[0040] According to the subframe assembly of the embodiment of the utility model, a first clamping structure 1 is provided on the electric drive axle 100, and a second clamping structure 2 is provided on the subframe, so that the electric drive axle 100 can be clamped and connected with the second clamping structure 2 through the first clamping structure 1, and then installed on the subframe. The installation process is simple, which facilitates the installation of the electric drive axle 100 on the subframe, thereby shortening the production time, improving the production efficiency, and reducing the production cost, with better use effect and a wider range of application.

[0041] In some embodiments, one of the first clamping structure 1 and the second clamping structure 2 is configured to have a clamping space 23 and the other is configured to include a clamping block 11 , and the clamping block 11 is clamped into the clamping space 23 .

[0042] Specifically, one of the first clamping structure 1 and the second clamping structure 2 is constructed to have a clamping space 23 and the other is constructed to include a clamping block 11. That is, the first clamping structure 1 can be constructed to have a clamping space 23 and the second clamping structure 2 can be constructed to include the clamping block 11, or the second clamping structure 2 can be constructed to have a clamping space 23 and the first clamping structure 1 can be constructed to include the clamping block 11.

[0043] Furthermore, if Figure 1-Figure 3 As shown, in the present embodiment, the first clamping structure 1 is constructed to include a clamping block 11, the second clamping structure 2 is constructed to have a clamping space 23, and the clamping block 11 matches the shape of the clamping space 23, so that the clamping block 11 can be clamped into the clamping space 23, that is, when the first clamping structure 1 and the second clamping structure 2 are clamped, the clamping block 11 can be placed in the clamping space 23, so that the first clamping structure 1 and the second clamping structure 2 are clamped and connected, thereby allowing the electric drive axle 100 to be installed on the subframe, the installation method is simple, and the production efficiency can be improved.

[0044] In some embodiments, one of the first clamping structure 1 and the second clamping structure 2 includes a mounting member 21 and a movable member 22, the movable member 22 can be movably mounted on the mounting member 21 and defines a clamping space 23 with the mounting member 21, and an elastic member 224 is connected between the movable member 22 and the mounting member 21, and the elastic member 224 is used to apply an elastic force to the movable member 22 to move toward the clamping space 23.

[0045] Specifically, one of the first clamping structure 1 and the second clamping structure 2 includes a mounting member 21 and a moving member 22, that is, the first clamping structure 1 is configured to include the mounting member 21 and the moving member 22, and the second clamping structure 2 is configured to include the mounting member 21 and the moving member 22. Figure 3 As shown, in this embodiment, the second clamping structure 2 is configured to include a mounting member 21 and a movable member 22. The second clamping structure 2 is arranged on the sub-frame, that is, the mounting member 21 and the movable member 22 are also arranged on the sub-frame. The mounting member 21 can be integrally formed with the sub-frame, and the mounting member 21 can also be fixedly connected to the sub-frame by welding or the like, and the movable member 22 can be movably mounted on the mounting member 21, that is, the movable member 22 is movable relative to the mounting member 21, so that the movable member 22 is movable relative to the sub-frame.

[0046] Furthermore, if Figure 3As shown, the mounting member 21 and the movable member 22 are connected and jointly define a clamping space 23. The movable member 22 is movable relative to the mounting member 21, that is, when the movable member 22 moves relative to the mounting member 21, the clamping space 23 is variable, and an elastic member 224 is arranged between the movable member 22 and the mounting member 21. The elastic member 224 can be arranged as a spring, etc. One end of the elastic member 224 is connected to the movable member 22, and the other end is connected to the mounting member 21. When the movable member 22 moves in a direction away from the mounting member 21, the elastic member 224 is stretched, so that the elastic member 224 can apply an elastic force to the movable member 22 to move toward the clamping space 23.

[0047] When the movable member 22 moves toward a direction away from the mounting member 21, the engaging space 23 becomes larger, and the first engaging structure 1 can be partially placed in the engaging space 23, so that the first engaging structure 1 and the second engaging structure 2 can be engaged, and when the elastic member 224 applies an elastic force to the movable member 22, the movable member 22 can move toward the engaging space 23, thereby completing the engaging of the first engaging structure 1 and the second engaging structure 2. The engaging method is simple, which can increase the connection speed and thus improve the production efficiency.

[0048] In some embodiments, the locking block 11 is formed with a locking protrusion 111, the moving part 22 is formed with a locking groove 221, a locking stop surface 222 is formed in the locking groove 221, and the locking protrusion 111 is formed with a locking guide surface 112 and a limit stop surface 113; the locking protrusion 111 is suitable for pushing the moving part 22 to move in a direction away from the locking space 23 through the locking guide surface 112, so that the locking protrusion 111 extends into the locking groove 221 and the limit stop surface 113 is limited and pressed against the locking stop surface 222.

[0049] Specifically, the first clamping structure 1 is provided with a clamping block 11, and the clamping block 11 can be placed in the clamping space 23, so that the first clamping structure 1 can be clamped and connected with the second clamping structure 2, and Figure 1-Figure 3 as well as Figure 5 As shown, the clamping block 11 is formed with a clamping protrusion 111, and the moving member 22 is formed with a clamping groove 221. The clamping protrusion 111 and the clamping groove 221 are correspondingly arranged. When the clamping protrusion 111 is placed in the clamping groove 221, the first clamping structure 1 and the second clamping structure 2 can be clamped and connected.

[0050] Furthermore, the engaging protrusion 111 is formed with an engaging guide surface 112, and the engaging guide surface 112 is inclined along the engaging direction. In the engaging process, the engaging guide surface 112 of the engaging protrusion 111 first contacts the moving member 22, so that when the engaging protrusion 111 moves along the engaging direction, the engaging guide surface 112 can push the moving member 22 to move in a direction away from the engaging space 23, thereby expanding the engaging space 23, so that the engaging block 11 can be placed in the engaging groove 221, and a engaging stopper is formed in the engaging groove 221. The surface 222 and the clamping protrusion 111 form a limited stop surface 113. When the clamping protrusion 111 is placed in the clamping groove 221, the elastic member 224 applies an elastic force to the movable member 22, so that the movable member 22 moves toward the direction close to the clamping space 23, so that the limit stop surface 113 can be limited and pressed against the clamping stop surface 222. The limit stop surface 113 and the clamping stop surface 222 are distributed along the clamping direction, so as to limit the displacement of the first clamping structure 1 and the second clamping structure 2 along the clamping direction, thereby ensuring the clamping reliability.

[0051] In some embodiments, the clamping protrusions 111 and the clamping grooves 221 are multiple and matched one by one, and the multiple clamping protrusions 111 are distributed in sequence and spaced apart along the clamping direction of the clamping block 11 and the clamping space 23 .

[0052] Specifically, Figure 2 and Figure 5 As shown, the clamping block 11 is formed with a clamping protrusion 111, and the moving part 22 is formed with a clamping groove 221. When the clamping protrusion 111 is placed in the clamping groove 221, the first clamping structure 1 and the second clamping structure 2 can be connected by clamping, and the clamping protrusion 111 is set to multiple, and the clamping groove 221 is also set to multiple. The multiple clamping protrusions 111 and the multiple clamping grooves 221 are arranged in a one-to-one correspondence, that is, the multiple clamping protrusions 111 can be placed in the corresponding clamping grooves 221 for clamping, which can improve the clamping reliability.

[0053] Furthermore, multiple clamping protrusions 111 are distributed in sequence along the clamping direction of the clamping block 11 and the clamping space 23, and multiple clamping grooves 221 are also distributed in sequence along the clamping direction of the clamping block 11 and the clamping space 23 on the movable block. As a result, during the clamping process of the first clamping structure 1 and the second clamping structure 2 along the clamping direction, multiple clamping protrusions 111 can be clamped with multiple clamping grooves 221 in sequence, and when the clamping is completed, multiple clamping protrusions 111 can all be clamped with corresponding clamping grooves 221, thereby improving the clamping reliability. When there is a movement tendency along the clamping direction between the first clamping structure 1 and the second clamping structure 2, a force will be generated on the clamping protrusion 111, and the force can be dispersed to each clamping protrusion 111, thereby avoiding the situation where a single clamping protrusion 111 is subjected to excessive force and causes breakage, thereby extending the service life of the clamping protrusion 111.

[0054] In some embodiments, one of the mounting member 21 and the moving member 22 is provided with a sliding guide groove 214 and the other is provided with a sliding guide rail 223 , and the sliding guide rail 223 is slidably matched with the sliding guide groove 214 .

[0055] Specifically, one of the mounting member 21 and the moving member 22 is provided with a sliding guide groove 214 and the other is provided with a sliding guide rail 223, that is, the mounting member 21 is provided with a sliding guide groove 214, and the moving member 22 is provided with a sliding guide rail 223, or the mounting member 21 is provided with a sliding guide rail 223, and the moving member 22 is provided with a sliding guide groove 214.

[0056] Furthermore, a card-connecting space 23 is defined between the movable member 22 and the mounting member 21, and the movable member 22 can move toward or away from the card-connecting space 23. The mounting member 21 is provided with a sliding guide groove 214, and the movable member 22 is provided with a sliding guide rail 223, and the sliding guide rail 223 is slidingly matched with the sliding guide groove 214, that is, the movable member 22 can be moved relative to the mounting member 21 through the sliding guide rail 223 and the sliding guide groove 214 slidingly matched, thereby ensuring the movement path of the movable member 22, and the elastic member 224 can be arranged in the sliding guide rail 223, and the direction of the elastic force of the elastic member 224 is the same as the extension direction of the sliding guide rail 223.

[0057] In some embodiments, the mounting member 21 includes a base plate 211, a first side plate 212 and a second side plate 213. The first side plate 212 and the second side plate 213 are vertically connected and are respectively vertically connected to the base plate 211. A snap-in space 23 is defined between the movable member 22 and the first side plate 212, and the movable member 22 is slidably matched with the second side plate 213 and / or the base plate 211.

[0058] Specifically, Figure 4 As shown, the mounting member 21 is provided with a bottom plate 211, a first side plate 212 and a second side plate 213. The bottom plate 211 is arranged at the bottom of the mounting member 21. The first side plate 212 and the bottom plate 211 are vertically connected. The second side plate 213 is also vertically connected to the bottom plate 211. The first side plate 212 and the second side plate 213 are also vertically connected. A clamping space 23 is defined between the movable member 22 and the first side plate 212. That is, when the movable member 22 approaches or moves away from the clamping space 23, the movable member 22 can approach or move away from the first side plate 212.

[0059] Furthermore, the movable member 22 is slidingly matched with the second side plate 213 and / or the bottom plate 211, that is, only the sliding guide groove 214 is set on the bottom plate 211, and the sliding guide rail 223 is set on the movable member 22, so that the movable member 22 can only be slidingly matched with the bottom plate 211, or only the sliding guide groove 214 is set on the second side plate 213, and the sliding guide rail 223 is set on the movable member 22, so that the movable member 22 can only be slidingly matched with the second side plate 213, or the sliding guide groove 214 is set on both the bottom plate 211 and the second side plate 213, and the sliding guide rail 223 is set on the movable member 22, so that the movable member 22 can be slidingly matched with both the bottom plate 211 and the second side plate 213, thereby ensuring the reliability of matching.

[0060] The sliding guide groove 214 can be provided in a plurality, and the sliding guide rail 223 can also be provided in a plurality. The plurality of sliding guide grooves 214 and the plurality of sliding guide rails 223 are provided in a one-to-one correspondence, thereby ensuring the reliability of the sliding fit. Figure 4-Figure 5 As shown, the width of the sliding guide groove 214 located on the bottom plate 211 is set to be the smallest at the open mouth, that is, the width of the groove body gradually increases along the clamping direction, and the shape of the sliding guide rail 223 matches it, so that the sliding guide groove 214 can limit the displacement of the sliding guide rail 223 in the clamping direction, and then limit the displacement of the moving part 22 in the clamping direction, thereby ensuring the accuracy of the moving trajectory of the moving part 22.

[0061] In some embodiments, the surfaces where the mounting member 21 and / or the moving member 22 cooperate with the clamping block 11 are provided with a buffer layer 225, that is, the buffer layer 225 is provided only on the surface where the mounting member 21 cooperates with the clamping block 11, the buffer layer 225 is provided only on the surface where the moving member 22 cooperates with the clamping block 11, or the buffer layer 225 is provided on both the surface where the mounting member 21 cooperates with the clamping block 11 and the surface where the moving member 22 cooperates with the clamping block 11.
