Description

Technical Field

[0001] The present application relates to the technical field of outdoor travel equipment, and in particular to a suitcase with a solar charging function. Background Art

[0002] Suitcases are one of the essential equipment for people to travel outdoors. Whether people are going out for fun or traveling outdoors, they often need to use electronic devices such as mobile phones, cameras and notebooks. The energy of these electronic devices mostly comes from their built-in lithium batteries. In order to ensure the normal use of these electronic devices outdoors, people usually carry mobile power supplies to replenish the power of these electronic devices in time. The power stored in the mobile power supply is also limited. When the energy of the mobile power supply is exhausted and there is still no place to charge in time, the electronic devices will still face the problem of not being able to work normally due to lack of power. Therefore, some people will also choose to carry some solar panels for additional power supply, but when the area of ​​the solar panels carried is large, the large area of ​​solar panels will take up a lot of space and it is not convenient to carry and store; if for the convenience of storage, a smaller area of ​​solar panels is carried, there will be a problem of low power generation efficiency when using it.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0033] like Figure 1-Figure 7As shown, a suitcase with solar charging function disclosed in the present application comprises a suitcase body 1, a storage basket 2 is fixedly installed on the upper shell of the suitcase body 1, a protective cover 3 is hinged on the upper side of the storage basket 2, and the protective cover 3 can be freely opened and closed on the storage basket 2; a plurality of fan-shaped solar power generation panels 4 are arranged in sequence along the vertical direction in the storage basket 2, and a through mounting hole 5 is provided on one end of the solar power generation panel 4 close to the center of the circle; the mounting holes 5 on the plurality of solar power generation panels 4 are sleeved on the same telescopic sleeve 6; except that the lowest solar power generation panel 4 is fixedly connected to the telescopic sleeve 6, the remaining solar power generation panels 4 are rotatably connected to the telescopic sleeve 6; a guide column 7 is coaxially arranged in the telescopic sleeve 6, and the guide column 7 is slidably connected to the telescopic sleeve 6 along the vertical direction; an energy storage unit 8 is arranged in the suitcase body 1, and the energy storage unit 8 can store the electric energy converted by the plurality of solar power generation panels 4.

[0034] In the above embodiment, the box body 1 and the storage basket 2 of the present application are integrally formed, and the storage basket 2 is arranged outside the box body 1, so that when storing multiple solar panels 4, it will not occupy too much space inside the box body 1. The protective cover 3 above the storage basket 2 can be opened and closed freely, which is convenient for users to take and put the solar panels 4.

[0035] Multiple fan-shaped solar panels 4 are sleeved on the telescopic sleeve 6 through the mounting holes 5 at the small ends thereof, the lowest solar panel 4 is fixedly connected to the telescopic sleeve 6, and the remaining solar panels 4 are rotatably connected to the telescopic sleeve 6, and the axis of rotation is colinear with the axis of the telescopic sleeve 6. When the user needs to charge outdoors, the protective cover 3 on the storage basket 2 can be opened first, and then the telescopic sleeve 6 and the multiple solar panels 4 can be lifted upward from the storage basket 2 along the guide column 7, and the lowest solar panel 4 can be used as the basis, and the remaining multiple solar panels 4 can be unfolded around the telescopic sleeve 6 in sequence, so that the multiple solar panels 4 are surrounded in a circle around the telescopic sleeve 6. Since the solar panels 4 are fan-shaped, the top view of them when they are surrounded together is similar to the shape of a flower, and the multiple solar panels 4 can be exposed to sunlight at the same time, which effectively improves the solar energy receiving area and the power generation efficiency compared to a single solar panel 4, and the generated electricity can be stored in the energy storage unit 8 for users to use at any time.

[0036] like Figure 7As shown, when the user needs to move forward with the suitcase 1, the rotated multiple solar panels 4 can be rotated in reverse around the telescopic sleeve 6 to the initial position in turn until the multiple solar panels 4 are stacked together again, and then the multiple solar panels 4 and the telescopic sleeve 6 are put back into the storage basket 2 by using the guiding effect of the guide column 7 on the telescopic sleeve 6, and then the protective cover 3 is buckled. The space occupied by the multiple solar panels 4 folded together in the horizontal direction is significantly reduced, and it is convenient to carry after being stored in the storage basket 2. Moreover, after the multiple solar panels 4 are loaded with the storage basket 2 and the protective cover 3, the appearance of the suitcase has better integrity and aesthetics.

[0037] Furthermore, if Figure 1-Figure 4 As shown, except for the top solar panel 4, the upper sides of the remaining solar panels 4 are all provided with an arc-shaped guide slot 9; except for the bottom solar panel 4, the lower sides of the remaining solar panels 4 are all fixedly connected with a limit rod 10, and the limit rods 10 under these solar panels 4 are respectively movably inserted into the corresponding arc-shaped guide slots 9 above the solar panels 4 under them;

[0038] The curvature of the arc-shaped guide chute 9 is such that when the multiple solar panels 4 are deployed, the multiple arc-shaped guide chute 9 can form a circle;

[0039] The arc length of the arc guide groove 9 does not meet the requirement that when multiple solar panels 4 are stacked together, multiple limit rods 10 are all located at one end of their respective corresponding arc guide grooves 9; when multiple solar panels 4 are evenly unfolded along the circumferential direction, multiple limit rods 10 are all located at the other end of their respective corresponding arc guide grooves 9.

[0040] In the above embodiment, multiple solar panels 4 are arranged in the above manner. When the sun rises above, after the user lifts the multiple solar panels 4 together with the telescopic sleeve 6 out of the storage basket 2 along the guide column 7, the user only needs to rotate the top solar panel 4. Except for the bottom solar panel 4, the remaining solar panels 4 will follow the top solar panel 4 from top to bottom and unfold around the telescopic sleeve 6 in sequence until they form a circle on the outside of the telescopic sleeve 6, which can effectively improve the unfolding efficiency of the multiple solar panels 4.

[0041] When multiple solar panels 4 are unfolded, take the top solar panel 4 as an example. At the beginning, the limit rod 10 below the solar panel 4 is located at one end of the arc-shaped guide slot 9 on the solar panel 4 below it. During the rotation process, the limit rod 10 will slide along the arc-shaped guide slot 9 until it reaches the other end of the arc-shaped guide slot 9. The top solar panel 4 will use the end of the arc-shaped guide slot 9 to limit the limit rod 10 below it. The limit rod 10 begins to generate thrust on the adjacent solar panel 4 below it, thereby driving the solar panel 4 below it to rotate with the top solar panel 4. Similarly, in the second solar panel 4 ( The second solar panel 4 of the present application refers to the second solar panel 4 counted from the top to the bottom, and the other solar panels 4 are also named in this way. After the limiting rod 10 below moves from one end of the arc-shaped guide slot 9 on the third solar panel 4 to the other end, it begins to generate driving force for the fourth solar panel 4, and begins to unfold with the fourth solar panel 4. The unfolding principle of the other solar panels 4 is the same, until the penultimate solar panel 4 is unfolded, and the bottom solar panel 4 fixedly connected to the telescopic sleeve 6 forms a limit for them. At this time, multiple solar panels 4 are just evenly surrounded by a circle around the telescopic sleeve 6 to form a flower-like shape. Similarly, when it is necessary to stack multiple solar panels 4 together later, the user rotates the top solar panel 4 in the opposite direction until its projection on the horizontal plane coincides with the bottom solar panel 4, and the folding work of multiple solar panels 4 can be completed, and the operation is also convenient and quick.

[0042] Furthermore, if Figure 5 and Figure 8 As shown, a limiting unit 11 is provided at one end of the storage basket 2 close to the guide column 7. When the lowermost solar panel 4 moves upward to the upper end of the storage basket 2 along with the telescopic sleeve 6, the limiting unit 11 can automatically fix the position of the telescopic sleeve 6.

[0043] In the above embodiments, when the telescopic sleeve 6 and the plurality of solar panels 4 move upward along the guide column 7 until the lowest solar panel 4 reaches the upper port of the storage basket 2, the remaining solar panels 4 will not be hindered by the upper port of the storage basket 2 when rotating. At this time, the limiting unit 11 of the present application can automatically clamp the telescopic sleeve 6 and the lowest solar panel 4, so that after the user lets go, the plurality of solar panels 4 and the telescopic sleeve 6 can be fixed in this position, so that the user can continue to unfold them and use the plurality of solar panels 4 to generate electricity.

[0044] Furthermore, if Figure 5 and Figure 6As shown, the limiting unit 11 includes a wedge-shaped support block 111, and the inclined surface of the wedge-shaped support block 111 is located at the lower side and faces the guide column 7;

[0045] The end of the wedge-shaped support block 111 away from the guide column 7 is fixedly connected to one end of the sliding rod 112, and the end of the sliding rod 112 away from the wedge-shaped support block 111 passes through the side wall and thickened plate 113 of the storage basket 2 on the same side in sequence and is fixedly connected to the connecting block 114. The connecting block 114 is hinged with a first handle 115 on the side away from the storage basket 2. The sliding rod 112 is slidably connected to the side wall and thickened plate 113 of the storage basket 2 passed through, and the thickened plate 113 is fixedly connected to the storage basket 2; wherein the sliding rod 112 can be one or more, for example, can be two, that is, the end of the wedge-shaped support block 111 away from the guide column 7 is fixedly connected to the same end of the two sliding rods 112, and the other ends of the two sliding rods 112 are fixedly connected to the connecting block 114.

[0046] A spring 116 is sleeved on the portion of the sliding rod 112 between the wedge-shaped support block 111 and the inner wall of the storage basket 2 , and two ends of the spring 116 are fixedly connected to the wedge-shaped support block 111 and the inner wall of the storage basket 2 , respectively.

[0047] In the above embodiment, when the user pulls up the multiple stacked solar panels 4 and the telescopic sleeve 6 along the guide column 7, the small end of the top solar panel 4 will first contact the inclined surface of the wedge-shaped support block 111, and then squeeze the wedge-shaped support block 111, and the sliding rod 112 connected to the wedge-shaped support block 111 is slidably connected to the storage basket 2. Therefore, after the wedge-shaped support block 11 is squeezed, it will move toward the outside of the storage basket 2 along the axial direction of the sliding rod 112 under the limitation of the sliding rod 112 by the storage basket 2. During the movement, the distance between the wedge-shaped support block 111 and the inner wall of the storage basket 2 will gradually decrease, and the spring 116 will also be squeezed and have a certain elastic force. Since the multiple solar panels 4 are stacked on each other, the small ends of the remaining solar panels 4 will continue to squeeze the wedge-shaped support block 111 during the upward movement, so that the spring 116 continues to remain in a compressed state. After the lowest solar panel 4 reaches the upper port of the storage basket 2, it continues to move upward to pass over the wedge-shaped support block 111. At this time, the end of the wedge-shaped support block 111 close to the guide column 7 will lose its restriction and quickly reach the bottom of the lowest solar panel 4 under the action of the elastic force of the spring 116. At this time, after the user lets go, the lowest solar panel 4 fixedly connected to the telescopic sleeve 6 will fall on the wedge-shaped support block 111, so that the wedge-shaped support block 111 can limit the multiple solar panels 4 and the telescopic sleeve 6 to prevent them from falling back into the storage basket 2. The thickened plate 113 provided on the outside of the storage basket 2 can increase its contact area with the sliding rod 112, thereby providing a stable supporting force for the sliding rod 112, so that the sliding rod 112 and the wedge-shaped support block 111 can stably support the multiple solar panels 4 and the telescopic sleeve 6.

[0048] When the user needs to put multiple solar panels 4 back into the storage basket 2, the first handle 115 can be used to pull the connecting block 114 outward. Since the connecting block 114 is fixedly connected to the sliding rod 112, when the user pulls the first handle 115, the sliding rod 112 will simultaneously move the wedge-shaped support block 111 outward. There can be two sliding rods 112, so that the movement process of the wedge-shaped support block 111 will be smoother. When the wedge-shaped support block 111 is no longer in contact with the lowest solar panel 4, the multiple solar panels 4 and the telescopic sleeve 6 can be put back into the storage basket 2 along the guide column 7, and the operation is simple and convenient.

[0049] Furthermore, if Figure 1 , Figure 2 and Figure 5As shown, an annular mounting seat 12 is provided above the mounting hole 5 of the top solar panel 4, and the lower side of the annular mounting seat 12 is fixedly connected to the top solar panel 4; and the annular mounting seat 12 is movably sleeved on the telescopic sleeve 6, and the annular mounting seat 12 is hinged with a second handle 13 that can swing up and down toward the large end of the solar panel 4; the outer contour of the annular mounting seat 12 is similar to the outer contour of the small end of the solar panel 4.

[0050] In the above embodiments, the annular mounting seat 12 of the present application can only rotate along its axis outside the telescopic sleeve 6, and will not slide along the vertical direction of the telescopic sleeve 6, so that when the user pulls the annular mounting seat 12 upward through the second handle 13, the annular mounting seat 12 can move with the telescopic sleeve 6, so that it is convenient for the user to quickly lift the telescopic sleeve 6 and multiple solar panels 4 out of the storage basket 2 through the second handle 13 on the annular mounting seat 12. The lower end of the annular mounting seat 12 is fixedly connected to the top solar panel 4, so that the user can drive the top solar panel 4 to unfold around the telescopic sleeve 6 with other solar panels 4 through the second handle 13. The second handle 13 is arranged on the side of the annular mounting seat 12 close to the big end of the solar panel 4, so that when multiple solar panels 4 are stored in the storage basket 2, the second handle 13 can be prevented from being stuck at the upper end of the storage basket 2. The outer contour of the annular mounting seat 12 is similar to the outer contour of the small end of the solar panel 4, so that when multiple solar panels 4 are placed in the storage basket 2, the wedge-shaped support block 111 can transition from the top solar panel 4 to the annular mounting seat 12 more smoothly.

[0051] Furthermore, if Figure 5 and Figure 8 As shown, a limiting rubber pad 14 is embedded inside the storage basket 2, and an embedded groove 15 is provided on the limiting rubber pad 14. The shape of the embedded groove 15 on the limiting rubber pad 14 is similar to the overall external contour of the solar panel 4, and the depth of the embedded groove 15 on the limiting rubber pad 14 is equal to the sum of the thicknesses of multiple solar panels 4.

[0052] In the above embodiment, the embedded groove 15 provided inside the limiting rubber pad 14 in the storage basket 2 is close to the outer contour of the solar panel 4, and the depth is equal to the sum of the thicknesses of the multiple solar panels 4. In this way, when the user puts multiple solar panels 4 into the storage basket 2, they can be exactly embedded in the limiting rubber pad 14, so that the limiting rubber pad 14 can not only protect the multiple solar panels 4, but also prevent the multiple solar panels 4 from shaking in the storage basket 2 when the box 1 is moved. A rubber pad can also be provided on the inner side of the protective cover 3. When the protective cover 3 is covered on the storage basket 2, the rubber pad on the protective cover 3 can limit and protect the multiple solar panels 4 from above.

[0053] Furthermore, if Figure 1 and Figure 5 As shown, the energy storage unit 8 includes a battery shell 81 arranged inside the upper shell of the box body 1, and an energy storage battery 82 is arranged in the battery shell 81, and the energy storage battery 82 is electrically connected to the solar power generation panel 4; a charging port 83 is arranged on the top of the box body 1, and the charging port 83 is electrically connected to the energy storage battery 82.

[0054] In the above embodiments, the electric energy generated by the multiple solar panels 4 during use can be stored in the energy storage battery 82, and the electric energy in the energy storage battery 82 can be output to the outside through the charging port 83 on the outside of the box 1, so that the user can replenish the electric energy of the electronic devices they carry.

[0055] The energy storage battery of the present application is specifically an integrated battery similar to the outdoor power supply with light charging function in the prior art. This type of integrated battery with light charging function can be directly connected to the solar panel 4 through a connecting line, so as to store the electric energy generated by the solar panel 4. This type of integrated battery is a prior art, such as the commercially available Dianxiaoer outdoor power supply, so its specific principles and details are not elaborated here.

[0056] Furthermore, if Figure 7 As shown, after the protective cover 3 is covered on the storage basket 2, the free end of the protective cover 3 can be fixed to the storage basket 2 via the luggage buckle 16.

[0057] In the above embodiments, the free end of the protective cover 3 is connected to the storage basket 2 via a luggage buckle 16, so that it is very convenient for the user to open and close the storage basket 2. Since the luggage buckle 16 is a mature existing technology, it is sufficient to directly purchase luggage buckles 16 of suitable specifications during the production and assembly of the suitcases of the present application, which can effectively improve the production efficiency of the suitcases to a certain extent.

[0058] The implementation principle of this embodiment is as follows: when the power of the energy storage battery 82 is low outdoors, the user can lay down the box body 1 so that the upper shell with the storage basket 2 is facing upward. Then, unfasten the bag buckle 16 between the protective cover 3 and the storage basket 2, and pull the second handle 13 upward by hand. The second handle 13 can be moved vertically upward along the guide column 7 together with the multiple solar panels 4 through the telescopic sleeve 6. When the lowest solar panel 4 reaches the top of the wedge-shaped support block 111, the wedge-shaped support block 111 will move in the direction of the guide column 7 of the action box of the spring 116. After the wedge-shaped support block 111 reaches the bottom of the lowest solar panel 4, it can limit it. At this time, the user stops applying a vertical upward force to the second handle 13, and instead drives the top solar panel 4 to rotate around the connecting sleeve through the second handle 13. Except for the lowest solar panel 4, the remaining solar panels 4 will be driven by the second handle 13 to expand and form a circle along the circumference of the connecting sleeve. At this time, the multiple solar panels 4 can reach the maximum state of receiving sunlight, and the electrical energy generated after receiving the light will be stored in the energy storage battery 82.

[0059] When the user needs to drag the box 1 when charging or needs to move, the user first uses the second handle 13 to drag the top solar panel 4 to reset. In this process, the other solar panels 4 except the bottom solar panel 4 will reset together. When all solar panels 4 are stacked together again, the user pulls the first handle 115 by hand, and drives the wedge-shaped support block 111 away from the bottom solar panel 4 through the connecting block 114 and the sliding rod 112. At this time, the wedge-shaped support block 111 will remove the support effect on the bottom solar panel 4, and the user can press the stacked solar panels 4 and telescopic sleeve 6 back into the storage basket 2. Then, cover the protective cover 3 and use the bag buckle 16 to fix the remaining storage baskets 2 together again.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
