Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an electric bicycle. In particular, it relates to an electric bicycle frame that can hide a battery in a middle tube. [Previous Art] A conventional electric bicycle, as disclosed in Japanese Patent No. M316210, includes a frame and a power supply device, and the frame is provided with a receiving groove for receiving the power supply device, wherein The accommodating groove may be formed in the middle pipe or the upper pipe; however, the power supply device is barely disposed on the outer side of the frame. 'The sun and rain will cause the service life to be reduced, and it is quite unattractive. Moreover, the accommodating The setting of the trough also affects the structural strength of the frame and therefore needs to be improved. SUMMARY OF THE INVENTION In view of the above-mentioned deficiencies, an object of the present invention is to provide an electric bicycle frame that can hide a battery in a middle tube, and the battery does not need to be exposed to the outside, but can improve the service life and increase the appearance of the frame without affecting. The strength of the car structure. For the purpose of the prior art, the electric bicycle frame of the present invention for hiding the battery in the middle tube comprises a frame body, a battery and a closing member, the frame body having a middle tube, wherein the inner portion of the tube is hollow Forming a chamber, the chamber is formed with an opening at the top end of the middle tube, the battery is received in the chamber of the frame body, and the closing member is disposed at the top of the tube 3 201215534 in the frame body The opening of the chamber is closed. In an embodiment of the present invention, the electric bicycle frame that can hide the battery in the middle tube further includes a tube and a bundle ring, and the tube body of the frame body further includes a receiving hole for the bottom of the seat tube. The end is inserted, and the receiving hole is located on the front side of the chamber, and extends in a direction parallel to the chamber, the collar is sleeved on the top end of the tube body of the frame body, and further, the frame body is The middle tube has a bump formed inside the chamber and abutting the bottom end of the battery. - In another embodiment of the invention, the closure member has a tubular shape with a top end and a bottom end, the top end being provided with a mat disposed thereon, the bottom end forming a slot for the body of the frame The top end of the tube is inserted therein, and a groove extends radially from the slot to the outside of the closure. The electric bicycle frame further includes a bundle of loops disposed at the bottom end of the closure. In another embodiment of the present invention, the bottom end of the closure member is formed with a slot for the battery to be fixed therein, and the bottom end of the closure member and the battery are commonly accommodated in the body of the frame body. In the room. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to explain the structure and features of the present invention in detail, the following three preferred embodiments are described with reference to the accompanying drawings, wherein: FIG. 2 is an exploded view of a first preferred embodiment of the present invention; a third view is a cross-sectional view of the first embodiment taken along line 3-3; and a fourth view is an exploded view of a second preferred embodiment of the present invention; 201215534 An exploded view of a third preferred embodiment of the present invention. Referring to the first to third figures, the electric bicycle frame 10 for hiding the battery in the middle tube provided by the first preferred embodiment of the present invention is compatible with a handle 12, a front fork 13, and a mat 14. A front wheel 15 and a rear wheel 16 are combined to form a bicycle. The electric bicycle frame 10 includes a frame body 20, a battery 30, a closure member 40, a tube 50, and a bundle of rings 60. The frame body 20 includes a middle tube 22, a lower tube 24, a rear upper fork 26 and a rear lower fork 28. The inner portion of the middle tube 22 is hollow and is formed with a mutually parallel chamber 221 and a receiving hole 222. The accommodating hole 223 is located on the front side of the chamber 221, and the two sides are respectively formed with an opening 223, 224 at the top end of the middle tube 22. In addition, the middle tube 22 has a protrusion 226 formed on the inner side of the chamber 221 A wall 'and a section 228 are formed at the top end of the middle tube 22'. The section 228 extends radially from the receiving hole 222 to the outside of the center tube 22. The battery 30 is received in the chamber 221 of the frame body 2, and its bottom end abuts against the inner bump 226 of the middle tube 22. The closure member 40 is a cover body and is inserted into the top end of the tube 22 in the frame body 2 to close the opening 223 of the chamber 221 so that the battery 30 can be completely hidden in the middle tube. 22 internal. The seat tube 50 has a top end 52 and a bottom end 54 for the seat cushion 14 to be fixed thereto, and the bottom end 54 is inserted into the middle tube 22 via the opening 224. Hole 222. The collar 60* is a -C-shaped bundle ring and is sleeved on the top end of the tube 22 in the frame body 2, and can be pressed to the outside of the middle tube 22, so that the seat 201215534 tube 50 and the middle tube 22 can be more closely combined. Since the closing member 4 封闭 can close the opening 223 of the chamber 221, the battery 30 can be completely hidden inside the middle tube 22, in addition to increasing the appearance, the battery 30 can be used without being exposed to the sun and rain. The improvement of the life span; furthermore, the combination structure of the battery 30 is placed inside the middle tube 22, so that the structure of the t official 22 can be maintained intact without affecting the structural strength of the frame 2 . According to the spirit of the present invention, the electric bicycle frame can be freely changed in structure. Referring to the fourth figure, the electric bicycle frame provided by the second preferred embodiment of the present invention and the foregoing provider are provided. Ratherly the same, the only difference is that the closure member 76, that is, the seat tube of the electric bicycle frame 70, is tubular and has a top end % and a bottom end 763. The top end 761 is provided for a mat. The bottom end 763 is formed with a slot 765 for the top end of the tube 721 of the frame body 72 to be inserted therein. The tube 721 is not provided with the above-mentioned solid hole, and the collar 78 is The sleeve 763 is formed at a bottom end 763 of the closure member 76. Further, the bottom end 763 of the closure member 76 is formed with a groove 767 which is radially extended from the slot 765 to the outside of the closure member. The closure member % bottom end 763 is more likely to abut the middle tube 72ι under the compression of the collar 78. Referring to FIG. 5, an electric bicycle frame (10) for hiding a battery in a middle tube according to a third preferred embodiment of the present invention also has a frame body 82, a battery 84, a closure member, and a bundle. The ring 88 is different in that the battery 84 is fixed in the slot of the closure member and is inserted into the frame body 82 together with the bottom end 863 of the closure member 86. The tube 201215534 821 housing 823 In the middle, the middle of the tube 821. And the bundle ring 88 is sleeved on the frame body 82 - the above description is only a detailed description and illustration of the preferred embodiment of the present invention. The embodiments are all included in the scope of the present invention, and any variations or modifications that can be easily considered by those skilled in the art of the present invention are covered by the scope of the patent.
