Description

Technical Field

[0001] This utility model relates to the field of armrest boxes, and more particularly to an armrest box that opens and closes via electromagnetic induction. Background Technology

[0002] A car armrest is an accessory installed between two seats and belongs to the car's 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.

[0003] Most existing armrest boxes use a small partition to divide the internal space, while below the partition is a larger space. Therefore, placing items in this space can easily lead to clutter and accumulation, making it difficult to find the items you need.

[0004] Therefore, it is necessary to provide an armrest box that opens and closes via electromagnetic induction to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an armrest box that opens and closes via electromagnetic induction, which solves the issues of existing armrest boxes where items tend to pile up and become disorganized, making it difficult to find the items needed.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an electromagnetic induction opening and closing armrest box, comprising: a box body and a slide groove, the slide groove being opened on both sides of the front and back sides inside the box body, a slider being slidably connected inside the slide groove, a through hole being opened inside the slider, a fixing rod being disposed inside the through hole, the bottom of the fixing rod being fixedly connected to the bottom of the inner wall of the slide groove, a spring being disposed on the surface of the fixing rod and located at the bottom of the slider, a reinforcing rod being fixedly connected to the inner side of the slider, a first support plate being fixedly installed on the top of the reinforcing rod, a powerful magnet being fixedly installed on the bottom of the reinforcing rod, and a fixing magnet being fixedly installed on the bottom of the inner side of the box body and directly below the powerful magnet;

[0007] A connecting rod is fixedly connected to the top of the slider. A second support plate is fixedly installed on the top of the connecting rod. A support rod is fixedly installed on the top of the second support plate. A third support plate is fixedly installed on the top of the support rod.

[0008] Preferably, the top front and back of the enclosure are provided with electromagnetic induction opening and closing covers.

[0009] Preferably, a placement box is provided on the top of the third tray and inside the electromagnetic induction opening and closing cover.

[0010] Preferably, both connecting rods and support rods have a central hole inside.

[0011] Preferably, the opening and closing method of the electromagnetic induction opening and closing cover is a symmetrical rotation centered on the position where it is connected to the box body.

[0012] Preferably, the magnetic attraction between the powerful magnet and the fixed magnet is greater than the elastic force of the spring.

[0013] Preferably, the usable space of the three first trays, second trays and third trays gradually increases to fit the internal usable space of the box.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This invention provides an armrest box that opens and closes via electromagnetic induction. Its core innovation lies in achieving dynamic layering of the internal space of the armrest box through a combination of mechanical structure and electromagnetic induction technology. The armrest box has a multi-layered support structure inside, specifically including a first support, a second support, and a third support. Each support is linked by a slider and a spring assembly. When the electromagnetic induction device receives an opening / closing signal, the spring force pushes the slider upwards, causing the support to smoothly extend from the box, forming three independent usable spaces.

[0016] This layered design not only makes full use of the vertical height of the armrest box but also avoids the mixing and stacking of items through physical separation, solving the problems of low internal space utilization and easy disorganization of items in traditional armrest boxes. Users can classify and store items according to type (such as mobile phones, documents, snacks, etc.), significantly improving the rationality of space planning and retrieval efficiency. In addition, the tray uses a silent guide rail and buffer design when extended to ensure the smoothness and quietness of the operation process, which is suitable for the quality requirements of high-end models.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-5 As shown in the figure, this application discloses an electromagnetic induction opening and closing armrest box, including: a box body 1 and a slide 4. The slide 4 is opened on both sides of the front and back sides inside the box body 1. A slider 5 is slidably connected inside the slide 4. A through hole 6 is opened inside the slider 5. A fixing rod 7 is arranged inside the through hole 6. The bottom of the fixing rod 7 is fixedly connected to the bottom of the inner wall of the slide 4. A spring 8 is arranged on the surface of the fixing rod 7 and at the bottom of the slider 5. A reinforcing rod 9 is fixedly connected to the inner side of the slider 5. A first support plate 10 is fixedly installed on the top of the reinforcing rod 9. A strong magnet 11 is fixedly installed on the bottom of the reinforcing rod 9. A fixing magnet 12 is fixedly installed on the bottom of the inner side of the box body 1 and directly below the strong magnet 11.

[0025] A connecting rod 13 is fixedly connected to the top of the slider 5. A second support plate 14 is fixedly installed on the top of the connecting rod 13. A support rod 15 is fixedly installed on the top of the second support plate 14. A third support plate 16 is fixedly installed on the top of the support rod 15.

[0026] Electromagnetic induction opening and closing covers 2 are provided on the top front and back of the box 1.

[0027] A placement box 3 is provided on the top of the third tray 16 and inside the electromagnetic induction opening and closing cover 2.

[0028] Both connecting rods and support rods 15 have a central hole 17 inside.

[0029] The opening and closing method of the electromagnetic induction opening and closing cover 2 is a symmetrical rotation centered on the position where it is connected to the box body 1.

[0030] The magnetic attraction between the strong magnet and the fixed magnet 12 is greater than the elastic force of the spring 8.

[0031] The usable space of the three first trays 10, the second tray 14 and the third tray 16 is gradually increased to fit the internal usable space of the box 1.

[0032] Cover opening: The cover is opened by rotating through electromagnetic induction, revealing the top opening of the box 1.

[0033] When the powerful magnet 11 moves down with the slider and aligns with the fixed magnet 12, the magnetic attraction automatically attracts and fixes the tray assembly to the bottom of the box to prevent shaking.

[0034] Force balance relationship: In the closed state, the magnetic attraction force and the combined force of the strong magnet and the fixed magnet are greater than the spring force, and the tray remains fixed; when opened, the manual pulling force and the spring force are greater than the magnetic attraction force, and the tray pops out.

[0035] Layered and categorized storage: Three shelves vertically divide the space, preventing items from piling up and improving retrieval efficiency.

[0036] Automated pop-out mechanism: Through the mechanical cooperation of spring and magnet, the complexity of manual operation is reduced, and the "pull and pop out" opening is made convenient.

[0037] Space adaptability: The pallet size is designed to fit the internal space of the box, avoiding wasted space.

[0038] Electromagnetic induction control: The automatic opening and closing of the cover enhances the intelligent experience and is suitable for scenarios such as vehicles that require convenient operation.

[0039] tray unlocking and ejection:

[0040] Manually pull the third support plate 16 upwards. The force is transmitted to the second support plate 14 through the support rod 15, and then through the connecting rod 13, it drives the slider 5 to slide upwards along the fixed rod 7 in the slide groove 4.

[0041] When the pulling force exceeds the magnetic attraction force of the strong magnet 11 and the fixed magnet 12, the two are separated from the magnetic attraction state.

[0042] As the magnetic attraction is released, the spring 8 undergoes elastic deformation, generating an upward thrust that pushes the slider 5 and the linked three-layer support plate to continue moving upward until the top of the first support plate 10 is flush with the opening of the box, and the three-layer support plate extends completely out of the box.

[0043] Item retrieval: The three-tiered trays are exposed in layers, allowing users to quickly retrieve items by category, such as placing larger items on the bottom layer and frequently used small items on the top layer.

[0044] Linkage transmission chain: slider 5 to reinforcing rod 9 → to first support plate 10 and connecting rod 13 to second support plate 14 to support rod 15 to third support plate 16, forming a vertical force transmission chain.

[0045] Reinforcing rod 9: Connects the slider and the first support plate, enhances structural stability, and transmits the force for vertical movement.

[0046] By using the fixing rod 7, the position of the spring 8 can be limited, preventing changes in its position during operation or non-operation, which would prevent the slider 5 from being pushed upward normally. The use of the slider 5 and the slide groove 4 can improve the stability of movement. The length of the fixing rod 7 is the same as the depth of the box 1. The support rod 15 and the connecting rod 13 both have a center hole 17. When the three trays are stored in the box 1, the fixing rod will be in the center hole 17.

[0047] The working principle of the electromagnetic induction opening and closing armrest box provided by this utility model is as follows:

[0048] When it is necessary to take an item from the armrest box 1, the armrest box can be opened by electromagnetic induction opening and closing cover 2. Then, the placement box 3 placed on the box body 1 and under the electromagnetic induction opening and closing cover 2 when it is closed can be taken out by lifting upwards. Then, the third tray 16 can be pulled upwards manually. Then, the support rod 15 will be subjected to force by the force of the third tray 16, which will cause the second tray 14 and the connecting rod 13 to be subjected to force, which will cause the slider 5 to move upwards inside the slide groove 4 and on the surface of the fixed rod 7. Therefore, when the slider 5 is subjected to upward force, its reinforcing rod 9 will be subjected to upward force until its force is greater than the magnetic attraction between the strong magnet 11 and the fixed magnet 12, so that the two will be separated from the magnetic attraction state.

[0049] Subsequently, the elastic deformation of the spring 8 can push the slider 5 upward, and the related structure connected to the slider 5 moves upward until the top of its first tray 10 and the top opening of the box 1 are level and stop. Therefore, the three trays placed inside the box 1 extend upward, and the work of picking up items can be carried out at this time.

[0050] After the retrieval is completed, the third tray 16 can be pushed downwards to move the slider 5 downwards in the slide groove 4 and squeeze the spring 8, so that the three trays are retracted into the box 1. Then, the three trays can be fixed in the box 1 by the magnetic attraction between the strong magnet 11 and the fixed magnet 12.

[0051] Compared with related technologies, the electromagnetic induction opening and closing armrest box provided by this utility model has the following beneficial effects:

[0052] The spring 8 pushes the slider 5 upward, causing the first tray 10, the second tray 14, and the third tray 16 to extend upward from the box 1, thus dividing the space into three layers. Items can be categorized when placed in these three layers, allowing for quick retrieval when needed. Furthermore, the layered placement avoids the situation where items are piled up and become messy when placed in one layer.

[0053] This armrest box's layered design not only optimizes item organization but also enables intelligent control through electromagnetic induction technology. This layered layout significantly reduces clutter caused by item accumulation, making it particularly suitable for long-distance driving or family trips. Furthermore, the electromagnetic induction system can be linked to the vehicle's central control system to automatically retract the tray when the vehicle is turned off, preventing accidental collisions or items slipping out. This design, through the combination of structural innovation and intelligent technology, addresses the practicality issues of traditional armrest boxes while enhancing the aesthetics and technological feel of the vehicle interior, providing a completely new solution for the automotive interior design field.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
