In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present utility model, the meaning of "multiple" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically limited.

[0027] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to solve the problems existing in the prior art, the embodiments of the present application provide a magnetic instrument structure and a vehicle-mounted display screen.

[0029] like Figure 1 As shown, a magnetic instrument structure can be installed on a touch screen A, and includes a first magnetic component 1, a second magnetic component 2 and a knob screen 3; the first magnetic component 1 can be installed on the back side of the touch screen A, and can be electrically connected to the power supply circuit of the touch screen A to generate magnetism when the touch screen A is powered on; the second magnetic component 2 is fixedly mounted on a side away from the display side of the knob screen 3, and can be fixed to the side of the touch screen A opposite to the first magnetic component 1 through magnetic attraction.

[0030] The utility model provides a magnetic instrument structure, based on that the first magnetic component 1 can be installed on the back side of the touch screen A, and the first magnetic component 1 and the second magnetic component 2 can be magnetically connected to fix the knob screen 3 on the touch screen A, so there is no need to open the touch screen A, thereby avoiding the problem of dust entering the touch screen A and affecting the picture, improving the user experience, and the first magnetic component 1 is magnetic only when the touch screen A is powered on, so it is convenient to disassemble the knob screen 3 when it is not in use.

[0031] In some preferred embodiments, Figure 2 As shown, the first magnetic component 1 includes a suction cup 11 and an electromagnet 12; the electromagnet 12 is fixed to the suction cup 11 and can be electrically connected to the power supply circuit of the touch screen A; the suction cup 11 can be fixed on the plane on the back side of the touch screen A; based on fixing the electromagnet 12 with the suction cup 11, it can be installed without modifying the existing touch screen A, and the installation is more convenient. Moreover, based on the fact that the first magnetic component 1 and the second magnetic component 2 can be magnetically connected when the vehicle is working, the stability of the installation of the first magnetic component 1 can be improved, and the shaking of the vehicle during movement can be avoided to prevent the connection of the suction cup 11 from loosening.

[0032] In some preferred embodiments, Figure 2 and 3 As shown, the suction cup 11 is provided with an opening 111; the electromagnet 12 is installed in the opening 111; the electromagnet 12 is sealed and connected to the edge of the opening 111, for example, by a sealant; when the electromagnet 12 is installed in the opening 111, there is no obstruction between it and the touch screen A, and the magnetic attraction performance of the second magnetic component 2 will not be affected. Moreover, there is a certain distance from the surface of the touch screen A, so that the suction cup 11 has a larger negative pressure space for adsorption, thereby ensuring the stability of adsorption and fixation.

[0033] In some preferred embodiments, the opening 111 is interference fit with the electromagnet 12 to achieve a sealed connection; based on the sealed connection achieved by interference fit (i.e., sealing with the electromagnet 12 through the elasticity of the suction cup 11), it is convenient to replace the electromagnet 12; preferably, an annular groove adapted to the electromagnet 12 is provided on the inner side wall of the opening 111, and the annular groove accommodates the edge of the electromagnet 12 to increase the contact area with the electromagnet 12, thereby improving the sealing.

[0034] In some preferred embodiments, Figure 4 As shown, the second magnetic component 2 includes a magnetic body 21; the magnetic body 21 is installed on a side away from the display side of the knob screen 3; optionally, the magnetic body 21 can be made of iron or magnet material.

[0035] In some preferred embodiments, Figure 4As shown, the second magnetic component 2 also includes a buffer 22; the buffer 22 is arranged on the magnetic body 21 to prevent the magnetic body 21 from directly contacting the touch screen; based on the setting of the buffer 22, when the magnetic body 21 is prevented from directly contacting the touch screen A, during the rotation of the knob screen 3, the magnetic body 21 produces unexpected movement and damages the surface of the touch screen A; optionally, the buffer 22 is an elastic material or a flexible material structure, which is clamped between the magnetic body 21 and the touch screen A; preferably, there are multiple buffers 22, which are evenly distributed on the magnetic body 21, that is, there are gaps between adjacent buffers 22 to reduce the influence on the magnetic attraction of the first magnetic component 1 and the second magnetic component 2.

[0036] Preferably, the buffer 22 is an elastic structure arranged on the magnetic body 21. Based on the selection of the buffer 22 as an elastic material, when the first magnetic component 1 and the second magnetic component 2 are magnetically attracted, they can be squeezed to increase the contact area with the touch screen A, increase the friction, and thus improve the stability of the second magnetic component 2.

[0037] Preferably, the buffer 22 is provided with an anti-slip structure on the side facing the touch screen; the anti-slip structure is further provided to further improve the friction with the touch screen A, thereby improving the stability of the second magnetic component 2. Specifically, the anti-slip structure can be an anti-slip texture, anti-slip protrusion or anti-slip layer, etc.

[0038] Preferably, the buffer member 22 is a suction cup; based on setting the buffer member 22 as a suction cup, the suction force of the suction cup can better improve the stability of the second magnetic component 2.

[0039] A vehicle display screen, such as Figure 5 As shown, it includes the above-mentioned magnetic instrument structure and touch screen A; the magnetic instrument structure is installed on the touch screen A, and the first magnetic component 1 is electrically connected to the power supply line of the touch screen through ITO wiring.

[0040] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, all of which are within the protection of the utility model.
