Thus, the user rotates the handle structure 3 to rotate the front fork 13, so that the front wheel 21 rotates around the axis of the rotating shaft, thereby changing the driving direction of the electric bicycle 100. Specifically, the handlebar structure 3 may include a stem, and left and

right handlebars

31 and 32 symmetrically disposed at a top end of the stem along an axis of the stem, a bottom end of the stem being connected to the rotation shaft. Wherein, left handlebar 31 can buckle body and first horizontal body including consecutive first body of buckling, second, and first body of buckling deviates from the second one end of buckling the body and is connected with the handlebar axle, and first horizontal body is used for supplying the user to hold. The first bending pipe body, the second bending pipe body and the first horizontal pipe body can be integrally formed through injection molding, forging and the like, so that the left handlebar 31 is formed into a whole, and the installation process is omitted. In addition, the structure of the right handle bar 32 is similar to that of the left handle bar 31, and the description thereof is omitted.

In order to intelligently control the electric bicycle 100, the electric bicycle 100 further includes a central control device 4, the central control device 4 is disposed between the left handle bar 31 and the right handle bar 32, and the central control device 4 is used for controlling the electric bicycle 100. Thus, the electric bicycle 100 is controlled by the central control device 4, and the degree of intelligence is high. Moreover, the use of the space between the left and

right handlebars

Fig. 2 is a schematic overall structure diagram of a central control device in an embodiment of the present disclosure, fig. 3 is a cross-sectional view of the central control device in the embodiment of the present disclosure, and fig. 4 is an exploded schematic diagram of the central control device in the embodiment of the present disclosure. As shown in fig. 2 to 4, the center control apparatus 4 includes an upper case 41, a lower case 42, a key 48, and an integrated circuit board 44 disposed in a mounting space surrounded by the upper case 41 and the lower case 42. Wherein, the integrated circuit board 44 is integrated with a processor and a tact switch 49 electrically connected with the processor; the upper case 41 is formed with a mounting hole, the key 48 is accommodated in the mounting hole and sealed with the hole wall of the mounting hole, and the key 48 is configured to control the on/off of the tact switch 49; an elastic piece is arranged between the key 48 and the tact switch 49 and used for providing elastic force for the key 48 far away from the tact switch 49; the processor is configured to execute a built-in preset program in response to the on/off signal of the tact switch 49.

Therefore, when the user uses the electric bicycle 100, the user only needs to press the key 48, the key 48 controls the light touch switch 49 to be turned on, the circuit of the integrated circuit board 44 is conducted, and the processor responds to the turn-on signal of the light touch switch 49 to start a bicycle returning program, so that the one-key bicycle returning function is realized. When the external force is removed from the key 48, the key 48 is reset under the elastic force of the elastic member, the tact switch 49 is turned off, and the circuit is disconnected.

Optionally, the lower casing 42 is a first box with an opening on the top wall, the upper casing 41 is a second box with an opening on the bottom wall, the first box is in butt joint with the second box, and an internal cavity of the first box and an internal cavity of the second box form an installation space together; alternatively, the lower case 42 has a box structure with an open top wall, and the upper case 41 has a cover structure covering the open top wall of the lower case 42. The box body and the box body can be in regular shapes such as a cylinder shape, a cuboid shape and the like, and can also be in other irregular shapes. For example, in the example shown in fig. 4, the lower case 42 is a box structure whose top wall is open, and the outer shape of the box is composed of a rectangular portion and a semicircular portion.

Illustratively, the lower case 42 is detachably connected to the upper case 41, thereby facilitating maintenance of the integrated circuit board 44 and the like mounted in the mounting space. Specifically, the upper casing 41 and the lower casing 42 are connected through the fastening bolt, a connecting flange is formed at the top of the lower casing 42, a first through hole is formed in the connecting flange, the mounting seat 411 is formed on the upper casing 41, a second through hole is formed in the bottom surface of the mounting seat 411, when the upper casing 41 and the lower casing 42 are in butt joint, the center line of the first through hole and the center line of the second through hole are collinear, and the fastening bolt sequentially penetrates through the first through hole and the second through hole and then is connected with the nut.

The shape of the integrated circuit board 44 is not limited as long as it is accommodated in the installation space. In the embodiment shown in fig. 4, the integrated circuit board 44 is composed of a rectangular portion and a trapezoidal portion, and the bottom side of the trapezoid is connected to the rectangle, whereby the present embodiment provides that the integrated circuit board 44 is fitted to the lower case 42 which is composed of a box structure composed of a rectangular portion and a semicircular portion. Further, the integrated circuit board 44 is detachably connected to the top of the lower case 42 in a box structure, so that the integrated circuit board 44 can be detached for maintenance and replacement. Illustratively, the integrated circuit board 44 and the lower shell 42 may be connected by screws, the integrated circuit board 44 is provided with a connecting through hole, the top of the lower shell 42 is provided with a threaded hole, and the screws penetrate through the connecting through hole to be matched with the threaded hole.

Integrated circuit board 44 has a processor integrated thereon, and this processor can be an MCU chip (Microcontroller Unit), a PLC (Programmable Logic Controller), an ICU (Inner Control Unit) or a single chip microcomputer, and the present invention is not limited thereto. The processor is electrically connected to the tact switch 49, the tact switch 49 sends an on/off signal to the processor according to the on condition of the tact switch, and the processor receives the on/off signal to execute a built-in preset program, that is, a one-touch returning mode (refer to the following description).

Alternatively, the elastic member may be a glue column aligned with the tact switch 49 on the integrated circuit board 44; or, the elastic member may be an abutting spring, the bottom of the key 48 is further connected with a return spring, and one end of the return spring, which is away from the key 48, is connected with the top wall of the mounting hole on the upper housing 41. Therefore, after the external force is removed from the key 48, the rubber column returns under the action of the dual elastic forces of the abutting spring and the return spring, so that the key 48 and the tact switch 49 can be quickly disconnected, and the processor can quickly respond to the on/off signal of the tact switch 49.

Fig. 5 is a partially enlarged view of a portion a in fig. 3. Preferably, the elastic member is a spring plate 410, an outer edge of the spring plate 410 is fixedly connected with the upper housing 41, a top wall of the spring plate 410 is connected with the key 48, and a bottom wall of the spring plate 410 is provided with a protrusion 4101 for pressing the tact switch 49 to control the tact switch 49 to open/close. Thus, the spring plate 410 has a larger area than the spring, and thus is more reliably connected to the key 48. The elastic sheet 410 may be a rubber elastic sheet, a silicone elastic sheet, or an elastic plastic elastic sheet 410, which is not limited in this embodiment. The protrusion 4101 disposed on the bottom wall of the elastic sheet 410 may be circular, and at this time, the mounting hole is also circular, so that the mounting hole is matched with the protrusion 4101.

In the example shown in fig. 3 and 5, an installation groove 412 surrounding the installation hole is provided at an outer side of the installation hole of the upper case 41, and an edge of the resilient piece 410 is received in the installation groove 412 and is closely fitted to the installation groove 412. Thereby, the elastic piece 410 is tightly coupled with the upper case 41.

In an example of the present disclosure, an edge of the resilient tab 410 may be in interference fit with the mounting groove 412, such that the resilient tab 410 is snapped into the mounting groove 412. Thus, the connection mode of the elastic sheet 410 and the mounting groove 412 is simple.

In another example of the present disclosure, the edge of the elastic sheet 410 may be injection molded in the mounting groove 412 by a secondary injection molding process, so that the elastic sheet 410 is not only tightly connected to the upper housing 41, but also the elastic sheet 410 and the upper housing 41 may be integrated by injection molding, which is beneficial to improving the sealing property between the key 48 and the upper housing 41. Because the shared electric bicycle 100 needs to be exposed in the outdoor environment for a long time, the arrangement can prevent rainwater from entering the installation space from the gap between the elastic sheet 410 and the upper shell 41 to affect the working performance of the integrated circuit board 44 and the antenna 45, and a waterproof effect is achieved. It should be noted that the edge of the elastic sheet 410 is clamped in the mounting groove 412, and a certain gap is formed between the bottom of the edge of the elastic sheet 410 and the bottom surface of the mounting groove 412, so as to ensure that the elastic sheet 410 has a certain compression displacement downward when the key 48 is pressed, thereby ensuring that the elastic sheet 410 can work effectively.

The part of the elastic sheet 410, which is positioned outside the mounting hole, is provided with an accommodating groove 4102 surrounding the key 48, the longitudinal section of the accommodating groove 4102 is a right trapezoid, the inclined edge of the right trapezoid is far away from the key 48, and the short edge of the right trapezoid is the groove bottom of the accommodating groove 4102. That is, the inner walls of the accommodation grooves 4102 are inclined from the top to the bottom in the right-downward direction. Therefore, compared with the case where the inner walls of the accommodation grooves 4102 are inclined from the top to the bottom in the lower left direction, dust in the outdoor environment is accumulated in the accommodation grooves 4102, and does not easily enter the installation space from the gap between the elastic piece 410 and the upper housing 41, thereby playing a role of dust prevention. Further, the top of the elastic sheet 410 is farther away from the ground than the outer surface of the upper shell 41, so that the elastic sheet 410 can be shielded above the joint of the elastic sheet 410 and the upper shell 41, and the dustproof effect is further achieved.

With continued reference to fig. 3 and 5, the central control device 4 further includes a light guide pole 10 disposed in the installation space and an indicator light 442 disposed on the integrated circuit board 44, the key 48 and the elastic piece 410 are made of a light-transmitting material, the indicator light 442 is disposed near the light guide pole 10, and light emitted from the indicator light 442 can be emitted out of the central control device 4 through the light guide pole 10, the elastic piece and the key 48. When the tact switch 49 is turned on by pressing the button 48, the indicator 442 connected to the ic board 44 is energized to emit light, and the light guide bar 10 transmits the light to the button 48 and the elastic member, so that the button 48 emits light. Therefore, the user is prompted to press the key 48 successfully by the aid of the light-emitting of the key 48, namely, the user is prompted to return to the vehicle by one key, and the function of prompting the user to observe whether the electric bicycle 100 is returned successfully or not in the next step can be achieved.

The key 48, the spring 410 and the light guide bar 10 may be ABS plastic or PVC plastic (polyvinyl chloride) with good light transmittance. The indicator light 442 may be an LED light, a light emitting diode, or other examples known to those skilled in the art.

It should be noted that the light emitted by the indicator light 442 should be understood in a broad sense, that is, the color of the light emitted by the indicator light 442 may be red, green, orange, etc.; the indicator light 442 is disposed adjacent to the light guide 10, and should be understood broadly, so long as the light emitted from the indicator light 442 can be emitted to the key 48 through the light guide 10. Preferably, the indicator light 442 is disposed under the light guide bar 10 and opposite to the light guide bar 10. Therefore, the phenomenon that the light is weakened due to reflection in the light transmission process is avoided.

Fig. 6 is an exploded schematic view of a partial structure of a central control device in an embodiment of the present disclosure, fig. 7 is a schematic view of an upper housing of the central control device in the embodiment of the present disclosure connected to a light guide pillar, and fig. 8 is a schematic view of a structure of the light guide pillar of the central control device in the embodiment of the present disclosure. In the example shown in fig. 6 to 8, the light guide bar 10 includes a first light guide 101 and a second light guide 102 connected to each other, the first light guide 101 is accommodated in the mounting hole, and the second light guide 102 is located in the mounting space. Thus, by adjusting the shapes of the first and second

light guide bodies

101 and 102, the light guide pole 10 can be adapted to various shapes of the keys 48 and the mounting holes.

For example, the first light guide 101 is a prism, the second light guide 102 is a cylinder, and the cross-sectional area of the second light guide 102 is smaller than or equal to the cross-sectional area of the first light guide 101. Thus, the cross-sectional area of the tip of the light guide bar 10 is larger than the cross-sectional area of the entire light guide bar 10, and more light can be transmitted to the key 48, so that the key 48 is brighter. When the second light guide 102 has a cylindrical shape, the outer wall of the second light guide 102 is further provided with ribs 103, thereby improving the strength of the second light guide 102. In another implementation, the second light guide 102 may be in a circular truncated cone shape, and a cross-sectional area of one end of the second light guide 102 connected to the first light guide 101 is larger than a cross-sectional area of the other end of the second light guide 102.

As is apparent from the above description, the mounting hole may be composed of a rectangular portion through which the protrusion 4101 of the elastic sheet 410 passes and a circular portion through which the first light guide 101 of the light guide bar 10 is received.

The light guide post 10 and the mounting hole may be connected by clamping, screwing or welding. In the example shown in fig. 7, at least one fixing post is disposed at the mounting hole of the bottom wall of the upper housing 41, at least one wall plate 104 is connected to the side wall of the first light guide 101 of the light guide 10, fixing holes are disposed on the wall plate 104, the center line of one fixing hole and the center line of one fixing post are arranged in a collinear manner, and the fixing post is inserted into the fixing hole. Thus, the light guide pole 10 and the upper case 41 are connected by a plug-in manner, and the installation manner is simple. When the number of the fixing posts is two, the number of the wall plates 104 may also be two, and the two wall plates 104 are oppositely disposed on two sides of the first light guide 101.

On the basis of the above embodiment, the central control apparatus 4 further includes the first fool-proof structure 110, and the first fool-proof structure 110 is disposed between the upper housing 41 and the elastic sheet 410 to ensure the correct connection between the upper housing 41 and the elastic sheet 410. That is, the first fool-proof structure 110 is disposed between the upper housing 41 and the elastic piece 410. Therefore, the upper shell 41 and the shrapnel 410 are correctly matched, so that the projection 4101 on the shrapnel 410 can correctly extend into the installation space, and the key 48 can normally work.

For example, the integrated circuit board 44 is provided with a power interface, the power interface is electrically connected to a power supply pin of the processor through a printed circuit on the integrated circuit board 44, and the battery 43 is connected to the power interface through a cable. In addition, the battery 43 can be connected to the battery assembly through a cable, and when the power of the battery 43 is exhausted, the battery assembly charges the battery 43 through the cable to ensure that the central control device 4 can normally operate.

Fig. 11 is a structural schematic view of a lower case of a center control apparatus according to an embodiment of the present disclosure, and fig. 12 is a sectional view of a connection between a battery and the lower case according to an embodiment of the present disclosure. Illustratively, an annular flange 421 is disposed on the inner bottom wall of the lower casing 42, the annular flange 421 and the lower casing 42 enclose an accommodating cavity, and the battery 43 is disposed in the accommodating cavity.

In one implementation, the lower housing 42 further includes a catching arm 422, one end of the catching arm 422 is connected to the annular flange 421, the other end of the catching arm 422 is a free end, and the catching arm 422 and the inner bottom wall of the lower housing 42 together define a catching space for catching the battery 43. Thereby, the battery is engaged with the lower case 42 in a simple manner, and the catching arm 422 restricts the battery 43 from moving toward the upper case 41 to fix the battery 43 in the installation space.

Optionally, the catch arm 422 is configured in an arc shape, and the arc-shaped catch arm 422 wraps around the upper surface of the battery 43, thereby making the catch arm 422 more conformable to the outer wall of the battery 43. In addition, a reinforcing rib 4221 can be further disposed on the side wall of the retaining arm 422 departing from the retaining space, so as to improve the strength of the retaining arm 422.

Therefore, the elastic buckle 423 has good strength and elasticity, further clamps the battery 43, and improves the connection stability of the battery 43 and the lower shell 42. When the battery 43 is detached, the stand arm is pulled away from the battery 43, and then the battery 43 is taken out from the free end of the catch arm 422.

Of course, the present invention is not limited thereto, and in other examples of the present invention, the battery 43 may be coated with adhesive glue on one side of the inner bottom wall of the lower case 42, and the battery 43 may be bonded to the lower case 42 through the adhesive glue. Therefore, the battery 43 and the lower shell 42 are reliably connected, and the battery 43 is prevented from loosening due to bumping when the electric bicycle 100 runs.

The central control device 4 further comprises an antenna 45, the antenna 45 being arranged above the integrated circuit board 44 and being electrically connected to the integrated circuit board 44 for communication with the mobile terminal and/or the server. Therefore, the central control device 4 performs signal transmission with the mobile terminal by using the antenna 45, and further realizes human-computer interaction, so that shared use of the electric bicycle 100 can be satisfied.

As can be seen from the above description, the antenna 45, the integrated circuit board 44, and the battery 43 of the center control device 4 are stacked from top to bottom. The antenna 45 is located closer to the sky than the battery 43, so as to facilitate the transmission of signals, especially GPS signals, and avoid the interference of the integrated circuit board 44 and the battery 43 with the signals. The battery 43 is located closer to the ground than the antenna 45, thereby facilitating the downward movement of the center of gravity of the center control apparatus 4.

In the present embodiment, the lower case 42 and the upper case 41 are both made of plastic. Therefore, compared with the case that the upper shell 41 and the lower shell 42 are both made of metal, the influence of metal on the signal transmitted by the antenna 45 can be avoided, and the unimpeded transmission of the signal is facilitated, so that the transmission quality of the signal is improved.

Fig. 13 is a system diagram of a central control device in an embodiment of the present disclosure. As shown in fig. 13, antenna 45 may include a communication antenna 451, and communication antenna 451 may, for example, transmit signals received by processor 441 to a server, which in turn may transmit signals to the mobile terminal. In contrast, the user inputs a command on the mobile terminal, the mobile terminal transmits the command to the server, the server transmits the command to the processor 441 through the communication antenna 451, and the processor 441 performs a corresponding operation according to the received command. Of course, in other examples, processor 441 may communicate with the mobile terminal directly through communication antenna 451. Thereby, the central control device 4 performs signal transmission with the mobile terminal through the communication antenna 451, thereby realizing human-computer interaction.

It is noted that the mobile terminal may be various electronic devices having a display screen and supporting network connection, including but not limited to a smart phone, a tablet computer, and the like. The communication antenna 451 may be any one or more of a GSM antenna, a 3G antenna, a 4G antenna, or a 5G antenna, so that the processor and the server may communicate through a 2G network, a 3G network, a 4G network, and/or a 5G network; the communication antenna 451 may also be a bluetooth antenna, such that the processor 441 and the server communicate signals via bluetooth.

In order to know the position of the electric bicycle 100, the antenna 45 may further include a GPS antenna 452, the GPS antenna 452 acquires the position of the electric bicycle 100, transmits a position signal to the processor 441, and the processor 441 receives the position signal and performs an operation. When the electric bicycle 100 can be parked at any position, the processor 441 can respond to a position request instruction of the server or the mobile terminal to send the position signal received by the GPS antenna 452 to the server or the mobile terminal, and of course, the server can also perform comprehensive calculation on the position information of the GPS and the cellular network based on a fusion algorithm, so as to obtain more accurate position information. Thereby, it is convenient for the user to find and use the electric bicycle 100 through the position signal of the GPS antenna 452 or the like to thoroughly realize the free-stop free-play.

Further, when the electric bicycle 100 can only be parked at the designated parking spot, the processor 441 determines whether the electric bicycle 100 is located at the designated parking spot according to the position signal of the GPS antenna 452, and if the electric bicycle 100 is located at the designated parking spot, the processor 441 controls the motor to be stopped through the motor controller 7 (described below), otherwise, the electric bicycle 100 cannot perform a returning operation. Therefore, the electric bicycles 100 are parked at the designated parking spots, so that the operation and maintenance personnel can manage the electric bicycles 100.

Further, the GPS antenna 452 may be plural, and the frequency bands of the plural GPS antennas 452 may be the same or different. When a plurality of GPS antennas with different frequency bands are provided, the operating frequency band range of the GPS antenna 452 is large, the coverage frequency band is wide, and it is advantageous to improve the positioning accuracy. Illustratively, the number of the GPS antennas 452 is two, wherein an operating frequency band of one GPS antenna 452 is a high frequency band between 1710MHz and 2100MHz, an operating frequency band of the other GPS antenna 452 is a low frequency band, and at 880MHz to 960MHz, the GPS antenna 452 may simultaneously receive signals in 880MHz to 960MHz and signals in 1710MHz to 2100 MHz.

The antenna 45 is located above the integrated circuit board 44, and may be directly integrated on the integrated circuit board 44 or may be mounted on the integrated circuit board 44 by other components.

For example, in the example shown in fig. 4, the center control device 4 further includes an antenna holder 46, the antenna holder 46 is disposed above the integrated circuit board 44, and the antenna 45 is mounted on the antenna holder 46. By mounting the antenna 45 on the antenna bracket 46, the size limitation of the integrated circuit board 44 can be broken through, which is beneficial to the arrangement of a plurality of antennas 45, and is also beneficial to the layout of other electronic components on the integrated circuit board 44, and the mutual interference between signals transmitted between the electronic components can also be avoided. That is, by integrating the antenna 45 on the antenna support 46, the distance between the antenna 45 and the electronic components integrated on the integrated circuit board 44 is increased, and the distance between the electronic components on the integrated circuit board 44 can also be increased, so that the interference generated between the signals is reduced, and the signal transmission quality is improved.

As shown in fig. 14 and 15, the antenna mount 46 includes a substrate 461 and a side wall plate 462, and the side wall plate 462 extends from the edge of the substrate 461 to the direction of the lower integrated circuit board 44 and is supported by the integrated circuit board 44. It should be understood that the electronic components on the top surface of the integrated circuit board 44 are spaced from the bottom surface of the substrate 461 to facilitate heat dissipation and avoid damage to the electronic components.

Illustratively, the side fence 462 of the antenna bracket 46 is provided with at least one elastic catch 423, and the hook body of the elastic catch 423 is clamped with the outer edge of the integrated circuit board 44, thereby facilitating the assembly of the antenna bracket 46 and the integrated circuit board 44.

The antenna 45 may be mounted to the antenna mount 46 by adhesive bonding or may be mounted to the antenna mount 46 by screwing or clipping. For example, when the antenna 45 includes the GPS antenna 452, the substrate 461 of the antenna support 46 may have a receiving slot 463 formed thereon, and the GPS antenna 452 is engaged in the receiving slot 463.

Further, the bottom surface (i.e., the lower surface in fig. 15) of the GPS antenna 452 is coated with the adhesive, and the GPS antenna 452 is further adhered to the bottom surface of the accommodating groove 463 through the adhesive, so that the connection between the GPS antenna 452 and the antenna support 46 is reliable, and the GPS antenna 452 is prevented from being loosened due to bumping when the electric bicycle 100 travels. Similarly, when the antenna 45 comprises a GSM antenna, the GSM antenna is attached to the outer surface of the substrate 461 with adhesive.

In order to diagnose whether the braking performance of the electric bicycle 100 is abnormal or not, the signal collector may include a brake signal collector and a speed detector electrically connected to the processor through a cable, the brake signal collector is configured to detect a brake signal of the brake lever and transmit the collected brake signal to the processor, the speed detector is configured to detect a vehicle speed signal of the electric bicycle 100 and transmit the collected vehicle speed signal to the processor, the processor converts the received brake signal and the vehicle speed signal into digital signals, diagnoses whether the brake lever is failed or not according to the two signals, and transmits a diagnosis result and the two digital signals to the server. Therefore, the operation and maintenance personnel can know whether the brake performance of the electric bicycle 100 is abnormal or not according to the diagnosis result received by the server, so that corresponding measures are taken to maintain the electric bicycle 100, and the electric bicycle 100 can normally run.

For example, the brake signal collector may be a hall sensor, and the hall sensor is arranged on the brake assembly and used for detecting the stroke of the brake lever pressed during braking; the speed detector may be a speed sensor provided on the motor shaft or the wheel 2 for detecting the rotation speed of the motor shaft or the rotation speed of the wheel 2 so that the change of the vehicle speed of the electric bicycle 100 can be analyzed, or an acceleration sensor provided on the motor shaft or the wheel 2 for detecting the change of the vehicle speed of the electric bicycle 100.

The number of the brake signal collectors can be two, the two brake signal collectors are respectively arranged in the left brake crank and the right brake crank to respectively acquire brake signals of the left brake crank and the right brake crank, and therefore whether the left brake crank and the right brake crank are abnormal or not is judged independently.

Whether the brake crank fails or not is diagnosed according to the brake signal and the vehicle speed signal and is specifically configured as follows: when the pressing stroke of the brake crank is maximum and the vehicle speed is not changed, the brake crank is indicated to be invalid and the braking performance is abnormal; when the pressing stroke of the brake crank is maximum and the vehicle speed is reduced sharply, the brake crank is not invalid and the brake performance is normal; when the pressing stroke of the brake lever is large and the degree of reduction of the vehicle speed is smaller than a preset threshold value, the brake lever is abnormal and is loosened.

Therefore, the processor 441 can control the rotating speed of the motor shaft through the motor controller 7, so as to control the running speed of the electric bicycle 100, and the processor 441 and the brake component perform braking together, so that the braking effect is good.

In order to enable the user to know the information of the electric bicycle 100 so as to adjust the electric bicycle 100, in some implementations, the central control device 4 further includes a display screen, and the processor 441 is electrically connected to the display screen and transmits the information of the electric bicycle 100 to the display screen, and the display screen is used for displaying the information. Here, the information displayed on the display screen may be the remaining capacity of the battery pack, the traveling speed, the distance or the location of the electric bicycle 100, or the like. Therefore, the user can know the state of the electric bicycle 100 through the information displayed on the display screen, and then adjust the driving behavior according to the state. For example, when the display screen displays that the residual capacity of the battery pack is low, the user can reasonably adjust riding time, and great convenience is brought to the user.

Further, the electric bicycle 100 may further include a lamp 8 provided on the body 1 of the electric bicycle 100 and a lamp switch provided on the handle structure 3, the lamp 8 being electrically connected to the processor 441 through a cable, the lamp switch being used to control a connection state between the lamp 8 and the processor 441.

The electric bicycle 100 further comprises an audio player 9, the audio player 9 is electrically connected with the processor 441 through a cable, and the processor 441 is used for controlling the audio player 9 to sound according to the received signals. Thus, the user can know the relevant conditions of the electric bicycle 100 through the sound broadcasted by the audio player 9. The audio player 9 may be a speaker, a loudspeaker, etc. Illustratively, the processor controls the audio player 9 to broadcast the position of the electric bicycle 100 according to the received position signal detected by the GPS antenna 452.

In the above embodiment, the way for the processor to execute the built-in preset program, that is, to execute the one-touch returning may be: the processor controls the audio player 9 to play the first voice (e.g., while returning to the car); the processor judges whether the electric bicycle 100 is in a stop state according to the signal detected by the signal collector, if so, a returning instruction is sent to the server, if not, the audio player 9 is controlled to play a second voice (for example, the returning fails), and meanwhile, the indicator lamp 442 is controlled to emit red light and flicker for 2 seconds; the server receives the returning instruction, the processor determines whether the electric bicycle 100 meets the remote condition, that is, the processor determines whether the electric bicycle 100 is at the designated parking spot according to the position signal detected by the GPS antenna 452, and detects whether the communication antenna 451 is in normal communication, if so, the returning success information is pushed to the mobile terminal of the user, the processor controls the audio player 9 to play the third voice (for example, returning success), and controls the indicator 442 to emit green light and flash for 3 seconds, if not, the processor controls the audio player 9 to play the fourth voice (for example, the remote condition is not met), and controls the indicator 442 to emit red light and flash for 3 seconds.

The wire through hole is disposed on the bottom wall of the lower case 42, and may be located in an area enclosed by the side wall of the lower case 42 and the battery 43.

Fig. 16 is a cross-sectional view of the connection of a cable to a lower housing in an embodiment of the disclosure. As shown in fig. 11 and 16, in order to improve the sealing performance between the cable and the lower casing 42, the central control device 4 further includes an elastic clamping plate 47, a mounting hole is formed on the bottom wall of the lower casing 42, and the elastic clamping plate 47 is arranged in the mounting hole and sealed with the hole wall of the mounting hole. A plurality of wire passing holes are formed in the elastic clamping plate 47, and each cable penetrates out of one of the wire passing holes and is connected with one of the motor controller 7 or the signal collector and the like.

It should be understood that, because the outer wall of the cable usually has a rubber skin, the outer wall of the cable and the elastic clamping plate 47 both have good elasticity, so that the gap between the cable and the wire passing hole can be compensated, and the sealing performance between the cable and the lower shell 42 can be improved. This is very advantageous for sharing the vehicle, such as the electric bicycle 100, which needs to be exposed to the outdoor environment for a long time, that is, by the above arrangement, it is possible to prevent rainwater from entering the installation space from the gap to affect the working performance of the integrated circuit board 44 and the antenna 45, thereby performing a waterproof function. The elastic clamping plate 47 can be made of rubber, elastic plastic or other high-elasticity materials.

Further, a circumferential sealing groove is formed in the outer wall of the elastic clamping plate 47, and a sealing ring 471 is arranged in the circumferential sealing groove. Therefore, the sealing ring 471 seals the gap between the outer wall of the elastic clamping plate 47 and the assembling hole, so as to further improve the sealing performance between the cable and the lower shell 42.

The top (i.e. upper in fig. 16) edge of the resilient catch plate 47 extends outwardly away from its centre line to form a stop flange 472, the side of the stop flange 472 facing away from the top of the resilient catch plate 47 resting on the inner bottom wall of the lower housing 42. That is, the stop flange 472 of the resilient catch plate 47 has a larger sectional area in a direction perpendicular to the center line of the thread passing hole than the sectional area of the fitting hole in that direction. From this, avoid elastic clamping plate 47 to break away from in the mounting hole for elastic clamping plate 47 can normally work. As shown in fig. 11 and 16, the elastic clamping plate 47 is further provided with at least one fixing ear plate 473, one end of the fixing ear plate 473 is connected to the elastic clamping plate 47, the other end of the fixing ear plate 473 extends above the inner bottom wall of the lower housing 42, the fixing ear plate 473 is provided with a fixing through hole, and the lower housing 42 is provided with an insertion post at a position corresponding to the fixing through hole, the insertion post being inserted into the fixing through hole.
