[0031] like Figures 1 to 8 As shown, the embodiment of the utility model provides a vehicle-mounted cold and warm box, including a box body 11, a drawer body 21 and a connecting assembly, and the drawer body 21 is connected to the box body 11 in a push-pull manner through the connecting assembly. Users can modify the opening and closing mode of the vehicle-mounted cold and warm box of the utility model to electric opening and closing, electric opening and manual closing, and manual opening and closing according to actual needs.

[0032] When the vehicle-mounted heating and cooling box is opened and closed manually, Figure 1 As shown, the connecting component includes a first connecting member 33 and a second connecting member 34. Specifically, the first connecting member 33 and the second connecting member 34 are plate structures, and can also be structures that can provide installation locations such as frame structures or grid structures. The first connecting member 33 and the second connecting member 34 can be used in electrically opened and closed and electrically opened and manually closed heating and cooling boxes. The first connecting member 33 is detachably connected to the box body 11. For example, the box body 11 has a screw hole, and the box body 11 and the first connecting member 33 are detachably screwed by means of screws and screw holes. The second connecting member 34 is detachably connected to the drawer body 21. For example, the drawer body 21 has a screw hole, and the drawer body 21 and the second connecting member 34 are detachably screwed by means of screws and screw holes. The first connecting member 33 and the second connecting member 34 are slidably connected, such as by arranging a pulley or a slide rail 4 on the second connecting member 34 to achieve the sliding of the second connecting member 34 relative to the first connecting member 33. At the same time, a structure that can achieve the locking of the drawer body 21 and the box body 11 can be configured. Since the existing technology corresponding to the structure is relatively mature, it is not repeated here. Through the above arrangement, the user can move the drawer body 21 out of and into the interior of the box body 11 by manually pushing and pulling.

[0033] For some users, manually opened and closed heating and cooling boxes are rather cumbersome to operate. If economic conditions permit, users have the need to upgrade manually opened and closed heating and cooling boxes to electrically opened and closed, or electrically opened and manually closed heating and cooling boxes.

[0034] When the opening and closing mode of the vehicle-mounted heating and cooling box is electric opening and closing or electric opening and manual closing, the connecting component includes a first connecting member 33, a second connecting member 34 and a moving mechanism. Specifically, the first connecting member 33 and the second connecting member 34 are plate structures, and can also be structures that can provide installation locations such as frame structures or grid structures. The first connecting member 33 and the second connecting member 34 can be used in a manually opened and closed heating and cooling box. The first connecting member 33 is detachably connected to the box body 11. If the box body 11 has a screw hole, the box body 11 and the first connecting member 33 are detachably screwed together with screws and screw holes. The second connecting member 34 is detachably connected to the drawer body 21. If the drawer body 21 has a screw hole, the drawer body 21 and the second connecting member 34 are detachably screwed together with screws and screw holes. The second connecting member 34 is slidably connected to the first connecting member 33 through a moving mechanism. For the content of the sliding setting, please refer to the above-mentioned manual opening and closing heating and cooling box, which will not be repeated here. Through the above arrangement, the user can electrically move the drawer body 21 out of and / or into the interior of the box body 11 with the aid of the motion mechanism.

[0035] When the vehicle-mounted heating and cooling box is opened and closed electrically, Figures 2 to 4 As shown, the motion mechanism is a first motion mechanism 31, and the first motion mechanism 31 includes a driving device 311 and a transmission mechanism 312. The driving device 311 is connected to the transmission mechanism 312, and the transmission mechanism 312 is respectively connected to the first connecting member 33 and the second connecting member 34. Through the above arrangement, the user can move the drawer body 21 out of and into the interior of the box body 11 by means of the first motion mechanism 31 through electric pushing and pulling.

[0036] In some specific embodiments, Figures 2 to 4 As shown, the transmission mechanism 312 includes a driving wheel 3121, a driven wheel 3122, a rope 3123 and a driven part 341; the driving wheel 3121 is arranged at a position close to the back wall of the box body 11, and the driving wheel 3121 is connected to the driving device 311, and the driving device 311 is a driving motor; the driven wheel 3122 is installed at a position of the first connecting member 33 away from the driving wheel 3121; the rope 3123 frictionally connects the driving wheel 3121 and the driven wheel 3122; the driven part 341 is fixedly connected to the second connecting member 34 or formed on the second connecting member 34, and the driven part 341 is also fixedly connected to the rope 3123, so that when the driving wheel 3121 drives the rope 3123 to move in the push-pull direction, the driven part 341 can drive the second connecting member 34 to move in the push-pull direction. When the drawer body 21 needs to be moved into the interior of the box body 11, as shown in FIG. Figure 3 to Figure 4 As shown, the driving wheel 3121 rotates clockwise to move the driven part 341 to the right along the push-pull direction, so that the drawer body 21 moves into the interior of the box body 11. When the drawer body 21 needs to be moved out of the interior of the box body 11, as shown in FIG. Figure 3 to Figure 4As shown, the driving wheel 3121 rotates counterclockwise to move the driven portion 341 to the left along the push-pull direction, thereby moving the drawer body 21 out of the interior of the box body 11 .

[0037] In some specific embodiments, Figure 2 As shown, the back wall of the box body 11 is provided with a through hole 111, the driving device 311 is arranged on the outside of the back wall, and the transmission mechanism 312 passes through the through hole 111 to transmit power to the second connecting member 34. Through the above arrangement, the driving device 311 is located outside the box body 11, thereby avoiding the driving device 311 occupying the internal space of the box body 11, thereby increasing the accommodation space inside the box body 11 and improving the space utilization rate inside the box body 11. If it is necessary to transform the above-mentioned heating and cooling box into a manual opening and closing type, as shown in FIG. Figure 1 As shown, the through hole 111 is detachably installed with a blocking piece 112, and the blocking piece 112 is used to block the through hole 111, so that the interior of the box body 11 is sealed to avoid leakage of cold or heat inside the box body 11 and improve the thermal insulation performance of the box body 11. Specifically, the blocking piece 112 is a heat-insulating blocking piece 112.

[0038] In some specific embodiments, Figure 2 As shown, the connecting assembly further includes a bracket 35, and the driving device 311 is arranged on the outer side of the back wall by means of the bracket 35; specifically, as shown in FIG. Figure 2 As shown, the bracket 35 is a plate structure, and the bracket 35 can also be a frame structure or a grid structure or other structures that can support the driving device 311.

[0039] When the vehicle-mounted heating and cooling box is opened and closed electrically and closed manually, Figures 5 to 8 As shown, the motion mechanism is the second motion mechanism 32, and the second motion mechanism 32 includes an elastic member 321 and a locking mechanism 322. One end of the elastic member 321 is fixedly connected to the first connecting member 33, and the other end is fixedly connected to the second connecting member 34 or is arranged corresponding to the second connecting member 34. The locking mechanism 322 can switch between a locking state and an unlocking state. The locking mechanism 322 includes a locking hook 32224. When the locking mechanism 322 is in the locking state, the locking hook 32224 is engaged with the second connecting member 34 and the elastic member 321 is in a compressed state. When the locking mechanism 322 is in the unlocking state, the locking hook 32224 is disengaged from the second connecting member 34, so as to drive the drawer body 21 to pop out of the box body 11 with the help of the restoring force of the elastic member 321. Through the above arrangement, the user can electrically move the drawer body 21 out of the box body 11 with the help of the second motion mechanism 32; the user can manually move the drawer body 21 into the box body 11.

[0040] In some specific embodiments, Figures 5 to 8As shown, the locking mechanism 322 includes a telescopic device 3221, a locking link 3222 and a return spring 323. The telescopic device 3221 is installed on the first connecting member 33. The telescopic device 3221 is an electric telescopic rod. The locking link 3222 includes a first rod portion 32221, a second rod portion 32222 and a rotating portion 32223. The locking hook 32224 is arranged at the first rod portion 32221. The rotating portion 32223 is located between the first rod portion 32221 and the second rod portion 32222. The first rod portion 32221 and the second rod portion 32222 are arranged at an angle. The lock link 3222 is rotatably mounted on the first connecting member 33 by means of the rotating portion 32223. One end of the return spring 323 is fixedly connected to the second rod portion 32222, and the other end is fixedly connected to the first connecting member 33. The telescopic end of the telescopic device 3221 is correspondingly arranged with the second rod portion 32222. When the lock mechanism 322 is in the unlocked state, the telescopic end of the telescopic device 3221 pushes the second rod portion 32222 to make the first rod portion 32221 rotate around the rotating portion 32223 as the rotation center, thereby disengaging the lock hook 32224 from the second connecting member 34. When the drawer body 21 needs to be moved out of the interior of the box body 11, as shown in FIG. Figure 6 to Figure 7 As shown, the locking mechanism 322 is switched to the unlocked state, and the telescopic end of the telescopic device 3221 pushes the second rod portion 32222 to make the first rod portion 32221 rotate clockwise with the rotating portion 32223 as the rotation center, so that the lock hook 32224 is disengaged from the second connecting member 34, and the restoring force of the elastic member 321 is used to drive the drawer body 21 to pop out of the box body 11, thereby moving the drawer body 21 out of the interior of the box body 11.

[0041] In some specific embodiments, Figure 8 As shown, the locking mechanism 322 also includes a locking portion 342, which is fixedly connected to the second connecting member 34 or formed on the second connecting member 34, and the locking portion 342 is correspondingly arranged with a locking hook 32224. When the locking mechanism 322 is in a locked state, the locking hook 32224 is engaged with the locking portion 342, and when the locking mechanism 322 is in an unlocked state, the locking hook 32224 is disengaged from the locking portion 342. The locking hook 32224 has a first guiding slope 32225, and the locking portion 342 has a second guiding slope 3421 corresponding to the first guiding slope 32225. With the above arrangement, when the drawer body 21 moves into the interior of the box body 11, with the cooperation of the first guiding slope 32225 and the second guiding slope 3421, the locking hook 32224 will not hinder the locking portion 342 from moving into the interior of the box body 11. When the drawer body 21 needs to be moved into the interior of the box body 11, as shown in FIG. Figure 6 to Figure 7As shown, the drawer body 21 is manually pushed to the right along the push-pull direction. When the first guide bevel 32225 contacts the second guide bevel 3421, the first guide bevel 32225 slides relatively along the second guide bevel 3421, so that the first rod portion 32221 rotates clockwise with the rotating portion 32223 as the rotation center, thereby preventing the lock hook 32224 from hindering the lock portion 342 from moving into the interior of the box body 11; when the first guide bevel 32225 is no longer in contact with the second guide bevel 3421, the restoring force of the reset spring 323 pushes the second rod portion 32222 upward to make the first rod portion 32221 rotate counterclockwise with the rotating portion 32223 as the rotation center, and finally makes the lock hook 32224 engage with the lock portion 342.

[0042] In some specific embodiments, the locking mechanism 322 also includes a matching portion 343, which is fixedly connected to the second connecting member 34 or formed on the second connecting member 34, and the other end of the elastic member 321 is fixedly connected to the matching portion 343 or is correspondingly arranged to the matching portion 343.

[0043] In some specific embodiments, the locking portion 342 and the matching portion 343 are integrally formed.

[0044] In some specific embodiments, Figure 5 As shown, the back wall of the box body 11 is provided with a through hole 111, and the telescopic device 3221 is provided on the outside of the back wall. The telescopic end of the telescopic device 3221 passes through the through hole 111 to push the second rod 32222. Through the above arrangement, the telescopic device 3221 is located outside the box body 11, thereby avoiding the telescopic device 3221 occupying the internal space of the box body 11, thereby increasing the storage space inside the box body 11 and improving the space utilization rate inside the box body 11. If it is necessary to transform the above-mentioned heating and cooling box into a manual opening and closing type, such as Figure 1 As shown, the through hole 111 is detachably installed with a blocking member 112. For the specific arrangement of the blocking member 112, refer to the above-mentioned electric opening and closing type heating and cooling box, which will not be repeated here.

[0045] In some specific embodiments, Figure 5 As shown, the connecting assembly further includes a bracket 35, and the telescopic device 3221 is arranged on the outer side of the back wall by means of the bracket 35. Figure 5 As shown, the bracket 35 is a plate structure, and the bracket 35 can also be a frame structure or a grid structure or other structures that can support the telescopic device 3221.

[0046] For example, when the opening and closing mode of the vehicle-mounted refrigerator or heater needs to be changed from electric opening and manual closing to electric opening and closing: first, the first connecting member 33 and the second connecting member 34 are removed from the box body 11 and the drawer body 21 respectively, so as to remove the connecting assembly with the second motion mechanism 32 from the vehicle-mounted refrigerator or heater; then, the connecting assembly with the first motion mechanism 31 is installed on the vehicle-mounted refrigerator or heater through the first connecting member 33 and the second connecting member 34, thereby completing the modification of the opening and closing mode of the vehicle-mounted refrigerator or heater.

[0047] The utility model can realize modular installation of the opening and closing hardware structure with the help of the first connecting member 33 and the second connecting member 34. When the assembled cold and warm box needs to be upgraded or converted into a cold and warm box with another opening and closing method according to user needs, it is only necessary to remove the connecting component as a whole and replace it with a connecting component with another opening and closing method. The connection method between the connecting component and the box body 11 and the drawer body 21 can be universal, which can greatly reduce the difficulty of disassembly and assembly, and at the same time improve the utilization rate of components such as the box body and drawers, so that the modification difficulty and modification cost of the vehicle-mounted cold and warm box are greatly reduced.

[0048] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
