Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The kick sensor 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0044] like Figure 1 As shown, the kick sensor 10 according to the embodiment of the present utility model includes an electronic control unit 1 and an inductive antenna assembly 2 .

[0045] Specifically, refer to the attached Figure 1 and attached Figure 3 As shown, the kick sensor 10 is suitable for being arranged on the front surface of the rear bumper 20 and located at the rear side of the wheel 200, the electronic control unit 1 is suitable for being arranged on the rear bumper 20 of the vehicle, and the sensing antenna assembly 2 is suitable for being arranged on the rear bumper 20 and is two, and the two sensing antenna assemblies 2 are suitable for being respectively located on the electronic control unit 1 along the left and right directions (such as Figure 1 On both sides of the induction antenna assembly 2 as shown, the induction antenna assembly 2 is electrically connected to the electronic control unit 1.

[0046] It can be understood that when the sensing antenna assembly 2 detects a change in capacitance, it can transmit the detected change time and capacitance change amount to the electronic control unit 1. The electronic control unit 1 determines whether it is a valid kicking action by calculating and processing the capacitance change amount. When the electronic control unit 1 determines that it is a valid kicking action, it will send a kick trigger instruction to the BCM (body controller) to realize the opening, hovering or closing of the vehicle tailgate, which greatly improves the convenience and comfort and improves the user experience; when the electronic control unit 1 determines that it is an invalid kicking action, it will not send relevant instructions to the BCM, which can avoid false triggering caused by people walking near the rear bumper 20 of the vehicle or small animals passing through the bottom of the vehicle, further improving the user experience.

[0047] Preferably, the kick sensor 10 of the present invention is a capacitive kick sensor 10, which has the advantages of simple structure, low cost, sensitive sensing, etc., and can reduce costs and increase efficiency.

[0048] It can be understood that the two sensing antenna components 2 each serve as a signal input source separately, and can simultaneously detect the capacitance changes on the left and right sides of the electronic control unit 1. Regardless of whether the user kicks on the left side of the electronic control unit 1 or on the right side of the electronic control unit 1, the kicking action can be effectively sensed, thereby expanding the sensing range of the sensing antenna component 2, improving the perception accuracy of the sensing antenna component 2, greatly improving the user experience, and being able to meet the layout requirements of different vehicle models, thereby improving the compatibility of the kick sensor 10.

[0049] It should be noted that if Figure 1 As shown, when the electronic control unit 1 is provided with sensing antenna components 2 on both sides along the left and right directions, the two sensing antenna components 2 can detect the left and right sides of the electronic control unit 1 respectively, and the electronic control unit 1 can analyze and process the kicking action signals received by the two sensing exploration components separately, so that any side of the sensing area on the left and right sides senses the capacitance change, and the electronic control unit 1 can calculate and process the capacitance change. After determining that it is a valid kicking action, the electronic control unit 1 will send a kicking trigger instruction to the BCM. In addition, since the electronic control unit 1 independently processes and analyzes the sensing signals on the left and right sides, the arrangement of the two sensing antenna components 2 can be adjusted according to the specific structure on both sides of the vehicle rear bumper 20, and the kicking algorithm can also optimize the kicking function according to the calibration conditions on the left and right sides.

[0050] Alternatively, if Figure 1As shown, the electronic control unit 1 may be arranged in the middle area of ​​the rear bumper 20 along the left-right direction of the vehicle, in which case the lengths of the two sensing antenna assemblies 2 in the left-right direction are substantially the same; or the electronic control unit 1 may be arranged on one side of the center line of the rear bumper 20 in the left-right direction, in which case the lengths of the two sensing antenna assemblies 2 in the left-right direction are different, which can be reasonably adjusted according to the distance between the electronic control unit 1 and the two ends of the rear bumper 20 in the length direction.

[0051] According to the kick sensor 10 of the embodiment of the utility model, the kick sensor 10 includes an electronic control unit 1 and a sensing antenna assembly 2. The electronic control unit 1 is arranged on the rear bumper 20 of the vehicle. The sensing antenna assembly 2 is arranged on the rear bumper 20 and there are two of them. The two sensing antenna assemblies 2 are respectively located on both sides of the electronic control unit 1 along the left and right directions. The sensing antenna assembly 2 is electrically connected to the electronic control unit 1, and can detect the capacitance changes on the left and right sides of the electronic control unit 1, expand the sensing range of the sensing antenna assembly 2, accurately sense the user's kicking action, realize the opening, hovering or closing action of the vehicle tailgate, and greatly improve the user's experience.

[0052] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 4 As shown, the sensing antenna assembly 2 includes a first sensing antenna 21 and a second sensing antenna 22, one end of the first sensing antenna 21 in the length direction and one end of the second sensing antenna 22 in the length direction are both electrically connected to the electronic control unit 1, the other end of the first sensing antenna 21 in the length direction and the other end of the second sensing antenna 22 in the length direction both extend in the left-right direction in the direction away from the electronic control unit 1, at least a portion of the first sensing antenna 21 and at least a portion of the second sensing antenna 22 are spaced apart, and by differentially arranging the first sensing antenna 21 and the second sensing antenna 22, the user's kicking action can be sensed from two spaced-apart locations, and only when the first sensing antenna 21 and the second sensing antenna 22 simultaneously sense a capacitance change, and the change time and capacitance change value both meet the conditions set by the algorithm, will it be determined as a valid kicking action, which can further reduce the situation of false triggering, improve the perception accuracy of the kick sensor 10, realize the normal opening, hovering or closing action of the vehicle tailgate, improve the user's use experience, and improve the user's comfort and satisfaction.

[0053] In a further embodiment of the present invention, refer to the attached Figure 1 and attached Figure 4As shown, the first sensing antenna 21 has a first sensing segment 211, and the second sensing antenna 22 has a second sensing segment 221. The first sensing segment 211 and the second sensing segment 221 both extend in the left-right direction and are spaced apart, thereby ensuring the sensing range of the first sensing antenna 21 and the second sensing antenna 22 in the left-right direction and ensuring the sensing range of the sensing antenna assembly 2.

[0054] In a further embodiment of the present invention, refer to the attached Figure 3 As shown, along the front-to-back direction (such as Figure 3 As shown in the figure, the first sensing segment 211 and the second sensing segment 221 are arranged at intervals, which can match the kicking action of the user. When the user makes a kicking action, the first sensing segment 211 and the second sensing segment 221 can be used to detect the user's calf and instep or two places of the calf spaced along the length direction respectively. Only when the first sensing segment 211 and the second sensing segment 221 sense the capacitance change at the same time, and the change time and the capacitance change value meet the conditions set by the algorithm, will it be determined as a valid kicking action, which can further reduce the situation of false triggering, improve the perception accuracy of the kick sensor 10, realize the normal opening, hovering or closing action of the vehicle tailgate, improve the user experience, and improve the user's comfort and satisfaction.

[0055] Further, see Attachment Figure 3 As shown, the distance between the first sensing segment 211 and the second sensing segment 221 is a, and satisfies: 50mm≤a≤90mm. It can be understood that when the user makes a kicking action, the first sensing segment 211 can be used to detect the user's calf part, and the second sensing segment 221 can be used to detect the user's instep part. By limiting 50mm≤a≤90mm, it can match the user's kicking action, so that the first sensing segment 211 and the second sensing segment 221 can both normally sense the capacitance change when the user kicks, thereby improving the sensing effect of the kicking sensor 10 for the kicking action, realizing the normal opening, hovering or closing action of the vehicle tailgate, improving the user's use experience, and improving the user's comfort and satisfaction. For example, the distance a between the first sensing segment 211 and the second sensing segment 221 in the front-to-back direction can be 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm or 90mm.

[0056] In a further embodiment of the present invention, refer to the attached Figure 3As shown, along the up and down direction, the first sensing segment 211 and the second sensing segment 221 are spaced apart, which can match the user's kicking action. When the user makes a kicking action, the first sensing segment 211 and the second sensing segment 221 can be used to detect the user's calf and instep or two places of the calf spaced apart along the length direction respectively. Only when the first sensing segment 211 and the second sensing segment 221 sense the capacitance change at the same time, and the change time and the capacitance change value meet the conditions set by the algorithm, will it be determined as a valid kicking action, which can further reduce the situation of false triggering, improve the perception accuracy of the kick sensor 10, realize the normal opening, hovering or closing action of the vehicle tailgate, improve the user experience, and improve the user's comfort and satisfaction.

[0057] Further, see Attachment Figure 3 As shown, the distance between the first sensing segment 211 and the second sensing segment 221 is b, and satisfies: 50mm≤b≤90mm. It can be understood that when the user makes a kicking action, the first sensing segment 211 can be used to detect the user's calf part, and the second sensing segment 221 can be used to detect the user's instep part. By limiting 50mm≤b≤90mm, it can match the user's kicking action, so that the first sensing segment 211 and the second sensing segment 221 can both normally sense the capacitance change when the user kicks, thereby improving the sensing effect of the kicking sensor 10 for the kicking action, realizing the normal opening, hovering or closing action of the vehicle tailgate, improving the user's use experience, and improving the user's comfort and satisfaction. For example, the distance b between the first sensing segment 211 and the second sensing segment 221 in the vertical direction can be 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm or 90mm.

[0058] In a further embodiment of the present invention, refer to the attached Figure 3 As shown, the first sensing segment 211 is located behind the second sensing segment 221 and above the second sensing segment 221, and can match the user's kicking action. When the user makes a kicking action, the first sensing segment 211 and the second sensing segment 221 can be used to detect the user's calf and instep or two places of the calf spaced along the length direction respectively. Only when the first sensing segment 211 and the second sensing segment 221 sense the capacitance change at the same time, and the change time and the capacitance change value meet the conditions set by the algorithm, will it be determined as a valid kicking action, which can further reduce the situation of false triggering, improve the perception accuracy of the kick sensor 10, realize the normal opening, hovering or closing action of the vehicle tailgate, improve the user experience, and improve the user's comfort and satisfaction.

[0059] Further, see Attachment Figure 3As shown, on a cross section perpendicular to the left and right directions, the angle between the line connecting the first sensing segment 211 and the second sensing segment 221 and the horizontal line is c, and satisfies: c≤40°. It can be understood that when the user makes a kicking action, the first sensing segment 211 can be used to detect the user's calf part, and the second sensing segment 221 can be used to detect the user's instep part. By defining: c≤40°, it can match the user's kicking action, so that the first sensing segment 211 and the second sensing segment 221 can both normally sense the capacitance change when the user kicks, thereby improving the sensing effect of the kick sensor 10 for the kicking action, realizing the normal opening, hovering or closing action of the vehicle tailgate, improving the user's use experience, and improving the user's comfort and satisfaction. For example, the angle c between the line connecting the first sensing segment 211 and the second sensing segment 221 and the horizontal line can be 30°, 33°, 35°, 38° or 40°.

[0060] In a specific example, see the attached Figure 1 and attached Figure 3 As shown, the rear bumper 20 includes a first plate 201 and a second plate 202. The first plate 201 extends in an up-down direction (eg Figure 3 The second plate 202 is connected to the lower end of the first plate 201. From top to bottom, the second plate 202 is inclined toward the front side of the vehicle. The electronic control unit 1 is fixed to the first plate 201 by fasteners. The first sensing segment 211 and the second sensing segment 221 are both fixed to the front surface of the second plate 202. The first sensing segment 211 is located behind the second sensing segment 221 and above the second sensing segment 221.

[0061] In a further embodiment of the present invention, refer to the attached Figure 4 As shown, the first sensing antenna 21 has a first connecting section 212, the first connecting section 212 is directly connected to the electronic control unit 1, and the first connecting section 212 and the first sensing section 211 are sealed and connected via a first plastic package, which can effectively protect the first sensing antenna 21 and prevent the first sensing antenna 21 from being damaged by the outside world, thereby improving the integrity rate and service life of the kick sensor 10.

[0062] Further, see Attachment Figure 4 As shown, the second sensing antenna 22 has a second connecting section 222, which is directly connected to the electronic control unit 1, and the second connecting section 222 is sealed and connected to the second sensing section 221 through a second plastic package, which can effectively protect the second sensing antenna 22 and prevent the second sensing antenna 22 from being damaged by the outside world, thereby improving the integrity rate and service life of the kick sensor 10.

[0063] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 4As shown, the kick sensor 10 further includes a mounting buckle 30, which is disposed on the rear bumper 20 and is used to fix the sensing antenna assembly 2. The mounting buckle 30 can constrain the direction of the sensing antenna assembly 2, and reasonably arrange the routing of the sensing antenna assembly 2 to avoid the messy routing of the kick sensor 10 and avoid affecting the maintenance and replacement of the rear bumper assembly 100. In a specific example, the mounting buckle 30 includes a main body and a tie part, the main body is bonded to the rear bumper 20, and the sensing antenna assembly 2 is inserted into the tie part to fix the sensing antenna assembly 2 on the rear bumper 20.

[0064] In a further embodiment of the present invention, refer to the attached Figure 1 and attached Figure 4 As shown, the mounting buckles 30 are multiple and are arranged at intervals along the extension direction of the sensing antenna assembly 2, which can improve the restraint and fixing effect of the mounting buckles 30 on the sensing antenna assembly 2, and avoid the internal clutter of the rear bumper assembly 100. For example, the mounting buckles 30 can be two, three, four, five, six, seven or eight and are arranged at intervals along the extension direction of the sensing antenna assembly 2. It should be noted that the sensing antenna assembly 2 includes a first sensing antenna 21 and a second sensing antenna 22, the first sensing antenna 21 includes a first sensing section 211 and a first connecting section 212, and the second sensing antenna 22 includes a second sensing section 221 and a second connecting section 222. The first sensing section 211 and the second sensing section 221 can be spaced apart in the up-down direction and the front-back direction by the restraint of the mounting buckles 30, and the first connecting section 212 and the second connecting section 222 can be inserted into the same mounting buckle 30 to facilitate the electrical connection between the sensing antenna assembly 2 and the electronic control unit 1.

The electronic control unit 1 is spaced apart from the trailer hook 40 in the front-to-rear direction and / or the up-and-down direction of the vehicle. The two sensing antenna assemblies 2 are respectively located on both sides of the trailer hook 40 along the left-to-right direction and are spaced apart from the trailer hook 40, so that the sensing antenna assembly 2 can avoid the trailer hook 40 and be arranged normally, thereby ensuring the sensing range of the kick sensor 10 and the user experience.
