[0026] The following is a detailed description of non-limiting implementation schemes of the present invention in conjunction with the accompanying drawings.

[0027] As attached Figure 1 , is a schematic diagram of the overall structure of the power supply 23 device in the embodiment of the utility model; as shown in the attached Figure 2 As shown, it is a schematic diagram of the structure of the power supply 23 component 2 in the embodiment of the utility model Figure 1 ; as attached Figure 3 As shown, it is a schematic diagram of the structure of the power supply 23 component 2 in the embodiment of the utility model Figure 2 Attached Figure 2 and attached Figure 3 The drawings are drawings of the power supply 23 assembly 2 at different viewing angles. As can be seen from the drawings, the power supply 23 device includes a front housing assembly 1 and a power supply 23 assembly 2.

[0028] The front shell assembly 1 includes a first shell 11 and a second shell 12 connected to each other. The first shell 11 and the second shell 12 are arranged at a right angle, so that a larger shielding space can be formed.

[0029] The power supply 23 assembly 2 includes a third housing 21 and a fourth housing 22 connected to each other, and a power supply 23. The third housing 21 and the fourth housing 22 are arranged at right angles. The third housing 21 is connected to the second housing 12. The side of the fourth housing 22 facing away from the third housing 21 is close to the first housing 11. The first housing 11, the second housing 12, the third housing 21 and the fourth housing 22 form a cavity 3. The power supply 23 is arranged in the cavity 3, and the power supply 23 is arranged in the fourth housing 22, and the fourth housing 22 is arranged vertically. The power supply 23 is in the cavity 3 and can be shielded by the first housing 11, the second housing 12, the third housing 21 and the fourth housing 22, so as to be protected. The power supply 23 can be a battery, a capacitor, a voltage converter and a current converter, etc. On the one hand, the cavity 3 formed by the housing to protect the power supply 23 can prevent the power supply 23 from being interfered with by other components. On the other hand, the fourth housing 22 is arranged vertically, so that the power supply 23 is arranged vertically, which can further avoid the risk of short circuit caused by the parts inside the device falling on the power supply 23. Moreover, the power supply 23 device of the present invention is configured in this way, which can solve the problem that a protective cover is added to the outside of the power supply 23, thereby increasing the manufacturing cost and making the assembly process complicated.

[0030] In some embodiments, as shown in the attached Figure 3 As shown, a safety distance 4 is provided between the power supply 23 and the first housing 11, the third housing 21, and the fourth housing 22. Since the power supply 23 generates heat when in use, the safety distance 4 facilitates the heat dissipation of the power supply 23. When the housing is too close to the power supply 23, the heat of the power supply 23 is too high and is easily transferred to the housing, and the safety distance 4 can avoid this problem.

[0031] In some embodiments, as shown in the attached Figure 2-3 As shown, the fourth housing 22 is provided with a support column 221, the support column 221 is provided with a first connection hole, the power supply 23 is provided with a second connection hole, and the first connection hole and the second connection hole are connected by a fastener. The support column 221 is used to separate the power supply 23 from the fourth housing 22, and the power supply 23 can be connected to the fourth housing 22. Specifically, one end of the support column 221 is connected to the fourth housing 22, and the other end is connected to the power supply 23. In this way, the length of the support column 221 is the safety distance 4 between the fourth housing 22 and the power supply 23. The safety distance 4 can be set according to actual conditions, and no restriction is made here.

[0032] In some embodiments, as shown in the attached Figure 2As shown, the power supply 23 is square, which can be understood as the power supply 23 is roughly square, and the shape close to the square is also within the scope of the square of the utility model. And avoidance grooves 231 are provided on the four corners of the power supply 23, and the second connection hole is arranged in the avoidance groove 231. There are four support columns 221, and the position of the support column 221 corresponds to the position of the second connection hole. There are four support columns 221, which can be stably connected to the power supply 23. The avoidance groove 231 facilitates the installation of fasteners. Fasteners include screws, bolts, studs and nuts. Exemplarily, the fasteners include screws and nuts, the fasteners pass through the avoidance groove 231, and one end of the fasteners passes through the first connection hole and the second connection hole, and is connected to the nut outside the fourth shell 22.

[0033] In some embodiments, as shown in the attached Figure 2-3 As shown, the third housing 21 is provided with a first connection portion 211 on a side facing away from the fourth housing 22, and the first connection portion 211 is connected to the second housing 12 through a fastener. Similarly, both the first connection portion 211 and the second housing 12 are provided with screw holes, and screws, bolts or studs are passed through the screw holes of the first connection portion 211 and the second housing 12, and connected to nuts outside the second housing 12, so as to connect the first connection portion 211 and the second housing 12.

[0034] In some embodiments, in order to stabilize the connection between the third housing 21 and the second housing 12, the third housing 21 is provided with a second connection portion 212, which is disposed on the side of the third housing 21 facing away from the fourth housing 22. Compared with the first connection portion 211, the second connection portion 212 is closer to the fourth housing 22. The third housing 21 is provided with a connection column, which extends toward the fourth housing 22 to be connected to the second connection portion 212. The connection column can be connected to the second connection portion 212 through a snap-fit ​​structure, or can be connected to the second connection portion 212 through a fastener.

[0035] In some embodiments, a baffle 222 is disposed on one side of the fourth housing 22 close to the first housing 11, and the baffle 222 is parallel to the first housing 11. The baffle 222 is used to block the upper side of the power source 23 to protect the power source 23.

[0036] In some embodiments, a gap is provided between the baffle 222 and the first housing 11, and a safety gap is provided between the baffle 222 and the power source 23. The gap facilitates the communication between the cavity 3 and the external air. If the power source 23 generates heat and causes the temperature of the cavity 3 to be high, the air in the cavity 3 can circulate with the external air through the gap to cool the cavity 3 and / or the power source 23.

[0037] In some embodiments, the power supply 23 device is provided with a speaker assembly 5, which is connected to the power supply 23, disposed in the third housing 21, and located in the cavity 3. The speaker assembly 5 is used to remind the working status of the power supply 23, or remind the working status of the device using the power supply 23 device.
