In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figure 1 , Figure 2 As shown, a battery compartment provided in one embodiment of this application includes a support frame 100 and a pressing component 200. The support frame 100 is used to place the battery 10, and the pressing component 200 is used to press against the battery 10 so that the battery 10 is fixed in the support frame 100.

[0024] like Figure 3 As shown, the support frame 100 is provided with a receiving cavity 110. Specifically, the support frame 100 is a hollow structure with a receiving cavity 110, and the receiving cavity 110 has an installation and removal port. The battery 10 can be installed in the receiving cavity 110 through the installation and removal port, and the battery 10 in the receiving cavity 110 can also be removed through the installation and removal port.

[0025] Combination Figure 2 and Figure 3 The pressing component 200 is disposed in the receiving cavity 110. When the battery 10 is placed in the receiving cavity 110, the pressing component 200 can press against the battery 10 to fix the battery 10.

[0026] Combination Figure 5 and Figure 7 Furthermore, the receiving cavity 110 has a first mounting wall 111, and a first terminal 1111 is provided on the first mounting wall 111; specifically, the first mounting wall 111 is a side wall of the receiving cavity 110, and the first terminal 1111 is disposed on the first mounting wall 111.

[0027] Combination Figure 5 and Figure 6 The pressing assembly 200 includes a pressing member 210 movably disposed within the receiving cavity 110, please refer to [the document for further details]. Figure 7 The pressing member 210 is disposed opposite to the first mounting wall 111. The pressing member 210 is configured to be able to approach or move away from the first mounting wall 111. Further, the pressing member 210 has a second mounting wall 211 disposed opposite to the first mounting wall 111. The second mounting wall 211 is provided with a second terminal 2111 disposed opposite to the first terminal 1111.

[0028] Understandably, when the pressing member 210 is operated to move toward the first mounting wall 111, the distance between the second mounting wall 211 and the first mounting wall 111 becomes closer and closer, and the distance between the second terminal 2111 and the first terminal 1111 also becomes closer and closer; when the pressing member 210 is operated to move away from the first mounting wall 111, the distance between the second mounting wall 211 and the first mounting wall 111 becomes farther and farther, and the distance between the second terminal 2111 and the first terminal 1111 also becomes farther and farther.

[0029] Furthermore, the pressing assembly 200 also includes an elastic member 220 connected to the pressing member 210. After elastic deformation, the elastic member 220 can apply an elastic force to the pressing member 210. Specifically, the elastic member 220 can provide an elastic force toward the first mounting wall 111 to the pressing member 210 after the pressing member 210 moves away from the initial position toward the first mounting wall 111.

[0030] Understandably, when the pressing member 210 is in its initial position, the distance between the first mounting wall 111 and the second mounting wall 211 is less than the length of the battery 10. During the process of installing the battery 10 into the receiving cavity 110, the pressing member 210 needs to be moved from its initial position away from the first mounting wall 111 so that the battery 10 can be placed between the first mounting wall 111 and the second mounting wall 211. After the battery 10 is placed between the first mounting wall 111 and the second mounting wall 211, the elastic member 220 can continuously apply an elastic force to the pressing member 210 so that the pressing member 210 can continuously hold the battery 10, thereby fixing the battery 10.

[0031] It should be noted that when the battery 10 is placed in the receiving cavity 110, one electrode of the battery 10 faces the first terminal 1111, and the other electrode faces the second terminal 2111. The battery 10 is held by the pressing member 210, and the positive and negative terminals of the battery 10 are held against the first terminal 1111 and the second terminal 2111, respectively. Both the first terminal 1111 and the second terminal 2111 are conductive components and are electrically connected to the connector 500 provided on the support frame 100. The connector 500 can be used to connect to the corresponding power-consuming body, thereby enabling the battery 10 to supply power to the power-consuming body.

[0032] When the battery 10 needs to be installed into the battery compartment of this application, one end of the battery 10 can be placed into the receiving cavity 110 through the installation and removal port of the receiving cavity 110, so that the electrode of that end of the battery 10 contacts the first terminal 1111. Then, the pressing member 210 is operated to gradually move away from the first mounting wall 111. During this process, the other end of the battery 10 is also placed into the receiving cavity 110 until the entire battery 10 is placed into the receiving cavity 110. Afterwards, under the action of the elastic member 220, the pressing member 210 can hold the battery 10, and make the electrode of the other end of the battery 10 contact the second terminal 2111. When the battery 10 needs to be removed from the battery compartment of this application, the pressing member 210 can be operated to move away from the first mounting wall 111 to separate the battery 10 from the second terminal 2111. Then the battery 10 can be easily removed from the receiving cavity 110. It is understood that when the battery 10 is installed in or removed from the battery compartment of this application, it can be quickly installed or removed without the aid of tools.

[0033] like Figure 6 As shown, the receiving cavity 110 also has a first abutting wall 112 disposed opposite to the first mounting wall 111. Specifically, the first abutting wall 112 and the first mounting wall 111 are the opposite side walls of the receiving cavity 110; as Figure 3 As shown, the pressing member 210 also has a second supporting wall 212 disposed opposite to the second mounting wall 211; combined with Figure 3 and Figure 6 The elastic element 220 is disposed between the first abutment wall 112 and the second abutment wall 212. Thus, when the pressing member 210 is operated to move away from the first mounting wall 111, the pressing member 210 will squeeze the elastic element 220 to cause the elastic element 220 to undergo compression deformation. After compression deformation, the elastic element 220 can apply an elastic force toward the first mounting wall 111 to the pressing member 210.

[0034] It should be noted that the elastic element 220 can be a spring, elastic rubber, or sheet, etc.

[0035] Combination Figure 4 and Figure 6 In some embodiments, the elastic element 220 is a spring; a first positioning post 1121 is provided on the first supporting wall 112, and one end of the spring is sleeved on the first positioning post 1121; a second positioning post 2121 is provided on the second supporting wall 212, and the other end of the spring is sleeved on the second positioning post 2121. The first positioning post 1121 and the second positioning post 2121 are used to position the two ends of the elastic element 220 respectively, reducing the risk of the elastic element 220 dislodging from its original position.

[0036] In some other embodiments, a first positioning post 1121 may be provided on the first abutting wall 112 instead of a second positioning post 2121 on the second abutting wall 212; in other embodiments, a second positioning post 2121 may be provided on the second abutting wall 212 instead of a first positioning post 1121 on the first abutting wall 112.

[0037] It is understood that in some other embodiments, the elastic member 220 may be connected between the first mounting wall 111 and the second mounting wall 211. When the pressing member 210 is moved away from the first mounting wall 111, the pressing member 210 will pull the elastic member 220 to cause the elastic member 220 to undergo tensile deformation. After undergoing compressive and tensile deformation, the elastic member 220 can apply an elastic force towards the first mounting wall 111 to the pressing member 210. It should be noted that in this embodiment, the elastic member 220 needs to avoid the placement position of the battery 10, thereby avoiding interference with the placement of the battery 10.

[0038] like Figure 2As shown, in some embodiments, the support frame 100 is further provided with a guide hole 1122 opposite to the first mounting wall 111. The guide hole 1122 penetrates the cavity wall of the receiving cavity 110 and the outer wall of the support frame 100. Specifically, the guide hole 1122 is formed in the first abutment wall 112 and penetrates the outer wall of the support frame 100. The battery compartment also includes an operating handle 300, which is slidably inserted through the guide hole 1122 and connected to the pressing member 210. Part of the structure of the operating handle 300 is exposed outside the support frame 100.

[0039] Understandably, a portion of the operating handle 300 protrudes outside the support frame 100. Therefore, personnel can hold the operating handle 300 protruding from the support frame 100 and operate it to move the pressure member 210 toward or away from the first mounting wall 111. The operating handle 300 facilitates operation, and the guide hole 1122 also guides the operating handle 300, reducing the risk of the pressure member 210 deviating.

[0040] Specifically, the operating handle 300 includes a connecting post 310 slidably passing through the guide hole 1122, and a pull part 320 connected to the connecting post 310 and located outside the support frame 100. The connecting post 310 is connected to the pressing member 210. It is understood that the connecting post 310 connects the pull part 320 and the pressing member 210, allowing personnel to adjust the position of the pressing member 210 by holding the pull part 320. Furthermore, the guide hole 1122 guides the connecting post 310, thereby guiding the movement of the pressing member 210 and reducing the risk of deviation of the pressing member 210.

[0041] Furthermore, the pressing member 210 has a connecting part 214 on the side away from the first mounting wall 111. In short, the connecting part 214 is connected to the second supporting wall 212, and the connecting part 214 has a threaded hole, and the connecting post 310 has a threaded section passing through the threaded hole.

[0042] It is understandable that the pressing member 210 can be installed in the receiving cavity 110 first, and then the connecting post 310 can be inserted into the receiving cavity 110 through the guide hole 1122, and the threaded section can be inserted into the threaded hole of the connecting post 310, so that the connecting post 310 and the connecting part 214 are threaded together.

[0043] like Figure 2 As shown, in some embodiments, the pressing member 210 is provided with a guide portion 213, and the cavity wall of the receiving cavity 110 is provided with a guide groove 120. The extending direction of the guide groove 120 is parallel to the arrangement direction of the first mounting wall 111 and the second mounting wall 211, and at least a portion of the guide portion 213 is slidably disposed in the guide groove 120.

[0044] It is understandable that the guide groove 120 is used to guide the movement of the guide part 213, thereby guiding the movement of the pressing part 210, thereby improving the movement accuracy of the pressing part 210 and reducing the risk of the pressing part 210 deviating from its movement path during movement.

[0045] Combination Figure 2 and Figure 3 In some embodiments, the battery compartment further includes a cover 400, which engages with the mounting / removing opening of the receiving cavity 110. In other words, the cover 400 has an open state and a closed state. When the cover 400 is in the open state, the mounting / removing opening is open; when the cover 400 is in the closed state, the mounting / removing opening is closed. The battery 10 can be installed or removed when the cover 400 is in the open state, and when the battery 10 is installed into the receiving cavity 110, switching the cover 400 to the closed state protects the battery 10.

[0046] Specifically, one side of the cover 400 is rotatably connected to the support frame 100. By flipping the cover 400, the cover 400 can be switched between an open state and a closed state.

[0047] Combination Figure 5 and Figure 7 More specifically, one side of the cover 400 has a pivot 430, the support frame 100 is provided with a pivot seat 130, the pivot seat 130 is provided with a shaft hole 131, the pivot 430 is rotatably inserted into the shaft hole 131, and the cover 400 is rotatably connected to the support frame 100 by means of the pivot 430.

[0048] Combination Figure 3 and Figure 6 Furthermore, the support frame 100 is provided with a first magnetic 140, and the cover 400 is provided with a second magnetic 440. The first magnetic 140 magnetically engages with the second magnetic 440 when the cover 400 seals the installation / removal opening of the receiving cavity 110. This reduces the risk of the cover 400 opening automatically. When it is necessary to install or remove the battery 10, applying external force to the cover 400 to overcome the attraction between the first magnetic 140 and the second magnetic 440 will open the cover 400.

[0049] Specifically, one of the first magnetic attractor 140 and the second magnetic attractor 440 is a magnet, and the other can be a magnet or an iron sheet.

[0050] like Figure 3As shown, in some embodiments, the cover 400 includes a transparent plate 410 and an outer frame 420 surrounding the transparent plate 410. The transparent plate 410 is positioned opposite to the mounting / removal opening of the receiving cavity 110 when the cover 400 seals the opening. It is understood that when the cover 400 is in the closed state, the transparent plate 410 is positioned opposite to the mounting / removal opening, allowing personnel to observe the state of the battery 10 inside the receiving cavity 110 through the transparent plate 410. The transparent plate 410 can be either fully transparent or semi-transparent.

[0051] This application also provides an electrical device, including the battery compartment and the power-consuming body of the above embodiments, wherein the power-consuming body is electrically connected to the battery compartment.

[0052] Specifically, the battery compartment is equipped with a connector 500, and the main power supply unit is equipped with an interface. The interface and the connector 500 can be connected by plugging in or by wires. In this way, the main power supply unit can be powered by the battery 10 in the battery compartment.

[0053] It should be noted that the electrical device can be a handheld vacuum cleaner, an electric toy, a portable testing instrument, etc.

[0054] When the battery 10 needs to be installed into the battery compartment of this application, one end of the battery 10 can be placed into the receiving cavity 110 through the installation and removal port of the receiving cavity 110, so that the electrode of that end of the battery 10 contacts the first terminal 1111. Then, the pressing member 210 is operated to gradually move away from the first mounting wall 111. During this process, the other end of the battery 10 is also placed into the receiving cavity 110 until the entire battery 10 is placed into the receiving cavity 110. Afterwards, under the action of the elastic member 220, the pressing member 210 can hold the battery 10, and make the electrode of the other end of the battery 10 contact the second terminal 2111. When the battery 10 needs to be removed from the battery compartment of this application, the pressing member 210 can be operated to move away from the first mounting wall 111 to separate the battery 10 from the second terminal 2111. Then the battery 10 can be easily removed from the receiving cavity 110. It is understood that the battery 10 can be installed in or removed from the battery compartment of this application without the aid of tools, and can be quickly installed and removed. The first terminal 1111 and the second terminal 2111 are both conductive components and are electrically connected to the connector 500 provided on the support frame 100. The connector 500 can be used to connect to the corresponding power-consuming body, so that the battery 10 can supply power to the power-consuming body.
