Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] The following is for reference. Figures 1 to 5 This application describes a battery housing and a vehicle according to embodiments thereof.

[0023] Please see Figure 1 , Figure 2 and Figure 3This application provides a battery housing 10, including a housing 1, a cover 2, a movable part 3, a reset part 4, and a plug-in part 5.

[0024] The housing 1 has a base plate (not shown) and an outer frame 11 connected to the base plate. A cover 2 is connected to the side of the outer frame 11 opposite to the base plate, forming a receiving cavity together with the outer frame 11 and the base plate. A movable member 3 is installed on the side of the cover 2 and is movably disposed between an unlocked position and a locked position along the side of the cover 2. A reset member 4 is installed inside the cover 2 and connected to the movable member 3, providing a reset force to move the movable member 3 to the locked position. A connector 5 is fixedly connected to the movable member 3, and the outer side wall of the outer frame 11 has a connector hole 111 perpendicular to this outer side wall. When the movable member 3 moves to the locked position, the connector 5 engages with the connector hole 111; when the movable member 3 moves to the unlocked position, the connector 5 disengages from the connector hole 111.

[0025] The housing 1 serves as the main load-bearing structure of the battery housing 10, housing internal components such as battery cells, wiring harnesses, and the battery 100 management system. The base plate and the outer frame 11 can be fixedly connected, for example, by welding, riveting, or integral casting to form an integral housing 1 structure. The outer frame 11 is arranged around the edge of the base plate, with an opening 22 on the side facing away from the base plate for mounting the cover 2. The receiving cavity is used to accommodate the battery 100 module and related electrical components, and can be sealed and protected by the cover 2.

[0026] The cover 2 is used to close the opening 22 of the housing 1 to protect the battery cells and electrical components inside the housing from external mud, dust and gravel impacts. The cover 2 is connected to the top of the outer frame 11, and its periphery fits against the upper surface of the outer frame 11. It can be sealed with a gasket to meet the IP67 protection level requirements.

[0027] The movable component 3 is installed on the side of the cover 2, serving as an intermediate transmission component for driving the plug-in component 5. The movable component 3 is movably arranged along the side of the cover 2. Here, "sideways" refers to the direction within the plane where the cover 2 is located, that is, the width or length direction of the cover 2, which is also the transverse or longitudinal direction of the vehicle 1000 coordinate system, depending on which side of the cover 2 the movable component 3 is installed on.

[0028] The movable component 3 reciprocates between the unlocked and locked positions to control the insertion and engagement state of the connector 5 and the outer frame 11. In some embodiments, the movable component 3 can be a slider that is slidably mounted on the side edge of the cover 2; in other embodiments, the movable component 3 can also be a lever or a dial, which switches positions by rotation or sliding; in still other embodiments, the movable component 3 can also be a rotating claw, which switches between the locked and unlocked positions by rotation.

[0029] The number of movable parts 3 is not specifically limited in this application; there may be one, two, three, four, or more. When there are two movable parts 3, the two movable parts 3 can be respectively set on two opposite sides of the cover 2, such as the left and right sides, to achieve synchronous locking on both sides and improve connection stability. When there are four movable parts 3, the four movable parts 3 can be respectively set on the four sides of the cover 2 to achieve synchronous locking on all four sides.

[0030] The connector 5 is fixedly connected to the movable part 3 and is used to form a plug-in engagement with the plug hole 111 provided on the outer side wall of the outer frame 11, thereby realizing the detachable locking between the cover 2 and the outer frame 11. The plug hole 111 is opened perpendicular to the outer side wall of the outer frame 11, that is, the axial direction of the plug hole 111 is consistent with the normal direction of the outer side wall of the outer frame 11. In some embodiments, the connector 5 can be a pin or a latch, the shape of which is adapted to the shape of the plug hole 111.

[0031] The fixed connection between the connector 5 and the movable part 3 can be implemented in various ways: in some examples, the connector 5 can be integrally formed with the movable part 3, for example, by injection molding or die casting to form an integral part; in other examples, the connector 5 can be fixedly connected to the movable part 3 by threaded fasteners; in still other examples, the connector 5 can be fixedly connected to the movable part 3 by welding or bonding. When the movable part 3 moves laterally along the cover 2 to the locked position, the connector 5 moves synchronously with the movable part 3, and its end extends into the insertion hole 111 on the outer wall of the outer frame 11 to form a plug-in fit, thereby locking the cover 2 onto the box 1 and preventing the cover 2 from detaching from the outer frame 11 when subjected to vibration or impact. When the movable part 3 moves laterally along the cover 2 to the unlocked position, the connector 5 moves in the opposite direction with the movable part 3, and its end disengages from the insertion hole 111, releasing the plug-in fit. At this time, the lock between the cover 2 and the outer frame 11 is released, and the cover 2 can be removed.

[0032] The reset element 4 is installed inside the cover 2 and connected to the movable element 3, providing a reset force for the movable element 3 to move toward the locked position. When the cover 2 is installed on the housing 1, the connector 5 remains inserted into the connector hole 111 under the action of the reset element 4, thereby ensuring the reliability of the lock and preventing the connector 5 from accidentally dislodging due to vibration during vehicle 1000 operation. In some embodiments, the reset element 4 can be a compression spring, with one end abutting against the cover 2 and the other end abutting against the movable element 3, pushing the movable element 3 toward the locked position through the compression force of the spring. In other embodiments, the reset element 4 can also be a tension spring, with both ends connected to the cover 2 and the movable element 3 respectively, pulling the movable element 3 toward the locked position through the tension force of the spring. In still other embodiments, the reset element 4 can also be a torsion spring, driving the movable element 3 to rotate toward the locked position through the torsional force of the torsion spring.

[0033] The connection method between the reset component 4 and the movable component 3 should ensure the reliable transmission of the reset force: In some examples, the movable component 3 is provided with a spring mounting post, and the reset component 4 is sleeved on the spring mounting post; in other examples, the movable component 3 is provided with a hook, and the reset component 4 is hooked to the hook; in still other examples, one end of the reset component 4 can be directly welded or glued to the movable component 3.

[0034] In actual operation, when the cover 2 needs to be installed onto the housing 1, the operator first applies force to the movable part 3 to overcome the reset force of the reset part 4, causing the movable part 3 to move laterally along the cover 2 to the unlocked position. The cover 2 is then placed at the opening 22 end of the outer frame 11, ensuring the periphery of the cover 2 aligns with the upper surface of the outer frame 11. The movable part 3 is then released, and under the reset force provided by the reset part 4, it moves laterally along the cover 2 to the locked position. The connector 5 moves with the movable part 3 and inserts into the connector hole 111 on the outer wall of the outer frame 11, achieving a locking fit and completing the locking installation of the cover 2. When the cover 2 needs to be removed, force is applied to the movable part 3 again to overcome the reset force and move it to the unlocked position. The connector 5 then disengages from the connector hole 111, allowing the cover 2 to be removed from the housing 1. The entire process is simple and requires no tools for quick installation and removal of the cover 2.

[0035] According to the battery box 10 provided in the embodiments of this application, by setting a movable movable part 3, a reset part 4 that provides a reset force, and a plug part 5 that is fixedly connected to the movable part 3, and in conjunction with the plug hole 111 on the outer side wall of the outer frame 11, the quick locking and unlocking between the cover 2 and the box 1 is realized. While ensuring connection stability and impact resistance, the convenience of installation and disassembly is significantly improved.

[0036] Please see Figure 3 According to some embodiments of this application, the battery housing 10 further includes a sealing member 6. The sealing member 6 is disposed within the receiving cavity and seals the gap between the cover 2 and the outer frame 11. At least a portion of the sealing member 6 is connected to the inner sidewall of the outer frame 11. A insertion hole 111 penetrates the outer frame 11. A sealing groove 61 corresponding to the insertion hole 111 is provided on the side of the sealing member 6 facing the outer frame 11. At least a portion of the insertion member 5 passes through the insertion hole 111 and extends into the sealing groove 61.

[0037] The sealing element 6 is used to seal the cover 2 and the outer frame 11, preventing external mud, water, and dust from entering the cavity through the gap at the joint surface between the cover 2 and the outer frame 11, thereby ensuring the sealing and protective performance of the battery box 10. The sealing element 6 is located inside the cavity, specifically between the edge of the cover 2 and the upper end face of the outer frame 11. When the cover 2 is closed on the outer frame 11, the cover 2 presses against the sealing element 6, causing the sealing element 6 to undergo elastic deformation, thereby filling the tiny gap between the cavity and the cover 2.

[0038] At least a portion of the seal 6 is connected to the inner wall of the outer frame 11, that is, the main body of the seal 6 is disposed on the inner wall surface of the outer frame 11 and extends along the inner wall, so that the seal 6 can maintain a stable position when squeezed by the cover 2, and prevent the seal 6 from shifting or falling off during assembly.

[0039] In some embodiments, the seal 6 can be an annular sealing ring that extends continuously along the inner sidewall of the outer frame 11 to achieve a circumferentially fully enclosed seal. The seal 6 can be made of an oil-resistant and high-temperature-resistant elastic material, such as rubber, silicone, or foam sealing material, to ensure the long-term stability of the sealing performance under long-term use of the vehicle 1000 and temperature variation environments.

[0040] There are several ways to connect the seal 6 to the inner wall of the outer frame 11. In some examples, the seal 6 can be fixed to the inner wall of the outer frame 11 by adhesive bonding, such as using structural adhesive or double-sided tape to attach the seal 6 to the surface of the inner wall. In other examples, the inner wall of the outer frame 11 can be provided with a positioning groove, and at least a portion of the seal 6 is embedded in the positioning groove, with the positioning and fixing of the seal 6 achieved by the clamping force of the groove wall. In still other examples, the seal 6 can be connected to the inner wall of the outer frame 11 by snap-fit, for example, the seal 6 is provided with a hook, and the inner wall of the outer frame 11 is provided with a corresponding slot, with the hook snapping into the slot for fixing.

[0041] The insertion hole 111 extends through the outer frame 11, meaning it extends from the outer sidewall surface of the outer frame 11 to the inner sidewall surface, forming a through-hole structure. With the insertion hole 111 penetrating the outer frame 11, the connector 5, in the locked position, can pass through the entire sidewall of the outer frame 11 from the outside and extend into the receiving cavity, thereby increasing the insertion depth between the connector 5 and the outer frame 11 and improving the stability of the lock.

[0042] The sealing element 6 has a sealing groove 61 corresponding to the insertion hole 111 on the side facing the outer frame 11. The sealing groove 61 is provided on the surface of the sealing element 6 facing the side wall of the outer frame 11, that is, the sealing element 6 has a recessed groove structure at the position where the insertion hole 111 passes through the inner side wall of the outer frame 11. The sealing groove 61 corresponds to the position of the insertion hole 111. That is, when the sealing element 6 is installed on the inner side wall of the outer frame 11 according to the preset position, the opening 22 of the sealing groove 61 is directly opposite the opening of the insertion hole 111 at one end of the inner side wall of the outer frame 11, so that the insertion element 5 can directly extend into the sealing groove 61 after passing through the insertion hole 111. The size of the sealing groove 61 is adapted to the end size of the insertion element 5, and the depth of the sealing groove 61 is not less than the length of the insertion element 5 extending into the sealing groove 61. By setting the sealing groove 61, the end of the plug 5 extends into the sealing groove 61 when it is in the locked position, without piercing or penetrating the seal 6. This achieves both the plug-in locking function and ensures the integrity and continuity of the seal 6, avoiding the sealing failure problem caused by opening a through hole in the seal 6.

[0043] When the movable part 3 is in the locked position, the connector 5 passes through the connector hole 111, at least partially protruding from the inner wall of the outer frame 11, and extends into the sealing groove 61 provided on the side of the seal 6 facing the outer frame 11, achieving a locking fit between the cover 2 and the outer frame 11. At this time, the end of the connector 5 is wrapped by the sealing groove 61, and the seal 6 forms a continuous and complete sealing barrier between the cover 2 and the outer frame 11. When the movable part 3 is in the unlocked position, the connector 5 exits from the sealing groove 61 and moves in the opposite direction with the movable part 3, passing through the connector hole 111 and retracting to the side of the cover 2, thus releasing the lock.

[0044] By providing a sealing element 6 to seal the gap between the sealing cover 2 and the outer frame 11 within the receiving cavity, and allowing the insertion hole 111 to penetrate the outer frame 11, while simultaneously opening a sealing groove 61 corresponding to the insertion hole 111 on the side of the sealing element 6 facing the outer frame 11, allowing the insertion part 5 to pass through the insertion hole 111 and extend in, the continuous integrity of the sealing element 6 is maintained while ensuring the locking function. This avoids the sealing performance degradation caused by the insertion part 5 puncturing the sealing element 6, enabling the battery box 10 to reliably maintain its sealing protection level even under conditions of frequent disassembly and reassembly of the cover 2.

[0045] Please see Figure 3 According to some embodiments of this application, the battery housing 10 may further include a connector 7. The connector 7 is located on the side of the cover 2 facing the outer frame 11 and is fixedly connected to the movable member 3. A plug-in member 5 is installed on the side of the connector 7 facing the outer frame 11. When the movable member 3 is in the locked position, the connector 7 abuts against the outer side wall of the outer frame 11.

[0046] The connector 7 is used to realize the power transmission and connection transition between the movable part 3 and the plug-in part 5. The connector 7 is located on the side of the cover 2 facing the outer frame 11, that is, the connector 7 is located on the lower surface of the cover 2, which faces the upper end face of the outer frame 11 when the cover 2 is closed on the box 1. The connector 7 is fixedly connected to the movable part 3, which is installed on the side of the cover 2, while the connector 7 is located in the lower surface side edge area of ​​the cover 2. The two can be connected through a through groove or notch opened on the side of the cover 2.

[0047] In some embodiments, the movable part 3 and the connecting part 7 can be integrally formed, for example, by injection molding or die casting to form a single component, in order to improve structural strength and transmission accuracy; in other embodiments, the movable part 3 and the connecting part 7 can be separate structures and are fixedly connected by threaded fasteners, for example, by using screws to pass through the through holes on the movable part 3 and then screw them into the threaded holes on the connecting part 7; in still other embodiments, the movable part 3 and the connecting part 7 can be fixedly connected by welding or riveting.

[0048] The connector 7 allows the movement of the movable part 3 to be reliably transmitted to the plug 5. At the same time, since the connector 7 is located on the lower surface of the cover 2, it does not occupy the space on the upper surface of the cover 2, which helps to keep the cover 2 clean.

[0049] The connector 5, which directly engages with the insertion hole 111 on the outer frame 11, is located on the side of the connector 7 facing the outer frame 11, i.e., the side surface of the connector 7 facing the outer wall of the outer frame 11. When the movable member 3 is in the locked position, the connector 5 moves with the movable member 3 and the connector 7 until its end extends into the insertion hole 111, thereby locking the connector.

[0050] There are several ways to mount the connector 5 onto the connector 7. In some examples, the connector 5 can be integrally formed with the connector 7, for example, the connector 5 can be an integrally protruding columnar structure on the connector 7, and the two can be formed as one piece by machining or casting. In other examples, the connector 5 can be mounted onto the connector 7 by a threaded connection, for example, the connector 7 has a threaded mounting hole, one end of the connector 5 has an external thread, and the connector 5 and the connector 7 are screwed together and fixed. In still other examples, the connector 5 can be mounted onto the connector 7 by an interference fit or a snap-fit. When the connector 5 and the connector 7 adopt a separate mounting structure, it is convenient to replace the connector 5 separately after it wears out, reducing maintenance costs.

[0051] The number of connectors 7 is not specifically limited in this application, but corresponds to the number of movable parts 3. When there is one movable part 3, there is one corresponding connector 7; when there are two movable parts 3, there are two corresponding connectors 7, with the two connectors 7 respectively located at two opposite side edges of the cover 2. In embodiments with multiple connectors 7, each connector 7 can be arranged at intervals around the edge of the cover 2, and each connector 7 is provided with a corresponding plug 5 to achieve multi-point locking of the cover 2, further improving the connection stability between the cover 2 and the housing 1.

[0052] When the movable part 3 is in the locked position, the connecting part 7 abuts against the outer wall of the outer frame 11. This abutment refers to the contact between the outer surface of the connecting part 7 facing the cover 2 and the outer wall surface of the outer frame 11. Through the abutment between the connecting part 7 and the outer wall of the outer frame 11, the movement of the movable part 3 and the connecting part 7 is limited in the locked position. When the movable part 3 moves to the locked position under the reset force of the reset part 4, the connecting part 7 moves synchronously with it. When the connecting part 7 moves to the point where its surface contacts the outer wall of the outer frame 11, it is blocked by the outer wall and cannot continue moving. At this point, the movable part 3 reaches the locked position, and the insert 5 is fully inserted into the insert hole 111. Thus, the contact between the connector 7 and the outer side wall of the outer frame 11 achieves precise positioning of the locking position, ensuring that the mating depth of the connector 5 and the insertion hole 111 is consistent after each locking operation, and avoiding damage caused by the excessive pushing of the reset component 4, which would result in the connector 5 impacting the bottom of the insertion hole 111.

[0053] Meanwhile, when the vehicle 1000 vibrates during operation, the connecting piece 7 and the outer wall of the outer frame 11 are in contact, and the contact surface can bear part of the vibration impact force, reducing the impact load transmitted to the mating surface of the plug 5 and the plug hole 111, and further improving the stability and durability of the lock; the contact between the connecting piece 7 and the outer wall of the outer frame 11 also plays a certain role in sealing and protecting the outer end of the plug hole 111, further improving the sealing performance and durability.

[0054] Please see Figure 3 and Figure 4 According to some embodiments of this application, the side of the cover 2 may be provided with a movable groove 21, and the movable member 3 and the reset member 4 may be movably installed in the movable groove 21. The side wall of the cover 2 may be provided with an opening 22 communicating with the movable groove 21. The battery box 10 may also include an operating member 8, which may be connected to the movable member 3. The operating member 8 may be moved under the drive of an external force to move the movable member 3 between an unlocked position and a locked position. When the movable member 3 moves to the unlocked position, the operating member 8 moves out of the opening 22; when the movable member 3 moves to the locked position, the operating member 8 seals the opening 22.

[0055] A movable groove 21 is located on the side of the cover 2, providing installation space and motion guidance for the movable component 3 and the resetting component 4. The movable groove 21 is located inside the side of the cover 2, extending laterally, and its inner contour matches the outer contour of the movable component 3, allowing the movable component 3 to slide smoothly within the movable groove 21 in a predetermined direction. The movable groove 21 can be machined inside the side of the cover 2, such as by milling or drilling; or it can be cast together with the cover 2 during the casting process.

[0056] The interior of the movable groove 21 may be equipped with a guide structure, such as a guide rib at the bottom of the groove 21 and a guide groove at the corresponding position of the movable part 3. The movable part 3 is guided to move in a straight line by the cooperation of the rib and the groove, preventing the movable part 3 from deflecting or getting stuck in the movable groove 21. In embodiments with multiple movable parts 3, the number of movable grooves 21 corresponds to the number of movable parts 3. When there are two movable parts 3, each of the two opposite sides of the cover 2 is provided with a movable groove 21, and the two movable parts 3 are installed in the corresponding movable grooves 21. When there are four movable parts 3, each of the four sides of the cover 2 is provided with a movable groove 21. The cross-sectional shape of the movable groove 21 can be rectangular, circular, trapezoidal, or other regular shapes, specifically determined according to the shape of the movable part 3.

[0057] The side wall of the cover 2 has an opening 22 that communicates with the movable groove 21. The opening 22 is located on the surface of the side wall of the cover 2 facing the outside of the cover 2. The opening 22 connects the movable groove 21 to the outside of the cover 2, so that the operating member 8 can extend from the movable groove 21 to the outside of the cover 2 for the operator to apply force to operate. The shape of the opening 22 is adapted to the cross-sectional shape of the operating member 8. The size of the opening 22 should ensure that the operating member 8 can be fully extended out of the opening 22 when the movable member 3 is in the unlocked position, and leave sufficient operating space for the operator to pinch or flick it with their fingers.

[0058] The operating component 8 is used by the operator to apply force to drive the movable component 3 between the unlocked and locked positions. The operating component 8 is connected to the movable component 3; when the operating component 8 is subjected to external force, it drives the movable component 3 to move synchronously. The connection between the operating component 8 and the movable component 3 can be implemented in various ways. In some examples, the operating component 8 can be integrally formed with the movable component 3; for example, the end of the movable component 3 extends to the opening 22 and forms the operating component 8, allowing the operator to operate by directly pushing or pulling the end of the movable component 3. In other examples, the operating component 8 can be fixedly connected to the movable component 3 using threaded fasteners; for example, the operating component 8 is an independent button with a stud at its bottom, and the movable component 3 has a threaded hole, allowing the operating component 8 to be screwed and fixed together. In still other examples, the operating component 8 can be connected to the movable component 3 by a snap-fit ​​mechanism; for example, the operating component 8 has a buckle at its bottom, and the movable component 3 has a slot, allowing the buckle to snap into the slot for fixation.

[0059] The outer surface of the operating component 8 may be provided with an anti-slip structure, such as anti-slip ridges or anti-slip grooves, to increase the friction between the operator's fingers and the operating component 8, making it easier to apply force. The shape of the operating component 8 may be designed as a round-headed column, plate, ring, or hook, etc., which can be determined according to the operating space and usage habits.

[0060] In some embodiments, the operating member 8 may be provided with a handle 81.

[0061] Under the drive of an external force, the operating component 8 moves the movable component 3 between the unlocked and locked positions. When the operator applies a pulling force to the operating component 8 in the direction of the outside of the cover 2, the operating component 8 moves the movable component 3 from the locked position to the unlocked position; when the operator releases the external force on the operating component 8, the movable component 3 returns from the unlocked position to the locked position under the reset force of the reset component 4, simultaneously resetting the operating component 8. When the movable component 3 moves to the unlocked position, the operating component 8 moves with the movable component 3 to the outside of the opening 22. At this time, at least a portion of the operating component 8 extends to the outside of the side wall of the cover 2, allowing the operator to pinch or pull it for taking the cover 2 out of the unlocked state.

[0062] When the movable part 3 moves to the locked position, the operating part 8 resets with the movable part 3 and seals the opening 22. Sealing the opening 22 means that the outer surface of the operating part 8 is tightly fitted with the edge of the opening 22, completely sealing the opening 22. To achieve the sealing effect, the contour of the operating part 8 at the corresponding position of the opening 22 matches the contour of the opening 22. When the operating part 8 is in the locked position, it is embedded in the opening 22 and forms a sealing fit with the edge of the opening 22. In some embodiments, a sealing ring may be fitted around the outer periphery of the operating part 8. This sealing ring is pressed between the operating part 8 and the edge of the opening 22 when the operating part 8 is in the locked position, achieving a seal. In other embodiments, a sealing flange may be provided on the surface of the operating part 8 facing the edge of the opening 22. When the operating part 8 is in the locked position, the sealing flange abuts against the edge of the opening 22 and undergoes elastic deformation, thereby filling the gap between them. When the operating component 8 is in the locked position, the opening 22 is sealed, which can prevent external mud, water and dust from entering the movable groove 21 through the opening 22, avoid contaminating the movable component 3 and the reset component 4, and ensure the cleanliness of the internal environment of the movable groove 21, thereby ensuring the flexibility of the movable component 3 and the reliability of the reset component 4 in long-term use.

[0063] When the cover 2 needs to be removed, the operator pulls the operating component 8 outwards. The operating component 8 causes the movable component 3 to slide laterally to the unlocked position within the movable groove 21, overcoming the reset force of the reset component 4. The connector 5 moves synchronously with the movable component 3 and disengages from the connector hole 111. At this time, the operating component 8 moves to the outside of the opening 22 and remains extended. After the operator removes the cover 2 from the housing 1, the operating component 8 is released. The movable component 3 automatically slides back to the locked position under the reset force of the reset component 4. The connector 5 resets, and the operating component 8 resets with the movable component 3 and seals the opening 22, awaiting the next installation operation. When the cover 2 needs to be installed, the operator pulls the operating component 8 again, so that the movable component 3 is in the unlocked position. After placing the cover 2 on the outer frame 11 and aligning it, the operator releases the operating component 8. Under the reset force, the movable component 3 causes the connector 5 to insert into the connector hole 111, completing the locking. At the same time, the operating component 8 seals the opening 22 again.

[0064] By providing a stable installation and movement space for the movable component 3 and the reset component 4 through the movable slot 21, and by providing an opening 22 communicating with the movable slot 21 and an operating component 8 connected to the movable component 3, the operator can conveniently drive the movable component 3 from outside the cover 2 via the operating component 8, significantly improving the convenience of operation and human-machine interaction. Simultaneously, when the operating component 8 is in the locked position, it seals the opening 22, effectively preventing foreign objects from entering the movable slot 21, ensuring the long-term reliable operation of the movable component 3 and the reset component 4, and further improving the protection level and service life of the battery housing 10.

[0065] Please see Figure 3 and Figure 4 According to some embodiments of this application, the operating member 8 is provided with a magnetic suction member 82 and the opening 22 is provided with a magnetic suction part. When the movable member 3 is in the locked position, the magnetic suction member 82 and the magnetic suction part magnetically engage.

[0066] The magnetic chuck 82 can be disposed on the surface of the operating member 8 facing the edge of the opening 22, or it can be embedded inside the operating member 8, as long as the magnetic chuck 82 can correspond to the position of the magnetic suction part when the operating member 8 is in the locked position. There are various ways to fix the magnetic chuck 82 to the operating member 8. In some examples, the operating member 8 can have a mounting groove, and the magnetic chuck 82 is embedded in the mounting groove and fixed by interference fit or adhesive. In other examples, the magnetic chuck 82 can be integrally molded with the operating member 8 by in-mold injection molding. That is, the magnetic chuck 82 is pre-placed in the mold during injection molding of the operating member 8, and after injection molding, the magnetic chuck 82 is encapsulated and fixed inside the operating member 8. This method can effectively prevent the magnetic chuck 82 from falling off and avoid the magnetic chuck 82 from being directly exposed to the external environment and undergoing oxidation or corrosion. In still other examples, the magnetic chuck 82 can be fixed to the operating member 8 by threaded fasteners. The shape of the magnetic attractor 82 can be cylindrical, square, or ring-shaped, depending on the spatial structure of the operating component 8 and the opening 22.

[0067] The magnetic attractor 82 can be a permanent magnet, such as a neodymium magnet, ferrite magnet, or samarium cobalt magnet; or it can be a magnetically conductive material that can be attracted, such as an iron block or a steel block, as long as it forms a magnetic attraction with the magnetic component in the magnetic attractor.

[0068] The magnetic suction part is located at the opening 22. Specifically, the opening 22 can refer to the edge of the opening 22 or the wall of the movable groove 21 near the opening 22. In some embodiments, the magnetic suction part can be embedded in the edge sidewall of the opening 22, and when the operating member 8 is in the locked position, the magnetic suction part is directly opposite the magnetic suction element 82 on the operating member 8. In other embodiments, the magnetic suction part can be embedded in the wall of the movable groove 21 near the opening 22. When the operating member 8 is in the locked position, the end of the operating member 8 extends into the movable groove 21 a predetermined distance, at which point the magnetic suction element 82 and the magnetic suction part are opposite and attracted to each other inside the movable groove 21. The magnetic suction part and the structure at the opening 22 can be fixed by embedding, in-mold injection molding, or threaded connection.

[0069] The material of the magnetic suction part is compatible with that of the magnetic suction component 82. If the magnetic suction component 82 is a permanent magnet, the magnetic suction part can be a magnetic conductor; if the magnetic suction component 82 is a magnetic conductor, the magnetic suction part can be a permanent magnet; if the magnetic suction component 82 is a permanent magnet, the magnetic suction part can also be a permanent magnet. The two achieve adsorption and engagement through the attraction of opposite poles. The number of magnetic suction components 82 and magnetic suction parts is not specifically limited in this application; there can be one, two, three, or more of each. When there are two magnetic suction components 82 and two magnetic suction parts, the two magnetic suction components 82 can be respectively arranged on opposite sides of the operating component 8, and the two magnetic suction parts can be correspondingly arranged on opposite sides of the opening 22, making the adsorption force distribution more uniform and helping the operating component 8 to uniformly seal the opening 22.

[0070] When the movable part 3 moves towards the locked position under the reset force of the reset part 4, the operating part 8 moves synchronously with the movable part 3 and gradually approaches the edge of the opening 22. When the movable part 3 reaches the locked position, the operating part 8 is embedded in the opening 22. At this time, the magnetic suction part 82 is directly opposite the magnetic suction part and is closest to it. A magnetic attraction force is generated between the two, which pulls the operating part 8 towards the opening 22 and keeps the operating part 8 in the locked position.

[0071] As an auxiliary holding force, the magnetic attraction helps the reset member 4 maintain the operating member 8 and the movable member 3 in the locked position under the vibration and impact generated during the vehicle 1000's operation. This prevents the operating member 8 from accidentally moving in the unlocking direction due to severe vibration, which would cause the connector 5 to loosen from the connector hole 111, further improving the reliability of the lock. On the other hand, the magnetic attraction keeps the operating member 8 in close contact with the edge of the opening 22 when it is in the locked position, enhancing the sealing effect of the operating member 8 on the opening 22, which is beneficial to maintaining the airtightness of the internal environment of the movable groove 21 for a long time.

[0072] When unlocking is required, the operator applies external force to the operating component 8 to overcome the sum of the reset force of the reset component 4 and the magnetic attraction between the magnetic component 82 and the magnetic attraction part. The operating component 8 is pulled out of the opening 22, and the movable component 3 moves to the unlocked position. The plug 5 disengages from the plug hole 111, completing the unlocking operation. When relocking is required, the operator places the cover 2 on the outer frame 11 and releases the operating component 8. The movable component 3 moves to the locked position under the action of the reset component 4. When the operating component 8 moves close to the edge of the opening 22, the magnetic attraction between the magnetic component 82 and the magnetic attraction part automatically pulls the operating component 8 into the opening 22, assisting in completing the locking operation.

[0073] Please see Figure 3 According to some embodiments of this application, a guide member 9 is provided in the movable groove 21. The guide member 9 extends along the movable direction of the movable member 3, and the movable member 3 and the guide member 9 are guided and cooperated.

[0074] Guide member 9 is disposed within movable groove 21 to guide movable member 3 to slide along a preset direction within movable groove 21, preventing movable member 3 from deflecting, tilting, or jamming during movement. Guide member 9 extends along the movement direction of movable member 3, meaning the length direction of guide member 9 is consistent with the movement direction of movable member 3. The guiding engagement between movable member 3 and guide member 9 means that movable member 3 slides along the path defined by guide member 9 through contact and relative movement with guide member 9. Guide member 9 can be a guide rib formed on the inner wall of movable groove 21, an independent guide rod fixedly installed within movable groove 21, or a guide groove opened at the bottom of movable groove 21.

[0075] In some examples, the guide member 9 can be a guide rib, which protrudes from the bottom or wall of the movable groove 21 and extends along the direction of movement of the movable member 3. The movable member 3 has a corresponding guide groove, and the guide rib is embedded in the guide groove. The sliding cooperation between the rib and the groove guides the movable member 3 to move in a straight line, while limiting the deviation of the movable member 3 perpendicular to the direction of movement. In other examples, the guide member 9 can be a guide rod, with both ends fixed to two opposite walls of the movable groove 21. The movable member 3 has a guide hole, and the guide rod passes through the guide hole. The movable member 3 slides back and forth along the guide rod. This method provides more precise linear guidance, and the guide rod can be made of metal, possessing high wear resistance and bending strength, suitable for frequent operation conditions. In still other examples, the guide member 9 can be a guide groove formed at the bottom of the movable groove 21, extending along the direction of movement of the movable member 3. The movable member 3 has a corresponding guide block, which extends into and slides within the guide groove. The guide groove guides the movement of the movable member 3 by limiting the movement of the guide block.

[0076] The number of guide members 9 is not specifically limited in this application; there may be one, two, three, or more. When two guide members 9 are provided, the two guide members 9 can be respectively provided on opposite sides of the movable groove 21, such as the bottom and top of the groove, or the two sides of the groove wall. The movable member 3 is provided with two corresponding mating structures. The double-sided guidance further improves the smoothness and accuracy of the movement of the movable member 3 and effectively prevents the movable member 3 from rotating around the direction of movement during the sliding process.

[0077] The guide member 9 constrains and guides the movement of the movable member 3, ensuring that the movable member 3 always slides along a preset direction under the force of the reset member 4 and the driving force of the operating member 8. This prevents the connector 5 from failing to accurately align with the connector hole 111 due to the deflection of the movable member 3, or from increasing the operating resistance due to additional friction between the movable member 3 and the inner wall of the movable groove 21 caused by the tilting of the movable member 3. This ensures the smoothness of locking and unlocking operations and the alignment accuracy of the connector. At the same time, the guide member 9 also reduces the contact area between the movable member 3 and the inner wall of the movable groove 21, transforming surface contact into line contact or point contact, effectively reducing sliding friction resistance, making operation easier and less strenuous, and reducing wear between the movable member 3 and the movable groove 21, which helps to extend the service life.

[0078] Please see Figure 3 According to some embodiments of this application, multiple connectors 5 can be connected to the movable part 3, and the connector hole 111 is provided with multiple connectors corresponding to the multiple connectors 5.

[0079] Multiple connectors 5 are connected to the movable part 3 and move synchronously with the movement of the movable part 3. The number of connectors 5, which directly engage with the connector holes 111 on the outer frame 11, can be determined based on the size, weight, and required locking strength of the cover 2.

[0080] Multiple connectors 5 are disposed on the same movable member 3, that is, the movable member 3 extends a certain length along the side of the cover 2, and multiple connectors 5 are arranged at intervals within this length range. Each connector 5 is fixedly connected to the movable member 3. When the movable member 3 moves between the unlocked position and the locked position, all connectors 5 move synchronously with the movable member 3, so as to simultaneously insert into or simultaneously disengage from the corresponding connector hole 111.

[0081] The multiple connectors 5 on the movable member 3 can be arranged at equal intervals or at non-equal intervals. In some embodiments, the multiple connectors 5 can be arranged at equal intervals along the length of the movable member 3 so that the locking force is evenly distributed along the side of the cover 2.

[0082] Multiple connectors 5 can be provided in two, three, four, five or more, the specific number depending on the length of the side of the cover 2 and the required number of locking points. For example, when each side of the cover 2 is short, two connectors 5 can be provided, with the two connectors 5 respectively located near the two ends of the movable part 3, so as to form two locking points at the two ends of the side of the cover 2 to ensure the balance of locking; when the side of the cover 2 is long, three, four or more connectors 5 can be provided, arranged at intervals along the length of the movable part 3, to increase the number of locking points, making the connection between the cover 2 and the box 1 more stable, and avoiding local deformation or vibration of the cover 2 when subjected to impact due to the lack of locking points in the middle area of ​​the cover 2.

[0083] Each insertion hole 111 has multiple insertion holes corresponding to a plurality of insertion pieces 5. On the outer side wall of the outer frame 11, there is one insertion hole 111 corresponding to the position of each insertion piece 5. The number of insertion holes 111 is the same as the number of insertion pieces 5, and the position of each insertion hole 111 corresponds one-to-one with the position of each insertion piece 5. When the movable member 3 moves to the locked position, the plurality of insertion pieces 5 simultaneously insert into their respective insertion holes 111, forming a multi-point locking engagement. The arrangement of the plurality of insertion holes 111 on the outer side wall of the outer frame 11 is consistent with the arrangement of the plurality of insertion pieces 5 on the movable member 3, to ensure that each insertion piece 5 and its corresponding insertion hole 111 are accurately aligned in the locked position.

[0084] In some embodiments, the diameter and depth of multiple insertion holes 111 can be the same, so that the same type of connector 5 can be used for uniform mating, simplifying the manufacturing and assembly process. In other embodiments, the diameter and depth of insertion holes 111 at different locations can also be different depending on the stress conditions of each locking point. For example, the insertion hole 111 located at the corner of the cover 2 can have a larger depth to provide stronger pull-out resistance.

[0085] By connecting multiple connectors 5 to the same movable part 3 and setting a corresponding number of connector holes 111 on the outer frame 11, the operator only needs to operate one movable part 3 to simultaneously control the locking and unlocking of multiple connectors 5. This achieves high stability of multi-point locking while maintaining the convenience of single-point operation, avoiding the cumbersome disassembly and assembly problems caused by setting an operating structure for each locking point separately. Multi-point locking enables a more uniform distribution of the connection force between the cover 2 and the box 1, effectively preventing the cover 2 from deforming or failing to seal due to excessive local force during vehicle 1000 operation, further improving the structural integrity and sealing reliability of the battery box 10 under vibration and impact conditions.

[0086] According to some embodiments of this application, multiple movable parts 3 may be provided, and the multiple movable parts 3 are evenly distributed along the periphery of the cover 2; each movable part 3 is connected to a plug-in part 5 and a reset part 4.

[0087] There are multiple movable parts 3, that is, the number of movable parts 3 is two or more. The multiple movable parts 3 are evenly distributed along the periphery of the cover 2. Here, "periphery" refers to the circumferential side position of the edge of the cover 2, and "evenly distributed" means that each movable part 3 is arranged at equal angles or equal intervals along the periphery of the cover 2.

[0088] The number of movable parts 3 is not specifically limited in this application and can be determined according to the shape and size of the cover 2 and the required number of locking points. In some embodiments, there may be two movable parts 3, which are respectively located on two opposite sides of the cover 2, such as the left and right sides, or the front and rear sides, forming a pull-locking mechanism on both sides of the cover 2, which is simple in structure and easy to operate. In other embodiments, there may be three movable parts 3, which are distributed at 120° intervals along the periphery of the cover 2, suitable for the three sides of a triangular or square cover 2, forming a triangular stable locking structure. In still other embodiments, there may be four movable parts 3, which are respectively located on the four sides of the cover 2, that is, one movable part 3 on each of the front, rear, left, and right sides of the cover 2, and the four movable parts 3 are evenly distributed along the periphery of the cover 2, with an included angle of 90° between each two adjacent movable parts 3, forming a balanced four-sided locking mechanism. In embodiments where the cover 2 is rectangular or square, four movable parts 3 are respectively located at the middle of the four sides to achieve uniform force distribution on each side.

[0089] The number of movable parts 3 can also be five, six or more, depending on the circumference and size of the cover 2. The arrangement of multiple movable parts 3 enables a multi-point, multi-directional locking fit between the cover 2 and the box 1. Each movable part 3 applies a locking force to different sides of the cover 2, thereby achieving a balanced all-round locking between the cover 2 and the box 1.

[0090] Each movable component 3 serves as an independent locking unit, and each locking unit is equipped with a corresponding connector 5 and reset component 4. The connector 5 on each movable component 3 engages with the corresponding connector hole 111 located on the outer frame 11. The reset component 4 on each movable component 3 provides a reset force toward the locked position for its respective movable component 3. The specific structure and connection method of the multiple movable components 3, connectors 5, and reset components 4 can be found in the aforementioned embodiments. The structure of each locking unit can be identical to facilitate standardized production and mass assembly; alternatively, different sizes can be used depending on the location of each locking unit. For example, the movable component 3 located on the long side of the cover 2 can be equipped with a larger connector 5, while the one located on the short side can be equipped with a smaller connector 5.

[0091] The battery housing 10 provided in this application embodiment achieves multi-point, multi-directional balanced locking between the cover 2 and the housing 1 by evenly distributing multiple movable parts 3 along the periphery of the cover 2, and independently connecting the plug-in part 5 and the reset part 4 to each movable part 3. This effectively avoids the problems of local stress concentration and uneven sealing that may be caused by single-point or double-sided locking, and significantly improves the connection stability and sealing reliability of the battery housing 10 under complex vibration conditions.

[0092] Please see Figure 1 and Figure 5 Based on the same concept, this application also provides a battery 100. The battery 100 includes a battery housing 10 and battery cells. The battery housing 10 is as described in the foregoing embodiments. The battery cells are installed within a receiving cavity.

[0093] The battery 100 provided in this embodiment is a power battery 100 for a new energy vehicle 1000, and its type can be a ternary lithium battery 100, a lithium iron phosphate battery 100, or other types of rechargeable batteries 100. The battery 100 serves as the power energy device for the vehicle 1000, providing electrical energy to the vehicle 1000's drive motor 200 and on-board electrical equipment. The battery housing 10 serves as the supporting and protective structure for the battery 100, and its specific structure and technical features have been described in detail in the above embodiments, and will not be repeated here. The accommodating cavity provided by the battery housing 10 provides a closed, safe, and sealed installation space for the battery cells.

[0094] The number of battery cells is not specifically limited in this application. One, two, multiple, a dozen, several dozen, or more battery cells can be provided depending on the rated voltage and capacity requirements of the battery 100. When multiple battery cells are provided, they can be electrically connected in series, parallel, or a combination of series and parallel connections to form the required voltage platform and capacity. The type of battery cell can be cylindrical, square aluminum-cased, or pouch cell. In some embodiments, the battery cell can be cylindrical, with multiple cylindrical cells arranged in an array within the receiving cavity, and adjacent cells electrically connected through a busbar. In other embodiments, the battery cell can be square aluminum-cased, with square cells arranged along the length and width directions within the receiving cavity, and cells connected in series or parallel through conductive connecting pieces. In still other embodiments, the battery cell can be a pouch cell, which is flat, and multiple pouch cells are stacked and installed within the receiving cavity.

[0095] There are several ways to install the battery cells within the housing cavity. In some examples, the battery cells can be fixed to the base plate of the housing cavity using structural adhesive, with the adhesive layer firmly bonding the battery cells to the base plate to prevent the battery cells from shifting during vehicle 1000 operation. In other examples, the battery cells can be fixedly installed within the housing cavity using battery cell brackets. The battery cell brackets position and hold multiple battery cells in preset positions, and the battery cell brackets are then fixed to the base plate or outer frame 11 using threaded fasteners. In still other examples, the battery cells can be fixed within the housing cavity using straps or pressure strips. The straps are wrapped around the outside of multiple battery cells and fixed to the housing 1.

[0096] The cavity also houses electrical components such as a battery management system (BMS) circuit board and sampling harness. The battery management system is used to monitor the voltage, current and temperature parameters of each cell, and to realize the charging and discharging management and thermal management of the battery.

[0097] According to the battery 100 provided in the embodiments of this application, by adopting the battery housing 10 of the aforementioned embodiments, while ensuring effective sealing and protection of the battery cells, the cover 2 and the housing 1 can be quickly disassembled and assembled without tools, significantly improving the after-sales maintenance efficiency of the battery 100. Simultaneously, the multi-point, multi-directional locking structure ensures that the cover 2 will not loosen under vehicle vibration and impact conditions, ensuring the overall structural stability and long-term safety and reliability of the battery 100. Furthermore, the excellent sealing performance of the battery housing 10 provides a stable working environment for the battery cells, helping to extend the lifespan of the cells and ensure the performance output of the battery 100 system.

[0098] Please see Figure 5 Based on the same concept, this application also provides a vehicle 1000.

[0099] The vehicle 1000 includes a body and a battery 100. As described in the aforementioned embodiments, the battery 100 is mounted on the body and is used to provide electrical energy to the vehicle 1000.

[0100] The vehicle body is the main load-bearing structure of the vehicle 1000, providing a mounting base for the various components of the vehicle 1000 and forming the passenger and cargo space of the vehicle 1000. The vehicle body can be a monocoque structure or a body-on-frame structure. The vehicle 1000 can be a pure electric passenger vehicle, a hybrid passenger vehicle, or an electric commercial vehicle, such as a sedan, a sports utility vehicle, a multi-purpose vehicle, a truck, or a bus.

[0101] The vehicle body defines a space for installing the battery 100, which is then installed within this space. The battery 100 serves as the power source for the vehicle 1000, providing electrical energy to the drive motor 200 to propel the vehicle 1000. It also provides electrical energy to the vehicle's onboard electrical equipment. The specific structure and composition of the battery 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0102] The specific location of the battery 100 within the vehicle body can be determined based on the type of vehicle 1000 and its chassis layout. In some embodiments, the battery 100 can be installed at the bottom of the vehicle body, i.e., below the chassis of the vehicle 1000. This arrangement helps lower the center of gravity of the vehicle 1000, improves driving stability, and facilitates heat dissipation and protection of the battery 100. The battery 100 can be bolted to a mounting beam at the bottom of the vehicle body. In other embodiments, the battery 100 can be installed in the trunk area of ​​the vehicle body. This arrangement is suitable for some commercial vehicles 1000 or models with special requirements for chassis space. The battery 100 is fixed to the floor or side wall of the trunk using brackets. In still other embodiments, the battery 100 can be installed in the front compartment of the vehicle body, i.e., where the engine of a traditional gasoline vehicle is located. This arrangement is suitable for some range-extended electric vehicles 1000 or hybrid vehicles 1000.

[0103] There are several ways to connect the battery 100 to the vehicle body. In some examples, the outer frame 11 of the battery housing 10 has mounting ears with mounting holes, and the corresponding position on the vehicle body has threaded holes or welded nuts. A bolt is passed through the mounting hole and screwed into the threaded hole to fix the battery 100 to the vehicle body. In other examples, the bottom of the battery housing 10 has a slide rail structure, and the corresponding slide groove is provided on the vehicle body. The battery 100 slides into the slide groove via the slide rail and is then locked to the vehicle body by a locking mechanism. This method facilitates the assembly, disassembly, and maintenance of the battery 100. In still other examples, the battery 100 can be fixed to the vehicle body by straps or hoops. The straps are wrapped around the outer periphery of the battery housing 10 and connected to the vehicle body.

[0104] Battery 100 provides electrical energy to vehicle 1000. During vehicle 1000 operation, the electrical energy stored in battery 100 is transmitted to drive motor 200 via a high-voltage power distribution system. Drive motor 200 converts the electrical energy into mechanical energy, which is then transmitted to the wheels via a transmission system, thus driving vehicle 1000. Battery 100's management system monitors and manages the charging and discharging process in real time, ensuring that battery 100 operates within safe voltage, current, and temperature ranges. When the battery 100's charge level falls below a preset threshold, vehicle 1000 can recharge battery 100 using an external charging device, restoring the electrical energy to battery 100.

[0105] During the use of vehicle 1000, battery 100 is subjected to continuous vibration and impact from the road surface as vehicle 1000 moves. By adopting the battery housing 10 of the aforementioned embodiments, the cover 2 and housing 1 are reliably connected through a multi-point plug-in locking mechanism. Combined with the continuous reset force provided by reset component 4 and the auxiliary holding of the magnetic structure, cover 2 remains firmly locked under the vibration conditions of vehicle 1000 operation, preventing it from loosening. This provides continuous and stable sealing protection for the cells and electrical components inside battery 100. When after-sales maintenance, fault diagnosis, or cell module replacement of battery 100 is required, maintenance personnel do not need any disassembly or assembly tools. They can quickly unlock and remove cover 2 simply by operating the operating components 8 at each moving part 3. This convenient and efficient operation significantly shortens maintenance time and reduces maintenance costs. Furthermore, reinstallation of cover 2 after disassembly also requires no tools, as the reset component 4 automatically resets and locks, avoiding the risk of sealing failure due to loose bolts or improper torque.

[0106] According to the vehicle 1000 provided in the embodiments of this application, by adopting the battery 100 of the aforementioned embodiments, while ensuring the structural stability and sealing reliability of the battery 100 during vehicle 1000 operation, the ease of maintenance of the battery 100 is significantly improved. This effectively solves the problems of low disassembly and assembly efficiency or insecure locking of the battery pack cover in existing vehicle 1000s, greatly facilitating after-sales repair and routine maintenance of the vehicle 1000. Simultaneously, the excellent sealing and protection performance of the battery housing 10 provides a stable and reliable working environment for the cells inside the battery 100, ensuring the long lifespan of the battery 100 and the overall driving safety of the vehicle 1000.
