[0038] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to necessarily have a specific orientation, or to be constructed and operated in a specific orientation. In addition, in addition to indicating the orientation or positional relationship, the above-mentioned terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.
[0041] The present application provides a mailbox with a light source, such asFigure 1 , 2 As shown, the upper part of the mailbox is a storage cabinet 500, which is equipped with a delivery slot 300 and a door 100; the side wall of the mailbox is equipped with a light strip 200, which is on the same side of the mailbox as the door 100.
[0042] The mailbox has a door 100 and a light strip 200 on one side wall. The term "side wall" here does not include the top and bottom of the mailbox.
[0043] like Figure 3 , 4 As shown, the light strip 200 is parallel to the upper and lower edges of the door body 100. An inclined photovoltaic panel 210 is provided on the upward-facing area of the light strip 200. The photovoltaic panel 210 and the door body 100 have an angle α, where α is greater than 90°, meaning the photovoltaic panel 210 is inclined downwards. For example, α can be 100°, 110°, 120°, 145°, or 150°, etc.
[0044] like Figure 3 , 4 As shown in Figure 5, a light source plate 220 is provided in the area where the light strip 200 faces downward, so that the light strip 200 projects light downward. The photovoltaic panel 210 and the light source plate 220 protrude from the side wall of the mailbox, for example, from the outer wall of the door 100 and other areas of the side wall of the mailbox. The light source plate 220 is made of a light-transmitting material.
[0045] The light strip 200 is positioned in the middle of the mailbox, so that the light from the light strip is projected onto the lower part of the mailbox. It is worth emphasizing that the "middle" is not exactly the center in the height direction of the mailbox, but can be a position near the center.
[0046] Specifically, a combination cabinet 600 is installed at the bottom of the mailbox. A partition is installed between the combination cabinet 600 and the storage cabinet 500, so that the internal spaces of the combination cabinet 600 and the storage cabinet 500 are different. The light strip 200 is installed on the upper side of the combination cabinet 600, so that the light strip 200 projects light onto the outer wall of the combination cabinet 600.
[0047] In this way, the light strip 200 is installed on the mailbox in a manner equivalent to a "wall washer light". The photovoltaic panel 210 and the light source panel 220 in the light strip 200 are highly integrated into the side wall of the mailbox. The light from the light strip 200 is projected downwards onto the surface of the cabinet 600, so that the surface of the cabinet 600 is covered with a soft light, making the mailbox more visually appealing. Users can also accurately locate the mailbox by the light covering the cabinet. The light will not shine directly into the user's eyes, and the user's comfort is greatly improved.
[0048] At the same time, the photovoltaic panel 210 can be effectively exposed to sunlight to generate electricity. Once water falls on the surface of the inclined photovoltaic panel 210, it will directly slide off due to the inclination of the photovoltaic panel 210, preventing the photovoltaic panel 210 from being damaged due to long-term water accumulation. The downward light source panel 220 is further protected by the photovoltaic panel 210, and raindrops will not directly hit the light source panel 220, prolonging the service life.
[0049] Preferably, as shown in Figure 3 The lamp strip 200 is embedded in the side wall of the mailbox, that is, the lamp strip 200 only partially protrudes from the side wall of the mailbox, further improving the aesthetics of the mailbox. Specifically, the side wall of the mailbox can be formed by combining some rectangular block-shaped components to form a concave-convex structure, so that the lamp strip 200 is embedded therein. It should be noted that on the basis of the above structure, the photovoltaic panel 210 and the light source panel 220 on the lamp strip 200 also completely protrude from the side wall of the mailbox.
[0050] Optionally, the lamp strip 200 is installed to the door body 100, or the lamp strip 200 is installed between the door body 100 and the combination cabinet. As another optional solution, the lamp strip 200 can also be directly installed on the combination cabinet 200.
[0051] Preferably, as shown in Figure 2 The lamp strip 200 is installed to the door body 100 and rotates with the door body 100 to produce various light effects. At the same time, if the size of the lamp strip 200 is small, the lamp strip 200 needs to work through external batteries or control panel elements, etc. At this time, if the lamp strip 200 is arranged on the door body 100, the above-mentioned elements can be arranged in the storage cabinet 500 corresponding to the door body. The lamp strip 200 and each element are electrically connected through the wires passing through the door body 100. The storage cabinet 500 can effectively protect the elements when closed, and further makes the appearance of the mailbox simple and beautiful. The design of the easily opened and closed door body 100 is also more convenient for users to maintain and repair the above-mentioned device.
[0052] Further, as shown in Figure 3 The lamp strip 200 is installed at a position close to the lower side hinge point of the door body 100, so that the lamp strip 100 can also block the gap between the lower side of the door body 100 and the cabinet body of the storage cabinet 500, preventing rainwater from seeping into the interior of the storage cabinet 500 from the gap, thereby wetting the mail.
[0053] Specifically, as shown in Figure 3 The light source panel 220 and the back plate of the lamp strip 200 have an included angle b of 80°≤b≤90°, for example, b is 90°, 80°, 85°, etc. The light source panel 220 can project light vertically downward or slightly inclined outward to illuminate a larger area where the mailbox is located. If it exceeds the above range, it will affect the "wall washing" effect of the light.
[0054] Specifically, the lamp strip 200 is provided with a mounting frame 230 made of metal, which is optionally made of aluminum or stainless steel, so as to increase the strength of the lamp strip 200. The light source plate 220 and the photovoltaic plate 210 are fixed in the mounting frame 230.
[0055] Since the photovoltaic plate 210 and the light source plate 220 have weak structural strength and are difficult to withstand collision, preferably, as shown in Figures 4-6 The mounting frame 230 is provided with a collision prevention plate 231 between the photovoltaic plate 210 and the light source plate 220, the collision prevention plate 231 is a plate structure and extends along the length direction of the lamp strip 200, so as to comprehensively protect the lamp strip 200 as a whole. The collision prevention plate 231 is part of the mounting frame 230, so as to avoid the problem that the lamp strip 200 may be damaged due to being subjected to collision from the front. If the collision prevention plate 231 is cancelled and the photovoltaic plate 210 is directly adjacent to the light source plate 220, the photovoltaic plate 210 and the light source plate 220 are easy to be damaged at the same time.
[0056] Optionally, the collision prevention plate 231 can be inclined or vertical.
[0057] Specifically, as shown in Figure 5 The inside of the lamp strip 200 is formed with a containing cavity 240, and a lamp body for emitting light is arranged in the containing cavity 240 close to the light source plate 220. The light emitted by the lamp body can be transmitted from the light source plate 220.
[0058] Optionally, a control board, a battery and a light sensing element are also arranged in the containing cavity 240. The light sensing element can make the lamp body automatically turn on when the mailbox is located in an environment with weak light or darkness. Optionally, other timing devices can also be integrated in the containing cavity 240, so as to make the lamp body turn on and off at a fixed time. Other circuit control forms will not be described herein.
[0059] As another optional solution, the control board, the battery and other elements can not be arranged in the containing cavity 240, and a mounting box can be additionally arranged in the mailbox, and the above-mentioned elements are arranged in the mounting box and connected with the lamp body and the photovoltaic plate in the lamp strip.
[0060] Since the structural strength of the lamp body is weak and the space in the containing cavity 240 is limited, other elements may interfere with and damage the lamp body, preferably, as shown in Figure 5 In the containing cavity 240, the collision prevention plate 231 is connected with a partition plate 250, and the partition plate 250 is located on the upper side of the light source plate 220, so as to cover the lamp body and protect the lamp body. Specifically, the partition plate 250 has a certain strength and can be integrally formed with the mounting frame 230.
[0061] Optionally, as shown in Figure 5As shown, the partition plate 250 is a folded plate, and its longitudinal section is L-shaped. One side of the partition plate 250 is connected to the anti-collision plate 231, and the other side of the partition plate 250 is connected to the bottom surface of the mounting frame 230. Exemplarily, the partition plate 250 can also be a straight plate or a curved plate, etc.
[0062] Specifically, as shown in the drawings, Figure 5 As shown, the partition plate 250 is formed with a mounting channel 260, and the lamp body is located in the mounting channel 260. The partition plate 250 can effectively support other elements in the containing cavity 240. The mounting channel 260 is through at both ends, and is used for passing the line of the lamp body.
[0063] Optionally, the mounting channel 260 can also be open at only one end, which is convenient for the user to plug in the lamp body.
[0064] As a specific solution, as shown in the drawings, Figure 5 The bottom of the lamp strip 200 is composed of the bottom surface of the mounting frame 230 and the light source plate 220.
[0065] In order to facilitate the user to maintain or replace the components installed on the lamp strip 200, as an optional solution, the lamp strip 200 is detachably connected with the door body 100. The back plate of the lamp strip 200 is formed with an opening, which is communicated with the inside of the storage cabinet 100, and is convenient for line connection. As another optional solution, the opening of the lamp strip 200 is directly closed by the side wall of the mailbox.
[0066] As a specific solution, as shown in the drawings, Figure 6 As shown, the mounting frame 230 at least includes a frame body 232, a top plate 233, a bottom plate 234 and two side plates 235. The frame body 232 can be integrally formed with the top plate 233 and the bottom plate 234. One side plate 235 or both side plates 235 are detachably connected with the frame body 232, for example, screw connection, etc. When the user needs to maintain the lamp strip 200, only the side plate 235 needs to be removed, and the components in the lamp strip 200 can be repaired, etc.
[0067] Preferably, in the limited volume of the lamp strip 200, the width of the photovoltaic plate 210 is greater than the width of the lamp strip 200. This design can make the electric energy generated by the photovoltaic plate 210 meet the continuous lighting demand of the lamp strip 200 in the case of low light.
[0068] Further, as shown in the drawings, Figure 2 As shown, the top of the mailbox is provided with a delivery port 300, and the mailbox is rotatably connected with a flip cover 400. The flip cover 400 covers the delivery port 300, and the lamp body 200 is arranged in the area outside the flip cover 400, so as to avoid the user trying to hold the lamp body 200 to open the flip cover, and causing safety hazards.
[0069] Specifically, the flip cover 400 may have a raised edge or handle that is easy for the user to grip, allowing the user to easily open or close the cover.
[0070] In some implementations, such as Figure 2 As shown, the upper part of the mailbox is a storage cabinet 500, the interior of which is connected to the delivery slot 300. The bottom edge of the door 100 is hinged to the storage cabinet 500 to close it. Specifically, the door 100 can be connected to the cabinet body of the storage cabinet 500 via a chain to control the opening degree of the storage cabinet 500.
[0071] The lower part of the mailbox is a combination cabinet 600. As an option, this combination cabinet can be equipped with doors, thus functioning as an outdoor storage locker. Alternatively, the combination cabinet 600 can be enclosed on all sides and top, raising the storage cabinet 500 so that users do not need to bend over to drop mail, while also controlling the depth of the mailbox so that letters at the bottom of the storage cabinet 500 are easily accessible to the user.
[0072] Optional, such as Figure 2 As shown, the light strip 200 is installed on the door 100 of the storage cabinet 500 and rotates with the door 100.
[0073] As an alternative, the light strip 200 is installed on the side wall of the combination cabinet 600, or the light strip 200 is installed between the storage cabinet 500 and the combination cabinet 600.
[0074] Preferred, such as Figure 3 As shown, a support portion 700 is provided on the lower side of the light strip 200. The support portion 700 is rectangular and extends along the length of the light strip 200. The top of the support portion 700 abuts against the light strip 200, providing a certain support for the light strip 200.
