Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, and particularly relates to a front and rear adjustable seat structure for an electric vehicle. Background Art

[0002] An electric vehicle is a pure electric motor vehicle powered by a battery and driven by a motor. It has the advantages of environmental protection, convenient use, strong flexibility, low price, etc. Electric vehicles have become an important means of transportation for people to go out daily. In the prior art, the seats of electric vehicles are generally fixed and non-adjustable. If the vehicle is selected according to the average height, for users with too high height, the distance between the seat and the handlebar is short, and for users with too short height, it is long. When such users use the electric vehicle, the riding posture is relatively uncomfortable. In order to use it more comfortably, people with higher height can only choose larger vehicles, and people with shorter height can only choose smaller vehicles. This leads to a situation where a family needs to purchase multiple vehicles, or choose to buy one vehicle mainly based on one person. Buying multiple vehicles will increase the family's financial investment and also occupy more parking space. While choosing one vehicle, it will not be very comfortable for others to use, which reduces the functionality and practicality of the electric vehicle. Therefore, it is very necessary to propose a front and rear adjustable seat structure for an electric vehicle to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a front and rear adjustable seat structure for an electric vehicle, so as to solve the problems that choosing multiple electric vehicles will increase the family's financial investment and also occupy more parking space, while choosing one vehicle, it will not be very comfortable for others to use, reducing the functionality and practicality of the electric vehicle.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A front and rear adjustable seat structure for an electric vehicle, including a track frame installed on the vehicle frame. One end of the track frame is hinged to the vehicle frame, and the other end of the track frame is connected to the vehicle frame through a mechanical lock. Four convex sliding seats are slidably installed on the track frame, and the same seat board is fixedly installed on the four convex sliding seats. A first locking bolt is threadedly connected to one of the convex sliding seats, and the first locking bolt is arranged in cooperation with the track frame;

[0005] Two U-shaped sliding seats are slidably installed on the track frame. A shaft rod is rotatably installed on the U-shaped sliding seat. The same mounting frame is fixedly installed on the two shaft rods, and a backrest is arranged on the mounting frame.

[0006] Preferably, a second locking bolt is threadedly connected to one of the U-shaped sliding seats, and the second locking bolt penetrates through the U-shaped sliding seat. The second locking bolt is arranged in cooperation with the track frame.

[0007] Preferably, cross plates are fixedly installed on both sides of the top track frame of the vehicle frame. Square plates are fixedly installed on both shaft rods, and the lower surface of the square plate is in movable contact with the upper surface of the cross plate.

[0008] Preferably, square grooves are formed on both sides of the track frame. The first locking bolt passes through one of the square grooves and is threadedly connected to the convex slide seat, and the diameter of the tail end of the first locking bolt is greater than the height of the square groove.

[0009] Preferably, one end of the U-shaped slide seat is slidably installed inside the corresponding square groove, and the other end of the U-shaped slide seat is slidably installed on the upper surface of the track frame.

[0010] The technical effects and advantages of the present utility model are as follows:

[0011] 1. When it is necessary to adjust the position of the seat plate, rotate the first locking bolt to release the restriction on the convex slide seat, move the seat plate forward or backward to a suitable position, and then reverse the first locking bolt to lock the convex slide seat, thereby locking the seat plate. It can be used by people of different heights and has strong functionality and practicality.

[0012] 2. After the seat plate is adjusted, the second locking bolt can be rotated to move the mounting frame forward or backward so that the backrest is in a suitable position. Then reverse the second locking bolt to lock the U-shaped slide seat, thereby fixing the backrest. Since the lower surface of the square plate abuts against the upper surface of the cross plate, the shaft rod is restricted, so that the shaft rod will not rotate, thereby limiting the mounting frame and the backrest. When the electric vehicle driver is driving the electric vehicle, he can lean on the backrest, improving the comfort of the electric vehicle.

[0013] 3. When the driver needs to temporarily carry items and the length of the seat plate cannot bear them, rotate the second locking bolt to release the restriction on the mounting frame, pull the mounting frame to the end position. At this time, the square plate is separated from the cross plate, and the cross plate no longer restricts the shaft rod. Therefore, the mounting frame can be rotated to a horizontal position, and then the mounting frame is moved forward so that the side surface of the square plate abuts against the upper surface of the cross plate to restrict the mounting frame. The seat is in the second use mode. At this time, the mounting frame lengthens the effective length of the seat plate. Therefore, the carried items can be placed on the seat plate and the backrest, which is convenient for carrying items and increases the practicality of the electric vehicle.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides a Figures 1 - 4 front and rear adjustable seat structure for an electric vehicle as shown. The structure includes a track frame 2 installed on the vehicle frame 1. One end of the track frame 2 is hinged to the vehicle frame 1, and the other end of the track frame 2 is connected to the vehicle frame 1 through a mechanical lock. The connection manner between the track frame 2 and the vehicle frame 1 adopts the connection manner between the seat and the vehicle frame in the prior art, which is convenient for opening the seat to place and take items. This kind of setting belongs to a conventional setting, so it will not be elaborated here.

[0021] In order to solve the problems that choosing multiple electric vehicles will increase the family's capital investment and also occupy more parking space, while choosing one, others will not be very comfortable to use, reducing the functionality and practicality of the electric vehicle. The present utility model slidably installs four convex sliding seats 3 on the track frame 2, and the same seat board 4 is fixedly installed on the four convex sliding seats 3. A first locking bolt 5 is threadedly connected to one of the convex sliding seats 3, and the first locking bolt 5 is cooperatively arranged with the track frame 2. When using the electric vehicle, if it is necessary to adjust the position of the seat board 4, rotate the first locking bolt 5 to release the restriction on the convex sliding seat 3, move the seat board 4 forward or backward to a suitable position, and then reverse the first locking bolt 5 to lock the convex sliding seat 3, thereby locking the seat board 4, which can be suitable for people of different heights to use and has strong functionality and practicality;

[0022] There are two U-shaped sliding seats 6 slidably mounted on the track frame 2. A shaft rod 7 is rotatably mounted on the U-shaped sliding seat 6. The same mounting frame 8 is fixedly mounted on the two shaft rods 7. A backrest 9 is arranged on the mounting frame 8. A second locking bolt 10 is threadedly connected to one of the U-shaped sliding seats 6, and the second locking bolt 10 penetrates through the U-shaped sliding seat 6. The second locking bolt 10 is arranged in cooperation with the track frame 2. After the seat board 4 is adjusted, the second locking bolt 10 can be rotated to move the mounting frame 8 forward or backward so that the backrest 9 is in a proper position. Then, the second locking bolt 10 is reversed to lock the U-shaped sliding seat 6, thereby fixing the backrest 9. At this time, the seat is in the first use mode as Figure 1 shown. Since the lower surface of the square plate 12 abuts against the upper surface of the cross plate 11, the shaft rod 7 is restricted, so that the shaft rod 7 will not rotate. Furthermore, the mounting frame 8 and the backrest 9 are limited, enabling the backrest 9 to support the driver. When the electric vehicle driver is driving the electric vehicle, he can lean on the backrest 9, improving the comfort of the electric vehicle.

[0023] Furthermore, on both sides of the track frame 2 at the top of the vehicle frame 1 of the present utility model, cross plates 11 are fixedly mounted. Square plates 12 are fixedly mounted on both of the two shaft rods 7. The lower surface of the square plate 12 is in movable contact with the upper surface of the cross plate 11. When the driver needs to temporarily carry items and the length of the seat board 4 cannot bear them, the second locking bolt 10 is rotated to release the restriction on the mounting frame 8, and the mounting frame 8 is pulled to the end position. At this time, the square plate 12 is separated from the cross plate 11, and the cross plate 11 no longer restricts the shaft rod 7. Therefore, the mounting frame 8 can be rotated to the horizontal position, and then the mounting frame 8 is moved forward so that the side surface of the square plate 12 abuts against the upper surface of the cross plate 11 to restrict the mounting frame 8. The seat is in the second use mode as Figure 2 shown. At this time, the mounting frame 8 lengthens the effective length of the seat board 4. Therefore, the carried items can be placed on the seat board 4 and the backrest 9, facilitating the carrying of items and increasing the practicality of the electric vehicle.

[0024] Square grooves are formed on both sides of the track frame 2. The first locking bolt 5 penetrates through one of the square grooves and is threadedly connected to the convex sliding seat 3. Moreover, the diameter of the tail end of the first locking bolt 5 is larger than the height of the square groove. When locking the convex sliding seat 3, the front end of the first locking bolt 5 enters the convex sliding seat 3, and the tail end of the first locking bolt 5 abuts against the side surface of the track frame 2. In this way, the convex sliding seat 3 can be locked. This kind of setting belongs to a conventional setting, so no further description will be given.

[0025] One end of the U-shaped sliding seat 6 is slidably mounted inside the corresponding square groove, and the other end of the U-shaped sliding seat 6 is slidably mounted on the upper surface of the track frame 2. Since the square groove is formed on the track frame 2, a straight rail is formed at the upper end of the track frame 2. The U-shaped sliding seat 6 can be stably engaged on the straight rail and can move stably. This kind of setting belongs to a conventional setting, so no further description will be given.
