Because the lamp panel 2 is provided with the matching piece 21, the matching piece 21 can be magnetically attracted to the adsorbing piece 11, that is, the lamp panel 2 can be magnetically attracted to the adsorbing piece 11. Further, the adsorbing member 11 is part of the structure of the adjustable fixing device, and the adjustable fixing device 1 is fixedly disposed in the through hole on the bottom plate 31 of the back plate 3, so that the connection mode between the lamp panel 2 and the back plate 3 is actually a magnetic connection. Because the lamp panel is installed in a magnetic adsorption mode, the lamp panel is more firm after being installed on the back plate, and is not easy to fall off.

Through pasting fitting piece 21 at the lamp plate 2 back, be convenient for on the one hand with backplate 3 carry out magnetism and inhale the connection, on the other hand based on the high strength characteristic of the material of fitting piece 21, can improve the warpage of lamp plate 2, improve the life of lamp plate 2.
In some embodiments, as shown in fig. 1-4, the adjustable fixation device 1 further comprises: and a magnetic member 13 fixedly connected with the control member 12, the magnetic member 13 having two magnetic poles of opposite magnetism, the magnetic member 13 being configured to rotate under the control of the control member 12, the two magnetic poles being disposed opposite to each other in a rotation radial direction thereof. The magnetic member 13 may be a permanent magnet device.
The control member 12 is fixedly connected to the magnetic member 13, specifically, may be connected by welding or bonding, which is not limited in the embodiment of the present disclosure. In another example, the control member 12 may be integrally connected with the magnetic member 13, that is, the control member 12 and the magnetic member 13 are made of the same material, in which case, in order to avoid affecting the switching of the suction state of the suction member 11, the control member 12 is not in contact with the suction member 11.
In some embodiments, as shown in fig. 1-4, the absorbent member 11 comprises: the magnetic member 13 is positioned between the two magnetic conductive portions 111, and when the magnetic member 13 rotates to the two magnetic poles respectively close to the two magnetic conductive portions 111, the two magnetic conductive portions 111 have magnetism.
Specifically, the magnetic member 13 rotates under the control of the control member 12, and the two magnetic poles on the magnetic member 13 can form closed magnetic lines with the two magnetic conductive portions 111 and the matching member 21 of the lamp panel 2 during the rotation process, so that the magnetic conductive portions 111 have magnetism to attract the lamp panel 2.
In some embodiments, the absorbent member 11 further comprises: the two isolation parts 112 are oppositely arranged along the second direction Y, the isolation parts 112 are connected between the two magnetic conduction parts 111, the magnetic piece 13 is positioned between the two isolation parts 112, and when the magnetic piece 13 rotates to the state that the two magnetic pieces are respectively close to the two isolation parts 112, the two magnetic conduction parts 111 lose magnetism.
Specifically, when the lamp panel 2 needs to be disassembled, only the magnetic piece 13 needs to be rotated, and the two magnetic poles are close to the isolation part 112, so that the closed magnetic force lines are disconnected, and the adsorption force between the magnetizer and the lamp panel 2 disappears, so that the lamp panel 2 can be conveniently and conveniently disassembled, and the disassembly is simple and labor-saving.
In some embodiments, as shown in fig. 1-4, the surface of the magnetic conduction part 111 facing to one side of the accommodating space is flush with the first surface 3a, so that when the lamp panel 2 is placed in the accommodating space, on one hand, the lamp panel 2 is attached to the magnetic conduction part 111, and when the lamp panel 2 is in an adsorption state, the maximum adsorption force is provided for the lamp panel 2; on the other hand, the presence of protrusions is avoided, which affects the stability of the lamp panel 2 placed in the accommodation space.
In some embodiments, as shown in fig. 1-4, a gap is provided between the surface of the magnetic member 13 facing the accommodating space and the plane of the first surface 3 a. Further, when the lamp panel 2 is placed in the accommodation space, a gap is also provided between the magnetic member 13 and the lamp panel 2. Because the magnetic member 13 is always magnetic, it cannot switch states, if the magnetic member 13 is in direct contact with the light panel 2 or is applied to the light panel 2, the magnetic member will continuously provide an adsorption force to the light panel 2, and flexible disassembly and assembly between the light panel 2 and the back panel 3 cannot be realized.
In addition, since the magnetic member 13 needs to perform a rotational movement under the control of the control member 12 to change the magnetic pole direction, a gap exists between the magnetic member 13 and the first surface 3a, so that the problem that friction is generated due to contact with the lamp panel 2 during rotation, and adjustment flexibility is affected can be avoided.
As shown in fig. 3, a rotating space is provided between the two magnetic conductive parts 111, the magnetic member 13 is located in the rotating space, and the orthographic projection of the rotating space on the bottom plate 31 is circular, so that the magnetic member 13 is controlled to rotate by the control member 12, and the directions of the two magnetic poles are adjusted.
As shown in fig. 1 to 4, a backlight module provided by an embodiment of the present disclosure includes a back plate 3, a lamp panel 2, and an adjustable fixing device 1 for detachably connecting the back plate and the lamp panel. Specifically, the adjustable fixing device 1 includes a control member 12, a magnetic member 13, and an adsorbing member 11, where the adsorbing member 11 includes a magnetic conductive portion 111 and an isolating portion 112, the magnetic member 13 is a rotatable portion, and two magnetic poles with opposite magnetism are disposed in a rotation radial direction of the magnetic member, and the direction of the two magnetic poles is changed by controlling the magnetic member 13 by the control member 12, so that the adsorbing member 11 can be switched between an adsorbing state and a non-adsorbing state to adsorb the lamp panel 2 or separate the lamp panel 2 from the back plate 3.
In one example, the control member 12 rotates the magnetic member 13 to position the extending direction of the connecting line of the two magnetic poles in the first direction X, that is, the two magnetic poles face the two magnetic conductive portions 111 oppositely arranged in the first direction X, at this time, the adsorbing member 11 is in an adsorbing state, and a closed magnetic force line is formed between the two magnetic conductive portions 111 and the lamp panel 2, so that the lamp panel 2 can be adsorbed, and the lamp panel 2 and the back panel 3 are firmly connected. In another example, the control member 12 rotates the magnetic member 13 to position the extending direction of the two magnetic pole connecting lines in the second direction Y, that is, the two magnetic poles face the two separating portions 112 disposed opposite to each other in the second direction Y, but it should be noted that, at this time, each magnetic pole faces the separating portion 112 and contacts the two magnetic conducting portions 111, that is, for one magnetic conducting portion 111, it contacts both the two magnetic poles in the second direction Y, at this time, the adsorbing member 11 is in the non-adsorbing state, and the magnetic force lines between the magnetic conducting portions 111 and the lamp panel 2 are cut off, so that the lamp panel 2 is separated from the back plate 3.
It should be understood that in this embodiment, the magnetism on the attraction member 11 is provided by the magnetic member 13, specifically by rotating the magnetic member 13 to face, and changing the magnetic pole direction changes the attraction state of the attraction member 11. In an example, the magnetic member 13 may be an electromagnet structure, that is, when the voltage is applied, there is magnetism on the magnetic member 13, when the voltage is removed, there is no magnetism on the magnetic member 13, at this time, the rotating member does not need to be rotationally controlled, the magnetic direction of the rotating member always faces the two magnetic conductive portions 111, and the magnetic state of the magnetic member 13 can be controlled by the voltage, so as to further control the adsorption state of the adsorption member 11.
In some embodiments, the magnetically permeable portion 111 is a magnetically permeable material comprising pure iron.
In some embodiments, the spacer 112 is a non-magnetically permeable material, including brass.
