Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of a brake control system of an electric vehicle provided in the prior art, and as shown in fig. 1, the brake control system of the prior art includes a left brake lever 110 and a right brake lever 120 connected in parallel, that is, a first end of the left brake lever 110 and a first end of the right brake lever 120 are connected together, and both the first end of the left brake lever 110 and the first end of the right brake lever 120 are connected to a brake signal terminal a of a controller 130; the second end of the left lever 110 and the second end of the right lever 120 are connected together, and the second end of the left lever 110 and the second end of the right lever 120 are both connected to the control end B of the controller 130.
Wherein, the left brake lever 110 and the right brake lever 120 can both control the rear wheel of the electric vehicle to generate electric braking. Since the left brake lever 110 and the right brake lever 120 are connected in parallel, when a user pinches off any brake lever or pinches off two brake levers at the same time (any brake lever is conducted or conducted at the same time), the brake signal generated by the control terminal B of the controller 130 can be transmitted to the brake signal terminal a of the controller 130, so that no matter the left brake lever 110 is conducted or the right brake lever 120 is conducted, the brake signal transmitted to the brake signal terminal a of the controller 130 is the same, and the intensity of electric braking generated by controlling the rear wheel of the electric vehicle by pinching off any brake lever or pinching off two brake levers at the same time by the controller 130 is the same.
The strength of the electric brake of the current electric vehicle is set before the factory shipment and cannot be changed. If the set electric brake is weak, the experience is not good and no brake sense exists in the actual use process; if the set electric brake is strong, the situation of slipping in rainy and snowy weather may exist in the actual use process. For example, the user riding the electric vehicle still keeps the habit of riding the bicycle, i.e. often pinch the left brake lever 110 to brake the rear wheel of the vehicle. Because the mechanical brake and the electric brake of the left brake lever 110 are both arranged on the rear wheel of the electric vehicle, when the left brake lever 110 is pinched to make the vehicle brake emergently in case of emergency, the rear wheel can simultaneously perform the mechanical brake and the electric brake, and if the brake strength is too high, the safety is easily influenced by slipping in rainy and snowy weather; if the braking strength is too low, effective braking cannot be realized.
In order to solve the problem of single braking strength of the conventional electric vehicle, the utility model designs an electric vehicle braking control system with electric braking of multiple strengths. Fig. 2 is a schematic structural diagram of a brake control system of an electric vehicle according to the present invention. As shown in fig. 2, the brake control system for an electric vehicle includes: a first brake receiving module 210, a second brake receiving module 220, a control module 230, and a power module 240; the first end of the first brake receiving module 210 is connected to the first brake signal input terminal X1 of the control module 230, the second end is connected to the control signal output terminal Y of the control module 230, and the first brake receiving module 210 is configured to control a conduction state between the control signal output terminal Y and the first brake signal input terminal X1 according to a brake action of a user; the first end of the second brake receiving module 220 is connected to the second brake signal input terminal X2 of the control module 220, the second end is connected to the control signal output terminal Y of the control module 230, and the second brake receiving module 220 is configured to control a conduction state between the control signal output terminal Y and the second brake signal input terminal X2 according to a brake action of a user; the control module 230 is configured to control different levels of electric braking signals output by the electric braking signal output terminal N according to whether the control signal is input to the first brake signal input terminal X1 and the second brake signal input terminal X2; the input end of the power module 240 is connected to the electric brake signal output end N of the control module 230, and the power module 240 is configured to perform electric braking according to the electric brake signal, wherein the electric brake strengths of the power module 240 under different levels of electric brake signals are different.
The first brake receiving module 210 and the second brake receiving module 220 are control switches of a brake system of an electric vehicle, for example: the first brake receiving module 210 may be a left brake lever, and the second brake receiving module 220 may be a right brake lever. A user controls the conduction state of the first brake receiving module 210 through a braking action acting on the first brake receiving module 210, thereby indirectly controlling the information transmission state connected to both ends of the first brake receiving module 210; the user controls the on state of the second brake receiving module 220 through a braking action applied to the second brake receiving module 220, thereby indirectly controlling the information transmission state connected to both ends of the second brake receiving module 220. The control module 230 is a control core of the braking system of the electric vehicle, and can output a corresponding electric braking signal according to the conduction state of the first brake receiving module 210 and the conduction state of the second brake receiving module 220. The power module 240 is an executing device of a brake system of the electric vehicle, and can execute electric braking with corresponding strength according to the electric braking signal output by the control module 230.
Specifically, a first end of the first brake receiving module 210 is connected to a first brake signal input terminal X1 of the control module 230, and a second end of the first brake receiving module 210 is connected to a control signal output terminal Y of the control module 230. A first terminal of the second brake receiving module 220 is connected to the second brake signal input terminal X2 of the control module 230, and a second terminal of the second brake receiving module 220 is connected to the control signal output terminal Y of the control module 230. The input of the power module 240 is connected to the electric brake signal input of the control module 230.
For example, based on the above connection relationship, when the first brake receiving module 210 is turned on (for example, a user pinches a left brake lever), the first brake signal input terminal X1 of the control module 230 can receive the control signal generated by the control signal output terminal Y of the control module 230; the first brake receiving module 210 is not conductive (e.g., the user releases the left brake lever), and the first brake signal input terminal X1 of the control module 230 cannot receive the control signal generated by the control signal output terminal Y of the control module 230. When the second brake receiving module 220 is turned on (for example, a user pinches a right brake lever), the second brake signal input terminal X2 of the control module 230 can receive a control signal generated by the control signal output terminal Y of the control module 230; the second brake receiving module 220 is not conductive (e.g., the user releases the right brake lever), and the second brake signal input terminal X2 of the control module 230 cannot receive the control signal generated by the control signal output terminal Y of the control module 230. The control module 230 may control the self electrical braking signal output terminal N to output three different levels of electrical braking signals according to whether the control signal is input from the first brake signal input terminal X1 and the second brake signal input terminal X2, that is, the control module 230 may control the self electrical braking signal output terminal N to output three different levels of electrical braking signals according to the conduction states of the first brake receiving module 210 and the second brake receiving module 220. Specifically, when the first brake receiving module 210 is turned on and the second brake receiving module 220 is turned off, the electric brake signal output terminal N of the control module 230 outputs a level of electric brake signal to the power module 240. When the first brake receiving module 210 is not turned on and the second brake receiving module 220 is turned on, the electric brake signal output terminal N of the control module 230 outputs a level of electric brake signal to the power module 240. When the first brake receiving module 210 is turned on and the second brake receiving module 220 is also turned on, the electric brake signal output terminal N of the control module 230 outputs a level of electric brake signal to the power module 240. The levels of the output electric brake signals in the above three cases are different, and the electric brake strengths of the power module 240 under the electric brake signals of different levels are different.
According to the technical scheme of the embodiment of the utility model, the first brake receiving module is used for controlling the conduction state between the control signal output end and the first brake signal input end according to the brake action of the first brake receiving module per se; the second brake receiving module is used for controlling the conduction state between the control signal output end and the second brake signal input end according to the brake action of the user; the control module is used for controlling electric braking signals of different grades output by the electric braking signal output end of the control module according to whether the first braking signal input end and the second braking signal input end input control signals or not; the power module is used for carrying out electric braking with different intensities according to electric braking signals with different grades. Therefore, a user can control the first brake receiving module and the second brake receiving module differently to enable the control module to output electric braking signals of different levels, so that the power module can execute electric braking with different intensities, and the user can select electric braking with different intensities in use.
Optionally, the control module is configured to output a first-level electric braking signal through the electric braking signal output terminal when the control signal is input at the first braking signal input terminal and the control signal is not input at the second braking signal input terminal; the control module is used for outputting a second-level electric braking signal through the electric braking signal output end when the first braking signal input end does not input a control signal and the second braking signal input end inputs the control signal; the control module is used for outputting a third-level electric braking signal through the electric braking signal output end when the control signal is input from the first braking signal input end and the control signal is input from the second braking signal input end; the power module is used for braking with first electric braking strength according to the first-grade electric braking signal; the power module is used for braking with second electric braking strength according to the second-grade electric braking signal; and the power module is used for braking with third electric braking strength according to the third-grade electric braking signal.
The control module can output electric braking signals of different grades, and the control module can select the electric control signals of different grades according to the specific condition that the first braking signal input end and the second braking signal input end receive the control signals. The power module may output electric brakes of different strengths, and the strength of the electric brakes performed by the power module is related to the level of electric brake signals received by the power module. For example: when the first brake receiving module is switched on and the second brake receiving module is not switched on, the first brake signal input end of the control module can receive a control signal generated by the control signal output end of the control module, and the second brake signal input end of the control module cannot receive a control signal generated by the control signal output end Y of the control module. At the moment, the electric braking signal output end of the control module outputs a first-grade electric braking signal to be transmitted to the power module, and the power module correspondingly executes braking with first electric braking strength according to the first-grade electric braking signal. When the first brake receiving module is not conducted and the second brake receiving module is conducted, the first brake signal input end of the control module cannot receive the control signal generated by the control signal output end of the control module, and the second brake signal input end of the control module can receive the control signal generated by the control signal output end of the control module. At the moment, the electric braking signal output end of the control module outputs a second-level electric braking signal to be transmitted to the power module, and the power module correspondingly executes braking with second electric braking strength according to the second-level electric braking signal. When the first brake receiving module is switched on and the second brake receiving module is switched on, the first brake signal input end of the control module can receive a control signal generated by the control signal output end of the control module, and the second brake signal input end of the control module can also receive a control signal generated by the control signal output end of the control module. At the moment, the electric braking signal output end of the control module outputs a third-level electric braking signal to the power module, and the power module correspondingly executes braking of third electric braking strength according to the third-level electric braking signal. (Note that the electric brake intensities corresponding to the electric brake signals of different grades are preset, and the electric brake intensities corresponding to the electric brake signals of different grades are different.)
Optionally, the first level electric brake signal is a first level voltage signal; the second-level electric braking signal is a second-level voltage signal; the third-level electric braking signal is a third-level voltage signal; the power module is used for braking with first electric braking strength according to the first grade voltage signal; the power module is used for braking the second electric braking strength according to the first grade voltage signal; and the power module is used for braking the third electric braking strength according to the first grade voltage signal.
The electric brake signal may be a voltage signal, that is, the electric brake signals of different levels are voltage signals of different levels. The power module can brake with different intensities according to the voltage signals with different grades, namely the control module can control the power module to brake with different intensities through the voltage signals with different grades. The control module outputs a first-level electric braking signal which is a first-level voltage signal, and the control module controls the power module to brake with first electric braking strength through the first-level voltage signal. The second-level electric braking signal output by the control module is a second-level voltage signal, and the control module controls the power module to brake at a second electric braking strength through the second-level voltage signal. The third-level electric braking signal output by the control module is a third-level voltage signal, and the control module controls the power module to brake at a third electric braking intensity through the third-level voltage signal.
Fig. 3 is a schematic structural diagram of another electric vehicle brake control system provided by the utility model. As shown in fig. 3, the electric vehicle brake control system further includes a first mechanical braking module 250 and a second mechanical braking module 260, wherein the first mechanical braking module 250 is configured to perform mechanical braking on a first wheel of the electric vehicle after the first brake receiving module 210 receives a braking action of a user, and the second mechanical braking module 260 is configured to perform mechanical braking on a second wheel of the electric vehicle after the second brake receiving module 220 receives the braking action of the user.
The electric vehicle brake control system further has a first mechanical brake module 250 and a second mechanical brake module 260. Specifically, the first mechanical braking module 250 is installed at a first wheel of the electric vehicle (for example, a rear wheel of the electric vehicle), and after the first brake receiving module 210 receives a braking action of the user, the first mechanical braking module 250 performs a band-type brake on the first wheel of the electric vehicle. The second mechanical braking module 260 is installed on a second wheel of the electric vehicle (for example, a front wheel of the electric vehicle), and after the second brake receiving module 220 receives a braking action of the user, the second mechanical braking module 260 performs a brake application on the second wheel of the electric vehicle.
Optionally, the power module is configured to electrically brake the first wheel according to the electric brake signal; the first electric braking strength is less than the second electric braking strength; the second electric brake intensity is less than the third electric brake intensity.
The first wheel of the electric vehicle is a rear wheel, and the second wheel of the electric vehicle is a front wheel. The electric vehicle brake control is realized by matching electric brake control and mechanical brake control, and a power module of the electric brake control electrically brakes the rear wheel of the electric vehicle according to an electric brake signal. After the first mechanical braking module of the mechanical brake receives the braking action of the user (for example, the user pinches a left brake handle) through the first brake receiving module, the first mechanical braking module carries out band-type brake braking on the rear wheel of the electric vehicle. After the second mechanical braking module of the mechanical brake receives the braking action of the user (for example, the user pinches the right brake handle) through the second brake receiving module, the second mechanical braking module carries out band-type braking on the front wheel of the electric vehicle. The first electric braking intensity of the power module on the first wheel of the electric vehicle is smaller than the second electric braking intensity of the power module on the first wheel of the electric vehicle, and the second electric braking intensity of the power module on the first wheel of the electric vehicle is smaller than the third electric braking intensity of the power module on the first wheel of the electric vehicle. Therefore, the first electric brake is low in strength, and the situation that the electric brake and the mechanical brake of the rear wheel are overlarge in superposition and slip when a user only pinches the left brake crank can be prevented. The second electric brake intensity that sets up is slightly bigger, and the user only carries out mechanical braking, the rear wheel carries out slightly bigger electric brake when pinching right brake lever, because two wheels all are slowing down around, can reduce the risk of skidding effectively. The third electric brake has the maximum strength, so that a user can pinch the brake with two hands in an emergency, and the vehicle can be braked as soon as possible by matching with mechanical brake under the larger electric brake.

As shown in fig. 4, the first brake receiving module includes a first switch 211; a first terminal of the first switch 211 serves as a first terminal of the first brake receiving module, and a second terminal of the first switch 211 serves as a second terminal of the first brake receiving module.

Optionally, with continued reference to fig. 4, the second brake receiving module includes a second switch 221; a first terminal of the second switch 221 serves as a first terminal of the second brake receiving module, and a second terminal of the second switch 221 serves as a second terminal of the second brake receiving module.

Specifically, a first terminal of the second switch 221 serves as a first terminal of the second brake receiving module, that is, the first terminal of the second switch 221 is connected to the second brake signal input terminal X2 of the control module 230. A second terminal of the second switch 221 serves as a second terminal of the second brake receiving module, that is, the second terminal of the second switch 221 is connected to the control signal output terminal Y of the control module 230. The second switch 221 may control the on state of the second switch 221 to be in an open state and an on state according to a braking action on which a user acts).

The electric braking signal output end of the control module 230 controls the motor 241 to rotate by outputting different levels of voltage signals, and the rotating speeds of the motor 241 are different under the different levels of voltage signals, so that different electric braking strengths executed by the motor 241 are realized.
