It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the front and rear associated objects are in an "or" relationship.

[0036] The suction cup assembly, battery module and terminal device provided by the embodiments of the present application will be described in detail below in conjunction with the drawings, specific embodiments and application scenarios.

[0037] As shown in the drawings, Figures 1 to 6 The present application provides a suction cup assembly, which comprises a suction cup 100 and a blocking piece 200. In the thickness direction of the suction cup 100, the suction cup 100 has a first face 110 and a second face 120 arranged oppositely. The first face 110 is provided with a vent hole 111 for adsorbing a battery 300, so that the battery 300 is detachably connected with the suction cup 100. The second face 120 is used for connecting with a device main body 400 of a terminal device. The suction cup 100 is internally provided with a gas guide channel 130, which is in communication with the vent hole 111. Part of the blocking piece 200 is arranged in the gas guide channel 130. The blocking piece 200 is movable relative to the gas guide channel 130, so as to cut off or conduct the gas path of the gas guide channel 130. When it is needed to cut off the gas path of the gas guide channel 130, the blocking piece 200 is moved to block the gas guide channel 130. When it is needed to conduct the gas path of the gas guide channel 130, the blocking piece 200 is moved reversely to make the internal and external air pressures of the gas guide channel 130 equal.

[0038] In the embodiments of the present application, when it is needed to install the battery 300 on the device main body 100 of the terminal device, the gas path of the gas guide channel 130 of the suction cup 100 is first conducted. The battery 300 is placed on the suction cup 100 and slightly pressed, so that the gas in the gas guide channel 130 is discharged through the exhaust port of the gas guide channel 130. Then, the blocking piece 200 is driven to move relative to the gas guide channel 130, so as to block the exhaust port of the gas guide channel 130, thereby cutting off the gas path of the gas guide channel 130 and making the inside of the gas guide channel 130 in a negative pressure state, so that the battery 300 is adsorbed by the suction cup 100. When it is needed to detach the battery 300 from the device main body 100, the blocking piece 200 is moved to conduct the gas path of the gas guide channel 130, so that the internal and external air pressures of the gas guide channel 130 are equal, thereby separating the battery 300 from the suction cup 100. Therefore, the embodiments of the present application can solve the problem that the battery 300 of the terminal device cannot be detached.

[0039] Optionally, the number of the air holes 111 is multiple, each of the air holes 111 is in communication with the air guide channel 130, and each of the air holes 111 is arranged in sequence along the extension direction of the air guide channel 130, thereby improving the stability of the suction cup 100 in adsorbing the battery 300.

[0041] Specifically, when it is needed to cut off the air path of the air guide channel 130, the plugging piece 200 is inserted into the sealing section 132 to make the sealing cooperation therebetween, so as to plug the air guide section 131 and cut off the air path of the air guide channel 130; when it is needed to conduct the air path of the air guide channel 130, the plugging piece 200 is moved to disengage the plugging piece 200 from the sealing section 132, so as to conduct the air path of the air guide channel 130 and make the internal and external air pressures of the air guide channel 130 equal.

Of course, the limiting section 133 can not be arranged, in which case the end with the greater width of the sealing section 132 forms the exhaust port of the air guide channel 130.

In this scheme, the provision of the gas conveying section 135 makes a certain distance exist between the limiting section 133 and the edge of the suction cup 100, which is beneficial to improve the structural strength of the limiting section 133, thereby improving the service life of the suction cup 100. Of course, the gas conveying section 135 can also not be provided.

In addition, the suction plate 140 is a deformation piece, which can avoid the aluminum plastic film on the surface of the battery 300 being scratched, thereby protecting the battery 300.
