Description

一种用于电动自行车的车架中管和衬套的组合结构A combined structure of a tube and bushing in a frame of an electric bicycle

技术领域technical field

本发明涉及电动自行车领域，特别是涉及一种用于电动自行车的车架中管和衬套组合结构。The invention relates to the field of electric bicycles, in particular to a combined structure of a frame middle tube and a bushing for electric bicycles.

背景技术Background technique

在车架的高温处理或焊接过程中，往往会引起车架中管变形，导致鞍管无法插入中管。因此，需要在车架定型后重新对中管进行内径铰孔，以确保中管内径的正圆和平直。而对于内径有凸筋的中管来说，铰孔程序会导致凸筋被部分或全部铣掉，而且在凸筋上留下毛刺。During the high temperature treatment or welding process of the frame, the middle tube of the frame is often deformed, so that the saddle tube cannot be inserted into the middle tube. Therefore, it is necessary to re-ream the inner diameter of the center tube after the frame is shaped to ensure that the inner diameter of the center tube is perfectly round and straight. For midpipes with ribs on the inside diameter, the reaming procedure can cause the ribs to be partially or completely milled out and leave burrs on the ribs.

发明内容SUMMARY OF THE INVENTION

本发明的一个目的是要提供一种用于电动自行车的车架中管和衬套的组合结构，避免了车架中管再铰孔。An object of the present invention is to provide a combined structure of a frame middle tube and a bushing for an electric bicycle, which avoids re-reaming of the frame middle tube.

特别地，本发明提供了一种用于电动自行车的车架中管和衬套的组合结构，车架中管沿着轴向分为第一管部和第二管部；所述第一管部的内壁光滑，所述第二管部的内壁设置有凸筋；衬套沿着其母线开通槽，所述衬套的厚度大于或等于所述凸筋的凸起高度，所述衬套的长度小于或等于所述第一管部的长度；所述衬套放入所述中管内，并且，所述衬套的外壁紧贴所述第一管部的内壁。In particular, the present invention provides a combined structure of a frame tube and a bushing for an electric bicycle, the frame tube is divided into a first tube part and a second tube part along the axial direction; the first tube The inner wall of the second pipe part is smooth, and the inner wall of the second pipe part is provided with a convex rib; the bushing is opened with grooves along its generatrix, the thickness of the bushing is greater than or equal to the convex height of the convex rib, and the thickness of the bushing is The length is less than or equal to the length of the first pipe part; the bushing is put into the middle pipe, and the outer wall of the bushing is in close contact with the inner wall of the first pipe part.

优选的，所述衬套的顶部上沿设置为向外侧的翻边结构。Preferably, the upper edge of the top of the bushing is set as a flanging structure facing outward.

优选的，所述翻边结构的周向由座管束压紧，所述座管束通过螺丝与所述中管锁定。Preferably, the circumferential direction of the flanging structure is compressed by a seat tube bundle, and the seat tube bundle is locked with the middle tube by screws.

车架在高温处理或焊接过程中往往会引起中管变形，导致鞍管无法插入中管，从而需要在车架定型后重新对中管进行内径铰孔，以确保内径正圆和平直。而对于内径有凸筋的中管来说，铰孔程序会导致凸筋被部分铣掉，甚至被完全铣掉，而且在凸筋上留下毛刺。In the process of high temperature treatment or welding of the frame, the middle tube is often deformed, so that the saddle tube cannot be inserted into the middle tube, so it is necessary to re-ream the inner diameter of the middle tube after the frame is shaped to ensure that the inner diameter is perfectly round and straight. For midpipes with ribs on the inside diameter, the reaming procedure can cause the ribs to be partially milled out, or even completely milled, and leave burrs on the ribs.

本发明采用中管和衬套组合结构，将可变径的衬套插入中管的第一管部。由于衬套的厚度大于凸筋的高度，因此鞍管电池盒在插入车架中管时可以避开凸筋，从而避免了车架再铰孔，也保护了鞍管电池盒。同时，本发明还将衬套的上沿作外翻边处理，翻边被座管束压住，锁管束通过螺丝与车架中管锁定。这样当鞍管电池盒从中管抽出的时候，衬套可以避免被鞍管电池盒带出中管。The invention adopts the combined structure of the middle tube and the bushing, and inserts the variable diameter bushing into the first tube part of the middle tube. Since the thickness of the bushing is greater than the height of the rib, the saddle tube battery box can avoid the rib when inserted into the middle tube of the frame, thus avoiding the re-reaming of the frame, and also protecting the saddle tube battery box. At the same time, in the present invention, the upper edge of the bushing is treated with outer flanging, the flanging is pressed by the seat tube bundle, and the locking tube bundle is locked with the middle tube of the frame through screws. This way, the bushing can be prevented from being carried out of the middle tube by the saddle tube battery box when the saddle tube battery box is pulled out of the middle tube.

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。The above and other objects, advantages and features of the present invention will be more apparent to those skilled in the art from the following detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings.

The same reference numbers in the figures designate the same or similar parts or parts. It will be understood by those skilled in the art that the drawings are not necessarily to scale. In the attached picture:

图2是图1所示的衬套与中管结合的示意图；Figure 2 is a schematic view of the combination of the bushing and the middle pipe shown in Figure 1;

图3是中管、衬套以及座管束完全安装后的示意图。Figure 3 is a schematic view of the center tube, bushing and seat tube bundle fully installed.

图中各符号所表示的含义如下：The meanings of the symbols in the figure are as follows:

1-第一管部；2-第二管部；3-车架中管；4-衬套；5-翻边结构；6-通槽；7-凸筋；8-座管束；9-螺丝；10-鞍管电池盒。1- The first tube part; 2- The second tube part; 3- The middle tube of the frame; 4- Bushing; 5- Flanging structure; 6- Through groove; ; 10 - Saddle tube battery case.

具体实施方式Detailed ways

如图1所示，衬套4沿着其母线开通槽6，从而使得衬套4的直径随着槽口的大小变化而变化。衬套4的顶部上沿设置为向外侧的翻边结构5。As shown in FIG. 1 , the bushing 4 opens a slot 6 along its generatrix, so that the diameter of the bushing 4 varies with the size of the slot. The upper edge of the top of the bushing 4 is provided as a flanging structure 5 facing outward.

如图2所示，车架中管3沿着轴向分为第一管部1和第二管部2。第一管部1的内壁光滑，第二管部2的内壁设置有凸筋7。衬套4的长度小于或等于第一管部1的长度。衬套4放入车架中管3的第一管部1内，并且，衬套4的外壁紧贴第一管部1的内壁。As shown in FIG. 2 , the frame middle tube 3 is divided into a first tube part 1 and a second tube part 2 along the axial direction. The inner wall of the first pipe part 1 is smooth, and the inner wall of the second pipe part 2 is provided with a rib 7 . The length of the bushing 4 is less than or equal to the length of the first pipe portion 1 . The bushing 4 is put into the first tube portion 1 of the frame middle tube 3 , and the outer wall of the bushing 4 is in close contact with the inner wall of the first tube portion 1 .

由于衬套4的厚度大于或等于凸筋的凸起高度，因此，当鞍管电池盒10进入车架中管3时，能够有效地避开凸筋7，从而避免了鞍管电池盒10与凸筋7之间的碰擦。Since the thickness of the bushing 4 is greater than or equal to the raised height of the protruding ribs, when the saddle tube battery box 10 enters the frame middle tube 3, the protruding ribs 7 can be effectively avoided, thereby preventing the saddle tube battery box 10 and the The rubbing between the ribs 7.

如图2、3所示，由于衬套4具有翻边结构5，衬套4的翻边结构5朝外，翻边结构5被座管束8压紧。座管束8通过螺丝9与车架中管3锁定。As shown in FIGS. 2 and 3 , since the bushing 4 has a flanging structure 5 , the flanging structure 5 of the bushing 4 faces outward, and the flanging structure 5 is pressed by the seat tube bundle 8 . The seat tube bundle 8 is locked with the frame tube 3 by the screw 9 .

综上，本发明采用中管和衬套组合结构，将可变径的衬套插入中管的第一管部1中。由于衬套的厚度大于凸筋的高度，因此鞍管电池盒在插入车架中管时可以避开凸筋，从而避免了车架再铰孔，也保护了鞍管电池盒。同时，本发明还将衬套的上沿作外翻边处理，翻边被座管束压住，锁管束通过螺丝与车架中管锁定。这样当鞍管电池盒从中管抽出的时候，衬套可以避免被鞍管电池盒带出中管。To sum up, the present invention adopts the combined structure of the middle tube and the bushing, and inserts the variable diameter bushing into the first tube portion 1 of the middle tube. Since the thickness of the bushing is greater than the height of the rib, the saddle tube battery box can avoid the rib when inserted into the middle tube of the frame, thus avoiding the re-reaming of the frame, and also protecting the saddle tube battery box. At the same time, in the present invention, the upper edge of the bushing is treated with outer flanging, the flanging is pressed by the seat tube bundle, and the locking tube bundle is locked with the middle tube of the frame through screws. This way, the bushing can be prevented from being carried out of the middle tube by the saddle tube battery box when the saddle tube battery box is pulled out of the middle tube.

至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。By now, those skilled in the art will recognize that, although various exemplary embodiments of the present invention have been illustrated and described in detail herein, the present invention may still be implemented in accordance with the present disclosure without departing from the spirit and scope of the present invention. The content directly determines or derives many other variations or modifications consistent with the principles of the invention.
