DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "side" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The "inside", "inner side" or "interior" referred to in the present invention refers to the space enclosed by the device or element; "outside", "outside" or "exterior" refers to the space outside the device or element.

[0032] A key light-transmitting structure of a smart door lock in this embodiment, such as Figure 1 and 2 As shown, it includes a front panel 1, a decorative panel 2, a main circuit board 3, a light source 31, an FPC soft board 4 and a diffuser 5, wherein:

[0033] The main circuit board 3 is arranged in the front panel 1;

[0034] The light source 31 is disposed on the main circuit board 3;

[0035] The decorative plate 2 is covered on the front panel 1, and a keyboard portion 21 is provided on the decorative plate 2. The keyboard portion 21 is provided with at least one light-transmissive key 211;

[0036] The FPC soft board 4 is installed on the inner wall of the decorative board 2 and connected to the main circuit board 3; a plurality of soft board light-transmitting holes 41 are provided on the FPC soft board 4, and the soft board light-transmitting holes 41 correspond to the positions of the light source 31 and the button 211, and the button 211 is offset toward the top direction of the decorative board 2 relative to the soft board light-transmitting holes 41;

[0037] The light diffuser 5 is disposed between the light source 31 and the FPC board 4 .

[0038] The present invention is provided with a diffuser plate 5 between the FPC soft board 4 and the decorative board 2 for diffusing light. When the light source 31 on the back panel is turned on, the light from the light source 31 passes through the soft board light-transmitting hole 41 on the FPC soft board 4 and irradiates the diffuser plate 5. After the light is diffused by the diffuser plate 5, the path of the light becomes irregular, thus avoiding the light from directly passing through the button 211 and irradiating the outside of the smart door lock. This not only avoids the problem of glare when the user looks directly at the keyboard of the smart door lock, but also makes the keyboard backlight more divergent and softer, and the viewing angle of the backlight is larger.

[0039] The traditional smart door lock adopts the setting of the light source 31, the FPC soft board 4 and the key 211 on the same horizontal line, so the light is emitted horizontally through the key 211. At this time, when the user looks at the keyboard of the smart door lock from top to bottom, since most of the backlight of the keyboard is horizontal, the user's line of sight needs to be close to perpendicular to the keyboard to see the backlight on the keyboard, which results in a very poor user experience. The present invention offsets the key 211 on the decorative panel 2 upward relative to the light transmission hole 41 of the soft board, and cooperates with the diffuser plate 5, so that the light can be offset upward by a certain angle when emitted from the key 211, so that the user can also see the backlight on the keyboard when looking at the keyboard from top to bottom, which is more in line with the usage habits of the smart lock and provides a better user experience.

[0040] The key 211 is offset by 0.7mm-0.8mm relative to the soft board light-transmitting hole 41 toward the top of the decorative board 2. According to the test, the key 211 is offset by 0.7mm-0.8mm relative to the soft board light-transmitting hole 41 toward the top of the decorative board 2, and the light transmission effect of the key 211 is the best, and the user can more easily see the backlight of the key 211.

[0041] The outer surface of the front panel 1 is recessed with an installation groove 11, the bottom of the installation groove 11 is lower than the outer surface of the front panel 1, and protrudes relative to the inner wall of the front panel 1 to form a reinforcement portion 12, and the main circuit board 3 is installed on the side wall of the reinforcement portion 12 away from the outer wall of the front panel 1.

[0042] In order to make the light emitted by the light source 31 on the main circuit board 3 pass smoothly through the keyboard area on the decorative panel 2, the traditional smart door lock usually adopts a hollowing setting at the position corresponding to the FPC soft board 4 in the upper half of the front panel 1, but this will reduce the overall strength of the front panel 1 and make it easy to deform. The present invention sets a reinforcing part 12 in the upper half of the frame part, which can greatly improve the strength of the front panel 1, making it less likely to deform and the product quality is better; in addition, a plurality of front panel light-transmitting holes 121 are set on the reinforcing part 12, and the light-transmitting holes also correspond to the position of the light source 31, so that the light emitted by the light source 31 can pass through the front panel light-transmitting holes 121 and the FPC soft board light-transmitting holes 41 to irradiate the diffuser 5, and finally make the keys 211 on the keyboard emit backlight; the present invention can greatly increase the strength of the front panel 1 without affecting the keyboard backlight, and the product quality is greatly improved.

[0043] It also includes a pressure pad 6, which is installed in the installation groove 11 and is provided with a plurality of pressure pad light-transmitting holes 61 corresponding to the positions of the soft board light-transmitting holes 41; the FPC soft board 4 is bonded to the inner wall of the keyboard part 21 through the diffuser plate 5; the pressure pad 6 is supported on the diffuser plate 5, so that the FPC soft board 4 is tightly attached to the inner wall of the keyboard part 21.

[0044] A pressing pad 6 is arranged between the FPC soft board 4 and the reinforcing part 12 so that the FPC soft board 4 can be pressed against the keyboard part 21 of the decorative panel 2, so that the FPC soft board 4 and the astigmatism can be tightly attached to the key 211, and the blank touch point caused by the gap between the FPC soft board 4 and the keyboard part 21 of the decorative panel 2 can be prevented, so that the key 211 is more sensitive to touch; in addition, the pressing pad 6 can also support the decorative panel 2, so that the key 211 of the decorative panel 2 has a better texture when in use, and avoids the hollow feeling of the key 211 when in use due to the keyboard part 21 being suspended in the air.

[0045] The reinforcing portion 12 is provided with a recessed groove 13 on the surface of the main circuit board 3, and a plurality of convex columns 14 corresponding to the positions of the light-transmitting holes 121 of the front panel protrude from the bottom surface of the recessed groove 13. The convex columns 14 are lower than the surface of the reinforcing portion 12 close to the main circuit board 3, and the light-transmitting holes 121 of the front panel pass through the convex columns 14.

[0046] The convex column 14 can play the role of guiding light, preventing the light from diffusing in other directions and making the light more concentrated.

[0047] A first threading hole 122 is provided at one end of the reinforcing portion 12, a second threading hole 32 corresponding to the first threading hole 122 is provided at the main circuit board 3, an FPC connector 33 is provided at the main circuit board 3, and a pin 42 is provided at one end of the FPC soft board 4 corresponding to the first threading hole 122, and the pin 42 passes through the first threading hole 122 and the second threading hole 32 to be connected to the FPC connector 33.

[0048] Since the main circuit board 3 and the FPC soft board 4 are separated by the reinforcement portion 12 of the front panel 1, in order to enable the FPC soft board 4 to be connected to the main circuit board 3, a first threading hole 122 and a second threading hole 32 are respectively provided on the reinforcement portion 12 and the main circuit board 3. This is to enable the pin 42 at the lower end of the FPC soft board 4 to be connected to the main circuit board 3. In addition, since a light source 31 is provided on the front side of the main circuit board 3, the FPC connector 33 is provided on the back side of the main circuit board 3 to reduce the volume of the main circuit board 3, and at the same time, it will not occupy the space between the main circuit board 3 and the reinforcement portion 12, making the main circuit board 3 and the reinforcement portion 12 more compact.

[0049] The pin 42 is formed by bending and extending from the FPC soft board 4, and the pin 42 has a connecting portion 421 and a contact portion 422; the connecting portion 421 is formed by bending and extending from the main body of the FPC soft board 4, and the connecting portion 421 passes through the first threading hole 122 and the second threading hole 32; the contact portion 422 is formed by bending and extending from one end of the connecting portion 421 toward the direction of the FPC connector 33, and is connected to the FPC connector 33.

[0050] The FPC soft board 4 has a certain degree of flexibility, and such a configuration allows the pin 42 to pass through the first threading hole 122 and the second threading hole 32 to connect with the FPC connector 33 .

[0051] The surface of the diffuser plate 5 is coated with an adhesive, specifically, the adhesive is a double-sided adhesive, the FPC soft board 4 is bonded to the diffuser plate 5 through the adhesive, and is adhered to the inner wall of the keyboard part 21 through the adhesive that exposes the light-transmitting hole 41 of the soft board; the pressing pad 6 covers the entire surface of the FPC soft board 4, which is made of rubber, and the pressing pad 6 is provided with a third threading hole 62 corresponding to the position of the first threading hole 122, and the pin 42 passes through the third threading hole 62, the first threading hole 122 and the second threading hole 32 in sequence to connect with the FPC connector 33;

[0052] The back of the keyboard part 21 is provided with a first positioning column 212, and there are at least two first positioning columns 212, and the positioning columns are arranged in the longitudinal direction; the diffuser plate 5 is provided with a first positioning hole 51, and the FPC soft board 4 is provided with a second positioning hole 43, and the positions of the first positioning hole 51 and the second positioning hole 43 correspond to the positions of the first positioning column 212 respectively;

[0053] The first positioning column 212 is arranged on the decorative panel 2 to facilitate the installation of the diffuser plate 5 and the FPC soft board 4 on the decorative panel 2, thereby improving the assembly efficiency of the door lock. In addition, the first positioning column 212 also limits the FPC soft board 4 and the diffuser plate 5. After the assembly is completed, the FPC soft board 4 and the diffuser plate 5 will not move, so that the position of the button 211 on the FPC soft board 4 corresponds to the position of the button 211 on the decorative panel 2, thereby preventing the FPC soft board 4 from being offset and causing the button 211 to be disordered.

[0054] The front panel 1 is provided with a second positioning column 15, and the second positioning column 15 is located on the central axis of the front panel 1;

[0055] The second positioning column 15 is used to connect with the rear panel. Traditional smart door locks usually set two second positioning columns 15 on both sides of the upper end of the installation part, which not only increases the production cost, but also requires the two second positioning columns 15 to be aligned at the same time for installation, and the installation process is very difficult. The present invention innovatively sets the second positioning column 15 at the center axis position of the front panel 1, and reduces the number of second positioning columns 15 to 1. In this way, the difficulty of installation can be reduced while ensuring that the front panel 1 and the rear panel can be positioned and connected, from the need to align two second positioning columns 15 to only need to align one positioning column, and the installation efficiency of the smart door lock is higher.

[0056] The light diffuser plate 5 is made of PET.

[0057] Since PET material has high light transmittance, the use of PET material for the diffuser plate 5 can reduce light loss when passing through the diffuser plate 5. In this way, there is no need to increase the power of the light source 31 due to the addition of the diffuser plate 5, and the cost of the smart door lock can be better controlled.

[0058] A smart door lock comprises the above-mentioned button light-transmitting structure of a smart door lock and a base plate 7, wherein the base plate 7 and the front panel 1 form a receiving cavity, and the button 211 light-transmitting structure of the smart door lock is installed in the receiving cavity.

[0059] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific embodiments of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
