[0001] This utility model relates to the field of automotive parts technology, and in particular to a high-temperature resistant automotive plastic air intake pipe connection structure. Background Technology

[0002] In automotive powertrain systems, the intake manifold, as a crucial air delivery channel, directly impacts engine intake efficiency and combustion performance. Plastic materials, due to their advantages such as light weight, good moldability, and controllable cost, are widely used in the manufacture of automotive intake manifolds. Because the engine compartment of a car has a compact layout and is constantly exposed to high temperatures (affected by engine cooling, ambient temperature, etc.), and because continuous vibrations occur during vehicle operation, specific requirements are placed on the connection structure of the plastic intake manifold. This utility model relates to a high-temperature resistant automotive plastic intake manifold connection structure.

[0003] In the existing automotive plastic intake pipe connection technology, there is a significant lack of protection design for the key connection parts of the intake pipe. Most existing structures do not have dedicated wrap-around protective components, which cannot effectively prevent external dust and impurities from entering the intake pipe connection parts. Long-term use can easily lead to the accumulation of impurities, which may not only affect the cleanliness of the intake system, but also cause corrosion to the connection parts, thereby reducing the service life of the intake pipe.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please refer to Figures 1 to 6 Example 1: This utility model proposes a high-temperature resistant automotive plastic air intake pipe connection structure, including: a plate base 1; a fixing post 11 is fixedly installed on the upper end of the plate base 1, a base 2 is fixedly installed on the fixing post 11, a connecting seat 21 is installed on the base 2 by bolts, a rotatable rotating seat 22 is installed on the connecting seat 21, a first locking bolt 211 is threaded onto the connecting seat 21, a rotatable rotating disk 23 is installed on the rotating seat 22, and a second locking bolt 221 is installed on the rotating seat 22, and a fixing support is fixedly installed on the rotating disk 23. A first clamping arm 241 is fixedly installed on the frame 24, and a second clamping arm 242 is hinged to the first clamping arm 241. Rubber pads 2412 are installed on both the first clamping arm 241 and the second clamping arm 242. Two clamping covers 243 are clamped between the first clamping arm 241 and the second clamping arm 242, and two protective sleeves 244 are clamped between the two clamping covers 243. Each of the two protective sleeves 244 is provided with a positioning groove 2441, and each of the two clamping covers 243 is provided with a positioning protrusion 2431 that cooperates with the positioning groove 2441.

[0025] In this embodiment of the utility model, two side plates 14 are bolted to the plate base 1. Each side plate 14 is hinged with a clamping plate 15. Two anti-slip plates 151 are fixed to the lower end of the clamping plate 15. Both anti-slip plates 151 are provided with anti-slip texture. Their function is to adjust the opening angle of the clamping plate 15 through the hinged cooperation between the side plate 14 and the clamping plate 15, so as to fix the entire connection structure to the mounting base or corresponding support of the car. The anti-slip plate 151 at the lower end of the clamping plate 15 and the anti-slip texture on the plate can greatly increase the friction between the clamping plate 15 and the mounting surface, and prevent the connection structure from sliding or shifting due to vibration and bumps during the car's operation. This further improves the stability of the structure installation and provides a basic guarantee for the reliable connection of the intake pipe.

[0026] In Embodiment Two, based on Embodiment One, a round rod 152 is fixedly installed on the upper end of each of the two clamping plates 15. A movable first movable block 154 is installed on the round rod 152, and a second movable block 153 is installed on the first movable block 154 via a pin. A fixed seat 12 is fixed on the plate base 1, and two rail rods 111 are fixedly installed between the fixed seat 12 and the fixed column 11. A movable plate 13 is installed on the rail rods 111, and a first connecting plate 131 and a second connecting plate 123 are respectively connected to the movable plate 13 and the fixed seat 12 via pins. Both the first connecting plate 131 and the second connecting plate 123 are installed on the second movable block 153 via pins. Above, a lead screw 121 is installed between the fixed column 11 and the fixed seat 12 via a bearing. The lead screw 121 is threadedly engaged with the movable plate 13. A knob 122 is installed on the lead screw 121. Its function is to rotate the knob 122 to drive the lead screw 121 to rotate. By utilizing the threaded engagement between the lead screw 121 and the movable plate 13, the movable plate 13 is driven to slide stably along the rail 111. When the movable plate 13 slides, it will drive the second movable block 153 and the first movable block 154 to move along the round rod 152 through the first connecting plate 131 and the second connecting plate 123. This will then pull the clamping plate 15 to open and close around the hinge point of the side plate 14, thereby realizing the clamping or loosening operation of the mounting surface.

[0027] In Example 3, based on Examples 1 and 2, a waist-shaped through groove is provided on the first clamping arm 241, and a locking screw 2411 is installed in the waist-shaped through groove. A threaded hole is provided on the second clamping arm 242, and the locking screw 2411 is threaded into the threaded hole on the second clamping arm 242. A spring is installed on the locking screw 2411, and the spring is located between the first clamping arm 241 and the second clamping arm 242. Its function is: rotating the locking screw 2411 can adjust the opening degree of the first clamping arm 241 and the second clamping arm 242, thereby realizing the clamping or disassembly of the clamping cover 243. The waist-shaped through groove can provide a certain amount of movement space for the adjustment of the locking screw 2411. At the same time, the spring located between the first clamping arm 241 and the second clamping arm 242 can form a buffer by its own elastic deformation.

[0028] The working principle of this embodiment is as follows: First, by adjusting the knob 122 on the plate base 1, the lead screw 121 between the fixed column 11 and the fixed base 12 is rotated. Utilizing the threaded engagement between the lead screw 121 and the movable plate 13, the movable plate 13 is driven to slide along the two rails 111. When the movable plate 13 slides, the second movable block 153 is moved by the first connecting plate 131 and the second connecting plate 123 on the fixed base 12. The second movable block 153 is then connected to the first movable block 154 by a pin, pulling the first movable block 154 along the round rod 152 at the upper end of the clamping plate 15. The movement causes the clamping plate 15 to open and close around the hinge point of the side plate 14, thereby clamping and fixing the mounting surface. The anti-slip texture on the anti-slip plate 151 at the lower end of the clamping plate 15 enhances the stability of the fixation. Then, the air intake pipe is placed inside the two protective sleeves 244 and clamped by the two clamping covers 243. The locking screw 2411 is rotated to clamp the first clamping arm 241 and the second clamping arm 242 against the clamping cover 243, thus achieving a stable connection and fitting installation of the air intake pipe. The structure of the protective sleeve 244 and the clamping cover 243 can form a wrap-around protection for the key connection parts of the air intake pipe.
