Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, and more specifically to a vehicle refrigerator and a vehicle. Background Technology

[0002] As pre-installed embedded car refrigerators become increasingly popular, users have higher and higher requirements for the door opening experience of car refrigerators.

[0003] Most flip-door refrigerators on the market currently use either magnetic closure or button-operated mechanical latch locking mechanisms. Magnetic closure requires maximum force to open and can result in a bumpy, unpleasant user experience when closing. Button-operated mechanical latch locking mechanisms require additional space and, when closing, provide a linear force response with no noticeable tactile feedback. Even the few car refrigerators with push-to-lock flip doors currently offer a linear force response with no distinct tactile feedback when opening and closing. Summary of the Invention

When the door assembly is fully closed, the lock hook and latch engage, and the force feedback elastic structure rebounds outward due to its elastic restoring force, providing a clear "click" tactile feedback so that the user can perceive that the door is locked.

[0043] When the user unlocks and pulls the door assembly, the force feedback elastic structure is compressed and deformed again until the door assembly detaches from the contact surface of the frame assembly. The rebound effect of the force feedback elastic structure can assist the door assembly to open slightly, reducing opening resistance, while providing soft tactile feedback and improving the user experience.

Detailed Implementation

[0074] This utility model embodiment provides a car refrigerator with optimized door opening feel. When opening or closing the car refrigerator, the user will feel the resistance increase to a certain peak and then decrease instantly, which indicates that the car refrigerator is open or closed in place.

[0075] Reference Figure 1 , Figure 2 and Figure 4 This application provides a vehicle-mounted refrigerator, including:

[0076] The box frame assembly 200 has an opening and a latch 212.

[0077] The door assembly 100 is rotatably connected to the box frame assembly 200 and is used to close the opening or expose the opening. The door assembly 100 is provided with a locking hook 180 for locking with the latch 212.

[0078] A door seal 150 is installed on the side of the door assembly 100 facing the box frame assembly 200;

[0079] At least one force feedback elastic structure 153 is formed in the main structure of the door seal 150, and the force feedback elastic structure 153 has a cavity on the side opposite to the box frame assembly 200.

[0080] The frame assembly 200 has an opening for storing and retrieving items. The door assembly 100 is rotatably connected to the frame assembly 200 and can be rotated to close or expose the opening.

[0081] The latch 212 provided on the box frame assembly 200 is used to engage with the latch 180 on the door assembly 100 for locking.

[0082] The main structure of the door seal 150 is made of elastic materials (such as silicone or rubber), which has good deformation recovery ability.

[0083] In this embodiment, the force feedback elastic structure 153 can be configured into different shapes as needed, such as bowl-shaped, funnel-shaped, and hourglass-shaped.

[0084] Since each force feedback elastic structure 153 has a cavity on the side away from the box frame assembly 200, the force feedback elastic structure 153 can collapse inward when compressed and rebound after the pressure is released.

[0085] When the user pushes the door assembly 100 to close, the contact surfaces of the door seal 150 and the frame assembly 200 gradually come into contact. As the door assembly 100 continues to close, the force feedback elastic structure 153 is compressed by the frame assembly 200, the cavity is compressed, and the force feedback elastic structure 153 collapses inward, generating a certain amount of resistance. When the door assembly 100 is fully closed, the lock hook 180 engages with the lock latch 212, and the force feedback elastic structure 153 rebounds outward due to the elastic restoring force, providing a clear "click" tactile feedback so that the user can perceive that the door has been locked.

[0086] When the user unlocks and pulls the door assembly 100, the force feedback elastic structure 153 is compressed and deformed again until the door assembly 100 disengages from the contact surface of the frame assembly 200. The rebound effect of the force feedback elastic structure 153 can assist the door assembly 100 to open slightly, reduce opening resistance, and provide a soft tactile feedback, improving the operating experience.

[0087] In this embodiment, the force feedback elastic structure 153 of the door seal 150 adopts a gradient design with the largest diameter at the top cavity, the gradually decreasing diameter at the middle cavity, and the smallest diameter at the bottom cavity. This design achieves more precise control over the pressing feel. The top cavity is located near the opening side of the force feedback elastic structure. The gradually decreasing diameter of the middle cavity causes the resistance to increase non-linearly with the pressing depth. The smallest diameter of the bottom cavity (the innermost cavity) creates a noticeable "breakthrough feeling" at the end of the pressing process, resulting in a sudden decrease in resistance. Consequently, it creates, for example... Figure 3 The curve shown; in Figure 3 When opening the car refrigerator, the user can feel the aforementioned "breakthrough sensation" when pressing the top cover 110 of the door and the pressing distance reaches a1; when closing the car refrigerator, the user can also feel the aforementioned "breakthrough sensation" when pressing the top cover 110 of the door and the pressing distance reaches a2.

[0088] When pressed, the door seal 150 contacts the frame assembly 200. Because the diameter of the force feedback elastic structure 153 gradually decreases from the top cavity side to the bottom cavity side, the curvature of the sidewall of the middle cavity of the force feedback elastic structure 153 increases, and the deformation resistance gradually increases, forming a clear "force increase" feedback. When the middle cavity of the force feedback elastic structure 153 is completely pressed into the top cavity, the structural stiffness of the force feedback elastic structure 153 reaches a critical point; subsequently, the sidewall of the middle cavity rapidly buckles and collapses, the resistance drops sharply, producing a confirmation sensation similar to a "switch button". The gradual diameter design of the cavity of the force feedback elastic structure 153 makes the pressing process present a three-stage feedback of "light → heavy → sudden release", improving operational accuracy; after the cavity collapses, it can still maintain the overall compression of the door seal, without affecting the airtightness of the enclosure.

[0089] Reference Figures 4-16 The door assembly 100 in this embodiment includes:

[0090] The door cover 110 has a pressing indicator mark on its outer surface;

[0091] The lower cover 130 of the door is fastened to and fixed to the upper cover 110 of the door;

[0096] The foam layer 120 is formed in the lower cover 130 of the door body by foaming through a bare foaming process to form an insulation layer and enhance the heat insulation performance.

[0097] Combination Figure 6 , Figure 13 and Figure 14 After the foam layer 120 is foamed in the lower cover 130 of the door body through the bare foaming process, the magnet 190 is installed in the first installation groove 131 reserved in the lower cover 130 of the door body, and then the upper cover 110 of the door body is fastened, and the magnet 190 is pressed tightly by the positioning rib 111 on the upper cover 110 of the door body.

[0098] Combination Figure 15 , Figure 6 , Figure 7 and Figure 8 The upper cover 110 of the door body has a first buckle 112 on its inner wall and a first buckle hole 132 on its outer wall. After the upper cover 110 and the lower cover 130 of the door body are fastened together, each first buckle 112 is pre-fastened and positioned with each first buckle hole 132. Then, the upper cover 110 and the lower cover 130 of the door body are locked and fixed by thirteen screws 140.

[0099] Combination Figure 8 , Figures 15-18 The door seal 150 is installed in the second mounting groove 133 reserved in the lower cover 130 of the door body. A second buckle 134 is provided on one side wall of the second mounting groove 133, and a second buckle hole 135 is provided on the other side wall of the second mounting groove 133. The outer protrusion 151 of the door seal 150 engages with the second buckle 134, and the third buckle 152 on the inner wall of the door seal 150 engages with the second buckle hole 135 reserved in the lower cover 130 of the door body, thereby fixing the door seal 150. In this way, the main structure of the door seal 150 is fixed to the door assembly 100.

[0100] like Figure 9 and Figure 10The lock hook 180 is installed in the third mounting groove 136 reserved in the lower cover of the door body 130 and is fastened to the lower cover of the door body 130 by two lock hook screws 170. After that, the lock hook decorative piece 160 is pasted to cover the two lock hook screws 170 to achieve an aesthetic effect.

[0101] like Figure 20 For the door cover 110, a pivot seat is also provided on it. The pivot seat is provided with a pivot hole 114 through which the pivot 206 connecting the door assembly 100 and the box frame assembly 200 passes. A slot 115 is also provided in the radial direction of the pivot seat, and the slot 115 and the pivot hole 114 are connected.

[0102] like Figures 21-28 The box frame assembly 200 includes:

[0103] Box frame body 201, wherein an opening is provided on the box frame body 201;

[0104] A heating wire assembly 216 is arranged around the opening of the box frame body 201;

[0105] Hall component 213, which is assembled in a reserved slot on the box frame body 201, is used to sense the position of the magnet 190;

[0106] A rotating shaft fixing seat is fixed on the box frame body 201;

[0107] The damping shaft 205 is assembled in the shaft fixing seat;

[0108] The rotating shaft 206 has its end fitted into the damping rotating shaft 205;

[0109] The door cover 110 is rotatably connected to the pivot 206;

[0110] Torsion spring 207, one end of which is connected to the upper cover 110 of the door body, and the other end of which is connected to the box frame body 201.

[0111] like Figure 21 The heating wire assembly 216 is arranged in a pre-reserved groove around the opening of the frame body 201, and is locally fixed with hot melt adhesive after assembly to prevent it from falling off. When the refrigerator is cooling, the heating wire assembly 216 is activated by program control to prevent the door seal 150 of the vehicle refrigerator from leaking cold and forming a ring of condensation at the refrigerator opening.

[0112] like Figure 21The Hall effect sensor 213 is pre-installed into the pre-drilled groove at the front end of the frame body 201; then the Hall effect sensor cover 214 is placed on top and secured with two Hall effect screws 215. The Hall effect sensor 213 is used to sense the position of the magnet 190 in the door assembly 100, thereby determining the open or closed state of the refrigerator door.

[0113] like Figure 21 and Figure 24 After the latch 212 is inserted into the front hole 2011 of the box frame body 201, the latch plate 211 is then placed on top and secured with two latch screws 210. The latch trim 209 is attached to the latch plate 211 to cover the two latch screws 210.

[0114] like Figure 22 and Figure 23 In this embodiment, the rotating shaft fixing seat includes a left rotating shaft fixing seat 202 and a right rotating shaft fixing seat 203. The left rotating shaft fixing seat 202 and the right rotating shaft fixing seat 203 are fixed to the box frame body 201 by injection molding inserts.

[0115] like Figure 25 The outer rings of the two damping shafts 205 are respectively fixed in the circular holes of the left shaft fixing seat 202 and the right shaft fixing seat 203. The two damping shafts 205 provide a certain damping for the rotation of the shaft 206. The relationship between the left shaft fixing seat 202, the right shaft fixing seat 203, the damping shafts 205, and the anti-collision block 204 on the box frame body 201 is as follows: Figure 25 As shown.

[0116] To limit the maximum opening angle of the door cover 110, the frame assembly 200 also includes a bumper block 204. The bumper block 204 is inserted into a reserved groove in the frame body 201 and is interference-fitted with it to reduce the impact of the door cover 110 on the frame assembly 200 when it is opened. In this embodiment, the bumper block 204 is made of a material such as rubber.

[0117] Combination Figure 21 , Figure 25When assembling the door assembly 100 and the frame assembly 200, the middle part 2071 of the torsion spring 207 is inserted into the fourth mounting groove 2012 reserved in the frame body 201, and the two ends 2072 of the torsion spring 207 are inserted into the fifth mounting groove 113 reserved at the rear of the door assembly 100. The door assembly 100 is rotated to apply an initial torque to the torsion spring 207. Then, the slot 115 on the door assembly 100 is aligned with the two ribs 2051 on the inner shaft of the damping shaft 205 and inserted. The shaft 206 is then inserted from one side, passing through the left shaft fixing seat 202, the damping shaft 205, the shaft hole 114 of the door assembly 100, and the torsion spring 207, thus connecting the door assembly 100 and the frame assembly 200. Two retaining springs 208 are respectively engaged with the slots on the shaft 206 to prevent the shaft 206 from falling off.

[0118] Combination Figure 27 and Figure 28 With the refrigerator's flip-top door closed, pressing the finger icon on the door cover 110 causes the door assembly 100 to rotate around the pivot 206. The locking hook 180 on the door assembly 100 moves downwards, unlocking the latch 212 on the frame assembly 200. The door assembly 100 then automatically pops open under the torque of the torsion spring 207. During the opening process, the door assembly 100 rotates around the pivot 206, simultaneously rotating the inner shafts of the two damping pivots 205. Under the combined action of the torque of the damping pivots 205 and the torsion spring 207, the door assembly 100 opens smoothly and gently. When the door cover 110 reaches its maximum travel, it is stopped by the anti-collision rubber 204, effectively preventing impact during opening. When the refrigerator door is open, push the door assembly 100 back to the closed position and press the door assembly 100 again. The locking hook 180 on the door assembly 100 will insert into the latch 212 to complete the self-locking, and the door assembly 100 will be locked to the refrigerator frame assembly 200.

[0119] The detailed principles of the damping shaft 205, the press-locking buckle 212, and the locking hook 180 in this embodiment are mature and commonly used in the industry, and will not be explained in detail here.

[0120] In order to achieve a tactile feedback when opening and closing the door, the vehicle refrigerator in the above embodiments of this application has two force feedback elastic structures 153 designed on the door seal 150. When the door opening and closing action is generated, the opening of the frame body 201 on the frame assembly 200 will press the two force feedback elastic structures 153 on the door seal 150. Through the pressing deformation of these two force feedback elastic structures 153, combined with the torque of the torsion spring 207, the force of the latch 212, and the circumferential deformation feedback force of the door seal 150, the final pressing feedback output is as follows: Figure 3 The operating force curve was optimized, thereby improving the feel of opening and closing the door.

[0121] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited to this. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
