Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a front windshield device, an electric vehicle and a mold for processing the front windshield. Background Art

[0002] Electric vehicles are a common means of transportation, typically two or three wheels, and are widely used in urban areas. However, riding an electric vehicle can be difficult in rainy, windy, or sunny conditions. Installing a front windshield and roof can alleviate this problem.

[0003] Existing electric vehicles or motorcycles generally have two structures of front windshields. One of them is shown in the Chinese patent No. 201922316378.3. The transparent front windshield has a hole directly opened at the lower part and is fixed to the mounting rod installed on the front of the vehicle by screws. Although this front windshield does not seriously affect the rider's field of vision, the front windshield is small and the windshield effect is poor. The support points are concentrated in the lower part of the front windshield, and the upper end of the front windshield is prone to swinging. The connection strength is weak, and the screws protrude from the surface of the front windshield. If a wiper is installed, the swing range of the wiper is limited by the screws, the swing range is small, and the field of vision on rainy days cannot be guaranteed.

[0004] Another structure, as shown in Chinese patent number 201811046649.1, creates a groove in the middle of an opaque frame, then secures a transparent sheet within the groove. Finally, holes are drilled in the transparent sheet and the edges of the groove, allowing connectors to secure the piece. This arrangement has the following disadvantages: 1. The opaque frame restricts the rider's field of vision; 2. Installation is cumbersome; 3. When windshield wipers are installed, the connectors protruding from the edge of the transparent plate restrict the wipers' swing range, affecting vision on rainy days. Simply increasing the size of the frame and groove would increase the overall size of the electric vehicle, making it very bulky. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the first purpose of the present invention is to provide a front windshield device that is easy to produce and install, has good structural strength, and does not affect the rider's field of vision and the swing range of the wiper.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a front windshield device, including a front windshield and front support rods arranged on the left and right sides of the front windshield, the lower end of the front support rods is connected to the vehicle body, the front windshield includes an injection-molded transparent plate body, and a connecting column for connecting to the front support rods is provided on the left and right sides of the back of the plate body. The connecting column and the plate body are injection-molded as a whole. The connecting column protrudes from the back of the plate body. A reinforcement connected to the side of the connecting column is provided on the outside of the connecting column. The reinforcement is injection-molded as a whole with the connecting column, and also includes a connecting component for fixing the front support rod on the connecting column.

[0007] Through this technical solution, the entire front windshield is injection-molded from a transparent material. Only the front struts slightly obstruct the view, leaving both the inside and outside of the struts visible without affecting the rider's field of vision. Furthermore, this one-piece injection molding process facilitates processing and provides superior overall structural strength. Compared to existing transparent windshields made by hot-bending plexiglass, this offers improved structural strength, lighter weight, and greater ease of production. It can also be manufactured in larger volumes and more complex shapes at a lower cost.

[0008] Connecting posts are located on the back of the panel, and the front struts can be secured to the connecting posts via connectors. The connecting posts are located on both sides of the panel. Once the front struts are secured, they are positioned on either side of the panel, preventing the rider from obstructing their field of vision. The provision of the connecting posts eliminates the need for screws or other devices to penetrate the panel during installation, resulting in a smooth curved or flat surface on the front of the windshield without protrusions. This eliminates the need for obstructions on the windshield's front surface, ensuring smooth wiper operation and ensuring the rider's field of vision in rainy weather.

[0009] When the front support rod and the connecting piece are connected, the front support rod can be directly fixed on the connecting column through one connecting piece, or the front support rod can be fixed between multiple connecting columns through the cooperation of multiple connecting pieces.

[0010] The connecting member may be a screw or pin, which passes through the front strut and the connecting seat to secure the front strut to the connecting post. The connecting post may also be provided with a threaded post, which passes through a hole in the front strut. The front strut is then secured to the connecting post using a nut or other connecting member. The threaded post may be integrally injection molded with the connecting post, or a threaded rod or screw may be embedded within the connecting post, with the threaded section of the threaded rod or screw extending beyond the connecting post.

[0011] The front windshield is large and heavy, so it's subject to significant vibrations during driving. The connecting column connects the front windshield and front struts, which can be subject to significant impact. Reinforcements are installed on the outside of the connecting column to strengthen its structure and prevent damage from significant impact during driving.

[0012] Preferably, the reinforcement includes a panel, which surrounds the outside of the connecting column and is connected to the connecting column; or the reinforcement includes a reinforcing rib, which is connected to the outer side of the connecting column; or the reinforcement includes a panel and a reinforcing rib, which surrounds the outside of the connecting column, and the two ends of the reinforcing rib are respectively connected to the panel and the side of the connecting column.

[0013] The above technical solution provides a certain degree of structural strength for the panels and reinforcements. When connected to the connecting column, the panels eliminate the need for support from the connecting column, preventing the connecting column from being subjected to significant impact and potentially breaking. Furthermore, the installation of the panels and reinforcements increases the effective contact area between the connecting column and the panel, dispersing the impact force on the connecting column, thereby reducing the impact force per unit area and preventing cracking at the connection between the connecting column and the panel. The panels can be partially connected to the connecting column by wrapping around the outside of the connecting column, or they can be connected to the column via reinforcements.

[0014] Preferably, a plurality of connecting seats are provided on the back of the plate body, and the connecting seats include two connecting columns, which are arranged at intervals, and a limiting portion for limiting the front support rod is provided between the two connecting columns, and also includes a clamp and / or cover plate for pressing and fixing the front support rod in the limiting portion.

[0015] Through the above technical solution, a connecting seat includes two connecting columns and reinforcements on the outside of the two connecting columns. The front strut is fixed between the two connecting columns. The two connecting columns simultaneously connect and fix one part of the front strut, making the connection between the front strut and the front windshield more secure.

[0016] The positioning portion can accurately locate the front strut, ensuring installation accuracy and preventing the front strut from shaking between the two connecting columns. The clamp or cover can easily press the front strut against the positioning portion in the connecting seat, effectively securing the front strut.

[0017] Preferably, a circle of panels surrounds the outer sides of the two connecting columns, a plurality of reinforcing ribs are connected between the panels and the connecting columns, and the limiting portion is arranged on the panels between the two connecting columns.

[0018] The above technical solution allows the enclosure to wrap around the outside of the connecting column and form an integrated structure, which has good overall rigidity and deformation resistance. The connecting column is connected to the enclosure via reinforcing ribs. When the connecting column is stressed, part of the load can be transferred to the enclosure, preventing the connecting column from breaking under increased load. This further strengthens the structural strength of the connecting column and ensures reliability during use. The enclosure is circular, connected end to end, and can have a rectangular or elliptical cross-section.

[0019] Preferably, a panel is provided on the outside of each of the two connecting columns. The panel is C-shaped and surrounds the outside of the connecting column. A limiting member is provided between the two panels, and the limiting portion is provided on the limiting member.

[0020] The above technical solution eliminates the need for a separate panel on the outer sides of the two connecting posts. This allows the area between the two posts to be separated into two separate, spaced-apart sections. The two separate sections still wrap around the outer sides of each connecting post. The front strut's position is then determined by installing an additional stopper with a stopper portion provided on the stopper.

[0021] The enclosure is divided into two parts, creating two independent molding cavities during injection molding. Each cavity is smaller, allowing the molten plastic to expel air from the cavity and fill it. Removing the enclosure between the two connecting columns also prevents air from mixing with the molten plastic during injection molding, which can form bubbles in the product.

[0022] During injection molding, the molten plastic enters the molding cavity from the injection port, diffuses to the surrounding areas along the plate cavity, and gradually expel the air in the original cavity as the plastic is filled in, preventing the air from mixing into the molten plastic and forming bubbles inside the product. The existence of the cavity forming the connection seat will affect the filling speed in the direction from the injection port to the cavity line. If the cavity forming the connection seat is large, the cavity filling speed at the connection seat will be slower and take longer, while the filling speed on both sides of the cavity will be faster. The molten plastic on both sides of the cavity will form a backfill on the cavity from the back side of the cavity, and the plate part outside the connection seat will be filled with molten plastic when the cavity forming the connecting column and the enclosure is not fully filled. As a result, some of the air remaining in the cavity forming the connection seat is enclosed in the molten plastic, resulting in bubbles inside the product after the injection molding is completed. At the same time, there is a long distance between the two connecting columns. If it is an integrated structure, the length of the enclosure between the two connecting columns is also long. The horizontal cavity on the mold will cause a greater obstruction to the flow of the molten plastic at this location, affecting the flow of the molten plastic in this direction, making it easier for the plastic on both sides of the connecting seat to form a backpacking there, causing air to be mixed in the molten plastic.

[0023] The spaced-apart panels eliminate the need for a panel between the two connecting columns. This reduces the volume of the cavity, facilitating venting and filling. Furthermore, the mold's long grooves prevent the molten plastic from flowing through this area, hindering its flow in that direction. Separating the stoppers from the plate and connecting columns also simplifies the mold structure, reduces machining effort, and facilitates fabrication.

[0024] Preferably, the limiting member is a hoop, which is placed between the two connecting columns with its opening facing the outside of the plate; or the limiting member is engaged between the two connecting columns with the limiting portion being arranged at the outer end of the limiting member.

[0025] With the above technical solution, the limiter is provided separately, which can also achieve the positioning of the front strut more conveniently. When using the clamp, the clamp is inverted on the connecting column, with the clamp opening facing the outside of the plate body. The clamp opening is the limit part, which can be used to remember the position of the front strut. The two ends of the clamp are placed on the connecting column. The screw passes through the cover plate or another clamp that presses the front strut and passes through the clamp at the same time, thereby fixing the front strut.

[0026] Alternatively, a separate retaining member can be provided that fits between the two connecting posts, with a retaining groove defined at the end of the retaining member facing away from the board to position the front strut. The retaining member's inner end contacts the board surface, while its left and right ends each contact a connecting post. This allows some of the impact force from the front strut to be transferred directly to the board, reducing the impact on the connecting posts. Furthermore, the retaining member, positioned between the two connecting posts, prevents them from bending, better defines their position, and enhances their overall structural strength.

[0027] Preferably, the lower end of the front support rod is bent toward the middle of the plate body, and the outer end of the connecting seat close to the lower end of the plate body is inclined toward the lower part of the plate body.

[0028] Through the above technical solution, the front strut can be connected to the frame more conveniently. Generally speaking, the connection strength is the highest when the front strut is directly connected to the frame. The frame is generally located in the middle of the front of the vehicle, and the lower end of the corresponding front strut needs to be retracted inward. The inclination of the connecting seat can better cooperate with the structure of the lower end of the front strut for firm fixation.

[0029] Preferably, the two front support rods are bent, and the number of connecting seats is at least two pairs. The same pair of connecting seats are respectively arranged on the left and right sides in the width direction of the plate to form a row, and the distances between the left and right connecting seats in two adjacent rows of connecting seats are different.

[0030] Through the above technical solution, the bending setting of the front strut can avoid the middle area of ​​the front windshield to avoid affecting the line of sight. The same pair of connecting seats are respectively arranged on the left and right sides of the width direction of the plate to form a row, which can stably fix the edges of both sides of the plate to the front strut. The lower part of the front strut needs to be connected to the frame, so it needs to be retracted inward. In order to avoid blocking the line of sight, the upper part of the front strut needs to be opened outward, resulting in different distances at different parts of the front strut. The distances between the two connecting seats in two adjacent rows are different. On the one hand, it can adapt to the shape of the front strut. On the other hand, it can avoid the plate from sliding along the length direction of the front strut after the front strut and the connecting seat are connected, which affects the stability of the connection and makes the installation more stable.

[0031] Preferably, lamps or reflective devices are provided on the left and right sides of the plate.

[0032] Through the above technical solution, the lamps and reflectors are installed on the left and right sides of the board, which are higher than those installed above the wheels, making them easier to observe. At the same time, the distance between the two lamps can be larger, making them easier to distinguish.

[0033] Preferably, the injection port during injection molding of the front windshield is located in the middle of the width direction of the plate body, and the flow from the injection port to the top or bottom of the plate body accounts for 15-25% of the total flow.

[0034] With the above technical solution, the sprue will leave a mark on the windshield during injection molding, forming an injection port. If the injection port is located in the middle of the windshield, it will obstruct vision. If the injection port is too close to the top or bottom of the panel, the injection pressure will be too high during injection, causing the molten plastic to squeeze out of the edge of the mold cavity on the side near the sprue, forming flash, while the side away from the sprue will not be completely filled with molten plastic. When the injection port is within this range, the above problems can be effectively avoided. The distance that the molten plastic flows from the injection port to the top or bottom of the panel is the flow rate from the injection port to the top edge of the panel. The total flow rate is the sum of the distance the plastic flows from the injection port to the top and the distance it flows from the injection port to the bottom.

[0035] Another object of the present invention is to provide a mold for processing the above-mentioned front windshield, including a movable mold and a fixed mold, a molding cavity is formed between the movable mold and the fixed mold, and a pouring gate is arranged in the middle of the molding cavity along the width direction of the front windshield, and the flow from the pouring gate to the bottom or top of the molding cavity is 15~25% of the total flow.

[0036] Through the above technical solution, during injection molding, the plastic can better fill the molding cavity without generating flash, and the pouring port can avoid the middle area of ​​the front windshield, avoiding leaving the injection port in the middle area of ​​the front windshield to block the line of sight during use.

[0037] The third object of the present invention is to provide an electric vehicle, comprising a vehicle body and the above-mentioned front windshield device, and also comprising a roof, a rear support rod and a cover plate, wherein a fixing seat 1 is provided at the upper end of the front windshield, a fixing seat 2 corresponding to the fixing seat 1 is provided at the front end of the roof, the front end of the cover plate is fixedly connected to the fixing seat 1, and the rear end of the cover plate is fixedly connected to the fixing seat 2, the upper end of the front support rod extends into the fixing seat 2, and a protrusion that is snapped into the front support rod is provided on the fixing seat 2 or the cover plate, and a groove or a snap hole that cooperates with the snap block is provided on the front support rod, the lower end of the rear support rod is connected to the rear of the vehicle body, and the upper end of the rear support rod is connected to the rear of the roof.

[0038] Through the above technical solution, the front windshield can be fixed to the electric vehicle more conveniently to block the wind generated during driving. At the same time, since the front windshield is only fixed by two front support rods, there will be only a little obstruction at the front support rods, and the field of view outside the front windshield is not blocked, the overall field of view is better, and driving is safer. The cover plate can more conveniently connect the front windshield and the roof together to achieve fixation between the two. At the same time, the upper end of the front support rod extends into the fixing seat, which can directly support the front end of the roof. At the same time, a rear support rod is provided at the rear end of the roof to support the rear end of the roof. A protrusion is provided in the cover plate or the second fixing seat, and the protrusion can be snapped into the groove or the clamping hole on the front support rod, so that there is no relative sliding between the front support rod and the second fixing seat or the cover plate, and the connection is more firm.

[0039] Preferably, a transverse reinforcing rib is provided at the front end of the ceiling along the width direction, and the transverse reinforcing rib is located on the outer surface of the upper portion of the second fixing seat and / or the transverse reinforcing rib is located between the second fixing seats.

[0040] Through the above technical solution, the transverse reinforcement ribs are provided at this location to strengthen the overall structure of the front end of the ceiling. The front end of the ceiling is connected to the ceiling and the front support rod through the second fixing seat to provide support. The force on the second fixing seat is relatively concentrated, and cracking is likely to occur between the connecting seat and the entire board surface of the ceiling during use. The provision of transverse reinforcement ribs can disperse the force, making the force on the front end of the board more uniform, and avoiding cracking between the ceiling and the board surface. At the same time, transverse reinforcement ribs can be provided above the connecting column on the fixing seat to increase the thickness of this location to prevent the ceiling from being pierced during screw installation.

[0041] Preferably, the transverse cross-section of the roof is wavy, and the left and right edges of the roof and / or the front windshield are bent outwards to form a water retaining edge.

[0042] Through the above technical solution, the transverse cross-section of the roof is wavy, so that the roof surface is not flat, but has spaced protrusions or depressions. The protrusions or depressions can act like reinforcing ribs, enhancing the overall structural strength of the roof. The protrusions or depressions can be arc-shaped or approximately trapezoidal in shape. The left and right edges of the roof and front windshield are bent outward to form a water retaining edge. The water retaining edge can not only strengthen the position structure of the front windshield and roof edges, but also prevent the edges from cracking and damage. On the other hand, it can also guide rainwater so that it flows forward or backward along the water retaining edge, preventing rainwater from flowing out of the sides of the roof or front windshield and dripping onto the rider.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows: by directly providing a connecting column on the back of the front windshield, the front windshield and the front strut can be fixed directly through a connecting piece, without the need to provide a through hole in the front windshield, and the use of a connecting piece to fix the front windshield will not cause a bulge on the front of the front windshield, thereby affecting the swing of the wiper. The front windshield is supported by a thinner front strut, which is located on the left and right sides of the front windshield, resulting in less obstruction to the field of vision. Only the front strut will produce less obstruction, and the inside and outside of the front strut are both visible areas. Compared with the fixing method of installing the front windshield in an opaque frame, the field of vision is wider. The reinforcement member is provided on the outside of the connecting column, which can effectively enhance the ability of the connecting column to withstand impact and ensure structural strength.

DETAILED DESCRIPTION

[0067] The present invention will be further described in detail below with reference to the accompanying drawings.

[0068] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0069] Example 1: A front windshield device

[0070] like Figure 1 As shown, a front windshield device includes a front windshield 15 and a front strut 14, the lower end of which is connected to the vehicle body. The front windshield 15 comprises an injection-molded transparent plate 1. Multiple connecting posts 2 are provided on the left and right sides of the back of the plate 1 for connecting to the front strut 14. The connecting posts 2 protrude from the back of the plate 1. Reinforcements 32 are provided on the outside of the connecting posts 2. The reinforcements 32 are connected to the sides of the connecting posts 2 and are integrally injection-molded with the plate 1.

[0071] The reinforcement 32 includes a panel 4, which is connected to the connecting column 2. The panel 4 can completely surround the connecting column 2 or partially surround the connecting column 2. In this embodiment, the panel 4 is C-shaped and partially surrounds the outside of the connecting column 2. The openings of the panel 4 on the outside of the two connecting columns 2 are arranged opposite to each other. The openings of the panel 4 are arranged facing each other, so that there is a larger space between the two connecting columns 2 for placing the limiter 6. The panel 4 can be directly connected to the connecting column 2, or it can be connected to the connecting column 2 through the reinforcement rib 3, thereby improving the structural strength of the connecting column 2. In this embodiment, the reinforcement rib 3 is used to connect the two. In addition, the reinforcement rib 3 can also be separately set on the outside of the connecting column 2 to strengthen the structure of the connecting column 2.

[0072] like Figures 2 to 5 As shown, a plurality of connecting seats 5 are provided on the back of the plate body 1. The connecting seats 5 include two connecting columns 2 and reinforcement members 32 connected to the connecting columns 2. The two connecting columns 2 are spaced apart, and the enclosure 4 on the outside of the two connecting columns 2 is also spaced apart. A limiting member 6 is installed between the two connecting columns 2. The limiting member 6 and the plate body 1 are separated. The upper end of the limiting member 6 is provided with a limiting portion 7 for limiting the position of the front support rod 14. Slots 8 are provided on both sides of the limiting member 6 to cooperate with the outer surface of the connecting column 2. The limiting member 6 is fixed between the two connecting columns 2 through the slots 8, so that the position of the limiting member 6 is effectively positioned. The bottom of the limiting member 6 contacts the back of the plate body 1, and the two ends contact one connecting column 2 respectively. The front support rod 14 is engaged in the limiting portion 7 to position the front support rod 14.

[0073] The lower end of the front support rod 14 is bent inward, and multiple pairs of connecting seats 5 are provided on the back of the plate body 1. The outer ends of the connecting seats 5 near the lower end of the plate body 1 are inclined toward the lower part of the plate body 1, so that the connecting seats 5 can cooperate with the lower ends of the front support rod 14 that are retracted inward, corresponding to the structure of the front support rod 14, so that the connection between the connecting seats 5 and the front support rod 14 can be more fitting and firm.

[0074] The front struts 14 are bent as a whole, and the two front struts 14 are not parallel to each other. At least two pairs of connecting seats 5 are provided along the height direction of the plate body 1, and the same pair of connecting seats 5 are provided on the left and right sides of the width direction of the plate body 1, forming a row. The distance between the two connecting seats 5 in the lower row is greater or less than the distance between the two connecting seats 5 in the upper row. This arrangement allows the connecting seats 5 to be consistent with the structure of the front struts 14. At the same time, after the front windshield 15 is fixed to the front struts 14, the different spacing between the upper and lower groups of connecting seats 5 prevents up and down sliding, and the connection between the front struts 14 and the connecting seats 5 is more stable and firm after being fixed.

[0075] The connecting member 31 also includes a clamp 16 or a cover plate 17, which is located at the outer end of the connecting column 2. The clamp 16 or the cover plate 17 is provided with a receiving groove for accommodating the front support rod 14, and the receiving groove faces the plate body 1. The clamp 16 or the cover plate 17 is fixed to the connecting column 2 by screws, and the front support rod 14 is clamped between the limit member 6 and the clamp 16 or the cover plate 17 to achieve fixation of the front support rod 14.

[0076] Example 2: A front windshield

[0077] like Figures 6-8 As shown, the main difference between Example 2 and Example 1 is that in Example 2, a circle of panels 4 surrounds the outside of the two connecting columns 2. The panels 4 are an integral structure with a roughly rectangular cross-section. The panels 4 surround the outside of the two adjacent connecting columns 2 as a whole. The panels 4 on the outside of the two connecting columns 2 are butted together to form a single body. The panels 4 and the connecting columns 2 are connected by multiple reinforcing ribs 3. The two connecting columns 2 and the panels 4 on the outside together form a connecting seat 5. A stopper 7 is provided on the panel 4 between the two connecting columns 2 for contacting the outer surface of the front support rod 14. The panels 4 of the two connecting columns 2 are integrally injection molded with the plate body 1, which increases the overall structural strength of the connecting seat 5 and makes the overall structure more stable after installation.

[0078] At the same time, the front windshield 15 still has an injection port 10 left during the injection molding process. The injection port 10 is located in the middle of the width of the plate body 1. The injection port 10 is the trace left on the plate body by the pouring gate during the injection molding process. The flow from the injection port 10 to the bottom of the plate body 1 is between 15% and 25% of the total flow, and in this embodiment, it is selected to be 18%. When the injection port 10 is in this position, it can avoid the injection port 10 being located in the middle of the plate body 1 and affecting the rider's field of vision. At the same time, this position is not too close to the lower end of the plate body 1, so that the lower end of the mold will not be subjected to excessive pressure during injection molding, which would cause the molten plastic to be squeezed out from the lower edge of the mold due to excessive injection pressure to form flash. At the same time, it can also ensure that the cavity at the top of the mold is completely filled with molten plastic, ensuring the quality of injection molding.

[0079] In addition, lamps 9 or reflectors 28 are mounted on the left and right edges of the panel 1. These lamps 9 and reflectors 28 are both relatively small and lightweight, and can be secured by opening small through-holes in the edge of the panel 1 and then securing them with screws. Because these holes are located at the edge of the panel 1, the wipers will not swing to this position, so even using screws to secure them does not restrict the wiper's swing angle. The lamps 9 and reflectors 28 can also be secured to the edge of the panel 1 by clamping them together. Clamping blocks are provided on the lamps, which clamp onto the edge of the panel 1.

[0080] Embodiment 3, a front windshield,

[0081] like Figures 9-11 As shown, the main difference between the third embodiment and the first embodiment is that the limiting member 6 between the two connecting columns 2 in the third embodiment is a clamp 16, and the connecting seat 5 is only composed of two connecting columns 2 and the outer panels 4 and the reinforcing ribs 3. The panels of the two connecting columns 2 are spaced apart. A clamp 16 is placed on the connecting column 2, and the opening of the clamp 16 faces the outer side of the plate body 1. When installing the front support rod 14, as shown in FIG. Figure 9 As shown, two clamps 16 are used to clamp the front strut 14, and then two screws are used as connecting parts 31 to fix the two ends of the two clamps 16 on the two connecting columns 2. The two clamps 16 clamp the front strut 14 to fix the front strut 14.

[0082] Example 4: A mold for processing a front windshield

[0083] like Figure 12 As shown, a mold for processing a front windshield includes a movable mold 11 and a fixed mold 12, and the movable mold 11 and the fixed mold 12 cooperate to form a molding cavity 13 with the same shape of the front windshield. The pouring gate 26 is arranged in the middle of the molding cavity 13 along the width direction of the front windshield 15. The pouring gate 26 is arranged in the middle of the width direction of the front windshield, and the left and right sides of the front windshield 15 can be injection molded more evenly. The flow from the pouring gate 26 to the bottom or top of the molding cavity 13 is 10-25% of the overall flow of the molding cavity 13. The height selected in this embodiment is 19% of the overall flow of the molding cavity 13. The pouring gate 26 is arranged at this location to avoid the area in the middle of the front windshield, so as to avoid the injection gate 10 being left in the middle of the front windshield after injection molding when the pouring gate 26 is in the middle of the molding cavity 13, affecting the line of sight. At the same time, if the pouring gate 26 is too close to the bottom of the plate body 1, the bottom of the molding cavity 13 may be easily squeezed out from the bottom edge of the mold due to excessive pressure during injection, forming flash. At the same time, it also prevents the top of the molding cavity 13 from being unable to be filled with plastic due to insufficient injection pressure, affecting the quality of the finished product.

[0084] Example 5: An electric vehicle

[0085] like Figures 13 to 22As shown, an electric vehicle includes a vehicle body (not shown), a front support rod 14 and the front windshield device of Example 1, the upper end of the front windshield 15 is connected to the roof 18, the upper end of the front windshield 15 is provided with a fixing seat 1 20, the front end of the roof 18 is provided with a fixing seat 21, and a cover plate 17 is installed on the fixing seat 1 20 and the fixing seat 2. The front end of the cover plate 17 is fixed to the fixing seat 1 20 by screws, and the rear end of the cover plate 17 is fixed to the fixing seat 21 by screws. The front struts 14 extend from the left and right sides of the front windshield 15 to the second fixing seat 21. The cover plate 17 is provided with a protrusion 23 protruding in the direction of the front strut 14. The protrusion 23 is arc-shaped. The upper end of the front strut 14 is provided with a groove 24 that cooperates with the protrusion 23. The groove 24 is also arc-shaped. The protrusion 23 is stuck in the groove 24, so that the front windshield 15, the front struts 14 and the roof 18 are all connected to the cover plate 17 as a whole. The cover plate 17 can fix the relative positions of the three at the same time, and the connection is more convenient and stable.

[0086] like Figure 17 and 18 As shown, the protrusion 23 can also be set in the fixing seat 21 at the front end of the ceiling 18. The protrusion 23 is cylindrical, and a card hole 25 for inserting the cylindrical protrusion 23 is opened at the upper end of the front support rod 14. The card hole 25 passes through the front support rod 14.

[0087] like Figure 19 and Figure 20 As shown, the front end of the roof 18 is provided with two transverse reinforcing ribs 29, one of which is located between the two fixing seats 21 on the inner side of the roof 18. The two ends of the transverse reinforcing rib 29 are respectively connected to the fixing seat 21, thereby enhancing the structural strength of this area and preventing cracking between the plate surface of the connecting seat 5 and the fixing seat 21 due to repeated bumps during use. At the same time, transverse reinforcing ribs 29 are also provided on the outer side of the roof 18, located above the connecting column 2 of the connecting seat 5. On the one hand, these transverse reinforcing ribs 29 enhance the structural strength of this area, and on the other hand, they increase the thickness of this area, thereby preventing the screws from piercing the roof 18 when connecting to the cover plate 17.

[0088] In addition, if Figure 21 As shown, the transverse cross section of the ceiling 18 is wavy, so that the surface of the ceiling 18 is not flat, but has spaced protrusions or depressions. The protrusions or depressions extend along the length of the ceiling 18, forming a similar effect to the reinforcement ribs 3, thereby enhancing the overall structural strength of the ceiling 18. The protrusions or depressions can be arc-shaped or approximately trapezoidal. Figure 22As shown, the left and right edges of the roof 18 and the front windshield 15 are bent outward to form a water retaining edge 30. On the one hand, the water retaining edge 30 can strengthen the position structure of the edges of the front windshield 15 and the roof 18 to prevent the edges from cracking and damaging; on the other hand, it can also guide rainwater to flow forward or backward along the water retaining edge 30, thereby preventing or reducing rainwater from flowing out from both sides of the roof 18 and the front windshield 15 and dripping or flying onto the rider.

[0089] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
