Description

Wall switch control panel

Technical Field

The utility model relates to a switch panel, in particular to a wall switch control panel.

Background

With the development of smart home, various home devices gradually enter the life of users, and in order to control the various devices, a control function is inevitably required to be added on a wall switch control panel so as to adapt to more home devices, and the requirements of people cannot be met by the traditional three-key switch and four-key switch. In order to solve the problem, some designers propose a six-key and eight-key wall switch control panel, under the condition that the overall size of the wall switch control panel is fixed and limited, more keys mean that the size of the keys can be smaller, the layout of the keys can be more compact, and under the condition that the traditional multi-key switch can not give enough prompts to the keys, the memory burden of people is increased, and the accurate control of people is not facilitated.

In this case, the prior art proposes the concept of a wall switch control panel of a full touch display screen, which controls more smart home devices through a touch display screen having a multi-level display menu. The switch panel has the advantages that each page only displays a limited number of control keys, the identification is convenient, and meanwhile, a plurality of virtual control keys can be theoretically provided through software upgrading, so that the switch panel can be matched with a large number of household electronic equipment to the greatest extent.

As a modification of the wall switch control panel of the above-mentioned full touch display screen, a wall switch control panel of a two-in-one type having both physical control keys and a touch screen is also proposed to accommodate different control preferences (some people prefer to use the physical control keys). The panels often adopt a mode of respectively controlling a left-right separation or an up-down separation of the physical control keys and the touch screen, and only a few physical control keys correspond to the common switches, and the touch screen carries more control keys.

However, the two types of wall switch control panels with touch screens ignore an important problem, and the virtual keys provided by the touch screens bear more control functions, so that people are forced to intensively identify the control functions on the screens to control the control panels in most cases. However, in dim light or night environments, people can avoid a display screen that emits light in front view (even if the display mode is provided at night) or more prone to "blind operation" to control, and precise control at this time cannot be achieved or performs poorly.

Disclosure of Invention

In order to solve at least the problems that the prior art has more physical keys and memory is difficult, and the prior art mainly depends on a touch screen and is not suitable for blind operation. The embodiment of the utility model provides a wall switch control panel, which is characterized by comprising:

a central display element;

a plurality of control keys disposed about the central display element,

the central display element displays at least state information of the plurality of control keys, the plurality of control keys comprise main keys, and the plurality of control keys are distributed in a step shape along at least one direction gradually far away from the main keys.

In this embodiment of the utility model, the display element is centered and the control keys surround the display element, it is obvious that the idea of this configuration is to mainly provide control functions for a plurality of control keys, but the display of status information of the control keys by the central display element can facilitate the user to become familiar with the functions of each key at the beginning of use. Meanwhile, the step-shaped key distribution is provided, so that the later stage can not depend on the display of the display element, and the position difference of each key can be perceived through the 'section sense' when touching, so that the keys are identified. In fact, the display element of the present utility model is not required to be a touch screen, and a conventional display screen capable of displaying state information of control keys is only required, because the display element is mainly based on physical control keys.

The term "main key" refers to the most important function key or key with the highest frequency of use in the wall switch control panel.

In some embodiments, the primary key has a lowest height relative to other keys of the plurality of control keys relative to a mounting surface of the wall switch control panel on the wall, the plurality of control keys being distributed from the primary key in a stepped key profile with a gradual rise in height in at least one direction gradually away from the primary key. The height of the main key is lowest, and the stepped key distribution with gradually rising height is adopted, so that the main key is conveniently and accurately positioned, and the continuous height-changing tactile feedback which is easier to identify is provided on the hand feeling identification of other keys.

In some embodiments, among the plurality of control keys, any adjacent two control keys include a high key having a high height relative to the mounting surface and a low key having a low height relative to the mounting surface, the key surface of the high key extending toward the key surface of the low key beyond a junction line between the key body of the high key and the key body of the low key, and the maximum key stroke of the high key being smaller than a difference in height between the key surface of the high key and the key surface of the low key. The area of the operation key surface of the high key is further increased by means of the step design in which the key surface of the high key extends towards the key surface of the low key beyond the connection boundary between the key bodies of the high key, so that the operation key surface is beneficial to users.

Moreover, considering that the key surface of the high key is enlarged, when the user presses the edge portion of the key surface of the high key with force, compared with pressing the central portion of the high key, the maximum key stroke of the high key is triggered, and at this time, there is a risk that the edge portion abuts against the key surface of the low key to activate the low key by mistake, so that the maximum key of the high key is controlled to be smaller than the height difference between the high key and the low key, and the risk can be avoided.

In some embodiments, a light emitting element is disposed at a junction line between the key body of the high key and the key body of the low key. On the basis that the key surface of the high key extends beyond the boundary line between the key body of the high key and the key body of the low key, the light-emitting element is arranged at the boundary line, and on the basis that visual identification and attractive appearance of the key are realized through illumination, direct irradiation of the light-emitting element to human eyes is avoided through the key surface extension. In fact, when the light-emitting element is arranged at the junction line and the extended key of the high key is partially shielded from the light-emitting element, a specific shadow effect is also displayed, so that the concave-convex stepped feeling between the keys is further enhanced, stronger visual guidance of the keys is provided, and the user identification is facilitated.

In some embodiments, the wall switch control panel is a square panel, and the at least one direction includes a lateral direction and a longitudinal direction. The square panel is adopted, so that the conventional 86-box embedded hole can be better compatible, and a user can upgrade the existing wall switch control panel conveniently.

To meet the preferences of different users, in some embodiments, the wall switch control panel is a circular panel, and the at least one direction includes a clockwise direction and a counterclockwise direction.

In some embodiments, the main key is disposed at a lower corner of one side of the central display element, and the wall switch control panel further includes a sensor module at an upper corner of the other side of the central display element, the sensor module including: at least one of a distance proximity sensor, a capacitive touch sensor, and a light sensor. The sensor module is introduced, so that the use scene of the wall switch control panel is enriched, and the requirement of linkage control after more and more intelligent household devices are introduced in the future can be met. Furthermore, the arrangement of the sensor module "furthest" from the main key also avoids to some extent false activation of the sensor module when operating a common main key. The main key can be set as a home scene control key, and other keys in the plurality of control keys are home equipment control keys. The setting of the scene control keys simplifies the operation of the user, so that the user can control one or more household devices simultaneously by only controlling the scene control keys when needed.

In some embodiments, the wall switch control panel is further provided with fragrance components on the peripheral wall.

In some embodiments, the fragrance assembly is positioned on the back of the control key that is highest in height relative to the mounting surface. The applicant notes that after the switch is configured in a step-shaped manner, the space behind the control key with the highest mounting surface height is more abundant, and accessories such as aromatherapy can be additionally arranged, so that the function diversity and the thinness of the wall switch control panel are considered. In addition, more complex fragrance assemblies may be used in sufficient space, and the fragrance assembly in this embodiment includes a fragrance sheet holder, a heating element for heating the fragrance sheet holder, and an infrared correlation element for detecting the presence of fragrance sheets within the fragrance sheet holder. The applicant notes that the aromatherapy sheet support is in a heated high-temperature state, if a contact detection mode is adopted, heat can be possibly led into the detection element and the circuit board, and potential risks are further caused on other electronic devices on the circuit board, so that the non-contact infrared correlation element is adopted to detect the aromatherapy sheet in the aromatherapy sheet support, and the life of the wall switch control panel is prolonged.

In some embodiments, the wall switch control panel comprises a circuit board for carrying the central display element and the plurality of control keys, an opening for receiving the fragrance sheet holder and accommodating the heating element is arranged at the edge of the circuit board, the heating element is positioned in the opening and is electrically connected with the circuit board through leads, and the infrared correlation element is positioned at two sides of the opening and is arranged on the circuit board. The applicant has further reduced the thickness of the wall switch control panel by not having the heating element disposed on the circuit board but within an opening at the edge of the circuit board. Moreover, the heating element is positioned in the opening and is electrically connected with the circuit board through the lead wire, so that the heat conduction of the high-temperature heating element to the circuit board is reduced, and the electronic devices on the circuit board are prevented from being damaged in a long-term high-temperature environment. In some embodiments, at least one of an illumination lamp and a temperature/humidity sensor is further provided on a peripheral wall of the wall switch control panel, away from the fragrance assembly.

The embodiment of the utility model has the beneficial effects that: the utility model provides a control panel with a display element and a plurality of entity keys, wherein the entity keys bearing main control functions are distributed in a stepped mode according to a specific direction or directions, so that visual guidance can be provided for state information of surrounding keys when the display element is opened, and tactile guidance can be provided for the plurality of keys through the stepped distribution when the display element is closed or a user does not concentrate on the display element, and the distinction of the keys of the user is prompted. And the starting points of the step-shaped distribution are the main keys, so that a user can conveniently and accurately identify the main keys, and the wall switch control panel is particularly convenient for the user to activate and use in a dim light or night environment.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, a wall switch control panel according to an embodiment of the present utility model is provided, the wall switch control panel is square, and includes:

a central display element 11;

five control keys arranged around the central display element 11, including: a main key 120, a first key 121, a second key 122, a third key 123, a fourth key 124,

wherein the central display element 11 displays at least status information of five control keys, which are stepwise key-distributed starting from the main key 120 in lateral and longitudinal directions gradually away from said main key 120.

In fig. 1, the main key 120 is disposed at the lower left corner of the central display element 11, the first key 121 is laterally adjacent to the main key 120, the second key 122 is longitudinally adjacent to the main key 120, the third key 123 is laterally distant from the main key 120 and laterally adjacent to the first key 121, the fourth key 124 is longitudinally distant from the main key 120 and longitudinally adjacent to the second key 122, and the sensor module 13 is located at the upper right corner of the central display element 11. The sensor module 13 is vertically adjacent to the third key 123 and laterally adjacent to the fourth key 124, the sensor module 13 comprising: at least one of a distance proximity sensor, a capacitive touch sensor, and a light sensor.

In this embodiment, the main key 120 is a home scene control key, and the first key 121, the second key 122, the third key 123, and the fourth key 124 are home device control keys. Wherein the inner tube corresponds to the combined control state of different devices in each scene. The sensor module 13 provides more intelligent possibilities for the wall switch control panel, for example, providing a distance proximity sensor that can be used as a human sensor to activate a screen that lights up the central display element; setting a capacitive touch sensor, which is equivalent to additionally arranging a control key; the light sensor is arranged to coordinate with adjusting the display brightness of the central display element, etc. The cover plate of the sensor module 13 at the wall switch control panel part can be made of transparent or semitransparent materials such as glass, resin, acrylic and the like so as to facilitate the effective work of each sensor in the sensor module.

It should be noted that the above examples are only examples, and are not limited to the usage status thereof, and various sensors and combinations thereof may be relied on to provide various upgrade spaces for the control panel of the post wall switch.

In the embodiment shown in fig. 1, the display element is centered, and the overall size is not large (e.g., 1.3 inches), and more control functions are given to the physical control keys. In addition to the main key, four keys are provided. The arrangement of five keys gives consideration to the size and the number of keys, and is convenient to identify and memorize through more regular step distribution.

When the wall switch control panel is used as a bedside control panel, the left side or the right side lower corner can be selected according to the direction of the bedside to arrange the main keys, so that a user can easily access and control the wall switch control panel from the bed. In addition, the square panel has taken into account the installation size of traditional 86 boxes, does benefit to the user to the wall switch panel of the pre-cut hole in the current house to upgrade. Although five are illustrated in fig. 1 for the number of control keys and the sensor module 13 is provided at the top corner on the opposite side of the primary key 120 rather than the sixth key, it should be understood that the number and configuration herein are merely illustrative of the preferred embodiment and are not intended to limit the present utility model.

As shown in fig. 2A, another wall switch control panel according to an embodiment of the present utility model is a circular panel, including:

a central display element 11';

five control keys arranged around the central display element 11', including: the primary key 120', the first key 121', the second key 122', the third key 123', the fourth key 124',

wherein the central display element 11' displays at least the status information of five control keys, which are stepwise key-distributed starting from the main key 120' in clockwise and counter-clockwise directions gradually away from the main key 120 '.

In fig. 2A, the central display element 11' is circular, the main key 120' is disposed at the lower left corner of the central display element 11', and the sensor module 13' is disposed at the upper right corner of the central display element 11 '. The main key 120', the first key 121', the second key 122', the third key 123', and the fourth key 124' are of comparable size.

In this embodiment of the present utility model, since the stepped key distribution is provided, the position difference of each key can be perceived through the sense of the section when touching, and the stepped key distribution in the clockwise and counterclockwise directions is utilized to further strengthen the concave-convex stepped sense between each control key, provide stronger visual guidance of the keys, and facilitate the user recognition and memory.

As a variation, fig. 2B shows a schematic view of another circular wall switch control panel, comprising:

in fig. 2B, the central display element 11 "is square, the main key 120" is disposed at the lower left corner of the central display element 11", and the sensor module 13" is disposed at the upper right corner of the central display element 11 ". The first key 121", the second key 122", the third key 123", and the fourth key 124" are not uniform in size.

The difference between fig. 2B and fig. 2A is that the square display element 11 "can reduce the production cost more, and the wall control switch itself has the design element of" dome ", when being used with the chinese home, and better blends into the chinese home environment.

Further, with reference to fig. 3, 4 and 5, the structure of the wall switch control panel shown in fig. 1 can be more clearly disclosed. In the above-described figures, the main key 120 has the lowest height than other keys with respect to the mounting surface P of the wall switch control panel on the wall, the first key 121 and the third key 123 are arranged in a stepwise manner in which the heights of the keys gradually rise in a lateral direction gradually away from the main key 120, and the second key 122 and the fourth key 124 are arranged in a stepwise manner in which the heights of the keys gradually rise in a longitudinal direction gradually away from the main key 120.

In fig. 4, the second key 122 is higher than the adjacent main key 120, the key face of the second key 122 extends toward the key face of the main key 120 beyond the junction line 142 between the two key bodies, the fourth key 124 is higher than the adjacent second key 122, and the key face of the fourth key 124 extends toward the key face of the second key 122 beyond the junction line 144 between the two key bodies.

In fig. 5, the first key 121 is higher than the adjacent main key 120, the key surface of the first key 121 extends toward the key surface of the main key 120 beyond the junction line 141 between the two key bodies, the third key 123 is higher than the adjacent first key 121, and the key surface of the third key 123 extends toward the key surface of the first key 121 beyond the junction line 143 between the two key bodies.

In the utility model, the wall switch control panel is divided into a plurality of control keys, and the central display element occupies a part of area, so that the area of the operation key surface of each control key is relatively limited, and in order to further improve the area of the operation key surface of the control key, the area of the operation key surface of the high key is increased by virtue of the step-shaped design, so that the key surface of the high key can extend towards the key surface of the low key beyond the junction line of the key bodies of the two keys, thereby being beneficial to users.

Moreover, considering the increase of the key surface of the high key, when the user presses the edge portion of the key surface of the high key with force, compared with pressing the central portion of the high key, the maximum key stroke of the high key is triggered, and at this time, there is a risk that the edge portion abuts against the key surface of the low key to activate the low key by mistake, so that the maximum key program of the high key is controlled to be smaller than the height difference between the key surface of the high key and the key surface of the low key, and the risk can be avoided.

With further reference to fig. 3, the first key 121, the second key 122, and the central display element 11 have a uniform first height with respect to the mounting surface P, and the third key 123, the sensor module 13, and the fourth key 124 have a uniform second height with respect to the mounting surface P.

The utility model also reduces the memory burden of the user to the ladder touch sense as much as possible when providing the ladder type key recognition, and because the first key 121 and the second key 122 are already different in direction, the first key and the second key can be designed to be the same height as the central display element 11 to reduce the learning cost of the key touch sense, and the whole wall switch control panel is more harmonious and uniform in vision and does not cause visual confusion. Similarly, since the third key 123 and the fourth key 124 are already different in direction, they can be designed to have the same height as the sensor module 13, further enhancing the wall switch control panel to be more harmonious in visual uniformity.

Fig. 6A and 6B are schematic views of the wall switch control panel with the main body of the outer mounting bracket removed and the key caps of the central display element and control keys removed. The main body 51 includes a circuit board 41 for mounting a central display element, five control keys and a sensor module, and a frame 21 for carrying the circuit board 41, and light emitting elements 16 are disposed at junction lines 141, 142, 143, 144 between key bodies of two adjacent keys, where the light emitting elements are LED light beads. A temperature/humidity sensor 211 is also provided adjacent to the main key 120 at the lower left corner of the front surface of the circuit board 41, and an illumination lamp 212 is also provided directly below the back surface of the circuit board 41, facing away from the first key 121.

As an example, when a user uses the wall switch control panel late at night, for example, at night, when the eyes are just open from deep sleep, the adaptability to the light source is poor, and if the light source of the light emitting element is directly projected into the eyes of the user, discomfort is brought to the user. At this time, the first, second, third and fourth keys 121, 122, 123, 124 (as understood in conjunction with fig. 3) exceeding the boundary lines 141, 142, 143, 144 are used to realize visual recognition of the keys by the illumination of the light emitting element 16, and direct illumination of the light emitting element 16 to human eyes is avoided. In fact, when the light-emitting element is arranged at the junction line and the extended key is partially shielded from the light-emitting element, specific lighting and shadow (shadow) effects are also displayed, so that the concave-convex stepped feeling between the control keys is further enhanced, and stronger visual guidance of the keys is provided.

In cooperation with the main key 120 as a scene key, the main key is pressed for a long time, and scenes such as "rest", "reading", "guest", "movie" and the like are sequentially displayed on the central display element in a switching manner (the scene names can be user-defined), and the combined control states corresponding to different devices in each scene are additionally different in color (for example, red, yellow, blue and the like are displayed) of the light emitting element 16 arranged at the boundary line between the control key bodies in different scenes. Further, as can be seen in fig. 1 and 6, there is not necessarily only one button under each key cap, one button 1201 is under the main key 120, two buttons 1211 and 1212 are under the first key 121, two buttons 1221 and 1222 are under the second key 122, two buttons 1231 and 1232 are under the third key 123, and two buttons 1241 and 1242 are under the fourth key 124, and the first key 121, the second key 122, the third key 123 and the fourth key 124 implement two seesaw type pressing operations through the levers 151, 152, 153 and 154 on the frame 21, respectively. Although the main key 120 has only one button 1201, the lever 150 may be disposed upward for easy access by a user in a place such as a bed head, so that the user may slightly touch the lower portion of the main key 120 to realize the pressing control. In fig. 6, 9 kinds of control instructions are implemented on the basis of 1 main key and 4 control keys. Further, more control instructions can be realized without increasing the area of the wall switch control panel.

Fig. 7 shows a mounting bracket 31 for mating releasable connection with the frame 21. As can be seen in connection with fig. 6, the upper and lower parts of the frame 21 thereof are provided with snaps 210. Accordingly, the mounting bracket 31 in fig. 7 has a plurality of slots 310 that mate with the plurality of snaps 210 on the frame 21. The main body with the frame 21 can be mounted on the mounting bracket 31 by snap-connecting the plurality of snap-locks 210 on the frame 21 with the plurality of snap-lock grooves 310 in the mounting bracket 31. In actual use, the mounting bracket 31 may be first mounted at the position of the mounting hole of the corresponding embedded 86 box on the wall via the mounting hole 312 and the mounting hole 313, and then the main body 51 is fastened to the mounting bracket 31 by the fastener 210 and the fastening slot 310 that are matched with each other.

Fig. 8 shows the top of the wall control switch. In fig. 8, fragrance modules 42 are also provided on the peripheral wall at the top of the wall switch control panel. The fragrance module 42 is located at the back of the fourth button 124 having the highest height relative to the mounting surface P.

Fig. 9 shows the circuit board 41 when the fragrance sheet holder is not inserted into the wall switch control panel. In fig. 9, a central rectangular notch at the top edge of the circuit board 41 is an opening 424 for receiving a fragrance sheet holder (shown in fig. 10A and 10B) to insert and house the ceramic heating sheet 421 and the temperature sensor 423, and the opening 424 may cooperate with the frame 21 carrying the circuit board 41 to form a fragrance sheet slot 426 (refer to fig. 6B).

The fragrance module 42 includes a ceramic heating sheet 421, an infrared correlation element 422, and a temperature sensor 423. Wherein the ceramic heating plate 421 and the temperature sensor 423 are located in the opening 424, and power is taken from the circuit board 41 and a control signal is obtained via the leads. The infrared reflecting element 422 is disposed on the circuit board 41 on both sides of the opening 424 and is disposed adjacent to the upper edge of the circuit board 41. In fig. 9, because of the addition of the infrared correlation element 422, it is considered that the button 1242 of the fourth key 124 is shifted to the right appropriately to leave the arrangement space of the infrared correlation element 422.

In practical application, the aerogel heat-insulating sheet can be covered at the frame 21 matched with the opening 424, and the heat-resistant glue is smeared on the back of the ceramic heating sheet 421 and the back of the temperature sensor 423, so that the heat-resistant glue is firmly adhered to the aerogel heat-insulating sheet, and the temperature generated during the operation of the aromatherapy component 42 is prevented from being conducted to the circuit board 41 and the frame 21. Meanwhile, the connection mode of the leads can reduce the heat conduction of the high-temperature ceramic heating plate to the circuit board 41.

The infrared correlation element 422 is configured such that heating of the ceramic heating plate 421 is not activated when no insertion of the barrier (fragrance sheet holder and fragrance sheet held) into the opening 424 is detected.

After the infrared correlation element 422 detects the existence of the aromatherapy sheet support and the aromatherapy sheet supported by the aromatherapy sheet support and the circuit board 41 heats the ceramic heating sheet 421, the temperature sensor 423 is further configured to: when the temperature is detected to be higher than a set threshold (for example, 70 degrees), the power supply heating to the ceramic heating plate 421 is stopped, and the fragrance component is prevented from being volatilized too quickly or the safety risk is prevented from being brought about by too high temperature. The infrared correlation device 422 may be an IR-940 series infrared correlation device manufactured by using a photo technology of Xin Yongcheng, for example, or customized according to the size requirement.

Fig. 10A and 10B illustrate an aromatherapy sheet holder according to an embodiment of the present utility model. Wherein fig. 10A shows a perspective view of the fragrance sheet holder 420, and fig. 10B shows a left side schematic view of the fragrance sheet holder 420. As seen in connection with fig. 10A and 10B, the aromatherapy sheet holder 420 comprises a holder groove 4201, a top sheet 4202, protrusions 4203, and a baffle 4204. In particular, considering that the aromatherapy sheet is generally a soft material, the conventional slots have insufficient fixation to the aromatherapy sheet, so the bracket 4201 may be designed in a U-clip shape to prevent the aromatherapy sheet from moving vertically, and two baffles 4204 are respectively located at both sides of the bracket 4201 to block the aromatherapy sheet from moving laterally.

Further, when using the essential oil supplement aromatherapy sheet, considering that there may be an overflow of essential oil in the aromatherapy sheet soaked with the essential oil, an oil spill protection tampon may be placed at the inner sides of the two baffles 4204 and the bracket 4201.

Referring to fig. 9 and 10B, the protrusion 4203 functions to provide a lateral clamping force against the ceramic heating sheet 421 within the opening 424 after the fragrance sheet holder 420 is inserted into the fragrance sheet slot 426. Since the projections 4203 are positioned proximate to the topsheet 4202, additional "in place" insertion feel cues may also be provided. Furthermore, the protrusions 4203 may ensure contact between the aromatherapy sheet holder 420 and the ceramic heating sheet to thereby achieve heat conduction.

The top sheet 4202 of the fragrance sheet holder 420 is designed to contact a tool or fingernail to scratch the top sheet 4202 and pull the fragrance sheet holder 420 upward to replace fragrance sheets or supplement fragrance essential oil to fragrance sheets.

As shown in fig. 11, a transverse cross-sectional view from the location of the fragrance module 42 of the wall switch control panel.
