Description

Technical Field

[0001] The present invention relates to the technical field of non-motor vehicles, and in particular to a braking system for non-motor vehicles and a control method thereof. Background Art

[0002] At present, the hydraulic brake device adopts a brake caliper connected to the edge of the brake disc of the wheel. An oil cylinder is arranged in the brake caliper, and a brake pad is arranged on the output end face of the oil cylinder. By pulling the brake handle, the oil cylinder is supplied with oil, thereby driving the brake pad to close to the brake disc, thereby applying friction to achieve the braking effect.

[0003] However, the hydraulic brakes of non-motor vehicles in the prior art usually use a single cylinder with a larger stroke. When the user slightly pulls the brake handle, the single cylinder can be supplied with oil, but its output stroke is not enough to achieve the braking effect, and the braking effect is poor.

[0004] Another non-motor vehicle hydraulic brake in the prior art adopts a four-cylinder method, with two cylinders arranged on each side of the brake disc, thereby increasing the effective area of ​​the brake pad. However, in this solution, the user needs a larger stroke when pulling the handle. In other words, the user needs to apply a larger pulling force to achieve the braking effect. However, the two cylinders act on the brake application member at the same time, and the instantaneous braking effect is too large.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0054] like Figure 1-11As shown, a braking system for a non-motor vehicle comprises:

[0055] An oil supply assembly, for providing a braking driving force, having an operating member 10 for controlling an oil supply amount;

[0056] The brake housing 1 is relatively arranged on both sides of the brake disc 13 of the driving wheel 14, and a brake driving component is provided in the brake housing 1, which is opened toward the brake disc 13 and receives the oil pressure;

[0057] A brake actuator 4 is disposed between the brake housings 1 and receives the brake drive assembly and has a friction surface for contacting the brake disc 13 and applying a braking force;

[0058] The brake drive assembly includes a plurality of brake drive units arranged on the brake housing 1 on the same side, and a plurality of oil grooves 1.1 for accommodating the brake drive units. The maximum oil carrying capacity of the plurality of brake drive units in their oil grooves 1.1 increases successively, so that the brake drive units abut against the brake application member 4 in sequence as the operating member 10 moves.

[0059] As a further embodiment of the brake drive assembly, the brake drive assembly includes a first brake unit 2 and a second brake unit 3 arranged on the brake housing 1 on the same side, and the first brake unit 2 and the second brake unit 3 can both withstand oil pressure and thus extend relative to the brake actuator 4, thereby applying a force on the brake actuator 4 to clamp the brake disc 13, wherein the maximum oil capacity of the first brake unit 2 in its oil groove 1.1 is smaller than that of the second brake unit 3, so that when the operating member 10 is pulled to a certain extent, the first brake unit 2 can be extended before the second brake unit 3, and the second brake unit 3 is relatively extended by a stroke under the action of oil pressure to reduce the gap 1.2 between the second brake unit 3 and the brake actuator 4, so as to increase the response speed of the second brake unit 3 when the operating member 10 is further pulled.

[0060] During the braking process, the user can pull the operating member 10 with a smaller stroke to extend the first brake unit 2, so that the parts of the brake assembly corresponding to the first brake unit 2 are close to each other, achieving a preliminary braking effect. At the same time, the second brake unit 3 is close to each other by a stroke under the above action, thereby reducing the gap 1.2 between the part of the brake assembly corresponding to the second brake unit 3 and the brake disc 13 of the non-motor vehicle, so that when the user further pulls the operating member 10, the second brake unit 3 and the brake assembly can quickly act on the brake disc 13, achieving a phased braking effect.

[0061] It should be pointed out that the present invention is not limited to the above-mentioned first brake unit 2 and second brake unit 3. If there is enough space, a third brake unit or even a fourth brake unit can be provided to improve the multi-stage effect of the braking force, and the response speed of each stage of the brake unit is also gradually improved to meet the braking force requirements under different circumstances.

[0062] In other embodiments, a more optimized braking effect is desired, and brake units with different diameters are provided on the brake housing 1 on both sides.

[0063] Preferably, the effective area of ​​the first brake unit 2 is smaller than the effective area of ​​the second brake unit 3, that is, the effective area of ​​each level of the above-mentioned brake unit on the brake element 4 increases step by step to further improve the braking effect that each level of the brake unit can provide.

[0064] like Fig.11 As shown, as a further explanation of the action of the multi-stage brake unit, the oil supply assembly can apply at least a first oil supply amount and a second oil supply amount to the brake drive assembly through the action of the operating member 10. Under the first oil supply amount, the first brake unit 2 is actuated and presses the actuating member 4 to the brake disc 13, and the second brake unit 3 extends toward the brake application member 4, thereby reducing the gap 1.2 between the second brake unit 3 and the brake application member 4. In addition, under the first oil supply amount, the portion of the brake application member 4 corresponding to the first brake unit 2 can be effectively pressed against the brake disc 13, and the portion of the brake application member 4 away from the first brake unit 2 is opposite, or at least partially in contact with the brake disc 13, thereby providing a certain drag force, so that when the subsequent brake unit reaches the working stroke, it can quickly apply force to the brake application member 4 and the brake disc 13;

[0065] Under the second oil supply, the first brake unit 2 remains in the current position, and the second brake unit 3 reaches the working stroke and presses the actuating member 4 against the brake disc 13 to achieve a secondary braking effect. Obviously, through further action of the operating member 10, the second oil supply is greater than the first oil supply.

[0066] In other embodiments, for electric non-motor vehicles, the drive wheel 14 is connected to a power supply system 12. In order to reduce energy loss during braking and prevent the user from performing power supply operations during braking, a power-off sensing component 11 is also connected to one side of the operating member 10. The power-off sensing component 11 can receive the braking signal from the operating member 10 to disconnect the power supply system 12 to achieve rapid braking. Under the action of the above-mentioned multi-stage braking unit, the user can drive the operating member 10 at a smaller rotation angle to achieve stable and reliable braking force.

[0067] As a further embodiment of the power-off sensing component 11, a magnetic block 11.2 is transmission-connected to the operating member 10. The magnetic block 11.2 is displaced as the operating member 10 moves, and controls the power-off sensing component 11 to be connected or disconnected. Through the connection or disconnection of the power-off sensing component 11, a power-off signal is generated to the power supply system 12.

[0068] like Fig.10 As shown, specifically, the power-off sensing component 11 refers to the reed switch 11.1. A magnetic block 11.2 is provided in the valve component 10.5. The magnetic block 11.2 can be displaced relative to the reed switch 11.1 along with the valve component 10.5 under the action of the handle body 10.2, thereby controlling the on and off of the switch spring 4.1 in the reed switch 11.1, and then outputting a braking signal to the power supply system 12 to disconnect the power supply of the power supply system 12.

[0069] In other embodiments, the magnetic block 11.2 may also be disposed on the handle body 10.2, so that the handle body 10.2 is moved relative to the reed switch 11.1 to obtain a braking signal.

[0070] like Figure 7 As shown, as an option, the power-off sensing component 11 includes an adjustable adjustment block 11.3 arranged on the bracket body 10.1, the reed switch 11.1 is fixed on the bracket body 10.1 through the adjustment block 11.3, and the adjustment block 11.3 is provided with an adjustment slot 11.4, the adjustment block 11.3 is fixed to the bracket body 10.1 by passing bolts through the adjustment slot 11.4, so as to achieve the adjustment of the initial position of the power-off sensing component 11 relative to the magnetic block 11.2.

[0071] Through the above improvements, the electric vehicle can be powered off by the action of the handle body 10.2 to avoid the loss caused by continuous power supply during braking. In addition, the control gear of the power-off sensing component 11 can be set according to different needs.

[0072] As a further embodiment of the oil supply assembly, the oil supply assembly includes a bracket body 10.1, and a handle body 10.2 rotatably arranged on the bracket body 10.1, an oil supply chamber 10.3 is provided on one side of the bracket body 10.1, and a valve chamber 10.4 connected to the oil supply chamber 10.3 is provided in the handle body 10.2, the valve chamber 10.4 is connected to the oil tank 1.1 of the multi-stage drive unit through an oil supply pipeline 5, and a valve assembly 10.5 is connected to one end of the handle body 10.2 close to its rotating shaft through a ball head connector, and the valve assembly 10.5 slides in the valve chamber 10.4 in a sealed manner through an oil seal connector, so that the sliding of the valve assembly 10.5 is controlled by the handle body 10.2, and the oil supply is controlled by the relative position of the valve assembly 10.5 in the valve chamber 10.4 to achieve the output of the braking force.

[0073] The operating member 10 is a brake handle body 10.2 for supplying oil and pressure.

[0074] Among them, the above-mentioned oil supply pipeline 5 is connected to the brake housing 1, and the brake housing 1 is provided with an oil supply channel connected to the oil supply pipeline 5, a first oil supply channel 5.1 connected to the oil supply channel, and a second oil supply channel 5.2 connected to the first oil supply channel 5.1. The first oil supply channel 5.1 is connected to a plurality of oil grooves 1.1 in the brake housing 1 on one side, and the second oil supply channel 5.2 is connected to a plurality of oil grooves 1.1 in the brake housing 1 on the other side.

[0075] like Figure 3 and Figure 4 As shown, according to the above-mentioned embodiment, the brake housing 1 includes a first housing connected to the oil supply pipeline 5, and a second housing connected to the first housing, wherein the first oil supply channel 5.1 is arranged in the first housing, and the second oil supply channel 5.2 is arranged on the second housing, the first oil supply channel 5.1 extends with respect to the oil supply pipeline 5 and enters into the first housing, and the path of the first oil supply channel 5.1 passes through the oil groove 1.1 of the first brake unit 2 and the second brake unit 3, thereby realizing the connection between the first brake unit 2 and the second brake unit 3.

[0076] As a variation of the connection method within the first housing, the first oil supply pipeline 5 is directly connected to the first brake unit 2, and a gap 1.2 for the oil supply passage is provided between the oil grooves 1.1 of the first brake unit 2 and the second brake unit 3, or the first oil supply pipeline 5 is directly connected to the second brake unit 3, and a gap 1.2 for the oil supply passage is provided between the oil grooves 1.1 of the first brake unit 2 and the second brake unit 3.

[0078] Furthermore, the second oil supply channel 5.2 includes a first branch 5.21 and a second branch 5.22. The first branch 5.21 extends in the first shell vertically or at a certain angle relative to the first oil supply channel 5.1, and extends through the first shell into the second shell. The first branch 5.21 is sealed by an oil seal screw, and the second branch 5.22 extends toward the oil groove 1.1 in the second shell vertically or at a certain angle relative to the first branch 5.21, thereby realizing oil circuit communication in the second shell.

[0079] As another implementation of the oil circuit connection of the multi-stage brake unit, a gap 1.2 for oil to pass through is provided between the containers where adjacent brake units are located.

[0080] In other embodiments, the valve chamber 10.4 is connected to two independent oil supply pipelines 5, and the two independent oil supply pipelines 5 are respectively connected to the corresponding brake housings 1, so as to supply oil to the brake units in the brake housings 1 respectively, so as to improve the action sensitivity of the brake units. Compared with a single oil supply pipeline 5, the damping feeling is further improved to ensure the user's operating feel.

[0081] It should be pointed out that no matter which connection method is used, the volume and diameter specifications of the relative cylinder units must be consistent.

[0082] Among them, the brake housing 1 is provided with an oil groove 1.1 for accommodating the brake unit. The brake unit has at least two cylinder units consisting of a sealing rubber ring confined in the oil groove 1.1 and a piston unit axially movable relative to the sealing rubber ring. The piston unit matches its corresponding inner cavity of the oil groove 1.1.

[0083] like Figure 5 As shown, as a further embodiment of the brake member 4, the brake member 4 provides a force away from the brake disc 13 through a spring sheet 4.1, wherein:

[0084] The spring piece 4.1 is fork-mounted in a V-shape, and its upper end is fixed between two opposite brake housings 1 by a latch, and its lower end has an extension arm 4.11 extending toward the inner side of the brake housing 1. The extension arm 4.11 is fork-mounted and receives the brake actuator 4, and is used to apply a force to the brake actuator 4 to move away from each other through the elastic force of the spring piece 4.1 after the brake is released;

[0085] The brake actuator 4 is relatively arranged between the brake housings 1, and its back receives the piston unit of the brake unit so as to approach each other through the output action of the brake unit. A brake portion 4.2 is provided on the opposite part of the brake actuator 4, and steps are formed on at least two sides of the brake actuator 4, and the steps are used for the extension arm 4.11 of the spring sheet 4.1 to be placed therein, so as to ensure the stability of the engagement between the spring sheet 4.1 and the brake actuator 4.

[0086] A through hole is provided on the brake member 4 corresponding to the upper end of the spring sheet 4 . 1 for the above-mentioned latch to pass through, thereby limiting the relative position of the brake member 4 .

[0087] like Figures 1 to 3 As shown, the brake actuator 4 includes a brake portion 4.2 inserted between the brake housings 1 and a heat dissipation portion extending outside the brake housings 1. The brake portion 4.2 is used to contact the brake disc 13 and generate braking force. A plurality of heat dissipation fins 4.21 are provided on the heat dissipation portion.

[0088] Specifically, the heat sinks 4.21 are arranged in an inclined shape, and the heat sinks 4.21 are arranged on both sides of the heat dissipation part, and the braking part 4.2 extends out of the heat sink 4.21 on the same side. Through the above improvements, the heat dissipation effect of the brake actuator 4 is improved to ensure the braking force.

[0089] Preferably, two brake drive units are coaxially arranged on the two brake housings 1 so that both sides of the brake disc 13 can obtain stable braking force, avoiding the staggered force of the cylinder unit, which causes shear force on the brake disc 13 and affects the stability of braking.

[0097] Solenoid valve 6.1, which is arranged between the oil tank 1.1 and the valve chamber 10.4 to control the on-off of the return line 6.8;

[0098] The oil supply detection unit 6.2 is used to detect the action of the operating member 10 or the oil pressure in the oil supply pipeline 5, and output a first brake signal to ensure that the brake drive assembly is working, that is, in a braking state;

[0099] Angular velocity detection unit 6.3 and wheel speed sensor, angular velocity detection unit 6.3 is used to detect the relative rotation of the driving wheel 14 and output a second braking signal, the wheel speed sensor is arranged on one side of the driving wheel 14 to detect the deceleration of the driving wheel 14, so as to determine whether the driving wheel 14 is in a locked state

[0100] The solenoid valve 6.1 is configured to be energized after receiving the first brake signal and the second brake signal to release the oil pressure in the oil tank 1.1 to the return channel;

[0101] The pump unit 6.5 is arranged on the return channel, and the pump unit 6.5 is configured to be energized after receiving the first brake signal and the second brake signal to output the oil pressure in the oil tank 1.1 to the valve chamber 10.4.

[0102] Preferably, the electromagnetic generator is arranged between the oil tank 1.1 and the pump body to ensure that during normal braking, the valve chamber 10.4 maintains one-way communication with the oil tank 1.1.

[0103] In other embodiments, a solenoid valve 6.1 may also be provided between the valve chamber 10.4 and the pump body to ensure that the valve chamber 10.4 maintains one-way communication with the oil tank 1.1 during normal braking.

[0104] The angular velocity sensor, the rotation speed sensor 6.4 and the oil supply detection unit 6.2 feed back detection signals to the controller 6.6, and the controller 6.6 sends power-on control signals to the solenoid valve 6.1 and the pump unit 6.5.

[0105] The above wheel speed sensor is a sensor in a conventional ABS anti-lock braking system in the prior art, and will not be described in detail here.

[0106] Through the above improvements, when it is detected that the driving wheel 14 is approaching or in a locked state, the oil pressure in the oil tank 1.1 can be released through the reflux channel, and the reflux channel can bear the oil pressure to make the above-mentioned brake unit relatively return a stroke. At the same time, the pump unit 6.5 is energized and starts working, driving the oil in the reflux channel to re-enter the valve chamber 10.4. At this time, the reflux oil re-enters the oil tank 1.1 of the above-mentioned brake unit through the oil supply line 5, so that the brake unit is re-extended and pressed against the brake application member 4, realizing the reciprocating movement of the brake application member 4 relative to the brake disc 13, thereby avoiding the locking of the driving wheel 14.

[0107] Specifically, the anti-lock braking assembly 6 further includes a power supply 6.7 and a controller 6.6, and the solenoid valve 6.1, the oil supply detection unit 6.2, the angular velocity detection unit 6.3, the wheel speed sensor, and the pump unit 6.5 are all controlled by the controller 6.6 and the power supply 6.7.

[0108] As an option, the pump unit 6.5 and the solenoid valve 6.1 can be arranged on the frame of the non-motor vehicle, and the return channel can be connected and connected through an independently arranged oil pipe.

[0109] Preferably, oil is reserved in the reflux channel to increase the reciprocating response speed of the brake actuator 4 under the anti-lock braking effect.

[0110] Preferably, the side of the pump unit 6.5 adjacent to the oil groove 1.1 is flared, and the side of the pump unit 6.5 adjacent to the valve chamber 10.4 is closed, so as to increase the flow rate of the oil returning to the valve chamber 10.4 through the Venturi effect, thereby improving the reciprocating action response speed of the brake actuator 4 under the anti-lock action.

[0111] like Fig.13As shown, in other embodiments, the brake drive assembly also includes an auxiliary housing 7 arranged on both sides of the brake disc 13 away from the brake housing 1, an electromagnet 8 movably arranged in the auxiliary housing 7, an auxiliary brake member 9 connected to the electromagnet 8, and at least one electromagnet 8 is connected to an inverter 8.1. The above-mentioned electromagnet 8 and inverter 8.1 are powered by a power supply 6.7 and controlled by the above-mentioned controller 6.6. When the brake unit fails to function, the braking force is applied by the auxiliary stop member.

[0112] During normal driving, the electromagnets 8 on both sides are powered off, and the auxiliary brake member 9 does not brake;

[0113] During normal braking, the electromagnets 8 are energized to attract each other, thereby forcing the auxiliary brake member 9 to act on the brake disc 13. This process can be performed before the first brake unit 2 reaches the working stroke, that is, the rotation angle of the operating member 10 is less than the above-mentioned first angle;

[0114] During the anti-lock operation, the inverter 8.1 controls the electromagnet 8 on one side to change the current direction back and forth, thereby causing the electromagnets 8 on both sides to attract or repel back and forth, thereby achieving the reciprocating pressing and moving away of the auxiliary brake member 9 relative to the brake disc 13 to assist the above-mentioned anti-lock component 6.

[0115] The present invention also provides a control method for a braking system for a non-motor vehicle, comprising the above-mentioned braking system for a non-motor vehicle, and specifically comprising the following steps:

[0117] S2: primary braking stage: further pull the operating member 10, the oil supply assembly outputs the second oil supply amount Q2, the first brake unit 2 and the second brake unit 3 receive the second oil supply amount, and the first brake unit 2 presses the actuating member 4 to contact the brake disc 13, the second brake unit 3 further acts, and forms a third gap 1.2D3 with the brake actuating member 4, wherein D3 is smaller than D2;

[0118] S3 secondary braking stage: the operating member 10 is further pulled, the oil supply assembly outputs the third oil supply amount Q3, the first brake unit 2 and the second brake unit 3 receive the third oil supply amount, and the first brake unit 2 keeps pressing the actuating member 4 to contact the brake disc 13, and the second brake unit 3 further moves and presses the brake actuating member 4;

[0119] S4 anti-lock stage: the oil supply detection unit 6.2 detects that the oil supply component is in the oil pressure supply state to ensure that the oil tank 1.1 is in the oil pressure input state, and the angular velocity detection unit 6.3 and the speed sensor 6.4 detect the deceleration of the drive wheel 14 to determine whether the drive wheel 14 is in a locked or close to locked state. At this time, the solenoid valve 6.1 is turned on to release the oil pressure in the oil tank 1.1 into the reflux channel, and the pump unit 6.5 works and drives the oil pressure in the reflux channel into the valve chamber 10.4, so that the oil pressure reciprocates in the oil tank 1.1, forcing the brake unit to reciprocate on the brake application member 4.

[0120] Before the first braking phase in step S2, the method further includes:

[0121] In step X, in the auxiliary braking stage, electromagnets 8 are arranged on both sides of the brake disc 13, and the electromagnets 8 are fixedly connected to the auxiliary brake member 9. The operating member 10 is controlled to rotate to a fourth angle, which is smaller than the first angle. The electromagnets 8 are energized and attracted to each other, and the auxiliary brake member 9 acts on the brake disc 13 to perform auxiliary braking.

[0122] In the anti-lock braking stage of step S4, it also includes:

[0123] In the auxiliary anti-lock braking stage of step Y, the electromagnet 8 on one side is connected to the inverter 8.1, and the electromagnet 8 on the other side remains energized. The controller 6.6 detects that the drive wheel 14 is in or close to being locked through the above-mentioned angular velocity sensor, speed sensor 6.4 and oil supply detection unit 6.2. The controller 6.6 controls the power supply 6.7 and the inverter 8.1 to output a forward current signal or a reverse current signal at intervals to control the electromagnet 8 on one side and the electromagnet 8 on the other side to attract or repel each other, so that the auxiliary brake member 9 acts reciprocatingly on the brake disc 13.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed.
