Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic sensors, and in particular to a sensor device and a car door. Background Art

[0002] Most traditional ultrasonic sensors cannot penetrate metal because the metal will resonate with the aluminum head of the sensor, causing noise and making it impossible to work properly. Generally, it is necessary to make holes in the door panels and bumpers to expose the aluminum head in order to work properly, but this affects the overall appearance.

[0003] By installing a coupling piece between the door panel and the sensor aluminum head, the sensor aluminum head is attached to the door panel through the coupling piece. The coupling piece effectively transmits the sound energy generated by the sensor aluminum head so that the sound energy can penetrate the door panel. A certain holding force needs to be applied to the sensor so that it can effectively contact the door panel for a long time.

[0004] However, due to the different shapes of car doors and the small space inside the car door, the construction workers can only use one hand to operate the ultrasonic sensor inside the car door. The installation is cumbersome. If the installation is not done properly, the aluminum head coupling plate of the sensor may not fit well on the door panel, and a gap will be created between the door panel and the coupling plate, resulting in a cavity and functional failure.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0047] like Figure 1 As shown, the sensor device provided in this embodiment includes: a knob assembly 100 and a sensor body 200; the knob assembly 100 is provided with a receiving groove 111, and a clamping portion 112 is provided at the opening of the receiving groove 111, and the clamping portion 112 can abut against the sensor body 200 to fix the sensor body 200 in the receiving groove 111; the knob assembly 100 is configured to be rotatable relative to the sensor body 200 so that the sensor body 200 can extend out of the receiving groove 111.

[0048] Specifically, a receiving groove 111 is opened on the knob assembly 100, and a snap-fitting portion 112 is arranged at the opening groove wall of the receiving groove 111, and a snap-fitting protrusion is arranged on the sensor body 200 corresponding to the snap-fitting portion 112. When the sensor body 200 needs to be installed, the sensor body 200 is first extended into the receiving groove 111 so that the snap-fitting protrusion is placed in the receiving groove 111, and the knob assembly 100 is rotated to make the snap-fitting portion 112 rotate relative to the sensor body 200. The snap-fitting portion 112 contacts the snap-fitting protrusion, and the snap-fitting portion 112 limits the snap-fitting protrusion from moving in the direction of extending out of the receiving groove 111, thereby fixing the sensor body 200 in the receiving groove 111.

[0049] The sensor device provided in this embodiment includes: a knob assembly 100 and a sensor body 200; the knob assembly 100 is provided with a receiving groove 111, and a clamping portion 112 is provided at the opening of the receiving groove 111, and the clamping portion 112 can abut against the sensor body 200 to fix the sensor body 200 in the receiving groove 111; the knob assembly 100 is configured to be rotatable relative to the sensor body 200 so that the sensor body 200 can extend out of the receiving groove 111. By providing the clamping portion 112 on the knob assembly 100, the sensor body 200 is clamped in the receiving groove 111 by the clamping portion 112. After the staff determines the installation position of the sensor body 200, they only need to rotate the knob assembly 100 to disconnect the contact between the clamping portion 112 and the sensor body 200, and the sensor body 200 extends out of the receiving groove 111 to complete the installation of the sensor, thereby alleviating the technical problems existing in the prior art that the sensor installation is cumbersome, the installation is prone to be incomplete, and the normal use of the sensor is affected.

[0050] On the basis of the above embodiments, in an optional implementation manner, the knob assembly 100 in the sensor device provided in this embodiment includes an outer knob 110 and an inner knob 120; the inner knob 120 is arranged in a receiving groove 111 on the outer knob 110, and the inner knob 120 is rotatably connected to the outer knob 110, and there is an elastic force between the inner knob 120 and the sensor body 200, and the elastic force is used to make the sensor body 200 have a movement tendency to extend out of the receiving groove 111.

[0051] Specifically, a receiving groove 111 is provided on the outer knob 110, and a clamping portion 112 is provided at the groove wall port position of the outer knob 110. The diameter of the outer knob 110 is larger than the diameter of the inner knob 120. The inner knob 120 is provided in the receiving groove 111. The inner knob 120 is rotatably connected to the outer knob 110. The inner knob 120 and the outer knob 110 can rotate relative to each other. The inner knob 120 is connected to the sensor body 200. When the sensor body 200 is installed in the receiving groove 111, there is an elastic force between the inner knob 120 and the sensor body 200. The outer knob 110 is rotated to release the abutment between the clamping portion 112 and the sensor body 200. Since the inner knob 120 is fixed in the receiving groove 111, the elastic force causes the sensor body 200 to pop out of the receiving groove 111, and the sensor body 200 is installed in place.

[0052] In addition, the inner knob 120 and the outer knob 110 are locked together by a screw, but the screw does not lock the inner knob 120 , so that the inner knob 120 and the outer knob 110 can rotate relative to each other.

[0053] In an optional embodiment, an elastic member 300 is arranged between the inner knob 120 and the sensor body 200, and the elastic member 300 has a compressed state and a natural state; when the elastic member 300 is in the compressed state, the sensor body 200 abuts against the clamping portion 112, and the sensor body 200 is located in the accommodating groove 111; when the elastic member 300 is in the natural state, the sensor body 200 extends out of the accommodating groove 111.

[0054] Specifically, the elastic member 300 is specifically configured as a spring, and annular fixing columns are provided on the inner knob 120 and the sensor body 200. The two ends of the spring are respectively fixed in the fixing columns on the inner knob 120 and the sensor body 200, thereby connecting the inner knob 120 and the sensor body 200. When the sensor body 200 extends into the accommodating groove 111, the sensor body 200 contacts the clamping portion 112 on the outer knob 110. The elastic member 300 is in a compressed state and has elastic force. The outer knob 110 is rotated to disconnect the contact between the clamping portion 112 and the sensor body 200. The elastic force of the elastic member 300 pushes the sensor body 200 out of the accommodating groove 111, and the elastic member 300 returns to a natural state.

[0055] It should be noted that the elastic member 300 in a natural state still has elastic force to support the sensor body 200 and to make the probe of the sensor body 200 closely attached to the coupling sheet 210 .

[0056] In an optional embodiment, the knob assembly 100 further includes a flexible member 400 ; the flexible member 400 is sandwiched between the outer knob 110 and the inner knob 120 .

[0057] Specifically, a flexible member 400 is provided between the inner knob 120 and the outer knob 110. The flexible member 400 is specifically provided as a silicone pad. The silicone pad has a certain flexibility and can effectively and evenly bear the force. Figure 2 , Figure 3 As shown, the flexible component 400 cooperates with the elastic component 300 so that the coupling piece 210 on the aluminum head of the sensor body 200 can effectively fit the door panel on any door or trim shape, and no matter what angle the sensor is placed at according to the shape of the door or trim, the inner button structure is designed to move in a limited space, and the metal door panel or trim surface is subjected to normal force, so that the force acting on the coupling piece 210 on the aluminum head surface of the sensor body 200 is more uniform and the function is more stable.

[0058] The sensor device provided in this embodiment rotates the outer knob 110 relative to the inner knob 120, so that the sensor body 200 extends out of the accommodating groove 111 in the outer knob 110 due to the elastic force of the elastic component 300, and the sensor body 200 is tightly attached to the door panel or trim panel, which is more convenient to install.

[0059] On the basis of the above embodiments, in an optional implementation manner, the sensor device provided in this embodiment also includes a bracket base 500; a fixing groove 510 is provided on the bracket base 500, and a protrusion 113 is provided on the outer surface of the outer knob 110, and the protrusion 113 extends into the fixing groove 510, and the protrusion 113 can move along the fixing groove 510 so that the outer knob 110 can rotate relative to the bracket base 500.

[0060] Specifically, a fixing groove 510 is opened on the bracket base 500, and the cross-sectional shape of the fixing groove 510 is L-shaped. The protrusion 113 on the outer surface of the outer knob 110 extends into the fixing groove 510. The protrusion 113 moves along the fixing groove 510, and when it moves to the position where the fixing groove 510 limits the vertical movement of the protrusion 113, the outer knob 110 fits on the bracket base 500.

[0061] In an optional embodiment, a limiting opening 520 is provided on the bracket base 500 ; the limiting opening 520 can abut against the sensor body 200 to limit the rotation of the sensor body 200 .

[0062] Specifically, when the outer knob 110 is installed with the bracket base 500, the sensor body 200 is located at the position of the limit opening 520 of the bracket base 500. During the rotation of the outer knob 110 relative to the bracket base 500, the sensor body 200 abuts against the limit opening 520, and the sensor body 200 cannot rotate with the rotation of the outer knob 110. The outer knob 110 rotates relative to the sensor body 200. Figure 5 As shown, the abutment between the snap-fit ​​portion 112 on the outer knob 110 and the sensor body 200 is disconnected, the elastic member 300 pushes the sensor body 200 out of the accommodating groove 111, and the probe on the sensor body 200 moves toward the installation position. Finally, the probe on the sensor body 200 and the coupling plate 210 are tightly attached to the metal door panel or trim panel, which is convenient for installation. The staff only needs one hand to complete the installation.

[0063] like Figure 4 As shown, in an optional embodiment, a fixing plate 600 is disposed on the outer surface of the bracket base 500 , and a plurality of raised blocks arranged in an array are disposed on the fixing plate 600 .

[0064] Specifically, a fixing plate 600 is arranged on the outer surface of the bracket base 500, and the fixing plate 600 can abut against the metal door panel or decorative panel to determine the installation position of the probe of the sensor body 200, and an array of raised blocks are provided on the fixing plate 600 to divide the fixing plate 600, thereby improving the softness of the fixing plate 600 and maximizing the strength.

[0065] In an optional embodiment, a sponge 700 is provided on a side of the fixing plate 600 away from the bracket base 500 .

[0066] Specifically, the working principle of ultrasound is that the ceramic plate vibrates the aluminum head to generate ultrasound, but the ultrasound itself is easily affected by external factors. For example, if there are too many metal parts around it or they are too close, it will cause false alarms. In order to solve this problem, a sponge 700 is placed on the bracket base 500 so that it can effectively isolate external influences. In order to effectively penetrate the metal plate 900, it is also necessary to integrate the frequency between the aluminum head and the metal door panel through the coupling plate 210 attached to the sensor aluminum head so that the ultrasound can effectively penetrate the door panel.

[0067] In an optional embodiment, in order to fix the fixing plate 600 on the metal door panel or the decorative panel, an adhesive component 800 is provided on a side of the fixing plate 600 away from the bracket base 500 , and the adhesive component 800 is sleeved outside the sponge 700 .

[0068] Specifically, the adhesive component 800 is specifically configured as a 3M adhesive pad, which has adhesiveness and is easy to install.

[0069] The automobile door provided in this embodiment includes a sensor device.

[0070] Since the technical effect of the automobile door provided by this embodiment is the same as the technical effect of the above-mentioned sensor device, it will not be repeated here.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
