[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0030] Example 1
[0031] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a passenger car door lock opening and closing sound quality test tool, which includes a backing plate 1, a door lock frame 3 is welded to one side of the top of the backing plate 1 through a bracket, a door body 4 is hingedly installed at the rear end surface of the door lock frame 3, and a lock body that is locked with the door body 4 is installed on the door lock frame 3, and the door body 4 and the lock body are both existing mature technologies, so they are not described in detail;
[0032] A door closing assembly 5 is installed on the top of the pad 1, and the pushing end of the door closing assembly 5 is located on the side close to the door body 4. The door closing assembly 5 includes an arc-shaped bin 52. A movable channel 53 is opened on one side of the arc-shaped bin 52 close to the door body 4. A slide block 57 is installed in the movable channel 53 for internal limiting sliding. The side strips of the slide block 57 pass through the movable channel 53 and protrude from the inside of the arc-shaped bin 52. An engine bin 56 is welded at the open part of one side of the arc-shaped bin 52. An air cannon 510 is installed inside the engine bin 56. The slide block 57 is driven by the air cannon 510 to move and contact the door body 4, which can ensure that the force driving the slide block 57 to move is consistent each time, so that when each door is detected, the door closing operation is performed with one force, avoiding the deviation of detection when closing the door with different forces.
[0033] A rubber sheet 55 is bonded to the side strip of the sliding plate 57 and the side away from the engine compartment 56, and the thickness of the rubber sheet 55 is five centimeters. The setting of the rubber sheet 55 provides protection when the sliding plate 57 collides with the door body 4, and reduces the damage to the door body 4 when the buffer assembly 54 contacts the door body 4.
[0034] Two arc-shaped slide bars 59 are installed on one side of the inner wall of the arc-shaped bin 52 , and a second limiting groove for sliding with the arc-shaped slide bar 59 is provided on one side of the slide block 57 close to the arc-shaped slide bar 59 .
[0035] A buffer assembly 54 is installed inside the arc-shaped bin 52 at one end away from the machine bin 56 , and a sliding plate 57 is located in the middle of one end side inside the arc-shaped bin 52 and has a center hole 571 .
[0036] The door closing assembly 5 also includes two linear motors 51 installed on the top of the pad 1. The movable ends of the two linear motors 51 are fixedly installed with vertical columns 58, and the top ends of the two vertical columns 58 are respectively connected to the bottom of the arc bin 52 and the bottom of the machine bin 56. The two linear motors 51 drive the arc bin 52 to move left and right. When no detection is required, the arc bin 52 is moved to the side away from the door lock frame 3, so that the space between the door lock frame 3 and the door body 4 will be more spacious and obstacle-free, which is convenient for related operations.
[0037] During use, the door body 4 to be inspected is installed on the door lock frame 3, and then the door body 4 is opened at a certain angle, and the slide block 57 is moved to the side close to the engine compartment 56. The air cannon 510 converts the air pressure energy into air jet kinetic energy, generating a strong impact force to spray the slide block 57. When the impact force pushes the slide block 57 to move in the direction of the buffer assembly 54, the slide block 57 will contact the door body 4 during the movement, and push the door body 4 to realize the closing operation of the door body 4.
[0038] Example 2
[0039] Reference Figure 1-6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0040] The buffer assembly 54 includes an arc column 541 welded to the end of the arc bin 52 away from the machine bin 56, an extrusion block 543 is slidably installed inside the arc column 541, a blocking ring is sleeved on the head end of the outer wall of the arc column 541, and the blocking ring is used to block the extrusion block 543, and a spring 542 is sleeved on the outer wall of the arc column 541 and located on the side of the extrusion block 543 away from the blocking ring. When the slide block 57 moves inside the arc bin 52, the arc column 541 passes through the inside of the center hole 571, and then the slide block 57 will collide with the limiting slide groove 544, and the slide block 57 pushes the extrusion block 543 to move in the direction of the spring 542, and the limiting slide groove 544 compresses the spring 542. Under the elastic action of the spring 542, the slide block 57 is blocked and buffered to prevent the slide block 57 from moving in the direction of the door body 4 when subjected to force.
[0041] The outer diameter of the blocking ring is smaller than the diameter of the central hole 571 . Two sliding grooves 544 for sliding with the arcuate slide bar 59 are formed on one side of the extrusion block 543 close to the arcuate slide bar 59 .
[0042] Microphones 31 are embedded and installed on both sides of the end surface of the door lock frame 3 away from the door body 4. One of the two microphones 31 is located at the hinged installation position of the door body 4 and the door lock frame 3, and the other is located at the lock body of the door body 4 and the door lock frame 3. Loudspeakers 32 are installed at the lower positions on both sides of the end surface of the door lock frame 3 away from the door body 4, and the microphones 31 and the loudspeakers 32 on the same side are connected by wires. The sound generated when the door body 4 is closed is collected by the microphone 31 and amplified and played by the loudspeaker 32, which helps the staff to hear the sound clearly.
[0043] Three triangular brackets 2 are welded on the top of the pad 1 and on the end surface of the door lock frame 3 on one side away from the door body 4, and the triangular brackets 2 are welded to the door lock frame 3 on the side close to the door lock frame 3. The triangular brackets 2 support the door lock frame 3 from the side of the door lock frame 3 away from the door body 4. When the door body 4 and the door lock frame 3 are closed and cause an impact on the door lock frame 3, the triangular brackets 2 support the door lock frame 3 to ensure the stability of the door lock frame 3 when it is impacted.
[0044] During use, when the slide block 57 moves inside the arc-shaped bin 52, the arc column 541 passes through the center hole 571, and then the slide block 57 will hit the limiting slide groove 544, and the push-extrusion block 543 of the slide block 57 moves in the direction of the spring 542, and the limiting slide groove 544 compresses the spring 542. Under the elastic action of the spring 542, the slide block 57 is blocked and buffered.
[0045] The remaining structures are the same as those of Example 1.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
