Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and more particularly to a detachable main unit structure and a smartwatch. Background Technology

[0002] With the rapid development of technology, various smart wearable devices are permeating all aspects of people's lives, bringing tremendous changes to their daily routines and perceptions. Wearable devices are not merely hardware devices; they achieve their powerful functions through software support, data interaction, and cloud interaction. Their applications are very broad, including healthcare, fitness, and communication. For example, watches are no longer limited to simply telling time. By embedding intelligent hardware and running a smartphone operating system connected to the network, they can perform various functions such as making calls, sending text messages, emails, viewing photos, and listening to music and videos. Smartwatches are an extension and expansion of smartphone functions, bringing great convenience to people's daily lives.

[0003] Some smartwatches on the market feature a flip and / or rotate mechanism, allowing the main unit to rotate relative to the tray, thus changing the orientation of the screen and camera for easier access to information, video calls, and photography. Under normal circumstances, the main unit cannot be detached from the tray; it always moves with the user's wrist and cannot be disassembled for independent use. This design limitation restricts the main unit's application scenarios, preventing it from meeting the diverse needs of users like a smartphone, such as taking photos, videos, and making video calls independently. Furthermore, the limited range of motion of the main unit prevents arbitrary adjustment of the screen's direction, significantly restricting the smartwatch's application scenarios.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable main unit structure and a smartwatch. A connecting component mates with the main unit and the tray, allowing the main unit to be oriented at any angle relative to the tray. This enables the user to change the orientation of the main unit without rotating their wrist, ensuring the screen remains within their field of vision. Furthermore, rotating the contact block presses against two locking components to release the restriction between the main unit and the tray. This allows the main unit to be used independently after detachment, without being limited by wrist constraints, thus significantly improving the user experience.

[0006] The technical solution provided by this invention is as follows:

[0007] In a first aspect, the present invention provides a detachable host structure, comprising:

[0008] Pallet, main unit, and connecting components for driving the main unit to flip and rotate relative to the pallet;

[0009] The connecting member is characterized in that it includes a rotating assembly and two locking assemblies;

[0010] The tray has a receiving portion at its end, and two locking assemblies are symmetrically arranged in the receiving portion;

[0011] The rotating assembly includes a base shell, a contact block, a rotating component, and a flipping component;

[0012] The base shell has a latch groove on each of its opposite sides for engaging with the latch assembly;

[0013] The base shell is located within the receiving portion; the contact block is located within the base shell and is used to engage the rotating component;

[0014] The flipping component is mounted on the rotating component to dock with the main unit;

[0015] The host causes the contact block to rotate and switch between a first state and a second state during the rotation process;

[0016] In the first state, the two locking components are respectively engaged in the two locking slots to assemble the main unit onto the tray;

[0017] In the second state, the contact block presses the two locking assemblies to the slots of the two locking grooves, applying a force to the main unit away from the tray, causing the base shell to detach from the two locking assemblies, thereby achieving separation of the main unit and the tray.

[0018] In some embodiments, a groove is provided on each of the two opposing inner wall surfaces of the receiving portion;

[0019] When the base shell is located inside the receiving part, the two sliding grooves and the two fastening grooves are provided in a one-to-one correspondence;

[0020] The locking assembly includes an elastic element and a latch;

[0021] The elastic element is used to fix the latch to the groove;

[0022] In its natural state, the elastic element drives the latch to extend into the latch groove, thereby locking the base shell into the receiving part and realizing the assembly of the main unit and the tray.

[0023] During rotation, the contact block presses against the latch, causing the latch to spring back towards the inside of the groove, thereby releasing the restriction between the latch and the groove, allowing the main unit to detach from the tray when subjected to external force.

[0024] In some embodiments, the lower end wall of the latch on the side away from the elastic member is provided with a first guide slope; and

[0025] The lower edge of the groove is provided with an extruded arc surface;

[0026] During rotation, the contact block presses against the latch, causing the first guide slope to contact the pressing arc surface, applying a force to the main unit away from the tray. During the movement of the base shell, the pressing arc surface presses against the first guide slope, causing the latch to disengage from the latch groove, thereby detaching the main unit from the tray.

[0027] In some embodiments, the upper end wall of the latch on the side away from the elastic member is provided with a second guide slope; and

[0028] The upper end wall of the buckle groove is provided with a mating inclined surface;

[0029] The second guide slope and the mating slope are used together to guide the buckle tongue into the buckle groove.

[0030] In some embodiments, the contact block has a first pressing end and a second pressing end disposed opposite to each other;

[0031] The distance between the first extrusion end and the second extrusion end is greater than the distance between the two ends of the contact block perpendicular to the first extrusion end and the second extrusion end;

[0032] The first pressing end and the second pressing end are respectively used to press the two locking components.

[0033] In some embodiments, the contact block has a diamond-shaped structure, and the portions of the first and second pressing ends that engage with the locking assembly have an arc-shaped transition; and / or

[0034] The receiving part has a square groove structure, and the base shell has a square shell structure that matches the contour of the receiving part. The base shell has a working position inside for the contact block to rotate.

[0035] In some embodiments, the rotating member includes a rotating shaft, and the contact block is disposed at the bottom end of the rotating shaft; and

[0036] A rotating hole is provided at the middle position of the upper end face of the base shell, and the rotating shaft extends through the rotating hole to the top of the base shell to engage with the flipping component, so as to fix the contact block inside the base shell.

[0037] In some embodiments, the flipping component includes a rotating plate and two rotating connecting components disposed at opposite ends of the rotating plate;

[0038] The rotating plate has a socket in the middle for inserting the rotating shaft;

[0039] The main unit is rotatably connected to the two rotating connecting members. The main unit can be operably flipped relative to the rotating plate and the rotating shaft can be rotated relative to the tray so that the main unit has different orientations.

[0040] In some embodiments, the rotating member further includes a damping member disposed on the rotating shaft;

[0041] The bottom of the rotating plate is provided with a circular groove coaxially arranged with the insertion hole, and the bottom of the circular groove is provided with two symmetrically arranged recesses; and

[0042] The upper end of the base shell is provided with a frustum coaxially arranged with the rotating hole, and the top of the frustum is provided with two symmetrically arranged protrusions.

[0043] The damping element is used to apply a force to the rotating plate against the base shell, so that the frustum and the groove abut and rotate. During the process of the main unit driving the rotating shaft to rotate, when the rotating plate rotates 0° or 180° relative to the support plate, the two protrusions and the two recesses respectively engage.

[0044] In a second aspect, the present invention also provides a smartwatch, comprising:

[0045] Watch strap; and

[0046] The aforementioned detachable main unit structure;

[0047] The tray has a first mounting portion and a second mounting portion that are disposed opposite to each other;

[0048] The first mounting portion is used for mounting one end of the watch strap, and the second mounting portion is used for mounting the other end of the watch strap.

[0049] The technical effects of this invention are as follows:

[0050] In this patent, the rotating component allows the main unit to flip and rotate relative to the tray, enabling the main unit to face at any angle relative to the tray and maintain this tilted posture at all times. This allows the user to change the orientation of the main unit without turning their wrist, bringing the screen into the user's field of vision, greatly simplifying the screen adjustment process and improving the user experience. Furthermore, the touch block, during rotation, presses against the two locking components to release the restriction between the main unit and the tray, allowing the main unit to be directly removed from the tray under external force and used independently in multiple scenarios, such as taking photos, videos, and browsing the internet, just like a mobile phone, greatly expanding the application scenarios of the main unit.

Detailed Implementation

[0067] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0068] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0069] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0070] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0071] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0072] According to a specific embodiment provided by the present invention, such as Figures 1 to 13 As shown, the present invention provides a detachable host structure 100 in a first aspect, including a tray 2, a host 3, and a connecting member 1 for driving the host 3 to flip and rotate relative to the tray 2. The connecting member 1 includes a rotating component 11 and two locking components 12. The tray 2 has a receiving portion 21 at its end, and the two locking components 12 are symmetrically arranged in the receiving portion 21. The rotating component 11 includes a base shell 111, a contact block 112, a rotating member 113, and a flipping member 114. The base shell 111 has a latching groove 1111 on each side for engaging with the locking components 12. The base shell 111 is located in the receiving portion 21, and the contact block 112 is located in the base shell 111 for engaging with the rotating member 113. The flipping member 114 is installed on the rotating member 113 for engaging with the host 3, and the host 3 rotates the contact block 112 between a first state and a second state during rotation. In the first state, the two locking assemblies 12 are respectively engaged in the two locking slots 1111 to assemble the main unit 3 onto the tray 2. In the second state, the contact block 112 presses the two locking assemblies 12 to the opening of the two locking slots 1111, applying a force to the main unit 3 away from the tray 2, causing the base shell 111 to detach from the two locking assemblies 12, thereby separating the main unit 3 from the tray 2.

[0073] In this embodiment, the rotating component 11 allows the host 3 to be flipped and rotated relative to the tray 2, enabling the host 3 to have any angle of orientation relative to the tray 2 and to maintain this tilted posture at all times. This allows the user to change the orientation of the host 3 at will without turning their wrist, so that the screen 33 can enter the user's field of vision, greatly simplifying the adjustment steps of the screen 33 and improving the user experience. Furthermore, the contact block 112 can release the restriction between the host 3 and the tray 2 by pressing the two locking components 12 during rotation, so that the host 3 can be directly removed from the tray 2 under the action of external force and used independently in multiple scenarios, such as taking pictures, taking videos, and browsing the Internet, which can greatly expand the application scenarios of the host 3.

[0074] It is worth mentioning that in this embodiment, the host 3 is initially stacked on the tray 2. A screen 33 is provided on the side of the host 3 facing away from the tray 2, and a camera is also provided on this side adjacent to the host 3. The camera is preferably located in the middle of the upper part of the screen 33, but is not limited to this. When the user operates the host 3 to flip and rotate it relative to the tray 2, the camera and screen 33 can move with the host 3 to allow the user to find the optimal video imaging angle to meet practical usage needs.

[0075] Of course, the present invention also provides a smartwatch in a second aspect, specifically including a watch strap and the detachable main unit structure 100 provided in the first aspect of the present invention. See also... Figures 1 to 5 The tray 2 has a first mounting part 22 and a second mounting part 23 arranged opposite to each other. The first mounting part 22 is arranged adjacent to the connecting member 1 and is used for mounting one end of the watch strap. The second mounting part 23 is located at the opposite end of the tray 2 and is used for mounting the other end of the watch strap.

[0076] When using this smartwatch, users can adjust the tilt of the main unit 3 relative to the base plate 2 in real time according to their own usage habits to change the angle of video and photo taking, thereby achieving better call and photo effects. Furthermore, compared to traditional smartwatches where the main unit 3 is not adjustable, this invention, by adjusting the tilt of the main unit 3, can effectively prevent wrist pain caused by prolonged video recording, providing users with a better experience while using the smartwatch.

[0077] It is worth mentioning that this embodiment does not impose any restrictions on the specific structure of the watch strap. For example, it can be an elastic band, with its two ends respectively used to connect to the first mounting part 22 and the second mounting part 23 of the support plate 2. The elasticity of the elastic band itself can automatically fix the main unit 3 to the user's wrist. Of course, the watch strap can also be two separate straps connected by a buckle. The ends of the two separate straps are respectively used to install and fix to the first mounting part 22 and the second mounting part 23, all of which are within the protection scope of this patent. As for the installation method of the watch strap to the first mounting part 22 and the second mounting part 23, it is not specifically limited here. It can be fixedly connected by a pivot, or it can be fixed by welding or buckling, etc., all of which are within the protection scope of this patent and will not be elaborated on here. It can be flexibly changed according to the user's preferences.

[0078] It is worth mentioning that, when the main unit 3 is rotated to be stacked on the tray 2, or when the main unit 3 is in its initial non-rotated state, in order to ensure that the main unit 3 will not automatically flip off the tray 2 due to external forces, such as wrist movements, during use, a buckle 24 is preferably provided on the tray 2 near the second mounting part 23, that is, at the end away from the connecting member 1. Correspondingly, the side of the main unit 3 facing away from the screen 33 has a buckle groove 1111 that matches the buckle 24. When the main unit 3 is stacked on the tray 2, the buckle 24 and the buckle groove 1111 engage with each other to prevent the main unit 3 from detaching from the tray 2. Of course, the tray 2 may also have a buckle groove 1111 and the main unit 3 may also have a buckle 24, or the main unit 3 and the tray 2 may be magnetically engaged by a magnetic component. That is to say, any structural method that can fix the main unit 3 and the tray 2 is within the protection scope of this patent and is not limited here.

[0079] Furthermore, an operating part 34 is provided at one end of the main unit 3 adjacent to the latching groove 1111. In this embodiment, the operating part 34 can be formed directly by providing anti-slip texture on the end of the main unit 3, or it can be formed by providing anti-slip rubber on the end of the main unit 3; no limitation is made here. At this time, the user only needs to touch the operating part 34 and apply a force to the operating part 34 away from the tray 2. When the force is greater than the force of the latch 24 and the latching groove 1111 engaging, the main unit 3 can be flipped up from the tray 2 under the action of the connecting member 1, forming an angle with the tray 2. The user can flexibly adjust the tilt of the main unit 3 relative to the tray 2 according to their actual usage needs to meet their actual usage requirements.

[0080] In this embodiment, see Figures 3 to 6 The receiving part 21 can be directly injection molded integrally with the pallet 2, and is preferably molded at the middle position of one end of the pallet 2. The receiving part 21 can be a hollow protruding structure, and the upper end of the receiving part 21 has an opening for the base shell 111 to enter into the receiving part 21 and to be removed from the receiving part 21.

[0081] It is worth mentioning that, in this embodiment, see Figures 3 to 6 The receiving portion 21 is preferably a square groove structure, and the base shell 111 is preferably a square shell structure adapted to the contour of the receiving portion 21. Thus, when the base shell 111 is located within the receiving portion 21, the square structure effectively prevents lateral movement of the base shell 111 within the receiving portion 21, thereby greatly improving the stability of the main unit 3 during use and enhancing the user experience. Of course, the specific construction of the receiving portion 21 and the base shell 111 is not limited to these and can be flexibly designed according to actual usage requirements, all of which are within the scope of protection of this patent and will not be elaborated further here.

[0082] Further, see Figure 4 and Figure 6 Preferably, a sliding groove 211 is provided at the middle position of the two opposing inner wall surfaces of the receiving part 21 for assembling the locking assembly 12. When the base shell 111 is located in the receiving part 21, the two sliding grooves 211 and the two locking slots 1111 correspond one-to-one and are arranged close to or fitted together, so that the locking assembly 12 can extend into the locking slot 1111 to assemble the main unit 3 onto the tray 2.

[0083] As a preferred embodiment, see [link to example]. Figures 7 to 13 The locking assembly 12 specifically includes an elastic element 121 and a latch 122. The elastic element 121 is used to fix the latch 122 to the slide groove 211. In its natural state, the elastic element 121 drives the latch 122 to extend into the latch groove 1111 to assemble the main unit 3 onto the tray 2. Further, as the contact block 112 rotates inside the base shell 111, it presses the latch 122, causing the latch 122 to spring back towards the inside of the slide groove 211 to release the restriction between the latch 122 and the latch groove 1111, allowing the main unit 3 to detach from the tray 2 under external force.

[0084] In this embodiment, the elastic element 121 is preferably a spring, with one end fixed to the bottom of the groove 211 and the other end used to engage with the latch 122. It is worth mentioning that, to improve the stability of the latch 122 during its sliding along the groove 211, a base plate 123 can be provided at the bottom of the latch 122. The base plate 123 is used to drive the latch 122 to slide back and forth along the groove 211 during the extension and retraction of the spring. More importantly, in its natural state, the latch 122 extends at least partially outside the groove 211 to engage with the latch groove 1111 of the base shell 111, thereby locking the base shell 111 inside the latch groove 1111 and facilitating the assembly between the main unit 3 and the tray 2. Of course, the elastic element 121 can also be any elastically extendable component, such as a rubber column, without specific limitations, all of which are within the scope of this patent.

[0085] In this embodiment, when the two ends of the contact block 112 fully compress the two latches 122, causing the two latches 122 to rebound to their limit state, at least a portion of the two latches 122 at the end away from the elastic member 121 remains inside the latch groove 1111. Thus, when the main unit 3 is not subjected to external force, that is, when the user does not apply a force to the main unit 3 away from the tray 2, the base shell 111 remains confined within the receiving portion 21, meaning the main unit 3 remains connected to the tray 2 and will not automatically detach from the tray 2. At this time, the user only needs to apply a force to the main unit 3 away from the tray 2, and the base shell 111 can compress the latches 122 under the action of external force, causing the latches 122 to completely detach from the latch groove 1111, ultimately achieving the separation of the main unit 3 and the tray 2.

[0086] As a preferred embodiment, see [link to example]. Figures 11 to 13 The lower end wall of the latch 122, away from the elastic element 121, is provided with a first guide slope 1221. Correspondingly, the lower edge of the latch groove 1111 is provided with a pressing arc surface 1112. During rotation, the contact block 112 presses the latch 122. When the two latches 122 rebound to their limit state, the first guide slope 1221 contacts the pressing arc surface 1112. At this time, the user only needs to apply a force to the main unit 3 away from the tray 2. The pressing arc surface 1112 presses the first guide slope 1221 during the movement of the base shell 111, causing the latch 122 to disengage from the latch groove 1111, thereby removing the main unit 3 from the tray 2.

[0087] Further, see also Figures 11 to 13 The upper end wall of the latch 122, away from the elastic member 121, is provided with a second guide slope 1222. Correspondingly, the upper end wall of the latch groove 1111 is provided with a mating slope 1113 with the same inclination as the second guide slope 1222. The second guide slope 1222 and the mating slope 1113 work together to guide the latch 122 to quickly and smoothly engage with the latch groove 1111, ensuring that the latch 122 is not obstructed during its entry into the latch groove 1111.

[0088] In this embodiment, the contact block 112 has a first pressing end 1121 and a second pressing end 1122 disposed opposite to each other. The first pressing end 1121 and the second pressing end 1122 are respectively used to press and engage with the two latches 122. In this embodiment, in order to ensure that when the first pressing end 1121 and the second pressing end 1122 are not in contact with the two latches 122 and thus do not affect the limiting engagement between the latches 122 and the latching grooves 1111, the line distance between the first pressing end 1121 and the second pressing end 1122 can be set to be greater than the line distance between the two ends of the contact block 112 perpendicular to the first pressing end 1121 and the second pressing end 1122. In this way, it can be ensured that in the first state, the two latches 122 are respectively engaged in the two latching grooves 1111 to assemble the main unit 3 onto the tray 2. And ensure that in the second state, the contact block 112 presses the two latches 122 into the slots of the two latches 1111 respectively, so that the user can apply a force to the host 3 away from the tray 2, so that the base shell 111 is separated from the two latches 122, thereby realizing the separation of the host 3 and the tray 2.

[0089] As a preferred embodiment, see [link to example]. Figures 9 to 13The contact block 112 can be in the form of a rhomboid block, and the portions of the first pressing end 1121 and the second pressing end 1122 used for engaging the latch 122 have an arc-shaped transition. This facilitates smooth engagement and disengagement of the contact block 112 and the latch 122, preventing jamming and friction, thereby greatly improving the user experience. Of course, the structure of the contact block 112 is not limited to this; it can also be any regular or irregular structure, all of which are within the scope of this patent and will not be elaborated further here.

[0090] Further, see Figures 9 to 11 The base shell 111 has a station 1116 inside for the contact block 112 to rotate. The specific structure of the station 1116 is not limited here. That is to say, the station 1116 only needs to ensure that the contact block 112 is not obstructed during rotation inside the base shell 111. It is preferably in the shape of a circular groove 11412, but is not limited thereto.

[0091] In this embodiment, see Figure 4 and Figures 8 to 13 The rotating component 113 may include a rotating shaft 1131, with a contact block 112 disposed at the bottom end of the rotating shaft 1131. Further, a rotating hole 1114 is provided at the middle position of the upper surface of the base shell 111, through which the rotating shaft 1131 extends to the top of the base shell 111 to engage with the flipping component 114, thereby fixing the contact block 112 inside the base shell 111. Preferably, the contact block 112 and the rotating shaft 1131 can be an integral design, which greatly improves the structural stability between the two. Of course, a separate assembly scheme can also be used between the contact block 112 and the rotating shaft 1131, all of which are within the scope of protection of this patent.

[0092] Furthermore, the flipping component 114 may include a rotating plate 1141 and two rotating connecting components 1142 respectively disposed at opposite ends of the rotating plate 1141. The rotating plate 1141 has an insertion hole 11411 for inserting the rotating shaft 1131 at its middle position. The main unit 3 is rotatably connected to the two rotating connecting components 1142, and the main unit 3 can be operably flipped relative to the rotating plate 1141 and drive the rotating shaft 1131 to rotate relative to the support plate 2, so that the main unit 3 has different orientations.

[0093] Specifically, see Figures 8 to 11When the upper end of the rotating shaft 1131 extends above the base shell 111 through the rotating hole 1114, the insertion hole 11411 of the rotating plate 1141 can be aligned with the rotating shaft 1131, so that the rotating plate 1141 moves axially along the rotating shaft 1131 and abuts against the upper end face of the base shell 111. It is worth mentioning that the transverse cross section of the rotating shaft 1131 can be D-shaped, and the insertion hole 11411 is also a D-shaped hole adapted to the rotating shaft 1131. In this way, when the rotating plate 1141 is assembled on the rotating shaft 1131, the host 3 can drive the rotating plate 1141 to rotate during the rotation process, thereby driving the rotating shaft 1131 and the contact block 112 to rotate synchronously.

[0094] Further, see Figure 4 , Figure 7 , Figure 8 and Figure 9 The rotating component 113 also includes a damping component 1132 disposed on the rotating shaft 1131. The bottom of the rotating plate 1141 has a circular groove 11412 coaxially arranged with the insertion hole 11411. The bottom of the circular groove 11412 has two symmetrically arranged recesses 11413, and the connection between the two recesses 11413 and the remaining area of ​​the bottom of the circular groove 11412 is smooth. Correspondingly, the upper end of the base shell 111 has a frustum 1115 coaxially arranged with the rotating hole 1114. The top of the frustum 1115 has two symmetrically arranged protrusions 11151, and the connection between the two protrusions 11151 and the remaining area of ​​the top of the frustum 1115 is smooth. The contours of the two protrusions 11151 and the two recesses 11413 are all compatible. The damping element 1132 applies a force to ensure the rotating plate 1141 fits tightly against the base shell 111, causing the frustum 1115 and the circular groove 11412 to abut and rotate. During the rotation of the rotating shaft 1131 driven by the main unit 3, when the rotating plate 1141 rotates 0° or 180° relative to the support plate 2, the two protrusions 11151 engage with the two recesses 11413 respectively. This allows the rotating plate 1141 to produce a blunt feel during rotation, making it easier for the user to know the rotation angle. Specifically, when the rotating plate 1141 rotates to the position where the two protrusions 11151 and the two recesses 11413 engage, the rotating plate 1141 stops rotating under the limiting action of the two protrusions 11151 and the two recesses 11413, thus limiting the rotating plate 1141 relative to the support plate 2 at the 0° or 180° position. When the user wants to rotate the main unit 3 again, he only needs to apply a force to overcome the locking force of the two protrusions 11151 and the two recesses 11413 to make the two protrusions 11151 disengage from the two recesses 11413, which can also improve the user's feel when rotating the main unit 3.

[0095] Preferably, in this embodiment, the main unit 3 can rotate when it is flipped to a position perpendicular to the tray 2. Specifically, when the main unit 3 rotates to a position parallel to the line connecting the first mounting portion 22 and the second mounting portion 23 of the tray 2, the first pressing end 1121 and the second pressing end 1122 of the contact block 112 abut against the two latches 122, placing the two latches 122 in their maximum retracted position. This position allows the user to quickly and smoothly remove the main unit 3 from the base plate 123.

[0096] Furthermore, in this embodiment, see Figure 4 The damping element 1132 may include a telescopic element 11321, a sleeve 11322, and a fastener 11323. This embodiment uses a spring as an example for specific description of the telescopic element 11321, but it is not limited to this. Specifically, a protrusion 11311 is provided at the upper end of the rotating shaft 1131, that is, at the end away from the contact block 112. The protrusion 11311 is coaxially arranged with the rotating shaft 1131, and its diameter is smaller than the diameter of the rotating shaft 1131. The spring is sleeved on the rotating shaft 1131, with one end abutting against the rotating plate 1141. The fastener 11323 is installed on the protrusion 11311 to abut against the other end of the spring. In this way, under the elastic action of the spring, the rotating plate 1141 can be tightly fitted against the upper end surface of the base shell 111, so that the frustum 1115 and the circular groove 11412 abut and rotate.

[0097] Furthermore, the sleeve 11322 is fitted onto the spring and abuts against the rotating plate 1141. The sleeve 11322 can protect the spring to extend its service life, and at the same time, it can effectively prevent the main unit 3 from rotating along the support plate 2, thereby improving the stability of the main unit 3 in maintaining its current state.

[0098] Furthermore, the flipping component 114 also includes a protective cover 1143, which is mounted on the rotating plate 1141 to provide effective protection for components such as the damping component 1132. In this embodiment, see... Figure 2The end of the main unit 3 is provided with a clearance portion 31 that matches the contour of the protective cover 1143. Specifically, in this embodiment, each rotating connector 1142 has a shaft hole 11421, and a flip shaft 11423 passes through each shaft hole 11421. Further, a connector is installed at the end of the flip shaft 11423 for docking with the main unit 3. Specifically, the connecting piece 11422 may include an L-shaped first part 114221 and a second part 114222, and the first part 114221 is fixed to the end of the rotating connector 1142 by the flip shaft 11423. Correspondingly, the opposite ends of the clearance portion 31 are respectively provided with connecting grooves 32 that match the contour of the connecting piece 11422. Specifically, the connecting grooves 32 include an L-shaped first groove 321 and a second groove 322. The first slot 321 is used to connect with the first part 114221, and the second slot 322 is used to connect with the second part 114222. The second part 114222 and the second slot 322 are fixedly connected by screws 1144. Thus, during the flipping process of the main unit 3, the flipping shaft 11423 can rotate along the rotating connector 1142 to adjust the tilt angle of the main unit 3. It is worth mentioning that a stop 11424 is also provided between the flipping shaft 11423 and the shaft hole 11421. This stop 11424 is preferably a rubber ring, but is not limited to this. The stop 11424 provides a corresponding damping force during the rotation of the main unit 3, ensuring that the main unit 3 maintains its rotated position and does not easily rotate, greatly improving the user experience.

[0099] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
