Description

Technical Field

[0001] This utility model relates to the field of automotive electronics technology, and in particular to a surface-mountable dual-zone sensor assembly. Background Technology

[0002] As automobiles transform from simple means of transportation into intelligent living spaces, users' demands for in-car comfort are becoming increasingly sophisticated. Traditional in-car environmental control systems (such as temperature and lighting regulation) employ a uniform management model, which cannot meet the differentiated needs of occupants in different areas (such as the driver, front passenger, and rear passengers). For example, elderly passengers may prefer higher temperatures, while child passengers need to avoid direct sunlight. Such personalized needs render the traditional "one-size-fits-all" control method significantly limited.

[0003] In the existing technology, although some car companies have proposed the concept of zone control, its implementation mostly relies on the dispersed arrangement of independent sensor modules, resulting in high assembly complexity and low patching efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a surface-mountable dual-zone sensor assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patchable dual-zone sensor assembly, comprising: a symmetrical base with symmetrical mounting structures on both sides, wherein the mounting structures are inclined mounting channels for fixing two sensors and assembling them at a preset tilt angle; each mounting structure is provided with an elastic limiting component, and the sensors are provided with limiting edges on both sides that cooperate with the elastic limiting components; when the sensors are pressed into the mounting structures, the elastic limiting components deform and reset, locking the limiting edges to fix the sensor position; the sensors are symmetrically provided with solder feet at their opposite ends, and the symmetrical base is provided with clearance holes at both ends for the solder feet to pass through.

[0006] As a preferred embodiment of this utility model, the installation channel is an inclined groove, the extension direction of which forms an inclined angle with the central axis of the symmetrical base, and the elastic limiting components are provided on both sides of the inclined groove.

[0007] As a preferred embodiment of this invention, the height of the inner end of the inclined groove is higher than the height of the end where the weld foot is located, forming a height gradient.

[0008] As a preferred technical solution of this utility model, the symmetrical base includes two mounting parts on the left and right, and the mounting parts form a preset angle between them, so that the inclined grooves on both sides are arranged in a figure-eight shape.

[0009] As a preferred technical solution of this utility model, the preset included angle between the left and right mounting parts is 20°~40°.

[0010] As a preferred technical solution of this utility model, the elastic limiting component is an elastic block with a guide slope on its top inner side, and the limiting edge is a blocking edge on both sides of the sensor. The blocking edge is limited to the bottom of the elastic block after being opened by the guide slope.

[0011] As a preferred embodiment of this utility model, the weld leg is an L-shaped bent structure, with its end extending outside the clearance hole.

[0012] As a preferred embodiment of the present invention, the clearance hole includes a first through hole on the side wall of the symmetrical base and a second through hole on the bottom wall, wherein the first through hole and the second through hole are interconnected.

[0013] As a preferred technical solution of this utility model, the elastic limiting component is made of elastic plastic material, and its deformation and reset force are adapted to the assembly requirements of the sensor.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by integrating two sensors into a symmetrical base to form a sub-assembly, and adapting the solder foot layout and clearance hole design to the surface mount soldering process, the installation of dual-zone sensors can be completed in a single surface mount process. Compared with the traditional separate surface mount process, this improves production efficiency, reduces solder paste consumption and equipment debugging time, and lowers manufacturing costs.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 The illustrated patchable dual-zone sensor assembly includes: a symmetrical base 1 with symmetrical mounting structures on both sides, wherein the mounting structures are inclined mounting channels 2 for fixing two sensors 14 at a preset tilt angle; each mounting structure has an elastic limiting component 3, and the sensors 14 have limiting edges 4 on both sides that cooperate with the elastic limiting component 3. When the sensors 14 are pressed into the mounting structures, the elastic limiting component 3 deforms and resets, locking the limiting edges 4 to fix the position of the sensors 14; the ends of the sensors 14 that are far apart from each other are symmetrically provided with solder feet 5, and the two ends of the symmetrical base 1 have passages for the solder feet 5 to pass through. The clearance hole 6, in this embodiment, the elastic limiting component 3 is made of elastic plastic material, and its deformation and restoring force are adapted to the assembly requirements of the sensor 14. The cooperation mechanism between the elastic limiting component 3 (such as the elastic block 9) and the blocking edge of the sensor 14, through the guide slope 10, enables tool-free quick assembly, and after locking, it cannot be adjusted, avoiding human operation errors; through the independent layout and signal processing of the dual-zone sensor 14, parameters such as temperature and light can be adjusted separately for the driver and passenger areas, solving the limitation of the traditional system's "one-size-fits-all" approach, such as the differentiated needs of elderly passengers' preferred temperature zone and children's anti-glare zone, significantly improving the user experience.

[0023] By integrating two sensors 14 into a symmetrical base 1 to form a sub-assembly, the layout of the solder feet 5 and the design of the clearance holes 6 are adapted to the surface mount soldering process. The sensors are fixed on the circuit board 13 by surface mount soldering, which can complete the installation of dual-zone sensors 14 in a single surface mount process. Compared with the traditional separate surface mount process, this improves production efficiency, reduces solder paste consumption and equipment debugging time, and lowers manufacturing costs.

[0024] The installation channel 2 is an inclined groove 7, the extension direction of which forms an inclined angle with the central axis of the symmetrical base 1, and the two side walls of the inclined groove 7 are provided with the elastic limiting component 3.

[0025] The height of the inner end of the inclined groove 7 is higher than the height of the end where the welding foot 5 is located, forming a height gradient. The symmetrical base 1 includes two mounting parts 8 on the left and right, and a preset angle is formed between the mounting parts 8, so that the inclined grooves 7 on both sides are arranged in a figure-eight shape. The preset angle between the two mounting parts 8 on the left and right is 20°~40°. In this embodiment, the left and right mounting parts 8 of the symmetrical base 1 adopt a figure-eight arrangement design, so that the inclined grooves 7 on both sides form a preset angle. Under the premise of ensuring the independent detection function of the dual-zone sensor 14, the lateral dimension is reduced, which is especially suitable for the installation requirements of narrow spaces such as the dashboard and center console area in the vehicle.

[0026] The elastic limiting component 3 is an elastic block 9, with a guide slope 10 on its inner top side. The limiting edge 4 is a blocking edge on both sides of the sensor 14. After the blocking edge opens the elastic block 9 through the guide slope 10, it is limited to the bottom of the elastic block 9.

[0027] The solder foot 5 has an L-shaped bent structure, with its end extending to the outside of the clearance hole 6. The clearance hole 6 includes a first through hole 11 on the side wall of the symmetrical base 1 and a second through hole 12 on the bottom wall. The first through hole 11 and the second through hole 12 are interconnected. The matching design of the L-shaped bent solder foot 5 and the split clearance hole 6 (the first through hole on the side wall and the second through hole on the bottom wall) makes the through path of the solder foot 5 completely match the surface mount welding trajectory, which is conducive to the high-precision positioning of the automated surface mount machine.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
