Abstract
The invention discloses a kind of safe handbrake mechanisms, including ontology, push rod and button, tooth plate is provided on the ontology, one end of the push rod is connected with button, the other end of the push rod and one end end of pawl are inconsistent, and position is rotatably connected on the ontology among the pawl, and the other end of the pawl is matched with the tooth plate, a spring is provided between the button and the push rod, the elastic force of the spring is less than active force when parking between the pawl and tooth plate.After increasing spring, when parking, if touching button unintentionally, due to the active force when elastic force of spring is less than parking between pawl and tooth plate, button past can only inside contract, it not will push pawl abjection tooth plate, avoid unlock parking brake unintentionally and cause danger, in addition, after parking is over, button or push rod will not be damaged using push button energetically since the buffer function of spring exists.
Description
Technical field
The present invention relates to auto parts fields, more particularly, to a kind of safe hand brake device.
Background technique
Referring to a kind of automobile hand brake of patent of invention title that the applicant applies, Authorization Notice No.: CN203958118U, hand
Active force is directly applied to above pawl by the thumb-button push rod connection pawl of brake, and the power being applied on button is greater than parking active force
When can make pawl be directly detached from tooth plate cause unlocked state, this will result in danger.
In addition, it is desirable to when unlocking, needing slightly to lift parking brake could be unlocked, if when parking, the mistake of parking brake drawing
Tightly, then lifting upwards to be extremely not easy, then is difficult in the case where up lifting parking brake again, press unblock button by force, having can
It can damage manual brake button.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of safe hand brake device, avoids tensing situation in parking brake
It is unlocked caused by lower accidentally touching button.
In order to solve the above technical problems, the present invention is addressed by following technical proposals: a kind of safe handbrake mechanism, packet
Include ontology, push rod and button, tooth plate be provided on the ontology, one end of the push rod is connected with button, the push rod it is another
One end and one end end of pawl are inconsistent, and position is rotatably connected on the ontology among the pawl, the pawl it is another
One end is matched with the tooth plate, and a spring is provided between the button and the push rod, and the elastic force of the spring is less than
Active force when parking between the pawl and tooth plate.After increasing spring, when parking, if touch unintentionally by
Button, due to the active force when elastic force of spring is less than parking between pawl and tooth plate, button only can not will push spine toward inside contracting
Pawl deviates from tooth plate, avoids unlock parking brake unintentionally and causes danger, in addition, after being over when parking, i.e., using energetically by pressing
Button will not damage button or push rod since the buffer function of spring exists.
In above-mentioned technical proposal, specifically, the button includes button head and push-button socket, setting is free in the button head
Chamber, the spring are arranged in the cavity, and the push rod penetrates in the cavity after passing through the push-button socket, with the spring
It is in contact.
The beneficial effects of the present invention are: after increasing spring, when parking, if touching button unintentionally, due to
The active force when elastic force of spring is less than parking between pawl and tooth plate, button only can not will push pawl abjection toward inside contracting
Tooth plate avoids unlock parking brake unintentionally and causes danger, in addition, push button energetically is used after parking is over, due to
The buffer function of spring exists, and will not damage to button or push rod.
Detailed description of the invention
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the cooperation schematic diagram of button and push rod.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
Referring to Fig. 1-Fig. 2, a kind of safe handbrake mechanism, including ontology 1, push rod 2 and button 3 is provided with tooth plate on the ontology 1
4, one end of the push rod 2 is connected with button 3, and the other end of the push rod 2 and one end end of pawl 5 are inconsistent, the spine
The intermediate position of pawl 5 is rotatably connected on the ontology 1, and the other end of the pawl 5 is matched with the tooth plate 4, the button 3
A spring 7 is provided between the push rod 2, the elastic force of the spring 7 is less than when parking between the pawl 5 and tooth plate 4
Active force.
The button 3 includes button head 31 and push-button socket 32, is provided with cavity 33, the spring 7 in the button head 31
It is arranged in the cavity 33, the push rod 2 penetrates in the cavity 33 after passing through the push-button socket 32, with 7 phase of spring
Contact.
After increasing spring, when parking, if touching button unintentionally, when being less than parking due to the elastic force of spring
Active force between pawl and tooth plate, button only can not will push pawl abjection tooth plate, avoid and unlock unintentionally toward inside contracting
Parking brake causes danger, in addition, after parking is over, i.e., using push button energetically, since the buffer function of spring exists,
Button or push rod will not be damaged.
