[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the 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 violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] like Figures 1-6 As shown, a transmission support structure and a vehicle refrigerator are provided, the transmission support structure includes a fixed support 1 and a transmission mechanism 2 installed on the fixed support 1, the transmission mechanism 2 includes a drive motor 201 and a transfer assembly 202 that is transmission-connected to the output shaft of the drive motor 201, a first installation area 101 on the fixed support 1 for installing the drive motor 201 and a second installation area 102 for installing the transfer assembly 202.

[0028] Specifically, the transmission mechanism 2 is integrated together for modular assembly through the fixed bracket 1, thereby improving production and assembly efficiency and accuracy and effectively reducing costs. Since the drive motor 201 and the transfer component 202 are fixed on the same fixed bracket 1, the relative position accuracy between the two can be ensured, ensuring the stability and accuracy of the transmission process and reducing vibration and noise problems caused by insufficient installation accuracy.

[0029] Further, if Figures 1-3 and Figure 6 As shown, a fixing seat 1011 matching the driving motor 201 is disposed on the first installation area 101 , and at least a portion of the driving motor 201 is located on the fixing seat 1011 .

[0030] Specifically, the setting of the fixed seat 1011 effectively reduces the looseness or position deviation caused by the vibration of the drive motor 201, further improves the operating stability of the device, and the vibration of the drive motor 201 is effectively absorbed by the fixed seat 1011 and transmitted to the fixed bracket 1, rather than directly affecting the entire transmission mechanism, ensuring that the relative position of the drive motor 201 and the transfer assembly 202 always remains stable, thereby ensuring the smooth operation of the transfer assembly 202.

[0031] Further, if Figures 1-4 As shown, a plurality of connecting parts 1012 are provided on the outer peripheral edge of the fixing seat 1011 ; a first shock absorbing member 3 is provided on the connecting part 1012 , a through hole 10121 is provided on the connecting part 1012 , and the first shock absorbing member 3 is installed on the through hole 10121 .

[0032] Specifically, when the drive motor 201 operates, vibrations are first transmitted to the fixed seat 1011 and then to the shock absorber 3 through the connecting part 1012. The shock absorber 3 can absorb and attenuate the vibrations generated during the operation of the drive motor 201.

[0033] Furthermore, as Figures 1-4 shown, the transfer assembly 202 includes a coupling 2021 and a bearing 2022. The second installation area 102 is provided with a positioning part 1021 for installing the coupling 2021 and the bearing 2022. The positioning part 1021 is provided with a rib 10211 that tightly fits with the drive motor 201. One end of the output shaft of the drive motor 201 is connected to the coupling 2021.

[0034] Specifically, the positioning part 1021 on the second installation area 102 functions to fix and position the coupling 2021 and the bearing 2022, ensuring the precise position of the coupling 2021 and the bearing 2022 during installation, thereby avoiding the problem of misalignment of the axes caused by installation deviation; and the setting of the rib 10211 can ensure the tight fit between the drive motor 201 and the positioning part 1021, preventing the drive motor 201 from shifting during operation.

[0035] Furthermore, as Figures 1-4 shown, the transfer assembly 202 further includes a transmission screw 2023. The second installation area 102 is further provided with a guiding part 1022. The guiding part 1022 is provided with a sliding groove 1023. The transmission screw 2023 is located on the sliding groove 1023. The bearing 2022 is sleeved on one end of the transmission screw 2023, and one end of the transmission screw 2023 is drivingly connected to the other end of the coupling 2021.

[0036] Specifically, the guiding function of the sliding groove 1023 for the transmission screw 2023 ensures that the screw maintains an accurate linear movement path during operation; the setting of the bearing 2022 reduces the direct friction between the transmission screw 2023 and other structural parts; when the drive motor 201 rotates, the rotational motion is transmitted to the transmission screw 2023 through the coupling 2021, realizing the rotation of the transmission screw 2023.

[0037] Furthermore, as Figures 1-3 and Figure 6 shown, the transmission support structure further includes a bushing 4. The guiding part 1022 is provided with a positioning seat 1024. The bushing 4 is provided with a buckle 401. The bushing 4 is installed on the positioning seat 1024 through the buckle 401. The other end of the transmission screw 2023 is connected to the bushing 4.

[0038] Specifically, the setting of the bushing 4 enables the drive screw 2023 to rotate stably within the chute 1023, avoiding the swing or deviation of the drive screw 2023 caused by unilateral support, and enabling the drive screw 2023 to maintain better axial alignment during movement; the bushing 4 is installed on the positioning seat 1024 through the buckle 401, making the installation and disassembly process simpler and faster.

[0039] Furthermore, as Figures 1-3 and Figure 6 shown, the drive support structure further includes a second shock absorber 5, and a slot 1022a for installing the second shock absorber 5 is provided on the guiding portion 1022.

[0040] Specifically, the second shock absorber 5 can effectively absorb the vibration generated by the drive screw 2023 during operation, further reducing the noise of the drive system during operation; when the drive motor 201 drives the drive screw 2023 through the coupling 2021, the drive screw 2023 may generate certain vibrations during rotation, and these vibrations are transmitted through the bearing 2022 and the guiding portion 1022. However, due to the presence of the second shock absorber 5, these vibrations are effectively attenuated before being transmitted to other components, thereby reducing the negative impact on the entire system.

[0041] Furthermore, as Figure 4 and Figure 6 shown, a number of reinforcing ribs 6 are provided at intervals between the guiding portion 1022 and the fixed seat 1011.

[0042] Specifically, the main function of the reinforcing ribs 6 is to provide additional support between the guiding portion 1022 and the fixed seat 1011, enhancing the connection strength and stability between the two; when the drive screw 2023 is operating, the generated stress is effectively dispersed through the reinforcing ribs 6, reducing the possibility that the guiding portion 1022 and the fixed seat 1011 bear excessive stress alone.

[0043] Furthermore, as Figure 5 shown, a number of ribs 1013 are provided at intervals on the fixed seat 1011.

[0044] Specifically, the ribs 1013 are located inside the fixed seat 1011 and are in contact with the drive motor 201. When the drive motor 201 is working, it can absorb and buffer part of the vibration generated by the drive motor 201 during operation, thereby reducing the vibration and noise levels of the entire system and improving the running smoothness of the system.

[0045] Furthermore, the fixed bracket 1 is made of nylon and fiberglass materials.

[0046] As Figure 7As shown in the figure, a vehicle-mounted refrigerator includes a vehicle-mounted refrigerator main body and a drawer 7 provided on the vehicle-mounted refrigerator main body, and the above-mentioned transmission bracket structure is provided on the vehicle-mounted refrigerator main body.

[0047] Specifically, the driving motor 201, the transfer assembly 202, the first shock absorber 3 and the second shock absorber 5 are installed on the fixed bracket 1, and then the fixed bracket 1 is installed on the vehicle-mounted refrigerator main body, so that the driving motor 201 drives the transmission screw 2023 to rotate through the coupling 2021. The rotation of the transmission screw 2023 enables the drawer 7 to move smoothly back and forth on the vehicle-mounted refrigerator main body; the setting of the first shock absorber 3 and the second shock absorber 5 absorbs and buffers the possible vibrations when the driving motor 201 and the transmission screw 2023 operate, reducing the possibility of vibration being transmitted to the vehicle-mounted refrigerator main body, thereby improving the smoothness of the system and the user experience.
