Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a tray assembly and wearable device. Background Technology

[0002] With the development of wearable electronic products such as smartwatches, smart bracelets, and smart glasses, wearable devices with flip-up main units are being used more and more frequently.

[0003] In related technologies, wearable devices may include a tray assembly and a main unit, with the main unit movably mounted on the tray assembly. The tray assembly typically includes a wrapping component and an inner liner embedded within it. To meet the demand for thinness and lightness, both the inner liner and the wrapping component are usually made relatively thin, resulting in a thinner tray assembly. However, during use, the inner liner is prone to deformation or breakage under stress, causing the main unit to easily detach from the tray assembly, leading to a poor user experience. Utility Model Content

[0004] This application discloses a tray assembly and a wearable device, which enables the tray assembly to have high structural strength, effectively reduces the probability of deformation and breakage of the inner lining in the tray assembly, and improves the user experience.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a tray assembly for supporting the main unit of a wearable device, comprising:

[0006] The inner liner has a first surface supporting the main unit and a second surface facing away from the main unit. The inner liner has a ring structure and includes an inner ring portion and an outer ring portion. The outer ring portion is connected to the outer peripheral surface of the inner ring portion and is along a first direction. The size of the inner ring portion is larger than the size of the outer ring portion. The first direction is the arrangement direction of the first surface and the second surface.

[0007] A package that covers at least a portion of the outer surface of the liner, wherein the structural strength of the liner is greater than the structural strength of the package.

[0008] In this embodiment, by covering at least part of the outer surface of the inner liner with the wrapping component, and the structural strength of the inner liner being greater than that of the wrapping component, the tray assembly can have better structural strength, reducing the probability of deformation or breakage of the tray assembly under stress, thereby enabling the wearable device assembled with the tray assembly to have higher quality.

[0009] The outer ring of the inner liner is connected to the outer circumferential surface of the inner ring. Along the first direction, the size of the inner ring is larger than the outer ring, allowing the inner liner to have an irregular cross-section, such as a T-shaped or L-shaped structure. Compared to an inner liner with a ring structure and a straight cross-section, with the same width and thickness, the irregularly shaped inner liner has higher structural strength and lower weight, reducing the likelihood of deformation or breakage. This results in higher structural strength for the pallet assembly, effectively reducing the chance of deformation or breakage during use. This also prevents the main unit from easily coming undone due to deformation or breakage of the pallet assembly, improving the user experience.

[0010] In one possible implementation of the first aspect, the first surface is at least partially exposed to form a first annular exposed surface.

[0011] In one possible implementation of the first aspect, the first surface is partially exposed corresponding to the inner ring portion to form the first annular exposed surface.

[0012] In one possible implementation of the first aspect, the portion of the first annular exposed surface near the central hole of the liner is formed with an abutment structure for abutting with the mold, the abutment structure including an abutment ramp or an abutment groove.

[0013] In one possible implementation of the first aspect, the package includes a first covering portion covering the surface of the inner ring portion facing the central hole. When the abutting structure includes the abutting ramp, the surface of the first covering portion facing the central hole is smoothly connected to the abutting ramp. When the abutting structure includes the abutting groove, the surface of the first covering portion facing the host is flush with the bottom surface of the abutting groove.

[0014] In one possible implementation of the first aspect, the package includes a first covering portion that covers the surface of the inner ring portion facing the central hole of the liner;

[0015] A first connecting portion is provided on the surface of the inner ring portion facing the first covering portion, and a second connecting portion is provided on the surface of the first covering portion facing the inner ring portion. The first connecting portion includes one of a groove and a protrusion, and the second connecting portion includes the other of a groove and a protrusion. The protrusion is embedded in the groove.

[0016] In one possible implementation of the first aspect, the inner ring portion has its surface exposed toward the central hole of the liner.

[0017] In one possible implementation of the first aspect, the second surface is partially exposed corresponding to the inner ring portion to form a second annular exposed surface.

[0018] In one possible implementation of the first aspect, along the first direction, there is a height difference between the surface of the outer ring portion facing the host and the surface of the inner ring portion facing the host, and the surface of the outer ring portion away from the host is flush with or has a height difference from the surface of the inner ring portion facing the host.

[0019] In one possible implementation of the first aspect, the outer ring portion has opposing first and second edges on the surface away from the host, the first edge being connected to the inner ring portion, and the outer ring portion being at least partially inclined on the surface away from the host, such that the second edge is close to the first surface relative to the first edge.

[0020] In one possible implementation of the first aspect, the width of one side of the liner is 2.5 mm to 4.3 mm along the radial direction of the central hole of the liner.

[0021] Secondly, this application also discloses a wearable device, comprising:

[0022] Host;

[0023] The pallet assembly described in any one of the first aspects, wherein the main unit is rotatably disposed on the pallet assembly.

[0024] Compared with the prior art, this application has at least the following beneficial effects:

[0025] The outer ring of the inner liner is connected to the outer circumferential surface of the inner ring. Along the first direction, the size of the inner ring is larger than the outer ring, allowing the inner liner to have an irregular cross-section, such as a T-shaped or L-shaped structure. Compared to an inner liner with a ring structure and a straight cross-section, with the same width and thickness, the irregularly shaped inner liner has higher structural strength and lower weight, reducing the likelihood of deformation or breakage. This results in higher structural strength for the pallet assembly, effectively reducing the chance of deformation or breakage during use. This also prevents the main unit from easily coming undone due to deformation or breakage of the pallet assembly, improving the user experience. Attached Figure Description

[0051] This utility model provides a tray assembly and wearable device, which enables the tray assembly to have high structural strength, effectively reduces the probability of deformation and breakage of the inner lining in the tray assembly, and improves the user experience.

[0052] The technical solution of this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0053] This application provides a tray assembly for supporting the main unit of a wearable device, such as... Figures 1-6 As shown, the pallet assembly 10 includes an inner liner 1 and a wrapping member 2. The inner liner 1 has a first surface 1a supporting the main unit and a second surface 1b facing away from the main unit. The inner liner 1 has a ring structure, including an inner ring portion 11 and an outer ring portion 12. The outer ring portion 12 is connected to the outer peripheral surface of the inner ring portion 11, and along a first direction, the size of the inner ring portion 11 is larger than the size of the outer ring portion 12. The first direction is the arrangement direction of the first surface 1a and the second surface 1b (e.g., ...). Figure 1 (in the direction shown by x); the package 2 covers at least part of the outer surface of the inner liner 1, and the structural strength of the inner liner 1 is greater than the structural strength of the package 2.

[0054] By covering at least part of the outer surface of the inner liner 1 with the wrapping component 2, the structural strength of the inner liner 1 is greater than that of the wrapping component 2, which can make the tray assembly 10 have better structural strength and reduce the probability of deformation, breakage, etc. when the tray assembly 10 is subjected to force, thereby making the wearable device assembled with the tray assembly 10 have higher quality.

[0055] The outer ring portion 12 of the inner liner 1 is connected to the outer peripheral surface of the inner ring portion 11. Along the first direction, the size of the inner ring portion 11 of the inner liner 1 is larger than the size of the outer ring portion 12. This allows the cross-section of the inner liner 1 to be an irregular structure, such as a T-shaped structure or an L-shaped structure. Compared to an inner liner 1 with a ring structure and a straight cross-section, the irregularly shaped inner liner 1 can have higher structural strength and lower weight under the same width and thickness. This reduces the probability of deformation or breakage of the inner liner 1, thereby enabling the pallet assembly 10 to have higher structural strength. This effectively reduces the probability of deformation or breakage of the pallet assembly 10 during use, making it less likely for the main unit to detach due to deformation or breakage of the pallet assembly 10, thus improving the user experience.

[0056] The first surface 1a of the inner liner 1 is used to support the main unit, so that the main unit can be more stable when supported on the pallet assembly 10.

[0057] It should be explained that the aforementioned inner liner 1 has a first surface 1a that supports the main unit. When the main unit is supported on the tray assembly 10, the first surface 1a of the inner liner 1 may be in direct contact with the main unit, or the first surface 1a of the inner liner 1 may not be in direct contact with the main unit. No limitation is made here.

[0058] The inner liner 1 has a ring structure, which reduces the weight of the inner liner 1 compared to a one-piece structure, thereby reducing the weight of the pallet assembly 10.

[0059] The inner lining 1 can be any of stainless steel, aluminum alloy, carbon fiber, etc., and is not limited here.

[0060] Wherein, the package 2 covers at least a portion of the outer surface of the inner liner 1, which may be a portion of the outer surface of the inner liner 1 or the entire outer surface of the inner liner 1, and is not limited here.

[0061] In addition, the package 2 can be used to cover at least part of the surface of the inner liner 1 through injection molding, so that the package 2 and the inner liner 1 have a high bonding force, which improves the connection between the package 2 and the inner liner 1 and thus improves the quality of the pallet assembly 10.

[0062] The aforementioned package 2 can be a plastic part with a certain degree of elasticity, so that the tray assembly 10 can have a better skin feel, improving the user's experience of wearing the device assembled with the tray assembly 10.

[0063] In addition, the tray assembly 10 is used to support the main unit of the wearable device. The main unit can be rotatably mounted on the tray assembly 10, or the main unit can be snapped onto the tray assembly 10. There is no limitation on this.

[0064] Optionally, such as Figures 4-6 As shown, the first surface 1a is at least partially exposed to form a first annular exposed surface 11a.

[0065] Therefore, when the package 2 is manufactured by injection molding, the first annular exposed surface 11a can be used to abut against the mold. Compared with the method of abutting against the mold through several spaced abutment points, and then filling these abutment points after injection molding, the manufacturing process of the pallet assembly 10 can be effectively simplified and the cost reduced. On the other hand, the abutment force from the mold on the inner liner 1 can be more uniform, and it is less likely to deform under stress, thus effectively improving the yield of the pallet assembly 10.

[0066] In addition, when the texture of the first annular exposed surface 11a is different from that of the package 2, the texture diversity of the tray assembly 10 can be increased, thus improving its aesthetics.

[0067] The first annular exposed surface 11a can be any of a plane, an inclined plane, or an arc surface, and is not limited to any one of them.

[0068] Optionally, the first surface 1a is partially exposed corresponding to the inner ring portion 11 to form a first annular exposed surface 11a.

[0069] Therefore, the inner ring 11 can play a certain positioning role in the contact between the mold and the inner liner 1, which makes it easier to put the inner liner 1 into and fix it on the mold, and improves the efficiency of fixing the inner liner 1 to the mold.

[0070] Among them, the inner ring portion 11 located within the first surface 1a can be higher than the outer ring portion 12 along the first direction, making it easier to position the contact between the mold and the inner liner 1.

[0071] like Figures 4-6 As shown, the portion of the first annular exposed surface 11a near the central hole of the inner liner 1 has an abutment structure 111. The abutment structure 111 is used to abut against the mold. The abutment structure 111 includes an abutment slope or an abutment groove.

[0072] Therefore, by abutting the mold with the inclined surface or the groove, it is easier to position the abutment between the mold and the inner liner 1, which further improves the efficiency of placing and fixing the inner liner 1 on the mold.

[0073] The side of the abutment groove facing the center hole of the inner liner 1 can be connected to the center hole of the inner liner 1, which further facilitates the abutment between the inner liner 1 and the mold, and makes it less likely for the wrapping part 2 to overflow onto the first annular exposed surface 11a during the injection molding process, thus further improving the yield.

[0074] In addition, the abutting slope can be any of the following: a plane, a slope, a curved surface, etc., and there is no limitation here.

[0075] Optionally, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the package 2 includes a first covering part 21, which covers the surface of the inner ring part 11 facing the central hole. When the abutting structure 111 includes an abutting slope, the surface of the first covering part 21 facing the central hole is smoothly connected to the abutting slope. When the abutting structure 111 includes an abutting groove, the surface of the first covering part 21 facing the host is flush with the bottom surface of the abutting groove.

[0076] Therefore, by smoothly transitioning the surface of the first covering part 21 facing the central hole to the abutting slope, or by making the surface of the first covering part 21 facing the host flush with the bottom surface of the abutting groove, the probability of the package 2 overflowing onto the first annular exposed surface 11a during the injection molding process can be effectively reduced, thereby improving the injection molding quality of the package 2, increasing the yield of the pallet assembly 10, and making the pallet assembly 10 more aesthetically pleasing.

[0077] By covering the surface of the inner ring 11 facing the central hole with the first covering part 21, the contact area between the wrapping part 2 and the inner liner 1 can be increased, which effectively improves the connection stability between the wrapping part 2 and the inner liner 1 and improves the quality of the pallet assembly 10.

[0078] The abutting slope is also smoothly connected to the first annular exposed surface 11a, which further improves the aesthetics.

[0079] The side of the abutment groove facing the center hole of the inner liner 1 can be connected to the center hole of the inner liner 1, so that the surface of the first covering part 21 facing the host and the bottom surface of the abutment groove can be connected, so that the surface of the first covering part 21 facing the host and the bottom surface of the abutment groove can form a stepped surface, which improves the aesthetics of the tray assembly 10.

[0080] In some embodiments, such as Figure 4 and Figures 8-12 As shown, when the package 2 includes a first covering portion 21, and the first covering portion 21 covers the surface of the inner ring portion 11 facing the central hole of the inner liner 1; a first connecting portion 112 may be provided on the surface of the inner ring portion 11 facing the first covering portion 21, and a second connecting portion 211 is provided on the first covering portion 21 facing the inner ring portion 11. The first connecting portion 112 includes one of a groove and a protrusion, and the second connecting portion 211 includes the other of a groove and a protrusion, with the protrusion embedded in the groove.

[0081] This effectively improves the bonding force between the inner liner 1 and the wrapping 2, enhances the connection stability between the inner liner 1 and the wrapping 2, and thus effectively improves the quality of the pallet assembly 10.

[0082] The cross-sectional shape of the groove can be any of the following: rectangular, trapezoidal, semi-circular, etc., without limitation. Similarly, the cross-sectional shape of the protrusion can also be any of the following: rectangular, trapezoidal, semi-circular, etc., as long as the protrusion matches the groove, without limitation.

[0083] In other embodiments, such as Figure 3 and Figure 6 As shown, the surface of the inner ring 11 facing the center hole of the inner liner 1 is exposed.

[0084] Therefore, the inner circumferential surface of the inner liner 1 does not need to be covered by the wrapping part 2, which effectively prevents the wrapping part 2 from overflowing onto the inner circumferential surface of the inner liner 1 during the injection molding process, resulting in better injection molding quality of the wrapping part 2, further improving the yield of the pallet assembly 10 and reducing costs.

[0085] When the portion of the first annular exposed surface 11a near the central hole of the inner liner 1 has an abutting structure 111, when the abutting structure 111 includes an abutting slope, the abutting slope can smoothly transition and connect with the surface of the inner ring portion 11 facing the central hole of the inner liner 1. When the abutting structure 111 includes an abutting groove, the abutting groove can be disposed at the connection between the first annular exposed surface 11a and the surface of the inner ring portion 11 facing the central hole of the inner liner 1, and the side of the abutting groove facing the central hole of the inner liner 1 communicates with the central hole of the inner liner 1 to form a stepped surface.

[0086] In other embodiments, such as Figure 3 and Figure 6 As shown, the second surface 1b is partially exposed corresponding to the inner ring portion 11, forming a second annular exposed surface 11b.

[0087] This allows the side of the tray assembly 10 facing away from the main unit to have two different textures: the inner ring 11 and the wrapping part 2, thus improving the user experience of the tray assembly 10.

[0088] The second annular exposed surface 11b can be any of a plane, an inclined plane, or an arc surface, and is not limited to any one of them.

[0089] Furthermore, the first surface 1a, corresponding to the partial exposure of the inner ring portion 11, forms a first annular exposed surface 11a, the surface of the inner ring portion 11 facing the central hole of the inner liner 1 is exposed, and the second surface 1b, corresponding to the partial exposure of the inner ring portion 11, forms a second annular exposed surface 11b. When the first annular exposed surface 11a, the surface of the inner ring portion 11 facing the central hole of the inner liner 1, and the second annular exposed surface 11b are all exposed, the side of the inner ring portion 11 facing the host, the side facing the central hole of the inner liner 1, and the side away from the host are all exposed. At this time, the side of the package 2 facing the host can be flush with the first annular exposed surface 11a, and the side of the package 2 away from the host can be flush with the second annular exposed surface 11b. This effectively prevents the package 2 from overflowing during the injection molding process, improves the injection molding quality of the package 2, thereby effectively improving the yield of the pallet assembly 10, and simplifies the injection molding process of the package 2, reducing costs.

[0090] In some embodiments, along a first direction, there is a height difference between the surface of the outer ring portion 12 facing the host and the surface of the inner ring portion 11 facing the host, and the surface of the outer ring portion 12 away from the host is flush with or has a height difference with the surface of the inner ring portion 11 facing the host.

[0091] Therefore, the inner liner 1 can be a T-shaped structure or an L-shaped structure, so that the inner liner 1 has high structural strength while also having a relatively simple structure, which is easy to implement and reduces costs.

[0092] In some embodiments, such as Figures 9-14 As shown, the outer ring portion 12 has a first edge 121 and a second edge 122 opposite to the surface of the host. The first edge 121 is connected to the inner ring portion 11. The outer ring portion 12 is at least partially inclined opposite to the surface of the host so that the second edge 122 is close to the first surface 1a relative to the first edge 121.

[0093] Therefore, while ensuring that the inner liner 1 has high structural strength, the outer ring portion 12 of the inner liner 1 is thinner and lighter along the first direction at the end away from the inner ring portion 11, which reduces the weight of the inner liner 1 and facilitates the thinner and lighter design of the pallet assembly 10.

[0094] The inclined portion of the outer ring 12 that faces away from the main unit can be an inclined plane or an inclined arc surface, and is not limited here.

[0095] Optionally, the width of one side of the inner liner 1 is 2.5 mm to 4.3 mm radially along the center hole of the inner liner 1. For example, Figure 11 , Figure 12 and Figure 14 The dimension shown in N is as follows.

[0096] Therefore, the inner liner 1 can have good structural strength while also having a smaller size and lighter weight, which is conducive to the thinner and lighter design of the tray assembly 10, and thus facilitates the thinner and lighter design of wearable devices.

[0097] It should be explained that the single-side width of the inner liner 1 mentioned above refers to the difference between the distance between the central hole of the annular inner liner 1 and the inner circumferential surface of the inner liner 1, and the distance between the central hole of the inner liner 1 and the outer circumferential surface of the inner liner 1. For example, when the inner liner 1 is an annular structure, the single-side width can be the difference between the outer radius and the inner radius of the inner liner 1.

[0098] When the width of one side of the inner liner 1 is less than 2.5mm, the size of the inner liner 1 can be made smaller, which is conducive to the thinner and lighter design of the pallet assembly 10. However, the structural strength of the smaller inner liner 1 is limited, which means that the inner liner 1 is still prone to deformation and breakage when subjected to greater force.

[0099] When the width of one side of the inner liner 1 is greater than 4.3mm, although the structural strength of the inner liner 1 is better, the larger size of the inner liner 1 will result in a larger size of the pallet assembly 10, which is not conducive to the thinner and lighter design of the pallet assembly 10.

[0100] The width of one side of the inner lining 1 can be any size such as 2.5mm, 3mm, 3.2mm, 4.3mm, etc., and is not limited here.

[0101] This application also provides a wearable device, such as... Figure 15 As shown, the device includes a host 20 and a tray assembly 10 as described in any of the above embodiments, wherein the host 20 is rotatably mounted on the tray assembly 10.

[0102] In this embodiment, the tray assembly 10 in the wearable device 100 is the tray assembly 10 described in any of the above embodiments. Therefore, in this wearable device 100, the inner liner 1 of the tray assembly 10 can have high structural strength, making the tray assembly 10 less prone to deformation or breakage during use. This makes the main unit 20 less likely to come apart due to deformation or breakage of the tray assembly 10, thus improving the user's experience with the wearable device 100.

[0103] Furthermore, the tray assembly 10 in the wearable device 100 is the tray assembly 10 described in any of the above embodiments. Therefore, the wearable device 100 can produce the same or similar beneficial effects as the tray assembly 10 described in any of the above embodiments, which will not be described in detail here.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
