Problems solved by technology

[0003] 1) When there is a special need to stop, it is easy to forget to pull the hand brake
[0004] 2) The parking place is usually on an uneven ground, either uphill or downhill, so the operator is prone to automatic walking after walking away, causing unnecessary damage accidents
[0005] 3) Novices can easily step on the wrong pedal, causing damage to life and structures
[0006] 4) It is difficult for freshmen to start uphill, and it is easy to stop and turn off the engine and retreat, which leads to a waste of time for failing the assessment
[0007] 5) It is easy to step on the accelerator and cause a speeding accident
[0008] 6) The hand brake system is complicated, not only the manufacturing cost is high, but also the maintenance parts are easily damaged
[0009] 7) The operation is complicated and heavy, and it is not portable
[0011] 9) The power consumption of the power supply is large

Embodiment 1

[0034] like Figure 1-2 Shown: an automatic brake master cylinder and a self-locking anti-theft safety device, including a brake master cylinder and an interlocking lock structure. The brake master cylinder includes an upper chamber and a lower chamber that are connected and parallel to each other. Connected to the oil storage device, one side of the upper chamber cooperates with the interlocking lock structure to realize switching between the connection and non-communication between the oil storage device and the lower chamber; the lower chamber is equipped with a piston rod 8 and a main piston 5, and the main piston is realized in the lower chamber. reciprocating motion.

[0035] One side of the lower cavity is detachably connected with a joint 20 communicating with the main brake pipeline, and the detachable connection mode is a bolt 19 connection.

[0036] The outer side of the lower cavity close to one end of the joint includes a step 21, and the step is fixed by bolts a...

Embodiment 2

[0042] The inner wall of the lower chamber is provided with a groove and an oil seal-11.

[0043] A plug 24 is installed on the end of the upper chamber close to the valve stem, and the matching part with the valve stem includes a reset chamber with a built-in spring 23. The inner wall of the upper chamber is grooved and an oil seal 22 is housed.

[0044] The top of the upper cavity communicates with the oil storage device through the pipe head 35 , and the oil storage device includes an oil storage rack 15 and an oil injection chamber 14 .

[0045] Working principle: When the key plate of the interlocking lock structure is opened, the valve stem moves to the right, the oil in the oil storage device flows into the circumferential oil groove, the pedal is stepped on many times to move the piston rod left and right, and the oil flows into each sub-cylinder to realize the braking effect. When parking, the key can only be taken out after the accelerator is closed. When the key is ...

Abstract

The invention discloses an automatic brake master cylinder and self-locking anti-theft safety device, and belongs to the field of engineering mechanical and electrical installation equipment. The device comprises a brake master cylinder and a linkage lock structure, the brake master pump comprises an upper cavity and a lower cavity which are communicated and parallel, the upper portion of the upper cavity is communicated with an oil storage device, and one side of the upper cavity is matched with the linkage lock structure to realize switching between communication and non-communication between the oil storage device and the lower cavity; and the lower cavity is matched with a main piston, and the main piston reciprocates in the lower cavity. When a key plate of the linkage lock structure is opened, a valve rod moves rightwards, oil in the oil storage device flows into a circumferential oil groove, the piston rod is moved leftwards and rightwards by treading the pedal for many times, and the oil flows into branch pumps to achieve the braking effect. During parking, when the key is taken out, the valve rod returns, the oil storage device and the lower cavity are not communicated, the pedal needs to be stepped down before the key is taken out, the key can be taken out under the braking condition, and the function not only plays an anti-theft role, but also plays a role in preventing an automobile body from sliding away.

Description

technical field [0001] The invention belongs to the field of engineering electromechanical installation equipment, and in particular relates to an automatic brake master cylinder and a self-locking anti-theft safety device. Background technique [0002] At present, the existing engineering construction mechanical and electrical installation equipment, transportation equipment, agricultural machinery equipment, mining machinery equipment, air transportation equipment, etc. Especially on zero-hour parking problem, common measure often adopts the way of pulling on handbrake after parking to solve parking problem, and there is at least one or more of following problems in this method. [0003] 1) It is easy to forget to pull the hand brake when there is a special need to stop. [0004] 2) The parking place is usually on an uneven ground, either uphill or downhill, so the operator is prone to automatic walking after walking away, causing unnecessary damage accidents. [0005] 3...
