[0053] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] Example

[0055] Figure 1 This is a schematic diagram of the structure of vehicle 1 in one embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the power supply system 2 in the illustrated embodiment; Figure 3 for Figure 1 A perspective view of the power supply structure 100 in the illustrated embodiment; Figure 4 for Figure 1 An exploded view of the power supply structure 100 in the illustrated embodiment.

[0056] See Figure 1 This application provides a vehicle 1, which includes a power supply system 2.

[0057] See Figures 2 to 4This embodiment provides a power supply system 2, including a power supply structure 100, an electrical appliance 200, and multiple second wiring harnesses 300. The power supply structure 100 includes a rotating base 10 and two bases 20, which are respectively a first base 20a and a second base 20b. The electrical appliance 200 includes an appliance body 201 and multiple first wiring harnesses 202, which are connected to multiple loops 21 of the first base 20a (see...). Figure 4 Each of the first wire harness 202 and the second wire harness 201 is electrically connected to the first wire harness 202. The second wire harness 201 is connected to the rotating base 10 and can rotate relative to the first wire harness 202. The multiple second wire harnesses 300 correspond one-to-one with the multiple rings 21 of the second base 20b and are electrically connected to each other.

[0058] Thus, the appliance 200 is electrically connected to the first base 20a via the first wiring harness 202, the first base 20a is electrically connected to the second base 20b via the rotating seat 10, and the second base 20b can be connected to other devices via the second wiring harness 300, thereby forming a circuit. The appliance body 201 of the appliance 200 is connected to the rotating seat 10 so that when the appliance body 201 rotates relative to the first wiring harness 202, the appliance body 201 drives the rotating seat 10 to rotate relative to the two bases 20.

[0059] In this embodiment, the electrical appliance 200 can be a vehicle-mounted screen, the first wiring harness 202 can be the wiring harness of the vehicle-mounted screen, and the second wiring harness 300 can be the wiring harness of the vehicle 1, forming a circuit to realize the various functions of the vehicle-mounted screen. The electrical appliance body 201 can be the screen body of the vehicle-mounted screen, and the screen body is connected to the rotating seat 10. When in use, the screen body can rotate according to the user's instructions.

[0060] In other embodiments, the appliance 200 may also be an appliance with other rotatable parts.

[0061] Figure 5 for Figure 1 A cross-sectional view of the power supply structure 100 in the illustrated embodiment; Figure 6 for Figure 1 Exploded view of the power supply structure 100 in the illustrated embodiment; Figure 7 for Figure 1 A schematic diagram of the slip ring structure 11 in the embodiment shown.

[0062] See Figures 5 to 7This embodiment provides a power supply structure 100, including a rotating base 10, two bases 20, and multiple contact groups 30. The rotating base 10 includes two axially spaced slip ring structures 11, each slip ring structure 11 including multiple slip rings 111. These slip rings 111 are radially spaced apart, and the slip rings 111 of one slip ring structure 11 are electrically connected one-to-one with the slip rings 111 of the other slip ring structure 11. The two bases 20 are respectively located at the axial ends of the rotating base 10. Each base 20 includes multiple rings 21, which are radially spaced apart and correspond one-to-one with each slip ring 111. The multiple contact groups 30 correspond one-to-one with each slip ring 111. Each contact group 30 includes multiple contacts 31 circumferentially spaced apart. Each contact group 30 is disposed on one of the corresponding slip rings 111 and rings 21, allowing slidable contact with the other.

[0063] The aforementioned power supply structure 100, by providing a contact 31 between the corresponding slip ring 111 and ring 21, allows the slip ring 111 and ring 21 to slidably contact each other through the contact 31. This enables an electrical connection to be formed between the rotating seat 10 and the base 20 when the rotating seat 10 rotates relative to the two bases 20, and eliminates the need for a wiring harness between the rotating seat 10 and the base 20, thereby improving the stability of the electrical connection when the rotating seat 10 rotates. For example, the rotatable part of the appliance 200 can be connected to the rotating seat 10, and the appliance 200 can be powered through the power supply structure 100, thus improving the stability of the electrical connection of the appliance 200.

[0064] For example, when the appliance 200 is a vehicle screen, the rotatable screen body can be connected to the rotating base 10. It should be noted that a power supply system is provided in related technologies, which directly connects the wiring harness to the rear of the screen body. This causes the wiring harness to swing with the screen body when it rotates, easily leading to tension or wear on the wiring harness, resulting in problems such as screen flickering, distorted display, or black screen. However, in the power supply structure 100 of the above embodiment, since there is no wiring harness connection between the rotating base 10 and the base 20, when the rotating base 10 rotates with the screen body, the first wiring harness 202 and the second wiring harness 300 do not rotate, thereby reducing the risk of wear on the first wiring harness 202 or the second wiring harness 300 and ensuring normal display function of the screen body. Furthermore, since the contact group 30 includes multiple contacts 31 spaced circumferentially, each ring 21 and its corresponding slip ring 111 are electrically conductive through the multiple contacts 31, ensuring excellent conductivity and avoiding poor contact. Optionally, multiple contacts 31 of the same contact group 30 are evenly spaced along the circumference. The contact group 30 includes 8 to 10 contacts 31.

[0065] It is understood that each ring 21 forms a conductive circuit with the corresponding contact group 30 and slip ring 111, therefore the multiple rings 21 of the base 20 correspond one-to-one with multiple conductive circuits. The multiple rings 21 and the multiple slip rings 111 are coaxially arranged. Optionally, the contacts 31, rings 21, and slip rings 111 are all made of metal (such as copper alloy). In this embodiment, the contacts 31 are disposed on the rings 21, and the side of the slip ring 111 facing the rings 21 has a smooth and flat surface, so that the rotating seat 10 can rotate smoothly relative to the base 20 and ensure good electrical conductivity between the contacts 31 and the slip rings 111.

[0066] In some embodiments, such as Figure 5 As shown, the base 20 includes a first sleeve 22, with a plurality of rings 21 passing through the end of the first sleeve 22 near the rotating seat 10. The power supply structure 100 also includes a plurality of first transmission elements 40, which pass through the end of the first sleeve 22 away from the rotating seat 10, and the plurality of first transmission elements 40 correspond one-to-one with the plurality of rings 21 and are electrically connected to each other. In this way, the rings 21 can be electrically connected to the wiring harnesses of other devices through the first transmission elements 40, thereby forming a circuit.

[0067] Figure 8 for Figure 1 A schematic diagram of the assembly state of the base 20, the first transmission component 40, and the connector 50 in the illustrated embodiment.

[0068] In some embodiments, such as Figure 6 and Figure 8 As shown, the power supply structure 100 also includes two connectors 50, which are respectively plugged into the ends of the two first sleeves 22 away from the rotating base 10. The end of the first transmission member 40 away from the ring 21 passes through the connector 50, so that the wiring harness of other devices can be connected to the connector 50 through terminals. Since the base 20, the first transmission member 40 and the connector 50 can all remain relatively stationary when the rotating base 10 rotates, damage to the connector 50 and the first transmission member 40 due to force can be avoided.

[0069] In some embodiments, the first transmission element 40 includes a wire harness or functional pins for transmitting electrical energy and / or electrical signals.

[0070] In some embodiments, such as Figure 8 As shown, the base 20 also includes a first mounting portion 23, which is connected to the outer periphery of the first sleeve 22 to facilitate the mounting and fixing of the base 20. For example, a second base 20b (see...) can be used... Figure 4 The first mounting portion 23 of the first base 20a is connected to the dashboard frame of the vehicle 1, and the first mounting portion 23 of the first base 20a is connected to the housing of the vehicle screen. Optionally, the first mounting portion 23 is connected to other components by fasteners.

[0071] In some embodiments, such as Figure 5 As shown, the rotating base 10 also includes a second sleeve 12, which is sleeved around the two slip ring structures 11. Two first sleeves 22 are respectively fitted to the two ends of the second sleeve 12 and can rotate relative to it. Thus, by providing the second sleeve 12, the end of the first sleeve 22 with the ring 21 is confined within the second sleeve 12, ensuring stable contact between the ring 21 and the slip ring 111 through the contact point 31, thereby further improving electrical conductivity. Optionally, the second sleeve 12 is welded to the two slip ring structures 11 respectively.

[0072] In some embodiments, such as Figure 3 As shown, the rotating base 10 also includes a second mounting portion 13, which is connected to the outer periphery of the second sleeve 12 to facilitate the mounting and fixing of the rotating base 10. Optionally, the second mounting portion 13 can be connected to other devices via fasteners. In use, the second mounting portion 13 can be connected to a rotatable part of the electrical appliance 200, such as the screen body of a vehicle screen.

[0073] In some embodiments, combined with Figure 6 and Figure 7 As shown, the power supply structure 100 also includes a plurality of second transmission components 60, which are electrically connected between the plurality of slip rings 111 of the two slip ring structures 11 to transmit electrical energy and / or electrical signals. In use, the rotatable part of the appliance 200 is connected to the second sleeve 12 and can drive the second sleeve 12, the two slip ring structures 11 and the second transmission components 60 to rotate together. Since there is no relative rotation between the second transmission components 60 and the slip ring structures 11, the conductive connection between the two slip ring structures 11 is reliable.

[0074] The power supply structure 100 provided in this embodiment eliminates the problem of the wiring harness and terminals swinging when the part of the electrical appliance 200 rotates, avoids the terminals or wiring harness being subjected to force and wear from contact with other parts, ensures good electrical connection, and ensures that the electrical appliance 200 functions normally. For example, it avoids the screen flickering, distorted screen or black screen caused by the screen body of the vehicle screen being able to rotate.

[0075] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
