[0057] A foam cotton block 22 is adhered to one side surface of the wire tube 2, a through hole is formed in the middle of the foam cotton block 22, and the through hole and the outer surface of the wire tube 2 form an elastic glue injection groove 21.

[0058] In the above structure, the foam cotton block 22 with elasticity is adhered to the outer surface of the wire tube 2, which has the advantage of convenient operation; in addition, the through hole is processed in the middle of the foam cotton block 22, which also has the advantage of convenient processing; finally, the foam cotton block 22 and the outer surface of the wire tube 2 form the elastic glue injection groove 21, which not only ensures the glue amount, but also overcomes the problem of uneven wall thickness of the wire tube 2 after manual winding, and ensures the strength of the wire tube 2 after gluing.

[0059] Optionally, the adhesive glue includes a two-component structure epoxy glue. The two-component structure epoxy glue, also known as two-component epoxy resin glue, is an important thermosetting resin glue with excellent physical and mechanical properties, electrical insulation properties, chemical corrosion resistance, heat resistance and bonding properties.

In the processing technology, the two-component structure epoxy glue with high temperature rapid curing is used.

[0060] Optionally, the steps of forming the frame body 1 with the built-in cavity 11, forming the wire tube 2 for collecting the connection wires, and setting the elastic glue injection groove 21 on one side outer surface of the wire tube 2 and injecting the adhesive glue into the elastic glue injection groove 21 further include the following steps:

[0061] The frame body 1 has an arc structure, and the side of the wire tube 2 provided with the glue injection groove has an arc structure corresponding to the frame body 1.

[0062] The frame body 1 has an arc structure, and the side of the wire tube 2 provided with the glue injection groove also has an arc structure. The fixing structure can be used to fix the built-in part, the built-in part can include a battery, and the battery fixing bracket can be cancelled to simplify the fixing structure and improve the utilization rate of the built-in cavity 11.

[0063] Optionally, the steps of placing the wire tube 2 into the inside of the built-in cavity 11 and making the side of the wire tube 2 provided with the elastic glue injection groove 21 adhere to the inside wall of one side of the built-in cavity 11 further include the following steps:

[0064] The built-in cavity 11 penetrates through both ends of the frame body 1, one end of the built-in cavity 11 is provided with the first limiting part 4, and one end of the wire tube 2 abuts against the first limiting part 4.

[0065] The first limiting part 4 is detachably connected with the frame body 1, and can be fixed by screw connection or clamping, for example, a first clamping hole is arranged on the frame body 1, a first clamping buckle is arranged on the first limiting part 4, and the first limiting part 4 is fixed by clamping the first clamping buckle and the first clamping hole after being placed in the built-in cavity 11. When the wire tube 2 is placed in the built-in cavity 11, the first limiting part 4 has the function of positioning the wire tube 2, so that the wire tube 2 is glued at a preset position of the built-in cavity 11, and the wire tube 2 is prevented from being glued at an incorrect position, thereby affecting the placement of the built-in cavity 11.

[0066] Optionally, the step of placing the pressing jig 3 in the interior of the built-in cavity 11, pressing the wire tube 2 against the inner wall of the built-in cavity 11, and deforming the elastic glue injection groove 21 further includes the following steps:

[0068] Similarly, the second limiting part 5 is detachably connected with the frame body 1, and can be fixed by screw connection or clamping, for example, a second clamping hole is arranged on the frame body 1, a second clamping buckle is arranged on the first limiting part 4, and the first limiting part 4 is fixed by clamping the second clamping buckle and the second clamping hole after being placed in the built-in cavity 11. The second limiting part 5 has the function of limiting the position of the pressing jig 3, and can quickly install the pressing jig 3 at a preset position, so that the pressing jig 3 can press the wire tube 2, until the wire tube 2 is glued in the built-in cavity 11. The second limiting part 5 also has the function of limiting the position of the built-in part, and can quickly install the built-in part at a preset position.

[0071] Although the two-component structural adhesive can be cured after being placed at room temperature for 24 hours, the curing time is too long, so that the curing time of the two-component structural adhesive can be greatly shortened by using an oven for heating, thereby improving the processing efficiency.

[0072] Optionally, after the step of placing the assembly formed by the frame body 1, the wire tube 2 and the pressing jig 3 in an environment with a preset temperature, and taking out the pressing jig 3 after the adhesive is cured, the following step is further included:

[0076] The battery forms an arc-shaped structure matched with the built-in cavity 11 and the wire tube 2, so that the battery and the wire tube 2 abut against each other and fill the built-in cavity 11.

[0077] The overall shape of the pressing jig 3 is basically the same as the shape, structure and size of the battery, so that the pressing jig 3 becomes a special gluing jig for the hidden frame, ensures that the assembly of the battery and the gluing of the wire tube 2 meet the design requirements, and ensures that after the wire tube 2 is glued to the inner wall of the built-in cavity 11, the battery can be installed in the built-in cavity 11, so that the battery is fixed by abutting against the wire tube 2 and the inner wall of the built-in cavity 11; by forming an arc-shaped structure matched with the wire tube 2 and the built-in cavity 11, the battery is fixed in the built-in cavity 11, and a battery holder is not needed, thereby simplifying the structure of the installation and fixation.

[0078] The technical scheme of the present application forms a frame body 1 with an internal cavity 11, a wire tube 2 for wiring, and a pressing jig 3.
