Description

Technical Field

[0001] This utility model belongs to the field of automotive armrest box technology, and particularly relates to a magnetic point light source structure for a sub-dashboard armrest box. Background Technology

[0002] A car armrest is a car accessory installed between two seats, belonging to the automotive interior system. Its ergonomic design aims to provide a place for the driver's arm to rest during long drives, preventing soreness, numbness, and stiffness. The armrest also includes storage space for storing items.

[0003] Existing point light source systems for automotive armrest boxes use micro switches, which are mounted on the armrest frame. The exposed switch structure of the micro switch affects the aesthetics of the design. Mechanical switches have a large pressing stroke, making them prone to malfunctions and limiting structural layout. The switches are also not refined, with buttons protruding too high, making them susceptible to vibration and rattling noises. Furthermore, different configurations require multiple molds. Therefore, this invention proposes a magnetic point light source structure for the sub-dashboard armrest box to solve these problems. Summary of the Invention

[0004] This utility model provides a magnetic point light source structure for the sub-dashboard armrest box, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a magnetic point light source structure for a sub-dashboard armrest box, including an upper armrest cover, a lower armrest cover, an armrest frame, a magnetic switch assembly, and a magnet;

[0006] The upper and lower covers of the armrests are welded using hot plates.

[0007] The magnetic switch assembly is mounted on the armrest frame, the magnet is embedded in the lower cover of the armrest, and the magnet is designed to withstand high temperatures to avoid demagnetization at high temperatures.

[0008] The magnetic switch assembly includes a switch protective housing, which is mounted on the armrest frame. A magnetic control switch is provided inside the switch protective housing. The magnetic control switch is connected to the ambient light via a wiring harness, and the wiring harness is connected to the vehicle body wiring harness via a wiring harness connector.

[0009] Preferably, the handrail frame is also provided with a handrail lock, which is used to open and close the handrail.

[0010] Preferably, the magnet has a mis-proof structure to prevent the magnetic poles of the magnet from being reversed.

[0011] Preferably, the magnet is located above the magnetic switch assembly.

[0012] Preferably, when the armrest lock is unlocked, the ambient light is turned on when the upper and lower covers of the armrest are at an angle greater than 30° to the armrest frame.

[0013] Preferably, the magnetic control switch is connected in series with the ambient light. The magnetic control switch includes a reed switch. When the internal contacts of the reed switch are under the action of a magnetic field, the contacts are open, that is, the circuit is disconnected and the ambient light is turned off. When the internal contacts of the reed switch are not affected by the magnetic field, the circuit is in a conductive state, that is, the circuit is connected and the ambient light is turned on.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When the armrest is closed, the distance between the lower cover of the armrest and the reed switch in the magnetic control switch is less than 20mm. At this time, the internal contacts of the reed switch open under the magnetic field of the magnet, thus breaking the circuit and turning off the ambient light. When the armrest is open, i.e., when the upper and lower covers of the armrest are at an angle greater than 30° to the armrest frame, the distance between the lower cover of the armrest and the reed switch in the magnetic control switch is greater than 20mm. At this time, the internal contacts of the reed switch are not affected by the magnetic field of the magnet, thus breaking the circuit and turning on the ambient light. When the armrest is opened, the ambient light illuminates accordingly.

[0016] 2. The magnet is equipped with a mistake-proof structure to prevent the switch from being uncontrollable if the magnet poles are installed in reverse. The N pole and S pole of the magnet affect the switch. The N pole can activate the magnetic attraction control switch, while the S pole cannot. Therefore, a mistake-proof structure needs to be designed to ensure that the S pole of the magnet faces the magnetic attraction control switch after installation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figures 1 to 7This utility model provides a technical solution: a magnetic point light source structure for a sub-dashboard armrest box, including an upper armrest cover 1, a lower armrest cover 2, an armrest frame 3, a magnetic switch assembly 4, and a magnet 5; the upper armrest cover 1 and the lower armrest cover 2 are welded by hot plate; the magnetic switch assembly 4 is installed on the armrest frame 3, and the magnet 5 is embedded in the lower armrest cover 2. The magnet 5 adopts a high temperature resistant design to avoid the problem of high temperature demagnetization; the magnetic switch assembly 4 includes a switch protection housing 41, which is installed on the armrest frame 3. A magnetic control switch 42 is provided inside the switch protection housing 41. The magnetic control switch 42 is connected to an ambient light 44 through a wiring harness 43, and the wiring harness 43 is connected to a vehicle body wiring harness through a wiring harness connector 45.

[0032] In this embodiment, the upper armrest cover 1 and the lower armrest cover 2 are welded using a hot plate. The magnetic switch assembly 4 is mounted on the armrest frame 3, and the magnet 5 is embedded in the lower armrest cover 2. The magnetic control switch 42 includes a reed switch and is connected in series with the ambient light 44. (See attached drawing.) Figure 6 When the handrail is closed, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is less than 20mm. At this time, the internal contacts of the reed switch are disconnected under the magnetic field of the magnet 5, thus the circuit is broken and the ambient light 44 is turned off. When the handrail is open, that is, when the upper cover 1 and the lower cover 2 of the handrail are at an angle greater than 30° to the handrail frame 3, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is greater than 20mm. At this time, the internal contacts of the reed switch are not affected by the magnetic field of the magnet 5, thus the circuit is connected and the ambient light 44 is turned on. When the handrail is opened, the ambient light 44 is lit, which not only provides lighting for the interior space of the handrail to facilitate the retrieval of items, but also has a certain atmosphere and enhances the user experience. This magnetic point light source structure is installed inside the handrail frame 3, which does not affect the aesthetics of the shape. It is also compact in structure, occupies little space, and can simultaneously light up the ambient light 44 when the handrail is opened.

[0033] See appendix Figure 5 The magnet 5 is equipped with a mistake-proof structure to prevent the switch from being uncontrollable if the magnetic poles of the magnet 5 are installed in reverse. The N pole and S pole of the magnet 5 affect the switch. The N pole can activate the magnetic attraction control switch 42, while the S pole cannot activate the magnetic attraction control switch 42. Therefore, a mistake-proof structure needs to be designed to ensure that the S pole of the magnet 5 faces the magnetic attraction control switch 42 after installation.

[0034] The magnetic control switch 42 is a passive component that consumes no power in standby mode. Because the switch contacts are sealed in a glass tube, they will not be oxidized and will not generate electrical sparks. It has the advantages of reliable and stable performance and long service life. It is widely used in various household appliances, automobiles, medical devices, industrial automation, security, access control, safety interlocks, positioning and other fields.

[0035] For further details, please refer to Figure 1 and Figure 3 The handrail frame 3 is also equipped with a handrail lock 6, which is used to open and close the handrail.

[0036] In this embodiment, the handrail is opened and closed by pressing the handrail lock 6.

[0037] For further details, please refer to Figure 5 Magnet 5 is equipped with a fault-prevention structure to prevent the magnetic poles of magnet 5 from being reversed.

[0038] In this embodiment, the magnet 5 is provided with a mistake-proof structure to prevent the switch from being uncontrollable if the magnetic poles of the magnet 5 are installed in reverse. The N pole and S pole of the magnet 5 affect the switch. The N pole can activate the magnetic attraction control switch 42, while the S pole cannot activate the magnetic attraction control switch 42. Therefore, a mistake-proof structure needs to be designed to ensure that the S pole of the magnet 5 faces the magnetic attraction control switch 42 after installation.

[0039] For further details, please refer to Figure 6 and Figure 7 Magnet 5 is located above magnetic switch assembly 4.

[0040] In this embodiment, the magnet 5 is positioned above the magnetic switch assembly 4 in order to achieve the change in distance between the magnet 5 and the magnetic attraction control switch 42 in the magnetic switch assembly 4.

[0041] For further details, please refer to Figure 7 When the armrest lock 6 is unlocked, and the upper cover 1 and lower cover 2 of the armrest are at an angle greater than 30° to the armrest frame 3, the ambient light 44 will be lit.

[0042] Furthermore, the magnetic control switch 42 is connected in series with the ambient light 44. The magnetic control switch 42 includes a reed switch. When the internal contacts of the reed switch are under the action of a magnetic field, the contacts are open, that is, the circuit is disconnected and the ambient light 44 is turned off. When the internal contacts of the reed switch are not affected by the magnetic field, the circuit is in a conducting state, that is, the circuit is connected and the ambient light 44 is turned on.

[0043] In this embodiment, refer to the appendix. Figure 6When the handrail is closed, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is less than 20mm. At this time, the internal contacts of the reed switch are disconnected under the magnetic field of the magnet 5, thus the circuit is broken and the ambient light 44 is turned off. When the handrail is open, that is, when the upper cover 1 and the lower cover 2 of the handrail are at an angle greater than 30° to the handrail frame 3, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is greater than 20mm. At this time, the internal contacts of the reed switch are not affected by the magnetic field of the magnet 5, thus the circuit is connected and the ambient light 44 is turned on. When the handrail is opened, the ambient light 44 is lit, which not only provides lighting for the interior space of the handrail to facilitate the retrieval of items, but also has a certain atmosphere and enhances the user experience. This magnetic point light source structure is installed inside the handrail frame 3, which does not affect the aesthetics of the shape. It is also compact in structure, occupies little space, and can simultaneously light up the ambient light 44 when the handrail is opened.

[0044] The working principle and usage process of this utility model: The upper armrest cover 1 and the lower armrest cover 2 are welded by hot plate. The magnetic switch assembly 4 is installed on the armrest frame 3, and the magnet 5 is embedded in the lower armrest cover 2. The magnetic attraction control switch 42 includes a reed switch and is connected in series with the ambient light 44. See the appendix. Figure 6 When the handrail is closed, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is less than 20mm. At this time, the internal contacts of the reed switch are disconnected under the magnetic field of the magnet 5, thus the circuit is broken and the ambient light 44 is turned off. When the handrail is open, that is, when the upper cover 1 and the lower cover 2 of the handrail are at an angle greater than 30° to the handrail frame 3, the distance between the lower cover 2 of the handrail and the reed switch in the magnetic control switch 42 is greater than 20mm. At this time, the internal contacts of the reed switch are not affected by the magnetic field of the magnet 5, thus the circuit is connected and the ambient light 44 is turned on. When the handrail is opened, the ambient light 44 is lit, which not only provides lighting for the interior space of the handrail to facilitate the retrieval of items, but also has a certain atmosphere and enhances the user experience. This magnetic point light source structure is installed inside the handrail frame 3, which does not affect the aesthetics of the shape. It is also compact in structure, occupies little space, and can simultaneously light up the ambient light 44 when the handrail is opened.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
