Detailed ways

In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

In traditional watch bands, a linear dial structure in which a spring is matched with a barrel needle is usually used to enable the watch band to snap into or separate from the watch case. Specifically, in the process of separating the watchband from the watch case, the user needs to move the tube needle so that the tube needle can contract inside the watchband, thereby detaching from the fixing hole of the watch case to release the gap between the watchband and the watch case. Connect, and then separate the strap; in the process of snapping the strap into the case, the user also needs to move the tube needle so that the tube needle can shrink into the strap, thereby reducing the width of the strap to place the strap Between the fixing holes of the watch case, the tube needle is then released, and the tube needle is pushed out of the watch band by the spring and snaps into the fixing hole of the watch case, thereby fixing the watch band in the watch case. However, in this structure, due to the relatively small structure of the barrel needle, the barrel needle will exert a greater pressure on the fingers when the user compresses the barrel needle, which may cause discomfort to the fingers and may damage the skin in severe cases.

In order to solve the problem of discomfort or damage to the skin caused by large pressure on the fingers when the watchband is separated from the watchcase or installed on the watchcase, this application provides a watchband and a watch.

Referring to FIG. 1 first, the watchband 10 includes a housing 110 in which a rotating part (refer to 1321 in FIGS. 1 and 2) and a clamping part (refer to 113 and 122 in FIG. 1) are provided. The watch case is generally provided with opposite fixing holes so that the clamping parts on the watch band can be clamped into the fixing holes, so that the watch band is installed and connected to the watch case. Rotating the rotating component can drive the clamping component to expand and contract relative to the housing 110. For example, by rotating the rotating part, the clamping part can protrude from the housing 110 and can be clamped into the fixing hole of the watch case, so as to install the watch band 10 on the watch case. When the watchband 10 needs to be detached from the watch case, the user can rotate the rotating part to drive the clamping part to shrink into the housing 110 to escape the fixing hole of the watch case, and release the clamping between the clamping part and the watch case In addition, the width of the watchband 10 can be reduced after the clamping parts are contracted, which facilitates the separation of the watchband 10 from the watch case. That is, the present application can drive the clamping part of the watchband to expand and contract with respect to the watchband by rotating the rotating part of the watchband, so that the clamping part can be locked into or detached from the watchcase to realize the installation and removal of the watchband. The above-mentioned watch case can be a mechanical watch case or an electronic watch case. In addition to matching with the watch case, the watch band 10 can also be used as a winding part of other wearable devices, such as arms, heads, legs, etc. . Specifically, the watch band 10 in some embodiments has a rectangular structure.

Referring specifically to FIG. 2, in some embodiments, the watchband 10 includes a housing 110, a first telescopic member 120 (clamping member), and a rotating member 130 (rotating member). The housing 110 is provided with a cavity 111. The rotating member 130 is disposed in the cavity 111 and can rotate in the cavity 111. The first telescopic member 120 includes a first transmission portion 121 and a first clamping portion 122. The first transmission portion 121 is arranged in the cavity 111 and connected to the rotating member 130. One end of the first clamping portion 122 is connected to the first transmission portion 121, and the other end extends out of the housing 110. The first clamping portion 122 is opposite to the first transmission portion 121 fixed. When the rotating member 130 rotates, it can act on the first transmission portion 121 to drive the other end of the first clamping portion 122 to expand and contract in the direction extending out of the housing 110. The extension or contraction movement is determined by the rotation direction of the rotating member 130. Specifically, the housing 110 in some embodiments has a rectangular structure and is made of metal.

It should be noted that, in some embodiments, the structure for connecting one end of the watchband 10 to the watch case is the housing 110. In these embodiments, not the entire outer structure of the watchband 10 is the housing 110.

Wherein, the housing 110 is provided with a first through hole 1122 in the width direction (ie, the width direction of the watch band 10), and the first through hole 1122 communicates with the cavity 111 and the outside. The first clamping portion 122 passes through the first through hole 1122 so that one end extends out of the housing 110. The first clamping portion 122 has a cylindrical structure with a circular, elliptical, triangular, or polygonal cross section. The shape and size of the first through hole 1122 are matched with the first clamping portion 122, so that the first through hole 1122 can effectively guide the first clamping portion 122 to limit the expansion and contraction direction of the first clamping portion 122.

The first transmission part 121 includes a first rack 1211, and the rotating member 130 includes a main gear 131. The main gear 131 can rotate on a fixed axis in the housing 110 and mesh with the first rack 1211, so that the main gear 131 will The first rack 1211 is driven to move, and the first clamping portion 122 is driven to expand and contract with respect to the housing 110. The main gear 131 can be provided with a slot in the axial direction, and the housing 110 is provided with a jack 115 corresponding to the slot (refer to FIG. 1). The user can extend a handle adapted to the shape of the slot into the jack 115 and The main gear 131 can be controlled to rotate by turning the handle at this time. In other embodiments, a knob may be fixedly arranged in the axial direction of the main gear 131, and the housing 110 is provided with a socket 115 corresponding to the knob, and the knob on the main gear 131 extends out of the socket 115 of the housing 110 , The user can manipulate the main gear 131 to rotate by rotating the knob. The knob in the above embodiment is fixedly connected to the main gear 131.

Continuing to refer to FIG. 2, the first telescopic member 120 further includes a first limiting unit 123, and the first limiting unit 123 is connected between the first transmission portion 121 and the first clamping portion 122. The first limiting unit 123 moves synchronously with the first transmission part 121 and the first clamping part 122. On the side wall of the housing 110 where the first through hole 1122 is opened, the projected area of the first limiting unit 123 on the side wall is larger than the area of the first through hole 1122, thereby protruding from the first clamping portion 122 After the housing 110, the first limiting unit 123 can abut against the side wall of the housing 110 where the first through hole 1122 is opened in the extending direction of the first through hole 1122 without entering the first through hole 1122. In this way, the first clamping portion 122 is prevented from continuing to extend, and the extending distance of the first clamping portion 122 is limited. In some embodiments, the first limiting unit 123 has a rectangular structure.

In addition, a first return member 140 is disposed in the cavity 111, and the first return member 140 can apply a force to the first telescopic member 120 to drive the first clamping portion 122 to extend out of the housing 110. The first return member 140 may be an elastic element. One end of the elastic element is connected to the first telescopic element 120, and the other end is relatively fixed to the housing 110. The elastic element can directly or indirectly apply an elastic force to the first clamping portion 122 to drive The first clamping portion 122 extends out of the housing 110. In some embodiments, the elastic element may be an elastic spring, an elastic piece or an elastic silicone piece.

In the embodiment shown in FIG. 2, the first return member 140 is a telescopic spring, a spring fixing block 141 is provided in the cavity 111, and the spring fixing block 141 is relatively fixed to the housing 110. One end of the first return member 140 It is fixed on the spring fixing block 141, and the other end is connected to a side of the first limiting unit 123 away from the first clamping portion 122. When the main gear 131 is rotated to shrink the first clamping portion 122 into the cavity 111, the elastic element is compressed. When the main gear 131 is released, the elastic element will release the elastic force to act on the first limiting unit 123, thereby The first clamping portion 122 is driven to extend out of the housing 110.

1 again, in the embodiment of FIG. 1, in order to allow the watch band to be clamped in the opposite fixing holes on the watch case, the outer wall of the housing 110 is also provided with a retaining block 113, a retaining block 113 One end extending from the housing 110 with the first clamping portion 122 is respectively located at two opposite sides of the housing 110. In some embodiments, the locking block 113 is located on the axial extension line of the first locking portion 122. When the user needs to install and connect the watch band 10 to the watch case, the locking block 113 can be inserted into a fixing hole of the watch case first, and then the rotating member 130 can be operated to shrink the first clamping part 122 into the case 110 Then, the first through hole 1122 of the housing 110 is close to the fixing hole of the watch case. At this time, one end of the first clamping portion 122 will be ejected from the housing 110 under the action of the first return member 140, and be locked into the watch case. In the other fixing hole of the shell. Therefore, the transmission structure can be provided on only one side of the housing 110, thereby simplifying the structure of the watch band and reducing the cost and difficulty of operation. In the above-mentioned embodiment, the end of the first clamping portion 122 away from the first transmission portion 121 can be retracted to enter and exit the side of the housing 110, and the other side of the housing 110 is fixedly provided with a clamping block 113 for clamping The bit block 113 is used to snap into the watch case.

By adopting the above-mentioned rotational drive method instead of the general linear compression method, the user can effectively reduce the pressure on the finger during operation when installing or removing the watchband, thereby reducing the possibility of finger injury. In addition, by arranging the transmission mechanism on the watchband, the structural requirements for the watchcase during the clamping process can be reduced, and it can effectively prevent the appearance of the watchcase from being damaged by the additional fitting structure provided on the watchcase in order to cooperate with the watchband , And avoid damaging the integrity of the case and the curved structure of the case.

Referring to FIG. 2, in some embodiments, the rotating member 30 further includes a secondary gear 132, which can rotate on a fixed axis in the cavity 111 and mesh with the primary gear 131. In some embodiments, a slot 1321 is opened in the axial direction of the pin gear 132, and the housing 110 has a socket 115 corresponding to the slot 1321 (refer to FIG. 1). The user can set the handle (refer to the handle 13 in FIG. 4). ) Extends into the socket 115 and snaps into the slot 1321, at this time, turning the handle can control the auxiliary gear 132, thereby driving the main gear 131 to rotate. In some embodiments, the shape of the slot in the main gear 131 or the auxiliary gear 132 may be an oval, triangle, polygon, or a cross-sectional shape similar to a key, and the shape of the handle matches the shape of the slot, so that When the main gear 131 or the auxiliary gear 132 is turned by the handle, it is not easy to slip.

In other embodiments, a knob can also be fixedly arranged in the axial direction of the auxiliary gear 132, and the housing 110 is provided with a socket 115 corresponding to the knob, and the knob on the auxiliary gear 132 extends out of the socket 115. The auxiliary gear 132 can be manipulated by rotating the knob. 3, in some embodiments, the cavity 111 is also provided with a gear fixing column 114, the gear fixing column 114 is fixedly connected to the housing 110, the main gear 131 is provided with a fixed shaft groove in the axial direction, and the gear fixing column 114 can The main gear 131 is locked into the fixed shaft groove of the main gear 131 so that the main gear 131 can rotate about the fixed shaft of the gear fixing column 114.

It should be noted that, in some embodiments, when the rotating member 130 is described as being disposed in the cavity 111, part of the structure on the rotating member 130 can also extend out of the housing 110.

In addition, referring to FIGS. 1 and 2, in some embodiments, there is a distance between the pinion gear 132 (the center of the slot 1321) and the axial extension line of the first clamping portion 122. In some embodiments, the separation distance is greater than or equal to the radius of the pin gear 132. For example, the watch band 10 includes a casing 110 and a band 190. One end of the band 190 is connected to one end of the casing 110. The band 190 is used to wrap the wrist and other parts. The casing is provided with a clamping part to connect the watch case. Wherein, the locking block 113 is arranged on the axial extension line of the first clamping portion 122, and the axial extension line of the first clamping portion 122 passes through the main gear 131, and the auxiliary gear 132 meshes with the main gear 131 closest to the belt Therefore, there is a separation distance from the center of the slot 1321 on the secondary gear 132 to the axial extension line of the first clamping portion 122, and the separation distance is greater than or equal to the radius of the secondary gear 132, that is, the secondary gear 132 should As far as possible from the axial extension line of the first rack 122. At this time, when the watch case is provided with a groove, the groove is provided with a fixing hole, and the first clamping portion 122 of the watch band 10 is clamped into the fixing hole so that the watch band 10 is installed and connected to the watch case, the auxiliary gear 131 The slot 1321 in the middle can expose the groove of the watch case (that is, the slot 1321 will not be blocked by the groove structure of the watch case after the watch band 10 is connected to the watch case), so that the watch band 10 and the watch case will be separated later. The handle can be inserted into the slot 1321. This arrangement can prevent the slot 1321 from being blocked by the groove structure in the watch case, and prevent the hand from being unable to extend into the slot 1321 in the future. The radii of the main gear 131 and the auxiliary gear 132 can be understood as the addendum radius of the gear. In addition, when it is described that the auxiliary gear 132 is meshed with the side of the main gear 131 closest to the belt body 190, it can also be understood that the housing 110 includes an end surface 116 facing the case when the watch case is connected, and the auxiliary gear 132 is meshed with the main gear 131 The side away from the end surface 116.

In some embodiments, the number of teeth of the main gear 131 and the auxiliary gear 132 are the same. In other embodiments, the transmission ratio between the auxiliary gear 132 and the main gear 131 is increased, so that the auxiliary gear 132 can be rotated at a small angle to allow the first locking portion 122 to have a larger displacement, allowing the user to remove the watchband The operation is easier. Specifically, the number of teeth of the auxiliary gear 132 in some embodiments is greater than the number of teeth of the main gear 131. On the other hand, in some embodiments, the diameter of the addendum circle of the auxiliary gear 132 may be greater than the diameter of the addendum circle of the main gear 131.

For the first return member 140 as an elastic element, in other embodiments, one end of the first return member 140 and the first clamping portion 122 may be connected to the same side of the first limiting unit 123, and the first The other end of the return member 140 is connected to the cavity wall of the cavity 111. At this time, when the rotating member 130 is rotated to shrink the first clamping portion 122 into the housing 110, the first returning member 140 is stretched, and when the rotating member 130 is released, the first returning member 140 will release the elasticity The force is used to apply a pulling force to the first limiting unit 123 to drive the first clamping portion 122 to extend out of the housing 110.

In other embodiments, the first return member 140 may also be a magnetic element, the magnetic element is fixed relative to the housing 110, and the magnetic element can apply a magnetic force to the first telescopic element 120. Specifically, the magnetic element can apply a magnetic force to the first limiting unit 123 to drive the first clamping portion 122 to extend out of the housing 110. The first limiting unit 123 has magnetism. At this time, when the magnetic element is disposed on the side of the first limiting unit 123 away from the first clamping portion 122, the magnetic element can apply a repulsive force to the first limiting unit 123 When the magnetic element and the first clamping portion 122 are arranged on the same side of the first limiting unit 123, the magnetic element exerts an attractive force on the first limiting unit 123. In addition, when the magnetic element and the first clamping portion 122 are arranged on the same side of the first limiting unit 123, the first limiting unit 123 may not have magnetism, but the material of the first limiting unit 123 should be A material that is magnetically attracted (such as iron, cobalt, nickel, stainless steel, etc.), so that the magnetic element can also apply an attractive force to the first limiting unit 123, thereby providing the first clamping portion 122 with a force to extend the housing 110 . That is, the first return member 140 is a magnetic element, and the first return member 140 is fixed relative to the housing 110. The first return member 140 can apply a magnetic force to the first telescopic member 120 to drive the first clamping portion 122 away from the One end of a transmission part 121 is away from the housing 110.

It should be noted that the first return member 140 may not be provided in the watchband 10, but the end of the first clamping portion 122 protruding from the housing 110 is magnetic. At this time, the first clamping portion 122 extends The magnetic effect of the output end and the fixing hole in the watch case drives the protruding end of the first clamping portion 122 to snap into the fixing hole under the action of magnetic attraction when it is close to the fixing hole of the watch case. That is, the end of the first clamping portion 122 away from the first transmission portion 121 is magnetic.

In some embodiments, the first return member 140 and the end of the first clamping portion 122 may not be provided with magnetism. Instead, a torsion spring is provided in the cavity 111, and one end of the torsion spring is opposite to the housing 110. Fixed, the other end of the torsion spring is connected to the main gear 131. When the main gear 131 is rotated to shrink the first clamping portion 122 into the housing 110, the torsion spring provides a torsion force to the main gear 131 so that the main gear can be reset (reversely rotated) after being rotated, and drives the first rack 1211 moves, thereby driving the first clamping portion 122 to extend out of the housing 110. That is, when the rotating member 130 is rotated and released, the rotating member 130 will reversely rotate under the action of the torsion spring and drive the first rack 1211 to move, thereby driving the first clamping portion 122 to extend out of the housing 110 again.

Referring to Figures 2, 3, and 4, in other embodiments, the retaining block may not be provided on the outer wall of the housing 110, but a transmission member (first telescopic member 120) may be provided on opposite sides of the housing 110.

The second clamping portion 162 has a cylindrical structure whose cross-section may be a circle, an ellipse, a triangle, or a polygon. In some embodiments, the shape and size of the second through hole 1124 match the second clamping portion 162, so that the second through hole 1124 can guide the second clamping portion 162 to define the second clamping portion 162 Extension direction. The structure and relationship between the first through hole 1122 and the first clamping portion 122 can refer to the above-mentioned embodiment. In some embodiments, the extension directions of the first clamping portion 122 and the second clamping portion 162 are on the same straight line.

In the radial extension direction of the main gear 131, the first rack 1211 and the second rack 1611 are respectively meshed on opposite sides of the main gear 131. That is, the first rack 1211 and the second rack 1611 mesh with the main gear 131 on opposite sides of the main gear 131 respectively. At this time, the rotation of the main gear 131 can drive the first rack 1211 and the second rack 1611 to move in opposite directions, thereby driving one end of the first clamping portion 122 and one end of the second clamping portion 162 toward the housing 110. The housing 110 is internally contracted or extended. The extension or contraction movement of the first clamping portion 122 and the second clamping portion 162 is determined by the rotation direction of the main gear 131.
