Description

Technical Field

[0001] This utility model relates to the field of shock absorption for vehicle refrigerators, and in particular to a quick-installation, shockproof, fully sealed, semi-automatic drawer-type vehicle refrigerator. Background Technology

[0002] In the field of car refrigerators, traditional drawer-type refrigerators have many shortcomings in terms of ease of installation, structural stability, and user experience. First, the installation process of existing products is complex, often requiring tools and multiple steps for assembly, making it difficult to achieve quick and secure installation and failing to meet users' needs for convenient installation. Second, due to manufacturing process limitations, components such as guide rails and inner liners have thickness and dimensional errors. During assembly, these errors can easily lead to loose fits between components, causing drawer wobbling and affecting stability and safety. In addition, the limiting structure design of traditional products is unreasonable, failing to effectively constrain the drawer's displacement in the X, Y, and Z directions, further exacerbating the wobbling problem. Regarding operating noise and energy consumption, the contact method between the push rod and the cabinet in traditional refrigerators is unreasonable, easily generating friction noise during operation. At the same time, the poor sealing performance of the push rod structure leads to serious cold air leakage, resulting in decreased cooling efficiency and increased energy consumption. Utility Model Content

Utilizing the quick-release structure and elastic mounting clips, the drawer and cabinet can be quickly fixed by simply pushing gently in the X direction, without the need for additional tools. This greatly improves installation efficiency, reduces installation difficulty, and meets users' needs for convenient installation.

[0011] 2. By placing elastic pads on the locking screws and designing the guide rail assembly as a trapezoidal structure, the error is converted into the tilt direction, effectively absorbing the manufacturing error of the guide rail thickness, ensuring a tight fit between components, and improving assembly accuracy and reliability.

[0012] 3. Through the synergistic effect of the slide rail limiting structure, the sliding limiting structure and the silent contact structure, the slide rail base connects the box frame, the inner liner base and the drawer into a stable whole, achieving zero-gap fixation in the X, Y and Z directions. This effectively avoids the shaking problem caused by insufficient manufacturing precision of the inner liner, guide rail and other components, ensuring stability and safety in use.

[0013] 4.

[0031] like Figure 2 , Figure 7 , Figure 10 As shown, the guide rail assembly 8 has a trapezoidal structure, which makes the error of the guide rail assembly 8 change to the tilt direction. The drawer pocket 6 is provided with a quick-connect structure 801 at the connection between it and the guide rail assembly 8. The guide rail assembly 8 is provided with a locking screw 802 corresponding to the quick-connect structure 801. An elastic soft pad 803 is sleeved on the locking screw 802.

[0032] like Figure 4 , Figure 10 , Figure 13 , Figure 14As shown, the slide rail limiting structure 9 includes elastic mounting buckles 901 and mounting holes 902. A pair of elastic mounting buckles 901 are provided at one end of the guide rail assembly 8 near the inner liner base 3, and a pair of mounting holes 902 are provided on the inner liner base 3. The elastic mounting buckles 901 and the mounting holes 902 are elastically engaged. A spring lock buckle 903 is provided at one end of the guide rail assembly 8 near the elastic mounting buckles 901. An anti-sway positioning block 904 is provided at the bottom of the drawer pocket 6. The anti-sway positioning block 904 is engaged with the spring lock buckle 903.

[0033] like Figure 11 , Figure 12 As shown, the sliding limiting structure 10 includes sliding feature blocks 1001. A pair of sliding feature blocks 1001 are disposed on the box frame 4. A pair of sliding grooves 1002 are provided below the guide rail assembly 8. The sliding feature blocks 1001 are slidably disposed in the sliding grooves 1002. A buffer bolt 1003 is provided at one end of the sliding groove 1002. A positioning hole 1004 is provided on the sliding feature block 1001. The positioning hole 1004 cooperates with the buffer bolt 1003. A limiting groove 1005 is provided at one end of the guide rail assembly 8 near the buffer bolt 1003. A limiting block 1006 is disposed below the drawer pocket 6. The limiting block 1006 cooperates with the limiting groove 1005. A gapless contact point 1007 is provided on the drawer pocket 6. The gapless contact point 1007 is in close contact with the box frame 4.

[0034] like Figure 4 , Figure 10 , Figure 14 As shown, the silent contact structure 11 includes a push rod 1101, which is located on the guide rail assembly 8 at one end near the inner liner base 3. The inner liner base 3 has a positioning groove 1102, which cooperates with the positioning groove 1102. A soft rubber sealing gasket 1103 is provided on the push rod 1101, and a soft rubber pin 1104 is provided below the guide rail assembly 8. The soft rubber pin 1104 is buffered and cooperates with the lower part of the spring lock 903.

[0035] In practice, the first step is to assemble the guide rail assembly 8 and the drawer 6. The guide rail assembly 8 is placed in a trapezoidal shape, utilizing its trapezoidal cross-section to convert potential manufacturing errors into a tilted direction. A quick-connect structure 801 is installed at the connection between the drawer 6 and the guide rail assembly 8. Simultaneously, locking screws 802 are screwed into the corresponding positions on the guide rail assembly 8, and elastic pads 803 are fitted onto the locking screws 802. Using tooling, the drawer 6 and the base of the guide rail assembly 8 are locked together with a constant design gap. The elastic pads 803 absorb manufacturing errors in the guide rail thickness, completing the elastic connection between the two.

[0036] Next, install the slide rail limiting structure 9. Install a pair of elastic mounting buckles 901 at the end of the guide rail assembly 8 near the inner liner base 3. Make corresponding mounting holes 902 on the inner liner base 3 to ensure that the elastic mounting buckles 901 and mounting holes 902 can elastically engage. Install a spring lock 903 on the end of the guide rail assembly 8 near the elastic mounting buckles 901. Install an anti-wobbling positioning block 904 at the bottom of the drawer pocket 6 to ensure that the anti-wobbling positioning block 904 and spring lock 903 can engage.

[0037] Then, install the sliding limit structure 10. Install a pair of sliding feature blocks 1001 on the frame 4, and open a pair of sliding grooves 1002 below the guide rail assembly 8, sliding the sliding feature blocks 1001 within the sliding grooves 1002. Screw in a buffer bolt 1003 at one end of the sliding groove 1002, and open a positioning hole 1004 on the sliding feature block 1001, so that the positioning hole 1004 mates with the buffer bolt 1003. Open a limit groove 1005 on the guide rail assembly 8 near the buffer bolt 1003, and install a limit block 1006 below the drawer pocket 6, ensuring that the limit block 1006 mates with the limit groove 1005. The gapless contact point 1007 on the drawer pocket is the point of positioning contact between the drawer pocket and the frame. Here, the edge dimension of the drawer pocket 6 is slightly larger than the dimensions of other parts of the drawer pocket, thus achieving a tight fit with the frame 4.

[0038] Finally, install the silent contact structure 11. Install a push rod 1101 on the guide rail assembly 8 near the inner liner base 3. Create a positioning groove 1102 on the corresponding position on the inner liner base 3. Attach a soft rubber sealing gasket 1103 to the push rod 1101. Install a soft rubber pin 1104 below the guide rail assembly 8 to ensure a buffered engagement between the soft rubber pin 1104 and the spring lock 903. Simultaneously, install the blown evaporator 7 on the outside of the drawer pocket 6, completing the assembly of the main components.
