[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] Please refer to​Figures 1-7 The application discloses a conveniently-adjustable automobile front air grille, which comprises an assembling frame 1, wherein uniform air inlet openings 11 are arranged on the assembling frame 1, and assembling strips 12 fixed to the assembling frame 1 are arranged between two adjacent groups of the air inlet openings 11.

[0035] The application further comprises an assembling seat 31, a guide sleeve 32, a guide sliding groove 33 and a sliding sleeve 4 which are fixedly combined, and the sliding sleeve 4 is slidingly installed on the periphery of the guide sleeve 32, the assembling seat 31 is fixedly installed on one of the assembling strips 12, the guide sleeve 32 and the guide sliding groove 33 are arranged perpendicularly to the assembling frame 1, and the two sides of the sliding sleeve 4 are hingedly connected with the wind baffles A21 and the wind baffles B22 on the corresponding side through connecting rods C41.

[0036] The application further comprises an active adjusting assembly and a passive adjusting assembly which are in linkage with the sliding sleeve 4, the active adjusting assembly is assembled into the guide sliding groove 33, and the passive adjusting assembly is assembled onto the guide sleeve 32.

[0037] The assembling frame 1 is fixedly installed on the automobile beam or the front bumper through bolt fixation, and is arranged before a front radiator and behind a decorative part of the air grille, when the wind baffles A21 and the wind baffles B22 are in a closed posture, the air inlet openings 11 on the assembling frame 1 can be completely blocked, thereby preventing air from entering the radiator during automobile driving, and the engine working temperature can be quickly increased to a suitable level.

[0038] The connecting rods A23 and the connecting rods B24 can ensure that the turning angles of each group of the wind baffles A21 and the wind baffles B22 are always the same, thereby realizing synchronous control on the opening and closing postures of each air inlet opening 11.

[0039] During normal automobile driving, the specific position of the sliding sleeve 4 on the guide sleeve 32 can be adjusted through the active adjusting assembly or the passive adjusting assembly according to the environmental temperature, the driving speed, the air pressure and the like, and then the opening and closing angles of the wind baffles A21 and the wind baffles B22 are controlled through the connecting rods C41, so as to automatically adjust the opening and closing degree of the air inlet openings 11, and the air flow and the engine cooling efficiency are optimized. For example, the grille can be partially closed to reduce the wind resistance during high-speed driving, and the grille can be completely opened to increase the cooling during low-speed driving or when the engine temperature is relatively high.

[0040] In order to realize the linkage combination of the connecting rods A23 and B24 and the windshields A21 and B22 respectively, and ensure the adjustment of the synchronous opening and closing posture of each group of windshields A21 or B22, the following technical scheme is provided.

[0041] The top of each group of windshields A21 is fixedly connected with a hinge column A25, and the two ends of the connecting rod A23 are hingedly connected with the hinge columns A25 on the adjacent two groups of windshields A21 respectively; the bottom of each group of windshields B22 is fixedly connected with a hinge column B26, and the two ends of the connecting rod B24 are hingedly connected with the hinge columns B26 on the adjacent two groups of windshields B22 respectively.

[0042] When the sliding sleeve 4 slides along the guide sleeve 32, the windshields A21 and B22 directly associated with the connecting rod C41 can be driven to symmetrically flip in opposite directions, and then the synchronous opening and closing of the connecting rods A23 and B24 are realized.

[0043] In order to ensure that the active adjustment assembly can be stably assembled and effectively control the sliding posture of the sliding sleeve 4, the following technical scheme is provided.

[0044] The active adjustment assembly comprises a driving motor A51, an adjusting screw 52 and a sliding seat 53. The sliding seat 53 is slidingly installed in the guide sliding groove 33, the adjusting screw 52 is rotationally installed in the guide sliding groove 33 and is rotationally connected with the sliding seat 53, and the driving motor A51 is fixedly installed in the assembly seat 31 and is power-connected with the adjusting screw 52.

[0045] The sliding sleeve 4 is fixedly connected with a clamping head 42, and the sliding seat 53 is fixedly connected with two groups of symmetrically arranged clamping grooves 531, which are nested and matched with the clamping head 42.

[0046] The distance between the two groups of clamping grooves 531 is smaller than the stroke range of the clamping head 42, so that when the passive adjustment assembly acts on the sliding sleeve 4, the running posture of the sliding sleeve 4 can be avoided from being interfered by the clamping grooves 531.

[0047] When the windshields A21 and B22 are controlled to be in a completely closed posture, the driving motor A51 drives the adjusting screw 52 to rotate, and then drives the sliding seat 53 and the clamping grooves 531 thereon to stably slide in the guide sliding groove 33, so that the clamping grooves 531 away from the assembly frame 1 are nested and combined with the clamping head 42, and the clamping head 42 and the sliding sleeve 4 are driven to run to the stroke end close to the assembly frame 1, at this time, the two ends of the sliding sleeve 4 are in a locked state under the limiting action of the assembly seat 31 and the clamping grooves 531, and the windshields A21 and B22 are in a completely closed state.

[0048] When the control of the wind shield A21, the wind shield B22 is in a fully open or not less than a certain opening angle posture, the drive motor A51 drives the adjusting screw 52 to rotate, so that the clamping groove 531 on the side close to the assembly frame 1 is nested with the clamping head 42, and the sliding sleeve 4 is pushed to move away from the side of the assembly frame 1, so that the wind shield A21, the wind shield B22 is turned inward to present an open posture.

[0049] In order to ensure that the passive adjustment assembly can be stably assembled, and the opening and closing posture of the passive adjustment assembly can be adjusted according to the wind speed flowing into the air inlet grille during driving of the automobile, the following technical solutions are provided.

[0050] The passive adjustment assembly comprises a connecting shaft 61, an adjusting ring seat 62 and a supporting spring 63. The connecting shaft 61 and the adjusting ring seat 62 are fixedly connected and are respectively slidably installed on the inner and outer sides of the guide sleeve 32. The supporting spring 63 is sleeved on the periphery of the guide sleeve 32, and the two ends of the supporting spring 63 respectively abut against the sliding sleeve 4 and the adjusting ring seat 62.

[0051] An assembly through groove 321 is formed in the side wall of the guide sleeve 32, and the assembly through groove 321 extends to the end of the guide sleeve away from the assembly seat 31. A limiting cover 322 is screwed on the end. The connecting shaft 61 and the adjusting ring seat 62, which are processed as a unified whole, can be assembled on the guide sleeve 32 from the assembly through groove 321 of the end. Then, the limiting cover 322 is screwed to prevent the connecting shaft 61 and the adjusting ring seat 62 from falling off the end.

[0052] The connecting shaft 61 and the adjusting ring seat 62 can slide axially in the assembly through groove 321, and adjust the distance between the adjusting ring seat 62 and the sliding sleeve 4, thereby effectively regulating the tension of the supporting spring 63. During driving of the automobile, when the airflow enters the air inlet grille and hits the wind shield A21 and the wind shield B22, an acting force is applied to the wind shield A21 and the wind shield B22, and the elastic force provided by the supporting spring 63 acts on the sliding sleeve 4. When the air flow rate reaches a certain threshold value, the acting force is greater than the elastic force provided by the supporting spring 63, which can push the sliding sleeve 4 to move backward, thereby making the wind shield A21 and the wind shield B22 turn inward to an open posture. When the airflow acting force and the elastic force of the supporting spring 63 reach a balance state, the opening and closing posture of the wind shield A21 and the wind shield B22 presents a certain angle to accurately regulate the air inlet amount.

[0053] In order to accurately adjust the position and posture of the adjusting ring seat 62, and effectively adjust the elastic force of the supporting spring 63 applied to the sliding sleeve 4, the following technical solutions are provided.

[0054] The passive adjusting assembly further comprises a driving motor B64, a driving gear 65, and a matched worm 66 and worm gear 67, the worm gear 67 is coaxially fixedly connected with the driving gear 65 and is rotatably installed on the assembling seat 31, the connecting shaft 61 is arranged in the assembling seat 31, and the connecting shaft 61 is provided with a transmission rack 68 which is in engagement with the driving gear 65, the driving motor B64 is fixedly installed on the assembling seat 31, and the output shaft of the driving motor B64 is coaxially fixedly connected with the worm 66.

[0055] When the driving motor B64 works, the driving gear 65 can be stably driven to rotate through the combination of the worm 66 and the worm gear 67, and then the driving gear 65 drives the transmission rack 68, the connecting shaft 61 and the adjusting ring seat 62 to stably slide in the guide sleeve 32, so as to adjust the distance between the adjusting ring seat 62 and the sliding sleeve 4.

[0056] Since the combination of the worm 66 and the worm gear 67 has the characteristics of speed reduction and torque increase, the resistance provided by the supporting spring 63 can be effectively overcome, and the position of the adjusting ring seat 62 can be adjusted, and the combination of the worm 66 and the worm gear 67 also has the characteristics of one-way self-locking, that is, power can only be transmitted from the worm 66 to the worm gear 67, after the position adjustment of the adjusting ring seat 62 is completed and the driving motor B64 is stopped, the worm 66 can lock and position the worm gear 67 and the driving gear 65, so as to limit the invalid movement of the transmission rack 68, the connecting shaft 61 and the adjusting ring seat 62, and ensure that the supporting spring 63 can provide stable resistance.

[0057] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
