Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone accessories, and in particular to a shielding cover bracket for mobile phones. Background Technology

[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and the outward radiation of electromagnetic waves generated internally. It is commonly found in mobile phones and is generally placed on the outside of the mobile phone circuit board to shield electronic signals. It is a common mobile phone accessory.

[0003] Most existing shielding covers are directly clipped onto the outside of the phone's circuit board. When the phone's casing is subjected to external impacts that cause the shielding cover to deform, the shielding cover and the bracket may also deform, causing the bracket to come into direct contact with the electronic components on the circuit board. This could damage the electronic components and cause a short circuit in the phone. The shielding cover is not very stable and provides poor protection for the electronic components, leaving room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a shielding cover bracket for mobile phones, so as to solve the problem mentioned in the background art that existing mobile phone shielding covers and brackets may be deformed by external pressure and come into contact with electronic components on the mobile phone circuit board, resulting in damage to electronic components and affecting the normal use of the mobile phone.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shielding cover bracket for mobile phones, comprising a shielding cover body and a protective cover, wherein a bracket body is fixedly connected to the upper surface of the shielding cover body, two inspection grooves are provided on the upper surface of the shielding cover body, and a buffer groove is provided on the upper surface of the protective cover, the size of the buffer groove being the same as the size of the shielding cover body, and buffer components are fixedly connected to the four corners of the lower surface of the shielding cover body.

[0006] The buffer assembly is used to disperse and buffer the direct impact on the shield body, so as to avoid short circuits caused by contact between the support body and electronic components.

[0007] Preferably, the buffer assembly includes a circular sleeve with a circular groove at the bottom end. The inner wall of the circular groove has two limiting grooves. A first connecting circular plate is fixedly connected to the inner top wall of the circular groove. A spring is fixedly connected to the lower surface of the first connecting circular plate. A second connecting circular plate is fixedly connected to the bottom end of the spring. A buffer column is slidably connected to the inner wall of the circular groove. The top end of the buffer column is fixedly connected to the lower surface of the second connecting circular plate.

[0008] Preferably, the surface of the buffer column is fixedly connected to two limiting blocks, and the two limiting blocks are symmetrically arranged on both sides of the buffer column. The side of the two limiting blocks away from the buffer column is slidably connected to the inner wall of the two limiting grooves respectively.

[0009] Preferably, the bottom end of the buffer column is fixedly connected to a threaded column, the surface of the threaded column is threadedly connected to a threaded sleeve, the bottom end of the threaded sleeve is fixedly connected to a limit plate, and the lower surface of the limit plate is threadedly connected to four limit bolts.

[0010] Preferably, the lower surface of the protective cover has circular through holes at positions corresponding to the four buffer components, and the lower surface of the protective cover has four limiting threaded grooves at positions corresponding to the circular through holes.

[0011] Preferably, the inner diameter of the circular through hole is larger than the diameter of the buffer post and the threaded post, and the limiting threaded groove is adapted to the limiting bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This mobile phone shield bracket, through the setting of the buffer component, can use the protective cover to be clipped to the outside of the shield body during use, and use the limiting bolts and limiting discs to lock the buffer columns and the protective cover. When the protective cover is subjected to external pressure, the protective cover can directly drive the four buffer columns to compress the springs. The reaction force generated by the four springs can disperse the external pressure, ensuring that the internal shield body and bracket body will not deform and come into contact with electronic components, thereby improving the protection effect of electronic components and increasing stability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a shielding cover bracket for mobile phones, including a shielding cover body 1 and a protective cover 2. A bracket body 3 is fixedly connected to the upper surface of the shielding cover body 1. Two inspection grooves 4 are opened on the upper surface of the shielding cover body 1. A buffer groove 5 is opened on the upper surface of the protective cover 2. The size of the buffer groove 5 is the same as the size of the shielding cover body 1. Buffer components 6 are fixedly connected to the four corners of the lower surface of the shielding cover body 1.

[0021] The buffer assembly 6 is used to disperse and buffer the direct impact of the shield body 1, so as to avoid the short circuit caused by the contact between the bracket body 3 and the electronic components.

[0022] Furthermore, the buffer assembly 6 includes a circular sleeve 601. The bottom end of the circular sleeve 601 has a circular groove. The inner wall of the circular groove has two limiting grooves. The inner top wall of the circular groove is fixedly connected to a first connecting circular plate 602. The lower surface of the first connecting circular plate 602 is fixedly connected to a spring 603. The bottom end of the spring 603 is fixedly connected to a second connecting circular plate 604. The inner wall of the circular groove is slidably connected to a buffer post 605. The top end of the buffer post 605 is fixedly connected to the lower surface of the second connecting circular plate 604. When the buffer post 605 is impacted, it can compress the spring 603 through the second connecting circular plate 604, thereby causing the spring 603 to deform.

[0023] Furthermore, two limiting blocks 606 are fixedly connected to the surface of the buffer column 605, and the two limiting blocks 606 are symmetrically arranged on both sides of the buffer column 605. The side of the two limiting blocks 606 away from the buffer column 605 is slidably connected to the inner wall of the two limiting grooves respectively. During the process of the buffer column 605 sliding up and down in the inner wall of the circular groove, it can drive the limiting blocks 606 to move up and down in the inner wall of the limiting groove. Due to the blocking effect of the limiting blocks 606 in the limiting groove, the buffer column 605 will not detach from the inner wall of the circular sleeve 601.

[0024] Furthermore, a threaded post 607 is fixedly connected to the bottom end of the buffer post 605. A threaded sleeve 608 is threadedly connected to the surface of the threaded post 607. A limiting plate 609 is fixedly connected to the bottom end of the threaded sleeve 608. Four limiting bolts 610 are threadedly connected to the lower surface of the limiting plate 609. Circular through holes 611 are opened on the lower surface of the protective cover 2 at positions corresponding to the four buffer components 6. Four limiting threaded grooves 612 are opened on the lower surface of the protective cover 2 at positions corresponding to the circular through holes 611. The inner diameter of the circular through holes 611 is larger than the diameter of the buffer post 605 and the threaded post 607. The limiting threaded grooves 612 are adapted to the limiting bolts 610, allowing the threaded post 607 and the buffer post 605 to pass through the circular through holes 611. The shield body 1 is inserted into the buffer groove above the protective cover 2. After the threaded sleeve 608 is screwed into the surface of the threaded post 607, the four limiting bolts 610 correspond to the positions of the four limiting threaded grooves 612 respectively. After the limiting bolts 610 are screwed into the limiting threaded grooves 612, the position of the limiting plate 609 is fixed. When the external pressure compresses the protective cover 2, the protective cover 2 can compress the buffer post 605 through the four limiting plates 609, and the buffer post 605 can compress the four springs 603. The four springs 603 can disperse the external pressure, thereby ensuring that the shield body 1 is not affected and the bracket body 3 will not deform and come into contact with the electronic components, thus improving the protection effect of the electronic components and preventing short circuits.

[0025] Working principle: After the shielding cover body 1 is clipped onto the outside of the mobile phone circuit board, the circular through hole 611 on the protective cover 2 passes through the threaded post 607 and the buffer post 605. At this time, four threaded sleeves 608 are screwed into the surface of the threaded post 607. After tightening, the positions of the four limiting bolts 610 correspond to the positions of the four limiting threaded grooves 612. Then, the four limiting bolts 610 are screwed into the limiting threaded grooves 612. The limiting bolts 610 can lock the relative position between the protective cover 2 and the buffer post 605 through the limiting plate 609. When the mobile phone is impacted, External pressure is not directly transmitted to the shielding cover body 1, but is instead compressed by the protective cover 2 to the four buffer pillars 605. The buffer pillars 605 can compress the springs 603 through the second connecting circular plate 604, thereby causing the springs 603 to generate a reaction force. The force of the four springs 603 can disperse the external pressure, thus ensuring that the shielding cover body 1 will not deform directly. Therefore, the bracket body 3 will not come into contact with the electronic components on the circuit board, thus providing better protection for the electronic components, preventing short circuits, and increasing stability.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
