Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a seat opening device for an electric vehicle wake-up system that uses tapping on the vehicle body. Background Technology

[0002] Electric vehicles, also known as electric cars, are pure electric motor vehicles powered by batteries and driven by electric motors (DC, AC, series, and separately excited). They can be classified according to the number of wheels into two-wheeled electric vehicles, three-wheeled electric vehicles, and electric cars, thus meeting different environments and usage needs.

[0003] Currently, in existing two-wheeled electric vehicle technology, to meet people's needs for storing items, the seat and body structures are designed to be reversible, with storage space created within the area covered by the seat. This allows for storage without interfering with riding, offering great flexibility. However, to ensure structural stability, a locking mechanism is installed between the seat and body to prevent accidental opening. This also means users must carry a key when opening the storage space without riding the vehicle, which is inconvenient. Furthermore, if the key is lost and the storage space needs to be opened urgently, the body or seat structure must be damaged by force, resulting in significant losses and increased repair costs. Therefore, it is clear that existing two-wheeled electric vehicles still require further improvement in terms of seat opening mechanisms. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a seat opening device for an electric vehicle's vehicle body tapping wake-up system, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a seat opening device for an electric vehicle body wake-up system by tapping the vehicle body, including an electric vehicle body and a seat body installed on the top of one side of the electric vehicle body. The interior of one side of the electric vehicle body has a storage space covered by the seat body. The bottom structure of one side of the seat body and the inner wall of the storage space are hinged by a pin and a torsion spring. A semi-open box is installed on the front inner wall of one side of the storage space. A hollow pressure plate is snapped into the front structure of the semi-open box. The front structure of the hollow pressure plate penetrates the front structure of the electric vehicle body and extends to the outer side of the front of the electric vehicle body.

[0006] The semi-open box is fitted with an arc-shaped toothed plate that can rotate synchronously with the seat body. Inside the semi-open box are a pressure sensor, an elastic reset rod, a compound gear component, an electromagnetic limit component, a controller, and a normally open switch. The elastic reset rod is installed between the hollow pressure plate and the pressure sensor and can move and adjust synchronously with the hollow pressure plate to apply pressure to the pressure sensor. The pressure sensor is electrically connected to the controller via a wire.

[0007] The electromagnetic limiting component can magnetically connect the composite gear component and electrically connect it to the controller via a wire. One end of the arc-shaped toothed plate meshes with the composite gear component for transmission, and the normally open switch is located below one end of the arc-shaped toothed plate and electrically connected to the controller via a wire.

[0008] Specifically, the elastic reset rod includes a guide sleeve, a T-shaped pressure rod, and a reset spring. The middle part of the T-shaped pressure rod is engaged with the inner top of the guide sleeve, and the bottom of the guide sleeve is fixedly connected to the inner wall of the bottom of the semi-open box. The front end structure of the T-shaped pressure rod is connected to the inner rear end of the hollow pressure plate, and there is clearance space between the rear end structure of the T-shaped pressure rod and the pressure sensor. The two ends of the reset spring are respectively fixedly connected to the inner wall of the rear end of the semi-open box and the inner wall of the rear end of the hollow pressure plate.

[0009] The selected method involves setting four reset springs to ensure the reliability of the hollow pressure plate's reset movement. Each of the four reset springs has a constraint rod inside it. One end of each constraint rod is fixedly connected to the inner wall of the four corners at the rear end of the semi-open box. The constraint rods guide the reciprocating deformation of the reset springs and reduce the deformation amplitude of the reset springs other than that caused by external pressure through friction, thereby reducing the probability of false pressure on the pressure sensor.

[0010] Selectedly, the composite gear component includes a gear shaft, both ends of which are optical shaft structures, and one end of the gear shaft is fitted with a bearing seat mounted on the inner wall of one side of the semi-open box via a bearing. The other end of the gear shaft is fixedly connected to an iron disc, and the middle part of the gear shaft is meshed with one end of an arc-shaped gear plate.

[0011] The electromagnetic limiting component consists of a support sleeve and an electromagnetic chuck fitted inside one side of the support sleeve. The other side of the support sleeve is fixedly connected to the inner wall of one side of the semi-open box. The electromagnetic chuck is magnetically connected to the rear end face of the iron disc, thereby meeting the assembly limiting requirements between the seat body and the electric vehicle body.

[0012] Preferably, a T-shaped flange head is fixedly connected to the other end of the arc-shaped toothed plate. The T-shaped flange head is installed with screws at the corresponding position of the inner wall of the seat body, which improves the flexibility of assembly. The rotation center of the arc-shaped toothed plate is the same as the rotation center of the seat body.

[0013] The semi-open box has a recessed groove and a threaded hole in its rear structure. The threaded hole communicates with the recessed groove. A sealing cover is fitted into the recessed groove, and the sealing cover has a countersunk hole that aligns with the threaded hole. The semi-open box and the sealing cover are installed by screws passing through the countersunk hole and threaded into the threaded hole. A protective filter is nested inside the sealing cover. The detachable installation design between the sealing cover and the semi-open box provides convenient conditions for subsequent maintenance of the internal components of the semi-open box.

[0014] Selectedly, the front surface of the electric vehicle body is nested with an elastic waterproof gasket. The elastic waterproof gasket can fully cover the hollow pressure plate and the semi-open box. The elastic waterproof gasket can deform itself to meet the reciprocating movement requirements of the hollow pressure plate inside the semi-open box, while providing waterproof protection at the connection between the hollow pressure plate and the electric vehicle body, ensuring that the whole device operates normally in rainy weather.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model comprises a multi-functional limiting mechanism consisting of a pressure sensor, an arc-shaped toothed plate, a composite gear component, an electromagnetic limiting component, a controller, and a normally open switch. When used in conjunction with a hollow pressure plate and an elastic reset rod, it can, without interfering with the seat's free rotation on the electric vehicle, press the hollow pressure plate and elastic reset rod to cause the pressure sensor to output pressure data. Once the specified pressure data is reached, the electromagnetic limiting component closes, releasing the limit. This allows the seat to rotate freely on the electric vehicle while facilitating the loading and unloading of items. After subsequent rotation and resetting of the seat, the arc-shaped toothed plate presses the normally open switch again, opening the electromagnetic limiting component and restoring the limiting lock between the arc-shaped toothed plate and the composite gear component, and between the electric vehicle and the seat. This effectively solves the problems existing in the prior art.

[0017] 2. During the riding and moving process of the entire device, the hollow pressure plate of this utility model will move slightly inside the semi-open box under the action of four return springs due to the vibration of the movement. In conjunction with the filter channel inside the sealing cover, it can achieve the effect of reciprocating suction of the air inside the semi-open box, accelerate the air flow between the air inside the semi-open box and the storage space, assist in the heat dissipation of the electronic components inside the semi-open box, and further optimize the overall use effect of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7A seat opening device for an electric vehicle body-tapping wake-up system includes an electric vehicle body 1 and a seat body 2 installed on the top of one side of the electric vehicle body 1. The interior of one side of the electric vehicle body 1 has a storage space covered by the seat body 2. The bottom structure of one side of the seat body 2 is hinged to the inner wall of the storage space by a pin and a torsion spring. A semi-open box 4 is installed on the front inner wall of the storage space. A hollow pressure plate 5 is snapped into the front structure of the semi-open box 4. The front structure of the hollow pressure plate 5 penetrates the front structure of the electric vehicle body 1 and extends to the outer side of the front of the electric vehicle body 1.

[0028] The semi-open box 4 has a relief groove and a threaded hole in its rear structure. The threaded hole and the relief groove are connected. A sealing cover 3 is snapped into the relief groove. The sealing cover 3 has a countersunk hole that can be aligned with the threaded hole. The semi-open box 4 and the sealing cover 3 are installed by screws passing through the countersunk hole and being threaded into the threaded hole. A protective filter is nested inside the sealing cover 3. The detachable installation design between the sealing cover 3 and the semi-open box 4 can provide convenient conditions for the subsequent maintenance of the internal components of the semi-open box 4.

[0029] The semi-open box 4 has an arc-shaped toothed plate 6 that can rotate synchronously with the seat body 2 on the inner side of its middle section. The other end of the arc-shaped toothed plate 6 is fixedly connected to a T-shaped flange head 16. The T-shaped flange head 16 is installed with the inner wall of the corresponding position of the seat body 2 by screws, which improves the flexibility of assembly. The rotation center of the arc-shaped toothed plate 6 is the same as the rotation center of the seat body 2. The interior of the semi-open box 4 contains a pressure sensor 7, an elastic reset rod, a compound gear component 12, an electromagnetic limit component 13, a controller 14, and a normally open switch 15. The elastic reset rod is installed between the hollow pressure plate 5 and the pressure sensor 7 and can move and adjust synchronously with the hollow pressure plate 5 to apply pressure to the pressure sensor 7. The pressure sensor 7 is electrically connected to the controller 14 through a wire.

[0030] The elastic reset rod includes a guide sleeve 8, a T-shaped pressure rod 9, and a reset spring 10. The middle part of the T-shaped pressure rod 9 is engaged with the inner top of the guide sleeve 8, and the bottom of the guide sleeve 8 is fixedly connected to the inner wall of the bottom of the semi-open box 4. The front end of the T-shaped pressure rod 9 is connected to the inner rear end of the hollow pressure plate 5, and there is clearance space between the rear end of the T-shaped pressure rod 9 and the pressure sensor 7. The two ends of the reset spring 10 are respectively fixedly connected to the inner wall of the rear end of the semi-open box 4 and the inner wall of the rear end of the hollow pressure plate 5. There are four reset springs 10 to ensure the reliability of the reset movement of the hollow pressure plate 5. Each of the four reset springs 10 has a constraint rod 11 engaged inside. One end of the four constraint rods 11 is respectively fixedly connected to the inner wall of the four corners of the rear end of the semi-open box 4. The constraint rods 11 guide the reciprocating deformation of the reset spring 10 and reduce the deformation amplitude of the reset spring 10 except for the external pressure by friction, thereby reducing the probability of false pressure on the pressure sensor 7.

[0031] The electromagnetic limit component 13 can magnetically connect the composite gear component 12 and electrically connect it to the controller 14 through a wire. One end of the arc-shaped toothed plate 6 meshes with the composite gear component 12 for transmission, and the normally open switch 15 is located below one end of the arc-shaped toothed plate 6 and electrically connected to the controller 14 through a wire.

[0032] The composite gear component 12 includes a gear shaft 121, both ends of which are optical shaft structures. One end of the gear shaft 121 is fitted with a bearing seat mounted on the inner wall of one side of the semi-open box 4. The other end of the gear shaft 121 is fixedly connected to an iron disc 122. The middle part of the gear shaft 121 is meshed with one end of the arc-shaped toothed plate 6. The electromagnetic limiting component 13 consists of a support sleeve and an electromagnetic chuck fitted inside one side of the support sleeve. The other side of the support sleeve is fixedly connected to the inner wall of one side of the semi-open box 4. The electromagnetic chuck is magnetically connected to the rear end face of the iron disc 122, thereby satisfying the assembly limiting requirements between the seat body 2 and the electric vehicle body 1.

[0033] An elastic waterproof gasket 17 is nested on the front surface of the electric vehicle body 1. The elastic waterproof gasket 17 can fully cover the hollow pressure plate 5 and the semi-open box 4. The elastic waterproof gasket 17 can deform itself to meet the reciprocating movement requirements of the hollow pressure plate 5 inside the semi-open box 4, while providing waterproof protection for the connection between the hollow pressure plate 5 and the electric vehicle body 1, ensuring that the whole device can operate normally in rainy weather.

[0034] Working principle: Example 1

[0035] When the seat body 2 needs to be opened, the operator can press the elastic waterproof pad 17, which will then press the hollow pressure plate 5 and drive the T-shaped pressure rod 9 to move into the semi-open box 4 to press the pressure sensor 7. Then the pressure sensor 7 outputs pressure data value to the controller 14. When the pressure data value reaches the specified data value, the controller 14 closes the electromagnetic chuck in the electromagnetic limit component 13, which was originally in the open state, and then releases the electromagnetic chuck from the magnetic attraction limit of the composite gear component 12.

[0036] After the electromagnetic chuck is closed, the seat body 2 will automatically flip and separate from the electric vehicle body 1 under the support of the corresponding torsion spring and pin. At the same time, the arc-shaped toothed plate 6 will also rotate synchronously with the seat body 2, temporarily relieving the pressure on the normally open switch 15. The normally open switch 15 returns to the normally open state, further disconnecting the controller 14 from the control of the electromagnetic chuck.

[0037] After removing the items from the storage space of the electric vehicle body 1, flip and press the seat body 2 to reset it. Under the support of the corresponding torsion spring and pin, the seat body 2 drives the arc-shaped toothed plate 6 to move down and reset. The arc-shaped toothed plate 6 will re-engage with the compound gear component 12 and, after the seat body 2 and the electric vehicle body 1 are completely reset, apply pressure to the normally open switch 15 to restore the controller 14's control over the electromagnetic chuck and activate the electromagnetic chuck. The electromagnetic chuck then re-magnetically attracts and limits the compound gear component 12, ensuring the stability of the electric vehicle body 1 and the seat body 2 after assembly. Example 2

[0038] During the riding and movement of the entire device, the hollow pressure plate 5 will also move slightly inside the semi-open box 4 under the action of the four return springs 10 due to the vibration of the movement. Then, in conjunction with the filter channel inside the sealing cover 3, the air inside the semi-open box 4 can be reciprocated and sucked up, thereby accelerating the air flow between the air inside the semi-open box 4 and the storage space, assisting in the heat dissipation of the various electronic components inside the semi-open box 4, and optimizing the use effect.
