[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2In the figure, a double shell for protecting the circuit of an electric vehicle sensor includes a protection shell 1, which is used to protect the circuit of the electric vehicle sensor. The protection shell 1 includes a shell 101 and a shell 102. The shell 101 and the shell 102 are equal in shape and size. A wave plate 103 is installed between the shell 101 and the shell 102; a connecting component 2 is used to connect the shell 102 and the wave plate 103. A plurality of connecting components 2 distributed at equal distances are installed between the shell 102 and the wave plate 103.

[0023] See also Figure 2 The connection between the corrugated plate 103 and the shell 101 is fixed welding, and the corrugated plate 103 can enhance the anti-deformation performance of the protective shell 1.

[0024] The working principle of the electric vehicle sensor circuit protection shell with good deformation resistance: the protective baffle made of the protective shell 1 protects the electric vehicle sensor circuit, and the wave plate 103 is located between the shell 101 and the shell 2 102, which can effectively enhance the deformation resistance of the protective shell 1, so that the protective shell 1 has a better protection effect on the electric vehicle sensor circuit.

[0025] Embodiment 2

[0026] See also Figure 2 This embodiment further explains the first embodiment. The connecting component 2 includes a connecting column 201. The cross-sectional shape of the connecting column 201 is circular, and the connecting column 201 is located on the side of the wave plate 103 close to the shell 2 102. The connecting column 201 and the wave plate 103 are an integrally formed structure. The outer side of the connecting column 201 is movably sleeved with an arc sleeve 202, and the cross-sectional inner diameter length of the arc sleeve 202 is greater than half the circumference of the connecting column 201.

[0027] See also Figure 3 The connection between the arc sleeve 202 and the connecting column 201 is a fixed connection. The upper end of the arc sleeve 202 is fixedly connected with a blocking column 203, which can prevent the shell 2 102 from moving downward. The blocking column 203 and the shell 2 102 are fixedly connected, and the upper end of the connecting column 201 is movably abutted against the lower end of the blocking column 203.

[0028] In this embodiment: when assembling the protective shell 1, the personnel first weld the guide tube 3 to the shell 1, then cover the wave plate 103 on the upper side of the guide tube 3, and then weld the wave plate 103 to the shell 1 101, and then place the shell 1 101 and the wave plate 103 vertically, and put the multiple arc sleeves 202 on the shell 2 102 correspondingly on the outside of the multiple connecting columns 201, when the shell 2 102 moves down to the lower end of the blocking column 203 and abuts against the upper end of the connecting column 201, the shell 1 101 and the shell 2 102 are in an aligned state, and at this time, the shell 2 102 and the wave plate 103 are welded, which can not only enhance the connection strength between the shell 2 102 and the wave plate 103, but also help to reduce the difficulty of assembling the protective shell 1.
