[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 to Figure 4 As shown, a device for controlling automobile brakes and clutches based on an electric push rod of the present invention comprises a fixed bracket 1, to which an electric push rod housing 2 is fixedly connected, and a clutch electric push rod 4 and a brake electric push rod 12 are installed on the electric push rod housing 2; it also comprises a secondary clutch connecting rod 6 and a secondary brake connecting rod 7, one end of the secondary clutch connecting rod 6 is connected to the main clutch pedal in the main driving, and the other end of the secondary clutch connecting rod 11 is connected to the secondary clutch pedal 11, the secondary brake connecting rod 7 is connected to the main brake pedal in the main driving, and the other end of the secondary brake connecting rod 7 is connected to the secondary brake pedal 15; the free end of the clutch electric push rod 4 is fixedly connected to a first pin 5, and the secondary clutch connecting rod 6 is rotatably connected to a first connecting member 8, the first pin 5 abuts against the first connecting member 8, and the first connecting member 8 is connected to a pressure block 9, and the pressure block 9 is connected to the secondary clutch pedal 11;

[0026] In this embodiment, the clutch electric push rod 4 is in an extended state by default. When the clutch electric push rod 4 is instructed to perform clutch, the free end of the clutch electric push rod 4 contracts, and the first pin 5 connected to the end of the clutch electric push rod 4 drives the first connecting member 8 to rotate (from Figure 1 The direction shown is counterclockwise rotation), the first connecting member 8 drives the secondary clutch pedal 11 to press down through the pressing block 9, which is consistent with the action of a person's foot pressing down on the clutch pedal; when the free end of the clutch electric push rod 4 is instructed to retract, the first pin 5 connected to the clutch electric push rod 4 will lose its effect on the first connecting member 8, and the secondary clutch pedal 11 will return to the initial state under the action of its own rebound force, and the clutch is released;

[0027] Because the first pin 5 and the first connecting member 8 are in floating connection, when the co-pilot has a trainer, manually stepping on the secondary clutch pedal 11 and the clutch electric push rod 4 driving the secondary clutch pedal 11 do not affect each other, thereby having a wider range of applications.

[0028] Similarly, the brake push rod 12 is connected with an extension piece 13, and the extension piece 13 is in contact with the auxiliary brake pedal 15 through the second connecting piece 14. In the present embodiment, the brake push rod 12 is in a retracted state by default. When the brake push rod 12 is braking, the free end of the brake push rod 12 is extended, and the extension piece 13 at the end of the brake push rod 12 is extended together. Then, the extension piece 13 will push the second connecting piece 14 to move downward, thereby the second connecting piece 14 drives the auxiliary brake pedal 15 to move downward to achieve the braking purpose.

[0029] When the brake electric push rod 12 contracts, the extension piece 13 moves away from the second pin 17, and the auxiliary brake pedal 15 returns to the initial state due to its own resilience, and the brake is released.

[0030] Since the extension piece 13 and the second pin 17 are in floating connection, when the co-pilot has a trainer, manually stepping on the auxiliary brake pedal 15 and the brake electric push rod 12 driving the auxiliary brake pedal 15 do not affect each other, thereby having a wider range of applications.

[0031] The fixing bracket 1 is fixedly connected to the co-pilot seat slide rail 2, which can be achieved by welding or bolting. The specific method can be determined according to actual needs.

[0032] Because there is a large reaction force when the two electric push rods drive the clutch and the brake, the electric push rods can be firmly fixed by fixing the fixing bracket 1 on the co-pilot seat slide rail 2, so that the electric push rods can accurately execute instructions.

[0033] The pressure block 9 is rotatably connected to the secondary clutch connecting rod 6 via the first bearing 10. When the pressure block 9 is pressed downward, it will drive the secondary clutch connecting rod 6 to rotate together through the secondary clutch pedal 11. When the downward pressure of the pressure block 9 disappears and resets, the secondary clutch pedal 11 resets under the action of its own rebound force instead of being reset under the action of the pressure block 9. Therefore, when a force is applied to the secondary clutch pedal 11 alone, it will not affect the clutch electric push rod 4, and the two can be used independently of each other.

[0034] See also Figure 1 and Figure 3 The pressure block 9 includes a connecting rod 91 connected to the first connecting member 8 and two clamping plates 92, one of the clamping plates 92 is fixedly connected to the connecting rod 91, and the two clamping plates 92 are fixedly connected by bolts 93, and the two clamping plates 92 are symmetrically arranged about the auxiliary clutch pedal 11.

[0035] In this embodiment, a structure of a pressure block is specifically disclosed. In this embodiment, two clamping plates 92 are provided on the pressure block 9, and the two clamping plates 92 are connected to the auxiliary clutch pedal 11 through bolts 93;

[0036] This connection method is convenient for disassembly. When it is not needed, it can be separated from the auxiliary clutch pedal 11 by removing the bolts 93. Of course, other methods can also be used to press down the auxiliary clutch pedal 11: for example, a pressure plate is provided above the auxiliary clutch pedal 11, or the pressure block 9 is directly welded to the auxiliary clutch pedal 11. The specific method can be selected according to needs.

[0037] The first pin 5 is vertically arranged to the free end of the clutch electric push rod 4. At this time, the first pin 5 is horizontally arranged. When the clutch electric push rod 4 contracts, the first connecting member 8 can be driven to move backward by the first pin 5.

[0038] The second connecting member 14 is rotatably connected to the auxiliary brake link 7 via a second bearing 16 .

[0039] See also Figure 2 The second connecting member 14 includes a triangular plate 14 rotatably connected to the auxiliary brake connecting rod 7, and a second pin 17 is fixedly connected to one side of the triangular plate 14, and the second pin 17 cooperates with the extension member 13; the other side of the triangular plate 14 is connected to a pressure plate through a horizontal rod, and the pressure plate is located above the auxiliary brake pedal 15.

[0040] In this embodiment, when the free end of the brake electric push rod 12 is extended, it will drive the extended member 13 connected thereto to move forward, and the extended member 13 will drive the second pin 17 matched thereto to move, and the second pin 17 will drive the triangular plate 14 to rotate, thereby realizing the depression of the auxiliary brake pedal 15.

[0041] The end of the extension piece 13 away from the brake push rod 12 is provided with a recessed groove 131 , and the second pin 17 matches with the recessed groove 131 . The setting of the recessed groove 131 allows the second pin 17 to exactly match with the extension piece 13 .

[0042] The clutch electric push rod 4 and the brake electric push rod 12 are high-speed electric push rods, and encoders are arranged inside the clutch electric push rod 4 and the brake electric push rod 12, and the clutch electric push rod 4 and the brake electric push rod 12 and the encoders are electrically connected to a central processing unit.

[0043] When there is an obstacle or dangerous situation in front of the car, the driver fails to brake in time, the central processing unit detects the obstacle through the sensor, and sends instructions to control the clutch electric push rod 4 and the brake electric push rod 12 of the device, and the clutch electric push rod 4 and the brake electric push rod 12 drive the auxiliary clutch pedal 11 and the auxiliary brake pedal 15 to brake, so that the car stops smoothly; this device is the last safety barrier for driving trainees, which can actively drive the auxiliary clutch pedal 11 and the auxiliary brake pedal 15 in a very short time to ensure the safety of the trainees;

[0044] This device is installed in the co-pilot position and does not affect the normal driving of the main driver. It is independent of the manual pressing of the auxiliary brake pedal 15 and the auxiliary clutch pedal 11 and does not affect each other.

[0045] In addition, the central processing unit used in this embodiment can be a PLC controller, which can realize a processor with programming capabilities. There are many types of sensors currently on the market, which will not be described here; in addition, multiple sensors are provided, which are arranged on the surrounding body of the car, so that the surrounding area can be guaranteed to be safe; in addition, the sensor is also electrically connected to the central processing unit, and its connection method is the existing technology, which will not be described in detail here.

[0046] High-speed electric push rod is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. It has large push and pull force and fast speed; and has a self-locking function, which can increase the safety of the equipment. With a built-in potentiometer, the comprehensive positioning accuracy can reach 0.1mm; it can be used for a long time in harsh environments without maintenance, and is suitable for a variety of working conditions.

[0047] The clutch electric push rod 4 can achieve half clutch and full clutch by controlling its extension stroke and speed; the brake electric push rod 12 can achieve point braking, full braking, slow braking and other states by controlling its stroke and speed. When the central processing unit detects danger ahead through the sensor and needs to brake, it will send a command to the clutch electric push rod 4 to achieve full clutch, and then send a command to the brake electric push rod 12 to brake, so that the car will not stall, and it will slow down and stop relatively smoothly, which can fully simulate a skilled driver and bring comfort and safety to the trainees.

[0048] The working process of the present invention is as follows: the clutch electric push rod 4 is in an extended state by default. When the clutch electric push rod 4 is instructed to perform clutch, the free end of the clutch electric push rod 4 contracts, and the first pin 5 connected to the end of the clutch electric push rod 4 drives the first connecting member 8 to rotate (from Figure 1The direction shown is counterclockwise rotation), the first connecting member 8 drives the secondary clutch pedal 11 to press down through the pressing block 9, which is consistent with the action of a person's foot pressing down on the clutch pedal; when the free end of the clutch electric push rod 4 is instructed to retract, the first pin 5 connected to the clutch electric push rod 4 will lose its effect on the first connecting member 8, and the secondary clutch pedal 11 will return to the initial state under the action of its own rebound force, and the clutch is released;

[0049] Because the first pin 5 and the first connecting member 8 are in floating connection, when the co-pilot has a trainer, manually stepping on the secondary clutch pedal 11 and the clutch electric push rod 4 driving the secondary clutch pedal 11 do not affect each other, thereby having a wider range of applications.

[0050] Similarly, the brake push rod 12 is connected with an extension piece 13, and the extension piece 13 is in contact with the auxiliary brake pedal 15 through the second connecting piece 14. In the present embodiment, the brake push rod 12 is in a retracted state by default. When the brake push rod 12 is braking, the free end of the brake push rod 12 is extended, and the extension piece 13 at the end of the brake push rod 12 is extended together. Then, the extension piece 13 will push the second connecting piece 14 to move downward, thereby the second connecting piece 14 drives the auxiliary brake pedal 15 to move downward to achieve the braking purpose.

[0051] When the brake electric push rod 12 contracts, the extension piece 13 moves away from the second pin 17, and the auxiliary brake pedal 15 returns to the initial state due to its own resilience, and the brake is released.

[0052] Since the extension piece 13 and the second pin 17 are in floating connection, when the co-pilot has a trainer, manually stepping on the auxiliary brake pedal 15 and the brake electric push rod 12 driving the auxiliary brake pedal 15 do not affect each other, thereby having a wider range of applications.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
