[0059] Storage box 1, the access is provided on the storage box 1;

[0060] Bottom plate 2, is arranged in storage box 1, or the bottom plate 2 as the bottom wall of the storage box 1;

[0061] Winding component 3, the winding component 3 includes the reel 31 being arranged on the bottom plate 2 and the shielding assembly 32 being wound on the reel 31, the reel 31 can be wound in the shielding assembly 32 in the storage box 1 inside or to the outside of the storage box 1 is unfolded when rotating;The first end of the shielding assembly 32 is connected with the reel 31, and the second end of the shielding assembly 32 is provided with cross bar 33;

[0063] The storage box 1 in the embodiment can be made of high-strength plastic material, has sufficient durability and pressure resistance. The storage box 1 is designed as a rectangle or a rectangle, which can be closely matched with the electric vehicle frame. One side of the storage box 1 is provided with an access, which serves as an unfolding and storage channel for the shielding assembly 32 and the support component 4. The size of the access 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 optimized to 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 Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 And Figure 10As shown, the bottom plate 2 is arranged inside the storage box 1 as the bottom wall of the entire device, supporting the shielding assembly 32, the reel 31, the support component 4 and other components of the device. The bottom plate 2 can be made of corrosion-resistant and wear-resistant materials to ensure that it is not affected by environmental factors during long-term use. The size of the bottom plate 2 matches the internal size of the storage box 1, which can fix the components of the device and prevent them from loosening or shifting during storage or deployment. The design of the bottom plate 2 not only considers the load-bearing capacity of the device, but also takes into account the support area required when the shielding assembly 32 is deployed.

[0065] As shown in FIG. 1, the device comprises a storage box 1, a bottom plate 2, a winding component 3, a support component 4 and a shielding assembly 32. Figures 2 to 6 As shown, the winding component 3 is composed of a reel 31 and a 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 deploy the shielding assembly 32, the reel 31 can be rotated by simple manual operation or mechanical device to deploy the shielding assembly 32 outside the storage box 1. When the user no longer needs to use it, the shielding assembly 32 can be rewound into the storage box 1 by the reverse rotation operation. The first end of the shielding assembly 32 is connected to the reel 31 through a suitable connecting device, ensuring that the shielding assembly 32 can be evenly and firmly deployed and stored when the reel 31 rotates. The second end of the shielding assembly 32 is connected to a crossbar 33, which can be pulled by the user to drive the shielding assembly 32 to expand towards the tail of the electric vehicle.

[0066] The support component 4 adopts a folding design, which can be stacked or stacked in the storage box 1 when not in use, and deployed through the entrance to support the shielding assembly 32 below the shielding assembly 32. The first end of the support component 4 is fixedly connected to the bottom plate 2, which adopts a hinge or other foldable connection method, so that the support component 4 can be easily folded and stored. The second end of the support component 4 is connected to the crossbar 33 of the shielding assembly 32. The design of the support component 4 not only considers its load-bearing capacity, but also fully considers the volume after folding and the convenience of storage.

[0067] The present application provides a compact and convenient electric vehicle sunshade and rainproof device, which can effectively shield the sun and rain under different weather conditions, and has good storage performance and use convenience. The design of the device not only improves the use comfort of the electric vehicle, but also effectively saves space.

[0068] Embodiment two

[0069] In some embodiments, as shown in FIG. 1, the support component 4 comprises: Figures 3 to 6

[0070] The track 41 is arranged on the bottom plate 2 and extends along the width direction of the shielding assembly 32.

[0071] ​The first folding support rod assembly 42 and the second folding support rod assembly 43 are arranged at intervals along the width direction of the shielding assembly 32;

[0072] The first folding support rod assembly 42 and the second folding support rod assembly 43 respectively comprise:

[0073] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10 indicated, a plurality of groups of cross-arranged support rod units 5, each group of support rod units 5 comprising two support sub-rods, the midpoints of the two support sub-rods being rotationally connected; the two upper ends of a group of support rod units 5 in any adjacent two groups of support rod units 5 in the lower layer are rotationally connected with the two lower ends of a group of support rod units 5 in the adjacent upper layer; the lower end of the first support sub-rod 51 in the group of support elements in the bottom layer is connected with the bottom plate 2, and the lower end of the second support sub-rod 52 in the group of support elements in the bottom layer is limited in the track 41 to be able to slide only along the width direction of the shielding assembly 32; the upper end of a support sub-rod in the group of support elements in the top layer is rotationally connected with the cross bar 33.

[0074] Specifically, the track 41 is arranged on the bottom plate 2 and extends along the width direction of the shielding assembly 32. The track 41 provides a sliding and guiding path, and the material of the track 41 can be a high-strength and wear-resistant plastic material to ensure sufficient durability in frequent use. The length and width of the track 41 are accurately designed to ensure that the support rod assembly can slide smoothly and be accurately positioned without deviation or jamming.

[0075] The first folding support rod assembly 42 and the second folding support rod assembly 43 are arranged at intervals along the width direction of the shielding assembly 32 and are respectively located on both sides of the shielding assembly 32. Each support rod assembly is composed of a plurality of groups of cross-arranged support rod units 5. Each group of support rod units 5 comprises two support sub-rods, and the midpoints of the two support sub-rods are rotationally connected to form a support point. Through this design, the support rod assembly can provide stronger stability when unfolded and can be effectively accommodated when folded.

[0076] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 9 and Figure 10As shown, the midpoints of two support sub-poles in each support pole unit 5 are rotationally connected, and the connection between any two adjacent support pole units 5 is designed such that the lower end of the upper support pole unit 5 is rotationally connected to the upper end of the lower support pole unit 5. This cross design enables each support pole unit 5 to form a stable support frame when unfolded, providing effective support force to prevent the shelter assembly 32 from sagging or tilting during use. The cross structure of the support pole unit 5 enhances the stability of the entire support component 4, making it more suitable for use in windy and rainy weather.

[0077] In the bottommost support pole unit 5, the lower end of the first support sub-pole 51 is connected to the bottom plate 2, and the lower end of the second support sub-pole 52 is limited within the track 41 and can only slide along the extension direction of the track 41. This design ensures that the support pole assembly can slide smoothly along the track 41 when unfolded, and will not be misaligned or jammed when folded. In addition, the sliding characteristics of the support pole unit 5 also ensure that the support component 4 can be folded to the most compact position when not needed for support, without occupying extra space.

[0078] Figure 2 、 Figure 3 and Figure 8 As shown, in the topmost support pole unit 5, the upper end of one support sub-pole is rotationally connected to the crossbar 33. Through this design, when the user pulls out or retracts the crossbar 33, it can simultaneously drive the unfolding and folding of the shelter assembly 32 and the support component 4, providing convenience for the user.

[0079] The design of the support component 4 of the present embodiment, which guides and folds the support pole assembly through the track 41, not only makes the support component 4 have strong stability and wind resistance, but also optimizes the folding process. Through the cross design of the support pole unit 5, the support force is effectively distributed, and the shelter assembly 32 can remain stable under different weather conditions. In addition, the folding design enables the support component 4 to be effectively stored in the storage box 1 when not in use, saving space and improving convenience.

[0080] Embodiment Three

[0081] In some embodiments, as shown in Figures 1 to 6 and Figure 10 The bottom plate 2 is provided with a first pivot seat 6 and a second pivot seat 7 on both sides of the length direction of the track 41, and the track 41 is arranged between the first pivot seat 6 and the second pivot seat 7; the first pivot seat 6 is connected to the lower end of the first support sub-pole 51 in the bottommost group of support elements in the first folding support pole assembly 42; and the second pivot seat 7 is connected to the lower end of the first support sub-pole 51 in the bottommost group of support elements in the second folding support pole assembly 43.

[0082] In some embodiments, as shown in Figures 1 to 6 and Figure 10 The track 41 comprises first and second track walls 411 and 412 arranged at intervals, and a recessed space 413 is formed between the first and second track walls 411 and 412 for the lower end of the second support sub-bar 52 of the two groups of support elements in the bottom layer to be inserted. The inner surfaces of the opposite walls of the first and second track walls 411 and 412 are respectively provided with a first groove 414 and a second groove 415 extending along the width direction of the shielding assembly 32. The lower end of the second support sub-bar 52 of the two groups of support elements in the bottom layer is vertically connected with a sliding piece 8, respectively. The sliding piece 8 can slide in the first and second grooves 414 and 415.

[0083] In the present embodiment, the first and second pivot seats 6 and 7 are arranged on the bottom plate 2 and located on the two sides of the track 41. These pivot parts provide a rotating connection point for the support part 4. The support bar assembly is connected with the bottom plate 2 through the pivot parts to form a support structure. The first pivot seat 6 is connected with the lower end of the first support sub-bar 51 of the support element in the bottom layer of the first folding support bar assembly 42, and the second pivot seat 7 is connected with the lower end of the first support sub-bar 51 of the support element in the bottom layer of the second folding support bar assembly 43. This pivot mode enables the support part 4 to provide a firm support force when the shielding assembly 32 is unfolded and facilitates folding and retraction to save space when it is stored.

[0084] The track 41 in the present embodiment comprises first and second track walls 411 and 412, and a recessed space 413 is formed between the two track walls 41 for the lower end of the second support sub-bar 52 of the support element to be inserted. Through this design, the second support sub-bar 52 of the support element remains stable in the track 41 and can provide uniform support force when unfolded. The arrangement of the track walls 41 not only plays a role in positioning the support bar unit 5, but also ensures that the support bar unit 5 does not fall off or deviate when sliding.

[0085] In the present embodiment, the inner surfaces of the opposite walls of the first and second track walls 411 and 412 are respectively provided with a first groove 414 and a second groove 415 extending along the width direction of the shielding assembly 32. The design of these grooves enables the second support sub-bar 52 of the two groups of support elements in the bottom layer to slide accurately and stably support the shielding assembly 32 when unfolded. The arrangement of the first and second grooves 414 and 415 further improves the stability and smoothness of operation of the support part 4, reduces the friction between the support part 4 and the track 41, and avoids the problem of unstable support due to excessive resistance during use.

[0086] The lower end of the second support sub-bar 52 of the second group of support elements in the bottom layer is respectively connected with a sliding piece 8, and the two sliding bars can slide in the first groove 414 and the second groove 415. The design of the sliding bar enables the support element to smoothly slide in the track 41, providing better support force and flexibility. The material of the sliding bar can be a wear-resistant and low-friction material, such as stainless steel or plastic, to reduce wear during sliding and improve the durability and service life of the entire device. The sliding piece 8 can smoothly slide in the track 41, making the support element more convenient and stable during deployment and storage.

[0087] Embodiment Four

[0088] In some embodiments, as shown in Figs. 1 and 2, the shelter assembly 32 comprises a transparent film 321 and a sun / rain cover 322, one end of the transparent film 321 is fixed on the winding component 3, and the sun / rain cover 322 is connected to the rear end of the transparent film 321. Figure 3 Figure 5 The reel 31 can release the transparent film 321 and the sun / rain cover 322 through the exit when subjected to a pulling force, and automatically wind up the transparent film 321 and the sun / rain cover 322 through the exit when no external force is applied. The exit is provided on the top or side of the storage box 1.

[0089] In some embodiments, each of the support sub-bars is curved, and the curved portion of each support sub-bar corresponds to a central angle range of 0.5° to 3°. In this embodiment, the curved support sub-bar design is adopted, the main purpose of which is to form an arc-shaped support structure. Through this curved design, the support sub-bar can form a stable arc-shaped support surface when deployed, 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 use of the shelter assembly 32, and prevent the shelter assembly 32 from tilting or sagging. The curved shape can also improve the storage process, enabling the device to be folded more compactly, saving space, and improving overall convenience and aesthetics.

[0090] 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 an electric vehicle.

[0091] 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 an electric vehicle.

[0092] ​In some embodiments, the first folding support rod assembly 42 and the second folding support rod assembly 43 each comprises four to eight groups of cross-arranged support rod units 5, preferably six groups of cross-arranged support rod units 5. In this embodiment, the design of multiple groups of cross-arranged support rod units 5 can improve the stability and compression resistance of the support structure. Through cross-arrangement, the support rod units 5 can more evenly distribute external forces, enhancing the load-bearing capacity of the entire support system and preventing the support components 4 from tilting or deforming during use. In addition, the design of multiple groups of support rod units 5 allows the shelter assembly 32 to provide more balanced and powerful support when deployed, improving safety and reliability during use.

[0093] In some embodiments, the support components 4 are arranged closer to the tail direction of the electric vehicle relative to the winding components 3 in the storage state within the storage box 1.

[0094] In some embodiments, the hidden storage type electric vehicle sunshade and rain shelter device further comprises a hook rope arranged on the crossbar 33 for connecting with the hanging point at the rear of the electric vehicle; the end of the hook rope is provided with a hook for hooking the hanging point or hook point at the rear of the electric vehicle to fix the deployed shelter assembly 32.

[0095] The operation method of the hidden storage type electric vehicle sunshade and rain shelter device is as follows:

[0096] S1: Storage device preparation. Before use, ensure that the sunshade and rain shelter device has been correctly installed on the front or handle of the electric vehicle, and that the shelter assembly 32 in the storage box 1 has been completely wound. In this state, the shelter assembly 32 is completely stored in the storage box 1, avoiding occupying additional space and not affecting the normal use of the electric vehicle.

[0097] S2: Deploy the shelter assembly 32. When the user needs to deploy the sunshade and rain shelter device, first pull the crossbar 33 outward through the entrance of the storage box 1 to deploy the support components 4. The bottommost support sub-rod of the support components 4 will slide and deploy along the width direction of the shelter assembly 32 according to the guide 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 cloth 322 of the shelter assembly 32 to deploy together. At this time, the first end of the shelter assembly 32 is fixed on the reel 31, and the second end is connected with the support components 4 through the crossbar 33, forming the effect of sunshade or rain shelter.

[0098] S3: Positioning the support component 4. When unfolded, the first and second folding support rod assemblies 42 and 43 of the support component 4 are gradually unfolded under the guidance of the track 41, and the connecting parts between the support elements ensure that the support assembly stably supports the shielding assembly 32, forming an arc-shaped support structure. The cross structure and sliding design of the support rods ensure that the entire support system is stable, firm, and can effectively withstand external pressure such as wind or rain.

[0099] S4: Fixing the shielding assembly 32. After the shielding assembly 32 is completely unfolded, the user hooks the hooks on the crossbar 33 to the hanging points at the back of the electric vehicle through the hooking ropes, further enhancing the stability of the sunshade and rain shelter device. The hooking ropes are connected in a fixed manner, ensuring that the shielding assembly 32 does not displace during use due to wind or other external forces.

[0100] S5: Storing the shielding assembly 32. After use, the user only needs to disconnect the hooking ropes and hold the crossbar 33 with his hand to make the shielding assembly 32 and the support component 4 move towards the storage box 1 at a controllable speed, and the reel 31 automatically reverses to wind the transparent film 321 and the sunshade and rain shelter cloth 322 back into the storage box 1. The support component 4 is also folded back into the storage box 1 through the track 41 system. The storage design of the shielding assembly 32 and the support component 4 is simple and convenient, ensuring that the device can quickly recover to a compact and tidy state, saving space and preparing for the next use.

[0101] Through these operation steps, the user can easily and efficiently unfold and store the sunshade and rain shelter device, providing convenient sunshade and rain shelter functions in various weather conditions while maintaining the neatness and convenient storage of the device.

[0102] Example Five

[0103] The present embodiment provides a support component of a hidden storage type electric vehicle sunshade and rain shelter device, which comprises:

[0104] a bottom plate 2, which is fixedly connected with the bottom wall of the storage box or serves as the bottom wall of the storage box;

[0105] a track 41 fixedly arranged on the bottom plate 2 and extending along the width direction of the shielding assembly;

[0106] a first folding support rod assembly 42 and a second folding support rod assembly 43 arranged at intervals along the length direction of the track 41;

[0107] each of the first and second folding support rod assemblies 42 and 43 comprises:

[0108] a plurality of groups of cross-arranged support rod units 5, each group of support rod units 5 being composed of two support sub-rods hingedly connected at the middle points;

[0109] The adjacent support rod units 5 are connected by end hinges to form a foldable scissor linkage structure;

[0110] The lower end of the first support sub-rod 51 of the bottom layer support rod unit is hinged to the bottom plate 2, and the lower end of the second support sub-rod 52 is provided with a guide mechanism sliding along the track 41;

[0111] The upper end of the top layer support rod unit is provided with a crossbar connecting part 33a for being hinged to the crossbar 33 of the shielding assembly;

[0112] The track 41 comprises a first track wall 411 and a second track wall 412 arranged in parallel, and a recessed space 413 accommodating the guide mechanism is formed between the first track wall 411 and the second track wall 412.

[0113] The above technical solution has the advantages that: by arranging the symmetrically distributed scissor linkage structure and the sliding groove guide mechanism, the height compression of the support component in the storage state (the volume reduction ratio after folding can reach more than 5:1) and the rapid positioning after unfolding are realized. The cross-hinged support rod units form a stable arc-shaped support system, which can effectively disperse the wind load pressure and improve the overall stability of the sun-shading and rain-shielding device. The cooperation of the recessed space 413 and the guide mechanism ensures the accurate control of the motion trajectory during the folding process, avoids component interference, and at the same time, the parallel design of the first track wall 411 and the second track wall 412 enhances the torsional stiffness of the track, so that the support component can still maintain structural integrity in the vibration environment of the electric vehicle.

[0114] In a further embodiment, the bottom plate 2 is provided with a first pivot seat 6 and a second pivot seat 7 at both ends respectively; the first pivot seat 6 forms a rotary pair with the first support sub-rod 51 of the bottom layer of the first folding support rod assembly 42; and the second pivot seat 7 forms a rotary pair with the first support sub-rod 51 of the bottom layer of the second folding support rod assembly 43. By arranging the first pivot seat 6 and the second pivot seat 7, the first support sub-rod 51 of the bottom layer of the folding support rod assembly is connected to the track 41 in a rotary pair, which has the following advantages: the rigid connection of the pivot seat makes the load transmission path more clear, and finite element analysis shows that the maximum stress concentration can be reduced; the double-pivot seat design improves the synchronization of the unfolding actions of the two folding support rod assemblies, and the unfolding angle deviation is controlled within ±2°; the rotary pair structure reduces the friction loss of the metal contact surface, and tests show that the service life of the hinge part can be prolonged.

[0115] In a further embodiment, the inner parts of the opposite wall surfaces of the first track wall 411 and the second track wall 412 are respectively provided with a first groove 414 and a second groove 415 extending along the width direction of the shielding assembly 32;

[0116] The guiding mechanism comprises a sliding member 8 arranged at the lower end of the second support sub-rod 52, which is slidingly or translatablely arranged in the first and second grooves 414 and 415.

[0117] The inner walls of the first and second grooves 414 and 415 can be provided with a wear-resistant layer with a thickness of 0.5-2 mm. The sliding member can have a T-shaped cross-section or a conventional structure such as a shaft protrusion. In this embodiment, the T-shaped cross-section is adopted. The cooperation between the T-shaped cross-section of the sliding member 8 and the first and second grooves 414 and 415 has double advantages: the presence of the sliding member can prevent the sliding member from derailing, and the sliding member can still slide stably under the bumpy working condition of the electric vehicle; the 0.5-2 mm thickness of the wear-resistant layer is verified by tribology. When a 0.8 mm thick polytetrafluoroethylene coating is used, the friction coefficient is stable at 0.12-0.15 (ASTM D1894 standard test), and the wear rate can be reduced compared to the structure without coating. This thickness range ensures lubrication performance while avoiding the reduction of effective space of the sliding groove due to excessive thickness.

[0118] In further embodiments, the support sub-rod adopts an arc-shaped rod body structure with a curvature radius R satisfying 500 mm≤R≤3000 mm; and the spacing L between the hinge points of adjacent support rod units satisfies L=0.3-0.6 times the length of the support sub-rod. Through the arc-shaped structure design of the support sub-rod and the optimized layout of the hinge points, the bending resistance and storage efficiency of the rod member can be improved. The arc-shaped rod body forms a natural bending path when folded, avoiding component interference and enhancing the structural rigidity in the unfolded state. Reasonable hinge spacing design ensures the stability of the motion trajectory during folding, so that the support component achieves the best balance between compact storage and stable unfolding.

[0119] In further embodiments, the unfolding angle θ of the scissor linkage structure satisfies 60°≤θ≤120°, and the support component reaches the maximum unfolding height Hmax; the ratio of the maximum unfolding height Hmax to the storage height Hmin after folding is 5:1 to 8:1. Through the optimized unfolding angle range and height compression ratio design, the support component can not only realize a large range of sun-shading and rain-shielding coverage, but also maintain excellent storage performance. The specific angle threshold setting effectively prevents instability risk caused by over-unfolding of the mechanism, and the height compression ratio ensures that the device occupies the smallest space in the non-use state, adapting to the compact layout requirements of the electric vehicle carrier.

[0120] In further embodiments, the crossbar connecting part 33a is provided with a detachable interface, including: a clamping protrusion 33b arranged at the end of the crossbar 33; a clamping groove 33c arranged at the upper end of the top layer support rod unit; or a clamping groove 33c arranged at the end of the crossbar 33, and a clamping protrusion 33b arranged at the upper end of the top layer support rod unit; a rotating locking structure is formed between the clamping protrusion 33b and the clamping groove 33c.

[0121] The quick detachable interface with rotating locking mechanism greatly improves assembly efficiency, and the self-locking design simplifies the operation process while ensuring the reliability of the connecting part under dynamic load. The structure has good environmental adaptability and can maintain stable mechanical connection performance in complex working conditions.

[0122] In further embodiments, the support sub-rod is made of hollow aluminum alloy pipe or plastic; and the surface of the support sub-rod is provided with an anti-corrosion coating. The combination of hollow pipe and surface protection coating not only achieves lightweight but also improves the environmental durability of the component. Optimized material selection enables the support structure to have high strength and corrosion resistance, effectively coping with harsh conditions such as sun and rain in outdoor use, and prolonging the service life of the device.

[0123] In further embodiments, an angle limiting mechanism is provided in the scissor link structure, including: a limiting boss arranged at the hinge of adjacent support rod units; and a limiting groove arranged on the support sub-rod; when the unfolding angle reaches a set threshold, the limiting boss and the limiting groove form a mechanical stop. The mechanical angle limiting mechanism realizes reliable control of the unfolding angle through the precise matching of the boss and the groove. This design not only improves operational safety but also maintains structural stability under sudden external forces, preventing damage to the mechanism caused by accidental overload.

[0124] In further embodiments, the support component is made of rust-resistant aluminum alloy material as a whole, and the surface can be treated by anodizing; the hinge part is connected by a stainless steel shaft pin, and the shaft pin diameter d can satisfy: 3mm≤d≤6mm; a nylon bushing can be provided between the shaft pin and the support sub-rod, and the bushing wall thickness can be 0.5-1.0mm. The synergistic optimization of materials and processes enables the support component as a whole to have excellent weather resistance and durability. Anodizing treatment strengthens the surface protection performance, and cooperates with the hinge assembly to reduce the movement resistance while ensuring the long-term reliable operation of the connecting part, meeting the needs of high-frequency use of electric vehicles.
