Description

Technical Field

[0001] The utility model relates to the technical field of the transmission structure of a drawer of a vehicle-mounted refrigerator, in particular to a fixing structure for a new energy vehicle-mounted refrigerator drawer and a transmission belt. This vehicle-mounted refrigerator is also applicable to fuel vehicles. Background Art

[0002] In the full-automatic door opening and closing of existing vehicle-mounted refrigerators, some adopt a structure in which a rope is used to pull the drawer to move. When the rope pulls the drawer, firstly, the rope has relatively high toughness requirements. Secondly, the rope needs to be wound up, and such a winding structure will cause the volume of the refrigerator to increase. For example, Chinese Patent No. ZL202410673540.X discloses a rope-type full-automatic drawer drive structure applied to a vehicle-mounted refrigerator, which includes a box body assembly and a compressor module box; the full-automatic drawer track includes an equipment bottom plate, a slide rail, a driven turntable, a fixed base, a driving turntable, a motor, a rope, a rope assembly, a front photoelectric sensor, a rear photoelectric sensor, and a drawer drive connecting piece; a pair of slide rails are respectively fixed on the left and right sides of the equipment bottom plate, a driven turntable is arranged at the front end of the middle of the equipment bottom plate, and a drawer drive connecting piece is arranged on the left side of the equipment bottom plate; the tail of the equipment bottom plate is connected with a fixed base, a driving turntable is arranged at the upper end of the fixed base, and the driving turntable is connected with the motor at the tail of the fixed base; a rope assembly is connected between the driven turntable and the driving turntable; the rope assembly is composed of a rope, an internal thread socket and an adjusting bolt; the rope is sleeved on the driven turntable and the driving turntable, and the two ends of the rope are respectively connected with the two ends of the drawer drive connecting piece. The internal thread socket and the adjusting bolt are respectively connected to the middle of the rope, and the tightness is adjusted by the screwing depth of the adjusting bolt. Therefore, the rope-type full-automatic drawer drive structure of this vehicle-mounted refrigerator is large in volume and occupies a large installation space inside the refrigerator.

[0003] Moreover, its slide rail assembly is horizontally arranged. When the vehicle is driving on a bumpy road section, if the drawer is not provided with a locking structure, the drawer is likely to slide back and forth through the slide rail assembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing structure for a new energy vehicle-mounted refrigerator drawer and a transmission belt. By adopting a belt drive mode to drive the drawer to move, a full-automatic door opening and closing structure of the vehicle-mounted refrigerator is realized, the mechanical transmission structures such as a lead screw and a gear that require lubricating oil are cancelled, and the transmission structure that uses a rope to pull the drawer in the prior art is cancelled, and the winding structure is cancelled, so as to simplify the full-automatic door opening and closing transmission structure of the vehicle-mounted refrigerator and effectively save the installation space of the refrigerator.

[0005] The purpose of the utility model is realized as follows:

[0006] A fixed structure for a new energy vehicle-mounted refrigerator drawer and a transmission belt, including a clamping assembly arranged at the bottom of the refrigerator drawer for clamping the transmission belt. The clamping assembly includes a pressing block and a locking block for clamping the transmission belt. The pressing block is connected to the locking block. The clamping assembly and the transmission belt are in a locked and fixed state, so that the refrigerator drawer is fixedly connected to the transmission belt, and the transmission belt drives the refrigerator drawer to move when it runs.

[0007] By adopting a belt drive method to drive the drawer to move, a fully automatic door opening and closing structure of the vehicle-mounted refrigerator is realized. Mechanical transmission structures such as lead screws and gears that require lubricating oil are cancelled, and the transmission structure that uses ropes to pull the drawer in the prior art is cancelled, and the winding structure is cancelled, simplifying the fully automatic door opening and closing transmission structure of the vehicle-mounted refrigerator, effectively saving the installation space of the refrigerator, and further reducing costs. The clamping assembly for clamping and fixing the transmission belt is assembled by the pressing block and the locking block, with low production cost and convenient installation. The transmission belt made of materials with good wear resistance has high durability and a long service life.

[0008] A bite anti-slip part is provided between the clamping assembly and the transmission belt. The clamping assembly and the transmission belt are bite-connected through the bite anti-slip part. When the transmission belt runs, the clamping assembly moves along with the transmission belt through the bite anti-slip part. By setting the bite anti-slip part, it is possible to prevent the clamping assembly from slipping on the transmission belt when the transmission belt runs, and avoid the situation where the clamping assembly cannot move along with the transmission belt.

[0009] A number of spaced bite teeth are provided on the transmission belt. The locking block is provided with a number of spaced tooth grooves corresponding to the bite teeth. When the clamping assembly and the transmission belt are in a locked and fixed state, some of the bite teeth of the transmission belt are correspondingly limited in the corresponding tooth grooves, and the bite teeth and the tooth grooves form the bite anti-slip part between the clamping assembly and the transmission belt, effectively fixing the connection between the drawer and the transmission belt.

[0010] A connection part is provided between the pressing block and the locking block. The clamping assembly clamps the transmission belt, and the pressing block and the locking block are connected through the connection part, so that the clamping assembly and the transmission belt are in a locked and fixed state, effectively locking the transmission belt on the clamping assembly, preventing the transmission belt from slipping out of the clamping assembly, and preventing loosening between the clamping assembly and the transmission belt.

[0011] The refrigerator drawer is reciprocally movably arranged in the refrigerator inner liner. A slide rail assembly is provided between the refrigerator drawer and the refrigerator inner liner. The refrigerator drawer is supported on the slide rail assembly and is suspended on the inner cavity bottom wall of the refrigerator inner liner;

[0012] An installation interval is formed between the bottom of the refrigerator drawer and the upper part of the inner cavity bottom wall of the refrigerator liner. The connections between the clamping assembly and the transmission belt, and between the pressing block and the locking block are all located in the installation interval, effectively utilizing the vertical interval between the refrigerator drawer and the refrigerator liner to install the transmission structure of the transmission belt. The installation space inside the refrigerator is compact, the volume of the refrigerator is small, the overall volume of the in-vehicle refrigerator is effectively reduced, and this installation interval also facilitates the fixed connection between the pressing block and the locking block.

[0013] The slide rail assembly includes a bracket and a slide rail component. A support plate is provided at the bottom of the refrigerator drawer. An installation gap for installing the slide rail component is formed between the support plate and the bracket. The bracket is also located in the vertical interval between the refrigerator drawer and the refrigerator liner. The slide rail component is installed between the bottom of the refrigerator drawer and the support plate, reasonably utilizing the interval between the bottom of the refrigerator drawer and the support plate. And an installation cavity for accommodating the installation of the transmission belt and the passive wheel, etc. is formed between the middle part of the support plate and the bottom of the refrigerator drawer. The installation space inside the refrigerator is compact, the volume of the refrigerator is small, and the overall volume of the in-vehicle refrigerator is effectively reduced.

[0014] The slide rail component is inclinedly arranged on the installation gap, canceling the existing state of horizontally arranging the slide rail component. The opening and closing direction of the slide rail component is inclinedly limited on the installation gap. When the vehicle is driving on a bumpy road section, the drawer is not easy to slide back and forth through the slide rail component, and the anti-bump performance is good.

[0015] The pressing block protrudes from the bottom of the refrigerator drawer.

[0016] There are two limit blocks arranged at intervals between the pressing block and the locking block. The clamping assembly clamps the transmission belt, and the transmission belt is limited between the two limit blocks. This avoids the phenomenon of the transmission belt deflecting when running on the clamping assembly.

[0017] One end of the transmission belt is in transmission connection with the driving wheel, and the other end of the transmission belt is in transmission connection with the passive wheel. The passive wheel is rotatably arranged on a support member. There is a front-back position adjustment structure between the support member and the in-vehicle refrigerator. The front-back position of the support member on the in-vehicle refrigerator is adjusted through the front-back position adjustment structure to adjust the front-back distance between the driving wheel and the passive wheel, and further adjust the tightness of the transmission belt; the driving wheel is in transmission connection with the driving shaft of the driving motor.

[0018] By setting the front-back position adjustment structure, the structure of using a tensioning wheel to adjust the tightness of the transmission belt is canceled, further reducing the production cost, and simplifying the structure for adjusting the tightness of the transmission belt, further saving the installation space inside the refrigerator.

[0019] The beneficial effects of the present utility model are as follows:

[0020] By adopting a belt drive method to drive the drawer to move, a fully automatic door opening and closing structure of the in-vehicle refrigerator is realized, eliminating mechanical drive structures such as lead screws and gears that require lubricating oil, avoiding the high viscosity of lubricating oil in low-temperature environments that hinders mechanical drive. Now, with the belt drive method, lubricating oil is not required.

[0021] In addition, the drive structure that uses a rope to pull the drawer in the prior art is eliminated, and the winding structure is removed, simplifying the fully automatic door opening and closing drive structure of the in-vehicle refrigerator, effectively saving the installation space of the refrigerator, and further reducing costs. The clamping assembly that clamps and fixes the drive belt is assembled by a pressing block and a locking block, with low production costs and convenient installation. The drive belt made of a material with good wear resistance has high durability and a long service life. Brief Description of the Drawings

[0037] In this embodiment, two support plates 13 arranged at intervals are provided on the bottom of the refrigerator drawer 1, and the support plates 13 are inclinedly arranged on the bottom of the refrigerator drawer 1.

[0038] In this embodiment, the bracket 11 is provided with inclined plates 20 corresponding to two inclined support plates 13 at the bottom of the refrigerator. A flat plate 21 is provided between the two inclined plates 20, effectively increasing the mechanical strength of the bracket 11.

[0039] The slide rail component is inclinedly arranged between the corresponding inclined plates 20 and the support plates 13. The slide rail component includes a moving rail slidably arranged on a fixed rail.

[0040] The pressing block 3 protrudes from the bottom of the refrigerator drawer 1. The refrigerator drawer 1 is provided with a protruding pressing block 3. The pressing block 3 and the refrigerator drawer 1 can be set as a whole through relevant processes, which is simple in processing and shortens the product production and processing cycle.

[0041] There are two spacing - arranged limit blocks 12 between the briquetting block 3 and the locking block 5. The clamping assembly 2 clamps the transmission belt 4, and the transmission belt 4 is limited between the two limit blocks 12.

[0042] In this embodiment, the locking block 5 is provided with a limit block 12 extending towards the top of the briquetting block 3, and the top of the limit block 12 can abut against the bottom of the refrigerator drawer 1 to reduce the assembly gap between the locking block 5 and the bottom of the refrigerator drawer 1.
