Technical Field
[0001] This utility model relates to the field of in-vehicle air purification, and in particular to an in-vehicle air purification device. Background Technology
[0002] Car air purifiers, also known as vehicle air purifiers or car air purifiers, are devices specifically designed to purify the air inside a car, removing PM2.5, toxic and harmful gases (formaldehyde, benzene compounds, TVOC, etc.), odors, bacteria, viruses, and other pollutants.
[0003] In practical use, to meet the needs of different users and the characteristics of the interior space layout, car air purifiers usually have a variety of installation locations to choose from. Common installation locations include the center of the dashboard, the center armrest, the platform below the rear windshield, the top of the rear seat armrest, and the center console. When the car air purifier is installed on the center armrest, elastic straps are generally used to fix it to increase its stability. Similarly, elastic straps can also be used to fix the car air purifier to the back of the front seats, providing users with more installation options.
[0004] Because elastic straps typically have a certain width, when used to secure a car air purifier, its overall structure becomes irregular. This makes it inconvenient to place the air purifier in the center of the dashboard or above the center console, where the dashboard and center console are usually flat and have limited space. The width of the elastic straps occupies extra space, preventing the air purifier from being placed stably. This limits the range of placement of the air purifier within the vehicle, preventing users from flexibly choosing the installation location according to their needs and the actual environment inside the car. Consequently, it affects the convenience and practicality of using the air purifier. Therefore, this invention provides a car interior air purification device to meet these needs. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an in-vehicle air purification device. By setting a fixing component, users can more flexibly choose the installation position of the in-vehicle air purifier according to their own usage needs and the actual space layout of the vehicle. The above setting can solve the problem that the fixing range of the in-vehicle air purifier in the vehicle is limited due to the elastic strap fixing of the existing in-vehicle air purifier.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] An in-vehicle air purification device includes an in-vehicle air purifier, a support base at the bottom of the in-vehicle air purifier, a support frame fixed to the bottom of the inner wall of the support base, the top of the support frame abutting against the bottom of the in-vehicle air purifier, limiting posts at each of the four corners of the support base, each of the four limiting posts having a weakening groove on its surface, and the four limiting posts abutting against the top four corners of the in-vehicle air purifier respectively, and anti-slip pads fixed to the bottom four corners of the support base; and a fixing assembly for assisting in fixing the in-vehicle air purifier inside the vehicle, the fixing assembly being connected to the support frame.
[0008] Optionally, the fixing assembly includes a clamping plate that rotates between the inner walls of the support frame. Two clamping plates are symmetrically arranged, and a connecting shaft rotates within each of the two clamping plates. A torsion spring is sleeved on the surface of each connecting shaft, and the two ends of the torsion spring abut against the support frame and the clamping plate, respectively.
[0009] Optionally, the clamping plate has an arc-shaped portion on the side away from the connecting shaft, a protrusion on one side of the arc-shaped portion, and an abutment portion on one side of the protrusion.
[0010] Optionally, one side of the abutment portion is wavy.
[0011] Optionally, the support base has a slot at the bottom, a clip is engaged in the slot, and a plug is fixed at the top of the clip. The surface of the plug abuts against the side of the vehicle air purifier.
[0012] Optionally, the top of the support is provided with a socket, the plug is inserted into the socket, and the plug passes through the socket and abuts against the side of the vehicle air purifier.
[0013] Optionally, the insert surface is provided with a protruding button, which is tangent to the projection of the side cross section of the vehicle air purifier.
[0014] Optionally, an elastic rope is fixed inside the clip frame, and the elastic rope is located inside the clip groove.

[0018] In the above solution, by setting fixed components, users can more flexibly choose the installation location of the car air purifier according to their own usage needs and the actual space layout inside the car, which is conducive to giving full play to the purification effect of the car air purifier and creating a healthier and more comfortable in-car environment for users.
[0019] By setting up a support base, support frame, limiting post, and anti-slip pad, a stable foundation is provided for the car air purifier, enhancing the stability of its placement. It also protects the car air purifier and reduces damage from external impacts.
[0020] By incorporating clamps, connecting shafts, and torsion springs, the car air purifier can be flexibly positioned according to the actual space inside the vehicle and the user's needs, satisfying diverse installation requirements. Users can easily switch between different mounting methods by simply rotating the clamps, without needing complicated tools or tedious installation steps, effectively improving convenience and efficiency.

[0038] like Figures 1 to 7As shown, an embodiment of this utility model provides an in-vehicle air purification device, including an in-vehicle air purifier 1. The working principle of the in-vehicle air purifier 1 is as follows: a micro fan inside the in-vehicle air purifier 1 circulates the air inside the vehicle. Polluted air passes through the PM2.5 filter and activated carbon filter inside the machine, filtering or adsorbing various pollutants. Then, the air passes through a negative ion generator installed at the air outlet, where a high voltage is generated to produce a DC negative high voltage, continuously ionizing the air and generating a large number of negative ions. These negative ions are then sent out by the micro fan, forming a negative ion airflow, thus achieving the purpose of cleaning the air. This part is disclosed as prior art and will not be described in detail here. The bottom of the in-vehicle air purifier 1 is provided with a support 2. A support bracket 6 is fixed to the bottom of the inner wall of the support 2. The top of the support bracket 6 abuts against the bottom of the car air purifier 1. Limiting posts 3 are provided at each of the four corners of the support 2. Each of the four limiting posts 3 has a weakening groove 4 on its surface. The four limiting posts 3 abut against the top four corners of the car air purifier 1. Anti-slip pads 5 are fixed to the four corners of the bottom of the support 2. In use, the car air purifier 1 is placed on the support 2. The top of the support bracket 6 fixed to the bottom of the inner wall of the support 2 abuts against the bottom of the car air purifier 1, providing a stable base support platform for the car air purifier 1, allowing it to be placed stably on the support 2. After the car air purifier 1 is placed on the support 2, the limiting posts 3 open from the four corners of the support 2. The corner brackets limit the movement of the in-vehicle air purifier 1, preventing displacement. Simultaneously, the weakening grooves 4 on the surface of the limiting post 3 provide flexibility, allowing for deformation under external force or pressure from the air purifier 1 during placement. This better conforms to the shape of the air purifier 1, providing more precise limiting. Combined with the limiting post 3, this reduces damage to the air purifier 1 from external impacts. The anti-slip pads 5 fixed at the four corners of the support 2 increase friction between the support 2 and the surface it's placed on, such as the center console or center armrest. During vehicle operation, the anti-slip pads 5 help maintain the stability of the support 2 and the surface. The interior features a stable placement of the in-vehicle air purifier 1; a fixing component, which assists in fixing the in-vehicle air purifier 1 inside the car. The fixing component is connected to the support bracket 6. The fixing component functions similarly to an elastic strap to stably fix the in-vehicle air purifier 1 to the center armrest or the back of the front seats, and can also meet the need to stably place the in-vehicle air purifier 1 on the top of the center console or the platform under the rear windshield. This allows users to more flexibly choose the installation position of the in-vehicle air purifier 1 according to their own usage needs and the actual space layout inside the car, which is conducive to giving full play to the purification effect of the in-vehicle air purifier 1 and creating a healthier and more comfortable in-vehicle environment for users.
[0039] It should be noted that the support 2, the support frame 6, and the four limiting posts 3 are integrally molded and can be completed through one-time injection molding or die casting processes, which effectively simplifies the production process. This not only reduces the number of steps and time in the production process and lowers the production cost, but also improves the production efficiency. The support 2 and the support frame 6 together provide support for the vehicle air purifier 1, while the four limiting posts 3 can also limit the vertical sway of the vehicle air purifier 1 to a certain extent, thus providing effective protection for the vehicle air purifier 1.
[0040] As one implementation method in this embodiment, such as Figures 1 to 3As shown, the fixing assembly includes two clamping plates 7 that rotate between the inner walls of the support frame 6. Each clamping plate 7 has a connecting shaft 8 rotating within it. A torsion spring 9 is fitted onto the surface of each connecting shaft 8. The two ends of the torsion spring 9 abut against the support frame 6 and the clamping plate 7, respectively. An arc-shaped portion 10 is provided on the side of the clamping plate 7 away from the connecting shaft 8. A protrusion 11 is provided on one side of the arc-shaped portion 10, and an abutment portion 12 is provided on one side of the protrusion 11. When it is necessary to fix the vehicle air purifier 1 to the center armrest box, the two symmetrical clamping plates 7 are rotated open around the connecting shaft 8 to overcome the elastic force of the torsion spring 9. Since the two ends of the torsion spring 9 abut against the support frame 6 and the clamping plate 7, respectively... The support bracket 6 and the clamping plate 7 abut against each other. During the opening process, the torsion spring 9 undergoes elastic deformation. After opening, the protrusion 11 of the clamping plate 7 engages with both sides of the center armrest box lid, while the abutting part 12 abuts against both sides of the center armrest box body. Under the elastic force of the torsion spring 9, the clamping plate 7 tightly clamps the center armrest box, thereby firmly fixing the support 2 and the in-vehicle air purifier 1 fixed inside it to the center armrest box. When it is necessary to fix the in-vehicle air purifier 1 in other positions, such as above the center console or under the rear windshield platform, the clamping plate 7 is completely folded into the support bracket 6 under the elastic force of the torsion spring 9. At this time, the abutting part... 12 abuts against the bottom of the car air purifier 1, providing auxiliary support. Together with the support frame 6, it supports the car air purifier 1, further ensuring the stability of the car air purifier 1. When the clamp 7 is opened by external force, the arc-shaped part 10 can deform to a certain extent, allowing the clamp 7 to better fit the center armrest box, further ensuring the clamping stability of the clamp 7. This allows the car air purifier 1 to flexibly choose its fixing position according to the actual space in the car and the user's needs. It can be conveniently fixed to the center armrest box, making full use of the interior space, or the clamp 7 can be folded down to allow the car air purifier to be placed in a more secure position. The air purifier 1 is stably placed on the platform above the center console and below the rear windshield, meeting the diverse installation needs of users. Users can switch the fixing method simply by rotating the clamp 7, without the need for complicated tools or cumbersome installation steps, effectively improving the convenience and efficiency of use. The protrusion 11 engages with both sides of the center armrest box cover to prevent the clamp 7 from sliding, and the abutment part 12 abuts against both sides of the center armrest box body, further enhancing the clamping stability of the clamp 7. The two work together to ensure that the vehicle air purifier 1 is firmly fixed on the center armrest box.
[0041] In this embodiment, as Figure 2 and Figure 3As shown, one side of the abutment portion 12 is wavy. The wavy abutment portion 12 increases the friction between the clamping plate 7 and the sides of the center armrest box or the bottom of the vehicle air purifier 1, thereby effectively preventing the clamping plate 7 from sliding and further improving the stability of the clamping plate 7. When providing auxiliary support, it can also ensure that the abutment portion 12 is in close contact with the bottom of the vehicle air purifier 1, further ensuring the stability of the vehicle air purifier 1. At the same time, the wavy abutment portion 12 can also play a certain role in buffering and shock absorption, absorbing some of the vibration energy generated by the vehicle's movement and reducing the impact of external forces on the vehicle air purifier 1.
[0042] In this embodiment, as Figures 3 to 7 As shown, the support 2 has two symmetrical slots 13 at its bottom, each slot 13 housing a locking bracket 15. Each locking bracket 15 has a fixed insert block 16 at its top, with the surface of the insert block 16 abutting against the side of the vehicle air purifier 1. The support 2 has a socket 14 at its top, with the insert block 16 engaging with the socket 14. The insert block 16 passes through the socket 14 and abuts against the side of the vehicle air purifier 1. The surface of the insert block 16 has a protruding button 17 tangent to the projection of the side cross-section of the vehicle air purifier 1. In use, the locking bracket 15 is first placed in the slot 13 at the bottom of the support 2, and then... The snap-fit between the 13 and the snap-fit bracket 15 initially fixes the snap-fit bracket 15 to the bottom of the support 2. The insert 16 on the top of the snap-fit bracket 15 is aligned with the insertion hole 14 on the top of the support 2, and the insert 16 is inserted into the insertion hole 14. The protrusion 17 on the surface of the insert 16 deforms and is inserted into the insertion hole 14 along with the insert 16. When the insert 16 is fully inserted into the insertion hole 14, the protrusion 17 is tangent to the projection of the side section of the vehicle air purifier 1. The protrusion 17 exerts a certain squeezing effect on the side of the vehicle air purifier 1, further enhancing the connection stability between the vehicle air purifier 1 and the support 2.
[0043] In this embodiment, as Figures 3 to 7As shown, an elastic cord 20 is fixed inside the snap-fit bracket 15. The elastic cord 20 is located in the snap-fit groove 13, and a connecting pin 19 is fixed at both ends of the elastic cord 20. Threaded holes 18 are opened inside the snap-fit bracket 15, and the connecting pins 19 are threadedly connected to the threaded holes 18. As mentioned above, there are two snap-fit brackets 15 symmetrically arranged, therefore, there are also two sets of elastic cords 20 symmetrically arranged. This facilitates the suspension and fixation of the support seat 2 and its internal vehicle air purifier 1 to the back of the front seat through the two sets of symmetrical elastic cords 20. The symmetrical arrangement of the elastic cords 20 can share the force acting on the vehicle air purifier 1, making the vehicle... The air purifier 1 can always remain in a relatively fixed position. At the same time, the suspension method of the two sets of elastic ropes 20 can be adapted to the shape of the front seat back of different car models, thereby enhancing the applicability and practicality of the car air purifier 1. The threaded connection method of the connecting pin 19 and the threaded hole 18 allows users to easily remove the damaged or aged elastic rope 20 and replace it with a new one. The replacement does not require complicated tools or professional repair skills. It can be completed with a simple twisting operation, which improves the convenience of maintenance and repair and reduces the cost of use.
[0044] In this embodiment, as Figure 6 As shown, the elastic cord 20 is spiral-shaped. The spiral elastic cord 20 can have a longer unfolded length in a limited space. When the support seat 2 and the in-vehicle air purifier 1 inside it need to be suspended and fixed on the back of the front seat, the longer unfolded length can provide a greater suspension range and flexibility, making it convenient for users to adjust according to the position and space of the seat back, ensuring that a suitable suspension point can be found and a stable and reliable fixation can be achieved. When the elastic cord 20 is not in use, the spiral structure allows the elastic cord 20 to naturally retract into the slot 13, which not only prevents the elastic cord 20 from hanging down randomly and affecting the aesthetics and riding comfort of the car, but also prevents the elastic cord 20 from getting tangled or damaged with other items.
[0045] The working principle of the technical solution provided by this utility model is as follows:
[0046] When in use, place the car air purifier 1 on the support bracket 6 inside the support 2. The limiting posts 3 at the four corners of the support 2 limit the car air purifier 1 from the four corners. The weakening grooves 4 on the surface of the limiting posts 3 deform when the car air purifier 1 is placed, so that the limiting posts 3 better fit the shape of the four corners of the car air purifier 1. This can not only keep the car air purifier 1 stable, but also protect the car air purifier 1.
[0047] When the car air purifier 1 is fixed to the center armrest box, the two symmetrical clamps 7 are rotated and opened around the connecting shaft 8 to overcome the elastic force of the torsion spring 9. The torsion spring 9 undergoes elastic deformation. After opening, the protrusions 11 of the clamps 7 engage with the two sides of the center armrest box cover, and the abutment parts 12 abut against the two sides of the box body. Under the action of the torsion spring 9, the center armrest box is clamped, fixing the support 2 and the car air purifier 1. The arc-shaped part 10 deforms when the clamps 7 are opened by external force, so that the clamps 7 fit the center armrest box better and ensure clamping stability. The wavy abutment part 12 increases the friction between the clamps 7 and the center armrest box, ensuring the stability of the car air purifier 1. The snap-fit bracket 15 is placed in the bottom slot 13 of the support 2 for initial fixation. The insert block 16 on the top of the snap-fit bracket 15 is aligned with the insertion hole 14 on the top of the support 2 and inserted. The protrusions on the surface of the insert block 16 Button 17 is inserted into socket 14 along with plug 16. After insertion, the protruding button 17 is tangent to the side cross-sectional projection of the vehicle air purifier 1, which exerts a squeezing effect on the side of the vehicle air purifier 1, further enhancing the connection stability between the vehicle air purifier 1 and the support 2. When the vehicle air purifier 1 is fixed on the top of the center console or the platform under the rear windshield, the clamp 7 is removed from the center armrest box. Under the elastic force of the torsion spring 9, the clamp 7 is completely folded into the support 6. At this time, the abutting part 12 abuts against the bottom of the vehicle air purifier 1, which plays an auxiliary supporting role. Together with the support 6, it ensures the stability of the vehicle air purifier 1. The anti-slip pads 5 at the four corners of the bottom of the support 2 contact the placement surface, such as the top of the center console or the platform under the rear windshield, to increase friction and further ensure the stable placement of the support 2 and the vehicle air purifier 1 inside.
[0048] When the car air purifier 1 is suspended on the back of the front seat, two sets of elastic cords 20 symmetrically arranged on the inner side of the clip bracket 15 are used. The connecting pins 19 at both ends of the elastic cords 20 are threaded into the threaded holes 18 on the inner side of the clip bracket 15, which facilitates the replacement of damaged or aged elastic cords 20. The spiral elastic cords 20 unfold, allowing for a longer unfolded length in a limited space, providing a greater suspension range and flexibility. This allows users to adjust the suspension according to the position and space of the seat back and find a suitable suspension point for stable fixation. When not in use, the spiral structure allows the elastic cords 20 to naturally retract into the slots 13, avoiding affecting the aesthetics and ride comfort of the car interior, and preventing entanglement or damage with other items.
[0049] The different fixing methods of the above-mentioned car air purifier 1 allow users to choose the installation location of the car air purifier 1 more flexibly according to their own usage needs and the actual space layout of the car, which is conducive to giving full play to the purification effect of the car air purifier 1, and effectively improving flexibility and practicality.
