A wrist-worn device

Abstract

The present invention discloses a wrist-worn device, comprising a watch case and a watch strap, wherein grooves are respectively provided at both ends of the watch case. The wrist-worn device further comprises: a connector connected to the watch strap and disposed in the groove; a watch strap pressure piece having a push-pull portion and slidably disposed on the watch case in a first direction to extend into or out of the groove, wherein the first direction is a direction perpendicular to the side of the watch strap; and an elastic piece connected between the watch strap pressure piece and the watch case. When the push-pull portion is not subjected to an external force, the elastic force of the elastic piece causes the watch strap pressure piece to press the connector tightly. When the push-pull portion is subjected to an external force, causing the watch strap pressure piece to compress the elastic piece, the watch strap pressure piece releases the connector. The wrist-worn device utilizes the watch strap pressure piece to compress the connector under the elastic force of the elastic piece to achieve fixation between the watch strap and the watch case. When the watch strap is installed or removed, external force is only applied to the push-pull portion in the first direction, causing the watch strap pressure piece to compress the elastic piece, thereby achieving installation and removal of the watch strap. It can be seen that the watch strap of the wrist-worn device is easy to install and remove, and convenient for replacing the watch strap.

Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and more particularly to a wrist-worn device. Background Art

[0002] In the prior art, wrist-worn devices, such as watches or bracelets, generally use a pin to connect the watch case and the watch strap. This connection method makes it difficult to remove the pin, which makes it difficult to replace the watch strap.

[0003] Therefore, how to provide a wrist-worn device with convenient strap removal is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a wrist-worn device whose strap is convenient for assembly and disassembly.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A wrist-worn device, comprising a watch case and a watch strap, wherein both ends of the watch case are respectively provided with grooves, and the wrist-worn device further comprises:

[0007] a connecting piece connected to the watchband and disposed in the groove;

[0008] a watchband pressing piece, provided with a push-pull portion, and slidably disposed on the watch case along a first direction to extend into or out of the groove, wherein the first direction is a direction perpendicular to the side of the watchband;

[0009] An elastic member is connected between the strap pressure member and the watch case. When the push-pull portion is not subjected to external force, the elastic force of the elastic member causes the strap pressure member to press the connecting member. When the push-pull portion is subjected to external force, causing the strap pressure member to compress the elastic member, the strap pressure member releases the connecting member.

[0010] Optionally, the watch case is provided with a dovetail groove, and the watch strap pressing piece is provided with a first boss that slides in cooperation with the dovetail groove.

[0011] Optionally, the watch case is provided with a first buckle, and the watch strap pressure piece is provided with a second buckle for cooperating with the first buckle to limit the position, so as to prevent the watch strap pressure piece from separating from the watch case along the first direction.

[0012] Optionally, the push-pull portion is a raised portion provided on the top of the strap pressure piece.

[0013] Optionally, the watch case is provided with a first limiting groove for accommodating the elastic member.

[0014] Optionally, the connecting member includes an embedded portion, and the embedded portion is embedded in the watch strap.

[0015] Optionally, a second boss is provided at the bottom of the connecting member, and the watch case is provided with a second limiting groove for cooperating with the second boss to limit the position.

[0016] Optionally, a limiting step is provided on the top of the connecting member, and the strap pressing member is provided with a third boss for cooperating with the limiting step for limiting position.

[0017] Optionally, watch lugs are respectively provided at both ends of the watch case, the watch lugs are arranged at an angle, the grooves are arranged on the watch lugs, the grooves include a clamping groove portion for setting the connecting piece and a supporting groove portion for supporting the watch strap, and the supporting groove portion extends from the clamping groove portion toward the length direction of the watch strap.

[0018] Optionally, the number of the strap pressure piece and the elastic piece corresponding to a single groove is two respectively, and the single strap pressure piece and the single elastic piece form an elastic component, and the two elastic components corresponding to the single groove are arranged relative to each other to utilize the two strap pressure pieces to clamp the connecting piece.

[0019] In the wrist-worn device provided by the present invention, in normal use, the band pressure piece, under the elastic force of the elastic piece, compresses the connector, thereby securing the connector to the watch case, that is, securing the band to the watch case. When the band needs to be removed, an external force is applied to the push-pull portion in a first direction, causing the band pressure piece to compress the elastic piece, thereby compressing the elastic piece. At this time, the band pressure piece releases the connector, thereby allowing the band and the connector to be removed from the groove of the watch case, thereby achieving removal of the band. When the band and the watch case are assembled, an external force is applied to the push-pull portion in a first direction, causing the band pressure piece to compress the elastic piece, thereby compressing the elastic piece. At this time, the band pressure piece withdraws from the groove to make way for the connector, thereby allowing the connector to be placed into the groove of the watch case. The push-pull portion is then released, allowing the band pressure piece to return to its original position under the elastic force of the elastic piece, thereby compressing the connector, thereby achieving assembly of the band and the watch case.

[0020] It can be seen from this that this embodiment uses the strap pressure piece to compress the connecting piece under the elastic force of the elastic piece to achieve the fixation of the strap and the watch case. When removing the strap, it is only necessary to apply external force to the push-pull part along the first direction to make the strap pressure piece compress the elastic piece to achieve the installation and removal of the strap. It can be seen that the strap of the wrist-worn device is easy to assemble and disassemble, and it is convenient to replace the strap; in addition, the strap is fixed by clamping the connecting piece. On the one hand, the reliability of the strap fixation can be ensured by improving the structural strength of the connecting piece. On the other hand, the clamping method is not easy to damage the connecting piece and the strap; furthermore, the prior art uses a quick release button to achieve the removal of the strap by relying on the elastic deformation of the parts. This removal method is prone to damage to the parts over time and has poor durability. The present application adopts the above method to achieve the fixation of the strap, which can avoid the deformation of the strap after long-term use, etc., and has good durability and long service life.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The core of the present invention is to provide a wrist-worn device whose strap is easy to assemble and disassemble.

[0035] Please refer to Figure 1 An embodiment of the present invention provides a wrist-worn device, including a watch case 1, a watch strap 2, a connector 3, a watch strap pressure piece 4 and an elastic piece 5, wherein grooves 111 are respectively provided at both ends of the watch case 1; the connector 3 is connected to the watch strap 2, and the connector 3 is arranged in the groove 111; the watch strap pressure piece 4 is provided with a push-pull portion 41, and the watch strap pressure piece 4 can be slidably arranged on the watch case 1 along a first direction to extend into or exit the groove 111, wherein the first direction is a direction perpendicular to the side of the watch strap 2; the elastic piece 5 is connected between the watch strap pressure piece 4 and the watch case 1, when the push-pull portion 41 is not subjected to external force, the elastic force of the elastic piece 5 causes the watch strap pressure piece 4 to press the connector 3, and when the push-pull portion 41 is subjected to external force, causing the watch strap pressure piece 4 to compress the elastic piece 5, the watch strap pressure piece 4 releases the connector 3.

[0036] That is to say, under normal use, Figure 2 As shown, the strap pressing member 4 presses the connecting member 3 under the elastic force of the elastic member 5, thereby fixing the connecting member 3 to the watch case 1, that is, fixing the strap 2 to the watch case 1. When the strap 2 needs to be removed, an external force is applied to the push-pull portion 41 along the first direction, so that the strap pressing member 4 compresses the elastic member 5, thereby putting the elastic member 5 in a compressed state (as shown in FIG. Figure 3 As shown), at this time, the strap pressure piece 4 releases the connector 3, so the strap 2 together with the connector 3 can be taken out from the groove 111 of the watch case 1 to achieve disassembly of the strap 2.

[0037] When assembling the watch strap 2 and the watch case 1, an external force is applied to the push-pull portion 41 along the first direction, so that the watch strap pressure piece 4 compresses the elastic piece 5, thereby putting the elastic piece 5 in a compressed state. At this time, the watch strap pressure piece 4 withdraws from the groove 111 to make way for the installation of the connecting piece 3, so that the connecting piece 3 can be placed in the groove 111 of the watch case 1; then, the push-pull portion 41 is released, so that the watch strap pressure piece 4 is reset under the elastic force of the elastic piece 5, pressing the connecting piece 3, thereby realizing the assembly of the watch strap 2 and the watch case 1.

[0038] The thong 3 is pressed against the wristband 2 and the wristband 2 is fixed to the wristband 2 by the elastic force of the elastic member 5. When the thong 2 is removed from the wristband 2, an external force only needs to be applied to the push-pull portion 41 in the first direction to compress the elastic member 5. The thong 2 can be installed and removed. It can be seen that the thong 2 of the wristband 2 is easy to install and remove, and it is convenient to replace the thong 2. In addition, the thong 2 is fixed by clamping the connector 3. On the one hand, the structural strength of the connector 3 can be improved to ensure the reliability of the fixation of the thong 2. On the other hand, the clamping method is not easy to damage the connector 3 and the wristband 2. In addition, in the prior art, there is a quick release key that relies on the elastic deformation of the parts to realize the disassembly of the thong 2. This disassembly method is prone to damage to the parts over time and has poor durability. The present application adopts the above method to fix the thong 2, which can avoid deformation of the thong 2 after long-term use, and has good durability and long service life.

[0039] It should be noted that this embodiment does not limit the specific arrangement of the watchband pressing piece 4 on the watch case 1, as long as it can ensure that the watchband pressing piece 4 can be slidably arranged on the watch case 1 along the first direction.

[0040] In some embodiments, the watch case 1 is provided with a dovetail groove 112 (e.g. Figure 4 As shown), the strap pressing piece 4 is provided with a first boss 42 (as shown) which is slidably matched with the dovetail groove 112. Figure 5 As shown in FIG. 1 , it is understood that the relative sliding direction between the first boss 42 and the dovetail groove 112 is a first direction, thereby ensuring that the watchband pressure member 4 can slide in the first direction. Furthermore, the dovetail groove 112 also limits the first boss 42 in a second direction. The second direction is perpendicular to the top surface of the watch case 1, or at a predetermined angle with the top surface of the watch case 1, thereby preventing the watchband pressure member 4 from separating from the watch case 1 in the second direction.

[0041] For ease of understanding, Figure 4 As shown, the first direction is the X-axis direction, and the second direction is the Z-axis direction.

[0042] Furthermore, in some embodiments, the watch case 1 is provided with a first buckle 113 (such as Figure 4 As shown), the strap pressure piece 4 is provided with a second buckle 43 (as shown) for cooperating with the first buckle 113 to limit the position. Figure 5 As shown), to prevent the strap pressing piece 4 from separating from the watch case 1 along the first direction.

[0043] That is, during assembly, the second buckle 43 is elastically deformed to engage with the first buckle 113, thereby allowing the watchband pressure piece 4 to be installed in the watch case 1. After the first buckle 113 and the second buckle 43 are engaged, the watchband pressure piece 4 can slide in the first direction. When the watchband pressure piece 4 moves to its maximum position along the first direction toward the extension direction of the elastic member 5, the mechanical limit of the first buckle 113 can stop the second buckle 43, thereby preventing the watchband pressure piece 4 from separating from the watch case 1 in the first direction due to the elastic force of the elastic member 5.

[0044] Please refer to Figure 6 and 7 In order to facilitate the application of external force to the push-pull portion 41, in some embodiments, the push-pull portion 41 is a raised portion provided on the top of the strap pressure piece 4. In other words, the push-pull portion 41 protrudes from the top of the strap pressure piece 4. When an external force is applied to the push-pull portion 41, the strap pressure piece 4 can be moved along the first direction by pushing the raised portion, making it easier for a person to apply external force to the push-pull portion 41 and making the operation convenient.

[0045] In addition, in order to facilitate the positioning of the elastic member 5, ensure the correctness of the elastic member 5's expansion and contraction direction, and prevent the elastic member 5 from tilting, etc. Figure 4 As shown, in some embodiments, the watch case 1 is provided with a first limiting groove 114 for accommodating the elastic member 5. It should be noted that when the elastic member 5 is extended, it can be partially disposed within the first limiting groove 114. When the elastic member 5 is in a compressed state, it can be precisely retracted into the first limiting groove 114. At this time, the watchband pressure member 4 is in contact with the end surface of the first limiting groove 114, which helps to ensure the stability of the watchband pressure member 4.

[0046] It should be noted that the various embodiments of the present invention do not limit the specific structure of the elastic member 5. In some embodiments, the elastic member 5 is a spring.

[0047] In addition, the above embodiments do not limit the specific connection method between the connector 3 and the strap 2. Figure 1 In some embodiments, the connector 3 includes an embedding portion 31, which is embedded in the strap 2 (e.g. Figure 8 and 9 That is, in this embodiment, the embedding portion 31 is embedded in the watchband 2 to achieve connection between the connector 3 and the watchband 2, avoiding the need for an additional connection structure on the watchband 2 and facilitating the connection between the connector 3 and the watchband 2. It should be noted that the embedding portion 31 can be directly embedded in the watchband 2 during the molding process of the watchband 2.

[0048] In order to improve the stability of the connection member 3 and the watch case 1, in some embodiments, the bottom of the connection member 3 is provided with a second boss 32 (such as Figure 8 As shown), the watch case 1 is provided with a second limiting groove 115 (as shown) for cooperating with the second boss 32 to limit the position. Figure 4 That is, when the connector 3 is placed in the groove 111 of the watch case 1, the second boss 32 is placed in the second limiting groove 115, and the second limiting groove 115 is used to limit the connector 3, so as to realize the positioning of the watch strap 2 along the third direction, which is the length direction of the watch strap 2 (as shown in FIG. Figure 4 As shown, the third direction is the Y-axis direction), preventing the strap 2 from detaching from the watch case 1 along the third direction.

[0049] Furthermore, in some embodiments, a limiting step 33 is provided on the top of the connecting member 3 (eg Figure 8 As shown), the strap pressing piece 4 is provided with a third boss 44 (as shown) for cooperating with the limiting step 33 to limit the position. Figure 1 That is, after the connector 3 and the strap pressure member 4 are assembled, the third boss 44 cooperates with the limiting step 33 to limit the position of the connector 3 along the second direction, thereby using the strap pressure member 4 to prevent the connector 3 from falling out of the top of the watch case 1. The second direction has been defined above.

[0050] In addition, the above embodiments do not limit the specific structure of the watch case 1. For the purpose of wearing comfort, Figure 1 As shown, in some embodiments, lugs 11 are provided at each end of the watch case 1. Lugs 11 are tilted and have grooves 111 disposed therein. These grooves include a clamping groove for receiving the connector 3 and a supporting groove for supporting the watch strap 2. The supporting grooves extend from the clamping grooves toward the length of the watch strap 2. It will be appreciated that lugs 11 are tilted downward along the ends of the watch case 1, which facilitates a snug fit on the wrist and provides a comfortable fit. Furthermore, the grooves 111, along with the corresponding strap pressure piece 4 and elastic piece 5, are disposed therein to avoid interference with other functional components of the watch case 1 and prevent the watch case 1 from becoming excessively large. Furthermore, the groove 111 includes a clamping groove portion and a supporting groove portion, that is, the connector 3 is arranged in the clamping groove portion, and the portion of the strap 2 close to the connector 3 is arranged in the supporting groove portion, so that the lug 11 can be used to support the strap 2. At the same time, the groove wall of the clamping groove portion can also be used to limit the side of the strap 2 close to the connector 3, which is beneficial to improving the stability of the fixation of the strap 2.

[0051] It should be noted that, in the above embodiments, the specific number of the strap pressure piece 4 and the elastic piece 5 is not limited. Considering the stability and reliability of the strap 2, please continue to refer to Figure 1In some embodiments, the number of strap pressure members 4 and elastic members 5 corresponding to a single groove 111 is two, respectively. The single strap pressure member 4 and the single elastic member 5 form an elastic assembly. The two elastic assemblies corresponding to the single groove 111 are arranged opposite each other, so that the two strap pressure members 4 clamp the connector 3. In other words, this embodiment uses two strap pressure members 4 to clamp the connector 3, that is, the connector 3 exerts a squeezing force on both sides of the strap pressure member 4, so that the force on the connector 3 is more balanced and the fixation is more reliable.

[0052] Of course, in other embodiments, the number of strap pressure pieces 4 and elastic pieces 5 corresponding to a single groove 111 may also be one, that is, the strap pressure piece 4 and the elastic piece 5 form an elastic component, and the strap pressure piece 4 is used to press one side of the connecting piece 3, and the other side of the connecting piece 3 facing away from the strap pressure piece 4 is in contact with the groove wall of the groove 111.

[0053] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The wrist-worn device provided by the present invention has been introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be noted that, for those skilled in the art, various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
