The following description is directed to the telescopic assembly 125 formed by two sets of X-shaped link assemblies.

Referring to fig. 7 to 12, the lever assembly 1252 includes a first link R1, a second link R2, a third link R3 and a fourth link R4. The four connecting rods are rod-shaped structures with the same length. The middle part of the first link R1 and the middle part of the third link R3 are hinged to form an X-shaped structure. The middle part of the second link R2 and the middle part of the fourth link R4 are hinged to form an X-shaped structure. One end of the first link R1 is hinged to one end of the second link R2. The other end of the first link R1 is provided with the second moving end P4, and the other end of the second link R2 is provided with the first moving end P3. That is, the free ends of the first link R1 and the second link R2 (the ends of the first link R1 and the second link R2 away from the hinged ends thereof) are the second moving end P4 and the first moving end P3, respectively, the second moving end P4 passes through the second stopper groove 1265 of the right frame 126 to be slidably connected with the right frame 126, and the first moving end P3 passes through the first stopper groove 1245 of the left frame 124 to be slidably connected with the left frame 124. One end of the third link R3 is hinged with one end of the fourth link R4. The other end of the third link R3 is disposed at the second fixed end P2. The other end of the fourth link R4 is disposed at the first fixed end P1. That is, free ends of the third link R3 and the fourth link R4 (ends of the third link R3 and the fourth link R4 away from their hinged ends) are a second fixed end P2 and a first fixed end P1, respectively, the first fixed end P1 is fixed to the first screw hole 1244 of the left frame 124 by screws, and the second fixed end P2 is fixed to the second screw hole 1264 of the right frame 126 by screws.

The elastic element 1254 is a coil spring, the elastic element 1254 is sleeved at the hinge joint of the first link R1 and the second link R2, two ends of the elastic element 1254 are respectively fixed to the first link R1 and the second link R2, the first link R1 and the second link R2 are switched between an open state and a closed state along with the extension and contraction of the lever assembly 1252, and in the process, the elastic element 1254 generates elastic deformation. Specifically, referring to fig. 7, 9 and 11, the first link R1 is provided with a slot 1255, the slot 1255 is located between the hinge of the first link R1 and the second link R2 and the middle of the first link R1, the slot 1255 is close to the middle of the first link R1, and one end of the elastic element 1254 is fixed in the slot 1255.

Further, referring to fig. 7 and 8, a step 1258 is disposed on a surface of the first link R1, which is attached to the third link R3, for limiting the rod assembly 1252 during the extension and retraction process. The step 1258 may be protrudingly disposed on a surface of the first link R1 or a surface of the third link R3, and the step 1258 is used to limit the position between the first link R1 and the third link R3 during extension and retraction. When the elastic element 1254 is in an elastically compressed state, the lever assembly 1252 is in a contracted state, at which time the third link R3 abuts against the step 1258 of the first link R1, restricting the first link R1 from continuing to move relative to the third link R3. Similarly, the surface of the fourth link R4, which abuts against the second link R2, is provided with a step 1258, and when the elastic element 1254 is in an elastically compressed state, the rod assembly 1252 is in a contracted state, at which time the second link R2 abuts against the step 1258 of the fourth link R4.

When the rod assembly 1252 is in the extended state, as shown in fig. 11 and 12, the first movable end P3 is located at an end of the first restraint slot 1245 remote from the first side wall 1242, the second movable end P4 is located at an end of the second restraint slot 1265 remote from the second side wall 1262, and the resilient element 1254 is in a free state. The direction of the stretching and contracting of the lever assembly 1252 is perpendicular to the moving direction of the first moving end P3 in the first limit groove 1245. In the process from contraction to extension, the position where the first link R1 and the second link R2 are hinged is not changed, the position where the third link R3 and the fourth link R4 are hinged moves toward the position near the hinge where the first link R1 and the second link R2 are hinged, the first fixed end P1 and the second fixed end P2 move leftward and rightward, respectively, the first moving end P3 moves leftward and toward the first fixed end P1, and the second moving end P4 moves rightward and toward the second fixed end P2. In the process from contraction to extension, the first fixed end P1 and the first movable end P3 are always in a relative positional relationship, and the displacement of the two moving in the left-right direction is the same; the second fixed end P2 and the second movable end P4 are always in a relative positional relationship, and the positions of movement in the left-right direction are the same.

Referring to fig. 19, the joystick 15 includes a head end 151 and a tail end 152 opposite to each other, and a bottom surface 153 and a mating surface 154 connected between the head end 151 and the tail end 152, wherein the bottom surface 153 and the mating surface 154 are opposite to each other. The mating surface 154 is provided with a protrusion 155, a groove 156 and a locking portion 157. Specifically, the groove 156 is provided between the protrusion 155 and the catch 157. The operating lever 15 is mounted in the second guide groove G2 with the projection 155 received in the opening G3, the projection 155 being smaller in size than the opening G3 such that the projection 155 is movable within the opening G3 to limit the travel of the operating lever 15 in the second guide groove G2. The latch 157 is adapted to engage the slot 1275 of the connecting piece 127. The latch 157 includes a second inclined surface 1572 facing into the first guide groove G1, the second inclined surface 1572 facing toward the frame assembly 12.

The head 151 of the operating lever 15 can extend out of the base 1422 from the open end G21 of the second guide groove G2 for user operation.

When the lever assembly 1252 is in the retracted state, the head end 151 of the operating lever 15 extends out of the open end G21 of the second guide groove G2 and is located outside the base 1422; the projection 155 of the lever 15 abuts against one end of the opening G3; the latch 157 engages the slot 1275 such that the tab 127 is retained and the pulling force exerted by the tab 127 on the lever assembly 1252 counteracts the resilient force of the resilient element 1254 in the lever assembly 1252.

When the frame assembly 12 needs to be stretched, the head end 151 of the operating lever 15 is pressed, the operating lever 15 moves in the second guide groove G2, so that the fastening portion 157 leaves the fastening groove 1275, at this time, the tensile force generated by the connecting piece 127 on the lever assembly 1252 is eliminated, and under the resilient force of the elastic element 1254 in the lever assembly 1252, the left frame 124 and the right frame 126 are driven to move to the left and right sides, and the connecting piece 127 is driven to move into the accommodating space 121 of the frame assembly 12. The head end 151 of the operating lever 15 is released, and the operating lever 15 is returned to the initial position by the elastic force of the elastic member 17 in the base 1422.

When it is desired to retract the frame assembly 12, the left frame 124 and the right frame 126 are pushed toward the middle, so that the left frame 124 and the right frame 126 move toward each other, and the connecting piece 127 is moved into the first guiding groove G1 of the base 1422, the first inclined surface 1276 of the connecting piece 127 abuts against the second inclined surface 1572 of the operating lever 15, and the operating lever 15 is forced to move toward the bottom end G22 of the second guiding groove G2. When the connecting piece 127 moves to the position where the locking portion 157 meets the locking slot 1275, the elastic element 17 in the second guide groove G2 recovers its deformation to drive the operating lever 15 to move toward the open end G21 of the second guide groove G2, so that the locking portion 157 moves into the locking slot 1275, thereby fixing the connecting piece 127.

During stretching and shrinking, the position of the bracket 142 remains unchanged.

When the winding drum 181 rotates, the limiting member 183 rotates along with the winding drum 181, and the connecting head 182 does not rotate along with the winding drum 181. When the reel 181 rotates, one end of the spring 184 rotates along with the limiting member 183, and the other end of the spring remains stationary relative to the connecting head 182, thereby generating a resilient force. The position-limiting member 183 is fixedly connected to the opposite end of the winding drum 181 by a snap (i.e. the step 1832 in the following embodiments).

In one embodiment, referring to fig. 25 and 26, the spool assembly 18 includes a spool 181, a connector 182, a stopper 183, a spring 184, and a fixing member 185.

The winding drum 181 is in a hollow cylindrical shape with two open ends, and the side of the winding drum 181 is provided with a seam 1812, and the seam 1812 is used for fixing the screen assembly 16. The connector 182 is installed to an opening at one end of the winding drum 181, the connector 182 is freely rotatably connected with the winding drum 181 in the circumferential direction (i.e. in the circumferential direction of the winding drum, there is no limit structure), and the rotation centers of the connector 182 and the winding drum 181 are both the axis of the winding drum 181. The fixing member 185 is used to connect the connecting head 182 to the second side wall 1262 of the right frame 126, and the fixing member 185 is matched with the right frame 126 and the connecting head 182 to realize the limit in the circumferential direction between the connecting head 182 and the right frame 126, i.e. the non-rotatable connection. The limiting member 183 is connected to an opening at the other end of the winding drum 181. The limiting member 183 is fixedly connected to the winding drum 181, and the two are connected in a limiting manner in the circumferential direction, i.e., the two cannot rotate relatively. The limiting member 183 is rotatably connected to the screw hole of the right frame 126 by a screw. The spring 184 is disposed in the winding drum 181, one end of the spring 184 is connected to the connection head 182, the other end of the spring 184 is connected to the limiting member 183, the spring 184 is in an axial compression state in the winding drum 181, and the elastic force of the spring 184 generates a thrust force on the connection head 182, so that the connection head 182 abuts against the right frame 126.

Referring to fig. 27, the position-limiting member 183 includes a base 1831, a step 1832 (corresponding to the above-mentioned buckle) formed on the base 1831, and a protrusion 1833.

In one embodiment the base 1831 is disk-shaped and the spool 181 is cylindrical. The circular truncated cone extends into the bobbin 181 and contacts the inner surface of the bobbin 181. When the limiting member 183 and the winding drum 181 rotate together, the protruding column 1833 drives one end of the spring 184 to rotate, and the other end of the spring 184 is fixed to the connector 182 and does not rotate, so that the spring 184 is twisted to generate elastic deformation. The elastic deformation generated by the torsion of the spring 184 can drive the reel 181 to automatically rotate. The base 1831 of the limiting member 183 is provided with a threaded hole, and the limiting member 183 is rotatably connected to the right frame 126 through the screw 186 and the threaded hole, as shown in fig. 31.

Flattened section 1862 passes through the threaded hole of right frame 126 and threaded section 1864 is locked into the threaded hole of base 1831, as shown in fig. 31. To fix the screw 186 to the base 1831, the flat 1862 of the screw 186 corresponds to the rotation shaft of the right frame 126 connected to the reel assembly 18, the surface of the flat 1862 is smooth, and the flat 1862 and the screw hole of the right frame 126 are in clearance fit and can rotate freely.

Referring to fig. 29, the connecting head 182 includes a substrate 1821 and a bump 1822, the substrate 1821 is provided with a slot 1823, the slot 1823 is a non-rotationally symmetric structure, for example, the slot 1823 may be a semi-circle, a polygon, or the like. The base plate 1821 covers the end face of the reel 181, and the protrusion 1822 extends into the reel 181. The protrusion 1822 is provided with a through hole 1824, and the through hole 1824 is used for fixing one end of the spring 184. The protrusion 1822 further includes a mating surface 18221, as shown in fig. 31, the mating surface 18221 is in contact with the inner surface of the winding drum 181, the mating surface 18221 is a cylindrical surface, and the contact between the mating surface 18221 and the inner surface of the winding drum 181 realizes the position limitation between the connecting head 182 and the winding drum 181 in the radial direction, so that a smooth rotational connection relationship is provided therebetween, and the connecting head 182 and the winding drum 181 are not shaken in the radial direction. The radial direction refers to a direction perpendicular to the axial direction of the bobbin 181.

The connector 182 is located inside the right frame 126. Referring to FIG. 30, the fixing member 185 includes a fixing head 1851 and an insertion rod 1852, and the insertion rod 1852 has a shape corresponding to the shape of the slot 1823 of the base 1821 of the connecting head 182. The insertion rod 1852 and the slot 1823 are both non-rotationally symmetrical, and the insertion rod 1852 and the slot 1823 cooperate to fixedly connect the connecting head 182 to the fixing element 185. In one embodiment, plunger 1852 is a cylindrical surface that is partially cut away, i.e., it is comprised of a circular arc surface and a flat surface. In other embodiments, the interface of the plunger 1852 can be triangular or square or other irregular shapes, so long as the plunger 1852 is secured against rotation in the slot 1823. The mounting head 1851 is also non-rotationally symmetric, e.g., the mounting head is square.

Referring to fig. 31, the sidewall of the right frame 126 is provided with a groove matching with the fixing head 1851 of the fixing member 185, for example: the fixed head 1851 is contained in the square groove, and the fixed head and the square groove are connected in a non-transferable manner. The end surface of the fixing head 1851 is provided with an opening 1853. The connection head 182 and the winding drum 181 are not fixed, and the winding drum 181 does not drive the connection head 182 to rotate when rotating.

When it is necessary to adjust the torsion force of the spring 184 in the winding drum 181 in the circumferential direction, the fixing member 185 may be partially pulled out from the square groove of the right frame 126, and then the fixing head 1851 may be rotated by inserting a tool into the opening 1853 of the fixing head 1851 of the fixing member 185. Since the plane of the insert 1852 of the fixing element 185 abuts against the plane of the slot 1823 of the connecting head 182, the connecting head 182 is driven to rotate together, and the connecting head 182 drives one end of the spring 184 to rotate through the protrusion 1822, so that the spring 184 is twisted, and the torsion force is changed. Therefore, since the square groove of the right frame 126 is a through groove provided on the second side wall 1262, the torsion force of the spring 184 in the reel 181 can be adjusted outside the frame assembly 12 without disassembling the dial 10. After the adjustment, the fixing member 185 is pushed into the square groove.

When the dial 10 is stretched and unfolded, the reel 181 rotates to drive the spring 184 in the reel 181 to generate torsional deformation under the pulling of the screen assembly 16, so as to generate resilience. When the user promotes left and right frame 124, 126 for dial plate 10 contracts, under the effect of twisting elasticity, reel 181 will rotate, drive screen subassembly 16 rolling on reel 181, consequently, this application can realize the effect of automatic rolling screen subassembly 16. The elastic force of the torsional deformation of the spring 184 in the reel 181 is smaller than the elastic force of the elastic member 1254 of the elastic link assembly 1252 in the frame assembly 12, so as to prevent the dial 10 from being automatically contracted by the spring 184 in the reel 181 after being stretched.

Each of the receiving grooves receives therein a rack of the first tooth portion 1444 and a rack of the second tooth portion 1464. In one embodiment, the width of the gap between two adjacent ribs 14252 is equal to the width of one rack 1445 of the first tooth 1444 plus the width of one rack 1465 of the second tooth 1464. One of the ribs 14252 has a width equal to a width of one rack 1445 of the first tooth portion 1444 or a width of one rack 1465 of the second tooth portion 1464. Specifically, the width of the receiving groove is greater than or equal to the width of one rack 1445 of the first tooth portion 1444 or the width of one rack 1465 of the second tooth portion 1464, and is smaller than the sum of the widths of the one rack 1445 of the first tooth portion 1444 and the one rack 1465 of the second tooth portion 1464.

In the left and right support frames 144, 146, the width of the gap between the adjacent racks is twice as large as the width of the racks, and the width of the rib 14252 on the plate 1425 of the frame body 1421 is the same as the width of the racks 1445, 1465. Referring to fig. 34, when the left and right supporting frames 144, 146 move to close along with the left and right frames 124, 126, the rack 1465 of the right supporting frame 146 and the rack 1445 of the left supporting frame 144 are completely received in the gap between the ribs 14252 of the frame body 1421, so that the racks 1445, 1465 of the left and right supporting frames 144, 146 and the ribs 14252 of the frame body 1421 form a flat plane together, and the touch feeling of the screen assembly 16 on the flat plane is ensured.

Referring to fig. 35, when the left and right supporting frames 144, 146 move to open along with the left and right frames 124, 126, the rack 1465 of the right supporting frame 146 and the rack 1445 of the left supporting frame 144 are only partially received in the gap (i.e., the receiving slot) between the ribs 14252 of the frame 1421, so that the racks 1445, 1465 of the left and right supporting frames 144, 146 and the ribs 14252 of the frame 1421 together form a discontinuous plane, i.e., adjacent supporting surfaces (referring to the surfaces of the racks 1445, 1465 and the ribs 14252 for supporting the screen assembly 16) are separated by the receiving slot. However, in the transverse direction (i.e. from left to right), each rib 14252 is continuously distributed with the rack 1445 of the adjacent left support frame 144 and the rack 1465 of the adjacent right support frame 146; the spacing between each adjacent rack 1445, 1465 and each adjacent rib 14252 in the longitudinal direction may still provide good support for the screen assembly. In fact, because the width of a human finger is much greater than the spacing between ribs 14252 and the spacing between racks 1445 and 1465, the feel of a touch on screen assembly 16 is not significantly affected.

Referring to fig. 36, a tray 147 is fixed in the left support frame 144. The tray 147 is located between the first tooth 1444 and the first bottom plate 1443 for supporting the positioning circuit board 148, and the bottom of the tray 147 is attached to the first bottom plate 1443 of the left supporting frame 144. The front and back sides of the circuit board 148 are provided with electronics, such as controllers, memory, etc., for controlling the screen assembly 16. In other embodiments, the circuit board 148 can be directly fixed on the first bottom plate 1443. Specifically, the tray 147 is screwed to the inner surface of the first side plate 1242 of the left frame 124 together with the first side plate 1442 of the left support frame 144. Hooks 1472 are formed on the tray 147, and the hooks 1472 are used for positioning the circuit board 148 on the tray 147 in a suspended manner, so that the front and back sides of the circuit board 148 have space for accommodating electronic devices.

Referring to fig. 37, a first bottom plate 1443 of the left support bracket 144 and a first bottom wall 1241 of the left frame 124 are spaced apart from each other to form a space for accommodating the telescopic assembly 125 (the rod assembly 1252 in the present embodiment). The right support bracket 146 is positioned above the spool assembly 18. The spool assembly 18 is sandwiched between the right support bracket 146 and the lever assembly 1252. Second base 1461 of right support frame 146 forms a gap with right frame 126, so that screen assembly 16 can be inserted into right frame 126 through the gap and wound on reel 181.

The present application also provides another support assembly 14 configuration. As shown in fig. 38 to 42. In this embodiment, the supporting component 14 is different from the supporting component 14 of the previous embodiment in that: the rack 1421 of the rack 142 has a structure matching with the tooth structure of the left and right supports 146. In the supporting assembly 14 of the previous embodiment, the ribs 14252 on the bracket 142 form receiving slots, each receiving the racks of the left and right supporting frames 144, 146, and one receiving slot receives two racks. In the supporting assembly 14 of the present embodiment, the surface of the plate 1425 of the frame 1421 of the bracket 142 is not provided with the rib 14252, but the surface of the plate 1425 is coplanar with the surfaces of the teeth of the left and right supporting frames 144, 146, meanwhile, the surface of the plate 1425 is provided with a plurality of receiving slots 14253, the distribution of the receiving slots 14253 is denser than the distribution of the receiving slots 14253 on the frame 1421 of the previous embodiment, a supporting strip for supporting the screen assembly 16 is formed between two adjacent receiving slots 14253, and each receiving slot 14253 only receives one rack 1445 of the left supporting frame 144 or one rack 1465 of the right supporting frame 146, that is, one receiving slot 14253 receives one rack. The racks 1445 of the left support frame 144 and the racks 1465 of the right support frame 146 are alternately spaced from each other and are engaged with the receiving grooves 14253, that is, the receiving grooves 14253 are aligned in a row, the number of the receiving grooves 14253 is equal to the sum of the number of the racks 1445 of the first tooth portion 1444 and the number of the racks 1465 of the second tooth portion 1464, and the racks 1445 of the left support frame 144 and the racks 1465 of the right support frame 146 are respectively received in two adjacent receiving grooves 14253.

Referring to fig. 40, when the left and right supporting frames 144, 146 are moved to open along with the left and right frames 124, 126, the adjacent supporting surfaces (referring to the surfaces of the racks 1445, 1465 for supporting the screen assembly 16 and the surfaces of the supporting bars formed between the adjacent two receiving slots 14253 for supporting the screen assembly 16) are continuous near the edge of the supporting frame 142.

Referring to fig. 41, the rack 1445, 1465 of the support assembly 14 of the present embodiment has a substantially circular cross-section with its top surface cut away to form a flat support surface for better attachment to the screen assembly 16. The cross-section of the receiving slot 14253 of the bracket 142 is also circular with a truncated top to receive the racks 1445, 1465.

Since the racks 1445, 1465 of the left and right support frames 144, 146 are configured to be narrow at the top and wide at the bottom, and the cross section of the receiving groove 14253 is also narrow at the bottom, that is, the opening of the receiving groove 14253 in the direction perpendicular to the surface of the plate 1425 of the bracket 142 (i.e., the direction perpendicular to the screen assembly 16) is smaller than the size of the inner space thereof, so that the racks 1445, 1465 are vertically limited by the receiving groove 14253 by the blocking of the inner wall of the receiving groove 14253 in the receiving groove 14253, and any position of the racks 1445, 1465 will not be separated from the receiving groove 14253, and therefore, the end of the racks 1445, 1465 will not be tilted, and the flatness of the screen assembly 16 can be further ensured.

Further, the rack 1445 of the left support bracket 144 and the first base 1441 may be integrally formed, or may be a two-piece structure, i.e., manufactured separately and assembled together. The connection between the rack 1465 of the right support frame 146 and the second base 1461 can be formed integrally or in two pieces.

The application also discloses a triggering device, which is used for selectively triggering the working area of the screen assembly 16 according to the display size of the screen assembly 16, so as to realize the automatic switching effect of the working area of the screen assembly 16. Because the dial 10 is retractable and expandable, when the dial 10 is retracted, the trigger device triggers the screen assembly 16 to work only in the exposed partial area, and the retracted part does not need to work; when the dial 10 is unfolded, the exposed area of the screen assembly 16 is increased, and the triggering device triggers all exposed areas of the screen assembly 16 to work.

The trigger device comprises a controller 1482, a screen assembly 16, a telescopic supporting assembly 14 for supporting the screen assembly 16, and a driving assembly for driving the supporting assembly 14, wherein the driving assembly is provided with a first contact, the supporting assembly 14 is provided with a second contact which can move relative to the first contact, in the process of extending or retracting the supporting assembly 14, the first contact and the second contact move relatively to be in a contact or separated state, and the controller 1482 judges that the supporting assembly 14 is in a retracted state or an extended state according to the contact state or the separated state of the first contact and the second contact, so as to control the display of the screen assembly 16.

Referring to fig. 42, 43, 44, 45 and 46, the driving assembly corresponds to the lever assembly 1252 in the present embodiment, and the first contact is disposed on the lever assembly 1252. The second contact is arranged on the spring plate 19. The elastic sheet 19 is fixedly connected with the supporting component 14 and can be regarded as a component of the supporting component 14. In one embodiment, the support assembly 14 extends and retracts in a first direction and the first contact moves relative to the second contact in a second direction, the first direction being different from the second direction. In a preferred embodiment, the first direction is perpendicular to the second direction. When the supporting member 14 extends and retracts in the first direction, the first contact and the second contact move along the first direction.

The driving assembly comprises a first link R1 and a second link R2 hinged with each other, and when the supporting assembly 14 extends or contracts, the first link R1 and the second link R2 move relatively. In one embodiment, the first contact is disposed on the second link R2, the second link R2 is made of conductive material, and the second link R2 is electrically connected to the controller 1482. When the first contact is in contact with the second contact, the second link R2 forms a current path with the controller 1482; when the first contact is separated from the second contact, the second link R2 is disconnected from the current path formed by the controller 1482.

Referring to fig. 46, specifically, a first contact is grounded, a second contact is electrically connected to a terminal of a controller 1482, the controller 1482 is further electrically connected to a resistor (i.e., a pull-up resistor 1483 in the embodiment shown in fig. 46), and when the first contact is contacted to the second contact, a low voltage is present at the terminal of the controller 1482; when the first contact is separated from the second contact, the resistor (i.e., pull-up resistor 1483) generates a high level signal and inputs it to a terminal of the controller 1482.

In the present embodiment, the trigger operation is realized by one link (for example, the second link R2) of the lever assembly 1252 engaging with the resilient piece 19. The rod assembly 1252 can extend and retract to drive the frame assembly 12 for carrying the screen assembly 16 to extend and retract, the elastic sheet 19 is fixedly connected with the left frame 124 in the frame assembly 12, the rod assembly 1252 comprises a convex column 194, and in the process of extending and retracting the rod assembly 1252, the convex column 194 generates displacement relative to the elastic sheet 19. In this embodiment, the rod assembly 1252 has a boss 194 at the first moving end P3 extending toward the bottom of the left support frame 144. Specifically, the boss 194 is provided at one end of the second link R2. That is, the first contact includes the boss 194 formed on the second link R2, and the second contact includes the spring 19.

Specifically, the support assembly 14 includes a tray 147, the controller 1482 is mounted above the tray 147, and the second contacts are secured below the tray 147. The bottom of the left support bracket 144 (i.e., the first bottom plate 1443) is provided with a through slot exposing the bottom of the tray 147. The spring plate 19 includes a fixing plate 192 and a pressing plate 193. The fixing plate 192 is fixed in the through groove by a screw. The tray 147 and the circuit board 148 are located on a side of the first bottom plate 1443 away from the first bottom wall 1241 of the left frame 124. The fixing pieces 192 are electrically connected to the electronic devices on the circuit board 148 provided in the tray 147. The pressing piece 193 protrudes and extends from the fixing piece 192 toward the rod assembly 1252. In one embodiment, the pressing piece 193 is a bent structure and is integrally formed with the fixing piece 192, and the pressing piece 193 may be perpendicular to the fixing piece 192. The pressing piece 193 is used to abut the lever assembly 1252.

Referring specifically to fig. 43 and 45, post 194 is connected to ground on circuit board 148 (referring to circuit board 148 in left support bracket 144 of support assembly 14) via wire 195 which is connected to lever assembly 1252. Post 194 is therefore grounded. In one embodiment, post 194 and post assembly 1252 are both conductive materials, such as metal rods, and post assembly 1252 is electrically connected to ground of circuit board 148 by wire 195. In another embodiment, rod assembly 1252 is an insulating material, post 194 is a conductive material, and post 194 is electrically connected to the circuit board ground by a wire.

As shown in fig. 43 and 45, the resilient piece 19 is electrically connected to the controller 1482 on the circuit board 148 through a wire 196.

The convex column 194, the elastic sheet 19 and the electronic components on the circuit board 148 form a sensing circuit, and the sensing circuit is used for sensing the position relationship between the convex column 194 and the elastic sheet 19 and generating signals. A controller 1482 on the circuit board 148 is configured to receive signals transmitted by the sensing circuitry and control the display of the screen assembly 16.

When the dial 10 is contracted, the first moving end P3 is located at one end of the first limiting groove 1245 close to the first side wall 1242 of the left frame 124, the protruding pillar 194 contacts or abuts against the abutting piece 193, and the sensing circuit forms a closed current loop through the electrical connection between the elastic piece 19 and the lever assembly 1252, so as to generate a signal. Controller 1482 on circuit board 148 receives the signal to determine that dial 10 is in the retracted state and further controller 1482 controls screen assembly 16 to operate only in the exposed area.

When the dial 10 is unfolded, the first moving end P3 moves to the end of the first limiting groove 1245 away from the first side wall 1242, and the protruding pillar 194 is separated from the pressing piece 193, so that the current loop of the sensing circuit is disconnected. Controller 1482 is unable to receive a signal and at this point controller 1482 determines that dial 10 is in the extended state and further controls the operation of all exposed areas of screen assembly 16.

In detail, referring to fig. 46, a circuit configuration of the triggering device in an embodiment includes a controller 1482 and a pull-up resistor 1483, the controller 1482 is electrically connected to the elastic piece 19, a switch structure is formed between the elastic piece 19 and the stud 194, when the elastic piece 19 abuts against the stud 194, the elastic piece 19 is electrically connected to a ground terminal of the stud 194, and a voltage at a terminal of the controller 1482 is 0, which is represented as a low level. The controller 1482 receives the low signal and determines that the panel assembly 16 is in the retracted state. When the spring plate 19 is separated from the protruding column 194, the spring plate 19 is disconnected from the ground, and a high level generated by the pull-up resistor 1483 is input to the terminal of the controller 1482. The controller 1482 receives the high signal and determines that the panel assembly 16 is in the extended state.

The triggering structure of the application, because the automatic switching function of the screen assembly 16 is realized by adopting the telescopic structure (i.e. the rod assembly 1252), does not need to add a complex switching device (only adding a simple-structure elastic sheet 19) in the dial 10, and does not additionally occupy too much space in the dial 10, so that the dial 10 has a more compact structure, and is beneficial to saving the internal space of the dial 10.

In one embodiment, the left frame 124, the right frame 126, the left support frame 144, the right support frame 146, and the like of the dial 10 are made of metal materials, so that if the wireless communication module is disposed in the dial 10, the wireless communication module will not work well due to the metal shielding effect. Thus, the present application further designs unique antenna structures.

Referring to fig. 47, the antenna structure includes a wireless communication module (not shown) and an antenna module, and the wireless communication module is disposed on a circuit board 148 inside the dial 10. The controller 1482 is electrically connected to the FPC11, the FPC11 protrudes through the support assembly 14 and is partially located outside the dial 10, and the portion of the FPC11 located outside the dial 10 is attached to the antenna module. The antenna module is disposed on the FPC11 protruding out of the dial 10 and is electrically connected to the wireless communication module by a wire.

The portion of FPC11 located outside dial 10 is also provided with keys 112, and keys 112 and antenna module are located on opposite sides of FPC11, respectively. Specifically, a reinforcing structure 114 is provided on the bottom surface of the FPC11, as shown in fig. 47, the reinforcing structure 114 includes two independent parts, and the reinforcing structure 114 is made of a rigid material and can enhance the hardness of the FPC11, so that the FPC11 protruding from the dial 10 can be connected to electronic devices such as keys and connectors in a flat manner. The provision of the reinforcing structure 114 is beneficial to enhance the stability and the service life of the keys 112 and the connector 113 on the FCP. The reinforcing structure 114 disposed on the bottom surface of the FPC11 may be a metal sheet, and further, the reinforcing structure 114 may be an antenna module, that is, a radiator of an antenna, and the antenna module is electrically connected to the wireless communication module through a wire to receive and transmit wireless signals. The antenna module may be configured as an inverted-F antenna or other type of antenna. In particular, the reinforcing structure 114 on the left side and the reinforcing structure 114 on the right side are isolated from each other by a trench. The area of the reinforcing structure 114 on the left side is smaller than the area of the reinforcing structure 114 on the right side. Only the left reinforcing structure 114 serves as an antenna module, and the right reinforcing structure 114 serves as support reinforcement only.

The FPC11 extending out of the portion of the dial 10 is secured to the base 1422 of the support 142, the bottom surface of the FPC11 is attached to the base 1422, and the connectors 113 and buttons 112 on the front surface of the FPC11 are exposed for engagement with associated features on the wristband 20.
