[0038] The present utility model will be further described below with reference to the accompanying drawings

[0039] A detection device for a door handle, as shown in Figures 1-7As shown, it includes a handle skeleton 1 and a handle body 2. The handle skeleton 1 is provided with a handle hidden cavity 11 for installing the handle body 2. A driving module 12 and a push rod 13 are arranged on the handle skeleton 1. The driving module 12 drives the push rod 13 to slide on the handle skeleton 1 through a transmission component. The push rod 13 pushes the first swing arm 14 and the second swing arm 15 to rotate, thereby driving the handle body 2 to extend out of the handle hidden cavity 11. The handle body 2 is provided with an installation cavity 21. An outer cover assembly 3 is installed at the opening end of the installation cavity 21. The installation cavity 21 includes a first installation area 211 and a second installation area 212. An electromagnetic induction module 4 is installed in the first installation area 211. In this embodiment, the electromagnetic induction module 4 is set as an NFC induction module. A radar detection module 5 is installed in the second installation area 212. In this embodiment, the first installation area 211 is arranged close to the driving module 12, and the second installation area 212 is arranged far from the driving module 12. Moreover, the first installation area 211 occupies three-quarters of the space of the installation cavity 21, and the second installation area 212 occupies one-quarter of the space of the installation cavity 21. A positioning and installation structure extends from one side of the outer cover assembly 3 towards the second installation area 212. The radar detection module 5 is fixedly connected to the outer cover assembly 3 through the positioning and installation structure. The handle body 2 is provided with a plurality of retaining ribs 24 between the first installation area 211 and the second installation area 212. The retaining ribs 24 are used for retaining and positioning with the electromagnetic induction module 4.

A plurality of positioning ribs 25 are arranged in the installation cavity 21. The plurality of positioning ribs 25 are in positioning cooperation with the electromagnetic induction module 4. And the plurality of positioning ribs 25 define a heat dissipation space 26 on one side of the handle body 2 facing the installation cavity 21. The positioning ribs 25 are used for supporting and positioning the periphery of the electromagnetic induction module 4. At the same time, the heat dissipation space 26 formed by enclosing the positioning ribs 25 in the installation cavity 21 can quickly dissipate the heat generated by the operation of the electromagnetic induction module 4, preventing the electromagnetic induction module 4 from being damaged due to overheating.

The anti-detachment blocks 311 extend to the side of the clamping members 31 facing the radar detection module 5. The radar detection module 5 is clamped and anti-detached from the clamping members 31 through the anti-detachment blocks 311, so that the radar detection module 5 is clamped and positioned between multiple clamping members 31. And the side of the clamping member 31 away from the outer cover assembly 3 stops the end of the radar detection module 5 through the anti-detachment block 311, which can effectively prevent the radar detection module 5 from detaching from the outer cover assembly 3; reinforcing ribs 312 are provided on the outer wall of the clamping member 31 along the length direction. The addition of the reinforcing ribs 312 can improve the structural strength of the clamping member 31 in the length direction, thereby improving the anti-bending performance of the clamping member 31, and further improving the clamping stability of the clamping member 31 to the radar detection module 5. The thickness of the reinforcing ribs 312 gradually decreases from the side close to the outer cover assembly 3 to the side away from the outer cover assembly 3; a gap 310 is formed between adjacent clamping members 31. A rotation prevention portion 51 that is clamped and positioned with the gap 310 is provided on the outer wall of the radar detection module 5. The radar detection module 5 is rotationally prevented and cooperated with the clamping member 31 through the rotation prevention portion 51. When the radar detection module 5 is installed on the outer cover assembly 3, the rotation prevention portion 51 of the radar detection module 5 is clamped in the gap 310 between adjacent clamping members 31, which can prevent the radar detection module 5 from accidentally rotating and loosening after being installed on the outer cover assembly 3; the radar detection module 5 includes a radar probe 50. The outer cover assembly 3 is provided with a through hole 30 corresponding to the penetration of the radar probe 50. The through hole 30 is communicated with the second installation area 212. The radar probe 50 is inserted into the through hole 30, and the radar probe 50 is inserted and positioned with the through hole 30. The radar probe 50 can detect obstacles outside the handle body 2 through the through hole 30. At the same time, the through hole 30 can also restrain the radar probe 50 to improve the anti-shaking performance of the radar detection module 5.

[0041] As Figures 3-6 and Figures 8-10As shown in the figure, a locking structure is provided between the outer cover assembly 3 and the handle body 2. The outer cover assembly 3 is locked and fixed to the handle body 2 through the locking structure, so that the outer cover assembly 3 can be disassembled and assembled on the handle body 2 through the locking structure, improving the installation convenience of the electromagnetic induction module 4 and the radar detection module 5 in the installation cavity 21. The locking structure includes an L-shaped lock block 22 and a locking and matching part 321. The L-shaped lock block 22 is arranged on the handle body 2. A flange 32 is provided on one side of the outer cover assembly 3 facing the installation cavity 21, and the locking and matching part 321 is correspondingly arranged on the inner wall of the flange 32. The L-shaped lock block 22 is locked and matched with the corresponding locking and matching part 321. By using the locking force between the L-shaped lock block 22 and the locking and matching part 321, the outer cover assembly 3 can be detachably installed on the handle body 2. An elastic lock block 23 is arranged on the handle body 2. The elastic lock block 23 includes a resisting part 231 and a connecting part 232 with elastic deformation ability. The resisting part 231 is connected to the handle body 2 through the connecting part 232. The outer cover assembly 3 is provided with a stop block 33 corresponding to the resisting part 231. The resisting part 231 and the stop block 33 are in stop cooperation to limit the relative sliding of the L-shaped lock block 22 and the locking and matching part 321 in the unlocking direction. When the outer cover assembly 3 is installed on the handle body 2, the L-shaped lock block 22 and the locking and matching part 321 are locked with each other, and at the same time, the resisting part 231 of the elastic lock block 23 abuts against the stop block 33 of the outer cover assembly 3 to prevent the L-shaped lock block 22 from sliding relative to the locking and matching part 321 and causing the outer cover assembly 3 to fall off.

[0042] The basic working principle of the present utility model is as follows: The outer cover assembly 3 is detachably connected to the opening end of the installation cavity 21 of the handle body 2. During assembly, the electromagnetic induction module 4 is installed in the first installation area 211 of the installation cavity 21, and at the same time, the radar detection module 5 is fixedly connected to the outer cover assembly 3 through the positioning and installation structure. Then, the outer cover assembly 3 equipped with the radar detection module 5 is covered on the handle body 2, so that the radar detection module 5 is placed in the second installation area 212 of the handle body 2. The handle body 2 can be extended for use or retracted for storage in the handle hidden cavity 11 relative to the handle skeleton 1. The user can use an external communication device such as a mobile phone or a smart card to communicate and cooperate with the electromagnetic induction module 4 to unlock the door handle. At the same time, the door handle can also accurately detect obstacles near the vehicle door through the radar detection module 5. By arranging the radar detection module 5 and the electromagnetic induction module 4 in different areas of the installation cavity 21 of the handle body 2, the present utility model makes the door handle have multiple functions, and the spatial layout inside the handle body 2 is more reasonable. In addition, the radar detection module 5 is fixed on the outer cover assembly 3 by using the positioning and installation structure.
