DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] An electronic device provided by the utility model is described in detail below in conjunction with embodiments.

[0025] See also Figure 1 , Figure 2 as well as Figure 3 , Figure 1 is a first cross-sectional schematic diagram of an embodiment of the electronic device of the present application; Figure 2 is a second cross-sectional schematic diagram of an embodiment of the electronic device of the present application; Figure 3 yes Figure 2 A structural diagram is shown. The present application provides an electronic device 10. The electronic device 10 can be any device, in which a battery 12 is installed. The electronic device 10 includes an electronic device body 1 and a mounting plate 2. The electronic device body 1 includes a shell 11, a battery 12 and a power-off bracket 13. The shell 11 is formed with a battery cavity 111. The battery cavity 111 is used to accommodate the battery 12. The battery 12 is placed in the battery cavity 111. The battery cavity 111 includes two inner side walls arranged opposite to each other. Both inner side walls are provided with an electrode connecting portion 1111.

[0026] The power-off bracket 13 is arranged in the shell 11. The power-off bracket 13 is a part of the electronic device 10 and can be used repeatedly. When the power-off bracket 13 includes one, an electrode connecting part 1111 and one end of the battery 12 are blocked or unblocked by the power-off bracket 13. Alternatively, another electrode connecting part 1111 and the other end of the battery 12 are blocked or unblocked by the power-off bracket 13. When the power-off bracket 13 includes two, an electrode connecting part 1111 and one end of the battery 12 are blocked or unblocked by the power-off bracket 13. Another electrode connecting part 1111 and the other end of the battery 12 are blocked or unblocked by the power-off bracket 13. Among them, the number of power-off brackets 13 and the position of the power-off bracket 13 between the electrode connecting part 1111 and the battery 12 can be determined according to actual needs and are not limited here.

[0027] When the power-off bracket 13 blocks the connection between the electrode connection part 1111 and the battery 12, the electrode connection part 1111 and the battery 12 are in contact with the power-off bracket 13 respectively, and the electronic device 10 is in a power-off state. When the power-off bracket 13 releases the blockage between the electrode connection part 1111 and the battery 12, the electrode connection part 1111 is in contact with the battery 12, and the electronic device 10 is in a power-on state.

[0028] The mounting plate 2 is used to be installed on a surface to be installed (not shown in the figure). The surface to be installed can be a wall (wall top, wall surface, etc.), a mounting pole, etc. The electronic device body 1 can be installed on the mounting plate 2. When the electronic device body 1 is installed on the mounting plate 2, the mounting plate 2 can act on the power-off bracket 13 to enable the power-off bracket 13 to release the connection between at least one electrode connecting portion 1111 and the battery 12. The electrode connecting portion 1111 is in contact with the battery 12, and the electronic device 10 is in a powered state.

[0029] Thus, the electronic device 10 uses the mechanical power-off method through the combined effect of the above-mentioned power-off bracket 13 and the mounting plate 2 to realize the power-on and power-off of the electronic device 10. When the electronic device body 1 is not installed on the mounting plate 2, the electronic device body 1 is in a power-off state, which is not only convenient for the transportation and storage of the electronic device 10, reduces the transportation risk of the electronic device 10, but also improves the transportation safety of the electronic device 10; and can reduce power consumption and increase the service life of the electronic device 10. In addition, the electronic device 10 is in a power-off state before it is installed and used, and the electronic device 10 is automatically powered on after it is installed and used, which makes the operation easier and simplifies the user's operation method. At the same time, as a component of the electronic device 10, the power-off bracket 13 is not easy to fall off and can be used repeatedly.

[0030] As in a specific embodiment, the electrode connection portion 1111 includes a positive connection portion 1111a and a negative connection portion 1111b. The connection between the positive connection portion 1111a and one end of the battery 12 is blocked or unblocked by the power-off bracket 13. And / or, the connection between the negative connection portion 1111b and the other end of the battery 12 is blocked or unblocked by the power-off bracket 13. As in the present embodiment, the power-off bracket 13 is located between the positive connection portion 1111a and one end of the battery 12. That is, the connection between the positive connection portion 1111a and one end of the battery 12 is blocked or unblocked by the power-off bracket 13. In other embodiments, when there are multiple batteries 12, the power-off bracket 13 may also be arranged between adjacent batteries 12.

[0031] In one embodiment, the power-off bracket 13 is liftably connected between the electrode connecting portion 1111 and the battery 12 along a first direction to block or unblock at least one electrode connecting portion 1111 from the battery 12. Specifically, the first direction may be, but is not limited to, a vertical direction. When the electronic device body 1 is mounted on the mounting plate 2, the mounting plate 2 acts on the power-off bracket 13, and the power-off bracket 13 moves upward in the vertical direction to unblock the electrode connecting portion 1111 from the battery 12, so that the electrode connecting portion 1111 and the battery 12 are in contact, and the electronic device 10 is in a powered-on state.

[0032] When the electronic device body 1 is removed from the mounting plate 2, the mounting plate 2 releases the force acting on the power-off bracket 13, and the power-off bracket 13 moves downward in the vertical direction to block the electrode connecting part 1111 and the battery 12. The electrode connecting part 1111 and the battery 12 are in a disconnected state, and the electronic device 10 is in a power-off state.

[0033] The power-off bracket 13 is liftably connected between the electrode connection part 1111 and the battery 12, and can realize powering on or off of the electronic device 10. At the same time, when the mounting plate 2 releases the force acting on the power-off bracket 13, the power-off bracket 13 can automatically restore to its original state and block the connection between the electrode connection part 1111 and the battery 12, further reducing the steps of powering off the electronic device 10.

[0034] See also Figure 4 , Figure 4 This is a schematic diagram of the structure of the power-off bracket in an embodiment of the electronic device of the present application. Figures 1 to 3Specifically, the power-off bracket 13 is provided with a contact portion 131 and a through portion 132. The contact portion 131 is located between the electrode connecting portion 1111 and the battery 12 and contacts between the electrode connecting portion 1111 and the battery 12. The contact portion 131 includes a first contact surface 1311 and a second contact surface 1312 that are arranged opposite to each other. When the mounting plate 2 does not act on the power-off bracket 13 or the mounting plate 2 releases the force acting on the power-off bracket 13, the electrode connecting portion 1111 abuts against the first contact surface 1311. The battery 12 abuts against the second contact surface 1312. The connection between the electrode connecting portion 1111 and the battery 12 is blocked by the contact portion 131, so that the electronic device 10 is powered off. Alternatively, when the mounting plate 2 acts on the power-off bracket 13, the contact portion 131 moves upward in the vertical direction, and the electrode connecting portion 1111 and the battery 12 are released from abutment with the contact portion 131 respectively. At this time, the battery 12 passes through the through portion 132 , and the battery 12 is connected to the electrode connecting portion 1111 , so that the electronic device 10 is powered on.

[0035] The contact portion 131 and the through portion 132 work together to put the electrode connection portion 1111 and the battery 12 in a blocked or unblocked state. The size of the through portion 132 is larger than the size of the end of the battery 12, so that the end of the battery 12 is connected to the electrode connection portion 1111, and the electronic device 10 is powered on. For example, the width of the through portion 132 of the power-off bracket 13 is larger than the outer diameter of the protruding portion of the positive electrode of the battery 12. Alternatively, the width of the through portion 132 of the power-off bracket 13 is larger than the outer diameter of the negative electrode of the battery 12.

[0036] During the process of installing the above-mentioned power-off bracket 13 to the shell 11, the first contact surface 1311 and the second contact surface 1312 in the contact part 131 can be coated with grease to make the lifting and lowering movement of the power-off bracket 13 along the first direction smoother, reduce the risk of the power-off bracket 13 getting stuck, and thereby increase the service life of the power-off bracket 13.

[0037] Furthermore, the second contact surface 1312 is tilted toward the battery 12. The width of the second contact surface 1312 at one end away from the mounting plate 2 is greater than the width of the second contact surface 1312 at one end close to the mounting plate 2. By limiting the second contact surface 1312 to be tilted, the smoothness of the movement of the power-off bracket 13 along the first direction is improved, the jamming phenomenon of the power-off bracket 13 is reduced, and the service life of the power-off bracket 13 is improved. In other embodiments, the first contact surface 1311 may also be tilted toward the electrode connecting portion 1111, so as to improve the smoothness of the movement of the power-off bracket 13 along the first direction, reduce the jamming phenomenon of the power-off bracket 13, and further improve the service life of the power-off bracket 13.

[0038] In actual practice, the electrode connecting portion 1111 may also be provided with a guide portion (not shown in the figure) to improve the smoothness of movement of the power-off bracket 13 along the first direction, reduce the occurrence of jamming of the power-off bracket 13, and further improve the service life of the power-off bracket 13.

[0039] In some embodiments, the power-off bracket 13 is an insulator (not shown in the figure). The insulator has a certain hardness and temperature resistance. Among them, the power-off bracket 13 adopts a product injection molding method of soft and hard rubber encapsulation, so that the power-off bracket 13 has the effects of wear resistance and high temperature resistance, improves the service life of the power-off bracket 13, and prevents the problem of high-voltage batteries 12 and high-power products causing high-temperature deformation and melting of moving parts. The contact portion 131 in the power-off bracket 13 can be made of high-temperature resistant material. High-temperature resistant materials can be but are not limited to polybutylene terephthalate (PBT) and polycarbonate (PC). The rest of the power-off bracket 13 except the contact portion 131 is made of silicone material. The hardness of silicone is greater than or equal to 70 degrees.

[0040] Please continue reading Figures 1 to 4 In one embodiment, the electronic device body 1 includes an elastic member 14. The elastic member 14 has a certain elastic force. The power-off bracket 13 is liftably connected between the electrode connecting portion 1111 and the battery 12 along a first direction through the elastic member 14. When the electronic device body 1 is installed on the mounting plate 2, the power-off bracket 13 moves upward in the vertical direction, and at the same time, the power-off bracket 13 acts on the elastic member 14, and the elastic member 14 is compressed. When the mounting plate 2 releases the force on the power-off bracket 13, the elastic member 14 returns to its original state and acts on the power-off bracket 13, and the power-off bracket 13 moves downward in the vertical direction to block the connection between the electrode connecting portion 1111 and the battery 12, thereby powering off the electronic device 10.

[0041] By providing the elastic member 14 on the electronic device body 1, the power-off bracket 13 can automatically block the connection between the electrode connection part 1111 and the battery 12, realize automatic movement, and reduce the power-off steps of the electronic device 10. The elastic member 14 can be a spring.

[0042] The elastic member 14 can be arranged on the power-off bracket 13 or the housing 11. In a specific embodiment, the power-off bracket 13 includes a first end 13a. The first end 13a of the power-off bracket 13 is arranged away from the mounting plate 2. The elastic member 14 is arranged between the first end 13a and the top of the housing 11. By limiting the setting position of the elastic member 14, the elastic member 14 is more likely to restore its original state and act on the power-off bracket 13, so that the power-off bracket 13 automatically blocks the connection between the electrode connecting part 1111 and the battery 12, thereby reducing the power-off steps of the electronic device 10.

[0043] Furthermore, the electronic device body 1 includes two elastic members 14. The first end 13a includes two elastic mounting portions 133 symmetrically arranged. The elastic member 14 is arranged between the elastic mounting portion 133 and the housing 11. One elastic member 14 is arranged between one elastic mounting portion 133 and the top of the housing 11. Another elastic member 14 is arranged between another elastic mounting portion 133 and the top of the housing 11. Through the two elastic members 14 and the two elastic mounting portions 133, the stability of the lifting movement of the power-off bracket 13 along the first direction is achieved, which is more conducive to powering on or off the electronic device 10.

[0044] Furthermore, a positioning column 112 is provided on the inner wall of the shell 11. The elastic member 14 is sleeved on the positioning column 112. The positioning column 112 can limit the compression direction of the elastic member 14 along the first direction, thereby reducing the risk of the elastic member 14 moving offset. Optionally, the elastic mounting portion 133 is provided with a first elastic mounting groove (not shown in the figure). One end of the elastic member 14 is located in the first elastic mounting groove. The first elastic mounting groove is used to assemble one end of the elastic member 14 to improve the stability of the elastic member 14 moving along the first direction. In addition, a second elastic mounting groove (not shown in the figure) is provided on the inner wall of the shell 11. The other end of the elastic member 14 is located in the second elastic mounting groove. The second elastic mounting groove is used to assemble the other end of the elastic member 14 to improve the stability of the elastic member 14 moving along the first direction.

[0045] It should be noted that the compression distance of the elastic member 14 is greater than the separation distance between the power-off bracket 13 and the battery 12. At the same time, the compression distance of the elastic member 14 is greater than the interference distance between the power-off bracket 13 and the mounting plate 2. By limiting the above distance, the stability of the electronic device body 1 installed on the mounting plate 2 is improved.

[0046] Please continue reading Figures 1 to 4 In one embodiment, a step portion 21 is provided on one side of the mounting plate 2 facing the electronic device body 1. When the electronic device body 1 is mounted on the mounting plate 2, the mounting plate 2 acts on the power-off bracket 13, and the power-off bracket 13 can slide to the step portion 21 to release the blockage between the electrode connecting portion 1111 and the battery 12. By providing the step portion 21 on the mounting plate 2, the power-off bracket 13 can be stably moved up and down along the first direction, the smoothness of the movement of the power-off bracket 13 along the first direction is improved, and the occurrence of the power-off bracket 13 getting stuck is reduced. The above-mentioned step portion 21 is connected to the mounting plate 2 in a fixed or detachable manner. The specific structure of the step portion 21 is not limited.

[0047] Specifically, a step slope 211 is provided at one end of the step portion 21. The step slope 211 is arranged toward the installation direction of the electronic device body 1. By providing the step slope 211 on the step portion 21, it is convenient for the power-off bracket 13 to stably move up and down along the first direction, reduce friction resistance, and reduce the occurrence of the power-off bracket 13 getting stuck. Among them, the electronic device body 1 is mounted on the mounting plate 2 in a sliding manner, so that the power-off bracket 13 can slide from the step slope 211 to the step portion 21. In other embodiments, a limiting portion (not shown in the figure) is provided on the periphery of the mounting plate 2 or the electronic device body 1. The further movement of the power-off bracket 13 is limited by the limiting portion. The structure and setting position of the limiting portion can be determined according to actual conditions and are not limited here.

[0048] In one embodiment, the power-off bracket 13 includes a second end 13b. The second end 13b of the power-off bracket 13 is arranged opposite to the first end 13a of the power-off bracket 13. The end of the second end 13b is arranged in a spherical shape, which reduces the friction resistance of the second end 13b of the power-off bracket 13 moving along the step portion 21, thereby reducing the occurrence of the power-off bracket 13 getting stuck.

[0049] In one embodiment, the electronic device 10 may be, but is not limited to, a fire fighting device, such as an automatic fire alarm system.

[0050] In one embodiment, the electronic device 10 includes a mechanical power-off detection component (not shown in the figure). The electronic device 10 is provided with a power-off detection indicator light (not shown in the figure). During the operation of the electronic device 10, the mechanical power-off detection component can detect whether the power-off bracket 13 blocks or unblocks the electrode connecting portion 1111 and the battery 12. When the mechanical power-off detection component detects that an abnormality occurs when the electronic device 10 is powered on or off, the mechanical power-off detection component sends a signal to the power-off detection indicator light. The power-off detection indicator light displays whether the electronic device 10 is abnormal, and it is also convenient for disassembly inspection and replacement of parts. Therefore, by monitoring the operation process of the electronic device 10 through the mechanical power-off detection component, it can not only ensure the normal use of the electronic device 10, but also facilitate subsequent maintenance and replacement of parts, thereby extending the service life of the electronic device 10.

[0051] Compared with the prior art, the electronic device includes an electronic device body and a mounting plate. The electronic device body includes a housing, a battery and a power-off bracket. The housing forms a battery cavity. The two inner side walls of the battery cavity are arranged opposite to each other and are provided with electrode connecting parts. The battery is placed in the battery cavity. The power-off bracket is arranged in the housing. The electronic device body is mounted on the mounting plate, and the mounting plate can act on the power-off bracket so that the power-off bracket can release the connection between at least one electrode connecting part and the battery. The electrode connecting part is in contact with the battery, and the electronic device is in a powered-on state. Thus, the electronic device is powered on and off by the mechanical power-off method through the combined action of the power-off bracket and the mounting plate. When the electronic device body is not mounted on the mounting plate, the electronic device body is in a power-off state, which is not only convenient for the transportation and storage of the electronic device, but also reduces the risk of electronic device transportation and improves the safety of electronic device transportation; and can reduce power consumption and improve the service life of the electronic device. In addition, the electronic device is in a power-off state before it is installed and used, and the electronic device is powered on automatically after it is installed and used, which is more convenient to operate and simplifies the user's operation method. At the same time, as a component of an electronic device, the power-off bracket is not easy to fall and can be used repeatedly.
