Description
Technical Field
The invention relates to the technical field of electric automobile parts, in particular to a variable-volume vacuum tank.
Background
In recent years, electric vehicles have been developed vigorously, research and development efforts and investments of various large host factories and research and development organizations have been increased, many new technologies and new structures are emerging continuously, and the technologies of electric vehicles and parts are changing day by day.
At present, a brake boosting system of an electric automobile mainly provides boosting for a vacuum booster through vacuum pumping of a vacuum pump and a vacuum tank, when emergency continuous braking is met, the problem that the vacuum degree of the vacuum system is insufficient possibly occurs, pedal force is increased, and braking force is insufficient, and the variable-volume vacuum tank is invented for solving the problems.
Disclosure of Invention
The invention aims to solve the technical problem of providing a variable-volume vacuum tank, wherein the middle part of the vacuum tank is provided with an elastic rubber structure, the volume of the tank body can be changed along with the change of the vacuum degree in the tank, and meanwhile, a spring and a limiting sleeve are assembled inside the vacuum tank to adjust the vacuum degree of a vacuum system.
The technical problem solved by the invention is realized by adopting the following technical scheme: a variable-volume vacuum tank comprises a tank body, a spring and a limiting sleeve, wherein the middle part of the tank body is provided with a telescopic rubber elastic structure, the limiting sleeve is arranged in the tank body, and the bottom end of the limiting sleeve is fixed at the bottom of the tank body; when the tank body is in the maximum state, one end of the spring is tightly propped against the bottom of the tank body, and the other end of the spring extends out of the limiting sleeve to be tightly propped against the top of the tank body; when the tank body is compressed, the spring is arranged in the limiting sleeve after being compressed, the top end of the limiting sleeve is attached to the top of the tank body, and two ends of the spring tightly support the top and the bottom of the tank body respectively.
Furthermore, the top of the tank body is provided with an exhaust port.
Further, a sensor is arranged at the top of the tank body.
Further, the limiting sleeve is welded and fixed at the bottom of the tank body.
Furthermore, the stop collar is cylindrical.
Further, the spring is a coil spring.
The invention has the advantages that:
the vacuum tank has a simple structure, and when the vacuum degree in the vacuum tank body is lower than a set value, the elasticity of the spring pushes the upper surface and the lower surface of the tank body, so that the volume of the vacuum tank is increased, and the vacuum degree is increased; the limiting sleeve in the vacuum tank body prevents the spring from being compressed too much, so that the volume of the vacuum tank is greatly reduced; the problem of the braking force is not enough when electric automobile promptly continuous braking is solved.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic top view of the present invention;
FIG. 3 is a schematic view of the invention in a compressed state;
FIG. 4 is a schematic view of the invention in an expanded state;
in the figure: 1-tank body, 2-rubber elastic structure, 3-spring, 4-spacing sleeve, 5-exhaust port and 6-sensor.
Detailed Description
The following describes the specific embodiments of the present invention with reference to examples, so that the technical solutions and the advantages thereof are more clear and clear. The following described embodiments are exemplary and are intended to be illustrative of the invention, but are not to be construed as limiting the invention.
Example (b):
as shown in fig. 1-4, the invention specifically discloses a variable-volume vacuum tank, which comprises a tank body 1, a spring 3 and a limit sleeve 4, wherein the top of the tank body 1 is provided with an exhaust port 5, and the top of the tank body 1 is provided with a sensor 6.
The middle part of the tank body 1 is provided with a telescopic rubber elastic structure 2, the limiting sleeve 4 is arranged inside the tank body 1, the limiting sleeve 4 is cylindrical, and the bottom end of the limiting sleeve 4 is welded and fixed at the bottom of the tank body 1; the spring 3 is a spiral spring, and the free height of the spring 3 is greater than that of the limiting sleeve 4.
When the tank body 1 is in a maximum state, one end of the spring 3 is tightly propped against the bottom of the tank body 1, and the other end of the spring extends out of the limiting sleeve 4 to be tightly propped against the top of the tank body 1; when the tank body 1 is compressed, the spring 3 is compressed and then placed in the limiting sleeve 4, the top end of the limiting sleeve 4 is attached to the top of the tank body 1, and two ends of the spring 3 tightly support the top and the bottom of the tank body 1 respectively.
When the vacuum tank does not work and is in a free state, the vacuum tank is jacked to be in a longest state by the spring 3, but when the vacuum tank is vacuumized, the tank body 1 tends to be compressed due to the rubber elastic structure 2, and the limiting sleeve 4 can prevent the tank body 1 from being compressed at the moment, so that the volume cannot be excessively reduced; when the brake is continuously performed and the vacuum degree in the tank is rapidly reduced, the spring 3 can prop against the top and the bottom of the tank body 1 to rapidly increase the volume of the tank body, so that the vacuum degree is increased, and the braking force of the electric automobile is not influenced.
The invention has the beneficial effects that:
the vacuum tank has a simple structure, and when the vacuum degree in the vacuum tank body is lower than a set value, the elasticity of the spring pushes the upper surface and the lower surface of the tank body, so that the volume of the vacuum tank is increased, and the vacuum degree is increased; the limiting sleeve in the vacuum tank body prevents the spring from being compressed too much, and the volume of the vacuum tank is greatly reduced; the problem of the braking force is not enough when electric automobile promptly continuous braking is solved.
The above disclosure is only one preferred embodiment of the present invention, and certainly should not be construed as limiting the scope of the invention, which is defined by the claims and their equivalents.
