Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a cable and an electric vehicle. Background Technology

[0002] With the fast pace of life, electric vehicles such as electric bicycles, electric tricycles and electric motorcycles have become one of the main means of transportation for people's daily travel, and are often used for commuting, shopping and other scenarios.

[0003] In electric vehicles, wiring harness connectors are typically fixed to the vehicle body using a cable coil, which serves to organize and protect the wiring harness. In existing technology, the cable coil is usually connected to the vehicle body using threaded connectors such as screws. This connection method has the following problems:

[0004] Screw fixing requires drilling fixing holes in the coil. During the screw tightening process, the fixing holes on the coil are easily damaged, causing the coil to fail to be fixed and affecting the stability and safety of the wiring harness. In addition, screw fixing will increase the additional cost of the electric vehicle, including the cost of screws and corresponding fasteners.

[0005] Therefore, this application provides a new cable and electric vehicle to address the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cable coil to at least alleviate the technical problems of low stability and safety of cable coils on electric vehicle shells and high fixing costs in the prior art.

[0007] The purpose of this utility model is also to provide an electric vehicle to further alleviate the technical problems of low stability and safety of the coil fixing on the electric vehicle shell and high fixing cost in the prior art.

[0008] Based on the aforementioned first objective, this utility model provides a cable coil for fixing a wire harness connector to a vehicle body. The cable coil is provided with a first snap-fit ​​structure and a receiving cavity for accommodating the wire harness connector, and the vehicle body is provided with a second snap-fit ​​structure. The first snap-fit ​​structure and the second snap-fit ​​structure can be snapped together and fixed.

[0009] Furthermore, the first snap-fit ​​structure is a snap-fit ​​opening, and the second snap-fit ​​structure is a snap fastener, wherein the snap-fit ​​opening can snap and fix the snap fastener.

[0010] Furthermore, the buckle includes two interlocking parts spaced apart from each other;

[0011] When the buckle is engaged with the buckle, the buckle allows the two buckling parts to come close to each other, so that the buckle can be fitted over the two buckling parts. At this time, the two buckling parts are far apart from each other to secure the cable.

[0012] Furthermore, the fastening part includes a locking post, one end of which is fixed to the vehicle body along the length direction of the locking post, and the other end is provided with a locking protrusion;

[0013] When the buckle is engaged with the buckle, the buckle allows the two buckle protrusions of the two buckling parts to approach each other, so that the buckle passes through the buckle protrusions and is sleeved on the buckle posts of the two buckling parts. At this time, the buckle protrusions of the two buckling parts move away from each other to secure the coil.

[0014] Furthermore, along the circumference of the locking post, the circumferential surface of the locking post includes an arcuate area and a planar area, and the planar areas of the two fastening parts are arranged opposite to each other and spaced apart.

[0015] Furthermore, a friction part is provided on the arc-shaped surface area.

[0016] Furthermore, along the length of the locking post, the cross-section of the locking protrusion gradually decreases from the vehicle body outwards.

[0017] Furthermore, the protrusion is provided with a groove, which extends through the protrusion along the length of the post.

[0018] Furthermore, the coil is provided with a connecting part, and the first snap-fit ​​structure is disposed on the connecting part.

[0019] By adopting the above technical solution, the coil of this utility model has at least the following beneficial effects:

[0020] When fixing the wire harness connector to the vehicle body, first place the wire harness connector in the receiving cavity to fix the wire harness connector to the wire coil. Then, the first snap-fit ​​structure on the wire coil is snapped and fixed to the second snap-fit ​​structure on the vehicle body to fix the wire coil to the vehicle body, thereby fixing the wire harness connector to the vehicle body.

[0021] In other words, the coil in this embodiment is fixed to the vehicle body by snap-fit, replacing the screw fixing method in the prior art. Firstly, the snap-fit ​​fixing method does not require drilling fixing holes on the coil, so there is no problem of low fixing stability and safety due to the failure of fixing holes. Secondly, the coil is fixed to the vehicle body by snap-fit, thus eliminating the use of standard parts such as screws and corresponding fasteners, which reduces the material and labor costs of electric vehicles to a certain extent. Thirdly, the snap-fit ​​fixing method is faster and more convenient than screw fixing, improving the assembly efficiency of electric vehicles.

[0022] Based on the second objective mentioned above, this utility model provides an electric vehicle, which includes a vehicle shell, a wiring harness connector, and the aforementioned cable coil. The wiring harness connector can be disposed within the receiving cavity of the cable coil, and the first snap-fit ​​structure of the cable coil can be snapped and fixed with the second snap-fit ​​structure on the vehicle shell.

[0023] By adopting the above technical solution, the electric vehicle of this utility model has at least the following beneficial effects:

[0024] By incorporating the aforementioned cable coil into the electric vehicle, the electric vehicle gains all the advantages of the aforementioned cable coil, which will not be elaborated upon here. Attached Figure Description

[0039] Example 1

[0040] Please see Figure 1 and combined Figure 4 and Figure 6 This embodiment provides a cable coil 3, which is used to fix the wire harness connector 1 to the vehicle body 2. The cable coil 3 is provided with a first snap-fit ​​structure 31 and a receiving cavity for accommodating the wire harness connector 1. The vehicle body 2 is provided with a second snap-fit ​​structure 21. The first snap-fit ​​structure 31 and the second snap-fit ​​structure 21 can be snapped together and fixed.

[0041] When fixing the wire harness connector 1 to the vehicle body 2, the wire harness connector 1 is first placed in the receiving cavity to fix the wire harness connector 1 to the wire coil 3. Then, the first snap-fit ​​structure 31 on the wire coil 3 is snapped and fixed to the second snap-fit ​​structure 21 on the vehicle body 2 to fix the wire coil 3 to the vehicle body 2, thereby fixing the wire harness connector 1 to the vehicle body 2.

[0042] In other words, in this embodiment, the coil 3 is fixed to the vehicle body 2 by a snap-fit ​​method, replacing the screw fixing method in the prior art. Firstly, the snap-fit ​​fixing method does not require drilling fixing holes on the coil 3, so there is no problem of low fixing stability and safety due to the failure of fixing holes. Secondly, the coil 3 is fixed to the vehicle body 2 by a snap-fit ​​method, thus eliminating the use of standard parts such as screws and corresponding fasteners, which reduces the material cost and labor cost of electric vehicles to a certain extent. Thirdly, the snap-fit ​​fixing method is faster and more convenient than screw fixing, improving the assembly efficiency of electric vehicles.

[0043] Preferably, please refer to Figure 4 and Figure 6 In this embodiment, the first snap-fit ​​structure 31 is a snap-fit ​​opening, and the second snap-fit ​​structure 21 is a snap fastener. The snap-fit ​​opening can be snapped and fixed onto the snap fastener.

[0044] With this setup, when installing the cable coil 3, you only need to align the clip on the cable coil 3 with the buckle on the car body 2 and snap the clip into the buckle. The operation is simple, convenient, and saves time and effort.

[0045] In this embodiment, the coil 3 adopts a detachable snap-fit ​​connection method instead of screw fixation. The coil 3 can be installed and removed without tools through easy-to-operate pressing or snap-fit ​​method, which not only achieves a stable installation of the coil 3, but also avoids the problems caused by traditional screw fixation.

[0046] Preferably, please refer to Figure 4 and Figure 2 In this embodiment, the buckle includes two interlocking parts 22; when the buckle is engaged with the buckle, the buckle can bring the two interlocking parts 22 closer to each other, so that the buckle can be fitted over the two interlocking parts 22. At this time, the two interlocking parts 22 are far apart from each other to secure the wire coil 3.

[0047] With this configuration, the cable 3 in this embodiment presses the two fastening parts 22 together through the inner wall of the latch, so that the two fastening parts 22 are close to each other, making it easy for the latch to be fitted onto the outside of the two fastening parts 22. Then, the two fastening parts 22 move away from each other to reset. Thus, under the elastic pre-tightening force of the two fastening parts 22, the cable 3 achieves elastic self-locking, ensuring that the cable 3 is firmly fixed and not easy to loosen.

[0048] In other words, the cable 3 in this embodiment is fixed to the car body 2 by the dual action of elastic self-locking and buckle, providing a stable and reliable fixing effect for the cable 3.

[0049] Preferably, please refer to Figure 1 and Figure 4In this embodiment, the fastening part 22 includes a locking post 221. Along the length direction of the locking post 221, one end of the locking post 221 is fixed to the car body 2, and the other end is provided with a locking protrusion 222. When the locking slot is fastened to the buckle, the locking slot can make the locking protrusions 222 of the two fastening parts 22 approach each other, so that the locking slot passes through the locking protrusion 222 and is sleeved on the locking post 221 of the two fastening parts 22. At this time, the locking protrusions 222 of the two fastening parts 22 move away from each other to fasten and fix the wire coil 3.

[0050] This design locks the coil 3 in place using the latching protrusions 222 of the two fastening parts 22, providing sufficient clamping force while facilitating disassembly.

[0051] It should be noted that materials with appropriate elasticity and strength should be selected to manufacture the pins 221 and the protrusions 222, and necessary surface treatments should be performed to enhance their corrosion resistance and wear resistance.

[0052] Preferably, please refer to Figure 5 In this embodiment, along the circumference of the locking post 221, the circumferential surface of the locking post 221 includes an arc surface area 2211 and a planar area 2212. The planar areas 2212 of the two fastening parts 22 are arranged opposite to each other and spaced apart.

[0053] It should be added that the planar areas 2212 of the two fastening parts 22 are arranged opposite each other. That is, the planar areas 2212 of the two fastening parts 22 are close to each other, face to face, and have a gap between them. With this arrangement, the arcuate areas 2211 of the two fastening parts 22 are opposite to each other and are used to contact the inner wall of the bayonet on the wire package 3.

[0054] When the inner wall of the bayonet presses against the two fastening parts 22, the two fastening parts 22 move closer to each other. At this time, the two planar regions 2212 move closer to each other until the two planar regions 2212 come into contact. At this time, the inner wall of the bayonet causes the two fastening parts 22 to deform to the maximum extent. The setting of the planar regions 2212 can stably maintain the state of the two fastening parts 22 being pressed to the maximum deformation. The two fastening parts 22 are not easy to move relative to each other, which makes it easy for the bayonet to pass smoothly and steadily through the protrusion 222.

[0055] Preferably, in this embodiment, a friction part (not shown in the figure) is provided on the arc surface region 2211.

[0056] For example, the friction part is a friction groove or friction protrusion. The setting of the friction part provides anti-slip texture for the coil 3, increases the friction between the inner wall of the latch and the arc surface area 2211, and prevents the coil 3 from shifting during use.

[0057] Preferably, please refer to Figure 5In this embodiment, along the length of the locking post 221, the cross-section of the locking protrusion 222 gradually decreases from the car body 2 outwards.

[0058] For example, the latch 222 is shaped like a frustum or a truncated cone, with its larger end face close to the car body 2. This design allows the inner wall of the latch to fit into the smaller end face of the latch 222, while the outer surface of the latch 222 guides the fitting of the inner wall, facilitating the rapid assembly and installation of the coil 3 and improving assembly efficiency.

[0059] Preferably, please refer to Figure 5 In this embodiment, a groove 223 is provided on the protrusion 222, and the groove 223 extends through the protrusion 222 along the length of the post 221. The groove 223 reduces the outer diameter of the protrusion 222, further facilitating the insertion of the inner wall of the latch.

[0060] Preferably, please refer to Figure 2 In this embodiment, the coil 3 is provided with a connecting part 32, and a first snap-fit ​​structure 31 is provided on the connecting part 32. The first snap-fit ​​structure 31 is provided on the connecting part 32, so that the connecting part 32 is connected to the second snap-fit ​​structure 21 on the vehicle body 2. With this arrangement, when the first snap-fit ​​structure 31 is a snap-fit, the snap-fit ​​is not directly provided on the coil 3, thereby preventing the snap-fit ​​on the vehicle body 2 from interfering with the wire harness connector 1 in the receiving cavity of the coil 3 when the snap-fit ​​is engaged with the snap-fit, thus improving the reliability of the connection between the wire harness connector 1 and the coil 3.

[0061] Optionally, the connecting part 32 can be a connecting plate, connecting piece, or connecting block, etc., and its shape is not limited here.

[0062] Preferably, please refer to Figure 2 The body shell 2 is provided with connecting ribs 23, and the second snap-fit ​​structure 21 is connected to the body shell 2 through the connecting ribs 23. The setting of the connecting ribs 23 makes the second snap-fit ​​structure 21 more firmly and reliably installed on the body shell 2, thereby improving the stability of the connection between the coil 3 and the body shell 2.

[0063] Example 2

[0064] Embodiment 2 provides an electric vehicle, which includes the coil 3 of Embodiment 1.

The implementation method of the electric vehicle will be further described in detail below with reference to the accompanying drawings.

[0065] Please see Figure 1 and Figure 3The electric vehicle provided in this embodiment includes a vehicle shell 2, a wiring harness connector 1 and the aforementioned cable coil 3. The wiring harness connector 1 can be disposed in the receiving cavity of the cable coil 3, and the first snap-fit ​​structure 31 of the cable coil 3 can be snap-fitted and fixed with the second snap-fit ​​structure 21 on the vehicle shell 2.

[0066] It should be noted that the electric vehicles mentioned here can include electric bicycles, electric tricycles, and electric motorcycles, etc.

[0067] When assembling an electric vehicle, the wire harness connector 1 is first placed in the receiving cavity to fix the wire harness connector 1 to the wire coil 3. Then, the first snap-fit ​​structure 31 on the wire coil 3 is snapped and fixed to the second snap-fit ​​structure 21 on the vehicle shell 2 to fix the wire coil 3 to the vehicle shell 2, thereby fixing the wire harness connector 1 to the vehicle shell 2.

[0068] In other words, in the electric vehicle of this embodiment, the coil 3 is fixed to the vehicle shell 2 by a snap-fit ​​method, replacing the screw fixing method in the prior art. Firstly, the snap-fit ​​fixing method does not require drilling fixing holes on the coil 3, so there is no problem of low fixing stability and safety due to the failure of fixing holes. Secondly, the coil 3 is fixed to the vehicle shell 2 by a snap-fit ​​method, thus eliminating the use of standard parts such as screws and corresponding fasteners, which reduces the material cost and labor cost of the electric vehicle to a certain extent. Thirdly, the snap-fit ​​fixing method is faster and more convenient than screw fixing, improving the assembly efficiency of the electric vehicle.
