Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, specifically to an engine intake air flow sensor base. Background Technology

[0002] In the intake system of a car engine, the air flow sensor plays a key role. It accurately measures the air flow entering the engine and converts this information into an electrical signal, which is then transmitted to the electronic control unit (ECU). The ECU then accurately determines the fuel injection quantity and ignition timing, which is crucial for the efficient and stable operation of the engine. The air flow sensor is installed on a mounting base.

[0003] The current engine intake air flow sensor base has a poor compatibility problem: most bases are specially designed and can only match sensors of specific specifications. When the sensor model changes, the base must be replaced accordingly, which increases production costs.

[0004] The purpose of this invention is to provide an engine intake air flow sensor base to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides an engine intake air flow sensor base, comprising a base body: a hollow tubular structure with a base body on its outer wall, a circular mounting opening on the base body for mounting the flow sensor, and a fixed base on the side of the base body near the circular mounting opening, the fixed base having a fixed mounting structure. The fixed mounting structure can be adjusted to adapt to flow sensors of different specifications and achieve fixed installation of the flow sensor. The above design provides a universal base structure, which adapts to flow sensors of different specifications through an adjustable mounting structure, improving installation flexibility and versatility.

[0006] As a further improvement of this utility model, the fixed installation structure includes a first type of adjustment structure, which is a U-shaped groove fixedly set on the fixed base. The position of the bolts in the U-shaped groove is adjusted to adapt to the installation and fixation of flow sensors of different specifications. The U-shaped groove is used to realize the adjustment of the bolt position. The structure is simple and adaptable to the mounting hole positions of different sensors.

[0007] As a further improvement of this utility model, the inner wall of the U-shaped groove is provided with guide ribs extending along the length direction to limit the shaking of the bolt in the groove. The bottom of the U-shaped groove is provided with multiple positioning recesses to assist in fixing the position of the bolt. The guide ribs limit the shaking of the bolt, improve the installation stability, and reduce the displacement caused by vibration.

[0008] As a further improvement of this utility model, the opening edge of the U-shaped groove is provided with a width scale to indicate the range of bolt diameters currently being fitted. The width scale intuitively indicates the fitting range, facilitating quick and accurate installation.

[0009] As a further improvement of this utility model, the bottom of the U-shaped groove is provided with a T-shaped groove extending along the length direction. The T-shaped groove is used to accommodate the head of the T-bolt, restricting the bolt from falling off along the depth direction of the U-shaped groove, and allowing the bolt to slide along the length direction of the T-shaped groove. The T-shaped groove prevents the bolt from falling off, while retaining the sliding adjustment function and enhancing installation safety.

[0010] As a further improvement of this utility model, the fixed installation structure includes a second type of adjustment structure. The second type of adjustment structure includes a fixedly installed U-shaped frame and two adjustment plates. The two adjustment plates are set inside the U-shaped frame and are controlled to move relative to each other in the width direction by the adjustment component. By changing the distance between the two adjustment plates, a channel is formed to adapt to installation bolts of different diameters. The adjustment range is controllable and the adaptability is more precise.

[0011] As a further improvement of this utility model, the adjustment component includes an adjustment screw, which is set at one end of the adjustment plate along the length direction. The adjustment screw is also provided with two opposite threaded sections. The two adjustment plates are respectively threaded to the opposite threaded sections. One end of the adjustment screw is rotatably connected to the inner wall of one side of the U-shaped frame, and the other end extends out to the outer wall of the other side of the U-shaped frame and is connected to an adjustment handle. The adjustment screw and the opposite thread design realize the synchronous and symmetrical movement of the adjustment plate, making the operation convenient and efficient.

[0012] As a further improvement of this utility model, the adjustment handle is also provided with a locking component. The locking component is used to lock the adjustment screw after adjustment. The locking component includes a locking rod and several locking holes. Several locking holes are arranged in a ring around the adjustment screw on the outer wall of the U-shaped frame. The locking rod threaded through the adjustment handle and inserted into the locking hole. The locking component prevents loosening after adjustment and ensures structural stability during long-term use.

[0013] As a further improvement of this utility model, the bottom inner wall of the U-shaped frame is symmetrically provided with slide rails, and the adjustment plate is provided with slide grooves that are adapted to the slide rails at both ends along the width direction of the U-shaped frame. The slide grooves and slide rails slide together to realize the guiding movement of the adjustment plate. The cooperation between the slide rails and slide grooves ensures that the adjustment plate moves smoothly, thereby improving the adjustment accuracy and structural reliability.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, through the design of a fixed installation structure, enables adaptation to flow sensors of different sizes, which not only enhances versatility and simplifies the installation process, but also saves the cost and time of constantly replacing the mounting base due to incorrect size, thus saving costs.

[0024] To facilitate understanding of this utility model, a more comprehensive description of it will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of this utility model more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Please see Figure 1-3 This utility model provides an engine intake air flow sensor base, including a base body 1: which is a hollow tubular structure with a base body 1 on its outer wall. The base body 1 has a circular mounting port 11, which is used to install the flow sensor. A fixed base 12 is also provided on the side of the base body 1 near the circular mounting port 11. The fixed base 12 has a fixed mounting structure 2. The fixed mounting structure 2 can be adjusted by its own structure to adapt to flow sensors of different specifications and realize the fixed installation of the flow sensor.

[0029] The fixed installation structure 2 includes a first type of adjustment structure 21, which is a U-shaped groove 211 fixedly set on the fixed base 12. The position of the bolts in the U-shaped groove 211 is adjusted to adapt to the flow sensor of different specifications for installation and fixation.

[0030] In use, first align the mounting hole of the flow sensor with the U-shaped groove 211, pass a regular hex bolt through the mounting hole of the flow sensor and place it on the U-shaped groove 211. According to the position of the mounting hole of the flow sensor, align the bolt completely with the mounting hole, and at the same time, lock and fix the flow sensor with the nut and the bolt. In this embodiment, the structure is simple and the processing cost is low. The basic adaptation function is achieved through the U-shaped groove, which is suitable for scenarios with low requirements for structural complexity.

[0031] Example 2:

[0032] Based on Embodiment 1, in this embodiment, please refer to... Figure 4 Unlike Embodiment 1, a guide rib 212 is added. The inner wall of the U-shaped groove 211 is provided with a guide rib 212 extending along the length direction to limit the shaking of the bolt in the groove. The bottom of the U-shaped groove 211 is provided with multiple positioning recesses to assist in fixing the position of the bolt.

[0033] When the bolt slides in the U-shaped groove 211, the guide rib 212 provides lateral restraint to the bolt, limiting its sway in the width direction and ensuring that the bolt moves stably only along the length of the groove. This enhances the installation stability of the basic U-shaped groove 211, reduces the risk of bolt displacement under vibration, and significantly improves reliability.

[0034] Example 3:

[0035] Based on Embodiment 1, in this embodiment, please refer to... Figure 5The bottom of the U-shaped groove 211 is provided with a T-shaped groove 214 extending along the length direction. The T-shaped groove 214 is used to accommodate the head of the T-bolt, restrict the bolt from falling out along the depth direction of the U-shaped groove 211, and allow the bolt to slide along the length direction of the T-shaped groove 214.

[0036] The opening edge of the U-shaped groove 211 is provided with a width scale 213 to indicate the range of currently fitted bolt diameters.

[0037] The T-bolt is used, with its head embedded in the T-shaped groove 214. The position can be adjusted by sliding along the length of the groove. At the same time, the T-shaped structure prevents the bolt from falling out along the depth of the U-shaped groove 211. The width scale 213 on the edge of the U-shaped groove opening can intuitively indicate the range of suitable diameters corresponding to the current bolt position, helping to quickly determine the installation position. Tightening the bolt will complete the fixation. After adjustment, tightening the bolt will fix it. The T-shaped groove 214 solves the problem of easy bolt falling out, while retaining the flexibility of sliding adjustment. It is suitable for scenarios that require frequent disassembly and assembly or have large vibrations, and is safer.

[0038] Example 4:

[0039] Based on Embodiment 1, in this embodiment, please refer to... Figure 6-7 The fixed installation structure 2 includes a second type of adjustment structure 22. The second type of adjustment structure 22 includes a fixedly installed U-shaped frame 221 and two adjustment plates 222. The two adjustment plates 222 are set inside the U-shaped frame 221 and are controlled to move relative to each other in the width direction by the adjustment component 223. By changing the distance between the two adjustment plates 222, a channel is formed to accommodate installation bolts of different diameters.

[0040] The adjustment assembly 223 includes an adjustment screw 2231, which is disposed at one end of the adjustment plate 222 along the length direction. The adjustment screw 2231 is also provided with two opposite threaded sections. The two adjustment plates 222 are respectively threadedly connected to the opposite threaded sections. One end of the adjustment screw 2231 is rotatably connected to the inner wall of one side of the U-shaped frame 221, and the other end extends out of the outer wall of the other side of the U-shaped frame 221 and is connected to an adjustment handle 2232.

[0041] The adjustment handle 2232 is also provided with a locking component 224. The locking component 224 is used to lock the adjusted adjustment screw 2231. The locking component 224 includes a locking rod 2241 and several locking holes 2242. The outer wall of the U-shaped frame 221 has several locking holes 2242 arranged in a ring around the adjustment screw 2231. The locking rod 2241 is threaded through the adjustment handle 2232 and inserted into the locking holes 2242.

[0042] The bottom inner wall of the U-shaped frame 221 is symmetrically provided with slide rails 225. The adjustment plate 222 is provided with slide grooves 226 at both ends along the width direction of the U-shaped frame 221 that are adapted to the slide rails 225. The slide grooves 226 and the slide rails 225 slide together to guide the movement of the adjustment plate 222.

[0043] In use, when different specifications of flow sensors need to be installed, the mounting bolts of the flow sensors are passed through the U-shaped frame 221. The operator rotates the adjusting handle 2232, which drives the adjusting screw 2231 to rotate. Since the two opposing threaded sections on the adjusting screw 2231 are threadedly connected to the two adjusting plates 222 respectively, during the rotation of the screw, the two adjusting plates 222 will move relative to each other or in opposite directions along the slide rail 225 under the action of the threads. When the two adjusting plates 222 move relative to each other, the width of the channel between them decreases; when they move in opposite directions, the width of the channel increases, thereby changing the distance between the two adjusting plates 222 to form a channel that can accommodate mounting bolts of different diameters. During the adjustment process, the sliding grooves 226 at both ends of the adjusting plates 222 cooperate with the slide rail 225 at the bottom of the U-shaped frame 221 to guide the movement of the adjusting plates 222, ensuring that the adjusting plates 222 can only move along the set direction. The adjustment process is smooth and precise, avoiding any deviation or jamming. When the flow sensor mounting bolts are engaged and fixed, the operator threaded the locking rod 2241 through the adjusting handle 2232, inserting the end of the locking rod 2241 into the corresponding locking hole 2242 on the outer wall of the U-shaped frame 221. Since the locking rod 2241 is threadedly connected to the adjusting handle 2232, tightening the locking rod 2241 fixes the adjusting handle 2232 relative to the U-shaped frame 221, thereby locking the adjusted adjusting screw 2231. This prevents the adjusting screw 2231 from rotating and changing the spacing of the adjusting plate 222 due to vibrations caused by engine operation, ensuring the stability of the flow sensor installation. The flow sensor installation is then complete. Precise adaptation is achieved through synchronous reverse movement. The locking component 224 and slide rail 225 structure ensure long-term stability, making it suitable for scenarios with high installation accuracy requirements and offering a wider range of compatibility.

[0044] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
