Description

Technical Field

[0001] The utility model relates to the technical field of vehicle engineering, in particular to a vehicle front side air guide plate flipping structure and a vehicle with the vehicle front side air guide plate flipping structure. Background Art

[0002] For commercial vehicles such as trucks, there is a certain space between the front and the cargo box. Airflow easily enters this space when driving, increasing the vehicle's driving resistance. For this reason, guide plates are set on both sides of the front to guide the airflow and prevent it from entering this space.

[0003] The front side deflector in the related technology is set as a flippable structure. When driving, the deflector is flipped to the diversion position to guide the airflow and prevent the airflow from entering the space between the front of the vehicle and the cargo box. When maintenance, charging, etc. are required, the deflector is flipped to the avoidance position to allow personnel to enter the space between the front of the vehicle and the cargo box.

[0004] At the same time, in order to prevent the deflector from shaking randomly when the vehicle is driving, a spring is used to drive the deflector to remain in the flipping limit position. When manually flipping the deflector, the spring force needs to be overcome. On the one hand, the force required to flip the deflector is large, and the flipping operation is difficult. On the other hand, when the deflector flips to the limit position under the action of the spring force, a large instantaneous impact will be generated. Frequent flipping of the deflector is likely to affect the reliability of the relevant connection structure and the vehicle body. Utility Model Content

DETAILED DESCRIPTION

[0026] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0027] The front side deflector in the related technology is set as a flippable structure. When driving, the deflector is flipped to the diversion position to guide the airflow and prevent the airflow from entering the space between the front of the vehicle and the cargo box. When maintenance, charging, etc. are required, the deflector is flipped to the avoidance position to allow personnel to enter the space between the front of the vehicle and the cargo box.

[0028] At the same time, in order to prevent the deflector from shaking randomly when the vehicle is driving, a spring is used to drive the deflector to remain in the flipping limit position. When manually flipping the deflector, the spring force needs to be overcome. On the one hand, the force required to flip the deflector is large, and the flipping operation is difficult. On the other hand, when the deflector flips to the limit position under the action of the spring force, a large instantaneous impact will be generated. Frequent flipping of the deflector is likely to affect the reliability of the relevant connection structure and the vehicle body.

[0029] Specifically, the deflector flipping structure in the related art uses two upper and lower four-bar linkages to connect the mounting seat and the deflector, and connects springs between the connecting rods and the mounting seat to achieve elastic flipping drive of the deflector. Both the upper and lower four-bar linkages are provided with springs.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The following describes the vehicle front side deflector flip structure 1 according to an embodiment of the utility model with reference to the accompanying drawings.

[0034] like Figure 1-Figure 3 As shown, the front side deflector flip structure 1 according to the embodiment of the utility model includes a deflector (not shown in the figure), a plurality of connecting rod mechanisms 10, an elastic member 20 and a damping device 30.

[0035] The deflector is flippably arranged on the front of the vehicle through a plurality of link mechanisms 10, and the plurality of link mechanisms 10 are arranged at intervals in the up-down direction (the up-down direction is indicated by the arrows in the figure). The elastic member 20 is arranged on at least one of the plurality of link mechanisms 10. The damping device 30 is arranged on at least one of the plurality of link mechanisms 10, and the damping device 30 generates damping for the flipping of the deflector.

[0036] Specifically, the deflector can have two extreme flipping positions, namely, a deflector position and an open position. The deflector is located in the deflector position and is suitable for directing the airflow. For example, it can be located between the front of the vehicle and the cargo box and be flush with the side surfaces of the front of the vehicle and the cargo box. The deflector is located in the open position to avoid the space between the front of the vehicle and the cargo box. For example, it can be located on both sides of the front of the vehicle so that the operator can enter the space between the front of the vehicle and the cargo box.

[0037] The elastic member 20 drives the deflector plate to flip so that the deflector plate can be kept in the diverting position or the open position. For example, the flipping of the deflector plate has an intermediate position between the diverting position and the open position. When the deflector plate is between the intermediate position and the diverting position, the elastic member 20 drives the deflector plate to flip to the diverting position. When the deflector plate is between the intermediate position and the open position, the elastic member 20 drives the deflector plate to flip to the open position. Therefore, when the operator flips the deflector plate, he first overcomes the elastic force of the elastic member 20 to flip the deflector plate from one flipping limit position to the intermediate position, and then the deflector plate flips to another flipping limit position under the elastic force of the elastic member 20.

[0038] In the related art, the deflector flipping structure quickly flips to the flipping limit position under the elastic force of the elastic member after the deflector passes the middle position, generating a large instantaneous impact.

[0039] The damping device 30 generates damping for the flipping of the guide plate. During the flipping process of the guide plate, the damping device 30 generates a damping force. On the one hand, it can provide a damping force for the flipping of the guide plate from the flipping limit position to the middle position, so as to facilitate the guide plate to remain in the flipping limit position and avoid the guide plate from shaking randomly. On the other hand, it can provide a damping force for the flipping of the guide plate from the middle position to the flipping limit position, avoid excessive flipping speed and reduce instantaneous impact.

[0040] According to the front side deflector flipping structure 1 of the utility model embodiment, by arranging an elastic member 20 on at least one of the multiple connecting rod mechanisms 10, the elastic member 20 can be used to drive the deflector to flip, so that the deflector can be kept in the flipping limit position and prevent the deflector from shaking randomly during driving.

[0041] Furthermore, by providing a damping device 30 on at least one of the multiple link mechanisms 10, the damping device 30 can be used to provide a damping force for the flipping of the deflector, which can not only facilitate the deflector to remain in the flipping limit position and prevent the deflector from shaking randomly during driving, but also provide damping and buffering when the deflector flips to the flipping limit position under the drive of elastic force, thereby reducing instantaneous impact and avoiding frequent flipping impacts that affect the reliability of related connection structures and vehicle bodies.

[0042] Therefore, compared with the technical solution of only setting elastic members in the related art, the front side deflector flipping structure 1 can, on the one hand, provide damping force for the flipping of the deflector, assist the elastic member 20 to keep the deflector at the flipping limit position, and prevent the deflector from shaking at will, thereby reducing the number of elastic members and reducing the overall elastic force. In this way, the operator needs to overcome the elastic force and damping force when flipping the deflector. Since the elastic force of the elastic member 20 will change due to different flipping degrees, and the damping force of the damping device 30 is relatively more stable, by reducing the number of elastic members 20 to reduce the spring elastic force and increasing the damping force provided by the damping device 30, the operator can apply force more smoothly when flipping the deflector, which is convenient for the flipping operation of the deflector. On the other hand, the damping device 30 can perform damping and buffering when the deflector flips to the flipping limit position under the drive of the elastic force, reducing the instantaneous impact generated when the deflector flips to the flipping limit position, and avoiding frequent flipping impacts that affect the reliability of the relevant connection structure and the vehicle body. Especially for models that set the charging port between the front of the vehicle and the cargo box, due to the need for frequent charging, the deflector needs to be frequently flipped open and closed. Compared with the deflector flipping structure in the related technology, the front side deflector flipping structure 1 can reduce the impact of frequent flipping of the deflector on the relevant connection structure and the reliability of the vehicle body.

[0043] Therefore, the front side deflector flipping structure 1 according to the embodiment of the utility model has the advantages of convenient flipping operation and high reliability.

[0044] The following describes the vehicle front side deflector flip structure 1 according to a specific embodiment of the utility model with reference to the accompanying drawings.

[0045] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the front side deflector flip structure 1 according to the embodiment of the utility model includes a deflector, a plurality of connecting rod mechanisms 10 , an elastic member 20 and a damping device 30 .

[0046] Advantageously, if Figure 1 As shown, the connecting rod mechanism 10 is divided into two parts, namely, an upper connecting rod mechanism and a lower connecting rod mechanism, the elastic member 20 is arranged on the upper connecting rod mechanism and the damping device 30 is arranged on the lower connecting rod mechanism. Specifically, the upper connecting rod mechanism is located above the lower connecting rod mechanism. Compared with the technical solution in the related art in which springs are arranged on both the upper and lower connecting rod mechanisms, since the upper connecting rod mechanism has a greater influence on the overall stability of the deflector than the lower connecting rod mechanism, by retaining the elastic member 20 in the upper connecting rod mechanism and replacing the spring of the lower connecting rod mechanism with the damping device 30, the elastic member 20 and the damping device 30 can be used to ensure the stability of the upper and lower parts of the deflector respectively, thereby more effectively improving the overall stability of the deflector and avoiding the deflector from shaking during driving.

[0047] Specifically, Figure 1-Figure 3As shown, each link mechanism 10 includes a mounting seat 11, a deflector seat 12 and two mutually parallel links 13. The mounting seat 11 is suitable for mounting on the front of the vehicle. The deflector seat 12 is connected to the deflector. Each link 13 is pivotally connected to the mounting seat 11 and the deflector seat 12. In this way, the mounting seat 11, the deflector seat 12 and the two mutually parallel links 13 can form a four-link mechanism, so that the deflector can be turned over under the constraint of the two mutually parallel links 13, which can not only make the deflector have a stable and reliable turning trajectory, but also facilitate the deflector to be stably maintained at the turning limit position, and avoid the deflector from shaking at will.

[0048] Advantageously, if Figure 2 and Figure 3 As shown, the damping device 30 is a rod-type bidirectional damper and its two ends are pivotally connected to the connecting rod 13 and the mounting seat 11, respectively. Specifically, the damping force of the damping device 30 remains stable when the length of the damping device 30 changes. An adapter 31 is provided at one end of the damping device 30, and an axial hole is provided on the adapter 31. The adapter 31 is pivotally connected to the connecting rod 13 through a connecting shaft 32 fitted in the axial hole, and an axial elastic washer 33 is provided between the connecting shaft 32 and the adapter 31. In this way, the damping device 30 can be stretched and compressed by the rotation of the connecting rod 13 when the deflector is flipped, so as to facilitate the provision of bidirectional damping force for the flipping of the deflector, so that the damping device 30 can provide stable and reliable damping force no matter in which direction the deflector is flipped.

[0049] More advantageously, if Figure 2 As shown, the damping device 30 is retracted to the shortest limit position when the deflector is at the two flipping limit positions. Specifically, the length of the damping device 30 reaches the longest when the deflector is at the middle position. In this way, the shortest limit position of the damping device 30 itself can be used to limit the flipping of the deflector, eliminating the need to set an additional limit structure.

[0050] More specifically, the elastic member 20 is a tension spring and is respectively connected to the connecting rod 13 and the mounting seat 11. In this way, the elastic member 20 can be stretched and compressed by the rotation of the connecting rod 13 when the deflector is turned over, so as to provide elastic force for the deflector to turn over to the turning limit position.

[0051] Furthermore, when the deflector is at the two flipping limit positions, the length of the elastic member 20 is shorter than when the deflector is between the two flipping limit positions. Specifically, when the deflector is at the middle position, the length of the elastic member 20 reaches the longest. In this way, the elastic member 20 can be easily kept at the flipping limit position to prevent the deflector from shaking at will.

[0052] Specifically, when the operator flips the deflector from the diversion position to the middle position, it is necessary to overcome the elastic force of the elastic member 20 and the damping force of the damping device 30. After passing the middle position, the deflector flips to the open position under the elastic force of the elastic member 20, and the damping force of the damping device 30 damps and buffers the flipping of the deflector. When the operator flips the deflector from the open position to the middle position, it is necessary to overcome the elastic force of the elastic member 20 and the damping force of the damping device 30. After passing the middle position, the deflector flips to the diversion position under the elastic force of the elastic member 20, and the damping force of the damping device 30 damps and buffers the flipping of the deflector.

[0053] Figure 1 and Figure 2 The figure shows the vehicle front side deflector flipping structure 1 according to some examples of the utility model. Figure 1 and Figure 2 As shown, a first reinforcing link 40 is connected between the two deflector seats 12, and a second reinforcing link 50 is connected between the two connecting rods 13 opposite to each other in the vertical direction. In this way, the first reinforcing link 40 and the second reinforcing link 50 can be used to connect the two connecting rod mechanisms 10, so as to ensure that the two connecting rod mechanisms 10 are turned over synchronously, and the front side deflector turning structure 1 is reinforced to prevent the deflector from being deformed.

[0054] Optionally, the damping force of the damping device 30 is 80-150 N, and the elastic force of the elastic member 20 is 80-120 N. In this way, the flipping force of the deflector can be reduced to a human body comfort zone, which is convenient for operators to flip the deflector, and the impact speed of the deflector when flipping to the extreme position can be reduced by more than 30%, effectively alleviating the impact on the vehicle body and related connection structures, and ensuring the reliability of the flipping structure 1 of the front side deflector.
