Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a handle and a vehicle. Background Art

[0002] The air supply inside an automobile carriage is usually realized by an air supply device with a blowing function, such as, but not limited to, a grille or an air outlet, etc., to provide a comfortable riding environment for passengers. The air supply device needs to occupy a certain amount of space inside the vehicle and affect the movable space of passengers. If an air supply device is added inside the carriage, the movable space of passengers will be reduced and the comfort will be lowered.

[0003] In view of this, there is an urgent need to provide a solution for the existing in-vehicle air supply to overcome the above-mentioned defects. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a handle and a vehicle. Through the structural optimization of the handle, on the basis of ensuring the comfort of passengers, the space occupied by the in-vehicle air supply structure is reduced, providing good technical support for improving the comfort of passengers.

[0005] The first aspect of the utility model provides a handle, which includes a first handle seat, a second handle seat and a rotating handle tube; the first handle seat and the second handle seat are respectively used for being assembled and fixed with a fixed member, and a rotating handle tube is rotatably arranged between the first handle seat and the second handle seat, and external ventilation holes penetrating the wall body are formed on the rotating handle tube; the first handle seat is a hollow structure with openings at both ends, one end of which is communicated with the rotating handle tube to form a hollow cavity, and the other end is used for being communicated with an air duct; a blocking part for blocking the hollow cavity is arranged on the second handle seat, or a blocking part for blocking the hollow cavity is arranged at the connecting end of the rotating handle tube and the second handle seat. With such a setting, air flow can be sent into the hollow cavity of the handle through the first handle seat and blown into the carriage through the external ventilation holes on the rotating handle tube. On the basis of providing a holding function, the blowing function can be concurrently realized to meet the comfort requirements of passengers. In addition, integrating the blowing function on the handle can also reduce the space occupied inside the vehicle. Moreover, rotating the rotating handle tube can adjust the position of the external ventilation holes to adjust the blowing direction according to the needs of passengers and blow to different parts of the human body, which can further improve the comfort.

[0006] Based on the first aspect, the utility model also provides a first implementation manner of the first aspect: the first handle seat and the second handle seat are connected by a hollow inner tube, the first handle seat is communicated with the hollow inner tube, and internal ventilation holes penetrating the wall body are formed on the hollow inner tube; the rotating handle tube is sleeved outside the hollow inner tube, and the external ventilation holes can be communicated with the internal ventilation holes. With such a setting, based on the rotatably arranged rotating handle tube, corresponding air supply channels can be formed by adapting the internal and external ventilation holes, which can further improve the adaptability of the adjustment operation.

[0007] Exemplarily, the shape and size of the outer ventilation hole and the inner ventilation hole can be the same.

[0008] In other examples, the second handle seat has a hollow structure with one end open and the other end closed. One end of it is communicated with the hollow inner tube, and the blocking portion is arranged at the other end of the second handle seat.

[0009] Based on the first implementation manner of the first aspect, the present invention also provides a second implementation manner of the first aspect: A rotational limit pair is arranged between the rotary handle tube and the hollow inner tube, and is configured to limit the rotational stroke of the rotary handle tube relative to the hollow inner tube, so that the rotary handle tube rotates and switches between a first working position and a second working position. In this way, it is convenient for the user to sense and judge when rotating the rotary handle tube, and has good operability.

[0010] Based on the second implementation manner of the first aspect, the present invention also provides a third implementation manner of the first aspect: Among the rotary handle tube and the hollow inner tube, a limiting convex portion is arranged on one of them, and a limiting groove is formed on the other. The limiting convex portion is placed in the limiting groove to form a rotational limit pair; in the rotational direction of the rotary handle tube, the two side walls of the limiting groove are respectively a first limiting surface and a second limiting surface; when the first limiting surface abuts against one side of the limiting convex portion, the rotary handle tube is in the first working position; when the second limiting surface abuts against the other side of the limiting convex portion, the rotary handle tube is in the second working position. It has the characteristics of simple and reliable structure.

[0011] Optionally, when the rotary handle tube is between the first working position and the second working position, the flow-through area of the outer ventilation hole can be located within the flow-through area of the inner ventilation hole. In this state, the air supply airway has the maximum air flow rate; when the rotary handle tube is in the first working position and the second working position, the outer ventilation hole can be staggered from the inner ventilation hole. In this state, the air supply airway is in a closed state and no air flow is blown out.

[0012] In other options, when the rotary handle tube is in the first working position, the flow-through area of the outer ventilation hole can be located within the flow-through area of the inner ventilation hole; when the rotary handle tube is in the second working position, the outer ventilation hole can be staggered from the inner ventilation hole. That is to say, the rotational stroke of the rotary handle tube is from the first working position with the maximum air flow rate, gradually decreasing to the second working position of closing the airway.

[0013] Based on the first implementation manner of the first aspect, or the second implementation manner of the first aspect, or the third implementation manner of the first aspect, the present invention also provides a fourth implementation manner of the first aspect: The outer ventilation holes and the inner ventilation holes are respectively arranged in multiple numbers and are arranged in one-to-one correspondence. In this way, a uniform blowing effect can be formed.

[0014] In other practical applications, the inner ventilation holes can also be arranged as a hole structure communicating with a plurality of outer ventilation holes, so as to reduce the wind resistance on the air supply path and reasonably control the efficiency of the air conditioning system.

[0015] Based on the first implementation manner of the first aspect, or the second implementation manner of the first aspect, or the third implementation manner of the first aspect, the present utility model further provides a fifth implementation manner of the first aspect: the size of the outer ventilation hole in the circumferential direction is smaller than the size of the inner ventilation hole in the circumferential direction. With such a setting, within the rotation stroke of the rotary handle tube, there can be a sub-stroke for maintaining the maximum air volume when adjusting the blowing direction; that is to say, when the rotary handle tube rotates within the sub-stroke, the through-flow area of the outer ventilation holes thereon all remains in communication with the inner ventilation holes and is not blocked by the wall of the hollow inner tube; when the rotary handle tube continues to rotate beyond the sub-stroke, the wall of the hollow inner tube will gradually block the outer ventilation holes, and the air volume will gradually decrease until it is completely blocked and in a closed state.

[0016] Based on the first implementation manner of the first aspect, or the second implementation manner of the first aspect, or the third implementation manner of the first aspect, the present utility model further provides a sixth implementation manner of the first aspect: sealing rings are respectively arranged between the two end portions of the rotary handle tube and the hollow inner tube. The sealing rings can be deformed under pressure after assembly to form a reliable sealing relationship between the rotary handle tube and the hollow inner tube. In this way, the air flow sent into the cavity of the handle can only be blown into the vehicle compartment through the air supply channel far away formed by the inner ventilation holes and the outer ventilation holes, so as to obtain a better blowing effect under the same system air supply parameters. In addition, based on the setting of the sealing rings, during the process of rotating the rotary handle tube, the sealing rings deformed under pressure can also synchronously provide a certain frictional resistance, and the rotation feel is better; in addition, the setting of the sealing rings can also support the rotary handle tube to remain in a determined adjustment position and avoid the rotary handle tube deviating from the determined position adjusted by the occupant due to vibration during vehicle driving.

[0017] Based on the first aspect, the present utility model further provides a seventh implementation manner of the first aspect: the two ends of the rotary handle tube are inserted and adapted between the first handle seat and the second handle seat. The structure is simple and reliable, and the process implementation cost can be reasonably controlled.

[0018] Based on the first aspect, or the first implementation manner of the first aspect, or the seventh implementation manner of the first aspect, the present utility model further provides an eighth implementation manner of the first aspect: the two end portions on the outer peripheral surface of the rotary handle tube are respectively flush with the connection end of the opposite first handle seat and the connection end of the second handle seat. In this way, the overall appearance has a smooth transition, and at the same time, it can avoid affecting the user's feel during the process of rotating the rotary handle tube.

[0019] A second aspect of the present utility model provides a vehicle, which includes a vehicle body and an interior trim panel located inside the vehicle body, and further includes an air duct and the aforesaid handle. The handle is fixedly arranged on the interior trim panel or the vehicle body, and the air duct communicates with the first handle seat of the handle. Based on the configuration of this handle, air flow can be sent into the hollow cavity of the handle through the first handle seat, and blown into the carriage through the external ventilation holes on the rotating handle tube. On the basis of providing a gripping function, it can also realize a blowing function to meet the comfort requirements of the occupants. In addition, integrating the blowing function on the handle can reduce the occupation of the vehicle interior space at the same time; and the blowing direction can be adjusted according to the needs of the occupants, further improving the comfort.

[0020] Exemplarily, the handle can be arranged at positions such as the vehicle door, the vehicle roof or the center console.

[0021] In practical applications, a seal is arranged between the air duct and the first handle seat to ensure that all the air flow on the air duct side is sent into the hollow cavity on the handle side. Description of the Drawings

Detailed implementation manners

[0039] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the prior art, the air supply in the automobile compartment is usually realized by means of a grille or an air outlet. Such an air supply device with a blowing function occupies the interior space of the vehicle and to a certain extent affects the movable space of the occupants. In order to improve the air supply capacity and increase the number of air supply devices, the movable space of the occupants will be reduced, and the comfort of the occupants will be lowered. For passenger vehicles, with the increasing trend of comfort performance requirements, the above problems are more prominent.

[0041] Based on this, an embodiment of the present application provides a handle integrated with a blowing function. The handle includes a first handle base, a second handle base, and a rotating handle tube. The first handle base and the second handle base are respectively used for assembling and fixing with fixed components, and the rotating handle tube is rotatably arranged between the first handle base and the second handle base. The rotating handle tube is provided with external ventilation holes penetrating through the wall body; the first handle base is a hollow structure with openings at both ends, and one end of the first handle base is communicated with the rotating handle tube to form a hollow cavity, and the other end is used for communicating with an air duct; a blocking portion for blocking the hollow cavity is arranged on the second handle base or at the connection end of the rotating handle tube and the second handle base.

[0042] With such a setting, air flow can be sent into the hollow cavity of the handle through the first handle base and blown into the carriage through the external ventilation holes on the rotating handle tube. On the basis of providing a holding function, the blowing function can be achieved at the same time to meet the comfort requirements of passengers. In addition, integrating the blowing function on the handle can reduce the occupation of the interior space of the vehicle at the same time. In addition, rotating the rotating handle tube can adjust the position of the external ventilation holes to adjust the blowing direction according to the needs of passengers and blow to different parts of the human body, which can further improve the comfort.

[0043] To better understand the technical solutions and technical effects of the present application, without loss of generality, the following will describe specific embodiments in detail with reference to the accompanying drawings. Please refer to Figure 1 and Figure 2 , where Figure 1 is a schematic diagram of the assembly relationship of a handle provided by an embodiment of the present application, Figure 2 is Figure 1 another perspective assembly relationship diagram of the handle shown in

[0044] As shown in Figure 1 , the handle 10 is fixedly arranged and can be used for passengers to hold. In a specific implementation, the handle 10 can be fixedly arranged on the interior trim panel 20 as shown in the figure. Of course, in other possible implementation schemes, it can also pass through the interior trim panel 20 and be fixed to the vehicle body 40 (not shown in the figure); in other words, in addition to the interior trim panel 20, the vehicle body 40 can be used as the fixed component of the handle, and specific selection can be made according to the overall design requirements, which is not limited in the embodiments of the present application.

[0045] In this implementation scheme, the handle 10 is fixed through two end parts respectively. One of the fixed end parts can be communicated with the air duct 30 so that air flow can enter the hollow cavity of the handle 10 and be blown out through the air supply channel P opened on the handle 10. Please refer to Figure 3 and Figure 4 , where Figure 3 is Figure 1 the front view of the handle shown in Figure 4 is Figure 3 the A-A cross-sectional view in

[0046] As shown in the figure, the handle 10 includes a first handle base 1, a second handle base 2, a hollow inner tube 3, and a rotating handle tube 4. Please also refer to Figure 5 , which is the Figure 1 exploded assembly diagram of the handle shown in

[0047] Among them, both the first handle base 1 and the second handle base 2 are hollow structures, and they are connected by the hollow inner tube 3, and the three are connected to form a hollow cavity of the handle 10.

[0048] In a specific implementation, the first handle base 1 and the second handle base 2 are bent towards the same side, respectively forming two ends for fixing. In this way, an insertable space is formed between the interior trim panel 20 and the handle 10 to realize the grasping function of the handle. The first handle base 1 and the second handle base 2 shown in the figure are both bent in an arc shape. In other specific implementations, the first handle base 1 and the second handle base 2 can also be bent in a shape with an included angle, which is not limited in the embodiments of the present application.

[0049] In this implementation scheme, the first fixed end 11 of the first handle base 1 is an open fixed end with an opening, and the first fixed end 11 is communicated with the air duct 30; that is to say, the first handle base 1 is a hollow structure with openings at both ends, so as to send air into the hollow cavity of the handle 10 through the air duct 30. The second fixed end 21 of the second handle base 2 is a closed fixed end with a blocking portion 22; that is to say, the second handle base 2 is a hollow structure with one end open and the other end closed, so as to form a standby pressure on the side of the second handle base 2 for the air sent into the hollow cavity of the handle 10, so that the air flow can be stably blown into the carriage.

[0050] In a specific implementation, the blocking portion 22 is a sheet-shaped blocking portion that blocks the side of the hollow second handle base 2 close to the second fixed end 21. In other specific implementations, the blocking portion can also be arranged in the middle of the hollow second handle base 2 (not shown in the figure), or the blocking portion can also be arranged at the connection end of the rotating handle tube 4 and the second handle base 2, and a certain standby pressure can also be formed on the side close to the second handle base 2.

[0051] Among them, the rotating handle tube 4 rotatably arranged between the first handle base 1 and the second handle base 2 is sleeved outside the hollow inner tube 3. An inner ventilation hole 31 penetrating through its wall is opened on the hollow inner tube 3, and an outer ventilation hole 41 penetrating through its wall is opened on the rotating handle tube 4. When the outer ventilation hole 41 on the rotating handle tube 4 is communicated with the inner ventilation hole 31 on the hollow inner tube 3, an air supply duct P is constructed. In this way, the air flow sent into the hollow cavity can be blown into the carriage from the air supply duct P. In practical applications, based on the structural feature that the rotating handle tube 4 can rotate relative to the hollow inner tube 3, the relative position of the outer ventilation hole 41 can be rotatably adjusted to change the blowing direction.

[0052] Combined withFigure 3 and Figure 4 As shown in Figure 4 , the shape of the outer ventilation holes 41 is rectangular, and along the length direction of the rotary handle tube 4, a plurality of rectangular outer ventilation holes 41 are arranged in a linear array. Correspondingly, along the length direction of the hollow inner tube 3, a plurality of inner ventilation holes 31 can also be arranged in a linear array. Here, the plurality of outer ventilation holes 41 and the plurality of inner ventilation holes 31 can be arranged in one-to-one correspondence.

[0053] In other specific implementations, the outer ventilation holes 41 and the inner ventilation holes 31 can also adopt other arrangement forms. For example, for the shapes of the outer ventilation holes 41 and the inner ventilation holes 31, circular, diamond-shaped or any other shape (not shown in the figure) can be adopted, rather than being limited to rectangular. For another example, for the case where the outer ventilation holes 41 and the inner ventilation holes 31 are respectively configured as a plurality, the two can be arranged in a matrix on the corresponding wall bodies (not shown in the figure), or arranged at irregular intervals on the rotary handle tube 4. It should be understood that as long as the inner ventilation holes 31 and the outer ventilation holes 41 can be ensured to be in a communicating state when the rotary handle tube 4 is rotated to adjust the blowing direction, it is acceptable. The embodiments of the present application do not make any limitations.

[0054] In other possible implementations, the outer ventilation holes 41 and the inner ventilation holes 31 can also be respectively set as a single hole structure. Or, the outer ventilation holes 41 are arranged in a plurality to form a uniform blowing effect; correspondingly, the inner ventilation holes 31 are arranged as a single hole structure that can communicate with the plurality of outer ventilation holes 41 to reduce the wind resistance on the air supply path and reasonably control the efficiency of the air conditioning system.

[0055] In practical applications, one end of the air duct 30 is connected to the open end 12 of the first handle seat 1, and the other end is connected to the pipeline of the air conditioning system (not shown in the figure). The air conditioner provides cold and hot air, which is sent into the hollow cavity of the handle 10 through the air duct 30 and blown out through the air supply channel P to provide cold and hot air for the vehicle occupants, so as to realize the function of reducing or increasing the temperature inside the vehicle. Here, between the air duct 30 and the open end 12 of the first handle seat 1, detachable connection methods such as snap connection or threaded connection can be adopted to facilitate the assembly operation and at the same time facilitate the maintenance. The embodiments of the present application do not make any limitations.

[0056] In addition, in order to improve the system efficiency, a seal 6 can be further provided between the air duct 30 and the open end 12 to prevent the system air supply from escaping.

[0057] To improve the operability of the rotational adjustment, a rotational limit pair can be provided between the rotary handle tube 4 and the hollow inner tube 3. Please refer to Figure 4 , Figure 5 and Figure 6 , where Figure 6 is Figure 4 the partial view in the B direction in

[0058] As shown in the figure, a limiting groove 42 is provided on the wall of the rotating handle tube 4, and a radially protruding limiting convex portion 32 is correspondingly provided on the hollow inner tube 3. The limiting convex portion 32 can be built into the limiting groove 42 to form a rotation limiting pair, thereby determining the rotation stroke of the rotating handle tube 4 relative to the hollow inner tube 3.

[0059] Optionally, the limiting protrusion 32 is arranged on the hollow inner tube 3 on the same side as the first handle seat 1 and the second handle seat 2; in other words, it is arranged on the side of the hollow inner tube 3 close to the interior panel 20, and accordingly, the limiting groove 42 on the rotating handle tube 4 also tends to be arranged on the side of the interior panel 20 to avoid the exposure of the structure affecting the user experience.

[0060] Specifically, in the rotation direction of the rotating handle tube 4, the two side groove walls of the limiting groove 42 are respectively the first limiting surface 421 and the second limiting surface 422. Figure 7 , the figure is Figure 6 CC section view in. Figure 7 The limiting protrusion 32 shown in FIG. 4 is located in the middle of the limiting groove 42 .

[0061] For ease of description, it is defined that when the first limiting surface 421 of the rotating handle tube 4 abuts against one side of the limiting protrusion 32 of the hollow inner tube 3, as shown in FIG. Figure 8 As shown, the rotating handle tube 4 is in the first working position; at the same time, when the second limiting surface 422 of the rotating handle tube 4 is defined to abut against the other side of the limiting protrusion 32 of the hollow inner tube 3, as shown in FIG. Figure 9 As shown, the rotating handle tube 4 is in the second working position. The rotation angle of the rotating handle tube 4 between the first working position and the second working position is also the rotation stroke of the rotating handle tube 4.

[0062] In a specific implementation, within the rotational stroke of the rotating handle tube 4, the outer vent hole 41 and the inner vent hole 31 thereon can always remain connected, that is, the air supply passage P remains unobstructed within the entire stroke.

[0063] In order to further improve the passenger experience, the airway closing function can also be set based on the rotation limit pair. Figure 10 and Figure 11 ,in, Figure 10 Schematic diagram of the conduction state of the air supply duct P. Figure 11 This is a schematic diagram of the closed state of the air supply duct, forming Figure 10 and Figure 11 The cut positions of the cross-sections shown can be found in Figure 4 Section marks shown in DD.

[0064] like Figure 10As shown, the outer vent hole 41 of the rotating handle tube 4 and the inner vent hole 31 of the hollow inner tube 3 are aligned in the radial direction of the hollow inner tube 3, and the air supply passage P is in a conducting state. Figure 10 The relative position relationship between the rotating handle tube 4 and the hollow inner tube 3 shown in FIG. Figure 7 Here, for the relatively arranged outer vent holes 41 and inner vent holes 31, the flow area of ​​the outer vent holes 41 is completely located within the flow area of ​​the inner vent holes 31, and this is the maximum flow outflow.

[0065] It can be understood that, when the outer vent hole 41 and the inner vent hole 31 have the same shape and size, the two can be as follows when the air supply passage P is at the maximum air flow rate. Figure 10 At this time, the rotating handle tube 4 rotates until the limiting protrusion 32 of the hollow inner tube 3 is located in the middle of the limiting groove 42, that is, the rotating handle tube 4 is between the first working position and the second working position.

[0066] When the rotating handle tube 4 rotates counterclockwise or clockwise relative to the hollow inner tube 3, the wall of the hollow inner tube 3 gradually covers the outer vent hole 41, and the air flow rate will gradually decrease. When the rotating handle tube 4 continues to rotate relative to the hollow inner tube 3, until the outer vent hole 41 is staggered with the inner vent hole 31, the wall of the hollow inner tube 3 covers the outer vent hole 41, and the air supply duct is in a state as shown in FIG. Figure 11 Shown in closed position, no air is blown out.

[0067] Figure 11 The relative position relationship between the rotating handle tube 4 and the hollow inner tube 3 shown in FIG. Figure 9 In this state, the rotation limit formed by the contact between the limit protrusion 32 and the second limit surface 422 of the limit groove 42 facilitates the user to perceive and judge when rotating the handle tube, and has good operability.

[0068] In addition, based on Figure 7 and Figure 10 The figure shows the relative position relationship of the maximum air output. The rotating handle tube 4 rotates relative to the hollow inner tube 3 to Figure 8 When in the first working position shown, the air supply duct will also be in a closed state (not shown in the figure). Overall, the user can rotate the rotating handle tube in both directions to rotate it to the closed state.

[0069] In addition, based on Figure 7 and Figure 10 The figure shows the relative position relationship of the maximum air output. The rotating handle tube 4 is rotated to Figure 8 The first working position shown or Figure 9When in the second working position shown in the figure, the air supply duct can have a minimum air output, that is, the outer air vent 41 is connected to a part of the flow area of ​​the inner air vent 31, rather than being limited to the air supply duct closed state shown in the figure.

[0070] For the embodiment with closing function, in other specific implementations, the size of the outer vent hole 41 in the circumferential direction may also be smaller than the size of the inner vent hole 31 in the circumferential direction. Figure 12 , which is a schematic diagram of another matching relationship between the inner vent and the outer vent provided in an embodiment of the present application. Exemplarily, the rotating handle tube 4 shown in (a) is in the first working position shown by the marking line L1, and the flow area of ​​the outer vent 41 on the rotating handle tube 4 is all located in the flow area of ​​the inner vent 31; the rotating handle tube 4 shown in (b) is in the middle working position shown by the marking line L2, and the flow area of ​​the outer vent 41 on the rotating handle tube 4 is all located in the flow area of ​​the inner vent 31; the rotating handle tube 4 shown in (c) is in the second working position shown by the marking line L3, the outer vent 41 on the rotating handle tube 4 is staggered with the inner vent 31, the wall of the hollow inner tube 3 completely gradually covers the outer vent 41, and the air supply duct is in a closed state.

[0071] In this way, within the rotation stroke K of the rotating handle tube 4, it is possible to have a sub-stroke K1 for maintaining the maximum air output when adjusting the blowing direction; that is, when the rotating handle tube 4 rotates within the sub-stroke K1, the flow areas of the outer air holes 41 thereon are all kept connected with the inner air holes 31 and are not blocked by the wall of the hollow inner tube 3; when the rotating handle tube 4 continues to rotate beyond the sub-stroke K1, the wall of the hollow inner tube 3 will gradually block the outer air holes 41, and the air output will gradually decrease until it is completely blocked and in a closed state.

[0072] In other possible implementation schemes, based on the rotation limit pair set between the rotating handle tube 4 and the hollow inner tube 3, the outer vent hole 41 and the inner vent hole 31 can also adopt other arrangements for the first working position and the second working position of the rotating handle tube 4 relative to the hollow inner tube 3.

[0073] In one implementation, when the rotating handle tube 4 is in the first working position, the flow area of ​​the outer vent 41 on the rotating handle tube 4 can be completely located in the flow area of ​​the inner vent 31 (the size of the outer vent 41 in the circumferential direction is smaller than the size of the inner vent 31 in the circumferential direction), or at least overlap with the flow area of ​​the inner vent 31 (the size of the outer vent 41 in the circumferential direction is the same as the size of the inner vent 31 in the circumferential direction); in other words, when the rotating handle tube 4 is in the first working position, the air output is the largest. When the rotating handle tube 4 is in the second working position, the outer vent 41 can be completely staggered with the inner vent 31, and the air supply airway is in a closed state.

[0074] In another implementation, when the rotary handle tube 4 is in the second working position, a partial flow-through area can also be connected between the outer ventilation hole 41 and the inner ventilation hole 31. The outer ventilation hole 41 is not completely shielded by the wall of the hollow inner tube 3, and the air supply duct has a minimum air output volume.

[0075] In other possible implementation solutions, the limiting convex portion 32 and the limiting groove 42 that form the rotational limiting pair can also be reversely arranged on the rotary handle tube 4 and the hollow inner tube 3 (not shown in the figure); that is to say, for the matching limiting convex portion and limiting groove, the limiting convex portion can be arranged on the side of the rotary handle tube, and correspondingly, the limiting groove can be arranged on the hollow inner tube. Specifically, it can be determined according to the overall design requirements of the product, and the embodiments of the present application do not make any limitations.

[0076] Furthermore, in order to improve the blowing effect, sealing rings 5 can be arranged between the two end portions of the rotary handle tube 4 and the hollow inner tube 3. As shown in Figure 4 and Figure 5 , the sealing ring 5 is located at a position far from the air supply duct P. The sealing ring 5 can be deformed under pressure after assembly to form a reliable sealing relationship between the rotary handle tube 4 and the hollow inner tube 3. In this way, the air flow sent into the hollow cavity of the handle can only be blown into the vehicle compartment through the inner ventilation hole 31 and the outer ventilation hole 41 that are far from the air supply duct P, so that a better blowing effect can be obtained under the same system air supply parameters.

[0077] In this implementation solution, a sealing groove 33 is provided on the hollow inner tube 3 for installing the sealing ring 5. It can be understood that the sealing groove 33 and the sealing ring 5 are arranged in one-to-one correspondence, and the specific number of settings can be determined according to needs, rather than being limited to two provided at each end as shown in the figure. The embodiments of the present application do not make any limitations.

[0078] In addition, based on the setting of the sealing ring 5, in addition to the sealing function, during the process of rotating the rotary handle tube 4, the sealing ring 5 deformed under pressure can also synchronously provide a certain frictional resistance, and the rotation feeling is better; in addition, the setting of the sealing ring 5 can also support the rotary handle tube 4 to maintain a determined adjustment position, avoiding the rotary handle tube 4 deviating from the determined position adjusted by the occupant due to vibration during vehicle driving.

[0079] In order to obtain the flatness of the outer surface of the handle, at the connection position between the hollow inner tube 3 and the first handle seat 1, there is a first step surface S1, and at the connection position between the hollow inner tube 3 and the second handle seat 2, there is a second step surface S2. The first step surface S1 and the second step surface S2 are respectively formed by inwardly converging from the corresponding handle seat towards the hollow inner tube 3; that is to say, the outer diameter dimension of the hollow inner tube 3 is smaller than the dimension of the connection end of the handle seat opposite to it. At the same time, the outer peripheral surface of the rotating handle tube 4 can be flush with the connection ends of the opposite first handle seat 1 and the second handle seat 2 respectively. In this way, the overall appearance has a smooth transition, and at the same time, it can avoid affecting the user's hand feeling during the process of rotating the rotating handle tube 4.

[0080] It should be noted that the rotating handle tube 4 shown in the figure is cylindrical, and its outer peripheral surface is flush with the connection end of the handle seat as a whole along the axial direction. In other possible implementation manners, the outer peripheral surface of the rotating handle tube 4 can also be a non-cylindrical surface, such as but not limited to having a local concave arc that meets the holding hand feeling and other forms. For the rotating handle tube 4 with a non-cylindrical outer peripheral surface, as long as the two ends of the outer peripheral surface of the rotating handle tube 4 are flush with the connection ends of the opposite handle seats, good appearance consistency can be obtained. The embodiments of the present application do not make limitations.

[0081] In a specific implementation, the first handle seat 1, the second handle seat 2, and the hollow inner tube 3 can be made by an integral molding process, and the process cost is relatively low. In other possible implementation manners, the three can also be separately processed and then fixedly connected. It can be understood that as long as a hollow cavity for air supply can be formed, the embodiments of the present application do not make limitations.

[0082] Specifically, the first fixed end 11 of the first handle seat 1 and the second fixed end 21 of the second handle seat 2 can adopt different fixing structures. For example but not limited to, the first fixed end 11 and the second fixed end 21 can be connected to the fixing member through a clamping structure, or through a threaded fastener to the fixing member, or by using a welding process to connect to the fixing member.

[0083] Again Figures 1 to 4 As shown, exemplarily, the first fixed end 11 and the second fixed end 21 of the present implementation scheme are fixedly connected to the interior trim panel 20 by a welding process. Among them, the first fixed end 11 includes a first fitting plate 111 and two fixed point portions 112, and the fixed point portions 112 are located on the side of the first fitting plate 111 close to the interior trim panel 20; the second fixed end 21 includes a second fitting plate 121 and two fixed point portions 122, and the fixed point portions 122 are located on the side of the second fitting plate 121 close to the interior trim panel 20.

[0084] During the assembly operation, the first fitting plate 111 and the second fitting plate 121 can be respectively fitted with the interior trim panel 20 to provide reliable pre-positioning before welding. At the same time, the four fixing point parts (two fixing point parts 112 and two fixing point parts 122) can pass through the interior trim panel 20 and be welded and fixed. Specifically, it can be realized by using the existing technology, which will not be elaborated here.

[0085] The aforementioned Figure 1 handle solution described is based on the internal ventilation holes 31 opened on the hollow inner tube 3 and the external ventilation holes 41 opened on the rotating handle tube 4, and the formed air supply duct P blows into the vehicle compartment. Please refer to Figure 13 and Figure 14 , where Figure 13 is a schematic assembly relationship diagram of another handle provided by an embodiment of the present application, Figure 14 is Figure 13 an exploded assembly diagram of the handle shown in. In order to clearly show the differences and connections between this embodiment and Figure 1 the embodiment described, components and structures with the same functions are schematically indicated by the same marks in the figure.

[0086] Compared with Figure 1 the handle described, the difference in this implementation scheme is that the rotating handle tube 4 is respectively rotationally adapted to the first handle seat 1 and the second handle seat 2, and no hollow inner tube 3 is provided between the first handle seat 1 and the second handle seat 2.

[0087] As Figure 13 and Figure 14 shown, both ends of the rotating handle tube 4 are respectively inserted into the first handle seat 1 and the second handle seat 2. The first insertion tube section 43 at one end of the rotating handle tube 4 is rotationally connected to the first handle seat 1, and the second insertion tube section 44 at the other end of the rotating handle tube 4 is rotationally connected to the second handle seat 2. The external ventilation holes 41 opened on the body of the rotating handle tube 4 form the air supply duct P. It has the characteristics of simple and reliable structure.

[0088] In this way, the air conditioner provides hot and cold air, which is sent into the hollow cavity of the handle 10 through the air duct 30 and blown out through the external ventilation holes 41 to provide hot and cold air for the vehicle occupants, and can also reliably achieve the function of reducing or increasing the temperature inside the vehicle.

[0089] In order to obtain the flatness of the outer surface of the handle, the connection position between the body of the rotating handle tube 4 and the first insertion tube section 43 has a third connection surface S3, and the connection position between the body of the rotating handle tube 4 and the second handle seat 2 has a fourth connection surface S4. The outer peripheral surface of the body of the rotating handle tube 4 is flush with the connection ends of the opposite first handle seat 1 and the second handle seat 2 respectively. In this way, the overall appearance has a smooth transition, and at the same time, it can avoid affecting the user's hand feeling during the process of rotating the rotating handle tube 4.

[0090] In other specific implementations, an insertion and adaptation relationship can also be configured in the reverse direction between the rotating handle tube 4 and the first handle seat 1 and the second handle seat 2. That is to say, the first handle seat 1 and the second handle seat 2 are respectively inserted at both ends of the rotating handle tube 4 and are rotatably connected. Specifically, it can be determined according to the overall design requirements of the product, and the embodiments of the present application do not make any limitations.

[0091] In addition to the foregoing handle implementation solutions, the embodiments of the present application also provide a vehicle, which includes a vehicle body 40 and an interior trim panel 20 located inside the vehicle body 40, and also includes an air duct 30 and the handle 10 as described above. The air duct 30 is located outside the interior trim panel 20, and the handle 10 is fixedly arranged on the interior trim panel 20 or the vehicle body 40.

[0092] In a specific implementation, the handle 10 can be arranged at positions such as a car door, a car roof or a center console. Based on the configuration of the handle, air flow can be sent into the hollow cavity of the handle through the first handle seat and blown into the carriage through the external ventilation holes on the rotating handle tube. On the basis of providing a holding function, the blowing function can be realized at the same time to meet the comfort requirements of the occupants. In addition, integrating the blowing function on the handle can reduce the occupation of the interior space of the vehicle at the same time; and the blowing direction can be adjusted according to the needs of the occupants, further improving the comfort.

[0093] It should be understood that other functional components of the vehicle can be implemented by using the prior art, so they will not be elaborated here.

[0094] In addition, the ordinal numbers "first" and "second" used herein are only used to describe components or structures with the same function in the technical solution. It can be understood that the use of the above ordinal numbers does not constitute a limitation to the understanding of the technical solution claimed in the present application.

[0095] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
