Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the sake of description, only the parts related to the present application rather than all the structures are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] The terms "first", "second", and "third" in this application are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, then the directional indications will change accordingly. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0027] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] The door handle provided by this application is applied to a vehicle door. The door handle includes: a first housing having a receiving groove; a second housing detachably mounted on the first housing and covering the notch of the receiving groove; and a sensing device disposed in the receiving groove. The sensing device includes a circuit board assembly and an insulating waterproof layer covering the circuit board assembly. In this way, the door handle can improve the production efficiency of the door handle and the reuse rate of materials during the production process while ensuring the waterproof performance.

[0029] The door handle is a commonly used automotive accessory for opening and closing the vehicle door. Door handles are usually located on the outside and inside of the vehicle door, enabling both passengers inside the vehicle and people outside to conveniently operate the door. Currently, the main types of automotive door handles are horizontal pull-type door handles and upward lift-type door handles. As a new type of door handle, the touch door handle has the advantage that it does not require operating a key for locking and unlocking, which is convenient for users and enhances convenience. It has increasingly gained the favor of automotive manufacturers and users. An induction device needs to be built into the touch door handle. However, since the door handle is generally exposed outside the vehicle body, the waterproof performance requirements for the touch door handle are quite high. Currently, most often, the induction device is encapsulated with glue through a potting process to meet the waterproof requirements of the door handle. However, the potting process is time-consuming and not conducive to the secondary utilization of the door handle housing, resulting in low production efficiency of the door handle and serious material waste.

[0030] Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of a vehicle provided by some embodiments of the present application. The vehicle 1000 may include, but is not limited to, a vehicle door 200 and a door handle 100 located on the vehicle door 200. Among them, the door handle 100 is a touch door handle, which can enable users to enter and exit the vehicle without using a key.

[0031] Please refer to in combination Figures 1-6 , Figure 1 which is a schematic structural diagram of a door handle provided by some embodiments of the present application, Figure 2 which is an exploded schematic diagram of a door handle provided by some embodiments of the present application, Figure 3 which is a schematic structural diagram of a first housing provided by some embodiments of the present application, Figure 4 which is Figure 3 a partial enlarged view of the first housing of Figure 5 at area A, provided by some embodiments of the present application, Figure 6 which is a schematic structural diagram of a second housing provided by some embodiments of the present application,

[0032] Furthermore, the sensing device 130 may include, but is not limited to, a circuit board assembly 131 and an insulating waterproof layer 132. The insulating waterproof layer 132 is wrapped around the circuit board assembly 131 to prevent the circuit board assembly 131 from short-circuiting and / or leaking electricity after the door handle 100 gets wet, thereby ensuring the waterproof performance and safety of the door handle 100. Among them, the circuit board assembly 131 can sense the situation where the user touches the door handle 100 to assist in confirming the user's intention to open or close the door, and then automatically unlock or lock the door lock after the key signal is matched.

[0033] It can be understood that after the sensing device 130 is placed in the accommodating groove 111 of the first housing 110, the door handle 100 provided by the present application can be assembled by covering the second housing 120. The production is convenient and fast, greatly improving the production efficiency of the door handle 100. Further, since the second housing 120 is detachably installed on the first housing 110, in the case where the sensing device 130 fails, a new sensing device 130 can be replaced by opening the second housing 120. In this way, the first housing 110 and the second housing 120 can be effectively reused, thereby avoiding waste of materials and improving the utilization rate of materials; at the same time, it is also convenient for subsequent diagnosis and maintenance of the door handle 100.

[0034] Optionally, the insulating waterproof layer 132 can be covered on the circuit board assembly 131 by means of low-pressure injection molding. The low-pressure injection molding process can provide excellent environmental protection for the circuit board assembly 131. The low-pressure injection molding process has a short molding time, enabling the insulating waterproof layer 132 to be quickly cured on the circuit board assembly 131. Therefore, compared with the relatively long molding time of the potting process, the production efficiency of the door handle 100 can be greatly improved.

[0035] Among them, the material of the insulating waterproof layer 132 can be a thermoplastic polyamide material. The thermoplastic polyamide material has excellent waterproof and electrical insulation properties, thereby enabling an effective insulating waterproof layer 132 to be formed. The thermoplastic polyamide material can be liquefied at low temperatures and injected into the mold under relatively small pressures, thus being able to better adapt to the low-pressure injection molding process.

[0036] In this embodiment, the thickness of the insulating waterproof layer 132 is greater than or equal to 1 mm and less than or equal to 3 mm. The thickness of the insulating waterproof layer 132 being greater than or equal to 1 mm enables the insulating waterproof layer 132 to have sufficient strength to ensure its insulation and waterproof performance. The thickness of the insulating waterproof layer 132 being less than or equal to 3 mm is to reduce the use of materials, reduce weight and cost. Specifically, the thickness of the insulating waterproof layer 132 can be 1 mm, 1.2 mm, 1.5 mm, 1.7 mm, 2 mm, 2.5 mm, 2.7 mm, 3 mm, etc.

[0037] Further, the sensing device 130 is provided with a limiting hole 133, and a limiting frustum 1111 is provided at the bottom of the accommodating groove 111. The limiting hole 133 is sleeved on the limiting frustum 1111 to position and install the sensing device 130 in the accommodating groove 111.

[0038] Further, both ends of the first housing 110 are respectively provided with a connecting portion 114 and a mounting portion 115. The connecting portion 114 is connected to the door lock mechanism inside the door 200, and the mounting portion 115 is mounted inside the door 200.

[0039] In this embodiment, the mounting portion 115 is further provided with a wire routing channel 1151. The wire routing channel 1151 is communicated with the accommodating groove 111, so that the wire harness of the circuit board assembly 131 can be led out through the wire routing channel 1151 to be connected to the controller inside the vehicle 1000. Several wire blocking structures 1152 are provided on at least one side of the wire routing channel 1151 to restrain the wire harness to stay inside the wire routing channel 1151.

[0040] Further, the first housing 110 is provided with a first snap structure 112 around the notch of the accommodating groove 111. A second snap structure 121 is provided on the side of the second housing 120 facing the first housing 111. By snap-connecting the first snap structure 112 and the second snap structure 121, the second housing 120 is detachably mounted on the first housing 111.

[0041] In this embodiment, the first snap structure 112 is a groove, and the second snap structure 121 is a protrusion. The second snap structure 121 can be elastically inserted into the first snap structure 112 to assemble and connect the first housing 110 and the second housing 120, so as to protect the sensing device 130. In other embodiments, the first snap structure 112 can be a protrusion, and the second snap structure 121 can be a groove.

[0042] Further, the first housing 110 is provided with first fastening holes 1112 on the groove walls at both ends of the accommodating groove 111. Both ends of the second housing 120 facing the first housing 110 are provided with second fastening holes 122. The second fastening holes 122 are connected to the first fastening holes 1112 through fasteners, so that the second housing 120 is fastened to the first housing 110.

[0043] In this embodiment, a limiting hook 113 is provided at one end of the first housing 110. A limiting hanging frame 123 is provided at one end of the second housing 120 facing the first housing 110. The limiting hook 113 can be hung on the limiting hanging frame 123 to prevent the second housing 120 from accidentally sliding off during the process of covering the first housing 110.

[0044] The door handle 100 provided by the present application is applied to a vehicle door 200. The door handle 100 includes: a first housing 110 having a receiving groove 111; a second housing 120 detachably mounted on the first housing 110 to cover the notch of the receiving groove 111; and a sensing device 130 disposed in the receiving groove 111. The sensing device 130 includes a circuit board assembly 131 and an insulating waterproof layer 132 covering the circuit board assembly 131. In this way, the door handle 100 can improve the production efficiency of the door handle 100 and the reuse rate of materials during the production process while ensuring the waterproof performance.

[0045] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall equally be included in the patent protection scope of the present application.
