[0026] See also Figure 1 , Figure 1 It is a structural schematic diagram of the first cross-sectional view of the battery compartment provided in this application.

[0027] The present application provides a battery compartment. Figure 1 As shown, the battery compartment of this embodiment includes: a shell 10 and a clamping member 40, the shell 10 is provided with at least one accommodating portion 20, the accommodating portion 20 forms a first accommodating space 202 with a first opening 201, and the first accommodating space 202 is formed with a first opening 201. Figure 3As shown, a battery 30 is disposed in the first accommodation space 202. The clamping member 40 is disposed on the end surface of the accommodation portion 20 away from the first opening 201, and is combined with Figure 2 As shown, at least one second opening 401 is provided on the side wall of the accommodating portion 20, and the clamping member 40 is disposed on the side wall of the second opening 401 close to the first opening 201, and the clamping member 40 clamps and fixes the battery 30. The battery 30 is disposed in the first accommodating space 202, and the battery 30 at least partially protrudes from the first opening 201, that is, the battery 30 can be inserted into the first accommodating space 202 through the first opening 201. The housing 10 includes a plurality of side walls, which are sequentially connected to form the first accommodating space 202, and the clamping member 40 is disposed on the side walls.

[0028] In an optional embodiment, a housing portion 20 is formed on the housing 10, and the housing portion 20 is formed by a plurality of side walls and a bottom wall connected to the side walls. The plurality of side walls are connected in sequence and one end is connected to one end of the housing 10, thereby forming a first housing space 202. The battery 30 can be inserted into the first housing space 202 through the first opening 201. When the battery 30 is inserted into the first housing space 202 for charging, it is obviously necessary to fix the battery 30, that is, after the battery 30 is inserted into the first housing space 202, the battery 30 needs to be fixed inside the first housing space 202. Therefore, a second opening 401 is opened on the side wall of one side of the housing portion 20, and a clamping member 40 is arranged on the side wall of the second opening 401 close to the first opening 201, that is, the clamping member 40 is arranged inside the second opening 401 of the side wall of the housing portion 20, and the plane where the end face of the clamping member 40 is located is flush with the plane where the side wall of the housing portion 20 is located. After the battery 30 is inserted into the first accommodating space 202 through the first opening 201 , the battery 30 can be fixed by the clamping member 40 inside the second opening 401 .

[0029] In this embodiment, the clamping member 40 is disposed inside the second opening 401, and one end of the clamping member 40 is connected to an end of the side wall of the accommodating portion 20 close to the first opening 201. That is, only one end of the clamping member 40 close to the first opening 201 is connected to the side wall of the accommodating portion 20. Figure 5As shown, the clamping member 40 is spaced apart from the side wall of the accommodating portion 20 in the direction perpendicular to the direction in which the battery 30 is inserted into the first accommodating space 202, and the end away from the first opening 201 is spaced apart from the side wall of the accommodating portion 20, that is, after the battery 30 is inserted into the first accommodating space 202 of the accommodating portion 20, the battery 30 can be fixed by the clamping member 40. When charging the battery 30, the battery 30 is fixed by the clamping member 40, and the end face of one side of the clamping member 40 is connected to the side wall of the accommodating portion 20, so that the other three sides of the clamping member 40 and the side wall of the accommodating portion 20 form a hollow. When the clamping member 40 fixes the battery 30, the deformation stress between the clamping member 40 and the battery 30 will be reduced, and the battery 30 does not need to be fixed by interference fit, which can effectively reduce the wear of the clamping member 40 and the battery 30, thereby improving the service life of the battery compartment and the battery 30.

[0030] In an optional embodiment, the housing 10 may be provided with a plurality of receiving portions 20, such as Figure 3 As shown, the present application takes the arrangement of four receiving parts 20 on the housing 10 as an example, that is, when charging the battery 30, four batteries 30 can be inserted into the receiving part 20, so as to charge the battery 30, wherein the four receiving parts 20 can be set to the same size, and can charge the same battery model, or can be set according to the battery models mainly used on the market, for example, the receiving part 20 is set according to different battery models, so that when the user uses the battery compartment, different models of batteries can be matched through different models of receiving parts 20 to meet the different needs of customers. It can also be customized according to the battery models used by customers on a daily basis. For example, the receiving parts 20 can be set to different models in pairs, which is not only convenient for customers to charge batteries of different models, but also batteries of the same model can be charged at the same time. Among them, the number of battery compartments can be customized according to needs, and this application does not make specific restrictions here.

[0031] In the above embodiment, by providing a receiving portion 20 on the shell 10 and forming a receiving space with a first opening 201 in the receiving portion 20, the battery 30 can be inserted into the first receiving space 202 and the battery 30 can be charged, a second opening 401 is opened on the side wall of the receiving portion 20, and a clamping member 40 is provided on the side wall of the receiving portion 20 of the second opening 401 close to the first opening 201, so that the battery 30 can be clamped and fixed, and a hollow space is formed between the clamping member 40 and the side wall of the receiving portion 20. When fixing the battery 30, the deformation stress between the clamping member 40 and the battery 30 will be reduced, which can effectively reduce the wear of the clamping member 40 and the battery 30, thereby improving the service life of the battery compartment and the battery 30.

[0032] In an optional embodiment, a warning component (not shown) may be provided inside the housing 10. After the battery 30 is fully charged inside the battery compartment, the warning component may issue a voice prompt or / and flash an alarm light to remind the user that the battery 30 is fully charged. Alternatively, after detecting that the battery 30 is inserted into the first accommodation space 202 of the accommodation portion 20, and detecting whether the battery 30 is already being charged, if the battery 30 is not being charged, the warning component may remind the user that a charging failure of the battery 30 has occurred. Similarly, a control component (not shown) may be provided. After the battery 30 is inserted into the first accommodation space 202 of the accommodation portion 20, the control component may control the battery compartment to charge the battery 30. The control component may set the maximum battery voltage for charging the battery 30 and detect the charging voltage. When the charging voltage of the battery 30 is higher than the battery voltage set by the battery compartment, the control component may cut off the battery compartment from charging the battery 30. At this time, the warning component may issue a warning to remind the user. The control component can collect the voltage of the battery 30 in real time during the charging process of the battery 30, so as to judge whether the battery 30 is fully charged according to the voltage of the battery 30. After the battery 30 has been fully charged, the control component can control the battery compartment to stop charging the battery, and remind the user through the warning component that the battery 30 has been fully charged.

[0033] In an optional embodiment, if Figure 3 As shown, a back shell 301 is provided on one end face of the battery 30, the plane size of the back shell 301 is larger than the plane size of the battery 30, and at least one buckle 302 is provided at one end of the back shell 301. Among them, the clamping member 40 provided on the accommodating portion 20 corresponds to the buckle 302 one by one, so that the battery 30 is clamped and fixed by the clamping member 40 and the buckle 302. The clamping member 40 and the buckle 302 can be set to two. After the battery 30 is inserted into the accommodating portion 20, it is convenient to plug and unplug the battery 30. The buckle 302 and the clamping member 40 can be set to any reasonable value such as 3 or 4, which is not specifically limited in this application. Among them, the accommodating portion 20 forms a second accommodating space 203 connected to the first accommodating space 202, the second opening 401 is set on the side wall of the second accommodating space 203, and the clamping member 40 is set in the second opening 401 of the second accommodating space 203. That is, a second accommodating space 203 communicating with the first accommodating space 202 is provided in the accommodating portion 20 . When the battery 30 is inserted into the battery compartment for charging, the back shell 301 of the battery 30 can be inserted into the second accommodating space 203 .

[0034] In this embodiment, when the battery 30 is inserted into the first accommodation space 202, the end of the back shell 301 with the buckle 302 is inserted into the second accommodation space 203, and the buckle 302 abuts against the clamping member 40, which is set as an elastic member. When the battery 30 is inserted into the accommodation portion 20 for charging, the battery 30 is located in the first accommodation space 202, and the end of the back shell 301 with the buckle 302 is located in the second accommodation space 203. Since the plane size of the back shell 301 is larger than the plane size of the battery 30, the first accommodation space 202 and the second accommodation space 203 in the corresponding accommodation portion 20 form a step-like structure, so that the battery 30 is easily inserted into the accommodation portion 20. At the same time, when the battery 30 is charged, it is not necessary to separate the battery 30 from the back shell 301, and it is not necessary to set other fixing structures to fix the battery 30.

[0035] In this embodiment, the snap-in component 40 is configured as an elastic component. After the battery 30 is inserted into the accommodating portion 20, the snap-ins 302 provided on the back shell 301 are snap-connected to the snap-in component 40 one by one, which can prevent excessive wear of the snap-in component 40 and the snap-ins 302 on the back shell 301 when the battery 30 is plugged in and out, and prevent the battery 30 from being not firmly fixed when the battery 30 is subsequently charged, thereby effectively improving the service life of the battery compartment and the battery 30.

That is, when the battery 30 is inserted into the first accommodating space 202 through the first opening 201, the protrusion 402 on the clamping member 40 can clamp and fix the buckle 302 on the back shell 301, and the buckle 302 is clamped to the side of the protrusion 402 away from the first opening 201, thereby applying a force to the battery 30 away from the first opening 201, so that the battery compartment can charge the battery 30. Among them, the protrusion 402 on the clamping member 40 is set to a circular arc-shaped protrusion structure, so as to facilitate the insertion and removal of the battery 30, and can also be set according to needs, for example, a triangular structure, which is not specifically limited in this application.

[0037] In an optional embodiment, if Figure 3As shown, the shell 10 and the side wall of the accommodating portion 20 form a third accommodating space 204, and a charging assembly 50 is arranged inside the third accommodating space 204, which is arranged on the side of the outer wall of the accommodating portion 20 away from the first opening 201. When the battery 30 is inserted into the first accommodating space 202 through the first opening 201, the clamping member 40 on the second accommodating space 203 clamps the buckle 302 on the back shell 301, thereby fixing the battery 30. At this time, the protrusion 402 on the clamping member 40 can give the battery 30 a force away from the first opening 201, so that the feeding point of the battery 30 abuts against the charging assembly 50, preventing poor contact when charging the battery 30.

[0038] In an optional embodiment, if Figure 1 As shown, the plane size of the first accommodating space 202 is larger than the plane size of the second accommodating space 203, so that a step portion 60 is formed between the first accommodating space 202 and the second accommodating space 203. That is, the length of the first accommodating space 202 in the insertion direction of the battery 30 is smaller than the length of the second accommodating space 203, so that a step portion 60 is formed on the accommodating portion 20, and the end surface of the battery 30 close to the buckle 302 can be located on the step portion 60, and the width of the step portion 60 can be adapted to the thickness of the battery 30. In this embodiment, combined with Figure 5 As shown, a third opening 601 is provided on the step portion 60, and the third accommodating space 204 is communicated with the first accommodating space 202 through the third opening 601, and the charging assembly 50 is at least partially exposed to the third opening 601. That is, the charging assembly 50 is arranged inside the first accommodating space 202, and the first accommodating space 202 and the third accommodating space 204 are communicated through the third opening 601, that is, the battery 30 assembly is arranged on the outer wall of the accommodating portion 20, and is abutted and connected with the battery 30 inserted in the first accommodating space 202 through the third opening 601, and the battery 30 can be fixedly abutted on the charging assembly 50 under the action of the clamping member 40 and the buckle 302. Among them, the charging assembly 50 can be the same size as the third opening 601, so that the charging assembly 50 is fixed in the third opening 601, and the position of the third opening 601 on the step portion 60 corresponds to the charging feeding point of the battery 30.

[0039] In an optional embodiment, if Figure 4As shown, the charging assembly 50 includes a support member 501, which is arranged on the bottom plate of the housing 10. A charging spring 502 is arranged at one end of the charging assembly 50 away from the support member 501, and the charging spring 502 abuts against the charging feed point of the battery 30. The support member 501 is arranged inside the first accommodating space 202 of the housing 10, and is fixedly arranged on the bottom plate of the housing 10, and is arranged relative to the step portion 60, that is, the support member 501 and the step portion 60 are on the same plane, so that when the charging assembly 50 is arranged on the support member 501, the charging assembly 50 can be at least exposed to the third opening 601, so as to facilitate abutment with the charging feed of the battery 30. The battery 30 spring of the charging assembly 50 is arranged at one end of the charging assembly 50 away from the support member 501. After the battery 30 is inserted into the first accommodating space 202 through the first opening 201, the charging feed point of the battery 30 abuts against the charging spring 502. Therefore, after the battery 30 is inserted into the accommodating portion 20, it is convenient for the charging component 50 to charge the battery 30, and the charging spring 502 can be an elastic metal spring, so as to prevent the charging spring 502 from having poor contact with the charging feed point of the battery 30 when charging the battery 30, thereby affecting the charging effect of the battery 30.

[0040] In an optional embodiment, if Figure 5 As shown, at least one limiting member 70 is provided on the side wall of the accommodating portion 20, which is movably connected to the back shell 301 and / or the battery 30. The accommodating portion 20 is formed by connecting a plurality of side portions in sequence, and the limiting members 70 on the side wall of the accommodating portion 20 can be provided around the accommodating portion 20, so as to limit the battery 30 in multiple directions. On the one hand, it can prevent the battery 30 from being misplaced when inserted into the first accommodating space 202, that is, through a plurality of limiting members 70, when the battery 30 is inserted into the first accommodating space 202 through the first opening 201, it can ensure that the charging feed point of the battery 30 corresponds to the charging spring 502 of the charging assembly 50, so as to effectively prevent the misplacement when the battery 30 is inserted. On the other hand, when charging the battery 30, it can prevent the battery 30 from being loose, thereby causing the battery 30 to be interrupted from charging.

[0041] In the above manner, the present application provides a housing portion 20 on the housing 10, and forms a housing space with a first opening 201 in the housing portion 20, so that the battery 30 can be inserted into the first housing space 202 for charging.
