It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

It should be noted that in this specification, like reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

In the description of the present embodiment, it should be noted that the terms "upper", "inner", "outer", etc. indicate the orientation or position relationship based on the figure or the orientation or position relationship that the utility model is usually placed when using, and are only for convenience of describing the utility model and simplifying the description, but do not indicate or imply that the device or element that is referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the utility model.

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The problem that the sensor fails due to the fact that a wire harness inside the door handle sensor is prone to breaking in the prior art is greatly disturbed in the using process of the door handle sensor. In addition, the problem of uneven gap between the locking button and the door handle shell also exists, which not only affects the appearance of the door handle, but also causes that accumulated water between the locking button and the door handle shell is not easy to discharge, and the sensitivity of the door handle sensor is affected.

The utility model provides a door handle sensor, as shown in fig. 1 and fig. 2, including antenna box cover 1, ground wire 2 and pencil 3, wherein, antenna box cover 1's afterbody has set up two strengthening ribs 11 on the width direction, and ground wire 2 is located between two strengthening ribs 11 to pencil 3 is located outside the region that two strengthening ribs 11 enclose. In this embodiment, one end of the antenna box cover close to the ground is taken as a tail, and as shown in fig. 1 and fig. 2, the width direction is a direction x in the drawing.

Because the detection shows that the wiring harness 3 inside the door handle sensor is easy to break due to the fact that the ground wire 2 is easy to generate relatively large lateral deviation in the use process to break the wiring harness 3, and the lateral deviation is the deviation of the ground wire in the width direction. Therefore, by arranging the two reinforcing ribs 11 at the tail part of the antenna box cover 1, the ground wire 2 can be effectively prevented from generating lateral deviation in the using process, and the ground wire 2 is further limited between the two reinforcing ribs 11, and the wire harness 3 is isolated outside the area formed by the two reinforcing ribs. Therefore, even if the ground wire 2 generates transverse deviation, the wire harness 3 is isolated by the two reinforcing ribs 11, so that the phenomenon that the wire harness 3 is cut by the ground wire 2 due to the fact that the wire harness 3 is in contact with the ground wire 2 can be avoided, the ground wire 2 can be prevented from being scratched or bent due to the deviation, the ground wire 2 is prevented from being damaged, and stable output of signals is guaranteed.

Specifically, as shown in fig. 3, 2 reinforcing ribs 11 are provided at the rear portion of the antenna box cover 1. And the top of the reinforcing rib 11 is lower than the top end surface of the ground wire 2 because the top of the ground wire is in contact with other parts of the door handle case, if the height of the reinforcing rib is higher than the ground wire, the contact of the ground wire is affected, and the top of the reinforcing rib is lower than the top end surface of the ground wire, and the ground wire can be prevented from being pulled out from between the two reinforcing ribs. In the present embodiment, the ribs 11 are triangular, but the ribs 11 may be other shapes such as long strips and rectangles, and the shape is not limited herein.

In addition, the distance between the two reinforcing ribs 11 is matched with the width of the ground wire 2, namely, the distance between the two reinforcing ribs 11 is slightly larger than the width of the ground wire 2, for example, the distance between the two reinforcing ribs 11 is 0.5mm to 2mm larger than the width of the ground wire 2, so that the ground wire can be better limited between the two limiting ribs, and the ground wire is prevented from generating larger transverse deviation, thereby not only ensuring that the wire harness is not split by the ground wire, but also reducing the damage of the ground wire in the transverse deviation process, and further ensuring the stable output of signals.

Further, in the embodiment, the reinforcing rib 11 and the antenna box cover 1 are integrally formed by injection molding, so that the processing technology becomes simple by direct injection molding on the basis of not changing the original design.

Fig. 4 is a partial enlarged view of the lock button on the door knob sensor antenna box cover. The antenna box cover 1 of the door handle sensor is provided with a locking button 12, and the periphery of the outer side of the locking button 12 is circumferentially provided with a plurality of limiting ribs 121. The locking button 12 and the reinforcing rib 11 are respectively located at both ends of the antenna box cover 1 in the longitudinal direction, and as shown in fig. 5, the locking button 12 is installed in the recess of the door handle housing 4, and the plurality of limiting ribs 121 can limit the relative displacement of the locking button 12 in the recess of the door handle housing 4. It is noted that the relative displacement here includes both the displacement in the length direction and the displacement in the width direction, and also includes the circumferential displacement of the lock button in the groove.

Through setting up spacing muscle, can not only make spacing muscle play the effect of installation direction when door handle casing and door handle sensor installation, can also make ponding flow in the water drainage tank in the door handle casing along the clearance between spacing muscle and the door handle casing, and then discharge, prevent that the door handle sensor from reducing its sensitivity because of ponding.

As shown in fig. 4 and fig. 6, in this embodiment, the limiting ribs are semi-cylindrical, but in other embodiments, the limiting ribs may also be rectangular, prismatic, and the like, and the locking button in this embodiment is rectangular, and the number of the limiting ribs is 6, and the limiting ribs are respectively located on the outer sides of the periphery of the locking button, wherein, two sides in the width direction, each side is provided with 2 limiting ribs, and two sides in the length direction, each side is provided with 1 limiting rib, but this cannot limit the number and the positions of the limiting ribs in the door handle sensor provided by the present invention, the number of the limiting ribs may be 4, 8, or more, and the positions thereof may also be additionally provided, as long as it is ensured that the locking button is limited to generate relative displacement in the groove, so neither limitation is made here.

The height of the limiting rib 121 is less than or equal to the height of the locking button 12, and the thickness of the limiting rib 121 should be less than the gap distance between the locking button 12 and the groove. Optionally, in order to make the assembly of the locking button and the door handle housing more beautiful, the height of the limiting rib 121 may be further set to be less than or equal to the depth of the groove on the door handle housing 4. In this embodiment, the direction perpendicular to the height direction of the lock button is the width direction and the length direction, wherein the thickness of the limiting rib disposed in the length direction is the dimension of the limiting rib in the length direction, and the thickness of the limiting rib in the width direction is the dimension of the limiting rib in the width direction.

Specifically, the clearance distance between the lock button 12 and the groove on the door handle 4 is approximately between 0.52mm and 0.53 mm. During implementation, as long as the thickness of guaranteeing spacing muscle is less than this numerical value just, but when the thickness undersize of spacing muscle, can have the clearance between the recess on spacing muscle and the door handle shell too big, influence the pleasing to the eye of product, and when the thickness of spacing muscle is too big, can lead to the clearance undersize, be unfavorable for locking ponding on the button and flow into the inside water drainage tank of door handle casing along this gap. Therefore optionally, in this embodiment, the thickness of the limiting rib 121 is about half of the gap distance between the locking button 12 and the groove on the door handle 4, and the limiting rib 121 and the door handle shell 4 are arranged in such a way, so that the appearance is not only considered, but also the limiting rib 121 and the door handle shell 4 are well conducted along the circumferential direction, when accumulated water is generated around the locking button, the accumulated water can flow in the gap, and then the accumulated water flows into the water drainage groove inside the door handle shell 4, and the accumulated water is removed.

Based on the same concept, the embodiment of the present invention also provides a door handle, including the door handle sensor as described above.

The embodiment of the utility model provides a door handle sensor, through set up two strengthening ribs 11 in the width direction of antenna box lid afterbody, can restrict ground wire 2 between two strengthening ribs 11 to and keep apart pencil 3 outside the region that two strengthening ribs formed, thereby prevent effectively that the ground wire from producing the lateral deviation in the use, avoid producing the risk that the pencil is split, and can also avoid the ground wire to be damaged because of the skew, and then guarantee the stable output of signal; and set up a plurality of spacing muscle in locking button's outside circumference, not only make spacing muscle play the effect of installation direction when door handle casing and door handle sensor installation, can also make ponding flow into the water drainage tank in the door handle casing along the clearance between spacing muscle and the door handle casing, and then discharge, prevent that door handle sensor from reducing its sensitivity because of ponding.
