Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to an orientation adjustment mechanism. Background Technology

[0002] In existing smart wearable devices, the display is usually designed as a detachable structure to adjust its orientation. However, this design makes it time-consuming, laborious, and complicated to adjust the orientation of the display. It is also relatively loose during positioning and assembly, making it impossible to lock and position it securely and reliably. It requires the cooperation of other components, which affects the user experience. Summary of the Invention

[0003] The purpose of this invention is to provide an orientation adjustment mechanism that enables convenient orientation adjustment and secure locking after adjustment.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Orientation adjustment mechanism, including:

[0006] Support;

[0007] A movable seat is rotatably mounted on the support seat, and a support protrusion is provided on the movable seat;

[0008] A locking component is disposed between the support seat and the movable seat, including two rollers and two elastic elements. In the circumferential direction of the movable seat, the support protrusion is disposed between the two rollers, and an elastic element is sandwiched between each roller and the support protrusion. When the roller abuts against the support seat and the movable seat under the support of the elastic element, it is in a locked state.

[0009] An adjusting seat is rotatably mounted on the support seat. The adjusting seat is provided with an adjusting protrusion. When the adjusting seat rotates relative to the support seat, the adjusting protrusion can push the roller on one side of the supporting protrusion to move toward the supporting protrusion. When the roller moves toward the supporting protrusion, it exits the locked state.

[0010] Preferably, the movable seat is provided with a guide surface, and the guide surface and the roller correspond one-to-one. Along the direction away from the support protrusion, the guide surface gradually approaches the bearing seat. In the locked state, the roller abuts against the guide surface.

[0011] Preferably, the movable seat is provided with positioning protrusions, and the positioning protrusions correspond one-to-one with the rollers. The guide surface is located between the positioning protrusions and the support protrusions. The adjusting protrusion is provided with a positioning part. When the positioning part abuts against the positioning protrusion, the rollers are in an unlocked and stopped state.

[0012] Preferably, the adjusting protrusion is further provided with a pushing part, and when the roller is in the unlocked stop state, the pushing part extends between the bearing seat and the guide surface.

[0013] Preferably, the movable seat is provided with limiting protrusions, the limiting protrusions and the rollers are in one-to-one correspondence and are located between the guide surface and the support protrusions, and the elastic element is located between the limiting protrusions and the bearing seat.

[0014] Preferably, the support seat is provided with a receiving groove, the movable seat is located in the receiving groove, the locking component is sandwiched between the inner wall of the receiving groove and the outer wall of the movable seat, the adjusting seat is provided with a fitting groove, the fitting groove is fitted onto the support seat, and the adjusting protrusion is provided at the bottom of the fitting groove and extends between the inner wall of the receiving groove and the outer wall of the movable seat.

[0015] Preferably, the bottom of the receiving groove is provided with a bearing shaft, and the movable seat is sleeved on the bearing shaft.

[0016] Preferably, the inner wall of the receiving groove is provided with a first support ring, and the outer wall of the movable seat is provided with a second support ring. In the axial direction of the movable seat, the locking component abuts against the first support ring and the second support ring.

[0017] Preferably, the roller has a cylindrical structure, and the axial direction of the roller is parallel to the axial direction of the movable seat.

[0018] Preferably, the movable seat is provided with a plurality of support protrusions evenly distributed in the circumferential direction, each support protrusion is configured with a locking component, and each locking component is configured with two adjustment protrusions.

[0019] The beneficial effects of this invention are:

[0020] When the adjusting seat rotates in one direction relative to the support seat, the adjusting protrusion pushes one of the rollers in the locking assembly toward the supporting protrusion. The other roller in the locking assembly moves toward the supporting protrusion under the action of friction, compressing the two elastic elements in the locking assembly. The two rollers in the locking assembly then disengage from the locked state, allowing the adjusting seat to rotate relative to the support seat. This facilitates the adjustment seat's orientation adjustment. After adjustment, the two rollers in the locking assembly return to the locked state under the support of the elastic elements, enabling safe and automatic locking. This ensures that the adjusting seat is reliably positioned and fixed on the support seat. The two rollers and two elastic elements in the locking assembly cooperate with each other, allowing the adjusting seat to achieve orientation adjustment and automatic locking when rotating relative to the support seat clockwise or counterclockwise.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1-7 As shown, the present invention provides an orientation adjustment mechanism, including a support seat 1, a movable seat 2, a locking component 3, and an adjustment seat 4. The movable seat 2 is rotatably mounted on the support seat 1. The movable seat 2 is provided with a support protrusion 21. The locking assembly 3 is located between the support seat 1 and the movable seat 2, and includes two rollers 31 and two elastic elements 32. In the circumferential direction of the movable seat 2, the support protrusion 21 is located between the two rollers 31. An elastic element 32 is sandwiched between each roller 31 and the support protrusion 21. When the roller 31 abuts against the support seat 1 and the movable seat 2 under the support of the elastic element 32, it is in a locked state. In the locked state, the movable seat 2 is locked to the support seat 1. The adjusting seat 4 is rotatably mounted on the support seat 1. The adjusting seat 4 is provided with an adjusting protrusion 41. When the adjusting seat 4 rotates relative to the support seat 1, the adjusting protrusion 41 can push the roller 31 on one side of the support protrusion 21 to move toward the support protrusion 21. When the roller 31 moves toward the support protrusion 21, it exits the locked state. When it exits the locked state, the movable seat 2 can rotate relative to the support seat 1.

[0042] In this invention, when the adjusting seat 4 rotates relative to the bearing seat 1 in one direction, the adjusting protrusion 41 pushes one of the rollers 31 in the locking assembly 3 towards the supporting protrusion 21. The other roller 31 in the locking assembly 3 moves towards the supporting protrusion 21 under the action of friction, compressing the two elastic elements 32 in the locking assembly 3. The two rollers 31 in the locking assembly 3 then exit the locked state, thereby enabling the adjusting seat 4 to drive the movable seat 2 to rotate relative to the bearing seat 1, facilitating the adjustment seat 4 to perform orientation adjustment. After the adjustment is completed, the two rollers 31 in the locking assembly 3 return to the locked state under the support of the elastic elements 32, enabling safe and automatic locking. This ensures that the adjusting seat 4 is reliably positioned and fixed on the bearing seat 1. The two rollers 31 and the two elastic elements 32 in the locking assembly 3 cooperate with each other, enabling the adjusting seat 4 to achieve orientation adjustment and automatic locking when rotating relative to the bearing seat 1 in both clockwise and counterclockwise directions.

[0043] Specifically, the movable seat 2 is provided with a guide surface 22, which corresponds one-to-one with the roller 31. Along the direction away from the support protrusion 21, the guide surface 22 gradually approaches the support seat 1. In the locked state, the roller 31 abuts against the guide surface 22. By providing the guide surface 22, the roller 31 and the elastic element 32 cooperate with each other, and the locking of the support seat 1 and the movable seat 2 can be easily achieved.

[0044] More specifically, the movable seat 2 is provided with positioning protrusions 23, which correspond one-to-one with rollers 31. The guide surface 22 is located between the positioning protrusions 23 and the support protrusions 21. The adjusting protrusion 41 is provided with a positioning part 411. When the positioning part 411 abuts against the positioning protrusion 23, the roller 31 is in an unlocked and stopped state. In the unlocked and stopped state, the roller 31 is at its extreme position close to the support protrusion 21, and the adjusting seat 4 can drive the movable seat 2 to rotate synchronously. The above arrangement avoids excessive pushing of the adjusting protrusion 41 against the roller 31 and ensures more precise positioning adjustment of the adjusting seat 4.

[0045] Specifically, the adjusting protrusion 41 is also provided with a pushing part 412. When the roller 31 is in the unlocked and stopped state, the pushing part 412 extends between the bearing seat 1 and the guide surface 22. By providing the pushing part 412, it is ensured that the adjusting protrusion 41 can push the roller 31 past the positioning protrusion 23.

[0046] More specifically, the movable seat 2 is provided with limiting protrusions 24, which correspond one-to-one with the rollers 31 and are located between the guide surface 22 and the support protrusions 21. The elastic element 32 is located between the limiting protrusions 24 and the bearing seat 1. By providing the limiting protrusions 24, the elastic element 32 can be supported, and the rollers 31 can be prevented from moving excessively and failing to return to their original position.

[0047] In this embodiment, each support protrusion 21 corresponds to two rollers 31, and each roller 31 corresponds to a positioning protrusion 23, a guide surface 22, a limiting protrusion 24, and a support protrusion 21. In the circumferential direction of the movable seat 2, the guide surface 22 is located between the positioning protrusion 23 and the limiting protrusion 24, and the limiting protrusion 24 is located between the guide surface 22 and the support protrusion 21. The elastic element 32 is a spring. In other embodiments, the elastic element 32 can also be a rubber rod, as long as it can support the rollers 31.

[0048] Specifically, the support base 1 is provided with a receiving groove 11, the movable seat 2 is located in the receiving groove 11, the supporting protrusion 21 is provided on the outer wall of the movable seat 2, the locking component 3 is sandwiched between the inner wall of the receiving groove 11 and the outer wall of the movable seat 2, and the adjusting seat 4 is provided with a fitting groove 42, which is fitted onto the support base 1. The adjusting protrusion 41 is located at the bottom of the fitting groove 42 and extends between the inner wall of the receiving groove 11 and the outer wall of the movable seat 2. This arrangement ensures that the locking component 3 is enclosed by the support base 1 and the adjusting seat 4, preventing exposure and making operation safer.

[0049] More specifically, a bearing shaft 12 is provided at the bottom of the receiving groove 11, and the movable seat 2 is sleeved on the bearing shaft 12. The above arrangement allows the movable seat 2 to rotate safely and reliably on the bearing seat 1, and prevents the movable seat 2 from deviating from the rotation axis when the roller 31 abuts and locks against it.

[0050] In this embodiment, among the support protrusion 21, guide surface 22, positioning protrusion 23, and limiting protrusion 24, the gap between the support protrusion 21 and the inner wall of the receiving groove 11 is the smallest, set as L1; the gap between the guide surface 22 and the inner wall of the receiving groove 11 is the largest, set as L2; ​​and the gaps between the positioning protrusion 23 and the limiting protrusion 24 and the inner wall of the receiving groove 11 are greater than L1 and less than L2.

[0051] More specifically, the inner wall of the receiving groove 11 is provided with a first support ring 13, and the outer wall of the movable seat 2 is provided with a second support ring 25. In the axial direction of the movable seat 2, the locking component 3 abuts against the first support ring 13 and the second support ring 25. The above arrangement can reliably support the locking component 3, so that the locking component 3 is close to the adjusting protrusion 41 provided at the bottom of the mounting groove 42.

[0052] In this embodiment, the roller 31 has a columnar structure, and the axial direction of the roller 31 is parallel to the axial direction of the movable seat 2. One end faces the bottom of the mounting groove 42, and the other end faces the first support ring 13 and the second support ring 25, so that it is more balanced and reliable when moving. In addition, the gap between the positioning protrusion 23 and the limiting protrusion 24 and the inner wall of the receiving groove 11 is smaller than the diameter of the roller 31, so that the roller 31 can be limited.

[0053] Specifically, multiple support protrusions 21 are evenly distributed around the circumference of the movable seat 2. Each support protrusion 21 is equipped with a locking component 3, and each locking component 3 is equipped with two adjusting protrusions 41. This arrangement makes the force distribution between the support seat and the movable seat 2, as well as between the adjusting seat 4 and the movable seat 2, more stable.

[0054] In this embodiment, the movable seat 2 is provided with two support protrusions 21, which are located on opposite sides of the movable seat 2.

[0055] The orientation adjustment mechanism of the present invention can be applied to existing smart wearable devices, such as smartwatches and smart bracelets. When applied to a smartwatch, the support 1 is fixed on the dial and the display screen is fixed on the adjustment base 4. The orientation of the display screen can be adjusted by the user manually rotating the adjustment base 4, which makes it easier for the user to observe and use.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
