[0036] like Figure 1As shown, the present application provides a hidden door handle 100 for a car door. When not in use, the hidden door handle 100 is hidden inside the car door and forms a whole with the car door, so that there is no protrusion on the surface of the car door. When the hidden door handle 100 for the car door needs to be used, the hidden door handle 100 for the car door can be extended and exposed on the car door by triggering.
[0037] Specifically, please refer to Figures 2 to 6 The hidden door handle 100 for an automobile door comprises a handle frame 10, a circuit board 20, a sensor 30 and a limiting structure 40. The handle frame 10 has a cavity 11 inside, the circuit board 20 is arranged in the cavity 11, the circuit board 20 is arranged in the cavity 11 and has an inner side surface 21 and an outer side surface 22 arranged opposite to each other, the sensor 30 is electrically connected to the circuit board 20 and has a first sensing area 31 and a second sensing area 32, the first sensing area 31 is arranged on the inner side surface 21 and is used to control the unlocking of the automobile door, the second sensing area 32 is arranged on the outer side surface 22 and is used to control the hiding and unfolding of the handle frame 10 relative to the automobile door, and the unlocking and locking of the entire vehicle; wherein, the above-mentioned limiting structure 40 is arranged on one of the inner wall of the cavity 11 and the circuit board 20, and a matching portion 50 is opened on the other, the limiting structure 40 is located at a position outside the axisymmetry of the circuit board 20, and can be limitedly matched with the matching portion 50. In this way, the matching characteristics of the limiting structure 40 and the matching part 50 can be used to realize the positioning of the circuit board 20 during the assembly process, thereby preventing the circuit board 20 from being installed incorrectly or reversely. At the same time, the present application forms a responsive sensing area on both sides of the circuit board 20 through the sensor 30, so that the door can be unlocked and locked without pulling the handle or adding components such as micro switches, which has a better door opening and closing experience and a sense of technology.
[0038] It should be explained that, with the inside and outside of the car as reference, the inner side 21 of the circuit board 20 is the side of the circuit board 20 facing the inside of the car. The outer side of the circuit board 20 is the side of the circuit board 20 facing the outside of the car. When the hidden door handle 100 of the car door is used, the handle frame 10 can be extended relative to the car door (i.e., the handle frame 10 is unfolded) and the whole car is unlocked by triggering the second sensing area 32, and then the car door is unlocked by triggering the first sensing area 31 on the inside.
[0039] Please continue to refer to Figure 3 The handle frame 10 includes a main body 10a and a cover body 10b. A groove is formed on the main body 10a. The cover body 10b is covered in the groove, so as to form a cavity 11 together with the main body 10a.
[0040] Preferably, the cover 10b and the main body 10a can be connected in a detachable manner, wherein the detachable manner includes a snap connection, a screw connection, and the like.
[0041] In one embodiment, if Figure 5 and Figure 6 As shown, the shape of the circuit board 20 is set to be rectangular, oval, etc. In this embodiment, the circuit board is set to be rectangular.
[0042] In one embodiment, the sensor 30 may be a capacitive sensor, a pressure sensor, etc. In this embodiment, the sensor 30 is configured as a capacitive sensor. In this way, the opening feel of the car door can be optimized (without pulling the outer handle), the load of the outer handle can be reduced, and the reliability of the outer handle can be improved.
[0043] Furthermore, if Figure 6 As shown, the number of the second sensing areas 32 can be set to multiple, and the multiple second sensing areas 32 are arranged on the circuit board 20 at intervals along the length direction x of the car. In this way, multiple triggering areas can be formed on the handle frame 10 to improve the triggering effect and stability.
[0044] like Figure 2 and Figure 4 As shown, the limiting structure 40 includes a first limiting member 41 , and the matching portion 50 includes a limiting hole 51 . One of the first limiting member 41 and the limiting hole 51 is disposed on the inner wall 11 a of the cavity 11 , and the other is located on the circuit board 20 .
[0045] In other words, the first stopper 41 may be disposed on the inner wall 11a of the cavity 11, and the stopper hole 51 may be provided on the circuit board 20; or the first stopper 41 may be disposed on the circuit board 20, and the stopper hole 51 may be provided on the inner wall 11a of the cavity 11. Exemplarily, the first stopper 41 may be disposed on the inner wall 11a of the cavity 11, and the stopper hole 51 may be provided on the circuit board 20.
[0046] Furthermore, the first limiting member 41 and the handle frame 10 are integrally formed, thereby improving the structural strength of the first limiting member 41 .
[0047] Here, the first stopper 41 is configured as a column protruding from the inner wall 11a. Specifically, the first stopper 41 is configured at the bottom of the cavity 11, and the first stopper 41 extends along the direction of the cover 10b.
[0048] like Figure 2 and Figure 4 As shown, the limiting structure 40 further includes a second limiting member 42 , and the matching portion 50 further includes a limiting groove 52 . One of the second limiting member 42 and the limiting groove 52 is disposed on the inner wall 11 a of the cavity 11 , and the other is located on the circuit board 20 .
[0049] In other words, the second stopper 42 may be disposed on the inner wall 11a of the cavity 11, and the stopper groove 52 may be provided on the circuit board 20; or the second stopper 42 may be disposed on the circuit board 20, and the stopper groove 52 may be provided on the inner wall 11a of the cavity 11. Exemplarily, the second stopper 42 is disposed on the circuit board 20, and the stopper groove 52 is provided on the inner wall 11a of the cavity 11.
[0050] As preferably, Figure 2 As shown, the first stopper 41 is provided on the inner wall 11a of the cavity 11 and arranged in the cavity 11 along the first direction x; the second stopper 42 is provided on the circuit board 20 and arranged on the circuit board 20 along the second direction y; wherein the first direction x and the second direction y are arranged at an angle. In this way, the circuit board 20 can be stopped from different directions, effectively providing stability for assembly of the circuit board 20.
[0051] Here, the first direction y is configured as the width direction of the car, and the second direction x is configured as the length direction of the car. At this time, the first direction y is perpendicular to the second direction x. Of course, the first direction y and the second direction x can also be set at 80 degrees, 85 degrees, 95 degrees, etc.
[0052] Furthermore, the second stopper 42 and the circuit board 20 are configured to be integrally formed. In this way, during the molding process of the circuit board 20, the second stopper 42 can be molded together, which makes the processing more convenient and the structural strength higher.
[0053] Furthermore, if Figure 2 and Figure 3 As shown, the limiting groove 52 has an opening 521, and the second limiting member 42 is inserted into the limiting groove 52 through the opening 521; wherein, a flared opening 522 is provided at the opening 521, and the flared opening 522 is connected to the opening 521. In this way, through the setting of the flared opening 522, the second limiting member 42 can be guided to be quickly inserted into the limiting groove, thereby improving assembly efficiency.
[0054] like Figure 2 and Figure 3 As shown, the limiting structure 40 also includes a third limiting member 43, which is disposed in the cavity 11 and protrudes from the inner wall 11a of the cavity 11 along the third direction z and abuts against the circuit board 20; wherein the third direction z is perpendicular to the plane formed by the first direction y and the second direction x. In this way, in combination with the first limiting member 41 and the second limiting member 42, the circuit board 20 can be limited in three different directions, making the installation of the circuit board 20 more stable. At the same time, adding the third limiting member 43 as a positioning mark can further prevent the circuit board 20 from being installed incorrectly or reversely.
[0055] Preferably, the third stopper 43 is configured as a protrusion, and the third stopper 43 and the inner wall 11a of the cavity 11 are set as an integral structure. In this way, during the molding process of the handle frame 10, the third stopper 43 can be molded together, which is more convenient to process and has higher structural strength.
[0056] In one embodiment, if Figure 2 and Figure 7 As shown, the hidden door handle 100 for the automobile door further includes a lead 60, and one end of the circuit board 20 has an interface 23, and the lead 60 is connected to the interface 23, so as to realize the power supply of the circuit board 20. It can be understood that the interface 23 is provided at one end of the circuit board 20, so that the lead 60 is only located at one end of the circuit board 20, which is conducive to the neat arrangement of the lead 60.
[0057] The present application also provides a car door, comprising the hidden door handle 100 of the car door in any one of the above embodiments.
[0058] The present application also provides a car, comprising the car door in any one of the above embodiments.
[0059] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
