Description
Technical Field
[0001] This utility model relates to a vehicle insect net assembly, and more specifically to a three-layer multifunctional vehicle insect net assembly that is detachably connected to the trunk door of a vehicle and can selectively use a transparent windshield, an insect net, and a sunshade. Background Technology
[0002] Recently, there has been a growing trend of using SUVs or RVs for camping, as well as for overnight stays and leisure activities, leading to an increasing number of people opening their vehicle's tailgate to expand the use of external space. As this in-vehicle culture spreads, the need to protect interior privacy from external influences while the tailgate is open is becoming increasingly prominent.
[0003] Traditional car insect nets only provide basic insect protection against insects or mosquitoes. These traditional insect nets have limitations in dealing with weather changes such as wind or rain. That is, insect nets alone cannot block strong winds or small amounts of rain, allowing moisture or rainwater to enter the car when the weather changes.
[0004] Furthermore, traditional car insect nets completely fail to protect privacy. Because of their mesh structure, the interior of the vehicle is completely visible from the outside, limiting privacy at campsites or parking lots. This is especially problematic at night when the car lights are on, as the interior is clearly visible from the outside.
[0005] In addition, traditional car insect nets use magnets to attach to the edge of the vehicle at the trunk opening, but the bonding strength is weak and they are prone to separation due to wind or vibration.

[0020] The present invention will now be described in detail with reference to preferred embodiments and accompanying drawings, but the same reference numerals in the drawings shall refer to the same constituent elements.
[0021] In the detailed description or claims of a utility model, when one constituent element "includes" another constituent element, it should not be construed as consisting solely of that constituent element unless specifically stated otherwise, but should be understood as potentially including other constituent elements.
[0022] Figure 1 This is a front view showing the vehicle insect screen assembly 100 of this utility model installed on the trunk door 20 of a vehicle. Figure 2 This is a perspective view showing the front structure of the vehicle insect net assembly 100. Figure 3 This is a schematic diagram showing the rear structure of the vehicle insect net assembly 100. Figure 4 This is a partially enlarged perspective view showing the connection structure of the vehicle insect net assembly 100.
[0023] As shown in the figure, the vehicle insect net assembly 100 of this utility model includes: a vehicle connector 110 that is embeddedly connected to the door panel 13 formed on the edge of the trunk door 20 when the trunk door 20 is open; a base component 120 connected to the vehicle connector 110; zipper connectors 140 and 140a connected to the base component 120 via an integral detachable zipper 130; a transparent windshield 150 and an insect net 160 connected via zipper connectors 140 and 140a; and a light-blocking curtain 170 that is detachably connected to the insect net 160 via a light-blocking curtain zipper 171.
[0024] The vehicle insect screen assembly 100 is embedded into the edge of the vehicle's trunk door 20, allowing the user to selectively use the triple screen of the insect screen 160, the transparent windshield 150, and the sunshade 170.
[0025] The vehicle insect net assembly 100, insect net 160, transparent windshield 150, and sunshade 170 of this utility model are each independently assembled and disassembled via corresponding zippers, thus having the advantage of being easy for users to operate and use as needed.
[0026] Furthermore, the vehicle insect net assembly 100 of this utility model has the advantage of being able to maintain a stable connection with the vehicle 10 even under wind or vibration after the vehicle connector 110 is embeddedly connected to the door panel 13 of the vehicle 10 and the position is constrained by the sealing strip 30.
[0027] Here, the vehicle 10 connected to the vehicle insect net assembly 100 of this utility model refers to a vehicle such as an SUV, RV, or van equipped with a trunk door 20. Figure 5b It shows along Figure 1 A cross-sectional view of the AA line structure. Figure 5a This is a cross-sectional view showing the structure of the vehicle insect screen assembly 100 connected to the trunk door 20.
[0028] As shown in the figure, an upwardly protruding insert 11 and a door panel 13 are provided at the edge of the opening of the trunk door 20 of vehicle 10. A sealing strip 30 is embedded to cover the insert 11 and the door panel 13. In this invention, the vehicle insect screen assembly 100, after separating the sealing strip 30, embeds the vehicle connector 110 into the door panel 13, and then connects the sealing strips 30 together to cover the insert 11, the door panel 13, and the vehicle connector 110 to constrain the position.
[0029] The vehicle connector 110 is the portion of the vehicle insect screen assembly 100 that is fixedly embedded into the vehicle 10. The vehicle connector 110 is configured to correspond to the external shape of the vehicle's tailgate 20. For example... Figure 4 As shown, the vehicle connector 110 is formed by an elastic component with a "U"-shaped cross-section that is embedded into the door panel 13.
[0030] The vehicle connector 110 consists of a horizontally formed insert bottom 111, insert front sidewalls 113 and insert rear sidewalls 115 formed vertically on both sides of the insert bottom 111. The insert bottom 111 is a flat plate forming the lower part of the vehicle connector 110, which contacts the end of the door panel 13 of the vehicle 10 and provides support to stably maintain the connection. The insert bottom 111 has a thickness corresponding to the thickness of the door panel 13, distributing the load and preventing deformation.
[0031] The embedded front sidewall 113 is a vertical wall structure extending upward from the front (outer side of the vehicle) of the embedded bottom 111, having a first height h1. The embedded front sidewall 113 serves to prevent the door panel 13 from disengaging forward. The embedded front sidewall 113 is stitched to the base component 120. The base component 120 is fitted to the inner wall surface of the embedded front sidewall 113 and stitched to the vehicle connector 110 along the stitch line 113a.
[0032] The recessed rear sidewall 115 is a vertical wall structure extending upward from the rear (inside the vehicle) of the recessed bottom 111, having a second height h2. An embedding space 114 for embedding the door panel 13 is formed between the recessed bottom 111, the recessed front sidewall 113, and the recessed rear sidewall 115. The shape and size of the embedding space 114 are designed to correspond to the thickness and shape of the door panel 13.
[0033] Here, in this invention, the second height h2 of the vehicle connector 110 embedded in the rear sidewall 115 is higher than the first height h1 embedded in the front sidewall 113 (h2>h1). This height difference between the rear sidewall 115 and the front sidewall 113 effectively prevents the vehicle connector 110 from detaching rearward when it is connected to the door panel 13, greatly improving the bonding force between the vehicle connector 110 and the door panel 13.
[0034] Specifically, the second height h2 embedded in the rear sidewall 115 is formed to be more than 1.25 times and less than 2.5 times the first height h1 embedded in the front sidewall 113. This is a preferred range for improving bonding strength. When the second height h2 embedded in the rear sidewall 115 is less than 1.25 times the first height h1 embedded in the front sidewall 113, the improvement in bonding strength is minimal compared to the case where the first and second heights are the same. Conversely, experimental results show that when the height difference is greater than 1.25 times, the bonding strength is improved by more than 40%, which can ensure meaningful resistance to vehicle vibration (5Hz to 15Hz range) and wind pressure (based on gusts of wind speed from 50km / h to 80km / h).
[0035] Furthermore, when the height h2 of the rear sidewall 115 exceeds 2.5 times the height h1 of the front sidewall 113, excessive insertion force is required during installation, making installation difficult for general users and drastically increasing the risk of damage to the door panel 13. Additionally, the possibility of interference when the vehicle's trunk door 20 is opened and closed increases.
[0036] More preferably, when the second height h2 embedded in the rear sidewall 115 is 1.5 times to 2.0 times the first height h1 embedded in the front sidewall 113, an optimal balance between bonding strength and ease of installation is achieved. Within this range, the bonding strength is increased by 60-95%, while installation is sufficiently easy for the average person.
[0037] Based on these experimental results, the second height h2 embedded in the rear sidewall 115 is preferably formed to be between 8 mm and 15 mm. If it is less than 8 mm, it is difficult to ensure sufficient fixing force, and if it is more than 15 mm, excessive stress will be applied to the door panel 13 during installation, which may increase the risk of damage.
[0038] The base component 120 is connected to the vehicle connector 110, and the vehicle connector 110 and zipper connectors 140 and 140a are connected by an integral detachable zipper 130. The base component 120 detachably connects the insect screen 160, the transparent wind deflector 150, and the sunshade 170 via the zipper connectors 140 and 140a, connecting the vehicle connector 110 and the other components. The base component 120 is arranged in a fibrous form with a certain area, and its lower end is sewn and fixed to the embedded front sidewall 113 of the vehicle connector 110, which is made of an elastic material such as rubber or silicone, by sewing thread.
[0039] The overall detachable zipper 130 is a zipper located between the base component 120 and the zipper connectors 140, 140a. It is formed along the edge of the base component 120 throughout the entire area and has the function of detaching and attaching the insect net 160, the transparent wind deflector 150 and the sunshade 170 to the vehicle connector 110 and the base component 120.
[0040] like Figure 5a As shown, when assembling the vehicle insect screen assembly 100 onto the door panel 13 of the vehicle 10, the user uses the overall disassembly zipper 130 to separate the zipper connectors 140 and 140a from the base component 120, only embedding the vehicle connector 110 connected to the base component 120 into the door panel 13. This is because, as Figure 2 When the vehicle insect screen assembly 100 with all the structural connection states shown is connected to the door panel 13, it is heavy and bulky, making it difficult for the user to insert it into the door panel 13.
[0041] In addition, such as Figure 7b As shown, when the vehicle insect net assembly 100 is connected to the vehicle 10, users can use the overall disassembly zipper 130 to separate the insect net 160, transparent windshield 150 and sunshade 170 to use them all when they want to feel open.
[0042] Zipper connectors 140 and 140a serve to detachably connect the transparent windbreak 150, insect net 160, and blackout curtain 170 to the base component 120. Zipper connectors 140 and 140a are formed by overlapping and connecting a front zipper connector 140 and a rear zipper connector 140a. Figure 4 As shown, the lower ends of the front zipper connector 140 and the rear zipper connector 140a are sewn together and fixed to the overall detachable zipper 130.
[0043] Furthermore, the upper end of the front zipper connector 140 is detachably connected to the transparent wind deflector 150 via the wind deflector zipper 151, and the rear zipper connector 140a is detachably connected to the insect net 160 via the insect net zipper 161.
[0044] like Figure 2 and Figure 3 As shown, the front zipper connector 140 and the rear zipper connector 140a are overlapped at the front and rear, respectively, and are connected to the transparent wind deflector 150 and the insect screen 160. The wind deflector zipper 151 and the insect screen zipper 161 are continuously formed along the edges of the front zipper connector 140 and the rear zipper connector 140a throughout the entire area.
[0045] The transparent windshield 150 is a membrane structure of transparent or semi-transparent material disposed on the outermost side of the vehicle insect screen assembly 100. The transparent windshield 150 is made of transparent vinyl or polyurethane material to ensure visibility while blocking wind and a small amount of rain. The transparent windshield 150 is detachably connected to the front zipper connector 140 via a windshield zipper 151.
[0046] The wind deflector zipper 151 is a zipper that connects the transparent wind deflector 150 to the assembly or assembly, and is formed around the transparent wind deflector 150. When the user is not using the transparent wind deflector 150, such as... Figure 1 and Figure 6b As shown, after opening the wind deflector zipper 151 on both sides and the bottom except for the top, roll up the transparent wind deflector 150 and fix it using the front wind deflector fixing ring 180 and the front fixing block 181 provided on the upper side base component 120.
[0047] Depending on the situation, the entire wind deflector zipper 151 can be opened to separate the transparent wind deflector 150.
[0048] The insect net 160 is a mesh screen configured in the middle layer of the vehicle insect net assembly 100, performing the basic insect-proof function of blocking mosquitoes, flies, and other insects from entering. The insect net zipper 161 connects or disconnects the insect net 160 from the rear zipper connector 140a.
[0049] The sunshade 170 is a film of opaque material disposed on the innermost side (vehicle interior side) of the vehicle insect screen assembly 100, providing privacy protection. The sunshade 170 provides a sun-blocking function that prevents the interior of the vehicle from being seen from the outside.
[0050] like Figure 3 As shown, the lower part of the blackout curtain 170 is sewn and fixed to the insect net 160, and the upper part is detachably connected to the insect net 160 via a blackout curtain zipper 171. The lower part of the blackout curtain 170 is fixed to the blackout curtain receiving seam 173, and the upper part of the blackout curtain receiving seam 173 is detachably connected via a blackout curtain zipper 171.
[0051] At this time, as Figure 4 As shown, the lower region of the blackout curtain 170, which is connected to the insect net 160 via the blackout curtain receiving stitch 173, forms a blackout curtain pocket 173a between itself and the insect net 160.
[0052] like Figure 7a As shown, the blackout curtain pocket 173a serves as a storage pocket for the blackout curtain 170 when the user separates it from the insect net 160 for use only. This allows the blackout curtain 170 to be neatly organized.
[0053] The front windshield fixing ring 180, the front fixing block 181, and the rear fixing block 185 are used to fix the upward-rolling transparent windshield 150 and the insect net 160, respectively.
[0054] Reference Figures 1 to 7b This invention describes the usage process of the vehicle insect net assembly 100 of this utility model with this structure.
[0055] The car insect screen assembly 100 can be manufactured and sold according to the shape of the trunk lid 20 of various vehicles. Users purchase the car insect screen assembly 100 suitable for the type of vehicle to which it will be installed. In order to... Figure 2 The unfolded vehicle insect net assembly 100 is connected to the vehicle 10. The overall disassembly zipper 130 is opened, leaving only the vehicle connector 110 and the base component 120, and the rest of the components are separated.
[0056] Then, as Figure 5a As shown, after opening the trunk door 20 of vehicle 10, separate the sealing strip 30 that wraps around the door panel 13 and the insert piece 11. At this time, do not separate the entire sealing strip 30, but only gradually separate the area to be embedded in the vehicle connector 110.
[0057] The user opens the vehicle connector 110 and inserts the door panel 13 into the embedding space 114, applying pressure to fix the front and rear side walls 113 and 115 of the door panel 13 against the front and rear walls of the door panel 13. After the vehicle connector 110 is fully embedded along the entire edge of the trunk door opening, as shown... Figure 5b The embedded sealing strip 30 is now assembled. Then, the zipper connectors 140 and 140a are connected to the integral detachable zipper 130 for use in the desired configuration.
[0058] like Figure 6a As shown, the user can use the device with the triple-layered screen structure—transparent windbreak 150, insect net 160, and blackout curtain 170—fully extended. In this configuration, it not only blocks rain or wind but also obstructs external views, protecting privacy.
[0059] like Figure 6b As shown, the transparent wind deflector 150 can be selectively removed for use. After opening the wind deflector zipper 151, the separated transparent wind deflector 150 is rolled up upwards and secured to the front fixing block 181 via the front wind deflector fixing ring 180. With the transparent wind deflector 150 rolled up, only the insect screen 160 and the blackout curtain 170 are operational, allowing airflow while maintaining insect blocking and privacy protection. Therefore, it is useful in situations where ventilation is needed but insect intrusion and external visibility are blocked.
[0060] In addition, such as Figure 7aAs shown, depending on the situation, the blackout curtain zipper 171 can be opened to partially detach the blackout curtain 170 from the insect net 160. The detached blackout curtain 170 is rolled down and inserted into the blackout curtain pocket 173a for safekeeping. In this state, only the insect net 160 is operational, maintaining insect protection while ensuring visibility to the outside. Therefore, it is suitable for situations where basic protection is desired while enjoying the surrounding scenery.
[0061] In addition, such as Figure 7b As shown, the overall disassembly zipper 130 is separated as needed, leaving only the vehicle connector 110 and the base component 120, removing all triple screens. This provides the user with a completely open feel. It can be used when you want a complete sense of integration with nature in a good weather and safe environment.
[0062] On the other hand, although not shown in the figure, depending on the situation, the wind deflector zipper 151 can be kept closed, and only the insect net zipper 161 can be opened. The insect net 160 and the blackout curtain 170 can then be rolled up together and secured by the rear fixing block 185 and the fixing ring. In this case, only the transparent wind deflector 150 is unfolded, ensuring a view of the surrounding landscape during rain or wind.
[0063] On the other hand, although not shown in the figure, only the sunshade 170 can be deployed. That is, the insect net zipper 161 and the wind deflector zipper 151 are separated, and the insect net 160 and the transparent wind deflector 150 are rolled up and fixed, so that the sunshade 170 completely blocks the opening of the trunk door 20.
[0064] In this configuration, complete visual obstruction from the outside is achieved, but there is no physical blockage against insects or wind, allowing for natural ventilation. Using only a 170mm blackout curtain may be suitable for situations such as campsites or parking lots where complete obstruction of others' view is possible while allowing fresh air to flow in.
[0065] The vehicle insect net assembly of this utility model can flexibly cope with various environmental changes through the triple screen structure of transparent windshield, insect net and sunshade.
[0066] In addition, the transparent windbreak, insect net, and blackout curtain can be operated independently, allowing users to selectively use insect-proof, wind-proof, and privacy protection functions as needed.
[0067] In addition, the structure with the height difference between the two side walls of the vehicle connector improves the bonding force with the vehicle, and has the advantage of being stable and fixed even in wind or vibration.
[0068] In addition, the sunshade curtain's storage structure allows it to be neatly organized when not in use, thus improving the utilization of interior space.
[0069] The technical concept of this utility model has been examined through several embodiments above.
[0070] It will be apparent to those skilled in the art that various modifications or alterations can be made to the embodiments examined above based on the description of this utility model. Furthermore, even if not explicitly shown or described, it will be apparent to those skilled in the art that various modifications incorporating the technical concept of this utility model can be made based on the description of this utility model, and these modifications still fall within the scope of this utility model.
