DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.

[0021] The embodiment of the present application discloses a positioning guide for the installation of a new energy automobile battery pack, which refers to Figure 1 , comprising a guide pipe 1, a clamping assembly 2, and a driving assembly 3. The clamping assembly 2 and the driving assembly 3 are respectively arranged at both ends of the guide pipe 1, and the driving assembly 3 is used to drive the clamping assembly 2 to be fixed on the vehicle frame.

[0022] Referring to Figure 2 andFigure 3 The clamping assembly 2 comprises a base 21, a lifting block 22, a pull rod 23 and a pressing jaw 24. The base 21 is fixed at the end of the guide pipe 1. A through hole is formed in the middle of the base 21. The surface of the base 21 away from the guide pipe 1 is symmetrically provided with semicircular protrusions 211. The semicircular protrusions 211 are spaced from the edge of the lateral side of the base 21. A pin shaft 25 is symmetrically fixed between the two semicircular protrusions 211. The surface of the pin shaft 25 is symmetrically hinged with the pressing jaws 24. The surface of the pin shaft 25 between the two pressing jaws 24 is sleeved with a limiting ring 26. The two pressing jaws 24 are hinged with the pull rod 23. The ends of the two pull rods 23 are hinged on the lifting block 22.

[0023] The driving assembly 3 comprises a transmission shaft 31 and a rotating body 32. The rotating body 32 is rotationally arranged at the bottom end of the guide pipe 1. The transmission shaft 31 is fixed on the rotating body 32. The transmission shaft 31 is rotationally arranged in the through hole. The position of the transmission shaft 31 close to the top end is a threaded rod. The lifting block 22 is threadedly connected to the threaded rod.

[0024] An annular groove 321 is formed in the body of the rotating body 32 located in the guide pipe 1. Limiting bolts 4 are threadedly connected to the two sides of the guide pipe 1. The limiting bolts 4 extend into the annular groove 321.

[0025] In order to facilitate the assembly of the battery pack, the bottom end of the rotating body 32 is in the shape of a circular truncated cone. The edge of the bottom end of the rotating body 32 is provided with a rounded corner.

[0026] In order to facilitate the rotation of the rotating body 32, a slot hole 5 for passing a hexagonal wrench is formed in the bottom of the rotating body 32.

[0027] Referring to Figures 1-2 In order to avoid misoperation and cause the lifting block 22 to slip off, a anti-loosening nut 6 is threadedly screwed on the threaded rod on the surface of the transmission shaft 31.

[0028] The implementation principle of the positioning guide piece for the installation of the battery pack of the new energy vehicle according to the embodiment of the application is as follows:

[0029] In use, two positioning guide pieces are generally installed on the chassis of the vehicle to achieve the positioning effect. During installation, the rotating body 32 is first rotated to move the lifting block 22 upward. The lifting block 22 drives the pull rod 23 to move upward. The pull rod 23 pulls the pressing jaw 24 to be raised, so that the two pressing jaws 24 are retracted into the base 21. At this time, the clamping assembly 2 can be easily inserted into the corresponding hole of the vehicle chassis. The rotating body 32 is rotated again to move the lifting block 22 downward. The pressing jaw 24 is pushed by the pull rod 23 to be pressed downward to form a pull with the base 21, so that the positioning guide piece is locked on the vehicle chassis as a whole. Then the battery pack can pass through the positioning guide piece from below and accurately abut against the vehicle body. The bolts are screwed to complete the installation of the battery pack. The rotating body 32 is rotated again to loosen the pressing jaw 24, so that the positioning guide piece is separated.

[0030] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
