DETAILED DESCRIPTION

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0024] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a lightweight shift fork lever assembly structure for new energy vehicles of the present invention includes a shift fork seat 1, a shift fork hole is provided at the center of the shift fork seat 1, connecting seats 2 are provided on both sides of the shift fork seat 1, one end of the connecting seat 2 is abutted, and an assembly space is formed between the other ends of the connecting seat 2, and an assembly plate 4 is provided in the assembly space for squeezing the connecting seat 2 outward and bringing the connecting seat 2 closer to each other, arc-shaped channels are provided on the opposite surfaces of the assembly plate 4 and the connecting seat 2, adjacent arc-shaped channels are combined to form positioning holes 10, positioning columns 6 are inserted into the positioning holes 10, and fork arms 3 are installed on the outer sides of the connecting seat 2.

[0026] In this embodiment, slide grooves 13 are provided on both sides of the fork seat 1, and multiple connecting blocks 16 are installed at one end of the slide grooves 13. The connecting blocks 16 are all installed on the side of the connecting grooves. The connecting blocks 16 are all provided with arc-shaped positioning grooves 19. Slide blocks 15 are provided between the connecting blocks 16. Both sides of the sliders 15 protrude to form positioning parts 14. The positioning parts 14 are all slidably set in the positioning grooves 19. An entry and exit space for the sliders 15 to be taken out or loaded is formed between the positioning blocks and the other end of the slide grooves 13.

[0027] In this embodiment, a limiting groove 11 is provided on the outer ring surface of the fork seat 1 facing the assembly plate 4, and a limiting portion 20 is protruded on the inner side surface of the assembly plate 4. The limiting portion 20 is inserted into the limiting groove 11. The assembly plate can be positioned by the limiting portion and the limiting groove, thereby avoiding circumferential rotation of the assembly plate and increasing the stability of the installation.

[0028] In this embodiment, one end of the arc channel is expanded outward to form an arc groove 5, and adjacent arc grooves 5 are combined to form a feeding trough with a funnel-shaped structure, so that the opening of the positioning hole is opened outward, increasing the space, allowing the positioning column to be better inserted and the positioning column to be pushed out more conveniently.

[0029] In this embodiment, the diameter of the positioning column 6 matches the inner diameter of the positioning hole 10, and a guide groove 7 is provided on the arc-shaped channel of the assembly plate 4. The outer ring surface of the positioning column 6 protrudes opposite the guide groove 7 to form a guide bar 8, and the guide bar 8 is slidably set in the guide groove 7. The positioning column can restrict the assembly plate and the connecting seat together, so that the assembly plate cannot be removed upward from between the connecting seats. The positioning column is made of steel, which increases the firmness and reduces the probability of breakage.

[0030] In this embodiment, a groove is provided in the middle of the positioning column 6, and the groove is arranged toward the arc-shaped channel of the connecting seat 2. A through hole 9 is provided on the outer side surface of the connecting seat 2 facing the groove, and a plug column 17 is provided in the groove. One end of the plug column 17 is inserted into the through hole 9, and the other end is installed with a compression spring. The other end of the compression spring is installed on the inner wall surface of the groove. The compression spring can automatically push the plug column outward so that the plug column can be automatically inserted into the through hole, and the positioning column can be axially positioned by the plug column.

[0031] In this embodiment, the outer ring surfaces of the connecting seat 2 and the assembly plate 4 are arranged flush with each other, thereby avoiding unevenness that may affect subsequent use.

[0032] In this embodiment, the fork arm 3 on one side is recessed to form a slot 12, and the fork arm 3 on the other side protrudes opposite to the slot 12 to form an inserting portion 18, which is inserted into the slot 12. The fork arms 3 are relatively fitted together, and the fork arms 3 are combined to form a fork with an arc surface. The fork arms can be arranged horizontally relative to each other through the slot and the inserting portion, which increases the stability between the fork arms and avoids misalignment between the fork arms.

[0033] During installation, the slider on the connecting seat is inserted into the slide groove and moves inward along the slide groove, and the slider slides into between the connecting blocks. The positioning part on the connecting block can enter the positioning groove, which can position the inserted slider and avoid direct outward removal.

[0034] After the above is completed, install the assembly plate from top to bottom. As the assembly plate moves downward, the two ends of the assembly plate can squeeze the connecting seat, so that the connecting seat can move inward and press together to ensure stability after installation;

[0035] After the assembly plate is installed, a positioning hole is formed between the assembly plate and the connecting seat. At this time, the plug-in column is squeezed inward and inserted into the positioning hole. The guide bar on the positioning column can slide into the guide groove to prevent the positioning column from rotating. After the positioning column moves to the middle, the rebound of the compression spring can push the plug-in column outward so that the plug-in column can be inserted into the through hole. The positioning column can be positioned by plugging into the through hole to prevent the positioning column from falling out of the positioning hole.

[0036] Among them, the positioning column can fix the assembly plate and the connecting seat together to avoid separation, and as the positioning column is inserted, the assembly plate and the connecting seat can be further squeezed outward, so that the assembly plate and the connecting seat can be firmly pressed together to ensure stability after installation and avoid loosening.

[0037] On the contrary, when it needs to be replaced, prepare any metal rod, pass one end of the metal rod through the through hole and squeeze the plug inward, so that the positioning post can be pushed outward and disengaged from the positioning hole. After losing the obstruction of the positioning post, the assembly plate can be taken out upward from between the connecting seats. After losing the obstruction of the assembly plate, the connecting seat can be lifted up along the slide groove and directly taken out to complete the disassembly of the fork seat and the fork arm, making it convenient for their independent replacement.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
