Description

Technical Field

[0001] The utility model relates to the technical field of vehicle processing, in particular to a suspension-type refrigerator shock-absorbing mechanism for a camping vehicle. Background Art

[0002] A campervan air conditioner is a refrigeration unit installed on the outside of the campervan. It works in conjunction with the interior unit installed inside the vehicle to perform air conditioning. In a campervan, the air conditioner typically includes a compressor, a condenser, and other related components. These components compress the refrigerant and dissipate heat, thereby reducing the temperature inside the vehicle. Since the air conditioner is suspended in the campervan, a shock-absorbing component is needed to help mitigate the impact of gravity on the campervan from the air conditioner, improving the user experience. For example, Chinese patent publication number CN208885873U discloses a shock-absorbing device for a motorhome air conditioner outdoor unit. This device primarily utilizes lateral and longitudinal shock absorbers to dampen vibrations in both the lateral and longitudinal directions of the outdoor unit. The included shock-absorbing pads reduce vibrations from the outdoor unit's main body and floor to the vehicle body, resulting in low noise levels inside the vehicle. However, since the lateral shock absorber primarily serves to dampen the lateral vibration frequency of the outdoor unit, while the longitudinal shock absorber primarily serves to dampen longitudinal vibration frequency, the shock absorber is used to dampen the longitudinal vibration frequency. When the transverse shock absorber and the longitudinal shock absorber are connected to the outside of the air conditioner outdoor unit, the vibration frequencies generated in the transverse and longitudinal directions are prone to cross-vibration, resulting in a dry vibration buffering force, causing the air conditioner outdoor unit to induce resonance and reduce the shock absorption effect.

DETAILED DESCRIPTION

[0026] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0027] Example 1

[0028] See also Figures 1 to 3 The utility model provides a shock absorbing mechanism for a suspended refrigerator for a camping vehicle, comprising a support base 1, a plurality of symmetrical limit rods 2 provided on the top surface of the support base 1, two of which are connected to the outside of the camping vehicle through a first fastener 3, and a plurality of limit rods 2 are provided with a damping assembly and connected to the side of an air-conditioning assembly 4, and a damping assembly is provided between the air-conditioning assembly 4 and the side of the camping vehicle, a first fixing plate 5 is provided on the bottom surface of the support base 1, and the first fixing plate 5 is coaxially fixed to the outside of the camping vehicle with the first fastener 3 through a second fastener 6, and the first fixing plate 5 is connected to the support base 1 through a support rod, and the support base 1 includes a plurality of buffer springs 7 provided on the top surface, and the other end of the buffer spring 7 is connected to a fastening assembly, which is used to fasten the bottom of the air-conditioning assembly 4 to the support base 1.

[0029] It should be noted that the first fastener 3 and the second fastener 6 are composed of existing bolts and nuts. At least four limiting rods 2 are provided.

[0030] It is worth noting that the air conditioning assembly 4 includes, but is not limited to, a square air conditioning outdoor unit, a reassembled air conditioning outdoor unit with a smaller size, or an air conditioning outdoor unit with an oval outer shell. The air conditioning assembly 4 can have different shapes to meet practical applications. This embodiment uses a square air conditioning outdoor unit as an example.

[0031] In one example, the air conditioning assembly 4 is secured to the exterior of the camper van using the first fixing plate 5 and the limiting rod 2 of the support base 1 via the first and second fasteners 3 and 6. The support rod is provided via the first fixing plate 5 to enhance the stability of the air conditioning assembly 4. During transport of the camper van and operation of the air conditioner, bumps and vibrations generated are mitigated by multiple buffer springs 7 at the bottom of the air conditioning assembly 4. This prevents rigid contact between the air conditioning assembly 4 and the vehicle body, which could damage the connection and mounting structure of the air conditioning assembly 4. Furthermore, the strong clamping action of the fastening assembly secures the air conditioning assembly 4 against the top surfaces of the buffer springs 7, effectively buffering the impact of bumps and vibrations. Furthermore, the damping effect of the damping assembly limits the left and right swaying of the air conditioning assembly 4. The buffer springs 7 and the damping assembly work together to reduce resonance within the air conditioning assembly 4 and enhance shock absorption.

[0032] In this embodiment, if Figure 1 and Figure 3 As shown, the damping assembly includes a first damping hinge block 8, a second damping hinge block 9, a third damping hinge block 10, a first connecting rod 11 and a second connecting rod 12. The first damping hinge block 8 is provided on the side wall of the limit rod 2 and the side of the camper, and is connected to one end of the first connecting rod 11. The second damping hinge block 9 is provided on the side and rear of the air conditioning assembly 4 ( Figure 1 Not shown, Figure 3 The left side), one end of the second connecting rod 12 is connected to the second damping hinge block 9, and the other end of the first connecting rod 11 and the second connecting rod 12 are connected through the third damping hinge block 10.

[0033] It should be noted that the first damping hinge and the second damping hinge block 9 are ball-jointed universal damping hinges, and the third damping hinge block 10 is a wrapped damping shaft.

[0034] When the air conditioner assembly 4 sways back and forth, or left and right, the first connecting rod 11 and the second connecting rod 12 are shaken, allowing the first damping hinge block 8 and the second damping hinge to swing freely, generating damping friction to stabilize the assembly. This repeated swinging generates damping friction to stabilize the assembly again. This reciprocating motion prevents resonance between the back and forth, left and right swings of the air conditioner assembly 4 and the buffer spring 7. However, the third damping hinge is used to generate damping friction when the air conditioner assembly 4 swings left and right, further enhancing the overall damping effect.

[0035] Furthermore, threaded rods are welded to the sides of the air-conditioning assembly 4 and the limiting rod 2, and the first damping hinge block 8 and the second damping hinge block 9 are both provided with a pressure plate 13, and the pressure plate 13 is provided with a through hole corresponding to the threaded rod. The threaded rod passes through the through hole, and the pressure plate 13 is fixed to the air-conditioning assembly 4, the side of the camping vehicle and the side of the limiting rod 2 after being threadedly connected with a nut.

[0036] The first damping hinge block 8 and the second damping hinge block 9 are adapted to the air-conditioning assembly 4, the side of the camping vehicle and the side of the limit rod 2 by setting the pressure plate 13, thereby improving the stability of the support base 1 and the limit rod 2 and improving the shock absorption effect after defecation.

[0037] Example 2

[0038] See also Figures 1 to 2 As a further improvement of Example 1, the support base 1 is provided with an air storage box 14, the top surface of the air storage box 14 is connected to the bottom end of the buffer spring 7, and a compression rod 15 and a compression cylinder 16 are sleeved in the buffer spring 7. One end of the compression rod 15 is provided with a piston that slides up and down the inner wall of the compression cylinder 16, and the other end is connected to the bottom surface of the fastening assembly. The bottom end of the compression cylinder 16 is connected to the top surface of the air box; the top surface of the air storage box 14 is also connected to a first bellows 17 and a second bellows 18, which are connected to the air-conditioning assembly 4 through a bent pipe 19, and one end of the bent pipe 19 extends into the air-conditioning assembly 4.

[0039] When the air conditioning assembly 4 vibrates, the buffer spring 7 is compressed, causing the piston at the bottom end of the compression rod 15 to apply pressure to the compression cylinder 16, thereby generating air that is pre-stored in the air storage tank 14. The air in the air storage tank 14 then vibrates continuously through the air conditioning assembly 4 to generate new air. The gas stored in the air storage tank 14 flows through the first bellows 17 and the second bellows 18 and the bent pipe 19 into the air conditioning assembly 4, dissipating heat and removing dust from the components inside the air conditioning assembly 4.

[0040] Furthermore, an elastic ring 20 is provided on the outer circumference of the bending tube 19 to be detachably in close contact with the outer side of the air conditioner assembly 4. The elastic ring 20 is provided to prevent gas leakage and the inability to stably perform heat dissipation and dust removal. At the same time, the bellows can also be disassembled to complete the replacement.

[0041] Example 3

[0042] See also Figures 3 to 5 As a further improvement of Example 1, the fastening component includes a concave plate 21 and a movable plate 22. The movable plate 22 can be raised and lowered in the concave plate 21. A rotating clamp 23 is provided on the side of the concave plate 21. One end of the rotating clamp 23 is rotatably connected to the movable plate 22. The air-conditioning assembly 4 is provided with a slot 24. When the movable plate 22 sinks, the other end of the rotating clamp 23 is driven to engage with the slot 24. The rotating clamp 23 has a built-in spring 25 connected to the side of the concave plate 21.

[0043] In the initial state, the height of the movable plate 22 is higher than the top surface of the concave plate 21, and the spring 25 is in the initial state. When the air conditioner assembly 4 is placed on the top surface of the concave plate 21, pressure is applied to the movable plate 22, so that the movable plate 22 moves in front of and behind the concave plate 21 (such as Figure 5The inner wall (shown in the front and rear) slides downward, thereby driving the rotating clamp 23 to rotate the clockwork spring 25 to contract, and simultaneously rotating the upper end of the rotating clamp 23 toward the air conditioner assembly 4. When the air conditioner assembly 4 is stably placed, the upper end of the rotating clamp 23 engages with the retaining groove 24 of the air conditioner assembly 4, thereby preventing the air conditioner assembly 4 from deflecting during bumps and vibrations, which could affect its stability.

[0044] Preferably, a second fixing plate 26 is provided on the other side of the air-conditioning assembly 4, and the second fixing plate 26 is provided with a through hole. A screw rod 27 is threaded through the concave plate 21, and vertical rods 28 are provided on the left and right sides of the screw rod 27. The top ends of the vertical rods 28 at both ends are rotatably connected to a swinging plate 29, and one end of the swinging plate 29 is rotatably connected to the top end of the screw rod 27. The swinging plate 29 is used to fix the second fixing plate 26 on the movable plate 22.

[0045] After the rotating clamp 23 is adapted and engaged with the slot 24, the screw rod 27 is rotated to make the screw rod 27 move upward, and then the swinging piece 29 at the top of the two vertical rods 28 is opened and swung toward the top surface of the second fixed piece 26. When the swinging piece 29 is vertically attached to the top surface of the second fixed piece 26, the rotation of the screw rod 27 is stopped. At this time, the swinging piece 29, the second fixed piece 26 and the screw rod 27 limit the upward movement of the air-conditioning assembly 4, preventing the air-conditioning assembly 4 from detaching from the rotating clamp 23, affecting the stability of the rotating clamp 23 and the slot 24.

[0046] Furthermore, a rotating roller 30 is provided at the bottom end of the screw rod 27, which facilitates holding the rotating roller 30 to rotate the screw rod 27 to complete the lifting.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
