Description

Technical Field

[0001] This invention relates to the field of modular automotive sensor technology, specifically to a modular assembled automotive sensor. Background Technology

[0002] With the rapid development of the automotive industry, automotive sensors are playing an increasingly important role in vehicle driving safety and performance monitoring. Currently, most automotive sensors on the market adopt an integrated design. When a sensor malfunctions and requires repair or replacement, the entire sensor assembly often needs to be disassembled, which is cumbersome and costly. Furthermore, the heat dissipation structure of traditional automotive sensors is fixedly connected to the sensor body, making it impossible to flexibly adjust or replace it according to actual heat dissipation needs. Damage to the heat dissipation structure can also affect the normal operation of the sensor. In addition, traditional automotive sensors are difficult to adjust flexibly according to the actual installation location during installation, resulting in poor installation convenience.

[0003] To address the aforementioned issues, this invention proposes a modular assembly-type automotive sensor. By modularizing the sensor unit and heat dissipation components, the sensor unit and heat dissipation components can be independently disassembled, replaced, and adjusted, improving maintenance convenience, reducing maintenance costs, and also enhancing the flexibility of sensor installation and the controllability of heat dissipation. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] This invention is proposed in view of the problems existing in existing modular assembled automotive sensors.

[0006] Therefore, the purpose of this invention is to provide a modular, assembled automotive sensor to solve the problems mentioned in the background art, such as inconvenient maintenance, inflexible heat dissipation structure, and poor installation flexibility of traditional automotive sensors.

[0007] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A modular, assembled automotive sensor includes a base on which a sensor mounting assembly and a radiator mounting assembly are disposed; Sensor fixing assembly: includes a fixing platform, an adjusting screw is threadedly connected to the fixing platform, one end of the adjusting screw is connected to a movable platform, a first spring is installed on the movable platform, the other end of the first spring is connected to a first limiting block, the first limiting block is engaged with a sensor mounting base, and a sensor unit is installed on the sensor mounting base; Heat sink fixing assembly: includes a limiting platform, with a second spring provided on the inner wall at both ends of the limiting platform, the other end of the second spring being connected to a second limiting block, the second limiting block being engaged with the heat sink frame, and a heat sink fan being installed inside the heat sink frame.

[0008] As a preferred embodiment of the modular assembled automotive sensor of the present invention, the base has a sliding groove at its bottom, and a fixing screw and a fixing block are installed in the sliding groove. The fixing screw is rotatably connected to the base and threadedly connected to the fixing block.

[0009] As a preferred embodiment of the modular assembled automotive sensor of the present invention, one end of the fixing screw extends to the outside of the base, and a hexagonal groove is formed on the end face of the extended portion.

[0010] In a preferred embodiment of the modular assembled automotive sensor described in this invention, the fixed platform is fixedly connected to the base, the movable platform is slidably connected to the base, and the movable platform is rotatably connected to the adjusting screw.

[0011] As a preferred embodiment of the modular assembled automotive sensor of the present invention, the sensor mounting base is provided with first limiting grooves on both sides, the first limiting block is located in the first limiting groove, and the cross-section of the first limiting groove and the first limiting block is trapezoidal.

[0012] As a preferred embodiment of the modular assembled automotive sensor of the present invention, the heat sink is provided with second limiting grooves on both sides, the second limiting block is located in the second limiting groove, and the cross-section of the second limiting groove and the second limiting block is trapezoidal.

[0013] In a preferred embodiment of the modular assembled automotive sensor described in this invention, the fixing platform is located on both sides of the base, and side plates are provided on both sides of the fixing platform.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. It adopts a modular design, and the sensor unit and heat dissipation component can be disassembled and replaced independently. When a single component, such as the sensor unit or the heat dissipation fan, is damaged, it is not necessary to replace the entire sensor assembly, but only to replace the faulty part, which greatly reduces the cost of spare parts procurement; at the same time, it is not necessary to disassemble the overall structure during maintenance, which shortens maintenance time and reduces labor costs.

[0015] 2. The sliding groove at the bottom of the base cooperates with the fixing screw to adjust the position of the fixing block according to the installation space and mounting hole position of different vehicle models, adapting to the installation needs of various vehicle models; the adjusting screw in the sensor fixing assembly can finely adjust the position of the sensor unit to ensure that the detection end is accurately aligned with the monitoring point, avoiding installation deviation problems caused by vehicle model differences and improving product versatility.

[0016] 3. The heat dissipation components adopt a replaceable design, allowing for the replacement of cooling fans with different power and airflow rates according to the sensor's operating conditions (such as engine compartment in high-temperature environments or chassis in low-temperature environments), avoiding the problems of excessive or insufficient heat dissipation in traditional fixed heat dissipation structures. In addition, the tight snap-fit ​​between the heat dissipation bracket and the limiting platform can reduce the gap in the heat dissipation air duct, improve heat dissipation efficiency, and ensure that the sensor unit is always in the optimal operating temperature range, avoiding the decrease in detection accuracy or failure due to overheating.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] This invention provides the following technical solution: a modularly assembled automotive sensor, which adopts a modular disassembly design during use, allowing the sensor unit and heat dissipation component to be independently disassembled and replaced. When a single component, such as the sensor unit or the cooling fan, is damaged, it is not necessary to replace the entire sensor assembly; only the faulty part needs to be replaced, significantly reducing spare parts procurement costs. At the same time, maintenance does not require disassembling the overall structure, shortening maintenance time and reducing labor costs.

[0024] The sliding groove at the bottom of the base works with the fixing screw to adjust the position of the fixing block according to the installation space and mounting hole positions of different vehicle models, adapting to the installation needs of various vehicle models; the adjusting screw in the sensor fixing assembly can finely adjust the position of the sensor unit to ensure that the detection end is accurately aligned with the monitoring point, avoiding installation deviation problems caused by vehicle model differences and improving product versatility.

[0025] The heat dissipation components adopt a replaceable design, allowing for the replacement of cooling fans with different power and airflow rates according to the sensor's operating conditions, such as the engine compartment in high-temperature environments or the chassis in low-temperature environments. This avoids the problems of excessive or insufficient heat dissipation caused by traditional fixed heat dissipation structures. In addition, the tight snap-fit ​​between the heat dissipation bracket and the limiting platform reduces the gap in the heat dissipation airflow, improves heat dissipation efficiency, and ensures that the sensor unit is always in the optimal operating temperature range, avoiding the decrease in detection accuracy or failure due to overheating.

[0026] Figures 1-5 The diagram shown is a structural schematic of a first embodiment of a modular assembled automotive sensor according to the present invention. Please refer to [link / reference]. Figures 1-5 The modular assembled automotive sensor of this embodiment includes a base 100, on which a sensor fixing assembly 200 and a radiator fixing assembly 300 are disposed. Sensor fixing assembly 200: includes a fixing platform 210, an adjusting screw 220 is threadedly connected to the fixing platform 210, one end of the adjusting screw 220 is connected to a movable platform 230, a first spring 240 is installed on the movable platform 230, the other end of the first spring 240 is connected to a first limiting block 250, the first limiting block 250 is engaged with a sensor mounting base 260, and a sensor unit 270 is installed on the sensor mounting base 260; Heat sink fixing assembly 300: includes a limiting platform 310, with second springs 320 provided on the inner walls of both ends of the limiting platform 310, the other end of the second springs 320 being connected to a second limiting block 330, the second limiting block 330 being engaged with a heat sink frame 340, and a heat sink fan 350 being installed inside the heat sink frame 340. The sensor fixing assembly 200 is used to fix and adjust the position of the sensor unit 270. It includes a fixing platform 210, which is fixedly connected to the base 100, providing stable support for the entire sensor fixing assembly 200. An adjusting screw 220 is threaded onto the fixing platform 210, allowing adjustment of the position of the movable platform 230 by rotating the adjusting screw 220. One end of the adjusting screw 220 is rotatably connected to the movable platform 230, ensuring that the movable platform 230 can move when the adjusting screw 220 rotates. The movable platform 230 is slidably connected to the base 100, ensuring the stability of the movable platform 230 during movement. A first spring 240 is installed on the movable platform 230, and the other end of the first spring 240 is connected to a first limiting block 250. The first spring 240 provides an elastic force to the first limiting block 250, causing the first limiting block 250 to tightly engage with the sensor mounting base 260. The first limiting block 250 engages with the sensor mounting base 260, thus securing the sensor mounting base 260. A sensor unit 270 is mounted on the sensor mounting base 260, and the sensor unit 270 is used to detect relevant automotive parameters. To improve the stability of the engagement between the first limiting block 250 and the sensor mounting base 260, the sensor mounting base 260 has first limiting grooves 261 on both sides. The first limiting block 250 is located within the first limiting grooves 261, and both the first limiting grooves 261 and the first limiting block 250 have trapezoidal cross-sections. This trapezoidal design effectively prevents the first limiting block 250 from falling out of the first limiting grooves 261, ensuring the reliability of the connection between the sensor mounting base 260 and the first limiting block 250. The heat sink fixing assembly 300 is used to fix the heat sink fan 350. It includes a limiting platform 310, which provides installation space and positioning for the heat sink bracket 340. Second springs 320 are provided on the inner walls of both ends of the limiting platform 310. The other end of each second spring 320 is connected to a second limiting block 330. The second springs 320 provide elastic pressure to the second limiting block 330, ensuring a tight engagement between the second limiting block 330 and the heat sink bracket 340. The engagement of the second limiting block 330 with the heat sink bracket 340 fixes the heat sink bracket 340 in place. A heat sink fan 350 is installed inside the heat sink bracket 340. The heat sink fan 350 dissipates heat generated during the operation of the sensor unit 270, ensuring the normal operating temperature of the sensor unit 270. Similarly, to improve the stability of the engagement between the second limiting block 330 and the heat sink 340, second limiting grooves 341 are provided on both sides of the heat sink 340. The second limiting block 330 is located within the second limiting grooves 341, and the cross-sections of the second limiting grooves 341 and the second limiting block 330 are trapezoidal. The trapezoidal structure design also prevents the second limiting block 330 from falling out of the second limiting grooves 341, ensuring the reliability of the connection between the heat sink 340 and the second limiting block 330. In addition, the fixed platform 210 is located on both sides of the base 100, and side plates are provided on both sides of the fixed platform 210. The side plates can limit the movement range of the movable platform 230, preventing the movable platform 230 from exceeding the preset range during movement, and can also provide a certain degree of protection for the sensor fixing assembly 200. To facilitate the installation of the sensor in a designated location on the vehicle, a sliding groove 110 is provided at the bottom of the base 100. A fixing screw 120 and a fixing block 130 are installed within the sliding groove 110. The fixing screw 120 is rotatably connected to the base 100 and threadedly connected to the fixing block 130. By rotating the fixing screw 120, the fixing block 130 can be moved within the sliding groove 110, thereby adjusting the position of the fixing block 130 according to the actual installation location, thus achieving a fixed installation of the entire sensor. To facilitate the rotation of the fixing screw 120, one end of the fixing screw 120 extends outside the base 100, and a hexagonal groove is formed on the end face of the extended part. Operators can use a hexagonal wrench to insert into the hexagonal groove to easily rotate the fixing screw 120, improving operational convenience.

[0027] Combination Figures 1-5The modular assembly automotive sensor of this embodiment operates on the following principle: When installing the sensor unit 270, the sensor unit 270 is first installed on the sensor mounting base 260. Then, the sensor mounting base 260 is placed between the movable platform 230 and the fixed platform 210. By rotating the adjusting screw 220, the movable platform 230 is moved closer to the sensor mounting base 260. At this time, the first spring 240 is compressed and generates an elastic force, pushing the first limiting block 250 into the first limiting grooves 261 on both sides of the sensor mounting base 260, thereby fixing the sensor mounting base 260. Since the cross-sections of the first limiting grooves 261 and the first limiting block 250 are trapezoidal, the sensor mounting base 260 can be effectively prevented from falling off, ensuring the stability of the fixation. When installing the cooling fan 350, the cooling fan 350 is installed inside the heat sink bracket 340, and then the heat sink bracket 340 is placed inside the limiting platform 310. At this time, the second spring 320 pushes the second limiting block 330 into the second limiting grooves 341 on both sides of the heat sink bracket 340, thereby fixing the heat sink bracket 340. Similarly, the trapezoidal structure of the second limiting groove 341 and the second limiting block 330 can ensure the stability of the heat sink bracket 340. When installing the entire sensor onto the vehicle, depending on the actual installation location, use a hex wrench to insert into the hexagonal groove at the extension end of the fixing screw 120, rotate the fixing screw 120 to move the fixing block 130 within the sliding groove 110, adjust the position of the fixing block 130 so that it fits tightly with the mounting structure on the vehicle, thereby achieving the fixed installation of the entire sensor. When sensor unit 270 malfunctions and requires repair or replacement, simply rotate the adjusting screw 220 in the reverse direction to move the movable table 230 away from the sensor mounting base 260. This reduces the pressure of the first spring 240, allowing the sensor mounting base 260 to be removed from the sensor fixing assembly 200 for repair or replacement of sensor unit 270. This eliminates the need to disassemble the entire sensor assembly, making the operation simple. Similarly, when cooling fan 350 malfunctions, simply press the second limit blocks 330 on both sides to compress the second spring 320, allowing the heat sink 340 to be removed from the limiting platform 310 for repair or replacement of cooling fan 350. This operation is equally convenient. Furthermore, the position of the sensor mounting base 260 can be changed by adjusting the adjusting screw 220, thereby adjusting the detection position of the sensor unit 270 and improving the flexibility of sensor use. Simultaneously, depending on actual heat dissipation requirements, cooling fans 350 of different wattages can be replaced to further improve the sensor's heat dissipation effect. In summary, this modular automotive sensor, through its modular design, enables the independent disassembly, replacement, and adjustment of the sensor unit 270 and the heat dissipation components, improving maintenance convenience and installation flexibility. It also ensures the sensor's operational stability and heat dissipation effect, thus possessing high practical value.
