[0028] The following is a further detailed description of the specific implementation of the present utility model in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the related art, the expansion dock cannot be well fixed when facing different external devices. The inventor found that since the sizes of external devices are not uniform, when external devices of different thicknesses are placed on the expansion dock, the fixed-size clamping parts on the expansion dock cause the external devices to easily loosen, affecting the user experience.

[0031] In view of this, if Figures 1 to 5 As shown, some embodiments of the utility model provide an expansion device, including: a shell 1, a buffer pad 2 and a connecting line 3; a groove 4 is provided on the shell 1, the buffer pad 2 is provided on the side wall of the groove 4 and is detachably connected to the groove 4, and two sides of the electronic device are respectively abutted against the side wall of the groove 4 and the buffer pad 2; two ends of the connecting line 3 are respectively connected to the electronic device and the shell 1.

[0032] In the above embodiment, the buffer pad 2 can be made of rubber or silicone. There can be multiple buffer pads 2, which are all arranged on the same plane. The multiple buffer pads 2 can be arranged at intervals along the length direction of the groove 4. There can be two buffer pads 2, which are respectively arranged at both ends of the groove 4, so that the electronic device inserted into the groove 4 can be abutted by the two buffer pads 2, making the electronic device more secure. Further, the buffer pad 2 can be provided with different thicknesses, and the thickness of the buffer pad 2 can be 0.5 cm to 5 cm. For example, the thickness of the buffer pad 2 can be selected from 0.5 cm, 1 cm, 2 cm, 4 cm, etc. There are two buffer pads 2 of each different thickness, so that when electronic devices of different thicknesses are inserted into the groove 4, the electronic devices of different thicknesses can be fixed by assembling buffer pads 2 of different thicknesses.

[0033] Optionally, the shell 1 can be made of metal or plastic. The shell 1 can be laid flat on the office desktop. A groove 4 is provided at the end of the shell 1 away from the office desktop. The groove 4 includes a bottom and two side walls. A plurality of buffer pads 2 can be provided on the side wall of the groove 4 close to the user or on the side wall away from the user. When the electronic device is inserted into the groove 4, the two sides of the electronic device can abut against the side walls of the groove 4 and the buffer pads 2, and the end face of the electronic device inserted into the groove 4 can abut against the bottom of the groove 4 to fix the electronic device.

[0034] Optionally, the connecting cable 3 includes a data cable. The connecting cable 3 can adopt a TYPE-C interface or a MicroUSB interface. One end of the connecting cable 3 is arranged on the end surface of the shell 1 facing away from the user, and the other end is connected to the electronic device to realize the electrical connection between the electronic device and the shell 1. At the same time, a data cable connected to other electronic devices can be arranged on the end surface of the shell 1 facing away from the user.

[0035] In an expansion device provided by some embodiments of the utility model, a buffer pad 2 is fixed on the side wall of a groove 4 of a shell 1. When an electronic device is inserted into the groove 4, the detachable buffer pad 2 can be replaced according to the thickness of the electronic device, so that the electronic device can be firmly connected in the groove 4 through the side wall of the groove 4, the bottom of the groove 4 and the buffer pad 2, and the expansion of the electronic device can be achieved through the connecting line 3, so that the user experience is better.

[0036] In some optional embodiments, the groove 4 penetrates the shell 1 along the length direction of the shell 1.

[0037] In the above embodiment, the two side walls and the bottom of the groove 4 can be set to be planes, and the two side walls of the groove 4 are arranged parallel to each other so that the width of the groove 4 at different positions is consistent, so that the electronic device can be fixed in cooperation with the buffer pad 2. Furthermore, the groove 4 is set to pass through the shell 1 so that when the length of the electronic device is greater than the length of the shell 1, after the electronic device is inserted into the groove 4, the two ends of the electronic device can extend from the two ends of the groove 4 to avoid the electronic device being too long to be inserted into the groove 4, thereby having size requirements for the connected electronic device.

[0038] In some optional embodiments, the recessed direction of the groove 4 is perpendicular to the user's line of sight, and a buffer pad 2 is provided on the side wall of the groove 4 away from the user.

[0039] In the above embodiment, the concave direction of the groove 4 is a direction parallel to the two side walls of the groove 4, and the two side walls of the groove 4 are arranged at an angle to the height direction of the shell 1, wherein in the direction in which the height of the shell 1 increases, the distance between the side walls of the groove 4 and the user is arranged to increase, so that after the electronic device is placed in the groove 4, the distance between the electronic device and the user is arranged to increase along the direction in which the height of the shell 1 increases, so that when the user lowers his head on the desk, his line of sight is arranged vertically to the display screen of the electronic device, thereby meeting the user's usage needs.

[0040] Optionally, a buffer pad 2 is provided on the side wall away from the user of the two side walls of the groove 4. Because the recessed direction of the groove 4 is arranged perpendicular to the user's line of sight, the distance between the electronic device and the user is arranged increasing in the direction of increasing height of the shell 1. Therefore, after the electronic device is inserted into the groove 4, the electronic device exerts a greater pressure on the side wall away from the user. In order to prevent the electronic device from being damaged and to better fix the device, a buffer pad 2 is provided on the side wall away from the user, which can reduce damage to the surface of the electronic device and increase the service life of the electronic device.

[0041] In some optional embodiments, a card slot 5 is provided on the buffer pad 2 , a card claw 6 is provided in the groove 4 , and the card claw 6 extends into the card slot 5 and is slidably connected with the card slot 5 .

Further, a clamping claw 6 is provided on the side wall of the groove 4 away from the user, and the clamping claw 6 can be provided in four. The clamping claw 6 can be integrally formed with the shell 1, or can be bonded to the shell 1, and the four clamping claws 6 are respectively arranged in pairs in the groove 4. At the left and right ends, in each group of clamping claws 6, two clamping claws 6 are symmetrically arranged, and the cross-section of each clamping claw 6 is a right angle. One right-angled side of the two clamping claws 6 are parallel to each other, and the other right-angled sides are arranged close to each other, so that when the buffer pad 2 extends into the groove 4, the grooves 5 on the left and right sides of the buffer pad 2 are aligned with the clamping claws 6, so that the clamping claws 6 on both sides are clamped into the grooves 5, and the buffer pad 2 moves toward the bottom of the groove 4 until the end face of the buffer pad 2 abuts against the bottom of the groove 4, thereby achieving the fixation of the buffer pad 2 and the groove 4.

[0043] In some optional embodiments, the height of the engaging claw 6 is smaller than the height of the side wall of the groove 4 away from the user.

[0044] In the above embodiment, the extension direction of the clamping claw 6 is consistent with the width direction of the side wall of the groove 4, and the clamping claw 6 is arranged at the bottom of the groove 4 and abuts against the bottom, and a gap is arranged between the other end of the clamping claw 6 and the edge of the side wall of the groove 4, and the length of the buffer pad 2 can be set to be consistent with the width of the side wall of the groove 4. When the buffer pad 2 is connected to the clamping claw 6, after the buffer pad 2 is extended into the clamping claw 6, the side of the buffer pad 2 away from the bottom of the groove 4 is not provided with the groove 4, so the side of the buffer pad 2 away from the bottom of the groove 4 is stronger. In the process of replacing the buffer pad 2, the user's fingers can hold the buffer pad 2 through the side of the groove 4 away from the bottom of the groove 4, and plug and unplug the buffer pad 2, which is more convenient for replacement.

[0045] Optionally, a hollow portion is provided on the side wall close to the user of the two side walls of the groove 4, and the hollow portion is provided in the middle position of the side wall. The height of the hollow portion is lower than the side walls of the groove 4 on the left and right sides, so that after the electronic device is inserted, the middle position can have a better field of view to avoid blocking the screen of the electronic device.

[0046] In some optional embodiments, the opening of the card slot 5 is provided with rounded corners.

[0047] In the above embodiment, the opening ends of the slots 5 on the left and right sides of each buffer pad 2 are provided with rounded corners. The rounded corners can be respectively provided on both sides of the slot 5, and the diameters of the rounded corners on both sides can be consistent, so that the rounded corners can play a guiding role at the opening of the slot 5, which is more convenient when the slot 5 is connected with the clamping claw 6.
