Description

Technical Field

[0001] This application relates to the field of electric bicycle technology, and in particular to a sensor-activated seat. Background Technology

[0002] An electric bicycle is a vehicle that uses a battery as auxiliary power and is based on a regular bicycle, with the addition of a motor, controller, battery, throttle, brake levers, and other control components, as well as a display system. It has a pedal-assist function, a maximum design speed of no more than 25 km / h, a weight of less than or equal to 55 kg, and an output power of no more than 400 W.

[0003] Most electric bicycles on the market can be powered on and driven by inserting the key into the keyhole. However, the driver needs to hold the handlebars while sitting in front of the seat. If the driver accidentally turns the ignition switch on the right side of the handlebars, the electric bicycle will start and cause an accident, especially for older people. Summary of the Invention

[0004] To improve the safety of electric bicycles, this application provides a sensor-activated seat.

[0005] The sensor-activated seat provided in this application adopts the following technical solution:

[0006] A sensor-operated seat includes a base shell and a foam seat cushion. The foam seat cushion is mounted on the base shell. A sensing component is disposed on the base shell. The sensing component includes a spring, a mounting base, and a micro switch. The mounting base is disposed on the base shell. A limiting component is disposed on the base shell to restrict the mounting base. The micro switch is mounted on the mounting base. The spring is detachably connected to the mounting base. In normal operation, the spring is arched and located below the foam seat cushion. A gap is left between the end of the spring and the contact of the micro switch.

[0007] By adopting the above technical solution, when the driver sits on the foam seat, the foam deforms, pressing the spring. The spring deforms, and its two ends move, contacting the contacts of the microswitches, energizing both microswitches. At this time, the electric bicycle's ignition is activated, and the electric bicycle can be driven. By incorporating a sensing component, under normal conditions, the spring does not contact the microswitch contacts. Only when the driver sits on the foam seat can the spring deform, and the ends of the spring push the microswitch contacts, allowing the electric bicycle to be driven. At other times, the ignition is off. Compared to existing technologies, this reduces the possibility of electric bicycle accidents and improves the safety of electric bicycles.

[0008] Optionally, the bottom shell is provided with a mounting groove, and several limiting grooves are opened on the side wall of the bottom shell away from the sponge cushion at positions corresponding to both sides of the mounting groove. An extension block is connected to the mounting base at the position corresponding to the limiting groove. The mounting base covers the mounting groove, the extension block is adapted to the limiting groove, and the spring piece is located between the sponge cushion and the mounting base.

[0009] By adopting the above technical solution, since the sponge cushion needs to be processed in conjunction with the base shell, the sponge cushion is first installed on the base shell. This means that workers can only operate from the other side of the base shell. An installation groove is provided on the base shell, and the extension block mates with the limiting groove to define the installation position of the mounting base. This allows the spring clip to extend under the sponge cushion, ensuring that the spring clip deforms along with the sponge cushion.

[0010] Optionally, the limiting component includes a limiting bolt that passes through the extension block and the base shell and is threaded into the base shell.

[0011] By adopting the above technical solution, when restricting the mounting base, the screwdriver is used to rotate the restricting bolt to make the extension block press against the restricting groove, which is simple and convenient to operate and improves the installation convenience of the base.

[0012] Optionally, the limiting component includes a pressure plate, a rotating rod, and a limiting claw. The pressure plate is an L-shaped plate, with one end rotatably connected to the bottom shell. One end of the rotating rod is rotatably connected to the bottom shell. A fixing block is connected to the bottom shell, and the limiting claw is vertically connected to the fixing block. When the mounting base is limited, the pressure plate presses down on the extension block, the rotating rod is in contact with the pressure plate, and the other end of the rotating rod is engaged between the fixing block and the limiting claw.

[0013] By adopting the above technical solution, when the mounting base is restricted, the pressure plate is flipped over and the pressure plate is attached to the extension block. Then, the rotating rod is moved and pressed, and the rotating rod abuts against the restricting claw, restricting the deformation of the claw, until the rotating rod abuts against the fixing block. At this time, the end of the rotating rod is restricted between the restricting claw and the fixing block, and the rotating rod is attached to the side wall of the pressure plate, thereby restricting the rotation of the pressure plate, restricting the degree of freedom of the mounting base, and realizing the installation of the mounting base.

[0014] Optionally, both ends of the spring are connected to extension pieces, and the ends of the extension pieces are connected to abutment pieces. A gap is left between the abutment pieces and the contacts of the micro switch. Mounting notches are provided on both sides of the extension pieces. A stop block is connected to the mounting base at the position corresponding to the mounting notch, and the stop block is partially located within the mounting notch.

[0015] By adopting the above technical solution, when installing the spring clip, the extension piece is fitted onto the stop block, so that the stop block is located within the installation notch. The spring clip then returns to its original position, causing the side wall of the installation notch to press against the stop block, thereby restricting the degree of freedom of the spring clip and realizing the installation of the spring clip.

[0016] Optionally, the mounting base is provided with a protective cover, the mounting base is provided with a positioning element that restricts the installation position of the protective cover, the protective cover covers the micro switch, the mounting base is provided with a locking element that restricts the movement of the protective cover, and the abutment is located inside the protective cover.

[0017] By adopting the above technical solution, the protective cover is defined by a positioning component and its movement is restricted by a locking component. The protective cover serves two purposes: firstly, it shields the microswitch, reducing the possibility of damage; secondly, by restricting the contact piece, it further restricts the spring contact, improving the installation stability of the spring contact.

[0018] Optionally, the locking element is a locking claw, and several locking elements are connected on the protective cover. The bottom shell has a snap-fit ​​groove at the position corresponding to the locking element, and the locking element engages with the snap-fit ​​groove.

[0019] By adopting the above technical solution, when installing the protective cover, the positioning component is used to limit the installation position and angle of the protective cover. Then, the locking component passes through the snap-fit ​​groove and engages with the snap-fit ​​groove, thereby limiting the degree of freedom of the protective cover and realizing the installation of the protective cover.

[0020] Optionally, the mounting base is provided with a cable tray, and several limiting blocks are connected to both sides of the cable tray on the mounting base. The connecting wire of the micro switch passes through the cable tray and is located between the limiting blocks and the bottom wall of the cable tray.

[0021] By adopting the above technical solution, the arrangement of the micro switch's connecting wires affects the compactness and reliability of the entire sensing component. By setting up a cable tray and a limiting block, the micro switch's connecting wires are confined between the limiting block and the bottom wall of the cable tray, reducing the possibility of movement and damage to the micro switch's connecting wires.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the driver sits on the foam seat, the foam deforms, pressing down on the spring. The spring deforms, and its two ends move, contacting the contacts of the microswitches, energizing both microswitches. At this point, the electric bicycle's ignition is activated, allowing the driver to ride. By incorporating a sensing component, the spring is not normally in contact with the microswitch contacts. Only when the driver sits on the foam seat does the spring deform, and its ends push the microswitch contacts, allowing the driver to ride. At other times, the ignition is off. Compared to existing technologies, this reduces the likelihood of electric bicycle accidents and improves the safety of electric bicycles.

[0024] 2. When restricting the mounting base, flip the pressure plate so that it fits against the extension block. Then, move and press the rotating rod so that it contacts the limiting claw, causing the claw to deform until it contacts the fixing block. At this point, the end of the rotating rod is restricted between the limiting claw and the fixing block, and the rotating rod fits against the side wall of the pressure plate, thereby restricting the rotation of the pressure plate and limiting the degree of freedom of the mounting base, thus realizing the installation of the mounting base.

[0033] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0034] Embodiment 1 of this application discloses a sensor-activated seat. (Refer to...) Figure 1 and Figure 2 The sensor seat includes a base shell 1 and a sponge cushion 2, which is mounted on the base shell 1. The base shell 1 has an installation groove, and several limiting grooves 11 are provided on the side wall of the base shell 1 away from the installation groove at positions opposite to the sides. This embodiment uses three such grooves.

[0035] Reference Figure 2 , Figure 3 and Figure 4 A sensing component 3 is provided on the bottom shell 1. The sensing component 3 includes a spring 31, a mounting base 32, and a micro switch 33. An extension block 321 is fixedly connected to the mounting base 32 at a position corresponding to the limiting groove 11. The extension block 321 is adapted to fit into the limiting groove 11, and the mounting base 32 covers the mounting groove. A limiting component 4 is provided on the mounting base 32. The limiting component 4 includes a limiting bolt 41. The limiting bolt 41 passes through the extension block 321 and the bottom shell 1 and is threadedly engaged with the bottom shell 1.

[0036] Reference Figure 4 Both ends of the spring piece 31 are integrally formed with extension pieces 311, and the sides of the extension pieces 311 are integrally formed with abutment pieces 312, which are perpendicular to the extension pieces 311. Mounting notches 3111 are formed on both opposite sides of the extension pieces 311. A stop block 324 is fixedly connected to the mounting base 32 at a position corresponding to the mounting notch 3111, with part of the stop block 324 located within the mounting notch 3111. The spring piece 31 is located between the mounting base 32 and the sponge cushion 2.

[0037] Reference Figure 4 and Figure 5One microswitch 33 is installed on the mounting base 32 at each end corresponding to the two ends of the spring contact 31. The two microswitches 33 are arranged opposite each other, and a gap is left between the contact piece 312 and the contact of the microswitch 33. The mounting base 32 is provided with a cable tray 322, and several limiting blocks 323 are provided on both sides of the cable tray 322. The connecting wire of the micro switch 33 is arranged between the limiting blocks 323 and the bottom wall of the cable tray 322.

[0038] Reference Figure 2 and Figure 4 The mounting base 32 is provided with a protective cover 5, which covers the micro switch 33 and the contact piece 312. A positioning element 325 is provided on the stop block 324. In this embodiment, the positioning element 325 is a positioning post, which is fixedly connected to the stop block 324 and inserted into the protective cover 5. A locking element 51 is provided on the protective cover 5. The locking element 51 is a locking claw, and several locking elements 51 are fixedly connected to the protective cover 5. In this embodiment, four are used as an example. A snap-fit ​​groove is opened on the mounting base 32 at the position corresponding to the locking element 51. The locking element 51 passes through the snap-fit ​​groove and engages with it.

[0039] The implementation principle of the sensor seat in Embodiment 1 of this application is as follows: When the driver sits on the sponge cushion 2, the sponge cushion 2 deforms and applies pressure to the spring 31. The spring 31 deforms, causing the contact piece 312 to move. The contact piece 312 pushes the contact of the micro switch 33, at which time the electric bicycle is powered on and started, and the electric bicycle can be driven.

[0040] By setting the sensing component 3, under normal conditions, the spring 31 does not contact the contacts of the micro switch 33. Only when the driver sits on the sponge seat 2 can the spring 31 deform, and the end of the spring 31 pushes the contacts of the two micro switches 33. Only then can the electric bicycle be driven through the ignition switch. At other times, the ignition switch is in the off state. Compared with the existing technology, this reduces the possibility of electric bicycle accidents and improves the safety of electric bicycles.

[0041] Example 2: The difference between this example and Example 1 is that the structure of the limiting component 4 is different.

[0042] Reference Figure 6 and Figure 7 The limiting component 4 includes a pressure plate 42, a rotating rod 43, and a limiting claw 44. The pressure plate 42 is an L-shaped plate, and one of the pressure plates 42 is hinged to the bottom shell 1 at the position corresponding to the extension block 321. One end of the rotating rod 43 is hinged to the bottom shell 1. A fixing block 441 is fixedly connected to the bottom shell 1, and the limiting claw 44 is fixedly connected to the fixing block 441. During installation, the pressure plate 42 is in contact with the extension block 321, and the end of the rotating rod 43 is limited between the fixing block 441 and the limiting claw 44, with the rotating rod 43 in contact with the pressure plate 42.

[0043] When installing the mounting base 32, the extension block 321 is fitted into the limiting groove 11, the pressure plate 42 is flipped, and the end of the rotating rod 43 is moved and pressed. The rotating rod 43 abuts against the limiting claw 44, and the limiting claw 44 deforms until the rotating rod 43 abuts against the fixing block 441. The limiting claw 44 returns to its original position and restricts the rotation of the rotating rod 43. At this time, the rotating rod 43 is in contact with the pressure plate 42, thus realizing the installation of the mounting base 32.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
