[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please refer to Figures 1 to 3This utility model provides a battery compartment cover, which includes a cover body, a pin 4, and a toggle switch 3. The pin 4 is movably connected to the cover body, and the cover body can be engaged with the battery compartment via the pin 4. The toggle switch 3 is movably connected to the cover body, and there is a preset gap between the toggle switch 3 and the pin 4, i.e., the toggle switch 3 and the pin 4 are separate structures. When it is necessary to open the battery compartment cover, the toggle switch 3 can be moved so that the toggle switch 3 moves relative to the cover body by the preset gap, thereby causing the pin 4 to move synchronously, thus removing the pin 4 from the battery compartment, thereby unlocking the battery compartment cover. Because the toggle switch 3 and the pin 4 are separate designs, they do not act on the pin 4 within the initial movement distance. Therefore, even if the toggle switch 3 is pushed within this distance, it will not cause the pin 4 to be pushed. This can prevent the problem of the battery compartment cover being opened abnormally due to accidental activation of the toggle switch 3 during use.

[0045] In some embodiments, the battery compartment cover body is provided with a movable cavity 11, the dial 3 is provided with a push part 33 located in the movable cavity 11, the pin 4 is movably provided in the movable cavity 11, the pin 4 is provided with a push block 41, and there is a preset gap between the push block 41 and the push part 33. When it is necessary to open the battery compartment cover body, the dial needs to be moved by the distance of the preset gap so that the push part 33 and the push block 41 come into contact. When the dial 3 is moved further, the pin 4 will be driven to retract into the movable cavity 11, thereby realizing the unlocking operation of the battery compartment cover, that is, the battery compartment cover can be opened from the battery compartment to facilitate the removal and placement of the battery.

[0046] In some embodiments, the cover body is provided with a toggle groove 21 communicating with the movable cavity 11, and one side of the movable cavity 11 is provided with a telescopic groove 12 communicating with the outside; the knob 3 is provided with a toggle part 31, which extends out of the toggle groove 21 to facilitate user operation of the toggle part 31. The length of the toggle part 31 in the movable direction of the knob 3 is less than the extension length of the toggle groove 21 in the movable direction of the knob 3. The knob 3 is provided with a push part 33, which is located at one end of the knob 3 near the telescopic groove 12; the pin 4 is provided in the movable cavity 11 and can move relative to the movable cavity 11. The push block 41 is located at one end of the pin 4 away from the telescopic groove 12, and the push block 41 is located on the side of the push part 33 opposite to the telescopic groove 12. When one end of the pin 4 extends out of the telescopic groove 12, the pin 4 is in a state of being engaged with the battery compartment. At this time, there is a preset gap between the push part 33 of the knob 3 and the push block 41 of the pin 4. When the dial 3 moves backward by a preset gap, the pusher 33 will drive the pusher 41 to move backward synchronously, thereby disengaging the pin 4 from the snap-fit ​​position of the battery compartment.

[0047] In some embodiments, the movable cavity 11 is provided with a first elastic element 5 and a second elastic element 6, wherein the first elastic element 5 can provide a pushing force to the dial 3 toward the pin 4, and the second elastic element 6 can provide a pushing force to the pin 4 toward the outlet of the telescopic groove 12; the actuating part 31 abuts against the front wall of the actuating groove 21 under the action of the first elastic element 5, and one end of the pin 4 extends out of the telescopic groove 12 under the action of the second elastic element 6 to engage with the battery compartment. At this time, there is a preset gap between the pushing part 33 and the pushing block 41 in the movable direction. When it is necessary to open the battery compartment cover from the battery compartment, the dial 3 is pushed. Since there is a preset gap between the pushing part 33 of the dial 3 and the pushing block 41 of the pin 4, the dial 3 will move first, specifically as follows: Figure 3 As shown, when the moving distance reaches the preset gap length, the toggle part 31 will contact the push block 41. As the toggle button 3 continues to move backward, the pin 4 will move backward, thereby retracting the front end of the pin 4 into the telescopic groove 12 to unlock the battery compartment cover. Specifically, as shown... Figure 4 As shown. Since the toggle switch 3 and the latch 4 are separate designs, they do not act on the latch 4 during the initial movement. Therefore, even if the toggle switch 3 is pushed backward within this distance, the latch 4 will not be pushed back. This prevents the user from accidentally touching the toggle switch 3 and causing the battery compartment cover to open abnormally.

[0048] In some embodiments, such as Figure 2 As shown, the lower end of the dial 3 is provided with a clearance groove 32 that divides it into a support part 34 and a push part 33. The structure at the front end of the clearance groove 32 on the dial 3 is the push part 33, and the structure at the rear end of the clearance groove 32 is the support part 34. The two ends of the first elastic member 5 are respectively pressed against the rear wall of the movable cavity 11 and the rear end of the support part 34. The push block 41 is located in the clearance groove 32. The length of the clearance groove 32 in the front-rear direction is greater than the length of the push block 41 in the front-rear direction. The clearance groove 32 is mainly to avoid contact with the push block 41 when the dial 3 is moved a short distance. The side of the push block 41 facing the opening of the telescopic groove 12 and the side of the clearance groove 32 facing the push block 41 are perpendicular to the movable direction of the dial 3. For example, Figure 2 As shown, the front of the push block 41 and the front wall of the clearance groove 32 are preferably perpendicular to the forward and backward movement direction of the dial 3. The cross-sectional shape of the clearance groove 32 and the push block 41 can be a right trapezoid or a right triangle. The rear end face of the toggle part 31 is referred to as the front wall of the clearance groove 32. By having the toggle part 31 contact the push block 41, the stability of the dial 3 when pushing the pin 4 backward can be improved.

[0049] In some embodiments, such as Figure 1 and Figure 2As shown, the pin 4 is provided with a groove 42, and the rear end of the groove 42 forms a push block 41. The pushing part 33 is located in the groove 42. The length of the pushing part 33 in its movable direction is less than the length of the groove 42 in the movable direction of the pin 4, that is, the pushing part 33 can move relative to the groove 42 in the front-back direction. Under the action of the first elastic member 5, the button 3 will cause the pushing part 33 to push the front wall of the groove 42, thereby pushing the pin 4 forward. The second elastic member 6 will also push the pin 4 forward. That is, the pin 4 can be subjected to the pushing force of the first elastic member 5 and the second elastic member 6, which can further improve the stability of the pin 4 when it is in the extended state. The telescopic groove 12 has a rectangular structure, and the structure of the pin 4 located in the telescopic groove 12 is also a plate structure. In order to facilitate the insertion of the front end of the pin 4 into the corresponding slot of the battery compartment, a forward-inclined guide slope can be provided at the front end of the pin 4.

[0050] In some embodiments, such as Figure 1 As shown, the inner bottom surface of the movable cavity 11 is provided with a receiving groove 13, and the second elastic member 6 is located in the receiving groove 13. The receiving groove 13 can ensure the stability of the second elastic member 6 when it extends and retracts. The pin 4 is provided with a limiting part 43 located in the receiving groove 13. The two ends of the second elastic member 6 abut against the rear wall of the receiving groove 13 and the rear end of the limiting part 43, respectively. The limiting part 43 contacts the front wall of the receiving groove 13, which can prevent the pin 4 from moving forward.

[0051] In some embodiments, the first elastic element 5 includes at least one first telescopic spring, and a plurality of first telescopic springs are distributed side by side, for example... Figure 1 As shown, multiple first telescopic springs are distributed along the left-right direction of the movable cavity 11. For example, two first telescopic springs are provided, and the second elastic element 6 is a second telescopic spring. In addition to telescopic springs, other elastic elements that can provide forward thrust can also be selected.

[0052] In some embodiments, one end of the support portion 34 is provided with a first connecting post, and one end of the first telescopic spring is sleeved on the first connecting post, for example... Figure 1 As shown, the rear end of the support part 34 is provided with a first connecting post, and the front end of the first telescopic spring is sleeved on the first connecting post. The first connecting post facilitates the installation of the first telescopic spring. One end of the limiting part 43 is provided with a second connecting post, and one end of the second telescopic spring is sleeved on the second connecting post. For example... Figure 2 As shown, the rear end of the limiting part 43 is provided with a second connecting post, and the front end of the second telescopic spring is sleeved on the second connecting post. The second connecting post facilitates the installation of the second telescopic spring.

[0053] In some embodiments, the bottom surface of the movable cavity 11 is provided with a guide groove extending along the movable direction of the dial 3, and the dial 3 is provided with a guide block that can move relative to the guide groove. Through the guide groove and the guide block, the accuracy of the movement of the dial 3 can be improved to avoid the problem of deflection. Two sets of guide grooves and guide blocks can be provided between the movable cavity 11 and the dial 3 to improve the stability of the movement of the dial 3.

[0054] In some embodiments, such as Figure 1 As shown, the bin cover body includes a bin cover bracket 1 and a bin cover shell 2. The bin cover shell 2 is connected to the upper end of the bin cover bracket 1. For example, the bin cover shell 2 can be fastened to the bin cover bracket 1. A movable cavity 11 is provided between the bin cover shell 2 and the bin cover bracket 1. During installation, the toggle button 3, the pin 4, the first elastic element 5 and the second elastic element 6 can be installed on the bin cover bracket 1 first, and then the bin cover shell 2 can be fastened to the bin cover bracket 1.

[0055] In some embodiments, such as Figure 1 As shown, the rear end of the battery compartment cover bracket 1 is provided with a hinge part 14, and the hinge part 14 is provided with a hinge hole 15. The hinge part 14 is used to be hinged to the battery compartment through the hinge shaft. The bottom of the battery compartment is provided with a spring. When the battery is put into the battery compartment, the bottom of the battery will contact the spring. Then, after the battery compartment cover is fastened to the battery compartment, the battery compartment cover will apply downward pressure to the battery, thereby compressing the spring. When the pin 4 is removed from the battery compartment, under the action of the spring in the battery compartment, it will apply upward thrust to the battery. Under the action of the battery, the end of the battery compartment cover with the pin 4 will spring up, so that the battery compartment cover will rotate around the hinge shaft, thereby opening the battery compartment.

[0056] This utility model embodiment also provides a battery housing, including the battery housing cover provided in any of the above embodiments, and a battery housing with an opening, the battery housing cover being detachably connected to the opening.
