Description

Technical Field

[0001] The invention relates to the technical field of distance measurement and detection, in particular to a trunk based on a TOF object detection distance measurement sensor. Background Art

[0002] In today's cars, the trunk undoubtedly plays a vital role in storage. In order to greatly improve the convenience and safety of the trunk, TOF detection and ranging sensors came into being. This advanced sensor can accurately sense various conditions outside the trunk by accurately emitting light pulses and accurately measuring their flight time. In some high-end models, the sensor has shown powerful functions. It can assist the automatic opening and closing of the trunk. For example, when the sensor keenly detects that the owner is approaching the vehicle, it will quickly and automatically trigger the trunk to open, providing a convenient user experience for the owner; and in the process of closing the trunk, if the sensor detects that there is an object blocking it, it will immediately suspend the closing action to effectively prevent people from being pinched or items from being damaged. In addition, the TOF detection and ranging sensor also has the ability to sense the outside through the trunk under certain conditions, such as being able to detect whether there are obstacles behind the vehicle that affect the opening of the trunk. This function further improves the intelligence level and safety of the car.

[0003] However, the existing TOF object detection and ranging sensors are usually installed inside the trunk of a car. During their use, bolts are often used for auxiliary installation, and they are hidden inside the trunk. In this way, when the sensor is damaged, it is obviously impossible to quickly disassemble and repair it. Usually, the disassembly and replacement process requires professional personnel to operate, which undoubtedly leads to high subsequent maintenance and replacement costs during overall use, and the disassembly and replacement process is extremely cumbersome and inconvenient. Moreover, during their use, the sensor's redundant wire structure lacks a winding wiring device, and its redundant wires are often bonded and wrapped around the inside of the trunk with tape, which makes the overall wiring appear rather messy. At the same time, the glue used for tape wiring has a limited service life. When the glue is nearing its expiration date, it is very easy for the wire to fall off, causing great trouble and inconvenience to users. Therefore, it is urgent to improve the existing TOF object detection and ranging sensors. Summary of the invention

[0028] The card-mounting mechanism 6 comprises a mounting rail 61 and a card frame 62. The mounting rail 61 is fixedly mounted on the upper end of the rear side of the box cover 3. Both ends of the mounting rail 61 are fixedly mounted with card-mounting components 63. The card frame 62 is fixedly mounted on both sides of the sensor housing 5. The ends of the card-mounting components 63 are inserted into the interior of the card frame 62.

[0029] See also Figure 1-Figure 6 The overall cross-sectional shape of the box cover 3 is L-shaped, and the external corners of the box cover 3 are all set to arc shapes. The clamping assembly 63 includes a limit spring 631, and the limit spring 631 is fixedly installed at both ends of the mounting rail frame 61. The outer end of the limit spring 631 is fixedly installed with a movable frame 632, and the movable frame 632 is slidably connected to the two ends of the mounting rail frame 61.

The side plate 71 is fixedly connected to the sensor housing 5, which provides a winding mechanism 7. The locking cam 75 is in a state of being pressed downwardly, so that the locking cam 75 can be locked to the locking cam 70 when the locking cam 70 is unlocked and the locking cam 70 is locked.

[0032] The working principle of the present invention is as follows: by setting the card installation mechanism 6, the present device can play a great advantage during actual use. The TOF object detection and ranging sensor and the projection sensor inside the sensor housing 5 cooperate with each other to assist in all-round and accurate detection of the rear of the vehicle. Moreover, they work in coordination with the system inside the vehicle body 1 to efficiently realize the function of automatically opening and closing the trunk 2 of the vehicle, bringing great convenience to the user. When the sensor needs to be repaired, the operation is extremely convenient. The user can manually adjust the armrest 643 to drive the linkage guide block 642 to rotate. During the rotation of the linkage guide block 642, its state will change from vertical rotation to horizontal rotation. The linkage guide block 642 is in a narrow and long elliptical shape. When it is in a horizontal state, it can forcefully squeeze and open the inner end of the linkage guide plate 641. As the linkage guide plate 641 is opened, it will further push the movable frame 632 to slide smoothly on the inner side of the mounting rail frame 61. The linkage guide plate 641 drives the movable rail frame to move, thereby pushing the limit block 6 on the limit frame 633. 34 is separated from the card frame 62. At this time, the sensor housing 5 can be easily removed from the box cover 3. Then, the plug on the guide is pulled out from the socket of the wire 9 of the vehicle body 1, and the probe of the sensor housing 5 is pulled out from the inner side of the reserved hole 4. In this way, the whole disassembly process is completed. If the sensor needs to be reinstalled, the sensor housing 5 can be taken out first, and the wire 9 can be connected through the connector and the connector. Then, the sensor housing 5 can be pushed between the limit blocks 634. In this process, the guide block 65 The guide limit block 634 is squeezed on the inclined surface of the sensor, so that the limit block 634 can be stretched to move outward. When the limit block 634 contacts the card frame 62, the limit spring 631 is reset, and the movable frame 632 is pulled to drive the limit frame 633 to move inward, so that the limit block 634 is inserted into the inner side of the card frame 62. At this time, the installation of the sensor as a whole is successfully completed. It can be seen that the sensor as a whole in the device is easy to disassemble and repair quickly, which can further improve the convenience of subsequent use of the device as a whole and greatly reduce its use cost.

[0033] The wire-reeling mechanism 7 is provided so that the device exhibits excellent performance during use. During use, the rotating disk 74 can be twisted to drive the reel 75 to rotate. At this time, the torsion spring 73 will be in a compressed state. Then, the wire 9 is passed through the inner side of the threading groove 76 of the reel 75. Then, the connector of the wire 9 and the connector on the vehicle body 1 are plugged into each other. At this time, the reel 75 and the rotating disk 74 are released, and the torsion spring 73 is reset. The reset of the torsion spring 73 can drive the reel 75 to rotate. The reel 75 rotates to reel the wire 9. When the wire 9 needs to be pulled out and extended, it is only necessary to gently pull the wire 9, which can cause the winding shaft 75 and the turntable 74 to rotate in the opposite direction, thereby driving the torsion spring 73 to contract again. Since the torsion spring 73 provides elastic force at all times, it can always rewind the excess wire 9, so that the wire 9 can be in a tight state. In this way, the excess wire 9 will not be arranged in a messy manner, which can greatly improve the stability and neatness of the line as a whole, bring great convenience to users, and make the use of the device more convenient and efficient.
