Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a wiring harness limiting mechanism and an electric vehicle. Background Technology

[0002] There are many electric vehicle control buttons on the handlebars of an electric bicycle, and there are multiple wiring harnesses between the handlebars and the vehicle body.

[0003] Currently, existing wiring harness limiting mechanisms include a mounting block welded to one side of the vehicle frame head tube. An arc-shaped plate is provided on one side of the mounting block. One end of the arc-shaped plate is connected to the mounting block, and a gap is left between the other end and the mounting block. An accommodating area is formed between the arc-shaped plate and the mounting block. The wiring harness is limited by inserting it into the accommodating area from the gap.

[0004] However, the above method can easily cause the wiring harness to come out of the housing area during the rotation of the handlebars, resulting in friction and scratches between the wiring harness and surrounding components, or even wire clamping. Utility Model Content

[0005] (a) The problem to be solved by this utility model is that during the rotation of the handlebars, the wire harness is easily detached from the receiving area, causing friction and scratching between the wire harness and the surrounding related parts, or even wire clamping.

[0006] (II) Technical Solution The present invention provides a wire harness limiting mechanism, comprising a first limiting member and a second limiting member; The first limiting member and the second limiting member are disposed opposite to each other, and the two ends of the first limiting member are respectively connected to the two ends of the second limiting member; A receiving cavity with openings at both ends is formed between the first limiting member and the second limiting member, and the receiving cavity is used to receive the wire harness.

[0007] According to one embodiment of the present invention, the wire harness limiting mechanism includes a connector; The two ends of the first limiting member are detachably connected to the two ends of the second limiting member via a connecting member.

[0008] According to one embodiment of the present invention, the first limiting member includes a first limiting body, and along the length direction of the wire harness, the first limiting body has a first flange on at least one side. A rounded corner is formed between the first flange and the first limiting body.

[0009] According to one embodiment of the present invention, the first limiting body includes a first arc-shaped portion and a first connecting portion; Both sides of the first arc-shaped portion are connected to the first connecting portion, and a rounded corner is formed between each first connecting portion and the first arc-shaped portion.

[0010] According to one embodiment of the present invention, the second limiting member includes a second limiting body, and along the length direction of the wire harness, the second limiting body has a second flange on at least one side. A rounded corner is formed between the second flange and the second limiting body.

[0011] According to one embodiment of the present invention, the second limiting body includes a second arc-shaped portion and a second connecting portion; The second arc-shaped portion is connected to the second connecting portion on both sides, and a rounded corner is formed between each second connecting portion and the second arc-shaped portion.

[0012] According to one embodiment of the present invention, the connecting member includes a fixing bolt; Each of the first connecting parts is provided with a screw hole, and each of the second connecting parts is provided with a through hole; The screw holes and the through holes correspond one-to-one, and the fixing bolt passes through the through hole and is screwed into the screw hole.

[0013] According to one embodiment of the present invention, the first connecting part includes a plate and a protrusion. The protrusion is connected to the side of the plate away from the second connecting part. The protrusion and the plate are respectively provided with a first threaded hole and a second threaded hole, and the first threaded hole and the second threaded hole are connected to form the threaded hole.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: like Figures 1-3 As shown, one embodiment of the present invention provides a wiring harness limiting mechanism, which is connected to one side of the vehicle frame head tube 5 and includes a first limiting member 1 and a second limiting member 2; The first limiting member 1 and the second limiting member 2 are arranged opposite to each other, and the two ends of the first limiting member 1 are respectively connected to the two ends of the second limiting member 2. A receiving cavity 4 with openings at both ends is formed between the first limiting member 1 and the second limiting member 2. The receiving cavity 4 is used to receive the wire harness.

[0022] By connecting the two ends of the first limiting member 1 to the two ends of the second limiting member 2 respectively, the periphery of the receiving cavity 4 formed between the first limiting member 1 and the second limiting member 2 is closed. When the wire harness is placed in the receiving cavity 4, the wire harness will not come out of the receiving cavity 4, and thus the wire harness will not rub or scratch against the surrounding related parts or even get stuck.

[0023] It should be noted that the openings at both ends of the receiving cavity 4 refer to the upper and lower ends.

[0024] Compared to some fixing methods that use strip-fixed wire harnesses, the accommodating cavity 4 has enough space to allow each connecting wire in the wire harness to move independently. Therefore, there will be no situation where the wire harness has insufficient space to stretch during turning, which would cause turning difficulties.

[0025] According to one embodiment of the present utility model, the first limiting member 1 includes a first limiting body, and along the length direction of the wire harness, the first limiting body has a first flange 11 on at least one side. A rounded corner is formed between the first flange 11 and the first limiting body.

[0026] According to one embodiment of the present invention, a first flange 11 is provided on both sides of the first limiting body along the length direction of the wire harness.

[0027] According to one embodiment of the present invention, the second limiting member 2 includes a second limiting body. Along the length direction of the wire harness, the second limiting body has a second flange 21 on at least one side. Preferably, the second limiting body has a second flange 21 on both sides. A rounded corner is formed between the second flange 21 and the second limiting body.

[0028] The first flange 11 and the first limiting body form a rounded corner (i.e. arc transition), which can protect the wire harness from wear and scratches when it comes into contact with the first limiting member 1, thus preventing the wire harness from being painted or worn.

[0029] Similarly, a second flange 21 is provided on both sides of the second limiting body, and the second flange 21 forms a rounded corner with the second body, which can protect the wire harness from wear caused by wire grinding when it is in long-term contact with the second limiting member 2.

[0030] According to one embodiment of the present invention, the first limiting body includes a first arc-shaped portion 12 and a first connecting portion 13; Both sides of the first arc-shaped portion 12 are connected to the first connecting portion 13, and a rounded corner is formed between each first connecting portion 13 and the first arc-shaped portion 12.

[0031] According to one embodiment of the present invention, the second limiting body includes a second arcuate portion 22 and a second connecting portion 23; The second arc-shaped portion 22 is connected to the second connecting portion 23 on both sides, and each second connecting portion 23 and the second arc-shaped portion 22 form a rounded corner.

[0032] The area enclosed between the first arc-shaped portion 12 and the second arc-shaped portion 22 is the receiving cavity 4. The first connecting portion 13 and the second connecting portion 23 correspond one-to-one and fit together.

[0033] Preferably, the limiting mechanism further includes a limiting rod and a limiting hole. The limiting rod is connected to the side of the first connecting part 13 near the second connecting part 23, and the limiting hole is opened on the second connecting part 23. The second limiting member 2 is placed on the side of the first limiting member 1, and the limiting rod is inserted into the corresponding limiting hole. This allows the first limiting member 1 and the second limiting member 2 to be limited before the second limiting member 2 and the first limiting member 1 are fixed.

[0034] According to one embodiment of the present invention, the wire harness limiting mechanism includes a connector 3; The two ends of the first limiting member 1 are detachably connected to the two ends of the second limiting member 2 via a connector 3.

[0035] Preferably, the connector 3 includes a fixing bolt 31; Each first connecting part 13 is provided with a screw hole, and each second connecting part 23 is provided with a through hole; The screw holes and through holes correspond one-to-one, and the fixing bolt 31 passes through the through hole and is screwed into the screw hole.

[0036] Preferably, one of the through holes on the second connecting part 23 is a round hole, and the other through hole on the second connecting part 23 is an oblong hole. When fixing the first limiting member 1 and the second limiting member 2, firstly, a fixing bolt 31 is threaded through the round hole and the corresponding screw hole, and then another fixing bolt 31 is threaded through the oblong hole and the corresponding screw hole. The oblong hole design means that the through hole on one of the second connecting parts 23 does not need to correspond exactly to the screw hole on the corresponding first connecting part 13, thus reducing the accuracy requirements for the hole position.

[0037] It should be noted that the first connecting part 13 includes a plate 131 and a protrusion 132 connected to each other. The protrusion 132 is located on the side of the plate 131 away from the second connecting part 23, allowing the plate 131 to fit snugly against the second connecting part 23, thus preventing wire jamming. The protrusion 132 and the plate 131 are respectively provided with a first threaded hole and a second threaded hole, which are connected to form a threaded hole. It should be understood that the protrusion 132 is designed to improve the stability of the fixing bolt 31 during screwing and the strength of the first connecting part 13, eliminating the need for overall thickening of the first connecting part 13 and thus reducing costs.

[0038] Optionally, connector 3 includes a locking bolt and a locking nut; Each first connecting part 13 has a first round hole, and each second connecting part 23 has a second round hole. The locking bolt passes through the first round hole and the second round hole in sequence and is screwed into the locking nut.

[0039] Optionally, one of the first connecting parts 13 and its corresponding second connecting part 23 are rotatably connected, and the other first connecting part 13 and its corresponding second connecting part 23 are connected by a fixing bolt 31, which can also fix the first limiting member 1 and the second limiting member 2.

[0040] Optionally, the connector 3 includes an elastic buckle, which engages the first connecting part 13 and the corresponding second connecting part 23. This does not deviate from the design concept of this utility model, and therefore should fall within the protection scope of this utility model.

[0041] According to one embodiment of this utility model, each of the two first flanges 11 is connected to an arc plate 14, which is fixedly connected to the head tube 5 of the frame. The curvature of the arc plate 14 matches the curvature of the outer wall of the head tube 5, facilitating welding and fixing. Preferably, the first limiting member 1 is made of metal, such as stainless steel or aluminum alloy, and the side wall of the arc plate 14 fits against the side wall of the head tube 5. The arc plate 14 is welded to one side of the head tube 5. The second limiting member 2 can be made of metal or plastic, etc.

[0042] The wire harness is placed on one side of the first arc-shaped part 12, and the second limiting member 2 is placed on one side of the first limiting member 1. At this time, the wire harness is located in the receiving cavity 4 formed by the first limiting member 1 and the second limiting member 2. The fixing bolt 31 is screwed through the corresponding through hole and the corresponding screw hole and screwed into place. After the first limiting member 1 and the second limiting member 2 are installed in place, the first connecting part 13 and the second connecting part 23 are tightly fitted together. The advantage of this is that it can prevent the wire harness from entering the gap between the first connecting part 13 and the second connecting part 23 and causing the wire harness to be pinched and damaged.

[0043] Example 2: An electric vehicle includes a wiring harness limiting mechanism, a head tube 5, a handlebar guard, and a rear panel 6, such as Figure 3 As shown, a rear panel 6 is connected to the lower side of the handlebar guard. The inner side of the rear panel 6 is equipped with a frame head tube 5 and a wiring harness limiting mechanism, which is connected to the side wall of the frame head tube 5. This design employs a structure where a first limiting component 1 is welded and a fixing bolt 31 is used to fix a second limiting component 2. This ensures the overall wiring harness limiting mechanism's accommodating cavity 4 is sealed while providing sufficient space. Furthermore, it effectively reduces friction between the wiring harness and the rear panel 6 and handlebar guard during operation, minimizing paint peeling from painted parts.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
