[0018] like Figure 1 - Figure 4The invention shown is an airtight and waterproof injection-molded housing for an automotive sensor, comprising a housing 1, an end shell 2 at one end of the housing 1, a sealing cap 3 installed on the inner wall of the end shell 2, and a reinforcing member on one end face of the sealing cap 3, the reinforcing member comprising: a reinforcing ring 4, fixedly located on one end face of the sealing cap 3, a plurality of connecting strips 5 fixedly fixed on the outer wall of the reinforcing ring 4, and a vertical strip 6 fixedly connected to one end of each connecting strip 5; and an outer ring 7, located on the outer wall of the vertical strips 6, the plurality of vertical strips 6 being fixedly connected to the outer ring 7.

[0019] In this embodiment, as Figure 1 - Figure 2 As shown, the outer shell 1, the end shell 2, and the sealing cover 3 are all integrally injection molded. The outer diameter of the end shell 2 is larger than the outer diameter of the outer shell 1, so that the outer shell 1, the end shell 2, and the sealing cover 3 can all wrap and protect the automotive sensor.

[0020] In this embodiment, as Figure 2 - Figure 3 As shown, multiple connecting strips 5 and multiple vertical strips 6 are arranged in a circular pattern. The vertical strips 6 and connecting strips 5 are integrally molded by injection molding, so that the connecting strips 5 and vertical strips 6 can form a circumferential reinforcement, resulting in a better reinforcement effect.

[0021] In this embodiment, as Figure 2 As shown, the outer ring 7 and the end shell 2 are integrally formed by injection molding. The vertical cross-section of the outer ring 7 is circular to facilitate a stable connection between the outer ring 7 and the end shell 2 and increase the edge strength of the end shell 2.

[0022] This airtight and waterproof automotive sensor injection-molded housing, when in use, is airtight and waterproof by the outer shell 1 and the end shell 2 wrapping around the outside of the automotive sensor. At the same time, the end shell 2 supports the sealing cover 3, which provides airtight protection for the end of the automotive sensor. The sealing cover 3 supports the reinforcing ring 4, which supports multiple connecting strips 5. The connecting strips 5 support vertical strips 6, which provide reinforcement to the outer ring 7. Furthermore, the end shell 2 and the outer ring 7 are integrally molded by injection molding, which greatly improves the compressive deformation strength. In this way, the connection between the sealing cover 3 and the end shell 2 is prevented from deformation and cracking, and the waterproofing effect is better.

[0023] In this embodiment, as Figure 4 As shown, the outer wall of the outer ring 7 is provided with multiple strips 8, and a support strip 9 is fixed to one end of each strip 8. A support ring 10 is installed at one end of the support strip 9. The support ring 10 and the support strip 9 are integrally formed with the outer shell 1 by injection molding. The multiple strips 8 are integrally formed with the outer ring 7 by injection molding, and the multiple strips 8 are arranged in a circumferentially equidistant distribution.

[0024] When this technology is in use, when the external support bar 9 is compressed, the outer ring 7 supports the bar body 8, the bar body 8 supports the support bar 9, and the support bar 9 supports the support ring 10. In this way, the support bar 9, the bar body 8, and the support ring 10 all provide a wrapping reinforcement support for the outer wall of the outer shell 1, and the left end of the outer shell 1 is prevented from deforming and cracking at the connection with the car sensor.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
