TECHNICAL FIELD
[0001] The utility model relates to vehicle technical field, especially a lower guard plate structure, and simultaneously, the utility model relates to a vehicle with the lower guard plate structure. BACKGROUND
[0002] In the daily use of straddle type vehicles (including various motorcycles), the driving environment is complex and diverse. When the straddle type vehicle drives on the water road, the wheel rotation is easy to splash a large amount of water, and the water will directly impact the chassis part. A plurality of wire harness interfaces are arranged at the chassis, and the current common wire harness interface protection measure can resist the invasion of ordinary water vapor to a certain extent, but in the face of the impact of the large water flow splashed during driving, the existing protection structure is often difficult to effectively block the water, and it is extremely possible to cause short circuit and other faults, which seriously affects the normal operation of the motorcycle electrical system. At the same time, the overflow tank drain pipe and the carbon tank drain pipe on the straddle type vehicle will discharge liquid when working, and when the rear wheel passes through the discharged liquid, it is easy to cause the rear wheel to slip and even cause safety accidents, which affects the driving safety and control stability.

[0011] Further, the extension portion is gradually inclined forward from back to front in a direction away from the main body portion.
[0012] Further, the main body portion comprises a bottom plate, and side plates arranged along edges of the bottom plate, the side plates and the bottom plate forming a top-opened groove;
[0013] The bottom plate is provided with a water leakage hole in communication with the groove.
[0014] Further, the bottom plate is provided with a mounting hole, and the bottom plate is connected with the chassis wire harness support in the up-down direction of the vehicle through a threaded fastener penetrating in the mounting hole.
[0015] Further, the bottom plate is provided with a protrusion protruding into the groove, and the mounting hole is arranged on the protrusion; and / or,
[0016] The side plate and the bottom plate are provided with a reinforcing rib.
[0017] Further, the side plate is provided with a connecting column, and the side plate is connected with the chassis wire harness support in the front-rear direction of the vehicle through plug-in connection of the connecting column.
[0018] Further, the side plate comprises a first side plate arranged at the back side of the bottom plate, and a second side plate arranged at two opposite sides of the bottom plate.
[0019] The connecting column is arranged on the first side plate, the chassis wire harness support is provided with a connecting hole, and a rubber sleeve is embedded in the connecting hole, and the connecting column is inserted in the rubber sleeve in interference.
[0020] Further, in a direction close to the liquid discharge port, the bottom wall of the liquid collecting groove is gradually inclined downward.
[0021] Compared with the prior art, the utility model has the following advantages:
[0022] The lower guard plate structure is directly installed on the chassis wire harness support of the vehicle and is arranged below the wire harness assembly, so that the direct impact of mud, sand and other foreign matters splashed from the bottom during the driving of the vehicle on the wire harness can be effectively blocked, the risk of damage, short circuit and other faults of the wire harness can be effectively reduced, and the stable operation of the electrical system of the vehicle can be effectively ensured. Moreover, the liquid discharge port is arranged on the side of the lower guard plate, and the collected liquid is discharged to one side of the vehicle, so that the problem that the liquid is directly discharged between the front wheel and the rear wheel connecting lines in the traditional design to cause the rear wheel to slip can be effectively solved, the driving safety of the vehicle in the wet or drainage working condition can be improved, and the control stability during the riding process can be ensured.
[0023] By making the lower guard plate include a main body portion and an extension portion extending to one side of the main body portion, and making the sump include a sump body and a flow guide channel provided on the extension portion, the sump forms a more directed liquid transport path. Compared with directly draining liquid from the single sump body, the flow guide channel can better guide the liquid to one side of the vehicle, thereby effectively ensuring that the liquid is far away from the wheel contact area, and further avoiding wheel skidding.
[0024] When the vehicle is driving forward, the liquid drained from the carbon can and the water overflow can has a forward movement tendency under the action of inertia. By gradually setting the extension portion from rear to front to be inclined forward, the physical characteristics can be met, so that the liquid can flow along the inclined surface to the drain under the double action of gravity and inertia, the drainage efficiency can be better improved, the liquid retention time on the lower guard plate can be reduced, thereby reducing the risk of water corrosion of the chassis or causing component short circuit.
[0025] By making the main body portion be surrounded by the bottom plate and the side plate provided along the edge thereof to form a groove structure with a top opening, a relatively closed protective space can be provided for the wire harness assembly. Compared with only relying on the planar lower guard plate, this structure can block the invasion of mud, water, sand and other foreign matters to the wire harness from multiple directions, thereby enhancing the protection strength of the wire harness and reducing the risk of damage to the wire harness. The water leakage hole provided on the bottom plate and communicating with the groove can avoid accumulation of liquid in the groove, prevent liquid corrosion of the wire harness, and prolong the service life of the wire harness.
[0026] By providing mounting holes on the bottom plate and connecting the bottom plate and the chassis wire harness support in the up-down direction of the vehicle by using threaded fasteners, the lower guard plate can be stably installed on the chassis wire harness support due to the strong fastening force of the threaded connection, thereby continuously and effectively playing its protective role on the wire harness and its collection and discharge function on the liquid. Moreover, the threaded connection is relatively simple in installation and disassembly, and is convenient to disassemble.
[0027] By providing a protrusion protruding into the groove on the bottom plate, and providing the mounting hole on the protrusion, the mounting hole can be higher than the planar portion of the bottom plate, which can prevent the liquid from directly soaking the mounting hole and the threaded fastener, and reduce the possibility of loosening or damage of the fastener due to water erosion, rust and other problems. At the same time, the setting of the protrusion can also improve the structural strength of this part of the bottom plate, thereby further improving the setting stability of the lower guard plate on the chassis wire harness support. By providing a reinforcing rib between the side plate and the bottom plate, the structural strength of the lower guard plate can be improved, which can effectively prevent the lower guard plate from deforming, thereby providing reliable protection for the wire harness.
[0028] The side plate is connected to the chassis wire harness support through the connecting column along the front-rear direction of the vehicle, and is connected to the chassis wire harness support through the mounting hole in the bottom plate along the up-down direction of the vehicle, so that a multi-directional connection mode is formed, the setting firmness of the lower guard plate on the chassis wire harness support is further improved, and the protection of the wire harness and the liquid collecting and discharging functions are further ensured.
[0029] By inserting the connecting column into the rubber sleeve of the connecting hole of the chassis wire harness support, the interference connection between the connecting column and the chassis wire harness support is facilitated, and when the lower guard plate needs to be disassembled for maintenance or replacement, the connecting column can be easily pulled out of the rubber sleeve, so that the lower guard plate is convenient to maintain and replace.
[0030] In the direction close to the liquid discharge port, the bottom wall of the liquid collecting groove gradually inclines downward, so that the principle of gravity can be fully utilized. When the carbon tank drain pipe and / or the overflow tank drain pipe discharges liquid, or the water splashed at the bottom during driving flows into the liquid collecting groove, the liquid will quickly flow to the liquid discharge port under the guidance of the inclined bottom wall, avoiding accumulation in the liquid collecting groove, which can greatly improve the drainage efficiency and reduce the corrosion risk of the liquid residue on the lower guard plate and chassis components. At the same time, it can also effectively prevent the phenomenon of liquid backflow.
[0031] Another purpose of the utility model is to provide a vehicle, the vehicle is straddle type vehicle, and the vehicle is equipped with the lower guard plate structure as described above.
[0032] The lower guard plate structure can better protect the chassis wire harness and other components, effectively prevent water splashed at the bottom during driving from entering the wire harness interface, thereby effectively reducing the vehicle electrical system problems caused by wire harness failure, and improving the reliability and safety of the vehicle. In addition, the design of the liquid collecting groove and the liquid discharge port of the lower guard plate can guide the liquid discharged from the overflow tank drain pipe and the carbon tank drain pipe to one side of the vehicle body, avoiding the rear wheel from slipping when passing through the discharged liquid, which can effectively improve the driving stability and control stability of the vehicle in wet or drainage working conditions. Moreover, the wire harness protection and liquid drainage functions are integrated on the lower guard plate, which can make the vehicle chassis structure more compact and reasonable.

[0048] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.
[0049] In the description of the utility model, it should be noted that the orientation words such as 'up, down, left, right, front, back' used in the embodiment are defined with the up-down direction, left-right direction and front-back direction of the automobile as the reference. Among them, the up-down direction of the automobile is also the height direction (Z direction) of the automobile, the front-back direction of the automobile is also the length direction (X direction) of the automobile, and the left-right direction of the automobile is also the width direction (Y direction) of the automobile. In addition, the terms 'first' and'second' are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0050] In addition, in the description of the utility model, unless otherwise expressly limited, the terms "mounting", "connecting", "connection", "connector" should be understood broadly. For example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate media, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with specific circumstances.
[0051] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0052] For straddle type vehicle, when it runs on the water road surface, the wheel rotation is easy to splash a large amount of water and directly impact the chassis part, and the chassis is arranged with numerous wire harness interfaces, the existing protection structure is often difficult to effectively block the water, and it is extremely possible to cause short circuit and other faults. At the same time, the overflow tank drain pipe 4 and the carbon tank drain pipe 3 of the straddle type vehicle will discharge liquid when working, and the discharged liquid is usually directly discharged to the ground, and the discharge position is usually between the front and rear wheel contact point connecting lines. When the rear wheel passes through these discharged liquids, the friction between the wheel and the ground will be sharply reduced due to the existence of the liquid, and then the rear wheel will slip, which will affect the driving stability and increase the control difficulty.
[0053] Therefore, the utility model provides a novel lower guard plate structure, which is applied to the straddle type vehicle and comprises a lower guard plate 1 mounted on the chassis wire harness support 2 in the vehicle. Wherein, the lower guard plate 1 is arranged below the wire harness assembly 5, and a liquid collecting groove K and a liquid discharge port in communication with the liquid collecting groove K are arranged on the lower guard plate 1. Moreover, the liquid collecting groove K is arranged corresponding to the carbon tank drain pipe 3 and / or overflow tank drain pipe 4 on the vehicle, and the liquid discharge port is located at the side of the lower guard plate 1 and is used for discharging the liquid in the carbon tank drain pipe 3 and / or overflow tank drain pipe 4 to one side of the vehicle.
[0054] The lower guard plate structure of the embodiment can effectively block the direct impact of the mud, sand and other foreign matters splashed at the bottom of the vehicle during driving on the wire harness, effectively reduce the risk of damage, short circuit and other faults of the wire harness, and effectively guarantee the stable operation of the electrical system of the vehicle. Moreover, by arranging the liquid discharge port at the side of the lower guard plate 1 and discharging the collected liquid to one side of the vehicle, the problem that the rear wheel slips due to the direct discharge of the liquid between the front and rear wheel contact point connecting lines in the traditional design can be effectively solved, the driving safety of the vehicle in the wet or drainage working condition can be improved, and the control stability during riding can be ensured.
[0055] Based on the above overall introduction, one exemplary structure of the lower guard plate structure of the embodiment is described with reference toFigures 1 to 6 As shown in FIG. 1, the lower guard plate 1 extends along the left-right direction of the vehicle and is arranged correspondingly to the carbon canister drain pipe 3 and the overflow canister drain pipe 4, so that the liquid drained by the carbon canister drain pipe 3 and the overflow canister drain pipe 4 can be drained to one side of the vehicle through the liquid drain port of the lower guard plate 1. The arrangement of the chassis wire harness support and the carbon canister drain pipe 3 and the overflow canister drain pipe 4 can refer to the prior art.
[0056] In order to further improve the use effect, as shown in FIG. 2, the bottom wall of the liquid collecting groove K gradually inclines downward along the direction close to the liquid drain port. By such arrangement, the principle of gravity can be fully utilized. When the carbon canister drain pipe 3 and / or the overflow canister drain pipe 4 drain liquid, or the water splashed on the bottom during driving flows into the liquid collecting groove K, the liquid will quickly flow to the liquid drain port under the guidance of the inclined bottom wall, avoiding accumulation in the liquid collecting groove K. Compared with the liquid collecting groove K with a flat bottom, the drainage efficiency is greatly improved, the risk of liquid residue corroding the lower guard plate 1 and the chassis components is reduced, and the chassis can be kept in a relatively dry environment for a long time. Figure 4
[0057] As a preferred embodiment, the lower guard plate 1 comprises a main body part 1a and an extension part 1b extending to one side of the main body part 1a. The liquid collecting groove K comprises a groove body arranged on the main body part 1a and a flow guide channel arranged on the extension part 1b. The flow guide channel is in communication with the groove body, and the liquid drain port is arranged at one end of the flow guide channel away from the groove body.
[0058] By arranging the extension part 1b and adding the flow guide channel in communication with the groove body of the main body part 1a, a continuous and more guided liquid transmission path can be formed. Compared with direct liquid drainage of a single groove body, the flow guide channel can better guide the liquid away from the wheel contact area, which can further reduce the risk of wheel skidding caused by liquid accumulation.
[0059] As shown in FIG. 3, as a specific embodiment, the groove body is arranged on the side of the main body part 1a close to the extension part 1b. As shown in FIG. 4, as another specific embodiment, the groove body is arranged on the side of the main body part 1a away from the extension part 1b. Figures 1 to 3 Figure 3 As shown in FIG. 5, the groove body is substantially rectangular, and the distance between the two side walls of the groove body gradually decreases along the direction close to the flow guide channel in the left-right direction of the vehicle. By such design, the liquid can be more effectively guided to the flow guide channel, and then drained through the liquid drain port, improving the drainage efficiency of the entire liquid collecting groove K and reducing the liquid residue in the groove body.
[0060] In addition, as shown in FIG. 6, the groove body is substantially rectangular, and the distance between the two side walls of the groove body gradually increases along the direction close to the flow guide channel in the left-right direction of the vehicle. Figure 3 As a further embodiment, as shown in FIG. 1, the extension part 1b is gradually inclined forward from back to front in the direction away from the main body part 1a. When the vehicle is moving forward, the water splashed from the bottom and the liquid discharged from the carbon tank and the overflow tank have a tendency to move forward under the action of inertia. By designing the extension part 1b to be gradually inclined forward from back to front, the physical characteristics can be better adapted, so that the liquid can flow more smoothly along the inclined surface to the liquid discharge port under the action of gravity and inertia, the drainage efficiency can be improved, the liquid retention time on the lower guard 1 can be reduced, and the risk of water corrosion of the chassis or short circuit of the components can be reduced.
[0061] In addition, as a preferred embodiment, the main body part 1a and the extension part 1b are integrally formed, and can be made of nylon. Compared with the separate arrangement of the main body part 1a and the extension part 1b, the structure can provide the lower guard 1 with higher structural strength, which not only makes the installation more convenient and reduces the risk of failure caused by loose connection of components, but also can uniformly disperse stress when the impact force from the bottom is borne, thereby improving the durability of the lower guard 1.
[0062] Referring to Figures 1 to 3 As a preferred embodiment, as shown in FIG. 1, the main body part 1a of the embodiment includes a bottom plate 101 and side plates arranged along the edges of the bottom plate 101, the side plates and the bottom plate 101 form a recess with an open top, and the bottom plate 101 is provided with a water leakage hole 1012 communicating with the recess. By forming a recess structure with an open top by the bottom plate 101 and the side plates arranged along the edges thereof, a relatively closed protection space can be provided for the wire harness assembly 5.
[0063] Compared with the planar lower guard 1 alone, this structure can block the invasion of foreign matters on the wire harness from multiple directions, can enhance the protection of the wire harness, can reduce the risk of damage to the wire harness, and can ensure the stable operation of the electrical system of the vehicle. In addition, by providing the water leakage hole 1012 on the bottom plate 101 and communicating with the recess, when water or other liquid enters the recess, the water leakage hole 1012 can quickly drain the liquid by gravity, avoiding the accumulation of liquid in the recess, reducing the possibility of corrosion of the wire harness, and prolonging the service life of the wire harness.
[0064] Specifically, as shown in Figure 1 and Figure 2 The bottom plate 101 includes a middle part arched into the recess and side parts arranged on both sides of the middle part. The groove body is arranged on the middle part and one side of the side part and is formed by the bottom plate 101 itself protruding downward.
[0065] The bottom plate 101 of the present embodiment has the above structure, which can provide good structural strength, thereby preventing the bottom plate 101 from being deformed by force, and facilitating the protection of the wiring harness assembly 5. In addition, in order to further improve the structural strength of the bottom plate 101, as shown in Figure 2 the bottom plate 101 is provided with a reinforcing rib between the protruding part of the groove body and the planar part thereof, thereby further improving the structural strength of the lower guard 1 and preventing the groove body from being deformed by the gravity of the liquid.
[0066] At this time, in order to mount the lower guard 1 on the chassis wiring harness support 2, as a specific embodiment, as shown in Figure 1 and Figure 3 the bottom plate 101 is provided with a mounting hole 10111, and the bottom plate 101 is connected to the chassis wiring harness support 2 in the up-down direction of the vehicle by a threaded fastener (such as a bolt, nut, etc.) passing through the mounting hole 10111. By providing the mounting hole 10111 on the bottom plate 101 and connecting the bottom plate 101 to the chassis wiring harness support 2 in the up-down direction of the vehicle by a threaded fastener (such as a bolt, nut, etc.), a stable and reliable connection effect can be provided.
[0067] In addition, the threaded connection has strong fastening force, and even if the vehicle encounters complex conditions such as bumps and vibrations during driving, the lower guard 1 can be stably mounted on the chassis wiring harness support 2 and is not prone to loosening or falling off, thereby continuously and effectively playing its protective role for the wiring harness and its collection and discharge functions for the liquid. In addition, the threaded connection is relatively simple to install and remove, and can be completed using common tools (such as a wrench, etc.).
[0068] Further, as shown in Figure 1 the bottom plate 101 is provided with a protrusion 1011 protruding into the recess, and the mounting hole 10111 is provided on the protrusion 1011. The provision of the protrusion 1011 can raise the mounting hole 10111, making it higher than other parts of the bottom plate 101. When water or other liquid enters the recess, the protrusion 1011 can prevent the liquid from directly soaking the mounting hole 10111 and the threaded fastener, reducing the possibility of loosening or damage of the fastener due to water erosion, rusting, etc., thereby ensuring that the lower guard 1 is stably connected to the chassis wiring harness support 2 for a long time. At the same time, the provision of the protrusion 1011 can also improve the structural strength of this part of the bottom plate 101, thereby improving the connection strength between the bottom plate 101 and the chassis wiring harness support 2.
[0069] At this time, in order to further improve the installation firmness of the lower guard plate 1, a connecting column 1021 is arranged on the side plate, and the side plate is connected to the chassis wire harness support 2 through the connecting column 1021 along the front-rear direction of the vehicle. This structure, in combination with the above-mentioned connection between the bottom plate 101 and the chassis wire harness support 2 along the up-down direction of the vehicle, can form a multi-directional connection between the lower guard plate 1 and the chassis wire harness support 2, better resist external forces from various directions, reduce the possibility of loosening and displacement of the lower guard plate 1, and help ensure that the protection of the wire harness and the collection and discharge functions of the liquid are always stable and reliable.
[0070] As a specific embodiment, as shown in Figure 1 , the side plate includes a first side plate 102 arranged at the rear side of the bottom plate 101, and a second side plate 103 arranged at both opposite sides of the bottom plate 101. That is, the groove formed on the lower guard plate 1 is open at the top and the front side, and for this purpose, as a specific embodiment, as shown in Figure 3 , the water leakage hole 1012 of the present embodiment is arranged at one end of the bottom plate 101 close to the first side plate 102, and is four spaced along the length direction of the first side plate 102.
[0071] In this way, the liquid entering the groove can be effectively discharged through the water leakage hole 1012, avoiding the accumulation of liquid in the groove, and reducing the risk of corrosion of chassis components and wire harness caused by accumulated water. Moreover, the four water leakage holes 1012 spaced along the length direction of the first side plate 102 ensure the uniformity of drainage, and the multiple water leakage holes 1012 disperse the drainage, avoiding the drainage problems or blockage that may occur in a single water leakage hole 1012. It should be noted here that the arrangement position and number of the water leakage hole 1012 can be adjusted accordingly according to design requirements.
[0072] In addition, as shown in Figure 1 , the connecting column 1021 is arranged on the first side plate 102, the chassis wire harness support 2 is provided with a connecting hole, and a rubber sleeve 201 is embedded in the connecting hole, and the connecting column 1021 is inserted into the rubber sleeve 201 with interference. By inserting the connecting column 1021 into the rubber sleeve 201 with interference, not only can reliable connection fastening force be provided to stably install the lower guard plate 1 on the chassis wire harness support 2, but also threaded fasteners can be saved, and connection is facilitated. Moreover, the rubber sleeve 201 is usually made of rubber, which has a certain elasticity. During vehicle driving, the elasticity of the rubber sleeve 201 can play a buffering role, absorbing and dispersing these shock energies, reducing the rigid collision and friction between the lower guard plate 1 and the chassis wire harness support 2, thereby avoiding connection loosening or component damage caused by long-term vibration, and prolonging the service life of the lower guard plate 1 and the chassis wire harness support 2.
[0073] In addition, the elasticity of the rubber sleeve 201 also makes it relatively easy to pull the connecting column 1021 out of the rubber sleeve 201 when the lower guard 1 needs to be disassembled for maintenance or replacement. Compared with some permanent or very tight connection methods, this design ensures the stability of the connection while taking into account the convenience of maintenance, reducing the difficulty and time cost of maintenance personnel, and improving the maintainability of the vehicle.
[0074] As a specific embodiment, the longitudinal section of the rubber sleeve 201 is generally H-shaped, and a clamping groove is formed in the middle of the rubber sleeve 201 along the circumferential direction. The rubber sleeve 201 is clamped on the edge of the connecting hole through the clamping groove. Since the rubber sleeve 201 has a certain elasticity, by arranging the rubber sleeve 201 in the connecting hole, the interference fit connection between the connecting column 1021 and the wire harness support can be easily achieved.
[0075] It should be noted that the shape of the rubber sleeve 201 is not limited to the above structure, as long as it can be arranged in the connecting hole and form an interference fit with the connecting column 1021. In addition, the rubber sleeve 201 can also not be arranged in the connecting hole, and the connecting column 1021 can be directly connected with the connecting hole in an interference fit.
[0076] In addition, as a further embodiment, as shown in Figure 1 Two connecting columns 1021 are arranged on the first side plate 102. In this way, the connection firmness between the lower guard 1 and the chassis wire harness support 2 can be further improved. It should be understood that the number of connecting columns 1021 is not limited to two as shown in Figure 1 It can also be one or more.
[0077] In addition, in order to further improve the structural strength of the lower guard 1, a reinforcing rib 104 can also be arranged between the side plate and the bottom plate 101. As shown in Figure 3 In this embodiment, a reinforcing rib 104 is arranged between the first side plate 102 and the bottom plate 101, and the reinforcing rib 104 is two reinforcing ribs arranged along the length direction of the first side plate 102. It should be noted that the number of reinforcing ribs 104 can be adjusted according to design requirements. In addition to arranging the reinforcing rib 104 between the first side plate 102 and the bottom plate 101, the reinforcing rib 104 can also be arranged between the second side plate 103 and the bottom plate 101, or the reinforcing rib 104 can be arranged between the first side plate 102 and the bottom plate 101 and between the second side plate 103 and the bottom plate 101.
[0078] Based on the above overall description, the lower guard plate structure of the embodiment can effectively block the direct impact of mud, sand and other foreign matters splashed by the bottom of the vehicle during driving on the wire harness, effectively reduce the risk of damage, short circuit and other faults of the wire harness, and effectively ensure the stable operation of the electrical system of the vehicle. Moreover, it can effectively solve the problem of rear wheel slipping caused by direct liquid drainage between the front and rear wheel grounding connection lines in the traditional design, improve the driving safety of the vehicle in wet or drainage conditions, and help ensure the control stability during riding. Moreover, the lower guard plate 1 is installed below the chassis, which will not be affected by other parts of the vehicle, but can better protect the chassis.
[0079] In addition, the embodiment also relates to a vehicle, which is a straddle type vehicle, and the vehicle is provided with the above lower guard plate structure.
[0080] The vehicle of the embodiment can better protect the chassis wire harness and other components, effectively prevent water splashed from the bottom during driving from entering the wire harness interface, thereby effectively reducing the vehicle electrical system problems caused by wire harness failure, and improving the reliability and safety of the vehicle.
