Description

Technical Field

[0001] The utility model relates to the field of touch technology, and in particular to a touch mechanism and a near-eye display device. Background Art

[0002] Near-eye display devices such as augmented reality (AR) glasses and virtual reality (VR) glasses are usually equipped with a touch mechanism, and users can interact with the near-eye display device by touching the touch mechanism.

[0003] In the prior art, a touch mechanism includes a housing and a sensing element disposed inside the housing. When a user slides or clicks on the outer surface of the housing in a touch area corresponding to the sensing element, the sensing element senses the user touching the touch area. The near-eye display device then determines the user's operation based on the sensing result and executes the corresponding instruction, thus achieving touch control. However, because the outer surface of the housing is typically smooth, users can easily and unintentionally touch areas outside the touch area when sliding or clicking, resulting in the sensing element being unable to sense the user's relevant operation. Consequently, the near-eye display device is unable to obtain the user's touch location and accurately determine whether the user is performing a relevant operation. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1 and Figure 2 The present invention provides a touch mechanism for use in a near-eye display device. For example, the near-eye display device may include AR glasses, VR glasses, AR helmets, VR helmets, and the like.

[0039] like Figure 1 and Figure 2 As shown, the touch mechanism includes a housing 10 and a sensing element 20, including a first housing 11 and a second housing 12. The second housing 12 is disposed on one side of the first housing 11, and a receiving cavity 13 is formed between the second housing 12 and the first housing 11. The sensing element 20 is located in the receiving cavity 13 and is disposed on the second housing 12. The outer surface of the second housing 12, away from the receiving cavity 13, has a touch area 121 corresponding to the sensing element 20. The outer periphery of the touch area 121 at least partially forms a first guide structure 121a.

[0040] The touch mechanism of this embodiment comprises a housing 10 with a cavity 13. A sensing element 20 is located within the cavity 13 and connected to the second housing 20. The outer surface of the second housing 20, away from the cavity 13, has a touch area 121 for user touch. The touch area 121 corresponds to the sensing element 20, and when a user touches the touch area 121, the sensing element 20 senses the touch. By forming a first guide structure 121a at least partially around the periphery of the touch area 121, when the user touches the first guide structure 121a and the tactile sensation changes, it indicates that a part of the user's body, such as a finger, is currently touching a position near the edge of the touch area 121. This guide guides the user to operate within the touch area 121, preventing the user from operating in the non-touch area 122 beyond the touch area 121, thereby ensuring that the sensing element 20 can sense the user's operation.

[0041] It is worth noting that the first shell 11 and the second shell 12 can be provided as a whole, or the first shell 11 and the second shell 12 can be provided as separate bodies. The first shell 11 and the second shell 12 are provided as separate bodies, and the first shell 11 and the second shell 12 can be connected by fasteners, or by snap fastening or gluing.

[0042] In some embodiments, the near-eye display device is AR glasses or VR glasses, and the near-eye display device includes temples and a frame, and the temples are connected to the frame.

[0043] Exemplarily, the temple includes the shell 10 described above. When the touch mechanism is in the wearing state, the touch area 121 is located on the side of the second shell 12 away from the face, or the touch area 121 is located on the side of the second shell 12 along the direction of gravity.

[0044] For example, Figure 2 As shown, the second shell 12 is recessed in a direction away from the first shell, so that a receiving cavity 13 is formed between the first shell 11 and the second shell 12. When the user wears AR glasses or VR glasses, the first shell 11 can be set close to the face and the second shell 12 can be set away from the face. Figure 2 As shown in FIG, the touch area 121 is disposed on the bottom surface of the receiving groove, and the touch area 121 can be Figure 1 As shown in FIG, the touch area 121 is located on the side of the second housing 12 away from the first housing 11, that is, on the side of the second housing 12 away from the face. Alternatively, the sensing element 20 can be located on the upper side of the receiving groove along the direction of gravity, and the touch area 121 can be located on the upper side of the second housing 12 along the direction of gravity.

[0045] Exemplarily, the frame includes the shell 10 described above, and when the touch mechanism is in the wearing state, the touch area 121 is located on one side of the second shell 12 along the direction of gravity.

[0046] For example, the second shell 12 is recessed in a direction away from the first shell 11 so that a accommodating cavity 13 is formed between the first shell 11 and the second shell 12. When the user wears AR glasses or VR glasses, the second shell 12 can be set close to the face and the first shell 11 can be set away from the face. The sensing element 20 can be set on the upper side of the accommodating groove along the direction of gravity, and the touch area 121 can be located on the upper side of the second shell 12 along the direction of gravity, so that the user can touch the touch area to achieve touch.

[0047] For example, the user may touch the touch area 121 and perform a sliding or clicking operation on the touch area 121 .

[0048] For example, when the touch mechanism is applied to a near-eye display device, the sensing element 20 senses the user touching the touch area 121 and transmits the touch signal to the processing mechanism of the near-eye display device. The processing mechanism processes the touch signal to identify the user's operation and executes a program corresponding to the user's operation.

[0049] Optionally, the sensing element 20 includes a capacitive sensing element.

[0050] Optionally, the first guide structure 121 a is formed integrally with the second shell 12 by injection molding, or the first guide structure 121 a is formed by machining on the second shell 12 .

[0051] Exemplarily, the first guiding structure includes a protrusion or a groove.

[0052] like Figure 3 As shown, in some embodiments, at least a portion of the periphery of the touch area 121 protrudes in a direction away from the sensing element 20 to form a first guide structure 121a. Alternatively, at least a portion of the periphery of the touch area 121 is recessed in a direction toward the sensing element 20 to form the first guide structure 121a. It can be understood that the at least partial protrusion or recess of the periphery of the touch area 121 to form the first guide structure 121a creates a significantly varying height difference at at least a portion of the periphery of the touch area 121. When a user touches the first guide structure 121a and senses the height change of the outer surface of the second shell 12, it indicates to the user that they are currently touching a position near the boundary of the touch area 121, guiding the user to operate within the touch area 121. In addition, the first guide structure 121a is formed by the protrusion or recess of the outer surface of the second shell 12, which helps to simplify the manufacturing process and ensure the structural strength of the first guide structure 121a.

[0053] For example, Figure 3 As shown in FIG. 1A , the touch area 121 may protrude as a whole in a direction away from the sensing element 20 to form a first guide structure 121a. Alternatively, as shown in FIG. Figure 3 As shown in FIG. 1B , the touch area 121 may be entirely recessed toward the direction close to the sensing element 20 to form a first guiding structure 121 a .

[0054] For example, Figure 4 As shown in Figures (A), (C) and (D) of FIG, the outer periphery of the touch area 121 is formed with a protruding structure in a direction away from the sensing element 20, thereby forming a first guiding structure 121a. Alternatively, as Figure 4 Figure (B) and Figure 4 As shown in FIG. 8 (E), a concave structure is formed in the outer periphery of the touch area 121 toward the direction close to the sensing element 20 , thereby forming a first guiding structure 121 a .

[0055] In some embodiments, the first guiding structure 121 a is spaced apart from the non-touch area 122 .

[0056] For example, Figure 4 As shown in Figures (C), (D) and (E) in the figure, the first guide structure 121a is spaced apart from the non-touch area 122, which helps to ensure that when the user touches the first guide structure 121 and feels the height change of the outer surface of the second shell 12, the user's fingers or other body parts are still within the range of the touch area 121, playing the role of early guidance and reserving reaction time and operation space for the user.

[0057] In some embodiments, the sensing element 20 includes a sensing portion 21 and an electrical connection portion 22 connected to the sensing portion 21. The sensing portion 21 extends along a first direction, and the touch area 121 is disposed corresponding to the sensing portion 21. There are at least two first guide structures 121a, spaced apart from each other, with their projections onto the sensing portion 21 located at opposite ends of the sensing portion 21 along the first direction. The electrical connection portion 22 is electrically connected to the sensing portion 21 and a predetermined component (not shown). When the touch mechanism is applied to a near-eye display device, the predetermined component may be a controller of the near-eye display device. It is understood that forming first guide structures 121a on either side of the touch area 121 along the first direction, with the projections of the two first guide structures 121a onto the sensing portion 21 located at opposite ends of the sensing portion 21 along the first direction, guides the user to touch the touch area 121a between the two first guide structures 121a. This helps ensure that the user's operation is sensed by the sensing element 20 and improves the success rate of touch control.

[0058] For example, the first direction may be Figures 1 to 4 The X direction is shown in FIG.

[0059] For example, one or more locations on the periphery of the touch area 121 may be convex or concave relative to the first sub-area 1211 to form one or more first guiding structures 121 a.

[0060] For example, the user may touch the first guide structure 121 a before performing an operation, and after confirming the boundary position of the touch area 121 , perform an operation between the two first guide structures 121 a .

[0061] Furthermore, the two first guiding structures 121 a are correspondingly arranged along the first direction, that is, along the first direction, the projection of one first guiding structure 121 a is at least partially located on the other first guiding structure 121 a.

[0062] In some embodiments, both first guide structures 121a extend along the first direction. It is understandable that the first guide structures 121a extend along the first direction so that the user can sense the first guide structures 121a and avoid skipping the first guide structures 121a during touch operations.

[0063] In some embodiments, the number of the first guide structures 121a is an even number, and the even number of first guide structures 121a are symmetrically distributed at opposite ends of the touch area 121 in the first direction. In this way, the user is guided to perform touch operations in the range between the symmetrically distributed first guide structures 121a, thereby improving the success rate of the touch operation.

[0064] In some embodiments, the middle of the touch area at least partially forms a second guide structure 121b. It is understandable that the second guide structure 121b is located in the middle of the touch area 121 to guide the user to operate in the middle of the touch area 121 and improve the touch success rate.

[0065] For example, the user may perform an operation after sensing the second guide structure 121 b.

[0066] Illustratively, the second guiding structure 121 b includes a protrusion or a groove.

[0067] Furthermore, if Figure 3-4 As shown, at least a portion of the middle portion of the touch area 121 protrudes in a direction away from the sensing element 20 to form a second guide structure 121b, or at least a portion of the middle portion of the touch area 121 is recessed in a direction toward the sensing element 20 to form the second guide structure 121b. It will be appreciated that the protrusion or recessed portion of the middle portion of the touch area 121 to form the second guide structure 121b creates a significant height difference in at least a portion of the middle portion of the touch area 121. This indicates to the user that they are currently touching the middle portion of the touch area 121 when the user touches the second guide structure 121b and senses the height change of the outer surface of the second housing 12. This indicates to the user that they are currently touching the middle portion of the touch area 121, guiding the user to operate in the middle portion of the touch area 121, thereby improving the success rate of touch operations.

[0068] In some embodiments, such as Figure 4As shown, the touch area 121 extends along a first direction, and at least one first guide structure 121a is formed at opposite ends of the touch area 121 along the first direction. The second guide structure 121b is located between the two first guide structures 121a. As can be understood, the touch area 121 extends along the first direction to facilitate user sliding operations on the touch area 121 along the first direction. The second guide structure 121b is located between the two first guide structures 121a. Thus, the second guide structure 121b guides the user in sliding the touch area 121 along the first direction, while the two first guide structures 121a guide the user to determine the boundaries of the touch area 121, preventing the user from sliding beyond the range of the touch area 121 and affecting the success rate of touch.

[0069] In an optional embodiment, the second guide structure 121 b extends along the first direction, and the user can slide along the second guide structure 121 b in the touch area 121 to implement a sliding operation along the first direction.

[0070] Specifically, the two first guiding structures 121a are located on the extension line of the second guiding structure 121b, that is, along the first direction, the second guiding structure 121b and the first guiding structures 121a on both sides thereof are correspondingly arranged.

[0071] In another optional embodiment, a plurality of second guide structures 121 b are sequentially arranged along the first direction, and the user can slide over the plurality of second guide structures 121 b sequentially in the touch area 121 to implement a sliding operation along the first direction.

[0072] In some embodiments, the first guide structure 121a and the second guide structure 121b both include protrusions; alternatively, the first guide structure 121a and the second guide structure 121b both include grooves; alternatively, the first guide structure 121a includes a protrusion and the second guide structure 121b includes a groove; alternatively, the first guide structure 121a includes a groove and the second guide structure 121b includes a protrusion. It is understood that the configuration of the first guide structure 121a and the second guide structure 121b is relatively flexible and can be adjusted according to actual needs.

[0073] For example, Figure 3 As shown in FIG. 1A , the entire touch area 121 protrudes to form a first guide structure 121 a , and the middle portion of the touch area 121 can further protrude to form a second guide structure 121 b .

[0074] Preferably, both the first guide structure 121a and the second guide structure 121b include protrusions, which makes it easier for the user to sense the first guide structure 121a and the second guide structure 121b, and when the user performs a sliding operation in the touch area 121, when the user slides and touches the first guide structure 121a, the first guide structure 121a can block the user's sliding operation, preventing the user from sliding too fast and skipping the first guide structure 121a, thereby ensuring that the first guide structure 121a can play a guiding role.

[0075] Furthermore, the protrusion includes at least one of the following: an elliptical protrusion, a circular protrusion, a strip-shaped protrusion, a polygonal protrusion, and an annular protrusion. The groove includes at least one of the following: an elliptical groove, a circular groove, a strip-shaped groove, a polygonal groove, and an annular groove. It is understood that the shape of the protrusion or groove can be elliptical, circular, strip-shaped, polygonal, or annular. The shape of the protrusion or groove is relatively flexible and can be adjusted according to actual needs.

[0076] In some embodiments, the second guide structure 121 b is different from the first guide structure 121 a so that a user can distinguish the second guide structure 121 b from the first guide structure 121 a when touching the second guide structure 121 b .

[0077] For example, the difference between the first guide structure 121a and the second guide structure 121b may be manifested in that the first guide structure 121a and the second guide structure 121b have different shapes and / or sizes, for example Figure 1 As shown, the second guide structure 121b and the first guide structure 121a have different lengths along the X direction. The difference between the first guide structure 121a and the second guide structure 121b can also be manifested by the difference in the height of the protrusion of the first guide structure 121a and the height of the protrusion of the second guide structure 121b from the first side to the second side, or the difference in the depth of the groove of the first guide structure 121a and the depth of the groove of the second guide structure 121b. The difference between the first guide structure 121a and the second guide structure 121b can also be manifested by one of the first guide structure 121a and the second guide structure 121b being a protrusion and the other being a groove.

[0078] The present invention also provides a near-eye display device including the touch mechanism described above. It is understood that the near-eye display device including the touch mechanism described above also has all of its technical effects, namely, it can guide the user to operate within the touch area 121 and prevent the user from operating in the non-touch area 122 outside the touch area 121, thereby ensuring that the sensing element 20 can sense the user's operation.

[0079] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
