[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This utility model discloses a solar-heated tail box, referenced... Figure 1 As shown, the solar-heated tailgate includes a housing 100, a photovoltaic module 200, and a heating element 300. The housing 100 includes a main body 110 and a cover 120, with the cover 120 fastened to the main body 110. The photovoltaic module 200 includes a base 210 and photovoltaic units 220. The base 210 is rotatably mounted on the cover 120, and the photovoltaic units 220 are angle-adjustably mounted on the base 210. The heating element 300 is mounted on the main body 110 to heat the internal space of the housing 100 and is electrically connected to the photovoltaic units 220. It is understood that because the heating element 300 is mounted on the main body 110 and used to heat the internal space of the housing 100, and because the heating element 300 is powered by the photovoltaic module 200 rather than the vehicle's power supply, the heating power of the heating element 300 can be set to a larger value, improving the heating effect of the solar-heated tailgate. Since the photovoltaic module 200 includes a base 210 and a photovoltaic unit 220, the base 210 is rotatably mounted on the cover 120, and the photovoltaic unit 220 is mounted on the base 210 at an adjustable angle, in actual use, the photovoltaic unit 220 can be adjusted according to the position of the sun, thereby improving the utilization rate of solar energy and the power generation efficiency and energy storage efficiency of the photovoltaic module 200.

[0033] refer to Figure 1 and Figure 2As shown, the photovoltaic unit 220 includes a photovoltaic panel 221 and an energy storage output module 222. The energy storage output module 222 is equipped with a light detection unit and an electrical output unit. The solar heating tail box also includes a rotation drive assembly 400 and a swing drive assembly 500. The rotation drive assembly 400 is installed on the cover 120 and is used to drive the base 210 to rotate. The swing drive assembly 500 is installed on the base 210 and is used to drive the photovoltaic unit 220 to swing. The electrical output unit is electrically connected to the rotation drive assembly 400 and the swing drive assembly 500. It is understandable that, compared to manually adjusting the photovoltaic unit 220, in this embodiment, the angle of the photovoltaic panel 221 is automatically adjusted by adding a rotation drive component 400 and a swing drive component 500. During actual operation, the light detection unit can sense the light intensity from different directions. When the sun's position changes, the light detection unit detects the difference in light intensity and converts this difference into an electrical signal, which is then sent to the rotation drive component 400 and the swing drive component 500 to adjust the angle of the photovoltaic panel 221. The photoelectric conversion efficiency of the automatically tracking photovoltaic panel 221 can be increased by 40% compared to the previous method. Optionally, the light detection unit is a photoelectric sensor. Of course, in this embodiment of the invention, the light detection unit can also be selected with other structures according to actual needs. The specific structure of the power output unit is prior art, and there is no need to limit the structure of the power output unit here.

[0034] It should be noted that a touch screen can be installed on the cover 120 or the box body 110, or a wireless connection unit can be built into the energy storage output module 222 to realize intelligent mobile terminal app control, meet the user's needs for heating or keeping warm the items in the trunk in different scenarios, improve the convenience of operation and interactive experience. The energy storage output module 222 is powered entirely by the photovoltaic panel 221, which reduces the dependence on the vehicle's own power system and improves energy utilization efficiency.

[0035] refer to Figure 3 As shown, the rotary drive assembly 400 includes an electric drive source 410, a worm gear 420, and a worm wheel 430. The electric drive source 410 is mounted on the inner wall of the cover 120 and is electrically connected to the photovoltaic unit 220. The worm gear 420 is connected to the output shaft of the electric drive source 410. The worm wheel 430 is driven by the worm gear 420 and is fixedly connected to the base 210. It can be understood that during actual adjustment, the electric drive source 410 starts upon receiving an electrical signal, driving the worm gear 420 to rotate. The worm wheel 430 can then rotate under the drive of the worm gear 420 to achieve rotational adjustment of the base 210. Of course, in other embodiments of this invention, the rotary drive assembly 400 can also be a rotary motor or other structures mounted on the base 210.

[0036] refer to Figure 1 and Figure 4As shown, one end of the photovoltaic module 200 is rotatably connected to the cover 120; the swing drive assembly 500 includes an electric push rod, one end of which is rotatably connected to the cover 120, and the other end is rotatably connected to the photovoltaic unit 220, and the electric push rod is electrically connected to the photovoltaic unit 220. It can be understood that during actual operation, when the electric push rod receives an electrical signal, it initiates the swinging motion of the photovoltaic unit 220 to adjust its angle.

[0037] Optional, see reference Figure 1 As shown, the cover 120 is provided with a first latching portion 121 and a second latching portion 122 spaced apart; the photovoltaic unit 220 is provided with a mounting base 2232, and a first rotating shaft 600 passes through the mounting base 2232, and the first rotating shaft 600 is rotatably installed in the first latching portion 121; one end of the electric push rod is provided with a second rotating shaft 700, and the second rotating shaft 700 is rotatably installed in the second latching portion 122. It can be understood that the photovoltaic unit 220 is rotatably connected to the first latching portion 121 through the first rotating shaft 600, which facilitates the swing adjustment of the angle and also facilitates installation and disassembly, thereby facilitating the maintenance of the photovoltaic unit 220.

[0038] It should be further noted that in other embodiments of this utility model, the photovoltaic unit 220 is supported on the chassis by a rotatable support rod. During actual operation, the angle of the photovoltaic unit 220 can be adjusted by manually rotating the base 210 and the support rod. That is to say, in other embodiments of this utility model, the angle adjustment of the photovoltaic module 200 can be performed manually.

[0039] refer to Figure 4 As shown, the photovoltaic unit 220 also includes a photovoltaic box 223. The photovoltaic panel 221 and the energy storage output module 222 are both mounted in the photovoltaic box 223. A wiring hole 2231 is provided on the bottom wall of the photovoltaic box 223. The photovoltaic box 223 cooperates with the swing drive assembly 500. It can be understood that the photovoltaic box 223 serves as a support structure for the photovoltaic panel 221. One end of the electric push rod is rotatably connected to the photovoltaic box 223. This avoids setting a rotating structure on the photovoltaic panel 221, which is beneficial for increasing the advantageous power generation area of ​​the photovoltaic panel 221. Furthermore, the photovoltaic box 223 also protects the photovoltaic panel 221 and the energy storage output module 222.

[0040] refer to Figure 1As shown, the box body 110 has a protruding connecting part 111, the heating element 300 is a heating ring and is sleeved on the connecting part 111, and the cover 120 has a protruding edge 123 that cooperates with the connecting part 111. It can be understood that the heating element 300 is a heating ring and is connected to the connecting part 111. This not only facilitates heating the internal space of the box body 100, but also does not occupy the internal storage volume of the box body 100, ensuring the heating effect while improving the space utilization of the box body 100.

[0041] Optionally, the heating ring is bonded to the connecting part 111 using annular adhesive tape 800. This allows the heating ring to be easily and securely fixed to the connecting part 111.

[0042] Of course, it should be noted that in other embodiments of this utility model, the heating element 300 may also be a heating plate, which is disposed on the inner side wall of the box 100 or the cover 120.

[0043] refer to Figure 1 As shown, handles 124 are provided on the two opposite side walls of the cover 120. This facilitates the movement of the entire box 100 and also allows the user to easily open the cover 120 relative to the box body 110.

[0044] refer to Figure 1 As shown, the box body 110 is provided with a first pivot seat 112, and the cover 120 is provided with a second pivot seat 125. A third rotating shaft passes through the first pivot seat 112 and the second pivot seat 125 so that the cover 120 is rotatably connected to the box body 110. It can be understood that the box body 110 and the cover 120 are rotatably connected through the first pivot seat 112 and the second pivot seat 125. In actual opening, only the cover 120 needs to be rotated; there is no need to disassemble the entire cover 120 from the box body 110, which is convenient for the user.
