[0037] like Figure 1-Figure 5 As shown, the gearbox flexible shaft bracket 1 according to the embodiment of the utility model includes a gear shift sub-bracket 100 and a gear selection sub-bracket 200 .

[0038] The shift sub-bracket 100 is suitable for being installed in a gearbox. The shift sub-bracket 100 has a first shift mounting position 110 and a second shift mounting position 120. One of the first shift mounting position 110 and the second shift mounting position 120 is suitable for mounting the shift flexible shaft 12. The gear selection sub-bracket 200 is installed on the shift sub-bracket 100.

Figure 1 The first shift installation position of the middle gear flexible shaft is indicated by a solid line, and the second shift installation position is indicated by a dotted line, and the gear selection flexible shaft is the same. According to the real-time driving conditions of different vehicles and other conditions, the first shift installation position 110 and the second shift installation position 120, the first gear selection installation position 210 and the second gear selection installation position 220 can be selected to meet the requirements of the gear shift flexible shaft and the gear selection flexible shaft installation of different vehicle models and gearbox types.

[0041] According to the gearbox flexible shaft bracket 1 of the embodiment of the utility model, it includes a shift sub-bracket 100 and a gear selection sub-bracket 200. The shift sub-bracket 100 and the gear selection sub-bracket 200 can selectively install the shift flexible shaft 12 in one of the first shift installation position 110 and the second shift installation position 120 according to the installation position requirements; similarly, the gear selection flexible shaft 13 can be selectively installed in one of the first gear selection installation position 210 and the second gear selection installation position 220.

This arrangement allows the installation positions of the gear shift flexible shaft 12 and the gear selection flexible shaft 13 to be flexibly adjusted as needed to adapt to the design and layout of different gearboxes. Therefore, only one universal gearbox flexible shaft bracket 1 is needed to meet the installation of the gear shift flexible shaft 12 and the gear selection flexible shaft 13 of different gearboxes, which can reduce the types of parts and components, thereby reducing the complexity and cost of the manufacturing process.

[0043] Therefore, the gearbox flexible shaft bracket 1 according to the embodiment of the utility model has the advantages of improving the versatility of use and reducing the manufacturing cost of the whole vehicle.

[0044] In some specific embodiments of the present invention, Figure 2-Figure 5 As shown, the shift sub-bracket 100 includes a bottom plate portion 101 and a shift mounting portion 102. The bottom plate portion 101 extends horizontally and is suitable for being mounted on a gearbox. The shift mounting portion 102 is connected to the bottom plate portion 101 and extends upward, and a first shift mounting position 110 and a second gear selection mounting position 120 are arranged at intervals along the extension direction of the shift mounting portion 102.

[0045] The gear selection sub-bracket 200 includes a top plate portion 201 and a gear selection side mounting portion 202. The top plate portion 201 is mounted on the gear shift mounting portion 102 and extends horizontally, and a first gear selection mounting position 210 is formed on the top plate portion 201. The gear selection side mounting portion 202 is mounted on the bottom plate portion 101 and extends upward, and the gear selection side mounting portion 202 is connected to the top plate portion 201, and a second gear selection mounting position 220 is formed on the gear selection side mounting portion 202.

[0046] The shift sub-bracket 100 is constructed by constructing a bottom plate portion 101 and a shift mounting portion 102, and the gear selection sub-bracket 200 is constructed by constructing a top plate portion 201 and a gear selection side mounting portion 202. The gear selection sub-bracket 200 and the shift sub-bracket 100 are connected to each other. The shift sub-bracket 100 and the gear selection sub-bracket 200 are both formed by bending a sheet structure, so that the gearbox flexible shaft bracket 1 has the advantage of being lightweight, and the structural strength of the shift sub-bracket 100 is increased, so that it can better withstand the pressure and vibration of the gearbox.

[0047] By arranging the first gear shift mounting position 110 and the second gear shift mounting position 120 at different positions of the gear shift mounting portion 102, the installation requirements of the gear shift flexible shaft 12 of different gearboxes can be met. At the same time, by arranging the first gear selection mounting position 210 and the second gear selection mounting position 220 at the top plate portion 201 and the gear selection side mounting portion 202, the installation requirements of the gear selection flexible shaft 13 of different gearboxes can be met.

[0048] In some specific embodiments of the present invention, Figure 1and Figure 2 As shown, the first shift mounting position 110 is located on the side of the shift mounting portion 102 facing away from the gear selection side mounting portion 202. In addition, the second shift mounting position 120 is also located on the side of the shift mounting portion 102 facing away from the gear selection side mounting portion 202. By rationally utilizing the space, the gearbox flexible shaft bracket 1 is provided with multiple mounting positions in the effective space, and the first shift mounting position 110 and the second shift mounting position 120 do not interfere with each other. Similarly, the first gear selection mounting position 210 and the second gear selection mounting position 220 are spatially separated, and the gearbox flexible shaft bracket 1 can better realize its function when it is installed on different gearboxes.

[0049] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the first gear selection installation position 210 is located at the bottom of the top plate portion 201, and the second gear selection installation position 220 is located on the side of the gear selection side installation portion 202 that is opposite to the gear shift installation portion 102. For example, the gear shift installation portion 102 and the gear selection side installation portion 202 are located on opposite sides of the bottom plate portion 101, and the bottom plate portion 101 and the top plate portion 201 are located on opposite sides of the vertical space. A space is reserved in the middle position of the gearbox flexible shaft bracket 1, so that the first gear selection installation position 210 can pass through it to realize its corresponding function, and the second gear selection installation position 220 is located on the opposite side of the gear selection side installation portion 202, which reduces the spatial position intersection with the first gear selection installation position 201 and improves the space utilization rate.

[0050] In some specific embodiments of the present invention, the top plate portion 201 and the bottom plate portion 101 are parallel to each other. Figure 5 As shown in the angle A in , the angle between the plane where the shift mounting portion 102 is located and the plane where the gear selection side mounting portion 202 is located is an acute angle. The shift flexible shaft 12 extends along the plane where the shift mounting portion 102 is located, and the gear selection flexible shaft 13 extends along the plane where the gear selection side mounting portion 202 is located. The angle between the shift flexible shaft 12 and the gear selection flexible shaft 13 is small, and the shift flexible shaft 12 and the gear selection flexible shaft 13 can be extended to the gearbox more smoothly for shifting and selecting gears. The shift flexible shaft 12 and the gear selection flexible shaft 13 have less bending deformation, which improves the operating comfort and reliability. The top plate portion 201 and the bottom plate portion 101, which are parallel to each other, can provide stable support and fixation, effectively withstand the force from the gearbox, and ensure the stability and reliability of the vehicle during driving. At the same time, the vibration and stress concentration of the gearbox flexible shaft bracket 1 are reduced, so that it can withstand greater force and load.

[0051] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the first gear shift installation position 110 is located above the top plate portion 201 , and the second gear shift installation position 120 is located below the top plate portion 201 .

[0052] The shift flexible shaft 12 can selectively pass above or below the top plate according to space requirements, making full use of the space of the gearbox flexible shaft bracket 1, and the extension path of the shift flexible shaft 12 will not interfere with the various structures of the gearbox flexible shaft bracket 1.

[0053] In some specific embodiments of the present invention, Figure 1 As shown, the gearbox flexible shaft bracket 1 also includes a plurality of fixing components 300, wherein one fixing component 300 is installed at one of the first gear shift mounting position 110 and the second gear shift mounting position 120 to install the gear shift flexible shaft 12, and another fixing component 300 is installed at one of the first gear selection mounting position 210 and the second gear selection mounting position 220 to install the gear selection flexible shaft 30.

[0054] By respectively cooperating multiple fixing components 300 with the first gear shift mounting position 110 and the second gear shift mounting position 120, the first gear selection mounting position 210 and the second gear selection mounting position 220, the gear shift flexible shaft 12 and the gear selection flexible shaft 13 can be firmly fixed on the gearbox flexible shaft bracket 1, ensuring that the gearbox flexible shaft bracket 1 will not loosen or move during operation, thereby ensuring the accuracy and stability of the gear shifting and gear selection operations.

[0055] At the same time, during the gear shifting and selecting process, the gear shifting flexible shaft 12 and the gear selecting flexible shaft 13 need to withstand certain push and pull forces, and the fixing member 300 ensures the stability and reliability of the gear shifting flexible shaft 12 and the gear selecting flexible shaft 13 by providing force points and support points.

[0056] In some specific embodiments of the present invention, Figure 1 As shown, the fixing assembly 300 includes a first pressing block 310, a second pressing block 320 and a fastener 330. The first pressing block 310 of one fixing assembly 300 is installed on the gear shift sub-bracket 100, and the second pressing block 320 and the first pressing block 310 are respectively located on opposite sides of the gear shift flexible shaft 12. The first pressing block 310 of another fixing assembly 300 is installed on the gear selection sub-bracket 200, and the second pressing block 320 and the first pressing block 310 are respectively located on opposite sides of the gear selection flexible shaft 30. The fastener 330 is disposed through the first pressing block 310 and the second pressing block 320 and fixes the first pressing block 310 and the second pressing block 320 together.

[0057] The first pressing block 310 and the second pressing block 320 are consistent in size and shape, and the fastener 330 passes through the first pressing block 310 and the second pressing block 320 to fix the shift flexible shaft 12 and the gear selection flexible shaft 13.

[0058] The first pressing block 310 and the second pressing block 320 are fixed together by the fastener 330, so that the stress points of the gearbox flexible shaft bracket 1 can be dispersed to multiple fixed points, reducing the stress concentration between the shift flexible shaft 12 and the gear selection flexible shaft 13, and extending the service life of the shift flexible shaft 12 and the gear selection flexible shaft 13.
