[0041] Embodiment 1

[0042] Referring to Figure 1 - Figure 3 , which is the first embodiment of the present utility model, a connection structure is provided. This device includes

[0043] Fixing unit 100, including support base 101, positioning member 102 and clamping assembly 103. Among them, the positioning member 102 is arranged on the support base 101, and the clamping assembly 103 is arranged on one side of the positioning member 102; and, the support base 101 is used to fixedly support the fixing plate 103a in the positioning member 102 and the clamping assembly 103. The positioning member 102 is arranged in the limit base 202, which is used to enhance the stability of the clamping assembly 103 in the fastener 203 and prevent the vibration caused by bumps from affecting the stability of the clamping assembly 103 in the fastener 203.

[0044] Connecting unit 200, including support base 201, limit base 202 and fastener 203. Among them, the support base 201 is arranged on the support base 101, the limit base 202 which is arranged on the support base 201 and matches the positioning member 102, and the fastener 203 which is arranged on the support base 201 and matches the clamping assembly 103. The support base 201 is used to fixedly support the limit base 202 and the fastener 203. The limit base 202 is used to guide the installation of the positioning member 102, increasing the convenience of installing the clamping assembly 103 in the fastener 203. The fastener 203 is used to clamp the clamping assembly 103, so as to stably and simply install the support base 201 on the support base 101. Avoid using screw connection, which will prolong the assembly time between the support base 101 and the support base 201 and reduce the possibility of connection stability due to loosening.

[0045] Among them, the clamping assembly 103 includes a fixing plate 103a arranged on the support base 101 and a clamping head 103b arranged on the fixing plate 103a. The fixing plate 103a is used to fixedly support the clamping head 103b. The clamping head 103b passes through the slot 203c on the fastener 203, and the clamping head 103b firmly clamps on the surface of the cap 203a.

[0046] During the use process, the installer first checks whether the surfaces of the positioning member 102, the clamping assembly 103 and the fastener 203 are damaged. On the premise of no damage, the installer passes the positioning member 102 through the limit base 202. This operation is used to guide and position the installation of the support base 201 on the support base to prevent the initial position of the support base 201 from shifting when installed on the support base 101, thus reducing the installation efficiency. Then the installer passes the clamping head 103b through the slot 203c on the cap 203a and fixes the clamping head 103b on the surface of the cap 203a. The fixing plate 103a and the clamping head 103b are made of PP-T20 material. PP-T20 is a plastic material, specifically a material in which 20% talcum powder is added to polypropylene. The density of this material is about 1.12g / cm 3, the melting temperature is not lower than 158 °C. PP-T20 has excellent fluidity, high hardness, high impact strength and good dimensional stability. The elongation at break of PP-T20 can reach 66.0%, which indicates that it has certain toughness and can withstand a certain amount of deformation without breaking. The slot 203c and the card connector 103b adopt a dislocation design. The card connector 103b and the fixing plate 103a are deformed during the process of passing through the slot 203c and return to their original state after passing through the slot 203c. Moreover, the PP-T20 material also complies with the RoHS standard, ensuring its safety and environmental protection.

[0047] By using the limit base 202 to guide and position the positioning member 102, it is possible to ensure the accurate alignment of the support base two 201 when it is installed on the support base one 101, reduce the readjustment caused by position deviation, and thus improve the overall installation efficiency. The design of the clamping assembly 103 enables the card connector 103b to firmly clamp on the surface of the card cap 203a, reduces the looseness caused by bumps or vibrations, and enhances the stability of the connection. Compared with the traditional screw connection, the design of the clamping assembly 103 avoids the use of screws, thereby reducing the time consumption in the assembly process and making the entire assembly process faster and simpler.

[0048] Embodiment 2

[0049] Refer to Figure 1 - Figure 5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the tip orientation direction of the card connector 103b is set as the front direction, and the back direction of the tip of the card connector 103b is set as the rear direction;

[0050] The clamping assembly 103 further includes a front support plate 103c arranged in the front direction of the fixing plate 103a, a rear support plate 103d arranged in the rear direction of the fixing plate 103a, and a side support plate 103e arranged on the fixing plate 103a. On the fixing plate 103a, two front support plates 103c are arranged. The two front support plates 103c are symmetrically arranged about the central axis of the fixing plate 103a in the vertical direction to ensure the balance of the structure of the fixing plate 103a in the dark slot 203b. At the same time, the rear support plate 103d is located on the other side of the fixing plate 103a and is precisely set on the central axis in the horizontal direction, forming an opposing layout with the front support plate 103c. Such a design not only ensures the uniformity of support but also maintains the stability of the overall structure.

[0051] Compared with Embodiment 1, further, one end of the positioning member 102 is conical, and the limiting base 202 is cross-shaped. Designing one end of the positioning member 102 to be conical while the limiting base 202 is cross-shaped brings significant stability to the positioning and guiding of the positioning member 102 in the limiting base 202.

[0052] One conical end of the positioning member 102 can closely cooperate with the cross-shaped structure of the limiting base 202. The progressive contact surface of the cone helps guide the positioning member 102 to smoothly and accurately enter the limiting base 202, reducing errors and friction during installation. The cross-shaped limiting base 202 provides contact points in multiple directions, enhancing the stability of the positioning member 102 during installation and ensuring the precise alignment of the positioning member 102 in multiple directions.

[0053] In addition, this structural design also helps improve the installation efficiency of the entire clamping assembly 103 because it reduces the time for adjustment and alignment. At the same time, it can also improve the reliability of the assembly during actual use because the cooperation between the cone and the cross shape can effectively resist displacement or rotation caused by external forces, thus ensuring long-term stability and durability.

[0054] Among them, the fastener 203 includes a cap 203a provided on the second support base 201, a blind groove 203b provided on the cap 203a, and a card slot 203c provided on the cap 203a. The cap 203a and the card slot 203c are used to fix the card joint 103b, and the blind groove 203b cooperates with the front support plate 103c and the rear support plate 103d on the fixing plate 103a to enhance the stability of the clamping assembly 103 in the cap 203a. The card slot 203c directly engages with the card joint 103b to ensure the firmness of the connection, while the blind groove 203b matches the front and rear support plates 103d on the fixing plate 103a to provide additional support for the clamping assembly 103, effectively reducing the impact of vibration on the connection stability.

[0055] During use, during the assembly process, the installer first locates the card joint 103b to pass through the card slot 203c and fix it on the surface of the card cap 203a. During this process, the positioning member 102 will pass through the limit base 202 to position the second support base 201 installed on the first support base 101. One end of the positioning member 102 with a conical shape cooperates with the cross-shaped limit base 202. The progressive contact surface design of the cone enables the positioning member 102 to be smoothly and accurately installed in place, reducing errors and friction during the installation process. The cross-shaped structure of the limit base 202 provides contact points in multiple directions, which not only enhances the stability of the positioning member 102 but also ensures its precise alignment during installation. This not only improves the installation efficiency and reduces the time for adjustment and alignment but also enhances the reliability of the component during actual use, effectively resisting displacement or rotation caused by external forces and ensuring long-term stability and durability.

[0056] The remaining structures are the same as those in Embodiment 1.

[0057] Embodiment 3

[0058] Referring to Figure 1 - Figure 10 , which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that an automotive front defrosting air duct 302 further includes,

[0059] The defrosting unit 300 includes a front defrosting panel 301 disposed on the first support base 101, a front defrosting air duct 302 disposed on the front defrosting panel 301, and an installation positioning component 303 disposed on the front defrosting panel 301; and, as the main body part of the defrosting unit 300, the front defrosting panel 301 provides a solid base for installing other components. The front defrosting air duct 302 installed on the front defrosting panel 301 is responsible for guiding the air flow to achieve the defrosting effect. The installation positioning component 303 includes a guide plate 303a and a guide head 303b, which are disposed on the front defrosting panel 301 and are used to ensure the correct positioning and installation of the front defrosting panel 301 on the vehicle.

[0060] The air guiding unit 400 includes a wind guiding plate 401 disposed on the front defrosting air duct 302 and an air guiding opening 402 disposed on the wind guiding plate 401. The wind guiding plate 401 is installed on the front defrosting air duct 302 and is used to control and guide the direction of the air flow to optimize the defrosting effect. The air guiding opening 402 is disposed on the wind guiding plate 401, and the air guiding opening 402 further refines the distribution of the air flow to ensure that the defrosting area is evenly affected by the wind. Moreover, the second support base 201 is installed on the wind guiding plate 401, and the first support base 101 is installed in the front defrosting air duct 302. The installation of the wind guiding plate 401 in the front defrosting air duct 302 realizes a snap connection. Compared with the traditional screw connection, the design of the snap connection assembly 103 avoids the use of screws, thereby reducing the time consumption in the assembly process and making the assembly process of the wind guiding plate 401 and the front defrosting air duct 302 faster and more convenient.

[0061] Compared with Embodiment 2, further, the installation and positioning component 303 includes a guiding plate 303a disposed on the front defrosting panel 301 and a guiding head 303b disposed on the guiding plate 303a. The guiding plate 303a is disposed on the front defrosting panel 301 to provide guiding and positioning for other components during the installation process.

[0062] Wherein, a connecting plate 303c is disposed on the guiding head 303b. The guiding head 303b and the bolt sleeve 303d are connected together. The connecting plate 303c is provided with the bolt sleeve 303d. The bolt sleeve 303d is provided with an installation hole 303e, and the bolt sleeve 303d is provided with the guiding plate 303a. The bolt sleeve 303d is provided with the installation hole 303e for fixing the front defrosting panel 301 to the vehicle through the bolt and the installation hole 303e.

[0063] Wherein, an installation clip 304 is disposed on the front defrosting panel 301, and an installation groove 305 matching the wind guiding plate 401 is disposed in the front defrosting air duct 302. The installation clip 304 is disposed on the front defrosting panel 301, and these clips match the installation parts on the vehicle to ensure that the front defrosting panel 301 is firmly fixed to the vehicle. The installation groove 305 is used for the front defrosting air duct 302 to fixedly support the wind guiding plate 401.

[0064] During use, during installation, first align the front defrost air duct 302 with the mounting clips 304 on the front defrost panel 301 and the mounting parts on the vehicle, and then perform guiding and fixing through the bolt sleeve 303d and the guiding head 303b. Next, install the air deflector 401 on the front defrost air duct 302 to ensure that the air outlet 402 is correctly aligned to achieve the best air flow distribution. Finally, use the guiding plate 303a and the guiding head 303b in the installation positioning component 303 to ensure the correct alignment and stable installation of all components. By using the guiding plate 303a and the guiding head 303b, the front defrost panel 301 and the mounting parts on the vehicle can be accurately aligned, thereby reducing the assembly gap and improving the overall assembly accuracy.

[0065] The remaining structure is the same as that of Embodiment 2.
