Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model, and the following embodiments are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted", "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Fig. 1 and 2 illustrate some embodiments of glasses provided in connection with the present disclosure, the glasses comprising: a spectacle frame 1 and a nose pad 2. One of the frame 1 and the nose pad 2 is provided with a receiving portion 131, and the other is provided with a connecting body 21. The connector 21 can be at least partially inserted into the accommodating portion 131, and the depth of the connector 21 inserted into the accommodating portion 131 of the frame 1 can be adjusted. Alternatively, the receptacle 131 can be a slot defined by one of the frame 1 and the nosepiece 2. When different consumers wear the glasses, the nose pad 2 does not need to be replaced, and the insertion depth of the connecting body 21 is adjusted so that the heights of the frame of the glasses and eyes of the consumers are consistent. The glasses provided by the present disclosure are convenient to use, do not need to be equipped with a plurality of nose pads 2, reduce the cost and save the materials.

The gear of the nose pad 2 can be defined according to the difference of the interval between the frame 1 and the nose pad 2. For example, the first gear may be understood as a first pitch between the nose pad 2 and the frame 1, and the second gear may be understood as a second pitch between the nose pad 2 and the frame 1, the first pitch and the second pitch being different.

Alternatively, by bringing the frame 1 and the nosepiece 2 closer to each other, the nosepiece 2 is disengaged from the first gear, and then the frame 1 and the nosepiece 2 are moved away from each other, the nosepiece 2 is shifted to the second gear. The nose pad 2 is moved closer to the frame 1 and the nose pad 2, the nose pad 2 is separated from the second gear, and then the frame 1 and the nose pad 2 are moved away from each other, and the nose pad 2 is shifted to the first gear. Thus, the nose pad 2 can be sequentially and cyclically switched between the respective gear positions.

Some embodiments of the present disclosure provide mating structures of the connector 21 and the receptacle 131. As shown in fig. 3 and 6, the connecting body 21 is provided with a rail groove 211 and at least two shift portions 2111 communicating through the rail groove. The glasses include a guide bar 132 and an elastic member 133. The guide bar 132 has a connection end 1322 provided at the receiving portion 131 and a free end 1321 movable along the rail groove 211. The elastic member 133 is provided between the frame 1 and the nose pad 2. The glasses are configured to: under the action of external force, the nose pad 2 and the frame 1 can approach each other, so that the free end 1321 of the guide rod 132 can move along the track groove 211 to be separated from the current gear portion 2111, and the deformation amount of the elastic member 133 is increased. Under the action of the elastic member 133, the frame 1 and the nose pad 2 are moved apart, so that the free end 1321 moves along the rail groove 211 to the other gear portion 2111.

Alternatively, as shown in fig. 6, 7 and 8, the receiving portion 131 may be a groove, and the elastic member 133 may be located at the receiving portion 131. For example, one end of the elastic member 133 abuts against the inner wall of the accommodating portion 131, and the other end of the elastic member 133 abuts against the connecting body 21. The connecting body 21 may be provided with a positioning column 212, the elastic member 133 may be a spring, and one end of the spring may be sleeved on the positioning column 212. The elastic piece 133 is always in a compressed state, so that when the nose pad 2 is pushed, elastic handfeel can be generated, and stable matching between the connecting body 21 and the spectacle frame 1 is ensured.

When the free end 1321 of the guide rod 132 moves to different gear positions, the elastic member 133 abuts against the connecting body 21, so that the free end 1321 of the guide rod 132 can be stably limited to the corresponding gear position 2111, and is not easy to shift out. When the consumer wears the glasses for the first time, if the glasses frame position is inconsistent with the height of the consumer glasses, the nose support 2 can be pushed to one side of the glasses frame 1, the gear is adjusted, the distance between the glasses frame and the nose support 2 is changed, and the height of the glasses frame is consistent with the height of eyes of the consumer. The glasses can be provided with a plurality of gear parts, and the consumer can push the nose support gradually, adjust the high position of picture frame, and the picture frame height is unanimous with consumer's eyes height.

Some embodiments of the present disclosure provide for the construction of an optional gear portion 2111, such as shown in fig. 5 and 6. The connector is provided with a track groove and at least two gear parts communicated through the track groove, the at least two gear parts comprise a gear part 2111 defined by a bending groove section on the track groove 211 and a gear part defined by a non-bending groove section. The apex angle of the bending groove section extends toward a gear portion (e.g., final gear portion 2111 a) defined by the non-bending groove section. The free end 1321 of the guide rod 132 can be clamped to the bending groove section.

The bending groove section forms a vertex angle at the bending turning position, and when the free end 1321 of the guide rod 132 moves to the bending groove section, the free end 1321 of the guide rod 132 can finally move to the vertex angle of the bending groove section and be in a stable state under the action that the elastic piece 133 pushes the connecting body 21. The vertex angle of each bending groove section extends towards the gear position portion 2111 limited by the non-bending groove section, and the connecting end 1322 of the guide rod 132 is arranged on one side of the gear position portion limited by the non-bending groove section, which is away from the bending groove section. The free end 1321 of the guide rod 132 can be moved to each gear portion 2111 in successive cycles by pushing the nose pad 2a plurality of times.

Alternatively, referring to fig. 5, the coupling body 21 may be provided with a rail groove 211. The bending groove section has a first wall 21111 near a gear portion defined by the non-bending groove section (e.g., a final gear portion 2111 a) and a second wall 21112 distant from the gear portion defined by the non-bending groove section, respectively, on both sides in the width direction. The first wall 21111 and the second wall 21112 each protrude to one side of the gear portion defined by the non-bending groove section, and the angle formed by bending the first wall 21111 and the angle formed by bending the second wall 21112 are offset. After the free end 1321 of the guide rod 132 moves from one side of the bending groove section to the corner formed by the first wall 21111, the nose pad 2 is pushed to one side of the mirror frame again, and under the guiding action of the second wall 21112, the free end 1321 of the guide rod 132 can smoothly slide out from the other side of the bending groove section.

Optionally, the first wall 21111 defines an arcuate angle and the second wall 21112 defines an included angle. The arc angle and the included angle are staggered. The arc angle is understood to mean a smooth transition of the surface of the first wall 21111 at the apex angle, and the included angle is a sharp angle formed by a bending abrupt change of the second wall 21112 at the apex angle. After the free end 1321 of the guide bar 132 slides into the bending groove section, the free end 1321 of the guide bar 132 will eventually be stable at the arc angle. Because the arcuate corner surfaces are smooth, there is less friction damage between the free end 1321 of the guide rod 132 and the arcuate corner surfaces. When the nose pad 2 is pushed to the frame side again, the free end 1321 of the guide rod 132 can slide out of the bending groove section smoothly under the guiding action of the wall surface of the second wall 21112 at the included angle side.

Some embodiments of the present disclosure provide for the configuration of the gear portion 2111 defined by non-bending channel segments on the track channel 211. For example, as shown in fig. 5 and 6, the end of the non-bending groove section on the rail groove 211 remote from the bending groove section forms a final stage portion 2111a. The distance between the nose pad 2 and the lens frame is maximized in a state where the free end 1321 of the guide 132 is moved to the final stage position portion 2111a. The non-bending groove section does not form the gear portion 2111 by an angle, but naturally forms a gear portion at an end position of the non-bending groove section. The rail groove 211 extends in the sliding direction of the link body 21, and an end of the rail groove 211 on the side close to the connecting end 1322 of the guide rod 132 is a final stage position portion 2111a.

Some embodiments of the present disclosure provide for mating structures of the frame 1 and nose pad 2, such as shown in fig. 9 and 10, with one final stage portion 2111a included in each gear portion 2111. One of the frame 1 and the nose pad 2 is provided with a sliding groove 135, and the other is provided with a limiting block 22. The sliding groove 135 is extended along the moving direction of the connecting body 21, and the sliding groove 135 has a closed end. The stopper 22 is movably connected to the chute 135. In a state where the free end 1321 is slid to the final stage position portion 2111a, the stopper 22 is slid to the closed end of the slide groove 135. When the free end 1321 slides to the final stage portion 2111a, the distance between the nose pad 2 and the lens frame is the largest, the stopper 22 slides to the end of the sliding groove 135 to abut against the sliding groove 135, and the lens frame 1 and the nose pad 2 cannot be separated.

Some embodiments of the present disclosure provide a more detailed structural illustration of the track groove 211, such as shown in fig. 5, the track groove 211 including a slide-out groove section 211a, a return groove section 211b, and an intermediate groove section 211c. The slide-out groove section 211a is provided to extend in the moving direction of the connecting body 21. The intermediate groove section 211c communicates with the slide-out groove section 211a and the return groove section 211b, and the intermediate groove section 211c is provided with a plurality of gear portions 2111. The end of the return groove section 211b extends to the slide-out groove section 211a. The slide-out groove section 211a and the return groove section 211b are non-bending groove sections, and the intermediate groove section 211c has at least one bending groove section. One end of the slide-out groove section 211a facing away from the return groove section 211b is a final stage gear portion 2111a.

The gear position of the adjusting nose pad 2 will be described by taking the example in which the intermediate groove section 211c has two gear position portions 2111. When the free end 1321 of the guide rod 132 is located at the final stage position portion 2111a, the nose pad 2 is pushed to the side of the frame 1 once, the free end 1321 of the guide rod 132 can move to the middle groove section 211c along the sliding-out groove section 211a, and under the action that the elastic member 133 pushes the connecting body 21, the free end 1321 is limited on the first stage position portion on the middle groove section 211c. When the nose pad 2 is pushed toward the frame 1 side again, the free end 1321 of the guide bar 132 can move to the other gear portion 2111 of the intermediate groove section 211c along the direction away from the current gear portion 2111. Finally, the nose pad 2 is pushed to the side of the frame 1 again, and the free end 1321 of the guide rod 132 can be moved smoothly to the final stage portion 2111a along the return groove section 211b after being separated from the stage portion 2111.

Alternatively, as shown in fig. 5, a limit step 211d is formed between the end of the return groove section 211b and the slide-out groove section 211a. The end of the return groove section 211b extends to a position of the slide-out groove section 211a near the final stage portion 2111a. The bottom wall of the end of the return groove section 211b is higher than the bottom wall of the slide-out groove section 211a, and a limit step 211d is formed between the bottom wall of the return groove section 211b and the bottom wall of the slide-out groove section 211a. The limiting step 211d functions to define the sliding track of the free end 1321 of the guide bar 132. When the free end 1321 of the guide rod 132 slides from the final stage position portion 2111a along the slide-out groove section 211a to the end position of the return groove section 211b, the free end 1321 of the guide rod 132 does not move to the return groove section 211b due to the blocking of the limiting step 211d, but only continues to move along the slide-out groove section 211a until moving to the intermediate groove section 211c.

In the embodiment of the present disclosure, referring to fig. 5, the middle groove section 211c may be provided with only one gear portion 2111, and referring to fig. 17, the middle groove section 211c may be provided with two or more gear portions 2111. The movement principle of providing one gear portion 2111 or more gear portions 2111 for the intermediate groove section 211c is the same as the above example, and the disclosure will not be repeated.

In the embodiment of the disclosure, referring to fig. 13, the connector 21 is in a sheet shape, so as to facilitate the arrangement of the track grooves 211 on the surface. The connection body 21 may be provided with the rail groove 211 only along one side surface in the thickness direction. Some embodiments of the present disclosure provide a structure in which both sides of the connection body 21 are provided with rail grooves, for example, as shown in fig. 14, 15 and 16, both sides of the connection body 21 in the thickness direction are provided with a first rail groove a211 and a second rail groove b211, respectively. The guide rod 132 has two rod portions 132a, the two rod portions 132a are disposed on two sides of the connecting body 21, and free ends 1321 of the two rod portions 132a can move along the first track groove a211 and the second track groove b211, respectively.

The rail grooves are formed in two sides of the connecting body 21, and the two rail grooves are matched with the two rod body parts 132a respectively, so that the stability of the matched structure of the connecting body 21 and the guide rod 132 is improved. In the process that the connecting body 21 slides along the accommodating part 131, both sides of the connecting body 21 are subjected to the force exerted by the guide rods 132, both sides of the connecting body 21 are uniformly stressed, skew is not easy to generate, and abrasion is reduced.

The extended trajectories of the first and second track grooves a211 and b211 may have a path difference: for example, fig. 16 shows that the first rail groove a211 and the second rail groove b211 have different extending tracks, and the two rails together define a moving path of the free end 1321 of the guide bar 132, so that the free end 1321 of the guide bar 132 can only move along a set path.

Fig. 16 shows a schematic structural view of a first rail groove a211 and a second rail groove b211 provided on both side surfaces of the connection body 21 in the thickness direction, respectively. The first rail groove a211 and the second rail groove b211 have different extending tracks. In the drawing, the arrow shows the movement locus of the free ends 1321 of the two rod portions 132 a. Hereinafter, the two rod portions 132a are distinguished by the left and right rod portions 132a and 132a, respectively, the two sides of the connector in the thickness direction are the left and right sides 21a and 21b, respectively, the left side 21a is provided with the first rail groove a211, the right side 21b is provided with the second rail groove b211, the free end of the left rod portion 132a is movable along the first rail groove a211, and the free end of the right rod portion 132a is movable along the second rail groove b211.

To move the free end 1321 of the left lever portion 132a along the upward arrow in the left drawing of fig. 16, it is necessary that the side wall of the right-drawing second rail groove b211 restricts the movement of the free end 1321 of the right lever portion 132a in the direction indicated by the upward arrow in the right drawing. When the free ends 1321 of the two lever portions 132a are moved to the top position, the free ends 1321 of the two lever portions 132a are moved to the shift position portion 2111 under the restriction of the upper slope a on the first rail groove a211 and the left slope b of the second rail groove b211. When the nose pad 2 is pushed to the side of the frame 1 once again, the free ends 1321 of the two rod portions 132a continue to move upwards under the restriction of the left inclined plane b and the right inclined plane c, and finally move downwards under the restriction of the side walls of the track groove 211, and return to the bottom final gear portion 2111a.

Some embodiments of the present disclosure provide a mating structure of the guide bar 132 and the receiving portion 131, for example, as shown in fig. 7 and 13, the receiving portion 131 has a fixing hole 134 therein, and the connection end 1322 of the guide bar 132 is rotatably connected to the fixing hole 134. The guide rod 132 includes a main rod body, where the connection end 1322 and the free end 1321 of the guide rod 132 are disposed at two ends of the main rod body, and the connection end 1322 and the free end 1321 may be disposed at an angle with respect to the main rod body, for example, substantially perpendicular to the main rod body. The connection end 1322 is rotatably connected to the fixing hole 134 in the receiving portion 131, and the free end 1321 can move along the track groove 211, and the guide bar 132 swings around the connection end 1322 during the movement of the free end 1321 along the track groove 211.

In order to prevent the connection end 1322 of the guide rod 132 from being separated from the fixing hole 134, which may lead to failure of the guide rod 132, as shown in fig. 2, 12 and 13, in the embodiment of the disclosure, a limiting member 3 may be disposed, where the limiting member 3 is located on a side of the guide rod 132 away from the fixing hole 134, and the limiting member 3 plays a role in limiting the guide rod 132, so as to prevent the guide rod 132 from moving to a side of the limiting member 3, which may lead to the connection end 1322 of the guide rod 132 being separated from the fixing hole 134. The limiting piece 3 may include a spring piece 31, when the limiting piece 3 is disposed on the inner wall of the accommodating portion 131, the spring piece 31 can abut against the guide rod 132, so that the guide rod 132 only swings during moving along the track groove 211, and the connection end 1322 of the guide rod 132 is not separated from the fixing hole 134 in the accommodating portion 131. The limiting piece 3 can comprise a straight plate body, the middle part of the straight plate body is provided with a hollowed part, the elastic piece 31 is located at the hollowed part, the elastic piece 31 is connected to the straight plate body, and the elastic piece can be of an elastic arm structure. When the straight body is attached to the inner wall of the accommodating portion 131, the elastic sheet protrudes toward the guide rod 132 to elastically abut against the guide rod 132.

The nose pad 2 is sandwiched between the nose and the glasses holder when the glasses are worn. If the weight of the glasses is large, the elastic member 133 may be compressed to a small extent, so that the nose pad 2 cannot be completely located at the position corresponding to the gear portion 2111. The elastic member 133 may be a spring, and in order to solve this problem, the elastic force may be increased by selecting a spring type to overcome the problem. An elastic piece can be arranged on the inner wall of the accommodating part 131, and can be propped against the connecting body 21 on the nose support 2, so that the friction force between the nose support 2 and the spectacle frame 1 is increased, and the resistance of the relative movement between the nose support 2 and the spectacle frame 1 is increased.

Some embodiments of the present disclosure provide a schematic view of the structure of eyeglasses, referring to fig. 1 and 2, the eyeglass frame 1 includes a first eyeglass frame 11, a second eyeglass frame 12, and a nose bridge 13, the nose bridge 13 connecting the first eyeglass frame 11 and the second eyeglass frame 12. The nose bridge 13 is provided with a receiving portion 131. The nose pad 2 is provided with a connector 21. The nose bridge 13 is more space than the nose pad 2, and the accommodating portion 131 is more convenient to be arranged.

Some embodiments of the present disclosure provide a specific assembly structure of a nose pad and a frame of glasses, as shown in fig. 1 and 2, a nose bridge 13 is provided with a receiving portion 131, and the receiving portion 131 may be an integrally exposed groove, and the smart glasses further include a cover plate 4. In the process of assembling the glasses, the connector 21 on the nose pad 2 is firstly placed in the groove, and the position of the guide rod 132 is adjusted so that the free end 1321 of the guide rod 132 is positioned in the track groove. Then, the cover plate 4 is put on the nose bridge 13, and the cover plate 4 is fixed on the nose bridge 13 by the fastener 5, and the cover plate 4 covers the groove. When the limiting piece 3 is arranged on the glasses at the same time, the limiting piece 3 can be covered on the groove, and then the cover plate 4 is covered on the outer side of the limiting piece 3. The fastener passes through the cover plate 4 and the limiting piece 3 in sequence and is connected to the nose bridge 13.

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.
