[0056] Embodiment one

[0057] As Figures 1 to 17 shown, the utility model discloses a kind of box type storage electric vehicle sunshade rainproof device, it includes:

[0058] Storage box 1, access is provided on storage box 1;Storage box 1 is installed on the head or handlebar of electric vehicle;

[0059] Bottom plate 2, it is arranged in storage box 1, or bottom plate 2 is as the bottom wall of storage box 1;

[0060] Winding component 3, winding component 3 includes reel 31 being arranged on bottom plate 2 and shielding assembly 32 being wound on reel 31, reel 31 can be wound shielding assembly 32 in the inside of storage box 1 or be unfolded to the outside of storage box 1 when rotating;The first end of shielding assembly 32 is connected with reel 31, and the second end of shielding assembly 32 is provided with cross bar 33;

[0061] Support component 4 can be foldably stored in the inside of storage box 1, and can be unfolded to the outside of storage box 1 to support shielding assembly 32 through access;The first end of support component 4 is connected with bottom plate 2, and the second end of support component 4 away from bottom plate 2 is connected with cross bar 33;

[0062] Limiting component 10 is arranged on bottom plate 2, for limiting support component 4 when support component 4 is unfolded to target working state.Target working state refers to the maximum unfolding state of support component 4, or maximum degree or support component 4 moves to target position.

[0063] The storage box 1 in this embodiment can be made of high-strength plastic material or lightweight material, which has sufficient durability and pressure resistance. One side of the storage box 1 is provided with an access opening, which serves as an unfolding and storage channel for the shielding assembly 32 and the support component 4. The size of the access opening is reasonably designed, which can accommodate the unfolding of the shielding assembly 32 and facilitate the folding and stretching of the support component 4. The internal space of the storage box 1 is optimally designed, which can effectively accommodate the storage of the shielding assembly 32, the reel 31, and the support component 4, etc. devices, keeping the appearance of the electric vehicle clean and not occupying too much additional space.

[0064] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 10 and Figure 11 , the bottom plate 2 is arranged inside the storage box 1 and serves as the bottom wall of the entire device, supporting the shielding assembly 32, the reel 31, and the support component 4, etc. devices. The bottom plate 2 can be made of corrosion-resistant, wear-resistant lightweight material to ensure that it is not affected by environmental factors during long-term use.

[0065] As shown in Figures 2 to 6 , Figure 16 and Figure 17 , the winding component 3 is composed of the reel 31 and the shielding assembly 32 wound around the reel 31. The reel 31 is installed on the bottom plate 2 and can rotate smoothly through bearings or other rotating devices. When the user needs to unfold the shielding assembly 32, the user can manually pull the crossbar 33 outward to drive the reel 31 to rotate, allowing the shielding assembly 32 to unfold outside the storage box 1. When the user no longer needs to use it, the user can perform a recycling operation to rewind the shielding assembly 32 to the inside of the storage box 1. The first end of the shielding assembly 32 is connected to the reel 31, ensuring that the shielding assembly 32 can be evenly and securely unfolded and stored when the reel 31 rotates. The second end of the shielding assembly 32 is connected to the crossbar 33, which can be pulled by the user to drive the shielding assembly 32 to unfold towards the tail of the electric vehicle, and similarly, the crossbar 33 can be pulled by the user to drive the shielding assembly 32 to be recycled towards the storage box 1.

[0066] The support component 4 is designed in a folding manner, which can be stacked or stacked inside the storage box 1 when not in use, and unfolded through the access opening to support the shielding assembly 32 below. The first end of the support component 4 is fixedly connected to the bottom plate 2, which is connected by hinges or other foldable connection methods, allowing the support component 4 to be conveniently folded and stored. The second end of the support component 4 is connected to the crossbar 33 of the shielding assembly 32.

[0067] The beneficial technical effects of the technical scheme are that: by integrating the shielding assembly and the foldable supporting part in the storage box, the integrated storage and quick deployment function of the sun-shading and rain-shielding device is realized. The supporting part forms stable support with the bottom plate through the rotating connection structure, and the position of the supporting part can be automatically locked when it is deployed in combination with the limiting part 10, so as to ensure the structural stability of the shielding assembly in strong wind and rain weather. The design of the winding part reel enables the shielding cloth to be synchronously stretched and retracted with the horizontal rod, which not only ensures the flexible coverage of the sun-shading area, but also realizes convenient storage through automatic winding of the reel. The entire device adopts a box structure design, and is completely hidden in the storage box in a non-use state, effectively avoiding damage to the appearance integrity of the electric vehicle, and is particularly suitable for all-weather protection needs of the electric vehicle during temporary parking.

[0068] Embodiment Two

[0069] As shown in Figures 7 to 12 , the limiting part 10 includes: a limiting assembly 110 including a limiting sheet 111, a first rotating shaft 112 provided at the middle part of the limiting sheet 111, and a control end 113 provided at one side of the limiting sheet 111, the first rotating shaft 112 is connected with the bottom plate 2, the bottom plate 2 is provided with a through hole at the mounting position corresponding to the limiting sheet 111, the control end 113 extends to the outside of the bottom plate 2 through the through hole; a connecting hole 114 is provided on the control end 113; a spring assembly 120 including a mounting seat 121 and a spring element 122, the spring element 122 is installed in the mounting seat 121, the mounting seat 121 is provided outside the bottom plate 2, and the top end of the spring abuts against the bottom part of the limiting sheet 111 between the first rotating shaft 112 and the control end 113.

[0070] In some embodiments, the box-stored electric vehicle sun-shading and rain-shielding device can further include: an operating rod 130, the operating rod 130 including a pressing segment 131, a middle straight segment 132, and a connecting segment 133, the middle straight segment 132 being connected between the pressing segment 131 and the connecting segment 133; an operating hole is provided on the side wall of the storage box 1, and a through hole is provided on the bottom plate 2 of the storage box 1, the pressing segment 131 extends out of the operating hole and can move up and down within the movement range defined by the operating hole; the middle straight segment 132 extends out of the through hole, and the connecting segment 133 is connected with the connecting hole 114.

[0071] Specifically, the limiting sheet 111 is an arc-shaped plate or a plastic plate, and the middle part is hinged to the bottom plate 2 through the first rotating shaft 112, so that the limiting sheet 111 can rotate within a certain angle range about the first rotating shaft 112. The first rotating shaft 112 is fixed on the bottom plate 2 through bearing or shaft hole cooperation, and as Figure 8 and Figure 9The axis direction of the first rotating shaft 112 is parallel to the axis of the second rotating shaft 63. The limiting sheet 111 is divided by the first rotating shaft 112 into a first part on one side of the first rotating shaft 112 and a second part on the other side, which correspond to the left side region and the right side region respectively. Figure 9 The bottom of the first part of the limiting sheet 111 extends downward to form a control end 113, which penetrates a through hole in the bottom plate 2 and extends to the outside of the bottom plate 2. The control end 113 is provided with a connecting hole 114 for linkage with an external operating rod 130. The side wall of the first part of the limiting sheet 111 is a limiting wall 115, the end of which can abut against the rotating arm of the support component 4, thereby limiting the unfolding angle of the support component 4.

[0072] Specifically, the spring assembly 120 includes a mounting seat 121 and a spring element 122. The mounting seat 121 is fixed to the outer side surface of the bottom plate 2, i.e., the side away from the inside of the storage box. The spring element 122 is vertically installed in the inner cavity of the mounting seat 121. The top end of the spring element 122 elastically abuts against the bottom of the limiting sheet 111 in the region between the first rotating shaft 112 and the control end 113. When the limiting sheet 111 rotates around the first rotating shaft 112, the spring element 122 generates a reverse force by compression or release, forcing the limiting sheet 111 to always have a tendency to return to the initial position. The pre-tightening force of the spring element 122 can be adjusted by adjusting the compression amount of the spring element 122 in the mounting seat 121, thereby controlling the limiting strength of the limiting sheet 111 on the support component 4.

[0073] Specifically, the operating rod 130 is integrally formed by a pressing segment 131, an intermediate straight segment 132, and a connecting segment 133. The two ends of the intermediate straight segment 132 are connected with the pressing segment 131 and the connecting segment 133 respectively, forming a "Z" shape structure. A vertical operating hole is formed in the side wall of the storage box 1, and a through hole is formed in the bottom plate 2. The pressing segment 131 penetrates the operating hole and extends to the outside of the storage box 1. The user can drive the operating rod 130 to move along the vertical direction defined by the operating hole by pressing or pulling the pressing segment 131. The intermediate straight segment 132 penetrates the through hole in the bottom wall or the bottom plate 2, and the connecting segment 133 is fixedly connected with the connecting hole 114 in the control end 113 of the limiting sheet 111 outside the storage box 1 through a pin shaft or a threaded fastener. When the pressing segment 131 is pressed down, the operating rod 130 drives the limiting sheet 111 to rotate counterclockwise around the first rotating shaft 112, so that the limiting wall 115 is disengaged from the blocking of the support component 4, thereby realizing the unlocking and folding storage of the support component.

[0074] Specifically, referring to Figure 8 , Figure 9 and Figure 16In the process of unfolding the support component 4, when rotated to the target angle or target position, the second support sub-bar 52 in the bottom layer of the support bar element 5 in the first folding support bar assembly 42 and the second folding support bar assembly 43 is in contact or abuts against the limiting wall 115 of the limiting sheet 111, the limiting sheet 111 is kept stationary under the elastic force of the spring element 122, forming a rigid limit. At this time, the support component 4 is locked in the unfolded state. When folding is needed, the user presses the pressing section 131 of the operating rod 130, and through the transmission of the intermediate straight section 132 and the connecting section 133, forces the limiting sheet 111 to rotate around the first rotating shaft 112 and compresses the spring element 122, and the limiting wall 115 is disengaged from the support component 4, and the support component 4 can be freely rotated and reset to the storage box 1. After releasing the pressing section 131, the spring element 122 pushes the limiting sheet 111 back to position, preparing for the next limiting action. This embodiment realizes the bidirectional control of limiting and unlocking through mechanical linkage, and the operation is intuitive and highly reliable.

[0075] The beneficial technical effect of this embodiment is that through the elastic cooperation of the limiting sheet and the spring assembly and the linkage design of the operating rod, rigid locking and one-key quick unlocking of the support component in the unfolded state are realized. The user only needs to press the exposed operating rod to drive the limiting sheet to disengage from the support component, and the automatic spring resetting function simplifies the operation steps; the mechanical linkage limiting structure ensures wind pressure stability while avoiding the problem of accidental unlocking caused by accidental touch or vibration of the traditional limiting mechanism. In addition, the "Z" shaped layout of the operating rod cooperates with the hole position of the side wall and the bottom wall of the storage box, which not only ensures the reliability of the operation force transmission path, but also makes the overall structure compact, fully adapts to the box storage space, and meets the needs of efficient limiting and hidden control of the device.

[0076] Embodiment three

[0077] In some embodiments, as shown in Figures 3 to 6 The support component 4 comprises: a track 41 provided on the bottom plate 2 and extending along the width direction of the shielding assembly 32, both ends of the track 41 are provided with baffles; a first folding support bar assembly 42 and a second folding support bar assembly 43 are arranged along the width direction of the shielding assembly 32; the first folding support bar assembly 42 and the second folding support bar assembly 43 respectively comprise:

[0078] As shown in Figure 3 , Figures 15 to 17As shown, there are multiple support rod elements 5, each support rod element 5 including two support sub-rods, namely a first support sub-rod 51 and a second support sub-rod 52, which are rotatably connected at their midpoints; the two upper ends of the lower support rod element 5 in any two adjacent sets of support rod elements 5 are rotatably connected to the two lower ends of the upper support rod element 5; the lower end of the first support sub-rod 51 in the bottommost support rod element 5 is connected to the base plate 2, and the lower end of the second support sub-rod 52 in the bottommost support rod element 5 is restricted to slide in the track 41; the upper end of one support sub-rod in the topmost support rod element 5 is rotatably connected to the crossbar 33.

[0079] Specifically, the track 41 is mounted on the base plate 2 and extends along the width of the shielding assembly 32. The function of the track 41 is to provide a sliding and guiding path. The material of the track 41 can be a high-strength, wear-resistant plastic to ensure sufficient durability during frequent use.

[0080] The first folding support rod assembly 42 and the second folding support rod assembly 43 are spaced apart along the width direction of the shielding assembly 32, respectively located on both sides of the shielding assembly 32. Each support rod assembly consists of multiple cross-arranged support rod elements 5. Each support rod element 5 includes two support sub-rods, and the midpoints of the two support sub-rods are rotatably connected to form a support point. This design enables the support rod assembly to provide stronger stability when unfolded and to be effectively stored when folded.

[0081] like Figure 16 As shown, the midpoints of the two support sub-rods in each support rod element 5 are rotatably connected. The connection between any two adjacent support rod elements 5 is designed such that the lower end of the upper support rod element 5 is rotatably connected to the upper end of the lower support rod element 5. This cross-arrangement design allows each support rod element 5 to form a stable support frame when deployed, providing effective support force during the use of the shielding assembly 32 and preventing it from sagging or tilting. The cross structure of the support rod elements 5 enhances the stability of the entire support component 4, making it more adaptable to use in windy and rainy weather.

[0082] In the bottommost support rod element 5, the lower end of the first support sub-rod 51 is connected to the base plate 2, while the lower end of the second support sub-rod 52 is confined within the track 41, allowing it to slide only along the extension direction of the track 41. This design ensures that the support rod assembly can slide smoothly along the track 41 when unfolded and will not misalign or jam when folded. Furthermore, the sliding characteristics of the support rod element 5 also ensure that when support is not needed, the support component 4 can be folded and stored in its most compact position, without occupying extra space.

[0083] Figure 15and Figure 16 As shown in the drawings, in the support rod element 5 at the topmost layer, the upper end of one support sub-rod is rotationally connected with the cross rod 33. Through this design, when the user pulls or retracts the cross rod 33, the expansion and storage of the shielding assembly 32 and the support part 4 can be simultaneously driven, which is convenient for the user's use convenience.

[0084] The design of the support part 4 of the embodiment guiding and folding the support rod assembly through the track 41 not only makes the support part 4 have strong stability and wind resistance, but also optimizes the storage process. Through the cross design of the support rod element 5, the support force is effectively distributed, and the shielding assembly 32 can remain stable under different weather conditions. In addition, the folding design enables the support part 4 to be effectively stored in the storage box 1 when not in use, saving space and improving convenience.

[0085] Embodiment Four

[0086] In some embodiments, as shown in Figure 15 and Figure 16 The bottom plate 2 is provided with a first pivot connection part 6 and a second pivot connection part 7 on both sides in the length direction of the track 41, and the track 41 is arranged between the first pivot connection part 6 and the second pivot connection part 7;

[0087] The first pivot connection part 6 is connected with the lower end of the first support sub-rod 51 in one support rod element at the bottommost layer in the first folding support rod assembly 42;

[0088] The second pivot connection part 7 is connected with the lower end of the first support sub-rod 51 in one support rod element at the bottommost layer in the second folding support rod assembly 43.

[0089] In some embodiments, as shown in Figure 16 and Figure 17 The track 41 includes a first track wall 411 and a second track wall 412 arranged at intervals, and a recessed space 413 for the lower end of the second support sub-rod 52 in the two support rod elements at the bottommost layer is formed between the first track wall 411 and the second track wall 412;

[0090] The inner part of the opposite wall surfaces of the first track wall 411 and the second track wall 412 is respectively provided with a first groove 414 and a second groove 415 extending along the width direction of the shielding assembly 32;

[0091] The two support rod elements 5 at the bottommost layer slide in the first groove 414 and the second groove 415 through sliding elements. Specifically, the lower end of the second support sub-rod 52 in the two support rod elements at the bottommost layer is respectively vertically connected with a first sliding rod 8 and a second sliding rod 9; the first sliding rod 8 and the second sliding rod 9 can slide in the first groove 414 and the second groove 415.

[0092] In this embodiment, as shown in Figure 16 The first and second pivot joints 6 and 7 are provided on the base plate 2, respectively on the two sides of the track 41. The function of these pivot joints is to provide a rotating connection point for the support component 4. The support rod assembly is connected to the base plate 2 through the pivot joints, forming a support structure. The first pivot joint 6 is connected to the lower end of the first support sub-rod 51 of the bottom layer of support rod elements 5 in the first folding support rod assembly 42, and the second pivot joint 7 is connected to the lower end of the first support sub-rod 51 of the bottom layer of support rod elements 5 in the second folding support rod assembly 43. This pivot joint design allows the support component 4 to provide a strong support force when the shading assembly 32 is unfolded, and to be easily folded back for storage, saving space.

[0093] The track 41 in this embodiment is designed to include a first track wall 411 and a second track wall 412, forming a recessed space 413 between the two track walls for the lower end of the second support sub-rod 52 of the support rod element 5 to be inserted. Through this design, the second support sub-rod 52 of the support rod element 5 remains stable in the track 41, providing uniform support force when unfolded. The provision of track walls not only serves to position the support rod elements 5, but also ensures that the support rod elements 5 do not fall off or deviate when sliding.

[0094] In this embodiment, the first and second track walls 411 and 412 have first and second grooves 414 and 415 respectively formed on the opposite wall surfaces, extending in the width direction of the shading assembly 32. The design of these grooves allows the second support sub-rod 52 of the two bottom layer support rod elements 5 to slide accurately and stably support the shading assembly 32 when unfolded. The provision of the first and second grooves 414 and 415 further improves the stability and smoothness of operation of the support component 4, reduces the friction between the support component 4 and the track 41, and avoids the problem of unstable support due to excessive resistance during use.

[0095] The lower end of the second support sub-rod 52 of the two bottom layer support rod elements 5 is connected to a first sliding rod 8 and a second sliding rod 9 respectively, which can slide in the first and second grooves 414 and 415. The design of the sliding rods allows the support rod elements to slide smoothly in the track 41, providing better support force and flexibility. The material of the sliding rods can be selected from materials with low friction coefficient, such as stainless steel or plastic, to reduce wear and tear during sliding and improve the durability and service life of the entire device. The first and second sliding rods 8 and 9 can slide smoothly in the track 41, making the support rod elements more convenient and stable during unfolding and folding.

[0096] Embodiment Five

[0097] In some embodiments, as shown in Figure 3 and Figure 5 The shading assembly 32 includes a transparent film 321 and a sunshade tarpaulin 322, one end of the transparent film 321 is fixed on the winding component 3, and the sunshade tarpaulin 322 is connected to the rear end of the transparent film 321.

[0098] The winding shaft 31 can release the transparent film 321 and the sunshade tarpaulin 322 through the exit and entrance under the action of pulling force, and automatically wind the transparent film 321 and the sunshade tarpaulin 322 through the exit and entrance under the action of no external force. The exit and entrance are arranged on the top or side of the storage box 1.

[0099] In some embodiments, each support sub-bar is slightly curved, and the curved directions of each support sub-bar are the same. In this embodiment, the design of curved support sub-bars is beneficial to form an arc-shaped support structure after unfolding. Through this curved design, the support sub-bars can form a stable arc-shaped support surface when unfolded, effectively dispersing and absorbing external applied forces, enhancing the wind resistance and stability of the overall structure. In addition, the arc-shaped support structure can optimize the mechanical properties, improve the stability of the support component 4 during the use of the shading assembly 32, and prevent the shading assembly 32 from tilting or sagging. The curved shape can also improve the storage process, so that the device can be folded more compactly, saving space, and improving the overall convenience and aesthetics.

[0100] In some embodiments, the bottom of the storage box 1 is also provided with one or more connecting brackets for connecting with the head or handle of the electric vehicle.

[0101] In some embodiments, the first folding support bar assembly 42 and the second folding support bar assembly 43 each include 4 to 8 groups of cross-arranged support bar elements 5, preferably 6 groups of cross-arranged support bar elements 5. In this embodiment, the design of multiple cross-arranged support bar elements 5 can improve the stability and pressure resistance of the support structure. Through cross-arrangement, the support bar elements 5 can more evenly distribute external forces, enhancing the load-bearing capacity of the entire support system and preventing the support component 4 from tilting or deforming during use. In addition, the design of multiple support bar elements 5 allows the shading assembly 32 to provide more balanced and powerful support when unfolded, improving safety and reliability during use.

[0102] In some embodiments, the support component 4 is arranged closer to the rear direction of the electric vehicle relative to the winding component 3 in the storage state in the storage box 1.

[0103] Embodiment six

[0104] As shown in Figure 8 and Figure 15As shown, the first pivot joint 6 or the second pivot joint 7 respectively comprises a first support base 61 and a second support base 62 fixed on both sides of the installation base, the first support base 61 and the second support base 62 are provided with through holes for the second rotating shaft 63 to pass through, the second rotating shaft 63 passes through the through holes of the first support base 61 and the second support base 62 and is connected with the lower end of the first support sub-rod 51, allowing the first support sub-rod 51 to rotate around the second rotating shaft 63;

[0105] The second support base 62 is closer to the tail of the electric vehicle than the first support base 61, and the height of the second support base 62 is higher than that of the first support base 61.

[0106] As shown, Figure 7 The second track wall 412 is closer to the tail of the electric vehicle than the first track wall 411, and the height of the second track wall 412 is higher than that of the first track wall 411. The raised part of the second track wall 412 can additionally act as a limiting baffle for the support sub-rod, thus having a supporting effect, making the sun-shading and rain-shielding device more solid and firm, and reducing the shaking amplitude of the sun-shading and rain-shielding device in strong wind or high-speed riding.

[0107] Through the asymmetric arrangement of the first support base and the second support base and the differential height design of the track wall, the stress distribution and motion trajectory constraint of the support sub-rod are optimized. The second support base is offset to the high position on the tail side to form an inclined fulcrum, combined with the raised structure of the second track wall, the wind pressure resistance of the sun-shading and rain-shielding device under dynamic load is enhanced, effectively reducing the shaking in high-speed riding or strong wind environment; at the same time, the height difference design of the track wall strengthens the guiding constraint when the support sub-rod slides.

[0108] Embodiment seven

[0109] The lengths of the plurality of support rod elements 5 gradually decrease along the direction from the bottom layer to the top layer; or, among the plurality of support rod elements 5, the plurality of support rod elements 5 at the bottom layer have a first length, the plurality of support rod elements 5 at the middle layer have a second length, and the support rod element 5 at the top layer has a third length; the first length is greater than the second length, and the second length is greater than the third length; or, among the plurality of support rod elements 5, at least one support rod element 5 at the lower layer has a first length, and at least one support rod element 5 at the upper layer has a second length, and the first length is greater than the second length. The height of each sub-support rod is inconsistent, and the bottom is higher. The bottom is thicker and more solid. This is conducive to reducing the height of the overall support rod and making the volume smaller. In some embodiments, the height of the support rod sub-rod is divided into three grades, and the height or length decreases from the bottom to the top in the direction from the front of the vehicle to the tail of the vehicle.

[0110] The box-stored electric vehicle sun-shading and rain-shielding device comprises any one or more of the following: at least one through hole for drainage is arranged on the bottom plate 2; the front wall of the storage box 1 is arc-shaped and curved towards the tail of the electric vehicle; the area of the top of the storage box 1 is smaller than the area of the bottom plate 2 of the storage box 1; and the lower edge of the front wall is provided with a transparent water-shielding curtain.

[0111] The beneficial technical effect of the embodiment is that: by arranging the plurality of support rod elements 5 in a step-by-step layout with the length decreasing from the bottom layer to the top layer (or from the front to the rear direction), the bottom part uses longer, thicker and higher-strength support rods, forming a stable structure with a narrow top and a wide bottom, which reduces the height and volume of the overall support system, facilitates storage, and enhances the load-bearing capacity and wind pressure resistance through the high-strength sub-support rods at the bottom; the upper short rods reduce the overall weight and optimize the distribution of the center of gravity, and the layered and decreasing design forms a gradient stress when the support system is deployed, avoiding stress concentration and improving the structural stability and anti-deformation ability of the sun-shading and rain-shielding device in a dynamic environment.

[0112] Embodiment Eight

[0113] In combination with the above Figure 16 and Figure 17 , the embodiment provides a box-stored electric vehicle sun-shading and rain-shielding device, which comprises:

[0114] a storage box 1, wherein the storage box 1 is provided with an entrance;

[0115] a bottom plate 2, which is arranged in the storage box 1 or serves as the bottom wall of the storage box 1;

[0116] a winding component 3, which comprises a winding shaft 31 arranged on the bottom plate 2 and a transparent film 321 wound on the winding shaft 31, wherein the difference from the previous embodiments is that only the transparent film 321 is wound on the winding shaft 31, and the sun-shading and rain-shielding cloth 322 is no longer arranged on the winding shaft 31; the first end of the transparent film 321 is connected with the winding shaft 31, the second end of the transparent film 321 is connected with the first end of the sun-shading and rain-shielding cloth 322, and the second end of the sun-shading and rain-shielding cloth 322 is provided with a horizontal rod 33;

[0117] The support component 4 is foldably accommodated in the interior of the storage box 1 and can be unfolded to the outside of the storage box 1 through the entrance to support the shielding assembly 32, which includes a transparent film 321 and a sunshade rain cloth 322. The first end of the support component 4 is rotationally connected with the bottom plate 2, and the second end of the support component 4 away from the bottom plate 2 is connected with the horizontal rod 33. The sunshade rain cloth 322 is detachably arranged on the support component 4. The accommodation space for accommodating the sunshade rain cloth 322 in a stacked state is arranged between the reel 31 and the support component 4. The sunshade rain cloth 322 is connected to the surface of the support component 4, such as the outer surface of the upper end of the support rod element 5, through a detachable connector. Specifically, when the sunshade rain cloth 322 is accommodated in the storage box 1, the sunshade rain cloths 322 are sequentially stacked from bottom to top. The sunshade rain cloth 322 can be fixed to the surface of the support component 4 through a detachable buckle or a magic tape. In the snap connection mode, the male buckle is fixed on the corresponding plurality of rod members (support rod elements 5) of the support component 4, and the female buckle is sewn on the corresponding position of the sunshade rain cloth 322, and the detachable connection is achieved by pressing and buckling. In the waterproof magic tape connection mode, the hook surface (such as nylon hook surface) of the magic tape is pasted on the surface of the rod member of the support component 4, and the nap surface (such as polyester nap surface) of the magic tape is sewn on the corresponding position of the sunshade rain cloth 322, and the detachable connection is achieved by hook and nap adhesion. In the magnetic attraction buckle connection mode, the magnet sheet is pasted on the rod member of the support component, and the metal sheet is arranged on the corresponding position of the sunshade rain cloth, and the detachable connection is achieved by magnetic attraction of the magnet sheet and the metal sheet. In the hook ring buckle connection mode, the hook is fixed on the rod member of the support component 4, and the ring buckle cooperating with the hook is sewn on the corresponding position of the sunshade rain cloth, and the detachable connection is formed by hooking the hook into the ring buckle.

[0118] The limiting component 10 is arranged on the bottom plate 2 and is used for limiting the support component 4 when the support component 4 is unfolded to the target working state.

[0119] The advantage of the embodiment is that the reel 31 only winds the transparent film 321 and no longer winds the rain canopy cloth, i.e., the sunshade rain cloth 322, which is connected to the folding support rod of the scissors type, so that the volume of the product can be reduced and the film can be protected. The reel 31 is beneficial to protect the transparent film 321 and prevent the transparent film 321 from being abraded. The rain canopy cloth is connected to the support rod and is foldably accommodated in the space between the reel 31 and the support component 4 in the storage state.

[0120] As Figure 13 and Figure 14As shown, in some embodiments, the sunshade rain cover 322 is provided with a plurality of fixing assemblies 34 spaced along the length direction, each fixing assembly 34 comprising: a sleeve 341 provided at the middle of the sunshade rain cover 322 in the width direction, the sleeve 341 having openings at both axial ends; a rod sleeve 342 provided at both side edges of the sunshade rain cover 322 in the width direction, the rod sleeve 342 being closed at the outer end and having an opening at the inner end; and a connecting rod 343; the support component 4 comprises a first folding support rod assembly 42 and a second folding support rod assembly 43 spaced along the width direction of the shading assembly 32; the first folding support rod assembly 42 and the second folding support rod assembly 43 each comprise: a plurality of support rod elements 5, each support rod element 5 being formed into a scissor structure by two support sub-rods crossing through a middle hinge point, adjacent support rod elements 5 being connected in sequence through end hinges, and each support rod element 5 being provided with a pipe clamp 53 at the upper end; the plurality of pipe clamps 53 correspond one-to-one to the plurality of fixing assemblies 34; and each connecting rod 343 is inserted into the corresponding rod sleeve 342 after passing through the corresponding sleeve 341 and pipe clamp 53.

[0121] The design has the advantages that: through the modular combination of the sleeve 341, rod sleeve 342 and connecting rod 343, the sunshade rain cover 322 and the support rod element 5 are uniformly fixed at multiple points. The connecting rod 343 is inserted into the rod sleeve 342 on both sides after passing through the middle sleeve 341, and forms a continuous connection along the length direction of the sunshade cloth in cooperation with the clamping action of the pipe clamp 53, effectively disperses the wind load stress, and avoids local tearing; at the same time, the closed design of the outer end of the rod sleeve 342 prevents the connecting rod 343 from slipping off, ensures that the cloth surface is tensioned flat, and the detachable structure of the sleeve 341 and the pipe clamp 53 facilitates local replacement or maintenance of the sunshade cloth, and takes into account the installation convenience, wind resistance stability and maintenance efficiency.

[0122] The operation method of the box-type storage electric vehicle sunshade rain cover device is as follows:

[0123] S1: Storage device preparation. Before use, ensure that the sunshade rain cover device has been correctly installed on the head or handle of the electric vehicle, and that the shading assembly 32 in the storage box 1 has been completely wound. In this state, the shading assembly 32 is completely stored in the storage box 1, avoiding occupying additional space and not affecting the normal use of the electric vehicle.

[0124] S2: Unfolding the shading assembly 32. When the user needs to unfold the sunshade and rain shelter, first pull the crossbar 33 outwards through the entrance on the storage box 1, thus unfolding the support component 4. The support sub-bar at the bottom of the support component 4 will slide and unfold along the width direction of the shading assembly 32 according to the guidance of the track 41. Through manual or automatic operation, the reel 31 in the winding component 3 starts to rotate, driving the transparent film 321 and the sunshade and rain shelter cloth 322 of the shading assembly 32 to unfold together. At this time, the first end of the shading assembly 32 is fixed on the reel 31, and the second end is connected with the support component 4 through the crossbar 33, forming the effect of sunshade or rain shelter.

[0125] S3: Positioning the support component 4. When unfolded, the first folding support bar assembly 42 and the second folding support bar assembly 43 of the support component 4 are gradually unfolded under the guidance of the track 41, and the connecting parts between the support bar elements 5 ensure that the support component 5 stably supports the shading assembly 32, forming an arc-shaped support structure. The cross structure and sliding design of the support bar ensure that the entire support system is stable, firm, and can effectively withstand external pressure such as wind or rain.

[0126] S4: Fixing the shading assembly 32. After the shading assembly 32 is completely unfolded, the user hangs the hook on the crossbar 33 on the hooking point at the back of the electric vehicle through the hooking rope, further enhancing the stability of the sunshade and rain shelter. The hooking rope ensures that the shading assembly 32 will not displace during use due to wind or other external forces through fixed connection.

[0127] S5: Storing the shading assembly 32. After use, the user only needs to release the connection of the hooking rope, and holds the crossbar 33 with his hand to make the shading assembly 32 and the support component 4 move towards the storage box 1 at a controllable speed, and the reel 31 automatically reverses to rotate, winding the transparent film 321 and the sunshade and rain shelter cloth 322 back into the storage box 1. The support component 4 will also fold back into the storage box 1 through the track 41. The storage design of the shading assembly 32 and the support component 4 is simple and convenient, ensuring that the equipment can quickly recover to a compact and neat state, saving space and preparing for the next use.

[0128] Through these operation steps, the user can easily and efficiently unfold and store the sunshade and rain shelter, providing convenient sunshade and rain shelter function in various weather conditions, while maintaining the neatness and convenient storage of the sunshade and rain shelter.
