Description

TECHNICAL FIELD

[0001] The present application relates to the field of automotive technology, in particular to a vehicle-mounted refrigerator capable of preventing the refrigerator from being thrown out. BACKGROUND

[0002] With the advent of the era of intelligent vehicles, some trendy changes have taken place in the design of vehicle cabins, such as vehicle-mounted refrigerators, which are usually arranged at the center console and instrument panel to be used by passengers in the front and rear rows.

[0003] Food and beverages are usually placed in the vehicle-mounted refrigerator, and many vehicle-mounted refrigerators can hold 6-8 kg of goods. In addition, the weight of the vehicle-mounted refrigerator itself (from several kilograms to tens of kilograms), the maximum weight that the sliding part of the entire vehicle-mounted refrigerator can withstand is 20-30 kg. Taking the deceleration performance of the vehicle body of most passenger vehicles under the national regulation collision condition as an example, the peak acceleration is usually 30-50 G, and the instantaneous inertia impact force can reach 20 x 300 = 6000 N.

[0004] If the collision occurs when the vehicle-mounted refrigerator is in the closed state, the 6000 N impact force is only borne by the latch and the lock catch. The common plastic material latch and lock catch structure must be particularly large in size, which not only has no sufficient layout space, but also is not aesthetically pleasing. If the strength of the latch and the lock catch is insufficient, there is a risk that the locking mechanism of the vehicle-mounted refrigerator will fail and be pulled out and thrown out.

[0005] If the collision occurs when the vehicle-mounted refrigerator is in the pulled-out state, the vehicle-mounted refrigerator will move relative to the vehicle body. If the passenger's hand is still placed near the refrigerator at this time, the passenger is likely to be injured. If the vehicle is subjected to a rear impact, the 6000 N impact force far exceeds the design strength of the refrigerator slide rail in the front-rear direction, and the refrigerator will be thrown out and injure the passenger. SUMMARY

[0006] The present application provides a vehicle-mounted refrigerator capable of preventing the refrigerator from being thrown out, so that the box body is locked by a secondary locking structure when the vehicle is in a collision, thereby avoiding the box body from being thrown out during the collision.

[0007] The technical solution of the present application to solve the above technical problems is as follows:

[0008] The present application provides a vehicle-mounted refrigerator capable of preventing the refrigerator from being thrown out, so that the box body is locked by a secondary locking structure when the vehicle is in a collision, thereby avoiding the box body from being thrown out during the collision.

[0009] The box body is slidingly connected to the frame skeleton.

[0010] The locking mechanism is arranged on the bottom plate in the frame skeleton and located between the two slide rails, so that the locking mechanism is opened to lock the box body sliding under the action of the inertia force.

[0011] As a further technical solution, the locking mechanism comprises a fixed column, two tension springs, two locking latches, two rotating swing arms, and a locking piece.

[0012] The fixed column is fixedly connected with a tension spring on each side, and the other side of the tension spring is sequentially connected with the locking latch and the rotating swing arm. The two rotating swing arms are coaxially stacked at the end away from the locking latch, so that the fixed column, the tension spring, the locking latch, and the rotating swing arm enclose a space for accommodating the locking piece.

[0013] The rotating arm applies a downward pressure to the top surface of the locking piece. The locking latch is clamped into the locking rack of the box under the action of inertial force, and pulls the tension spring and the rotating swing arm to make the locking piece pop up to lock the opening angle of the two rotating swing arms.

[0014] As a further technical solution, the locking piece comprises a fixed part, a first telescopic spring, and a first locking pin.

[0015] The first telescopic spring and the first locking pin are sequentially connected from bottom to top and are arranged in the accommodating cavity of the fixed part. The upper part of the first locking pin extends out of the upper end surface of the fixed part and abuts against the lower end surface of the rotating arm. The movement of the rotating arm controls the first locking pin to pop out of or pop into the fixed part under the action of the first telescopic spring.

[0016] As a further technical solution, the locking piece further comprises a pull rod, and the first telescopic spring, the pull rod, and the first locking pin are sequentially connected from bottom to top.

[0017] The side wall of the fixed part is provided with a sliding groove along the height direction. One end of the pull rod is slidingly connected to the inner wall of the fixed part, and the other end extends out of the sliding groove. Pulling down the pull rod drives the first locking pin to move downward to restore the initial state of the rotating arm.

[0018] As a further technical solution, the locking mechanism is provided with two and is mirror arranged along the length direction of two sliding grooves.

[0019] As an alternative solution of the locking mechanism, the locking mechanism comprises a housing, and a locking piece and a second telescopic spring arranged in the housing.

[0020] The locking piece is vertically slidingly arranged in the housing. One end of the second telescopic spring is fixedly connected with a side wall in the housing, and the other end is fixedly connected with the outer side wall of the locking piece. The locking piece slides along the length direction of the housing under the action of the second telescopic spring, and extends out of the upper end surface of the housing to be clamped into the locking hole at the bottom of the box.

[0021] The shell is internally provided with a containing cavity, so that the locking member and the second telescopic spring are arranged in the containing cavity.

[0022] As a further technical solution, the locking member comprises a fixing member, a first telescopic spring and a locking pin.

[0023] The first telescopic spring and the locking pin are sequentially connected from bottom to top and are arranged in the containing cavity of the fixing member, so that the locking member moves in the direction of the opening of the upper part of the shell under the action of the inertial force, and the locking pin is clamped into the locking hole of the bottom of the box after being ejected from the opening under the action of the first telescopic spring.

[0024] As a further technical solution, the locking member is further provided with a pull rod, and the first telescopic spring, the pull rod and the locking pin are sequentially connected from bottom to top.

[0025] The side wall of the fixing member is provided with a sliding groove along the height direction thereof, and one end of the pull rod is slidingly connected to the inner wall of the fixing member and the other end extends out of the sliding groove, and the pull rod is pulled downward to drive the locking pin to move downward to restore the initial state between the box and the frame skeleton.

[0026] The shell is provided with an opening groove corresponding to the sliding groove, so that the pull rod extends out of the shell from the opening groove.

[0027] As a further technical solution, the locking mechanism is provided with two and is arranged side by side along the width direction of the two sliding grooves.

[0028] The beneficial effects of the present application are that the locking mechanism is simple in structure and can be arranged between the box and the frame skeleton, does not occupy the original space, is reasonable in layout and beautiful in appearance.

[0029] When the car does not collide, the locking mechanism is always located between the box and the frame skeleton and does not affect the normal use of the car refrigerator, when the car collides, the locking mechanism is opened by the inertial force generated in the collision process, the box is clamped to avoid the movement of the box relative to the frame skeleton, and then the box is prevented from being thrown out of the frame skeleton to affect the safety of the passengers in the car.

[0030] In addition, the original state of the car refrigerator when it is closed can be restored by pulling the pull rod to move the box into the frame skeleton. BRIEF DESCRIPTION OF DRAWINGS

Therefore, the present application is not intended to be limited to the shown embodiments, but is consistent with the broadest scope of principles and features disclosed in the present application.

[0056] A common refrigerator opening way is drawer type, usually two or three section rail type. Because the current regulations collision experiment in the evaluation of vehicle occupant protection safety, the default experimental conditions are that the vehicle-mounted drawer refrigerator is in the closed state, and there is no food and beverage in the vehicle-mounted refrigerator to represent the actual use scene. Under this experimental condition, as long as the structure strength of the locking tongue of the vehicle-mounted refrigerator is slightly increased when it is closed, it can meet the experimental requirements;

[0057] But in the actual use scene, food and beverages are usually placed in the vehicle-mounted refrigerator, so that when the car collides, the design strength of the vehicle-mounted refrigerator in the front and rear direction cannot meet the strength required by the vehicle-mounted refrigerator at this time, that is, the locking mechanism of the vehicle-mounted refrigerator fails at this time, so that the vehicle-mounted refrigerator is thrown out and hurts the vehicle occupants.

[0058] Embodiment 1

[0059] The present embodiment provides a vehicle-mounted refrigerator to solve the above-mentioned defects, referring to Figure 1 、 Figure 3 , specifically comprising a box body 1, a frame skeleton 2, and a locking mechanism; the box body 1 is slidingly connected in the frame skeleton 2; the locking mechanism is arranged on the bottom plate 21 in the frame skeleton 2 and located between the two slide rails 22, so that the locking mechanism is opened under the action of the inertial force to lock the sliding of the box body 1, that is, when the car collides, the box body 1 is easy to slide out of the frame skeleton 2, but due to the structural design of the locking mechanism, the box body 1 can be blocked from completely sliding out of the frame skeleton 2, thereby avoiding the box body 1 from being thrown out of the frame skeleton 2 under the action of the inertial force generated during the collision, and timely locking the high-speed sliding of the box body 1 relative to the vehicle body. When the vehicle does not collide, the locking mechanism installed on the frame skeleton 2 of the auxiliary instrument panel does not work (at this time, it will not affect the normal use of the vehicle-mounted refrigerator);

[0060] Embodiment 2

[0061] Based on the content of embodiment 1:

[0062] Referring to Figures 2-10The arresting mechanism comprises a fixed column 3, two tension springs 4, two locking latches 5, two rotating swing arms 6, and a locking piece 7. The fixed column 3 is fixedly connected with a tension spring 4 on each side, and the other side of the tension spring 4 is sequentially connected with the locking latch 5 and the rotating swing arm 6. The two rotating swing arms 6 are coaxially and laminatedly arranged at the end away from the locking latch 5, so that the fixed column 3, the tension spring 4, the locking latch 5, and the rotating swing arm 6 enclose a space for accommodating the locking piece 7. The locking piece 7 is vertically arranged in the space. When the arresting mechanism is in an idle state, the tension spring 4 is in a free extension state, and the rotating swing arm 6 applies a downward pressure to the top end surface of the locking piece 7, so that the upper end surface of the locking piece 7 is below the bottom end surface of the rotating swing arm 6. When the automobile is in a collision, when the deceleration or acceleration reaches a certain threshold value, the inertial force acting on the locking latch 5 is greater than the tension of the tension spring 4, so that the locking latch 5 is clamped into the locking rack 11 of the box body 1 under the action of the inertial force. At this time, the locking latch 5 pulls the tension spring 4 and the rotating swing arm 6 to move away from the locking piece 7, so that the locking piece 7 is not pressed and is bounced upward to lock the opening angle of the two rotating swing arms 6. In this process, the two rotating swing arms 6 rotate along the connected shaft.

[0063] The two rotating swing arms 6 are coaxially arranged on a vertical shaft 61, and the two rotating swing arms 6 are laminatedly arranged, so that the two rotating swing arms 6 can rotate in the horizontal direction along the vertical shaft 61, that is, the included angle between the two rotating swing arms 6 is reduced or enlarged.

[0064] More specifically, the cross section of the locking latch 5 is configured in a 7 type, and the tension spring 4 is fixedly connected to the outer side wall of the 7 type. The end edge of the 7 type is clamped on the locking rack 11 of the box body 1, so as to complete the locking of the vehicle-mounted refrigerator, thereby avoiding the relative sliding of the box body 1 relative to the frame skeleton 2.

[0065] In the specific implementation process, reference can be made to Figure 9 , Figure 10The locking member 7 comprises a fixing member 71, a first telescopic spring 72, and a locking pin 73. In this embodiment, the external profile of the locking member 7 can be a hollow cylindrical type or a hollow cuboid type, which is not limited herein. The first telescopic spring 72 and the locking pin 73 are sequentially connected from bottom to top and are both arranged in the accommodating cavity of the fixing member 71. The upper part of the locking pin 73 extends out of the upper end surface of the fixing member 71 and abuts against the lower end surface of the rotary swing arm 6. The movement of the rotary swing arm 6 controls the locking pin 73 to be ejected or retracted from the fixing member 71 under the action of the first telescopic spring 72. That is, when the automobile does not collide, the locking pin 73 does not work under the action of the pulling force of the first telescopic spring 72 and the downward pressure applied by the rotary swing arm 6. When the automobile collides, under the action of the inertial force, the locking clamping tongue 5 is pulled by the inertial force generated when the automobile collides, which is smaller than the pulling force of the tension spring 4. As a result, the locking clamping tongue 5 simultaneously pulls the tension spring 4 and the rotary swing arm 6 to move away from the locking member 7. On the one hand, the locking clamping tongue 5 is clamped into the locking rack 11 of the box body 1 (that is, the spacing between the two adjacent locking racks 11 on the box body 1 is adapted to the clamping end of the locking clamping tongue 5). On the other hand, the locking member 7 loses the restraint, the first telescopic spring 72 lifts the locking pin 73 to move upward, so as to fix the opening angle of the two rotary swing arms 6 at this time.

[0066] In the specific implementation process, in order to facilitate the box body 1 to restore the initial state after being thrown out, referring to Figure 9 、 Figure 10 The locking member 7 further comprises a pull rod 74, which is sequentially connected with the first telescopic spring 72 and the locking pin 73 from bottom to top. The side wall of the fixing member 71 is provided with a sliding groove 711 along the height direction thereof. One end of the pull rod 74 is slidingly connected to the inner wall of the fixing member 71, and the other end extends out of the sliding groove 711. The pull rod 74 is pulled downward to drive the locking pin 73 to move downward, so as to restore the initial state of the rotary swing arm 6. At this time, the locking clamping tongue 5 is pulled away from the locking rack 11 of the box body 1 under the joint action of the tension spring 4 and the rotary swing arm 6. At the same time, the locking clamping tongue 5 applies a downward pressure to the locking pin 73, and the locking pin 73 applies a downward pressure to the first telescopic spring 72, so that the first telescopic spring 72 is compressed, and then the initial state of the sliding connection between the box body 1 and the frame skeleton 2 is completed.

[0067] In the specific implementation process, in order to lock the relative sliding of the box body 1 relative to the frame skeleton 2 in time when the drawer refrigerator is in a half-open state, whether the front collision or the rear collision occurs, the locking mechanism is provided with two and is mirror arranged along the length direction of the two slide rails 22, that is, two locking mechanisms are mirror arranged along the length direction of the two slide rails 22 in the middle of the two slide rails 22 in the frame skeleton 2.

[0071] The locking piece 7 comprises a fixing piece 71, a first telescopic spring 72 and a locking pin 73, and the external contour of the locking piece 7 in this embodiment can be a hollow cylindrical type or a hollow cuboid type, which is not limited here.

[0072] The first telescopic spring 72 and the locking pin 73 are sequentially connected from bottom to top and are arranged in the accommodating cavity of the fixing piece 71, so that the locking piece 7 moves in the direction that the opening 82 is opened in the upper part of the shell 8 under the action of the inertial force, and the locking pin 73 is clamped into the locking hole 12 at the bottom of the box body 1 under the action of the first telescopic spring 72 after being popped out of the opening 82.

[0073] In more detail, the locking pin 73 in the locking piece 7 is sequentially popped out of the upper end of the locking piece 7 and the shell 8, passes through the bottom plate 21 of the frame skeleton 2 and is clamped into the locking hole 12 at the bottom of the box body 1, and the locking hole 12 is adapted to be plugged with the locking piece 7. Among them, the shell 8 and the locking piece 7 are both provided with accommodating cavities, and the locking piece 7 and the second telescopic spring 81 are arranged in the accommodating cavity where the shell 8 is located, when the car does not collide, the locking mechanism does not work, and at the same time, it does not affect the normal use of the refrigerator on the car;
