Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a vehicle-mounted refrigerator which can be pushed and closed. Background Art

[0002] The applicant has applied for a rope-driven car refrigerator with application number 2022221584629. This type of refrigerator requires a rope to drive the drawer to open and close. The rope needs to be tightened to drive the drawer to move smoothly. In the traditional method, the rope is completely tightened and rigid, which results in the need to open and close it through independent switches. However, users still tend to close the drawer by pushing the drawer. In the original technology, it is impossible to drive the pull-out drawer to move by external force. First, the rope reel has a great control force on the rope, and it is basically impossible for the user to overcome the force of the rope reel to push the pull-out drawer. Second, if the external force is too large and causes the drawer to move, it will inevitably cause the rope to move as a whole. When the motor is not working, the rope moves on the rope reel, which will cause damage to the rope reel. Utility Model Content

[0030] Reference Figures 1 to 6 , a push-to-close vehicle refrigerator, comprising:

[0031] A refrigerator body 10, wherein a cold chamber 11 is disposed in the refrigerator body 10, an opening communicating with the cold chamber 11 is disposed on the surface of the refrigerator body 10, and a winding member 50 is disposed in the cold chamber 11;

[0032] A drawer 20, wherein the drawer 20 is movably inserted into the cold chamber 11 along the opening, a mounting position located at the rear end of the winding member 50 is provided on the surface of the drawer 20, and a trigger member is provided on the drawer 20;

[0033] A rope drum 30, the rope drum 30 is arranged on the refrigerator body 10, the rope drum 30 is provided with a rope 31 and a motor for driving the rope 31 to reciprocate, the rope 31 is wound on the winding member 50 to form a ring, the rope 31 is installed on the installation position, and the rope 31 is provided with a tension spring 40 for straightening the rope 31;

[0034] A sensing element is disposed at the front end of the cold chamber 11 , and cooperates with a trigger to determine the movement state of the drawer 20 .

[0035] The rope 31 is changed from rigid to elastic by tightening the spring 40. The user normally drives the rope drum 30 to move through the motor, thereby driving the drawer 20 to open. At this time, the trigger moves synchronously with the drawer 20. Then, when the user needs to close the drawer 20, the user pushes the drawer 20. Due to the existence of the tightening spring 40, the drawer 20 can be displaced to a certain extent without driving the rope drum 30 to operate through the rope 31. At the same time, the displacement of the drawer 20 will drive the trigger to trigger the sensing element. After the user lets go, the drawer 20 will reset under the action of the tightening spring 40. The motor drives the rope drum 30 to work under the signal generated by the trigger element, and then drives the drawer 20 to retract into the cold chamber 11. Through this solution, the rope 31 type car refrigerator can close the drawer 20 by pushing the drawer 20, which is more suitable for the user's usage habits.

[0036] In this solution, considering the concealment and rationality of the layout, it is preferred that the trigger member is disposed at the bottom of the drawer 20 , and the sensing element is disposed at the bottom surface of the cold chamber 11 .

[0037] In this solution, the trigger is preferably a collision table 21 disposed on the surface of the drawer 20, and the sensing element is a moment switch 70 disposed in the cold chamber 11. When the drawer 20 is fully opened, the collision table 21 abuts against the moment switch 70 and triggers the moment switch 70. In this embodiment, when the drawer 20 is fully opened, the collision table 21 triggers the moment switch 70, indicating that the drawer 20 is in a fully opened state at this time. When the user pushes the drawer 20, the collision table 21 moves backward to reset the moment switch 70. At this time, the system determines that the user is performing a closing operation, thereby driving the rope drum 30 to rotate through the motor, thereby closing the drawer 20.

[0038] In the present embodiment, the installation position is preferably a front installation groove 22 and a rear installation groove 23 arranged at the bottom of the drawer 20, and the two ends of the rope 31 are respectively installed in the front installation groove 22 and the rear installation groove 23 along the front-to-back direction. There are two tensioning springs 40, and the front ends of the two tensioning springs 40 are respectively fixed to the ends of the rope 31, and the ends of the two tensioning springs 40 are respectively abutted against the inner walls of the front installation groove 22 and the rear installation groove 23 to straighten the rope 31. Under this structure, when the user pushes the drawer 20 to make a short displacement, the drawer 20 moves toward the inside of the cold chamber 11, thereby driving the front mounting groove 22 and the rear mounting groove 23 to move backward. At this time, the rope 31 is in a completely motionless state, so that the distance between the end of the rope 31 located in the front mounting groove 22 and the front end surface of the front mounting groove 22 is reduced, thereby compressing the tensioning spring 40, and the distance between the end of the rope 31 located in the rear mounting groove 23 and the rear end surface of the rear mounting groove 23 is increased, thereby releasing the tensioning spring 40. Therefore, through the compression and release of the two tensioning springs 40, the rope 31 can cause a certain displacement of the drawer 20 without moving.

[0039] In this embodiment, the collision platform 21 is preferably arranged at the bottom of the drawer 20 and protrudes downward, and the front mounting groove 22 and the rear mounting groove 23 are both arranged on the bottom surface of the collision platform 21. By arranging the collision platform 21 and the front mounting groove 22 and the rear mounting groove 23 in one body, the overall structure can be simplified.

[0040] For further optimization, in the rope 31 type vehicle refrigerator, in order to position the drawer 20 when the drawer 20 is fully opened and fully closed, a front stop platform 60 and a rear stop platform 61 are provided on the bottom surface of the cold chamber 11. On this basis, the moment switch 70 is preferably provided on the rear end surface of the front stop platform 60, and the collision platform 21 can abut against the surfaces of the front stop platform 60 and the rear stop platform 61 during movement. When the drawer 20 is fully opened, the collision platform 21 hits the front stop platform 60 and triggers the moment switch 70. When the drawer 20 is fully closed, the collision platform 21 hits the rear stop platform 61, thereby confirming that the drawer 20 is in a fully closed state.

[0041] In this solution, a mounting cavity is preferably provided in the middle of the front stop platform 60 , and the momentary switch 70 includes a switch body and a switch contact. The switch body is provided in the mounting cavity and the switch contact is located at the rear end surface of the front stop platform 60 .

[0042] For further optimization, in order to reduce the vibration and noise generated when the collision platform 21 hits the front stop platform 60, the front stop platform 60 is preferably provided with a shock-absorbing sleeve 80 on the outer periphery, and the shock-absorbing sleeve 80 is provided with a shock-absorbing hole 81 located on the rear side of the front stop platform 60, and the switch contact extends into the shock-absorbing hole 81.

[0043] In other embodiments, the inching switch 70 may also be directly welded to the rear end surface of the front stop platform 60 , or fixed to the top of the front stop platform 60 .

[0044] In this solution, it is preferred that a mounting seat is detachably provided at the bottom of the cold chamber 11, the sensing element and the winding member 50 are both arranged on the surface of the mounting seat, a fixed slide rail is provided on the mounting seat, and a movable slide rail cooperating with the fixed slide rail is provided on the drawer 20, so that it is convenient for installation and easy to control the stability of the drawer 20 during the opening and closing process.

[0045] The tension spring 40 may also be arranged as follows in other embodiments: the rope 31 includes a front rope segment and a rear rope segment extending from the rope drum 30, the front rope segment is divided into a first front rope and a second front rope, the tension spring 40 is located between the first front rope and the second front rope and is used to connect the first front rope and the second front rope, the end of the rear rope segment is connected to the installation position, the end of the second front rope is connected to the installation position, and the front lock segment is wound on the winding member 50. Under this structure, when the drawer 20 is pushed, the second front rope will move inward synchronously with the drawer 20, while the first front rope will not move because it is installed on the rope drum 30. At this time, the first front rope and the second front rope will stretch the tension spring 40, so that the drawer 20 can be displaced to a certain extent.

[0046] In other embodiments, the trigger is an induction magnet provided on the drawer 20, and the induction element is a Hall sensor cooperating with the induction magnet. When the drawer 20 is opened, the magnet moves toward the Hall sensor, and it is judged to be in an open state at this time. When the user pushes the drawer 20 to move a small distance into the cold chamber 11, the magnet moves away from the Hall sensor, thereby judging that the user is performing a door closing operation, so that the rope drum 30 works to drive the rope 31 to move, thereby closing the drawer 20.

[0047] In other embodiments, the trigger is a scale disposed on the surface of the drawer 20, and the sensing element is a position identifier disposed on the inner wall of the cold chamber 11 and facing the scale. The position identifier identifies the scale signal facing it to determine whether to perform the door closing operation.

[0048] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
