[0031] Reference below Figure 1-Figure 2 The following describes a rotating shaft frame 100 , a rotating shaft assembly, and a vehicle according to an embodiment of the present invention.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a rotating shaft frame 100.

[0034] The rotating shaft frame 100 includes a fixed base 1 and a base 2. Both the fixed base 1 and the base 2 have through-holes extending in a first direction, and the through-holes of the fixed base and the base are connected to accommodate the rotating shaft. In one specific embodiment, the base 2 has a first first rotating hole and a first second rotating hole extending in the first direction, and the fixed base 1 has a second first rotating hole and a second second rotating hole extending in the first direction. The first first rotating hole and the second first rotating hole are connected to accommodate one rotating shaft, and the first second rotating hole and the second second rotating hole are connected to accommodate the other rotating shaft.

[0035] The fixing base 1 is fixed in the mounting groove 210 . One end of the fixing base 1 in the first direction has a first inclined surface 11 , and one end of the base 2 in the first direction has a second inclined surface.

[0036] The first inclined surface 11 and the second inclined surface 21 have the same inclination angle, and cooperate with each other to make the end of the base 2 facing away from the fixing base 1 in the first direction abut against the groove wall of the installation groove 210 .

[0037] The base 2 and the fixing base 1 are locked together by the inclined surface, thereby improving the stability and reliability of the cooperation between the base 2 and the fixing base 1.

[0038] In a specific application scenario, after the fixing base 1 is fixed to the mounting groove 210, the first inclined surface 11 is opposite to the groove wall of the mounting groove 210. The spacing between the first inclined surface 11 and the groove wall of the mounting groove 210 in the first direction gradually changes. The installation position of the base 2 can be slightly adjusted. For example, when there is still a certain gap between the base 2 and the groove wall of the mounting groove 210, the base 2 is pushed and moved relative to the fixing base 1, and the second inclined surface 21 on the base 2 slides and cooperates with the first inclined surface 11 on the fixing base 1 until the two ends of the base 2 respectively abut the fixing base 1 and the groove wall of the mounting groove 210.

[0039] In the related art, the rotating shaft frame is an integrated structure. The applicant separated the integrated rotating shaft frame into a combined fixing base 1 and base 2, and adjusted the size of the rotating shaft frame 100 in the first direction through the first inclined surface 11 on the fixing base 1. This allows the rotating shaft frame 100 to expand from both ends in the first direction to press against the groove wall of the mounting groove 210 (i.e., the vehicle frame 200), thereby reducing the assembly gap between the rotating shaft frame 100 and the mounting groove 210 and improving safety.

[0040] In combination with the technical solution, it can be seen that the embodiment provided by the present invention has the following advantages: (1) The base 2 and the fixed seat 1 are locked together by the inclined surface, which improves the stability and reliability of the cooperation between the base 2 and the fixed seat 1. The position of the base 2 can be adjusted. Through the cooperation between the first inclined surface 11 and the second inclined surface 21, the base 2 is simultaneously in contact with the fixed seat 1 and the groove wall of the installation groove 210, reducing the gap between the rotating shaft frame 100 and the installation groove 210, compensating for the errors generated by the rotating shaft frame 100 or the installation groove 210 during the production process, reducing the shaking caused by low manufacturing precision, and improving the cooperation precision and safety between the installation groove 210 and the rotating shaft frame 100; (2) reducing the requirements for the processing precision of the rotating shaft frame 100 and the installation groove 210, reducing the difficulty of the manufacturing and processing technology, reducing costs, and improving production efficiency.

[0041] like Figure 1 and Figure 2As shown, the rotating shaft frame 100 further has a first side 101 and a second side 142 in a second direction, the second direction being perpendicular to the first direction. The first side 101 of the mounting slot 210 is open and forms an opening for mounting the rotating shaft frame 1. The first inclined surface 11 gradually inclines along the first direction and along the first side 101 toward the second side 102. That is, in the direction from the first side 101 to the second side 102 (i.e., the direction in which the base 2 is inserted into the mounting slot 210), the distance in the first direction between the first inclined surface 11 and the groove wall of the mounting slot gradually decreases. The rotating shaft frame 100 also includes an adjustment member 3, which is capable of driving the base 2 to move relative to the fixed base 1. The adjustment member is used to drive the base 2 to move in the second direction relative to the fixed base 1. The adjustment member 3 is capable of driving the base 2 to move relative to the fixed base 1 from the first side 101 to the second side 102.

[0042] like Figure 1 and Figure 2 As shown, further, the adjusting member 3 and the fixing seat 1 respectively abut against opposite sides of the base 2 in the second direction, and the adjusting member 3 is movably mounted in the fixing seat 1 along the second direction. Specifically, the adjusting member 3 is used to abut against the first side 101 of the base 2, and the adjusting member 3 is movably mounted in the fixing seat 1, and the adjusting member 3 can move along the second direction. In the second direction, the base 2 is fixed between the adjusting member 3 and the fixing seat 1, that is, the adjusting member 3 abuts against the first side 101 of the base 2, and the supporting force of the first inclined surface 11 has a component parallel to the second direction, and the component of the supporting force in the second direction acts on the second side 102 of the base 2.

[0043] like Figure 1 and Figure 2 As shown, further, the adjusting member 3 includes a stud 31 and a flange portion 32 connected to the end of the stud 31, and a screw hole 12 extending along the second direction is opened in the fixing base 1, and the stud 31 is threadedly engaged in the screw hole 12 so that the flange portion 32 abuts the first side 101 of the base 2.

[0044] like Figure 1 and Figure 2 As shown, further, the base 2 is formed with a recessed groove 22 on the first side 101 for embedding the flange portion 32. By providing the recessed groove 22, the flange portion 32 can be located in the recessed groove 22, making the structure of the rotating shaft frame 100 more compact and improving the space utilization of the rotating shaft frame 100.

[0045] like Figure 1 and Figure 2 As shown, further, a gasket 5 is provided between the flange portion 32 and the sink 22 to reduce the adverse effects such as wear and vibration that may be caused by direct contact between the flange portion 32 and the sink 22.

[0046] Example 2

[0047] like Figure 1 and Figure 2 As shown, this embodiment is substantially the same as the first embodiment, with the following differences: both end surfaces of the fixing base 1 in the first direction are first inclined surfaces 11, and there are two bases 2, which respectively abut and engage with both ends of the fixing base 1 in the first direction. In conjunction with the above embodiment, the distance between the two first inclined surfaces 11 in the first direction gradually increases from the first side to the second side.

[0048] Specifically, after the fixing base 1 is secured in the mounting groove 210 through the opening of the mounting groove 210, the distance between one first inclined surface 11 of the fixing base 1 in the first direction and the groove wall of the mounting groove 210 gradually decreases along the direction from the first side 101 to the second side 102. Similarly, the distance between another first inclined surface 11 of the fixing base 1 in the first direction and the groove wall of the other mounting groove 210 gradually decreases along the direction from the first side to the second side. As a result, the rotating shaft frame 100 can simultaneously expand from both ends in the first direction to support the groove wall of the mounting groove 210 (i.e., the vehicle frame 200), further reducing assembly errors and the possibility of frame 200 shaking due to insufficient assembly precision.

[0049] Example 3

[0050] like Figure 1 and Figure 2 As shown, this embodiment is basically the same as the first embodiment, with the difference being that the first inclined surface 11 and the second inclined surface 21 are in contact with each other and have the same inclination angle.

[0051] Example 4

[0052] This embodiment provides a rotating shaft assembly, which includes a rotating shaft frame 100, a first rotating shaft, and a second rotating shaft. The first rotating shaft is inserted into one rotating hole 4, and the second rotating shaft is inserted into the other rotating hole 4. The two rotating holes 4 of the rotating shaft frame 100 are spaced apart along a third direction, and the first direction and the second direction are perpendicular to the third direction.

[0053] The first rotating shaft is passed through one rotating hole 4 , and the second rotating shaft is passed through the other rotating hole 4 .

[0054] The base 2 is provided with a first rotating hole and a first second rotating hole that pass through in the first direction, and the first rotating hole and the first second rotating hole are spaced apart along the third direction; the fixed base 1 is provided with a second first rotating hole and a second second rotating hole that pass through in the first direction, and the second first rotating hole and the second second rotating hole are spaced apart along the third direction, the first first rotating hole is connected with the second first rotating hole to accommodate the first rotating shaft, and the first second rotating hole is connected with the second second rotating hole to accommodate the second rotating shaft.

[0056] This embodiment provides a vehicle comprising a frame 200 and a rotating shaft assembly. The frame 200 comprises a first body and a second body that rotate relative to each other. A mounting slot 210 is provided at the rotating connection between the first and second bodies. The mounting slot 210 comprises a first half slot formed on the first body and a second half slot formed on the second body. A rotating shaft frame 100 is disposed within the mounting slot 210. A first rotating shaft extends through a rotating hole 4 and the first body, while a second rotating shaft extends through another rotating hole 4 and the second body.
