Description

Technical Field

[0001] This utility model relates to the field of automotive armrest box technology, specifically an automotive center armrest box and an automotive. Background Technology

[0002] With the development of the automotive industry and the upgrading of consumption, users have put forward higher requirements for the intelligence, comfort and user experience of vehicle interiors. As an important storage and functional component in the vehicle, the design quality of the center armrest box in the sub-dashboard area directly affects the overall quality of the vehicle and the user's daily experience. Related technical fields have been working to improve the convenience, technological feel and integration of the components in this area.

[0003] In the prior art, some innovative solutions have emerged aimed at optimizing the user experience of armrest boxes. For example, Chinese utility model patent with authorization announcement number CN222682276U discloses an armrest box cover and a center console armrest box. This solution sets up an automatic opening component driven by a telescopic spring, so that the cover can automatically flip to the maximum opening degree after unlocking. At the same time, it links an internal lifting plate through a gear-pull rope transmission mechanism to automatically lift the items in the storage box when the cover is opened, making it convenient for users to access them and effectively improving the ease of use.

[0004] However, the above-mentioned and similar existing technical solutions still have obvious shortcomings in the opening experience of the cover; their opening process directly relies on the instantaneous elastic force of the spring and lacks an effective buffering mechanism, resulting in the cover opening action being fast and abrupt, which not only generates impact noise but also affects the lifespan of the components. Utility Model Content

[0005] In view of the technical problems in the prior art, the present invention provides a car center armrest box and a car, which aims to solve the problem that the armrest box cover lacks buffering due to the lack of instantaneous elasticity when it is automatically opened, resulting in large movement impact, easy abnormal noise, and affecting the service life of the components.

[0006] The technical solution of this utility model is implemented as follows: A car center console armrest box includes a box body, a cover, and a buffer structure, wherein, The opening side of the box is hinged to the cover plate via a pivot, and a torsion spring is provided on the pivot to provide a force in the opening direction of the cover plate; The buffer structure includes a moving part and a buffer part; The movable component is slidably disposed inside the box near the hinge of the cover plate, and the movable component is movably connected to the cover plate; The buffer is located inside the box and abuts against the top of the movable part; When the cover plate opens under the action of the torsion spring, the cover plate drives the moving part to slide upward and abut against the buffer, thereby providing opening damping force; when the cover plate closes, the cover plate drives the moving part to slide downward to disengage from the buffer, so that the closing process is undamped.

[0007] Optionally, the movable component includes a buffer plate and a connecting rod, wherein, The buffer plate is located inside the box body near the hinge of the cover plate, and a sliding cavity is longitudinally opened on the side wall of the box body corresponding to the buffer plate. One end of the connecting rod is hinged to the buffer plate, and the other end extends obliquely upward to the cover plate and is hinged thereto.

[0008] Optionally, the housing is provided with at least one longitudinal guide rod, and the buffer plate is slidably engaged with the guide rod.

[0009] Optionally, the buffer includes a damper, wherein, The damper is fixedly mounted longitudinally at the top of the sliding cavity, and the bottom piston rod end of the damper abuts against the buffer plate.

[0010] Optionally, a car center console also includes a locking structure, said locking structure comprising an electromagnetic adsorption assembly and an armature, wherein, The electromagnetic adsorption component is located on the side of the box opening away from the hinge of the cover plate; The armature is located at the corresponding electromagnetic adsorption component on the cover plate; The electromagnetic adsorption component is configured to generate a magnetic force to attract the armature when energized, thereby keeping the cover plate locked.

[0011] Optionally, the electromagnetic adsorption assembly includes an electromagnet and a trigger switch, wherein, The electromagnet is detachably located on the side of the box opening away from the hinged cover plate and is electrically connected to the vehicle's power supply system. The trigger switch is fixedly installed at the edge of the opening of the housing and connected in series in the power supply circuit of the electromagnet; The pressing part of the trigger switch is located on the closing path of the cover plate. When the cover plate is closed, the cover plate presses the pressing part, causing the trigger switch to connect the power supply circuit of the electromagnet.

[0012] Optionally, the electromagnetic adsorption assembly may further include a control terminal; The control terminal is located at the end of the housing and is connected in series in the power supply circuit of the electromagnet. It is used to receive the vehicle power-on signal and control the power supply of the electromagnet.

[0013] Optionally, a car center armrest box also includes an electromagnetic locking pin, which is located at the edge of the box opening and electrically connected to the vehicle's power supply system. The electromagnetic locking pin is configured to: be energized when the vehicle is powered on to release the mechanical lock on the cover plate; and be de-energized when the vehicle is powered off to mechanically lock the cover plate in the closed state.

[0014] Optionally, a car center console may also include a cushioning pad; The buffer pad is fixedly attached to the edge of the opening of the box to buffer the impact of the cover plate on the box when the cover plate is closed.

[0015] This utility model also provides a car, including the above-mentioned car center armrest box.

[0027] Please see Figure 1-6 The present application proposes a car center armrest box, which includes a box body 1, a cover plate 2 and a buffer structure 3.

[0028] like Figure 1-3 As shown, the opening side of the housing 1 is hinged to the cover plate 2 via a pivot, and a torsion spring 101 is provided on the pivot to provide the force for opening the cover plate 2; the buffer structure 3 includes a movable part 31 and a buffer part 32; the movable part 31 is slidably disposed inside the housing 1 near the hinge of the cover plate 2, and the movable part 31 is movably connected to the cover plate 2; the buffer part 32 is disposed inside the housing 1 and abuts against the top of the movable part 31; when the cover plate 2 is opened under the action of the torsion spring 101, the cover plate 2 drives the movable part 31 to slide upward and abut against the buffer part 32, thereby providing opening damping force; when the cover plate 2 is closed, the cover plate 2 drives the movable part 31 to slide downward to disengage from the buffer part 32, so that the closing process is undamped.

[0029] Specifically, the opening and closing process is fully optimized through the synergistic effect of the torsion spring 101 and the buffer structure 3. When the user unlocks the device, the torsion spring 101 provides stable opening power, while the movable part 31 moves upward under the action of the cover plate 2 and compresses the buffer 32, transforming the traditional instantaneous opening into a smooth, slow opening, effectively eliminating impact noise. During the closing process, the movable part 31 moves downward with the cover plate 2 and completely disengages from the buffer 32, ensuring a smooth and unobstructed closing action. This one-way buffer mechanism solves the technical contradiction between the stiff opening in traditional solutions and the poor closing caused by ordinary dampers, significantly improving the operational feel and user experience.

[0030] In some embodiments, such as Figure 2 , Figure 4-5As shown, the movable component 31 includes a buffer plate 311 and a connecting rod 312. The buffer plate 311 is located inside the housing 1 near the hinge of the cover plate 2. A sliding cavity 102 is longitudinally formed on the side wall of the housing 1 corresponding to the buffer plate 311. One end of the connecting rod 312 is hinged to the buffer plate 311, and the other end extends obliquely upward to the cover plate 2 and is hinged thereto. When the cover plate 2 is open, the connecting rod 312 pulls the buffer plate 311 to move closer to the buffer component 32. When the cover plate 2 is closed, the connecting rod 312 pushes the buffer plate 311 to move away from the buffer component 32.

[0031] Specifically, this embodiment achieves precise control of power transmission through a linkage mechanism consisting of a buffer plate 311 and a connecting rod 312. The inclined arrangement of the connecting rod 312 converts the rotational motion of the cover plate 2 into the linear motion of the buffer plate 311. This conversion method is simple in structure and has high transmission efficiency. During the opening process, the connecting rod 312 pulls the buffer plate 311 to smoothly approach the buffer member 32. During the closing process, it pushes the buffer plate 311 to quickly disengage, ensuring different mechanical characteristics in the two directions of motion. This four-bar linkage operates reliably and effectively ensures the realization of the technical effects of smooth opening and smooth closing.

[0032] In some embodiments, such as Figure 2 , Figure 4-5 As shown, the housing 1 is provided with at least one longitudinal guide rod 313, and the buffer plate 311 is slidably engaged with the guide rod 313.

[0033] Specifically, in this embodiment, the stability of the moving parts is significantly improved by the setting of the guide rod 313. The guide rod 313 is preferably made of 45 steel and the surface is chrome-plated to reduce the coefficient of friction. The buffer plate 311 is provided with a copper-based self-lubricating bushing that matches the guide rod 313. This matching method can not only ensure that the buffer plate 311 runs smoothly in the sliding cavity 102, but also effectively reduce wear and improve the durability and operational reliability of the product.

[0034] In some embodiments, such as Figure 4 As shown, the buffer 32 includes a damper, which is longitudinally fixed at the top of the sliding cavity 102, and the bottom piston rod end of the damper abuts against the buffer plate 311.

[0035] Specifically, in this embodiment, a rotary hydraulic damper is selected as the buffer element. When the buffer plate 311 moves upward to compress the damper, the piston rod retracts at a controllable speed, converting the elastic potential energy of the torsion spring 101 into heat energy dissipation, thereby achieving smooth deceleration. This design controls the opening time of the cover plate 2 within the range of 1.5-2 seconds, ensuring opening efficiency while avoiding rapid impact.

[0036] In some embodiments, such as Figure 1-3 , Figure 5-6 As shown, a car center armrest box also includes a locking structure 4, which includes an electromagnetic adsorption component 41 and an armature 42. The electromagnetic adsorption component 41 is located on the side of the box body 1 away from the hinge of the cover plate 2. The armature 42 is located on the cover plate 2 corresponding to the electromagnetic adsorption component 41. The electromagnetic adsorption component 41 is configured to generate magnetic force to attract the armature 42 when energized, so that the cover plate 2 remains locked.

[0037] Specifically, this embodiment achieves intelligent locking through electromagnetic adsorption; the electromagnetic adsorption component 41 adopts an E-type magnetic core structure powered by DC12V, which can generate a holding force of not less than 50N when energized; the armature 42 is made of DT4C electrical pure iron material, which has high permeability and low remanence; when the cover plate 2 is closed, the gap between the electromagnetic adsorption component 41 and the armature 42 is controlled at 1-2mm, ensuring adsorption reliability while reducing energy consumption; this locking method does not require mechanical buckles, eliminating the wear and noise problems of traditional locking mechanisms, and achieving a reliable locking effect.

[0038] In some embodiments, such as Figure 2 , Figure 6 As shown, the electromagnetic adsorption assembly 41 includes an electromagnet 411 and a trigger switch 412. The electromagnet 411 is detachably located on the side of the opening of the housing 1 away from the hinged cover plate 2 and is electrically connected to the vehicle's power supply system. The trigger switch 412 is fixedly located on the edge of the opening of the housing 1 and connected in series in the power supply circuit of the electromagnet 411. The pressing part of the trigger switch 412 is located on the closing path of the cover plate 2. When the cover plate 2 is closed, the cover plate 2 presses the pressing part, so that the trigger switch 412 connects the power supply circuit of the electromagnet 411.

[0039] Specifically, this embodiment achieves automated locking control through a trigger switch 412. The trigger switch 412 is a waterproof micro switch with a trigger stroke of 1.5mm and a mechanical life of over 100,000 cycles. When the cover plate 2 is closed to the last 5 degrees, it begins to contact the pressing part of the trigger switch 412, achieving stable pressing when fully closed. This design ensures that the electromagnet 411 is energized only when locking is required, saving energy and improving safety. Actual tests show that the response time of this trigger system is less than 0.1 seconds, providing users with a convenient experience of locking with a single close.

[0040] In some embodiments, such as Figure 3 As shown, the electromagnetic adsorption assembly 41 also includes a control terminal 413; the control terminal 413 is located at the end of the housing 1 and is connected in series in the power supply circuit of the electromagnet 411, and is used to receive the vehicle power-on signal and control the power on and off of the electromagnet 411.

[0041] Specifically, this embodiment achieves intelligent management of the locking system through the control terminal 413. The control terminal 413 uses an automotive-grade MCU as the main control chip and integrates a CAN bus communication module, enabling it to receive vehicle power status signals. When the vehicle is detected to be powered on, the control terminal 413 automatically activates the locking system; when the vehicle is turned off, the system enters power-saving mode. The control terminal 413 also has a fault diagnosis function, which can monitor the working status of the electromagnet 411 in real time and alert the user through the instrument panel when an abnormality occurs. This intelligent control strategy ensures both ease of use and improved system reliability.

[0042] In some embodiments, such as Figure 2 , Figure 6 As shown, a car center armrest box also includes an electromagnetic lock pin 5, which is located at the edge of the opening of the box 1 and is electrically connected to the vehicle power supply system. The electromagnetic lock pin 5 is configured to: be energized when the vehicle is powered on to release the mechanical lock on the cover 2; and be de-energized when the vehicle is powered off to mechanically lock the cover 2 in the closed state.

[0043] Specifically, this embodiment provides dual security through the electromagnetic lock pin 5. The electromagnetic lock pin 5 adopts a push-pull electromagnet structure, which maintains the locked position through a permanent magnet in the power-off state, with zero power consumption. When the vehicle is powered on, the electromagnetic lock pin 5 generates a reverse magnetic field, releasing the mechanical constraint on the cover plate 2. When the vehicle is powered off, the mechanical lock is automatically restored. This fail-safe design ensures the security of the storage space when the vehicle is off, effectively preventing the theft of important items, while avoiding the inconvenience of needing an additional key for traditional mechanical locks.

[0044] In some embodiments, such as Figure 2 , Figure 6 As shown, a car center armrest box also includes a buffer pad 6; the buffer pad 6 is fixedly attached to the opening edge of the box body 1 and is used to buffer the impact of the cover plate 2 on the box body 1 when the cover plate 2 is closed.

[0045] Specifically, this embodiment further optimizes the closing experience through the buffer pad 6. The buffer pad 6 is made of EPDM rubber with a Shore hardness of 60±5, exhibiting excellent resistance to compression set and aging resistance. The buffer pad 6 is firmly attached to the edge of the opening of the housing 1 with 3M VHB double-sided tape, and its thickness is designed to be 3mm, providing effective cushioning when the cover 2 is closed. Tests have shown that this design can reduce the closing impact noise from 75dB to below 55dB, while effectively avoiding direct metal contact between the cover 2 and the housing 1, preventing paint wear, and extending the product's service life.

[0046] This utility model also provides an automobile, including the aforementioned center armrest box, which integrates the center armrest box into the entire vehicle, significantly improving the vehicle's practicality and user experience. In actual vehicle testing, the armrest box exhibits excellent comprehensive performance: the opening and closing process is smooth and stable, the locking function is intelligent and reliable, and the durability meets the vehicle's service life requirements. In particular, in terms of NVH performance, it effectively eliminates the common abnormal noise problems of traditional armrest boxes. This high-quality interior component not only improves users' daily satisfaction but also enhances the overall vehicle's market competitiveness, providing automakers with a differentiated product advantage.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
