Description

Technical Field

[0001] This application generally relates to the field of vehicle-mounted temperature chamber technology, and specifically to a vehicle-mounted temperature chamber. Background Technology

[0002] Vehicle temperature boxes, as an important device to improve driving comfort and convenience, have been widely used in various vehicles; among them, pull-out vehicle temperature boxes are favored for their convenient access to items and high space utilization.

[0003] Currently, common pull-out vehicle temperature boxes generally consist of a box body and a drawer connected to it via a sliding rail mechanism. The drawer is usually driven by a spring-assisted semi-automatic pop-out structure. To enhance the stability of the drawer after it is opened and to prevent accidental sliding during vehicle travel, existing technologies typically use friction dampers to provide relatively uniform resistance to the overall movement of the drawer. However, while a single friction damper can provide some buffering and deceleration, the damping force it provides is basically constant or has a limited range of variation. When the vehicle is traveling, constant friction damping is difficult to completely counteract the inertial force, which may cause the drawer to still shift, affecting not only ease of use but also posing safety hazards and inconvenience.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example 1 Please refer to Figures 1-18This application provides a vehicle-mounted temperature box, which can be a refrigeration box providing refrigeration and freezing functions, or a heating box providing heating and insulation functions, or a temperature box that has both refrigeration and heating functions and can switch between the two functions, including: The box 1 has a first chamber 2 inside, and a first opening is provided on one side of the first chamber 2 along a first direction. A drawer 3 is movably inserted into the first chamber 2 along the first opening. The drawer 3 is movably connected to the first chamber 2 by a driving structure. The first direction is parallel to the length direction of the drawer 3. In this embodiment, the first direction is the horizontal direction. The driving structure includes: Mounting base 4 is located on the bottom wall of the first chamber 2; a driving assembly is provided between the mounting base 4 and the drawer 3, the driving assembly being used to provide the driving force to make the drawer 3 pop out. At least one corrugated rack 5 is provided. The corrugated rack 5 is provided at the bottom of the drawer 3 and extends along the first direction. The corrugated rack 5 is provided with periodically alternating corrugated teeth, and the corrugated teeth have a concave-convex profile. The hovering component 19 is disposed on the mounting base 4 and is located near the first opening. The hovering component 19 contacts the corrugated rack 5. The hovering component 19 is used to alternately engage with the corrugated rack during the drawer 3's pull-out stroke, thereby enabling the drawer 3 to hover in multiple different positions.

[0020] Specifically, such as Figure 1 As shown, the drive component is located between the mounting base 4 and the drawer 3. Its core function is to provide the necessary driving force for the drawer 3 to pop out, so as to realize the automatic or semi-automatic opening of the drawer 3. In this embodiment, the drive component is used to drive the drawer 3 to open semi-automatically. Specifically, such as Figure 2 As shown, in this embodiment, in order to ensure the stability of the drawer 3 during the pulling process, two corrugated racks 5 are provided, and the two corrugated racks 5 are arranged along the second direction; similarly, the hovering components 19 are provided with two sets of corrugated racks 5. Working principle: During use, the drawer 3 is automatically popped out by the drive component. Then, the user can manually continue to pull the drawer 3 to fully open the refrigerator. During the entire pulling process, the suspension component 19, in cooperation with the wave rack 5, not only effectively buffers the movement of the drawer 3, but also allows it to reliably hover at any desired position within its travel range. It can be seen that this structure effectively overcomes the defect of traditional friction dampers that are prone to displacement when the damping force is constant due to vehicle bumps, and significantly improves the stability and safety of the drawer 3 under different road conditions.

[0021] In some implementations, the hovering component 19 includes: Support member 6, with a nylon ball 7 on the top, and corrugated teeth located at the bottom of corrugated rack 5, the nylon ball 7 being used to contact and engage with the corrugated teeth; The first elastic element 8 has one end fixedly connected to the support element 6 and the other end fixedly connected to the mounting base 4.

[0022] Specifically, such as Figures 4-5 As shown, the hovering assembly 19 includes a support member 6 and a first elastic member 8. In this embodiment, the first elastic member 8 is a spring. A nylon ball 7 is provided on the top of the support member 6. In this embodiment, the corrugated teeth are located at the bottom of the corrugated tooth rack 5. The nylon ball 7 is configured to maintain contact with the corrugated teeth and cooperate with them, so as to roll or slide along the surface of the corrugated tooth rack 5 during the process of pulling out the drawer 3. In this embodiment, the first elastic element 8 is sleeved on the outside of the support 6, with one end connected to the support 6 and the other end fixedly connected to the mounting base 4. Through the preload provided by the first elastic element 8, the support 6 and its top nylon ball 7 can always conform to the contour changes of the corrugated teeth, achieving continuous and stable damping and positioning. This structure can automatically adapt to and generate varying damping forces according to the undulations of the corrugated teeth's peaks and troughs (i.e., as shown in the image). Figure 4 As shown, when drawer 3 moves, the nylon ball 7 rises when it passes the trough of the corrugated teeth; as Figure 5 As shown, the nylon ball 7 descends when passing the crest of the corrugated teeth, thus achieving reliable hovering at multiple different positions during the pull-out stroke. At the same time, it effectively suppresses the unexpected displacement of the drawer 3 caused by vibration during vehicle operation, enhancing the adaptability and safety of the overall structure.

[0023] In some implementations, the hovering component 19 includes: The housing 9 is mounted on the mounting base 4. The interior of the housing 9 is hollow. A push rod 10 is movably mounted on one end of the housing 9 along the second direction. One end of the push rod 10 extends into the interior of the housing 9. A corrugated rack 5 is provided with corrugated teeth on the side facing the push rod 10. The push rod 10 is used to contact and engage with the corrugated teeth. The second direction is perpendicular to the first direction. In this embodiment, the second direction is a horizontal direction. The second elastic element 11 is disposed inside the housing 9. One end of the second elastic element 11 is fixedly connected to the top rod 10, and the other end is fixedly connected to the inner wall of the housing 9.

[0024] Specifically, such as Figure 18 As shown, the hovering assembly 19 mainly includes a housing 9, a push rod 10, and a second elastic element 11; in this embodiment, the second elastic element 11 is a spring; the housing 9 is fixedly installed on the mounting base 4, and its interior is hollow. The push rod 10 is movably provided at one end of the housing 9 along the second direction, and one end of the push rod 10 extends into the interior of the housing 9; the other end of the push rod 10 is used to contact and cooperate with the wave teeth. Specifically, in this embodiment, such as Figure 16 and Figure 17 As shown, the hovering assembly 19 and the wave rack 5 are each provided with two sets, and the ends of the two push rods 10 that are far apart from each other are respectively in contact with the corresponding wave rack 5; in some embodiments, the two push rods 10 share a second elastic element 11, and the two ends of the second elastic element 11 are respectively connected to the two push rods 10. In this embodiment, the second elastic element 11 is housed in the internal cavity of the housing 9. One end of the elastic element is connected to the end of the push rod 10 extending into the housing 9, while the other end is fixedly connected to the inner wall of the housing 9. With this configuration, the second elastic element 11 continuously applies a force pointing outward to the push rod 10, causing the push rod 10 to always tend to extend outward. When the drawer 3 is pulled out, the corrugated teeth at the bottom of the drawer 3 contact and interact with the exposed end of the push rod 10. Under the compression of the corrugated tooth profile, the push rod 10 can overcome the force of the second elastic element 11 and generate a reciprocating extension and retraction motion. This motion automatically adapts to the undulations of the corrugated teeth and generates a changing damping force (i.e., when the drawer 3 moves, the push rod 10 rises when passing through the trough of the corrugated teeth and falls when passing through the crest of the corrugated teeth), thereby achieving smooth suspension and effective positioning of the drawer 3 at any position during the pull-out stroke, significantly enhancing the adaptability and reliability of the product under different operating conditions.

[0025] In some implementations, the driving structure includes: There are two slide rails 12, which are respectively set on both sides of the mounting base 4 along the second direction and extend along the first direction, providing a track base for the directional movement of the drive plate 13. The drive plate 13 has two ends that are slidably connected to the slide rail 12, enabling it to reciprocate stably in the first direction. A damper is provided on the side of the drive plate 13 near the first opening. The damper is used to provide necessary buffering and resistance during the movement. The limiting member 15 extends along the first direction and is disposed on the mounting base 4 and is located on the side of the damper near the first opening. The limiting member 15 is disposed corresponding to the damper and is used to abut against the damper to limit the final stroke of the drive plate 13 in the opening direction. Push plate 16 is provided at the bottom of drawer 3 and is used to contact the side of drive plate 13 near the first opening. The driving component 17 is mounted on the mounting plate. The driving end of the driving component 17 is connected to the driving plate 13. The driving component 17 is used to drive the driving plate 13 to move the push plate 16 toward the first opening direction, and then drive the drawer 3 to perform the pop-out action through the push plate 16.

[0026] Specifically, in use, the drive plate 13 is first driven by the drive component 17, which causes the push plate 16 to move toward the first opening, thereby driving the drawer 3 to pop out. When the damper moves to abut against the limit component 15, the drive plate 13 stops moving, while the push plate 16 continues to move a distance toward the first opening under inertia. Subsequently, the user can manually continue to pull out the drawer 3 to fully open the refrigerator. During the entire pulling process, the suspension component 19, in cooperation with the wave rack 5, not only effectively buffers the movement of the drawer 3, but also allows it to reliably hover at any desired position within its travel range. Specifically, in this embodiment, in order to ensure the stability of the drawer 3 during the pulling process, two push plates 16 are provided, and the two push plates 16 are arranged along the second direction.

[0027] In some embodiments, the damper is a linear hydraulic damper 14, and the end of the linear hydraulic damper 14 near the limiting member 15 is provided with an elastic telescopic rod 18, which is used to abut against the limiting member 15.

[0028] Specifically, such as Figures 2-3 as well as Figures 8-11 As shown, the damper is a linear hydraulic damper 14. Based on its mature hydraulic technology, the linear hydraulic damper 14 avoids errors during installation, reduces wear and damage rates, has high ejection efficiency, and is an independent component, resulting in lower repair and replacement costs after damage. Specifically, the linear hydraulic damper 14 has an elastic telescopic rod 18 at one end near the limiting member 15, which is used to achieve flexible contact with the limiting member 15. When the drive plate 13 drives the linear hydraulic damper 14 to move towards the limiting member 15, the elastic telescopic member first contacts the limiting member 15, and its elastic deformation can effectively absorb the initial impact energy and avoid generating rigid collision noise; subsequently, the main body of the linear hydraulic damper 14 begins to play the main buffering role, and its internal hydraulic damping effect converts kinetic energy into heat energy and dissipates it, thereby ensuring that the drive plate 13 and even the entire drawer 3 system achieve smooth, gentle and shock-free deceleration and stopping.

[0029] In some implementations, the damper includes: The rack 20 is disposed on the mounting base 4 along the first direction and passes through the drive plate 13; The damping gear 21 is disposed on the side of the drive plate 13 near the first opening. The damping gear 21 meshes with the rack 20, and the end of the damping gear 21 is used to abut against the limiting member 15.

[0030] Specifically, such as Figures 12-15As shown, the damper is implemented using a gear-rack 20 damping structure, which mainly consists of a rack 20 and a damping gear 21. The rack 20 is fixedly installed on the mounting base 4 along the first direction, and its installation position passes through the channel or space reserved in the drive plate 13, providing a fixed reference base for the entire damping system; the damping gear 21 is located on the side of the drive plate 13 near the first opening, and the damping gear 21 meshes with the rack 20; when the drive member 17 drives the drive plate 13 to move towards the first opening, the damping gear 21 is forced to rotate under the constraint of the fixed rack 20, and its internal damping mechanism converts the linear motion kinetic energy of the drive plate 13 into heat energy and dissipates it, thereby providing a smooth and controllable first stage of deceleration buffer for the pop-out process of the drawer 3; at the same time, when the end of the damping gear 21 abuts against the limiting member 15, the drive plate 13 stops moving.

[0031] In some embodiments, the drive element 17 is a coil spring, which is mounted on the mounting base 4 and located on the side of the hovering assembly 19 near the first opening, and the drive end of the coil spring is fixedly connected to the drive plate 13.

[0032] Specifically, such as Figure 17 As shown, the driving component 17 is a coil spring, which is mounted on the mounting base 4 and located on the side of the hovering assembly 19 near the first opening, thereby optimizing the space utilization and power transmission efficiency of the overall layout. The driving end of the coil spring is fixedly connected to the driving plate 13, thereby directly converting its own elastic potential energy into traction or thrust on the driving plate 13; In this embodiment, two coil springs are provided, and the driving ends of the two coil springs are respectively connected to both sides of the drive plate 13 along the second direction to improve the stability of the movement of the drive plate 13.

[0033] In some embodiments, a switching component is also included, the switching component comprising: A toggle switch 22 is located at the end of the mounting base 4 away from the first opening and is rotatably connected to the mounting base 4; Locking element 24 is provided at the bottom of drawer 3 and is correspondingly provided with toggle switch 22; toggle switch 22 has a first state and a second state. When it is in the first state, toggle switch 22 abuts against locking element 24; when it is in the second state, toggle switch 22 is separated from locking element 24. The drive motor 23 is mounted on the mounting base 4, and the drive end of the drive motor 23 is fixedly connected to one end of the toggle switch 22; the drive motor 23 is used to drive the toggle switch 22 to switch between the first state and the second state.

[0034] Specifically, the vehicle temperature box also includes an electronically controlled switch assembly for locking and releasing the drawer 3; this switch assembly mainly includes a toggle switch 22, a locking element 24, and a drive motor 23. The toggle switch 22 is rotatably connected to the mounting base 4, and its installation position is located at the end of the mounting base 4 away from the first opening (i.e., near the rear end of the first chamber 2); correspondingly, a locking element 24 is fixedly provided at the bottom of the drawer 3, and the position of the locking element 24 corresponds to the swing range of the toggle switch 22, so that the toggle switch 22 can be engaged or disengaged from it; Toggle switch 22 has two distinct operating states: such as Figure 6 As shown, in the first state (usually the locked state), the toggle switch 22, under the action of the drive motor 23 or without external force, abuts against the locking member 24, thereby preventing the drawer 3 from moving; as Figure 7 As shown, in the second state (unlocked state), the toggle switch 22 disengages from the locking member 24, releasing the restriction on the movement of the drawer 3; the drive motor 23 is fixedly mounted on the mounting base 4, and its drive end is fixedly connected to one end of the toggle switch 22; by receiving control signals, the drive motor 23 can precisely drive the toggle switch 22 to rotate, thereby reliably switching between the first state and the second state; this design realizes the electric control of the drawer 3's locked state, improving the product's intelligence level and ease of operation.

[0035] Specifically, the complete opening process of drawer 3 begins with a user command trigger. First, the drive motor 23 starts, driving the toggle switch 22 from the first state to the second state, separating it from the locking member 24 at the bottom of drawer 3 and releasing the mechanical lock on drawer 3. Subsequently, the coil spring, which is in a pre-tensioned and stored state, is released, and its drive end rebounds, pulling the drive plate 13 to move along the slide rail 12 towards the first opening. During the movement, the drive plate 13 achieves smooth buffering and deceleration on one side through the action of a damper, while simultaneously pushing the bottom push plate 16 of drawer 3 in contact with it, causing drawer 3 to smoothly spring back. The first segment of the stroke begins; when the damper at the front end of the drive plate 13 abuts against the limit member 15 on the mounting base 4, the drive plate 13 stops moving, and the drawer 3 slides briefly under inertia; thereafter, the user can manually continue to pull out the drawer 3. At this time, the corrugated rack 5 at the bottom of the drawer 3 and the suspension component 19 at the front end of the mounting base 4 enter a working state. The undulating contour of the corrugated rack forces the suspension component 19 to move accordingly and generate a changing damping force. This damping force not only consumes the kinetic energy of the drawer 3 to slow it down, but also enables the drawer 3 to reliably stop at any position throughout the entire pulling process, thereby completing the entire opening operation.

[0036] In some embodiments, a rotating shaft 25 is rotatably connected to the middle of the toggle switch 22, and the rotating shaft 25 is fixedly connected to the mounting base 4; one end of the toggle switch 22 is fixedly connected to the driving end of the drive motor 23, and the other end of the toggle switch 22 is used to abut against the locking member 24.

[0037] Specifically, such as Figures 6-7 As shown, in this embodiment, the toggle switch 22 has an overall L-shaped structure, which facilitates the transmission of force and the conversion of the direction of movement. The middle part of the toggle switch 22 is rotatably connected to the mounting base 4 through a rotating shaft 25; the rotating shaft 25 is fixedly installed on the mounting base 4, providing a reliable rotation fulcrum for the swing of the toggle switch 22, ensuring that its rotation process is stable and the axis does not deviate. Specifically, one end of the toggle switch 22 is fixedly connected to the drive end of the drive motor 23, thereby directly converting the rotational output of the motor into the swing motion of the toggle switch 22 around the rotating shaft 25. The other end is configured to abut or disengage from the locking member 24. By controlling the L-shaped toggle switch 22 to rotate around the rotating shaft 25 by a certain angle through the drive motor 23, its working end can be raised or lowered, thereby achieving reliable separation or tight engagement with the locking member 24, completing the locking and releasing of the drawer 3. This L-shaped lever design amplifies the displacement of the motor drive end, allowing its working end to obtain sufficient stroke to reliably disengage from the locking member 24. At the same time, the structure is simple and compact, easy to assemble and control, and effectively improves the reliability and consistency of the switch assembly's operation.
