[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] See also Figure 1-Figure 17The double-door car refrigerator comprises a box body 1, a door body 2 and a door lock assembly. The box body 1 has a storage cavity, and the door body 2 can open or close the storage cavity. The front and rear sides of the door body 2 are detachably connected to the box body 1 through the door lock assembly. The door lock assembly comprises a fixed bracket 3, a switch button 4, a spring press 5 and a movable locking rod 6. The fixed bracket 3 is provided with a first limiting portion and a second limiting portion. The switch button 4 and the movable locking rod 6 are respectively slidably connected and cooperated with the first limiting portion and the second limiting portion. By setting two sets of door lock assemblies, the door body 2 can be locked or unlocked from the front or rear direction, so that the way to open the box body 1 with the door body 2 is more flexible, and more different usage scenarios can be realized.

[0039] The fixed bracket 3 can simultaneously limit the switch button 4 and the movable locking rod 6, so that the switch button 4 and the movable locking rod 6 are not prone to accidental displacement during use, thereby improving the stability of the linkage between the switch button 4 and the movable locking rod 6 and reducing the probability of malfunction.

[0040] A linkage mechanism is provided between the switch button 4 and the movable locking rod 6. The movable locking rod 6 can move back and forth along its length direction through the linkage mechanism. The movable locking rod 6 can extend outward and connect with the box body 1 or be retracted inward and separated from the box body 1 to make the door body 2 locked or unlocked. The user only needs to control the switch button 4 to control the activity of the movable locking rod 6 through the linkage mechanism. The user does not need to perform complicated locking or unlocking actions, which simplifies the operation difficulty of the user.

[0041] The switch button 4 is provided with a trigger part 41 for connecting and cooperating with the spring-loaded device 5, and the spring-loaded device 5 has a first use state or a second use state; when the spring-loaded device 5 is in the first use state, the spring-loaded device 5 locks the trigger part 41, and the trigger part 41 drives the switch button 4 to put the door body 2 into an unlocked state; when the spring-loaded device 5 is in the second use state, the spring-loaded device 5 is released and pushes the trigger part 41 to reset, and the trigger part 41 drives the switch button 4 to put the door body 2 into a locked state; each time the trigger part 41 presses the spring-loaded device 5, the spring-loaded device 5 can switch back and forth between the first use state and the second use state, and the spring-loaded device 5 can stabilize the use state of the door body 2 and, at the same time, improve the user's feel when pressing the switch button 4. The specific structure of the spring-loaded device 5 belongs to the prior art, and those skilled in the art can understand the specific structure and working principle of the spring-loaded device 5. Moreover, since the spring-loaded device 5 itself is a component of the prior art, its connection and cooperation structure with the switch button 4 is relatively simple, which simplifies the overall structural layout of the door body 2.

[0042] An anti-drop door connecting rod 7 is provided between the corresponding switch buttons 4 on the front and rear sides of the door body 2, and a limiting mechanism is provided between the anti-drop door connecting rod 7 and the switch button 4, which can limit the maximum relative distance between the two switch buttons 4. The anti-drop door connecting rod 7 can limit the two switch buttons 4 at the same time, thereby preventing the switch buttons 4 from accidentally detaching from the door body 2, thereby improving the safety and stability of the user's operation of the door body 2, and there is no need to additionally set corresponding anti-drop components for the two switch buttons 4, thereby simplifying the overall structure of the equipment and helping to improve installation efficiency.

[0043] Furthermore, the first limiting portion includes an upwardly protruding boss portion 31, the boss portion 31 is provided with a guide groove 311, the switch button 4 is provided with a guide rib 42 corresponding to the guide groove 311, the guide rib 42 and the guide groove 311 are opened along the front-to-back direction, the guide rib 42 and the guide groove 311 are slidably connected and cooperated with each other, so that the switch button 4 can move on the fixed bracket 3 according to the preset running direction.

[0044] A U-shaped hollow cavity 43 is provided on the switch button 4, and corresponding guide ribs 42 are respectively provided on both sides of the inner wall of the hollow cavity 43, and convex column portions 31 are respectively provided at adjacent positions on both sides of the inner wall of the corresponding hollow cavity 43 on the fixed bracket 3. The hollow cavity 43 can better utilize the internal space position of the switch button 4, so that the assembly structure between the switch button 4 and the fixed bracket 3 is more compact and reasonable.

[0045] Furthermore, the trigger portion 41 is arranged on the inner side of the hollow cavity 43, and a limiting cavity corresponding to the spring button 5 is formed between the two convex column portions 31. The convex column portion 31 can also have a certain limiting effect on the spring button 5, thereby improving the stability of the installation structure of the spring button 5 and the fixed bracket 3.

[0046] Furthermore, the second limiting portion includes a limiting groove 32, which is opened along the length direction of the movable locking rod 6. The movable locking rod 6 is embedded in the inner side of the limiting groove 32. The limiting groove 32 can limit the movement direction of the movable locking rod 6, thereby reducing the chance of accidental displacement of the movable locking rod 6.

[0047] A plurality of anti-slip blocks 321 are provided at a position corresponding to the limit groove 32 above the movable locking rod 6. The vertical projection of the anti-slip blocks 321 at least partially overlaps with the movable locking rod 6. The anti-slip blocks 321 can further limit the movable locking rod 6 and prevent the movable locking rod 6 from escaping from the limit groove 32.

[0048] The bottom of the movable locking rod 6 is provided with an avoidance groove 61 opened along its length direction, and the position corresponding to the inner side of the avoidance groove 61 on the limiting groove 32 is provided with a plurality of guide columns 322 distributed along its length direction. The guide columns 322 are adjacent to the avoidance groove 61 to effectively avoid deviation or jamming during the sliding process.

[0049] The left and right sides of the switch button 4 are respectively connected to corresponding movable locking rods 6. The switch button 4 makes the two movable locking rods 6 move synchronously through a linkage mechanism. The left and right sides of the corresponding switch button 4 on the fixed bracket 3 are respectively provided with corresponding second limit parts, so that the connection structure between the door body 2 and the box body 1 of the vehicle refrigerator is more stable.

[0050] Furthermore, the linkage mechanism includes a guide groove 44 and a guide boss 62 respectively arranged on the switch button 4 and the movable lock rod 6. The switch button 4 can move back and forth in a direction perpendicular to the movement of the movable lock rod 6. The guide groove 44 is inclined between the movement directions of the switch button 4 and the movable lock rod 6. The guide boss 62 is inserted into the guide groove 44 and slides with each other. The overall structure of the linkage mechanism is simple and the transmission efficiency is high. The user only needs to press the switch button 4 to control the movable lock rod 6.

[0051] Furthermore, the movable locking rod 6 is connected to a return spring 63. When the movable locking rod 6 is retracted inward, the return spring 63 can be compressed and deformed. The return spring 63 can push the movable locking rod 6 to extend outward, so that the movable locking rod 6 can keep the door body 2 in a locked state. The door body 2 will only be unlocked when it is subjected to the pulling force of the switch button 4.

[0052] The movable locking rod 6 is provided with a limiting boss, and the return spring 63 is at least partially sleeved on the outer side of the limiting boss, thereby improving the stability and accuracy of the connection between the return spring 63 and the movable locking rod 6 and reducing the probability of accidental displacement of the return spring 63.

[0053] The movement of the switch button 4 toward the center position of the door body 2 can cause the movable locking rod 6 to be retracted inward. The end of the guide groove 44 close to the center position of the door body 2 is connected to an extension groove 441 extending toward the center position of the door body 2. The opening direction of the extension groove 441 is parallel to the movement direction of the switch button 4. The reset spring 63 can reset the guide boss 62 to slide and cooperate along the direction of the extension groove 441. After the movable locking rod 6 is reset, the switch button 4 can continue to move in the direction away from the center position of the door body 2 through the push-button 5 without affecting the movable locking rod 6.

[0054] Furthermore, the limiting mechanism includes a limiting long hole 71 and a limiting column 45 respectively arranged on the anti-drop door connecting rod 7 and the switch button 4; when the door body 2 is in an unlocked state, the limiting column 45 abuts or fits adjacent to the limiting long hole 71 on the side close to the corresponding switch button 4; when the door body 2 is in a locked state, the limiting column 45 abuts or fits adjacent to the limiting long hole 71 away from the side of the corresponding switch button 4. The structure of the limiting long hole 71 and the limiting column 45 is relatively simple, not prone to failure, and the stability of the limiting mechanism is ensured.

[0055] An anti-dropout protrusion 451 is provided on the side of the limit column 45 away from the switch button 4 and / or close to the switch button 4. When the limit column 45 abuts against the limit long hole 71, the vertical projection of the corresponding anti-dropout protrusion 451 is at least partially offset from the limit long hole 71. The anti-dropout protrusion 451 can prevent the anti-dropout door connecting rod 7 from accidentally falling off from the limit column 45, thereby further improving the stability of the overall structure of the equipment.

[0056] The maximum stroke of the trigger part 41 pressing the spring 5 is equivalent to the length of the limiting long hole 71, so that the anti-drop door connecting rod 7 can limit the door body 2 and prevent it from dropping out when the door body 2 is locked or unlocked.

[0057] Furthermore, the cross section of the anti-drop door link 7 is in an I-shape, and the left and right sides of the anti-drop door link 7 extend in the up and down directions respectively, which improves the overall structural strength of the anti-drop door link 7 and makes it less likely to deform.

[0058] Furthermore, the movable locking rod 6 includes a rod body 65 and a rod connecting portion 66. The rod body 65 is sleeved on the outside of the rod connecting portion 66 and is slidably connected and cooperated with each other along the circumferential direction. An axial hole 11 corresponding to the rod connecting portion 66 is provided on the box body 1. The switch button 4 can extend the rod connecting portion 66 outward to connect with the axial hole 11 or retract it inward to separate from the axial hole 11 through the linkage mechanism and the rod body 65.

[0059] Furthermore, the cross-sectional shapes of the rod connection part 66 and the shaft hole 11 are respectively in corresponding oblate shapes, and damping oil is filled between the rod body 65 and the rod connection part 66 to form a circumferential damping force between the two. When the user opens the door body 2 on the corresponding side through the switch button 4 on one side, the door body 2 flips around the rod body 65 on the other side. At this time, the rod connection part 66 remains stationary relative to the box body 1. The process of the rod body 65 rotating with the door body 2 can make the door body 2 stay steadily within a certain angle range under the action of the damping oil. Damping oil or other damping structures belong to the prior art, and its working principle and specific structure can be understood by those skilled in the art.

[0060] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments. Those skilled in the art may also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope set by the claims of this application.
