Description

Technical Field

[0001] This application relates to the field of wearable device technology, and further to a host structure and wearable device. Background Technology

[0002] In recent years, with the continuous development and innovation of electronic technology, my country's smart host industry has developed rapidly; smart wearable devices, represented by smartwatches, have become an indispensable part of modern production and life.

[0003] However, most smart wearable devices on the market, such as smartwatches, still offer insufficient user convenience in certain scenarios due to their limited setup options. For example, when making voice calls or taking photos with a smartwatch, users often need to adjust their arm to a specific posture or remove the device from their wrist to meet the required call distance or shooting angle, making the process rather cumbersome. In response, some manufacturers have attempted to design a separate or rotating connection between the smartwatch's main unit and the wristband to improve ease of use; however, such solutions often come with complex structures, high production difficulty, and increased costs. They also tend to increase the size and weight of the device, contradicting the increasingly prominent trend of "thinner and lighter" smart wearable devices, and require further improvement and optimization. Utility Model Content

[0004] The purpose of this application is to provide a host structure and wearable device, which realizes the split and rotating connection between the host of the wearable device and the tray through a simple structure, thereby improving the ease of use, effectively reducing the production difficulty and cost of the corresponding wearable device, and promoting its development towards thinner and lighter designs.

[0005] The technical solution provided in this application is as follows:

[0006] On the one hand, this application provides a host architecture, including:

[0007] The main unit and the support plate for supporting the main unit;

[0008] A connecting component, disposed between the main unit and the tray, for connecting the main unit and the tray, includes a slide rail and a slide base;

[0009] One of the main unit or the tray is provided with the slide rail, and the other of the main unit or the tray is provided with the slide base. The slide base is provided correspondingly to the slide rail and is adapted to be inserted into the slide rail from one end of the slide rail, and slides and engages with the inner wall of the slide rail along the length direction of the slide rail, so as to detachably connect the main unit and the tray.

[0010] And, the slide block is adapted to rotate around its own axis and engage with the inner wall of the slide block after sliding into position relative to the slide rail, so as to change the pitch angle of the main unit relative to the tray.

[0011] The host structure provided in this application allows the user to hold the host and the tray with both hands, insert the slide block into the slide channel from one end, and then push the host and the tray relative to each other along the length of the slide channel until the slide block moves to a preset position within the slide channel, thus assembling the host relative to the tray. Afterwards, the corresponding wearable device is worn on the corresponding part of the body for regular use. In certain specific usage scenarios, such as when the wearable device is a smartwatch and needs to be used for making calls or taking photos, the user again pushes the host and the tray relative to each other along the length of the slide channel until the slide block detaches from the slide channel, allowing the host to be removed from the corresponding wearing part for voice calls. The device allows for various operations such as taking photos; alternatively, the user can move the main unit relative to the tray, causing it to rotate around the axis of the slide block relative to the inner wall of the slide, adjusting the angle of the main unit relative to the tray to meet the viewing angle requirements for video calls, taking photos, etc. In this way, users do not need to adjust their arms to a special posture or remove the smartwatch or other wearable device from the wearing part. By pushing the corresponding tray of the main unit to slide in a straight line or rotate around the axis, the corresponding operation requirements in specific usage scenarios can be met. The structure is simple, and the related operations are convenient and comfortable. At the same time, the simplified connection structure between the main unit and the tray facilitates the development of the entire wearable device towards lightweight and miniaturization, which not only helps enterprises reduce costs and increase efficiency, but also effectively improves the user experience.

[0012] In some embodiments, the connection assembly includes a first connector and a second connector, wherein the first connector is detachably disposed at one end of the host and the second connector is detachably disposed at one end of the tray;

[0013] The first connector includes a gripper, the gripper having a C-shaped structure, and the slide rail being formed on the concave surface of the gripper;

[0014] The second connecting member includes a slide rod and a support arm;

[0015] The slide rod has a cylindrical structure, its axis is parallel to the support plate, its radial dimension is adapted to the inner diameter of the gripper, and it forms the slide seat; the support arm is perpendicular to the support plate, one end of which is connected to the support plate, and the other end is connected to the outer circumferential surface of the slide rod near the support plate.

[0016] A damping structure is provided between the gripper and the slide bar.

[0017] In some embodiments, the support arm is connected to the middle of the slide bar in the axial direction;

[0018] The gripper has a limiting groove in the middle of the slide rail along its length. The opening of the limiting groove is connected to the C-shaped opening of the gripper so as to embed the support arm when the slide block slides into place relative to the slide rail and rotates relative to the inner wall of the slide rail.

[0019] In some embodiments, both ends of the slide rod are formed with chamfered bevels so that the slide block can be inserted into the slide track from one end of the slide track.

[0020] In some embodiments, the host computer has a cantilever formed at one end where the gripper is located. The cantilever is located on the side of the host computer away from the tray in the thickness direction and forms a mounting groove with the end wall of the host computer where the gripper is located.

[0021] The gripper is detachably mounted in the mounting groove by a fixing member, and its C-shaped opening is kept facing the end of the slide block mounted on the host.

[0022] The limiting groove is located on the claw arm on the side of the gripper away from the cantilever.

[0023] In some embodiments, the first connector further includes a positioning arm connected to the convex surface of the gripper;

[0024] The inner wall of the mounting groove is provided with a positioning groove, and the positioning arm is fitted into the positioning groove according to the size of the positioning groove, and is detachably connected to the main unit through the fixing member.

[0025] In some embodiments, a connecting groove is provided on the tray, and one end of the support arm away from the slide rod is embedded in the connecting groove and detachably connected to the tray.

[0026] In some embodiments, one end of the support arm that extends into the connecting groove is fixedly connected to the tray by fasteners.

[0027] In some embodiments, one end of the support arm that extends into the connecting groove is rotatably connected to the tray, and the axis of rotation is perpendicular to the tray.

[0028] On the other hand, this application also provides a wearable device, including:

[0029] The watch strap and any of the aforementioned host structures;

[0030] The watch strap has two ends, which are respectively connected to the opposite ends of the tray.

[0031] Compared with the prior art, the host structure and wearable device provided in this application have the following advantages:

[0032] This application utilizes the sliding and rotating cooperation of the slide base and the slide rail to achieve the separation, assembly, and rotational connection between the main unit and the tray of the corresponding smart wearable device. While simplifying the connection structure between the main unit and the tray, it ensures the diversity of the setting forms of the corresponding wearable device, enabling smartwatches and other corresponding smart wearable devices to meet the operational needs in different usage scenarios. Moreover, the related operations are convenient and comfortable, effectively improving the user experience. At the same time, due to the simple connection structure between the main unit and the tray, it not only reduces the production difficulty and cost for enterprises, but also effectively promotes the development of the corresponding wearable device towards lightweight and miniaturization, thereby further optimizing the user experience.

[0042] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0043] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0044] In recent years, some manufacturers in the smart device industry have attempted to design the main unit and tray of smartwatches and other smart wearable devices as separate or rotating connections to enrich the device's configuration options and enhance the user experience. However, the connection structure between the main unit and tray in these technologies is usually quite complex, resulting in high production difficulty and cost for smartwatches and other smart wearable devices. This also hinders the miniaturization and weight reduction of these devices, and there are areas for improvement.

[0045] In one embodiment, reference is made to the accompanying drawings. Figures 1 to 6 A host structure is provided, including a host 1, a tray 2 for supporting the host 1, and a connecting component 3 connecting the two. The connecting component 3 is disposed between the host 1 and the tray 2, and includes a slide rail 3111 and a slide base 3211; one of the host 1 or the tray 2 is provided with the slide rail 3111, and the other of the host 1 or the tray 2 is provided with the slide base 3211, and the slide rail 3111 and the slide base 3211 are correspondingly arranged; in practical applications, the user can insert the slide base 3211 into the slide rail 3111 from one end along the length direction of the slide rail 3111, and then push and pull the host 1 relative to the tray 2 along the length direction of the slide rail 3111. The main unit 1 and the tray 2 are connected by a slide block 3211, which is adapted to slide relative to the inner wall of the slide rail 3111 along the length of the slide rail 3111, and realizes a detachable connection between the main unit 1 and the tray 2. Moreover, when the slide block 3211 slides into place relative to the slide rail 3111, the user can also move the main unit 1 relative to the tray 2 around the axis of the slide block 3211. At this time, the slide block 3211 is adapted to rotate around its own axis and cooperate with the inner wall of the slide rail 3111, thereby realizing a rotational connection between the main unit 1 and the tray 2.

[0046] Thus, in certain specific usage scenarios, such as when the wearable device is a smartwatch, and the user wears the smartwatch on their wrist and needs to make or receive calls or take photos, the main unit 1 can be pushed relative to the support plate 2 along the length of the slide rail 3111 until the slide base 3211 disengages from the slide rail 3111. The main unit 1 can then be removed from the wrist for individual use, such as placing it against the ear for voice calls or rotating it to a suitable angle for taking photos. Alternatively, the main unit 1 can be moved relative to the support plate 2 around the axis of the slide base 3211 to rotate it to a suitable tilt angle relative to the support plate 2, thus meeting the viewing angle requirements for video calls and taking photos. In this manner, in addition to normal wear and use, the main unit 1 of the corresponding smart wearable device can also be detached from the tray 2 for separate use, or the tilt angle of the main unit 1 relative to the tray 2 can be changed according to actual needs. This effectively enriches the setting methods of the corresponding smart wearable device, and there is no need to remove the tray 2 from the user's wrist during use, effectively improving the convenience and comfort of using smartwatches and other corresponding smart wearable devices, thereby enhancing the user experience. At the same time, by means of the linear sliding engagement of the slide base 3211 relative to the slide rail 3111 or the rotation engagement around the axis, the detachable installation and rotational setting of the main unit 1 relative to the tray 2 is realized. The connection structure between the main unit 1 and the tray 2 is simple, easy to manufacture and assemble, and low in cost. It also helps to improve the integration of the corresponding smart wearable device, thereby contributing to the development of thinner and lighter smart wearable devices and further optimizing the user experience.

[0047] In one embodiment, based on the above embodiments, specifically referring to... Figures 1 to 6 In this embodiment, the host 1 is generally a rectangular block structure, and the support plate 2 is adapted to the shape of the host 1 and is generally a rectangular plate structure, supporting the host 1 on one side of its thickness direction; refer to Figure 6 The end face of the tray 2 near the main unit 1 is generally planar, with its middle portion recessed along its thickness towards the side opposite to the main unit 1. This recess adapts to the shape of the protrusions on the surface of the main unit 1 when it is against the tray 2, thereby improving the integration of the wearable device and further consolidating its miniaturization trend. It also prevents the main unit 1 from swinging against the surface of the tray 2 during normal wear. In the embodiments of this application, the shapes of the main unit 1 and the tray 2 are not limited. Furthermore, the shapes of the main unit 1 and the tray 2 should not be considered as specific limitations on the scope of protection of this application.

[0048] In addition, refer to Figure 2 and Figure 3 , Figure 5 and Figure 6In this embodiment, the host structure further includes a locking component 6, which is located at one end of the host structure. The locking component 6 includes a first locking member 61 located on the side of the host 1 near the tray 2 and a second locking member 62 located on the side of the tray 2 near the host 1. When the host 1 is against the tray 2, the first locking member 61 and the second locking member 62 are adapted to be detachably locked to lock the host 1 onto the tray 2. In this way, the structural stability of the host structure can be maintained during normal wear.

[0049] Preferably, in this embodiment, the connecting component 3 is located at one end of the length direction of the main unit 1 and the tray 2 to ensure the user's comfort when wearing the corresponding wearable device; in this case, the locking component 6 is preferably located at the end of the main unit 1 opposite to the connecting component 3 in the length direction. (Refer to...) Figures 1 to 3 The connecting component 3 is located on the end face of the tray 2 near the host 1.

[0050] In this embodiment, refer to Figure 1 , Figure 3 and Figure 5 The connecting component 3 includes a first connector 31 and a second connector 32. The first connector 31 is installed at one end of the main unit 1 along its length, and the second connector 32 is installed at the corresponding end of the tray 2 along its length. Specifically, the first connector 31 includes a gripper 311, which has a C-shaped structure and a slide 3111 formed on its concave surface. The gripper 311 is detachably installed on the main unit 1 via a fixing member 4. (Refer to...) Figure 6 The second connecting member 32 includes a slide rod 321 and a support arm 322. The slide rod 321 is arranged axially parallel to the support plate 2. Its shape is adapted to the concave surface of the gripper 311 and is cylindrical. Its radial dimension is adapted to the inner diameter of the gripper 311 and forms a slide seat 3211. The support arm 322 is arranged perpendicular to the support plate 2. One end of the support arm is connected to the support plate 2, and the other end is connected to the slide rod 321 near the outer circumference of the support plate 2.

[0051] Furthermore, in this embodiment, the support arm 322 is connected to the middle of the slide bar 321 in the axial direction; to achieve the rotational connection between the host 1 and the tray 2, the C-shaped opening of the gripper 311 faces the corresponding end in the length direction of the host 1, that is, the orientation of the C-shaped opening of the gripper 311 is perpendicular to the support arm 322, and one end of the locking component 6 is set away from the length direction of the host 1. In addition, a limiting groove 3112 is formed in the middle of the slide rail 3111 along the length direction of the gripper 3111, and the opening of the limiting groove 3112 is connected to the C-shaped opening of the gripper 311, limiting the movement of the gripper. The depth direction of the groove 3112 is perpendicular to the axial direction of the slide rail 3111. When the C-shaped opening of the gripper 311 is kept facing the side of the support plate 2, and the gripper 311 is fully sleeved on the slide rod 321 along the axial direction of the slide rod 321, that is, after the slide block 3211 slides into place relative to the slide rail 3111, the main unit 1 is moved relative to the support plate 2 around the axis of the slide rod 321. The support arm 322 is embedded in the limiting groove 3112, so that the rotational connection of the main unit 1 relative to the support plate 2 can be realized, so that the user can change the pitch angle of the main unit 1 according to the application scenario.

[0052] It should be noted that, in order to enable the host 1 to hover at a selected angle after being flipped relative to the tray 2, a damping structure is provided between the gripper 311 and the slide bar 321 in this embodiment to increase the sliding friction between the gripper 311 and the slide bar 321, thereby achieving a tight fit connection between the gripper 311 and the slide bar 321. In this embodiment, a rubber pad can be fixedly laid on the concave surface of the gripper 311 and / or the outer peripheral surface of the slide bar 321 as a damping structure. This application does not impose specific restrictions on the form of the damping structure, as these are all prior art and will not be described in detail here.

[0053] In this embodiment, refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The extension dimension of the limiting groove 3112 along the length direction of the slide rail 3111 is adapted to the dimension of the support arm 322 in the same direction. Thus, the user can determine whether the main unit 1 and the tray 2 are assembled correctly by observing the engagement state of the support arm 322 relative to the limiting groove 3112. Furthermore, in this embodiment, the limiting groove 3112 is formed on the claw arm of the gripper 311 closest to the tray 2 when the main unit 1 is in the state of being against the tray 2. Of course, in embodiments of this application, the limiting groove 3112 is also suitable to be formed on each claw arm of the gripper 311 to improve the assembly efficiency of the corresponding smart wearable device.

[0054] In addition, in this embodiment, reference is made to Figure 6Preferably, both ends of the slide bar 321 are chamfered to form chamfered bevels 3212, which facilitate the insertion of the slide block 3211 into the slide rail 3111 from one end. Of course, in the embodiments of this application, the chamfered bevels 3212 can also be provided on the concave surface of the gripper 311. In this case, the chamfered bevels 3212 are formed on both end faces of the gripper 311 in the axial direction.

[0055] Reference Figure 5 To further improve the production efficiency of the corresponding smart wearable devices, in this embodiment, the first connector 31 further includes a positioning arm 312, which is connected to the convex surface of the gripper 311. A positioning groove 11 is provided at the corresponding end of the main unit 1 along its length. During assembly, the positioning arm 312 is fitted into the positioning groove 11 according to its shape and size, and then locked to the corresponding part on the main unit 1 by the fixing member 4. In this embodiment, the positioning arm 312 is integrally formed with the gripper 311 and is located on the side of the gripper 311 away from its C-shaped opening. The positioning arm 312 extends its dimension radially away from the gripper 311 along the corresponding position of the gripper 311. Furthermore, the fixing member 4 is set as a fixing bolt 41, the threaded end of which passes through the positioning arm 312 from the inner wall of the C-shaped opening of the gripper 311 and is screwed into the bottom wall of the positioning groove 11 when the gripper 311 is assembled to the main unit 1. Of course, the fixing member 4 can also be set as a magnetic or snap-fit ​​type. In the embodiments of this application, the positioning arm 312 may also be formed at other positions on the convex surface of the gripper 311, as long as it is set in accordance with the setting form of the positioning groove 11; in addition, the positioning arm 312 may also be detachably connected to the gripper 311 through the fixing member 4 or other locking members. This application will not elaborate on these details here. The connection method and setting position of the positioning arm 312 relative to the gripper 311 and the setting form of the fixing member 4 should not be regarded as specific limitations on the protection scope of this application.

[0056] Reference Figure 1 and 2In this embodiment, to improve the aesthetics of the corresponding smart host 1 device, a mounting groove 12 is provided at one end of the host 1 along its length. The mounting groove 12 is located on the side of the host 1 closest to the tray 2 when the host 1 is in the state of being attached to the tray 2, so that a cantilever 13 is formed on the side of the host 1 away from the tray 2. In other words, a cantilever 13 is formed at one end of the host 1 along its length where a gripper 311 is provided. The cantilever 13 is located on the side of the host 1 away from the tray 2 along its thickness, and forms a mounting groove 12 with the corresponding end wall along the length of the host 1. The gripper 311 is detachably mounted on the inner wall of the mounting groove 12, that is, the positioning groove 11 is provided in the mounting groove 12. On the inner wall of the mounting groove 12; at this time, the connecting components 3 are all located in the mounting groove 12. The connecting components 3 are shielded by the cantilever 13, that is, the side wall of the mounting groove 12 away from the tray 2, which is also conducive to extending the service life of the connecting components 3 and avoiding damage caused by frequent bumps during use; in addition, the end face of the free end of the cantilever 13 is generally flat and basically perpendicular to the tray 2. The outer peripheral surface of the slide rod 321 is always roughly flush with the end face of the free end of the cantilever 13, so as to ensure that the main unit 1 can rotate relative to the tray 2 within a range of at least 90° around the axis of the slide rod 321.

[0057] Corresponding to tray 2, in this embodiment, refer to Figure 6 One end of the corresponding connecting component 3 is provided with a connecting groove 21, and the end of the support arm 322 facing away from the slide bar 321 is preferably embedded in the connecting groove 21 and is detachably connected to the tray 2.

[0058] In one embodiment of this application, reference is made to Figure 6 The support arm 322 is configured as a plate-like structure, extending along the width direction of the support plate 2 and parallel to the axial direction of the slide rod 321. Its width direction is perpendicular to the support plate 2. The slide rod 321 is integrally formed on one end of the support arm 322 facing away from the support plate 2 in the width direction. The other end of the support arm 322 in the width direction is embedded in the connecting groove 21 and is detachably and fixedly connected to the support plate 2 through a tight-fitting insertion, snap-fit, or fastener 5. (Refer to...) Figures 1 to 2 In this embodiment, the connecting groove 21 is configured as a rectangular groove structure, and a fastening bolt 51 is provided as a fastener 5 to assemble the support arm 322 onto the tray 2. The fastening bolt 51 is located on the side of the tray 2 away from the connecting groove 21 in the thickness direction, and is configured corresponding to the connecting groove 21. Its threaded end is adapted to penetrate the tray 2 and extend into the connecting groove 21. During assembly, after the end of the support arm 322 away from the slide rod 321 is fully embedded in the connecting groove 21, the fastening bolt 51 is screwed until its threaded end locks into the support arm 322, thereby realizing the detachable fixed connection of the second connector 32 on the tray 2.

[0059] Of course, in another embodiment of this application, one end of the support arm 322 extending into the connecting groove 21 can be rotatably connected to the tray 2. In this case, the connecting groove 21 is preferably a circular groove structure (not shown in the accompanying drawings). The support arm 322 is adapted to the shape and size of the connecting groove 21 and is set as a cylindrical structure. One end of the support arm 322 is integrally formed with the aforementioned sliding rod 321, and the other end is embedded in the connecting groove 21. Rotational connection with the tray 2 is achieved through tight fitting or other means. In practical applications, after adjusting the host 1 relative to the tray 2 to a preset pitch angle, the host 1 can be rotated around the axis of the support arm 322 to adjust the orientation of the host 1, further expanding the viewing angle range of the camera, screen, etc. on the host 1, thereby significantly expanding the applicable range of the corresponding host structure and ensuring a stable user experience.

[0060] In the embodiments of this application, the positions of the first connector 31 and the second connector 32 can also be interchanged. That is, the first connector 31 is installed at one end of the length direction of the tray 2, and the second connector 32 is installed at the corresponding end of the length direction of the host 1. In this case, the C-shaped opening of the gripper 31 needs to be set perpendicular to the tray 2 and away from the side of the tray 2. The limiting groove 3112 is preferably opened on the claw arm of the gripper 31 near the locking component 6. The positioning arm 312 is inserted into the connecting groove 21 and locked by fasteners 5, etc., so that the first connector 31 can be detachably connected to the tray 2. Similarly, the end of the support arm 322 away from the slide bar 321 is embedded in the positioning groove 11, and the second connector 32 is detachably connected to the host 1 by fixing parts 4, etc. This embodiment will not be described in detail.

[0061] The host structure of this application, through the sliding and rotating cooperation of the gripper 311 and the slide bar 321, realizes the convenient separation, assembly, and rotational connection of the host 1 relative to the tray 2. The corresponding connection structure is simple, easy to manufacture, and low in cost. Furthermore, the user can push the host 1 to slide along a straight line or rotate around the axis to meet the corresponding operation requirements in different usage scenarios. The process of use is convenient and comfortable. In addition, the whole machine is small and thin, applicable to a wide range of scenarios, with good comprehensive performance, stable guarantee of user experience, and helps enterprises reduce costs and increase efficiency.

[0062] The technical solution of this application will be further described below, taking the above-described host structure applied to a specific wearable device as an example. In one embodiment, refer to... Figures 1 to 6 A wearable device is provided, including the host structure described in any of the above embodiments. When the host structure is set as a smartwatch, the wearable device also includes a watch strap. Both ends of the tray 2 are provided with connecting ears 22. The two ends of the watch strap are rotatably connected to the tray 2 through the corresponding connecting ears 22 so that the user can wear the corresponding smartwatch on his / her wrist.

[0063] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
