Technical Field

[0001] This application relates to the field of seating technology, specifically to a seat back panel structure and a seat. Background Technology

[0002] In seat design, map pockets serve as important storage space. Commonly used map pockets include hard-sided map pockets, mesh map pockets, and cover-sewn map pockets. These map pockets have significant drawbacks in low-light environments; when users need to find small items such as keys or cards inside, insufficient lighting often leads to difficulties in operation.

[0003] In existing technologies, a smart lighting map bag structure combining infrared sensing and photosensitive sensing is used. An MCU controller monitors ambient light and usage status in real time, automatically controlling the operation of LED lighting elements. However, this structure requires complex control circuitry, including multiple electronic components such as infrared sensors, photoresistors, and microprocessors, resulting in structural complexity. Furthermore, the use of multiple sets of electronic components significantly increases production costs. Utility Model Content

One end of the third wire is connected to the second terminal block, and the other end of the third wire is connected to the plug.

[0017] When the magnetic component approaches the magnetic switch, the first spring separates from the second spring, and the first wire disconnects from the second wire.

[0018] When the magnetic component moves away from the magnetic switch, the first spring contacts the second spring, and the first wire and the second wire become conductive.

Detailed Implementation

[0040] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0041] refer to Figures 1-4 This application provides a seat back panel structure, including a back panel 100, a light module 200, and a map pocket 300.

[0042] The backplate 100 serves as the basic structure for supporting and securing other components. It can be manufactured through injection molding, metal stamping, or other suitable processing methods, such as using high-strength plastics or aluminum alloys, to meet the requirements of mechanical strength and lightweighting. The light source 210 can be implemented using LED chips, halogen bulbs, or other devices capable of providing a light source. The magnetic switch 220 can be implemented using a reed switch, Hall effect sensor, or other switching element capable of responding to changes in a magnetic field, thereby controlling the circuit's on / off state through changes in the magnetic field.

[0043] The lamp module 200 is mounted on the back panel 100. The lamp module 200 includes a light lamp 210 and a magnetic switch 220. The magnetic switch 220 is electrically connected to the light lamp 210 and forms a normally closed magnetic trigger circuit to control the light lamp 210 to turn on and off.

[0044] The map pocket 300 is movably connected to the back panel 100, forming a storage space 400. The map pocket 300 is equipped with a magnetic component 500. The movable connection of the map pocket 300 can be achieved through hinges, slide rails, or flexible connectors. For example, a cloth map pocket 300 can be sewn onto the back panel 100, or a snap-fit ​​structure can be used for quick disassembly and installation. The magnetic component 500 can be made of a permanent magnet, electromagnet, or other magnetic material. Its position and strength can be adjusted according to the sensitivity of the magnetic switch 220 to ensure accurate activation of the magnetic switch 220 when the storage space 400 changes.

[0045] When the storage space 400 decreases, the magnetic component 500 moves closer to the magnetic switch 220, the magnetic switch 220 is turned off, and the light 210 is turned off; when the storage space 400 increases, the magnetic component 500 moves away from the magnetic switch 220, the magnetic switch 220 is turned on, and the light 210 is turned on.

[0046] In this application, the magnetic component 500 on the map pocket 300 cooperates with the magnetic switch 220 in the lamp module 200 to achieve automatic control of the map pocket 300's lighting through a magnetic induction mechanism. This effectively solves the problem of inconvenience caused by insufficient light, while avoiding the use of complex infrared sensing circuits, light-sensitive circuits, and MCU controllers, thereby simplifying the circuit structure and reducing costs. Specifically, the change in storage space 400 caused by the opening and closing of the map pocket 300 generates a lighting control signal through the relative displacement between the magnetic component 500 and the magnetic switch 220, replacing the traditional electronic control logic. This not only reduces interference from external ambient light detection but also achieves zero-power standby through mechanical linkage, significantly improving the reliability and economy of the structure.

[0047] The working principle of this application embodiment is as follows:

[0048] When the map pocket 300 is closed, the storage space 400 decreases, and the magnetic component 500 moves closer to the magnetic switch 220. The change in the relative position between the magnetic component 500 and the magnetic switch 220 triggers the switch to open, turning off the light 210 and preventing useless lighting. When the map pocket 300 is opened, the storage space 400 increases, and the magnetic component 500 moves away from the magnetic switch 220. The change in displacement of the magnetic component 500 triggers the switch to close, turning on the light 210 and providing immediate lighting.

[0049] The back panel 100 has a through hole 110 penetrating through it. The lamp module 200 is located on one side of the back panel 100, and the map pocket 300 is located on the other side. The light emitted by the lamp 210 can pass through the through hole 110 and illuminate the storage space 400. Specifically, the through hole 110 is a through hole structure opened in the back panel 100, which can be circular, square, or other suitable shapes, providing a penetration path for the light from the lamp 210 and ensuring that the light can effectively reach the storage space 400.

[0050] The map pocket 300 is an exposed component on the back panel 100, which fixes the light module 200 to one side of the back panel 100. The map pocket 300 is located on the other side of the back panel 100 and can cover the light module 200 to improve the aesthetics.

[0051] The lamp module 200 also includes a lamp holder 230, which is connected to the back plate 100. The lamp holder 230 includes a connected base body 231 and a transparent lamp cover 232, which is inserted into the through hole 110. The light lamp 210 includes a lamp body 211 and a first terminal 212 and a second terminal 213 disposed on the lamp body 211. The first terminal 212 and the second terminal 213 are both connected to the base body 231, and the lamp body 211 is housed in the transparent lamp cover 232.

[0052] In practical applications, the base 231 is the main load-bearing part of the lamp holder 230. It is made of rigid material and can withstand certain external impacts while maintaining its shape stability. The transparent lampshade 232 allows light to pass through while protecting the internal components; its material can be polycarbonate or glass. Furthermore, the first terminal 212 and the second terminal 213 are key components for achieving electrical connections. They can be fixed to the base 231 via threaded connections or snap-fit ​​connections 311 to ensure reliable conductivity.

[0053] Specifically, the design of the transparent lampshade 232 inserted into the through hole 110 allows the light to accurately illuminate the storage space 400, reducing light scattering and energy loss. The lamp body 211 of the light-emitting lamp 210 is completely housed within the transparent lampshade 232, which not only concentrates the light output but also effectively prevents external dust or liquid from entering.

[0054] Furthermore, the lamp module 200 also includes a first wire 240, a second wire 250, a third wire 260, and a connector 270 for connecting to the seat wiring harness. The magnetic switch 220 includes a first reed and a second reed. One end of the first wire 240 is connected to the first terminal 212, and the other end of the first wire 240 is connected to the first reed. One end of the second wire 250 is connected to the second reed, and the other end of the second wire 250 is connected to the connector 270. One end of the third wire 260 is connected to the second terminal 213, and the other end of the third wire 260 is connected to the connector 270. When the magnetic component 500 approaches the magnetic switch 220, the first reed separates from the second reed, and the first wire 240 disconnects from the second wire 250. When the magnetic component 500 moves away from the magnetic switch 220, the first reed contacts the second reed, and the first wire 240 and the second wire 250 become conductive.

[0055] In this circuit, the first wire 240 connects the first terminal 212 of the lamp 210 to the first spring, the second wire 250 connects the second spring to an external power source, and the third wire 260 connects the second terminal 213 of the lamp 210 to an external power source, thus forming a complete circuit path. When the magnetic component 500 approaches, the first and second springs separate, thereby cutting off the circuit and extinguishing the lamp 210; when the magnetic component 500 moves away, the first and second springs contact each other, thereby conducting the circuit and illuminating the lamp 210. Furthermore, the connector 270 allows the lamp module 200 to quickly connect to the seat wiring harness, further improving the convenience of installation and maintenance.

[0056] refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The back panel 100 includes a back panel body 120 and a light-transmitting cover 130. The light-transmitting cover is fitted onto one side of the back panel body 120 and covers one end of the through hole 110. A post 121 is provided on the other side of the back panel body 120, and a socket 231 is provided on the base 231, into which the post 121 is inserted. Specifically, by fitting the light-transmitting cover 130 onto the back panel body 120, one end of the through hole 110 can be covered, preventing the through hole 110 and the transparent lampshade 232 from being exposed, thus improving the overall aesthetics of the back panel 100. The light-transmitting cover 130 is made of a light-transmitting material, allowing light from the lamp 210 to pass through.

[0057] The insert post 121 is a protruding structure on the back plate 100, which can be cylindrical, square, or other geometric shapes with supporting and positioning functions. The socket 231a is a groove or through hole 110 formed on the base 231 that matches the insert post 121, and can be formed by machining, injection molding, or other methods. The cooperation between the insert post 121 and the socket 231a ensures that the lamp holder 230 can be firmly installed on the back plate 100. The insert post 121 and the socket 231a can be heat-welded together to further improve the stability of the lamp holder 230 installation.

[0058] The seat 231 has a mounting groove 231b, in which the magnetic switch 220 is disposed. Specifically, the mounting groove 231b is a recessed structure formed on the seat 231 to accommodate the magnetic switch 220, which can be a rectangular groove, a circular groove, or other shapes adapted to the shape of the magnetic switch 220. The mounting groove 231b provides a fixed mounting position for the magnetic switch 220, preventing displacement of the magnetic switch 220 due to external vibration or dynamic changes during seat use, thereby improving the reliability of controlling the illumination of the light 210.

[0059] The map bag 300 includes a map bag body 310 and a cover 320. The map bag body 310 is connected to the back panel 100, and the cover 320 covers the side of the map bag 300 away from the back panel 100. A magnetic component 500 is located on the cover 320 near the back panel 100. The map bag body 310 is the main load-bearing component providing the storage space 400, and it can be fixedly connected to the back panel 100 by sewing, gluing, or snapping. The magnetic component 500 is located on the cover 320 near the back panel 100 to prevent it from being exposed, and the opening and closing of the cover 320 directly moves the magnetic component 500 closer to or further away from the magnetic switch 220, thereby precisely controlling the on / off state of the light 210.

[0060] In one embodiment, the map bag body 310 is provided with a buckle 311, and the back panel 100 is provided with a slot 140, with the buckle 311 engaging in the slot 140. When the map bag 300 needs to be installed, simply align the buckle 311 with the slot 140 and apply appropriate pressure to allow the buckle 311 to smoothly insert into the slot 140, thereby achieving a quick connection between the map bag body 310 and the back panel 100. When it is necessary to open the map bag 300 or place items, the buckle 311 can move within the slot 140, increasing or decreasing the distance between the map bag body 310 and the back panel 100 to change the size of the storage space 400.

[0061] Furthermore, the back panel 100 is provided with a retractable connecting strap 150, which connects to the map bag body 310. The connecting strap 150 is a flexible component with elasticity and can be made of spring steel, elastic fabric, or silicone material, providing flexible movement space for the map bag body 310. The map bag body 310 is a bag-shaped structure for storing items, and its movement is achieved through cooperation with the connecting strap 150.

[0062] When the storage space 400 increases, the connecting strap 150 is stretched to ensure that the magnetic component 500 can stably move away from the magnetic switch 220; when the storage space 400 decreases, the connecting strap 150 retracts to ensure that the magnetic component 500 reliably approaches the magnetic switch 220 so that the light 210 remains off when the map pocket 300 is closed, reducing power consumption.

[0063] This application also discloses a seat, including a backrest and a seat back panel structure, with the back panel 100 connected to the backrest. By providing the seat back panel structure on the backrest, lighting is provided for the storage space 400 inside the map pocket 300, facilitating rear passengers to retrieve items from the map pocket 300.

[0064] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
