Description

TECHNICAL FIELD

[0001] The utility model relates to the accessory field for sunshade and rain shelter of electric vehicle, concretely relates to a sunshade and rain shelter device of electric vehicle of exempted from curling box type storage. BACKGROUND

[0002] With the wide application of electric vehicles in urban short-distance travel, users have higher demands on the use comfort of electric vehicles in different weather conditions. In the scorching sun or rainy weather, electric vehicle drivers and passengers urgently need reliable sunshade and rain shelter devices to improve the travel experience. Although the existing sunshade and rain shelter devices of electric vehicles can meet the sunshade and rain shelter function to a certain extent, there is still room for improvement in terms of storage convenience, structural compactness and use cost, especially the inherent defects of traditional winding structure, which become the factors restricting the development of the industry.

[0003] At present, the mainstream sunshade and rain shelter devices of electric vehicles on the market generally use a winding shaft or similar winding component. Such devices usually completely fix the shielding assembly (such as sunshade cloth, rainproof film, etc.) on the winding shaft or winding component, and realize the expansion and storage of the shielding assembly through the rotation of the winding shaft. The connection mode of the support structure and the shielding assembly also depends on the mechanical linkage of the winding component, resulting in that the core function of the entire device is highly concentrated in the winding component. Such design has certain practicability in early application, but as users' requirements for portability and space utilization continue to improve, its inherent defects gradually appear.

[0004] The above design based on the winding shaft or winding component has multiple technical bottlenecks: first, since the shielding assembly needs to be completely wound or stored in the winding shaft or winding component, the overall volume and weight of the device increase significantly with the increase of the shielding area. The rigid structure of the winding shaft and the requirement for the tension of the shielding assembly during winding further increase the material cost and processing difficulty, especially when folding and storing, the diameter of the winding shaft and the winding radius of the shielding assembly are difficult to compress, causing the device to have a large volume after storage, affecting the driving experience and operation stability of the user. Second, the portability is insufficient. The traditional device is difficult to achieve flexible folding due to the rigid support of the winding shaft component in the storage state, and the large storage volume becomes a burden. In addition, uneven winding, jamming and other problems of the shielding assembly may occur during the winding process of the winding shaft, which may cause material wear or structural deformation after long-term use, affecting the service life of the device. Third, the complexity of the structure increases the manufacturing cost. The winding shaft and the matching transmission and limiting components need to be precisely machined to ensure smooth winding, increasing the production and assembly difficulty. SUMMARY

Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0071] Example 1

[0072] like Figures 1 to 7 As shown, this utility model embodiment provides a roll-up, box-type storage device for electric vehicles that provides sun and rain protection, comprising:

[0073] Storage box 1, which has an inlet and an outlet and a bottom plate 2; the inlet and outlet can be located on the top or side of the storage box 1;

[0074] The support component 4 is provided with a shielding component 32. The support component 4 and the shielding component 32 can be folded and stored inside the storage box 1, and can be unfolded to the outside of the storage box 1 through the inlet and outlet to support the shielding component 32. The first end of the support component 4 is rotatably connected to the base plate 2.

[0075] In some embodiments, the storage box 1 is a hollow shell with an arc-shaped or streamlined front wall. An entrance / exit communicating with the internal space is provided on its top or side. The width of this entrance / exit is adapted to the width of the support member 4 after it is unfolded, ensuring that the support member 4 and the shielding assembly 32 can smoothly enter and exit. The base plate 2 of the storage box 1 is a horizontally arranged flat plate structure, fixed to the front frame of the electric vehicle or a mounting bracket for installing a rearview mirror by bolts or other means. The base plate 2 is provided with a rotating connection part, for example... Figure 7 and Figure 8 The first pivot 6 shown is used to receive and rotate the first end of the connecting support member 4.

[0076] In some embodiments, the support component 4 is a foldable linkage mechanism, including symmetrically arranged left and right support arms, each support arm being composed of a plurality of articulated links, adjacent links being rotatable about the articulation points to achieve folding or unfolding. The first end of the support component 4, i.e. the end close to the base plate 2, is provided with a rotating shaft 63, which cooperates with the rotating connection portion of the base plate 2 to enable the support component 4 to rotate in the vertical plane about the base plate 2. The shielding assembly 32 can be a waterproof coated sunshade cloth (awning cloth) and a transparent film, the edges of which are fixed to the linkage mechanism of the support component 4 by magic tape or buckles, and the rear part of the sunshade cloth or awning cloth is provided with a light-transmitting window to enable the driver to observe the rear view. When the support component 4 is unfolded, the sunshade cloth is stretched tightly to form an arc-shaped, curved or dome-shaped shielding structure; when the support component 4 is folded, the sunshade cloth naturally folds with the folding of the linkage mechanism, avoiding curling and deformation.

[0077] In some embodiments, the storage box 1 can be made of lightweight high-strength ABS engineering plastic, and the base plate 2 is made of lightweight plate material to reduce the overall weight and improve corrosion resistance; the links of the support component 4 can be made of carbon fiber pipe material to reduce the self-weight while ensuring the structural strength, and the hinge component can be made of stainless steel to enhance wear resistance. The base plate 2 of the storage box 1 is connected to the mounting bracket at the front end of the electric vehicle by bolts, and a plurality of adjustment holes can be further provided on the mounting bracket to adapt to the frame sizes of different models of electric vehicles, achieving universal installation. The edges of the sunshade cloth of the shielding assembly 32 are provided with elastic edges, which can be connected to the linkage mechanism of the support component 4 by cooperating the metal ring buckles on the edges with the hooks on the links, ensuring firm connection and easy disassembly and replacement.

[0078] In some embodiments, the upper end of each support rod unit 5 is detachably connected to the shielding assembly 32 by a detachable connecting piece;

[0079] The detachable connecting piece is a snap fastener, which includes a snap fastener male head fixed to the upper end of the support rod unit 5 and a snap fastener female seat sewn at the corresponding position of the shielding assembly 32, and the snap fastener male head and the snap fastener female seat are detachably connected by pressing and buckling; wherein the positions of the snap fastener male head and the snap fastener female seat can be interchanged; or,

[0080] The detachable connecting piece is a magic tape, which includes a nylon hook surface attached to the surface of the upper end of the support rod unit 5 and a polyester pile surface sewn at the corresponding position of the shielding assembly 32, and the nylon hook surface and the polyester pile surface are detachably connected by hooking and sticking; wherein the positions of the nylon hook surface and the polyester pile surface can be interchanged; or,

[0081] The detachable connecting piece is a magnetic buckle, which includes a magnet piece attached to the upper end of the support rod unit 5 and a metal piece sewn on the corresponding position of the shielding assembly 32. The magnet piece and the metal piece are attracted by magnetic force to form detachable connection. The setting positions of the nylon hook surface and the polyester fleece surface can be exchanged with each other; or,

[0082] The detachable connecting piece is a hook and loop buckle assembly, which includes a hook fixed to the upper end of the support rod unit 5 and a loop buckle sewn on the corresponding position of the shielding assembly 32. The hook is hooked into the loop buckle to form detachable connection. The setting positions of the hook and the loop buckle can be exchanged with each other; or,

[0083] The detachable connecting piece includes at least two of the snap, the waterproof magic tape, the magnetic buckle and the hook and loop buckle assembly, and different types of detachable connecting pieces are distributed along the length direction of the support part 4.

[0084] The specific operation process of unfolding and storing is as follows:

[0085] When the sun-shading and rain-shielding function is needed, the user holds the second end of the support part 4, i.e. the end away from the bottom plate 2, and pulls it out of the entrance of the storage box 1. During the movement, each connecting rod rotates around the hinge point in turn to unfold until the support part 4 forms a stable arc-shaped support frame. At this time, the shielding assembly 32 is completely unfolded and tensioned and fixed by the arc-shaped support frame, and is further connected to the frame at the rear of the electric vehicle through the hook or the binding rope. When it is needed to be stored, the hook or the binding rope is loosened, and the support part 4 is pushed towards the storage box 1. Under the action of the pushing force, each connecting rod is folded in the opposite direction, and at the same time, the shielding assembly 32 is naturally folded into a flat layered structure along with the folding of the connecting rod mechanism. Finally, the support part 4 and the shielding assembly 32 are completely stored in the storage box 1.

[0086] Embodiment two

[0087] As shown in Figure 5 and Figure 6 In some embodiments, the support part 4 can include a track 41 fixedly arranged on the bottom plate 2 and extending along the width direction of the shielding assembly 32. The two end portions of the track 41 are provided with a baffle or are in a closed state. A first folding support rod assembly 42 and a second folding support rod assembly 43 are arranged along the length direction of the track 41. The first folding support rod assembly 42 and the second folding support rod assembly 43 each include a plurality of support rod units 5, each of which is composed of two support sub-rods hingedly connected at the middle points. The adjacent support rod units 5 are hingedly connected at the end portions. The lower end of the first support sub-rod 51 of the bottom layer support rod unit 5 is pivotally connected to the bottom plate 2 as a first end, and the lower end of the second support sub-rod 52 of the bottom layer support rod unit 5 can slide in the track 41. The upper end of the top layer support rod unit 5 is provided with a cross rod connecting portion 33a (see Figure 3), for connecting with the cross bar 33 of the shelter assembly 32; the upper end of each support pole unit 5 is detachably connected with the shelter assembly 32.

[0088] In one embodiment, the upper end of each support pole unit 5 is provided with one or more pipe clamps 53 correspondingly, the pipe clamps 53 are used for penetrating the connecting rod 325 (see Figure 10 ), so as to set the shelter assembly 32 on the first folding support pole assembly 42 and the second folding support pole assembly 43.

[0089] As shown in Figure 6 , in some embodiments, the shelter assembly 32 includes a transparent film 321 and a sunshade rain cloth 322. As shown in Figure 10 , the shelter assembly 32 is provided with a plurality of fixing assemblies along the length direction, each fixing assembly includes a sleeve 323 provided at the middle of the width direction of the shelter assembly 32, the sleeve 323 has openings at both axial ends; a rod sleeve 324 provided at the side edges of the width direction of the shelter assembly 32, the outer end of the rod sleeve 324 is closed and the inner end has an opening; and a connecting rod 325; as shown in Figure 9 , each fixing assembly corresponds to a plurality of pipe clamps 53 provided at the same height; the connecting rod 325 is inserted into the corresponding rod sleeve 324 after penetrating through the corresponding sleeve 323 and pipe clamp 53.

[0090] As shown in Figure 5 and Figure 6 , specifically, the support part 4 includes a track 41 fixed on the bottom plate 2, a first folding support pole assembly 42 and a second folding support pole assembly 43. The track 41 is made of light materials such as plastic, and is fixed horizontally on the upper surface of the bottom plate 2 along the width direction of the shelter assembly 32, i.e. left and right of the electric vehicle, the both ends of the track 41 are provided with baffles perpendicular to the extension direction of the track, for limiting the stroke range of the support sub-pole at the bottom. The first folding support pole assembly 42 and the second folding support pole assembly 43 are arranged along the length direction of the track 41, the structures of the two assemblies are symmetrical and move synchronously, and they jointly support the shelter assembly 32.

[0091] Specifically, the first folding support pole assembly 42 and the second folding support pole assembly 43 are each composed of a plurality of support pole units 5, each of which is formed by two support sub-poles of equal length hinged at the midpoint by a pin, forming an "X" type structure that can rotate around the midpoint. The adjacent support pole units 5 are connected in a head-to-tail hinged manner, i.e. the top end of the support sub-pole of the previous support pole unit 5 is connected to the bottom end of the support sub-pole of the next support pole unit 5 by a hinge. Specifically, the end (top end) of the support sub-pole of the previous unit is provided with a hinged lug, and the starting end (bottom end) of the support sub-pole of the next unit is provided with a corresponding hinged hole, and the rotation connection is achieved by passing a pin through the lug and the hinged hole, thereby forming a chain drive structure that can be folded and expanded. For the bottom layer support pole unit 5, i.e. the support pole unit 5 close to the bottom plate 2, the lower end of the first support sub-pole 51 is pivoted to the bottom plate 2 by a fixed pin, so that the entire support pole assembly can rotate around the pivot point; the lower end of the second support sub-pole 52 of the support pole unit 5 close to the bottom plate 2 is provided with a sliding block with a ball, which is embedded in the sliding groove of the track 41 and can slide along the track 41. Through the movement of the sliding block in the track, combined with the rotation of the pivot point, the folding and unfolding of the support pole assembly is achieved. The upper end of the top layer or the uppermost layer of the support pole unit 5, i.e. the support pole unit 5 away from the bottom plate 2, is provided with a crossbar connecting part 33a (see Figure 3 ), which is used for plug-in connection with the crossbar 33 of the shielding assembly 32. The upper end of each support pole unit 5 is provided with 1-2 pipe clamps 53, the opening direction of which is substantially horizontal or towards the connecting rod 325, for passing the connecting rod 325 of the shielding assembly 32. The support sub-pole can have a small or slightly curved angle, for example but not limited to 1.5 degrees, 2 degrees, 3 degrees, 4 degrees, 5 degrees, etc. The curved angle is the included angle between the direction of the support sub-pole after bending and its original direction (assuming horizontal direction), which is beneficial to form an arc-shaped support structure after the first folding support pole assembly 42 and the second folding support pole assembly 43 are unfolded, and to support the shielding assembly.

[0092] As Figure 10As shown, the shielding assembly 32 is spaced apart along the length direction of the electric vehicle, i.e. the front-rear direction of the electric vehicle, and is provided with a plurality of fixing assemblies corresponding to the number of support rod units 5, each of which includes a middle sleeve 323, two side rod sleeves 324 and a connecting rod 325. The middle sleeve 323 is arranged (e.g. sewn or bonded) at the middle position of the shielding assembly 32 in the width direction, the two ends of the sleeve 323 are provided with openings, and the sleeve 323 is in the shape of a hollow cylinder or a semi-cylinder, the inner diameter of the sleeve 323 is matched with the diameter of the connecting rod 325, and the sleeve 323 is arranged on the connecting rod 325. The two side rod sleeves 324 are arranged at the two side edges of the shielding assembly 32 in the width direction, the outer end (i.e. the closed end) of the rod sleeve 324 is closed, i.e. the end close to the edge of the shielding assembly 32 is closed, the inner end of the rod sleeve 324 is provided with an opening, i.e. the end close to the middle sleeve 323 is provided with an opening, and the internal length of the rod sleeve 324 is slightly larger than the length of the inserted end of the connecting rod 325. The connecting rod 325 can be a round rod or a square rod, and the length of the connecting rod 325 is slightly smaller than the width of the shielding assembly 32.

[0093] When installed, the connecting rod 325 is sequentially inserted through the pipe clamp 53 at the upper end of the support rod unit 5, the middle sleeve 323, and then the two ends of the connecting rod 325 are inserted into the two side rod sleeves 324, and the closed end of the rod sleeve 324 limits the connecting rod 325, ensuring that the connecting rod 325 is fixedly connected with the shielding assembly 32. Since the pipe clamp 53 is fixed with the upper end of the support rod unit 5, when the support rod assembly is unfolded or folded, the connecting rod 325 drives the shielding assembly 32 to move synchronously through the pipe clamp 53, and the cooperation structure of the middle sleeve 323 and the rod sleeve 324 can prevent the shielding assembly 32 from being deviated or torn under stress.

[0094] The operation process of unfolding and storing the device is as follows: when the device needs to be unfolded, the user pulls the cross rod 33 towards the tail of the electric vehicle, the sliding block at the lower end of the second support sub-rod 52 moves in the track, driving the first support sub-rod 51 at the bottom to rotate around the pivot point of the bottom plate 2, and the plurality of support rod units 5 at the upper layer are gradually unfolded through the hinge points between the support rod units 5, forming a three-dimensional support frame. Since the support rod unit 5 is fixed through the pipe clamp 53 and the connecting rod 325, the transparent film 321 and the sunshade rain cloth 322 are unfolded flat during the unfolding process, avoiding curling or wrinkling. When storing, the user pushes the cross rod 33 towards the head of the electric vehicle, the sliding block at the lower end of the second support sub-rod 52 moves away from the baffle at the end of the track 41, the support rod assembly is gradually folded and the height is lowered to be stored in the inside of the storage box 1, the shielding assembly 32 is synchronously lowered with the connecting rod 325, and finally the folded support rod assembly and the shielding assembly are stored in the storage space on the side of the track 41.

[0095] The pin shaft of the support rod unit 5 is made of stainless steel or plastic material, and elastic clamping springs are arranged at both ends of the pin shaft to prevent falling off. The pipe clamp 53 is a plastic injection molding part, and the inner wall can be further provided with anti-skid lines to enhance the clamping force on the connecting rod 325. The rod sleeve 324 and the shielding assembly 32 are fixed by double-thread sewing. The bottom plate 2 and the track 41 are connected by a countersunk bolt. The rod sleeve 324 and the shielding assembly 32 are fixed by double-thread chain sewing process. The edges of the rod sleeve 324 and the corresponding positions of the shielding assembly 32 are simultaneously sewn by two sewing threads to form a double-thread interlaced lock edge structure, which ensures that there is no risk of tearing at the connection part of the rod sleeve 324 and the shielding assembly 32 when the sunshade rain cloth 322 is subjected to wind force or gravity.

[0096] Example Three

[0097] As shown in Figure 6 and Figure 7 In some embodiments, the bottom layer support rod unit 5 is provided with a guide mechanism at the lower end of the second support sub-rod 52 which slides along the track 41. The track 41 includes oppositely arranged first track wall 411 and second track wall 412, and the first track wall 411 and the second track wall 412 form a recessed space 413 which accommodates the guide mechanism. The bending directions of the first support sub-rod 51 and the second support sub-rod 52 are the same.

[0098] In some embodiments, 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 lower end of the first support sub-rod 51 of the first folding support rod assembly 42 of the bottom layer; and the second pivot seat 7 forms a rotary pair with the lower end of the first support sub-rod 51 of the second folding support rod assembly 43 of the bottom layer.

[0099] In some embodiments, the inner 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 which extend along the width direction of the shielding assembly 32; the guide mechanism includes a sliding part arranged at the lower end of the second support sub-rod 52, and the sliding part is slidingly arranged in the first groove 414 and the second groove 415.

[0100] In some embodiments, the first and second pivot seats 6 and 7 respectively include first and second support seats 61 and 62 fixed on both sides of a mounting base arranged at the bottom of the first and second support seats 61 and 62 for support, and the mounting base is fixed on the bottom plate 2. In some embodiments, the mounting base can be omitted, so that the first and second support seats 61 and 62 are directly mounted on the bottom plate 2. The first and second support seats 61 and 62 are provided with through holes for passing through a rotating shaft 63, and the rotating shaft 63 passes through the through holes of the first and second support seats 61 and 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 rotating shaft. The second support seat 62 is closer to the tail of the electric vehicle than the first support seat 61, and the height of the second support seat 62 is higher than that of the first support seat 61, which is conducive to providing better support to the first support sub-rod 51 at the bottom layer of the first and second folding support rod assemblies 42 and 43, making the device more firm and solid, and reducing the swing amplitude of the device when riding at high speed or in strong wind. 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, which is also conducive to providing similar support and stability to the second support sub-rod 52 at the bottom layer of the first and second folding support rod assemblies 42 and 43 through the second track wall 412, making the device more firm and solid, and reducing the swing amplitude of the device when riding at high speed or in strong wind.

[0101] Specifically, the second support seat 62 (close to the tail) is higher than the first support seat 61, forming an inclined support structure with the front low and the rear high. In mechanics, this design can make the rotating shaft 63 of the support component form a certain inclination angle. When the sun-shading and rain-shielding device is unfolded, the higher support point at the rear can provide greater vertical support force and anti-overturning moment, which can effectively reduce the swing amplitude and improve the overall stability, especially when subjected to lateral wind force (such as strong wind) or air resistance when riding.

[0102] Specifically, the second track wall 412 (close to the tail) is higher than the first track wall 411, which cooperates with the height difference of the support seats. As a guide structure of the sliding component, the higher track wall at the rear can limit the backward inclination angle of the support rod assembly during sliding, which further restricts the swing degree of freedom of the support rod assembly in cooperation with the inclined support of the support seat. Especially when riding at high speed, the aerodynamic load mainly acts on the front of the device, and the higher support structure at the rear can effectively offset the tendency to lean forward and reduce the swing amplitude.

[0103] Embodiment four

[0104] In some embodiments, the lengths of the plurality of sets of support rod units 5 decrease successively along a direction from the bottom layer to the top layer; or, the plurality of sets of support rod units 5 include support rod units 5 with a first length at the bottom layer, support rod units 5 with a second length at the middle layer, and support rod units 5 with a third length at the top layer; the first length is greater than the second length, and the second length is greater than the third length.

[0105] The use of support rod units with successively decreasing lengths from the bottom layer to the top layer (first length > second length > third length) in the support member can form a support structure that is narrow at the top and wide at the bottom. This design has several advantages. On the one hand, the longer support rod units at the bottom layer can expand the support span with the bottom plate and the track, providing a more stable foundation support for the entire device. In particular, when the bottom layer support rod units are hinged to the bottom plate and the sliding block moves along the track, the long-span structure can effectively disperse external loads (such as wind force and gravity), reduce the intensity of single-point stress, and improve the anti-overturning ability. On the other hand, the shorter support rod units at the top layer can shorten the overhang length of the shading assembly, reduce the wind resistance moment in high-speed riding or strong wind environments, and form a stable structure with the wide support at the bottom layer, reducing the swing amplitude of the device. In addition, the design of successively decreasing lengths allows the support rod assembly to be folded layer by layer when folded for storage, with the long rods at the bottom layer stored in the track and the short rods at the top layer stacked successively, forming a compact layered storage structure. Compared to parallel folding of equal-length rods, this design can further reduce the storage volume, improve space utilization, and ensure that the shading assembly is stored flat.

[0106] In some embodiments, the electric vehicle sunshade and rain protection device with a non-curling box storage includes any one or more of the following: the bottom plate 2 is provided with at least one hollow water leakage hole; the storage box 1 has an arc-shaped front wall body, the bending direction of the front wall body is towards the tail direction of the electric vehicle, the bottom of the front wall body is provided with a transparent water curtain; the area of the entrance and exit is smaller than the area of the bottom plate 2. In some embodiments, the first folding support rod assembly 42 and the second folding support rod assembly 43 each include 4 to 8 support rod units 5.

[0107] In the embodiment, the hollow water leakage hole of the bottom plate 2 can timely drain the accumulated water in the storage box 1, avoid the rusting of the support component and the mildewing of the shielding assembly caused by the long-term retention of rainwater, and prolong the service life of the device. The arc-shaped front wall body of the storage box 1 is curved towards the tail direction, which not only conforms to the aerodynamic principle, reduces the wind resistance and noise during riding, but also forms a flexible waterproof barrier by the transparent water-blocking curtain such as a PVC soft film at the bottom, effectively blocks the rainwater from pouring into the inside of the storage box from the entrance, and the transparent material does not affect the observation of the driver to the rear environment. The design that the area of the entrance is smaller than the bottom plate 2 makes the storage box form a stable structure with a wide bottom and a narrow opening, the larger contact area of the bottom plate 2 provides a more stable installation basis for the device, reduces the shaking during riding, and the narrow entrance limits the folded support component and shielding assembly, avoids the risk of curling or damage caused by the protruding of the components during storage. In addition, the first folding support rod assembly 42 and the second folding support rod assembly 43 adopt the number configuration of 4 to 8 support rod units 5, which optimizes the balance between support strength and folding convenience: when the number of units is moderate, a reasonable support frame can be formed after unfolding, the wind force or gravity borne by the shielding assembly is evenly dispersed, and local overloading is avoided; when folding, the multiple rod bodies can be closely overlapped, and if the length decreases, the storage volume can be further reduced, the limited space of the electric vehicle is met, and the user's operation is facilitated, and the use experience is improved.
