The main inventive concept of the disclosed embodiments is to provide a structure for making a connection member to a wrist band more firmly and a method of manufacturing the same, so that a specific form of the wrist band connection member is not necessarily limited, and may be any connection member suitable for being provided on a wrist band.

In current correlation technique, it is fixed to adopt the bonding mostly between wrist strap connecting piece and the wrist strap, for example the knitting wrist strap that materials such as nylon, spandex were made, wrist strap connecting piece (mostly metallic material) bonds on knitting the wrist strap through glue or the mode of hot bonding, and the mode reliability of bonding is relatively poor, connects the position and takes place to drop easily after wearing for a long time. Some wrist strap connectors are fixed with the wrist strap through compression joint of mechanical structures, such as a silica gel wrist strap and a metal connector, the mechanical structures are arranged on the connectors, the connectors and the wrist strap are compressed together through pressing the mechanical structures, after the structure is used for a long time, the wrist strap generates flexible deformation, pressing force is reduced, the risk of falling still exists, and the risk of falling is also generated after the mechanical connection structures are touched by mistake or used repeatedly.

Based on the above-mentioned defects existing in the prior art, the embodiments of the present disclosure provide a wrist strap connecting structure that enables the connection between the wrist strap and the wrist strap connector to be more stable and reliable.

In some embodiments, the wristband connecting structure of the present disclosure includes a wristband and a wristband connector, wherein a plurality of connecting holes penetrating through the wristband in the thickness direction are formed in an end portion of the wristband, for example, a woven wristband made of nylon material may be laser engraved in the end portion of the wristband. The wrist strap connecting piece comprises a first connecting portion and a second connecting portion, a plurality of fixing pins which are matched with the connecting holes in the wrist strap in shape and correspond to the connecting holes in position are arranged on the first connecting portion, and therefore the fixing pins and the connecting holes are connected in a one-to-one inserting mode. One end of the fixing pins, which is far away from the first connecting part, is connected to the second connecting part, namely, the wrist strap connecting piece and the wrist strap are in the plane direction of the wrist strap, and the fixing pins and the connecting holes can be used for realizing the limiting; and on the direction of perpendicular to wrist strap plane, first connecting portion and second connecting portion carry on spacingly to the wrist strap to realize the fixed connection of wrist strap connecting piece and wrist strap. The first connecting portion, the plurality of fixing pins and the second connecting portion are of an integrally formed structure, for example, the wrist strap connecting piece can be made of injection molding materials, and the wrist strap connecting piece is fixedly sleeved on the wrist strap through twice injection molding.

Through the aforesaid can know, in this disclosure's embodiment's wrist strap connection structure, the position of being connected with the wrist strap on the wrist strap connecting piece is integrated into one piece to accomplish after the assembly with the wrist strap, do not receive under the condition of violence destruction at wrist strap and wrist strap connecting piece, both can not appear droing, compare in the connection structure of bonding and crimping, this disclosure's embodiment's connection structure is more stable firm.

Some embodiments of the wristband coupling structure and the wristband assembly according to the present disclosure are illustrated in fig. 1 to 5, and the structure and principle of the wristband coupling structure and the wristband assembly according to the embodiments will be described in detail with reference to fig. 1 to 5.

The overall structure of the wristband assembly in this embodiment is shown in fig. 1. As shown in fig. 1, the wristband assembly includes a wristband 100, and in the present embodiment, the wristband 100 is illustrated as a nylon woven wristband. However, it is understood that the wrist band 100 in the present disclosure is not limited to a nylon woven wrist band, but may be any wrist band suitable for implementation, such as a woven wrist band made of other materials, or a silicone wrist band, a metal wrist band, etc., and the present disclosure will not be described in detail herein.

A wrist band connector is connected to each end of the wrist band 100, and the wrist band connector in this embodiment includes a first head connector 220 and a tail connector 210. The first head connector 220 is used for connecting the wrist band 100 with the head, and the tail connector 210 is used for protecting the tail of the wrist band 100 by wrapping, so that the woven wrist band is prevented from being scattered, and the wrist band is convenient for a user to wear. It should also be understood that the wrist strap connector in the embodiments of the present disclosure is not limited to the two types shown in the present embodiment, and any other connector suitable for implementation may be used, and the details of the present disclosure are not repeated here.

In the present embodiment, the wrist band connecting member molding method is described by taking injection molding as an example, and therefore, the wrist band connecting member is made of an injection molding material such as plastic or rubber. It will also be appreciated by those skilled in the art that other materials may be used for other integral molding processes, such as a 3D printing integral molding process, and that the wristband attachment may likewise be of a material suitable for 3D printing. As such, the wristband attachment of the present disclosure is not limited to the present embodiment. In the following embodiments, the wrist band connecting member is described by taking a plastic material as an example in consideration of material cost and strength requirements.

As shown in fig. 2a to 2c, the wristband attaching structure will be described by taking the tail connector 210 as an example. As shown in fig. 2a, a plurality of connection holes 111 are formed through the wrist band 100 at the end of the wrist band 100. It should be noted that in the embodiments of the present disclosure, the number of the connection holes 111 may be at least one, that is, the present disclosure does not limit the specific number of the connection holes 111. In some preferred embodiments, the number of the connection holes 111 may preferably be at least two, considering that one connection hole is poorly restricted from circumferential rotation when being matched with the pin shaft. For example, in the present embodiment, the number of the connection holes 111 is set to 5 in order in the width direction of the wristband 100.

The belt tail connector 210 includes a first connection portion 211, and the first connection portion 211 is provided with a plurality of fixing pins 212 corresponding to the connection holes 111 in shape and position. For example, the first injection molding 500 shown in fig. 2a can be first formed by in-mold injection molding, and the first injection molding 500 is approximately a half structure of the band tail connector 210, which includes the first connecting portion 211, and the shape of the first connecting portion 211 is slightly larger than the width of the end of the wrist band 100, so that the tail of the wrist band 100 can be completely wrapped. The first connecting portion 211 is formed with a plurality of fixing pins 212, and the number of the fixing pins 212 may be less than or equal to the number of the connecting holes 111. Also, considering that one connection hole is poorly restricted in circumferential rotation in cooperation with the pin shaft, the number of the fixing pins 212 may preferably be at least two. For example, in the present embodiment, the fixing pins 212 are provided in one-to-one correspondence with the connection holes 111.

Then, as shown in fig. 2b, the first injection mold 500 may be assembled to the end of the wristband 100, that is, the fixing pins 212 are inserted into the connecting holes 111 in a one-to-one correspondence. At this time, the first injection molding 500 is already stopped by the fixing pin 212 and the coupling hole 111 in the wristband plane, and can be moved away only in a direction perpendicular to the wristband plane. Therefore, the first injection molding 500 assembled at the end of the wristband 100 is placed in the cavity of the injection mold for the second injection molding, and the second connecting portion 213 formed by the second injection molding is integrally formed with the free end of the fixing pin 212, i.e., the tail connecting member 210 integrally formed with the first injection molding 500.

After the second injection molding is completed, the assembly structure of the tail connector 210 and the wristband 100 is as shown in fig. 2 c. It can be seen that the band tail connector 210 and the band 100 are fixed by the fixing pin 212 and the connecting hole 111 in the plane of the band, and the band 100 is sandwiched between the first connecting portion 211 and the second connecting portion 213 in the direction perpendicular to the plane of the band, so that the first connecting portion 211 and the second connecting portion 213 fix and limit the band 100. Meanwhile, since the whole belt tail connector 210 is of an integrally formed structure, the belt tail connector 210 cannot be separated from the wrist strap 100 without damaging the structure, and thus the fixing connection between the two is more stable and firm.

Further, considering that the wristband 100 of the present embodiment is a woven wristband, the density of the woven wristband is low, and the wristband may have a reduced strength at the position where the connection hole 111 is formed, resulting in a risk of damage to the wristband 100. Therefore, in the present embodiment, the fitting portion 110 formed by hot press molding is provided at the position of the hole of the wristband 100.

Specifically, as shown in fig. 2a, before the wristband 100 is punched, the end of the wristband 100 is first heat-pressed to partially cure the heat-pressed area of the woven wristband, thereby increasing the density and increasing the hardness of the wristband. The hot pressing region serves as a mounting portion 110 for connecting the wrist band connector, and then a connection hole 111 is formed in the mounting portion 110 by, for example, laser etching, thereby making the connection structure more secure and reliable.

Fig. 3a to 3c show a connection structure of the first head connector 220 and the wrist band 100, and the main body concept is the same as that of the tail connector 210, and the tail connector 210 is not described in detail below.

As shown in fig. 3a, a plurality of connection holes 111 are also formed in the other end of the wristband 100, and the structure and principle of the connection holes 111 can be seen from the above. Also, the assembling portion 110 may be formed at the end of the wrist band 100 by hot pressing, and the connecting hole 111 may be formed on the assembling portion 110 by laser etching, so as to improve the structural strength of the wrist band 100, which will not be described herein.

The first head connecting member 220 serves to connect the head with the wrist band, and thus the first head connecting member 220 includes a third connecting portion for fitting connection with the head in addition to the first connecting portion 211, the second connecting portion 213, and the fixing pin 212 for fitting with the wrist band. Specifically, the first injection molding 500 shown in fig. 3a can be obtained by in-mold injection molding, and the first injection molding 500 corresponds to substantially a half structure of the first header connector 220. The first connecting portion 211 and the plurality of fixing pins 212 included in the first injection molding 500 can be referred to the tape tail connector, and are not described herein again.

The first injection mold 500 further has a first green ear groove 214 formed thereon, and the first green ear groove 214 is used for mounting a green ear assembly, so that the first watch head connector 220 can be hinge-mounted on one end of the watch head through the green ear assembly. Then, as shown in fig. 3b, the first injection mold 500 may be assembled at the end of the wrist band 100, that is, the fixing pins 212 are inserted into the connecting holes 111 in a one-to-one correspondence manner, and the above-mentioned tail connector 210 is referred to herein, and will not be described again.

The raw ear is a component for assembling the wrist strap, and two ends of the raw ear are inserted into assembling holes which are pre-opened on the watch head. The basic working principle of the raw ear is as follows: the end part of the wrist strap is provided with a mounting hole along the width direction, and the raw ear is placed in the mounting hole; two plug connectors are arranged at two ends of the lug, an elastic part is arranged in the lug, the elastic part is abutted against the plug connectors, the elastic part is in a normal compression state, and when the lug is not influenced by external force, the length of the lug is greater than the width of the gauge outfit assembling hole, so that the lug can be inserted on the gauge outfit, and the wrist strap is hinged with the gauge outfit; when compressing the plug connector with external forces such as instruments, the elastic component pressurized, the plug connector contracts back and gives birth to inside the ear to give birth to the ear and can break away from the gauge outfit and get off, make wrist strap and gauge outfit separation.

Then, when the first injection molding 500 is subjected to the second injection molding, there may be two ways:

1) the first rubber injection molding 500 assembled with the wristband 100 and the first raw ear assembly in the first raw ear groove 214 are placed into a mold together for secondary injection molding, the second connecting portion 213 formed by the secondary injection molding is integrally molded with the free end of the fixing pin 212, and the second raw ear groove formed by the secondary injection molding and the first raw ear groove 214 form the raw ear hole 221.

Give birth to ear subassembly direct injection moulding and form in giving birth to the ear hole, need not to assemble alone to giving birth to the ear, give birth to the ear simultaneously and can not take off the ear hole 221 of giving birth, need not to save alone to the ear subassembly, the wrist strap subassembly of being convenient for transports, stores and uses.

2) The first injection molding 500 assembled with the wristband 100 is placed in a mold for secondary injection molding, the second connecting portion 213 formed by the secondary injection molding is integrally formed with the free end of the fixing pin 212, and the second lug groove formed by the secondary injection molding and the first lug groove 214 are integrally formed into the lug hole 221. And then the formed first gauge head connecting piece is independently assembled with the raw ear assembly, namely, the raw ear assembly is assembled in the raw ear hole 221, so that the injection molding process is simplified.

As described above, the structure of the first head connector 220 connected to the wrist band 100 is similar to the tail connector 210, in the plane of the wrist band, the first head connector 220 and the wrist band 100 are fixed by the fixing pin 212 and the connecting hole 111, and in the direction perpendicular to the plane of the wrist band, the wrist band 100 is sandwiched between the first connecting portion 211 and the second connecting portion 213, so that the first connecting portion 211 and the second connecting portion 213 fix and fix the wrist band 100. Meanwhile, since the whole connector is an integrally formed structure, the first header connector 220 is not separated from the wrist band 100 without damaging the structure, so that the fixed connection between the two connectors is more stable and secure.

In the present embodiment, the connection structure and the processing method of the wristband connector and the wristband are explained. In other embodiments, the wristband connector may also adopt other integrated forming manners, such as 3D printing, and the 3D printing may also realize the integrated forming processing of the wristband connector, and those skilled in the art may realize the connection structure of the present disclosure by combining the 3D printing related technology on the basis of the disclosure of the above embodiments, and details are not repeated herein.

Further, the above-mentioned raw ear assembly of the first watch head connecting part 220 is easy to be pulled out of the raw ear hole when the wrist band is not engaged with the watch head because the general raw ear assembly is simply placed in the raw ear hole. Therefore, the wristband assembly still needs to be stored separately when being sold or stored, and the ear generating assemblies of some watches are still non-standard pieces and cannot be used once the whole wristband is lost. In view of the problem that the raw ear assembly is easily detached from the connector, as shown in fig. 4, the first header connector for preventing the raw ear from being detached is provided in the present embodiment.

The ear generating assembly comprises a generating ear 223 positioned in the generating ear hole and plug connectors 224 arranged at two axial ends of the generating ear 223, an elastic part is further arranged in the generating ear, and the assembly principle of the elastic part and the plug connectors 224 is the same as that described above, and the details are not repeated here. The lug generating assembly of the present embodiment further includes a driving lever 225, the driving lever 225 is fixedly connected to the plug connector 224 along the radial direction, specifically, an avoiding groove 226 may be formed on a side wall of the lug, and the avoiding groove 226 is located at a position corresponding to the plug connector 224, so that the driving lever 225 may be fixed to the plug connector 224 by screwing or pin-jointing through the avoiding groove 226 after the lug generating assembly is completed. Meanwhile, when the shifting lever 225 is shifted along the generating lug in the axial direction, the plug connector 224 can be retracted, and the meter head can be assembled and disassembled. Similarly, the side wall of the ear generating hole 221 is correspondingly provided with a avoiding hole 222, so that the shift lever 225 can have a certain moving space.

The working principle is as follows: when the driving lever 225 is not subjected to external force, the plug-in components 224 at the two ends of the lug 223 extend out of the lug hole 221 under the action of elastic force, and then the assembly with the watch head can be realized.

And for the assembly of the raw lug assembly, the two processing modes can be realized, the raw lug assembly can be embedded into a mold for secondary injection molding, and the assembly of the raw lug assembly can be completed after the secondary injection molding. For example, taking the example that the raw ear assembly is embedded in the mold and is subjected to the secondary injection molding at the same time, the raw ear assembly is placed in the first raw ear groove 214, and then is placed in the mold together for the secondary injection molding. For another example, taking the secondary injection molding and then assembling the raw ear assembly as an example, after the connecting member is molded, the raw ear may be inserted into the raw ear hole, the avoidance groove 226 on the raw ear corresponds to the avoidance hole 222, and then the shift lever is installed at the avoidance hole 222, that is, the shift lever is fixed on the insertion portion by means of insertion or screw connection, so as to complete the raw ear assembly. It will be understood by those skilled in the art that the details are not repeated.

Therefore, the shifting rod 225 and the avoiding hole 222 form a limiting structure in the axial direction, so that the ear generating assembly cannot be separated from the ear generating hole 221, the ear generating assembly does not need to be stored separately, and the wrist strap is more convenient to assemble and use. And adopt driving lever 225 to promote the flexible of living ear, need not to adopt special mounting tool for the assembly of gauge outfit and wrist strap connecting piece is convenient and fast more.
