[0030] Embodiment one
[0031] The present embodiment is a first embodiment of a hidden door handle, as shown in Figure 1 , Figure 2 and Figure 4 , comprising a handle cover 100, a handle base 200, a sensor 300, a first silica gel sheet 400 and a second silica gel sheet 500, the handle cover 100 is detachably connected with the handle base 200, the sensor 300 is arranged on the handle base 200, the first silica gel sheet 400 is arranged on the sensor 300, the second silica gel sheet 500 is arranged on the handle cover 100, and the first silica gel sheet 400 and the second silica gel sheet 500 abut.
[0032] As shown in Figure 3 , the first silica gel sheet 400 is provided with a first matching structure 410, as shown in Figure 5As shown, the second silica gel sheet 500 is provided with a second matching structure 510, such as Figure 6 As shown, the first matching structure 410 is connected with the second matching structure 510, which can be detachable connection such as plug-in, buckle connection, etc., so that the first matching structure 410 can be separated from the second matching structure 510, that is, the handle cover 100 and the handle base 200 can be separated, thereby facilitating the maintenance or replacement of the handle interior. By providing the first matching structure 410 and the second matching structure 510, the connection relationship between the first silica gel sheet 400 and the second silica gel sheet 500 is enhanced, and the sealing effect of the first silica gel sheet 400 and the second silica gel sheet 500 is better.
[0033] As shown in Figure 6 As shown, the first silica gel sheet 400 and / or the second silica gel sheet 500 has a drainage slope structure 600 at the top, that is, the top surface of the first silica gel sheet 400 and / or the second silica gel sheet 500 is inclined, and the inclination direction is gradually inclined downward along the length direction of the silica gel sheet. In the present embodiment, the inclination angle is preferably 3.5°. By providing the drainage slope structure 600, when water enters from the outside, it can be quickly drained through the drainage slope structure 600, and water accumulation will not be formed, so that the sensor function of the sensor 300 will not be easily failed under harsh working conditions such as high temperature and high humidity.
[0034] The working principle of the hidden door handle of the present embodiment is as follows:
[0035] As shown in Figure 2 As shown, the first silica gel sheet 400 is fixedly connected to the area required to be waterproof by the sensor 300, and in the present embodiment, the fixed connection can be a waterproof fixed connection structure such as bonding. Figure 4 As shown, the second silica gel sheet 500 is fixedly connected to the handle cover 100, and in the present embodiment, the fixed connection can be a waterproof fixed connection structure such as bonding, and the second silica gel sheet 500 is located at a position corresponding to the first silica gel sheet 400. As shown in Figure 1As shown, when the handle cover 100 is assembled to the handle base 200, the first silica gel sheet 400 abuts against the second silica gel sheet 500, and the first matching structure 410 is connected with the second matching structure 510. The sealing relationship of the first silica gel sheet 400 and the second silica gel sheet 500 is used to replace the sealing relationship of the silica gel sheet and the plastic cover commonly used in the industry at present, and the waterproof sealing effect is better. When water accidentally enters from the outside, it is drained through the drainage slope structure 600, and water accumulation is not formed. The abutment of the first silica gel sheet 400 and the second silica gel sheet 500, the fixed connection of the first silica gel sheet 400 with the sensor 300, and the fixed connection of the second silica gel sheet 500 with the handle cover 100 facilitate the assembly and disassembly of the handle cover 100 on the handle base 200, thereby facilitating the maintenance of the handle interior. By splitting the traditional whole silica gel sheet into the first silica gel sheet 400 and the second silica gel sheet 500, and using the abutment between the first silica gel sheet 400 and the second silica gel sheet 500 for sealing, the assembly is facilitated, the sealing effect is better, and the sensor function is not prone to failure under harsh working conditions such as high temperature and high humidity.
[0036] Embodiment Two
[0037] This embodiment is a second embodiment of a hidden door handle, which is similar to Embodiment One, except that Figure 4 As shown, the handle cover 100 is provided with a first side sliding buckle 110, and Figure 2 As shown, the handle base 200 is provided with a second side sliding buckle 210, and the first side sliding buckle 110 is buckled connected with the second side sliding buckle 210, and Figure 3 As shown, the first matching structure 410 is provided as a guide groove, and Figure 5 As shown, the second matching structure 510 is provided as a guide plug, and Figure 6 As shown, the guide plug is inserted in the guide groove; the insertion direction of the guide plug is consistent with the side sliding direction of the first side sliding buckle 110, and is preferably perpendicular to the thickness direction of the silica gel sheet. The assembly and disassembly mode between the handle cover 100 and the handle base 200 is set as side sliding buckling, which facilitates the assembly and disassembly of the handle cover 100 on the handle base 200. At the same time, the guide plug and the guide groove are provided, and when the handle is installed by side sliding buckling, the guide plug is inserted into the guide groove, which facilitates the sealing connection between the first silica gel sheet 400 and the second silica gel sheet 500 and the positioning of the handle assembly.
[0038] The first silica gel sheet 400 and the second silica gel sheet 500 are filled with a grease structure. By providing the grease structure, the sealing effect is enhanced by using oil sealing. At the same time, the grease structure is used for lubrication during installation, which also facilitates the sliding of the second matching structure 510 into the first matching structure 410.
[0039] Embodiment Three
[0040] The third embodiment of the hidden door handle is similar to the second embodiment, but different in that, as shown in Figures 2 to 6 The second silica gel sheet 500 abuts against the sensor 300, that is, as shown in Figure 3 The first silica gel sheet 400 is shaped as a U-shaped groove. When the second silica gel sheet 500 is connected to the first silica gel sheet 400, the thickness at the first matching structure 410 is the thickness of the second silica gel sheet 500. The abutment of the second silica gel sheet 500 against the sensor 300 can reduce the total thickness of the first silica gel sheet 400 and the second silica gel sheet 500.
[0041] As shown in Figure 3 and Figure 5 The third matching structure 411 is arranged on both sides of the guide groove, and the fourth matching structure 511 is arranged on both sides of the guide block. The third matching structure 411 and the fourth matching structure 511 are connected. On the basis of using the guide block and the guide groove to position the first silica gel sheet 400 and the second silica gel sheet 500, the third matching structure 411 and the fourth matching structure 511 are arranged to further position the connection of the first silica gel sheet 400 and the second silica gel sheet 500, and to enhance the sealing connection between the first silica gel sheet and the second silica gel sheet.
[0042] As shown in Figure 5 The fourth matching structure 511 is shaped as a step, and as shown in Figure 3 The third matching structure 411 is shaped as a step groove matched with the step. As shown in Figure 6 The step and the step groove can enhance the sealing connection between the first silica gel sheet and the second silica gel sheet.
[0043] As shown in Figure 5 The thickness of the fourth matching structure 511 is not greater than the height of the fourth matching structure 511. This is conducive to the extrusion deformation of the fourth matching structure 511, and facilitates the side-sliding movement of the fourth matching structure 511 into the third matching structure 411. When the fourth matching structure 511 is shaped as a protrusion, the thickness of the protrusion is not greater than the height of the protrusion. When the fourth matching structure 511 is shaped as a step, the thickness of each step is not greater than the height of the step.
[0044] In this embodiment, in order to enhance the sealing effect on the basis of reducing the total thickness of the silica gel sheet, as shown in Figure 6As shown, two steps are provided in total, the total thickness of the first silica gel sheet 400 is 1.3mm, the thickness of the two steps is 0.4mm, the total thickness of the second silica gel sheet 500 is 1.8mm, and the height of the steps is 0.75mm. After the steps enter the step grooves, the steps will be compressed in the thickness direction, and the thickness of the steps is set to be not greater than the height of the steps, which is beneficial to the extrusion deformation of the steps and facilitates the side sliding movement of the steps into the step grooves.
[0045] As shown, Figure 6 The guide insertion block is in interference fit with the guide groove, and the fourth matching structure 511 is in clearance fit with the third matching structure 411. Through the clearance fit between the steps and the step grooves, the steps are facilitated to slide into the step grooves, and at the same time, the guide insertion block is in interference fit with the guide groove, so that the first silica gel sheet 400 and the second silica gel sheet 500 are sealed and connected, and balance is formed in the aspects of providing guidance, forming a seal, and assembly adaptability.
[0046] In the embodiment, since the first silica gel sheet 400 needs to play a certain guiding role during installation, a higher Shore hardness needs to be used to improve the deformation resistance, and 40-50A is selected. The second silica gel sheet 500 needs to be compressed during installation, and the Shore hardness is selected to be 20-30A.
