DETAILED DESCRIPTION

[0044] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0045] like Figures 1 to 11As shown, the utility model is a car refrigerator with a self-priming function, comprising: a fixed base 1; a drawer 2, which is slidably arranged on the fixed base 1 and has a closed position, a self-priming position and a maximum expanded position; a self-priming unit 3, which is arranged on the fixed base 1 and has a track groove 4 and a sliding block 5, the track groove 4 has a straight section 6 and a bending section 7, one end of the sliding block 5 is movably inserted in the straight section 6 and movably engaged with the bending section 7, and the other end is movably engaged with the drawer 2; the sliding block 5 can be disengaged from the drawer 2 because one end of the sliding block 5 inserted in the track groove 4 moves from the straight section 6 to the bending section 7, and can be restored to the engagement with the drawer 2 because the drawer 2 moves from the maximum expanded position to the self-priming position, and is used to drive the drawer 2 to move from the self-priming position to the closed position; a first driving unit 8, which is arranged on one side of the fixed base 1, is used to drive the drawer 2 to disengage from the sliding block 5; a second driving unit 9, which is arranged on the fixed base 1, is used to drive the drawer 2 to move to the maximum expanded position.

[0046] The specific steps for moving the drawer 2 from the closed position to the maximum expanded position are as follows: the first drive unit 8 is started, driving the drawer 2 to slide along the fixed seat 1, thereby driving the sliding block 5 engaged with the drawer 2 to move along the track groove 4 until the sliding block 5 moves along the straight section 6 to the bending section 7. At this time, one end of the sliding block 5 is engaged with the bending section 7 and is fixed on the track groove 4, and the other end is disengaged from the drawer 2. Then, the first drive unit 8 stops driving the drawer 2, and the second drive unit 9 is started to continue to drive the drawer 2 to move until the drawer 2 slides to the maximum expanded position on the fixed seat 1.

[0047] When the drawer 2 is in the self-priming position and the self-priming unit 3 is started, the manual pushing of the drawer 2 can be stopped. The sliding block 5 is driven by the self-priming unit 3 to resume the engagement with the drawer 2 and continue to move along the straight section 6 on the track groove 4, while driving the drawer 2 to slide on the fixed seat 1 to the closed position, thereby ensuring that the car refrigerator is sealed. During this operation, it is only necessary to manually push the drawer 2 to the self-priming position, and the self-priming unit 3 can drive the drawer 2 to the closed position. This mechanism not only simplifies the user's operating process and reduces the problem of poor sealing caused by human negligence, but also improves the energy efficiency of the refrigerator and reduces energy consumption, because reduced loss of cold air means that the refrigerator does not need to be started frequently to maintain the set temperature.

[0048] Specifically, the self-priming unit 3 also includes: a support seat 10, which is arranged on the fixed seat 1, and the track groove 4 is arranged on the support seat 10; a first movable seat 11, which is movably connected to the support seat 10, and the sliding block 5 is rotatably connected to the first movable seat 11; a first elastic member, a first elastic member is arranged on both sides of the support seat 10, one end of the first elastic member is connected to the support seat 10 and the other end is connected to the first movable seat 11, and the first elastic member is preferably a tension spring.

[0049] like Figure 7 and Figure 8 The drawer 2 shown is in the closed position, and the first drive unit 8 drives the drawer 2 in the closed position, thereby driving the sliding block 5 engaged with the first fixed block 12 to move synchronously. At this time, the first movable seat 11 moves relative to the support seat 10 under the drive of the sliding block 5, and the first elastic members on both sides are stretched and elastically deformed. When the sliding block 5 moves from the straight section 6 on the track groove 4 to the bending section 7, one end of the sliding block 5 is engaged with the bending section 7, and the other end is disengaged from the first fixed block 12, so that the sliding block 5 is fixed on the track groove 4, the first movable seat 11 stops moving, and the first elastic member is stretched to store potential energy.

[0050] like Figure 11 The drawer 2 is shown in the maximum extended position. The drawer 2 in the maximum extended position is manually pushed to slide on the fixed seat 1. At this time, the sliding block 5 is fixed on the track groove 4 and is located on the moving path of the drawer 2. The drawer 2 is manually pushed and abuts against one end of the sliding block 5 and drives the other end of the sliding block 5 to disengage from the bent section 7. At this time, the force pulling the first elastic member to cause elastic deformation disappears, and the drawer 2 is in the self-priming position. Figure 9 and Figure 10 As shown, stop manually pushing the drawer 2, the first elastic member restores its elastic deformation to drive the first movable seat 11 closer to the support seat 10, and as the first movable seat 11 moves, the sliding block 5 connected to the first movable seat 11 moves synchronously and re-engages with the drawer 2, thereby driving the drawer 2 to slide on the fixed seat 1 to the closed position.

[0051] In order to allow the drawer 2 to be movably engaged with the sliding block 5, a first fixed block 12 is provided on the drawer 2, and the first fixed block 12 has a first card slot 13 and a guide slot 14 connected to the first card slot 13. The sliding block 5 has a first end movably inserted into the track slot 4 and a second end movably engaged with the drawer 2. The second end can slide into or out of the first card slot 13 along the guide slot 14, thereby realizing engagement or disengagement with the first fixed block 12.

[0052] like Figure 7 and Figure 8As shown, the drawer 2 is in the closed position, the second end of the sliding block 5 is engaged in the first slot 13, and when the drawer 2 is driven by the first driving unit 8 to slide along the fixed seat 1 to the maximum open position, the sliding block 5 engaged with the first fixed block 12 is driven to move synchronously, so that the first end slides along the track groove 4, and when the first end moves along the straight section 6 to the bending section 7, the sliding block 5 rotates relative to the first movable seat 11, so that the second end slides out of the first slot 13 along the guide groove 14, and the first end is engaged in the bending section 7, and the sliding block 5 is disengaged from the first fixed block 12 and is fixed on the track groove 4; the drawer 2 is in the maximum open position. When the large expanded position is manually pushed to slide along the fixed seat 1 to the self-priming position, the sliding block 5 is fixed on the track groove 4 and is located on the moving path of the drawer 2. The drawer 2 slides to the position of the sliding block 5 under manual push. At this time, the first fixed block 12 is located above the second end, and the drawer 2 continues to slide. The second end abuts against one side of the guide groove 14, so that the sliding block 5 rotates relative to the first movable seat 11 under the drive of the first fixed block 12, and the first end is disengaged from the bending section 7. The self-priming unit 3 is immediately activated, and the drawer 2 is in the self-priming position. The second end slides into the first card slot 13 along the guide groove 14.

[0053] Specifically, the first drive unit 8 includes a drive member 15, which is arranged on the side of the fixed base 1. A push rod 16 is provided at the output end of the drive member 15. The push rod 16 is movably abutted against the drawer 2. The drive member 15 drives the drawer 2 to move through the push rod 16. The drive member 15 is preferably a motor.

[0054] Specifically, the second driving unit 9 includes: a second movable seat 17, on which a pushing member 18 is provided, and a second fixed block 19 is provided on the drawer 2. The pushing member 18 abuts against the second fixed block 19, and the second movable seat 17 drives the drawer 2 to move through the pushing member 18; a second elastic member 20, and two second elastic members 20 are provided on the fixed seat 1, one end of the second elastic member 20 is connected to the fixed seat 1, and the other end is connected to the second movable seat 17; when the drawer 2 is in the closed position, the second elastic member 20 is stretched and elastically deformed. When the driving member 15 pushes the drawer 2 to slide through the pushing rod 16, the second elastic member 20 restores the elastic deformation and drives the second movable seat 17 to move. The pushing member 18 connected to the second movable seat 17 keeps abutting against the drawer 2 and moves synchronously. Subsequently, the drawer 2 is disengaged from the sliding block 5, and the force generated by the first elastic member on the drawer 2 through the sliding block 5 disappears. The second elastic member 20 continues to drive the second movable seat 17 to move, so that the pushing member 18 drives the drawer 2 to move to the maximum expanded position through the second fixed block 19.

[0055] The second elastic member 20 is preferably a coil spring. When the second elastic member 20 restores its elastic deformation, the force it exerts on the drawer 2 is along the opening direction of the drawer 2, and is opposite to the direction of the force exerted on the drawer 2 when the first elastic member restores its elastic deformation. It is worth noting that when the drawer 2 is in the self-priming position, the force of the first elastic member is greater than the force of the second elastic member 20, which means that the first elastic member can overcome the resistance of the second elastic member 20, and drive the drawer 2 to automatically move to the closed position through the first movable seat 11 and the sliding block 5 without the need for external force intervention.

[0056] In order to fix the drawer 2 when it is in the closed position, a fixing unit 21 is further provided on the fixing base 1.

[0057] Specifically, the fixing unit 21 includes: a support rod 22, which is arranged on the support base 10; a clamping piece 23, which is rotatably arranged on the support rod 22, and a clamping block 24 is provided on the drawer 2, the clamping piece 23 is movably clamped with the second fixed block 19, and one end is movably abutted against the push rod 16; a torsion spring 25, the torsion spring 25 is sleeved on the support rod 22 and is located on the side of the clamping piece 23, one pin of the torsion spring 25 is fixed on the support, and the other pin is abutted against the clamping piece 23.

[0058] When the drawer 2 is in the closed position, the latching piece 23 is engaged with the latching block 24, and the driving piece 15 drives the pushing rod 16 to movably abut against one end of the latching piece 23 and push the latching piece 23 to rotate, so that the other end of the latching piece 23 is disengaged from the drawer 2. At this time, the torsion spring 25 is compressed and elastically deformed, and the driving piece 15 continues to drive the pushing rod 16 to separate from the latching piece 23 and abut against one side of the drawer 2. The pushing rod 16 pushes the drawer 2 to move under the push of the driving piece 15 until the drawer 2 is disengaged from the sliding block 4. At the same time, the torsion spring 25 recovers its elastic deformation and drives the latching piece 23 to rotate back to its initial position.

[0059] Furthermore, the clamping member 23 is provided with a second clamping groove 26 and a guide slope 27. The second clamping groove 26 is used for the clamping member 23 to be clamped with the clamping block 24, and the guide slope 27 is used for the clamping block 24 to slide into the second clamping groove 26. When the drawer 2 is driven by the self-priming unit 3 to slide along the fixed seat 1, the clamping block 24 moves synchronously with the drawer 2. Driven by the drawer 2, the clamping block 24 contacts the guide slope 27 and slides along the guide slope 27. During this process, one pin of the torsion spring 25 is stretched and elastically deformed. When the drawer 2 moves to the closed position, the clamping block 24 just slides over the guide slope 27. At the same time, the torsion spring 25 restores its elastic deformation to drive the second clamping groove 26 to be clamped with the clamping block 24, and the drawer 2 is fixed in the closed position.

[0060] In order to provide fixation for the drawer 2 when it is in the maximum expanded position, a third elastic member 28 is also provided on the fixing seat 1, and a circular arc-shaped protrusion 29 is provided at one end of the third elastic member 28. A third card groove 30 is provided on one side of the first fixed block 12. The third elastic member 28 is located on the moving path of the drawer 2. When the drawer 2 is pushed by the second driving unit 9, the first fixed block 12 moves synchronously. When the drawer 2 reaches the maximum expanded position, the third card groove 30 on the first fixed block 12 is engaged with the circular arc-shaped protrusion 29, thereby achieving fixation of the drawer 2. The third elastic member 28 is preferably a spring clip.

[0061] In order to prevent the second drive assembly from driving the drawer 2 to move too fast, a damping member is also included. The damping member has a gear 31 and a rack 32 meshing with the gear 31. The gear 31 is rotatably set on the second movable seat 17, and the rack 32 is set on the fixed seat 1. When the second elastic member 20 restores its elastic deformation to drive the second movable seat 17 to move, the gear 31 slides along the rack 32, and the friction between the two produces a damping effect, thereby slowing down the speed at which the drawer 2 moves to the maximum expanded position, ensuring that the drawer 2 can reach its maximum expanded position smoothly and slowly, avoiding impact or damage that may be caused by rapid movement.

[0062] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0063] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0064] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0065] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0066] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the scope defined by the spirit of the present invention.
