As shown in fig. 1-4, the present disclosure provides a head-mounted adjustment mechanism.
The head-mounted adjusting mechanism comprises an adjusting mechanism base 1, an adjusting piece 2 and a positioning assembly 3. The adjusting mechanism base 1 can be connected with the main body of the head-mounted intelligent equipment. The adjusting member 2 may be coupled to the head. The adjusting mechanism base 1 is provided with a positioning member mounting portion 111, and the positioning member mounting portion 111 can be used for mounting the positioning member 31.
The adjusting piece 2 is connected with the adjusting mechanism base 1 in a sliding fit manner, and a positioning piece matching part 21 is arranged on the adjusting piece 2. The positioning member engaging portion 21 can engage with the positioning member 31 to position or release the adjusting member 2.
The positioning assembly 3 comprises a positioning piece 31, and a mounting part 311 and a positioning part 312 are arranged on the positioning piece 31. The positioning member mounting portion 111 cooperates with the mounting portion 311 to mount the positioning member 31 on the adjustment mechanism base 1 and restrict the degree of freedom of the positioning member 31 in the direction in which the adjustment member 2 moves, so that the positioning member 31 cannot move in the direction in which the adjustment member 2 moves during use of the head-mounted adjustment mechanism.
The engagement between the retainer mounting portion 111 and the mounting portion 311 can be achieved in a variety of ways. For example, the mounting portion 311 is a protrusion on the positioning member 31, and the positioning member mounting portion 111 is a groove on the adjustment mechanism base 1, and the protrusion is adapted to the groove, so that the positioning member 31 can only move along the depth direction of the positioning member mounting portion 111. For another example, the mounting portion 311 is a tubular structure on the positioning member 31, and the positioning member mounting portion 111 is a columnar protrusion on the adjustment mechanism base 1, and the tubular structure is slidably engaged with the columnar protrusion, so that the positioning member 31 can only move along the length direction of the positioning member mounting portion 111. For another example, the mounting portion 311 is a clamping pin on the positioning member 31, and the positioning member mounting portion 111 is a clamping groove on the adjusting mechanism base 1, and the clamping pin is matched with the clamping groove, so that the positioning member 31 can only move along the depth direction of the positioning member mounting portion 111.
The positioning member 31 has a positioning state and a release state.
When the positioning member 31 is in the positioning state, the positioning portion 312 is engaged with the positioning member engaging portion 21 to position the adjustment member 2.
The engagement between the positioning portion 312 and the positioning member engaging portion 21 may be achieved in a variety of ways. For example, the positioning portion 312 is a protrusion on the positioning member 31, the positioning member matching portion 21 is a groove on the adjusting member 2, and by providing a plurality of grooves with different positions on the adjusting member 2, the positioning portion 312 can be adjusted to match with the different grooves, so as to position the adjusting member 2 at different positions. For another example, the positioning portion 312 is a tooth or a rack on the positioning member 31, the positioning member mating portion 21 is a rack on the adjusting member 2, and the adjusting member 2 can be positioned at different positions by adjusting the mating position of the positioning portion 312 on the positioning member mating portion 21.
When the retainer 31 is in the released state, the retainer 312 is separated from the retainer engaging portion 21 to release the regulator 2. When the positioning portion 312 is separated from the positioning member engaging portion 21, the adjusting member 2 can slide freely with respect to the adjusting mechanism base 1, thereby achieving adjustment of the head-wearing size.
The switching of the positioning member 31 between the positioning state and the release state may be achieved by manually applying a force to the positioning member 31 by a user, or by driving the positioning member 31 by an electric driving mechanism.
In use, the user can adjust the positioning portion 312 of the positioning member 31 to be separated from the positioning member engaging portion 21 of the adjusting member 2, and the positioning member 31 is in the released state, and the adjusting member 2 can freely slide relative to the adjusting mechanism base 1, so that the user can adjust the head wear to a comfortable position suitable for the head. The user can then adjust the positioning portion 312 of the positioning member 31 to be engaged with the positioning member engaging portion 21 of the adjusting member 2, and the positioning member 31 is in the positioning state, and the position of the adjusting member 2 is fixed, so that the size of the head wear is not changed.
When the positioning piece 31 is in a positioning state, the position of the adjusting piece 2 on the adjusting mechanism base 1 is fixed, and the size of the head wear is not adjustable; when the positioning member 31 is in the released state, the adjusting member 2 can move relative to the adjusting mechanism base 1, so that the adjustment of the size of the head wear is realized. The head-mounted adjusting mechanism can achieve adjustment of the head-mounted quickly and flexibly.
Moreover, the head-mounted adjusting mechanism integrates the mounting part 311 and the positioning part 312 on the positioning piece 31, so that the mounting part 311 and the positioning part 312 are positioned on the same component, the thickness of the head-mounted adjusting mechanism is effectively reduced, and the use experience of a user is improved.
Optionally, the positioning assembly 3 further comprises an elastic member 32. The elastic member 32 may provide the elastic force toward the adjusting member 2 to the positioning member 31, and under the action of the elastic force, the positioning portion 312 of the positioning member 31 may be engaged with the positioning member engaging portion 21 of the adjusting member 2, so that the user needs to overcome the elastic force of the elastic member 32 to separate the positioning portion 312 from the positioning member engaging portion 21. The elastic member 32 may be, for example, a spring plate or a spring. The adjustment mechanism base 1 is provided with an elastic member mounting portion 112 for mounting the elastic member 32. The provision of the elastic member 32 of the present disclosure is advantageous for improving the use experience of the head-mounted adjustment mechanism.
The mounting manner of the elastic member 32 may be different according to different structures or different types of elastic members 32, and the structure of the elastic member mounting portion 112 may be selected in various ways. For example, when the elastic member 32 is a compression spring, the elastic member mounting portion 112 may be a columnar protrusion on the base 1 of the adjusting mechanism, the compression spring may be sleeved on the columnar protrusion, and one end of the compression spring abuts against the positioning member 31. For another example, when the elastic member 32 is a compression spring, one end of the compression spring may be injection molded on the adjustment mechanism base 1, and the other end of the compression spring may abut against the positioning member 31. For another example, when the elastic member 32 is a spring, the elastic member mounting portion 112 may be a groove on the base 1 of the adjusting mechanism, one end of the spring may be fixed in the groove by injection molding, and the other end of the spring abuts against the positioning member 31.
Further, the elastic member 32 is a compression spring. The ends of the compression spring bear against the retainer 31. Such an elastic member 32 is inexpensive and easy to assemble with other components.
Further, the elastic member mounting portion 112 is an annular groove on the base 1 of the adjusting mechanism, the center of the annular groove has a hollow columnar protrusion, and the elastic member 32 is sleeved outside the columnar protrusion. The positioning member 31 has a positioning post 313, and the positioning post 313 is slidably engaged with the inner wall of the columnar boss, that is, the positioning post 313 is inserted into the hollow portion of the elastic member mounting portion 112. This arrangement is advantageous in improving the compactness of the structure of the head-mounted adjusting mechanism and reducing the thickness of the head-mounted adjusting mechanism. Furthermore, the provision of the stopper post 313 is also advantageous in order to better restrict the degree of freedom of the positioning member 31 in the direction in which the adjustment member 2 moves.
When the positioning member 31 needs to be adjusted to the release state, the user needs to overcome the elastic force of the elastic member 32 to apply a force to the positioning member 31 to drive the positioning member 31 to move, so that the positioning portion 312 of the positioning member 31 is separated from the positioning member matching portion 21 of the adjusting member 2. When the user stops applying the force to the positioning member 31, the positioning member 31 can automatically move toward the adjusting member 2 under the elastic force of the elastic member 32, so that the positioning portion 312 is engaged with the positioning member engaging portion 21.
Further, the positioning assembly 3 further comprises a key 33. The key 33 has a pressing portion 331 and a pressing protrusion 332. The adjusting mechanism base 1 is provided with a key hole 120, and the key hole 120 can expose the pressing part 331, so that a user can conveniently press the key 33. The adjusting member 2 is provided with a sliding fit hole 22, and the positioning member fitting portion 21 is located on one side of the adjusting member 2 adjacent to the elastic member mounting portion 112. The pressing protrusion 332 passes through the sliding fit hole 22, and the pressing protrusion 332 presses against the surface of the positioning member 31, so that the key 33 can apply a force to the positioning member 31. The positioning member 31 can move away from the positioning member mating portion 21 against the elastic force of the elastic member 32 under the action of the force transmitted from the key 33, so that the positioning member 32 enters the release state from the positioning state.
When the user presses the key 33 by the pressing portion 331, the pressing protrusion 332 of the key 33 applies a force to the positioning member 31, and the positioning member 31 moves against the elastic force of the elastic member 32, and at this time, the positioning member 32 enters a released state from a positioned state.
When the positioning member 31 is in the released state, the positioning portion 312 of the positioning member 31 is separated from the positioning member engaging portion 21 of the adjusting member 2, the adjusting member 2 is slidable relative to the adjusting mechanism base 1, and the user can adjust the head wear to a comfortable position for the head.
When the user stops pressing the key 33, the positioning member 31 moves toward the adjusting member 2 by the elastic force of the elastic member 32, so that the positioning portion 312 of the positioning member 31 is engaged with the positioning member engaging portion 21 of the adjusting member 2, the positioning member 31 is adjusted from the released state to the positioned state, the position of the adjusting member 2 is fixed, and the size of the head-wear is not changed any more.
Further, the adjustment mechanism base 1 includes a base main body 11 and a base cover plate 12. The base main body 11 is detachably connected with the base cover plate 12, and the detachable connection can be realized by means of a buckle connection or a bolt connection. The adjusting member 2 is connected with the base body 11 in a sliding fit manner, the positioning member mounting portion 111 and the elastic member mounting portion 112 are both located on the base body 11, and the key hole 120 is located on the base cover plate 12. The parts of the head-mounted adjusting mechanism can be conveniently assembled together.
In a specific implementation, the base body 11 may be provided with a sliding slot for sliding the adjusting member 2, and the adjusting member 2 may move relative to the adjusting mechanism base 1 through sliding fit with the sliding slot. More specifically, the regulating member 2 has a plate-like structure, and an edge of the plate-like structure is slidably fitted with a slide groove on the base body 11.
Further, the base body 11 is provided with an adjustment restricting portion 113. The adjustment restricting portion 113 cooperates with the adjustment member 2 to restrict the sliding stroke of the adjustment member 2. When the regulating member 2 slides in the regulating mechanism base 1 to the regulating limiting portion 113, the regulating member 2 stops moving. The adjustment limiting portion 113 may be, for example, a protrusion on the adjustment mechanism base 1, and when the adjustment member 2 slides in the adjustment mechanism base 1 until it abuts against the protrusion, the adjustment member 2 stops sliding.
In particular, two regulating member limiting portions 113 may be disposed on the base main body 11, where the two regulating member limiting portions 113 are respectively located at two ends of the base main body 11 along the sliding direction of the regulating member 2, so that the sliding of the regulating member 2 on the base main body 11 can be effectively controlled, and the user experience is good.
Alternatively, the positioning portion 312 is a tooth on the positioning member 31, and the positioning mating portion 21 is a rack on the surface of the adjusting member 2. The positioning member 31 can be positioned at different positions on the adjusting member 2 when the teeth are engaged with different tooth grooves of the rack. According to the actual requirements, the number of the positioning portions 312 can be set according to the actual requirements.
In one embodiment, the positioning member 31 has a disk-like shape, and two positioning portions 312 are respectively located at both ends of one diameter of the positioning member 31, and two mounting portions 311 are respectively located at both ends of the other diameter perpendicular to the above diameter.
