Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to display components and devices with touch springs. Background Technology

[0002] In related technologies, many home appliances use touch buttons instead of mechanical buttons in human-computer interaction interfaces. Touch buttons are implemented through touch springs. When a user touches the interaction panel, a capacitor is formed between the touch spring and the user. The controller detects the electrical signal of this capacitor to control the start or stop of the corresponding function.

[0003] In related technologies, the spring is in a free state before assembly and in a compressed state after assembly. During assembly, the direction of the force on the spring is different from the spring's axis, and there is an angle between these two directions, making the spring prone to tilting. Utility Model Content

[0004] In view of this, the present invention provides a display component and a device with a touch spring to solve the problem that the spring is prone to tilting during assembly.

[0005] In a first aspect, this utility model provides a display component, comprising:

[0006] Display panel;

[0007] A spring includes a first helical segment and a second helical segment connected together, wherein the pitch of the first helical segment is greater than the pitch of the second helical segment, and the end of the first helical segment away from the second helical segment is fixed to the display panel;

[0008] The display panel bracket is provided with a limiting structure, and the first spiral segment is limited by the limiting structure;

[0009] The display panel abuts against the end of the second spiral segment that is furthest from the first spiral segment.

[0010] Beneficial effects: Since the pitch of the first helical segment is greater than that of the second helical segment, the first helical segment is confined in the limiting structure of the display panel bracket and will not tilt even if subjected to a force in a direction different from the spring axis. The pitch of the second helical segment is smaller, so the second helical segment has greater stiffness and is less prone to tilting. Therefore, the spring of the display assembly is less prone to tilting during assembly.

[0011] In one alternative embodiment, the limiting structure is a limiting through hole, with at least a portion of the second spiral segment extending out of the limiting through hole.

[0012] Beneficial effects: Since the limiting structure is a limiting through hole, the first spiral segment is located in the limiting through hole. The limiting through hole limits the circumferential direction of the first spiral segment, which can prevent the first spiral segment from tilting when the spring is subjected to a force in a direction different from the spring axis. In addition, the second spiral segment has greater stiffness and is not easy to tilt. Therefore, the spring of this display component is not easy to tilt during assembly.

[0013] In one optional embodiment, the wire diameter of the spring is R0, the pitch of the first helical segment is P1, 4.5R0≤P1≤5.5R0, and the pitch of the second helical segment is P2, 1.05R0≤P2≤1.2R0.

[0014] Beneficial effects: Since the main deformation of the spring when compressed occurs in the first helical segment, with a pitch of P1 and 4.5R0≤P1≤5.5R0, it can be ensured that the first helical segment is easy to deform. The pitch of the second helical segment is P2 and 1.05R0≤P2≤1.2R0. The spring in the second helical segment is wound more tightly, thus ensuring that the free segment of the spring has sufficient stiffness to prevent tilting.

[0015] In one alternative implementation, 0.55mm ≤ R0 ≤ 0.65mm.

[0016] Beneficial effect: By keeping the spring wire diameter between 0.55mm and 0.65mm, it can be ensured that the spring has a sufficient number of effective coils when the free length of the spring is between 15.5mm and 16.5mm.

[0017] In one alternative implementation, the limiting structure is tilted.

[0018] Beneficial effects: Due to the inclined setting of the limiting structure, the spring is set in the limiting structure. Therefore, the axial direction of the spring is inclined. During assembly, when there is an angle between the assembly direction of the display panel bracket and the axial direction of the spring, the spring is prone to tilting, which will lead to inaccurate touch. By limiting the first helical segment in the limiting structure of the display panel bracket, it will not tilt even if it is subjected to a force in a different direction from the spring axis. The pitch of the second helical segment is smaller, so the stiffness of the second helical segment is greater and it is not easy to tilt. Therefore, the spring as a whole is not easy to tilt during assembly.

[0019] In one alternative implementation, the display panel support is tilted.

[0020] Beneficial effects: The tilted design of the display panel saves space and makes the appearance more aesthetically pleasing.

[0021] In one alternative implementation, the display panel includes a tilted region, and the second spiral segment abuts against the tilted region.

[0022] Beneficial effects: The display panel includes a tilted area, and the second helical segment abuts against this tilted area. During assembly, the display panel abuts against the free end of the spring, and the display panel bracket is assembled vertically. Therefore, there is an angle between the direction of force on the spring and its axial direction, making the spring prone to tilting. By confining the first helical segment within the limiting structure of the display panel bracket, it will not tilt even when subjected to a force in a direction different from the spring's axial direction. Furthermore, the second helical segment has a smaller pitch, resulting in greater stiffness and making it less prone to tilting. Therefore, the entire spring is less likely to tilt during assembly. Additionally, the tilted area of ​​the display panel allows users to see it without looking down, making it easier to operate and view the display results.

[0023] In one alternative embodiment, the display assembly further includes a controller bracket, which is fixedly connected to the display panel and the display panel bracket.

[0024] Beneficial effects: The display assembly also includes a controller bracket, which is fixedly connected to the display panel and the display panel bracket. During assembly, the controller bracket can be connected to the display panel and the display panel bracket as one unit first, and then the integrated structure can be connected to the display panel, which can improve assembly efficiency.

[0025] In one alternative embodiment, the display assembly further includes a support ring, the display panel is fixedly connected to the support ring, and the controller bracket is fixedly connected to the support ring.

[0026] Beneficial effects: The support ring provides support, the display panel is fixedly connected to the support ring, and the controller bracket is fixedly connected to the support ring. During assembly, the controller bracket is connected to the display panel and the display panel bracket as one unit, and then the integrated structure is fixedly connected to the support ring. After the controller bracket and the support ring are assembled in place, the spring is compressed, and the entire display assembly is completed.

[0027] In one alternative implementation, the deformation of the spring after assembly is Δh, where 0.5mm ≤ Δh ≤ 1.5mm.

[0028] Beneficial effects: By keeping the spring deformation Δh between 0.5mm and 1.5mm, it can be ensured that the free end of the spring can fit tightly against the inside of the display panel when assembled, and the limiting structure will not fail due to the excessive free length of the spring, thus preventing the spring from tilting.

[0029] Secondly, this utility model also provides a device with a touch spring, comprising:

[0030] The aforementioned display component.

[0031] Beneficial effects: Because the pitch of the first helical segment is greater than that of the second helical segment, the first helical segment is confined within the limiting structure of the display panel bracket and will not tilt even when subjected to a force in a direction different from the spring axis. The second helical segment has a smaller pitch, resulting in greater stiffness and making it less prone to tilting. Therefore, the spring in this device with a touch spring is less likely to tilt during assembly. After assembly, the display panel abuts against the end of the second helical segment furthest from the first helical segment. The area on the display panel corresponding to the touch spring constitutes the touch area. When the user touches the display panel, a capacitor is formed with the spring, and the controller detects the electrical signal of this capacitor to control the activation or deactivation of the corresponding function.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] In related technologies, many home appliances use touch buttons instead of mechanical buttons in human-computer interaction interfaces. Touch buttons are implemented through touch springs. When a user touches the interaction panel, a capacitor is formed between the touch spring and the user. The controller detects the electrical signal of this capacitor to control the start or stop of the corresponding function.

[0044] In related technologies, the spring is in a free state before assembly and in a compressed state after assembly. During assembly, the direction of the force on the spring is different from the spring's axis, and there is an angle between these two directions, making the spring prone to tilting.

[0045] Specifically, in the case of a tilted display panel, before assembly, one end of the spring is welded to the display panel, while the other end is in a free state. During assembly, the controller bracket, the display panel, and the display panel bracket are assembled with the support ring from bottom to top. The other end of the spring will abut against the display panel. Therefore, the direction of the force on the spring is different from the spring's axis, and there is an angle between these two directions, so the spring is prone to tilting.

[0046] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, a display component is provided, including a display panel 1, a spring 2, a display panel bracket 3, and a display panel 7.

[0048] The spring 2 includes a first helical segment 201 and a second helical segment 202 connected together. The pitch of the first helical segment 201 is greater than the pitch of the second helical segment 202. The end of the first helical segment 201 away from the second helical segment 202 is fixed to the display panel 1. The display panel bracket 3 is provided with a limiting structure, and the first helical segment 201 is limited in the limiting structure. The display panel 7 abuts against the end of the second helical segment 202 away from the first helical segment 201.

[0049] In this embodiment, since the pitch of the first helical segment 201 is greater than the pitch of the second helical segment 202, the first helical segment 201 is confined in the limiting structure of the display panel bracket 3 and will not tilt even if subjected to a force in a direction different from the axial direction of the spring 2. The pitch of the second helical segment 202 is smaller, so the second helical segment 202 has greater stiffness and is not easy to tilt. Therefore, the spring 2 of the display assembly is not easy to tilt during assembly.

[0050] After assembly, the display panel 7 abuts against the end of the second spiral segment 202 away from the first spiral segment 201. The area on the display panel 7 corresponding to the touch spring constitutes the touch area. When the user touches the display panel 7, it forms a capacitor with the spring 2. The controller detects the electrical signal of the capacitor to control the start and stop of the corresponding function.

[0051] In one specific embodiment, the end of the first helical segment 201 away from the second helical segment 202 is welded to the display panel 1.

[0052] In one specific embodiment, in the free state, the total height of the effective coils of spring 2 is denoted as h, the height of the effective coils in the large pitch region is denoted as h1, and the height of the effective coils in the small pitch region is denoted as h2. When assembled in place, the compression of spring 2 is denoted as Δh, and the total height of the effective coils of spring 2 is denoted as h. ′ The effective number of turns in the large pitch region is denoted as h. ′ 1. The effective number of turns in the small-pitch region is denoted as h. ′ 2.

[0053] Then we have:

[0054] In a free state:

[0055] h = h1 + h2,

[0056] When assembled in place:

[0057] h ′ =h ′ 1+h ′ 2,

[0058] h ′ =h-Δh,

[0059] h ′ 1≈h1+Δh,

[0060] h ′ 2≈h2.

[0061] Therefore, the deformation of the first helical segment 201 is approximately equal to the overall deformation of the spring 2. The first helical segment 201 is confined in the limiting structure of the display panel bracket 3, and will not tilt even if subjected to a force in a direction different from the axis of the spring 2. The second helical segment 202 does not deform much and has greater stiffness, so it is not easy to tilt.

[0062] In one specific embodiment, the spring 2 is formed by winding steel wire, and the first helical segment 201 and the second helical segment 202 are integral structures formed by winding.

[0063] In one embodiment, the limiting structure is a limiting through hole 301, with at least a portion of the second spiral segment 202 extending out of the limiting through hole 301.

[0064] In this embodiment, since the limiting structure is a limiting through hole 301, the first spiral segment 201 is located in the limiting through hole 301. The limiting through hole 301 limits the circumferential direction of the first spiral segment 201, which can prevent the first spiral segment 201 from tilting when the spring 2 is subjected to a force in a direction different from the axial direction of the spring 2. In addition, the second spiral segment 202 has greater stiffness and is not easy to tilt. Therefore, the spring 2 of the display component is not easy to tilt during assembly.

[0065] In one embodiment not shown in the figure, the limiting structure may be a plurality of limiting posts spaced apart along the circumference of the spring 2, which limit the circumference of the first helical segment 201.

[0066] In another embodiment not shown in the figure, the limiting structure may include a limiting post, with the first helical segment 201 sleeved outside the limiting post. This can also prevent the first helical segment 201 from tilting when the spring 2 is subjected to a force in a direction different from the axial direction of the spring 2. Furthermore, the second helical segment 202 has greater stiffness and is less prone to tilting, thus making it less likely for the entire spring 2 to tilt during assembly.

[0067] In one embodiment, the wire diameter of spring 2 is R0, the pitch of the first helical segment 201 is P1, 4.5R0≤P1≤5.5R0, and the pitch of the second helical segment 202 is P2, 1.05R0≤P2≤1.2R0.

[0068] In this embodiment, since the main deformation of the spring 2 when compressed occurs in the first helical segment 201, the pitch of the first helical segment 201 is P1, 4.5R0≤P1≤5.5R0, which ensures that the first helical segment 201 is easy to deform. The pitch of the second helical segment 202 is P2, 1.05R0≤P2≤1.2R0. The spring 2 in the second helical segment 202 is wound more tightly, which ensures that the free segment of the spring 2 has sufficient stiffness to prevent tilting.

[0069] In one specific embodiment, P1 = 4.5R0.

[0070] In one specific embodiment, P1 = 5R0.

[0071] In one specific embodiment, P1 = 5.5R0.

[0072] In one specific embodiment, P2 = 1.05R0.

[0073] In one specific embodiment, P2 = 1.1R0.

[0074] In one specific embodiment, P2 = 1.2R0.

[0075] In one embodiment, 0.55mm ≤ R0 ≤ 0.65mm.

[0076] In this embodiment, by making the wire diameter of spring 2 between 0.55mm and 0.65mm, it can be ensured that when the free length of spring 2 is between 15.5mm and 16.5mm, spring 2 has a sufficient number of effective coils.

[0077] In one specific embodiment, the wire diameter of spring 2 is 0.55 mm.

[0078] In one specific embodiment, the wire diameter of spring 2 is 0.6 mm.

[0079] In one specific embodiment, the wire diameter of spring 2 is 0.65 mm.

[0080] It should be noted that spring 2 is formed by winding steel wire, and the wire diameter of spring 2 refers to the diameter of the steel wire.

[0081] In one embodiment, the limiting structure is tilted.

[0082] In this embodiment, because the limiting structure is tilted, the spring 2 is set in the limiting structure. Therefore, the axial direction of the spring 2 is tilted. During assembly, when there is an angle between the assembly direction of the display panel bracket 3 and the axial direction of the spring 2, the spring 2 is prone to tilting, which may lead to inaccurate touch. By limiting the first helical segment 201 in the limiting structure of the display panel bracket 3, it will not tilt even if it is subjected to a force in a direction different from the axial direction of the spring 2. The pitch of the second helical segment 202 is small, so the stiffness of the second helical segment 202 is large and it is not easy to tilt. Therefore, the spring 2 as a whole is not easy to tilt during assembly.

[0083] In one embodiment, the display panel bracket 3 is tilted.

[0084] In this embodiment, the tilted arrangement of the display panel bracket 3 saves space and makes the appearance more aesthetically pleasing.

[0085] In one embodiment, the display panel 7 includes a tilted region, and the second spiral segment 202 abuts against the tilted region.

[0086] In this embodiment, the display panel 7 includes an inclined region, and the second helical segment 202 abuts against the inclined region. During assembly, the display panel 7 abuts against the free end of the spring 2, and the display panel bracket 3 is assembled in the vertical direction. Therefore, there is an angle between the force direction of the spring 2 and the axial direction of the spring 2, making the spring 2 prone to tilting. By confining the first helical segment 201 within the limiting structure of the display panel bracket 3, it will not tilt even when subjected to a force in a direction different from the axial direction of the spring 2. The second helical segment 202 has a smaller pitch, thus its stiffness is greater and it is less prone to tilting. Therefore, the spring 2 as a whole is less prone to tilting during assembly. In addition, the display panel 7 includes an inclined region, allowing the user to see the display panel 7 without looking down, making it easier for the user to operate the display panel 7 and view the display results.

[0087] In one embodiment, the display assembly further includes a controller bracket 4, which is fixedly connected to the display panel 1 and the display panel bracket 3.

[0088] In this embodiment, the display assembly also includes a controller bracket 4, which is fixedly connected to the display panel 1 and the display panel bracket 3. During assembly, the controller bracket 4 can be connected to the display panel 1 and the display panel bracket 3 as one unit first, and then the integrated structure can be connected to the display panel 7, which can improve assembly efficiency.

[0089] In one embodiment, the controller bracket 4 is provided with a first through hole, the display panel 1 is provided with a corresponding second through hole, the display panel bracket 3 is provided with a corresponding first screw hole, and the first screw 5 passes through the first through hole and the second through hole and is fixed in the first screw hole.

[0090] In this embodiment, the controller bracket 4 is provided with a first through hole, the display panel 1 is provided with a corresponding second through hole, and the display panel bracket 3 is provided with a corresponding first screw hole. The first screw 5 passes through the first through hole and the second through hole and is fixed in the first screw hole. Only one first screw 5 is needed to connect the controller bracket 4, the display panel 1, and the display panel bracket 3 into one unit, which can improve assembly efficiency.

[0091] In one embodiment not shown in the figure, the display panel 1 can be snapped into the display panel bracket 3, and the display panel bracket 3 can be screwed into the controller bracket 4.

[0092] In another embodiment not shown in the figure, the display panel 1 can be screwed to the display panel bracket 3, and the display panel bracket 3 can be screwed to the controller bracket 4.

[0093] In another embodiment not shown in the figure, the display panel 1 can be snapped onto the controller bracket 4, and the display panel bracket 3 can be screwed onto the controller bracket 4.

[0094] In one embodiment, the display component further includes a support ring 6, the display panel 7 is fixedly connected to the support ring 6, and the controller bracket 4 is fixedly connected to the support ring 6.

[0095] In this embodiment, the support ring 6 provides support, the display panel 7 is fixedly connected to the support ring 6, and the controller bracket 4 is fixedly connected to the support ring 6. During assembly, the controller bracket 4 is connected to the display panel 1 and the display panel bracket 3 as a whole, and then the structure after being connected as a whole is fixedly connected to the support ring 6. After the controller bracket 4 and the support ring 6 are assembled in place, the spring 2 is compressed, and the entire display assembly is completed.

[0096] In one specific embodiment, the display panel 7 can be fixed to the support ring 6 by adhesive or clips.

[0097] In one specific embodiment, after the controller bracket 4 is integrated with the display panel 1 and the display panel bracket 3, the integrated structure is assembled vertically. When the controller bracket 4 abuts against the support ring 6, the controller bracket 4 is in place, and then the controller bracket 4 and the support ring 6 are fixedly connected. Since the display panel 7 includes an inclined area, and the display panel bracket 3 abuts against the inclined area, during assembly, the display panel 7 abuts against the free end of the spring 2. The controller bracket 4 carries the display panel bracket 3 and is assembled vertically. Therefore, there is an angle between the force direction of the spring 2 and the axial direction of the spring 2, and the spring 2 is prone to tilting. By limiting the first helical segment 201 in the limiting structure of the display panel bracket 3, it will not tilt even if subjected to a force in a direction different from the axial direction of the spring 2. The second helical segment 202 has a smaller pitch, so the second helical segment 202 has greater stiffness and is not prone to tilting. Therefore, the spring 2 as a whole is not prone to tilting during assembly.

[0098] In one embodiment, the display panel 7 is connected to the support ring 6 by a second screw 8.

[0099] In this embodiment, the display panel 7 and the support ring 6 are connected by a second screw 8, which can ensure the stability of the connection between the display panel 7 and the support ring 6.

[0100] In one specific embodiment, the support ring 6 is provided with a plurality of connecting holes spaced apart circumferentially, and the display panel 7 is provided with a plurality of second screw holes on the side facing the support ring 6. The second screw 8 passes through the connecting holes and is fixed in the second screw holes.

[0101] In one embodiment, the controller bracket 4 is connected to the support ring 6 by a third screw 9.

[0102] In this embodiment, the controller bracket 4 and the support ring 6 are connected by a third screw 9, which ensures a stable connection between the controller bracket 4 and the support ring 6, and at the same time allows the support ring 6 to drive the display panel 7 to apply sufficient pressure to the spring 2.

[0103] In one embodiment, the deformation of spring 2 after assembly is Δh, where 0.5mm≤Δh≤1.5mm.

[0104] In this embodiment, by making the deformation Δh of the spring 2 between 0.5mm and 1.5mm, it can be ensured that the free end of the spring 2 can be tightly attached to the inner side of the display panel 7 when it is assembled in place. On the other hand, the limiting effect of the limiting structure will not fail due to the excessive free length of the spring 2, thus preventing the spring 2 from tilting.

[0105] In one specific embodiment, when the controller bracket 4 abuts against the support ring 6, the distance between the inner sides of the display panel 1 and the display panel 7 is H, the free length of the spring 2 is h, and the deformation of the spring 2 is Δh = hH.

[0106] In one specific embodiment, the free length of the spring 2 is h, 15.5mm≤h≤16.5mm, and when assembled, the distance between the display panel 1 and the inner side of the display panel 7 is 15mm.

[0107] In one specific embodiment, the free length of spring 2 is 15.5 mm.

[0108] In one specific embodiment, the free length of spring 2 is 16 mm.

[0109] In one specific embodiment, the free length of spring 2 is 16.5 mm.

[0110] The assembly process of the display component provided in this embodiment is as follows: First, weld the end of the first helical segment 201 of the spring 2 away from the second helical segment 202 to the display panel 1; Second, align the positioning hole on the display panel bracket 3 with the spring 2, and use the first screw 5 to connect the display panel 1 and the display panel bracket 3 to the controller bracket 4; Third, use the third screw 9 to connect the support ring 6 to the display panel 7; Fourth, use the second screw 8 to connect the component (first component) formed by connecting the display panel 1, the display panel bracket 3 and the controller bracket 4 to the component (second component) formed by connecting the support ring 6 and the display panel 7 along the assembly direction.

[0111] In the fourth step of the assembly process, the first component and the second component are considered complete when the controller bracket 4 contacts the support ring 6. As the first component approaches the second component along the assembly direction, the free end of the spring 2 first contacts the inner side of the display panel 7. When the first component and the second component are in place, the spring 2 is under pressure. During the assembly process, the external force on the first component is in the same direction as the assembly and forms an angle with the axial direction of the spring 2. Therefore, the spring 2 bears a certain load in the radial direction and is prone to tilting. By dividing the spring 2 into a first helical segment 201 and a second helical segment 202, the first helical segment 201 is located entirely within the limiting through hole 301 of the display panel bracket 3. During assembly, it does not tilt due to the action of the limiting through hole 301, ensuring that the spring 2 has the normal function of a touch spring. The deformation of the second helical segment 202 under pressure is much smaller than that of the first helical segment 201. The tendency for lateral tilting between adjacent turns of the spring 2 is reduced, the overall bending resistance is improved, and the spring 2 does not tilt during assembly.

[0112] According to an embodiment of the present invention, another aspect provides a device with a touch spring, including the display component provided in the above embodiment.

[0113] In this embodiment, because the pitch of the first helical segment 201 is greater than that of the second helical segment 202, the first helical segment 201 is confined within the limiting structure of the display panel bracket 3 and will not tilt even when subjected to a force in a direction different from the axial direction of the spring 2. The second helical segment 202, with its smaller pitch, has greater stiffness and is less prone to tilting. Therefore, the spring 2 of this device with a touch spring is less likely to tilt during assembly. After assembly, the display panel 7 abuts against the end of the second helical segment 202 away from the first helical segment 201. The area on the display panel 7 corresponding to the touch spring constitutes a touch area. When the user touches the display panel 7, it forms a capacitor with the spring 2. The controller detects the electrical signal of this capacitor to control the start and stop of the corresponding function.

[0114] In one specific embodiment, the device with the touch spring is an electric kettle, a rice cooker, etc.

[0115] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
