Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, in particular to an electronic equipment accessory. Background Art
[0002] With the popularity of electronic devices such as mobile phones and tablets, the use of accessories such as chargers, protective cases, and mobile power supplies is becoming more and more common. In order to enrich the functions of accessories, brackets are usually installed on the accessories to achieve the support function. The bracket includes a base and a support member. The support member rotates with the base so that the support member can rotate relative to the base to support the accessory. The base rotates with the accessory so that the base can drive the support member to rotate relative to the accessory to adjust the support direction and achieve the effect of horizontal support and vertical support.
[0003] In order to enhance the stability of the base in the supporting state, a limit piece is usually arranged on the base, and the base is provided with a limit hole corresponding to the limit piece, and the limit piece can be inserted into the limit hole or withdrawn from the limit hole to achieve the effect of limiting and releasing the limit.
[0004] However, the top and limiting hole of the existing limit piece are roughly hemispherical. After the limit piece is inserted into the limiting hole, the arc-shaped outer surface of the top of the limit piece fits with the inner wall of the limiting hole, and the contact area is large. As a result, when the base is rotated to withdraw the limit piece from the limiting hole, the friction between the limit piece and the base is large. Therefore, a large force is required to rotate the base, which also increases the wear. Moreover, after the limit piece is withdrawn from the limiting hole, as the base rotates, the top of the limit piece will still have a certain degree of wear, so that after the base is rotated a certain number of times, the limit piece cannot fit with the inner wall of the limiting hole when inserted into the limiting hole due to excessive wear, thereby affecting or losing the limiting effect. Utility Model Content
[0005] In view of this, the utility model provides a new electronic equipment accessory to solve the above problems.

DETAILED DESCRIPTION
[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0031] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0032] See also Figures 1 to 8 An electronic device accessory 10 provided by an embodiment of the utility model includes an accessory body 12 and a bracket 14. The accessory body 12 is used in conjunction with an electronic device, and its specific type is not limited, such as a protective case, a mobile power supply, a wireless charger, etc. The bracket 14 is connected to the accessory body 12 and is used to support the accessory body 12.
[0033] In this embodiment, the accessory body 12 is a wireless charger, and the bracket 14 is used to support the wireless charger at an angle on the desktop, thereby supporting the electronic device at an angle on the desktop, so that the user can watch videos while the electronic device is charging.
[0034] The bracket 14 includes a base 16 and a support member 18, wherein the base 16 is rotatably connected to the accessory body 12, and the support member 18 is rotatably connected to the base 16. After the support member 18 rotates relative to the base 16 by a certain angle, the support member 18 and the accessory body 12 form an angle, so that the support member 18 tilts to support the accessory body 12. During the rotation of the base 16 relative to the accessory body 12, the support member 18 is driven to rotate relative to the accessory body 12, thereby adjusting the position of the support member 18, thereby achieving the effect of adjusting the support direction, and at the same time, the support member 18 can adjust the support angle by rotating the support member 18 in different support directions.
[0035] A mounting hole 20 and a storage slot 22 are provided on one side of the accessory body 12. The base 16 is movably mounted in the mounting hole 20. The storage slot 22 is used to store the support member 18. When the support member 18 is needed, the support member 18 can be rotated out of the storage slot 22. When the support member 18 is not needed, the support member 18 can be stored in the storage slot 22 to reduce the abruptness of the bracket 14 and reduce the overall thickness and volume of the electronic device accessory 10. Specifically, the support member 18 and the storage slot 22 are both annular.
[0036] A hand grip 24 is provided on one side of the support member 18 away from the base 16 , and the hand grip 24 is connected to the storage slot 22 . The user can insert a finger into the hand grip 24 and press against the support member 18 , so that the user can easily rotate the support member 18 out of the storage slot 22 .
[0037] In one embodiment, the accessory body 12 includes a main body portion 26 and a fixing portion 28 . The main body portion 26 is provided with a mounting hole 20 and a receiving groove 22 . The base 16 is received in the mounting hole 20 . The fixing portion 28 is fixed to the mounting hole 20 and surrounds the outer side of the base 16 .
[0038] The specific method of fixing the fixing portion 28 to the main body 26 is not limited, for example, by a connector, adhesive, fixing structure, etc. In this embodiment, the fixing portion 28 is sandwiched between the base 16 and the main body 26, and a rotation-stopping recess 30 is provided on the outer side of the fixing portion 28, and a rotation-stopping protrusion 32 is correspondingly provided on the main body 26. The rotation-stopping protrusion 32 is located in the mounting hole 20, and the rotation-stopping protrusion 32 is inserted into the rotation-stopping recess 30, thereby forming a rotation-stopping effect on the main body 26 and the fixing portion 28 in the circumferential direction to prevent relative rotation.
[0039] Specifically, there are multiple anti-rotation protrusions 32 and anti-rotation recesses 30 in one-to-one correspondence, and multiple anti-rotation recesses 30 are arranged at intervals along the circumference of the fixing portion 28 , and each anti-rotation protrusion 32 is inserted into a corresponding anti-rotation recess 30 .
[0040] A first slot 34 is provided on the outer side of the base 16, and a second slot 36 is provided on the inner wall of the mounting hole 20 of the main body 26. The first slot 34 and the second slot 36 are spaced and opposite to each other. Both the first slot 34 and the second slot 36 are annular. The base 16 is connected to the main body 26 of the accessory body 12 through a connecting member 38. The connecting member 38 is annular, and its radial inner side is located in the first slot 34, and its radial outer side is located in the second slot 36, so as to limit the base 16 in the axial direction to prevent the base 16 from being separated from the accessory body 12. At the same time, the base 16 forms a rotational fit with the accessory body 12 in the circumferential direction, so that the base 16 can rotate relative to the accessory body 12. Specifically, the connecting member 38 is a component similar to a retaining spring, which has a certain elasticity and can be deformed during the assembly process to facilitate assembly.
[0041] In one embodiment, a limiting assembly 40 is provided between the base 16 and the accessory body 12. The limiting assembly 40 includes a limiting member 42 and an elastic member 44. The limiting member 42 is movably matched with the base 16. The elastic member 44 is located between the limiting member 42 and the base 16. A limiting space 46 that matches with the limiting member 42 is provided on the accessory body 12. Specifically, the fixing portion 28 of the accessory body 12 is annular and surrounds the outside of the base 16. The limiting space 46 is provided on the radial inner side of the fixing portion 28. In the process of rotating the base 16, the accessory body 12 will squeeze the limiting member 42 and compress and deform the elastic member 44, so that the limiting member 42 withdraws from the limiting space 46 and releases the limiting effect. When the limiting member 42 is inserted into the limiting space 46, the accessory body 12 forms a limiting effect on the base 16 through the limiting member 42, so as to enhance the stability of the base 16 at this position, thereby enhancing the stability of the support member 18 during the support process.
[0042] The limiting space 46 includes an opening 461 and a bottom 462 opposite to each other. The opening 461 is used for the limiting member 42 to pass through and move toward the bottom 462. When the limiting member 42 is inserted into the limiting space 46 under the action of the elastic member 44, the limiting member 42 is spaced from the bottom 462 of the limiting space 46. By forming a gap between the limiting member 42 and the bottom 462 of the limiting space 42, the contact area between the limiting member 42 and the accessory body 12 can be reduced, thereby reducing the friction between the limiting member 42 and the accessory body 12, thereby reducing the wear caused when the limiting member 42 withdraws from the limiting space 46, and also reducing the external force required to rotate the base 16, which is convenient for users to use; at the same time, the gap between the limiting member 42 and the inner wall of the limiting space 46 can also reduce the requirements for accuracy, and when the limiting member 42 is reduced in volume due to wear, the limiting member 42 can continue to move toward the bottom 462 to offset the influence of wear, ensure the limiting effect, and extend the service life of the bracket 14.
[0043] Specifically, the elastic member 44 is located on the side of the limiting member 42 away from the limiting space 46, and the elastic member 44 is a spring, and the two ends of the spring respectively press against the base 16 and the limiting member 42. When the base 16 is rotated, the base 16 squeezes the limiting member 42, and the limiting member 42 transmits the pressure to the spring, compressing the spring, and finally withdrawing the limiting member 42 from the limiting space 46. When the limiting member 42 rotates to the limiting space 46 following the base 16, the pressure of the accessory body 12 on the limiting member 42 disappears, and the limiting member 42 is automatically inserted into the limiting space 46 under the elastic force of the elastic member 44, forming a limiting effect.
[0044] In other embodiments, the limiting member 42 is disposed on the accessory body 12 , and the limiting space 46 is correspondingly disposed on the base 16 , which can also achieve a limiting effect. In this case, the elastic member 44 is located between the limiting member 42 and the accessory body 12 .
[0045] The specific number of the limiting spaces 46 is not limited. In this embodiment, the fixing portion 28 of the accessory body 12 is annular, and the fixing portion 28 surrounds the outside of the base 16. The elastic member 44 and the limiting member 42 are provided on the base 16. A plurality of limiting spaces 46 are provided on the inner side of the fixing portion 28. The plurality of limiting spaces 46 are arranged at intervals along the circumference of the fixing portion 28. During the rotation of the base 16, the limiting member 42 can selectively cooperate with one of the limiting spaces 46. By providing a plurality of limiting spaces 46 on the fixing portion 28, a limiting effect can be formed on the base 16, i.e., the support member 18, at a plurality of different positions.
[0046] Specifically, the number of the limiting spaces 46 is four, and the four limiting spaces 46 are evenly spaced along the circumference of the accessory body 12, and the central angles corresponding to any two adjacent limiting spaces 46 are 90°.
[0047] It is understandable that the specific number of the limiting member 42 and the elastic member 44 is not limited, and can be one, or a plurality of the same or different number as the limiting spaces 46. In the present embodiment, the number of the limiting member 42 and the elastic member 44 is one, and the limiting member 42 can cooperate with one of the plurality of limiting spaces 46 during the rotation process of the base 16.
[0048] In one embodiment, the size of the limiting space 46 gradually decreases from the opening 461 to the bottom 462 , that is, the limiting space 46 is largest at the opening 461 and smallest at the bottom 462 , so that when the limiting member 42 is inserted into the limiting space 46 , it can maintain a certain distance from the bottom 462 .
[0049] The direction from the opening 462 to the bottom 462 is the length direction of the limiting space 46 , and the size of the limiting space 46 gradually decreases, that is, along the length direction of the limiting space 46 , the width of the limiting space 46 gradually decreases.
[0050] The specific shape of the limiting space 46 is not limited, for example, semicircular, trapezoidal, etc., as long as the size gradually decreases from the opening 461 to the bottom 462.
[0051] It can be understood that the limiting space 46 may penetrate the fixing portion 28 in the radial direction, in which case the portion of the main body 26 close to and located outside the limiting space 46 constitutes the bottom 462, or the limiting space 46 may not penetrate the fixing portion 28, in which case the bottom 462 is located on the fixing portion 28. In this embodiment, the limiting space 46 does not penetrate the fixing portion 28 in the radial direction, forming a structure similar to a blind hole, and one end of the limiting member 42 is spaced a certain distance from the hole wall of the blind hole.
[0052] The limiting space 46 has a first inner wall 48 and second inner walls 50 located on opposite sides of the first inner wall 48, the first inner wall 48 is located at the bottom 462, the opening 461 is located between the ends of the two second inner walls 50 away from the first inner wall 48, the two second inner walls 50 extend in opposite directions from the first inner wall 48 to the opening 461, that is, the distance between the two second inner walls 50 gradually increases, the first inner wall 48 is spaced from the limiting member 42, and the second inner wall 50 is in contact with the limiting member 42. The direction perpendicular to the first inner wall 48 is the length direction of the limiting space 46, the vertical distance between the end of the second inner wall 50 away from the first inner wall 48 and the first inner wall 48 is the length of the limiting space 46, and the distance between the two second inner walls 50 in the direction perpendicular to the length direction, that is, the width direction, is the width of the limiting space 46. The limiting space 46 is roughly trapezoidal, and its first inner wall 48 does not contact the limiting member 42, thereby reducing the contact area between the limiting member 42 and the accessory body 12, thereby reducing wear.
[0053] In one embodiment, along the direction in which the limiting member 42 is inserted into the limiting space 46, that is, the direction from the opening 461 to the bottom 462, the size of the portion of the limiting member 42 located in the limiting space 46 gradually decreases. That is, the portion of the limiting member 42 located in the limiting space 46, the size of the portion close to the bottom 462 is the smallest, and the size of the portion far from the bottom 462 is the largest, so that the limiting member 42 can be inserted into the limiting space 46.
[0054] The direction in which the limit member 42 is inserted into the limit space 46 is the length direction of the limit member 42, and the size of the portion of the limit member 42 located in the limit space 46 gradually decreases, that is, along the length direction of the limit member 42, the width of the portion of the limit member 42 located in the limit space 46 gradually decreases.
[0055] It is understandable that the specific shape of the portion of the limiting member 42 located in the limiting space 46 is not limited, such as a semicircular shape, a trapezoidal shape, etc. In this embodiment, the portion of the limiting member 42 located in the limiting space 46 is substantially trapezoidal.
[0056] The stopper 42 has a first outer wall 52 and second outer walls 54 located on opposite sides of the first outer wall 52. The two second outer walls 54 extend in opposite directions away from the first outer wall 52, that is, in the direction away from the first outer wall 52, the distance between the two second outer walls 54 becomes larger and larger. The first outer wall 52 is spaced apart from the bottom 462 of the stopper space 46, and the second outer wall 54 abuts against the inner surface of the stopper space 46. The direction perpendicular to the first outer wall 52 is the length direction of the stopper 42. In the direction perpendicular to the length direction, that is, the width direction, the distance between the two second outer walls 54 is the width of the portion of the stopper 42 inserted into the stopper space 46. The first outer wall 52 of the stopper 42 does not contact the corresponding inner surface of the stopper space 46, thereby reducing the contact area between the stopper 42 and the accessory body 12, thereby reducing the wear of the stopper 42.
[0057] In this embodiment, the end of the limiting member 42 away from the elastic member 44, i.e., the portion inserted into the limiting space 46, and the limiting space 46 have substantially the same shape, both of which are trapezoidal. The first outer wall 52 of the limiting member 42 and the first inner wall 48 of the limiting space 46 are spaced apart, and the two second outer walls 54 of the limiting member 42 are respectively released from the two second inner walls 50 of the limiting space 46. Therefore, when the limiting member 42 withdraws from the limiting space 46, the second outer wall 54 of the limiting member 42 generates friction with the accessory body 12, while the first outer wall 52 does not generate friction with the accessory body 12, thereby reducing wear.
[0058] The first inner wall 48 and / or the second inner wall 50 are planes, and the first outer wall 52 and / or the second outer wall 54 are planes. Specifically, the first inner wall 48, the second inner wall 50, the first outer wall 52 and the second outer wall 54 are all planes, the first inner wall 48 and the first outer wall 52 are spaced and parallel, and the second inner wall 50 and the second outer wall 54 are in contact. Compared with a curved surface, a plane has a smaller surface area, which is conducive to further reducing the contact area between the stopper 42 and the accessory body 12, and can also reduce the difficulty of production.
[0059] Preferably, the connection between the first outer wall 52 and the two second outer walls 54 is an arc transition, that is, the first outer wall 52 and the second outer wall 54 are arc surfaces at the junction, so that the limiting member 42 can withdraw from the limiting space 46 more smoothly.
[0060] The contact portion between the stopper 42 and the elastic member 44 is a plane, which reduces the risk of the elastic member 44 breaking due to uneven force generated by the skewed contact surface. Specifically, the side surface of the stopper 42 close to the elastic member 44 is a plane as a whole.
[0061] In one embodiment, a receiving space 56 is provided on the base 16, and the limiting member 42 and the elastic member 44 are received in the receiving space 56, and the limiting member 42 can move in the receiving space 56. When the elastic member 44 is subjected to pressure or the pressure disappears, the limiting member 42 will slide in the receiving space 56 under the action of the elastic member 44, so that the limiting member 42 can be withdrawn from the limiting space 46 or inserted into the limiting space 46.
[0062] In other embodiments, when the limiting member 42 and the elastic member 44 are disposed on the accessory body 12 , the storage space 56 is disposed on the base 16 .
[0063] The limiting member 42 includes a sliding portion 58 and a protruding portion 60 located on one side of the sliding portion 58. The sliding portion 58 is movably arranged in the storage space 56, and the protruding portion 60 extends out of the storage space 56. The first outer wall 52 is located on the side of the protruding portion 60 away from the sliding portion 58. The second outer wall 54 is respectively located on the opposite sides of the protruding portion 60 and between the first outer wall 52 and the sliding portion 58. The side of the sliding portion 58 close to the protruding portion 60 is spaced from the inner surface opposite to the storage space 56, and the elastic member 44 is located on the side of the sliding portion 58 away from the protruding portion 60. By setting the limiting member including a sliding portion 58 and a protruding portion 60, the whole is roughly in an inverted L shape, and the sliding portion 58 is received in the receiving space 56 to form a certain limiting and guiding effect. Moreover, since the side of the sliding portion 58 away from the elastic member 44 is spaced from the inner surface opposite to the receiving space 56, when the limiting member 42 is worn to a certain extent, the limiting member 42 can move toward the bottom 462 of the limiting space 46 under the action of the elastic member 44, so that the second outer wall 54 of the limiting member 42 can still fit with the second inner wall 50 of the limiting space 46 to form a limiting effect and prevent shaking.
[0064] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
