Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic devices, and in particular to a pressure touch panel module and an electronic device. Background Art

[0002] The current existing pressure touchpad module mainly consists of a protective film, a PCBA board, and an iron bracket, which are arranged in sequence from top to bottom. The front of the PCBA board is the touch surface, and the back of the PCBA board has an electromagnetic coil. Several magnets are installed between the back of the PCBA board and the iron bracket. When energized, the electromagnetic coil generates corresponding electromagnetic polarity, which repels or attracts the polarity of the magnet, thereby producing a vibrating feel. However, because the magnets used in current pressure touchpad modules are bar magnets, the north and south poles of the bar magnets are on different sides, and both sides are strong magnetic surfaces. When the pressure touchpad module is assembled with a battery, the side of the pressure touchpad module that contacts the battery is easily attracted by metal objects such as screws that have fallen from various workstations due to the strong magnetism of the magnet. Therefore, if the battery is assembled directly without care, it will interfere with the battery, and after being squeezed, the battery will be punctured, resulting in battery damage and the risk of spontaneous combustion.

[0003] To prevent screws from falling onto the magnet area of ​​the force trackpad module, a protective cover and a yellow adhesive film are typically added to the magnet area after assembly to identify the screws by color contrast. AOI (automated optical inspection) equipment is also added before battery assembly to check for screw adhesion. However, this significantly increases production costs and reduces assembly efficiency.

[0022] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0023] According to one embodiment of the present disclosure, the present utility model provides a pressure touch panel module. Figure 1-2 As shown, a pressure touch panel module includes a circuit board 1, a magnet 2 and a bracket 3. The circuit board 1 has an electromagnetic coil, and the first surface of the magnet 2 in contact with the circuit board 1 has an N pole 21 and an S pole 22 arranged in the same plane; the pressure touch panel module also includes a magnetic isolation member 4, which is arranged between the magnet 2 and the bracket 3.

[0024] In one embodiment, the first surface of the circuit board 1 is configured as a touch surface, and an electromagnetic coil is formed on the second surface. A protective film is applied to the touch surface of the circuit board. Furthermore, the number of electromagnetic coils is twice the number of magnets 2. The magnets 2 are arranged side by side and along the length and width of the bracket 3, with the length and width of the magnets 2 being equal to the length and width of the electromagnetic coils.

[0025] For example, the magnetic isolation member 4 is made of any one of ferromagnetic metal, magnetic isolation film and wave absorbing material.

[0026] For example, the bracket 3 has a crossbeam 31, the magnetic isolation member 4 is fixed on the crossbeam 31, and the magnet 2 is mounted on the magnetic isolation member 4. Specifically, the mounting method between the magnetic isolation member 4 and the magnet 2 can be any of the following:

[0027] The first method is to wrap the magnetic shield 4 around the second surface of the magnet 2, with the second surface of the magnet facing the first surface. Preferably, a groove is formed on the magnetic shield 4, and the second surface of the magnet 2 is fixed in the groove.

[0028] The second type is that the first surface of the magnetic isolation member is adhered to the bracket, the second surface of the magnetic isolation member is adhered to the second surface of the magnet, and the second surface of the magnet is arranged opposite to the first surface of the magnet.

[0029] The pressure touch panel module of the present application arranges the N pole and S pole of the magnet in the same plane, and both the N pole and the S pole are in contact with the circuit board 1. By setting a magnetic isolation member 4, the magnetic lines of force are isolated in the direction of the circuit board, thereby avoiding the risk of screw adsorption and improving assembly efficiency.

[0030] Because the magnet's north and south poles are coplanar, after the magnet is assembled onto bracket 3 and the circuit board, the magnet's magnetic force is reduced to less than 10% of its original value, making it unable to attract screws. By further adding a magnetic shield, the magnetic lines of force are isolated toward the circuit board, further reducing the magnetic force. Ultimately, the side of the pressure touchpad module facing the battery has almost no magnetic attraction, making it impossible for the pressure touchpad module to attract screws. This ensures the safety of the subsequent assembly of the pressure touchpad module and improves assembly efficiency.

[0031] For example, magnet 2 is a single-sided magnet. A single-sided magnet is one that is magnetic on one side and weaker on the other. The method is to wrap one side of the double-sided magnet with specially treated galvanized iron sheets. This shields the magnetism on the wrapped side, refracting the magnetic force to the other side, thereby enhancing the magnetism on the other side.

[0032] The principle behind the pressure touchpad module of this application is to utilize a U-shaped magnet to alter the magnetic field lines at the contact surface with the battery, thereby changing the magnetism of the contact surface and reducing the magnetic attraction. Existing solutions employ four bar magnets, with their north and south poles positioned one above the other, resulting in strong magnetic surfaces on different sides. This application, however, utilizes only two magnets, with their north and south poles aligned, resulting in a strong magnetic surface on the side facing the circuit board and a weak magnetic surface on the side facing away from the circuit board. Furthermore, this application employs magnetic isolation material to isolate the magnetic field lines of the magnets from the circuit board. This effectively eliminates the risk of serious quality accidents caused by screws being attracted and causing damage to the battery. Furthermore, during screw tightening during assembly of the pressure touchpad module, no labeling is required, simplifying module assembly and improving efficiency. Automated Optical Inspection (AOI) is also eliminated for screw inspection of the pressure touchpad module, simplifying the overall maintenance process. Furthermore, since this module only requires two magnets, production costs are reduced.

[0033] The following is a detailed description of the assembly process of the pressure touch panel module of the present application: provide a pressure touch panel bracket (i.e., a bracket), and adhere the magnetic isolation material to the crossbeam of the bracket; take two single-sided magnets and adhere the single-sided magnets to the magnetic isolation material; then take the PCBA circuit board, place the touch surface of the circuit board facing up, and attach the electromagnetic coil surface facing down to the single-sided magnet.

[0034] According to one embodiment of the present disclosure, the present invention further provides an electronic device including the pressure touch panel module described in any of the above embodiments. The electronic device including the pressure touch panel module can also improve module assembly efficiency and reduce the risk of battery damage caused by module adsorption screws.

[0035] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this disclosure can be achieved.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
