For vehicle, especially for electric automobile, weight and course continuation mileage are negative correlation；These traditional vacuum tanks also use plastic-spraying
Technique, but tank interior because reasons in structure be difficult carry out coating processing, so antiseptic effect is also poor.In addition, these are traditional
Vacuum tank, because of processing technology reason, two end caps are all to make to be then welded into together respectively, are all simple cavity inside it
Structure, tank intensity is general.Therefore, the size of vacuum tank quality, can produce influence, its antiseptic property to the course continuation mileage of vehicle
It is good no, influence the normal work of vehicle brakes.
The content of the invention
The purpose of this utility model is, in order to solve traditional vacuum tank quality weight, the course continuation mileage of vehicle to be produced negative
Face rings；Tank interior is unable to plastic-spraying processing because of reasons in structure, and two ends tank body is welded to connect using metal, and antiseptic effect is poor；Tank
There is provided a kind of lightweight high-intensity vacuum used for electric vehicle of reasonable in design for the problems such as internal cavity, tank intensity are not enough
Tank.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of electric automobile
Lightweight high-intensity vacuum tank, including tank body, several joints being arranged on tank body, check valve and vacuum sensing
Device, it is characterized in that several described joints and tank body are the integral structures using polyamide 66 disposal molding, in tank body
Wall is provided with some symmetrical reinforcements of tank body center line.The vacuum tank manufactured for sheet metal, such as Q235, its is close
Spend for 7.85g/cm3, for the vacuum tank that volume is 2L, weight is about 1.1kg, for electric automobile, weight and continuation of the journey
Mileage negative correlation influence is very big.The technical program uses polyamide 66, i.e. PA66 or nylon66 fiber, and it has impact resistance and high-strength
Degree feature, and machinability, chemical resistance are good, density is only 1.1g/cm3, and for the vacuum tank that volume is 2L, weight is only about
0.7kg.The external boss of this structure design, it is to avoid traditional tank body is relatively thin because of wall thickness, it is impossible to be directly threaded the defect of auxiliary section.
And polyamide 66 material is a kind of natural anticorrosion material, is not required to specially treated.This product is molded using Shooting Technique, two end cap
Connection is also not required to use Metal Material Welding, and tank interior is strengthened whole tank body by the reinforcement of various structures.
Preferably, several described joint areas are provided with boss, the thickness of boss is more than the wall thickness of tank body.Boss with
Tank skin by arc transition, is set according to different jointing requirements to the screw that different size is carried out in boss.
Preferably, described reinforcement is trapezoidal platy structure, wherein trapezoidal waist and the inwall in length of tank direction
Connect as one.Increase tank structure intensity, reinforcement and tank skin can disposal moldings.
Preferably, described reinforcement is circular ring structure, the inner round wall that one end and the tank body of circular rings have connects
It is connected in one.For tank body two ends and end cap the reinforcement of circular ring structure can be used with straight barrel connecting portion.
Preferably, described reinforcement is trapezoidal platy structure, trapezoidal big base is connected with the inwall of tank body one end
It is integrated.
Preferably, being provided with screw in described boss.
Preferably, described tank body is cylinder, tank body two ends inwall is provided with reinforcement, and described reinforcement is in well word
Trellis.
Preferably, described tank body is formed by two and half tank bodies are axially connecting, some in two and half tank bodies
Reinforcement is mutually in staggered distribution.It is segmented according to Shooting Technique requirement, then carries out plastic welding connection.
The beneficial effects of the utility model are：Because each joint boss, each reinforcement use polyamide 66 Shooting Technique, and
Tank body is integrally formed formula structure, it is not necessary to separately fabricated, fixed, welding etc. is carried out to each part, modular construction is reduced, simplified
Production process, improves antiseptic property, reduces cost of manufacture；The intensity between part and tank body is added, is greatly reduced
The weight of product；Tank interior devises the reinforcement of multiple structural forms, it is ensured that product overall construction intensity, adds continuous
Navigate mileage.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of lightweight high-intensity vacuum tank of the present embodiment, as shown in Figure 1 and Figure 2, including cylindrical tank 1, on tank body 1
Provided with three joints of boss 2, and check valve and vacuum sensor.Three joints of boss 2 and tank body 1 are to use polyamide 66
Material is by the integral structure of once injection moulding, and the inwall of tank body 1 is provided with symmetrical a variety of many of the center line of tank body 1
Part reinforcement 3.
The effect of each primary clustering is described below in this example：Vacuum tank is used for storing vacuum, is used for vacuum booster；Very
Reciprocal of duty cycle sensor is collection vacuum degree, and signal is provided for control strategy；Check valve controls vacuum conducting direction；Boss joint is used
To connect each associated component.
Specifically, the thickness of three joint areas of boss 2 is 5 times of the wall thickness of tank body 1, the portion connected according to boss 2
Part sets the connecting screw hole of different size in the centre of boss 2.
The present embodiment reinforcement 3 has three kinds of structure types：One is the trapezoidal hardened structure of reinforcement 3, and 8 are set altogether, wherein ladder
The inwall of the waist of shape and the length direction of tank body 1 is connected as one, and the end cap position inwall on trapezoidal big base and the one end of tank body 1 connects
It is connected in one.Because Shooting Technique needs, tank body 1 is formed by two and half tank bodies are axially connecting, therefore, each in each half tank body
If 4 reinforcements 3 in 4 reinforcements 3, two and half tank bodies are mutually in staggered distribution, that is, it is spaced apart, makes in two and half tank bodies
Reinforcement 3 is located at different linear positions respectively.Two be that reinforcement 3 is circular ring structure, and one end and the tank body 1 of circular rings are had
Some inner round wall are connected as one, i.e., in the straight tube of tank body 1 and end cap connecting portion, the edge at end cap position and straight tube inwall
Circular rings reinforcement can be made.Three be checked spun antung shape reinforcement, is mainly used in the two ends end cap inwall position of tank body 1.
It, to explanation of the present utility model, is limited of the present utility model that above-described embodiment, which is, any new to this practicality
Structure after the simple transformation of type etc. belongs to protection domain of the present utility model.
