Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a hidden power supply device for seats. Background Art

[0002] In order to improve the aesthetics of the chair and expand its functionality, various electrical appliances are often added to existing chairs. Especially in the field of e-sports, some gaming chairs currently on the market will add ambient light strips to the back bracket to create an immersive ambient lighting effect, set up a fan in the lumbar support to provide heat dissipation for the user's back, set up a portable monitor on the armrest to provide additional information processing space for the user, and so on. While adding these electrical appliances to expand the functionality and beautify the gaming chair, it also brings power supply requirements to the gaming chair. Most gaming chairs are connected to the power supply directly through the computer case or socket via a power cord. However, the length of the power cord not only limits the movement space of the gaming chair, but also easily scratches or even crushes the power cord during the movement of the gaming chair, posing a risk of leakage and poor safety.

[0003] In order to solve the above problems, the existing patent provides a luminous colorful gaming chair (application number: CN201920749229.3). A power supply slot is set on the back of the chair, and the power connector is set in the power supply slot, so that the user can put a smaller power bank into the power supply slot and connect the power connector to power the gaming chair. The power bank moves with the gaming chair, which not only does not restrict the movement of the gaming chair, but also makes the power bank and the power connector less likely to be damaged, and has higher safety.

[0004] However, the above solution has the following problems: the power supply slot is recessed on the rear side of the chair back, so after the power bank is installed in the power supply slot, the power bank and the power connector connected to the power bank will be exposed on the outer surface of the chair back. The power bank has a sense of abruptness compared to the chair back, making the chair back less integrated in appearance and less aesthetically pleasing. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a seat power supply device, in which the mobile power supply is located between the lumbar support and the back support after installation, and there is no need to groove the back support, thereby ensuring the integrity of the seat appearance; and the front and rear end surfaces of the mobile power supply are blocked by the lumbar support and the back support, so that the mobile power supply is not easily exposed, thereby improving the aesthetics of the seat.

[0006] The effect of the utility model is achieved in this way:

[0007] The present application provides a seat power supply device, including a back support, a lumbar support and a mobile power supply. The rear end of the lumbar support protrudes to form a connecting portion, and the lumbar support is connected to the front end of the back support through the connecting portion; the connecting portion is a hollow structure, and the hollow part thereof forms a power supply mounting portion. The upper end of the connecting portion is hollowed out to provide a mounting port, and the mounting port is connected to the power supply mounting portion. The mobile power supply is inserted into the power supply mounting portion through the mounting port, so that the mobile power supply is connected to the connecting portion. The mobile power supply is configured to power the seat.

[0008] Furthermore, the connecting portion includes an upper connecting portion and a lower connecting portion spaced apart from each other. The space between the upper and lower connecting portions forms the power supply mounting portion, and the mounting opening is hollowed out in the upper connecting portion. This ensures that after the power bank is inserted through the mounting opening, the left and right sides of the power bank are not blocked by other objects, allowing the user to directly access the power bank through the openings on the left and right sides of the power bank mounting portion, making it easy for the user to remove and replace the power bank.

[0009] Furthermore, an elastic member is installed at the rear end of the lumbar support, directly opposite the power supply mounting portion. This elastic member is configured to press the power bank tightly against the mounting portion. This strengthens the connection between the power bank and the lumbar support, preventing the power bank from swaying or even falling out of the mounting portion due to external forces when the seat is moved or the backrest is adjusted in pitch.

[0010] Furthermore, at least one of the left and right side walls of the connecting portion is provided with a socket, which is configured to connect to a data cable of a mobile power supply and transmit current to the seat. By providing the socket on the side wall of the connecting portion, after the mobile power supply is installed in the power supply mounting portion, the data cable of the mobile power supply can be easily connected to the lumbar support.

[0011] Furthermore, at least one of the left and right side walls of the connecting portion is recessed to form a hidden portion, and the socket is disposed within the hidden portion. When the data cable of the mobile power supply is connected to the socket, the interface of the data cable is buried in the hidden portion and is not easily exposed, thereby further improving the aesthetics of the seat.

[0012] Furthermore, a wiring opening is provided at the rear end of the connecting portion, which is configured to allow the wiring of the back support to pass through and be electrically connected to the socket. The rear end of the connecting portion is closely attached to the back support, making the wiring inside the back support less likely to be exposed, further improving the overall appearance and aesthetics of the seat.

[0013] The seat power supply device provided in the present application connects the mobile power supply to the connecting part so that the mobile power supply is located between the lumbar support and the back support after installation, without the need to groove the back support, thereby ensuring the integrity of the seat appearance; and the front and rear end surfaces of the mobile power supply are blocked by the lumbar support and the back support, so that the mobile power supply is not easily exposed, and does not feel abrupt compared to the back of the chair, thereby improving the aesthetics of the seat.
