Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Such as Figures 1 to 16As shown, the mounting component of the printed circuit board of this new energy vehicle of the present invention, the mounting component 1 includes a printed circuit board 2, a mounting piece 3, a positioning piece 4, and a limiting piece 5. The limiting piece 5 is hinged on both sides of the positioning piece 4, and the positioning piece 4 is mounted on the printed circuit board 2 after being deformed by force, so as to limit the printed circuit board 2 in the middle of the mounting piece 3 through the positioning piece 4. When installing the printed circuit board 2, the printed circuit board 2 can be directly inserted into the middle of the mounting piece 3. Under the cooperation of the first magnetic part 6 and the second magnetic part 7, the limiting piece 5 is restricted, so as to position the position of the printed circuit board 2. When it is necessary to remove the printed circuit board 2, press the printed circuit board 2 downward again, so that the printed circuit board 2 continues to compress the spring 8, and under the guidance of the guiding inclined surface 14, the lower end of the limiting piece 5 opens to both sides, while the upper end of the limiting piece 5 moves closer to the middle. Make the distance value between the limiting piece 5 and the upper end of the limiting piece 5 less than the length of H1, which is convenient for pushing the positioning piece 4 to move upward under the elastic force of the spring 8, and keep the limiting piece 5, the positioning piece 4 and the printed circuit board 2 all enter between the limiting parts 9 and the limiting parts 9, so as to take out the printed circuit board 2.

[0040] An opening 10 is provided at the lower end of the printed circuit board 2, and symmetric first bayonets 11 are provided in the opening 10. Symmetric insertion ends 12 are formed on both sides of the opening 10, and the insertion ends 12 are matched with the insertion slots 13. When the first magnetic part 6 and the second magnetic part 7 on the printed circuit board 2 are in contact and cooperate, at this time, the insertion ends 12 on the printed circuit board 2 can still continue to be inserted into the insertion slots 13, so as to facilitate the continuous compression of the spring 8 and keep the guiding inclined surface 14 guiding the lower end of the limiting piece 5 to open. The insertion ends 12 are the same, so that the printed circuit board 2 can be inserted into the insertion slots 13 in both positive and negative directions.

[0041] The inner wall of the opening 10 is the fourth wall surface 15, and the distance between the fourth wall surface 15 and the fifth wall surface 16 arranged inside the first bayonet 11 is H4. The length of the second bayonet 17 is matched with H4, so that the first bayonet 11 and the second bayonet 17 can be engaged and limited with each other. The length of the second bayonet 17 is half of the length of the first hinge part 18, and the length of the first hinge part 18 is twice that of H4.

[0042] As Figure 9 and 10As shown, first apply pressure to the middle of the positioning member 4 in the direction of F1, keeping the two ends of the positioning member 4 moving towards the middle, that is, keeping the two ends of the positioning member 4 moving in the direction of F2. When the length of the positioning member 4 in the normal state is S1, and the length of the positioning member 4 when the middle is stressed is S2, S1 > S2. The second bayonet 17 has a sixth inner wall 19, and the distance between the sixth inner walls 19 is H5, H5 < S2, so that the bent positioning member 4 can be installed into the first bayonet 11 in the opening 10, realizing the installation of the positioning member 4 through the cooperation of the second bayonet 17 and the first bayonet 11. This can not only ensure that the positions of the positioning members 4 do not move, but also improve the strength of the insertion end 12.

[0043] A through area 20 for installing the printed circuit board 2 is formed in the middle of the mounting member 3. The mounting member 3 is composed of a bottom plate 21, an insertion seat 22 and a support seat 23. The support seat 23 is connected to the bottom plate 21, and the insertion seat 22 is connected to the support seat 23. An insertion slot 13 for cooperating with the printed circuit board 2 is formed in the middle of the insertion seat 22. Conductive contact pieces for cooperating with the insertion ends 12 on the printed circuit board 2 are provided in the insertion slot 13, realizing the electrical connection between the printed circuit board 2 and the insertion slot 13 in the middle of the mounting member 3.

[0044] Symmetrically arranged holding arms 24 are provided on the support seat 23. The holding arms 24 are composed of an elastic part 25 and a limiting part 9, and the elastic part 25 can deform when stressed. The thickness of the limiting part 9 is greater than the thickness of the elastic part 25, so that when the limiting member 5 is at the lower end of the limiting part 9, the upper end of the limiting member 5 can be restricted by the limiting part 9, thus preventing the printed circuit board 2 from being ejected by the spring 8.

[0045] A guiding area 26 is formed between the limiting parts 9. Guiding inclined surfaces 27 are provided on the limiting parts 9. The guiding inclined surfaces 27 are used to guide the limiting member 5, and can guide the limiting member 5 at different inclination angles, so that when the limiting member 5 is in different inclined states, it can be guided into the through area 20 for installation without manually adjusting the angle of the limiting member 5.

[0046] The inner wall surface of the limiting part 9 forms a first wall surface 28, and the inner wall surface of the elastic part 25 forms a second wall surface 29. The distance between the first wall surfaces 28 is H1, and the distance between the second wall surfaces 29 is H2, H1 < H2. The outer wall surface of the limiting member 5 is a third wall surface 30. When the third wall surface 30 is arranged in a vertical state, the distance between the third wall surfaces 30 is H3, H1 = H3 < H2.

[0047] In the middle of the insertion slot 13, there are symmetrically arranged arc-shaped openings 31. A spring 8 is arranged in the arc-shaped opening 31. The lower end of the spring 8 is placed in the insertion slot 13, and the upper end contacts the positioning member 4. The spring 8 is arranged in the insertion slot 13 and the arc-shaped opening 31 to limit the position of the spring 8. The arc-shaped opening 31 and the spring 8 are in interference fit to prevent the spring 8 from falling out, thus affecting the installation of the printed circuit board 2.

[0048] At the connection between the limiting portion 9 and the elastic portion 25, there is a receiving area 32 that cooperates with the limiting member 5. After the limiting member 5 is installed, its position can be restricted through the receiving area 32, enabling it to only move downward and not in other directions.

[0049] On the support base 23, there is a guiding inclined surface 14. A guiding area 33 is formed between the guiding inclined surface 14 and the elastic portion 25. The guiding inclined surface 14 can guide the lower end of the limiting member 5, enabling the lower end of the limiting member 5 to remain open, so that the upper end of the limiting member 5 remains close together. The distance after the upper ends are close together is less than the width of H1. Under the elastic force of the spring 8, the positioning member 4 is pushed upward to remove the printed circuit board 2.

[0050] The positioning member 4 is arranged on the printed circuit board 2. At both ends of the positioning member 4, there are second bayonet joints 17 that cooperate with the first bayonet joints 11. At both ends of the positioning member 4, there are also first hinge portions 18 that are symmetrically arranged in pairs, and the first hinge portions 18 are located at the four corners of the positioning member 4. A hinge opening 34 is formed between the first hinge portions 18 that are symmetrically arranged on both sides of the positioning member 4, and a hinge rod 35 is arranged in the hinge opening 34.

[0051] The limiting member 5 is hingedly connected to the positioning member 4 and is hinged in the hinge opening 34. In the middle of one side of the limiting member 5, there is a second hinge portion 36 that cooperates with the first hinge portion 18. On the outer wall of the second hinge portion 36, there are multiple ball head protrusions 37. The ball head protrusions 37 can make the installation between the first hinge portion 18 and the second hinge portion 36 more compact. After the limiting member 5 is stressed and rotates around the hinge rod 35, when the external force is cancelled, it will not automatically reset and return to its original state, enabling it to always maintain this state without continued external force interference. Thus, it is convenient for the limiting member 5 to rotate after being guided by the guiding inclined surface 14. After being pushed upward by the spring 8 and passing through the second magnetic member 7, due to the increase in the distance between the first magnetic member 6 and the second magnetic member 7, the magnetic force of the second magnetic member 7 is insufficient, facilitating the direct passage of the first magnetic member 6 without being disturbed and rotating.

[0052] The limiting member 5 is composed of a guiding end 38 and a positioning end 39. The guiding end 38 is located at the lower end of the positioning end 39. In the middle of the positioning end 39, there is a first fixing area 40 for installing the first magnetic member 6. On the holding arm 24, there is a second fixing area 41 for installing the second magnetic member 7. The guiding end 38 and the positioning end 39 are not arranged parallel to each other, and the included angle between them is 15°.

[0053] The second hinge part 36 is connected to the first hinge part 18 through a hinge rod 35. A first magnetic member 6 is provided at the upper end of the limiting member 5, and a second magnetic member 7 that cooperates with the first magnetic member 6 is provided at the connection between the limiting part 9 and the elastic part 25.

[0054] As Figure 16 shown, when the limiting member 5 is in the vertical state in M2, the magnetic force of the second magnetic member 7 at this time can just attract the first magnetic member 6. When the limiting member 5 is in the state of M3, the second magnetic member 7 cannot attract the first magnetic member 6 at this time. The states of the limiting member 5 in M1, M2, and M3 are all different, but they can all be quickly installed into the through area 20 under the guidance of the guiding inclined surface 27. Only these three states are shown in this application, but it is not limited to other inclined angle states.

[0055] The printed circuit board 2 enters the through area 20 under the guidance of the guiding area 26. The first magnetic member 6 on the limiting member 5 is attracted by the second magnetic member 7, so that the positioning end 39 contacts the second wall surface 29. The spring 8 is compressed by the positioning member 4. After the limiting member 5 is attracted by the second magnetic member 7, the upper end of the limiting member 5 remains open, while the lower end closes, restricting the printed circuit board 2 to the middle of the mounting member 3.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
