[0002] The deflector is an air guide device installed on the top of the cab of a truck or tractor. Its main function is to effectively reduce the air resistance of the truck when it is running at high speed and reduce fuel consumption. During the transportation of cargo, the height of the cargo is higher than the cab, and there is a height difference and a certain gap, which makes the appearance of the whole vehicle discontinuous and the streamline poor. When the vehicle is running at high speed, when the airflow above the cab hits the upper part of the front of the closed compartment, a large height difference is generated from the front edge of the compartment roof, and the air resistance coefficient value increases accordingly. Therefore, it is very necessary to install a deflector on the vehicle.

[0003] The existing deflector is generally a "U"-shaped structure, including a top plate and side plates arranged on both sides of the top plate along the left and right directions. The deflector is installed on the rear side of the cab. However, the side plates are fixed with fixed brackets. After assembly, the side plates cannot be turned over. The side plates will occupy the space between the rear enclosure of the cab and the traction seat, affecting the convenience of users getting on and off the chassis workbench. Utility Model Content

[0038] See also Figure 1 The deflector side plate and deflector cover assembly provided by the utility model are now described. The deflector side plate includes a first plate body 1, a second plate body 2 and a hinge assembly. The first plate body 1 is connected to the vehicle body; the second plate body 2 is located below the first plate body 1; the hinge assembly is respectively connected to the first plate body 1 and the second plate body 2, so that the second plate body 2 is connected to the first plate body 1 by rotating around a first axis, and the first axis extends in the front-rear direction.

[0039] Compared with the prior art, the deflector side plate provided by the utility model is connected to the first plate body 1 by rotating the second plate body 2 around the first axis through a hinge assembly. When the vehicle is driving normally, the first plate body 1 and the second plate body 2 are located in the same plane. When it is necessary to enter the chassis workbench, the second plate body 2 is rotated around the first axis, and the user can enter the chassis workbench from the clearance space formed by the rotation of the second plate body 2. The utility model is equivalent to the solution of the deflector side plate as an integrated structure in the prior art. There is no need to flip or move the deflector side plate as a whole, which facilitates the user to enter and exit the chassis workbench. Moreover, only the second plate body 2 needs to be rotated. The volume and weight of the second plate body 2 are both smaller than the entire deflector side plate, which is not only convenient to operate, but also reduces the workload.

[0040] Optionally, the hinge assembly includes a hinge and a spring, which has a preload force to keep the second plate 2 and the first plate 1 in the same plane. The solution in this embodiment can prevent the second plate 2 from shaking randomly during driving in the car and affecting the diversion effect.

[0041] Optionally, the hinge assembly has a limiting structure so that the maximum flipping angle of the second plate body 2 is 90°, that is, when the second plate body 2 is perpendicular to the first plate body 1, the second plate body 2 cannot continue to rotate.

[0042] Optionally, the hinge assembly is a damping hinge to avoid the problem of increased resistance caused by random shaking of the second plate body 2 during driving of the vehicle, thereby ensuring the stability of the second plate body 2.

[0043] In some embodiments, see Figures 1 to 3 The guide side plate also includes a limit member 3 connected to the first plate body 1, and the limit member 3 has a limit portion extending downward to the second plate body 2. When the second plate body 2 and the first plate body 1 are located in the same plane, the limit portion of the limit member 3 abuts against the second plate body 2 in the inner and outer directions.

[0044] The stopper 3 can make the second plate 2 rotate only inward or outward, ensuring the stability of the second plate 2 during normal driving of the vehicle. In addition, the stopper portion of the stopper 3 abuts against the second plate 2, and the angle at which the second plate 2 and the first plate 1 are located in the same plane can be accurately found when the second plate 2 is rotated, avoiding the problem of the second plate 2 and the first plate 1 forming an angle due to excessive or insufficient rotation angle, thereby increasing the wind resistance during driving of the vehicle.

[0045] Optionally, the first plate body 1 is provided with a first connection hole, the limiting member 3 is provided with a second connection hole adapted to the first connection hole, and a connection member is inserted into the first connection hole and the second connection hole. The connection member may be a threaded member or a clamping member.

[0046] In some embodiments, see Figures 1 to 3 The second plate body 2 is provided with a clamping member 4, and the limiting member 3 is provided with a clamping hole for clamping with the clamping member 4, and the clamping member 4 is partially located in the clamping hole.

[0047] In this embodiment, the clamping member 4 is inserted into the clamping hole to fix the stopper 3. Compared with the welding method, the installation is more convenient, and the problem of leakage welding during welding resulting in holes in the second plate 2 and increased wind resistance is avoided, and the situation of welding points falling off due to vibration, causing the stopper 3 to separate from the second plate 2, is reduced. In addition, there is no need to drill holes in the second plate 2, which not only ensures the strength of the second plate 2, but also avoids the problem of increased wind resistance due to drilling holes.

[0048] In some embodiments, see Figures 2 to 3The clamping member 4 includes a clamping seat 401 and a buckle 402, the clamping seat 401 is connected to the second plate body 2; the buckle 402 includes a connecting piece 4022 and two elastic clamping pieces 4021 arranged on opposite sides of the connecting piece 4022 along a first path, the first path is parallel to the plate surface of the second plate body 2, and an installation gap is formed between the two clamping pieces 4021, the clamping seat 401 is inserted into the installation gap, and the clamping piece 4021 has a clamping protrusion 4021-1 protruding along the first path toward the side away from the connecting piece 4022, and the clamping protrusion 4021-1 passes through the clamping hole and abuts against the limiting member 3.

[0049] The base 401 is inserted into the installation gap to achieve the connection between the buckle 402 and the base 401, and then the buckle 402 is inserted into the clamping hole, and the clamping protrusion 4021-1 passes through the clamping hole and abuts against the limiter 3. This embodiment uses a clamping method to fix the limiter 3, and compared with the screwing method, no nut is required, which avoids the problem of nut loosening due to vehicle vibration.

[0050] Optionally, the holder 401 and the second plate body 2 are integrally formed.

[0051] In some embodiments, see Figures 2 to 3 The socket 401 includes a fixing plate 4011 and two limiting plates 4012, and the fixing plate 4011 is inserted in the installation gap; the two limiting plates 4012 are mirror-symmetrically arranged on both sides of the fixing plate 4011 along the second path, and the second path is perpendicular to the first path. The limiting plate 4012 includes a connecting portion 4012-2 connected to the second plate body 2 and a plug-in portion 4012-1 connected to the connecting portion 4012-2 on the side away from the second plate body 2, and the connecting portion 4012-2 protrudes from the connecting portion 4012-2 along the first path toward the side away from the fixing plate 4011, so that a step is formed at the connection between the connecting portion 4012-2 and the plug-in portion 4012-1, and the step and the clamping protrusion 4021-1 respectively abut against the opposite sides of the limiting member 3.

[0052] The two limiting plates 4012 limit the buckle 402 in the second path to avoid the buckle 402 from being separated from the fixing plate 4011 along the second path due to vibration and other problems. In addition, the design of the limiting plates 4012 can also improve the strength and stability of the fixing plate 4011. After the clamping protrusion 4021-1 passes through the clamping hole, it abuts against the side of the limiting member 3 away from the second plate body 2, and the step abuts against the side of the limiting member 3 close to the second plate body 2, and provides support force to the second plate body 2. The clamping protrusion 4021-1 and the step jointly provide abutment force to the limiting member 3 in the inner and outer directions to ensure the stability of the limiting member 3. In addition, the design of the step avoids the limiting member 3 from directly contacting the second plate body 2, provides space for the vibration and deformation of the limiting member 3, and avoids interference with the second plate body 2.

[0053] In some embodiments, see Figure 1 The hinge assembly includes a fixing member 6, a base 7 and a hinge body 8. The fixing member 6 is arranged on the first plate body 1; the base 7 is arranged on the second plate body 2; and the hinge body 8 is connected to the fixing member 6 and the base 7.

[0054] The base 7 can improve the strength of the second plate 2, and avoid the problem that the second plate 2 is deformed due to the large force on the connection caused by the installation of the hinge body 8. The fixing member 6 is connected to the hinge body 8 and the first plate 1 respectively, which can not only provide a mounting position for the hinge body 8, but also increase the strength of the first plate 1.

[0055] Optionally, the fixing member 6 includes a first fixing plate and a second fixing plate arranged at an angle, the first fixing plate is connected to the hinge body 8, and the second fixing plate is connected to the second plate body 2. The solution in this embodiment can increase the contact area between the fixing member 6 and the hinge body 8 and the second plate body 2, thereby increasing the firmness of the connection.

[0056] In some embodiments, see Figure 4 The hinge assembly further includes a driving member 10 connected to the fixing member 6 and the second plate body 2 respectively, and the driving member 10 controls the second plate body 2 to rotate around the first axis.

[0057] The driving member 10 controls the rotation of the second plate body 2, and there is no need to manually flip the second plate body 2, which reduces the workload and makes the operation more convenient.

[0058] Optionally, the driving member 10 is communicatively connected with an in-vehicle control system, and the driving member 10 controls the second plate 2 to rotate by operating the control system.

[0059] In some embodiments, see Figure 4 The driving member 10 includes a telescopic driver 1001 and a pull rod 1002. The telescopic driver 1001 is rotatably connected to the first plate body 1; one end of the pull rod 1002 is rotatably connected to the telescopic end of the telescopic driver 1001, and the other end is rotatably connected to the second plate body 2.

[0060] When the driver 1001 is extended, the second plate 2 is rotated upward by the pull rod 1002, so that the user can enter and exit the chassis workbench. When the driver 1001 is retracted, the pull rod 1002 is pulled to rotate the second plate 2 downward to reset. This embodiment is simple, and the rotation of the second plate 2 is achieved by extending or retracting the driver 1001.

[0061] Optionally, the pull rod 1002 may include a plurality of tensioning parts connected in series, and adjacent tensioning parts are rotationally connected.

[0062] Optionally, the driver 1001 is a hydraulic telescopic component or a pneumatic telescopic component.

[0064] The connection base 5 mounts the first plate 1 on the vehicle body to fix the first plate 1. The connection protrusion 9 can prevent the connection base 5 from directly contacting the first plate 1, and prevent the connection base 5 from deforming or vibrating due to stress, which may affect the first plate 1.

[0065] Optionally, the connection protrusion 9 is provided with a first connection hole, the connection seat 5 is provided with a second connection hole adapted to the first connection hole, and a locking member is inserted into the first connection hole and the second connection hole. The locking member is a clamping member or a screwing member.

[0066] Based on the same inventive concept, the utility model also provides a deflector assembly, which includes any one of the deflector side plates described above.

[0067] The deflector assembly provided by the utility model adopts the above-mentioned deflector side plate, and the second plate body 2 is connected to the first plate body 1 by rotating around the first axis. When the vehicle is driving normally, the first plate body 1 and the second plate body 2 are located in the same plane. When it is necessary to enter the chassis workbench, the second plate body 2 is rotated around the first axis, and the user can enter the chassis workbench from the clearance space formed by the rotation of the second plate body 2.
