Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a sliding structure and a vehicle-mounted refrigerator. Background Art

[0002] In the early days of the industry, refrigerators configured in cars were all made in the top-opening manner. This was mainly because the usage environment of cars is relatively special, and more attention was paid to the safety during the driving process of the car. For example, during accelerating and sudden braking, the door of the vehicle-mounted refrigerator should not suddenly pop out and impact to cause harm to people. With the improvement of people's living quality requirements, more consideration has been given to automatic opening, and the drawer-type automatic opening method has emerged as the times require. On furniture drawers, we can naturally add drawer handles, but on vehicle-mounted refrigerators, adding door handles will easily hurt passengers.

[0003] Chinese Patent Document No. CN218442923U disclosed a screw-driven pull-out vehicle-mounted refrigerator in 2023. Specifically, it includes a vehicle-mounted refrigerator main body, a refrigeration chamber is provided on the vehicle-mounted refrigerator main body, and an installation chamber is located on the outer periphery of the refrigeration chamber. A guide through hole penetrating into the installation chamber is provided on the rear side wall of the refrigeration chamber. An opening communicating with the refrigeration chamber is provided on the front end face of the vehicle-mounted refrigerator main body. An end cover movably covering the opening is provided on the vehicle-mounted refrigerator main body. An evaporator for refrigerating the refrigeration chamber, a compressor and a condenser communicating with the evaporator are provided on the vehicle-mounted refrigerator main body; a pull-out drawer is provided in the refrigeration chamber and can move back and forth relative to the refrigeration chamber; a driving motor is provided in the installation chamber and located at the rear end of the refrigeration chamber; a fixed seat is provided on the inner wall of the refrigeration chamber, a screw rod is pivotally connected to the fixed seat, the screw rod can rotate on the fixed seat, and the end of the screw rod passes through the guide through hole and is connected to the output end of the driving motor; a moving seat is installed on the pull-out drawer, and a driving threaded hole screwed on the screw rod is provided on the moving seat.

[0027] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present utility model in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] As Figures 1 - 3 shown, a sliding structure and a vehicle-mounted refrigerator are provided. The sliding structure includes a fixed bracket 1. A sliding portion 2 extending outward is provided on the fixed bracket 1. A sliding block 3 is provided on the sliding portion 2, and the sliding block 3 slides along the length direction of the sliding portion 2.

[0029] Specifically, the fixed bracket 1 provides a stable supporting structure, and the sliding part 2 extends from the fixed bracket 1 to provide a track for the movement of the sliding block 3, so that the sliding block 3 has a reliable guide during the sliding process, avoiding unstable sliding or shaking of the sliding block 3.

[0030] Further, if Figure 4 As shown, a guide structure 4 is provided between the sliding part 2 and the sliding block 3, and the guide structure 4 includes a guide rib 401 and a guide groove 402, the guide rib 401 is provided on the sliding part 2, and the guide groove 402 is provided on the sliding part 2, and the sliding part 2 slides on the guide rib 401 of the sliding part 2 through the guide groove 402.

[0031] Specifically, the guide rib 401 provided on the sliding part 2 cooperates with the guide groove 402 on the sliding block 3. During the sliding process, the guide groove 402 limits the lateral movement of the sliding block so that it can only slide along the length direction of the sliding part 2, effectively preventing the deviation caused by lateral force or other external force, thereby avoiding shaking and instability during the sliding process.

[0032] Further, if Figure 3 As shown, the guide rib 401 is arranged along the length direction of the sliding part 2.

[0033] Specifically, the length direction setting of the guide rib 401 ensures that the sliding block 3 is restricted during the entire sliding process, preventing the displacement caused by the lateral force, so that the sliding block 3 can only slide along the length direction of the sliding part 2, thereby ensuring the accuracy and stability of the sliding.

[0034] Further, if Figures 2 - 4 As shown, a recess 201 for mounting the sliding block 3 is provided on the sliding portion 2 , and the sliding block 3 is located on the recess 201 .

[0035] Specifically, at least a portion of the sliding block 3 is embedded in the recess 201 during installation. Since the sliding block 3 is surrounded by the recess 201 , it is ensured that the sliding block 3 remains in the designated track during the sliding process, thereby ensuring safety and reliability.

[0036] Further, if Figure 1 and Figure 2 , Figures 5 - 7 As shown, an anti-collision pad 5 is provided on the sliding block 3.

[0037] Specifically, the anti-collision gasket 5 plays a role of buffering and shock absorption, which can effectively prevent the sliding block 3 from directly colliding with other components during the sliding process, and reduce damage and noise caused by impact.

[0038] Further, if Figures 5 - 7As shown, a positioning portion 301 extending upward is provided on the sliding block 3, and the anti-collision gasket 5 is provided on the positioning portion 301.

[0039] Specifically, the positioning portion 301 extends upward from the sliding block 3 to form a protruding structure; the sliding block 3 pushes the latch 701 and the drawer 8 through the anti-collision gasket 5, preventing the sliding block 3 from directly contacting the latch 701 and the drawer 8, and reducing the surface damage of the components caused by frequent operation.

[0040] Furthermore, as Figures 5 - 7 shown, an opening 3011 is provided on the positioning portion 301, a support post 501 is provided on the anti-collision gasket 5, a stepped step 5011 is provided on the support post 501, and the anti-collision gasket 5 is installed on the opening 3011 through the support post 501, and the stepped step 5011 abuts against one end face of the positioning portion 301.

[0041] Specifically, the support post 501 is inserted into the opening 3011 to achieve a tight combination of the anti-collision gasket 5 and the positioning portion 301, ensuring the stable installation of the anti-collision gasket 5 and not easily falling off due to vibration or impact; the stepped step 5011 on the support post 501 abuts against one end face of the positioning portion 301 during installation, providing additional support and positioning functions.

[0042] Furthermore, as Figure 1 、 Figure 2 and Figure 4 shown, a transmission screw 6 is provided on the fixed bracket 1, and a connection hole 302 matching the transmission screw 6 is provided on the sliding block 3. When the transmission screw 6 rotates, it drives the sliding block 3 to slide horizontally on the sliding portion 2.

[0043] Specifically, when the transmission screw 6 rotates, due to the meshing of the threads, the sliding block 3 will slide horizontally along the length direction of the sliding portion 2. By controlling the rotation speed and direction of the transmission screw 6, the moving distance and position of the sliding block 3 can be accurately controlled.

[0044] Furthermore, the sliding block 3 is at least formed by POM material. Specifically, this material has good self-lubricity and wear resistance, and the surface finish is controlled within 0.8μm; it should be noted that the self-lubricating property of the POM material further reduces the noise during operation, extends the service life of the components, and reduces the increase in noise caused by wear.

[0045] Furthermore, as Figure 4 shown, there is a spacing distance a between the sliding portion 2 and the sliding block 3; the spacing distance a is 1mm ≤ a ≤ 5mm.

[0046] Specifically, there is a spacing distance a between the sliding part 2 and the sliding block 3. The spacing distance a ensures that the sliding block 3 can slide smoothly on the sliding part 2 while avoiding direct contact between the two.

[0047] Preferably, the spacing distance a includes 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm. An appropriate spacing distance a can effectively reduce the friction between the sliding part 2 and the sliding block 3, which helps to reduce the resistance generated during the sliding process, make the sliding smoother, and reduce the wear of components caused by friction, thereby extending the service life of the sliding structure.

[0048] As Figure 8 shown, a vehicle-mounted refrigerator includes a vehicle-mounted refrigerator main body 7 and a drawer 8 provided on the vehicle-mounted refrigerator main body 7. The vehicle-mounted refrigerator main body 7 is provided with a lock 701 and a sliding structure for pushing the lock 701 and the drawer 8.

[0049] Specifically, the sliding structure is provided on the vehicle-mounted refrigerator main body 7 and drives the sliding block 3 to slide along the length direction of the sliding part 2 by mechanical or electric means; when the drawer 8 is in the closed state, the lock 701 automatically locks with the drawer to prevent the drawer 8 from accidentally opening due to vibration during vehicle driving; when the sliding block 3 slides along the sliding part 2 and contacts the lock 701, the sliding block 3 pushes open the lock 701 to release the locked state of the drawer 8, so that the sliding block 3 can continue to push the drawer 8 to slide on the vehicle-mounted refrigerator main body 7 to achieve the opening operation of the drawer 8.
