Description

Technical Field

[0001] This application relates to the field of vehicle refrigerators, and more particularly to a drawer quick-release structure. Background Technology

[0002] As the global automotive industry undergoes a profound transformation towards electrification, intelligentization, and connectivity, the role of the car is evolving from a traditional "means of transportation" to a new "mobile living space." Users' demands for cars are no longer limited to basic transportation; they extend to diverse scenarios such as leisure and entertainment, mobile office work, and outdoor camping. Under this trend, in-car refrigerators, which can ensure the preservation of food and beverages and improve the quality and convenience of travel, have gradually transformed from a high-end optional extra or outdoor-specific equipment into an important in-car device that meets users' "scenario-based essential needs."

[0003] Existing drawer locking mechanisms typically include an adapter fixed to the refrigerator body, a drive assembly for rotating the adapter, and a latch fixed to the drawer slide rail. One end of the latch engages with the drawer frame, one end of the adapter is fixedly connected to the drive assembly, and the other end of the latch is coaxially connected to the other end of the adapter. When the drawer needs to be removed entirely for maintenance or replacement, the drive assembly activates the adapter, causing the latch to rotate and unlock, allowing the drawer to be removed. After the drawer is pulled out, the latch resets under the action of a reset mechanism (such as a torsion spring). However, at this time, the adapter has rotated at a certain angle and deviated from its initial mating position. Therefore, when reinstalling the drawer, it is difficult to accurately align the adapter with the latch because the adapter has been deflected, making it difficult to install the drawer smoothly. To solve this problem, the current method is usually to remove the entire vehicle refrigerator from the vehicle and manually pull the adapter back from the rear of the refrigerator to rotate it back to the mating angle. However, this method is time-consuming, labor-intensive, and very inconvenient. Utility Model Content

[0004] To address the problems of difficulty in disassembling and reassembling existing drawer locking structures in vehicle refrigerators, as well as poor maintenance convenience, this application provides a quick-release drawer structure.

[0005] The drawer quick-release structure provided in this application adopts the following technical solution: A quick-release drawer structure includes an adapter and a latch, one end of which is axially engaged with one end of the adapter. The drawer also includes a push rod and a reset element disposed on the push rod. One end of the push rod is coaxially and fixedly connected to the end of the adapter opposite to the latch. The reset element acts between the push rod and the drawer body to provide a reset force to the push rod towards its initial position.

[0006] By adopting the above technical solution, one end of the push rod is coaxially fixedly connected to the adapter. The reset component acts between the push rod and the cabinet. When external driving force drives the push rod to rotate the adapter and unlock the drawer, the reset component automatically drives the adapter and push rod to rotate in opposite directions under the reset force, returning them to their initial docking position. This ensures that the latch aligns with the adapter when the drawer is installed. Compared to existing technologies, when the drawer is disassembled and reinstalled, the adapter automatically resets, and the latch accurately aligns with the adapter, improving the convenience and reliability of disassembly and assembly.

[0007] Preferably, the push rod includes an abutment portion and an insertion portion, one end of the insertion portion is coaxially and fixedly connected to the adapter, the other end of the insertion portion extends radially outward to form the abutment portion, and one end of the reset member acts on the abutment portion.

[0008] Preferably, the reset component is a torsion spring, which is sleeved outside the insertion part, with one end of the torsion spring connected to the abutment part and the other end of the torsion spring connected to the housing.

[0009] Preferably, the plug-in portion is fitted with an mounting member, the mounting member is fixed relative to the housing, and the torsion spring is sleeved on the mounting member.

[0010] Preferably, it also includes a driving component, a fixed base is fixed on the housing, the driving component is fixed on the fixed base, and the end of the torsion spring opposite to the abutment portion is hooked on the fixed base.

[0011] Preferably, a fastening bolt is provided between the adapter and the push rod, and the fastening bolt passes axially through the adapter and the push rod to fix the adapter and the push rod together.

[0012] Preferably, the latch includes a connecting portion and a locking portion formed by radially extending the outer periphery of the connecting portion. The connecting portion engages with the adapter. The locking portion has a locking tongue at the end away from the connecting portion. The locking tongue is provided with a locking bevel, which is inclined upward along the installation direction of the frame.

[0013] Preferably, the connecting part is provided with a return spring along the axial direction for the latch to reset, the connecting part is provided with a mounting cavity on the side opposite to the adapter, the return spring is installed in the mounting cavity, one end of the return spring extends out of the mounting cavity to connect with the slide rail, the locking part is provided with a receiving cavity communicating with the mounting cavity, and the other end of the return spring is fixed in the receiving cavity.

[0014] In summary, this application includes at least one of the following beneficial technical effects: Easy to install, saving time and manpower, the adapter can be accurately reset to the docking angle without any manual intervention through the reset component, and users or maintenance personnel can quickly complete the reinstallation of the drawers without disassembling the entire vehicle refrigerator; It has good applicability and is easy to implement, requiring no modification to the existing structure of the latch and adapter; The product is highly durable, avoiding damage to components such as the motor and push rod that may be caused by frequent disassembly of the refrigerator or rough manual reset, thus reducing the failure rate and extending the product's service life.

[0024] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0025] This application discloses a quick-release drawer structure. (Refer to...) Figure 1 and Figure 2 The vehicle-mounted refrigerator includes a cabinet 1 and a drawer assembly 2. The drawer assembly 2 includes a slide rail 21 fixed inside the cabinet 1 and a frame 22 mounted on the slide rail 21. The frame 22 is used to store items and is slidably installed inside the cabinet 1 via the slide rail 21. (See reference...) Figure 1 The quick-release drawer assembly includes a drive unit 3, a push rod 4, an adapter 5, and a latch 6. The drive unit 3 drives the push rod 4 to rotate. One end of the push rod 4 is coaxially fixedly connected to one end of the adapter 5. The other end of the adapter 5 engages with one end of the latch 6, and the other end of the latch 6 is locked to the frame 22. When the latch 6 is locked, the frame 22 is closed. A reset element 7 is provided on the push rod 4, acting between the push rod 4 and the housing 1 to provide a reset force for the push rod 4 to reset after rotation. When disassembling the drawer assembly 2, the drive unit 3 drives the push rod 4 to rotate and unlock the latch 6. After the drawer assembly 2 is disassembled, the latch 6 resets. Simultaneously, under the action of the reset element 7, the push rod 4 drives the adapter 5 to rotate in the opposite direction and reset. When installing the drawer assembly 2, the frame 22 is locked to one end of the latch 6, and the other end of the latch 6 is aligned with and axially engages with the end of the adapter 5 opposite to the push rod 4, thus achieving quick installation of the drawer assembly 2.

[0026] Reference Figure 3 and Figure 4 The push rod 4 includes an abutment portion 41 and a plug portion 42. One end of the plug portion 42 is coaxially and fixedly connected to the adapter 5, and the other end of the plug portion 42 extends radially outward to form the abutment portion 41. The driving member 3 abuts against the abutment portion 41, and the driving member 3 drives the plug portion 42 to rotate by driving the abutment portion 41. The reset member 7 is provided outside the plug portion 42. One end of the reset member 7 acts on the abutment portion 41, and the other end of the reset member 7 acts on the housing 1. The abutment portion 41 and the plug portion 42 are preferably integrally formed. Optionally, the abutment portion 41 can also be fixedly connected by fasteners such as bolts or screws.

[0027] A fastening bolt 43 is also provided between the push rod 4 and the adapter 5 to fix the two together. The fastening bolt 43 passes through the plug part 42 from one side of the adapter 5 to fix the push rod 4 and the adapter 5 together. Optionally, the fastening bolt 43 can also be replaced by other methods such as fastening screws or adhesive.

[0028] Reference Figure 5 and Figure 6In a preferred embodiment, the reset member 7 is a torsion spring 71, which is sleeved on the outside of the insertion part 42. One end of the torsion spring 71 is hooked onto the abutment part 41, and the other end is hooked onto the housing 1. When the driving member 3 drives the abutment part 41 to rotate, the torsion spring 71 deforms and stores elastic potential energy. When the driving member 3 disengages from the abutment part 41, the abutment part 41 rotates back to its original position under the action of the torsion spring 71. Further, the insertion part 42 is sleeved with a mounting member 8, which is used to install the torsion spring 71. The mounting member 8 is fixed relative to the housing 1, and the torsion spring 71 is sleeved and fixed relative to the mounting member 8.

[0029] A foamed skeleton 9 is provided at the end of the frame 22, covering the end of the frame 22. The foamed skeleton 9 has a recessed groove 91 on its side away from the frame 22 for the push rod 4 and the adapter 5 to pass through. Preferably, the groove wall of the recessed groove 91 protrudes away from the frame 22 to form a surrounding portion 92, which can serve as a mounting part 8 for installing the torsion spring 71. The surrounding portion 92 surrounds the outer periphery of the adapter 5 and the insertion portion 42. The torsion spring 71 is sleeved on the outer periphery of the surrounding portion 92 and relatively fixed. The foamed material also protects the adapter 5 and the push rod 4, providing cushioning and stopping effects.

[0030] Reference Figure 1 and Figure 2 The housing 1 includes a shell 11, a drawer assembly 2 installed inside the shell 11, a fixing seat 111 on the outer wall of the shell 11, a drive member 3 fixed on the fixing seat 111, and a surrounding part 92 passing through the shell 11 from the inside, so that the abutting part 41 abuts against the drive member 3. One end of the torsion spring 71 is hooked on the abutting part 41, and the other end of the torsion spring 71 is hooked on the fixing seat 111.

[0031] Reference Figure 3 In one embodiment, the driving component 3 is preferably a solenoid valve, which has a push end 31 that abuts against the abutment portion 41. When the solenoid valve is activated, the push end 31 extends to abut against the abutment portion 41, causing the push rod 4 to rotate. When the solenoid valve is closed, the push end 31 retracts, and the abutment portion 41 rotates in the opposite direction under the action of the reset component 7, causing the push rod 4 to drive the adapter 5 to reset. Obviously, the driving component 3 can also be implemented by other means such as a cylinder.

[0032] Reference Figure 7The latch 6 includes a connecting part 61 and a locking part 62. The connecting part 61 is used to engage with the adapter 5. The locking part 62 is formed by radially extending from the outer periphery of the connecting part 61. The end of the locking part 62 away from the connecting part 61 has a latch 621. The latch 621 is provided with a snap-fit ​​slope 622. Taking the direction of the attached drawing as an example, the snap-fit ​​slope 622 is inclined upward along the installation direction of the frame 22. Correspondingly, the frame 22 is provided with a latch 221 that matches the latch 621. The latch 221 is also provided with a guide slope 222. When the frame 22 is axially pushed into the rear end of the slide rail 21, the guide slope 222 slides along the snap-fit ​​slope 622, causing the latch 221 to fall into the side of the latch 621 away from the snap-fit ​​slope 622, thereby restricting the axial retraction of the latch 221 by the latch 621. Under the action of axial force, the locking tongue 621 is difficult to disengage from the latch 221, but the locking part 62 can disengage from the latch 221 after rotating circumferentially by a certain angle.

[0033] Reference Figure 8 The latch 6 is also equipped with a return spring 63 for resetting the latch 6. When the locking part 62 rotates circumferentially, causing the latch tongue 621 to disengage from the latch 221 and the frame 22 to be pulled out, the latch 6 can be reset under the action of the return spring 63. The return spring 63 is preferably a torsion spring. Specifically, the connecting part 61 has a mounting cavity 611 on the side away from the adapter 5, and the locking part 62 has a receiving cavity 623 that communicates with the mounting cavity 611. The return spring 63 is installed in the mounting cavity 611, with one end of the return spring 63 extending out of the mounting cavity 611 and connected to the slide rail 21, and the other end of the return spring 63 relatively fixed in the receiving cavity 623. After the latch 6 rotates, one end of the return spring 63 abuts against the cavity wall of the receiving cavity 623, causing the latch 6 to reverse and reset.

[0034] The implementation principle of the quick-release drawer structure in this application embodiment is as follows: A torsion spring 71 is installed on the insertion part 42, acting between the fixed base 111 and the abutment part 41. The torsion spring 71 is sleeved and relatively fixed outside the mounting part 8. One end of the torsion spring 71 is hooked on the fixed base 111, and the other end of the torsion spring 71 is hooked on the abutment part 41. When disassembling the drawer assembly 2, the driving member 3 drives the abutment part 41 to rotate, causing the adapter 5 to rotate and unlock the latch 6. The rotation of the abutment part 41 causes the torsion spring 71 to store elastic potential energy. When the driving member 3 releases its grip on the abutment part 41, the torsion spring 71 releases its elastic potential energy, causing the push rod 4 to rotate in the opposite direction to drive the adapter 5 to reset. When installing the drawer assembly 2, the latch 6 can be directly aligned with the adapter 5 to achieve quick drawer installation.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
