Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
Embodiments of the present invention relate to a knob provided on an electronic device, for example, as shown in fig. 1, a knob 1 is provided in a shown position on a wristwatch, and the knob 1 penetrates through one side surface of a case 2. The user can control the watch by rotating the portion of the knob 1 exposed outside the case 2. The illustrated wristwatch is further provided with a cover 3, and the user can control the wristwatch by closing or opening the cover 3.
In addition, the knob can also be arranged on other electronic equipment such as an intelligent lamp and a remote controller, and the examples are not to be considered here at all.
The structure of the knob of the embodiment of the invention is shown in fig. 2, and comprises: the rotating device 12 penetrates through one side surface of the electronic device shell, the rotating device 12 comprises a contact part 121 positioned outside the shell and an identification part 122 positioned inside the shell, the contact part 121 and the identification part 122 rotate synchronously along the same rotating shaft, and as shown in fig. 3, the identification part 122 is provided with at least one groove along the periphery of the rotating shaft; the sensor 11 is arranged in the shell, the sensor 11 is arranged opposite to the identification part 122, the sensor 11 is used for identifying at least one groove of the identification part 122, the change of the at least one groove is used for determining the rotation angle of the rotating device 12, and the rotation angle is used for indicating a preset instruction.
Compared with the prior art, the embodiment of the invention has the advantages that the at least one groove is formed in the identification part of the rotating device in the shell, the sensor arranged opposite to the identification part is used for detecting the change of the at least one groove so as to determine the rotating state of the rotating device, and different rotating states are used for indicating different preset instructions, so that the preset instructions are sent through the knob.
In addition, the sensor 11 is used to recognize a change in distance from the at least one groove during rotation of the recognition portion, and determine a rotation angle or a rotation direction based on the change in distance. In the rotating process of the rotating device, the position, right opposite to the sensor and the identification part, of the sensor passes through the setting position of the groove, the distance data detected when the sensor and the groove are in right alignment and the distance data detected when the sensor and the rest positions of the identification part are in right alignment are different, the distance data obtained by the sensor and the distance data are different, the sensor can determine whether a user issues control operation on the intelligent equipment according to the distance change, and then a preset instruction is generated and sent, so that the preset instruction is sent through the knob.
For example, in the case where the identification part is rotated clockwise or counterclockwise, the distance change from the edge at two positions of the groove, which is recognized by the sensor, is different, and the rotation direction of the identification part can be determined according to the recognized distance change trend. As shown in fig. 4 and 5, fig. 4 shows the distance change between the sensor and the groove in the clockwise rotation process, and fig. 5 shows the distance change between the sensor and the groove in the counterclockwise rotation process, so that the groove change trends corresponding to different rotation directions can be visually observed to be completely different, and the rotation direction of the rotating device can be accurately judged according to the groove change.
Or the profile of the groove is adjusted, so that the distance between the sensor and the groove is different when the rotating device rotates to different angles, namely the rotating angle corresponds to the distance data one by one, the rotating angle of the rotating device can be determined according to the detected distance data, and different preset instructions correspond to different rotating angles, so that the preset instructions are sent through the knob.
In addition, as shown in fig. 6, the first transition area 131 and the second transition area 132 are formed on the identification part 122 along the rotation direction groove 13 of the identification part 122; the first transition area 131 and the second transition area 132 have different trends in the rotational direction. Due to the fact that the first transition area 131 and the second transition area 132 have different changing trends, when the position, facing the recognition part 122, of the sensor 11 passes through the first transition area 131, the detected distance changing trend is different from that when the position passes through the second transition area 132, when the sensor 11 detects different distance changes, different preset instructions are correspondingly sent, and therefore a plurality of control instructions are sent through the knob.
With regard to the setting of the trend of the first transition area 131 and the second transition area 132 in the rotation direction, the trend of the distance change detected when the facing position of the sensor 11 and the identification portion 122 passes through the first transition area 131 and when the facing position passes through the second transition area 132 can be distinguished by changing the slope of the plane formed between the first transition area 131 and the second transition area 132 and the identification portion, respectively. The greater the difference between the slope of the plane formed between the first transition region 131 and the recognition part and the slope of the plane formed between the second transition region 132 and the recognition part, the better the recognition effect of the sensor 11.
In addition, the surfaces formed between the first transition area 131 and the second transition area 132 and the identification portion may be curved surfaces, and the change trend of the distance between the facing positions of the sensor 11 and the identification portion 122 passing through the first transition area 131 and the facing positions of the second transition area 132 passing through the second transition area 132 may be distinguished by changing the radius of curvature of the curved surfaces formed between the first transition area 131 and the identification portion 132 and the curved surfaces.
In addition, the first transition area and the second transition area are arranged on the opposite edges of the identification part and the groove respectively in a chamfering mode, and corresponding chamfering angles of the first transition area and the second transition area are different. The first transition area and the second transition area with different profile change trends are formed in a chamfering mode, and the operation is convenient.
In addition, when the identification portion is provided with the groove, one side of the groove may be set in a C-angle chamfering manner, the other side of the groove may be set in a right-angle chamfering manner, the region corresponding to the C-angle may be used as the first transition region, and the region corresponding to the right angle may be used as the second transition region, so that the first transition region 131 and the second transition region 132 formed may have different changing tendencies in the rotation direction.
In addition, the sensor 11 determines whether the rotation direction of the recognition part 122 is clockwise or counterclockwise based on the distance change, and the sensor 11 transmits different preset instructions according to the rotation direction. For example, an open command is issued when a clockwise rotation of the knob is detected, and a close command is issued when a counterclockwise rotation of the knob is detected. Or send an on white light command when a clockwise rotation of the knob is detected, an on soft light command when a counterclockwise rotation of the knob is detected, and so on.
In addition, as shown in fig. 7 to 9, the number of the grooves is plural, each of the plural grooves forms a first transition area and a second transition area on the identification portion, and variation trends of all the formed first transition areas and second transition areas in the rotation direction are different. Because the change trends of the two transition areas of each groove are different, the sensor can identify which transition area the passing transition area passes through, so that different preset instructions are sent according to the difference of the passing transition areas, and the number of the instructions which can be executed by the knob is increased.
In addition, the number of the grooves is multiple, each groove in the multiple grooves forms a first transition area and a second transition area on the identification part, the variation trend of all the first transition areas formed by each groove in the rotation direction is the same, and the variation trend of all the second transition areas formed by each groove in the rotation direction is the same. The arrangement can improve the sensitivity of sensor identification and simplify the control operation of the rotating device, for example, if 2 grooves are uniformly arranged on the identification part, a preset instruction can be sent when a user rotates the knob by at most 180 degrees, and if 4 grooves are uniformly arranged on the identification part, a preset instruction can be sent when the user rotates the knob by at most 90 degrees, so that the complexity of the operation of the user is simplified.
In addition, the groove can be arranged from the edge position of the identification part, and also can be arranged at the middle position of the identification part, and the accurate sending of the preset instruction can be realized only by ensuring that the sensor can be opposite to the groove in the rotation process of the identification part.
In addition, as shown in fig. 2, an abutting portion 14 is disposed at the end of the rotating device 12 near the recognition portion 122, the abutting portion 14 is disposed opposite to the touch sensor 15, and a user can press the knob to contact the abutting portion 14 with the touch sensor 15, so as to generate a preset command different from that generated by the rotation operation. Therefore, the set knob can send the preset instruction more flexibly.
In addition, the preset instructions are all sent to a CPU of the electronic equipment, and the CPU controls the electronic equipment to execute relevant operations.
Embodiments of the invention also relate to an electronic device. The method comprises the following steps: a housing and the above-mentioned knob disposed on the housing. The electronic device can be a watch, an intelligent lamp, a remote controller and the like.
The embodiment of the invention also relates to a control method of the electronic equipment, which is applied to the electronic equipment and comprises the following steps: determining a change in at least one groove in an identification portion of a rotating device in the electronic device and the sensor; determining a rotation angle of the rotating device according to the change of the at least one groove; determining a preset instruction according to the rotation angle; and controlling the electronic equipment according to a preset instruction.
In addition, the method further comprises: determining the rotation direction of the rotating device according to the distance change between the sensor and the edge of the at least one groove; wherein, according to the rotation angle, determining the preset instruction comprises: and determining a preset instruction according to the rotation angle and the rotation direction.
Taking the electronic device as the watch shown in fig. 1 as an example, and the control method of the electronic device is shown in fig. 8, in a case that the user rotates the knob, the sensor triggers generation and sending of the preset instruction by recognizing a distance change generated by a groove formed in the recognition portion of the knob, where how the formed groove causes the distance detected by the sensor to change is described in detail in the above description, and is not described again here. And after receiving the preset instruction, the CPU of the electronic equipment analyzes the preset instruction. If the analyzed instruction is an opening instruction or a closing instruction, detecting the current state of the cover body of the electronic equipment, and if the current state meets the operation of the cover body required by the user, the instruction cannot be executed, and the user is directly reminded that the operation is finished. And if the current state does not meet the operation of the cover body required by the user, executing the instruction, and reminding the user that the instruction is finished after finishing the instruction.
During practical application, the received preset instruction is an uncovering instruction, the state of the existing cover body is an uncovering state, the instruction is not executed and reminds a user of the uncovering state, the received preset instruction is an uncovering instruction, the state of the existing cover body is a covering state, the cover body is controlled to rotate through the rotating shaft so as to be opened, the uncovering instruction is stopped to be executed when the cover body is opened to a required angle, and the user is reminded of completing uncovering operation. And similarly, when the preset instruction is a cover closing instruction and the current state of the cover body is a cover closing state, the instruction is not executed and reminds the user that the cover closing state is achieved, and if the received preset instruction is the cover closing instruction and the current state of the cover body is the cover opening state, the cover body is controlled to rotate through the rotating shaft so as to close the cover body, the cover closing instruction is stopped to be executed when the cover body rotates to a required angle, and the user is reminded that the cover closing operation is completed.
In addition, when the user is reminded, the user can be reminded by using the vibrator or the buzzer. Or the effect of reminding the user is achieved in a mode of flickering the LED lamp, and the mode of reminding the user is not limited.
