[0002] The drawers of the car refrigerator are driven by a motor, with a rope connection between the motor and the drawer to automatically open or close for user convenience. To prevent noise caused by resonance between the motor and the refrigerator body during drawer movement, related technologies use shock-absorbing pads between the bottom of the motor and the base of the refrigerator body to reduce vibration and noise. However, during drawer movement, the shock-absorbing pads must withstand the tension of the rope. This tension is parallel to the drawer's sliding direction and can cause abnormal deformation and failure of the pads, reducing reliability, affecting the motor's installation stability, and resulting in noise generation.

[0024] In car refrigerators, drawers for placing items are driven by motors for user convenience. Typically, the motor and drawer are connected by a rope to automatically open or close the drawer.

[0025] To prevent noise caused by resonance between the motor and the refrigerator body during drawer movement, a shock-absorbing pad is installed between the bottom of the motor and the base of the refrigerator body in related technologies. This pad buffers the motor's vibration, effectively reducing noise. However, during drawer movement, the rope exerts a reaction force on the motor, while the shock-absorbing pad bears the tension from the rope along the drawer's sliding direction. This tension is perpendicular to the deformation direction of the shock-absorbing pad when buffering the motor's vibration, causing abnormal deformation and failure of the pad. This reduces reliability, affects the motor's installation stability, and leads to noise generation.

[0026] Therefore, referring to Figures 1 to 9 As shown, the first aspect of this utility model provides a vehicle refrigerator, which is applied to a vehicle. Generally speaking, the vehicle refrigerator is installed in the center armrest box of the vehicle. Reference Figure 1 and Figure 2 As shown, the vehicle refrigerator includes a base 100, a drawer body 400, a drive assembly 300, and a first shock absorber 600. Additionally, the vehicle refrigerator includes a mounting base 200 and an inner liner 500. Specifically, the inner liner 500 has a storage cavity 510 with an opening facing the front of the vehicle refrigerator. The base 100, mounting base 200, drive assembly 300, first shock absorber 600, and drawer body 400 are all installed within the storage cavity 510. The upper end of the drawer body 400 is open, and the drawer body 400 can extend from the opening on the front side of the storage cavity 510 to facilitate users storing or retrieving items from the drawer body 400.

[0027] It is easy to understand that, for user convenience, the storage compartment 510 typically also has an opening facing upwards towards the car refrigerator, so that users can access items from the top of the car refrigerator.

[0028] Reference Figures 1 to 3As shown, it can be understood that the base 100 is located at the bottom of the storage cavity 510 and is fixedly connected to the inner liner 500. For example, the base 100 and the inner liner 500 are fixedly connected by a snap-fit ​​structure, or by fasteners such as screws and bolts. The mounting base 200 is located on the upper side of the base 100 and is slidably mounted on the base 100 in the front-back direction. Specifically, a linear guide rail 110 is connected between the mounting base 200 and the base 100. The linear guide rail 110 consists of two sections of rails that slide in the front-back direction. The two sections of rails are arranged in the front-back direction and fixedly connected to the bottom of the mounting base 200 and the top of the base 100, respectively. To improve the sliding stability of the mounting base 200, two linear guide rails 110 are connected between the mounting base 200 and the base 100. The two linear guide rails 110 are located at the left and right ends of the base 100 and are parallel to each other.

[0029] Reference Figure 1 and Figure 2 As shown, the drawer body 400 is mounted on the upper side of the mounting base 200. Typically, the drawer body 400 and the mounting base 200 are detachably connected; for example, the drawer body 400 is fixed to the mounting base 200 with screws. This allows the drawer body 400 to move in the front-back direction, that is, the drawer body 400 can slide relative to the base 100, and the sliding direction of the drawer body 400 is the front-back direction. Thus, the drawer body 400 can extend through the opening on the front side of the storage cavity 510, allowing the user to store or retrieve items from the drawer body 400.

[0030] Reference Figures 1 to 3 As shown, it can be understood that the drive assembly 300 is installed between the base 100 and the mounting base 200 and is used to drive the mounting base 200 to move in the front-back direction, that is, to drive the drawer body 400 to move in the front-back direction. Specifically, the drive assembly 300 includes a drive unit 310 and a bracket 360. In addition, in this embodiment, the drive assembly 300 also includes a winding wheel 320, a driven wheel 330 and a rope 340. The drive unit 310 and the driven wheel 330 are respectively installed on the base 100 and arranged at intervals in the front-back direction. Specifically, the drive unit 310 and the driven wheel 330 are respectively installed at both ends of the base 100 in the front-back direction, wherein the drive unit 310 is installed at the rear end of the base 100 and the driven wheel 330 is installed at the front end of the base 100.

[0031] Reference Figure 2 and Figure 3As shown, it can be understood that the bracket 360 is mounted on the base 100, and in the sliding direction of the drawer body 400, the bracket 360 can move relative to the base 100 within a certain range of travel, and the travel of the bracket 360 is less than the travel of the drawer body 400. The drive unit 310 is mounted on the bracket 360. Specifically, the drive unit 310 consists of a drive motor 311 and a reducer 312. The reducer 312 is fixedly mounted on the bracket 360, the output end of the drive motor 311 is connected to the input end of the reducer 312, and the drive motor 311 is fixedly connected to the reducer 312. The winding wheel 320 is fixedly mounted on the output shaft of the reducer 312. The output shaft of the reducer 312 is arranged in the left-right direction, that is, the rotation axis of the winding wheel 320 is arranged in the left-right direction.

[0032] Reference Figure 2 and Figure 3 As shown, it can be understood that the driven wheel 330 is rotatably mounted on the base 100, and the rotation axis of the driven wheel 330 is arranged in the left-right direction, that is, the rotation axis of the driven wheel 330 is parallel to the rotation axis of the winding wheel 320. The driven wheel 330 is located directly in front of the winding wheel 320. In this embodiment, the base 100 is equipped with a floating seat 331, which slides with the base 100 in the front-back direction, and a spring connects the floating seat 331 and the base 100, so that the floating seat 331 can move relative to the base 100 in the front-back direction within the elastic range of the spring.

[0033] Reference Figure 2 and Figure 3 As shown, it can be understood that the two ends of the rope 340 are defined as the first end 341 and the second end 342, respectively. The rope 340 is wound between the winding reel 320 and the driven reel 330. Specifically, the rope 340 is wound around the winding reel 320 multiple times to increase the friction between the rope 340 and the winding reel 320 and prevent slippage. The section of the rope 340 near the first end 341 extends towards the driven reel 330 and passes over the driven reel 330 from bottom to top, and the first end 341 is fixed to the mounting base 200. For example, the mounting base 200 is provided with a snap-fit ​​groove, the section of the rope 340 near the first end 341 is accommodated in the snap-fit ​​groove, and the first end 341 is knotted, so that the knot at the first end 341 is snapped into place with the mounting base 200. Of course, the first end 341 can also be directly fixed to the mounting base 200 by fasteners such as screws, or the first end 341 can be directly bound to the mounting base 200.

[0034] Reference Figure 2 and Figure 3As shown, it can be understood that a section of the rope 340 near the second end 342 extends towards the driven wheel 330 and is connected to the mounting base 200. Similarly, the connection method between the second end 342 and the mounting base 200 can refer to the connection method between the first end 341 and the mounting base 200, which will not be repeated here. In this embodiment, the mounting base 200 is provided with an adjusting wheel 350. The second end 342 of the rope 340 is knotted and secured to the adjusting wheel 350, or the second end 342 of the rope 340 is directly bound to the adjusting wheel 350. Therefore, by rotating the adjusting wheel 350, the rope 340 can be wound around the adjusting wheel 350 or released from the adjusting wheel 350, thereby adjusting the tension of the rope 340, so that the rope 340 maintains a suitable tension, thereby extending the service life of the rope 340 and improving the transmission reliability of the rope 340.

[0035] Reference Figures 1 to 3 As shown, it can be understood that after adjusting the tension of the rope 340, the adjusting wheel 350 is fixed relative to the mounting base 200, thus fixing both the first end 341 and the second end 342 of the rope 340. The drive motor 311 drives the rope 340 to rotate between the winding wheel 320 and the driven wheel 330 through the reducer 312. The rope 340 then drives the mounting base 200 and the drawer body 400 to move, thus realizing the transmission connection between the drive unit 310 and the drawer body 400, thereby realizing the automatic opening or closing of the drawer body 400 for user convenience.

[0036] Reference Figures 1 to 3 As shown, it can be understood that the drawer body 400 extends forward from the opening on the front side of the storage cavity 510, and the first end 341 of the rope 340 is fixed to the rear end of the mounting base 200. Therefore, it is beneficial to increase the travel of the mounting base 200 and the drawer body 400. Under the premise of ensuring the stability of the drawer body 400, the drawer body 400 can extend as far as possible from the opening on the front side of the storage cavity 510, which is convenient for storing and retrieving items.

[0037] Reference Figures 1 to 3 As shown, it can be understood that by setting the speed reducer 312, the rotational speed of the winding wheel 320 can be reduced, thereby reducing the moving speed of the drawer body 400, which is easier to control and helps to improve the moving stability of the drawer body 400.

[0038] Reference Figures 1 to 3As shown, it is understandable that when the drive motor 311 is first started, the winding wheel 320 exerts a relatively large force on the rope 340, which can easily lead to the rope 340 breaking. Therefore, by setting a floating seat 331, when the drive motor 311 is first started, the floating seat 331 moves towards the winding wheel 320 under the tension of the rope 340, thereby reducing the force applied to the rope 340 and avoiding the drawback of the rope 340 breaking due to excessive force, effectively improving the reliability of the rope 340.

[0039] Reference Figure 3 and Figure 4 As shown, it can be understood that the first damping element 600 is connected between the base 100 and the bracket 360. Specifically, in this embodiment, the first damping element 600 is configured as an elastic element such as a rubber or silicone element, which can undergo elastic deformation along the direction of force under the action of external force, and can automatically return to its original shape when the external force is removed.

[0040] Reference Figure 3 , Figure 4 and Figure 6 As shown, the bracket 360 includes a first fixing plate 361, which is perpendicular to the sliding direction of the drawer body 400. Correspondingly, the base 100 is provided with a first mounting surface 120, which is perpendicular to the sliding direction of the drawer body 400 and located on the front side of the first fixing plate 361. The first shock absorber 600 includes a main body 610 and a mounting part 620. The mounting part 620 is connected to the rear end of the main body 610 and fixedly mounted on the first fixing plate 361. The main body 610 is disposed between the first fixing plate 361 and the first mounting surface 120. Therefore, along the sliding direction of the drawer body 400, a portion of the structure of the first shock absorber 600 is located between the base 100 and the bracket 360. The first fixing plate 361, the first shock absorber 600, and the base 100 are connected together by fasteners such as screws or bolts.

[0041] It is understood that in some other embodiments, the first damping member 600 may be located entirely between the first fixing plate 361 and the first mounting surface 120. Similarly, the first fixing plate 361, the first damping member 600 and the base 100 are connected together by fasteners such as screws or bolts.

[0042] Reference Figure 3 , Figure 4 and Figure 6As shown, it can be understood that by positioning the main body 610 of the first damping member 600 between the first fixing plate 361 and the first mounting surface 120, the first damping member 600 can absorb the vibration energy of the drive unit 310 by utilizing its own elastic deformation characteristics. Furthermore, the main body 610 avoids direct contact between the base 100 and the bracket 360, reducing the vibration transmitted to the base 100, thereby effectively reducing the probability of resonance and thus effectively reducing noise. It is easy to understand that the first damping member 600 deforms primarily along the front-to-back direction when absorbing vibration energy.

[0043] Reference Figure 3 , Figure 4 and Figure 6 As shown, it can be understood that during the process of the drive motor 311 driving the drawer body 400 to move in the front-back direction, the rope 340 applies a pulling force to the winding wheel 320 from the winding wheel 320 towards the driven wheel 330, that is, the direction of the pulling force is from back to front. The pulling force is transmitted to the main body 610 of the first damping member 600 through the first fixing plate 361 of the bracket 360, and the main body 610 can be compressed and deformed under force. The direction of the force on the main body 610 is the same as the direction of deformation when the main body 610 absorbs vibration energy, so that the main body 610 can stably bear the pulling force, that is, the first damping member 600 can stably bear the pulling force, which helps to reduce the risk of failure of the first damping member 600, has high reliability, and thus ensures the installation stability of the drive unit 310. At the same time, the first damping member 600 can effectively absorb the vibration energy of the drive unit 310 and reduce the vibration transmitted to the base 100, further reducing the probability of resonance, thereby effectively reducing noise.

[0044] Reference Figure 3 and Figure 8 As shown, the bracket 360 also includes a second fixing plate 362, which is perpendicular to the left-right direction. That is, the second fixing plate 362 is arranged along the sliding direction of the drawer body 400. The second fixing plate 362 is connected to the front side of the first fixing plate 361 and is perpendicular to the first fixing part. The reducer 312 is fixedly connected to the second fixing plate 362 and abuts against the front side of the first fixing plate 361. The drive motor 311 is fixedly connected to the reducer 312, thereby improving the installation stability of the drive unit 310.

[0045] Reference Figure 3 and Figure 4As shown, it can be understood that there are two first damping components 600, which are respectively disposed on both sides of the drive unit 310 along the direction perpendicular to the sliding direction. In this embodiment, the two first damping components 600 are located on the left and right sides of the drive unit 310, respectively. The first fixing plate 361 extends to both sides of the drive unit 310 in the left and right directions, and the two first damping components 600 are respectively connected to the left and right ends of the first fixing plate 361. In this way, the number of connection points between the bracket 360 and the base 100 can be increased, and the base 100 provides support for the bracket 360 from the left and right sides of the drive unit 310, which is beneficial to improving the overall installation stability of the drive assembly 300. At the same time, the two first damping components 600 can absorb the vibration energy of the drive motor 311, which is beneficial to further reduce noise. In addition, the two first damping components 600 bear the tension of the rope 340 respectively, which can reduce the stress on each first damping component 600, thereby further reducing the risk of failure of the first damping component 600, improving reliability, and ensuring the installation stability of the drive unit 310.

[0046] It is understandable that the number of the first shock absorber 600 can be three, four or more, which will not be elaborated here.

[0047] Reference Figure 4 , Figure 6 and Figure 8 As shown, the mounting part 620 is provided with a first fixing groove 621, which is annular. Correspondingly, the first fixing plate 361 is provided with a first fixing hole 3611, the center line of which is arranged along the front-back direction. The mounting part 620 passes through the first fixing hole 3611, and the first fixing plate 361 is engaged in the first fixing groove 621, so that the two opposite side walls of the first fixing plate 361 in the front-back direction abut against the two groove walls of the first fixing groove 621 arranged opposite to each other in the front-back direction. This restricts the movement of the first shock absorber 600 relative to the first fixing plate 361 in the front-back direction, thus fixing the first shock absorber 600 to the first fixing plate 361. The first shock absorber 600 is installed firmly and reliably, effectively exerting its shock-absorbing function. It is easy to understand that, since the first shock absorber 600 has elastic deformation characteristics, when the first shock absorber 600 is installed on the first fixing plate 361, the mounting part 620 can be pressed into the first fixing hole 3611 by utilizing the compression characteristics of the first shock absorber 600 under force. This is convenient to operate and easy to install.

[0048] Reference Figure 4 , Figure 6 and Figure 8As shown, to prevent the first damper 600 from rotating around the centerline of the first fixing hole 3611, the first damper 600 also includes a limiting part 630. The limiting part 630 is a protrusion structure, connected to the outer peripheral wall of the mounting part 620, and protruding outward along the radial direction of the annular first fixing groove 621. Correspondingly, the first fixing plate 361 is provided with a limiting groove 3612, which is located on the radial side of the first fixing hole 3611 and communicates with the first fixing hole 3611. When the first fixing plate 361 is engaged with the first fixing groove 621 of the mounting part 620, the limiting part 630 is accommodated in the limiting groove 3612, thereby restricting the rotation of the first damper 600 and further improving the installation stability of the first damper 600.

[0049] Reference Figure 4 , Figure 6 and Figure 8 As shown, the main body 610 is also provided with a buffer groove 611. The buffer groove 611 is arranged around an axis parallel to the sliding direction of the drawer body 400, that is, the buffer groove 611 is arranged circumferentially along the annular first fixing groove 621. Alternatively, it can be understood that the buffer groove 611 is arranged along the direction surrounding the center line of the first fixing hole 3611. The buffer groove 611 can be annular, semi-annular, or arc-shaped, etc. Therefore, by providing the buffer groove 611, the ability of the main body 610 to deform in the front-to-back direction can be enhanced, thereby enhancing the ability of the main body 610 to absorb vibration energy and further reducing noise.

[0050] It is understandable that during the process of the drive motor 311 driving the drawer body 400 to move in the front and back direction, the winding wheel 320 rotates. Under the tension of the rope 340, the drive unit 310 and the bracket 360 tend to swing in the up and down direction, which will cause vibration and noise.

[0051] Therefore, referring to Figure 3 and Figure 5 As shown, the vehicle refrigerator also includes a second shock absorber 700, with at least a portion of its structure located between the base 100 and the bracket 360 along the vertical direction. Specifically, in this embodiment, the second fixing plate 362 is provided with a connecting plate 3621, which is located at the end of the second fixing plate 362 away from the first fixing plate 361 and is perpendicular to the vertical direction. Correspondingly, the base 100 is provided with a second mounting surface 130, which is perpendicular to the vertical direction and located below the connecting plate 3621. The upper part of the second shock absorber 700 is fixedly connected to the connecting plate 3621, and the lower part of the second shock absorber 700 is located between the connecting plate 3621 and the second mounting surface 130. The connecting plate 3621, the second shock absorber 700, and the base 100 are connected together by fasteners such as screws or bolts.

[0052] It is understood that in some other embodiments, the second damper 700 may be located entirely between the connecting plate 3621 and the second mounting surface 130. Similarly, the connecting plate 3621, the second damper 700 and the base 100 are connected together by fasteners such as screws or bolts.

[0053] Reference Figure 3 and Figure 5 As shown, it can be understood that the second damping element 700 is similarly configured as an elastic element such as rubber or silicone, capable of elastic deformation along the direction of force under external force and automatically returning to its original shape when the external force is removed. Therefore, by positioning the second damping element 700 between the connecting plate 3621 and the second mounting surface 130, and utilizing the elastic deformation characteristics of the second damping element 700 itself, the second damping element 700 can absorb the vibration energy of the drive unit 310 and the bracket 360 vibrating in the vertical direction. Furthermore, the second damping element 700 avoids direct contact between the base 100 and the bracket 360, thereby reducing the vibration transmitted to the base 100 and effectively reducing noise.

[0054] Reference Figure 3 and Figure 4 As shown, the base 100 is provided with a receiving groove 140, and the first fixing plate 361 and the first damping member 600 are disposed within the receiving groove 140. When the first fixing plate 361, the first damping member 600, and the base 100 are connected together by fasteners such as screws or bolts, the fasteners pass through the connecting holes of the first damping member 600, and the two ends of the fasteners are supported by two walls of the receiving groove 140 arranged opposite each other in the front-back direction. Generally speaking, the outer diameter of the fastener is smaller than the inner diameter of the connecting hole, so that the first fixing plate 361 and the first damping member 600 can move relative to the base 100 within a certain stroke range in the vertical direction, that is, the bracket 360 can move relative to the base 100 within a certain stroke range in the vertical direction, thereby effectively ensuring that the second damping member 700 can deform in the vertical direction and play the role of absorbing vibration energy.

[0055] Reference Figure 5 , Figure 7 and Figure 8As shown, the second damping component 700 is provided with a second fixing groove 710, which is annular. Correspondingly, the connecting plate 3621 is provided with a second fixing hole 3622, the center line of which is arranged vertically. The second damping component 700 passes through the second fixing hole 3622, and the connecting plate 3621 is engaged in the second fixing groove 710. This allows the two opposite side walls of the connecting plate 3621 to abut against the two groove walls of the second fixing groove 710, which are arranged vertically opposite to each other. This restricts the movement of the second damping component 700 relative to the connecting plate 3621 in the vertical direction, thus fixing the second damping component 700 to the connecting plate 3621. The second damping component 700 is securely and reliably installed, effectively exerting its damping effect. It is easy to understand that, since the second shock absorber 700 has elastic deformation characteristics, when the second shock absorber 700 is installed on the connecting plate 3621, the second shock absorber 700 can be pressed into the second fixing hole 3622 by utilizing the compression characteristics of the second shock absorber 700. The operation is convenient and easy to install.

[0056] Reference Figure 5 , Figure 7 and Figure 8 As shown, it can be understood that when the connecting plate 3621, the second shock absorber 700, and the base 100 are connected together by fasteners such as screws or bolts, the second shock absorber 700 is relatively fixed to the base 100. Along the sliding direction of the drawer body 400, i.e., along the front-to-back direction, the inner diameter of the second fixing hole 3622 is larger than the outer diameter of the second shock absorber 700 at the second fixing groove 710. For example, the second fixing hole 3622 is set as an elongated hole, and the length direction of the elongated hole is parallel to the front-to-back direction. The structure of the second shock absorber 700 at the second fixing groove 710 is a cylindrical structure, and the cylindrical structure passes through the elongated hole. Therefore, the connecting plate 3621 can move relative to the second shock absorber 700 within a certain range of travel in the front-to-back direction, that is, the bracket 360 can move relative to the base 100 within a certain range of travel in the front-to-back direction, thereby effectively ensuring that the first shock absorber 600 can deform along the front-to-back direction to absorb vibration energy.

[0057] Reference Figure 8 and Figure 9As shown, both the first fixing plate 361 and the second fixing plate 362 are sheet metal parts, and the first fixing plate 361 and the second fixing plate 362 are welded together. Specifically, a welding plate 3624 is provided at the end of the second fixing plate 362 near the first fixing plate 361. The welding plate 3624 is parallel to and abuts against the first fixing plate 361, and is welded to the first fixing plate 361, ensuring a stable and reliable connection. To facilitate precise positioning between the first fixing plate 361 and the second fixing plate 362, the first fixing plate 361 is provided with a positioning groove 3613, and the end of the second fixing plate 362 facing the first fixing plate 361 is provided with a positioning part 3623. The positioning part 3623 is a protruding structure and passes through the positioning groove 3613. Therefore, when assembling the bracket 360, the positioning part 3623 of the second fixing plate 362 is first inserted into the positioning groove 3613 of the first fixing plate 361 to make the first fixing plate 361 and the second fixing plate 362 accurately positioned. Then, the welding plate 3624 is welded together with the first fixing plate 361, which is convenient to operate and the connection is stable and reliable.

[0058] It is understood that in some other embodiments, the bracket 360 may be a casting, that is, the first fixing plate 361 and the second fixing plate 362 are integral castings.
