[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.

[0050] In addition, the front and rear direction of the vehicle body defined in the embodiments of the present invention refers to the front and rear direction of the forward direction of the vehicle during driving, the left and right direction of the vehicle body defined refers to the left and right direction of the forward direction of the vehicle during driving, and the up and down direction of the vehicle body defined refers to the up and down direction of the forward direction of the vehicle during driving.

[0051] Please also read Figure 1 and Figure 2, the linear push-pull structure provided by the utility model is now described. The linear push-pull structure includes a damping gear 1, a sliding block 2 and an elastic stopper 3. The sliding block 2 has a rack 21, and the rack 21 is meshed with the damping gear 1; the sliding block 2 also has at least two positioning parts 22, and the at least two positioning parts 22 are spaced apart along the sliding direction of the sliding block 2; the elastic stopper 3 is located on the outside of the sliding block 2; the elastic stopper 3 has an elastic degree of freedom to move away from / close to the sliding block 2. Among them, when the sliding block 2 moves, the elastic stopper 3 can be elastically engaged with any positioning part 22 to limit the moving position of the sliding block 2.

[0052] The sliding block 2 can slide along a preset straight path, and the sliding block 2 is pushed and pulled directly by humans or indirectly pushed and pulled by force members such as pull rods. During the sliding process, the rack 21 meshes with the damping gear 1, and the damping gear 1 provides sliding resistance to enhance the manual push and pull operation feeling.

[0053] Relative to the sliding of the sliding block 2, the damping gear 1 and the elastic stop 3 are both in a non-sliding state, that is, the damping gear 1 and the elastic stop 3 are respectively fixed to a certain component or fixed to the same component together, the damping gear 1 can rotate around its central axis, and the elastic stop 3 can elastically extend and elastically retract in the direction away from / approaching the sliding block 2. Preferably, the direction of the above-mentioned elastic extension and elastic retraction is perpendicular to the sliding direction.

[0054] When the sliding block 2 slides to any one of the positioning portions 22 and elastically engages with the elastic stopper 3 under manual pushing and pulling, the elastic stopper 3 and the positioning portion 22 form a limit in the direction of elastic extension and elastic retraction. Due to the engaging action, the operator is prompted to move the sliding block 2 to a specified position; when force is applied to the sliding block 2 again, the elastic engaging of the elastic stopper 3 and the positioning portion 22 will be destroyed, so that the sliding block 2 continues to slide until the next positioning portion 22 is elastically engaged with the elastic stopper 3.

[0055] Preferably, the elastic snap connection preferably adopts the cooperation mode of a card block and a card slot, for example, a card block is provided on the elastic stopper 3 and a card slot is provided on the positioning part 22, or a card slot is provided on the elastic stopper 3 and a card block is provided on the positioning part 22.

[0056] The linear push-pull structure provided by the embodiment of the utility model can be used to connect with certain components of the vehicle, and the components can be driven to complete the fixing action through the linear operation of the linear push-pull structure. For example, it can be applied to the vehicle armrest box cover to make the armrest box cover move linearly; it can also be applied to the air volume regulating valve of the air outlet of the air conditioner, and cooperate with the intermediate transmission structure to make the valve rotate.

[0057] Compared with the prior art, the linear push-pull structure provided by the utility model is characterized in that the rack 21 of the sliding block 2 is meshed with the damping gear 1, and the damping gear 1 provides a sliding damping force; at least two positioning portions 22 are arranged on the sliding block 2, and when the sliding block 2 moves to abut against the elastic stopper 3, the elastic stopper 3 can be engaged with the positioning portion 22 to form a limit in the sliding direction, thereby positioning the moving position of the sliding block 2 to ensure that the moving position of the component connected to the sliding block 2 is accurate.

[0058] In some embodiments, the linear push-pull structure can also be used as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The linear push-pull structure further comprises a mounting base 4 . The damping gear 1 and the elastic stopper 3 are both arranged on the mounting base 4 .

[0059] The mounting base 4 is used to provide a support carrier for fixing the damping gear 1 and the elastic stopper 3. The damping gear 1 and the elastic stopper 3 are arranged together on the mounting base 4, which can simplify the overall structure of the linear push-pull structure and facilitate assembly.

[0060] In some embodiments, the mounting base 4 may be Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The mounting base 4 has a sliding cavity 41 ; the damping gear 1 and the sliding block 2 are both located in the sliding cavity 41 .

[0061] Specifically, the surface of the mounting base 4 is also provided with a mounting opening matching the shape of the damping gear 1, and the damping gear 1 is assembled to the mounting opening and extends into the sliding cavity 41. The sliding block 2 is placed in the sliding cavity 41 and slides along a preset straight line direction.

[0062] The mounting base 4 wraps the damping gear 1 to shield the damping gear 1 and prevent the meshing portion between the damping gear 1 and the rack 21 from being exposed, thereby improving the stability and reliability of the meshing.

[0063] See also Figure 1 and Figure 2 On the basis of the above embodiment, the mounting base 4 is provided with a slide groove 42, and the slide block 2 is provided with a guide block 23; the guide block 23 is slidably arranged in the slide groove 42. In addition, the length of the slide groove 42 is equal to the spacing distance between the two positioning parts 22 located at the side.

[0064] The slide groove 42 is in the shape of a long strip, and its extension direction is the preset straight path direction of the sliding block 2. The groove width of the slide groove 42 is adapted to the width of the guide block 23, and the guide block 23 and the slide groove 42 are slidably matched to guide the sliding block 2 to slide along the preset path, ensuring that the rack 21 and the damping gear 1 are normally meshed.

[0065] The length of the slide groove 42 also limits the moving distance of the sliding block 2 . In other words, the length of the slide groove 42 is the maximum moving distance of the sliding block 2 . Among the multiple positioning parts 22, two positioning parts 22 located on the sides are defined as the first positioning part and the second positioning part respectively. Since the length of the slide groove 42 is equal to the spacing distance between the first positioning part and the second positioning part, when the sliding block 2 slides to the first positioning part, the elastic stopper 3 elastically abuts against the first positioning part, and the guide block 23 abuts against one of the groove side walls (the groove side wall in the length direction) of the slide groove 42. When the sliding block 2 slides to the second positioning part, the elastic stopper 3 elastically abuts against the second positioning part, and the guide block 23 abuts against the other groove side wall (the groove side wall in the length direction) of the slide groove 42. The elastic stopper 3 is elastically clamped with the positioning part 22, and the guide block 23 abuts against the groove side wall of the slide groove 42. Through double limiting, it is ensured that the state of the sliding block 2 is stable when it moves to the extreme position, and it is avoided that the rack 21 and the damping gear 1 are separated due to excessive external force.

[0066] Since the guide block 23 is located in the slide groove 42 and the sliding block 2 is located in the sliding cavity 41, when assembling the sliding block 2 and the mounting base 4, in order to facilitate the guide block 23 to extend into the slide groove 42, the guide block 23 is designed as a triangular block, one side of which is an inclined surface. Due to the inclination of the inclined surface, it is convenient to slide the guide block 23 into the slide groove 42 during assembly.

[0067] In addition to guiding the sliding block 2 to slide linearly, the guide block 23 also has the function of abutting against the groove wall of the slide groove 42 at the limit position to further limit the sliding block 2. Since one side of the guide block 23 is an inclined surface, there will be a problem of unstable abutment due to the small abutment area at one of the limit positions. In order to avoid the above problem, please refer to Figure 1 and Figure 2 On the basis of the above embodiment, a stop block 24 is provided on the sliding block 2, and the mounting base 4 has a stop surface 43; when the elastic stop member 3 is elastically engaged with one of the positioning portions 22 located on the side, the guide block 23 abuts against the side wall of the slide groove 42 in the length direction; when the elastic stop member 3 is elastically engaged with the other positioning portion 22 located on the side, the stop block 24 abuts against the stop surface 43.

[0068] Specifically, the sliding block 2 partially extends out of the sliding cavity 41 , the stop block 24 is located outside the sliding cavity 41 , and the stop surface 43 is a portion of the outer surface of the mounting base 4 .

[0069] by Figure 1 For reference, if the direction of the inclined surface of the guide block 23 is defined as the positive direction of the sliding direction, the side positioning portion 22 located in the positive direction of the sliding direction is the first positioning portion, and the side positioning portion 22 located in the negative direction of the sliding direction is the second positioning portion. When the elastic stopper 3 is elastically engaged with the first positioning portion, the negative plane of the guide block 23 abuts against the negative groove side wall of the slide groove 42. At this time, the slide block 2 is in the first extreme position, as shown in FIG. Figure 1 As shown, the stop block 24 is disengaged from the stop surface 43. When the elastic stopper 3 is elastically engaged with the second positioning portion, a small portion of the inclined surface of the guide block 23 abuts against the positive groove side wall of the slide groove 42, and the stop block 24 abuts against the stop surface 43, and the sliding block 2 is at the second limit position.

[0070] By adding the stop block 24 and the stop surface 43, the problem of unstable contact caused by the small contact area between the inclined surface of the guide block 23 and the side wall of the slide groove 42 can be avoided, thereby increasing the stability of the sliding block 2 in the second limit position.

[0071] In some embodiments, the positioning portion 22 and the elastic stopper 3 can be used as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The positioning portion 22 is a positioning groove arranged on the outer wall of the sliding block 2; the elastic protruding end of the elastic stopper 3 is clamped and limited in the positioning groove.

[0072] When the elastic stopper 3 is elastically engaged with the positioning groove, the elastic stopper 3 elastically extends out. When the elastic stopper 3 is separated from the positioning groove, the elastic stopper 3 is squeezed by the outer surface of the sliding block 2 and elastically retracted.

[0073] The positioning portion 22 is designed as a positioning groove, which makes its structure simple and easy to manufacture. In addition, after the elastic stopper 3 is separated from the positioning groove, the elastic stopper 3 elastically retracts to store energy, so that it can store a large elastic potential energy, so that after the sliding block 2 moves to the positioning groove and connects with the elastic stopper 3, the elastic stopper 3 can be quickly extended and elastically abutted against the positioning groove.

[0074] See also Figure 3 On the basis of the above embodiment, the elastic stopper 3 includes a base 31, a contact block 32 and an elastic body 33. The base 31 has a receiving cavity 311; the contact block 32 is partially located in the receiving cavity 311; one end of the contact block 32 is an elastic extension end, and the outer surface of the elastic extension end is an outer convex curved surface; the contact block 32 has a limiting cavity; the elastic body 33 is partially located in the limiting cavity, one end of which is in contact with the cavity bottom wall of the limiting cavity, and partially located in the receiving cavity 311, and the other end of which is in contact with the cavity bottom wall of the receiving cavity 311.

[0075] Preferably, the groove wall of the positioning groove is a concave surface, and the elastic extension end of the elastic stopper 3 is a convex surface. The design of the concave and convex surfaces can ensure that the positioning groove moves smoothly to abut or separate from the extension end of the elastic stopper 3.

[0076] The base 31 itself is fixed on the mounting base 4, and the base 31 serves to place the elastic body 33 and the abutment block 32. The elastic body 33 is partially located in the limiting cavity and partially located in the accommodating cavity 311, so that the elastic body 33 is completely wrapped and can be radially limited by the limiting cavity to ensure that the elastic body 33 can only be elastically extended or elastically retracted along its axial direction, thereby increasing the stability of the elastic stopper 3 during elastic movement.

[0077] See also Figure 4 and Figure 5 Based on the same inventive concept, the embodiment of the present application also provides an air outlet structure for an air conditioner, comprising an air outlet housing 5, an air valve 6, a connecting rod assembly 7, the above-mentioned linear push-pull structure, and a pull rod 8. The air valve 6 is rotatably arranged inside the air outlet housing 5; the connecting rod assembly 7 is located outside the air outlet housing 5, and one end is connected to the rotating shaft of the air valve 6; the damping gear 1 and the elastic stopper 3 of the linear push-pull structure are both fixed on the air outlet housing 5, and the sliding block 2 is connected to the other end of the connecting rod assembly 7; the pull rod 8 is connected to the sliding block 2; and the pull rod 8 extends to the downstream of the air outlet of the air outlet housing 5.

[0078] The air outlet housing 5 is installed on the vehicle body at a location where air outlet is required, such as the auxiliary instrument panel 9, the armrest box, etc. The inner cavity of the air outlet housing 5 can be regarded as an air duct, and the air output by the air conditioner enters the vehicle through the air outlet housing 5. The damping gear 1 and the elastic stopper 3 of the linear push-pull structure are both fixed on the air outlet housing 5, and the above-mentioned mounting base 4 can be regarded as a part of the air outlet housing 5.

[0079] The air valve 6 is rotatably arranged inside the air outlet housing 5, that is, rotatably arranged inside the air duct. By rotating the air valve 6, the swing angle of the air valve 6 relative to the air duct can be adjusted. If the plane of the air duct that is perpendicular to the air outlet wind direction is defined as the reference plane, the air valve 6 can be swung to be parallel to the reference plane, and can also be swung to form any angle with the reference plane. When the air valve 6 is parallel to the reference plane, the air valve 6 completely blocks the air duct, and the air conditioning output air cannot be output into the vehicle. When there is an angle between the air valve 6 and the reference plane, the air conditioning output air can be output into the vehicle through the air outlet space between the air valve 6 and the air outlet housing 5. By adjusting the swing angle of the air valve 6, the output air volume can be adjusted.

[0080] The air valve 6 is driven by the connecting rod assembly 7, the linear push-pull structure and the pull rod 8. Specifically, one end of the pull rod 8 is connected to the sliding block 2, and the other end extends to the downstream of the air outlet housing 5 and passes through the vehicle body. The pull rod 8 is manually pushed and pulled. The sliding block 2 is pushed and pulled manually to drive the connecting rod assembly 7 to swing, and the connecting rod assembly 7 drives the air valve 6 to rotate. Preferably, the output shaft of the air valve 6 is connected to a rotating disk 61, one end of the connecting rod assembly 7 is hinged to the rotating disk 61, and the other end is hinged to the sliding block 2.

[0081] In the process of manually pushing and pulling the pull rod 8, the rack 21 meshes with the damping gear 1, and the damping gear 1 provides sliding resistance to enhance the manual push-pull operation feeling. In addition, when the sliding block 2 slides to any one of the positioning parts 22 and elastically engages with the elastic stopper 3 during manual pushing and pulling, the elastic stopper 3 and the positioning part 22 form a limit in the direction of elastic extension and elastic retraction. Due to the existence of the engaging action, the operator will be prompted to move the sliding block 2 to a certain specified position; when force is applied to the sliding block 2 again, the elastic engagement between the elastic stopper 3 and the positioning part 22 will be destroyed, so that the sliding block 2 continues to slide until the next positioning part 22 is elastically engaged with the elastic stopper 3.

[0082] It should be noted that the sliding block 2 has two extreme positions: Figure 1 , Figure 4 and Figure 5 For reference, if the direction of the inclined surface of the guide block 23 is defined as the positive direction of the sliding direction, the side positioning portion 22 located in the positive direction of the sliding direction is the first positioning portion, and the side positioning portion 22 located in the negative direction of the sliding direction is the second positioning portion. When the elastic stopper 3 is elastically engaged with the first positioning portion, the sliding block 2 is in the first limit position, such as Figure 1 , Figure 4 and Figure 5 As shown, in the first limit position, the air valve 6 swings to be perpendicular to the reference plane, at which time the opening angle of the air valve 6 is the largest and the air volume output is the largest. When the elastic stopper 3 is elastically engaged with the second positioning portion, the sliding block 2 is in the second limit position. In the second limit position, the air valve 6 swings to be parallel to the reference plane, the air valve 6 blocks the air duct, and no air volume is output.

[0083] Compared with the prior art, the air outlet structure of the air conditioner provided in the embodiment of the utility model can drive the air valve 6 to rotate through the pull rod 8, the sliding block 2 and the connecting rod assembly 7 to adjust the output air volume; since the sliding block 2 is provided with at least two positioning parts 22, when the sliding block 2 moves to one of the positioning parts 22 and abuts against the elastic stopper 3, the elastic stopper 3 can be engaged with the positioning part 22 to form a limit in the sliding direction, and locate the moving position of the sliding block 2 to ensure the accurate rotation position of the air valve 6 and ensure the stability of the air valve 6.

[0084] In some embodiments, the pull rod 8 may be Figure 1 , Figure 2 and Figure 4 The structure shown, see Figure 1 , Figure 2 and Figure 4 A fixing sleeve 51 is provided on the outer wall of the air outlet housing 5 , the pull rod 8 passes through the fixing sleeve 51 , and a limiting rubber sleeve 81 is embedded between the pull rod 8 and the fixing sleeve 51 .

[0085] The fixing sleeve 51 is used to guide the pull rod 8 to push and pull, so as to prevent the pull rod 8 from deflecting and shaking without external force. The limiting rubber sleeve 81 is sleeved between the pull rod 8 and the fixing sleeve 51. On the one hand, the limiting rubber sleeve 81 can provide damping force to improve the manual push and pull operation feeling, and on the other hand, it can also form a radial limit to ensure that the pull rod 8 can only be pushed and pulled along the axial direction.

[0086] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the above-mentioned air-conditioning outlet structure.

[0087] The vehicle provided by the utility model adopts the above-mentioned air outlet structure of the air conditioner, and the rotation angle of the air valve 6 can be manually controlled to adjust the output air volume, and the rotation position of the air valve 6 can also be accurately located to improve the stability of the air valve 6.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
