The elastic member 40 may be a spring, and the magnetic connecting block 31 has two magnetic faces, an N-pole face and an S-pole face.

In the case that the telescopic assembly 30 is in the contracted state, the two corresponding magnetic surfaces of the two rows of magnetic connecting blocks 31 formed in the accommodating chamber 12 have opposite magnetic poles, for example, the magnetic surface of the side of the upper row of magnetic connecting blocks 31 facing the housing 10 is an S-pole surface (see fig. 8), and the magnetic surface of the side of the lower row of magnetic connecting blocks 31 facing away from the housing 10 is an N-pole surface. When the telescopic assembly 30 is in the unfolded state, the magnetic poles of the row of magnetic connection blocks 31 formed in the accommodating chamber 12 facing the magnetic surface of the display screen 50 are the same, for example, the magnetic surface of the row of magnetic connection blocks 31 facing away from the housing 10 is an N-pole surface (see fig. 12).

According to an embodiment of the present invention, the elastic coefficients of the plurality of elastic members 40 sequentially increase or sequentially decrease in the first direction of the support member 20.

In other words, the elastic force of the plurality of elastic members 40 may sequentially increase or sequentially decrease in the moving direction of the supporting member 20. In the present application, the specific description is given by taking an example that the elastic coefficients of the plurality of elastic members 40 can be sequentially reduced in the moving direction of the supporting member 20 away from the accommodating chamber 12.

The number of folding support blocks 32 in the telescopic assembly 30 of the present application is not limited in number. During the expansion of the telescopic assembly 30, as shown in fig. 12, the magnitude of the elastic force (elastic modulus) of the spring of the elastic member 40 is as follows: 823060, F1F 2F 3F 4 8230to ensure that the folding support blocks 32 can move in sequence during the expansion or contraction process of the telescopic assembly 30. When the support member 20 moves rightwards, the folding supporting block 32 is pulled to move synchronously, the movement track of the lower row of magnetic connecting blocks 31 under the guiding action of the shell 10 is shown in fig. 12, and when the folding supporting block 32 moves to the upper side completely and is flattened, the self elastic force of the springs is counteracted.

During the contraction of the telescopic assembly 30, referring to fig. 8, the magnitude of the elastic force (elastic modulus) of the spring is as follows: 8230J F1> F2> F3> F4 > 8230J to ensure that the folding support blocks 32 can move in sequence during the expansion or contraction of the telescoping assembly 30. When the supporting member 20 moves leftward, the magnetic connecting blocks 31 in the upper and lower rows move downward under the magnetic attraction force and turn around the mating posts 322 of the folding supporting block 32 to contract under the spring contraction force.

The electronic equipment not only can be used for mobile terminals such as smart phones, but also can be applied to electronic products such as tablet computers and intelligent wearable products. Of course, other structures of the electronic device and the working principle thereof are understood and can be realized by those skilled in the art, and detailed description is omitted in the present application.

In summary, according to the display panel supporting mechanism 100 of the embodiment of the present invention, the supporting member 20 and the telescopic assembly 30 jointly support the display panel 50, and when the telescopic assembly 30 is switched between the retracted state and the extended state, the supporting member 20 can be driven to move between the first position and the second position, so as to retract and extend the display panel supporting mechanism 100. And under the condition that flexible subassembly 30 is located the shrink state, the magnetism connecting block 31 on folding supporting shoe 32 can form two rows at least, makes support piece 20 be located the second position, and folding supporting shoe 32 and magnetism connecting block 31 are used for supporting the surface and the holding surface parallel and level of display screen 50 jointly, makes flexible subassembly 30 and support piece 20 be located the same horizontal plane under the shrink state, guarantees to carry out level and smooth support to display screen 50. Under the condition that the telescopic assembly 30 is located the expansion state, a plurality of magnetic connecting blocks 31 form one row, and support piece 20 is located the first position, and folding supporting shoe 32 and magnetic connecting block 31 be used for supporting display screen 50's surface and holding surface parallel and level jointly make telescopic assembly 30 and support piece 20 be located same horizontal plane under the expansion state, guarantee to level and smooth the support to display screen 50 to improve the screen failure risk, promote user's use experience.
