Abstract
Description
Technical Field
[0001] This application relates to the field of consumer electronics, specifically to a meter and a wearable device. Background Technology
[0002] In related technologies, wearable devices such as smartwatches have been gradually applied. To facilitate user operation, these wearable devices usually have a rotating crown structure, allowing users to perform operations such as adjusting the time by rotating the crown. A typical crown structure can be divided into a rotating crown and a stem. Current crown structures have many parts, are complex to assemble, and are difficult and costly to repair when malfunctions occur. Summary of the Invention
[0003] The purpose of this application is to provide a watch head and a wearable device to at least partially improve the above-mentioned technical problems.
[0004] In a first aspect, embodiments of this application provide a watch head, including a housing and a crown assembly. The housing includes a first tube and a second tube. The first tube has a first through hole, and the second tube has a second through hole. The first tube and the second tube are connected, and the first through hole and the second through hole communicate with each other. The crown assembly includes a knob and a rotating rod. The rotating rod passes through the first through hole and the second through hole and can rotate about the axis of the first through hole. The knob includes a top plate and a side plate. One end of the rotating rod extends out of the housing and is connected to the top plate. The side plate is connected to the edge of the top plate and extends toward one side of the housing. There is a gap between the side plate and the rotating rod. The second tube is at least partially embedded in the gap and is opposite to the side plate.
[0005] Secondly, embodiments of this application also provide the aforementioned wearable device, including the aforementioned watch head.
[0006] The watch head and wearable device provided in this application embodiment have a first tube and a second tube connected to form a first through hole and a second through hole for installing a crown assembly. The crown assembly's rotating rod can be rotatably disposed within the first and second through holes. The entire crown assembly installation structure has fewer parts. At the same time, the second tube is embedded in the gap between the side plate and the rotating rod. The side plate can shield the rotating rod and the second tube, so that when the crown assembly is installed, the knob can directly shield the second tube without the need for additional parts to cover the second through hole or the second tube. This results in better overall appearance consistency and better sealing effect.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0020] Currently, in related technologies, the crown components of wearable devices such as smartwatches require the installation of a crown tube. These crown tubes have complex structures and require a separate structure to fix them within the mid-frame of the smartwatch. The large number of required parts leads to complex assembly and repair processes and high costs.
[0021] Based on this, the inventors of this application have proposed various embodiments of the watch head and wearable device to improve the aforementioned technical problems. The embodiments of this application are described in detail below with reference to the accompanying drawings.
[0022] Example like Figure 1 As shown, this embodiment provides a wearable device 10, which can be, but is not limited to, electronic devices such as wristbands, legbands, anklebands, smartwatches, wireless headphones, and head-mounted devices. The wearable device 10 in this embodiment is described using a smartwatch as an example.
[0023] The wearable device 10 includes a watch face 100 and a wearable part 200. The watch face 100 can be used to install human-computer interaction devices such as a display screen. The wearable part 200 is connected to the watch face 100 and is mainly used for users to wear. It is understood that the wearable part 200 can be configured in different forms depending on the wearing position. For example, the wearable part 200 can be configured as a watch strap suitable for wearing on the wrist, thigh, arm, etc., or it can be configured as a headband suitable for wearing on the head, etc., and there is no limitation here. In this embodiment, the watch face 100 is the watch dial, and the wearable part 200 is the watch strap.
[0024] Please see Figure 2 In this embodiment, the meter header 100 includes a middle frame 110 and a cover plate 120. The cover plate 120 is assembled to the middle frame 110 to form a content cavity. Various components can be installed in the content cavity, such as a motherboard 500. This embodiment does not limit the scope of the components.
[0025] The surface of the cover plate 120 is adapted to conform to the user's skin. Taking a smartwatch as an example, the surface of the cover plate 120 can be set to a smooth surface, providing a better tactile experience when worn. In some embodiments, please refer again... Figure 1The meter head 100 may also include a display screen 400, which can be mounted on the middle frame 110 to form a fixed structure. The display screen 400 can be used for human-computer interaction with the user. In some embodiments, the display screen 400 can be a touch screen, and in other embodiments, the display screen 400 can be a flexible screen, etc. This embodiment does not limit this. In other embodiments, the display screen 400 may not be provided. In this case, the second side of the mounting plate 111 can be provided as a mechanical dial structure.
[0026] Please refer to it again. Figure 1 The middle frame 110 has a first axis X and a second axis Y that are perpendicular to each other. The two ends of the middle frame 110 along the first axis X are used to connect to the wearable part 200. That is, the wearable part 200 is arranged along the first axis X of the middle frame 110 and is connected and fixed to the middle frame 110. It can be understood that the wearable part 200 can be fixed to the middle frame 110 by a fixed connection or a detachable connection; this embodiment does not limit this. The wearable part 200 can be made of materials such as leather, plastic, silicone, or metal; this embodiment does not limit this either.
[0027] In this embodiment, please refer to the following: Figure 2 and Figure 3 The middle frame 110 has a mounting hole 112, the axis of which is approximately along the second axis Y, and the mounting hole 112 penetrates the middle frame 110. The mounting hole 112 connects the inner cavity 101 and the outside. Specifically, the middle frame 110 includes a side frame 111, which has an inner surface 113 and an outer surface 114 facing away from each other. The mounting hole 112 is formed in the side frame 111 and penetrates the inner surface 113 and the outer surface 114.
[0028] Please refer to the following: Figure 3 and Figure 4 The housing 100 further includes a first tube 130 and a second tube 140, which are disposed within the mounting hole 112.
[0029] See Figure 5 The first tube 130 has a first through hole 134, and the second tube 140 has a second through hole 141. The first tube 130 and the second tube 140 are connected, and the first through hole 134 and the second through hole 141 are connected. The connected first through hole 134 and the second through hole 141 also connect to the outside and the inner cavity 101. In some embodiments, the first through hole 134 and the second through hole 141 may be coaxially arranged.
[0030] In this embodiment, the first tube 130 and the second tube 140 are fixed by a threaded connection. Specifically, the first tube 130 is provided with an external thread, and the second tube 140 is provided with an internal thread that mates with the external thread. The first tube 130 is disposed within the mounting hole 112 and is located at the end of the mounting hole 112 near the inner cavity 101, that is, the end adjacent to the inner surface 113. The second tube 140 is disposed within the mounting hole 112 and is located at the end of the mounting hole 112 away from the inner cavity 101, that is, the end adjacent to the outer surface 114. In this embodiment, the second tube 140 is located outside the middle frame 110 and is sleeved over the first tube 130. During assembly, the components inside the middle frame 110 can be assembled first, and then the second shell 140 can be assembled from the outside of the middle frame 110. Since the second shell 140 is sleeved over the first shell 130, the assembly process is more convenient.
[0031] Specifically, the first tube body 130 includes a threaded section 131 and a mounting section 132. The mounting section 132 is connected to the threaded section 131. The threaded section 131 is provided with external threads that mate with the second tube body 140. The mounting section 132 passes through the mounting hole 112, and the length of the mounting section 132 may be slightly greater than the thickness of the side frame 111. The first through hole 134 passes through both the mounting section 132 and the threaded section 131. The outer wall of the threaded section 131 is provided with external threads that mate with the second tube body 140.
[0032] In this embodiment, in order to improve the connection stability between the first tube body 130 and the second tube body 140, the first tube body 130 is also provided with a first boss 135. The first boss 135 is located at the end of the mounting section 132 away from the threaded section 131. The first boss 135 abuts against the inner surface 113. The diameter of the second tube body 140 is larger than the diameter of the first tube body 130, and the second tube body 140 is threaded around the first tube body 130 and abuts against the outer surface 114. This is equivalent to the first tube body 130 and the second tube body 140 being threaded together, and the side frame 111 is clamped in the middle. This arrangement does not require other components to fix the first tube body 130 and the second tube body 140, and can form a good stability effect, which can prevent the first tube body 130 and the second tube body 140 from separating from each other or from the mounting hole 112.
[0033] It is understood that in some other embodiments, the first tube 130 and the second tube 140 may also be connected in other ways, such as by snap-fit.
[0034] In a preferred embodiment, both the first tube 130 and the second tube 140 can be made of metal, which has higher structural strength and is easier to process and assemble. Of course, it is understood that in other embodiments, the first tube 130 and the second tube 140 may also be made of other materials, such as plastic.
[0035] In this embodiment, please continue to refer to Figure 4 The housing 100 may also include a decorative element 180, which is attached to the outer surface 114. The decorative element 180 may be made of metal, especially a material with a metallic luster. The decorative element 180 may also be made of other colored materials, such as plastic, leather, etc. This embodiment does not limit this.
[0036] When the decorative element 180 is disposed on the outer surface 114, it can form a ring around the middle frame 110 or be disposed in an intermittent form; this embodiment does not limit this. When the decorative element 180 is disposed on the outer surface 114, it can be disposed only on one side of the mounting hole 112 along the thickness direction of the middle frame 110, or it can be disposed on both opposite sides of the mounting hole 112 along the thickness direction of the middle frame 110. In some embodiments, the decorative element 180 may have an opening at the position corresponding to the mounting hole 112 for the crown assembly 300 to be assembled.
[0037] In this embodiment, to further improve the installation stability of the first pipe body 130 and the second pipe body 140, please refer to the following documentation. Figure 4 and Figure 5 The second tube body 140 is provided with a second boss 142, which abuts against the decorative element 180. Specifically, the decorative element 180 is provided with a recess, and the second boss 142 abuts against the recess. This arrangement allows the second tube body 140 to be simultaneously constrained by the side frame 111 and the decorative element 180, further improving installation stability.
[0038] To improve the sealing performance of the first tube 130 and the second tube 140 after installation, in one embodiment, the meter head 100 further includes a first sealing ring 160. The first sealing ring 160 is disposed between the first tube 130 and the side frame 111 and abuts against both the first tube 130 and the side frame 111. The first sealing ring 160 can be made of an elastic material, such as silicone or rubber. In this embodiment, there is one first sealing ring 160, which is located approximately in the middle of the first tube 130. This prevents external dust, moisture, etc., from entering the inner cavity 101 through the gap between the first tube 130 and the side frame 111.
[0039] For easier setup of the first sealing ring 160, please refer again. Figure 5 The outer wall of the first tube 130 is provided with a first slot 136. The first sealing ring 160 abuts against the side frame 111 and is at least partially embedded in the first slot 136. By providing the first slot 136, the position of the first sealing ring 160 can be fixed, preventing the first sealing ring 160 from sliding along the axial direction of the first tube 130, thus achieving a better sealing effect. At the same time, after the first sealing ring 160 is embedded in the first slot 136, the sealing effect between the first sealing ring 160 and the first tube 130 can be further improved. In other embodiments, the first slot 136 may also be provided on the side frame 111; this embodiment does not limit this.
[0040] In some other embodiments, there may be multiple first sealing rings 160, in which case the multiple first sealing rings 160 may be set at intervals of 323. This embodiment does not limit this.
[0041] In another implementation, see Figure 6 The meter head 100 includes two first sealing rings 160. One first sealing ring 160 is disposed between the first boss 135 and the inner surface 113, that is, it abuts against the first boss 135 and the inner surface 113 of the side frame 111. The other first sealing ring 160 is disposed between the first tube body 130 and the side frame 111 and abuts against the first boss 135, that is, it abuts against the first tube body 130 and the side frame 111, and is limited by the second boss 142. In this embodiment, the interval 323 between the two first sealing rings 160 is the largest, and the sealing effect between the first tube body 130 and the middle frame 110 is better. To better secure the first sealing ring 160, a first slot 136 is provided on the outer wall of the first tube body 130. The first slot 136 is located adjacent to the second protrusion 142. The first sealing ring 160, which abuts against the second protrusion 142, abuts against the side frame 111 and is at least partially embedded in the first slot 136. By providing the first slot 136, the position of the first sealing ring 160 can be fixed, preventing the first sealing ring 160 from sliding along the axial direction of the first tube body 130, thus achieving a better sealing effect. In some other embodiments, the first sealing ring 160 located between the first protrusion 135 and the inner surface 113 can also be fixed with a groove-like structure; this embodiment does not limit this.
[0042] Please refer to the following: Figure 2 and Figure 7The watch head 100 also includes a crown assembly 300, which includes a knob 320 and a rotating rod 310. The rotating rod 310 passes through the first through hole 134 and the second through hole 141 and can rotate about the axis of the first through hole 134. The rotating rod 310 can also extend into the inner cavity 101. The knob 320 includes a top plate 321 and a side plate 322. One end of the rotating rod 310 extends out of the housing 100 and is connected to the top plate 321. The side plate 322 is connected to the edge of the top plate 321 and extends toward one side of the housing 100. There is a gap 323 between the side plate 322 and the rotating rod 310. The knob 320 can be operated by the user to rotate the entire crown assembly 300.
[0043] Please refer to it again. Figure 4 The second tube 140 is at least partially embedded in the interval 323 and faces the side plate 322. That is, the outer wall of the second tube 140 is directly opposite the inner wall of the side plate 322. This arrangement allows the side plate 322 to directly shield the second tube 140, preventing external dust from entering the second through hole 141 and improving the overall appearance of the meter. The depth to which the second tube 140 is embedded in the interval 323 can be adjusted as needed. For example, in some embodiments, the depth of the second tube 140 embedded in the interval 323 may not exceed 1 / 3 of the depth of the interval 323. This ensures that the second tube 140 does not interfere with the user's rotation of the knob 320 and avoids obstructing the knob 320 when the user presses it. Of course, in other embodiments, the depth of the second tube 140 embedded in the interval 323 can be other values, which are not limited in this embodiment.
[0044] In this embodiment, after the crown assembly 300 is assembled into the first through hole 134 and the second through hole 141, it can not only rotate around the axis of the first through hole 134, but also slide along the axis of the first through hole 134 (that is, the second axis Y direction). In other words, the user can control the rotary rod 310 to slide along the axis of the first through hole 134 by pressing the knob part 320. In this embodiment, since the second tube 140 is embedded in the gap 323 between the side plate 322 and the rotary rod 310, when the rotary rod 310 slides along the axis of the first through hole 134, the second tube 140 can guide the sliding of the rotary rod 310 to a certain extent, making the sliding of the rotary rod 310 smoother. Further, please refer again... Figure 2In this embodiment, the meter head 100 may also include a pressing component 510. The pressing component 510 is disposed in the inner cavity 101 and is disposed corresponding to the rotary rod 310. When the user presses the knob part 320, the rotary rod 310 can be driven to slide along the axial direction of the first through hole 134. During the sliding process, the pressing component 510 can be triggered to execute the corresponding function.
[0045] In some embodiments, the pressing component 510 can be a contact structure, meaning that the rotary lever 310 needs to make direct hard contact with the pressing component 510 to trigger it. In other embodiments, the pressing component 510 can be triggered by detecting the position of the rotary lever 310. In this case, the pressing component 510 can be a non-contact structure, meaning that the rotary lever 310 does not need to make direct contact with the pressing component 510 to trigger it.
[0046] In some embodiments, the meter head 100 may further include a light sensor 520. The light sensor 520 is disposed on the main board 500 within the internal cavity 101 and can be used to detect the position information of the rotating rod 310. During detection, the light sensor 520 emits detection light and receives the reflected detection light, thereby determining the position information of the object reflecting the detection light. In this embodiment, the light emission axis of the light sensor 520 is approximately perpendicular to the axis of the rotating rod 310. In other embodiments, the light sensor 520 may be disposed in other locations; this embodiment does not limit this.
[0047] The meter head 100 may also include a control unit (not shown in the figure), which may be electrically connected to the pressing component 510 and the light sensor 520 to obtain the information collected by the pressing component 510 and the light sensor 520, and correspondingly control other components of the meter head 100 to execute corresponding instructions.
[0048] The control unit may include a processor and a memory, which are electrically connected. The processor may include one or more processing cores. The processor connects various parts within the entire meter head using various interfaces and lines, and performs various functions and processes data of the wearable device 10 by running or executing instructions, programs, code sets, or instruction sets stored in the memory, and by calling data stored in the memory. Optionally, the processor may be implemented using at least one hardware form of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), or Programmable Logic Array (PLA). The processor may integrate one or a combination of several of the following: Central Processing Unit (CPU), Graphics Processing Unit (GPU), and modem. The CPU primarily handles the operating system, user interface, and applications; the GPU is responsible for rendering and drawing the displayed content; and the modem handles wireless communication. It is understood that the modem may also not be integrated into the processor and may be implemented separately using a communication chip.
[0049] The memory can store the corresponding control instructions, and the processor can call the control instructions stored in the memory and generate the corresponding control signals. The processor and memory of the control unit can be integrated onto the motherboard 500.
[0050] To prevent the rotating rod 310 from coming out of the first through hole 134 and the second through hole 141, in this embodiment, please refer again... Figure 4 The watch head 100 also includes a locking mechanism 191, which is used to prevent the crown assembly 300 from disengaging from the first through hole 134 and the second through hole 141. Specifically, in a more concrete embodiment, the locking mechanism 191 includes a retaining spring 190. The rotating rod 310 is provided with a retaining spring groove 312, and the retaining spring 190 is disposed within the retaining spring groove 312. The retaining spring 190 abuts against the end face of the first tube 130 away from the second tube 140, thus the rotating rod 310 is restricted by the retaining spring 190 and cannot completely disengage from the first through hole 134 and the second through hole 141. In other embodiments, the locking mechanism may also take other forms, such as a slide rail, etc., which is not limited in this embodiment.
[0051] After the crown assembly 300 is inserted into the first through hole 134 and the second through hole 141, in order to improve the sealing between the rotor 310 and the first tube 130, the watch head 100 may further include a second sealing ring 170, which is disposed between the rotor 310 and the first tube 130. The second sealing ring 170 may be made of an elastic material, such as silicone or rubber. In this embodiment, there is one second sealing ring 170, which is arranged approximately in the middle of the first tube 130. This prevents external dust, moisture, etc., from entering the inner cavity 101 through the gap between the first tube 130 and the rotor 310.
[0052] To facilitate the installation of the second sealing ring 170, a second groove 311 is provided on the outer wall of the rotating rod 310. The second sealing ring 170 abuts against the first tube body 130 and is at least partially embedded in the second groove 311. By providing the second groove 311, the position of the second sealing ring 170 can be fixed, preventing the second sealing ring 170 from sliding along the axial direction of the first tube body 130, thus achieving a better sealing effect. Simultaneously, after the second sealing ring 170 is embedded in the second groove 311, the sealing effect between the second sealing ring 170 and the second tube body 140 can be further improved. In other embodiments, the second groove 311 can also be provided on the inner wall of the first tube body 130; this embodiment does not limit this.
[0053] The wearable device 10 provided in this embodiment has a first tube 130 and a second tube 140 connected to form a first through hole 134 and a second through hole 141 for mounting a crown assembly 300. The rotating rod 310 of the crown assembly 300 can be rotatably disposed within the first through hole 134 and the second through hole 141. The entire mounting structure of the crown assembly 300 has fewer parts. At the same time, the second tube 140 is embedded in the gap 323 between the side plate 322 and the rotating rod 310. The side plate 322 can shield the rotating rod 310 and the second tube 140, so that when the crown assembly 300 is installed, the knob part 320 can directly shield the second tube 140 without the need for additional parts to cover the second through hole 141 or the second tube 140. This results in better overall appearance consistency and better sealing effect.
[0054] In another implementation, see Figure 8The first tube body 130 includes a threaded section 131, a mounting section 132, and an extension section 133. The mounting section 132 connects the threaded section 131 and the extension section 133. The threaded section 131 has an external thread that mates with the second tube body 140. The first boss 135 is located at the connection between the mounting section 132 and the extension section 133, meaning the extension section 133 can extend into the inner cavity 101. The advantage of this arrangement is that by increasing the length of the first tube body 130, the structural strength of the first tube body 130 can be improved. Furthermore, due to the increased length of the first tube body 130, it is less prone to shaking during the assembly and operation of the crown assembly 300. The length of the extension section 133 can, for example, be approximately the same as that of the mounting section 132; this embodiment does not limit this.
[0055] like Figure 6 As shown, at this time, the retaining ring 190 of the anti-reverse mechanism 191 can abut against the end face of the extension section 133 away from the mounting section 132, thereby limiting the stroke of the rotating rod 310.
[0056] Please refer to the following: Figure 9 and Figure 10 This application also provides a header 100 of another embodiment. Compared with the previous embodiment, the difference lies in the different ways in which the first tube 130 and the second tube 140 are formed. The following only describes the different parts in detail. For the same parts, please refer to the content of the previous embodiment. They will not be repeated here.
[0057] In this embodiment, the housing 100 includes a first tube 130 and a second tube 140. The first tube 130 has a first through hole 134, and the second tube 140 has a second through hole 141. The first tube 130 and the second tube 140 are connected, and the first through hole 134 and the second through hole 141 are in communication. The housing 100 includes a middle frame 110 and a decorative member 180. The middle frame 110 forms the first tube 130. Specifically, the side frame 111 of the middle frame 110 forms the first tube 130. The decorative member 180 is attached to the outer surface 114 of the middle frame 110, and the decorative member 180 forms the second tube 140. That is, in this embodiment, there is no need to set up a separate tubular structure. The first through hole 134 is directly opened in the middle frame 110, and the second through hole 141 corresponding to the first through hole 134 is opened in the decorative member 180, so that the first through hole 134 and the second through hole 141 are in communication.
[0058] In this embodiment, the decorative part 180 can be fixed to the middle frame 110 by adhesive bonding. In other embodiments, the decorative part 180 can also be fixed to the middle frame 110 by riveting, snap-fitting, etc. This embodiment does not limit this.
[0059] This implementation completely eliminates the need for separate first tube 130 and second tube 140, further reducing the number of parts and making the assembly of the entire crown assembly 300 more convenient. Specifically, in this embodiment, a first through hole 134 is formed in the side frame 111 and penetrates the inner surface 113 and the outer surface 114, and a second through hole 141 penetrates the decorative piece 180. The first through hole 134 and the second through hole 141 are arranged adjacent to each other and are substantially coaxial. The end of the decorative piece 180 away from the middle frame 110 is at least partially embedded in the gap 323 between the side plate 322 and the rotating rod 310. The side plate 322 shields the decorative piece 180 and the second through hole 141.
[0060] The diameters of the first through hole 134 and the second through hole 141 can be the same to ensure that the crown assembly 300 can be installed safely. After the crown assembly 300 is inserted into the first through hole 134 and the second through hole 141, in order to improve the sealing between the rotating rod 310 and the middle frame 110, the crown assembly may further include a second sealing ring 170. The second sealing ring 170 is disposed between the rotating rod 310 and the middle frame 110, or between the rotating rod 310 and the mounting component 180. The second sealing ring 170 may be made of an elastic material, such as silicone or rubber. In this embodiment, there are two second sealing rings 170, which are spaced 323 apart and arranged approximately at the center of the rotating rod 310. This design prevents external dust and moisture from entering the inner cavity 101 through the gap between the first tube 130 and the rotating rod 310. Specifically, one second sealing ring 170 is disposed between the rotating rod 310 and the middle frame 110, and the other second sealing ring 170 is disposed between the rotating rod 310 and the mounting component 180. This arrangement can simultaneously create a stable sealing effect between the rotating rod 310 and the middle frame 110, and between the rotating rod 310 and the mounting component 180. Of course, it is understood that in some other embodiments, the second sealing ring 170 may only be disposed between the rotating rod 310 and the middle frame 110, or only between the rotating rod 310 and the mounting component 180. This embodiment does not limit this.
[0061] To facilitate the installation of the second sealing ring 170, a second slot 311 is provided on the outer wall of the rotating rod 310. The second sealing ring 170 abuts against the first tube body 130 and is at least partially embedded in the second slot 311. By providing the second slot 311, the position of the second sealing ring 170 can be fixed, preventing the second sealing ring 170 from sliding along the axial direction of the first tube body 130, thus achieving a better sealing effect. Simultaneously, after the second sealing ring 170 is embedded in the second slot 311, the sealing effect between the second sealing ring 170 and the second tube body 140 can be further improved. In other embodiments, the second slot 311 can also be provided on the inner wall of the first through hole 134 of the side frame 111; this embodiment does not limit this.
[0062] In this embodiment, since the first through hole 134 and the second through hole 141 are formed directly by the middle frame 110 and the decorative part 180 respectively, when performing sealing assembly, it is only necessary to seal between the inner wall of the swivel rod 310 and the first through hole 134, which can further reduce the number of sealing parts and reduce the assembly difficulty.
[0063] In this embodiment, the watch head and wearable device 10 are provided. The first tube 130 and the second tube 140 are connected to form a first through hole 134 and a second through hole 141 for mounting the crown assembly 300. The rotating rod 310 of the crown assembly 300 can be rotatably disposed in the first through hole 134 and the second through hole 141. The entire mounting structure of the crown assembly 300 has fewer parts. At the same time, the second tube 140 is embedded in the gap 323 between the side plate 322 and the rotating rod 310. The side plate 322 can shield the rotating rod 310 and the second tube 140, so that when the crown assembly 300 is installed, the knob part 320 can directly shield the second tube 140 without the need for additional parts to cover the second through hole 141 or the second tube 140. The overall appearance is more consistent and the sealing effect is better.
