall of the channel, so that light can be transmitted from the light-guiding entrance 11311 to the light-guiding exit 11314 along the extension direction of the light-guiding channel 11312.

[0101] In this example, the light-guiding film has a strong light-reflecting effect. The light-guiding film is easy to manufacture and connect with the inner wall of the channel, and is beneficial for reducing weight and saving space. The setting is more flexible and the adaptability is stronger.

[0102] In some examples, reference Figure 6 As shown, the dehumidification device 1130 also includes a focusing component 1133 , which is connected to the main structure 11315 and disposed at the light guide inlet 11311 .

[0103] Specifically, the light guide entrance 11311 is the channel entrance, and the light guide entrance 11311 is the starting position for light to enter the light guide channel 11312. The more light and the more concentrated it is that enters the light guide channel 11312, the more light and the more sufficient it is that is emitted from the light guide outlet 11314, and the more sufficient the light that enters the drying chamber 11324, the more obvious the lighting effect.

[0104] Therefore, a focusing component 1133 is installed on the light guide entrance 11311, and the focusing component 1133 can be detachably connected to the main structure 11315, for example, by bonding, threaded connection, limit plug-in, etc.; the function of the focusing component 1133 is to converge and collect light, thereby improving the efficiency of light utilization. The focusing component 1133 needs to have strong light transmittance, so that the light can be transmitted into the light guide channel 11312 after being converged by the focusing component 1133.

[0105] The focusing component 1133 can be made of optical grade PC (polycarbonate) or acrylic material, etc. Optical grade PC has high transparency, low dispersion, good physical strength and impact resistance, which is beneficial to improving the transmittance and focusing effect of the focusing component 1133.

[0106] In this example, by setting a focusing component 1133 at the light guide entrance 11311, the focusing component 1133 can converge the light, so that more light can enter the light guide channel 11312, and then enter the drying chamber 11324, thereby improving the light intensity and brightness in the drying chamber 11324, so that the operator can observe the desiccant under conditions of more sufficient light, thereby improving the clarity of observation of the desiccant.

[0107] In some examples, reference Figure 6 As shown, the focusing assembly 1133 includes a focusing lens, which is connected to the main structure 11315 and covers the light guide entrance 11311.

[0108] Specifically, a focusing lens is an optical element. The function of the focusing lens is to converge light or change the propagation direction of light. The focusing lens can adopt a transparent sheet structure. For example, the focusing lens can adopt a combined lens formed by a convex lens, a concave lens or other combinations; the material of the focusing lens can be optical grade glass, optical grade plastic, crystal material (such as silica material), etc.

[0109] The focusing lens cover is arranged at the light guide entrance 11311, which means that the focusing lens covers the light guide entrance 11311, so that the incident light can be irradiated on the focusing lens at the position of the light guide entrance 11311. For example, when the focusing lens is in a sheet shape, the transmission surface of the focusing lens covers the light guide entrance 11311.

[0110] The focusing assembly 1133 may also include a focusing bracket, and the focusing lens can be installed on the focusing bracket, which is then connected to the main body structure 11315. The focusing bracket and the main body structure 11315 can be connected by threaded connection, snap-on connection, limited insertion, etc.

[0111] In this example, the focusing lens has a simple structure and is easy to manufacture. The focusing lens covers the light guide entrance 11311, and converges and changes the light path, so that more light can be irradiated onto the light guide structure 11313, thereby guiding more light, which is beneficial to improving the intensity of light emitted from the light guide exit 11314, improving the efficiency of light collection and utilization, and improving the lighting effect of the drying chamber 11324.

[0112] In some examples, reference Figure 6 As shown, the dehumidification device 1130 also includes a scattering component 1134 , which is connected to the main structure 11315 and is disposed at the light guide outlet 11314 .

[0113] Specifically, the light guide channel 11312 has a light guide entrance 11311 and a light guide exit 11314. The light guide entrance 11311 is the light guide entrance 11311, and the light guide exit 11314 is the channel exit. The scattering component 1134 is arranged on the light guide exit 11314 so that the light from the light guide exit 11314 can be emitted through the scattering component 1134. The function of the scattering component 1134 is to change the propagation path of the light, turn the incident light to a different direction, and diffuse the light. After diffusion, the light can cover more areas in the drying chamber 11324, and the scattered light is more uniform, so that the field of view is clearer, so that the desiccant in the drying chamber 11324 can be more clearly observed.

[0114] In this example, the scattering component 1134 can diffuse and homogenize the light emitted from the light guide channel 11312 (or emitted into the drying chamber 11324), so that the light irradiated into the drying chamber 11324 is more uniform and the irradiated area is wider, so that the operator can more clearly observe the state of the desiccant in the drying chamber 11324.

[0115] In some examples, reference Figure 6 As shown, the scattering component 1134 includes a scattering lens, which is connected to the main structure 11315 and covers the light guide outlet 11314.

[0116] Specifically, a scattering lens is an optical element. The function of the scattering lens is to change the propagation direction of light and diffuse the light, making the light more uniform and reducing reflection and glare. The scattering lens can adopt a transparent sheet structure. For example, the scattering lens can adopt a convex lens, a concave lens or a combination lens formed by other combinations; the material of the scattering lens can be optical grade glass, optical grade plastic (such as polycarbonate, etc.), crystal material (such as silica material, etc.), etc.

[0117] The scattering lens cover is arranged at the light guide outlet 11314, which means that the scattering lens covers the light guide outlet 11314, so that the light from the light guide channel 11312 can be irradiated on the scattering lens at the position of the light guide outlet 11314. For example, when the scattering lens is in the form of a sheet, the transmission surface of the scattering lens covers the light guide outlet 11314.

[0118] The scattering component 1134 may also include a scattering bracket, and the scattering lens can be installed on the scattering bracket, which is then connected to the main structure 11315. The scattering bracket and the main structure 11315 can be connected by threaded connection, snap-on connection, limit-locking connection, etc.

[0119] In this example, the scattering lens has a simple structure and is easy to manufacture. The scattering lens covers the light guide outlet 11314 . The scattering lens changes the light path and diffuses the light so that the light can be more evenly irradiated into the drying chamber 11324 , thereby helping to improve the lighting effect on the drying chamber 11324 .

[0120] In some examples, reference Figure 5 and Figure 7 As shown, the drying component 1132 includes a mounting seat 11322 and a receiving body 11323 detachably connected to the mounting seat 11322, a drying chamber 11324 is formed on the receiving body 11323, an incident port connected to the drying chamber 11324 is opened on the receiving body 11323, the light guide component 1131 is connected to the mounting seat 11322, light is emitted from the incident port into the drying chamber 11324, and the incident port corresponds to the light guide entrance 11311.

[0121] Specifically, the accommodating body 11323 can accommodate a desiccant, a drying chamber 11324 is provided on the accommodating body 11323, the desiccant is accommodated in the drying chamber 11324, the drying chamber 11324 has a cavity opening, the cavity opening is the incident port of the drying chamber 11324, the incident port is provided on the accommodating body 11323, the incident port is connected with the drying chamber 11324, the incident port is also provided corresponding to the light guide entrance 11311 and the light guide exit 11314 of the light guide assembly 1131 (specifically the body structure 11315), and the incident port can also be provided opposite to and connected to the light guide exit 11314. The accommodating body 11323 can adopt a shell-like structure, the drying chamber 11324 is a groove provided on the accommodating body 11323, and the notch of the groove is the incident port.

[0122] The accommodating body 11323 can be detachably connected to the mounting seat 11322, so that the accommodating body 11323 and the mounting seat 11322 can be disassembled and separated from each other. After the accommodating body 11323 is separated from the mounting seat 11322, the desiccant in the accommodating body 11323 can be replaced, making it more convenient to replace the desiccant. When the dehumidification device 1130 is assembled with the box body 1110 of the battery 1100, the mounting seat 11322 can be connected to the box body 1110, and the accommodating body 11323 may not be in contact with or connected to the box body 1110, thereby protecting the accommodating body 11323.

[0123] When the drying component 1132 is connected to the light guide component 1131, the mounting seat 11322 is connected to the main body structure 11315 in the light guide component 1131. The main body structure 11315 and the mounting seat 11322 can be fixedly or detachably connected. For example, the main body structure 11315 and the mounting seat 11322 can be integrally formed, welded, threaded, limitedly plugged, or snap-locked.

[0124] In this example, the light guide component 1131 only needs to be connected to the mounting seat 11322 to achieve connection with the drying component 1132. The accommodating body 11323 for accommodating the desiccant and the mounting seat 11322 are detachably connected. After the accommodating body 11323 and the mounting seat 11322 are disassembled, the desiccant in the accommodating body 11323 can be replaced, making the process of replacing the desiccant in the drying component 1132 more convenient.

[0125] In some examples, reference Figure 7-9 As shown, a plurality of communication holes 11321 are provided on the accommodating body 11323 , and the communication holes 11321 are arranged to pass through the cavity wall of the drying cavity 11324 .

[0126] Specifically, the connecting hole 11321 passes through the cavity wall of the drying cavity 11324. It can be seen that the connecting hole 11321 connects the drying cavity 11324 with the space outside the accommodating body 11323. For example, the accommodating body 11323 is a shell-like structure, and the shell is surrounded to form the accommodating body 11323. Then the connecting hole 11321 is opened on the shell wall of the shell and passes through the shell wall of the shell.

[0127] The connecting hole 11321 connects the space of the drying chamber 11324 of the accommodating body 11323 with the space outside the accommodating body 11323, so that the gas in the external space can be exchanged with the gas in the drying chamber 11324. When the dehumidification device 1130 is installed on the box 1110 of the battery 1100, the gas in the drying chamber 11324 can be exchanged with the accommodating space 1113 inside the box 1110 through the connecting hole 11321, and the gas carrying moisture in the accommodating space 1113 can enter the drying chamber 11324 through the connecting hole 11321. The gas carrying moisture in the drying chamber 11324 is dried by the desiccant, and the dried gas enters the accommodating space 1113 through the connecting hole 11321, thereby achieving the purpose of drying the accommodating space 1113 inside the battery 1100.

[0128] There may be one or more connecting holes 11321 , and the multiple connecting holes 11321 can increase the volume and efficiency of gas exchange, thereby improving the efficiency of the drying component 1132 in drying the interior of the battery 1100 .

[0129] In this example, the connecting hole 11321 is used to exchange flow between the space of the drying chamber 11324 and the space outside the accommodating body 11323, so that moisture or water in the external space can enter the drying chamber 11324, and the gas dried by the desiccant can re-enter the external space through the connecting hole 11321, thereby achieving the purpose of drying through flow exchange. Multiple connecting holes 11321 can improve the efficiency of drying.

[0130] In some examples, reference Figure 7-9 As shown, the drying component 1132 also includes an air guide component 11325, on which is formed at least one air guide channel 113253, which connects the space inside the drying chamber 11324 and the space outside the drying chamber 11324; the air guide component 11325 is connected to the accommodating body 11323 and is disposed in the drying chamber 11324.

[0131] Specifically, the air guide component 11325 is arranged in the drying chamber 11324, so it can be known that the air guide component 11325 will be wrapped with desiccant in its circumference; an air guide channel 113253 is opened on the air guide component 11325, and the air guide channel 113253 connects the internal space of the drying chamber 11324 with the external space of the drying chamber 11324, so it can be known that the gas carrying moisture in the external space of the drying chamber 11324 can enter the internal space of the drying chamber 11324 through the air guide channel 113253, and the desiccant is located outside the air guide component 11325, so the desiccant absorbs moisture to form dry gas, and the dry gas then flows to the space outside the drying chamber 11324 through the air guide channel 113253, so it can be known that the setting of the air guide component 11325 can increase the exchange area and exchange efficiency between the dehumidification device 1130 and the outside, thereby improving the drying efficiency of the dehumidification device 1130.

[0132] Considering that the desiccant at the center of the drying chamber 11324 is wrapped by the surrounding desiccant, the desiccant at the center is not easy to absorb moisture, the water content in the desiccant is uneven, and the desiccant at the center cannot be fully utilized. Therefore, the air guide component 11325 is arranged in the drying chamber 11324. For example, the air guide component 11325 can be located at the center of the drying chamber 11324, so that the desiccant at the center of the drying chamber 11324 can directly exchange flow with the external moisture-carrying gas through the air guide channel 113253, thereby improving the utilization efficiency of the desiccant and improving the efficiency of dehumidification and drying.

[0133] In this example, by providing an air guide component 11325 with an air guide channel 113253, the exchange area and exchange efficiency between the desiccant in the drying chamber 11324 and the external space can be increased, thereby improving the drying efficiency of the dehumidification device 1130.

[0134] In some examples, reference Figure 7-9 As shown, the air guide channel 113253 has an air guide inlet 113251 and an air guide outlet 113252, the air guide component 11325 is cylindrical, the cylinder cavity of the air guide component 11325 forms the air guide channel 113253, the air guide inlet 113251 is opened on the cavity wall of the cylinder cavity, the cylinder end of the air guide component 11325 is connected to the accommodating body 11323, and the air guide outlet 113252 is opened on the cylinder end of the air guide component 11325.

[0135] Specifically, the air guide channel 113253 can connect the internal space of the drying chamber 11324 with the external space of the drying chamber 11324. Therefore, it can be known that the air guide channel 113253 has an air guide inlet 113251 and an air guide outlet 113252. The air guide component 11325 is cylindrical, and the air guide component 11325 extends along its own central axis and extends to form two cylinder ends. One cylinder end of the air guide component 11325 is connected to the accommodating body 11323, and the air guide outlet 113252 is opened on the cylinder end, so that the air guide outlet 113252 is connected to the accommodating body 11323. 323 is connected; the barrel cavity of the air-guiding component 11325 forms an air-guiding channel 113253, and the air-guiding component 11325 is arranged in the drying chamber 11324, then an air-guiding inlet 113251 is opened on the barrel wall of the air-guiding component 11325, and the air-guiding inlet 113251 is a through-hole structure opened on the barrel cavity wall, and a plurality of air-guiding inlets 113251 can be opened, and the plurality of air-guiding inlets 113251 are arranged at intervals on the barrel cavity wall of the air-guiding component 11325, so that the air-guiding channel 113253 is connected with the drying chamber 11324 through the air-guiding inlet 113251.

[0136] The air guide component 11325 is cylindrical, and the outer contour of the cross section of the air guide component 11325 can be circular, elliptical, polygonal, etc. The air guide component 11325 can be set at the center of the drying chamber 11324 or close to the center.

[0137] In this example, the air guide component 11325 is cylindrical and connected to the accommodating body 11323 at the end of the cylinder, so that the air guide component 11325 forms an outwardly convex plug-in state in the drying chamber 11324, so that the air guide component 11325 can be inserted into the interior of the desiccant, thereby increasing the exchange area and exchange efficiency between the interior of the desiccant and the external space of the drying chamber 11324, thereby improving the dehumidification and drying efficiency.

[0138] In some examples, reference Figure 7 and Fig.10 As shown, a first connection structure 113222 is formed on the mounting seat 11322 , a second connection structure 113231 is formed on the accommodating body 11323 , and the first connection structure 113222 is threadedly connected to the second connection structure 113231 .

[0139] Specifically, the first connecting structure 113222 can be an internal thread structure, and a mounting hole 113221 is opened on the mounting seat 11322, and an internal thread structure is formed on the hole wall of the mounting hole 113221; correspondingly, the second connecting structure 113231 is an external thread structure, and an external thread structure is formed on the outer surface of the accommodating body 11323. For example, the accommodating body 11323 is cylindrical, and the external thread structure is formed on the outer cylinder wall of the cylinder end, so that the external thread structure of the accommodating body 11323 is threadedly matched with the internal thread structure of the mounting seat 11322, thereby achieving the purpose of connecting and disassembling the accommodating body 11323 and the mounting seat 11322.

[0140] Optionally, the first connecting structure 113222 can be an external thread structure, and a protrusion that protrudes and extends toward the accommodating body 11323 is formed on the mounting seat 11322, and the external thread structure is formed on the outer peripheral surface of the protrusion; correspondingly, the second connecting structure 113231 is an internal thread structure, and an external thread structure is formed on the inner surface of the accommodating body 11323. For example, the accommodating body 11323 is cylindrical, and the cylindrical cavity forms a drying cavity 11324. The internal thread structure is formed on the cavity wall of the drying cavity 11324 near one end of the mounting seat 11322, so that the internal thread structure of the accommodating body 11323 is threadedly matched with the external thread structure of the mounting seat 11322, thereby achieving the purpose of connecting and disassembling the accommodating body 11323 and the mounting seat 11322.

[0141] In this example, a threaded connection is adopted between the mounting seat 11322 and the accommodating body 11323. The threaded structure is easy to manufacture and can make the installation and disassembly between the mounting seat 11322 and the accommodating body 11323 more convenient.

[0142] In some examples, reference Fig.11 and Fig.12 As shown, the dehumidification device 1130 also includes a first locking structure 1135, a second locking structure 1136 and a first detection structure (not shown in the figure), the first locking structure 1135 is connected to the light guide component 1131, the second locking structure 1136 is connected to the drying component 1132, the first locking structure 1135 is connected to the second locking structure 1136 to be in a locked state, the first locking structure 1135 is disengaged from the second locking structure 1136 to be in an unlocked state, and the first detection structure is connected between the first locking structure 1135 and the second locking structure 1136 to detect whether the first locking structure 1135 and the second locking structure 1136 are in a locked state or an unlocked state.

[0143] Specifically, the first locking structure 1135 and the second locking structure 1136 can be connected by means of plug-in, magnetic attraction, etc.; the first detection structure includes a first detection module and a first prompt module, and the first detection module may include detection structures such as position sensors and pressure sensors. The first detection module collects the connection relationship between the first locking structure 1135 and the second locking structure 1136, for example, position or pressure, etc., and then transmits the position information or pressure information to the first prompt module. The first prompt module can issue a prompt or warning information indicating the connection relationship between the first locking structure 1135 and the second locking structure 1136 by sound, light, etc.

[0144] For example, the first locking structure 1135 is connected to the second locking structure 1136, and the two are in a first locking state, then the light guide component 1131 and the drying component 1132 are assembled. At this time, the first detection structure detects the locking information and can issue a voice prompt to prompt that the light guide component 1131 and the drying component 1132 are connected. For another example, the first locking structure 1135 and the second locking structure 1136 are disengaged, and the two are in a first unlocking state. At this time, the first detection structure fails to detect the locking information and also issues a voice prompt or an alarm to prompt that the light guide component 1131 and the drying component 1132 are not connected in place or are accidentally disengaged.

[0145] In this example, by setting the first locking structure 1135, the second locking structure 1136 and the first detection structure, a reliable connection is achieved between the light guide component 1131 and the drying component 1132. In the event that the light guide component 1131 and the drying component 1132 are accidentally detached or not connected in place, the first detection structure can detect the risk and prompt the operator, thereby improving the reliability of the dehumidification device 1130.

[0147] In some examples, reference Figure 2 and Figure 3 As shown, the present application also discloses an example of a battery 1100, the battery 1100 includes the dehumidification device 1130 in any of the above examples, the dehumidification device 1130 is used to dehumidify and dry the battery 1100, for example, to dry the accommodation space 1113 inside the battery 1100 for accommodating the battery cell 1120, similarly, the dehumidification device 1130 can also dehumidify and dry other spaces inside the battery 1100 or the external space of the battery 1100, etc.

[0148] The example of battery 1100 in the present application is based on the example of dehumidification device 1130 described above. The example of battery 1100 includes all technical effects of the example of dehumidification device 1130 described above, which will not be described in detail.

[0149] In some examples, reference Figure 2 and Figure 3 As shown, the battery 1100 includes a box body 1110 having an accommodating space 1113 , a dehumidifying device 1130 is connected to the box body 1110 , and a drying component 1132 is accommodated in the accommodating space 1113 .

[0150] Specifically, the box body 1110 may be a shell plate structure, so the first part 1111 and the second part 1112 may both be shell plate structures, and the first part 1111 may be a hollow structure with an opening, that is, an inner cavity is formed on the first part 1111, and an opening communicating with the inner cavity is formed, for example, the first part 1111 is a shell structure formed with a receiving groove. The second part 1112 may also be a hollow structure with an opening, and the second part 1112 is covered on the opening of the first part 1111 to enclose and form a receiving space 1113, and the battery cell 1120 or the battery 1100 module is contained in the receiving space 1113; or, the second part 1112 may be a plate structure, for example, the second part 1112 is a cover plate, and the cover plate is covered on the opening of the first part 1111 to enclose and form a receiving space 1113 with the first part 1111.

[0151] The accommodation space 1113 is used to accommodate the battery cell 1120. The battery cell 1120 includes an electrode assembly. The electrode assembly is one of the core components of the battery 1100. The electrode assembly can convert chemical energy into electrical energy. The basic structure of the electrode assembly includes a positive electrode sheet, a negative electrode sheet, a diaphragm, and a tab. The tab includes a positive tab connected to the positive electrode sheet and a negative tab connected to the negative electrode sheet. The positive electrode sheet and the negative electrode sheet are separated by a diaphragm. During the discharge process, the positive electrode sheet and the negative electrode sheet undergo an oxidation-reduction reaction to generate current.

[0152] There may be multiple dehumidification devices 1130, and the dehumidification devices 1130 may be connected to the first part 1111 or the second part 1112 of the box body 1110, or the first part 1111 and the second part 1112 may be respectively provided with dehumidification devices 1130, and the dehumidification devices 1130 are used to dry the accommodating space 1113, thereby achieving the purpose of drying the battery cells 1120 and the surrounding environment in which they are located. Therefore, the drying component 1132 needs to be located in the accommodating space 1113; the light guide component 1131 may be located in the accommodating space 1113, or may be located outside the accommodating space 1113, but the light guide entrance 11311 needs to be exposed to the outside of the box body 1110, so that the operator can observe the drying chamber 11324 through the light guide entrance 11311 outside the box body 1110.

[0153] A pairing hole is provided on the case 1110, the dehumidification device 1130 is plugged into the pairing hole, and the drying component 1132 can be inserted into the accommodating space 1113; when the dehumidification device 1130 is connected to the case 1110, the drying component 1132 can be connected to the case 1110, for example, the mounting seat 11322 or the accommodating body 11323 in the drying component 1132 is connected to the case 1110, or the light guide component 1131 can be connected to the case 1110, for example, the main body structure 11315 in the light guide component 1131 is connected to the case 1110; the dehumidification device 1130 and the case 1110 can be connected by interference fit, threaded connection, limited insertion, snap-on connection and the like; the connection position between the dehumidification device 1130 and the case 1110 needs to be sealed so that the accommodating space 1113 is isolated from the space outside the battery 1100.

[0154] In this example, the dehumidification device 1130 is assembled with the box 1110 of the battery 1100, and the drying component 1132 is accommodated in the accommodating space 1113, so that the dehumidification device 1130 can dehumidify and dry the inside of the battery 1100, thereby improving the reliability of the battery 1100 during use.

[0155] In some examples, reference Figure 2 and Figure 3 As shown, the battery 1100 further includes a locking assembly (not shown), which is connected between the dehumidification device 1130 and the box body 1110 .

[0156] Specifically, when the dehumidifier 1130 is connected to the housing 1110 , the dehumidifier 1130 can be locked on the housing 1110 by providing a locking assembly, thereby facilitating improving the reliability of the connection between the dehumidifier 1130 and the housing 1110 .

[0157] The locking component can adopt a bolt component, for example, a screw, and threaded holes are opened at corresponding positions of the mounting seat 11322 and the box body 1110, so that the locking component is connected between the mounting seat 11322 of the dehumidification device 1130 and the box body 1110, thereby achieving the purpose of fixing the dehumidification device 1130.

[0158] In this example, the dehumidification device 1130 is connected to the box body 1110 through a locking assembly, thereby realizing a detachable connection between the dehumidification device 1130 and the box body 1110, making the installation and removal of the dehumidification device 1130 and the box body 1110 more convenient.

[0159] In some examples, reference Figure 2 As shown, the battery 1100 also includes a sealing assembly 1137 , which is connected between the dehumidification device 1130 and the box body 1110 .

[0160] In this example, the sealing assembly 1137 may include a sealing ring, which may be elastic and may be made of silicone, rubber or other materials. The sealing ring is connected between the connecting surface of the mounting seat 11322 and the box body 1110, or the sealing ring is arranged at a position where the pairing hole of the box body 1110 contacts the surface of the mounting seat 11322, thereby improving the sealing between the connecting position of the dehumidification device 1130 and the box body 1110.

[0161] In some examples, reference Figure 2 and Fig.13 As shown, the battery 1100 also includes a third locking structure 1140, a fourth locking structure 1150 and a second detection structure (not shown in the figure), the third locking structure 1140 is connected to the dehumidification device 1130, the fourth locking structure 1150 is connected to the box body 1110, the third locking structure 1140 and the fourth locking structure 1150 are connected to be in a second locked state, the third locking structure 1140 and the fourth locking structure 1150 are disengaged to be in a second unlocked state, and the second detection structure is connected between the third locking structure 1140 and the fourth locking structure 1150 to detect whether the third locking structure 1140 and the fourth locking structure 1150 are in the second locked state or the second unlocked state.

[0162] Specifically, the third locking structure 1140 and the fourth locking structure 1150 can be connected by plugging, magnetic attraction, etc.; the second detection structure includes a second detection module and a second prompt module, and the second detection module may include detection structures such as position sensors and pressure sensors. The second detection module collects the connection relationship between the third locking structure 1140 and the fourth locking structure 1150, for example, position or pressure, etc., and then transmits the position information or pressure information to the second prompt module. The second prompt module can issue a prompt or warning information indicating the connection relationship between the third locking structure 1140 and the fourth locking structure 1150 by sound, light, etc.

[0163] For example, the third locking structure 1140 is connected to the fourth locking structure 1150, and the two are in the third locking state, then the dehumidification device 1130 is assembled with the box body 1110. At this time, the second detection structure detects the locking information and can issue a voice prompt to indicate that the dehumidification device 1130 is connected to the box body 1110. For another example, the third locking structure 1140 is disengaged from the fourth locking structure 1150, and the two are in the first unlocking state. At this time, the second detection structure fails to detect the locking information and also issues a voice prompt or alarm to indicate that the dehumidification device 1130 is not connected to the box body 1110 or is accidentally disengaged.

[0164] Among them, the third locking structure 1140 can be connected to the drying component 1132 or the light guide component 1131 of the dehumidification device 1130, for example, installed on the main body structure 11315 or the mounting seat 11322 or the containing body 11323, so that when the separate main body structure 11315 or the mounting seat 11322 or the containing body 11323 is separated from the box 1110, the second detection structure can detect and prompt, alarm, etc.

[0165] The second detection structure can also be connected to the BMS system of the vehicle 1000. The BMS (Battery Management System) of the vehicle 1000 is an electronic control unit (ECU) in the vehicle 1000, which is responsible for monitoring and managing the operation of the battery 1100 used in the electric vehicle. By connecting the second detection structure to the BMS system, the operation of the battery 1100 of the vehicle 1000 and the operation of the vehicle 1000 are controlled. For example, when the second detection structure does not detect the locking information that the third locking structure 1140 and the fourth locking structure 1150 are in the second locking state, the second detection structure transmits the information to the BMS system, so that the BMS system cannot start the battery 1100 to supply power, thereby failing to start the vehicle 1000.

[0166] In this example, by setting a third locking structure 1140, a fourth locking structure 1150 and a second detection structure, a reliable connection between the dehumidification device 1130 and the box body 1110 is achieved. In the event that the dehumidification device 1130 and the box body 1110 are accidentally detached or not properly connected, the second detection structure can detect the risk and prompt the operator, thereby improving the reliability of the connection between the dehumidification device 1130 and the box body 1110.
