Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, specifically to a vehicle refrigerator door structure that is easy to disassemble and assemble. Background Technology

[0002] Currently, most vehicle refrigerator doors use a symmetrical hinge structure. In actual use, after the vehicle refrigerator door is opened, it often falls quickly due to its own weight, resulting in noticeable impact noise and affecting the user experience. At the same time, because the hinges are symmetrically arranged on the left and right sides, when cleaning or repairing the door, it is often necessary to disassemble the connecting mechanisms on both sides simultaneously, which is cumbersome and time-consuming. Utility Model Content

[0003] The purpose of this utility model is to provide a vehicle refrigerator door structure that enables the vehicle refrigerator door to close slowly while facilitating disassembly and assembly.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vehicle refrigerator door structure that is easy to disassemble and assemble, including a cabinet, the cabinet having a receiving cavity and a placement opening communicating with the receiving cavity, a door that can cover the placement opening connected to the upper part of the cabinet, a damper that extends outwardly fixedly connected to one side of the door, a damping bushing correspondingly provided on the cabinet for the damper to be inserted to achieve pivot connection, a rotating shaft that can move along its axial direction on the other side of the door, a rotating shaft bushing correspondingly provided on the cabinet to cooperate with the end of the rotating shaft, a limiting member detachably connected to the door, the limiting member abutting against the rotating shaft to restrict the rotating shaft and keep its end inserted into the rotating shaft bushing, and an assembly gap between the door and the cabinet that allows the door to move after the rotating shaft is disengaged from the rotating shaft bushing, thereby allowing the damper to disengage from the damping bushing.

[0005] As a further optimization of this utility model, the door body includes an outer cover and an inner shell assembled inside the outer cover. The outer cover is provided with a first support seat for limiting the position of the limiting member and a first buckle for detachably fixing the bracket to the first support seat.

[0006] As a further optimization of this utility model, the inner shell is provided with a first pressing part that can press the limiting member after the outer cover and the inner shell are assembled, thereby preventing the limiting member from disengaging from the first support seat.

[0007] As a further optimization of this utility model, one end of the damper is connected to a mounting bracket, the outer cover is provided with a second support seat for limiting the position of the mounting bracket, and a second buckle for detachably fixing the second mounting bracket to the second support seat. The inner shell is provided with a second pressing part that can press the mounting bracket after the outer cover and the inner shell are assembled, thereby limiting the mounting bracket from detaching from the second support seat.

[0008] As a further optimization of this utility model, the limiting member is a limiting rod arranged in the front-back direction, and the limiting member has a top pressing boss on the side wall near the rotating shaft.

[0009] As a further optimization of this utility model, the front end of the inner shell is provided with a first receiving groove, the first receiving groove is provided with a first magnetic attracting member, the top of the front end of the box is provided with a forward-extending mounting flange, the lower part of the mounting flange is provided with a second receiving groove corresponding to the position of the first receiving groove, and the second receiving groove is provided with a second magnetic attracting member that attracts the first magnetic attracting member.

[0010] As a further optimization of this utility model, the number of the first magnetic components is two, and the two first magnetic components are symmetrically arranged on the inner shell.

[0011] As a further optimization of this utility model, the lower part of the front end of the inner shell is provided with an elastic buffer pin. The lower end of the buffer pin protrudes downward from the bottom surface of the inner shell and can abut against the box when the door rotates at a preset angle relative to the box.

[0012] As a further optimization of this utility model, the door body is provided with a handle, and a positioning pin for pre-positioning and a screw for fixing the two together are provided between the handle and the door body.

[0013] As a further optimization of this utility model, the number of positioning pins is at least two, the number of screws is at least three, and the screws and positioning pins are arranged alternately along the length of the handle.

[0014] Compared with the prior art, this utility model has the following advantages: By setting a damper on one side of the door and cooperating with the damping bushing on the housing to form a damped pivot structure, it can provide a smooth buffer resistance when the door falls under the action of gravity, avoid impacting the housing and generating obvious noise, and improve the user experience. At the same time, a pivot that can move axially is set on the other side of the door and cooperates with the limiting component. When disassembling the door, it is only necessary to remove the limiting component and pull the pivot out of the pivot bushing. Then, by using the reserved assembly gap to move the door laterally, the damper can be disengaged from the damping bushing, which improves the convenience of disassembly and assembly and facilitates daily cleaning, fault repair or component replacement.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 7 As shown, this utility model discloses a vehicle refrigerator door structure that is easy to disassemble and assemble, including a cabinet 1. The cabinet 1 has a receiving cavity 11 and a placement opening 12 connected to the receiving cavity 11. A door 2 that can cover the placement opening 12 is connected to the upper part of the cabinet 1. A damper 31 that extends outward is fixedly connected to one side of the door 2. The cabinet 1 is correspondingly provided with a damping sleeve 32 for the damper 31 to be inserted to achieve pivot connection. The other side of the door 2 is provided with a rotating shaft 41 that can move along its axial direction. The cabinet 1 is correspondingly provided with a rotating shaft sleeve 42 that cooperates with the end of the rotating shaft 41. A limiting member 5 is detachably connected to the door 2. The limiting member 5 abuts against the rotating shaft 41 to limit the rotating shaft 41 and keep its end inserted into the rotating shaft sleeve 42. An assembly gap 6 is provided between the door 2 and the cabinet 1 to allow the door 2 to move after the rotating shaft 41 is disengaged from the rotating shaft sleeve 42, thereby allowing the damper 31 to disengage from the damping sleeve 32.

[0024] In this embodiment, the cabinet 1 has an internal cavity 11 for storing refrigerated items, and an opening 12 communicating with the cavity 11 is provided at the top of the cabinet 1 for users to place and retrieve items. The door 2 is sized to match the opening 12 and is used to cover the opening 12 when closed, achieving heat preservation and sealing. A damper 31 is fixedly connected to one side of the door 2. The damper 31 generates a resistance torque during rotation. Its specific structure is existing technology, such as the damping core in common furniture soft-close hinges, which can be directly purchased or integrated into the design, so it will not be described in detail here. A damping bushing 32 is provided at a corresponding position on the cabinet 1. The damping bushing 32 allows the damper 31 to be inserted into it and rotate around its axis, thereby forming a rotating fulcrum with a buffer function. When the door 2 is opened and falls due to gravity, the damper 31 provides a continuous damping force, slowing down the closing speed and avoiding impact noise. A pivot 41 is provided on the other side of the door 2. The pivot 41 can be slidably installed in the shaft hole or groove of the door body 2 along its own axis. The housing 1 has a pivot sleeve 42 at a corresponding position. By inserting the end of the pivot 41 into the pivot sleeve 42, it forms two rotational fulcrums of the door body 2 together with the damper 31, ensuring stable opening and closing of the door. The limiting member 5 can be in the form of screws, clips, elastic retaining rings, or sliding lock blocks, and is detachably connected to the door body 2. When the limiting member 5 is installed in place, its inner surface or end face abuts against the outer end face of the pivot 41, thereby restricting the pivot 41 from moving in the disengagement direction and ensuring that its end remains within the pivot sleeve 42. An assembly gap 6 is reserved between the door body 2 and the housing 1. After the user removes the limiting piece 5, the rotating shaft 41 can be manually pulled out axially so that its end is separated from the rotating shaft sleeve 42. Then, the door body 2 is moved laterally a distance to the rotating shaft side so that the damper 31 inserted in the damping sleeve 32 can get space to disengage and be pulled out from the damping sleeve 32, thus achieving quick disassembly.

[0025] By setting a damper 31 on one side of the door body 2 and cooperating with the damping bushing 32 on the housing 1 to form a damped pivot structure, a smooth buffer resistance can be provided when the door body 2 falls under the action of gravity, avoiding impact with the housing 1 and generating obvious noise, thus improving the user experience. On the other side of the door body 2, an axially movable pivot 41 is set with a limiting member 5. When disassembling the door body, it is only necessary to remove the limiting member 5 and pull the pivot 31 out of the pivot bushing 32. Then, by using the reserved assembly gap 6 to move the door body 2 laterally, the damper 31 can be disengaged from the damping bushing 32, which improves the convenience of disassembly and assembly and facilitates daily cleaning, fault diagnosis or component replacement.

[0026] The door body 2 includes an outer cover 21 and an inner shell 22 assembled inside the outer cover 21. The outer cover 21 is provided with a first support seat 211 for limiting the position of the limiting member 5 and a first buckle member 212 for detachably fixing the bracket to the first support seat 211.

[0027] In this embodiment, multiple first support bases 211 are provided and spaced apart along the length of the limiting member 5. The first support bases 211 are integrally formed and disposed inside the outer cover 21, with reinforcing ribs on their sidewalls to enhance structural rigidity and load-bearing capacity. Multiple first latching members 212 are provided and spaced apart along the length of the limiting member 5, thereby fixing the limiting member 5 to the first support bases 211 through a multi-point support and multi-point latching mechanism. This ensures that the limiting member 5 is evenly stressed and securely installed across the entire contact surface, allowing it to reliably abut against the rotating shaft 41 to prevent it from dislodging. When the door body 2 needs to be disassembled, the user can manually release the latches and remove the limiting member 5, a simple operation that meets the needs of rapid maintenance in a vehicle environment. The combination of the first support bases 211 and the first latching members 212 enhances the fixing strength of the limiting member 5, preventing it from loosening or deforming during use and improving the durability of the door body 2.

[0028] The inner shell 22 is provided with a first pressing part 221 that can press the limiting member 5 after the outer cover 21 and the inner shell 22 are assembled, thereby preventing the limiting member 5 from disengaging from the first support seat 211.

[0029] In this embodiment, the first pressing part 221 is a protruding structure extending from the inner shell 22 towards the outer cover 21 from the position corresponding to the limiting member 5. When the outer cover 21 and the inner shell 22 are assembled by means of buckles, screws, etc., the first pressing part 221 is located at the lower part of the limiting member 5 and presses against the lower surface of the limiting member 5. Even if the first buckle member 212 becomes slightly loose due to vibration or aging, the first pressing part 221 can provide physical blocking to prevent the limiting member 5 from detaching from the first support seat 211.

[0030] One end of the damper 31 is connected to the mounting bracket 7. The outer cover 21 is provided with a second support 213 for limiting the position of the mounting bracket 7 and a second buckle 214 for detachably fixing the second mounting bracket 7 to the second support 213. The inner shell 22 is provided with a second pressing part 222 that can press the mounting bracket 7 after the outer cover 21 and the inner shell 22 are assembled, thereby limiting the mounting bracket 7 from detaching from the second support 213.

[0031] One end of the damper 31 is connected to a mounting bracket 7, which secures the damper 31 to the door body 2. A second support seat 213 is provided on the inner side of the outer cover 21. This second support seat 213 does not support the mounting bracket 7 from below, but rather restricts the vertical or horizontal displacement of the mounting bracket 7. Simultaneously, the outer cover 21 also has a reverse arm as a second latching element 214, which cooperates with the second support seat 213 to detachably fix the mounting bracket 7 in a predetermined installation position. After the outer cover 21 and inner shell 22 are assembled, the boss of the second pressing part 222 on the inner shell 22 presses against the mounting bracket 7, forming a multi-directional limiting structure together with the second support seat 213 and the second latching element 214 on the outer cover side, preventing the mounting bracket 7 from loosening or falling off.

[0032] The limiting member 5 is a limiting rod arranged in the front-to-back direction, and the limiting member 5 has a pressing boss 51 on its side wall near the rotating shaft 41. The setting of the pressing boss 51 can avoid assembly interference caused by large-area contact of the limiting member 5, and the pressing boss 51 provides a clear limiting point, which concentrates the force, is not easy to deform, and ensures that it will not fail in long-term use.

[0033] The inner shell 22 has a first receiving groove 223 at its front end, and a first magnetic attractor 81 is provided in the first receiving groove 223. The top of the front end of the box body 1 has a forward-extending mounting flange 13. The lower part of the mounting flange 13 is provided with a second receiving groove 131 corresponding to the position of the first receiving groove 223. The second receiving groove 131 has a second magnetic attractor 82 that attracts the first magnetic attractor 81.

[0034] The inner shell 22 has a first receiving groove 223 at its front end for embedding a permanent magnet or ferrite magnetic block as a first magnetic attractor 81. Correspondingly, a forward-extending mounting flange 13 is provided at the top of the front end of the housing 1. The mounting flange 13 enhances the rigidity of the housing and provides a mounting reference for magnetic attraction. A second receiving groove 131 is provided at the lower part of the mounting flange 13, directly opposite the first receiving groove 223. Its shape matches the first receiving groove 223 and is used to embed a second magnetic attractor 82. When the door 2 is closed, the first magnetic attractor 81 and the second magnetic attractor 82 align with each other and generate magnetic attraction, thereby attracting the door 2 to the housing 1, guiding the door 2 to close, and ensuring the stability and sealing of the door 2 after it is closed.

[0035] There are two first magnetic suction components 81, and the two first magnetic suction components 81 are symmetrically arranged on the inner shell 22 to ensure that the door 2 is subjected to uniform force when closed, and to avoid the door 2 being tilted, not sealed properly, or stuck when opened due to unilateral adsorption.

[0036] The lower part of the front end of the inner shell 22 is provided with an elastic buffer pin 83. The lower end of the buffer pin 83 protrudes downward from the bottom surface of the inner shell 22 and can abut against the box 1 when the door 2 rotates at a preset angle relative to the box 1.

[0037] The buffer pin 83 is made of an elastic material such as silicone, thermoplastic elastomer, or soft rubber, possessing good compression and rebound properties. The lower end of the buffer pin 83 protrudes downwards from the bottom surface of the inner shell 22. When the door 2 rotates downwards to a preset angle around its hinge axis via the damper 31 and the pivot 41, the lower end of the buffer pin 83 will first contact the upper surface of the housing 1 or the corresponding support part and undergo elastic compression, thereby buffering the impact of the door 2 falling and preventing noise from hard collisions. In this embodiment, the lower part of the buffer pin 83 is provided with multiple spherical protrusions 831 to improve wear resistance and service life.

[0038] The door body 2 is provided with a handle 91, and a positioning pin 92 for pre-positioning and a screw 93 for fixing the two together are provided between the handle 91 and the door body 2.

[0039] A positioning pin 92 is provided on one of the door body 2 and the handle 91; the corresponding other component has a positioning hole that matches the positioning pin 92. The positioning pin 92 achieves pre-positioning between the handle 91 and the door body 2, preventing misalignment or stress concentration when the screw 93 is tightened. After pre-positioning, at least one screw 93 is passed through the through hole on the handle 91 and screwed into the corresponding threaded hole on the door body 2, such as the outer cover 21, to securely connect the two. The screw 93 primarily bears the tensile and shear forces borne by the handle 91 during use, ensuring it remains secure even after long-term use.

[0040] The number of positioning pins 92 is at least two, and the number of screws 93 is at least three. The screws 93 and positioning pins 92 are arranged alternately along the length of the handle 91, thereby ensuring uniform positioning and fixing along the length of the handle 91. The alternating arrangement at multiple points avoids local stress concentration and improves structural strength.
