Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic device accessories, in particular to a mobile phone support with self-locking knob. BACKGROUND

[0002] The common vehicle-mounted mobile phone fixing support on the market is usually clamped and fixed by the elastic clamping arms on the left and right sides during use, and the mobile phone is tightly clamped by the elastic clamping arms on the left and right sides under the action of the elastic structure. The device that exerts clamping force on the two sides of the mobile phone through the elastic structure will exert excessive pressure on the two sides of the mobile phone shell after long-term use, thereby causing damage to the mobile phone shell.

[0003] Therefore, a mobile phone support that can actively adjust the opening range of the clamping arms appears on the market, which avoids damage caused by excessive clamping of the mobile phone by actively adjusting the opening range of the clamping arms. However, the mobile phone support that can actively adjust the opening range of the clamping arms does not have a self-locking function, and when the clamping arms are subjected to an outward force, the clamping arms will be opened, thereby resulting in poor clamping effect.

When the knob is the power input end, the knob drives the elastic piece to rotate relative to the locking piece, and the first clamping arm makes opening and closing movement. When the transmission rod is the power input end, the elastic piece and the locking piece are in abutment and locked.

[0006] In some embodiments, the locking piece is sleeved on the connection between the transmission rod and the knob, the inner ring of the locking piece is formed with a latch in the circumferential direction, the elastic piece is fixedly installed on the transmission rod and abuts against the latch, and the knob is provided with a first abutment portion. When the knob rotates, the first abutment portion can exert a pressure on the elastic piece to separate the elastic piece from the latch.

[0007] In some embodiments, the knob is provided with a mounting groove in the axial direction, which is in transmission connection with the transmission rod, the transmission rod is provided with a mounting end matched with the mounting groove, the elastic member is at least partially contained in the mounting groove, and the locking member is sleeved outside the mounting groove.

[0008] In some embodiments, the mounting end is formed with a positioning part protruding towards the direction of the knob and a mounting part for mounting the elastic member, and the mounting groove is provided with a positioning groove matched with the positioning part.

[0009] In some embodiments, the elastic member comprises an elastic member body and extension parts located at both ends of the elastic member body and extending towards the direction of the mounting part and approaching each other, and the extension part ends are in abutting connection with the clamping teeth.

[0010] In some embodiments, the first abutting part is obliquely arranged on both sides of the extension part, and the first abutting part pushes the extension part on one side to move towards the direction of the mounting part when the knob rotates.

[0011] In some embodiments, the mounting part is arranged in a spaced manner with the positioning part, and the elastic member is fixed in the space between the mounting part and the positioning part.

[0012] In some embodiments, the mounting part is in an arc structure, and the extension part end is formed with a second abutting part matched with the clamping teeth for abutting connection and a third abutting part abutting with the mounting part for limiting.

[0013] In some embodiments, the back plate is provided with a second clamping arm which can be opened and closed on the side perpendicular to the movement direction of the first clamping arm, and the side part of the back plate is provided with a switch member which can be moved to control the opening and closing amplitude of the second clamping arm.

[0014] In some embodiments, the second clamping arm is provided with a rack extending into the back plate, the inside of the back plate is provided with a second transmission gear meshed with the rack, and the switch member is provided with a protruding locking part matched with the second transmission gear for locking, and moving the switch member can make the locking part engaged with or disengaged from the second transmission gear.

[0015] According to the above content, the beneficial effects of the technical scheme of the utility model compared with the prior art are that the clamping arms on the left and right sides of the mobile phone support can only control the opening and closing amplitude through the knob, when the clamping arms are subjected to other external forces, the locking member and the elastic member are matched with each other to lock the clamping arms, and the clamping arms cannot move.
