Technical Field

With the development of digital technology, the conventional mechanical watch cannot meet the requirement of people for more digital functions, so various digital intelligent watches are appeared on the market. However, as an input mode of the control signal, the crown still inherits the traditional knob input mode.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below.

Aiming at the defects of the existing crown, the embodiment of the invention designs the horizontal crown, adopts the horizontal driving wheel as input, can realize fluctuation and pressing operation by a single hand, has a compact structure, brings better experience to users, and saves the space in the watch.

In order to achieve the above object, referring to fig. 1, an embodiment of the present invention provides a horizontal crown, including: a bracket 1, a control part 2, a driving wheel 3 and a fastener 4; the control part 2 passes through the bracket 1, one end of the control part is fixed on the bracket 1 by a fastener 4, and the other end of the control part is connected with the driving wheel 3. The support 1 is arranged in the watch and used for supporting the control part 2 and the driving wheel 3, the driving wheel 3 is used for inputting rotation and pressure signals, and the control part 2 is used for converting the rotation and pressure signals input by the driving wheel 3 into electric signals, so that the selection and switching functions of the intelligent watch are realized.

The structure of the bracket 1 is shown in fig. 2, a mounting boss 10 is arranged on the bracket, a fastening cavity 11 for mounting the control component 2, a spherical groove 12 and the spherical groove 12 are arranged on the mounting boss 10, and the function of the spherical groove 12 is to assist the control component 2 to convert the input of the driving wheel 3 into rotation and linear movement, and the movement is further detailed below in combination with other components. In addition, the bracket 1 is provided with a first fixing hole 13 for fixing the control member 2 and a second fixing hole 14 for mounting the horizontal crown in the watch.

Fig. 3 to 5 provide a structural diagram of the control part 2, an exploded view and a sectional view, wherein the control part 2 is composed of a driving joint 20, a control rod 21, a supporting cover 23, an encoder 24, a PCB 25, a sensor bracket 26, a sealing ring 27, a spring 28 and a pressure sensor 22; one end of the driving joint 20 is in contact with the control rod 21 and the supporting cover 23, and the control rod 21 passes through the middle of the supporting cover 23 and is coaxial with the supporting cover 23, and the middle is connected with the supporting cover by a pre-tightening spring 28. The supporting cover 23 is installed in the fastening chamber 11 on the bracket 1 in an adhesive or mechanical threaded connection mode, and has the functions of the supporting spring 28 and the driving joint 20, and further, a sealing ring 27 is arranged between the driving joint 20 and the supporting cover 23 for waterproof sealing. The control rod 21 passes through the support cover 23 and then through the encoder 24, and the end is in contact with the pressure sensor 22. The encoder 24 is fixed on a PCB 25, a sensor bracket 26 is arranged on the other side of the PCB, and a pressure sensor 22 is arranged on one side of the sensor bracket 26 close to the tail end of the control rod 21. The PCB 25 is mounted on the first fixing hole 13 of the bracket 1. The control unit 2 functions to convert the rotational and pressing inputs of the driving wheel 3 into two electrical signals, namely the output signal of the encoder 24 and the output signal of the pressure sensor 22. Specifically, the driving joint 20 can freely perform spherical rotation, and when the direction of the rotation axis of the driving joint 20 coincides with the symmetry axis of the control rod 21, the control rod 21 rotates together with the rotation of the driving joint 20, so as to drive the encoder 24 to work. When the rotation direction of the driving joint 20 is perpendicular to the symmetry axis direction of the control rod 21, the output is linear motion, and the control rod 21 moves up and down along the symmetry axis direction along with the rotation of the driving joint 20, so that the control rod 21 can trigger the end pressure sensor 22 to work.

To achieve two output modes of the control part 2, this embodiment provides a drive joint 20 which is externally formed in a spherical shape, as shown in fig. 6. The driving joint 20 is provided with a spherical joint 200, a conical surface hole 201 is arranged above the spherical joint 200, a contact round surface 202 is arranged at the bottom of the conical surface hole 201, and an input handle 203 is arranged at the other end of the spherical joint 200. The ball joint 200 has a spherical outer surface which just mates with the spherical slot 12 on the bracket 1, subject to downward movement restrictions. The upward movement restriction is accomplished by the support cover 23 so that the drive joint 20 can only rotate and cannot translate. The tapered bore 201 and the contact rounded surface 202 at the bottom of the tapered bore 201 form a downwardly concave tapered bore for transmitting the motion of the drive joint 20 to the control rod 21. The contact round surface 202 is a spherical surface, the edge of the contact round surface is tangent to the lower edge of the conical surface hole 201, and the center of the contact round surface is positioned above the spherical center of the spherical joint 200. The input handle 203 is used to connect with the drive wheel 3 and transmit the input of the drive wheel 3 to the ball joint 200.

In order to realize the transmission of the motion inside the control part 2, a control rod 21 is provided in fig. 7, which comprises a support ring 210, a stress spherical surface 211, a resistance increasing groove 212, a dowel bar 213 and a compression surface 214; the supporting ring 210 is in a ring shape, a hemispherical stress sphere 211 is arranged above the supporting ring, a dowel bar 213 with a fixed cross section is arranged below the supporting ring, and a compression surface 214 is arranged at the tail end of the dowel bar 213. The radius of the stress spherical surface 211 is the same as that of the contact spherical surface 202 on the driving joint 20, the driving joint 20 is contacted with the stress spherical surface 211 of the control rod 21 through the contact spherical surface 202, so that rotation is transmitted to the control rod 21 through friction force between the two contact surfaces, in order to increase friction resistance of the contact surfaces, the stress spherical surface 211 is provided with a resistance increasing groove 212, the resistance increasing groove 212 is in a linear groove shape, the cross section of the linear groove is in a conical shape or other shapes, the direction extends from the top of the stress spherical surface 211 to one side of the supporting ring 210, and the resistance increasing groove 212 fills the surface of the stress spherical surface 211 in a circumferential array mode. The effect of the resistance increasing slot 212 is only apparent when subjected to a movement perpendicular to its direction of distribution. For example, in order to make the control rod 21 rotate along the symmetry axis, the driving joint 20 needs to rotate, when the rotation direction of the contact circular surface 202 on the spherical joint 200 is perpendicular to the distribution direction of the resistance increasing grooves 212 on the stress spherical surface 211, the stress spherical surface 211 can obtain the maximum friction resistance (driving force), so that the control rod 21 synchronously rotates under the driving of the spherical joint 200, and the aim from the rotation of the driving joint 20 to the rotation movement of the control rod 21 is achieved. On the other hand, the side, far away from the stressed spherical surface 211, of the supporting ring 210 is contacted with the spring 28, the spring 28 is in a compression pre-tightening state, and the friction resistance between the stressed spherical surface 211 and the contact circular surface 202 is further increased under the thrust of the spring 28.

When the driving joint 20 rotates, but the rotation center line is perpendicular to the direction of the symmetry axis of the control rod 21, the rotation direction of the contact circular surface 202 on the spherical joint 200 is not perpendicular to the distribution direction of the resistance increasing grooves 212 on the stress spherical surface 211, so that the resistance increasing grooves 212 do not provide a function of increasing resistance, and the characteristic of reducing resistance just powerfully realizes the up-and-down movement of the control rod 21. In the above-mentioned rotation process, the ball joint 200 presses the force-bearing spherical surface 211 above the control rod 21 through the upper conical surface hole 201, the force-bearing spherical surface 211 is separated from the contact circular surface 202 under the pressing action, and moves along the direction that the conical surface hole 201 is far away from the sphere center of the ball joint 200, which corresponds to the upward movement of the control rod 21 in the whole, thereby achieving the purpose of moving linearly from the rotation of the driving joint 20 to the control rod 21.

As shown in fig. 8, the supporting cover 23 is provided with a chamber 230, a supporting spherical surface 231, a through hole 232 and a sealing groove 233; the cavity 230 is used for placing the spring 28, the other end of the spring 28 is propped against the support ring 210 on the control rod 21, the through hole 232 is positioned at the center of the bottom of the cavity 230, and the dowel 213 on the control rod 21 just passes through the middle of the through hole 232. The chamber 230 is provided with a supporting sphere 231, which is mainly used for supporting the spherical joint 200 on the driving joint 20 and simultaneously guaranteeing the spherical sliding, and a sealing groove 233 is arranged outside the supporting sphere 231 and is used for installing the sealing ring 27.

The other end of the control part 2 is provided with a PCB board 25, see fig. 5, 9, 10. The PCB 25 is provided with a flexible circuit board 250, a middle hole 251, a mounting hole 252, a sensor bracket 26 and an encoder 24; the pressure sensor 22 is mounted on the sensor support 26, and the pressure sensor 22 may be an inductive pressure sensor, a capacitive pressure sensor or a resistive pressure sensor, which is not limited in this embodiment. The sensor holder 26 is fixed to the PCB 25 by four pins 260, and the top of the pressure sensor 22 is opposite to the middle hole 251. The pressure sensor 22 is provided with a pressure diaphragm 220, the pressure diaphragm 220 is in contact with the pressure receiving surface 214 at the tail end of the control rod 21, and when the control rod 21 moves up and down, the pressure diaphragm 220 is triggered by the pressure receiving surface 214, so that the pressure sensor 22 is triggered to work. The encoder 24 is arranged on the other side of the PCB 25, and the encoder 24 can be a rotary photoelectric encoder. The encoder 24 has a first input hole 240 in the middle, and the first input hole 240 has the same shape as the cross-section of the force transmission rod 213, so that the rotation of the control rod 21 can be transmitted to the encoder 24, and the force transmission rod 213 passes through the first input hole 240 and contacts the pressure sensor 22 at the other end. The flexible circuit board 250 is electrically coupled to the pressure sensor 22 and the encoder 24, and the flexible circuit board 250 transmits the pressure and encoder signals to the in-gauge controller.

In fig. 11, a structure of the driving wheel 3 is shown, which is formed in a cylindrical shape as a whole, and has an elliptical cross section, and a groove 30, a second input hole 31, a first process groove 32, and a second process groove 33 are formed in the driving wheel. The groove 30 cooperates with the mounting boss 10 on the bracket 1, and has a main function of saving space. A second input hole 31 is provided in the middle of the recess 30 for connection with an input handle 203 on the drive joint 20, which may be by means of a standing adhesive or other mechanical connection. The first process grooves 32 are equally spaced along the circumference of the rim of the drive wheel 3, the number of which is not limited in this embodiment. The second process groove 33 is positioned at the middle position of the other side of the driving wheel 3, and mainly has the functions of limiting and attractive appearance.

Fig. 12 shows a cross-sectional view of a horizontal crown in an embodiment, where the control part 2 and the driving wheel 3 form an angle with the horizon, which angle is in the range of 0 to 90 degrees, in this embodiment 20 degrees. In operation, the drive wheel 3 is subjected to two forces, one being a conventional wave action rotating the drive wheel 3 about an axis and the other being a downward or obliquely downward sloping depression. The first acting force effect is the same as the rotary action of the knob on the conventional crown, so that a rotary input is realized, but the principle adopted in the embodiment is different, and the scheme adopted in the embodiment is that the input rotation is transmitted to the driving joint 20 on the control part 2 through the driving wheel 3, and the driving joint 20 drives the control rod 21 to rotate through friction force, so that the encoder 24 is driven to work. When the driving wheel 3 is subjected to downward or obliquely downward pressure, the driving joint 20 rotates around the center of the spherical joint 200 and is perpendicular to the picture, and the axis passing through the center of the spherical joint 200 is used as a rotating shaft, and when the driving joint 20 rotates, the tail end of the control rod 21 is forced to slide upwards by the spherical surface 211, so that the triggering pressure sensor 22 is realized, the spring 28 is subjected to compression force in the process, and when the downward or obliquely downward pressure on the driving wheel 3 disappears, the control rod 21 is reset under the action of the spring 28, and the action of triggering the pressure sensor 22 once is completed.
