[0030] With the rapid development of electronic information, various types of electronic products are emerging. For the convenience of wearing, many electronic products are produced in head-mounted style, including virtual reality headsets, augmented reality headsets, headphones, etc. Such head-mounted electronic products usually include a product body and a headband connected to the product body. Given that the head circumferences of different users are different, in order to adapt to different users, the length of the headband needs to be adjusted to adjust the wearing tightness of the head-mounted electronic device.

[0031] Existing head-mounted electronic devices usually use a buckle structure to adjust the length of the headband, which requires pulling in the extension direction of the headband. If the force is small, it cannot be pulled, and if the force is large, it will be over-adjusted, making adjustment inconvenient.

[0032] In view of this, the present invention provides an adjustment component and a head-mounted electronic product. Figures 1 to 6 This is an embodiment of the head-mounted electronic product provided by the present invention.

[0033] It should be noted that the present invention does not specifically limit the type of the head-mounted electronic product. The head-mounted electronic product can be any head-mounted electronic product, such as a virtual reality head-mounted device, an augmented reality head-mounted device, a headset, etc. The head-mounted electronic product is illustrated as a headset in the accompanying drawings.

[0034] In the embodiments of the present invention, see Figures 1 to 6 , see Figure 5 The adjustment component 100 is used for a head-mounted electronic product 1000. The adjustment component 100 includes a mounting seat 1, a telescopic portion 2 and an adjustment mechanism. The telescopic portion 2 is used to be arranged at one end of the headband 200 of the head-mounted electronic product 1000, and the telescopic portion 2 extends along a first direction. The telescopic portion 2 is movably installed on the mounting seat 1 along the first direction; the adjustment mechanism includes a rack portion 3 arranged on the telescopic portion 2 and extending along the first direction, and a driving gear 4 engaged with the rack portion 3 and with a rotating shaft extending along a second direction (for ease of understanding, in the accompanying drawings, it is recommended to understand that after the headphone 1100 is worn, the up and down direction of the user corresponds to the first direction, the left and right direction of the user corresponds to the second direction, and the front and back direction of the user corresponds to the third direction), and an adjustment portion 5 rotatably installed on the mounting seat 1 and capable of driving the driving gear 4 to rotate, and the second direction intersects with the first direction.

[0035] In the technical solution of the present invention, when adjusting the wearing tightness of the head-mounted electronic product 1000, the adjusting part 5 is rotated, and the adjusting part 5 drives the driving gear 4 to rotate, and the driving gear 4 drives the rack part 3 to move along the first direction, so that the telescopic part 2 moves along the first direction, thereby adjusting the length of the headband 200. In this way, the length of the headband 200 can be adjusted by rotating the adjusting part 5, and the operation is simple, so that the length adjustment of the headband 200 is simple and convenient, and the user experience is improved.

[0036] The present invention does not limit the specific manner in which the adjustment portion 5 drives the drive gear 4 to rotate. For example, the adjustment portion 5 is a knob fixedly connected to the rotating shaft of the drive gear 4. The knob is coaxially arranged with the drive gear 4. Rotating the knob can rotate the rotating shaft of the drive gear 4, thereby driving the drive gear 4 to rotate. In this embodiment, the adjustment mechanism also includes an inner ring gear 6, which is arranged on the periphery of the drive gear 4 and meshes with the drive gear 4. The adjustment portion 5 is drivingly connected to the inner ring gear 6 to drive the drive gear 4 to rotate by driving the inner ring gear 6. In this way, by driving the drive gear 4 to rotate by the inner ring gear 6, accelerated transmission can be achieved. The adjustment portion 5 can achieve a longer headband 200 length adjustment by rotating a smaller angle, thereby increasing the adjustment sensitivity and further improving the user experience.

[0037] In this embodiment, rack portions 3 are provided on both sides of the telescopic portion 2, wherein one of the rack portions 3 is meshed with the driving gear 4; the adjusting mechanism further includes a transmission gear set provided between the inner gear ring 6 and the other rack portion 3, the transmission gear set including a first gear 7 meshed with the inner gear ring 6, and a second gear 8 meshed with the first gear 7 and the other rack portion 3. When the adjusting portion 5 drives the inner gear ring 6 to rotate clockwise, the inner gear ring 6 drives the driving gear 4 and the first gear 7 to rotate clockwise, and the first gear 7 drives the second gear 8 to rotate counterclockwise. The driving gear 4 and the second gear 8 can synchronously drive the telescopic portion 2 to move along the first direction ( Figure 5 On the contrary, when the adjusting portion 5 drives the inner gear ring 6 to rotate counterclockwise, the driving gear 4 rotates counterclockwise and the second gear 8 rotates clockwise. The driving gear 4 and the second gear 8 can synchronously drive the telescopic portion 2 to move along the first direction ( Figure 5 In this way, the telescopic portion 2 is subjected to balanced force, avoiding offset and jamming between the telescopic portion 2 and the driving gear 4 during adjustment, making the adjustment process of the headband 200 smoother and more stable, further improving the user experience.

[0038] In order to avoid misoperation, in this embodiment, see Figure 3 、 Figure 4 and Figure 6 The mounting seat 1 and the adjusting portion 5 are provided with a limited matching portion 9 and a limiting portion 10, respectively. The limited matching portion 9 and the limiting portion 10 have a locked state and an unlocked state. In the locked state (see Figure 4 ), the limiting matching portion 9 and the limiting portion 10 cooperate with each other to limit the rotation of the adjusting portion 5. When in the unlocked state (see Figure 6), the limiting fitting part 9 and the limiting part 10 are released from cooperation, and the adjusting part 5 can rotate freely. In this way, when it is necessary to adjust the wearing tightness of the head-mounted electronic product 1000, the limiting fitting part 9 and the limiting part 10 are released from cooperation, and the adjusting part 5 is rotated to adjust the length of the headband 200. After the length of the headband 200 is adjusted, the limiting fitting part 9 and the limiting part 10 cooperate with each other to limit the rotation of the adjusting part 5. During normal wearing, the adjusting part 5 is stably positioned to avoid misoperation and improve the reliability of the product.

[0039] The present invention does not limit the specific arrangement of the limiting portion 10 and the limiting matching portion 9. The limiting portion 10 is a plurality of first limiting holes arranged in an array, and the limiting matching portion 9 is a second limiting hole. The first limiting holes and the second limiting holes at different positions correspond to each other and fasteners are movably inserted therethrough to achieve positioning. In this embodiment, the adjustment portion 5 is movably arranged in the second direction; one of the limiting matching portion 9 and the limiting portion 10 is a limiting rib, and the other is a limiting groove. In this way, by changing the position of the adjustment portion 5, the relative position of the limiting rib and the limiting groove is changed. The limiting rib and the limiting groove have a locked state in which the limiting rib is located in the limiting groove, and an unlocked state in which the limiting rib is removed from the limiting groove. No additional accessories are required, the structure is simple, and the matching is reliable.

[0040] The present invention does not limit the specific configuration of the inner gear ring 6 and the adjusting portion 5. For example, the adjusting portion 5 and the inner gear ring 6 are integrally configured into a ring shape, the inner ring of the ring shape is provided with a gear ring to form the inner gear ring 6, and the outer side of the ring shape forms the adjusting portion 5. In this embodiment, see Figure 2 and Figure 3 The adjusting portion 5 and the inner gear ring 6 are provided separately. The adjusting portion 5 and the inner gear ring 6 are provided with a driving portion 11 and a driving mating portion 12 respectively. The driving portion 11 and the driving mating portion 12 cooperate with each other to limit the relative rotation of the adjusting portion 5 and the inner gear ring 6. This reduces the difficulty of production and helps reduce production costs.

[0041] In this embodiment, one of the driving portion 11 and the driving engagement portion 12 is a driving rib, and the other is a driving groove. The adjusting portion 5 is movably arranged in the second direction. During the movable travel of the adjusting portion 5 along the second direction, the driving rib is at least partially located in the driving groove. In this way, it is possible to ensure that the driving rib and the driving groove always cooperate with each other to limit the relative rotation of the adjusting portion 5 and the internal gear. The internal gear can be fixed in the second direction and stably mesh with the driving gear 4. At the same time, the movable arrangement of the adjusting portion 5 in the second direction facilitates the provision of a limiting structure between the adjusting portion 5 and the mounting seat 1, such as the limiting rib and limiting groove described in the above embodiment. Of course, in this embodiment, no specific limitation is made to this. It can be understood that when the limiting rib and limiting groove described in the above embodiment exist at the same time as the driving rib and driving groove in this embodiment, the fitting depth between the driving groove and the driving rib is greater than the fitting depth between the limiting rib and the limiting groove, so that when the limiting rib is disengaged from the limiting groove, the driving rib is still partially located in the driving groove, that is, when the limiting rib and the limiting groove are in the locked state and the unlocked state, the driving rib and the driving groove always maintain a mutually fitting state, thereby ensuring the driving connection between the adjusting part 5 and the inner gear ring 6.

[0042] In order to avoid over-adjustment, in this embodiment, see Figure 5 One of the telescopic part 2 and the mounting seat 1 is provided with an elongated slide groove 13, and the other is provided with a slider 14. The slider 14 cooperates with the elongated slide groove 13 to limit the movable stroke of the telescopic part 2 along the first direction, thereby avoiding excessive adjustment of the headband 200. At the same time, the elongated slide groove 13 guides the slider 14, which can make the movement of the telescopic part 2 more stable, thereby improving the user experience.

[0043] The present invention further provides a head-mounted electronic product 1000, comprising a headband 200 and the adjustment assembly 100 as described above. The head-mounted electronic product 1000 adopts all of the above embodiments and therefore has at least the technical effects brought about by all of the above technical solutions, which will not be described one by one here.

[0044] In this embodiment, the head-worn electronic product 1000 is a headset 1100, which includes two main bodies 300. The ends of the headband 200 are connected to the main bodies 300 via the adjustment assembly 100. In this way, the length of the headband 200 can be adjusted at both ends, which improves the adjustment effect.

[0045] The present invention does not limit the specific structure of the main body 300. In one embodiment, the main body 300 includes a shell 310 and a buffer structure 320 connected to the shell 310. The sound unit of the headset 1100 (not shown in the figure) is installed in the shell 310, which does not interfere with the adjustment component 100, which is conducive to improving the reliability of the product; the buffer structure 320 improves wearing comfort, which is conducive to further improving the user experience.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
