Description

Technical Field

[0001] This application belongs to the field of eyewear technology, specifically, it relates to a nose pad module and VR glasses. Background Technology

[0002] Eyeglasses, as the most commonly used vision correction and accessory tool, are becoming increasingly widely used. Eyeglasses generally consist of a frame, lenses, and temples. For comfortable wear, nose pads are usually added where the frame contacts the bridge of the nose. These nose pads are often made of soft materials, reducing pressure on the bridge of the nose during prolonged wear.

[0003] In existing eyeglasses, the nose pads are fixedly connected to the frame, and the distance between the two nose pads remains constant. However, due to individual differences in nose bridge height, the same glasses may feel too tight on some users and too loose on others, reducing the suitability and comfort of the glasses.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0055] Reference Figures 1 to 3 This application provides a nose pad module, the nose pad module comprising:

[0056] The nose pad unit 1 includes a left rack portion 11, a left nose pad 12, a right rack portion 13 and a right nose pad 14, wherein the left nose pad 12 is connected to the left rack portion 11 and the right nose pad 14 is connected to the right rack portion 13.

[0057] Adjustment unit 2 includes gear 21, the opposite sides of which mesh with the left rack portion 11 and the right rack portion 13 respectively, so that when the gear 21 rotates, the left nose pad 12 and the right nose pad 14 can move closer to each other or further away from each other.

[0058] Specifically, see Figure 3 The left rack portion 11 may include a first rack segment and a first connecting segment connected to each other, and the right rack portion 13 may include a second rack segment and a second connecting segment connected to each other. The first rack segment and the second rack segment respectively mesh with opposite sides of the gear 21. The first connecting segment and the second connecting segment are respectively connected to the left nose pad 12 and the right nose pad 14. The left rack portion 11 and the right rack portion 13 can be movably connected to the frame by rack screws, so that the rotation of the gear 21 can move the left rack portion 11 and the right rack portion 13 closer to each other or further away from each other, thereby moving the left nose pad 12 and the right nose pad 14 closer to each other or further away from each other.

[0059] When designed for different users, the nose pad module provided in this embodiment can simultaneously move the left nose pad 12 and the right nose pad 14 by rotating the gear 21. This allows the distance between the left and right nose pads 12 and 14 to be adjusted as they move closer or further apart, achieving a comfortable fit for the user. In other words, the user can adjust the distance between the left and right nose pads 12 and 14 according to their own needs, such as adjusting the distance based on the size or height of their nose bridge, thus achieving a comfortable fit.

[0060] The nose pad module provided in this application embodiment includes a nose pad unit 1 and an adjustment unit 2. The nose pad unit 1 includes a left rack portion 11, a left nose pad 12, a right rack portion 13, and a right nose pad 14. The left nose pad 12 is connected to the left rack portion 11, and the right nose pad 14 is connected to the right rack portion 13. The adjustment unit 2 includes a gear 21. The opposite sides of the gear 21 mesh with the left rack portion 11 and the right rack portion 13, respectively, so that when the gear 21 rotates, the left nose pad 12 and the right nose pad 14 can move closer to each other or further away from each other, thereby improving the applicability and wearing comfort of the nose pad module.

[0061] Optionally, see Figures 4 to 7 The adjustment unit 2 further includes a knob 22, which is connected to the gear 21. The knob 22 is movable in the axial direction of the gear 21 so that the gear 21 can switch between a first position and a second position.

[0062] With the gear 21 in the first position, rotating the knob 22 counterclockwise causes the gear 21 to rotate counterclockwise and move simultaneously through the left rack portion 11 and the right rack portion 13, which in turn causes the left nose pad 12 and the right nose pad 14 to move closer to each other.

[0063] With the gear 21 in the second position, rotating the knob 22 clockwise causes the gear 21 to rotate clockwise and move simultaneously through the left rack portion 11 and the right rack portion 13, causing the left nose pad 12 and the right nose pad 14 to move away from each other.

[0064] Specifically, the knob 22 can be fixedly connected to the gear 21, and the knob 22 can be directly exposed. See also Figure 4 When the nose pads are too loose, that is, when the distance between the left nose pad 12 and the right nose pad 14 is too large, turn the knob 22 counterclockwise. The left rack portion 11 and the right rack portion 13 on both sides will move towards the middle at the same time. At the same time, the left rack portion 11 and the right rack portion 13 can respectively drive the left nose pad 12 and the right nose pad 14 to move towards the middle, so as to adjust the distance between the left nose pad 12 and the right nose pad 14 to a suitable spacing.

[0065] See Figure 5 When the nose pads are too tight, that is, when the distance between the left nose pad 12 and the right nose pad 14 is small, turning the knob 22 clockwise will cause the left rack portion 11 and the right rack portion 13 on both sides to move to the sides simultaneously. At the same time, the left rack portion 11 and the right rack portion 13 can respectively drive the left nose pad 12 and the right nose pad 14 to move away from each other, so as to widen the nose pads and achieve the purpose of flexibly adjusting the distance between the left nose pad 12 and the right nose pad 14.

[0066] Optionally, see Figure 8 and Figure 9 The adjustment unit 2 further includes a reset member 23, which is connected to the gear 21;

[0067] When the gear 21 is in the second position, the reset member 23 is compressed and can drive the gear 21 to reset from the second position to the first position.

[0068] Specifically, when the gear 21 is in the first position, it can be used to adjust the left nose pad 12 and the right nose pad 14 to move closer to each other; when the gear 21 is in the second position, it can be used to adjust the left nose pad 12 and the right nose pad 14 to move further apart from each other; and after the gear 21 is in the second position and the distance between the left nose pad 12 and the right nose pad 14 is adjusted to the correct position, the reset member 23 can drive the gear 21 to reset from the second position to the first position, so that the gear 21 can adjust the distance between the left nose pad 12 and the right nose pad 14 in the opposite direction in a timely manner.

[0069] In addition, while providing axial reset to the gear 21, the reset member 23 can also rotate with the gear 21 during its rotation, so that when the gear 21 reaches the set position, the reset member 23 provides circumferential reset to the gear 21, thereby preventing the gear 21 from continuing to rotate.

[0070] Optionally, see Figures 8 to 11 The adjustment unit 2 further includes a stop component 24, which cooperates with the gear 21;

[0071] When the gear 21 is in the first position, the stop assembly 24 can prevent the gear 21 from rotating clockwise;

[0072] When the gear 21 is in the second position, the stop assembly 24 can prevent the gear 21 from rotating counterclockwise.

[0073] Specifically, see Figure 8 When the nose pads are too loose, i.e., when the knob 22 is turned counterclockwise, the stop assembly 24 will retract, and the gear 21 will be in a first position, capable of adjusting the left nose pad 12 and the right nose pad 14 to be closer together, thereby adjusting the distance between the left nose pad 12 and the right nose pad 14 to a suitable spacing. At this time, the stop assembly 24 can restrict the clockwise rotation of the gear 21, that is, restrict the left nose pad 12 and the right nose pad 14 from moving away from each other.

[0074] When a user wears glasses, the left nose pad 12 and the right nose pad 14 will bear the outward force applied by the bridge of the nose, and the stop component 24 can ensure that the left nose pad 12 and the right nose pad 14 do not shift.

[0075] See Figure 9When the nose pads are too tight, press the knob 22 to push the gear 21 to slide to the rear end, and then turn the knob 22 clockwise. At this time, the stop component 24 will retract, and the gear 21 will be in the second position and can be used to adjust the distance between the left nose pad 12 and the right nose pad 14 to make the nose pads wider, so as to flexibly adjust the distance between the left nose pad 12 and the right nose pad 14.

[0076] After the gear 21 is in the second position and the distance between the left nose pad 12 and the right nose pad 14 is adjusted to the correct position, the gear 21 returns to the initial first position, that is, the knob 22 is in the initial unpressed state. At this time, since the stop component 24 can limit the clockwise rotation of the gear 21, the knob 22 and the gear 21 can only rotate counterclockwise to stably limit the left nose pad 12 and the right nose pad 14 in the adjusted position.

[0077] Optionally, see Figure 10 and Figure 11 The stop assembly 24 includes a stop tongue 241, which has a first segment and a second segment. The two sides of the first segment that are opposite to each other are a first smooth surface 2411 and a first stop surface 2412, respectively. The two sides of the second segment that are opposite to each other are a second smooth surface 2413 and a second stop surface 2414, respectively.

[0078] When the gear 21 is in the first position and rotates counterclockwise, the gear 21 engages with the first smooth surface 2411, and the first stop surface 2412 can block the gear 21 from rotating clockwise.

[0079] When the gear 21 is in the second position and rotates clockwise, the gear 21 engages with the second smooth surface 2413, and the second stop surface 2414 can prevent the gear 21 from rotating counterclockwise.

[0080] Specifically, see Figure 8 When the nose pads are too loose, that is, when the knob 22 is turned counterclockwise, the stop assembly 24 will retract due to the engagement of the gear 21 with the first smooth surface 2411. The gear 21 will be in the first position and can be used to adjust the left nose pad 12 and the right nose pad 14 to move closer to each other. The first stop surface 2412 prevents the gear 21 from rotating clockwise, which prevents the left nose pad 12 and the right nose pad 14 from moving outward, thus ensuring that the left nose pad 12 and the right nose pad 14 do not shift when worn.

[0081] See Figure 9When the nose pads are too tight, press the knob 22 to push the gear 21 to slide to the rear end, and then turn the knob 22 clockwise. Due to the cooperation between the gear 21 and the second smooth surface 2413, the stop assembly 24 will retract. The gear 21 is in the second position and can be used to adjust the distance between the left nose pad 12 and the right nose pad 14 to make the nose pads wider. At this time, the second stop surface 2414 can prevent the gear 21 from rotating counterclockwise, thus avoiding the reciprocating adjustment of the distance between the left nose pad 12 and the right nose pad 14.

[0082] Optionally, see Figure 10 The first smooth surface 2411 is an inclined surface or an arc surface.

[0083] Specifically, the arc surface can be an outwardly convex arc surface or an inwardly concave arc surface. When the gear 21 is in the first position and the knob 22 is rotated counterclockwise, since the first smooth surface 2411 is an inclined surface or an arc surface, the rotation of the gear 21 can force the stop assembly 24 to shift or retract, so as to ensure that the rotation of the gear 21 is not blocked by the first smooth surface 2411.

[0084] Similarly, the second smooth surface 2413 can also be an inclined surface or an arc surface. When the gear 21 is in the second position and the knob 22 is rotated clockwise, the rotation of the gear 21 can also force the stop assembly 24 to shift or move backward, so as to ensure that the rotation of the gear 21 is not blocked by the second smooth surface 2413.

[0085] Optionally, see 10, the first stop surface 2412 is a bent surface, and the bending angle of the bent surface is in the range of 60°-150°.

[0086] Specifically, when the gear 21 is in the first position and the knob 22 is rotated counterclockwise, the gear 21 will be blocked by the first stop surface 2412 when rotating clockwise because the first stop surface 2412 is a bent surface.

[0087] Similarly, the second stop surface 2414 can also be a bent surface. When the gear 21 is in the second position and the knob 22 is rotated clockwise, the counterclockwise rotation of the gear 21 will be blocked by the second stop surface 2414.

[0088] In addition, the bending angle formed by the first stop surface 2412 and the bending angle formed by the second stop surface 2414 can be the same; in one embodiment, the first stop surface 2412 is a right-angled bending surface with a bending angle of 90°, and the second stop surface 2414 is also a right-angled bending surface with a bending angle of 90°, so as to achieve the purpose of the stop component 24 preventing the knob 22 from reversing.

[0089] Optionally, see Figure 8 and Figure 9 The stop assembly 24 further includes a sleeve 242 and an elastic element 243, and the stop tongue 241 is connected to the sleeve 242 through the elastic element 243;

[0090] When the gear 21 engages with the first smooth surface 2411, the elastic element 243 is compressed;

[0091] When the gear 21 engages with the second smooth surface 2413, the elastic element 243 is compressed.

[0092] Specifically, the sleeve 242 can be connected to the eyeglass frame, and the stop tongue 241 is connected to the sleeve 242 via the elastic member 243. See also Figure 8 When the nose pads are too loose, that is, when the knob 22 is turned counterclockwise, the stop tongue 241 will retract into the sleeve 242 due to the abutment of the gear 21 and the first smooth surface 2411. The gear 21 is in the first position and can be used to adjust the left nose pad 12 and the right nose pad 14 to move closer to each other.

[0093] See Figure 9 When the nose pads are too tight, press the knob 22 to push the gear 21 to slide to the rear end, and then turn the knob 22 clockwise. Due to the cooperation between the gear 21 and the second smooth surface 2413, the stop tongue 241 will retract into the sleeve 242. The gear 21 is in the second position and can be used to adjust the left nose pad 12 and the right nose pad 14 to move away from each other.

[0094] The elastic element 243 ensures that the smooth surface of the stop tongue 241, while engaging with the gear 21, does not impede the unidirectional rotation of the gear 21. In other words, when the gear 21 rotates, it produces a clicking sound as it collides with the smooth surface of the stop tongue 241, allowing the user to clearly perceive the adjustment feedback process of the nose pad module.

[0095] See Figure 1 and Figure 2 This application provides a VR glasses, which includes a frame 100 and the nose pad module.

[0096] The nose pad module is connected to the eyeglass frame 100.

[0097] Specifically, the left nose pad 12 of the VR glasses is connected to the left rack portion 11, and the right nose pad 14 is connected to the right rack portion 13; the adjustment unit 2 includes a gear 21, the opposite sides of which mesh with the left rack portion 11 and the right rack portion 13 respectively, so that when the gear 21 rotates, the left nose pad 12 and the right nose pad 14 can move closer to each other or further away from each other, thereby improving the applicability and wearing comfort of the VR glasses.

[0098] Optionally, see Figure 2 and Figure 3 The frame 100 includes a front frame 101 and a rear frame 102. The front frame 101 and the rear frame 102 are fastened together to form a receiving cavity. The rear frame 102 is provided with a left sliding groove 1021 and a right sliding groove 1022.

[0099] The left rack portion 11 and the right rack portion 13 are located in the receiving cavity, and the left nose pad 12 and the right nose pad 14 extend from the rear frame 102 through the left sliding groove 1021 and the right sliding groove 1022, respectively.

[0100] Specifically, when the gear 21 simultaneously drives the left rack portion 11 and the right rack portion 13 to move, the left rack portion 11 can drive the left nose pad 12 to slide along the left slide groove 1021, and the right rack portion 13 can drive the right nose pad 14 to slide along the right slide groove 1022. This allows the distance between the left nose pad 12 and the right nose pad 14 to be adjusted as they move closer or further apart, thereby achieving a comfortable fit for the user.

[0101] In addition, the VR glasses also include temples 200, which are connected to both sides of the frame 100 to facilitate wearing the VR glasses.
