DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Embodiment: A USB power module with a replaceable cover, such as Figure 1-Figure 4 As shown, it includes a power module 1 and a cover module 2, the power module 1 includes a shell 101 and a first interface 102, the cover module 2 includes a connector 201, a connector 203 and a second interface 202, the connector 201 is snap-connected with the shell 101, the connector 201 is provided with a connector 203 matching the first interface 102, the connection between the connector 201 and the shell 101 and between the connector 203 and the first interface 102 are both of positive and negative symmetric design, the second interface 202 has three groups of different configurations, the second interface 202 is used to connect with electrical appliances, the power module can adapt to different types of electrical appliances as needed by replacing the cover modules 2 with different configurations, and a limit assembly is provided on the shell 101.

[0020] like Figure 4-Figure 6 As shown, the limit assembly includes a fixed block 3, a clamping block 4 and a driving assembly. Two fixed blocks 3 are fixedly connected to one side of the shell 101. The clamping block 4 is rotatably connected between the two fixed blocks 3 through a rotating shaft. A clamping groove 204 matching the clamping block 4 is opened on the joint 201. There are two clamping grooves 204, which are axially symmetrically arranged on the joint 201. Therefore, no matter whether the front or back side is selected to connect the joint 201 to the shell 101, it can match the clamping block 4 through two symmetrical clamping grooves 204. A driving assembly is provided on the same side of the shell 101 as the clamping block 4, and the driving assembly is used to drive the clamping block 4 to rotate.

[0021] like Figure 4-Figure 6 As shown, the driving assembly includes a slider 501, a slide plate 502, a ratchet bar 503, a ratchet 504, a torsion spring 505 and an elastic member 506. The slider 501 is slidably connected to the same side of the housing 101 as the clamping block 4. The two ends of the slider 501 are respectively fixedly connected to the slider 502 and the ratchet bar 503. The slider 502 is located on the outside of the housing 101, and the ratchet bar 503 is located on the inside of the housing 101. The ratchet 504 is fixedly connected to the rotating shaft of the clamping block 4, and the ratchet 504 is meshed with the ratchet bar 503. A torsion spring 505 is connected between the clamping block 4 and a fixed block 3, and an elastic member 506 is connected between the slider 501 and the housing 101.

[0022] When it is necessary to install the face cover module 2 and the power module 1, firstly, a translational external force is applied to the slide plate 502 to make it slide on the outside of the shell 101 through the slider 501, thereby driving the ratchet bar 503 to slide on the inside of the shell 101. Since the ratchet bar 503 is meshed with the ratchet wheel 504, the ratchet bar 503 will drive the ratchet wheel 504 to rotate, and then the ratchet wheel 504 will rotate the block 4 through the rotating shaft until the block 4 does not hinder the connection between the connector 201 and the shell 101. During this process, the torsion spring 505 and the elastic member 506 will be deformed, and then the connector 201 is aligned with the inside of the shell 101, and then it is directed to the shell. 101 slides inside until the connecting member 203 is stably connected to the first interface 102. At this time, the position of the slot 204 is opposite to the block 4. Then the external force applied to the slide plate 502 is released, and the slider 501 will drive the slide plate 502 and the ratchet bar 503 to move in the opposite direction and reset under the elastic action of the elastic member 506. Due to the characteristics of the ratchet bar 503 and the ratchet wheel 504, the movement of the ratchet bar 503 will not affect the ratchet wheel 504 at this time, and the block 4 rotates in the opposite direction to the inside of the slot 204 under the elastic action of the torsion spring 505. Therefore, through the cooperation between the block 4 and the slot 204, the connector 201 can be limited to prevent the connector 201 from being separated from the shell 101.

[0023] When it is necessary to remove the face cover module 2, it is only necessary to apply a translational external force on the slide plate 502 again, so that the slide plate 502 drives the slider 501 and the ratchet bar 503 to translate, thereby driving the block 4 to rotate through the ratchet 504, so that the block 4 is rotated away from the inside of the slot 204, and the block 4 no longer forms an obstacle to the connector 201. Then, the connector 201 is withdrawn from the inside of the shell 101 by sliding outward, thereby completing the disassembly of the face cover module 2.

[0024] like Figure 3 and Figure 4 As shown, the connector 201 further includes a positioning post 205 . Two pairs of positioning holes 103 are symmetrically formed on the power module 1 . The connector 201 is fixedly connected with the positioning post 205 that matches the positioning holes 103 .

[0025] When connecting the connector 201 and the housing 101, by preliminarily docking the positioning column 205 with the positioning hole 103 on the power module 1, the connector 201 and the housing 101 can be accurately aligned, and the connector 201 and the housing 101 can be kept firmly connected after the docking is completed.

[0026] like Figure 4 As shown, in order to facilitate the user to operate the slide plate 502, the slide plate 502 is provided with anti-slip grooves, which can increase the friction of the user during operation, prevent the hand from slipping, and ensure the accuracy of the operation.

[0027] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
