[0012] Currently, smart glasses typically require the installation of electronic components inside the temple housing. Therefore, the temple housing is generally composed of two half-shells joined together. After the electronic components are installed, the two half-shells need to be glued together point by point. Then, a pressure holding process is performed on the joined temple housing to ensure that the two half-shells are firmly connected. However, the traditional pressure holding process requires operating two pressure holding components separately to perform pressure holding operations on the two temple housings one after the other, which is inefficient and affects the production efficiency of smart glasses products.

[0013] In view of this, the present invention provides a pressure-holding device, which can at least improve the problem of low pressure-holding efficiency in the current pressure-holding operation method for the temple shell of smart glasses. To facilitate understanding of the pressure-holding device provided by the present invention, it is described below in conjunction with the accompanying drawings, wherein... Figure 1 A three-dimensional structural schematic diagram of an embodiment of the pressure-holding device provided by this utility model; Figure 2 for Figure 1 Schematic diagram of the exploded structure of the pressure holding device; Figure 3 for Figure 2 Exploded view of the mounting base and pressure holding assembly; Figure 4 for Figure 3 Exploded view of the pressure holding assembly.

[0014] Please see Figure 1In one embodiment of this utility model, the pressure-holding device 100 is used to hold the temple shell of smart glasses. The pressure-holding device 100 includes a mounting base 2, a pressure-holding component 3, and a driving component 5. The mounting base 2 is provided with two limiting members 21, which are respectively used to place the two temple shells of the smart glasses. The pressure-holding component 3 includes two pressure-holding members 31, which are respectively arranged at intervals with the corresponding limiting members 21 along the first direction X. The pressure-holding members 31 are configured to move closer to or further away from the corresponding limiting members 21 to cooperate with the limiting members 21 to clamp the corresponding temple shells. The driving component 5 includes a movable part 52 movably disposed on the mounting base 2. The movable part 52 is tractively connected to the two pressure-holding members 31. The movable part 52 is configured to drive the two pressure-holding members 31 to move synchronously closer to or further away from the corresponding limiting members 21.

[0015] The two limiting members 21 are used to place the two temple shells of the smart glasses. Typically, during the pressure-holding operation, the two temple shells are fully extended relative to the frame shell, meaning the relative direction of the two limiting members 21 is the length direction of the smart glasses' frame shell. The limiting members 21 allow the entire temple shell to be fully placed, such as... Figure 1 In the embodiment shown, the limiting member 21 has a certain extension length, or it can be used only for part of the temple housing. For example, the limiting member 21 may include a root limiting member 21, a middle limiting member 21, and a tail limiting member 21, which are used to place the root, middle, and tail of the temple housing, respectively. As long as it can work with the pressure holding member 31 to apply a uniform clamping force to multiple positions in the length direction of the temple housing, the two limiting members 21 can be set separately or can be two parts of the same main structure.

[0016] Considering that the two half-shells of the temple housing may have multiple splicing methods, for example, in the unfolded state of the temple housing relative to the frame housing, the two half-shells can be spliced ​​along the thickness direction of the temple housing (that is, spliced ​​along the length direction of the frame housing), and the two half-shells can also be spliced ​​along the width direction of the temple housing (that is, spliced ​​along the height direction of the frame housing). In this embodiment, the pressure-holding member 31 and the corresponding limiting member 21 are only spaced apart along the first direction X. The first direction X is also the splicing direction of the two half-shells of the frame housing. It can also be understood that this embodiment is not limited to the splicing form of the two half-shells of the temple housing of smart glasses.

[0017] The drive assembly 5 includes a movable part 52 movably disposed on the mounting base 2. The movable part 52 can move in various ways, including rotational movement and linear movement. This embodiment does not limit this. The movable part 52 can drive the two pressure-holding members 31 to move simultaneously closer to and further away from the corresponding limiting members 21 through its own movement. The transmission connection between the movable part 52 and the pressure-holding members 31 can also be varied, depending on the movement of the movable part 52. For example, when the movable part 52 is rotating, the structure that converts the rotational movement of the movable part 52 into the linear movement of the pressure-holding members 31 includes a gear and rack transmission structure, a lead screw and threaded sleeve transmission structure, etc. This embodiment does not limit this.

[0018] In the technical solution provided by this utility model, before the pressure holding process, the pressure holding member 31 and the limiting member 21 are spaced apart. The two limiting members 21 allow the two temple shells of the smart glasses to be placed separately. During the pressure holding process, the movement of the movable part 52 can simultaneously drive the two pressure holding members 31 to move closer to the corresponding limiting member 21, thereby clamping and stabilizing the temple shells they are responsible for, achieving the purpose of synchronously pressing the two temple shells, and improving the pressure holding efficiency. After the pressure holding is completed, the reverse movement of the movable part 52 can simultaneously drive the two pressure holding members 31 to move away from the corresponding limiting member 21, which is conducive to efficiently removing the smart glasses and improving the production efficiency of smart glasses products.

[0019] Please see Figure 2 and Figure 3 In some embodiments, two limiting members 21 are distributed along the first direction X, and two pressure-holding members 31 are disposed between the two limiting members 21.

[0020] In the aforementioned embodiments, the spacing direction between the pressure-holding member 31 and the limiting member 21 is defined as the first direction X, that is, the movement direction of the pressure-holding member 31 is the first direction X. In the above technical solution, the two limiting members 21 are further defined to be distributed along the first direction X, and the two pressure-holding members 31 are arranged between the two limiting members 21. That is, the space between the two limiting members 21 is fully utilized to arrange the pressure-holding member 31, making the structure of the pressure-holding device 100 more compact. At the same time, since the distribution direction of the two limiting members 21 and the spacing direction between the pressure-holding member 31 and the corresponding limiting member 21 are consistent, the pressure-holding device 100 can be applied to smart glasses in which the two half shells of the temple shell are spliced ​​along the thickness direction.

[0021] Please see Figure 3 and Figure 4 In some embodiments, the movable part 52 is movably disposed between the two pressure-holding members 31 along the second direction Y, and has a pressure-holding position and a pressure-relieving position; during the stroke from the pressure-relieving position to the pressure-holding position, the movable part 52 drives the two pressure-holding members 31 to move synchronously closer to the corresponding limiting member 21.

[0022] It should be noted that when the movable part 52 is in the pressure-holding position, the pressure-holding member 31 can work with the limiting member 21 to apply a stable clamping force to the temple housing. When the movable part 52 is in the pressure-relieving position, the pressure-holding member 31 can move away from the limiting member 21, thereby releasing the clamping of the temple housing. The first direction X and the second direction Y are usually two intersecting directions in a plane. The angle between the two directions can be any value between 0° and 180°. However, under normal circumstances, the two directions are perpendicular to each other, that is, the angle is 90°. There are various structures that can convert the linear movement of the movable part 52 along the second direction Y into the linear movement of the pressure holding member 31 along the first direction X, such as the inclined plane push transmission structure or the pulley cable transmission structure. In this embodiment, the transmission form between the movable part 52 and the pressure holding member 31 is not limited. During the stroke from the pressure relief position to the pressure holding position, the movable part 52 drives the two pressure holding members 31 to move synchronously closer to the corresponding limit member 21. Conversely, during the stroke from the pressure holding position to the pressure relief position, the movable part 52 drives the two pressure holding members 31 to move synchronously away from the corresponding limit member 21.

[0023] In the above technical solution, the limited movable part 52 is movably disposed between the two pressure holding members 31 along the second direction Y, which makes full use of the space between the two pressure holding members 31, further improving the compactness of the pressure holding device 100, and the overall space occupation requirement of the pressure holding device 100 is low.

[0024] For details regarding the specific operation methods of the active section 52 and the pressure-holding component 31, please refer to [link / reference needed]. Figure 3 and Figure 4 The mounting base 2 is provided with multiple slide rail structures 7, including a first slide rail 71 and multiple second slide rails 72. The first slide rail 71 extends along the second direction Y, and the second slide rail 72 extends along the first direction X. The movable part 52 is provided on the slide rail seat of the first slide rail 71, and the pressure holding member 31 is provided on the slide rail seat of the corresponding second slide rail 72.

[0025] Specifically, please refer to Figure 4 A linkage rod 6 is provided between the moving part 52 and the two pressure-holding components 31.

[0026] The movable part 52 and the pressure holding member 31 are driven by the linkage rod 6. Since the movable part 52 moves along the second direction Y and the pressure holding member 31 moves along the first direction X, it can be understood that the two ends of the linkage rod 6 are respectively hinged to the movable part 52 and the pressure holding member 31 along at least the third direction axis, which may include the form of ball joint universal joint.

[0027] In the above technical solution, in the transmission structure that transforms the linear motion of the movable part 52 along the second direction Y into the linear motion of the pressure-holding member 31 along the first direction X, the transmission form of the linkage rod 6 is relatively simple and direct, occupies less installation space, and has higher transmission efficiency, making it suitable for the small-volume structure of the pressure-holding device 100.

[0028] After the drive assembly 5 drives the movable part 52 to the pressure-holding position, it can maintain the position of the movable part 52 through its own locking function. For example, when the drive assembly 5 includes a drive cylinder, the extension rod of the drive cylinder pushes the movable part 52 to move. The drive cylinder can maintain the position of the movable part 52 by cutting off the air supply when the movable part 52 reaches the pressure-holding position. However, this drive assembly 5 has a high cost and the supporting facilities are relatively complex.

[0029] In view of this, please refer to Figures 1 to 3 In some embodiments, the movable part 52 is equipped with a locking part 521, and the mounting base 2 is provided with a fixing part 22 corresponding to the locking part 521; when the movable part 52 is in the pressure holding position, the locking part 521 is configured to be able to connect to the fixing part 22 and restrict the movable part 52 from moving toward the pressure relief position.

[0030] There are various ways to connect the locking part 521 and the fixing part 22, as long as the connection can restrict the movement of the movable part 52 toward the pressure relief position, for example in... Figure 2 In the embodiment shown, the locking part 521 is a locking buckle, and the fixing part 22 is a fixing rod. The locking buckle and the fixing rod are arranged along the second direction Y. When the movable part 52 is in the pressure-holding position, it can be fastened to the fixing rod by pressing the locking buckle. Thus, the connection between the locking buckle and the fixing rod continuously provides the movable part 52 with a force along the second direction Y and resists the reaction force exerted by the pressure-holding member 31 on the movable part 52 during the pressure-holding process, thereby making the movable part 52 stably maintain in the pressure-holding position.

[0031] In the above technical solution, the locking part 521 and the fixing part 22 are configured to keep the movable part 52 in the pressure-holding position by means of mechanical locking. Based on this, the specific driving form of the driving component 5 has more possibilities. For example, the movable part 52 can be manually pushed to change its position. After the pressure holding time, the two half shells of the temple are firmly bonded together. The connection between the locking part 521 and the fixing part 22 can be released. Under the reaction force of the pressure-holding member 31, the movable part 52 can move towards the pressure-relief position on its own, thereby releasing the clamping of the temple shell.

[0032] Please see Figure 2In some embodiments, the pressure holding device 100 further includes a positioning seat 1, which has a positioning area 1a, and the mounting seat 2 is positioned in the positioning area 1a; the drive assembly 5 includes a drive structure 51, which is disposed on the positioning seat 1 and has a drive part that is telescopically movable along the second direction Y, and the drive part abuts against the movable part 52.

[0033] There are many ways to position the "mounting base 2" in the positioning area 1a of the positioning base 1. For example, the mounting base 2 can have a positioning hole, and the positioning area 1a of the positioning base 1 can have a positioning pin. Positioning can be achieved by the insertion and engagement of the positioning hole and the positioning pin. Another example is... Figure 2 In the embodiment shown, the positioning area 1a can be enclosed by setting a limiting edge and a limiting block, which can also realize the positioning of the positioning seat 1 in the positioning area 1a.

[0034] The specific structural forms of "drive structure 51" are numerous, for example, in Figure 2 In the embodiment shown, the drive structure 51 is a quick clamp 51a, which is manually driven. Of course, the drive structure 51 can also adopt an automatic drive structure such as a drive cylinder.

[0035] In the above technical solution, considering the driving structure 51 set on the positioning seat 1, the mounting seat 2 positioned on the positioning seat 1, and the cooperation between the locking part 521 and the fixing part 22, it can be seen that multiple pressure-holding bodies composed of the mounting seat 2, the pressure-holding component 3, and the moving part 52 can be set up, and they can all use the same set of positioning seats 1 and driving structure 51. After the pressure-holding clamping operation of the temple shell of the smart glasses on a set of pressure-holding bodies is completed, it can be removed from the positioning seat 1 and placed for pressure holding alone. Then, another set of pressure-holding bodies can be replaced to use the positioning seat 1 for pressure-holding clamping operation, which improves the utilization rate of the positioning seat 1 and the driving structure 51.

[0036] Please see Figure 3 In some embodiments, an elastic reset member 4 is further provided between the pressure holding member 31 and the limiting member 21. The elastic reset member 4 is configured to drive the pressure holding member 31 away from the limiting member 21.

[0037] The "elastic reset component 4" is a structure that is elastic and can independently drive the pressure holding component 31 to move. Since its position is between the pressure holding component 31 and the limiting component 21, when the pressure holding component 31 approaches the limiting component 21, the elastic reset component 4 can accumulate elastic potential energy. When the pressure holding device 100 stops holding pressure, the elastic reset component 4 can actively drive the pressure holding component 31 away from the limiting component 21, thereby helping to release the pressure holding limit on the smart glasses.

[0038] exist Figure 3In the embodiment shown, the elastic reset member 4 is a spring and is sleeved on the mounting rod provided on the limiting member 21. The pressure holding member 31 has a mating hole that cooperates with the mounting rod. As the pressure holding member 31 approaches the limiting member 21, the mounting rod continuously extends into the mating hole, and the spring is continuously compressed by the pressure holding member 31 and the limiting member 21.

[0039] Please see Figure 3 In some embodiments, the pressure-holding member 31 includes a mounting portion 311 and a plurality of pressure-holding portions 312. The mounting portion 311 is tractively connected to the movable portion 52. The plurality of pressure-holding portions 312 are distributed along the second direction Y on the mounting portion 311 and are used to cooperate with the limiting member 21 to clamp the temple housing. The plurality of pressure-holding portions 312 are configured to be positionally adjustable in the first direction X.

[0040] The "pressure holding section 312" is adjustable in the position of the first direction X, and there are various ways to adjust it, such as... Figure 4 In the embodiment shown, the pressure holding part 312 is connected to the mounting part 311 by an adjusting bolt. The position of the pressure holding part 312 can be steplessly adjusted by turning the adjusting bolt. Of course, the pressure holding part 312 can also be adjusted by selectively connecting one of the multiple connecting holes distributed along the first direction X to the mounting part 311. This embodiment does not limit this.

[0041] In the above technical solution, the multiple pressure-holding parts 312 are components that actually cooperate with the limiting member 21 to clamp the temple housing. The multiple pressure-holding parts 312 are distributed along the second direction Y and their positions along the first direction X are adjustable. By individually adjusting the positions of the multiple pressure-holding parts 312, the shape of the temple housing can be precisely adapted to apply a uniform clamping force to the temple housing.

[0042] Specifically, the limiting member 21 is also detachably mounted on the mounting base 2. By replacing the limiting member 21 with different shapes, and with the adjustable position function of multiple pressure holding parts 312, the pressure holding device 100 can be adapted to the temple shells of various types of smart glasses.

[0043] Please see Figure 4 In some embodiments, the pressure-holding portion 312 includes a base portion 3121 and an elastic contact portion 3122. The base portion 3121 is disposed on the mounting portion 311, and the elastic contact portion 3122 is disposed on the side of the base portion 3121 near the limiting member 21.

[0044] The base part 3121 provides a mounting base for the elastic contact part 3122, which is the part on the pressure holding part 312 that directly contacts the temple housing. The material of the elastic contact part 3122 should be elastic, such as rubber or silicone.

[0045] In the above technical solution, during the process of the pressure-holding part 312 abutting against the temple housing, the elastic contact part 3122 can compensate for manufacturing tolerances through its own elastic deformation, thereby ensuring full contact between the pressure-holding part 312 and the temple housing.

[0046] Please see Figure 3 In some embodiments, the mounting part 311 includes a main body part 3111 and a replacement part 3112. The main body part 3111 is tractively connected to the movable part 52. The replacement part 3112 is detachably disposed on the main body part 3111, and a plurality of pressure-holding parts 312 are disposed on the replacement part 3112.

[0047] The main body 3111 is connected to the movable part 52, that is, the driving force of the movable part 52 acts on the main body 3111, and the main body 3111 and the mounting base 2 are movablely engaged in the first direction X.

[0048] In the above technical solution, by setting the mounting part 311 to a structure in which the replacement part 3112 and the main body part 3111 can be separated, the main body part 3111, which serves as the basis for the movement, can remain unchanged during the product change process. By replacing the replacement part 3112 with the pressure-holding part 312, it can be adapted to the corresponding type of smart glasses product, thereby expanding the applicability of the pressure-holding device 100.

[0049] In one specific embodiment, the pressure-holding device 100 includes a positioning seat 1, a mounting seat 2, a pressure-holding component 3, and a driving component 5. The positioning seat 1 is provided with a positioning area 1a, and the mounting seat 2 is positioned in the positioning area 1a. The mounting seat 2 is provided with two limiting members 21, which are distributed along a first direction X for placing the two temple housings of the smart glasses. The pressure-holding component 3 includes two pressure-holding members 31, which are disposed between the two limiting members 21 and are spaced apart from their corresponding limiting members 21 along the first direction X. The pressure-holding members 31 are configured to be able to approach or move away from their corresponding limiting members. 21 is active to cooperate with the limiting member 21 to clamp the corresponding temple housing; the pressure holding member 31 includes a mounting part 311 and a plurality of pressure holding parts 312. The mounting part 311 includes a main body part 3111 and a replacement part 3112. The replacement part 3112 is detachably disposed on the main body part 3111. The plurality of pressure holding parts 312 are distributed along the second direction Y on the replacement part 3112. The plurality of pressure holding parts 312 are used to cooperate with the limiting member 21 to clamp the temple housing. The plurality of pressure holding parts 312 are configured to be adjustable in position in the first direction X; the pressure holding part 312 includes a base part 3121 and an elastic contact part 3122. The base part 3121 The replacement part 3112 is provided with an elastic contact part 3122, which is located on the side of the base part 3121 near the limiting member 21. An elastic reset member 4 is provided between the base part 3121 and the limiting member 21. The drive assembly 5 includes a quick clamp 51a provided on the positioning seat 1 and a movable part 52 provided on the mounting seat 2. The quick clamp 51a has a drive part that extends and retracts along the second direction Y. The drive part abuts against the movable part 52. The movable part 52 is movably disposed between the two pressure-holding members 31 along the second direction Y and is respectively driven and connected to the main body part 3111 of the two pressure-holding members 31 through two linkage rods 6. The movable part 52 has a pressure holding position and a pressure releasing position within its active stroke. During the stroke from the pressure releasing position to the pressure holding position, the movable part 52 drives the two pressure holding members 31 to move synchronously closer to the corresponding limit member 21. During the stroke from the pressure holding position to the pressure releasing position, the movable part 52 drives the two pressure holding members 31 to move synchronously away from the corresponding limit member 21. The movable part 52 is equipped with a locking part 521, and the mounting base 2 is provided with a fixing part 22 corresponding to the locking part 521. When the movable part 52 is in the pressure holding position, the locking part 521 is configured to be able to connect to the fixing part 22 and restrict the movable part 52 from moving toward the pressure releasing position.
