[0004] However, when fixing the wire body relative to the bicycle frame, it is necessary to install the buckle, the sheet metal part and / or the screw connection structure, and this fixing method is relatively cumbersome, so that the efficiency of fixing the wire body relative to the bicycle frame is relatively low.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] The bicycle frame provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] Figure 1 and Figure 2 This is a schematic diagram of the bicycle frame provided in an embodiment of this application. Figure 1 and Figure 2As shown, the bicycle frame includes a frame tube 1 and a cable clamp 2; the frame tube 1 is connected to a cable 5, at least a portion of the cable 5 is located inside the cavity of the frame tube 1; the cable clamp 2 is disposed inside the cavity of the frame tube 1, and both ends of the cable clamp 2 are connected to the inner wall of the frame tube 1, the aforementioned at least a portion of the cable 5 abuts against the target wall 11 of the frame tube 1 and the cable clamp 2, and the cable clamp 2 has a cable passage 21 for the aforementioned at least a portion of the cable 5 to pass through, the cable passage 21 causing the cable clamp 2 to be disconnected between its two ends, wherein the target wall 11 is the portion of the inner wall of the frame tube 1 located on one side of the cable clamp 2.

[0027] The bicycle frame can be at least a part of the frame of a bicycle (such as an electric bicycle or a non-electric bicycle), and the bicycle frame is used to connect to the cable 5 included in the bicycle. For example, the bicycle frame can be the front triangle frame used in electric bicycles or non-electric bicycles. The specific type of bicycle frame is not limited in this embodiment. The cable 5 is a cable installed on the bicycle frame. For example, the cable 5 can be a motor cable or a brake cable. The specific type of cable 5 is not limited in this embodiment. It should be noted that if the cable 5 is a motor cable, then the bicycle frame is at least a part of the frame of an electric bicycle.

[0028] During the assembly process based on the bicycle frame, the first end of the line 5 can be connected to the first end of the frame tube 1 (e.g., Figure 2 The A end of the tube is inserted into the cavity of the support tube 1, and then from the second end of the support tube 1 (e.g., the A end) .... Figure 2 The first end of the wire 5 is inserted through the second end of the frame tube 1 into the cavity of the frame tube 1, and then out through the first end of the frame tube 1. This application does not limit this embodiment. This article uses "inserting the first end of the wire 5 through the first end of the frame tube 1 into the cavity of the frame tube 1, and then out through the second end of the frame tube 1" as an example for explanation. At this time, both the first end and the second end of the wire 5 are located outside the frame tube 1, and the part of the wire 5 used to be installed in the cavity of the frame tube 1 (i.e., the above-mentioned at least part of the wire 5) is located in the cavity of the frame tube 1. Then, since the wire passage 21 causes the pressure member 2 to be disconnected between the two ends of the pressure member 2, the above-mentioned at least part of the wire 5 can be directly inserted from the wire passage 21 on the pressure member 2 into the space between the pressure member 2 and the target wall 11 of the frame tube 1, so that the above-mentioned at least part of the wire 5 abuts against the target wall 11 of the frame tube 1 and the pressure member 2. At this time, the wire 5 is fixed relative to the frame tube 1, and then the wire 5 is fixed relative to the bicycle frame.

[0029] In the embodiment of the present application, the bicycle frame comprises a frame tube 1 and a wire pressing piece 2 located in the lumen of the frame tube 1, and the wire pressing piece 2 is provided with a wire passing port 21, so that the wire pressing piece 2 is disconnected between the two ends of the wire pressing piece 2 due to the wire passing port 21. Therefore, during the assembly based on the bicycle frame, the wire body 5 can be first inserted through the frame tube 1 so that at least part of the wire body 5 is located in the lumen of the frame tube 1, and then the at least part of the wire body 5 is directly inserted into the target wall 11 between the wire pressing piece 2 and the frame tube 1 through the wire passing port 21 of the wire pressing piece 2, so that the wire body 5 can be fixed relative to the frame tube 1, and then the wire body 5 can be fixed relative to the bicycle frame. This fixing method is simple and fast, and the efficiency of fixing the wire body 5 relative to the bicycle frame is improved.

[0030] In addition, the wire pressing piece 2 in the present application makes the bicycle frame structure compact, does not need additional parts to fix the wire body 5, has high safety and reliability, good wire fixing effect, simple structure, and saves cost.

[0031] Optionally, as shown in Figure 1 , the first end and the second end of the wire body 5 are connected with other components of the bicycle outside the frame tube 1, for example, the wire body 5 is a motor wire, the first end of the wire body 5 can be connected with a motor, and the second end of the wire body 5 can be connected with a controller, which is not limited in the present application.

[0032] Optionally, the frame tube 1 can be at least part of the tube body of the bicycle frame, for example, as shown in Figure 1 , the frame tube 1 is part of the tube body of the bicycle frame, the first end of the frame tube 1 is in communication with other tube bodies of the bicycle frame, and the second end of the frame tube 1 is connected with a handlebar of the bicycle.

[0033] In one possible implementation, as shown in Figure 1 , the length direction of the wire passing port 21 is not parallel to the length direction of the frame tube 1, wherein the length direction of the wire passing port is the direction from the first port of the wire passing port to the second port of the wire passing port, the first port of the wire passing port is the port of the wire passing port close to the first end of the frame tube, and the second port of the wire passing port is the port of the wire passing port close to the second end of the frame tube.

[0034] For example, Figure 1 , the length direction of the wire passing port 21 of one wire pressing piece 2 (see the dashed line a in Figure 1 ) is not parallel to the length direction of the frame tube 1 (see the dashed line c in Figure 1 and Figure 2 ), Figure 1 , the length direction of the wire passing port 21 of another wire pressing piece 2 (see the dashed line b in Figure 1 ) is not parallel to the length direction of the frame tube 1.

[0035] Thus, since the length direction of the wire body 5 abutting between the pressing member 2 and the target wall 11 of the pipe 1 is substantially parallel to the length direction of the pipe 1, the length direction of the wire passing port 21 is not parallel to the length direction of the pipe 1, that is, the length direction of the wire passing port 21 is not parallel to the length direction of the wire body 5, the possibility of the wire body 5 abutting between the pressing member 2 and the target wall 11 of the pipe 1 being pulled out can be reduced, and the position stability of the wire body 5 relative to the pipe 1 is improved.

[0036] Optionally, the width of the wire passing port 21 is greater than or equal to the diameter of the wire body 5, so as to facilitate the wire body 5 passing through the wire passing port 21.

[0037] In a possible implementation, as shown in Figure 1 , the pressing member 2 is provided with a plurality of (two are taken as an example in the figure), the plurality of pressing members 2 are arranged along the length direction of the pipe 1; the length directions of the wire passing ports 21 on at least some different pressing members 2 are not on the same straight line.

[0038] For example Figure 1 , the length direction of the wire passing port 21 of one pressing member 2 (see the dashed line a in Figure 1 ) is not on the same straight line as the length direction of the wire passing port 21 of another pressing member 2 (see the dashed line b in Figure 1 ).

[0039] Thus, the length directions of the wire passing ports 21 on at least some different pressing members 2 are not on the same straight line, the possibility of the wire body 5 abutting between the pressing member 2 and the target wall 11 of the pipe 1 being pulled out can be reduced, and the position stability of the wire body 5 relative to the pipe 1 is improved.

[0040] In a possible implementation, as shown in Figure 1 , the pressing member 2 is a sheet, so that the sheet-shaped pressing member 2 occupies less space in the pipe 1, and more installation space can be provided for other components (such as a battery of an electric bicycle, etc.) for installation in the pipe 1.

[0041] In a possible implementation, as shown in Figure 1 , the first end of the pressing member 2 connected with the inner wall of the pipe 1 is one end of the pressing member 2 along the length direction of the pressing member 2, and the second end of the pressing member 2 connected with the inner wall of the pipe 1 is the other end of the pressing member 2 along the length direction of the pressing member 2.

[0042] Thus, in the present application, the scheme that both ends of the pressing member 2 along the length direction of the pressing member 2 are connected with the inner wall of the pipe 1 can enable more wire bodies 5 to abut between the pressing member 2 and the target wall 11 of the pipe 1, and more wire bodies 5 can be fixed by using a smaller pressing member 2.

[0043] In a possible implementation, as shown in Figure 1 The inner wall of the rack pipe 1 is provided with a first connecting strip 3 and a second connecting strip 4; the length direction of the first connecting strip 3 and the length direction of the second connecting strip 4 are both parallel to the length direction of the rack pipe 1, the first end of the wire pressing piece 2 is connected with the first connecting strip 3, and the second end of the wire pressing piece 2 is connected with the second connecting strip 4.

[0044] In this way, by arranging the first connecting strip 3 and the second connecting strip 4, the connection between the end of the wire pressing piece 2 and the inner wall of the rack pipe 1 can be reinforced.

[0045] Optionally, the first connecting strip 3 and the second connecting strip 4 can be integrally connected or fixedly connected with the rack pipe 1, the first end of the wire pressing piece 2 can be integrally connected or fixedly connected with the first connecting strip 3, and the second end of the wire pressing piece 2 can be integrally connected or fixedly connected with the second connecting strip 4.

[0046] For example, the rack pipe 1, the first connecting strip 3, the second connecting strip 4 and the wire pressing piece 2 can be integrally formed, the shape is controlled by a sand core, so that the first connecting strip 3 and the second connecting strip 4 are integrally connected to the inner wall of the rack pipe 1, the first end of the wire pressing piece 2 is integrally connected with the first connecting strip 3, and the second end of the wire pressing piece is integrally connected with the second connecting strip 4. In this way, the integrally formed rack pipe 1, the first connecting strip 3, the second connecting strip 4 and the wire pressing piece 2 can be completed without computer numerical control (CNC), saving processing time and cost, and also reducing the weight of the vehicle frame itself.

[0047] In a possible implementation, as shown in Figure 1 The length direction of the wire pressing piece 2 (see the dashed line d in Figure 1 ) is greater than or equal to 45 degrees with the length direction of the rack pipe 1 (see the dashed line c in Figure 1 ), and the angle between the length direction of the wire pressing piece 2 and the length direction of the rack pipe 1 is less than or equal to 90 degrees. In this way, while ensuring that the wire pressing piece 2 can stably abut and fix the wire body 5 in the rack pipe 1, the wire pressing piece 2 can also be as short as possible, saving materials and costs. Therefore, the angle between the length direction of the wire pressing piece 2 and the length direction of the rack pipe 1 is equal to 90 degrees, which is the most preferred, and can achieve the greatest degree of material saving and cost saving.

[0048] In a possible implementation, as shown in Figure 3 The thickness of the wire pressing piece 2 is greater than or equal to 3.5 millimeters, and the width of the wire pressing piece 2 is greater than or equal to 6 millimeters. In this way, not only can materials be saved, but also the possibility of the wire pressing piece 2 being extruded, deformed or even damaged can be reduced.

[0049] In a possible implementation, as shown in Figure 1As shown, an operating port 121 is provided through the non-target wall 12 of the support tube 1. The non-target wall 12 is the part of the tube wall of the support tube 1 located on the side of the pressure piece 2 away from the target wall 11.

[0050] During the assembly of the bicycle frame, the first end of the cable 5 can be inserted from the first end of the frame tube 1 into the portion of the frame tube 1 between the non-target wall 12 and the pressure member 2, and then exit from the second end of the frame tube 1. At this time, both the first and second ends of the cable 5 are located outside the frame tube 1, and the portion of the cable 5 intended to be installed inside the frame tube 1 (i.e., the aforementioned at least part of the cable 5) is located inside the frame tube 1 between the non-target wall 12 and the pressure member 2. Then, the aforementioned at least part of the cable 5 can be inserted through the operating port 121. Part of the wire 5 is directly inserted from the wire passage 21 on the wire clamping member 2 into the space between the wire clamping member 2 and the target wall 11 of the frame tube 1, so that at least part of the wire 5 abuts between the target wall 11 of the frame tube 1 and the wire clamping member 2. Then, other components (such as the battery of an electric bicycle) for installation in the frame tube 1 are installed between the wire clamping member 2 and the non-target wall 12 of the frame tube 1 through the operation port 121, so that the other components are installed in the frame tube 1. Thus, the setting of the operation port 121 facilitates the assembly based on the bicycle frame.

[0051] Optionally, such as Figure 1 As shown, within the cavity of the frame tube 1, the space between the non-target wall 12 and the pressure piece 2 is larger than the space between the target wall 11 and the pressure piece 2, which facilitates the passage of the connector of the wire 5 through the cavity of the frame tube 1 during assembly based on the bicycle frame.

[0052] Optional, such as Figure 1 As shown, a cover plate (not shown in the figure) for covering the operation port 121 can be provided at the operation port 121. The cover plate can be detachably connected to the support tube 1 or fixedly connected, etc. This application embodiment does not limit this.

[0053] In one possible implementation, such as ​ As shown, a partition plate (not shown in the figure) is also provided inside the cavity of the tube 1. The material of the partition plate can be plastic or the like. This application embodiment does not limit the material of the partition plate. The pressure piece 2 is located between the partition plate and the line body 5. The side of the partition plate near the pressure piece 2 is connected to the pressure piece 2. For example, the side of the pressure piece 2 away from the line body 5 is bonded to the partition plate by self-adhesive attached to the side of the partition plate near the pressure piece 2.

[0054] Therefore, the partition plate can cover the pressure piece 2 and the wire body 5 inside the cavity of the support pipe 1, thus improving the aesthetics of the inside of the support pipe 1.

[0055] It is to be noted that the relationship terms, such as first and second, are used only to differentiate one entity or operation from another entity or operation, and do not necessarily require or imply any actual such relationship or order between such entities or operations. Moreover, the terms "comprising", "including", or any other variant thereof are intended to cover a non-exclusive inclusion, such that processes, methods, articles, or apparatuses that comprise a list of elements are not required to include only those elements in the list, but can include other elements not expressly listed or inherent to such processes, methods, articles, or apparatuses. Without more limitations, an element defined by an "comprising" statement serves as a means plus function alternative.

[0056] Finally, it should be noted that the above merely illustrates the preferred embodiments of the present application, and is only used to explain the technical solutions of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
