[0029] First, the existing vehicle refrigerator will be described.

[0030] At present, the car refrigerators on the market are manual and semi-automatic. The manual car refrigerators simply slide on the slide rail when the drawer is pulled out and pushed back. The semi-automatic ones add an additional pop-up mechanism on the slide rail to make the refrigerator drawer pop out a certain distance. When the above two types of car refrigerators are on a steep slope and the car refrigerator door is open, the refrigerator drawer will move back and forth, which may accidentally pinch or hit people, giving people an extremely uncomfortable experience. It can be seen that there are many inconveniences in the user experience of existing car refrigerators, so electric drawer car refrigerators have emerged. At present, most of the electric drawer car refrigerators on the market are pulled out or pushed back by buttons, and some are realized by voice control. These methods all realize the electric control of the refrigerator drawer and improve the user experience, but the operation method is relatively simple. For this reason, the following implementation methods are proposed.

[0031] Embodiment 1

[0032] like Figure 1-Figure 5 As shown, in order to solve the problems that the drawer 1 of the existing vehicle refrigerator is inconvenient to use and has a single operation method, the drawer 1 for the vehicle refrigerator of the utility model includes:

A support spring 1223 is provided between the mounting bracket 1222 and the second slide rail 122, and the roller 1221 is fixedly provided with a roller 1221 on the second slide rail 122 through a mounting bracket 1222. 23 abuts against the third slide rail 111 and can roll along the third slide rail 111, a first limiting structure (not shown in the figure) is provided between the second slide rail 122 and the third slide rail 111, so that when the drawer body 11 is pulled out to the first position, the second slide rail 122 and the third slide rail 111 slide together along the first slide rail 121 under the action of the first limiting structure, and a second limiting structure is provided between the second slide rail 122 and the first slide rail 121, so that when the drawer body 11 is pulled out to the second position, the drawer body 11, the third slide rail 111 and the second slide rail 122 can stop moving under the action of the second limiting structure.

[0034] The electromagnetic induction device includes a magnetic field source and a conductor. The magnetic field source is a magnet 131 arranged on a roller 1221, and the conductor is a wire 132 fixedly arranged on a drawer shell 12. The wire 132 is communicatively connected with a controller of the vehicle refrigerator.

[0035] A driving device and a movable component 15, the driving device includes a driving motor 141, a driving wheel 142 and a driven wheel 143, the driving wheel 142 is connected to the output end of the driving motor 141, the driven wheel 143 is fixedly arranged on the drawer shell 12, a transmission belt 144 is connected between the driving wheel 142 and the driven wheel 143, the movable component 15 is arranged on the transmission path of the transmission belt 144, the movable component 15 includes a movable frame 151, a first compression spring 152 and a second compression spring 153, the movable frame 151 is fixedly connected to the drawer body 11, the first compression spring 152 and the second compression spring 153 are arranged inside the movable frame 151 and are respectively abutted against the inner side walls at both ends of the movable frame 151 under the pulling of the transmission belt 144, the first compression spring 152 and the second compression spring 153 are staggered in the vertical direction, and there is an overlapping part in the projection of the first compression spring 152 and the second compression spring 153 in the vertical direction.

[0036] In the case of adopting the above embodiment, during the process of pulling out the drawer 1 of the vehicle refrigerator of the utility model, the user first slightly pulls the drawer body 11 outward, and the drawer body 11 drives the movable frame 151 of the movable assembly 15 to move outward (i.e. Figure 3The first compression spring 152 is in the relaxed state, and the second compression spring 153 is squeezed by the movable frame 151 and is in the compressed state (the deformation of the second compression spring 153 is the moving distance of the drawer body 11). The drawer body 11 and the third slide rail 111 move outwards. Since a support spring 1223 is provided between the mounting bracket 1222 of the roller 1221 and the second slide rail 122, the roller 1221 will abut against the third slide rail 111 under the action of the support spring 1223. At the same time, the roller 1221 will roll along the third slide rail 111 driven by the drawer body 11. Since a magnet 131 is provided on the roller 1221, when the roller 1221 rolls, it drives the magnet 131 to roll together. The rolling of the magnet 131 causes the direction of the magnetic field generated by the magnet 131 to The direction changes, so that the wire 132 fixed on the drawer shell 12 cuts the magnetic flux lines to generate an induced electromotive force. The wire 132 is connected to an amplifying circuit. The induced electromotive force is processed by the amplifying circuit to obtain a voltage signal. After receiving the voltage signal, the controller of the vehicle refrigerator can determine that the user needs to pull out the drawer 1 according to the positive and negative directions of the voltage signal, thereby controlling the driving device to drive the driving wheel 142 to rotate, and then drives the driven wheel 143 to rotate through the transmission belt 144, and at the same time drives the movable frame 151 to move through the transmission belt 144 and finally drives the drawer 1 to be pulled out. When the drawer body 11 is pulled out to the first position, the roller 1221 on the second slide rail 122 rolls along the third slide rail 111, and the third slide rail 111 moves outward relative to the second slide rail 122. At the same time, the second slide rail 122 does not move relative to the first slide rail 121. When the drawer body 11 is pulled out to the first position, the first limit structure between the second slide rail 122 and the third slide rail 111 is triggered. At this time, the third slide rail 111 no longer moves relative to the second slide rail 122, but the third slide rail 111 drives the second slide rail 122 to slide outward along the first slide rail 121. When the drawer body 11 is pulled out to the second position, the second slide rail 122 and the first limit structure are The second limiting structure between the slide rails 121 is triggered, and at this time the second slide rail 122 no longer moves relative to the first slide rail 121, but the drawer body 11, the third slide rail 111 and the second slide rail 122 do not move relative to the first slide rail 121 under the action of the second limiting structure (i.e., stop being pulled out), wherein the first limiting structure and the second limiting structure can be baffles, and when the drawer body 11 is pulled out to the first position, the baffle of the third slide rail 111 abuts against the second slide rail 122, and when the drawer body 11 is pulled out to the second position, the baffle of the second slide rail 122 abuts against the first slide rail 121, or other common limiting structures, the utility model does not make specific restrictions.

[0037] The advantages of the above-mentioned setting method are: the induced electromotive force generated by the electromagnetic induction device is used as a trigger signal to control the driving device, and the movable component 15 is arranged on the transmission path between the driving device and the drawer body 11 to provide a movable space for the electromagnetic induction device to generate the induced electromotive force. The structure is simple and easy to operate, which solves the problems that the drawer 1 of the existing vehicle refrigerator is inconvenient to use and the operation method is single. In addition, by arranging a support spring 1223 between the mounting bracket 1222 and the second slide rail 122, it is ensured that the roller 1221 can abut against the third slide rail 111 at the bottom of the drawer body 11 to prevent the roller 1221 from idling. By arranging the first slide rail 121, the second slide rail 122 and the third slide rail 111 and the first limiting structure and the second limiting structure, the drawer body 11 can be prevented from tilting and being pulled out excessively and falling during the process of drawing out the drawer 1. By staggering the first compression spring 152 and the second compression spring 153 in the vertical direction, the size of the movable frame 151 can be reduced, and the space occupied can be reduced. It is also worth mentioning that the above-mentioned process of pulling out the drawer 1 is described in detail. The triggering mode and working principle of the electromagnetic induction device during the pushing-in process of the drawer 1 are similar to those during the pulling-out process, and will not be repeated here.

[0038] In another possible implementation, different from the aforementioned first embodiment, a slide rail is provided at the bottom of the drawer shell 12, a roller 1221 is provided at the bottom of the drawer body 11, the roller 1221 can roll on the slide rail, a magnet 131 is provided on the roller 1221, a wire 132 is fixedly provided on the drawer shell 12, and the wire 132 and the drive device are connected to the controller of the vehicle refrigerator. Thus, when the drawer 1 is pulled out, the user slightly pulls the drawer 1, the roller 1221 at the bottom of the drawer 1 rolls along the slide rail at the bottom of the drawer shell 12, the magnetic field generated by the magnet 131 on the roller 1221 changes, and the wire 132 on the drawer shell 12 cuts the magnetic flux lines to generate an induced electromotive force, thereby triggering the controller of the vehicle refrigerator to control the drive device to drive the drawer 1 to be pulled out.

[0039] In addition, in a possible implementation, a person skilled in the art may also fix the magnet 131 on the drawer housing 12, and simultaneously set the wire 132 on the drawer body 11. When the user slightly pulls the drawer 1, the wire 132 on the drawer body 11 can cut the magnetic lines of force to generate an induced electromotive force. These changes do not exceed the technical principles of the present invention, and therefore will also be included in the protection scope of the present invention.

[0040] Embodiment 2

[0041] In a possible embodiment, the driving device includes a driving motor 141, a driving wheel 142 and a driven wheel 143, the driving wheel 142 is connected to the output end of the driving motor 141, the driven wheel 143 is fixedly arranged on the drawer shell 12, and a transmission belt 144 is connected between the driving wheel 142 and the driven wheel 143; the movable component 15 is arranged on the transmission path of the transmission belt 144, the movable component 15 includes a movable frame 151, a first tension spring and a second tension spring (not shown in the figure), the movable frame 151 is fixedly connected to the drawer body 11, the first tension spring and the second tension spring are arranged on the outside of the movable frame 151, the first ends of the first tension spring and the second tension spring are respectively connected to the outer side walls at both ends of the movable frame 151, and the second ends are respectively connected to the transmission belt 144.

When the user needs to pull out or push the drawer 1, the user slightly pulls or pushes the drawer body 11, and the drawer body 11 will drive the movable frame 151 to compress the first tension spring or the second tension spring. The compression amount of the first tension spring or the second tension spring is the movement amount of the drawer body 11, so that the conductor cuts the magnetic flux lines to generate an induced electromotive force, which triggers the controller to drive the drive device to drive the drawer 1 to be pulled out or pushed in.

[0043] In a possible embodiment, the driving device is a cylinder and a transmission rod. The transmission rod is provided with a waist hole along the pulling direction of the drawer 1. The drawer body 11 is provided with a protrusion, and the protrusion is movably arranged in the waist hole. When the drawer 1 needs to be pulled out, the user slightly pulls the drawer body 11. At this time, the protrusion on the drawer body 11 slides in the waist hole on the transmission rod. The transmission rod does not move. The conductor cuts the magnetic flux lines to generate an induced electromotive force, which triggers the controller to drive the driving device to drive the drawer 1 to be pulled out. During the driving process, the transmission rod moves outward until the protrusion abuts against the side of the waist hole. The transmission rod continues to move outward to drive the protrusion and then the drawer body 11 to be pulled out. The process of pushing in the drawer 1 is similar to the process of pulling out, which will not be repeated here.
