Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 8, a hand brake control device for preventing an automobile from slipping, wherein a hand brake 5 is arranged on a base 1, the device comprises a main controller, the main controller is electrically connected with a state detection mechanism and a driving circuit, the state detection mechanism comprises a first detection unit for detecting whether a driver is on position, the driving circuit is electrically connected with a linear output device, the linear output device is fixedly arranged on the base 1, and an output end of the linear output device faces upwards to the hand brake 5.

When the automobile brake device is used, the state detection mechanism continuously detects a driver, the main controller obtains the in-place state of the driver through the first detection unit, when the driver leaves the automobile, the first detection unit cannot continuously detect the driver, the main controller drives the linear output device to act through the driving circuit at the moment, and the linear output device is utilized to push the hand brake 5 upwards, so that the hand brake 5 is ensured to lock the automobile when the driver leaves, and the phenomenon of sliding is avoided; when the driver returns to the automobile, the first detection unit detects the driver, and the main controller drives the linear output device to act through the driving circuit, so that the linear output device is separated from the hand brake 5, and the driver can drive the automobile normally. It is considered that the operation of the linear output device is not affected even if the driver has pulled up the handbrake 5 when leaving the automobile, and therefore the position of the handbrake 5 does not need to be detected when the driver leaves the automobile, thereby reducing the complexity of the control process.

Adopt the utility model discloses, can forget when pulling up manual brake 5 at the driver and lift up manual brake 5 automatically to lock the car and die, avoid appearing the swift current car phenomenon.

The present invention relates to a linear output device, and more particularly to a linear output device for outputting linear power, such as a cylinder, a hydraulic cylinder, a ball screw mechanism, or a linear motor. Considering the limited space on the base 1, it is preferable to provide the linear output device as the electric push rod 2, the push rod 3 of the electric push rod 2 faces upward to the movable end of the handbrake 5, and the support part 4 is fixedly connected to the push rod 3. Electric putter 2's volume is less, and need not extra auxiliary device, the installation of being convenient for, and supporting part 4 is used for supporting manual brake 5, makes electric putter 2 act on the power distribution on manual brake 5 even, avoids electric putter 2 or manual brake 5 impaired.

Specifically, the supporting part 4 comprises an arc-shaped supporting plate 7 fixedly connected with the push rod 3, the supporting plate 7 faces the hand brake 5, and a gasket 8 is fixedly arranged on the inner side of the supporting plate 7. The open-ended width of layer board 7 is greater than the diameter of manual brake 5 to make layer board 7 can hold up manual brake 5 smoothly, avoid manual brake 5 lateral deviation to appear, because again need take place relative movement with layer board 7 at the in-process manual brake 5 that holds up manual brake 5, so set up liner 8, avoid layer board 7 and manual brake 5 to take place the scraping and lead to the wearing and tearing of manual brake 5.

The specific connection mode of the supporting plate 7 and the push rod 3 is as follows: the dorsal part fixedly connected with sleeve 6 of layer board 7, sleeve 6 cover is established on catch bar 3, and sleeve 6 passes through bolt 9 and catch bar 3 fixed connection. For the convenience of use, the electric push rod 2 is provided with a through hole in advance at the extending end of the push rod 3, so that the sleeve 6 and the push rod 3 can be conveniently connected together by penetrating the through hole through the bolt 9, and the mounting of the supporting plate 7 is completed.

Considering that the linear output device may have a fault after long-term use, for example, the linear output device cannot be successfully reset, and the manual brake 5 is blocked, the state detection mechanism further comprises a second detection unit for detecting the position of the push rod 3, and the main controller is electrically connected with a fault alarm. After the driver gets back to the automobile, if the second detection unit detects that the linear output device cannot be reset smoothly and possibly interferes with the operation of putting down the hand brake 5 by the driver, the main controller sends out a fault alarm to the driver through the fault alarm to remind the driver to remove the fault in time and guarantee that the automobile can be driven smoothly.

In order to ensure the warning effect, the fault warning device comprises a loudspeaker and a light source, and a dual mode of sound warning and light warning is adopted, so that the situation that the driver ignores the warning signal can be effectively avoided.

After the driver gets rid of the trouble, if the trouble alarm fails to in time to close, then can produce the interference to driver's driving process, therefore main control unit electric connection has the warning annihilator, makes the driver can close the trouble alarm through warning annihilator is manual after the trouble-shooting, and in this embodiment, the warning annihilator includes a elimination button, and the driver can close the trouble alarm through pressing the elimination button, and is simple swift.

In order to accurately detect the on-position state of the driver and the reset state of the linear output device, the state detection mechanism may adopt various detection methods, for example, the driver and the linear output device are photographed by a camera, and then the picture is analyzed to obtain the on-position state and the reset state, or the position of the driver and the linear output device is detected by a distance sensor. In consideration of the actual cost and the load of the main controller, the first detection unit is set as an obstacle avoidance sensor, specifically, an infrared distance sensor or an ultrasonic distance sensor, and in this embodiment, the state detection mechanism is set as an infrared distance sensor; the second detection unit is provided as a failure detection circuit.

Finally, the device also comprises a power supply module, wherein the input end of the power supply module is connected with a vehicle-mounted 12V power supply.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
