[0004] To solve the above problems, the technical solution provided by this utility model embodiment is as follows:

[0005] In a first aspect, this utility model provides a protective compartment, comprising: a shell having a receiving cavity and an opening communicating with the receiving cavity; a door movably connected to the shell and capable of opening or closing the opening; and a latch mounted on the shell, the latch cooperating with the door to switch the door between locking and unlocking; wherein the latch at least abuts against the door when unlocked to push the door to move in the direction of opening the opening.

[0006] In some embodiments, the latch includes: a lock head that reciprocates between a first position and a second position relative to the door body; the lock head locks the door body in the first position and unlocks the door body in the second position; an unlocking part for pressing during unlocking; and a hinge part disposed between the lock head and the unlocking part; wherein, when the unlocking part is pressed, the lock head swings around the hinge part, can move from the first position to the second position to unlock, and can push the door body to rise.

[0007] In some embodiments, the latch further includes a first elastic element disposed between the unlocking part and the housing, the first elastic element being used to drive the unlocking part to reset so that the lock head is synchronously reset to the first position.

[0008] In some embodiments, the lock head is provided with a latch and a lifting block spaced apart, the latch being closer to the second position and the lifting block being closer to the first position; wherein, when locking the door, the locking part on the door is located in the gap between the latch and the lifting block.

[0009] In some embodiments, two lifting blocks are spaced apart along a first direction, and the orthographic projection of the locking tongue in a second direction is located between the two lifting blocks, wherein the first direction is perpendicular to the second direction.

[0010] In some embodiments, the lock head has an internal receiving groove, and a through hole communicating with the receiving groove is provided on one side wall facing the door body, and the lock tongue is installed in the receiving groove; wherein, one end of the lock tongue extends out from the through hole so as to abut against the locking part on the door body.

[0011] In some embodiments, the latch further includes a second elastic member disposed within the receiving groove and abutting against the other end of the latch; wherein the second elastic member pushes the latch to reset, so that one end of the latch extends out of the through hole.

[0012] In some embodiments, the protective compartment is further provided with an elastic seal located between the door and the housing and surrounding the opening. The elastic seal compresses and deforms when the door closes the opening to seal it.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0026] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0027] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0028] Firstly, such as Figure 1 As shown, this embodiment of the present invention provides a protective compartment that can be used to store electronic products such as rechargeable batteries, outdoor lighting fixtures, and cameras. It should be noted that the application scenarios provided in this embodiment do not limit the structure of the protective compartment. For ease of explanation, the following explanation will use a protective compartment for accommodating rechargeable batteries (not shown) as an example.

[0029] like Figures 1-3As shown, the protective compartment includes a housing 1, a door 2, and a latch 3. The housing 1 forms a receiving cavity 11, which serves as a storage space for a rechargeable battery. The housing 1 also has an opening 12 communicating with the receiving cavity 11, meaning the opening 12 penetrates the housing wall of the housing 1, allowing the receiving cavity 11 to connect with the external environment. The door 2 is movably connected to the housing 1 and can open or close the opening 12; specifically, the door 2 can rotate or translate with the housing 1. In the state where the door 2 is closed (refer to...), the opening 12 is closed. Figure 2 The housing 1 and the door 2 form a closed space for the receiving cavity 11, which can effectively protect the rechargeable battery from water and dust; when the door 2 is open at the opening 12 (refer to...) Figure 1 The rechargeable battery in the receiving cavity 11 can be inspected and repaired through the opening 12, and the rechargeable battery in the receiving cavity 11 can also be charged through the opening 12.

[0030] In order to accommodate outdoor use, the protective compartment requires a high degree of airtightness. Therefore, the door is tightly connected to the shell when the opening is closed, making it inconvenient to open. It requires a large force or tools to open the door, which is not conducive to user use.

[0031] like Figures 3-5 As shown, where, Figure 3 The diagram shows door 2 in the locked state. Figure 4 The diagram shows door 2 in the unlocked state. In this embodiment of the invention, to improve the ease of opening door 2, a latch 3 is installed on the housing 1. The latch 3 can cooperate with door 2 to switch door 2 between locked and unlocked states. Moreover, the latch 3 at least abuts against door 2 when unlocked, pushing door 2 toward opening 12 (see reference). Figure 1 The door 2 moves in the direction of opening. That is to say, the latch 3 will function when the door 2 is locked and when the door 2 is unlocked. When the door 2 is unlocked, the latch 3 can abut against the door 2, thereby pushing the door 2 to move in the direction of opening 12, so that the door 2 is pushed and raised to a certain height, so that the user can operate the door 2 to flip it open and open 12.

[0032] Specifically, such as Figure 3 and Figure 4 As shown, the latch 3 can apply a downward force to the door body 2, causing the door body 2 to tend to move downwards. The door body 2 fits tightly with the housing 1, forming a "lock," which ensures the sealing of the receiving cavity 11 by effectively closing the opening 12; and the latch 3 can... Figure 5 In the schematic diagram, an upward force is applied to the door 2, which can be simply understood as the latch 3 lifting the door 2, causing the door 2 to move away from the housing 1 and open the opening 12 (see reference). Figure 1This forms an "unlocked" state. With the free end of door 2 separated from housing 1, door 2 is no longer restricted by latch 3, reducing the possibility that door 2 cannot be opened due to high friction between door 2 and housing 1. Moreover, compared to door 2 being flush with housing 1, after latch 3 lifts the free end of door 2, the user can directly apply force to the free end of door 2 and move door 2 to fully expose opening 12 (see reference). Figure 1 This design makes it easier and less strenuous to open door 2. Furthermore, the latch 3 can not only lock door 2 but also unlock it, offering more versatile functionality without requiring additional components.

[0033] Of course, it is understandable that, such as Figure 1 As shown, in some possible implementations, an additional elastic element can be provided in addition to the latch 3. For example, the elastic element can be a spring ball 14. When the door 2 is locked, the spring ball 14 abuts between the door 2 and the housing 1. In this way, when the latch 3 unlocks the door 2, the elastic force released by the spring ball 14 can also drive the door 2 to move in the direction of the opening 12.

[0034] This utility model provides a protective compartment including a housing 1, a door 2, and a latch 3. The housing 1 has a receiving cavity 11 and an opening 12 communicating with the receiving cavity 11. The door 2 is movably connected to the housing 1 and can open or close the opening 12. The latch 3 is mounted on the housing 1 and can switch the door 2 between locked and unlocked. The latch 3 abuts against the door 2 at least when unlocked to push the door 2 toward the opening 12. With this configuration, since the latch 3 can push the door 2 when unlocked, the user only needs to move the door 2 after the latch 3 lifts it up, thus requiring less force to fully open the opening 12, making it easier and more convenient to open the door 2 and improving the user experience. In addition, the latch 3 can not only lock the door 2 but also unlock it, making it more versatile and ingeniously designed.

[0035] In some embodiments, such as Figures 4-6 As shown, the latch 3 includes a lock head 31, an unlocking part 32, and a hinge part 33. It should be noted that this utility model embodiment only divides the latch 3 into three areas—lock head 31, unlocking part 32, and hinge part 33—according to function, and does not divide the latch 3 into parts. That is to say, the lock head 31, unlocking part 32, and hinge part 33 can be integrally formed, or one or more of the lock head 31, unlocking part 32, and hinge part 33 can be independent parts, which are then connected to form a whole component.

[0036] The lock head 31 reciprocates between a first position and a second position relative to the door body 2. In the first position, the lock head 31 locks the door body 2, and in the second position, it unlocks the door body 2. Figure 4 The diagram shows the lock head 31 in the first position. Figure 5 This is a schematic diagram showing the lock head 31 in the second position. To facilitate explanation of the movement direction of the door body 2 and the latch 3, assume that the door body 2 is located in the height direction, with the end of the door body 2 as the upper end of the housing 1, and consider the direction of opening the door body 2 as upward. Then, it can be understood that the height of the lock head 31 in the second position is higher than that in the first position. The lock head 31 in the second position raises the free end of the door body 2, causing the free end of the door body 2 to separate from the housing 1, thus unlocking. The unlocking part 32 is used for pressing during unlocking; that is, during unlocking, the unlocking part 32 moves downward, and the lock head 31 moves upward. The hinge part 33 is located between the lock head 31 and the unlocking part 32. When the unlocking part 32 is pressed, the lock head 31 swings around the hinge part 33, allowing the lock head 31 to move from the first position to the second position for unlocking, and also pushing the door body 2 to rise. It can be understood that the latch 3 is a lever structure, the unlocking part 32 is the force-applying end of the lever structure, the lock head 31 is the free end of the lever structure, and the hinge part 33 forms the fulcrum of the lever structure. Therefore, when the unlocking part 32 is pressed, the lock head 31 moves in the opposite direction of the pressing direction, lifting the free end of the door 2. For example, pressing the unlocking part 32 downwards causes the lock head 31 to move upwards around the hinge part 33, abutting against the free end of the door 2 and pushing the free end of the door 2 upwards, thereby raising the free end of the door 2 to a position separated from the housing 1, thus unlocking. In this way, using a lever structure to lift the free end of the door 2 requires less effort and makes it easier for the user to open the door 2.

[0037] In some embodiments, such as Figure 4 and Figure 5 As shown, the latch 3 also includes a first elastic element 34, which abuts against the unlocking part 32 and the housing 1. The first elastic element 34 is used to drive the unlocking part 32 to reset, so that the lock head 31 is synchronously reset to the first position. Specifically, when the unlocking part 32 is pressed, the first elastic element 34 is compressed. After the external force is released, the first elastic element 34 releases its elastic force and lifts the unlocking part 32, thereby causing the lock head 31 to reset around the hinge part 33. The lock head 31 rotates in the opposite direction (downward) to the movement direction of the unlocking part 32. In this way, the elastic force of the first elastic element 34 enables the unlocking part 32 and the lock head 31 to automatically reset without manual reset, saving time and effort, and making the operation simple and easy to implement.

[0038] In some embodiments, such as Figure 3 and Figure 6As shown, a latch 311 and a lifting block 312 are spaced apart on the lock head 31. The latch 311 is closer to the second position, and the lifting block 312 is closer to the first position. That is, the height of the latch 311 is higher than the height of the lifting block 312. When locking the door 2, the locking part on the door 2 is located in the gap between the latch 311 and the lifting block 312. For ease of explanation, the locking part on the door 2 is defined as the limiting part 21. In the locked state of the door 2, the limiting part 21 is located between the latch 311 and the lifting block 312. In this way, the latch 311 can be used to restrict the movement of the door 2 towards the opening 12, thereby locking the door 2. At the same time, the lifting block 312 abuts against the door 2 when the door 2 is locked. Therefore, when unlocking, the free end of the door 2 can be directly lifted, so that the free end of the door 2 separates from the housing 1, making the opening of the door 2 more efficient. It should be noted that during unlocking, the lifting block 312 and the door body 2 rotate relative to each other. Therefore, if the latch 3 and the door body 2 continue to rotate during unlocking, the distance between the free end of the door body 2 and the lifting block 312 will gradually increase. Since the latch 311 is spaced apart from the lifting block 312, and because the lifting block 312 is close to the first position, when the lifting block 312 lifts the free end of the door body 2 to rotate, the distance between the free end of the door body 2 and the latch 311 will also gradually increase, gradually moving away from the free end of the door body 2, thus unlocking the limiting part 21 without interfering with the movement trajectory of the door body 2 during unlocking. Thus, by setting mutually spaced latches 311 and lifting blocks 312 on the lock head 31, the latch 311 locks the door body 2, and the lifting block 312 unlocks the door body 2, allowing for one-button unlocking and locking of the door body 2. The design is ingenious and the structure is simple.

[0039] In some embodiments, such as Figure 5 and Figure 6 As shown, two lifting blocks 312 are spaced apart along the first direction. Thus, multiple lifting blocks 312 together lift the free end of the door 2 during unlocking, resulting in a larger contact area and lifting arm, enabling faster and more reliable lifting of the door 2. Of course, in some possible implementations, the number of lifting blocks 312 can be greater than two; for example, the number of lifting blocks 312 can be three, four, or five. Specifically, when the number of lifting blocks 312 is an odd number greater than two, one lifting block 312 is located at the center of the lock head 31, and the remaining lifting blocks 312 are symmetrically distributed on both sides of the centrally located lifting block 312; when the number of lifting blocks 312 is an even number greater than two, each lifting block 312 is symmetrically distributed about the center line of the lock head 31.

[0040] like Figure 5 and Figure 6As shown, the orthographic projection of the latch 311 in the second direction is located between the two lifting blocks 312, where the first direction is perpendicular to the second direction. It should be noted that the orthographic projection of the latch 311 in the second direction represents the shadow cast by light rays along the second direction onto the latch 311 in the first direction. In other words, the distance between the latch 311 and the lifting blocks 312 is in the second direction (the height direction shown in the schematic diagram). If the distance between the latch 311 and the lifting blocks 312 in the second direction is ignored, the latch 311 is located between the two lifting blocks 312. Figure 6 In the schematic diagram shown, N1 represents the first direction and N2 represents the second direction. With this configuration, the latch 311 has lifting blocks 312 on both sides in the first direction. It can be simply understood that the latch 311 is located in the middle of the two lifting blocks 312. When unlocking, the lifting blocks 312 on both sides of the latch 311 lift the door body 2, which allows the latch 311 to move away from the limiting part 21 without tilting. This reduces the interference of the latch 311 on the movement trajectory of the door body 2 when the door body 2 is unlocked, and can reliably unlock the door body 2.

[0041] In some embodiments, such as Figure 3 and Figure 6 As shown, the lock head 31 has an internal receiving groove 313, and a through hole 314 communicating with the receiving groove 313 is provided on one side wall facing the door body 2. That is, the through hole 314 is only provided on one side wall of the lock head 31, and the receiving groove 313 communicates with the outside through the through hole 314. The lock tongue 311 is installed in the receiving groove 313, and one end of the lock tongue 311 extends out of the through hole 314 so as to abut against the locking part on the door body 2. Specifically, the free end of the door body 2 can have a slot 22 adapted to the lock tongue 311. After the lock tongue 311 extends out, it is engaged in the slot 22, and the lock tongue 311 abuts against the end face of the limiting part 21 connected to the slot 22 to lock the door body 2. In this way, the lock tongue 311 is set as an independent component that can be disassembled and installed in the receiving groove 313, which facilitates the adjustment of the structural parameters of the lock tongue 311 and also makes it easier to adjust the lock tongue 311 individually and quickly. In addition, the receiving groove 313 provides storage space for the latch 311. When unlocking, the latch 311 can be abutted by the limiting part 21 and retract into the receiving groove 313 so that the latch 311 can quickly unlock the door 2, thereby opening the door 2 more conveniently.

[0042] In some embodiments, such as Figure 3As shown, the latch 3 also includes a second elastic member 35 disposed within the receiving groove 313. The second elastic member 35 abuts against the other end of the latch 311, that is, the second elastic member 35 abuts against the end of the latch 311 housed within the receiving groove 313. The second elastic member 35 can push the latch 311 back to its original position, so that one end of the latch 311 extends out of the through hole 314. Specifically, during unlocking, the latch 311 retracts into the receiving groove 313 due to the restraint portion 21, and the door 2 moves away from the area where the latch 3 is located (see reference). Figure 1 The second elastic element 35 drives the locking tongue 311 to extend automatically; when locked, the locking tongue 311 retracts into the receiving groove 313 by the limiting part 21 abutting against it, and after the limiting part 21 moves to the gap between the locking tongue 311 and the lifting block 312 (see reference). Figure 3 The second elastic element 35 drives the bolt 311 to extend automatically, thereby locking the door 2. In this way, the second elastic element 35 can drive the bolt 311 to automatically reset without manual reset, which is more labor-saving. Moreover, the automatic drive of the second elastic element 35 has a faster response speed, which can quickly lock the door 2.

[0043] In some embodiments, such as Figure 1 As shown, the protective compartment is also equipped with an elastic seal. The elastic seal is located between the door 2 and the housing 1, and is arranged around the opening 12, that is, the elastic seal is approximately annular. The elastic seal compresses and deforms when the door 2 closes the opening 12, thereby sealing the opening 12. In this way, the compressed elastic seal fills the gap between the door 2 and the housing 1 (see reference). Figure 3 The opening 12 is sealed tightly, reducing the risk of water and dust entering through the opening 12, improving the safety of the rechargeable battery, and making the protective compartment suitable for outdoor use, thus making it more widely applicable.

[0044] In some embodiments, such as Figure 1 As shown, the housing 1 has a first connecting portion 13 on the side facing the door 2, and an opening 12 passes through the first connecting portion 13. The door 2 has a second connecting portion 23 on the side facing the opening 12, which is adapted to the first connecting portion 13. One of the first connecting portion 13 and the second connecting portion 23 is configured as a step, and the other is configured as a limiting groove adapted to the step. Specifically, the first connecting portion 13 can be configured as a step, and the second connecting portion 23 can be configured as a limiting groove, so that when the door 2 is locked, the outer side of the first connecting portion 13 can be located inside the second connecting portion 23 (see reference). Figure 3 Alternatively, the second connecting part 23 can be configured as a step, and the first connecting part 13 can be configured as a limiting groove, so that when the door 2 is locked, the outer side of the second connecting part 23 can be located inside the first connecting part 13.

[0045] like Figure 1 and Figure 3As shown, with the door 2 closed at opening 12, the elastic seal is sealed between the side of the step and the wall of the limiting groove. Thus, the compressed elastic seal abuts against the side of the step and the wall of the limiting groove. The friction between the side of the step and the elastic seal, and between the wall of the limiting groove and the elastic seal, are both relatively large, allowing for a good seal between the door 2 and the housing 1, improving the waterproof and dustproof performance of the protective shell.

[0046] Secondly, such as Figure 1 As shown, this embodiment of the present invention also provides a portable battery pack, which includes the protective compartment described in the first aspect. The portable battery pack also includes a rechargeable battery for powering an outdoor cycling device, the rechargeable battery being installed in the receiving cavity 11 of the protective compartment. Specifically, the outdoor cycling device can be an electric bicycle equipped with an electric assist system, such as a mountain bike or a city bike. Because the portable battery pack includes the protective compartment described in the first aspect, it has the same technical effect: the opening 12 can be opened more easily and quickly, making it more convenient to charge or repair the rechargeable battery. Furthermore, the portable battery pack uses a single component (lock 3) to unlock and lock the door 2, making the overall structure simpler and easier to operate.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
