Description

Technical Field

[0001] This invention belongs to the field of automotive air vent technology, and relates to an air vent knob and blade structure assembly. Background Technology

[0002] Car air conditioning vents are interior components, typically located inside the car or diagonally above the driver's seat. When the interior temperature needs adjustment, the air conditioning is turned on for cooling or heating, and air flows from these vents, providing comfort. During use, the airflow direction and volume may need adjustment depending on the user and environment. The air conditioning vent control knobs control the direction of the airflow. Specifically, moving the knob up and down adjusts the angle of the outer blades, thus controlling the vertical airflow, while moving it left and right adjusts the angle of the inner blades, thus controlling the horizontal airflow.

[0003] like Figure 10 As shown, in the existing air outlet, the knob passes through the blade and is connected to the knob base by a snap-fit ​​connection. In the pull-out force test of the air outlet, one side of the knob is subjected to an outward pulling force, which causes the snap-fit ​​on the knob to deform. Because the deformation direction of the snap-fit ​​is the same as or close to the disengagement direction of the snap-fit, the snap-fit ​​is easy to disengage, causing the knob and blade structure of the air outlet to fail the pull-out force test. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a knob and blade structure assembly for an air outlet.

[0005] The objective of this invention can be achieved through the following technical solution: a toggle switch and blade structure assembly for an air outlet, comprising:

[0006] blade;

[0007] A toggle assembly, comprising a toggle block and a toggle base, wherein the toggle block is provided with a buckle and the toggle base is provided with a slot, the buckle engaging with the slot to connect the toggle block and the toggle base, and the toggle assembly being mounted on the blade through the connection between the toggle block and the toggle base.

[0008] The buckle can deform in the release direction to separate from the slot. When the toggle block is subjected to a pulling force, the buckle tends to move in the deformation direction due to the pulling force. The release direction is not consistent with the deformation direction.

[0009] Preferably, the tripping direction is perpendicular to the deformation direction.

[0010] Preferably, the end of the buckle has a buckle head, the buckle groove has a buckle seat, the buckle head has a first inclined surface, and the buckle seat has a second inclined surface corresponding to the first inclined surface. When the buckle head is inserted into the buckle groove, the first inclined surface and the second inclined surface abut against each other and push the buckle to deform along the buckling direction. After the buckle is installed in place, it springs back and the buckle head locks into the buckle seat.

[0011] Preferably, the first inclined surface is disposed on one side of the card head perpendicular to the release direction.

[0012] Preferably, the buckle is configured as a double-sided buckle structure, the buckle head has two buckle blocks located on its two sides respectively, the buckle groove has two buckle seats, and when the buckle is engaged with the buckle groove, the end of the buckle is located between the two buckle seats and the two buckle blocks respectively engage the two buckle seats.

[0013] Preferably, the gap between the two card holders in the card slot is smaller than the width of the card head.

[0014] Preferably, the blade has a mounting groove that extends through the front and rear of the blade, the toggle block and the toggle base are located at the front and rear of the blade respectively, the toggle block has a connecting part that is inserted into the mounting groove, and the buckle is disposed on the connecting part.

[0015] Preferably, the toggle block has a receiving groove, the blade is located in the receiving groove and passes through the two side openings of the receiving groove, and the toggle base is located behind the blade and seals the rear opening of the receiving groove.

[0016] Preferably, the toggle block is provided with a positioning rib, the toggle base is provided with a positioning hole, and the positioning rib is connected to the positioning hole.

[0017] Preferably, the blade has hinge shafts at both ends, the toggle assembly can rotate the blade about the hinge shafts, the toggle assembly can be slidably connected to the blade, and the toggle assembly can slide along the length direction of the blade.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By redesigning the release direction of the buckle so that it is not the same as the deformation direction, the buckle will not come out due to deformation when the toggle block is subjected to pulling force, thus ensuring the reliability of the connection between the toggle block and the blade.

[0020] 2. After the latch head passes the latch seat, the latch springs back to its original position and locks onto the latch seat to fix the toggle block and the toggle base together. This means that if the latch needs to be separated from the latch slot, the latch must be deformed in the release direction to separate the latch head from the latch seat. The latch cannot achieve the purpose of separation and release when it is deformed in other directions.

[0021] 3. The two sides of the card head (i.e. the card block part) and the two card seats achieve the effect of double-sided card engagement. When the toggle block is subjected to pulling force, the double-sided card structure can better prevent the buckle from falling out of the card slot.

[0022] 4. When the buckle tends to move in the direction of deformation, the locking block tends to move towards the locking seat, making the two more tightly locked together. Since the locking head is larger than the gap between the two locking seats, it can prevent the buckle from coming out.

[0023] 5. During assembly, the toggle block is brought close to the toggle base. When the two are brought together to a certain position, the positioning rib is inserted into the positioning hole, thereby positioning the toggle block and the toggle base. At this time, each buckle is aligned with its respective slot, and then each buckle can be inserted into its respective slot to complete the connection. This facilitates assembly.

Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1-9 As shown, an air outlet toggle and blade structure assembly includes: a blade 100 and a toggle assembly. The toggle assembly includes a toggle block 200 and a toggle base 400. The toggle block 200 is provided with a buckle 300, and the toggle base 400 is provided with a slot 500. The buckle 300 engages with the slot 500 to connect the toggle block 200 and the toggle base 400. The toggle assembly is installed on the blade 100 through the connection between the toggle block 200 and the toggle base 400. The buckle 300 can deform in the release direction to separate from the slot 500. When the toggle block 200 is subjected to a pulling force, the buckle 300 tends to move in the deformation direction due to the pulling force. The release direction is inconsistent with the deformation direction.

[0037] Since the air outlet requires the left and right movement of the toggle assembly to achieve the purpose of lateral airflow, the toggle assembly needs to be slidably connected to the blade 100. The toggle assembly consists of a toggle block 200 and a toggle base 400. After the toggle block 200 and the toggle base 400 are engaged, they hold the blade 100, thereby allowing the toggle assembly to be slidably connected to the blade 100. Specifically, the toggle block 200 is at least in contact with the front of the blade 100, and the toggle base 400 is in contact with the rear of the blade 100. When the toggle block 200 and the toggle base 400 are engaged, the blade 100 is clamped from both the front and rear sides, thus achieving assembly.

[0038] Since the toggle block 200 needs to be engaged with the slot 500 of the toggle base 400 via the snap fastener 300, the snap fastener 300 is designed as an elastic structure. The direction of elastic deformation of the snap fastener 300 during assembly is the release direction. After the toggle block 200 and the toggle base 400 are assembled, the snap fastener 300 springs back to its original position and engages with the slot 500. The deformation direction is the direction of the movement tendency of the snap fastener 300 when the toggle block 200 is subjected to force. Generally speaking, the deformation direction is opposite to the direction of the pull force on the toggle block 200.

[0039] When the toggle block 200 is subjected to a pulling force, the latch 300 tends to deform due to the force. For example, when the pulling force on the toggle block 200 is forward, the deformation direction of the latch 300 is backward. The latch 300 can only separate from the slot 500 when it deforms in the release direction. Therefore, when the toggle block 200 is subjected to a pulling force, the latch 300 will not separate from the slot 500.

[0040] By redesigning the release direction of the buckle so that it is not the same as the deformation direction, the buckle will not come out due to deformation when the toggle block is subjected to a pulling force, thus ensuring the reliability of the connection between the toggle block and the blade.

[0041] Based on the above implementation method, the tripping direction is perpendicular to the deformation direction.

[0042] like Figure 1-9 As shown, based on the above embodiment, the end of the buckle 300 has a buckle head 310, and the buckle groove 500 has a buckle seat 510. The buckle head 310 has a first inclined surface 311, and the buckle seat 510 has a second inclined surface 511 corresponding to the first inclined surface 311. When the buckle head 310 is inserted into the buckle groove 500, the first inclined surface 311 and the second inclined surface 511 abut against each other and push the buckle 300 to deform along the first direction. After the buckle 300 is installed in place, it springs back and the buckle head 310 latches the buckle seat 510.

[0043] During assembly of the toggle block 200 and the toggle base 400, the locking seat 510 pushes the latch 300 to move in the release direction, causing the latch head 310 to pass over the locking seat 510. After the latch head 310 passes over the locking seat 510, the latch 300 springs back to its original position, and the latch head 310 latches the locking seat 510 to fix the toggle block 200 and the toggle base 400 together. This means that if the latch 300 needs to be separated from the latch slot 500, the latch 300 must be deformed in the release direction to separate the latch head 310 from the locking seat 510. The latch 300 cannot achieve the purpose of separation and release when deformed in other directions.

[0044] Based on the above embodiment, a first inclined surface 311 is provided on one side of the latch 310 perpendicular to the release direction. Since the first inclined surface 311 is located on this side, the latch 300 can deform along the release direction during assembly.

[0045] like Figure 2-9 As shown, based on the above embodiment, the buckle 300 is configured as a double-sided buckle structure, the buckle head 310 has two buckle blocks 312 located on its two sides respectively, and the buckle groove 500 has two buckle seats 510. When the buckle 300 is engaged with the buckle groove 500, the end of the buckle 300 is located between the two buckle seats 510 and the two buckle blocks 312 respectively fasten the two buckle seats 510.

[0046] It should be noted that the double-sided locking structure of the buckle 300 refers to the fact that both sides of the buckle head 310 have locking blocks 312. Therefore, the two sides of the buckle head 310 (i.e., the locking blocks 312) and the two locking seats achieve the effect of double-sided locking. When the toggle block 200 is subjected to pulling force, the double-sided locking structure can better prevent the buckle 300 from coming out of the slot 500.

[0047] like Figure 2-9 As shown, based on the above implementation method, the gap between the two card holders 510 in the card slot 500 is smaller than the width of the card head 310.

[0048] like Figure 10 As shown, in the existing structure, because the slot must reserve space for the buckle to deform, the buckle is generally designed as a single-sided buckle structure, which makes the buckle particularly easy to come out of the slot.

[0049] like Figure 2-9 As shown, in this embodiment, the latch 300 can pass through the gap between the two latch seats 510 and the two latching blocks 312 on the latch head 310 can lock the two latch seats 510. Since the latch head 310 is larger than the gap between the two latch seats 510, when the toggle block 200 is subjected to a pulling force, the latch head 310 cannot pass through the gap between the two latch seats 510, and the latching blocks 312 and the latch seats 510 are more tightly pressed together, so the latch 300 can be prevented from coming off.

[0050] Example 1:

[0051] like Figure 1-5 As shown, the blade 100 has a mounting groove 110 that extends through the front and rear of the blade 100. The toggle block 200 and the toggle base 400 are located at the front and rear of the blade 100, respectively. The toggle block 200 has a connecting part 210 that is inserted into the mounting groove 110. The buckle 300 is provided on the connecting part 210.

[0052] In this embodiment, the connecting part 210 of the toggle block 200 is inserted into the mounting groove 110 of the blade 100, and the connecting part 210 is engaged with the toggle base 400 by the snap 300, so that the toggle block 200 is mounted on the blade 100; and the connecting part 210 can slide in the mounting groove 110 so that the toggle block 200 is slidably connected to the blade 100.

[0053] Example 2:

[0054] like Figure 6-9 As shown, the toggle block 200 has a receiving groove 220, the blade 100 is located in the receiving groove 220 and passes through the two side openings of the receiving groove 220, and the toggle base 400 is located behind the blade 100 and seals the rear opening of the receiving groove 220.

[0055] In this embodiment, the toggle block 200 wraps around the blade 100 through the receiving groove 220, and the toggle base 400 engages with the toggle block 200 to seal the rear opening of the receiving groove 220, so that the toggle block 200 and the blade 100 are slidably connected.

[0056] like Figure 1-9 As shown, based on the above embodiment, the toggle block 200 is provided with a positioning rib 230, and the toggle base 400 is provided with a positioning hole 410, with the positioning rib 230 connected to the positioning hole 410.

[0057] During assembly, the toggle block 200 is brought close to the toggle base 400. When the two are brought together to a certain position, the positioning rib 230 is inserted into the positioning hole 410, thereby positioning the toggle block 200 and the toggle base 400. At this time, each buckle 300 is aligned with each slot 500, and then each buckle 300 can be inserted into each slot 500 to complete the connection, which can facilitate assembly.

[0058] like Figure 1-4 As shown, based on the above embodiment, the blade 100 has hinge shafts 120 at both ends. The toggle assembly can rotate the blade 100 around the hinge shafts 120. The toggle assembly can be slidably connected to the blade 100 and can slide along the length direction of the blade 100.

[0059] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0060] Furthermore, in this invention, descriptions involving "first," "second," "a," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0061] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction between two elements, unless otherwise explicitly limited.

[0062] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
