Description

Vehicle mechanical hand brake control device

Technical Field

The invention belongs to the technical field of vehicles, in particular to the technical field of parking brake control.

Prior Art

The parking brake is realized by pulling up or putting down a manual control rod of the parking brake controller by a driver, so the parking brake is commonly called as a hand brake, and the parking brake controller is commonly called as a hand brake. With the development of electronic technology, some vehicles with higher automation degree gradually replace a manually controlled parking brake controller with an intelligent electronic hand brake or automatic parking automatic control device. Therefore, the hand brake is divided into a mechanical hand brake depending on manual control of a driver and an electronic hand brake or automatic parking which does not depend on manual control of the driver completely according to different parking brake control modes.

The manual control mechanical hand brake controller is a group of mechanical lever devices capable of amplifying the force of the hands of a driver, is generally arranged beside a driver seat, and can control a parking brake friction execution assembly attached to a wheel or a transmission shaft to execute parking action by pulling up a hand brake pull rod by the driver when the driver needs to park for a long time. The hand brake controller is connected with the parking brake friction assembly device through a brake cable, and when a driver needs to park for a long time, force acting on the pull rod when the driver pulls up the hand brake pull rod is amplified through a lever and then is directly transmitted to the parking brake execution assembly through the brake cable, so that the parking brake execution assembly can be driven to generate enough brake force to achieve a parking brake target. When the hand brake pull rod is put down when the automobile needs to be driven, the brake state is relieved, and the automobile is in a normal driving state. The mechanical foot brake is also one of mechanical hand brakes, the structures of the foot brake and the common mechanical hand brake are basically consistent, and a steel wire pull wire is also adopted, so that only the control terminal is changed from a hand brake handle to a foot brake pedal, and the control terminal is usually arranged at the left foot. The large-scale vehicle needs a large parking braking force, the force of a driver pulling the hand brake pull rod through the hand brake pull rod is difficult to meet the torque required by the vehicle parking braking, and at the moment, high-pressure gas is usually adopted as a gas-cut-off braking device for amplifying the torque of the hand brake pull rod to be used as a parking braking executing component. At the moment, the hand brake pull rod is used as a high-pressure gas control switch of the air-break brake parking brake device to control the parking brake to execute the parking brake action, which is equivalent to that the high-pressure gas secondarily amplifies the moment of the driver pulling the hand brake pull rod so as to realize the parking brake of the large-sized vehicle. In order to ensure safety, the air brake parking brake of the large-sized vehicle is designed into a parking brake mode in which a parking brake friction plate is pressed by a strong spring to be tightly attached to a wheel hub friction part to generate a parking brake force as a normal brake parking state. When the vehicle is going, a driver releases the hand brake to control compressed air in the high-pressure air storage cylinder to enter the strong spring brake, so that the strong spring is released from pressing the parking friction plate, and the parking brake is released; when the automobile needs to be parked, a driver pushes the hand brake control rod to the parking position, compressed air in the strong spring brake is discharged, and the spring of the strong spring parking brake is popped out to press the parking brake friction plate to tightly press the hub, so that the automobile can be reliably stopped. The hand brake controller connected by a stay wire or the hand brake controller of a large vehicle connected by a high-pressure gas pipeline has the common points that the parking control does not need to depend on auxiliary control of vehicle state sensors such as acoustoelectric and photoelectric sensors, and the parking brake control of the vehicle is realized by manually operating a manual control rod of the hand brake controller by a driver, so that the hand brake controller has a common defect that the hidden trouble of vehicle sliding caused by forgetting to pull the hand brake exists for the driver.

In order to solve the problem that a mechanical hand brake has a sliding accident caused by forgetting to pull the hand brake, parking control devices such as an electronic hand brake and an automatic parking device are developed afterwards. The parking brake system is characterized in that various acoustic-optical-electric sensors are used for automatically detecting the running state of a vehicle, when the sensors detect that the vehicle needs to be parked, control signals which are in accordance with the preset condition for triggering the parking brake state are sent, a power control brake system such as a vehicle motor is started to complete the brake process, the parking brake mainly depends on an electronic control system of the vehicle, and the manual control of a driver is not completely relied on, so that the problem that a manual control parking brake device slips due to the fact that the driver forgets to pull a hand brake is solved. However, the electronic hand brake and the automatic parking device have the disadvantages of complex structure and high manufacturing cost, so that the electronic hand brake and the automatic parking device cannot completely replace a manually controlled mechanical hand brake at present.

The manual control mechanical hand brake is improved, and the situation that the manual control mechanical hand brake has the problem that a driver forgets to pull the hand brake to cause a sliding accident is necessary.

Thus, a feature defined as "first", "second", may explicitly or implicitly include one or more of the described features. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 and 2 are schematic structural diagrams of an embodiment of a manual mechanical hand brake device which is used as a driver seat and is also used as a driver seat according to the invention. The mechanical hand brake control end of the vehicle parking brake device is composed of a driver seat bearing seat plate 14 capable of being lifted upwards by a certain angle around a shaft 15, a brake cable pull rod 11, a brake cable 12, a seat bearing seat plate tension spring 13, other necessary structural components which are not shown in the figure and the like. Of course, the vehicle does not exclude the simultaneous arrangement of the traditional hand brake controllers as required, and the simultaneous arrangement can achieve better synergy. The seat load-bearing bottom plate 14 is fixedly connected with the brake cable pull rod 11, and the seat load-bearing bottom plate 14 and the brake cable pull rod 11 should be regarded as an integral part in the hand brake controller because the hand brake controller constitutes a hand brake control rod of the hand brake controller. When the seat bearing seat plate 14 is not acted by external force, namely a driver does not sit on the seat, the seat bearing seat plate 14 is at a position which is lifted upwards by a certain angle under the tension action of the tension spring 13, the brake wire pull rod 11 is driven to tension the brake wire 12 to control the parking brake assembly at the wheel part to be in a parking state (see figure 1), and at the moment, the seat bearing seat plate 14 plays the role of a hand brake pull rod in a traditional brake system in a vehicle; when the seat bearing seat plate 14 is pressed downwards by the buttocks or hands of a driver, namely the driver sits on the seat bearing seat plate 14 of the driver, the bearing seat plate 14 rotates downwards around the shaft 15 and presses on the seat bearing structure support 16 to drive the brake cable pull rod 11 to displace towards the right, the tension of the brake cable 12 is relieved, the parking state of the parking brake assembly controlled by the brake cable 12 is relieved, and the vehicle is in a driving state.

The vehicle provided with the hand brake control device in the embodiment is driven, when a driver gets off and leaves a driver seat, the tension spring can bounce the seat bearing seat plate 14, the parking device is in a braking state, when the driver gets on and sits on the seat, a hip part is bound to press down the seat bearing seat plate 14 in the bouncing state, at the moment, the driver completes the action of pressing down the hand brake control rod 14 by the hip part, the vehicle is in a driving state after the parking brake is released, and therefore the effect that the vehicle slipping accident caused by the fact that the driver forgets to pull the hand brake can be avoided by using the mechanical hand brake which does not depend on any sound, light, electricity and other detection sensors is achieved.

Fig. 1 and 2 show an embodiment of a seat bearing seat plate and seat structural member connecting shaft 15 at the rear edge of a seat bearing seat plate 14, in practice, the connecting shaft may be disposed at the front edge of the seat bearing seat plate or at other positions, as long as it can be realized that when no external force is applied, the seat bearing seat plate connected with a brake cable can be lifted up at one side under the action of a tension spring to drive a brake control device to perform a braking action. The tension of the tension spring 13 can be optimized according to the vehicle type, and the proper tension setting can prevent a child with small weight from being seated on the driver seat to release the braking state. The brake control components such as the tension spring 13, the brake cable pull rod 11, the brake cable 12 and the like on the seat in fig. 1 and 2 are also only schematic diagrams, and in practice, various structures suitable for being matched with the seat part can be adopted according to practical reasonable optimization design.

The mechanical hand brake device can be independently arranged and applied to a vehicle for controlling parking brake, and can also be matched with the original traditional hand brake control device for use. When the hand brake is used in a matched mode, the parking brake is additionally provided with the brake control end on the basis of the original traditional hand brake control, and the problem that the traditional mechanical hand brake slips due to the fact that the hand brake is forgotten to be pulled can be avoided. The specific matching design can have different optimized design schemes according to the specific conditions of the vehicle type.

It should be noted that the above-mentioned hand brake controller is a generic name, and does not refer to the hand brake pull rod that needs to be controlled by hand, but refers to a general brake mode that needs to be controlled by the driver to control the hand brake controller to control the parking brake.

Compared with the prior art, the invention has the characteristics of simple technology, small change to the vehicle, low cost and wide application range, and is suitable for various vehicles needing to be equipped with parking brakes.
