Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The core of the invention is to provide a wearable device which is convenient for switching a display screen.
Please refer to fig. 1-12, which are drawings illustrating the present invention.
Referring to fig. 1 to 3, the present invention provides a wearable device, which includes a body, a display screen, a roller operation key 1, a gear transmission mechanism, a magnet, a sensor 3, and a processor 4.
Specifically, the body mainly plays the bearing effect, and its major structure is mainly decided by the product type of wearing equipment, and for example, wearing equipment can be wrist-watch, bracelet, intelligent glasses or helmet etc. and technical personnel in the art can design the major structure of body according to the specific product type of wearing equipment, refer to the conventional structure that corresponds the product type among the prior art.
The body is located to the display screen, and the display screen is used for showing information, for example time information, temperature information, motion mode information or heart rate information etc..
The roller operation key 1 is rotatably disposed on the body, and it can be understood that the roller operation key 1 is used for a user to perform a rolling operation, that is, under an external force applied by the user, the roller operation key 1 can be rotated relative to the body.
The input end of the gear transmission mechanism is connected with the roller operating key 1 so as to transmit the movement of the roller operating key 1 through the gear transmission mechanism.
The magnet is connected with the output end of the gear transmission mechanism so as to drive the magnet to move through the gear transmission mechanism when the roller operation key 1 rotates. It will be appreciated that the magnet may generate a magnetic field, which when moved, causes a change in the strength of the magnetic field at the fixed location. The magnetic field intensity of the fixed position is changed due to the movement of the magnet, the distance between the moving process and the fixed position can be changed through the position arrangement of the magnet, or the magnetic pole close to or far from the fixed position in the moving process is changed through the arrangement of the magnetic poles of the magnet.
The sensor 3 is used for detecting the magnetic field intensity change of the magnet when the magnet moves, the sensor 3 is connected with the processor 4, and when the sensor 3 detects the magnetic field intensity change of the magnet, a detection signal is sent to the processor 4, so that the processor 4 controls the display screen to switch the display content according to the detection signal of the sensor 3.
That is to say, the invention drives the gear transmission mechanism to act by rotating the roller operating key 1, and further the output end of the gear transmission mechanism drives the magnet to move, so that the processor 4 switches the display content of the display screen by using the magnetic field intensity change detected by the sensor 3 when the magnet moves. Compared with the screen switching by controlling the touch screen, the roller operating key 1 is convenient to operate and not limited by the size of the display screen, and brings convenience to the screen switching operation of a user.
In addition, when the roller wheel operation key 1 rotates, the motion is transmitted through the gear transmission mechanism, and when the gear transmission mechanism acts, the feeling of constantly switching gears is given to people, so that the hand feeling can be improved, and the user experience is good. Moreover, the magnet can have a proper angular speed by reasonably designing the transmission ratio of the gear transmission mechanism, so that the sensor 3 can better sense the magnetic field intensity change of the magnet. Moreover, because the magnetic field of the magnet exists in the physical space, the magnetic field is a special invisible and untouchable field, therefore, the sensor 3 only needs to be positioned in the magnetic field of the magnet, the magnet and the sensor 3 do not need to be aligned or an obstacle and the like do not need to be arranged between the magnet and the sensor 3, namely, the sensor 3 is utilized to detect the detection mode of the magnetic field intensity change of the magnet, the relative position of the magnet and the sensor 3 is conveniently and flexibly set, the positions of the sensor 3 and the magnet can be reasonably designed according to the overall layout of the wearable device, and the optimal design and the product assembly are facilitated.
It should be noted that the present invention does not limit the specific structure of the sensor 3, the detection principle thereof, and the like, as long as the sensor 3 can detect the magnetic field intensity change of the magnet and the variation thereof when the magnet moves. Preferably, the sensor 3 is a hall sensor 3. It can be understood that when the magnetic field intensity changes, the voltage of the hall sensor 3 will change accordingly, the stronger the magnetic field, the higher the voltage, the weaker the magnetic field, and the lower the voltage, therefore, when the voltage of the hall sensor 3 changes, it indicates that the magnetic field intensity of the magnet changes, that is, the magnet moves along with the rotation of the wheel operation key 1, at this time, the hall sensor 3 sends its voltage change signal to the processor 4, so that the processor 4 controls the display to switch the display content according to the voltage change signal of the hall sensor 3. Of course, the sensor 3 can also be another magnetic induction sensor 3 capable of detecting the change of the magnetic field strength of the magnet in the prior art.
Further, after the processor 4 receives the detection signal sent by the sensor 3, the technology that the processor 4 controls the display screen to switch the display content belongs to the mature technology in the prior art, and a person skilled in the art can refer to the prior art, and details are not described herein.
It should be noted that, in this embodiment, the specific structure of the gear transmission mechanism is not limited as long as the gear transmission mechanism can transmit the rotation motion. Preferably, as shown in fig. 1, on the basis of the above embodiment, the gear transmission mechanism includes a driving gear 51 provided to the wheel operating key 1, a driven gear 52 in mesh transmission with the driving gear 51, and an output shaft 53 for providing the driven gear 52, in which case the driven gear 52 and the output shaft 53 form an output end. The driving gear 51 is preferably provided at an end portion of the wheel operating key 1, and when the wheel operating key 1 is rotated, the driving gear 51 is driven to rotate, and the driven gear 52 drives the magnet to rotate through meshing transmission between the driving gear 51 and the driven gear 52. It can be seen that the structure is compact, the transmission of the gear transmission is more accurate, the efficiency is high, the work is reliable, and the service life is long.
In consideration of the specific arrangement of the magnet at the output end of the gear transmission mechanism, as a preferable scheme, on the basis of the above embodiment, as shown in fig. 5, the output end of the gear transmission mechanism is provided with an adaptor 54 capable of rotating together with the output end, the magnet is an annular magnet 2, and the magnet 2 is sleeved on the adaptor 54. It can be understood that, because the magnet 2 is of an annular structure and is sleeved on the adaptor 54, when the adaptor 54 rotates along with the output end of the gear transmission mechanism, it can be always ensured that the adaptor 54 corresponds to the magnet 2 in the 360 ° direction, so as to ensure the reliability of the detection of the sensor 3.
It should be noted that, in this embodiment, the way that the magnet 2 is sleeved on the adaptor 54 is adopted, the setting of the magnet 2 at the output end of the gear transmission mechanism is realized, and the magnet 2 is prevented from being directly arranged on the roller operation key 1, so that the appearance of the roller operation key 1 can be prevented from being damaged when the magnet is assembled on the roller operation key 1 production line, and the rolling effect is prevented from being affected. On the other hand, the mode of sleeving the magnet 2 on the adapter 54 is adopted, so that the process mode of adopting the embedded magnet 2 and magnetizing the embedded magnet is avoided, the process is simplified, and the manufacturing cost is saved.
In addition, in order to change the magnetic field strength at the fixed position when the magnet moves, it is preferable that the central axis of the magnet is not collinear with the rotational axis of the output end of the gear transmission mechanism on the basis of the above-described embodiment. Like this, when gear drive's output rotated, drive the magnet and rotate together, because the central axis of magnet is not the collineation with the axis of rotation of gear drive's output for the eccentric rotation is done to the relative output of magnet, and then makes the distance of magnet relative sensor 3 change, consequently, can make sensor 3 sense the magnetic field intensity change of magnet.
For example, it is preferable that the axis of the adaptor 54 and the axis of the output end of the gear transmission mechanism have a preset distance therebetween to form an eccentric shaft, so that the annular magnet 2 is sleeved on the adaptor 54 to ensure that the central axis of the magnet 2 is not collinear with the rotation axis of the output end of the gear transmission mechanism. When the adaptor 54 rotates with the output end, the magnet 2 rotates eccentrically around the axis of the output end to change the distance between the magnet 2 and the sensor 3, so that the sensor 3 can detect the change of the magnetic field intensity of the magnet 2.
It should be noted that, the specific structure of the adaptor 54 is not limited in this embodiment, for example, the adaptor 54 may be an eccentric shaft disposed at an end of the output end, and the magnet 2 is sleeved on the eccentric shaft. When the output end of the gear transmission mechanism is the driven gear 52, preferably, the adaptor 54 is an eccentric sleeve, which is sleeved on the output shaft 53 of the driven gear 52, and meanwhile, the magnet 2 is sleeved on the outer periphery of the eccentric sleeve. Of course, the eccentric sleeve may be formed as an integral structure with the output shaft 53 for ease of manufacture.
In view of circumferential position limitation of the magnet on the adaptor 54, in the above embodiment, as shown in fig. 4 to 6, the adaptor 54 is provided with a first stop block 541 at an outer circumferential portion close to the output end, the magnet 2 is provided with a first stop groove 21 at an inner circumferential portion, and the first stop groove 21 cooperates with the first stop block 541 to circumferentially limit the magnet 2 and prevent the magnet 2 from circumferentially rotating relative to the adaptor 54.
Further, in consideration of the axial position limitation of the magnet on the adaptor 54 to avoid the magnet from being separated from the adaptor 54 along the axial direction thereof, on the basis of the above embodiment, as shown in fig. 5, the outer peripheral portion of the adaptor 54 away from the output end of the gear transmission mechanism is provided with a second stop block 542, and the first stop block 541 and the second stop block 542 are arranged in a staggered manner along the circumferential direction of the adaptor 54; as shown in fig. 4, the inner circumference of the magnet 2 is provided with a second limiting groove 22, the first limiting groove 21 is communicated with the second limiting groove 22, so that the second stop block 542 can pass through the communication part between the first limiting groove 21 and the second limiting groove 22, one end of the second limiting groove 22 in the axial direction of the magnet 2 is open, the other end of the second limiting groove 22 is provided with a stop portion 221, and the stop portion 221 is used for being matched with the second stop block 542 to axially limit the magnet 2.
It should be noted that the width of the second stopper 542 along the circumferential direction of the adaptor 54 is smaller than or equal to the width of the first stopper groove 21 along the circumferential direction of the magnet 2, so that the second stopper 542 can pass through the first stopper groove 21. Preferably, the width of the first stop block 541 and the width of the second stop block 542 along the circumferential direction of the adaptor 54 are the same, so that the first limiting groove 21 can pass through the second stop block 542, and the first limiting groove 21 is finally matched with the first stop block 541.
When the magnet 2 and the adaptor 54 are assembled, first, the first limit groove 21 of the magnet 2 is aligned with the second stop block 542, and the magnet 2 is pushed onto the adaptor 54 along the axial direction, so that the magnet 2 is gradually close to the output end of the gear transmission mechanism, and in the process, the first limit groove 21 slides along the second stop block 542. It can be understood that the width of the stopping portion 221 along the axial direction of the magnet 2 is smaller than the axial distance between the first stopping block 541 and the second stopping block 542, so that when the magnet 2 is pushed to the axial position of the first stopping block 541, the stopping portion 221 can pass through the axial distance between the first stopping block 541 and the second stopping block 542 by rotating the magnet 2, in this process, the communication position between the first limiting groove 21 and the second limiting groove 22 crosses over the second stopping block 542, finally, the second limiting groove 22 is rotated to the position aligned with the second stopping block 542, and the first limiting groove 21 is aligned with the first stopping block 541, and then the magnet 2 is further pushed onto the adapting member 54 along the axial direction, so that the magnet 2 is further close to the output end of the gear transmission mechanism until the magnet is pushed to be stopped, in this process, the first limiting groove 21 slides along the first stopping block 541. When the magnet 2 is pushed to be fixed, the magnet 2 is installed in place, at the moment, the output end of the gear transmission mechanism carries out axial limiting on the magnet 2 so as to limit the maximum axial position of the magnet 2 sleeved on the adapter 54, and meanwhile, the magnet 2 is circumferentially limited by the matching of the first limiting groove 21 and the first stop block 541; and the stopping portion 221 of the second limiting groove 22 is used to axially limit one side of the second stop block 542 close to the first stop block 541, so as to prevent the magnet 2 from being separated from the adaptor 54.
Preferably, the overall arc length of the first stop block 541 and the second stop block 542 along the circumferential direction of the adaptor 54 is equal to the overall arc length of the first limiting groove 21 and the second limiting groove 22 along the circumferential direction of the magnet 2, so that after the magnet 2 and the adaptor 54 are assembled, the first stop block 541 is matched with the first limiting groove 21, and one side of the second stop block 542, which is far away from the first stop block 541, is in contact with the groove wall of the second limiting groove 22, so that the first stop block 541 and the second stop block 542 are used for simultaneously performing circumferential limiting on the magnet 2, thereby preventing the magnet 2 from rotating circumferentially on the adaptor 54 and affecting the detection accuracy of the sensor 3.
As shown in fig. 6, which is a cross-sectional view of the magnet 2 and the adaptor 54 after being assembled, when the magnet 2 is installed in place, in order to ensure the fixation of the magnet 2, it is preferable to apply hot melt to the middle points of the first limiting groove 21 and the second limiting groove 22 of the magnet 2, so that the magnet 2 is more firmly fixed on the adaptor 54.
Further, in view of the convenience of assembly, at the same time, since the roller operation key 1 needs to be partially exposed to the outside, resulting in poor sealing performance at the roller operation key 1, for waterproofing, on the basis of the above-described embodiment, as shown in fig. 7 and 8, the body includes the first carrier 6 and the second carrier 7, the first carrier 6 is used for mounting the roller operation key 1, and the second carrier 7 is used for mounting the output end (e.g., the driven gear 52 and the output shaft 53) of the gear transmission mechanism. Specifically, the roller operation key 1 is rotatably mounted in the first bearing body 6, and the first bearing body 6 is provided with a yielding groove 61 for exposing part of the outer side surface of the roller operation key 1; the output end of the gear transmission mechanism is rotatably arranged in the second bearing body 7; the first carrier 6 is connected to the second carrier 7 in a sealing manner. That is to say, in the embodiment, the first supporting body 6 is connected to the second supporting body 7 in a sealing manner, so that the waterproof function between the first supporting body 6 and the second supporting body 7 is achieved, and water seepage from the joint of the first supporting body 6 and the second supporting body 7 is avoided.
It should be noted that, in this embodiment, a specific implementation manner of the sealing connection between the first carrier 6 and the second carrier 7 is not limited, and preferably, as shown in fig. 12, a sealing gasket 8 (e.g., a silicone gasket) is disposed at a connection position of the first carrier 6 and the second carrier 7, and the first carrier 6 and the second carrier 7 are fixedly connected through a locking screw 9. That is, the sealing gasket 8 (such as a silicone gasket) is used to seal the joint between the first carrier 6 and the second carrier 7. In view of the convenience of the arrangement of the sealing pad 8 (e.g. a silicone pad), it is preferable that the second carrier 7 is provided with a sealing groove in which the sealing pad 8 (e.g. a silicone pad) is fixed by means of a back adhesive, as shown in fig. 10.
Further, in order to achieve the waterproof between the first carrier 6 and the body and the waterproof between the second carrier 7 and the body, on the basis of the above embodiments, the first carrier 6 and the second carrier 7 are connected to form an integrated module, and the integrated module and the body are sealed. That is to say, first supporting body 6 and second supporting body 7 sealing connection back, the whole relative body of integrated module that forms is waterproof, avoids aqueous vapor etc. to get into this integrated module after groove 61 department of stepping down from installation gyro wheel manipulating key 1, gets into inside the body from this integrated module, reaches the inside waterproof effect of carrying on of body.
Preferably, the first bearing body 6 and the second bearing body 7 are connected to form an integrated module with an opening only at the position of the abdicating groove 61, the integrated module is not sealed except the position of the abdicating groove 61, the roller operation key 1 and the gear transmission mechanism are installed inside the integrated module, when water vapor enters the integrated module from the position of the abdicating groove 61, the water vapor cannot permeate the inside of the body except the integrated module from other parts of the integrated module, so that a waterproof effect is achieved, the wearable device can meet the 5ATM waterproof requirement, and the reliability of the wearable device is improved.
It can be understood that, this embodiment requires that the first carrier 6 and the second carrier 7 have sealing performance, for example, the first carrier 6 may be a box structure with an open end, the side of the second carrier 7 away from the yielding groove 61 is an open structure, the other parts are sealed, when the first carrier 6 and the second carrier 7 are connected, the open ends of the two are opposite, and then the two are fixedly connected, that is, after the first carrier 6 and the second carrier 7 are connected, the formed integrated module is a box structure with only the yielding groove 61.
It can be seen that, in the embodiment, the roller operation key 1, the gear transmission mechanism, the first bearing body 6 and the second bearing body 7 are assembled to form an integrated module, which is waterproof, facilitates the integral installation of the integrated module, and provides convenience for the installation of the roller operation key 1 and the gear transmission mechanism on the body.
In addition, in the present embodiment, the specific installation manner of the wheel operation key 1 on the first carrier 6 is not limited, as long as the installation manner that the wheel operation key 1 can rotate can be realized. Preferably, as shown in fig. 7, the first carrier 6 is provided with a first mounting groove 62, and the rotating shaft of the roller operation key 1 is mounted in the first mounting groove 62. In this configuration, as shown in fig. 8, the second carrier 7 is provided with a second mounting groove 71, and when the first carrier 6 is connected to the second carrier 7, the first mounting groove 62 and the second mounting groove 71 form an integral pivot mounting hole surrounding the outer periphery of the pivot of the wheel operation key 1, so that the pivot of the wheel operation key 1 is rotated in the pivot mounting hole. It can be understood that, in the assembly circulation process, in order to avoid the roller operation key 1 from falling off from the first bearing body 6, the roller operation key 1 and the first bearing body 6 need to be pre-fixed by means of a tool, and when the first bearing body 6 is connected with the second bearing body 7, the tool is detached.
Further, the present embodiment does not limit the arrangement manner of the output end of the gear transmission mechanism on the second carrier 7, and as a preferable scheme, on the basis of the above embodiment, as shown in fig. 8, the output end includes an output shaft 53, the second carrier 7 is provided with a third mounting groove 72 for supporting the output shaft 53 and a blind mounting hole 73 for inserting one end of the output shaft 53 to axially limit the same; the second supporting body 7 is connected with a pressing block 74, and the pressing block 74 is pressed at the opening end of the third mounting groove 72 to limit the output shaft 53 in the radial direction.
During installation, after the magnet is connected with the output end, the assembly formed by the output end and the magnet is installed on the first bearing body 6, at the moment, the output shaft 53 is installed in the third installation groove 72, so that the third installation groove 72 supports the output shaft 53, then, the assembly formed by the output end and the magnet is pushed, one end of the output shaft 53 is inserted into the installation blind hole 73 until the output shaft cannot be pushed, and the output shaft 53 is axially positioned by using the installation blind hole 73. At this moment, the circular inner wall of the installation blind hole 73 plays a radial limiting role for the end of the output shaft 53, in order to better perform radial limiting on the output shaft 53, after the blind hole 73 is inserted into one end of the output shaft 53, the pressing block 74 is pressed at the opening end of the third installation groove 72, the pressing block 74 is provided with a fourth installation groove, and after installation, the fourth installation groove and the third installation groove 72 form a whole installation hole of the output shaft 53 so as to perform radial limiting on the output shaft 53. After the pressing block 74 is pressed at the open end of the third mounting groove 72, the pressing block 74 is preferably fixedly connected with the second supporting body 7 by a pressing block screw 75.
