Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and in particular to a short-circuit-proof display device for whole-house smart appliances. Background Art

[0002] Smart home display devices include touchscreen display switches or controllers, which are used to remotely control various smart appliances installed indoors. Touchscreen display switches mainly include push-type touchscreens (resistive touchscreens) and capacitive touchscreens. The former is controlled by pressing. When the touchscreen is subjected to pressure, the two conductive layers come into contact, forming a contact point. The latter, capacitive touchscreen technology, operates by utilizing the human body's current induction. When a finger touches the metal layer, the human body's electric field forms a coupling capacitor between the user and the touchscreen surface. For high-frequency current, capacitors are direct conductors, so the finger draws a very small current from the contact point, thereby determining the location of the touch point.

[0003] Currently, to prevent touchscreen short circuits, you can take the following measures: ① Regularly clean and maintain the touchscreen to keep it clean, avoid water on the touchscreen surface, and prevent dust and debris from accumulating inside the display, which increases the risk of short circuits. ② Avoid overheating by ensuring there is enough space around the touchscreen for heat dissipation and avoid placing it in direct sunlight or near heat sources, as overheating may cause circuit damage or short circuits. ③ Regularly check the power cord to ensure it is not damaged or worn, and avoid using damaged wires or sockets. Damaged wires may cause short circuits. ④ Install a leakage protector and other measures.

[0004] However, existing smart home display touch screens still have certain shortcomings during actual use: the touch screen is in an exposed state during use, easily accumulates dust and has poor anti-collision performance; when using a flip-up transparent protective frame purchased on the market to shield and protect the display device, the protective frame is large in size and easily accumulates dust on its surface, affecting the appearance. In order to ensure the transparency of the protective frame, it needs to be wiped frequently; the rest of the touch screen except the display screen is generally installed in a reserved hole in the wall. After a long period of operation, the heat dissipation performance of the display device is poor due to the closed nature of the reserved hole.

[0005] In view of this, the utility model proposes a short-circuit-proof display device for whole-house smart appliances. Utility Model Content

[0006] The utility model provides an anti-short-circuit display device for whole-house smart appliances, which solves the problems in the related art that existing smart home display devices have poor heat dissipation performance and lack good anti-collision performance.

[0007] The technical solution of the utility model is as follows: a short-circuit-proof display device for whole-house smart appliances, comprising: a panel, a display arranged on one side of the panel, and a connector installed at the rear end of the display, wherein a mounting cavity for placing the display is provided in the center of the panel, and the display is connected to the rear end of the panel via buffer components on all sides;

[0008] A U-shaped baffle is fixedly connected to the outer wall of the panel outside the installation cavity. A protective assembly is provided above the U-shaped baffle, comprising a transparent belt and a limiting rod fixed to the bottom of the transparent belt. Two hooks that cooperate with the limiting rods are symmetrically fixed to the bottom end of the U-shaped baffle. The space enclosed by the limiting rods and the U-shaped baffle is used to shield and protect the display.

[0009] A cleaning component is provided on one side of the protection component for wiping the outer wall of the transparent belt.

[0013] Preferably, the buffer assembly includes a positioning plate fixedly connected to the outer wall of the display, a slideway is provided inside the positioning plate, two connecting shafts are fixed inside the slideway, and the two connecting shafts are in a parallel state with each other.

[0014] Preferably, the inner sliding sleeve of the slide is provided with two sliders, the connecting shaft passes through the inside of the slider and is slidably connected thereto, a spring is connected between the slider and the end of the slide, and the spring is sleeved on the outer wall of the connecting shaft.

[0015] Preferably, an elastic strip is connected between the two sliding blocks, the elastic strip is arc-shaped, and the outer wall of the middle portion of the elastic strip is fixedly connected to the rear end wall of the panel.

[0016] Preferably, a ventilation hole communicating with the installation cavity is formed through the side wall of the panel, and the ventilation hole is S-shaped or broken line-shaped.

[0017] The working principle and beneficial effects of the utility model are as follows:

[0018] 1. In the present invention, a mounting cavity for a display is provided at the center of the panel. The display is connected to the rear end of the panel via buffer components on all sides. When the display is pressed or subjected to external collision, pressure is applied to the display. The display drives the positioning plate away from the panel, causing the two sliders inside the slide to slide along the outer wall of the connecting shaft and approach each other, stretching the spring and causing the elastic strip to deform. This cushions and offsets the collision force, protecting the display from collision and forceful pressing.

[0019] 2. In the present invention, ventilation holes are provided through the side wall of the panel and communicate with the installation cavity.

A protective assembly is provided above the U-shaped baffle. The protective assembly includes a transparent belt and a limit rod fixed to the bottom of the transparent belt. Two hooks that cooperate with the limit rods are symmetrically fixed to the bottom of the U-shaped baffle. The space enclosed by the limit rods and the U-shaped baffle is used to shield and protect the display. A cleaning assembly is provided on one side of the protective assembly. When the transparent belt is unfolding or reeling, the L-shaped hanging plate is rotated by switching, so that the sponge strip mounted on the inner side of the support frame can fit with the outer wall of the transparent belt. The sponge strip can then automatically wipe the outer wall of the moving transparent belt, avoiding the problem of poor clarity of the transparent belt caused by dust accumulation and dirt from touching.

[0029] The following will be combined with 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 only 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.

[0030] See also Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6 A short-circuit-proof display device for smart home appliances includes a panel 1, a display 6 mounted on one side of the panel 1, and a connector 5 mounted at the rear end of the display 6. A mounting cavity 102 for the display 6 is defined in the center of the panel 1. The display 6 is connected to the rear end of the panel 1 via buffer components 4 on all sides. Ventilation holes 101, which connect to the mounting cavity 102, are defined through the sidewall of the panel 1. These holes are S-shaped or zigzag-shaped, effectively preventing dust from entering the mounting cavity 102 while ensuring good ventilation and heat dissipation for the display device within the mounting cavity 102.

[0031] The buffer assembly 4 includes a positioning plate 403 fixed to the outer wall of the display 6 , a slideway 404 is provided inside the positioning plate 403 , two connecting shafts 405 are fixed inside the slideway 404 , and the two connecting shafts 405 are parallel to each other.

[0032] Furthermore, two sliders 402 are slidingly sleeved on the inner side of the slide 404, and the connecting shaft 405 passes through the inside of the slider 402 and is slidingly connected thereto. A spring 406 is connected between the slider 402 and the end of the slide 404, and the spring 406 is sleeved on the outer wall of the connecting shaft 405.

[0033] Furthermore, an elastic strip 401 is connected between the two sliders 402 . The elastic strip 401 is arc-shaped, and the outer wall of the middle portion of the elastic strip 401 is fixedly connected to the rear end wall of the panel 1 .

[0034] Specifically, when the display 6 is pressed, or when the display 6 is subjected to external collision, when pressure acts on the display 6, the display 6 drives the positioning plate 403 away from the panel 1, so that the two sliders 402 inside the slide 404 slide along the outer wall of the connecting shaft 405 and approach each other, stretching the spring 406. At the same time, the elastic strip 401 is deformed, thereby buffering and offsetting the collision force, and protecting the display 6 from collision and forceful pressing.

[0035] See also Figure 1 、 Figure 2 as well as Figure 3 A U-shaped baffle 3 is fixed to the outer wall of the panel 1 located outside the installation cavity 102, and a protective component 7 is provided above the U-shaped baffle 3. The protective component 7 includes a transparent belt 706 and a limiting rod 707 fixed to the bottom of the transparent belt 706. Two hooks 8 that cooperate with the limiting rod 707 are symmetrically fixed to the bottom end of the U-shaped baffle 3. The space enclosed by the limiting rod 707 and the U-shaped baffle 3 is used to shield and protect the display 6.

[0036] Furthermore, the protective component 7 also includes a fixing frame 701 fixed to the outer wall of the panel 1, and sleeves 703 are fixed at both ends of the inner cavity of the fixing frame 701. An axis rod 702 is rotatably connected between the two sleeves 703, and a coil spring 704 is connected between the axis rod 702 and the sleeve 703.

[0037] Furthermore, the transparent belt 706 is wrapped around the outer wall of the shaft 702, and one end of the transparent belt 706 is fixed to the shaft 702. A pulling groove 705 connected to the inner cavity of the fixing frame 701 is opened at the bottom of the fixing frame 701 for the transparent belt 706 to shuttle.

[0038] Specifically, by pulling down the limit rod 707, the limit rod 707 drives the transparent belt 706 to loosen from the shaft 702. At this time, the gradually unrolled transparent belt 706 drives the shaft 702 to rotate between the two sleeves 703, tightening the coil spring 704 until the limit rod 707 is sleeved into the two hooks 8 at the bottom of the U-shaped baffle 3. The limit rod 707 is constrained and limited by the hooks 8. At this time, the space enclosed by the transparent belt 706 and the U-shaped baffle 3 can shield and protect the display 6. It should be noted that when the display 6 used to control the whole house smart home appliances adopts a resistive touch screen, the display 6 can be pressed directly through the transparent belt 706, and the transparent belt 706 protects the touch screen from dirt. When the display 6 used to control the whole house smart home appliances adopts a capacitive touch screen, the limit rod 707 can be pulled out from the hook 8. Under the action of the coil spring 704, the shaft 702 rotates to automatically reel in the transparent belt 706.

[0039] See also Figure 2 and Figure 4 A cleaning component 2 is provided on one side of the protective component 7 for wiping the outer wall of the transparent belt 706.

[0040] The cleaning component 2 includes a fixed plate 205 fixed to the outer wall of the fixed frame 701. The fixed plate 205 is connected to an L-shaped hanging plate 203 through a conversion path 204. One end of the L-shaped hanging plate 203 is fixed to a supporting frame 202. A sponge strip 201 is detachably mounted on the inner side of the supporting frame 202. The sponge strip 201 is in contact with the outer wall of the transparent belt 706.

[0041] When the transparent belt 706 is being unfolded or rolled up, the L-shaped hanging plate 203 is rotated by the conversion path 204, so that the sponge strip 201 on the inner side of the supporting frame 202 can fit with the outer wall of the transparent belt 706, so that the outer wall of the moving transparent belt 706 can be wiped by the sponge strip 201, avoiding the problem of poor clarity of the transparent belt 706 due to dust accumulation and dirt when touched by hand.

[0042] Working principle and usage process: By pulling down the limit rod 707, the limit rod 707 drives the transparent belt 706 to loosen from the shaft 702. At this time, the gradually unfolded transparent belt 706 drives the shaft 702 to rotate between the two sleeves 703, tightening the coil spring 704 until the limit rod 707 is sleeved on the two hooks 8 at the bottom of the U-shaped baffle 3, and the limit rod 707 is constrained and limited by the hooks 8. At this time, the space enclosed by the transparent belt 706 and the U-shaped baffle 3 can shield and protect the display 6. It should be noted that when the display 6 used to control the smart appliances in the whole house adopts a resistive touch screen, the display 6 can be pressed directly through the transparent tape 706 to protect the touch screen from dirt. When the display 6 used to control the smart appliances in the whole house adopts a capacitive touch screen, the limit rod 707 can be pulled out from the hook 8, and under the action of the winding spring 704, the shaft 702 rotates to automatically reel in the transparent tape 706.

[0043] During the unfolding or reeling process of the transparent belt 706, the L-shaped hanging plate 203 is rotated by the switching mechanism 204, so that the sponge strip 201 set inside the supporting frame 202 can fit the outer wall of the transparent belt 706, thereby being able to wipe the outer wall of the moving transparent belt 706 by the sponge strip 201, thereby avoiding the problem of poor clarity of the transparent belt 706 caused by dust accumulation and dirt when touched by hands. It should be noted that the friction force is relatively large during the rotation of the L-shaped hanging plate 203 by the switching mechanism 204. Therefore, the L-shaped hanging plate 203 can stop and rotate at will, and has good stability. After long-term use, the sponge strip 201 can be removed from the supporting frame 202, making it convenient to replace the sponge strip 201.

[0044] When the display 6 is pressed, or when the display 6 is subjected to external collision, when pressure acts on the display 6, the display 6 drives the positioning plate 403 away from the panel 1, so that the two sliders 402 inside the slide 404 slide along the outer wall of the connecting shaft 405 and approach each other, stretching the spring 406. At the same time, the elastic strip 401 is deformed, thereby buffering and offsetting the collision force, and protecting the display 6 from collision and forceful pressing.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
