[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] The following describes in detail, with reference to the accompanying drawings, the specific structure of a button module provided by this utility model and its corresponding technical effects.

[0033] This utility model embodiment provides a button module that can be used in some electronic devices that require password input, such as electronic door locks.

[0034] Please refer to Figures 1-4 The present invention provides a button module including a button board 110 and a supplementary light board 120. The button board 110 is provided with a plurality of buttons 111 arranged at intervals. The supplementary light board 120 is provided with LED light groups 121, each LED light group 121 including a plurality of LED beads. The plurality of LED light groups 121 are arranged one-to-one with the plurality of buttons 111. The supplementary light board 120 and the button board 110 are sequentially attached along the thickness direction and electrically connected to each other. Each LED light group 121 is used to provide a light source to one button 111.

[0035] The fact that the button panel 110 and the fill light panel 120 are attached in the thickness direction can be understood as that one side of the button panel 110 in the thickness direction is attached to one side of the fill light panel 120 in the thickness direction.

[0036] The button module generally also includes a touch panel 140, on which multiple button symbols 141 are set. The multiple button symbols 141 correspond one-to-one with multiple buttons 111. The touch panel 140 is connected to the side of the button panel 110 away from the fill light panel 120. It can be understood that the user directly presses the touch panel 140, thereby pressing the button 111 under the touch panel 140.

[0037] Understandably, since the button panel 110 and the fill light panel 120 are attached in the thickness direction in this embodiment, the distance between the LED light group 121 on the fill light panel 120 and the button 111 on the button panel 110 is less than the sum of the thickness of the fill light panel 120 and the thickness of the button panel 110, resulting in a small distance. Each LED light group 121 is used to provide a light source to one button 111 to illuminate it. Each LED light group 121 has multiple LED beads, so the multiple LED beads in each LED light group 121 can provide sufficient light intensity to illuminate the button 111 on the button panel 110, which is sufficient to illuminate the button symbol 141 corresponding to the button 111 on the button panel 110. This avoids obvious light and dark partitions on the button symbol 141 of the touch panel 140 and improves the brightness uniformity of the button symbol 141.

[0038] Optionally, the width of the fill light board 120 is less than or equal to the width of the keypad 110, and the length of the fill light board 120 is less than or equal to the length of the keypad 110, so as to reduce the size occupied by the keypad module in the length and width directions.

[0039] In detail, in this embodiment, the width of the fill light plate 120 is smaller than the width of the button plate 110, and the length of the fill light plate 120 is smaller than the length of the button plate 110.

[0040] It should be noted that the brightness at button 111 here can be understood as the brightness of button 111 at the corresponding button symbol 141. The LED light group 121 is used to provide light source to button 111. This can be understood as the light emitted by the LED beads in the LED light group 121 shining on the button symbol 141 corresponding to button 111, thereby providing light source for the button symbol 141 corresponding to button 111. In other words, the light emitted by the LED beads is used to illuminate the button symbol 141 corresponding to button 111.

[0041] In detail, in this embodiment, the button panel 110 has a plurality of receiving holes 112 corresponding to a plurality of LED light groups 121. The axial direction of the receiving holes 112 is parallel to the thickness direction of the button panel 110. Each LED light group 121 is installed in a receiving hole 112. The button 111 is located on the side of the button panel 110 away from the receiving hole 112 and away from the supplementary light plate 120.

[0042] In this embodiment, button 111 is located on the outer periphery of the corresponding receiving hole 112.

[0043] Understandably, the LED beads in each LED light group 121 can provide light to the button symbol 141 corresponding to the button 111 through the receiving hole 112. Furthermore, due to the arrangement of the receiving hole 112, the interference between the light emitted by the LED beads in adjacent LED light groups 121 can also be reduced.

[0044] Each LED light group 121 and the corresponding receiving hole 112 are symmetrical about a preset plane, thereby improving the uniformity of the light emitted by the LED light group 121 on the button symbol 141.

[0045] In detail, in this embodiment, the LED light group 121 includes two LED beads, and multiple LED light groups 121 are arranged at intervals along the length direction of the supplementary light board 120, and the two LED light groups 121 are also arranged at intervals along the length direction of the supplementary light board 120.

[0046] In this embodiment, multiple buttons 111 on the button panel 110 are also arranged at intervals along the length direction of the button panel 110, and button symbols 141 on the touch panel 140 are also arranged at intervals along the length direction of the touch panel 140. Multiple button symbols 141 are set in one-to-one correspondence with multiple buttons 111. The button symbols 141 can be button symbols 141 with different functions silkscreened on the touch panel 140.

[0047] It should be noted that "multiple" in this embodiment can be understood as two or more quantities.

[0048] The fill light board 120 is also equipped with multiple conductive through holes 122. The fill light board 120 is electrically connected to the button board 110 through the conductive through holes 122. The multiple conductive through holes 122 are divided into multiple groups, and the multiple groups of conductive through holes 122 are electrically connected to multiple groups of LED light groups 121 one by one.

[0049] It is understandable that the conductive via 122 can be understood as being formed through a via metallization process. Since the supplementary light board 120 is electrically connected to the keypad 110 through the conductive via 122, the number of terminals on the supplementary light board 120 and the keypad 110 can be reduced, thereby reducing the occurrence of poor contact due to the connection between the terminals and the electrical connection wires.

[0050] In detail, in this embodiment, the fill light board 120 is welded to the button board 110 to improve the connection strength between the fill light board 120 and the button board 110. For example, the conductive through hole 122 of the fill light board 120 can be welded to the button board 110.

[0051] It should be noted that the fill light board 120 in this embodiment is a PCB circuit board. Of course, the button board 110 can also be a PCB circuit board.

[0052] In detail, in this embodiment, the outer wall of the supplementary lighting plate 120 is provided with a conductive through hole 122. The inner peripheral wall of the conductive through hole 122 is an arc-shaped inner wall with an opening. The opening direction of the conductive through hole 122 forms an angle with the axial direction of the conductive through hole 122. In this embodiment, the opening direction of the conductive through hole 122 is perpendicular to the axial direction of the conductive through hole 122.

[0053] Understandably, since the conductive through hole 122 is located on the outer wall of the supplementary light plate 120 and the conductive through hole 122 has an opening, it is also convenient for operators to weld the conductive through hole 122 to the button plate 110.

[0054] In this embodiment, in order to further improve the uniformity of the light emitted by the LED light beads in the LED light group 121 illuminating the button symbol 141, this embodiment also includes a light-diffusing film 130. The touch panel 140, the light-diffusing film 130, the button board 110 and the supplementary light board 120 are stacked in sequence.

[0055] In detail, in this embodiment, both sides of the light-diffusing film 130 are coated with adhesive, and both sides of the light-diffusing film 130 are respectively bonded to the touch panel 140 and the keypad 110. Since the light-diffusing film 130 bonds the touch panel 140 and the keypad 110 together with adhesive, the fit between the keypad 110 and the touch panel 140 is improved, so as to ensure that when the user presses the key symbol 141, the key 111 below the key symbol 141 has consistent sensitivity.

[0056] This utility model also provides a door lock 1, which includes the aforementioned button module. The door lock 1 also includes a mounting housing 200. The button module is assembled and installed within the mounting housing 200, and a touch panel 140 covers the mounting housing 200. To facilitate user disassembly and assembly of the mounting housing 200 and the button module, the button module is typically detachably connected to the mounting housing 200 using threaded fasteners. Furthermore, since the door lock 1 includes the button module, it also possesses the same technical effects as the button module; therefore, the technical effects of the door lock 1 will not be elaborated upon here.

[0057] In summary, this utility model embodiment provides a button module and a door lock 1. The door lock 1 includes a button module, which includes a button board 110 and a supplementary light board 120. The button board 110 is provided with a plurality of buttons 111 arranged at intervals. The supplementary light board 120 is provided with LED light groups 121. Each LED light group 121 includes a plurality of LED beads. The plurality of LED light groups 121 are arranged one-to-one with the plurality of buttons 111. The supplementary light board 120 and the button board 110 are sequentially attached along the thickness direction and electrically connected to each other. Each LED light group 121 is used to provide a light source to one button 111. Each LED light group 121 has multiple LED beads. Therefore, the multiple LED beads in each LED light group 121 can provide sufficient light intensity to illuminate the buttons 111 on the keypad 110, which is sufficient to illuminate the button symbols 141 corresponding to the buttons 111 on the keypad 110. This avoids obvious light and dark partitions on the button symbols 141 of the touch panel 140 and improves the brightness uniformity of the button symbols 141.

[0058] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
