[0021] The container body (1) includes a support structure (3) and a container cover (4). The support structure (3) includes a fixed bracket (31), a slider (32), and a slide rail (33). The fixed bracket (31) belongs to the container body (1) and is fixed to the slider (32). The slider is fixed on the slide rail (33) and slides. The fixed bracket (31) slides as the container body (1) slides on the guide rail. The container cover (4) includes a cover support rod (41), a hinge (42), and a locking post (43). The end of the cover support rod (41) is the locking post (43). The locking post (43) is connected to the cover support rod (41) through the hinge (42). The end of the locking post (43) is located in the limiting guide groove (7) of the limiting plate (5) and slides in the limiting guide groove (7) as the container body slides on the guide rail (81). The installation structure includes a limiting plate (5) and a press-rebound structure (6). The limiting plate (5) has a limiting guide groove (7), which is divided into a horizontal section (71) and an arc section (72). The press-rebound structure includes a transmission structure (8) and a motor, which drives the container body to slide. The transmission structure (8) is divided into a guide rail (81), a transmission belt (82), a gear (83), and a rack (84). The gear (83) and the rack (84) are anchored together. The transmission belt (82), the gear (83), and the rack (84) drive the container body (1) to slide on the guide rail (81) under the drive of the motor.

[0022] In a specific embodiment, this utility model is applied below the passenger side dashboard of an automobile as a hidden cup holder / storage compartment. It must meet automotive-grade vibration (GB / T 28046-2011) and high-temperature resistance (-40℃~85℃) requirements, and be linked with the central control system to achieve voice control activation. The components can be implemented using the following specific structures and materials: In a specific embodiment, the slide rail (33) of the container body (1) adopts a self-lubricating slide rail for automobiles with an anti-detachment locking mechanism. The slide rail (33) and the cabinet are filled with polyurethane damping rubber with a Shore hardness of 70A, which can withstand 50g acceleration impact when the vehicle collides.

[0023] In a specific embodiment, the cover support rod (41) of the container cover (4) is replaced with a magnesium alloy die casting (size 80×15×3mm), which reduces the weight by 40% while maintaining a bending stiffness of ≥200N / mm².

[0024] In a specific embodiment, the limiting plate (5) of the installation structure (2) is injection molded with PA66 and 30%GF. The arc segment (52) of the limiting guide groove is designed as a three-segment variable curvature curve (initial curvature radius 30mm → middle stage 60mm → final stage 15mm) to match the natural movement trajectory of the human elbow.

[0025] In a specific embodiment, the rack (84) of the transmission structure (8) in the pressing and rebounding structure (6) of the mounting structure (2) is molded on the bottom of the container body and forms a backlash-free meshing with the gear (83) with a backlash of ≤0.1mm. The gear (83) is equipped with a wave spring washer to eliminate the backlash and ensure that no abnormal noise is generated under vibration environment.

[0026] In a specific embodiment, the motor in the press-rebound structure (6) of the mounting structure (2) is a 12V DC brushless motor with IP67 protection level, and integrates a CAN bus interface, which responds within 0.3s after receiving the central control "open cover" command.

[0027] In a specific embodiment, the motor is driven by a motor driver after receiving a signal.

[0028] In a specific embodiment, the working principle of the gravity pressing container is as follows: 1. Signal triggering stage: The language command triggers the CAN bus to send a message to power the motor; 2. Power transmission stage: The rotation of the motor rotor drives the 0.8 gear (83) to push the rack (84), the rack (84) drives the transmission belt (82), and the transmission belt (82) drags the fixed bracket (31) to move along the slide rail (33); 3. Flipping stage: When the locking post (43) moves to the arc section (72) of the limit guide groove (7), the support rod (41) is subjected to normal force, and the hinge (42) torsion spring provides additional torque, so that the container cover (4) flips up at an angular velocity of 60° / s.

[0029] In a specific embodiment, the gravity-pressed container is linked with the central control system to achieve voice-controlled activation. The beneficial effects of this specific embodiment are as follows: Vibration and shake resistance: Backlash-free gears with a side clearance of ≤0.1mm and self-lubricating slide rails maintain container displacement fluctuation of <0.3mm under 20Hz random vibration. The anti-vibration function helps to improve the service life of the tailgate and reduce maintenance costs.

[0030] durable: After simulating 50,000 opening and closing cycles, the wear of the limit guide groove is low and the belt loss is small.

[0031] Intelligent Interaction: The CAN bus control supports multimodal operation via voice or touch screen, with a short response time and 50% higher efficiency than traditional mechanical buttons.

[0032] Space optimization: The segmented variable curvature limiting guide groove allows the cover to occupy only 80mm of vertical space after it is flipped up, which is 40mm less than the 120mm required by the traditional design, thus improving leg comfort.

[0033] Easy to install and maintain: The overall structural design takes into account the ease of installation, and the connection between the various components is simple and clear, making it easy for the press container to be assembled on the automobile production line.

[0053] In a specific embodiment, the fixed bracket (31) in the support structure (3) of the container body (1) is made of aluminum alloy extrusion molding, with an inverted U-shaped cross section. A PTFE wear-resistant sheet with a thickness of 2mm is attached to the inner side, which slides in contact with the inner wall of the cabinet, reducing the coefficient of friction to below 0.1.

[0054] In a specific embodiment, the slider (32) and slide rail (33) in the support structure (3) of the container body (1) are of the same type. The slider adopts a double-row ball bearing type, and the slide rail adopts a cold-rolled steel C-shaped groove with a cross-sectional size of 20×15mm. The clearance between the two is 0.5mm and the stroke is 150mm.

[0055] In a specific embodiment, the cover plate support rod (41) of the container cover plate (4) of the container body (1) is made of 304 stainless steel rod with a diameter of 6mm and M4 threads are processed at both ends. One end of the cover plate support rod (41) is connected to a hinge (42) and the other end is welded with a locking post (43).

[0056] In a specific embodiment, the hinge (42) of the container cover (4) of the container body (1) adopts a two-stage force hinge (such as Blum 71.936). The first stage force maintains the cover plate horizontally, and the second stage force provides 8 N·m torque to assist in turning when the locking post enters the arc section.

[0057] In a specific embodiment, the container cover plate (4) of the container body (1) has a cylindrical pin with a hard chrome plating tolerance of h6 on the surface of the pin (43), and a 3mm wide annular groove is machined at the end to form a line contact with the limiting guide groove (7).

[0058] In a specific embodiment, the limiting guide groove (7) on the limiting plate (5) of the mounting structure (2) is made of 304 stainless steel plate with a thickness of 3mm and machined by CNC. The horizontal section is 120mm long and the arc section is an involute profile with a central angle of 60° (the equation of the involute profile is r=50+0.2θ, θ∈[0,60°]).

When the locking pin (43) moves to the starting point of the arc section (72) of the limiting guide groove, the torque of the hinge (42) overcomes the gravitational torque of the cover plate, causing the container cover plate (4) to flip up at a constant speed until the locking pin (43) contacts the magnetic attraction point (not shown) to complete the positioning. The beneficial effect of this embodiment is: High efficiency and effortless: Driven by a 24V DC worm gear motor and using synchronous belt transmission, the container is smoothly pushed out with low thrust, making it easy for the elderly and children to operate.

[0063] Precise positioning: A Hall encoder with an accuracy of 0.5° is used in conjunction with a magnetic positioning point made of neodymium iron boron magnets to ensure that the opening and closing position error of the cover plate is ≤±1mm, avoiding repeated adjustments.

[0064] Quiet and durable: The combination of polyurethane synchronous belts and ball bearing slides reduces operating noise and minimizes wear after repeated use.

[0065] The advantages of this utility model are as follows: By adopting the above technical solution and using a hidden design, the space inside the smart cockpit and RV is saved, the overall aesthetics are maintained, and protruding parts are avoided from interfering with other functional areas; it can be opened and closed with one button, making it easy to operate; it prevents accidental touches and improves safety; the absence of exposed handles reduces the risk of bumps and damage and reduces mechanical wear; the modular design facilitates maintenance or upgrades; and the absence of handles reduces costs.
