The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein "and/or" packet
Include any and all combinations of one or more related listed items.
As shown in Figure 1, a kind of explosion-proof vent valve, including guiding axis 10, spring 20, main body 30, the first sealing ring 40, fixation
Seat 50, film paper 60, upper cover 70, offer through-hole 31 in the middle part of the main body 30, several air holes are offered around through-hole 31
32, first sealing ring 40 is fixedly installed in one end of the main body 30, and one end of the fixing seat 50 is installed on described
On one sealing ring 40, the other end is fixedly installed in upper cover 70, the film paper 60 be placed in the fixing seat 50 and upper cover 70 it
Between, there is mounting portion 51, one end of the guiding axis 10 passes through through-hole 31 and is fixedly installed in the installation in the fixing seat 50
In portion 51, the spring 20 is sheathed on one end of the guiding axis 10 and offsets respectively with the other end of guiding axis 10 and main body 30
It holds, the guiding axis 10 is hollow structure with mounting portion 51, offers several apertures 71 in the upper cover 70.
When air pressure inside battery pack is less than blow-up point, air pressure pass sequentially through guiding axis 10, the through-hole 31 in main body 30,
Mounting portion 51, film paper 60, the aperture 71 in upper cover 70 carry out the pressure inside and outside regulation valve body, make the inside and outside pressure balance of valve body.
When the pressure in battery pack increases suddenly, when air pressure is greater than blow-up point in battery pack, air pressure pushes guiding axis 10
Mobile to the direction of fixing seat 50, spring 20 is compacted, and the fixing seat 50 drives the upper cover 70 to the side far from main body 30
To movement, so that fixing seat 50 and main body 30 is generated gap, air pressure is discharged along gap, achievees the purpose that quick pressure releasing, meanwhile,
Spring 20 generates deformation in the case where guiding axis 10 and main body 30 squeeze jointly, and after the completion of pressure release, spring 20 returns to the original form,
Entire valve body components are made to be restored to original position.
In this way, explosion-proof vent valve, through being equipped with for guiding axis 10, spring 20 and fixing seat 50, inside battery pack
Air pressure be less than blow-up point when, by film paper 60 come the pressure inside and outside regulation valve body, product plays the role of waterproof and breathable；Work as electricity
Pressure in the packet of pond when increasing suddenly, and when air pressure is greater than blow-up point in battery pack, gas push guiding axis 10 is to 50 side of fixing seat
To movement, spring 20 is compacted, and fixing seat 50 is separated with main body 30, achievees the purpose that rapid pressure release, and protection battery pack will not be by
Damage, after the completion of pressure release, spring 20 is restored to original form, makes each member reset；It can be recycled again, save cost,
Meanwhile explosion-proof ventilation valve structure is simple, it is easy for installation.
Further, in order to make the more firm of entire explosion-proof vent valve installation, the explosion-proof vent valve further includes second
Sealing ring 80 offers annular groove 33 on 30 outer layer of main body, and second sealing ring 80 is sheathed on the annular groove
On 33.
In this way, entire explosion-proof vent valve is installed on firmly in battery pack by the second sealing ring 80, it will not be easily
It falls off, and the second sealing ring 80 can be reused, posts and saved resource again and make the firm of explosion-proof vent valve installation, at one stroke two
?.
Further, more firm in order to install fixing seat 50 and guiding axis 10, it does not fall off easily, the mounting portion
51 with the guiding axis 10 be threadedly coupled.
In this way, there is external screw thread in the outside of mounting portion 51, there is internal screw thread in the inside of guiding axis 10, makes inside and outside spiral shell by rotation
Line links closely, and is installed on guiding axis 10 firmly in fixing seat 50, will not fall off easily, ensure that explosion-proof vent valve will not damage easily
It is bad, it can use for a long time.
Further, in order to make film paper 60 not fall off easily, the fixing seat 50 is that interference is connect with the upper cover 70.
In this way, fixing seat 50 is firmly connected together with upper cover 70, not falling off easily accommodates film paper 60 for a long time
Between fixing seat 50 and upper cover 70, the normal work of explosion-proof vent valve ensure that.
Further, more firm in order to install the first sealing ring 40, first sealing ring 40 and the main body
30 connect for interference.
In this way, the first sealing ring 40 is connected in main body 30, facilitates fixing seat 50 and be mounted in main body 30, while existing again
When pressure increases, make fixing seat 50 and 30 quick separating of main body, and the first sealing ring 40 will not be detached from main body 30, ensure that anti-
Quick-fried vent valve works normally.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
