Description

Technical Field

[0001] This utility model belongs to the field of rain canopies for two-wheeled electric vehicles, and particularly relates to a crossbar connecting device for a rain canopy bracket for electric vehicles. Background Technology

[0002] Existing electric vehicle rain canopies with a cross-link bracket structure use a circular hole at the top of one of the cross-links to connect a crossbar and secure the waterproof fabric. This prevents the crossbar and waterproof fabric from detaching from the link, which could cause the waterproof fabric to flutter in the wind and affect the stability of the rain canopy structure. The ends of the crossbar are connected to the sides of the waterproof fabric using connecting pieces. When packing the waterproof fabric with the crossbar attached, it must be packaged separately from the bracket. Since the bracket structure consists of multiple cross-links, assembling the waterproof fabric and bracket together would significantly increase the cargo volume. This would require transporting the folded, parallel-stacked links perpendicular to the front windshield, making both the bracket and waterproof fabric highly susceptible to damage during transport. However, if the waterproof fabric and bracket are packaged separately, the bracket, which can be placed parallel to the front windshield, is already quite thin. Therefore, packaging the waterproof fabric and bracket separately significantly reduces packaging thickness and volume, lowering shipping costs and box size, while also reducing the risk of component damage.

[0003] When customers receive the goods and install them, they need to first pull the two ends of the crossbar out of the connecting pieces on both sides of the waterproof cloth, disassemble the crossbar, then pass the two ends of the crossbar through the circular holes and connect them to the bracket, and finally put the two ends of the crossbar back into the connecting pieces. This installation method is complicated and cannot achieve quick disassembly and assembly, making it difficult for people who are not familiar with the structure to install. Summary of the Invention

[0004] The purpose of this utility model is to provide a crossbar connecting device for an electric vehicle canopy bracket. By setting a notch on the outside of the upper hinge point of the crossbar, the crossbar can be quickly disassembled and installed. The structure is simple and the operation is convenient.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

[0006] A crossbar connecting device for an electric vehicle canopy bracket includes two sets of identical brackets symmetrically arranged on the left and right sides. The brackets are composed of several sets of cross-arranged and connected end to end. Each set of cross-links includes a first link and a second link. In each set of cross-links, the tail end of the first link is hinged to the front end of the second link of the next adjacent set, and the tail end of the second link is hinged to the front end of the first link of the next adjacent set. The middle of the cross-links is movably hinged, and a notch is provided on the outer side of the upper hinge point of the cross-links. The notch is used to movably engage the crossbar, and the notch is a C-shaped opening.

[0007] Furthermore, the entrance width of the notch is slightly smaller than the outer diameter of the crossbar to prevent the crossbar from easily coming off under external force.

[0008] Furthermore, the notch is located at the top of the first link and is integral with the first link.

[0009] Furthermore, taking the horizontal center line of the notch as a reference line, the opening of the notch faces diagonally downwards from the reference line.

[0010] Furthermore, a locking plate is provided at the top of the second link. The height of the locking plate is sufficient to seal the gap until the crossbar cannot come out. The locking plate moves in an arc as the link unfolds or retracts, and its movement trajectory forms dynamic interference with the gap opening area.

[0011] Furthermore, the two ends of the crossbar are connected and fixed to both sides of the waterproof cloth covering the support above by connecting pieces.

[0012] The beneficial effects of this utility model are:

[0013] This invention features a notch on the outer side of the upper hinge point of the cross link, allowing the crossbar to be quickly detached from the bracket for disassembly and installation. This makes operation convenient, simplifies installation, saves transportation costs, and increases assembly efficiency. Furthermore, by setting a matching locking plate, the crossbar remains sealed within the notch during the folding and unfolding of the cross link, preventing it from detaching from the notch when the electric vehicle turns or is affected by wind, thus maintaining the stability of the canopy structure.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown in Figure 7, a crossbar connecting device for an electric vehicle canopy bracket includes two sets of identical brackets symmetrically arranged on the left and right sides and several crossbars 3. The brackets are composed of several sets of cross-connected rods. Each set of cross-connecting rods includes a first connecting rod 1 and a second connecting rod 2. In each set of cross-connecting rods, the tail end of the first connecting rod 1 is hinged to the front end of the second connecting rod 2 of the next adjacent set, and the tail end of the second connecting rod 2 is hinged to the front end of the first connecting rod 1 of the next adjacent set. The middle of the cross-connecting rods is movably hinged. A notch 101 is provided on the outer side of the upper hinge point of the cross-connecting rods. The notch 101 is used to movably engage the crossbars 3. The notch 101 is a C-shaped opening. In specific implementation, the upper, middle, and lower parts of the first connecting rod 1 and the second connecting rod 2 are respectively provided with connecting holes 4 of equal diameter that are interconnected. The cross-connecting rods are movably hinged by rivets or bolts passing through the connecting holes 4, which facilitates linkage folding and unfolding, and occupies a small volume after folding. In this embodiment, the symmetrical support is connected above a waterproof cloth 5 to form a rain shelter. The front end of the waterproof cloth 5 is fixedly or movably connected to the upper end of the front transparent panel 8. The front transparent panel 8 is fixedly installed on the front support 7 by screws. Several sets of sleeves or sleeve-shaped connecting pieces 6 with inward openings are symmetrically sewn on both sides of the waterproof cloth 5. When the rain shelter is fully extended, the sleeves of the connecting pieces 6 and the notches 101 are on the same straight line. The horizontal bar 3 is connected and fixed to the waterproof cloth 5 by fitting both ends of the horizontal bar 3 into the sleeves of the connecting pieces 6. The horizontal bar 3 is used to connect the cross link to the waterproof cloth 5, which serves to fix the waterproof cloth 5. At the same time, it can support and keep the waterproof cloth 5 taut in the horizontal and vertical directions, preventing the waterproof cloth 5 from wrinkling and accumulating rainwater, which would cause the roof to collapse, thus increasing the stability of the rain shelter structure. After the crossbar 3 is connected and fixed to the waterproof cloth 5, when further installing the crossbar 3, simply press the crossbar 3 directly to make the C-shaped notch 101 open elastically and snap into the notch 101, thus achieving the connection between the crossbar 3 and the cross link. This overcomes the troublesome installation of the existing circular hole connection, which requires disassembling the crossbar and the high installation difficulty for users. This utility model is easy to install and disassemble, has a simple structure, and when packing and shipping, the waterproof cloth 5 with the crossbar 3 is easy to pack separately from the bracket, which greatly reduces the size of the packing box and the express delivery cost, and can reduce the risk of damage to the bracket or the waterproof cloth 5.

[0023] The entrance width of the notch 101 is slightly smaller than the outer diameter of the crossbar 3 to prevent the crossbar 3 from easily coming out of the notch 101 due to the pulling force when the front of the vehicle turns after it is installed in the notch 101.

[0024] The notch 101 is located at the top of the first connecting rod 1 and is integral with the first connecting rod 1. The first connecting rod 1 and the notch 101 are integrally molded using injection molding, which simplifies the process and increases the strength and stability of the notch 101. In this embodiment, the lower outer surface of the entrance of the C-shaped notch 101 is set as a slope. Utilizing the guiding principle of the slope, it is convenient for the crossbar 3 to be inserted into the notch 101 along the slope, making installation simpler and faster, both visually and blindly.

[0025] With the transverse centerline of the notch 101 as the reference line c, the opening of the notch 101 faces diagonally downwards from the reference line c, and the reference line c is perpendicular to the longitudinal direction of the first connecting rod 1. Due to wind resistance and airflow during the electric vehicle's operation, the waterproof cloth 5 will cause the crossbar 3 to move up and down with the wind, subjecting the crossbar 3 to vertical pulling forces. Especially when the vehicle turns, it will cause the support frame to twist, making it easy for the crossbar 3 to forcibly detach from the notch 101. When the crossbar 3 detaches from the notch 101 under these conditions, the waterproof cloth 5 will separate from the support frame, causing the entire canopy structure to collapse and compromising its stability. Setting the opening of the notch 101 in an inclined shape allows the crossbar 3 to act as a barrier when subjected to vertical and lateral forces, effectively preventing the crossbar 3 from easily detaching from the notch 101 under external force.

[0026] A locking plate 201 is provided at the top of the second connecting rod 2. The height of the locking plate 201 is sufficient to seal more than a portion of the notch 101 until the crossbar 3 cannot be dislodged. The locking plate 201 moves in an arc as the connecting rod unfolds or retracts, and its trajectory dynamically interferes with the opening area of ​​the notch 101. In this technical solution, the height of the locking plate 201 is set to different heights depending on the height position of the notch 101. This ensures that when the cross connecting rod is in the retracted state, the locking plate 201 can both seal the notch 101 so that the crossbar 3 cannot be dislodged even if external force is encountered, and also prevent the locking plate 201 from pressing the crossbar 3 upwards in the longitudinal direction of the second connecting rod 2, causing the crossbar 3 to be deformed or broken under pressure, and avoid contact friction with the crossbar 3, which would affect the flexibility of the cross connecting rod's unfolding and retraction. As the first link 1 and the second link 2 unfold and retract, the overlapping portion of the locking plate 201 and the opening of the notch 101 forms a dynamically openable and closable structure. When the first link 1 and the second link 2 are in the retracted state, the locking plate 201 effectively seals the notch 101, preventing the crossbar 3 from coming out. When the first link 1 and the second link 2 unfold from the retracted state until the side of the second link 2 is parallel to the lower inclined surface outside the entrance of the notch 101, the locking plate 201 leaves the opening of the C-shaped notch 101, thus fully opening the notch 101. At this time, the crossbar 3 can be inserted into the notch 101 or removed from the notch 101, achieving quick assembly and disassembly of the crossbar 3. The operation is convenient and fast. When the first link 1 and the second link 2 continue to unfold, the side of the second link 2 gradually seals the notch 101, preventing the crossbar 3 from coming out. This creates a dynamically openable and closable structure, ensuring that the crossbar 3 is always sealed within the notch 101 and will not detach from it, greatly increasing the stability of the awning structure and the ease of installation of the crossbar 3. It should be noted that the locking plate 201 leaving the C-shaped notch 101 is only a momentary state during the process of the cross link moving from retraction to extension or vice versa. In this state, the crossbar 3 is only subjected to a slight pulling force generated when the waterproof cloth 5 extends or retracts along with the link. This pulling force is less than the elastic tension required to expand the notch 101 when the crossbar 3 detaches. Therefore, the crossbar 3 will never detach from the notch 101. Furthermore, in the normal retraction or extension state of the awning, the locking plate 201 or the side of the second link 2 can always seal the crossbar 3, preventing it from detaching from the notch 101.

[0027] In this technical solution, the front end of the first group of cross links is movably hinged to the first fulcrum 701 and the second fulcrum 702 provided on the upper part of the canopy front support 7. The second link b203 of the last group of cross links is shorter than the first link a103, and the tail end of the second link b203 is movably hinged to the middle of the first link a103. In specific implementation, the front end of the first link A102 of the first group of links is movably hinged to the first fulcrum 701, and the first link A102 is set in two segments, the front segment 1021 and the rear segment 1022 are movably hinged by rivets or bolts. The front end of the second link B202 is movably hinged to the second fulcrum 702. This arrangement can realize the linkage of the cross links in retraction and expansion within the shorter fulcrum range where the first fulcrum 701 and the second fulcrum 702 are fixed. A second crossbar 9 is installed at the tail of the first connecting rod a103 in the last group of connecting rods. A corner connector is used at the tail of the first connecting rod a103 to attach the end of the second crossbar 9, thus connecting and fixing the second crossbar 9 to the tail of the first connecting rod a103. A transverse culvert is installed at the tail of the waterproof fabric 5 to wrap and fix the second crossbar 9. The second crossbar 9 controls the distance between the two side supports and keeps the tail of the waterproof fabric 5 taut, reinforcing the overall structure of the awning. In this technical solution, the length of all connecting rods and the position of the hinge points have been precisely designed and calculated to ensure that the supports conform to the overall shape of the awning when unfolded and that each connecting rod can be closed to its minimum volume when retracted. Errors in the length of any single connecting rod will not cause the awning to not fit properly when retracted or to deviate from the designed shape when unfolded.
