Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, specifically relating to an airbag fixing structure, an airbag assembly, and a wearable device. Background Technology

[0002] With the development of technology and people's increasing attention to health, wearable devices are becoming more and more diverse in function; for example, some high-end smartwatches, smart bracelets and other wearable devices have integrated blood pressure measurement functions.

[0003] Common wearable devices with blood pressure measurement functions typically include a watch body and an air bladder located within the watch body. The air bladder is connected to an internal air supply component, allowing the air bladder to be inflated and fit snugly against the user's wrist. To ensure the air bladder can adapt to different wrist circumferences and improve wearing comfort, the air bladder is usually detachably connected to the watch body using a squeeze-out cover. This allows for the replacement of air bladders of different sizes, ensuring the length of the air bladder can be adapted to different wrist circumferences. Furthermore, when the user does not need to use the blood pressure measurement function, the air bladder can be detached from the watch body to reduce wrist strain and further enhance wearing comfort.

[0004] Currently, the end of the cover plate or the watch body is usually equipped with a locking component. The locking component includes a spring and a locking element that is slidably connected to it. The spring's axial direction is parallel to the sliding direction of the locking element and acts on the locking element, so that the spring can apply an elastic force to the locking element toward the locking position, thereby increasing the locking stability between the cover plate and the watch body. At the same time, when removing the cover plate, a force parallel to the sliding direction can be applied to the locking element to make the locking element overcome the elasticity of the spring and move toward the position where the cover plate and the watch body are released, thereby realizing the removal of the cover plate. However, since the spring's axial direction is parallel to the sliding direction of the locking element, the spring may detach from the cover plate or watch body when installing the locking element and the spring, which increases the assembly difficulty of the locking component and affects its reliability. Utility Model Content

[0005] This application provides an airbag fixing structure to reduce the assembly difficulty of the locking component and improve the reliability of the locking component.

[0006] The technical solution adopted in this application is as follows:

[0007] An airbag fixation structure, comprising:

[0008] A cover plate component for securing the airbag;

[0009] A locking member includes a locking element and an elastic element. The locking element has a locking portion and is rotatably connected to the cover plate member so that the locking element has a locking position in which the locking portion can engage with the watch body and an unlocking position in which the locking portion can disengage from the watch body. The elastic element is capable of torsional deformation, and its two ends are respectively connected to the locking element and the cover plate member so as to apply an elastic force to the locking element to rotate toward the locking position.

[0010] By adopting the above technical solution, when the locking part is released from the watch body, a rotational force is applied to the locking part so that the locking part overcomes the elastic force of the elastic part and rotates. Then, the locking part moves with the locking part and moves to the unlocked position, so as to release the locking part from the watch body.

[0011] Because the locking element is rotatably connected to the cover plate component, it can switch between the locked and unlocked positions by rotating. Furthermore, because the elastic element can undergo torsional deformation, the force that restores this torsional deformation drives the locking element to rotate toward the locked position. Compared to the sliding locking element in existing technologies, this changes the installation direction of the elastic element from parallel to the sliding direction of the locking element to parallel to the rotation axis of the locking element. This reduces the risk of the elastic element easily detaching from the cover plate component during installation, thereby reducing the assembly difficulty and efficiency of the locking element, and improving its reliability to ensure the stability of the airbag fixing structure.

[0012] Furthermore, when applying a force to the locking component toward the unlocking position, the torque between the force application position and the rotation axis of the locking component can be generated by adjusting the force application position of the locking component. This reduces the force required to drive the locking component to the unlocking position, thereby facilitating the separation of the airbag fixing structure from the watch body and making it easier to disassemble the airbag.

[0013] Optionally, the cover plate component is provided with an installation cavity, the locking member and the elastic member are both provided in the installation cavity, the locking part is provided on the side of the locking member, the cover plate component is provided with a passage communicating with the installation cavity, and the locking part can extend out of the installation cavity through the passage.

[0014] By adopting the above technical solution, since both the locking element and the elastic element are located in the mounting cavity, the locking element and the elastic element can be hidden inside the cover plate component, thereby improving the appearance quality of the airbag fixing structure and increasing its stability. Furthermore, since the locking part is located on the side of the locking element, and the cover plate component has a passageway communicating with the mounting cavity, the locking part can extend out of the mounting cavity through the passageway, thereby simplifying the structure of the locking part and simplifying the structural design of the airbag fixing structure, thus achieving the effect of reducing the production cost of the airbag fixing structure.

[0015] Optionally, the cover plate component is provided with an operating hole communicating with the mounting cavity, and the locking member is provided with a pusher extending into the operating hole, and the pusher is spaced apart from the rotation axis of the locking member.

[0016] By adopting the above technical solution, since the locking component is equipped with a pusher that extends into the operating hole, when the locking component is driven toward the unlocking position, force can be applied to the pusher, causing the pusher to move the locking component, thereby achieving the effect of rotating the locking component toward the unlocking position. This facilitates driving the locking component to the unlocking position, thereby reducing the difficulty of driving the locking component to the unlocking position and increasing the difficulty of disassembling the airbag. Furthermore, since the rotation axes of the pusher and the locking component are spaced apart, a torque can be formed between the pusher and the rotation axes of the locking component when the locking component is driven toward the unlocking position. This reduces the force required to apply to the locking component when it is driven toward the unlocking position, further reducing the difficulty of disassembling the airbag.

[0017] Optionally, the cover plate component is provided with a positioning body located in the mounting cavity, and the locking member is sleeved on the outside of the positioning body.

[0018] By adopting the above technical solution, since the locking component is sleeved on the outside of the positioning body, the positioning body can be used to position the locking component. On the one hand, this can increase the connection stability between the locking component and the cover plate component, and on the other hand, it can reduce the assembly difficulty of the locking component, thereby further reducing the assembly difficulty of the locking component.

[0019] Optionally, the elastic element is a torsion spring sleeved on the outside of the positioning body, with one end of the torsion spring engaged with the locking element and the other end of the torsion spring engaged with the cover plate component.

[0020] By adopting the above technical solution, since the elastic element is a torsion spring sleeved on the outside of the positioning body, the stability of the locking element when it is in the locked position is increased, so as to ensure the stability of the snap-fit ​​between the airbag fixing structure and the watch body, thereby increasing the fixing effect of the airbag. On the other hand, the installation difficulty of the elastic element can be reduced, so as to further reduce the installation difficulty of the locking component, and thus further improve the assembly efficiency of the airbag fixing structure.

[0021] Optionally, the cover plate component is provided with a stop body, and when the locking member is in the unlocked position, the locking member and the stop body cooperate to stop.

[0022] By adopting the above technical solution, when the locking component is in the unlocked position, it engages with the stop body, thereby limiting the rotation range of the locking component. This prevents the locking component from scratching the operating hole wall when unlocking, thus ensuring the appearance quality of the airbag fixing structure and improving the user experience. Furthermore, it avoids the possibility of the locking component pressing against the operating hole wall when in the unlocked position, which could cause pressure on the user's fingers, further enhancing the user experience.

[0023] Optionally, the locking member is located at one end of the cover plate member, and the other end of the cover plate member is provided with a locking block that can engage with the watch body.

[0024] By adopting the above technical solution, since the locking component is located at one end of the cover plate component and the other end of the cover plate component is provided with a locking block that can engage with the watch body, when disassembling the airbag, only the locking component located at one end of the cover plate component needs to be operated, thereby reducing the difficulty of disassembling the airbag and improving the efficiency of disassembling the airbag.

[0025] Optionally, the locking block is slidably connected to the cover plate member in a direction close to or away from the locking member, so that the locking block has a snap-fit ​​position that can engage with the watch body and a clearance position that can avoid the watch body. The airbag fixing structure also includes an elastomer connected to the cover plate member and the locking block and used to apply an elastic force to the locking block toward the snap-fit ​​position.

[0026] By adopting the above technical solution, since the locking block slides and connects to the cover plate component along the direction of approaching or moving away from the locking component, when installing the airbag fixing structure, it is only necessary to first place the airbag fixing structure at the position on the watch body where the airbag fixing structure needs to be installed, and then apply pressure to the airbag fixing structure towards the side where the watch body is located. Under the action of this pressure, the locking block overcomes the elastic force of the elastic body and moves towards the avoidance position, thereby causing the cover plate component and the watch body to move relative to each other. After the airbag fixing structure moves to the set position, the locking block moves towards the locking position under the action of the elastic body, so that the locking block and the watch body are locked together, thus completing the installation of the airbag fixing structure. In this process, only pressure needs to be applied to the airbag fixing structure, thereby reducing the difficulty of installing the airbag fixing structure and improving the user experience.

[0027] Optionally, the cover plate component is provided with a receiving cavity and an extension communicating with the receiving cavity, and the locking block is located in the receiving cavity and can extend to the outside of the receiving cavity through the extension.

[0028] By adopting the above technical solution, since the cover plate component is provided with a receiving cavity and an extension opening communicating with the receiving cavity, the locking block is located in the receiving cavity and can extend to the outside of the receiving cavity through the extension opening. Thus, on the one hand, the locking block is hidden inside the cover plate component to improve the appearance quality of the airbag fixing structure. On the other hand, it can also increase the connection stability between the locking block and the cover plate component to ensure the connection stability between the airbag fixing structure and the watch body, thereby ensuring the fixing effect of the airbag fixing structure on the airbag.

[0029] Optionally, the locking block is provided with a limiting body, and the cover plate component is provided with a limiting wall. When the locking block is in the snap-fit ​​position, the limiting body and the limiting wall cooperate to stop it.

[0030] By adopting the above technical solution, when the lock block is in the latching position, the limiting body and the limiting wall stop cooperate, thereby limiting the movement range of the lock block by utilizing the cooperation between the limiting body and the limiting wall, so as to avoid the lock block possibly detaching from the cover plate component, thereby increasing the connection stability between the lock block and the cover plate component.

[0031] Optionally, one of the locking block and the cover plate component is provided with a sliding groove, and the other of the two components is provided with a sliding body that slides in cooperation with the sliding groove.

[0032] By adopting the above technical solution, since one of the locking block and the cover plate components is provided with a sliding groove, and the other of the components is provided with a sliding body that slides in cooperation with the sliding groove, the locking block can be guided by the sliding body and the sliding groove to increase the stability of the locking block during movement. On the other hand, the locking block can be limited by the cooperation between the sliding body and the sliding groove to increase the connection stability between the locking block and the cover plate component.

[0033] Optionally, the cover plate component includes a bottom shell and a cover body disposed on the bottom shell, and a mounting cavity for accommodating the locking member is formed between the bottom shell and the cover body.

[0034] By adopting the above technical solution, when installing the locking component, the cover is first separated from the bottom shell, and then the locking component and the elastic component are installed in the mounting cavity. Then the cover is installed on the bottom shell, which further facilitates the installation of the locking component and improves the installation efficiency of the locking component. At the same time, since the mounting cavity for accommodating the locking component is formed between the bottom shell and the cover, the difficulty of forming the mounting cavity is reduced, thereby reducing the production difficulty of the cover plate component.

[0035] Optionally, the bottom shell is provided with a snap-fit ​​groove at one end of the cover, the cover is provided with a snap-fit ​​arm extending into the snap-fit ​​groove, and the end of the cover away from the snap-fit ​​arm is provided with a fastener that can be detachably connected to the bottom shell.

[0036] By adopting the above technical solution, when installing the cover, the snap-fit ​​arm at one end of the cover is first inserted into the snap-fit ​​groove, and then the fastener is installed. The fastener is used to fix the cover to the bottom shell, thus completing the installation of the cover to the bottom shell. Because the cover is provided with a snap-fit ​​arm that extends into the snap-fit ​​groove, the cooperation between the snap-fit ​​arm and the snap-fit ​​groove can be used to position the cover, thereby facilitating the installation of the fastener and improving the installation efficiency of the cover.

[0037] This application also provides an airbag assembly to ensure the stability of the connection between the airbag and the body.

[0038] An airbag assembly includes an airbag and an airbag fixation structure as described above.

[0039] By adopting the above technical solution, the airbag assembly in this application uses the aforementioned airbag fixing structure, thereby increasing the stability of the elastic element and ensuring the connection stability between the airbag and the body.

[0040] Optionally, the cover plate component includes a bottom shell and a cover body, and the airbag has a vent end located between the bottom shell and the cover body.

[0041] By adopting the above technical solution, since the vent is located between the bottom shell and the cover plate, the airbag can be fixedly connected to the airbag fixing structure by the mutual compression of the bottom shell and the cover plate, thereby increasing the connection stability between the airbag and the airbag fixing structure. At the same time, it can also reduce the number of parts required to install the airbag on the watch body, thereby facilitating the installation of the airbag on the watch body and improving the installation efficiency of the airbag.

[0042] Optionally, the vent end is provided with a connection hole, and one of the bottom shell and the cover is provided with a connector that extends into the connection hole.

[0043] By adopting the above technical solution, since one of the bottom shell and the cover is provided with a connector that extends into the connection hole, on the one hand, the airbag can be positioned by the cooperation between the connector and the connection hole, so as to facilitate the precise installation of the airbag. On the other hand, the airbag can be limited by the cooperation between the connector and the connection hole, so as to further increase the connection stability between the airbag and the airbag fixing structure, and further increase the connection stability between the airbag and the watch body.

[0044] This application also provides a wearable device to ensure the stability of the connection between the airbag and the watch body.

[0045] A wearable device includes a body and an airbag fixing structure or an airbag assembly as described above.

[0046] By adopting the above technical solution, the wearable device in this application uses the above-mentioned airbag fixing structure or airbag fixing component, thereby increasing the stability of the elastic element and thus increasing the connection stability between the airbag and the watch body.

[0047] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0048] 1. The airbag fixing structure in this application includes a cover plate component and a locking component. The cover plate component is used to fix the airbag. The locking component includes a locking element and an elastic element. The locking element has a locking portion and is rotatably connected to the cover plate component so that the locking element has a locking position where the locking portion can engage with the watch body and an unlocking position where the locking portion can disengage from the watch body. The elastic element is capable of torsional deformation, and its two ends are respectively connected to the locking element and the cover plate component to apply an elastic force to the locking element to rotate toward the locking position. Compared to the spring installation method in the prior art, the installation direction of the elastic element in this application is changed. The installation direction of the elastic element is changed from parallel to the sliding direction of the locking element to parallel to the rotation axis of the locking element. This reduces the risk of the elastic element easily detaching from the cover plate component during the installation process, thereby reducing the assembly difficulty of the locking component, improving the assembly efficiency of the locking component, and improving the reliability of the locking component to ensure the stability of the airbag fixing structure for the airbag.

[0049] 2. The cover plate component in this application is provided with an installation cavity, in which the locking element and the elastic element are both located. This allows the locking element and the elastic element to be hidden inside the cover plate component, thereby improving the appearance quality of the airbag fixing structure and increasing its stability. The locking part is located on the side of the locking element, and the cover plate component is provided with a passage communicating with the installation cavity. The locking part can extend out of the installation cavity through the passage, thereby simplifying the structure of the locking part and simplifying the structural design of the airbag fixing structure, thus reducing the production cost of the airbag fixing structure.

[0050] 3. The cover plate component in this application is provided with an operating hole communicating with the mounting cavity, and the locking component is provided with a pusher body extending into the operating hole. When the locking component is driven toward the unlocking position, force can be applied to the pusher body, causing the pusher body to drive the locking component to move, thereby realizing the rotation of the locking component toward the unlocking position. This facilitates driving the locking component to the unlocking position, thereby reducing the difficulty of driving the locking component to the unlocking position and increasing the difficulty of disassembling the airbag. Furthermore, the rotation axes of the pusher body and the locking component are spaced apart, so that when the locking component is driven toward the unlocking position, a torque can be formed between the rotation axes of the pusher body and the locking component. This reduces the force required to apply to the locking component when it is driven toward the unlocking position, thereby further reducing the difficulty of disassembling the airbag.

[0070] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0071] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0072] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0073] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0074] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0075] Reference Figures 1 to 10An airbag fixing structure is disclosed, which includes a cover plate component 1 and a locking component 2. The cover plate component 1 is used to fix the airbag 4. The locking component 2 includes a locking member 21 and an elastic member 22. The locking member 21 has a locking part 211. The locking member 21 is rotatably connected to the cover plate component 1 so that the locking member 21 has a locking position in which the locking part 211 can engage with the watch body and an unlocking position in which the locking part 211 can disengage from the watch body. The elastic member 22 can generate torsional deformation, and its two ends are respectively connected to the locking member 21 and the cover plate component 1 so as to apply an elastic force to the locking member 21 to rotate toward the locking position.

[0076] It is understandable that the watch body is provided with a snap-fit ​​cavity that can accommodate the locking part 211. When the airbag fixing structure is installed on the watch body, the locking part 211 is located in the snap-fit ​​cavity so that the airbag fixing structure and the watch body are snap-fitted together.

[0077] When the locking part 211 is released from the watch body, a rotational force is applied to the locking member 21 so that the locking member 21 overcomes the elastic force of the elastic member 22 and rotates. Then, the locking member 21 moves with the locking member 21 and moves to the unlocked position, so as to release the locking part 211 from the watch body.

[0078] Since the locking member 21 is rotatably connected to the cover plate member 1, the locking member 21 can be switched between the locked and unlocked positions by rotating. Since the elastic member 22 can generate torsional deformation, the elastic force of the elastic member 22 can drive the locking member 21 to rotate toward the locked position. Compared with the sliding method of the locking member 21 in the prior art, this changes the installation direction of the elastic member 22, changing it from parallel to the sliding direction of the locking member 21 to parallel to the rotation axis of the locking member 21. This reduces the risk of the elastic member 22 easily detaching from the cover plate member 1 during the installation process, thereby reducing the assembly difficulty of the locking member 2, improving the assembly efficiency of the locking member 2, and improving the reliability of the locking member 2 to ensure the stability of the airbag fixing structure for the airbag 4.

[0079] Furthermore, when applying a force to the locking member 21 toward the unlocking position, the torque can be generated between the force application position of the locking member 21 and the rotation axis of the locking member 21 by adjusting the force application position of the locking member 21. This reduces the force required to drive the locking member 21 to the unlocking position, thereby facilitating the user to separate the airbag fixing structure from the watch body and making it easier to disassemble the airbag 4.

[0080] This application does not specifically limit the relative positional relationship between the locking member 2 and the cover plate member 1, nor the location of the locking part 211. Preferably, referring to... Figures 4 to 6 The cover plate component 1 is provided with an installation cavity 111, and the locking member 21 and the elastic member 22 are both provided in the installation cavity 111. The locking part 211 is provided on the side of the locking member 21. The cover plate component 1 is provided with a passage 112 communicating with the installation cavity 111, and the locking part 211 can extend out of the installation cavity 111 through the passage 112.

[0081] It is understandable that the locking member 2 is located inside the cover plate member 1.

[0082] Since both the locking element 21 and the elastic element 22 are located in the mounting cavity 111, they can be hidden inside the cover plate component 1, thereby improving the appearance quality of the airbag fixing structure and increasing its stability. Furthermore, since the locking part 211 is located on the side of the locking element 21, and the cover plate component 1 has a passage 112 communicating with the mounting cavity 111, the locking part 211 can extend out of the mounting cavity 111 through the passage 112, thereby simplifying the structure of the locking part 211 and simplifying the structural design of the airbag fixing structure, thus reducing the production cost of the airbag fixing structure.

[0083] This application does not specifically limit the structure of the locking part 211; preferably, refer to... Figure 7 and Figure 8 The locking part 211 is a block-shaped structure located on the side of the locking member 21, and the block-shaped structure is provided with a guide surface 212 that contacts and engages with the watch body. When installing the airbag fixing structure onto the watch body, simply place the airbag fixing structure at the desired location on the watch body, so that the guide surface 212 abuts against the watch body. Then, apply pressure to the airbag fixing structure in the direction of the watch body, causing the locking part 211 to overcome the elastic force of the elastic member 22 under the guidance of the guide surface 212 and move towards the unlocked position. This causes the airbag fixing structure to move relative to the watch body, ultimately moving the airbag fixing structure to the set position. Then, the locking member 21 moves towards the locked position under the action of the elastic member 22, so that the locking part 211 engages with the watch body, completing the installation of the airbag fixing structure and achieving the effect of facilitating the installation of the airbag fixing structure. In other embodiments, the locking part 211 can also be a protrusion or columnar structure located on the side of the locking member 21, or other structures that can engage with the watch body.

[0084] This application does not specifically limit the rotation method of the cover plate component 1. Preferably, refer to Figures 1 to 6The cover plate component 1 is provided with an operation hole 113 communicating with the mounting cavity 111, and the locking component 21 is provided with a pusher body 213 extending into the operation hole 113, and the pusher body 213 and the rotation axis of the locking component 21 are spaced apart.

[0085] It is understandable that by applying a pushing force to the pusher 213, the locking member 21 can be moved from the locked position to the unlocked position.

[0086] It should be noted that the "interval setting of the rotation axis of the push body 213 and the locking member 21" mentioned above means that the push body 213 is not on the rotation axis of the locking member 21.

[0087] Because the locking member 21 is provided with a pusher 213 that extends into the operating hole 113, when the locking member 21 is driven toward the unlocking position, force can be applied to the pusher 213, causing the pusher 213 to drive the locking member 21 to move, thereby making the locking member 21 rotate toward the unlocking position. This facilitates driving the locking member 21 to the unlocking position, thereby reducing the difficulty of driving the locking member 21 to the unlocking position and increasing the difficulty of disassembling the airbag 4. Furthermore, because the rotation axes of the pusher 213 and the locking member 21 are spaced apart, a torque can be formed between the pusher 213 and the rotation axes of the locking member 21 when the locking member 21 is driven toward the unlocking position. This reduces the force required to be applied to the locking member 21 when it is driven toward the unlocking position, thereby further reducing the difficulty of disassembling the airbag 4.

[0088] The better one is to refer to Figure 2 The pusher body 213 protrudes from the end face of the cover plate component 1 away from the mounting cavity 111, so as to facilitate the user to push the pusher body 213.

[0089] This application does not specifically limit the connection method between the pusher body 213 and the locking member 21. Preferably, the pusher body 213 is integrally formed with the locking member 21 to increase the connection stability between the pusher body 213 and the locking member 21, while reducing the number of parts required to assemble the airbag fixing structure, thereby improving the assembly efficiency of the airbag fixing structure. In other embodiments, the pusher body 213 can also be fixedly connected to the locking member 21 by screws or threads.

[0090] In other embodiments, the pusher 213 can be omitted, and the locking member 21 is provided with a rotating shaft passing through the cover plate member 1. The central axis of the rotating shaft is collinear with the rotation axis of the locking member 21. A screwing body is provided at one end of the rotating shaft passing through the cover plate member 1 so that the locking member 21 can be driven to rotate by screwing the screwing body.

[0091] This application does not specify the rotational connection method between the locking member 21 and the cover plate member 1. Preferably, refer to Figures 4 to 6 The cover plate component 1 is provided with a positioning body 114 located in the mounting cavity 111, and the locking member 21 is sleeved on the outside of the positioning body 114.

[0092] Understandably, the locking element 21 is provided with a hole structure into which the positioning body 114 extends.

[0093] Since the locking member 21 is sleeved on the outside of the positioning body 114, the positioning body 114 can be used to position the locking member 21. On the one hand, this can increase the connection stability between the locking member 21 and the cover plate member 1, and on the other hand, it can reduce the assembly difficulty of the locking member 21, so as to further reduce the assembly difficulty of the locking member 2.

[0094] This application does not specifically limit the connection method between the positioning body 114 and the cover plate component 1. Preferably, the positioning body 114 is integrally formed into the cover plate component 1. This increases the connection stability between the positioning body 114 and the cover plate component 1, and reduces the number of parts required for assembly when assembling the airbag fixing structure, thereby improving the assembly efficiency of the airbag fixing structure. In other embodiments, the positioning body 114 can also be connected to the cover plate component 1 by screw fixing or threaded connection.

[0095] This application does not specifically limit the structure of the elastic element 22; preferably, refer to... Figures 5 to 8 The elastic element 22 is a torsion spring sleeved on the outside of the positioning body 114. One end of the torsion spring is engaged with the locking element 21, and the other end of the torsion spring is engaged with the cover plate component 1.

[0096] It is understood that both the locking member 21 and the cover plate member 1 are provided with receiving grooves for accommodating the ends of the torsion spring, and the two ends of the torsion spring are respectively engaged in the receiving grooves on the locking member 21 and the cover plate member 1.

[0097] Since the elastic element 22 is a torsion spring sleeved on the outside of the positioning body 114, it increases the stability of the locking element 21 when it is in the locked position, so as to ensure the stability of the snap-fit ​​between the airbag fixing structure and the watch body, thereby increasing the fixing effect of the airbag 4. On the other hand, it can reduce the installation difficulty of the elastic element 22, so as to further reduce the installation difficulty of the locking element 2, thereby further improving the assembly efficiency of the airbag fixing structure. Furthermore, the positioning body 114 can be used to position the torsion spring, thereby increasing the stability of the torsion spring and facilitating the installation of the torsion spring.

[0098] In other implementation examples, the elastic element 22 may also be a coil spring, with its inner end connected to the positioning body 114 and its outer end connected to the locking element 21, so as to apply an elastic force to the locking element 21 to rotate toward the locked position using the coil spring.

[0099] In other embodiments, the locking member 21 is provided with a pivot that passes through the cover plate member 1, so that the locking member 21 is connected to the cover plate member 1 through the pivot.

[0100] In other embodiments, the locking member 2 and the elastic member 22 may both be located outside the cover plate member 1 to improve the visibility of the airbag fixing structure and improve the user experience for mechanical enthusiasts; or, the locking part 211 is provided at the end of the locking member 21, and the locking part 211 is an L-shaped arm structure.

[0101] In a preferred embodiment, refer to Figure 5 and Figure 6 The cover plate component 1 is provided with a stop body 115. When the locking member 21 is in the unlocked position, the locking member 21 and the stop body 115 cooperate to stop and restrict the rotation range of the locking member 21. This prevents the locking member 21 from scratching the wall of the operating hole 113 when it is unlocked, thus ensuring the appearance quality of the airbag fixing structure and improving the user experience. At the same time, it also prevents the locking member 21 from pressing against the wall of the operating hole 113 when it is in the unlocked position, which could cause pressure on the user's fingers, further improving the user experience.

[0102] This application does not specifically limit the connection method between the stop body 115 and the cover plate component 1. Preferably, the stop body 115 is integrally formed into the cover plate component 1 to increase the connection stability between the stop body 115 and the cover plate component 1. This also reduces the number of parts required for assembly when assembling the airbag fixing structure, thereby improving the assembly efficiency of the airbag fixing structure. In other embodiments, the stop body 115 can also be fixedly connected to the cover plate component 1 by means of screws or other methods.

[0103] This application does not specify the number of locking members 2, which can be any of the following embodiments:

[0104] In the first embodiment, the locking member 2 is provided in two sets, and the two sets of locking members 2 are respectively located at both ends of the cover plate member 1. In this way, on the one hand, the two ends of the cover plate member 1 can be engaged with the watch body, and on the other hand, when the airbag fixing structure is disassembled, only the locking member 2 located at one end of the cover plate member 1 needs to be operated, so as to facilitate the disassembly of the airbag fixing structure.

[0105] Implementation Method Two: In this implementation method, refer to... Figures 1 to 6The locking component 2 is located at one end of the cover plate component 1, and the other end of the cover plate component 1 is provided with a locking block 3 that can engage with the watch body.

[0106] Understandably, the watch body also has a snap-fit ​​cavity corresponding to the locking block 3. After the airbag fixing structure is installed on the watch body, the locking block 3 snaps into its corresponding snap-fit ​​cavity.

[0107] Since the locking member 2 is located at one end of the cover plate member 1, and the other end of the cover plate member 1 is provided with a locking block 3 that can engage with the watch body, when disassembling the airbag 4, only the locking member 2 located at one end of the cover plate member 1 needs to be operated, thereby reducing the difficulty of disassembling the airbag 4 and improving the efficiency of disassembling the airbag 4.

[0108] This application does not specify the connection method between the locking block 3 and the cover plate component 1. Preferably, refer to... Figures 1 to 6 The locking block 3 is slidably connected to the cover plate member 1 in the direction of approaching or moving away from the locking member 2, so that the locking block 3 has a snap-fit ​​position that can engage with the watch body and a clearance position that can avoid the watch body. The airbag fixing structure also includes an elastic body 35, which is connected to the cover plate member 1 and the locking block 3 and is used to apply an elastic force toward the snap-fit ​​position to the locking block 3.

[0109] It is understandable that the locking block 3 has a ramp 31 so that the locking block 3 can automatically move toward the avoidance position under the action of the ramp 31 and the pressure toward the side where the watch body is located.

[0110] Since the locking block 3 is slidably connected to the cover plate component 1 in the direction of approaching or moving away from the locking component 2, when installing the airbag fixing structure, it is only necessary to first place the airbag fixing structure at the position where the airbag fixing structure needs to be installed on the watch body, and then apply pressure to the airbag fixing structure towards the side where the watch body is located, so that the locking block 3 overcomes the elastic force of the elastic body 35 under the action of this pressure and moves towards the avoidance position, thereby causing the cover plate component 1 to move relative to the watch body. After the airbag fixing structure moves to the set position, the locking block 3 moves towards the snap-fit ​​position under the action of the elastic body 35, so that the locking block 3 snaps into the watch body to complete the installation of the airbag fixing structure. In this process, only pressure needs to be applied to the airbag fixing structure, thereby reducing the difficulty of installing the airbag fixing structure and improving the user experience.

[0111] This application does not specifically limit the structure of the elastic body 35. Preferably, the elastic body 35 is a spring to ensure the elastic driving effect of the elastic body 35 on the locking block 3 toward the locking position, and the two ends of the spring respectively abut against the locking block 3 and the bottom shell 11. In other embodiments, the elastic body 35 can also be an elastic sheet, an elastic post, or other structures that can apply elastic force to the locking block 3.

[0112] The better one is to refer to Figure 9 The locking block 3 is provided with a guide post 32 at one end near the locking member 2. The elastic body 35 is sleeved on the outside of the guide post 32. On the one hand, the guide post 32 can limit the elastic body 35 to increase the stability of the elastic body 35. On the other hand, the guide post 32 can guide the deformation of the elastic body 35 to increase the stability of the elastic body 35 when it deforms.

[0113] This application does not specifically limit the relative position of the locking block 3 and the cover plate component 1. Preferably, refer to Figure 6 The cover plate component 1 is provided with a receiving cavity 116 and an extension 117 communicating with the receiving cavity 116. The locking block 3 is located in the receiving cavity 116 and can extend to the outside of the receiving cavity 116 through the extension 117.

[0114] It is understandable that the elastic body 35 and the locking block 3 are both located inside the locking member 2.

[0115] Since the cover plate component 1 is provided with a receiving cavity 116 and an extension 117 communicating with the receiving cavity 116, the locking block 3 is located in the receiving cavity 116 and can extend to the outside of the receiving cavity 116 through the extension 117. Thus, on the one hand, the locking block 3 is hidden inside the cover plate component 1 to improve the appearance quality of the airbag fixing structure. On the other hand, it can also increase the connection stability between the locking block 3 and the cover plate component 1 to ensure the connection stability between the airbag fixing structure and the watch body, thereby ensuring the fixing effect of the airbag fixing structure on the airbag 4.

[0116] In other implementation examples, the locking block 3 can also be located outside the cover plate member 1 so that the user can directly see the locking block 3, thereby improving the user experience for mechanical enthusiasts.

[0117] In a preferred embodiment, refer to Figure 5 and Figure 6 The locking block 3 is provided with a limiting body 33, and the cover plate component 1 is provided with a limiting wall 118. When the locking block 3 is in the snap-fit ​​position, the limiting body 33 and the limiting wall 118 stop and cooperate, thereby limiting the movement range of the locking block 3 by utilizing the stop cooperation between the limiting body 33 and the limiting wall 118, so as to avoid the situation where the locking block 3 may detach from the cover plate component 1, thereby increasing the connection stability between the locking block 3 and the cover plate component 1.

[0118] This application does not specifically limit the structure of the limiting body 33; preferably, refer to... Figure 5 The limiting body 33 is formed by a screw threaded to the locking block 3, which reduces the difficulty of forming the limiting body 33 and also facilitates the installation of the locking block 3. In other embodiments, the limiting body 33 may also be formed as a columnar structure passing through the locking block 3, or as a block structure integrally formed on the locking block 3.

[0119] This application does not specify the formation method of the limiting wall 118; preferably, refer to... Figure 6 The cover plate member 1 is provided with a limiting groove, and at least a portion of the limiting body 33 extends into the limiting groove. When the limiting body 33 moves with the locking block 3, the limiting body 33 can move within the limiting groove. When the locking block 3 moves to the engaging position, the limiting body 33 abuts against the side wall of the limiting groove away from the locking member 2, so that the groove wall of the limiting groove away from the locking member 2 forms a limiting wall 118. In other embodiments, the cover plate member 1 is provided with ribs, and the ribs facing the wall of the locking member 2 form the limiting wall 118.

[0120] In a preferred embodiment, refer to Figure 4 , Figure 5 , Figure 6 and Figure 9 One of the locking block 3 and the cover plate component 1 is provided with a sliding groove 119, and the other of the two is provided with a sliding body 34 that slides in cooperation with the sliding groove 119.

[0121] It is understandable that the extension direction of the slide 119 is set parallel to the sliding direction of the locking block 3.

[0122] Since one of the locking block 3 and the cover plate component 1 is provided with a sliding groove 119, and the other is provided with a sliding body 34 that slides in cooperation with the sliding groove 119, the sliding cooperation between the sliding body 34 and the sliding groove 119 can be used to guide the locking block 3, thereby increasing the stability of the locking block 3 during movement. On the other hand, the cooperation between the sliding body 34 and the sliding groove 119 can also be used to limit the locking block 3, thereby increasing the connection stability between the locking block 3 and the cover plate component 1.

[0123] The better one is to refer to Figure 6 and Figure 9 The sliding groove 119 is provided on the cover plate component 1, and the sliding body 34 is integrally formed on the locking block 3 so as to increase the structural strength of the locking block 3 through the sliding body 34, so as to ensure the connection stability between the airbag fixing structure and the surface body.

[0124] This application does not specifically limit the location and shape of the slider 34. Preferably, refer to Figure 9 The sliding body 34 is provided on both opposite sides of the locking block 3, that is, there are two sliding bodies 34, and the two sliding bodies 34 are respectively located on opposite sides of the locking block 3. The sliding groove 119 is provided with two sliding bodies 34 to increase the force balance of the locking block 3. At the same time, the cross section of the sliding body 34 perpendicular to its own length direction is square to reduce the manufacturing difficulty of the locking block 3. In other embodiments, the sliding block can also be provided on the side of the locking block 3 facing the operating hole 113, and the cross section of the locking block 3 perpendicular to its own length direction is "T" shaped.

[0125] In other embodiments, the locking block 3 can also be fixedly connected to the cover plate member 1, for example, the locking block 3 is integrally formed on the end of the cover plate member 1.

[0126] This application does not specifically limit the formation of the mounting cavity 111 and the receiving cavity 116. Preferably, refer to Figure 3 and Figure 4 The cover plate component 1 includes a bottom shell 11 and a cover body 12 disposed on the bottom shell 11. An installation cavity 111 for accommodating the locking member 21 is formed between the bottom shell 11 and the cover body 12.

[0127] It is understandable that a receiving cavity 116 is also formed between the cover 12 and the bottom shell 11, and the positioning body 114, the stop body 115, the operating hole 113, the limiting wall 118 and the sliding groove 119 are all provided on the bottom shell 11.

[0128] When installing the locking member 2, the cover 12 is first separated from the bottom shell 11, and then the locking member 21 and the elastic member 22 are installed in the mounting cavity 111. Then the cover 12 is installed on the bottom shell 11 to further facilitate the installation of the locking member 2, thereby further improving the installation efficiency of the locking member 2. At the same time, since the mounting cavity 111 for accommodating the locking member 21 is formed between the bottom shell 11 and the cover 12, the difficulty of forming the mounting cavity 111 is reduced, thereby reducing the production difficulty of the cover member 1.

[0129] This application does not specifically limit the materials used to manufacture the bottom shell 11 and the cover 12. Preferably, the bottom shell 11 is made of plastic to improve the comfort of the airbag fixation structure when in contact with the skin, while reducing the manufacturing cost of the airbag fixation structure. The cover 12 is made of iron to ensure the structural strength of the cover 12. In other embodiments, the bottom shell 11 may also be made of metal, such as iron or aluminum; the cover 12 may also be made of other metal, such as aluminum, or the cover 12 may be made of plastic.

[0130] This application does not specify the connection method between the cover 12 and the bottom shell 11. Preferably, refer to... Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10 The bottom shell 11 is provided with a snap-fit ​​groove 13 located at one end of the cover 12. The cover 12 is provided with a snap-fit ​​arm 121 extending into the snap-fit ​​groove 13, and the end of the cover 12 away from the snap-fit ​​arm 121 is provided with a fastener 122 that can be detachably connected to the bottom shell 11.

[0131] When installing the cover 12, first insert the snap-fit ​​arm 121 at one end of the cover 12 into the snap-fit ​​groove 13, and then install the fastener 122 so as to fix the cover 12 to the bottom shell 11, thereby completing the installation of the cover 12 to the bottom shell 11.

[0132] Since the cover 12 is provided with a snap-fit ​​arm 121 that extends into the snap-fit ​​groove 13, the cover 12 can be positioned by the cooperation of the snap-fit ​​arm 121 and the snap-fit ​​groove 13, so as to facilitate the installation of the fastener 122 and thus improve the installation efficiency of the cover 12.

[0133] This application does not specifically limit the structure of the fastener 122. Preferably, the fastener 122 is a screw that passes through the cover 12, and the fastener 122 can be threaded through the bottom shell 11. This can increase the connection stability between the cover 12 and the bottom shell 11, and also facilitate the disassembly and assembly of the cover 12. In other embodiments, the fastener 122 can also be a snap-fit ​​post that can engage with the cover 12 component.

[0134] Preferably, the snap-fit ​​arm 121 is bent toward the side where the bottom shell 11 is located, and the cover 12 is provided with a recessed area for accommodating the fastener 122, so that after the snap-fit ​​arm 121 is installed on the bottom shell 11, the snap-fit ​​arm 121 and the fastener 122 do not protrude from the end face of the cover 12 away from the bottom shell 11, so as to reduce the gap between the airbag fixing structure and the watch body, thereby ensuring the fixing effect of the airbag fixing structure on the airbag 4.

[0135] In other embodiments, the design of the snap-fit ​​arm 121 can be omitted, and fasteners 122 can be provided at both ends of the cover 12.

[0136] In other embodiments, the cover plate component 1 may also be an integral structure, and the mounting cavity 111 and the receiving cavity 116 are both formed by holes reserved inside the cover plate component 1.

[0137] Reference Figures 11 to 16 This application also discloses an airbag assembly, which includes an airbag 4 and an airbag fixing structure as described above.

[0138] Because the airbag assembly in this application adopts the above-mentioned airbag fixing structure, the stability of the elastic element 22 is increased, thereby ensuring the connection stability between the airbag 4 and the body.

[0139] This application does not specify the method of fixing the airbag 4 to the airbag fixing structure; preferably, refer to... Figure 12 , Figure 14 and Figure 15The cover plate component 1 includes a bottom shell 11 and a cover body 12. The airbag 4 has a vent end located between the bottom shell 11 and the cover body 12. The airbag 4 can be fixedly connected to the airbag fixing structure by the mutual compression of the bottom shell 11 and the cover body 12, thereby increasing the connection stability between the airbag 4 and the airbag fixing structure. At the same time, it can also reduce the number of parts required to install the airbag 4 on the watch body, thereby facilitating the installation of the airbag 4 on the watch body and improving the installation efficiency of the airbag 4.

[0140] Preferably, the vent end is provided with a connecting hole for connecting the air supply component of the instrument body, and the cover plate is provided with a through hole corresponding to the connecting hole, so as to enable the airbag 4 to connect with the air supply component of the instrument body.

[0141] Furthermore, refer to Figure 14 and Figure 16 The vent end is provided with a connection hole 41. One of the bottom shell 11 and the cover 12 is provided with a connector 131 that extends into the connection hole 41. On the one hand, the cooperation between the connector 131 and the connection hole 41 can be used to position the airbag 4, so as to facilitate the precise installation of the airbag 4. On the other hand, the cooperation between the connector 131 and the connection hole 41 can also be used to limit the airbag 4, so as to further increase the connection stability between the airbag 4 and the airbag fixing structure, and further increase the connection stability between the airbag 4 and the surface.

[0142] Preferably, the connector 131 is located on the bottom shell 11 to further facilitate the installation of the airbag 4.

[0143] This application does not specifically limit the connection method between the connector 131 and the bottom shell 11. Preferably, the connector 131 is integrally formed into the bottom shell 11 to increase the connection stability between the connector 131 and the bottom shell 11. This also reduces the number of parts required for assembly when assembling the airbag assembly, thereby improving the assembly efficiency of the airbag assembly. In other embodiments, the connector 131 can also be connected to the bottom shell 11 by screw fixing or threaded connection.

[0144] In other embodiments, the vent is located on the side of the cover 12 away from the bottom shell 11, that is, the vent is located outside the cover plate member 1, so as to fix the airbag 4 by means of the mutual compression between the airbag fixing structure and the cover body.

[0145] This application also discloses a wearable device, including a watch body and an airbag fixing structure or an airbag assembly as described above.

[0146] Understandably, the instrument body has an internal air supply component that can connect and communicate with the airbag 4, and the instrument body has a snap-fit ​​cavity that can engage with the airbag fixing structure.

[0147] Because the wearable device in this application uses the above-mentioned airbag fixing structure or the above-mentioned airbag 4 fixing component, the stability of the elastic element 22 is increased, thereby increasing the connection stability between the airbag 4 and the watch body.

[0148] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0149] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
