Description

Technical Field

[0001] The present invention relates to the field of intelligent wearable electronic products, and more specifically, to a connector and a wearable device. Background Art

[0002] Intelligently fixing and removing objects is a consistent research direction. For example, existing connectors such as watch straps are all provided with positioning holes. When the watch strap is to be fixed, it needs to be manually placed in a position corresponding to the mounting hole of the positioning device, and the positioning rod is used to fix the watch strap. In the process of fixing and aiming the positioning hole of the watch strap and the mounting hole of the positioning device, the watch strap is prone to deviation, tilting or falling off, resulting in the inability to quickly and effectively fix the watch strap. In addition, when you want to remove the watch strap, you need to manually remove the positioning rod inserted in the positioning hole of the watch strap and the mounting hole of the positioning device. During the removal process, the positioning rod may get stuck in the positioning hole and the mounting hole, resulting in the inability to remove the watch strap from the positioning device. The existing positioning device makes the process of fixing and removing objects cumbersome and complicated, which is not conducive to improving the efficiency of the operator.

DETAILED DESCRIPTION

[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] According to one embodiment of the present disclosure, a connecting member is provided. Figure 1 As shown, the connecting piece includes: a connecting piece body 3.

[0043] Two lugs 4 are provided on the connector body 3. The two lugs 4 are spaced apart. An accommodating cavity is provided in the lug 4. A first through hole 401 is provided on the lug 4. The first through holes 401 of the two lugs 4 are arranged opposite to each other. A movable element 5 is provided in the accommodating cavity. The movable element 5 can switch between a first deformation and a second deformation in the accommodating cavity. A push rod 504 is provided on one side of the movable element 5 close to the first through hole 401. One of the two push rods is a first push rod 504a, and the other is a second push rod 504b.

[0044] When the two movable elements 5 are in the first deformation, the end of the first push rod 504a extends out of the corresponding first through hole 401 , and the end of the second push rod 504b retracts into the corresponding first through hole 401 .

[0045] When the two movable elements 5 are in the second deformation, the ends of the first push rods 504 a are retracted into the corresponding first through holes 401 , and the ends of the second push rods 504 b are extended out of the corresponding first through holes 401 .

[0046] like Figure 7 As shown, two lugs 4 are provided on the connector body 3. The two lugs 4 are spaced apart from each other. An accommodating cavity is provided in the lug 4, and a movable element 5 is provided in the accommodating cavity. A first through hole 401 is provided on both lugs 4, and the first through holes 401 of the two lugs 4 are arranged opposite to each other.

[0047] It should be noted that the two lugs 4 can be set on the connector body 3. Of course, they can also be fixed at other suitable positions, such as a desktop, wall, etc. As long as the two lugs 4 can be fixed, there is no limitation here, and technicians in this field can make a choice according to actual needs.

[0048] like Figure 5 and Figure 6 As shown, a push rod is provided on the side of the movable element 5 close to the first through hole 401. One of the two push rods is a first push rod 504a, and the other is a second push rod 504b. The first push rod 504a and the second push rod 504b are used to extend and retract into the corresponding first through hole 401, thereby achieving the purpose of fixing and releasing.

[0049] The movable element 5 can switch between a first deformation and a second deformation in the accommodating cavity.

[0050] For example, Fig. 9 As shown, the connector body 3 achieves the purpose of fixation, and the two movable elements 5 are in the first deformation. Under the first deformation, the deformation directions of the two movable elements 5 are consistent, and both move toward the side of the lug where the second push rod 504b is located to achieve the purpose of fixation. The end of the first push rod 504a extends out of the corresponding first through hole 401. The end of the second push rod 504b retracts into the corresponding first through hole 401. By controlling the first push rod 504a to extend out of the first through hole 401 and the second push rod 504b to retract into the first through hole 401, the two movable elements 5 are in the first deformation, thereby achieving the purpose of fixation. The entire fixing process is simple and quick, avoiding tedious manual aiming, allowing the operator to easily achieve the purpose of fixation, which is conducive to improving operating efficiency.

[0051] like Figure 8As shown, the connecting member body 3 achieves the purpose of release, and the two movable elements 5 are in the second deformation. Under the second deformation, the deformation directions of the two movable elements 5 are consistent, and both move toward the side of the lug where the first push rod 504a is located to achieve the purpose of release. The end of the first push rod 504a is retracted into the corresponding first through hole 401. The second push rod 504b extends out of the corresponding first through hole 401. The end of the first push rod 504a and the end of the second push rod 504b are flush with the outer surface of the lug 4 where they are located. By controlling the first push rod 504a to retract into the first through hole 401 and the second push rod 504b to extend out of the first through hole 401, the two movable elements 5 are in the second deformation, thereby achieving the purpose of release. The entire fixing process is simple and quick, avoiding tedious manual aiming, allowing the operator to easily achieve the purpose of release, which is conducive to improving operating efficiency.

[0052] In one example, the movable element 5 can maintain the first deformation and the second deformation in the accommodating cavity.

[0053] For example, the movable element 5 can maintain the first deformation, so that the connector body 3 can effectively achieve the purpose of fixing. The movable element 5 can maintain the second deformation, so that the connector body 3 can effectively achieve the purpose of releasing. In addition, keeping the two movable elements 5 in the second deformation (i.e., the initial state without deformation, the idle state without fixing any object) facilitates the fixing of the object next time, avoids the process of resetting the connector body 3, and is conducive to improving the operation efficiency.

[0054] In one example, the movable element 5 is an arc-shaped spring.

[0055] For example, the movable element 5 is an arc-shaped spring. The arc-shaped spring is usually in a semi-arc shape. It should be noted that if the arc-shaped spring is stretched so that the spring is in a plane shape, the width of the spring is larger than the width of the accommodating cavity provided in the lug 4. Then, when the spring is placed in the accommodating cavity, the static state of the spring is generally to bulge to any side of the accommodating cavity, thereby maintaining the movable element 5 in the first deformation or the second deformation, and finally achieving effective fixation and release of the object. In addition, the arc-shaped spring has a simple structure and low cost, which reduces the manufacturing cost and assembly process flow, and also improves the operating efficiency of the operator.

[0056] In an example, Figure 3 and Figure 4 As shown, the movable element 5 includes a first sub-piece 501, a second sub-piece 502 and a third sub-piece 503 which are elastically connected together. The second sub-piece 502 is located between the first sub-piece 501 and the third sub-piece 503. The first sub-piece 501 and the third sub-piece 503 are bent toward the same side of the second sub-piece 502. The top rod 504 is connected to the second sub-piece 502.

[0057] For example, the first sub-piece 501 and the second sub-piece 502 can be fixed inside the accommodating chamber, and a push rod is connected to the third sub-piece 503 arranged between the first sub-piece 501 and the second sub-piece 502. That is, the first sub-piece 501, the second sub-piece 502, the third sub-piece 503 and the push rod together constitute the movable element 5. Since the first sub-piece 501, the second sub-piece 502 and the third sub-piece 503 are elastically connected, and the first sub-piece 501 and the third sub-piece 503 are all fixed on the accommodating chamber, the second sub-piece 502 can move relative to the inside of the accommodating chamber, and since the second sub-piece 502 is provided with a push rod, the second sub-piece 502 can drive the push rod to pass through the first through hole 401 and move in the accommodating chamber. The interconnected sub-pieces and the push rod constitute the movable element 5, so that the operation of the movable element 5 is simple and convenient, which is conducive to improving the operating efficiency.

[0058] In one example, both ends of the movable element 5 are fixed in the accommodating cavity.

[0059] For example, both ends of the movable element 5 are fixed inside the accommodating cavity, so that the movable element 5 can move relative to the inside of the accommodating cavity, thereby achieving the fixation and release of the object, which is beneficial to improving the operation efficiency.

[0060] In one example, the lug 4 is a rectangular parallelepiped structure, and a first opening 402 is disposed on a surface opposite to the surface where the first through hole 401 is located.

[0061] For example, the first opening 402 is used by an operator to control the movable element 5 disposed in the lug 4 to extend or retract into the first through hole 401 , thereby achieving the purpose of fixing and releasing the object.

[0062] It should be noted that the lug 4 may also be of other suitable shapes, as long as a receiving cavity is provided inside the lug 4 and can accommodate the movable element 5, and a first through hole 401 is provided on the lug 4. The shape of the lug 4 is not limited here, and technicians in this field can choose according to actual needs.

[0063] In one example, a second opening 403 is provided on the side of the lug 4 , and a cover plate 6 is fixedly provided on the second opening 403 .

[0064] For example, the second opening 403 can be provided to facilitate the placement of the movable element 5 in the accommodating cavity, which is convenient for the assembly of the connector body 3. The cover plate 6 is provided on the second opening 403 to prevent foreign matter from entering the accommodating cavity through the second opening 403, thereby preventing the foreign matter from affecting the normal operation of the movable element 5 and improving the effectiveness of the operation of the movable element 5.

[0065] In one example, a soft rubber layer 7 is disposed outside the lug 4 .

[0066] For example, a soft rubber layer 7 is provided on the outer side of the lug 4. This can prevent foreign matter from entering the accommodating cavity, and prevent the foreign matter from affecting the normal operation of the movable element 5. In addition, the soft rubber layer 7 itself is elastic, and the operator can directly press the relative position of the soft rubber layer 7 and the movable element 5 to control the movable element 5 to switch between the first deformation and the second deformation. The provision of the soft rubber layer 7 can improve the comfort of operation, and the soft rubber layer 7 can reset itself by using its own elasticity, so that the connector body 3 has a beautiful appearance.

[0067] In one example, the push rod includes a rod portion 5041 and a head portion 5042. The rod portion 5041 is connected to the head portion 5042. The head portion 5042 is connected to the movable element 5. The head portion 5042 is located in the accommodating cavity. The radial dimension of the rod portion 5041 is less than or equal to the radial dimension of the first through hole 401. The radial dimension of the head portion 5042 is greater than the radial dimension of the second through hole 401.

[0068] For example, the head 5042 of the push rod 504 is connected to the movable element 5, and the head 5042 is located in the accommodating cavity, and the radial dimension of the head 5042 is greater than the radial dimension of the first through hole 401. The rod 5041 is connected to the head 5042, and the rod 5041 can be retracted into or extended out of the first through hole 401, and the radial dimension of the rod 5041 is less than or equal to the radial dimension of the first through hole 401.

[0069] Since the radial dimension of the rod 5041 is less than or equal to the radial dimension of the first through hole 401, the movable element 5 can drive the rod 5041 to move in the first through hole 401, thereby realizing the switching of the movable element 5 between the first deformation and the second deformation. Since the radial dimension of the head 5042 is greater than the radial dimension of the first through hole 401, the head 5042 can ensure that the rod 5041 will not completely escape from the accommodating cavity, thereby maintaining an effective connection between the rod 5041 and the movable element 5, and finally realizing the effective switching of the movable element 5 between the first deformation and the second deformation.

[0070] In one example, the two accommodating cavities have the same size in the sliding direction. The length of the first push rod 504a is greater than the length of the second push rod 504b.

[0071] For example, the two accommodating cavities have the same size in the sliding direction. The length of the first push rod 504a is greater than the length of the second push rod 504b. In this way, at least a portion of the first push rod 504a can be inserted into the object itself, thereby effectively fixing the object; when release is required, the second push rod 504b can extend out of the first through hole and push out at least a portion of the first push rod 504a that is inserted into the object itself, thereby releasing the object.

[0072] It should be noted that the sizes of the two accommodating cavities in the sliding direction may be unequal, and the length of the first push rod 504a and the length of the second push rod 504b may be equal, which can also achieve the above-mentioned fixing and releasing purposes. No limitation is made here, and technicians in this field can select and set it according to actual needs.

[0073] According to another embodiment of the present disclosure, a wearable device is provided. The wearable device includes a device body, a connecting strap 1 and a positioning rod 2. The connecting strap 1 is provided with a second through hole 101. The positioning rod 2 is slidably disposed in the second through hole 101. The connecting strap 1 is fixed to the above-mentioned connecting member through the positioning rod 2.

[0074] For example, the wearable device may be a watch, a bracelet, a VR headset, etc., which is not limited here, and technicians in this field can choose according to actual needs.

[0075] The connecting strap 1 can be a strap of a watch or a bracelet, or a strap of a VR headset, etc., and is not limited here. Those skilled in the art can choose according to actual needs.

[0076] like Figure 1 and Figure 2 As shown, a second through hole 101 is provided on the connecting strap 1. A positioning rod 2 is provided in the through hole. The positioning rod 2 is slidably provided in the second through hole 101. The positioning rod 2 is used to cooperate with the movable element 5 provided on the connecting member body 3 to achieve the fixing and releasing of the connecting strap 1 together.

[0077] In one example, the connecting strap 1 is located between two lugs 4 .

[0078] When the two movable elements 5 are in the first deformation, the end of the first push rod 504a extends out of the corresponding first through hole 401 and extends into the second through hole 101. The end of the first push rod 504a abuts against one end of the positioning rod 2. The other end of the positioning rod 2 abuts against the end of the second push rod 504b. And the end of the second push rod 504b retracts into the corresponding first through hole 401.

[0079] When the two movable elements are in the second deformation, the end of the second push rod 504b extends out of the corresponding first through hole 401. The end of the second push rod 504b abuts against the other end of the positioning rod 2 and is flush with the outer surface of the lug where the second push rod 504b is located. The end of the first push rod 504a retracts into the corresponding first through hole 401.

[0080] When the connecting strap 1 is placed between the two lugs 4, the first through hole 101 and the two second through holes 401 are on the same horizontal line, and then the two oppositely arranged movable elements 5 can be used to push the positioning rod 2 in the second through hole 101 to achieve the fixing and release of the connecting strap 1. Two movable elements 5 are arranged inside the two oppositely arranged lugs 4, and the movable elements 5 can extend and retract into the first through hole 401, and then can easily switch between the first deformation and the second deformation, and conveniently and quickly realize the pushing of the positioning rod 2, avoiding the complicated aiming and fixing process between the connecting strap 1 and the connecting member body 3, and improving the operating efficiency of the operator.

[0081] It should be noted that the length of the positioning rod 2 is equal to the length of the first through hole 101 . Usually, when the positioning rod 2 is inserted into the first through hole 101 , both ends of the positioning rod 2 are flush with both ends of the first through hole 101 .

[0082] In one example, a damping member 8 is disposed on the outer sleeve of the positioning rod 2 .

[0083] For example, a damping member 8 is provided on the outer sleeve of the positioning rod 2, so that when the positioning rod 2 is inserted into the second through hole 101, it can be stably set inside the second through hole 101 and will not slip out of the second through hole 101, making it easy to operate the subsequent fixing and releasing of the connecting strap 1, thereby improving the operating efficiency.

[0084] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0085] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
