Description

Technical Field

[0001] The utility model discloses a multi-stage spring linear motion simulation system, belonging to the technical field of spring energy storage. Background Art

[0002] In the prior art, the planar multi-stage spring energy storage device stores energy by compressing a single-stage spring, and has the advantages of simple structure, long service life, and no pollution to the environment.

[0003] However, due to the limitation of elastic materials, the energy storage density is low. Now, the cross-sectional area of ​​the spring is generally increased to increase the spring strength and the number of coils and length of the spring to improve the energy storage density. However, increasing the cross-sectional area of ​​the spring material will increase the spring strength but reduce the elasticity, and it is easy to fatigue and break. Increasing the stiffness of the spring will also cause poor adaptability. Although increasing the number of coils of the plane spring can increase energy storage, it will increase torque and reduce efficiency.

[0004] In addition, the springs in the prior art are independent, have limited energy transmission capabilities, and cannot meet the needs of different occasions. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a multi-stage spring linear motion simulation system to solve the problem.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a multi-stage spring linear motion simulation system, including a slide rail, a plurality of sliders, and a plurality of springs; the sliders are slidably installed on the slide rail, and a mounting frame is fixed between every two sliders; the plurality of springs are all in the same plane; the springs are detachably installed between the two mounting frames.

[0007] Preferably, there are two slide rails, which are arranged in parallel.

[0008] Preferably, the mounting frame is hollow so that the spring can pass through the mounting frame.

[0009] Preferably, the first and second ends of the spring are respectively fixed to the mounting frame via a mounting seat; the mounting seat is mounted on the mounting frame via bolt threads; the first and second ends of the spring are mounted on the mounting seat via bolt threads.

[0010] Preferably, a pressure sensor is provided between the mounting seat and the spring, and the spring acts on the pressure sensor to detect the pressure applied to the spring.

[0011] Preferably, a laser distance measuring sensor is provided on the mounting frame, and the laser distance measuring sensor is used to measure the distance between adjacent mounting frames.

[0012] Preferably, a placement groove is provided on the top of the mounting frame; a mass block is placed on the placement groove.

[0013] Preferably, a damping member is installed between the two mounting frames.

[0014] Preferably, several springs are located on the same axial line.

[0015] Preferably, the axis lines of the plurality of springs are staggered.

[0016] Beneficial Effects

[0017] The utility model can be disassembled between the spring and the mounting seat, and between the mounting seat and the mounting frame, and has high operability, so as to be applied to linear motion simulations of different specifications. At the same time, damping parts and mass blocks are provided to simulate environmental variables that may exist in linear motion under different environments. Through the variable spring installation method, the equivalence of the spring can be studied, which provides a certain basis for the application of practical engineering (such as automobile braking, shock absorbing structure, and simulation of linear motion systems).

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Example 1

[0027] See also Figure 1-Figure 4 , a technical solution of a multi-stage spring 4 linear motion simulation system: including 2 slide rails 1, 8 sliders 2, and 6 springs 4.

[0028] Two slide rails 1 are arranged in parallel, and the slider 2 is slidably installed on the slide rails 1, so that the slider 2 can only perform linear motion; in one embodiment, the slide rail 1 adopts the existing ball slide rail, which has high precision, high speed and high rigidity performance.

[0029] Four sliders 2 are respectively installed on the two slide rails 1; the sliders 2 on the two slide rails 1 intersect through a mounting frame 3, and the mounting frame 3 is further fixed to the sliders 2, and the mounting frame 3 and the slide rails 1 are perpendicular to each other; in this way, four parallel mounting frames 3 are formed between the eight sliders 2.

[0030] The spring 4 is installed between the two mounting frames 3. Since the mounting frames 3 are hollow, the spring 4 can pass through the mounting frames 3. In this way, the spring 4 is not limited to being installed on two adjacent mounting frames 3, but can pass through the mounting frame 3 to connect with another mounting frame 3 (see Figure 4 ).

[0031] In order to realize the detachable installation of the spring 4 on the mounting frame 3, the head and tail ends of the spring 4 are respectively fixed to the mounting frame 3 through a mounting seat 40, and the head and tail ends of the spring 4 are threadedly mounted on the mounting seat 40 through bolts (not shown in the figure). In this way, the spring 4 can be removed from the mounting seat 40 by unscrewing the bolts, and the spring 4 can be replaced in this way, which has high operability and can be applied to linear motion simulations of different specifications.

[0032] In order to realize that the mounting seat 40 is detachably mounted on the mounting frame 3, the mounting seat 40 is threadedly mounted on the mounting frame 3 by bolts (not shown in the figure). Further, the mounting frame 3 is provided with a plurality of holes 32 for mounting the bolts of the mounting seat 40, preferably, the holes 32 are provided in a plurality and arranged regularly; wherein the holes 32 on the four mounting frames 3 correspond to each other one by one, so that the installed spring 4 is parallel to the movement direction of the slider 2; at the same time, the establishment of a plurality of holes 32 can make the mounting seat 40 have a wider installation range, thereby providing more variables for motion simulation.

[0033] In order to detect the pressure on the spring 4, a pressure sensor 8 is provided between the mounting seat 40 and the spring 4. The spring 4 acts on the pressure sensor 8 to generate a pressure value, and the pressure value is counted by the user.

[0034] In order to detect the movement distance of the mounting frame 3, a laser distance sensor 7 is provided on the mounting frame 3. The laser distance sensor 7 is used to measure the distance between adjacent mounting frames 3. The user calculates the movement distance of the mounting frame 3 based on the distance variable detected by the laser distance sensor 7.

[0035] In order to be applicable to simulated linear motion under different mass environments, a placement slot 31 is provided on the top of the mounting frame 3; a mass block 6 is placed on the placement slot 31, and the gravity of the mass block 6 acts on the mounting frame 3. By adjusting the gravity applied by the mass block 6 to the mounting frame 3, the mass motion variable is performed.

[0036] In order to be applicable to simulated linear motion under different resistance environments, a damping member 5 is installed between the two mounting frames 3. The damping member 5 is used to offset part of the potential energy generated by the spring 4 to simulate the resistance in the linear motion.

[0037] Example 2

[0038] See attached Figure 5 , which is different from Example 1 in that: the number of 6 springs 4 is changed to 7, wherein the added first new spring 41 is on the same axis as the first spring 4, and the first new spring 41 is mounted on an adjacent mounting frame 3. The purpose of such arrangement is that the plurality of springs 4 on the same plane and the same axis can reasonably utilize the radial area and reduce the thickness of the energy storage device of a single spring 4.

[0039] Example 3

[0040] See attached Figure 6 , which is different from Example 1 in that: the 6 springs 4 are changed to 7, wherein the added second new spring 42 is arranged alternately with the axis line of the first spring 4, and the second new spring 42 and the spring 4 are installed on the same two mounting frames 3; the purpose of such arrangement is to be suitable for occasions where the installation location has a small area and a large length.

[0041] Based on Examples 1-3, the device can simulate the energy storage density and shock absorption effect of the spring. Taking the automobile braking system as an example, when there is no motor for braking, the kinetic energy of the automobile during braking is converted into the potential energy of the spring. On the basis of traditional braking, by improving the installation position and the optimal number of springs, the best choice for automobile braking can be simulated based on the linear motion state, so as to shorten the braking time and shorten the braking distance; at the same time, the work of several springs can play a certain buffering and shock absorption effect.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

Any figure mark in the claims should not be regarded as limiting the claims involved.
