Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to an ultrasonic sensor system. Background Technology

[0002] Ultrasonic radar needs to be fixed to the car bumper using mounting brackets. There are many locations on a vehicle where radar and brackets can be installed (up to 12 locations). Each location requires a different bracket to match the shape of the bumper. Therefore, a vehicle needs to be equipped with a large number of bracket products.

[0003] In related technologies, ultrasonic radar support structures often adopt an integrated design, requiring numerous molds, resulting in a wide variety of products and making management difficult. Furthermore, the high cost of the molds leads to significant waste. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides an ultrasonic sensor system, comprising: a sensor support structure and an ultrasonic sensor, wherein the sensor support structure is a separate support structure, comprising: a bumper matching structure and a core structure;

[0005] Different sensor bracket structures have the same core structure, which is matched and assembled with the bumper matching structure, and the core structure is mechanically fastened to the ultrasonic sensor;

[0006] The bumper matching structure includes: a fixing ring and an angle matching plate; the fixing ring is used to limit the ultrasonic sensor in the radial direction; the bottom surface of the angle matching plate is used to adhere to the bumper.

[0007] Different sensor bracket structures have different bumper matching structures. The angle matching plate in different bumper matching structures has different included angles between its sidewall and the fixing ring to match the bumper shape in different positions.

[0008] Optionally, the core structure includes: an angle plate matching structure, a styling body, and a bracket sidewall. The angle plate matching structure is used to match and assemble with the angle matching plate in the bumper matching structure. The styling body matches the outer side of the bumper. The bracket sidewall is assembled with the ultrasonic sensor by mechanical fastening.

[0009] Optionally, the angle matching plate is relatively small in size compared to the bumper, and the bottom surface of the angle matching plate is a planar structure or an arc surface structure with a small curvature.

[0010] Optionally, the angle matching plate is rectangular in shape.

[0011] The technical solution provided in this application has the following advantages compared with the prior art:

[0012] The detachable sensor bracket structure of this application embodiment includes a bumper matching structure and a core structure, with the core structure and bumper matching structure being assembled together. Different sensor bracket structures can use the same core structure and different bumper matching structures. Different bumper matching structures are relatively simple, the mold making is simple, and the mold cost is low. Therefore, this application can avoid making a mold for the entire bracket structure, but only making a mold for the bumper matching structure with slight differences, thereby reducing the complexity of mold making and thus reducing the cost of mold making.

[0022] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0024] The sensor bracket structure occupies a small area on the vehicle, and the difference in bracket design with the bumper is minimal, resulting in little difference in actual appearance, with only minor variations in the vertical installation angle. Therefore, the molds for existing integrated bracket structures are mostly similar, with minimal differences in shape and angle. This characteristic can be leveraged to construct a separate bracket structure, reducing the complexity and cost of mold making.

[0025] See Figure 1 , Figure 1 This is a schematic diagram showing the components of the ultrasonic sensor system according to an embodiment of this application. The ultrasonic sensor system includes an ultrasonic sensor 1 and a sensor support structure 2. The sensor support structure 2 is a separate support structure, including a bumper matching structure 21 and a core structure 22.

[0026] Different sensor bracket structures 2 share the same core structure 22, which is assembled with the bumper matching structure 21. The core structure 22 is also mechanically fastened to the ultrasonic sensor 1. The assembled ultrasonic sensor system can be found in [reference needed]. Figure 2 and Figure 3 .

[0027] like Figure 4 As shown, the bumper matching structure 21 includes a fixing ring 211 and an angle matching plate 212. The fixing ring 211 is used to limit the ultrasonic sensor 1 in the radial direction; the bottom surface of the angle matching plate 212 is used to adhere to the bumper.

[0028] Different sensor bracket structures 2 have different bumper matching structures 21. The angle matching plate 212 in different bumper matching structures 21 has different included angles between its sidewall and the fixing ring 211 to match the bumper shape at different positions. The included angle between the sidewall of the angle matching plate 212 and the fixing ring 211 is also the included angle between the sidewall of the angle matching plate 212 and the axis of the ultrasonic sensor 1.

[0029] Optionally, the angle matching plate is rectangular in shape, and its size can be, for example, 60*35mm. Optionally, the angle matching plate 212 is relatively small in size compared to the bumper, and the bottom surface of the angle matching plate is a flat structure or a curved surface structure with a small curvature.

[0030] Figure 5 This is a partial schematic diagram of a sensor bracket assembly according to an embodiment of this application, as shown below. Figure 5 As shown, the included angle between the fixing ring 211 and the angle matching plate 212 is 8°. The core structure 22 includes: an angle plate matching structure 221, a shaping body 222, and a bracket sidewall 223. The angle plate matching structure 221 is used to match and assemble with the angle matching plate 212 in the bumper matching structure 21, and the shaping body 222 matches with the outer side of the bumper. The bracket sidewall 223 is mechanically fastened to the ultrasonic sensor 1.

[0031] Figure 6 This is a partial schematic diagram of another sensor bracket assembly according to an embodiment of this application, as shown below. Figure 6 As shown, the included angle between the fixing ring 211 and the angle matching plate 212 is 12°. The core structure 22 includes: an angle plate matching structure 221, a shaping body 222, and a bracket sidewall 223. The angle plate matching structure 221 is used to match and assemble with the angle matching plate 212 in the bumper matching structure 21, and the shaping body 222 matches with the outer side of the bumper. The bracket sidewall 223 is mechanically fastened to the ultrasonic sensor 1.

[0032] As can be seen, only one core structure is needed when used with a fixed ultrasonic sensor.

[0033] Will Figure 5 and Figure 6 The two sensor brackets shown can be seen when stacked together. Figure 7 As can be seen, the differences between the two cases of bumper matching structure 21 are small. The difference lies in the inconsistency of the tilt angle of the side wall of the angle matching plate 212-1 / 212-2, which is 8° vs 12°. Correspondingly, the bottom surface of the angle matching plate 212-1 / 212-2 also differs, which is also related to the difference in tilt angle.

[0034] Therefore, in actual mold making, only two molds for the two bumper matching structures 21 need to be made for the two sensor brackets. The difference between the two bumper matching structures 21 is small, and the difference in the mold mechanism is very small. The same mechanism is processed at the same time, saving procurement / design / drawing review time. Even when the product volume is small, one set of molds can be made, resulting in a significant cost reduction.

[0035] The detachable sensor bracket structure of this application embodiment includes a bumper matching structure and a core structure, with the core structure and bumper matching structure being assembled together. Different sensor bracket structures can use the same core structure and different bumper matching structures. Different bumper matching structures are relatively simple, the mold making is simple, and the mold cost is low. Therefore, this application can avoid making a mold for the entire bracket structure, but only making a mold for the bumper matching structure with slight differences, thereby reducing the complexity of mold making and thus reducing the cost of mold making.
