Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive light-emitting air vent. Background Technology

[0002] The automotive air conditioning system is a crucial component of vehicle comfort features. Its function is to regulate the temperature, humidity, and airflow within the vehicle to provide a comfortable environment for passengers. As the terminal component of the air conditioning system, the air vents directly affect the distribution and regulation of airflow. In recent years, illuminated decorations have become increasingly common in automotive interiors. Illuminated automotive air vents typically have an vent housing. To synchronize their illumination with the illuminated decorations in the interior, a ring of LEDs is usually installed at the front outlet of the vent housing.

[0003] Regarding the aforementioned technologies, the direct use of light strips for illumination can cause glare to the driver's eyes, indicating room for improvement. Utility Model Content

[0004] In order to reduce the probability of causing glare to drivers, this application provides a car luminous air vent.

[0005] The technical solution for a car luminous air vent provided in this application is as follows:

[0006] An automotive luminous air vent includes an air vent housing with an air inlet, an air outlet, and an air outlet channel connecting the air inlet and the air outlet. It also includes an air outlet adjustment mechanism disposed in the air outlet channel for adjusting the air outlet direction, and a light-emitting mechanism disposed in the air vent housing near the air outlet. The light-emitting mechanism includes a light-transmitting plate disposed in the air vent housing near the air outlet, a light guide strip circumferentially surrounding the back side of the light-transmitting plate, and a light-emitting part connected to the light guide strip for emitting light to the light guide strip. The opening of the light-transmitting plate gradually increases in size from the air inlet towards the air outlet, and the light-transmitting plate is circumferentially provided with a light-transmitting window corresponding to the light guide strip.

[0007] By adopting the above technical solution, a light-emitting mechanism is installed on the side of the air outlet housing near the air outlet. The light-emitting part emits light towards the light guide strip, causing the light guide strip to light up. By setting a light-transmitting window on the light-transmitting plate corresponding to the light guide strip, when the light guide strip is lit, the light can only pass through the light-transmitting window. Furthermore, since the opening of the light-transmitting plate gradually increases from the air inlet to the air outlet, the light passing through the light-transmitting window is less likely to directly shine into the driver's eyes, thereby reducing the probability of the light-emitting mechanism causing glare to the driver when it is lit.

[0008] Optionally, the end sidewall of the light guide strip is symmetrically provided with snap-fit ​​protrusions, and the light-emitting part has an insertion hole for inserting the light guide strip, and a snap-fit ​​hole is provided on the sidewall of the insertion hole for engaging with the snap-fit ​​protrusions.

[0009] By adopting the above technical solution, the connection structure between the light guide strip and the light-emitting part is disclosed. The cooperation between the snap-fit ​​protrusion and the snap-fit ​​hole makes the installation of the light guide strip and the light-emitting part relatively simple.

[0010] Optionally, the air outlet housing has multiple mounting clips circumferentially arranged on one side near the air outlet, the mounting clips having mounting slots, and the light guide strip is arranged in the mounting slots.

[0011] By adopting the above technical solution, the installation slot design helps to ensure the ideal stability of the light guide strip after installation, reducing the probability of the light guide strip shifting during vehicle operation.

[0012] Optionally, the air outlet adjustment mechanism includes a horizontal adjustment component and a vertical adjustment component; the horizontal adjustment component includes multiple horizontal blades arranged horizontally and rotatably mounted in the air outlet channel near one end of the air outlet, a first synchronous link connecting the multiple horizontal blades, an adjustment knob horizontally slidably mounted on one of the horizontal blades, and a drive lever rotatably mounted in the adjustment knob facing the side of the vertical adjustment component; the vertical adjustment component includes multiple vertical blades arranged vertically and rotatably mounted in the air outlet housing, and a second synchronous link connecting the bottom of the multiple vertical blades; the drive lever has a drive groove opening facing the side of the vertical adjustment component, and one of the vertical blades is provided with a drive rod for slidingly engaging with the drive groove.

[0013] By adopting the above technical solution, the specific structure of the air outlet adjustment mechanism is disclosed. The adjustment knob can drive one of the horizontal blades to rotate, which in turn drives the first synchronous link to swing. The first synchronous link can drive the remaining horizontal blades to rotate synchronously. By sliding the adjustment lever on the horizontal blade, the drive lever can be moved. Since the drive rod is arranged in the drive groove of the drive lever, it can drive the vertical blade to rotate. The vertical blade can drive the second synchronous link to swing, and the second synchronous link can drive the remaining vertical blades to rotate.

[0014] Optionally, the air outlet housing is provided with a diffuser ring at the air outlet, and the opening of the diffuser ring gradually increases from the air inlet toward the air outlet.

[0015] By adopting the above technical solution, the diffuser ring is designed so that when the horizontal or vertical blades rotate and the airflow direction changes, the air can be blown towards the cockpit along the side wall of the diffuser ring, making the blown air more uniform.

[0016] Optionally, the light-transmitting plate and the air outlet housing are connected by a snap-fit ​​structure; the snap-fit ​​structure includes a plurality of snap-fit ​​pieces circumferentially spaced on the back side of the light-transmitting plate and a snap-fit ​​assembly disposed on the outer side wall of the air outlet housing near the light-transmitting plate and arranged in a one-to-one correspondence with the plurality of snap-fit ​​pieces; the snap-fit ​​piece includes a snap-fit ​​body connected to the light-transmitting plate, a connecting part connected to the snap-fit ​​body, and a limiting part connected to the connecting part; the snap-fit ​​assembly includes a snap-fit ​​seat and a limiting protrusion; the snap-fit ​​seat has a snap-fit ​​groove for the snap-fit ​​piece to pass through, and the limiting protrusion has an abutting surface for abutting against the side of the limiting part facing the light-transmitting plate and a guide surface for guiding the limiting part away from the snap-fit ​​seat.

[0017] By adopting the above technical solution, a connection structure between the light-transmitting plate and the air outlet housing is disclosed. When installing the light-transmitting plate, the snap-fit ​​piece passes through the snap-fit ​​groove of the snap-fit ​​seat, causing the limiting part to abut against the guide surface of the limiting protrusion. Then, the light-transmitting plate is further pushed, and the limiting part is lifted by the limiting protrusion under the action of the guide surface. When the limiting part has completely passed the limiting protrusion, the side of the limiting part facing the light-transmitting plate abuts against the abutment surface of the limiting protrusion, thereby limiting the limiting part and fixing the connection between the snap-fit ​​piece and the snap-fit ​​assembly.

[0018] Optionally, the limiting portion has an inclined surface at the bottom of one end away from the connecting portion that mates with the guide surface.

[0019] By adopting the above technical solution, the inclined surface helps to make the limiting part more easily lifted when passing the limiting protrusion.

[0020] Optionally, the snap-fit ​​piece has a reinforcing rib on one end face facing away from the outer wall of the air outlet housing and along its length, and the reinforcing rib extends from the snap-fit ​​body to the connecting part.

[0021] By adopting the above technical solution, the setting of the reinforcing rib makes it less likely for the limiting part to bend or break when it is lifted, and allows the limiting part to quickly reset and abut against the outer wall of the air outlet housing when it passes the limiting protrusion.

[0022] Optionally, the snap-fit ​​tab is provided with a plurality of positioning tabs spaced apart on the back side, and the air outlet housing is provided with positioning grooves that correspond one-to-one with the plurality of positioning tabs.

[0023] By adopting the above technical solution, the positioning piece and positioning groove are designed to ensure accurate engagement between the snap-fit ​​piece and the snap-fit ​​assembly.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A car luminous air vent, wherein a light-emitting mechanism is provided on the air vent housing, the light-emitting part emits light through a light guide strip, and after the light guide strip is lit, the light can only be transmitted through the light-transmitting window. Furthermore, since the opening of the light-transmitting plate gradually increases from the air inlet to the air outlet, the light is less likely to directly shine into the driver's eyes, thus reducing the probability of causing glare.

[0026] 2. By setting mounting clips on the air outlet housing, the light guide strip can be placed in the mounting slot, resulting in a more ideal installation effect;

[0027] 3. The light-transmitting panel and the air outlet housing are connected by a snap-fit ​​structure, making the installation of the light-transmitting panel relatively simple. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0040] This application discloses an automotive luminous air vent.

[0041] Reference Figure 1 and Figure 2 The automotive illuminated air vent includes an air vent housing 1, an air vent adjustment mechanism 2, and an illuminating mechanism 3. The air vent housing 1 has an air inlet 11, an air outlet 12, and an air outlet channel 13 connecting the air inlet 11 and the air outlet 12. The air vent adjustment mechanism 2 is installed in the air outlet channel 13, and the illuminating mechanism 3 is installed in the air vent housing 1 on the side near the air outlet 12.

[0042] Reference Figure 1 and Figure 2 The air outlet adjustment mechanism 2 includes a horizontal adjustment component 21 and a vertical adjustment component 22. The horizontal adjustment component 21 is located on the side closer to the air outlet 12, and the vertical adjustment component 22 is located on the side closer to the air inlet 11.

[0043] Reference Figure 3 and Figure 4The horizontal adjustment assembly 21 includes multiple horizontal blades 211 arranged horizontally side-by-side and rotatably mounted on the air outlet housing 1, a first synchronous connecting rod 212 connecting the multiple horizontal blades 211 towards the vertical adjustment assembly 22, an adjustment knob 213 horizontally slidably mounted on one of the horizontal blades 211, and a drive lever 214 rotatably mounted on the adjustment knob 213 towards the vertical adjustment assembly 22. In this embodiment, there are three horizontal blades 211. The horizontal blade 211 located in the middle position of the three horizontal blades 211 has an adjustment groove 2111 along its length. The adjustment knob 213 includes a knob portion 2131 arranged in the adjustment groove 2111 facing away from the vertical adjustment assembly 22, a sliding portion 2132 arranged in the adjustment groove 2111 near the vertical adjustment assembly 22, and a sliding plate 2133 connecting the knob portion 2131 and the sliding portion 2132 and slidably arranged in the adjustment groove 2111. The drive lever 214 is mounted on the sliding part 2132 for up-and-down rotation. The drive lever 214 has a drive groove 2141 that opens toward the side of the vertical adjustment component 22.

[0044] Reference Figure 3 and Figure 5 The vertical adjustment assembly 22 includes multiple vertical blades 221 arranged vertically side-by-side and rotatably mounted on the air outlet housing 1, and a second synchronous link 222 connecting the bottoms of the multiple vertical blades 221. In this embodiment, there are five vertical blades 221. One of the five vertical blades 221, located in the middle position, has a drive rod 223 on the side facing the horizontal adjustment assembly 21. The drive rod 223 is arranged in the drive groove 2141 of the drive lever 214. When the adjustment knob 213 moves horizontally, the sliding part 2132 can drive the drive lever 214 to slide horizontally synchronously. Since the drive rod 223 is arranged in the drive groove 2141 and the vertical blades 221 are rotatably mounted on the air outlet housing 1, the drive rod 223 slides in the drive groove 2141, thereby driving the vertical blades 221 to rotate. The second synchronous link 222 can drive the other four vertical blades 221 to rotate synchronously.

[0045] Reference Figure 1 and Figure 2 The air outlet housing 1 is also provided with a diffuser ring 14 at the air outlet 12. The opening of the diffuser ring 14 gradually increases from the direction of the air inlet 11 toward the air outlet 12. When the horizontal blades 211 and the vertical blades 221 rotate, the output air can be input into the car cabin along the side wall of the diffuser ring 14, so that the output air is more uniform.

[0046] Reference Figure 6 and Figure 7The light-emitting mechanism 3 includes a light-transmitting plate 31 installed in the air outlet housing 1 near the air outlet 12, a light guide strip 32 wrapped around the back of the light-transmitting plate 31, and a light-emitting part 33 installed in the air outlet housing 1. The light-emitting part 33 has an insertion hole 331 and symmetrically provided snap-fit ​​holes 332 on the side wall of the insertion hole 331. The end side wall of the light guide strip 32 is symmetrically provided with snap-fit ​​protrusions 321. When connecting the light-emitting part 33 and the light guide strip 32, the end of the light guide strip 32 is inserted into the insertion hole 331, so that the snap-fit ​​protrusions 321 are engaged in the snap-fit ​​holes 332, thereby achieving the connection between the light-emitting part 33 and the light guide strip 32. The light-emitting part 33 can emit light into the light guide strip 32, causing the light guide strip 32 to light up.

[0047] Reference Figure 6 and Figure 8 The air outlet housing 1 has multiple mounting clips 15 arranged circumferentially on the side near the air outlet 12, and the mounting clips 15 have mounting slots 151 on the side facing the light-transmitting plate 31. When installing the light guide strip 32, the light guide strip 32 is placed in the mounting slot 151, and then the light guide strip 32 is covered by the light-transmitting plate 31 to fix the light guide strip 32.

[0048] Reference Figure 2 and Figure 6 The opening of the light-transmitting plate 31 gradually increases in size from the air inlet 11 towards the air outlet 12. A primer is sprayed onto the side of the light-transmitting plate 31 facing the light guide strip 32. Then, a ring of light-transmitting windows 311 is circumferentially engraved using laser engraving in the area directly opposite the light guide strip 32, ensuring that the light-transmitting windows 311 are directly opposite the light guide strip 32. The primer-coated area in the light-transmitting plate 31 blocks the light from the light guide strip 32, allowing the light to escape only through the light-transmitting windows 311.

[0049] Reference Figure 6 and Figure 9 The light-transmitting plate 31 and the air outlet housing 1 are connected by a snap-fit ​​structure. The snap-fit ​​structure includes multiple snap-fit ​​pieces 312 circumferentially disposed on the back side of the light-transmitting plate 31 and snap-fit ​​components 16 circumferentially disposed on the outer side wall of the air outlet housing 1 and arranged in a one-to-one correspondence with the multiple snap-fit ​​pieces 312.

[0050] Reference Figure 6 and Figure 10 The snap-fit ​​tab 312 includes a snap-fit ​​body 3121 connected to the light-transmitting plate 31, a connecting portion 3122 connected to the snap-fit ​​body 3121, and a limiting portion 3213 connected to the connecting portion 3122. The snap-fit ​​body 3121, the connecting portion 3122, and the limiting portion 3213 are integrally formed, and the width of the connecting portion 3122 is smaller than the width of the limiting portion 3213.

[0051] Reference Figure 6 and Figure 10The latching assembly 16 includes a latching seat 161 disposed on the outer wall of the air outlet housing 1 facing the light-transmitting plate 31, and a limiting protrusion 162 disposed on the outer wall of the air outlet housing 1 away from the light-transmitting plate 31. The latching seat 161 has a latching groove 1611 for the latching tab 312 to pass through. The limiting protrusion 162 is generally L-shaped, and there are two limiting protrusions 162, which are arranged opposite to each other. The limiting protrusion 162 has an abutment surface 1621 on the side facing away from the light-transmitting plate 31, and a guide surface 1622 at the end facing away from the outer wall of the air outlet housing 1. When installing the light-transmitting plate 31, the snap-fit ​​piece 312 passes through the snap-fit ​​groove 1611 of the snap-fit ​​seat 161. When the end of the limiting part 3213 facing away from the light-transmitting plate 31 abuts against the guide surface 1622 of the limiting protrusion 162, the guide surface 1622 can push the limiting part 3213 towards the direction away from the outer wall of the air outlet housing 1, and continue to push the light-transmitting plate 31, so that the side of the limiting part 3213 facing the light-transmitting plate 31 can abut against the abutment surface 1621 of the limiting protrusion 162. The connecting part 3122 is arranged between the two limiting protrusions 162.

[0052] Reference Figure 6 and Figure 10 The snap-fit ​​piece 312 has a reinforcing rib 3124 on one end face facing away from the outer wall of the air outlet housing 1. The reinforcing rib 3124 extends from the snap-fit ​​body 3121 to the connecting part 3122, so that when the limiting part 3213 is pushed up by the limiting protrusion 162, and after the light-transmitting plate 31 is further pushed, the limiting part 3213 can quickly return to its original position and abut against the outer wall of the air outlet housing 1. Among them, the bottom end of the limiting part 3213 away from the connecting part 3122 is also provided with an inclined surface 32131, so that when the limiting part 3213 abuts against the guide surface 1622 of the limiting protrusion 162, the cooperation between the inclined surface 32131 and the guide surface 1622 makes it easier for the limiting part 3213 to be pushed up.

[0053] Reference Figure 6 and Figure 10 To ensure accurate engagement between the snap-fit ​​piece 312 and the snap-fit ​​assembly 16 during installation of the light-transmitting panel 31, multiple positioning pieces 313 are circumferentially spaced on the back side of the light-transmitting panel 31, and positioning grooves 17 are circumferentially arranged corresponding to the positioning pieces 313. This allows the positioning pieces 313 to be inserted into the positioning grooves 17 during installation of the light-transmitting panel 31, thereby achieving positioning of the light-transmitting panel 31.

[0054] Combination Figures 1 to 10The implementation principle of a car luminous air vent in this application embodiment is as follows: a light-emitting mechanism 3 is provided at the air vent housing 1 near the air vent 12. The light-emitting part 33 can emit light to the light guide strip 32, making the light guide strip 32 bright. The back side of the light-transmitting plate 31 is coated with a primer and a ring of light-transmitting windows 311 is engraved by laser engraving process, so that the light emitted by the light guide strip 32 can only be transmitted through the light-transmitting windows 311. Since the opening of the light-transmitting plate 31 gradually increases from the air inlet 11 to the air outlet 12, the light from the light guide strip 32 is not likely to directly shine into the driver's eyes, thereby reducing the probability of glare.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
