[0003] Currently, when users use brackets to fix mobile phones, on-board screens and other mobile terminal displays when riding electric power-assisted bicycles, in order to adjust the best viewing angle, especially during riding, it is usually necessary to adjust the angle of the terminal display screen. However, the adjustment is not convenient during riding, and there is even a situation where one hand controls the power-assisted bicycle and the other hand adjusts the angle of the terminal display screen. Not only can the bicycle not be operated normally, but there are also certain safety hazards. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides a handle structure for an electric power-assisted bicycle to solve the problem that a mobile phone holder on a power-assisted bicycle is inconvenient to adjust.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A handlebar structure of an electric power-assisted bicycle, comprising:

[0006] A bicycle handlebar, wherein the bicycle handlebar is a straight handlebar, and the straight handlebar comprises a first sleeve, a second sleeve and a middle sleeve, wherein the first sleeve and the second sleeve are respectively arranged at two ends of the middle sleeve;

[0007] Hand grip 1 and hand grip 2, which are respectively arranged at one end of the first sleeve and the second sleeve, the hand grip 1 includes a grip handle 1 and a hand dial wheel 1, one end of the hand dial wheel 1 is inserted into the first sleeve or the second sleeve and the other end is inserted into the hand grip 1, the hand grip 2 includes a grip handle 2 and a hand dial wheel 2, one end of the hand dial wheel 2 is inserted into the first sleeve or the second sleeve and the other end is inserted into the hand grip 2;

[0008] The bracket adjustment component is arranged on the middle sleeve, and the bracket adjustment component includes a first direction adjustment part, a second direction adjustment part connected to the first direction adjustment part, and a suspension shaft horizontally arranged on the first direction adjustment part and loaded with a mobile terminal. The first direction adjustment part is connected to the hand dial wheel 1 or the hand dial wheel 2. When the first direction adjustment part is connected to the hand dial wheel 1, the hand dial wheel 1 is turned to rotate in the first sleeve or the second sleeve and can drive the first direction adjustment part to drive the suspension shaft to rotate axially with its axis as the axis. When the first direction adjustment part is connected to the hand dial wheel 2, The toggle hand wheel 2 rotates in the first sleeve or the second sleeve and can transmit the first direction adjustment part to drive the suspension shaft to rotate axially with its axis as the axis; the second direction adjustment part is connected to the hand wheel 1 or the hand wheel 2. When the second direction adjustment part is connected to the hand wheel 1, the toggle hand wheel 1 rotates in the first sleeve or the second sleeve and can transmit the second direction adjustment part to drive the suspension shaft to rotate horizontally. When the second direction adjustment part is connected to the hand wheel 2, the toggle hand wheel 2 rotates in the first sleeve or the second sleeve and can transmit the second direction adjustment part to drive the suspension shaft to rotate horizontally.

[0009] The beneficial effects of the present invention are:

[0010] 1) A hand wheel 1 and a hand wheel 2 are inserted into the hand grips at both ends of the handlebars of the electric power-assisted bicycle. When the hands are held on the hand grips 1 and 2 during riding, the hand wheel 1 and the hand wheel 2 are rotated by turning the hands, which transmits power to the first direction adjustment part and the second direction adjustment part. The power transmitted to the first direction adjustment part can drive the suspension shaft to rotate axially with its axis as the axis, and the power transmitted to the second direction adjustment part can drive the suspension shaft to rotate horizontally, thereby driving the mobile terminal loaded on the suspension shaft to rotate axially with its axis as the axis and driving the mobile terminal loaded on the suspension shaft to rotate horizontally, thereby realizing the adjustment of various directions and angles of the mobile terminal loaded on the bicycle.

[0011] 2) In addition, the device can adjust the angle of the mobile terminal display screen on the bicycle at multiple angles without removing both hands from the handlebars and operating the bicycle normally while riding. This not only facilitates viewing the content of the mobile terminal display screen, but also avoids the situation in which the rider cannot concentrate on riding due to one-handed operation of the bicycle and the other hand adjusting the angle of the terminal display screen during riding, resulting in loss of normal control of the bicycle, which in turn causes traffic accidents, posing certain safety hazards.

[0012] Based on the above technical solution, the present invention can also be improved as follows.

[0013] Further, the first direction adjustment unit includes:

[0014] A worm gear set 1 is arranged in the middle sleeve, one end of the worm gear 1 of the worm gear set 1 is coaxially fixed on the hand-turning wheel 1 or the hand-turning wheel 2, and the worm gear 1 is rotatably connected to the inside of the middle sleeve through a rotating shaft;

[0015] A column, wherein the column is coaxially fixed to the top of the worm wheel of the worm gear set;

[0016] A nut sleeve, the nut sleeve is coaxially fixed on the top of the column;

[0017] A vertical pipe, the vertical pipe is arranged on the circumferential outer wall of the column and the nut sleeve through a bearing sleeve;

[0018] A screw rod, the screw rod is screwed into the nut sleeve through a thread;

[0019] A regulating box, wherein the regulating box is fixed on the top of the riser;

[0020] A linkage assembly, wherein the linkage assembly is arranged on the top of the screw rod;

[0021] A gear rack set, the gear rack set is arranged on the linkage assembly and is located in the adjustment box, one end of the suspension shaft passes through the gear of the gear rack set and is rotatably connected in the adjustment box through the rotating shaft, and the other end passes through the adjustment box and extends outside the cavity, one end of the rack of the gear rack set extends into the cavity of the adjustment box, and the linkage assembly is used for the riser to rotate with the gear rack set and follow the rotation, and the worm gear 1 rotates without being linked to the gear rack set;

[0022] A limit piece, wherein the limit piece is arranged between the rack of the gear and rack set and the adjusting box, and is used for limiting the axial rotation of the screw screwed in the nut sleeve by the rack of the gear and rack set through non-coupling with the nut sleeve and linear sliding in the inner wall of the adjusting box when the worm gear drives the screw to rotate, so that the screw can drive the rack to move along its axis, and the rack drives the suspension shaft to rotate about its axis.

[0023] The beneficial effect of adopting the above-mentioned further scheme is that when one end of the worm is coaxially fixed on the hand dial wheel, when the hand dial wheel rotates, it can drive the worm to rotate, and due to the meshing relationship between the worm wheel and the worm, it can also drive the worm wheel to rotate axially, and the column and the nut sleeve are coaxially fixed on the top of the worm wheel, thereby driving the column and the nut sleeve to rotate. In addition, the linkage component is used to make the worm wheel rotate without being linked to the gear rack group to follow the rotation, and when the worm wheel drives the lead screw to rotate through the limit piece, the rack of the gear rack group is not linked with the nut sleeve and linearly slides in the inner wall of the adjustment box to limit the axial rotation of the lead screw screwed in the nut sleeve, so that the lead screw can drive the rack to move along its axis, and due to the meshing relationship between the rack and the gear, the gear drives the suspension shaft to rotate with the axis of the suspension shaft as the axis, so that the mobile terminal loaded on the suspension shaft can rotate with the axis of the suspension shaft as the axis, thereby adjusting the tilt angle of the mobile terminal.

[0024] Further, the second direction adjustment unit includes:

[0025] A gear set, the gear set comprising two gears 1 and 2 arranged longitudinally and meshing with each other, the gears being coaxially fixed on the hand-turning wheel 1 or the hand-turning wheel 2;

[0026] A worm gear set 2, wherein the worm gear 2 of the worm gear set 2 is coaxially fixed on the gear 2, the worm gear 2 of the worm gear set 2 is coaxially sleeved on the outside of the riser, and the worm gear 2 is used to drive the riser and the suspension shaft on the regulating box to rotate around the axis of the riser.

[0027] The beneficial effect of adopting the above further scheme is that when the gears are coaxially fixed on the hand dial wheel 2, when the hand dial wheel 2 rotates, it can drive the gears to rotate together. Due to the meshing relationship between gear 1 and gear 2 in the gear set, gear 1 drives gear 2 to rotate. Gear 2 is coaxially fixed with worm gear 2, and therefore, it can drive worm gear 2 to rotate. Due to the meshing relationship between worm gear 2 and worm gear 2, worm gear 2 drives worm gear 2 to rotate, and worm gear 2 is coaxially sleeved on the outside of the vertical pipe. Worm gear 2 drives the vertical pipe to rotate. An adjustment box is provided on the top of the vertical pipe, and the vertical pipe drives the adjustment box to rotate. In addition, a linkage component is used to make the vertical pipe linked to the gear rack group to follow the rotation when it rotates. At this moment, the rotating adjustment box links the gear rack group and the suspension shaft in the adjustment box to rotate around the axis of the vertical pipe, so that the mobile terminal loaded on the suspension shaft can be rotated from a horizontal landscape screen to a horizontal portrait screen.

[0028] Furthermore, the linkage assembly includes an inner gear ring, a rotating column and a clamping piece, wherein the inner gear ring is coaxially fixed to the top of the screw rod, the rotating column is fixed to the bottom of the rack of the gear rack set and is coaxially located in the inner gear ring, and the clamping piece moves in the rotating column.

[0029] Furthermore, the engaging part includes a movable groove, an electromagnetic block, a return spring and an engaging tooth block, the opening of the movable groove is toward the radial direction of its rotating block and is opened on the circumferential side wall of the rotating block, the electromagnetic block is fixed to the inner wall of the movable groove, the return spring is fixed to one side of the electromagnetic block, the engaging tooth block is fixed to one side of the return spring, and the engaging tooth block is a magnet and repel each other with the magnetic poles of the energized electromagnetic block.

[0030] Furthermore, the limiting member includes a slide block that matches the slide groove and slides in the slide groove, the slide groove is opened on one side of the rack of the gear rack set, and the slide block is fixed on the inner wall of the adjustment box.

[0031] The beneficial effect of adopting the above further scheme is that by energizing the electromagnetic block, the electromagnetic block generates magnetic poles that repel each other with the engaging tooth block, so that the engaging tooth block in the movable groove can be pushed out of the movable groove, and at the same time, the reset spring is stretched and stuck in the inner teeth of the inner gear ring. When the worm gear rotates, the column and the nut sleeve are driven to rotate. In addition, since the slider in the adjustment box slides in the slide groove in the rack of the gear rack group and the rotating column under the rack is stuck in the inner gear ring through the engaging tooth block, and the gear ring is coaxially fixed to the top of the screw rod, the screw rod cannot rotate with the nut sleeve. Therefore, the spiral connection between the screw rod and the nut sleeve is utilized to make the screw rod displace along its axis, and also drive the rack to displace along the axis of the screw rod, so as to realize the linkage relationship that the rack of the gear rack group does not rotate with the standpipe.

[0032] When the circuit of the electromagnetic block is closed, the electromagnetic block loses the magnetic poles that repel each other with the engaging tooth block. At this time, due to the elastic force of the stretched return spring, the engaging tooth block stuck on the inner gear ring can be pulled back into the movable groove again. When the vertical pipe rotates, the vertical pipe drives the adjusting box to rotate, and the rotating adjusting box links the gear rack group and the suspension shaft in the adjusting box to rotate around the axis of the vertical pipe. At this moment, the rotating column under the rack of the gear rack group has no effect on the inner gear ring through the engaging tooth block. Therefore, the rack rotated by the linkage of the adjusting box will not cause the screw to rotate, thereby realizing the linkage gear rack group to follow the rotation.

[0033] Furthermore, a mobile phone holder is sleeved on the outer circumference of the suspension shaft.

[0034] The beneficial effect of adopting the above further solution is that it is convenient to fix the mobile terminal.

[0035] Furthermore, the hand grip one also includes a hand shift sleeve one, the hand shift sleeve one has a conical cross-section and is fixed to the circumferential outer wall of one end of the hand shift wheel one, and is located between the hand shift wheel one and the handle one, wherein the end of the hand shift sleeve one with a larger diameter faces the handle one, and the hand grip two also includes a hand shift sleeve two, the hand shift sleeve two has a conical cross-section and is fixed to the circumferential outer wall of one end of the hand shift wheel two, and is located between the hand shift wheel two and the handle two, wherein the end of the hand shift sleeve two with a larger diameter faces the handle two.

[0036] The beneficial effect of adopting the above further solution is that the contact area between the hand and the hand wheel is increased, thereby making it easier for the rider to rotate the hand wheel by holding the hand on the handlebar, thereby achieving convenient adjustment of the direction and angle of the mobile terminal.

[0037] Furthermore, a locking assembly is provided between handle 1 and the first sleeve and between handle 2 and the second sleeve, and the locking assembly is used to fasten handle 1 to the first sleeve and to fasten handle 2 to the second sleeve. The locking assembly includes an L-shaped insertion rod and a locking ring. The insertion rod is fixed at the bottom of handle 1 and handle 2 and one end of the insertion rod extends into the locking ring. The locking ring is fixed at the bottom of the first sleeve and the second sleeve and corresponds to the insertion rod.

[0038] The beneficial effect of adopting the above-mentioned further scheme is that, by utilizing the connection relationship in which the inserted rod is fixed at the bottom of the handle one and the handle two and one end extends into the locking ring, and the inserted rod is fixed at the bottom of the handle and the handle two and one end extends into the locking ring, the handle one is fastened to the first sleeve and the handle two is fastened to the second sleeve, thereby limiting the rotation ability of the handle one and the handle two, and thus making it convenient for the rider to hold the handle one and the handle two while riding, and they will not rotate.

[0039] Furthermore, a locking assembly is provided between handle 1 and the second sleeve and between handle 2 and the first sleeve, and the locking assembly is used to fasten handle 1 to the second sleeve and to fasten handle 2 to the first sleeve. The locking assembly includes an L-shaped insertion rod and a locking ring. The insertion rod is fixed at the bottom of handle 1 and handle 2 and one end of the insertion rod extends into the locking ring. The locking ring is fixed at the bottom of the first sleeve and the second sleeve and corresponds to the insertion rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0051] Power-assisted bicycle is a new type of two-wheeled vehicle, a type of bicycle. It uses batteries as an auxiliary power source, is equipped with a motor, and has a power assist system. It is a new type of transportation tool that can integrate human riding and motor assistance.

[0052] At present, when users use a bracket to fix mobile phones and mobile terminal display screens such as vehicle-mounted screens when riding electric power-assisted bicycles, in order to adjust the best viewing angle, especially during riding, it is usually necessary to adjust the angle of the terminal display screen, such as switching between the horizontal screen angle and the vertical screen angle of the mobile phone in a horizontal state, and adjusting the tilt angle of the mobile phone in the vertical screen angle. However, the adjustment is not convenient enough during riding, and it is even possible to operate the power-assisted bicycle with one hand and adjust the placement angle of the mobile phone with the other hand. Not only can the bicycle not be operated normally, but there are also certain safety hazards. In this regard, the inventor has proposed an electric power-assisted bicycle handlebar structure to solve the above problems.

The hand grip 1 200 includes a grip 1 201 and a hand dial wheel 1 202. One end of the hand dial wheel 1 202 is inserted into the first sleeve 101 or the second sleeve 102 and the other end is inserted into the hand grip 1 201. The hand grip 2 300 includes a grip 2 301 and a hand dial wheel 2 302. One end of the hand dial wheel 2 302 is inserted into the first sleeve 101 or the second sleeve 102 and the other end is inserted into the hand grip 2 301.

[0057] The bracket adjustment component 400 is arranged on the middle sleeve 103, and the bracket adjustment component 400 includes a first direction adjustment part 410, a second direction adjustment part 420 connected to the first direction adjustment part 410, and a suspension shaft 430 horizontally arranged on the first direction adjustment part 410 and loaded with a mobile terminal (the mobile terminal includes a mobile phone, a tablet computer, and a car screen, etc.), the first direction adjustment part 410 is connected to the hand dial wheel 1 202 or the hand dial wheel 2 302, when the first direction adjustment part 410 is connected to the hand dial wheel 1 202, the hand dial wheel 1 202 is turned to rotate in the first sleeve 101 or the second sleeve 102 and can transmit the first direction adjustment part 410 to drive the suspension shaft 430 with its The axis is used as the axis for axial rotation. When the first direction adjustment part 410 is connected to the hand-push wheel 2 302, the hand-push wheel 2 302 is turned to rotate in the first sleeve 101 or the second sleeve 102 and can transmit the first direction adjustment part 410 to drive the suspension shaft 430 to axially rotate with its axis as the axis; the second direction adjustment part 420 is connected to the hand-push wheel 1 202 or the hand-push wheel 2 302. When the second direction adjustment part 420 is connected to the hand-push wheel 1 202, the hand-push wheel 1 202 is turned to rotate in the first sleeve 101 or the second sleeve 102 and can transmit the second direction adjustment part 420 to drive the suspension shaft 430 to rotate horizontally. When the second direction adjustment part 420 is connected to the hand-push wheel 2 302, the hand-push wheel 2 302 is turned to rotate in the first sleeve 101 or the second sleeve 102 and can transmit the second direction adjustment part 420 to drive the suspension shaft 430 to rotate horizontally. The hand-dialing wheel 2 302 rotates in the first sleeve 101 or the second sleeve 102 and can transmit the second direction adjustment part 420 to drive the suspension shaft 430 to rotate horizontally. The hand-dialing wheel 1 202 and the hand-dialing wheel 2 302 are inserted into the hand grips at both ends of the handlebars 100 of the electric power-assisted bicycle. When the hands are held on the hand grips 1 200 and 2 during riding, the hand-dialing wheel 1 202 and the hand-dialing wheel 2 302 are rotated by the hands, that is, the first direction adjustment part 410 and the second direction adjustment part 420 are transmitted, and the transmission to the first direction adjustment part 410 can drive the suspension shaft 430 to rotate axially with its axis as the axis, and the transmission to the second direction adjustment part 420 can drive the suspension shaft 430 to rotate horizontally, and then can drive The mobile terminal loaded on the suspension shaft 430 makes axial rotation about its axis and drives the mobile terminal loaded on the suspension shaft 430 to rotate horizontally, thereby realizing adjustment of various directions and angles of the mobile terminal loaded on the bicycle. In addition, the device can adjust the angle of the mobile terminal on the bicycle at multiple angles without taking both hands off the handlebars and operating the bicycle normally while riding. This not only facilitates viewing the content of the mobile terminal, but also avoids the situation in which the rider has to operate the bicycle with one hand and adjust the angle of the mobile phone with the other hand during riding, which causes the rider to be unable to concentrate on riding and lose normal control of the bicycle, thereby causing traffic accidents and posing certain safety hazards.

[0058] In this embodiment, Figure 1-Figure 8 As shown, the first direction adjustment unit 410 includes:

[0059] The worm gear set 1 411 (the worm gear and the worm are meshed with each other, which is an existing component and will not be described in detail here) is arranged in the middle sleeve 103, one end of the worm 1 411b of the worm gear set 1 411 is coaxially fixed on the hand-push wheel 1 202 or the hand-push wheel 2 302, and the worm gear 1 411a is rotatably connected to the inside of the middle sleeve 103 through a rotating shaft;

The worm gear 422a is used to drive the vertical pipe 414 and the suspension shaft 430 on the adjustment box 416 to rotate around the axis of the vertical pipe 414. When the gear 1 421a is coaxially fixed on the hand dial wheel 2 302, when the hand dial wheel 2 302 rotates, it can drive the gear 1 421a to rotate. Due to the meshing relationship between the gear 1 421a and the gear 2 421b in the gear set 421, the gear 1 421a drives the gear 2 421b to rotate. The gear 2 421b is coaxially fixed with the worm gear 422b, so it can drive the worm gear 421a to rotate. Rod 2 422b rotates, and due to the meshing relationship between worm gear 2 422a and worm gear 2 422b, worm gear 2 422b drives worm gear 2 422a to rotate, and worm gear 2 422a is coaxially sleeved on the outside of vertical pipe 414, worm gear 2 422a drives vertical pipe 414 to rotate, and an adjustment box 416 is provided on the top of vertical pipe 414, and vertical pipe 414 drives adjustment box 416 to rotate.

[0071] In this embodiment, Figure 1-Figure 8As shown, the linkage assembly 417 includes an inner gear ring 4171, a rotating column 4172 and a snap-fitting member 4173. The inner gear ring 4171 is coaxially fixed to the top of the screw rod 415. The rotating column 4172 is fixed to the bottom of the rack of the gear rack assembly 418 and is coaxially located in the inner gear ring 4171. The snap-fitting member 4173 moves in the rotating column 4172. The snap-fitting member 4173 includes a movable groove 4173a, an electromagnetic block 4173b, a return spring 4173c and a snap-fitting tooth block 4173d. The opening of the movable groove 4173a faces the electromagnetic block 4173b. The electromagnetic block 4173b is fixed on the inner wall of the movable groove 4173a, the return spring 4173c is fixed on one side of the electromagnetic block 4173b, the engaging tooth block 4173d is fixed on one side of the return spring 4173c, and the engaging tooth block 4173d is a magnet and mutually repels the magnetic pole of the energized electromagnetic block 4173b, the limiting member 419 includes a slide groove 4191 and a slider 4192 adapted to the slide groove 4191 and sliding in the slide groove 4191, and the slide groove 4191 is opened on the gear On one side of the rack of the rack assembly 418, the slider 4192 is fixed to the inner wall of the adjustment box 416, and by energizing the electromagnetic block 4173b, the electromagnetic block 4173b generates a magnetic pole that repels each other with the engaging tooth block 4173d. Therefore, the engaging tooth block 4173d in the movable groove 4173a can be pushed out of the movable groove 4173a, and the stretching return spring 4173c is stuck in the inner teeth of the inner gear ring 4171. When the worm wheel 411a rotates, the column 412 and the nut sleeve 413 are driven to rotate. In addition, due to the slider in the adjustment box 416 The block 4192 slides in the slide groove 4191 in the rack of the gear rack assembly 418, and the rotating column 4172 below the rack is clamped in the inner gear ring 4171 through the engaging gear block 4173d, and the gear ring is coaxially fixed to the top of the screw rod 415, so that the screw rod 415 cannot rotate with the nut sleeve 413. Therefore, the spiral connection between the screw rod 415 and the nut sleeve 413 is utilized to make the screw rod 415 displace along its axis, and also drive the rack to displace along the axis of the screw rod 415, so as to realize the linkage relationship that the rack of the gear rack assembly 418 does not rotate with the riser 414.

[0072] When the circuit of the electromagnetic block 4173b is closed, the electromagnetic block 4173b loses the magnetic pole that repels each other with the engaging tooth block 4173d. At this time, due to the elastic force of the stretched return spring 4173c, the engaging tooth block 4173d stuck on the inner gear ring 4171 can be pulled back into the movable groove 4173a again. When the vertical pipe 414 rotates, the vertical pipe 414 drives the adjusting box 416 to rotate, and the rotating adjusting box 416 links the gear rack group 418 and the suspension shaft 430 in the adjusting box 416 to rotate around the axis of the vertical pipe 414. At this moment, the rotating column 4172 under the rack of the gear rack group 418 has no effect on the inner gear ring 4171 through the engaging tooth block 4173d. Therefore, the rack rotated by the linkage of the adjusting box 416 will not cause the screw rod 415 to rotate, thereby realizing the linkage gear rack group 418 to follow the rotation.

[0073] In this embodiment, Figure 1-Figure 8 As shown, a mobile phone holder 500 is sleeved on the outer circumference of the suspension shaft 430 to facilitate fixing the mobile phone.

[0074] In this embodiment, Figure 1-Figure 8 As shown, the hand grip 200 also includes a hand shift sleeve 203, the hand shift sleeve 203 has a conical cross-section and is fixed on the circumferential outer wall of one end of the hand wheel 202, and is located between the hand wheel 202 and the handle 201, wherein the end of the hand shift sleeve 203 with a larger diameter faces the handle 201, and the hand grip 2 300 also includes a hand shift sleeve 2 303, the hand shift sleeve 2 303 has a conical cross-section and is fixed on the circumferential outer wall of one end of the hand wheel 2 302, and is located between the hand wheel 2 302 and the handle 2 301, wherein the end of the hand shift sleeve 2 303 with a larger diameter faces the handle 2 301, thereby increasing the contact area between the hand and the hand wheel, thereby making it convenient for the rider to rotate the hand wheel with the hand holding the hand grip, thereby realizing convenient adjustment of the orientation and angle of the mobile terminal.

[0075] In this embodiment, Figure 1-Figure 8 As shown, a locking assembly 600 is provided between the handle 1 201 and the first sleeve 101, and between the handle 2 301 and the second sleeve 102, wherein the locking assembly 600 is used to fasten the handle 1 201 to the first sleeve 101 and to fasten the handle 2 301 to the second sleeve 102, and the locking assembly 600 includes an L-shaped insertion rod 601 and a locking ring 602, wherein the insertion rod 601 is fixed at the bottom of the handle 1 201 and the handle 2 301 and one end of the insertion rod extends into the locking ring 602, and the locking ring 602 is fixed at the bottom of the first sleeve 101 and the second sleeve 102 and corresponds to the insertion rod 601.

[0076] The specific working process of the present invention is as follows:

[0077] (1) Adjustment of the first direction (the phone's vertical screen angle when in horizontal state or the phone's tilt angle when in horizontal state)

[0078] First, the electromagnetic block 4173b is energized to generate magnetic poles that repel each other with the engaging tooth block 4173d, thereby pushing the engaging tooth block 4173d in the movable groove 4173a out of the movable groove 4173a, and at the same time stretching the return spring 4173c and engaging it in the inner teeth of the inner gear ring 4171;

[0079] When the hand wheel 202 is turned by hand, the worm 411b can be driven to rotate. Due to the meshing relationship between the worm wheel 411a and the worm 411b, the worm wheel 411a can also be driven to rotate axially. The column 412 and the nut sleeve 413 are coaxially fixed on the top of the worm wheel 411a, thus driving the column 412 and the nut sleeve 413 to rotate.

[0080] In addition, since the slider 4192 in the adjustment box 416 slides in the slide groove 4191 in the rack of the gear rack assembly 418 and the rotating column 4172 below the rack is stuck in the inner gear ring 4171 through the engaging gear block 4173d, and the gear ring is coaxially fixed to the top of the screw rod 415, the screw rod 415 cannot rotate with the nut sleeve 413. Therefore, the spiral connection between the screw rod 415 and the nut sleeve 413 is utilized to displace the screw rod 415 along its axis, and also drive the rack to displace along the axis of the screw rod 415. The displaced rack drives the gear to rotate, and the gear drives the suspension shaft 430 to rotate around the axis of the suspension shaft 430, so that the mobile terminal loaded on the suspension shaft 430 can rotate around the axis of the suspension shaft 430, thereby adjusting the tilt angle of the mobile terminal.

[0081] (2) Second direction (switching between horizontal and vertical screen viewing angles of the mobile phone in horizontal state) adjustment

[0082] When the circuit of the electromagnetic block 4173b is closed, the electromagnetic block 4173b loses the magnetic poles that repel each other with the engaging tooth block 4173d. At this time, due to the elastic force of the stretched return spring 4173c, the engaging tooth block 4173d stuck on the inner gear ring 4171 can be pulled back into the movable groove 4173a again.

[0083] When gear one 421a is coaxially fixed on hand dial wheel two 302, when hand dial wheel two 302 is rotated by hand, gear one 421a can be driven to rotate together. Due to the meshing relationship between gear one 421a and gear two 421b in gear set 421, gear one 421a drives gear two 421b to rotate. Gear two 421b is coaxially fixed with worm two 422b, and therefore, worm two 422b can be driven to rotate. Due to the meshing relationship between worm wheel two 422a and worm two 422b, worm two 422b drives worm wheel two 422a to rotate, and worm wheel two The coaxial sleeve 422a is arranged outside the vertical tube 414, the worm gear 422a drives the vertical tube 414 to rotate, and the adjusting box 416 is arranged on the top of the vertical tube 414, and the vertical tube 414 drives the adjusting box 416 to rotate. At this moment, the rotating column 4172 below the rack of the gear rack set 418 can not act on the inner gear ring 4171 through the engaging tooth block 4173d, so the rack rotated by the linkage of the adjusting box 416 will not cause the screw rod 415 to rotate (here, the friction force of the screw rod 415 in the nut sleeve 413 should be greater than the torque force of the screw rod 415 driving the nut sleeve 413 to rotate);

[0084] At this moment, the rotating adjustment box 416 links the gear rack set 418 and the suspension shaft 430 in the adjustment box 416 to rotate around the axis of the vertical tube 414, so that the mobile terminal loaded on the suspension shaft 430 can be rotated from a horizontal landscape screen to a horizontal portrait screen.

Compared with Example 1, this embodiment only changes the connection relationship between the handle 1 201 and the handle 2 301 fastened to the first sleeve 101 and the second sleeve 102. A locking assembly 600 is provided between the handle 1 201 and the second sleeve 102 as well as between the handle 2 301 and the first sleeve 101. The locking assembly 600 is used to fasten the handle 1 201 to the second sleeve 102 and to fasten the handle 2 301 to the first sleeve 101. The locking assembly 600 includes an L-shaped insertion rod 601 and a locking ring 602. The insertion rod 601 is fixed at the bottom of the handle 1 201 and the handle 2 301 and one end extends into the locking ring 602.
