Detailed Description
In order to make the objects, features and advantages of the present utility model more comprehensible, the technical solutions according to the embodiments of the present utility model will be clearly described in the following with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments. 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.
The embodiment of the utility model provides a touch panel structure, which comprises a circuit board, a frame assembly and a bracket; the frame component is arranged on the back side of the circuit board and used for supporting the circuit board, and the support is positioned at the front end of the frame component and used for installing the touch panel structure and providing certain strength.
The components of the touch panel structure and the connection relationship between the components provided in the embodiment of the utility model are described below with reference to the accompanying drawings.
As shown in fig. 1 to 7, the frame assembly 2 includes a front end frame 21 and a rear end frame 22, the front end frame 21 and the rear end frame 22 are respectively bonded to the circuit board 1, for example, by double-sided adhesive, and the front end frame 21 covers a pressing area of the circuit board 1, and the rear end frame 22 covers an area other than the pressing area of the circuit board 1; the front end frame 21 is a metal front end frame, the rear end frame 22 is a plastic rear end frame, and the thickness of the front end frame 21 is smaller than the thickness of the rear end frame 22.
The Z-direction space of the rear end frame 22 is partially free, so that the space (thickness) requirement of the part is relatively low, and therefore, the plastic rear end frame can be used at the position, and the plastic rear end frame is lower in cost and better in stability compared with the metal frame; the front end frame 21 is located at a position where the Z-direction space is limited, and thus, a relatively thinner metal front end frame can be employed. The metal front end frame is combined with the plastic rear end frame and the frame assembly 2 has the advantages of a metal frame and a plastic frame.
For example, the metal front end frame is a stainless steel front end frame, and the plastic rear end frame is a plastic rear end frame; for example, the plastic is polycarbonate+30% glass fiber. The thickness of the metal front end frame is 0.3 mm to 0.7 mm, and the thickness of the plastic rear end frame is 1.3 mm to 1.7 mm. For example, the metal front end frame has a thickness of 0.5mm and the plastic rear end frame has a thickness of 1.5 mm.
In the embodiment of the utility model, the bracket 3 is overlapped with the front end frame 21 and is connected with the connecting structure of the touch panel structure; the bracket 3 is overlapped with the front end frame 21 for providing a certain supporting strength to the front end frame 21. When an elastic member is provided between the bracket 3 and the front end frame 21, the bracket 3 is used as a support, particularly as described later.
With continued reference to fig. 1 to 5, in the embodiment of the present utility model, a pressing spring arm 221 is provided at an end of the rear end frame 22 facing the front end frame 21, and the pressing spring arm 221 is provided in a middle portion of an end of the rear end frame 22 facing the front end frame 21; the pressing spring arm 221 has a pressing structure 222 at an end thereof, and the front end frame 21 has a through hole 211, and the pressing structure 222, the through hole 211, and the switch on the circuit board 1 are stacked.
When the circuit board 1 is pressed, the switch on the circuit board 1 is connected with the pressing structure 222, so that the pressing operation is completed. After the pressing operation is completed, the pressing spring arm 221 is reset, and the next pressing operation can be performed.
As shown in fig. 5, for example, a side of the pressing structure 222 facing the switch 11 or the switch 11 is provided with an interference protrusion 227; the pressing structure 222 pre-presses the switch through the interference protrusion 227. On the pressing structure 222, a side away from the interference protrusion 227 has a gap, such as a gap interval of 0.05 mm, from the holder 3. By providing the interference protrusion 227, the switch can be initially elastically preloaded, and thus the trigger force of the touch panel can be properly reduced. In addition, the interference protrusion 227 can cancel the stamping boss structure on the support 3, and from the perspective of tolerance analysis, replace the relatively unstable stamping size (impact of stamping deformation, impact of drawing material on thickness, etc.) with the relatively stable plastic thickness size (mold forming), which is more beneficial to the hand feeling stability of the touch panel structure pressing.
As shown in fig. 6, in the embodiment of the present utility model, one end of the rear end frame 22 facing the front end frame 21 is further provided with a reset spring arm 223, and two sides of the pressing spring arm 221 are respectively provided with a reset spring arm 223; the end of the return spring arm 223 is located between the front end frame 21 and the bracket 3, and abuts against the bracket 3.
The reset spring arms 223 provide spring force on two sides of the touch panel structure, which can provide enough reset strength, so as to avoid the deformation of the touch panel structure.
For example, the pressing spring arm 221 and the return spring arm 223 are integrally structured with the rear end frame 22. The integrally formed structure may increase the strength of the rear end frame 22, as well as the cost of manufacturing.
As shown in fig. 4, in the embodiment of the present utility model, a stand plate 224 is disposed at one end of the rear end frame 22 away from the pressing spring arm 221 and the resetting spring arm 223, and a locking lug 225 is disposed on the stand plate 224; the rear end frame 22 is removably coupled to the touchpad structure via a latch 225. The rear end frame 22 is provided with a support step 226 for supporting the battery on a side remote from the circuit board 1. The supporting step 226 is used for supporting the edge of the battery, and a certain gap is formed between the supporting step 226 and the battery, so that the battery can be protected from impact when being stressed.
As shown in fig. 3 and 7, in the embodiment of the present utility model, the front end frame 21 is provided with first reinforcing ribs 212 on both sides of the through hole 211, and the bracket 3 is provided with second reinforcing ribs 31. The front end frame 21 and the bracket 3 are provided with a reinforcing rib structure, so that the spring arm stroke of the pressing spring arm 221 and the resetting spring arm 223 can be ensured by the strength of the spring arm.
For example, the front end frame 21 and the bracket 3 are respectively provided with spring arm regions disposed opposite to the reset spring arm 223; the first reinforcing rib 212 and the second reinforcing rib 31 are located in a region other than the spring arm region.
With continued reference to fig. 7, in the embodiment of the present utility model, the edge of the bracket 3 is provided with a reinforcing flange 32, and a gap of 0.1mm is reserved between the height of the reinforcing flange 32 and the male die surface of the shell, where the positions of the reinforcing flanges 32 at two trip positions of the bracket 3 are connected together to increase the strength thereof.
The embodiment of the utility model also provides an electronic product, which comprises the touch panel structure.
In the touch panel, a spare part is stacked in a Z-direction space at the rear end, a plastic rear end frame is adopted as a frame, and a metal front end frame is adopted as a part with insufficient front end space; compared with an all-metal frame, the riveting and laser processes are omitted, the stainless steel area is reduced, the material cost is effectively saved, and meanwhile, the size of the frame is more stable, and deformation caused by stress is avoided. According to the technical scheme, the frame of the touch panel adopts a mode of combining the metal front end frame and the plastic rear end frame, and has the advantages of the metal frame and the plastic frame, so that the touch panel is particularly suitable for an ultrathin application scene.
