[0026] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] As Figures 1-6 shown, a drive bracket and a vehicle - mounted refrigerator with sealing and shock - absorbing functions are provided. The drive bracket with sealing and shock - absorbing functions includes a fixed bracket 1 and a transmission mechanism 2 installed on the fixed bracket 1. A sealing structure 3 and a shock - absorbing structure 4 for absorbing the vibration generated by the transmission mechanism 2 are provided on the fixed bracket 1.

[0028] Specifically, by providing the sealing structure 3 on the fixed bracket 1, the sealing structure 3 can effectively block the entry of external air, moisture, and dust into the interior of the vehicle - mounted refrigerator, protecting the transmission mechanism 2 and other precision components, and can extend the service life of the device. By providing the shock - absorbing structure 4 on the fixed bracket 1, the shock - absorbing structure 4 can effectively absorb the vibration generated during the operation of the transmission mechanism 2, reducing the generation of noise.

[0029] Furthermore, as Figures 1-4 shown, the shock - absorbing structure 4 includes a first shock - absorbing member 401, and the first shock - absorbing member 401 is provided at the front end of the fixed bracket 1.

[0030] Specifically, since the first shock - absorbing member 401 is provided at the front end of the fixed bracket 1, it can effectively buffer the vibration transmitted from the front end of the transmission mechanism 2 to the fixed bracket 1.

[0031] It should be noted that the first shock - absorbing member 401 is made of a highly elastic material (such as rubber, silicone, etc.).

[0032] Furthermore, as Figures 1-4 shown, the fixed bracket 1 is provided with a support portion 101. A first opening 1011 is provided on the support portion 101, and a first positioning groove 4011 is provided on the first shock - absorbing member 401. The first shock - absorbing member 401 is installed on the first opening 1011 through the first positioning groove 4011.

[0033] Specifically, the first shock - absorbing member 401 is installed in the first opening 1011 on the support portion 101 of the fixed bracket 1 through the first positioning groove 4011, ensuring that the first shock - absorbing member 401 is more firmly fixed on the fixed bracket 1, and avoiding the reduction of the shock - absorbing effect caused by the loosening or position deviation of the first shock - absorbing member 401.

[0034] Furthermore, as Figure 3As shown, the transmission mechanism 2 includes a driving motor 201. A fixing seat 102 matching the driving motor 201 is provided on the fixing bracket 1. A number of supporting parts 101 are provided, and the number of supporting parts 101 are evenly spaced on the outer peripheral edge of the fixing seat 102.

[0035] Specifically, by providing a plurality of evenly spaced supporting parts 101 on the fixing bracket 1 and arranging them around the outer peripheral edge of the fixing seat 102, the stability of the entire transmission mechanism 2 can be ensured; the existence of a plurality of supporting parts 101 can evenly share the load and vibration generated during the operation of the driving motor 201, avoiding structural deformation or damage caused by single-point stress.

[0036] Furthermore, as Figures 1-4 shown, the shock-absorbing structure 4 further includes a second shock-absorbing member 402, and the second shock-absorbing member 402 is provided on the rear end of the fixing bracket 1.

[0037] Specifically, the setting of the second shock-absorbing member 402 ensures that the fixing bracket 1 can evenly absorb vibrations from different directions during the operation of the transmission mechanism 2, preventing the concentration of vibration energy in a single direction, thereby further reducing the noise and vibration during the operation of the transmission mechanism 2.

[0038] It should be noted that the second shock-absorbing member 402 is made of high-elastic materials (such as rubber, silica gel, etc.).

[0039] Furthermore, as Figures 1-4 shown, a recess 103 is provided on the fixing bracket 1, a second positioning groove 4021 is provided on the second shock-absorbing member 402, a slot 1031 is provided on the recess 103 corresponding to the second positioning groove 4021, and the second shock-absorbing member 402 is installed on the slot 1031 through the second positioning groove 4021.

[0040] Specifically, the second shock-absorbing member 402 is in close fit with the slot 1031 on the fixing bracket 1 through the second positioning groove 4021; it can ensure that the second shock-absorbing member 402 remains stable during vibration and will not loosen or shift due to mechanical vibration, thus ensuring the continuity of the shock-absorbing effect.

[0041] Furthermore, as Figure 2 、 Figures 4-6 shown, the fixing bracket 1 is further provided with a positioning part 104 and a sliding part 105 extending outward. The sealing structure 3 includes a sealing member 301, and an opening 3011 is provided on the sealing member 301. The sealing member 301 passes through the sliding part 105 through the opening 3011 and is sleeved on the positioning part 104.

[0042] Specifically, the sealing member 301 is firmly fixed in place and can ensure good sealing effect during the operation of the transmission mechanism 2, preventing external air, moisture, and dust from entering it.

[0043] Furthermore, the transmission mechanism 2 further includes a coupling 202, a bearing 203 and a transmission screw 204. The coupling 202 and the bearing 203 are installed on the positioning portion 104, and the transmission screw 204 is installed on the sliding portion 105. One end of the output shaft of the driving motor 201 is connected to one end of the coupling 202, and one end of the transmission screw 204 is engaged with the bearing 203 and connected to the other end of the coupling 202.

[0044] Specifically, the setting of the coupling 202 makes the linkage between the driving motor 201 and the transmission screw 204 more precise; the driving motor 201 transmits power to the coupling 202 through the output shaft, and the coupling 202 drives the transmission screw 204 to rotate.

[0045] Furthermore, as Figure 2 、 Figures 4-6 shown, the seal 301 includes a flange 3012, and the flange 3012 is in sealing contact with the fixed bracket 1.

[0046] Specifically, since the flange 3012 is in direct sealing contact with the fixed bracket 1, it ensures the precise positioning of the seal 301 on the fixed bracket 1, and effectively prevents the fixed bracket 1 from directly contacting the main body of the vehicle-mounted refrigerator. The fixed bracket 1 contacts the main body of the vehicle-mounted refrigerator through the other end of the flange 3012, preventing direct friction or collision between the fixed bracket 1 and the refrigerator main body 7.

[0047] Furthermore, as Figure 2 、 Figures 4-6 shown, the seal 301 further includes a sealing portion 3013. The sealing portion 3013 wraps around the positioning portion 104. A positioning groove 30131 is provided on the sealing portion 3013, and the sealing portion 3013 is in sealing cooperation with the sliding portion 105 through the positioning groove 30131; the sealing portion 3013 is in a conical shape or a square shape.

[0048] Specifically, the design that the sealing portion 3013 wraps around the positioning portion 104 and is in sealing cooperation with the sliding portion 105 through the positioning groove 30131 can effectively seal the gap between the positioning portion and the sliding portion, preventing the intrusion of external air, dust, moisture, etc.; the sealing portion 3013 is in sealing cooperation with the sliding portion 105 through the positioning groove 30131. This design ensures the stability of the seal 301 in the device, preventing it from falling off or shifting due to vibration or mechanical stress. The conical or square-shaped sealing portion can provide a larger contact area and stronger stability, further improving the fixing effect of the seal.

[0049] It should be noted that the shape of the sealing portion 3013 can be changed according to the installation requirements and the spatial structure.

[0050] As Figure 7As shown in the figure, a vehicle-mounted refrigerator includes a vehicle-mounted refrigerator main body and a drawer 8 provided on the vehicle-mounted refrigerator main body. The vehicle-mounted refrigerator main body is provided with the above-mentioned transmission bracket with sealing and shock-absorbing functions.

[0051] Specifically, through the transmission bracket with sealing and shock-absorbing functions, the sealing structure 3 of the vehicle-mounted refrigerator main body ensures the isolation between the internal environment of the refrigerator and the external environment; the shock-absorbing structure 4 absorbs and buffers the vibration generated by the transmission mechanism 2.
