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.

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.

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.

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.

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.

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.

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.

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.

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.
