Description

Hinge and intelligent glasses

Technical Field

The disclosure relates to the technical field of connecting pieces, in particular to a hinge and intelligent glasses.

Background

Because the head sizes of users wearing the intelligent glasses are different, the glasses legs are required to maintain a certain clamping force when the intelligent glasses are designed, and the glasses legs are folded inwards and outwards by a certain angle relative to the glasses frame, and meanwhile, damping sense is guaranteed. However, the space of the current intelligent glasses is relatively narrow, if a traditional marble core type rotating shaft is adopted, only a single spring can be used for providing the clamping force of the glasses legs, and the clamping force is often insufficient when the glasses are worn. At this time, the sufficient clamping force is ensured while the inner and outer folding of the glasses legs and the damping sense are ensured.

The first connecting seat 3 may be connected to the temple 200 of the smart glasses, and the second connecting seat 7 may be connected to the frame 300 of the smart glasses. The first elastic component 4 and the second elastic component 8 are located at two sides of the rotation axis of the first connecting seat 3 (or the rotation axis of the glasses leg 200), and the extending direction of the first elastic component 4 is different from that of the rotation axis of the first connecting seat 3, and the first elastic component 4 can extend along the length direction of the glasses leg 200. The extending direction of the second elastic component 8 is different from the extending direction of the rotating axis of the first connecting seat 3, and the second elastic component 8 can extend along the length direction of the glasses leg 200, so that the space of the glasses leg and the glasses frame on the intelligent glasses is fully utilized, the size of the two elastic components is increased, the elastic damping is increased, and the clamping force of the glasses leg 200 of the intelligent glasses is improved.

Some embodiments of the present disclosure provide mating structures of the first connection holder 3 and the second connection holder 7. As shown in fig. 1, 2 and 3, the hinge 100 includes a first shaft body 1 and a second shaft body 5. The second shaft body 5 and the first shaft body 1 are arranged side by side. The first shaft body 1 and the second shaft body 5 are connected through a connecting piece a, a first cam 2 is arranged on the first shaft body 1, and a second cam 6 is arranged on the second shaft body 5. The first connecting seat 3 is rotatably connected to the first shaft body 1, the extending direction of the first elastic component 4 is different from the extending direction of the first shaft body 1, and the first elastic component 4 abuts against the first cam 2. The second connecting seat 7 is rotatably connected to the second shaft body 5, the extending direction of the second elastic component 8 is different from the extending direction of the second shaft body 5, and the second elastic component 8 abuts against the second cam 6.

Of course, the third component is used to make the two components indirectly contact, and the third component is used to make the first component and the second component reach the effect of propping, which is also a technical scheme to be protected in the disclosure.

The first spring 42 is sleeved on the first rod 41 and has a first end propped against the first connecting seat 3 and a second end propped against the third cam 43, so that the third cam 43 is propped against the first cam 2. During rotation of the first coupling seat 3 about the first axis 1 relative to the second coupling seat 7, the third cam 43 moves along the surface of the first cam 2 changing position. The third cam 43 presses or releases the first spring 42 due to the fluctuation of the circumferential side surface of the first cam 2. The first rod 41 may be substantially perpendicular to the first shaft 1.

Some embodiments of the present disclosure provide for the construction of a second elastic assembly 8, such as shown in fig. 1 and 4.

The second rod 81 is different from the second shaft 5 in extending direction, the second rod 81 is movably connected to the second connecting seat 7, and the second rod 81 has a fourth cam 83 disposed at an end. The second spring 82 is sleeved on the second rod 81, and has a first end propped against the second connecting seat 7 and a second end propped against the fourth cam 83, so that the fourth cam 83 is propped against the second cam 6. In the process that the first connecting seat 3 rotates around the first shaft body 1 relative to the second connecting seat 7 so that the first cam 2 extrudes or releases the first elastic component 4, the first connecting seat 3 drives the second shaft body 5 to drive the second cam 6 to rotate, and the peripheral side surface of the second cam 6 is fluctuated so as to extrude or release the second elastic component 8. The first elastic component and the second elastic component enable the elastic damping of the hinge to be larger, and the clamping force of the glasses leg is remarkably improved.

Some embodiments of the present disclosure provide a schematic view of the mating structure of the first connecting seat 3, the first cam 2 and the first elastic assembly 4. As shown in fig. 1, 2 and 8, the first connection base 3 includes a first connection block 32 and two first support arms 31. The first connecting block 32 is connected with the first elastic member 4. The two first support arms 31 have first ends connected by the first connection block 32 and second ends connected to the first shaft body 1, and an accommodating space is defined between the two first support arms 31 to accommodate the first cam 2 and the first elastic member 4. The two first supporting arms 31 can be arranged in parallel, and the space is saved and the structural arrangement is more reasonable by arranging the first cam 2 and the first elastic component 4 in the accommodating space defined between the two first supporting arms 31.

Some embodiments of the present disclosure provide a schematic structural view of the driving engagement of the first connection socket 3 and the second connection socket 7. As shown in fig. 1 and 5, the hinge 100 further includes a fifth cam 9 and a sixth cam 10. The fifth cam 9 is connected to the first connecting seat 3 so as to be rotatable in synchronization with the first connecting seat 3 around the first shaft body 1. The sixth cam 10 is fixedly connected with the second shaft body 5 so as to be rotatable in synchronization with the second shaft body 5. During the rotation of the first connecting seat 3 around the first shaft body 1 relative to the second connecting seat 7, the fifth cam 9 drives the sixth cam 10 to rotate so as to rotate the second shaft body 5. The second shaft body 5 rotates to drive the second cam 6 to synchronously rotate to compress or release the second elastic component 8. The cross section of a part of the shaft section of the second shaft body 5 can be non-circular, the second cam 6 and the sixth cam 10 can both have non-circular holes, and the second cam 6 and the sixth cam 10 can both be sleeved on the non-circular shaft section of the second shaft body 5 through the non-circular holes, so that the second shaft body 5, the second cam 6 and the sixth cam 10 can synchronously rotate.

The first cam 2 and the fifth cam 9 are arranged in order along the length direction of the first shaft body 1, and the second cam 6 and the sixth cam 10 are arranged in order along the length direction of the second shaft body 5. The fifth cam 9 and the sixth cam 10 are in contact with each other with a gap between the first cam 2 and the second cam 6. When the first connecting seat 3 rotates around the first shaft body 1 relative to the second connecting seat 7, the first cam 2 can squeeze or release the third cam 43 to compress the first spring 42, meanwhile, the first connecting seat drives the fifth cam 9 to rotate, the fifth cam 9 drives the sixth cam 10 to rotate to drive the second shaft body 5 to rotate, the second shaft body 5 rotates to drive the second cam 6 to synchronously rotate, so as to squeeze or release the fourth cam 83, and the second spring 82 is compressed or released through the fourth cam 83, so that the effect of simultaneously adjusting the compression of the elasticity of the two spring components is achieved, the resistance is obviously provided, and the clamping force of the glasses leg 200 of the intelligent glasses is improved.

Some embodiments of the present disclosure provide for a mating structure of the first cam 2 and the first connecting seat 3. As shown in fig. 5 and 6, the fifth cam 9 is rotatably sleeved on the first shaft body 1, and the fifth cam 9 is connected to the first connecting seat 3 through a positioning pin e. For example, the first support arm 31 of the first connection base 3 may be provided with a connection groove 311, and the fifth cam 9 may be provided with a first fixing hole 91 and a second fixing hole 92. The fifth cam 9 is sleeved on the first shaft body 1 through the first fixing hole 91. The positioning pin e may have one end coupled to the second fixing hole 92 through the coupling groove 311. The positioning pin e may be provided with external threads, the connection groove 311 may be provided with internal threads, and the positioning pin e may be screwed to the connection groove 311.

The sixth cam 10 is sleeved on the second shaft body 5, and the sixth cam 10 and the second shaft body 5 synchronously rotate.

Some embodiments of the present disclosure provide a mating structure of the connection piece a with the first shaft body 1 and the second shaft body 5, as shown in fig. 2, 7 and 10, the connection piece a is fixed to the first shaft body 1 and the second shaft body 5 through an elastic piece b, and the elastic piece b is located at a side of the connection piece a facing away from the first connection seat 3 and the second connection seat 7. Two connecting holes a1 are arranged on the connecting piece a. The connecting piece a is sleeved on the first shaft body 1 and the second shaft body 5 respectively through two connecting holes a1. In order to prevent the connection piece a from separating from the first shaft body 1 and the second shaft body 5 and increase damping when the two shaft bodies rotate, in the embodiment of the disclosure, the elastic pieces b are installed on the first shaft body 1 and the second shaft body 5, the connection piece a is located between the elastic pieces b and the first connection seat 3 and the second connection seat 7, and under the limiting effect of the elastic pieces b, the connection piece a cannot separate from the first shaft body 1 and the second shaft body 5.

The elastic member b is closely contacted with the connecting member a, and the connecting member a is closely contacted with the first connecting seat 3 and the second connecting seat 7, so that the elastic member b and the connecting member a have larger friction force. When the first connecting seat 3 rotates relative to the second connecting seat 7, the connecting piece a moves relative to the first connecting seat 3 and the second connecting seat 7, so that larger friction resistance exists between the connecting piece a and the first connecting seat 3 and the second connecting seat 7, and the damping of the hinge 100 is increased. The elastic member b may have a C-shaped sheet shape. The ends of the first shaft body 1 and the second shaft body 5 are provided with annular clamping grooves, the elastic piece b can be sleeved on the corresponding shaft body, the elastic piece b is clamped in the annular clamping grooves, and the position of the elastic piece b is locked and cannot move along the length direction of the shaft body. Under the limit of the elastic piece b, the connecting piece a is tightly contacted with the first connecting seat 3 and the second connecting seat 7, so that the friction force is increased.

Some embodiments of the present disclosure provide the principle of the mating structure of the cams of hinge 100. As shown in fig. 1, 4 and 5, the first cam 2 has an inner apex 21. The first connection base 3 may be connected to the temple 200 of the smart glasses, and the second connection base 7 may be connected to the frame 300 of the smart glasses. In the process of folding the temple 200 toward the frame 300, the elastic compression amounts of the first elastic component 4 and the second elastic component 8 are the largest when the first connecting seat 3 rotates around the first shaft body 1 toward the second connecting seat 7 until the first elastic component 4 is located at the inner vertex 21. After the first connecting seat 3 rotates around the first shaft body 1 towards the second connecting seat 7 until the first elastic component 4 passes through the inner vertex 21, the first elastic component 4 descends from the inner vertex 21, and the first elastic component 4 is released, so that the first elastic component 4 and the second elastic component 8 can elastically reset, and the first connecting seat 3 is driven to continue to rotate towards the second connecting seat 7.

Fig. 4 shows a cross-sectional view of the hinge with the temples of the smart glasses in a naturally open state. Fig. 9 is a schematic view showing a state that a temple of the smart glasses is folded inward by a certain angle. Fig. 10 shows a state diagram of the hinge of fig. 9. In the process of folding the glasses leg 200 from the natural open state to the inward folding state, the first connecting seat 3 drives the third cam 43 to rotate clockwise on the surface of the first cam 2, the first connecting seat 3 drives the fifth cam 9 to press the sixth cam 10 downwards, so that the second shaft body 5 rotates anticlockwise, the second cam 6 is driven to rotate anticlockwise, and the fourth cam 83 slides relative to the surface of the second cam 6. Referring to fig. 5, when the third cam 43 climbs clockwise along the surface of the first cam 2 to reach the inner apex 21, the fourth cam 83 also slides along the surface of the second cam 6 to the apex, at which time the spring is compressed to the greatest extent, and the damping feeling is at the greatest. As shown in fig. 11 and 12, when the third cam 43 passes through the inner vertex 21 and the fourth cam 83 passes through the top of the second cam 6, it descends on the surfaces of the first cam 2 and the second cam 6, respectively, and the temple 200 is automatically folded toward the frame 300 under the action of the spring force.

Some embodiments of the present disclosure provide for the structure of the first cam 2 of the hinge 100. The first cam 2 shown in fig. 4 has an outer apex 22. When the temple is stretched out, the first elastic component 4 and the second elastic component 8 are compressed in a state that the first connecting seat 3 rotates around the first shaft body 1 away from the second connecting seat 7 until the first elastic component 4 is located at the outer vertex 22, and an elastic reset trend exists, so that the first connecting seat 3 is driven to rotate towards the second connecting seat 7.

It will be appreciated that the shape of the first cam 2 is symmetrical in one cross-section, see fig. 4 etc. The first cam 2 has an inner fixed point 21 on the axis of symmetry and two outer fixed points 22 on either side of the axis of symmetry. From the inner fixed point 21 to the outer fixed point 22, the first cam 2 has a recess. The second cam 6 has the same shape as the first cam 1.

When the temple 200 continues to be stretched out from the natural open state, the first connecting seat 3 may be driven to rotate outwards, at this time, the third cam 43 slides downwards on the surface of the first cam 2, after passing through the concave portion of the first cam 2, the third cam 43 climbs on the surface of the first cam 2 towards the outer vertex 22, so that the first spring 42 of the first elastic component 4 is compressed, and a spring damping force is generated. The outer vertex 22 is reached after the third cam 43 slides a certain distance along the surface of the first cam 2. At this time, the first connecting seat 3 stops rotating, the first connecting seat 3 is released, and the first connecting seat 3 returns to the natural open position under the elastic force of the first elastic component 4.

It should be noted that the springs of the first elastic member 4 and the second elastic member 8 are in a compressed state in each state during the unfolding and folding of the temple 200. The difference is only the degree of compression. Referring to fig. 11, in a state where the temple 200 is folded to be completely closed with respect to the frame 300, the fourth cam 83 abuts against the lowermost position of the second cam 6, and the compression degree of the second spring 82 is minimized. When the temple 200 is extended outward to the position shown in fig. 13, 14 and 15, the third cam 43 abuts against the lowest point of the first cam 2, and the compression degree of the first spring 42 is minimized. As the temple 200 continues to expand outwardly from the state shown in fig. 13, the third cam 43 starts to climb reversely on the first cam 2, and the temple 200 drives the fifth cam 9 to rotate counterclockwise, so that the sixth cam 10 climbs reversely on the fifth cam 9, and the second cam 6 then rotates clockwise, pressing the fourth cam 83 rightward, causing the second spring 82 to also compress. Under the action of the two springs, the temples 200 have a tendency to move back, and the clamping force of the temples 200 is improved.

Some embodiments of the present disclosure provide a structure of smart glasses, as shown in fig. 2 and 3, the smart glasses include: a frame 300, a temple 200, and a hinge 100. The first connecting seat 3 is connected to the glasses leg 200, the second connecting seat 7 is connected to the glasses frame 300, the first shaft body 1 is fixed to the glasses frame 300, and the second shaft body 5 is rotatably connected to the glasses frame 300. In the process of rotating the temple 200 to rotate the first connecting seat 3 around the first shaft body 1 relative to the second connecting seat 7, so that the first cam 2 extrudes or releases the first elastic component 4, the first connecting seat 3 drives the second shaft body 5 to drive the second cam 6 to rotate so as to extrude or release the second elastic component 8. The embodiments of the present disclosure provide that the first and second elastic assemblies make the elastic damping greater, significantly improving the temple clamping force.

The temple 200 and the first connecting base 3 can be connected by a screw c, and the frame 300 and the second connecting base 7 can be connected by the screw c. When the glasses leg 200 is rotated, the first connecting base 3 is driven to rotate, and the first shaft body 1 is fixed on the glasses frame 300 and does not rotate along with the first connecting base 3. The third cam 43 can slide along the first sliding groove 321 of the first connecting seat 3 during the rotation of the temple 200, and presses the first spring 42 to generate a damping force. The fifth cam 9 and the first connecting seat 3 are fixed together by a positioning pin e, and when the first connecting seat 3 rotates, the fifth cam 9 rotates at the same angle. The fifth cam 9 presses down the sixth cam 10 to rotate in the rotating process, and the sixth cam 10 drives the second shaft body 5 and the second cam 6 to rotate at the same angle in the rotating process. The second cam 6 and the fourth cam 83 contact to slide and compress the second spring 82, thereby generating a spring damping force.

It should be noted that fig. 4, 5, 8 and 15 in the drawings of the specification of the present disclosure are all sectional views, and the slightly darker portions are cut-away portions.

The foregoing description has been presented for purposes of illustration and description. Furthermore, this description is not intended to limit the embodiments of the disclosure to the form disclosed herein. Although a number of example aspects and embodiments have been discussed above, a person of ordinary skill in the art will recognize certain variations, modifications, alterations, additions, and subcombinations thereof.
