Description

Technical Field

[0001] This invention relates to the field of air conditioning vent technology, and more particularly to a connecting device, an air conditioning vent structure, and a vehicle. Background Technology

[0002] The air vent assembly serves as the terminal of the vehicle's air conditioning system. Air from the air conditioning duct is delivered into the passenger compartment through the air vent assembly to heat or cool the passenger compartment.

[0003] During the design phase, the air conditioning ducts are often curved due to the overall vehicle space layout. When the fan is activated, the airflow velocity distribution across the duct cross-section is uneven, resulting in uneven airflow velocity distribution at the air outlet assembly cross-section as well. Currently, workers typically address this issue by rotating the air outlet assembly to change its circumferential installation angle relative to the air conditioning duct. The specific circumferential rotation angle is determined based on the worker's experience.

[0004] However, relying on workers' operational experience cannot guarantee the accuracy of the circumferential installation position of the air outlet assembly, which will still lead to uneven air outlet speed and large pressure loss, thus affecting the performance of the air conditioner and the comfort of the passenger cabin. Summary of the Invention

[0017] The second clamp is used to fix the transition connecting pipe to the rotating assembly.

[0018] According to the connection device provided by the present invention, the transition connection pipe is a corrugated pipe or a flexible hose.

[0019] The present invention also provides an air conditioner outlet structure, comprising:

[0020] An air conditioning duct and air outlet assembly, wherein the circumferential installation angle of the air outlet assembly relative to the air conditioning duct is adjustable by a connecting device as described in any of the preceding claims, the connecting device being detachably connected between the air conditioning duct and the air outlet assembly.

[0021] The air conditioner outlet structure provided by the present invention further includes:

[0022] Interior trim piece, disposed at the end of the air outlet assembly away from the air conditioning duct, the interior trim piece being used to install the air outlet assembly;

[0023] A positioning device is used to position and install the air outlet assembly and the interior trim after determining the circumferential installation angle of the air outlet assembly.

[0024] According to the air conditioning outlet structure provided by the present invention, the positioning device includes:

[0025] A connector is provided on the peripheral sidewall of the air outlet assembly;

[0026] A snap-fit ​​component is used to snap onto the interior trim component. The snap-fit ​​component is slidably connected to the connector, and the snap-fit ​​component can move along the axial direction of the connector.

Due to the uneven distribution of airflow velocity across the duct cross-section, a pressure difference occurs.

This aerodynamic approach, using a connecting device, allows for precise adjustment of the circumferential installation angle of the air outlet assembly, eliminating the unevenness of airflow velocity. Its simple structure, convenient and flexible operation, and effective improvement of air conditioning performance enhance passenger cabin comfort. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0043] The following is combined with Figures 1 to 7 The connecting device of the present invention is described.

[0044] like Figures 1 to 7 As shown, this embodiment of the invention provides a connecting device for adjusting the circumferential installation angle of the air outlet assembly 1 relative to the air conditioning duct 2. The connecting device is connected between the air conditioning duct 2 and the air outlet assembly 1. Specifically, the connecting device includes a transition connecting pipe 3 and a rotating assembly. Figure 1 As shown, the two ends of the transition connecting pipe 3 are respectively sleeved on the air conditioning duct 2 and the air outlet assembly 1. Specifically, the transition connecting pipe 3 is sleeved on the outside of the air conditioning duct 2 and the air outlet assembly 1, which is more conducive to the airflow from the duct to the air outlet.

[0045] like Figure 1As shown, a rotating assembly is disposed between the air outlet assembly 1 and the transition connecting pipe 3. The rotating assembly includes a first ring body 4 and a second ring body 5. The second ring body 5 is sleeved on the first ring body 4 and is rotatable relative to the first ring body 4. One of the first ring body 4 and the second ring body 5 is fixedly connected to the air outlet assembly 1, and the other is fixedly connected to the transition connecting pipe 3. That is, the first ring body 4 is fixedly connected to the air outlet assembly 1, and the second ring body 5 is fixedly connected to the transition connecting pipe 3. Alternatively, the first ring body 4 is fixedly connected to the transition connecting pipe 3, and the second ring body 5 is fixedly connected to the air outlet assembly 1. Specifically, taking... Figure 1 As shown in the example, the first ring 4 is fixedly connected to the air outlet assembly 1, and the second ring 5 is fixedly connected to the transition connecting pipe 3. For example, a tight connection can be achieved through an interference fit, which facilitates the assembly of rotating components. Generally, if the air outlet assembly 1 is designed as a circular air outlet, then the inner ring of the first ring 4 is correspondingly set to a circle. If the air outlet assembly 1 is designed as a square air outlet, then the inner ring of the first ring 4 is correspondingly set to a square, so that the first ring 4 is in close contact with the air outlet assembly 1, facilitating the rotation and adjustment of the air outlet assembly 1.

[0046] In this configuration, the air conditioning duct 2 and the air outlet assembly 1 are connected together via a transition connecting pipe 3. Due to the uneven distribution of airflow velocity across the duct cross-section, a pressure difference occurs. Under the influence of this pressure difference, the two rings of the rotating component rotate relative to each other, thereby causing the air outlet assembly 1 to rotate synchronously. This changes the circumferential installation angle of the air outlet assembly 1 relative to the air conditioning duct 2, eventually bringing it to a balanced position. The air outlet assembly 1 is then positioned and installed according to this balanced position. This aerodynamic approach, utilizing the connecting device, allows for precise adjustment of the circumferential installation angle of the air outlet assembly 1, eliminating the unevenness of the air outlet velocity. Its structure is simple, operation is convenient and flexible, effectively improving air conditioning performance and enhancing passenger cabin comfort, making it easy to apply and promote.

[0047] In this embodiment of the invention, the connecting device further includes an annular wind baffle 6, which is located on the side of the rotating assembly near the air conditioning duct 2, i.e., as shown in the figure. Figure 1 As shown, the annular baffle 6 is located on the right side of the rotating assembly. The annular baffle 6 is sleeved on the air outlet assembly 1, and is positioned between the air outlet assembly 1 and the transition connecting pipe 3. The annular baffle 6 is connected to one of the first ring body 4 and the second ring body 5. That is, the annular baffle 6 can be connected to the first ring body 4, or the annular baffle 6 can be connected to the second ring body 5. Specifically, with... Figure 1As shown in the example, the annular baffle 6 can be connected to the second ring 5. The cross-section of the annular baffle 6 is "L" shaped, and its short side can be fixed to the second ring 5 by welding, while the long side can be used to block the airflow. It should be noted that a certain gap can be appropriately left between the inner ring of the annular baffle 6 and the outer wall of the air outlet assembly 1 to avoid friction between the two when relative rotation occurs, thus preventing the air outlet assembly 1 from rotating circumferentially.

[0048] This configuration, with the annular baffle 6 acting as a windbreak, directs airflow towards the air outlet assembly 1, improving the accuracy of circumferential angle adjustment. It should be noted that, as shown in... Figure 1 Regarding the placement of the connecting device shown, the left and right directions in the diagram refer to the left and right positions.

[0049] Furthermore, in this embodiment of the invention, the connecting device further includes a sealing element 7, which is disposed between the rotating assembly and the air outlet assembly 1. Specifically, as shown... Figure 1 As shown, the seal 7 can be a rubber seal with a "U" shaped cross-section, covering the first ring 4 and sealingly engaging the first ring 4 with the air outlet assembly 1. This arrangement, by filling the space between the first ring 4 and the air outlet assembly 1 with the seal 7, achieves a sealed connection, preventing gas leakage from the joint and further improving the accuracy of the circumferential position adjustment of the air outlet.

[0050] As an optional embodiment of the present invention, the rotating assembly further includes at least two rotating beads 8, each rotating bead 8 being rotatably connected between the first ring body 4 and the second ring body 5. Specifically, each rotating bead 8 is evenly distributed circumferentially along the air outlet assembly 1. Correspondingly, the first ring body 4 and the second ring body 5 are provided with receiving grooves adapted to each rotating bead 8. Specifically, the receiving grooves can be designed as arc-shaped grooves for tighter contact. With this arrangement, by filling the space between the two ring bodies with several rotating beads 8, the rotation between them becomes more flexible and smooth, facilitating circumferential adjustment of the air outlet.

[0051] In a specific embodiment of the present invention, the connecting device further includes a first clamp 9 and a second clamp 10. For example... Figure 2 As shown, the first clamp 9 is used to fix one end of the transition connecting pipe 3 to the air conditioning duct 2. Specifically, as... Figure 3 As shown, the first clamp 9 is an open ring for easy installation. The first clamp 9 is placed over the transition connecting pipe 3 and then tightened with connecting bolts 91 and connecting nuts 92 to fix the transition connecting pipe 3 and the air conditioning duct 2 together, making it easy to disassemble and assemble.

[0052] like Figure 2As shown, the second clamp 10 is used to fix the other end of the transition connecting pipe 3 to the rotating assembly. Specifically, the second clamp 10 has the same structure as the first clamp 9. The second clamp 10 is fitted over the transition connecting pipe 3 and then tightened with bolts and nuts to fix the transition connecting pipe 3 and the second ring 5 together. This causes the first ring 4 to drive the air outlet assembly 1 to rotate relative to the second ring 5, thus achieving circumferential rotation of the air outlet assembly 1 relative to the air conditioning duct 2.

[0053] In an optional embodiment of the present invention, the transition connecting pipe 3 is a corrugated pipe or a flexible hose. This configuration allows the transition connecting pipe 3 to bend and adjust according to the spatial arrangement when adjusting the circumferential installation position of the air outlet, facilitating the connection between the air outlet assembly 1 and the air conditioning duct 2.

[0054] The air conditioner outlet structure provided by the present invention is described below. The air conditioner outlet structure described below can be referred to in correspondence with the connecting device described above.

[0055] This invention also provides an air conditioning outlet structure, such as... Figure 5 As shown, it includes an air conditioning duct 2 and an air outlet assembly 1. To eliminate the unevenness of the air outlet cross-section's air velocity, the circumferential installation angle of the air outlet assembly 1 relative to the air conditioning duct 2 is adjusted using a connecting device as described in the above embodiments, wherein the connecting device is detachably connected between the air conditioning duct 2 and the air outlet assembly 1. This arrangement, as shown... Figure 2 As shown, the air conditioning duct 2 is connected to the air outlet assembly 1 via a connecting device. Due to the uneven distribution of airflow velocity across the duct cross-section, a pressure difference occurs. Under the influence of this pressure difference, the two rings of the rotating component rotate relative to each other, thereby causing the air outlet assembly 1 to rotate synchronously. This changes the circumferential installation angle of the air outlet assembly 1 relative to the air conditioning duct 2, eventually bringing it to a balanced position. The air outlet assembly 1 is then positioned and installed according to this balanced position. This utilizes aerodynamic principles, allowing the connecting device to quickly and accurately find the optimal circumferential installation angle of the air outlet, eliminating the unevenness of the airflow velocity. Its structure is simple, operation is convenient and flexible, effectively improving air conditioning performance and enhancing passenger cabin comfort. The derivation process for this beneficial effect is roughly similar to that of the connecting device described above, and therefore will not be repeated here.

[0056] It should be noted that after determining the circumferential angle of the air outlet, record the position of the circumferential angle of the air outlet. Then, the connecting device can be removed, and the air outlet can be installed and positioned according to the recorded position. Figure 5As shown, a filler 13, such as a sponge, can be placed between the air outlet assembly 1 and the air conditioning duct 2 to seal the connection point and improve the air tightness of the air outlet structure. Of course, the connecting device can also be applied directly to the connection point between the duct and the air outlet without removing it, as long as it meets the overall vehicle space layout requirements.

[0057] In this embodiment of the invention, the air conditioning vent structure also includes interior trim 11 and positioning device 12. For example... Figure 5 As shown, the interior trim component 11 is located at the end of the air outlet assembly 1 furthest from the air conditioning duct 2. The interior trim component 11 is used to mount the air outlet assembly 1 and has mounting holes adapted to the air outlet assembly 1. After determining the circumferential mounting angle of the air outlet assembly 1, the positioning device 12 is used to position and install the air outlet assembly 1 and the interior trim component 11, thereby ensuring that the air outlet is fixed to the interior trim component 11 at the optimal mounting angle, improving the performance of the air conditioning system. To ensure reliable installation of the air outlet assembly 1, the number of positioning devices 12 can be at least two, with each positioning device 12 evenly spaced along the circumference of the air outlet assembly 1. The number of positioning devices 12 can be determined according to actual design requirements.

[0058] In a specific embodiment of the present invention, the positioning device 12 includes a connector 121, a snap-fit ​​member 122, an elastic clamping member 123, and a plurality of positioning members 111. For example... Figure 6 As shown, the connector 121 is disposed on the peripheral sidewall of the air outlet assembly 1. Specifically, as... Figure 7 As shown, the connector 121 includes an injection-molded part 1211 and a screw 1212. Generally, the air outlet assembly 1 is injection-molded, and the injection-molded part 1211 can be integrally molded with the air outlet for easy processing and manufacturing. The screw 1212 is embedded in the injection-molded part 1211 for connection with other components.

[0059] The snap-fit ​​member 122 is used to snap onto the interior trim piece 11 to achieve a fixed connection with it. The snap-fit ​​member 122 is slidably connected to the connector 121, and the snap-fit ​​member 122 moves axially along the connector 121. Specifically, as... Figure 7 As shown, the snap-fit ​​member 122 slides on the screw 1212, and a guide mechanism is provided between the snap-fit ​​member 122 and the screw 1212. The guide mechanism includes a matching guide groove 1213 and a protrusion 1222. One of the snap-fit ​​member 122 and the screw 1212 has the protrusion 1222, and the other has the guide groove 1213. Figure 7 For example, the snap-fit ​​part 122 is provided with a protrusion 1222, and the screw 1212 is provided with a guide groove 1213, thereby ensuring that the snap-fit ​​part 122 moves stably in a straight line on the screw 1212. In addition, the snap-fit ​​part 122 is also provided with an inclined guide part 1221, so that when the air outlet assembly 1 is pressed into the interior trim 11, the snap-fit ​​part 122 can pass through the mounting holes on the interior trim 11.

[0060] The elastic clamping member 123 can be a spring, sleeved on the connecting member 121. The elastic clamping member 123 is used to press the snap-fit ​​member 122 onto the interior trim member 11. One end of the elastic clamping member 123 abuts against the snap-fit ​​member 122, and the other end abuts against the connecting member 121. Specifically, a locking nut 124 is connected to the lower end of the screw 1212. The upper end of the spring abuts against the lower surface of the snap-fit ​​member 122, and the lower end abuts against the locking nut 124, so that the snap-fit ​​member 122 can be pressed against the lower surface of the interior trim member 11 by the spring force.

[0061] like Figure 4 As shown, a number of positioning elements 111 are disposed on the interior trim 11. Each positioning element 111 is distributed circumferentially along the air outlet assembly 1, and a limiting gap is formed between two adjacent positioning elements 111 to match the snap-fit ​​element 122. Specifically, the positioning elements 111 can be configured as protrusions on the lower surface of the interior trim 11. Their number, size, shape, and other parameters can be determined according to actual design requirements. For example, they can be spherical protrusions. The distance between two adjacent spherical protrusions is slightly greater than the thickness of the snap-fit ​​element 122 to facilitate the limiting and fixing of the snap-fit ​​element 122.

[0062] In addition, the positioning device 12 also includes an elastic reset member 125, which may be a spring. The elastic reset member 125 is sleeved on the connecting member 121, specifically, on the screw 1212. Figure 6 As shown, the upper end of the connector 121 has a stepped surface, the upper end of the elastic reset member 125 abuts against this stepped surface, and the lower end of the elastic reset member 125 abuts against the upper surface of the snap-fit ​​member 122 to assist the movement of the snap-fit ​​member 122. It should be noted that, as shown... Figure 5 and Figure 6 Regarding the placement of the air conditioning vent structure shown, the up-down direction in the diagram refers to the upper and lower positions indicated, and the axial direction of the connector 121; for example... Figure 7 Regarding the placement of the air conditioning vent structure shown, the left and right directions in the figure correspond to the thickness direction of the snap-fit ​​component 122.

[0063] Specifically, when the air vent assembly 1 is not assembled with the interior trim piece 11, the snap-fit ​​member 122 is not subjected to external force, and the elastic clamping member 123 and the elastic resetting member 125 are in a free state. During the process of pressing the air vent assembly 1 into the interior trim piece 11, as shown... Figure 5As shown, when the air outlet assembly 1 is pressed down, the snap-fit ​​member 122 contacts the upper edge of the mounting hole of the interior trim 11 and gradually moves upward on the screw 1212. At this time, the snap-fit ​​member 122 acts on the upper elastic reset member 125, which is in a compressed state, while the lower elastic clamping member 123 is in a free state. When the air outlet assembly 1 is pressed into the interior trim 11, the upper elastic reset member 125 recovers its deformation, causing the snap-fit ​​member 122 to gradually move downward on the screw 1212. At this time, the upper elastic reset member 125 is in a free state, while the lower elastic clamping member 123 is in a compressed state. The lower elastic clamping member 123 presses the snap-fit ​​member 122 against the lower surface of the interior trim 11, thus completing the axial fixation of the air outlet assembly 1. At the same time, according to the determined circumferential installation angle, the snap-fit ​​122 is placed between the two positioning pieces 111 at the corresponding positions, thus completing the circumferential positioning of the air outlet assembly 1.

[0064] Additionally, when disassembling the air outlet assembly 1, grasp the middle of the air outlet assembly 1 and pull it upwards with force. At this time, the lower elastic clamping member 123 will be further compressed, and the locking member 122 will move downwards until the air outlet is pulled out. To facilitate the removal of the air outlet, such as Figure 6 As shown, a chamfer can be provided on the upper end of the snap fastener 122. When the upper end of the snap fastener 122 contacts the lower edge of the mounting hole of the interior trim 11, it is convenient for the snap fastener 122 to slide out of the mounting hole.

[0065] This design allows for easy installation and removal of the air outlet via the aforementioned positioning device 12, making it flexible and convenient to use.

[0066] The vehicle provided by the present invention is described below. The vehicle described below can be referred to in correspondence with the air conditioning vent structure described above.

[0067] This invention also provides a vehicle including an air conditioning vent structure as described in the above embodiments. In this configuration, the air conditioning duct 2 and the vent assembly 1 are connected together via a connecting device. Due to the uneven distribution of airflow velocity across the duct cross-section, a pressure difference occurs. Under this pressure difference, the two rings of the rotating assembly rotate relative to each other, thereby causing the vent assembly 1 to rotate synchronously. This changes the circumferential installation angle of the vent assembly 1 relative to the air conditioning duct 2, eventually bringing it to a balanced position. The vent assembly 1 is then positioned and installed according to this balanced position. This utilizes aerodynamic principles, allowing for a quick and accurate determination of the optimal circumferential installation angle of the vent through the connecting device, eliminating the unevenness of the airflow velocity. The structure is simple, easy and flexible to operate, effectively improving air conditioning performance and enhancing passenger cabin comfort. The derivation process for this beneficial effect is roughly similar to that of the air conditioning vent structure described above, and therefore will not be repeated here.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
