Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

The disclosed embodiment provides a door lock, fig. 1 is a schematic structural view of the door lock, and referring to fig. 1, the door lock includes a housing 10, a key assembly 20, and an illumination assembly 30. One side of the housing 10 has a touch area 110, the touch area 110 being near an edge of one side of the housing 10. The key assembly 20 is located in the housing 10, and the key assembly 20 is opposite to the touch area 110. The illumination assembly 30 is directed toward the face of the touch area 110 for illuminating the touch area 110.

The touch area 110 is for a user to touch to input information, and the key assembly 20 is in contact with the touch area 110 to receive information. Since the touch area 110 is located at the edge of one side of the housing 10, the concealment of the user during operation can be improved, and peeping by other people can be effectively avoided. In addition, since the touch area 110 is located at the edge of one side of the housing 10, the occupied area of the touch area 110 on the housing 10 can be reduced, so that the area of the housing 10 can be fully planned and utilized, and other components can be better arranged. In addition, the touch area 110 can be illuminated by the illumination assembly 30, thereby functioning as illumination.

With continued reference to fig. 1, in this embodiment, the door lock further includes a handle 50. The handle 50 is connected to one side of the housing 10, the handle 50 is located on the same side of the housing 10 as the touch area 110, and the handle 50 is located on one side of the touch area 110.

Since the handle 50 and the touch area 110 are located on the same surface of the housing 10, and the handle 50 is located on one side of the touch area 110, the handle 50 can play a certain role in shielding the touch area 110, so that the concealment of the user during operation can be improved, and peeping by other people can be effectively avoided.

It should be noted that, the handle 50 is adjacent to the touch area 110, which means that the front projection of the handle 50 on the housing 10 is adjacent to the touch area 110, that is, on the side of the housing 10 where the touch area 110 is located, the handle 50 is adjacent to the touch area 110, so that the handle 50 and the touch area 110 are eccentrically disposed on the housing 10.

With continued reference to fig. 1, in this embodiment, the touch area 110 has a plurality of touch sub-areas 111 therein, and the plurality of touch sub-areas 111 are arranged at intervals.

The touch area 110 is a set of a plurality of touch sub-areas 111, the outline of the touch area 110 is the outline of a pattern surrounded by all the touch sub-areas 111, and all the touch sub-areas 111 are located in the touch area 110.

In the above implementation, each touch sub-area 111 corresponds to one type of input information. For example, characters 1, 2, 3, 4, etc. in fig. 1, each corresponding to one touch sub-area 111, icons ∈, < etc., each corresponding to one touch sub-area 111, and the user can input corresponding information by touching the corresponding touch sub-area 111. In the present disclosure, there is no limitation on the number of touch sub-areas 111. In addition, since the plurality of touch sub-areas 111 are arranged at intervals, the possibility of false touch can be effectively avoided.

In some examples, the plurality of touch sub-areas 111 are arranged sequentially along the length of the handle 50.

The touch sub-areas 111 are arranged in such a way that the handle 50 can act as a guide for the user's line of sight, so that the user can operate the plurality of touch sub-areas 111.

For example, as shown in fig. 1, the handle 50 is an elongated structural member, and then the plurality of touch sub-areas 111 are sequentially arranged along a straight line accordingly. In other embodiments, if the handle 50 is other shaped, such as an arc, the plurality of touch sub-areas 111 are correspondingly arranged in sequence along the arc. The present disclosure is not limited in this regard.

In other examples, the plurality of touch sub-areas 111 are arranged in an array.

The touch subareas 111 are arranged in such a way, so that the touch subareas 111 are more concentrated, and the operation of a user is facilitated.

For example, a matrix arrangement, i.e., each touch sub-area 111 is arranged to form a rectangular array. Or, the touch sub-areas 111 are arranged in an annular array, that is, the touch sub-areas are arranged to form an annular array.

With continued reference to fig. 1, in the present embodiment, the key assembly 20 includes a touch circuit board 210. The orthographic projection of the touch circuit board 210 on the plane of the touch area 110 is at least partially located in the touch area 110.

In the above implementation, the key assembly 20 is a capacitive touch key, and the touch circuit board 210 is a printed circuit board, and has a circuit and a touch IC corresponding to the capacitive touch key. When a finger of a user touches the touch area 110 on the housing 10, the finger forms one pole of the capacitive plate, and the circuit copper sheet on the touch circuit board, or the like, i.e. the sensing area forms the other pole of the capacitor, so that a new capacitor is formed between the two poles, thereby changing the total capacitance on the touch circuit board, and further identifying the input of the user.

In other examples, the key assembly 20 is a mechanical key, and the touch area 110 of the housing 10 is elastically deformed by pressing the touch area 110, so as to trigger a button of the key assembly 20.

In the present embodiment, the length direction of the touch circuit board 210 coincides with the length direction of the handle 50.

In the above implementation manner, the length direction of the touch circuit board 210 is related to the length direction of the touch circuit board 210, so that the length direction of the touch circuit board 210 is consistent with the length direction of the touch area 110, thereby facilitating the mutual matching between the touch area 110 and the touch circuit board 210.

With continued reference to fig. 1, in this embodiment, the lighting assembly 30 includes a first light emitting assembly 310. The first light emitting component 310 is located in the housing 10, where the first light emitting component 310 is located opposite to the touch area 110, and the touch area 110 transmits light.

In the above implementation, the first light emitting component 310 can emit light after being powered. Since the touch area 110 transmits light, light emitted from the first light emitting element 310 can be transmitted through the touch area 110, thereby playing a role of illumination, and facilitating a touch operation by a user.

Illustratively, the touch area 110 is made of light-transmitting polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), poly (bis-allyldiglycol carbonate) CR-39, and the like, and the first light emitting component 310 is opposite to the touch area 110, so that light generated by the first light emitting component 310 can be transmitted through the touch area 110.

The first light emitting component 310 is located on a side of the key component 20 facing away from the touch area 110, and a length direction of the first light emitting component 310 is consistent with a length direction of the key component 20.

In the above implementation manner, the light emitted by the first light emitting element 310 is sequentially emitted through the key assembly 20 and the touch area 110, so that the first light emitting element 310 can be prevented from shielding the touch area 110, and thus the operation reliability of the key assembly 20 is ensured. In addition, the longitudinal direction of the first light emitting element 310 is designed to be identical to the longitudinal direction of the key element 20, so that the first light emitting element 310 can be ensured to sufficiently illuminate the key element 20.

With continued reference to fig. 1, in the present embodiment, the first light emitting assembly 310 includes a driving backplate 311 and a light emitting member 312. The longitudinal direction of the drive back plate 311 coincides with the longitudinal direction of the handle 50. The light emitting pieces 312 are located on one surface of the driving back plate 311 facing the touch area 110, the light emitting pieces 312 are arranged along the length direction of the driving back plate 311, and the light emitting pieces 312 are in one-to-one correspondence with the touch sub-areas 111.

In the above-described implementation, the driving back plate 311 is connected to the inner wall of the housing 10, so that the first light emitting assembly 310 can be stably mounted within the housing 10. The driving back plate 311 provides a mounting base and power for the light emitting element 312 so that the light emitting element 312 can be electrically lighted. The light emitting member 312 is opposite to the touch area 110, so that the light emitted from the light emitting member 312 can be transmitted to the touch area 110 and emitted from the touch area 110.

In addition, since the light emitting elements 312 are in one-to-one correspondence with the touch sub-areas 111, each light emitting element 312 can independently illuminate the corresponding touch sub-area 111, so that the illumination mode of the first light emitting assembly 310 for the touch area can be more diversified.

The light emitting member 312 is an led, so that the light emitting member 312 has the advantages of low power consumption and high brightness by utilizing the characteristics of the led.

In some examples, the drive backplate 311 is fixedly mounted to the inner wall of the housing 10 by screws. In other examples, the drive backplate 311 is fixedly mounted to the inner wall of the housing 10 by adhesive means.

In the present embodiment, the touch circuit board 210 has first holes 211, and the first holes 211 are in one-to-one correspondence with the light emitting elements 312.

In the above implementation manner, since the touch circuit board 210 has the first hole 211, and the first hole 211 corresponds to the light emitting element 312, the light generated by the light emitting element 312 can pass through the first hole 211, so that the touch circuit board 210 does not block the light emitted by the light emitting element 312.

In this embodiment, the key assembly 20 further includes an insulating pad 220. The insulating pad 220 is sandwiched between the touch circuit board 210 and the driving back plate 311, and the insulating pad 220 has second holes 221, and the second holes 221 are in one-to-one correspondence with the light emitting elements 312.

In the above implementation manner, the insulating pad 220 is disposed between the touch circuit board 210 and the driving back plate 311, so that the problem of short circuit between the touch circuit board 210 and the driving back plate 311 can be effectively avoided, and the reliability of the door lock is improved. In addition, since the insulating pad 220 has the second hole 221, and the second hole 221 corresponds to the light emitting element 312, the light generated by the light emitting element 312 can pass through the second hole 221, so that the insulating pad 220 does not block the light emitted by the light emitting element 312.

It is easy to understand that the touch sub-area 111, the first hole 211, the second hole 221 and the light emitting member 312 are in one-to-one correspondence, and the light generated by the light emitting member 312 sequentially passes through the second hole 221 and the first hole 211, and is finally transmitted out of the housing 10 by the corresponding touch sub-area 111.

Illustratively, the insulating pad 220 is opaque, and the light emitting member 312 is disposed in the corresponding second hole 221.

In the above implementation manner, by utilizing the light-tight characteristic of the insulating pad 220, the light generated by the light emitting element 312 in the second hole 221 can only be emitted to the corresponding first hole 211 through the second hole 221, so that the unnecessary light emission of other touch sub-areas due to light divergence is effectively avoided.

Illustratively, the insulating pad 220 is a silicone pad.

With continued reference to fig. 1, in some examples, a surface of the touch circuit board 210 facing the insulating pad 220 has at least two positioning holes 230, the positioning holes 230 are arranged along a length direction of the touch circuit board 210, a surface of the insulating pad 220 facing the touch circuit board 210 has at least two positioning protrusions 240, the positioning protrusions 240 are arranged along the length direction of the insulating pad 220, and the positioning protrusions 240 are inserted into the corresponding positioning holes 230.

In other examples, at least two positioning protrusions 240 are disposed on a surface of the touch circuit board 210 facing the insulating pad 220, the positioning protrusions 240 are arranged along the length direction of the touch circuit board 210, at least two positioning holes 230 are disposed on a surface of the insulating pad 220 facing the touch circuit board 210, the positioning holes 230 are arranged along the length direction of the insulating pad 220, and the positioning protrusions 240 are inserted into the corresponding positioning holes 230.

Through the cooperation between the positioning protrusion 240 and the positioning hole 230, the positioning installation between the touch control circuit board 210 and the insulating pad 220 is ensured, so that the assembly efficiency of the door lock is improved, and the assembly accuracy is also improved.

With continued reference to fig. 1, in this embodiment, the door lock further includes a light homogenizing film 40. One surface of the light homogenizing film 40 is attached to the inner wall of the casing 10, the touch area 110 is covered by the light homogenizing film 40, and the other surface of the light homogenizing film 40 is attached to the key assembly 20.

In the above implementation, the light is transmitted through the light homogenizing film 40 before being transmitted through the touch area. Under the action of the light homogenizing film 40, the light transmitted through the touch area can be softer.

Illustratively, one surface of the light homogenizing film 40 is adhered to the inner wall of the casing 10, and the other surface of the light homogenizing film 40 is adhered to the touch circuit board 210, so that not only can the light homogenizing effect be achieved, but also the touch circuit board 210 can be tightly adhered to the inner wall of the casing 10, so as to ensure the sensitivity of the touch circuit board 210.

Fig. 2 is an exploded view of the door lock, the view angle of fig. 2 is the view angle a of fig. 1, and in combination with fig. 2, in this embodiment, the inner wall of the housing 10 has a mounting surface 120, the mounting surface 120 and the touch area 110 are located on opposite sides, the mounting surface 120 is a plane, the mounting surface 120 and the touch area 110 are close to the same side edge of the housing 10, and the length direction of the mounting surface 120 is consistent with the length direction of the touch circuit board 210. The touch circuit board 210 and the first light emitting component 310 are sequentially stacked on the mounting surface 120.

Illustratively, the mounting surface 120 is attached to the light homogenizing film 40, so as to provide a smooth mounting base for the light homogenizing film 40, the touch circuit board 210, the insulating pad 220, and the driving back plate 311.

The inner wall of the housing 10 is in a circular arc shape, the mounting surface 120 is a plane cut out on the inner wall of the housing 10, and the mounting surface 120 is parallel to the touch area 110, so that the key assembly 20 and the first light emitting assembly 310 mounted on the mounting surface 120 can be parallel to the touch area 110, the key assembly 20 can be triggered by the operation of the user on the touch area 110 more sensitively, and the light emitted by the first light emitting assembly 310 can be transmitted through the touch area 110 better.

Further, since the mounting surface 120 and the touch area 110 are located on opposite sides, the operation on the touch area 110 can be directly fed back to the mounting surface 120, thereby facilitating the key assembly 20 mounted on the mounting surface 120 to acquire a corresponding operation.

The mounting surface 120 has a positioning post 130, the dodging film 40, the touch control circuit board 210 and the insulating pad 220 are sequentially sleeved on the positioning post 130, and the screw for mounting the driving back plate 311 is inserted into the positioning post 130.

Through the positioning column 130, the positioning and mounting of the dodging film 40, the touch control circuit board 210 and the insulating pad 220 on the mounting surface 120 can be realized, so that not only is the assembly efficiency of the keyboard device improved, but also the assembly accuracy is improved.

The second light emitting assembly 320 is located at an outer wall of the handle 50 and is disposed along a length direction of the handle 50, and the second light emitting assembly 320 faces the touch area 110.

In the above-described implementation, the touch area 110 can be illuminated with the aid of the second light emitting assembly 320, thereby facilitating the operator's manipulation of the touch area 110.

Also, since the second light emitting assembly 320 is disposed along the length direction of the handle 50, it is possible to ensure a large area of the second light emitting assembly 320 disposed on the handle 50, thereby sufficiently illuminating the touch area 110.
