Description

Technical Field

[0001] This invention relates to the field of automotive rearview mirror technology, specifically to an intelligent automotive rearview mirror mounting assembly. Background Technology

[0002] The rearview mirror is an important component of a car. It is installed on the windshield of the vehicle and is mainly used to provide drivers and passengers with information about the rear view of the vehicle so that they can observe the situation behind the vehicle in a timely and accurate manner. With the development of intelligent technology, the rearview mirror is no longer limited to the function of observing the rear of the vehicle. At present, some rearview mirrors have built-in circuit boards, which integrate processors, microphones, speakers, Bluetooth modules, audio processing modules, voice recognition and voice synthesis modules, reversing camera modules and power buttons, enabling hands-free voice interaction and calling functions without manual operation.

[0003] While intelligent design provides great convenience for drivers, the uncertainty of road conditions and the fact that current rearview mirrors are rigidly fixed to the windshield or roof of the car make the internal components of the rearview mirror susceptible to damage from severe vibrations. Furthermore, the rigid connection method makes replacement extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent automotive rearview mirror mounting assembly to solve the following technical problems: most existing rearview mirrors are installed in the vehicle through rigid connections, which can easily damage internal components during severe vibrations and are inconvenient to replace.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An intelligent automotive rearview mirror mounting assembly includes a connecting arm, a rearview mirror cover, and a mounting base fixed to the windshield of the vehicle. One end of the connecting arm is fixed with a ball joint, which is connected to the rearview mirror cover. The end of the connecting arm near the mounting base has a first fixing groove and two second fixing grooves, with the two second fixing grooves located on both sides of the first fixing groove. The mounting base near the connecting arm has two insert rods and a pressing block, with the two insert rods corresponding to the positions of the two second fixing grooves and the pressing block corresponding to the position of the first fixing groove. A first airbag is disposed in the first fixing groove. A communicating cavity is formed between the first fixing groove and the second fixing grooves, and a limiting mechanism is disposed in the communicating cavity for fixing the connecting arm and the mounting base.

[0007] As a further aspect of the present invention: the limiting mechanism includes a fixing block fixed inside the communicating cavity, a first communicating pipe connected to the fixing block, one end of the first communicating pipe communicating with a first airbag, a first spring connected to the side wall of the fixing block away from the first communicating pipe, a first piston block connected to one end of the first spring, a limiting rod fixed to the side wall of the first piston block, a limiting hole opened on the rod, and the size of the limiting rod matching the size of the limiting hole.

[0008] As a further aspect of the present invention: a second airbag is fixed in each of the two second fixing slots. The second airbag is annular and sleeved on the outside of the insertion rod. A second connecting pipe is connected to the second airbag, and one end of the second connecting pipe is connected to the first airbag.

[0009] As a further aspect of the present invention: the first airbag is also connected to an inflation / deflation tube, one end of which extends through the connecting arm to the outside, and the end of the inflation / deflation tube away from the first airbag is threaded with a sealing plug.

[0010] As a further embodiment of the present invention: the rearview mirror cover is composed of a lower cover, an upper cover and a base, the upper cover is snapped onto the lower cover, the base is fixed onto the lower cover, an interior rearview mirror is mounted on the base, and multiple buffer pads are also provided on the lower cover.

[0011] As a further aspect of the present invention: a ball joint is provided between the lower cover and the upper cover, the ball joint is snapped into the ball joint, and a USB structure is also provided on one side of the lower cover.

[0012] As a further aspect of the present invention: a third airbag is provided at the top and bottom of the side wall of the rearview mirror cover, and the third airbag is a strip-shaped structure.

[0013] As a further embodiment of the present invention: symmetrically fixed blocks are provided on the mounting base, and slots are provided on the blocks; fixed rods are fixed on both sides of the connecting arm, and sleeves are fixed to one end of each fixed rod; ventilation tubes are connected to both third airbags, and one end of each ventilation tube is connected to one sleeve; a second spring is connected to the inner wall of the sleeve, and a second piston block is connected to one end of the second spring; a locking rod is fixed to the side wall of the second piston block, and one end of the locking rod penetrates the side wall of the sleeve, and the size of the locking rod matches the slot.

[0014] The beneficial effects of this invention are:

[0015] The present invention provides a first fixing groove and a second fixing groove on the connecting arm, which, together with the insertion rod, pressing block and limiting mechanism on the mounting base, can easily fix the connecting arm to the mounting base, thereby facilitating the installation of the rearview mirror and making it easy to disassemble and replace. In addition, the limiting mechanism prevents the connecting arm from detaching from the mounting base and allows it to move slightly along the limiting rod, thereby buffering vibration and reducing the impact of vibration on the internal components of the interior rearview mirror.

[0016] The present invention provides a second airbag, which is located in a second fixing groove. When the connecting arm moves slightly due to vibration, the second airbag buffers it and prevents the connecting arm from colliding with the plug rod, thereby further improving the protective effect.

[0017] The present invention improves the driver's comfort when adjusting the interior rearview mirror by incorporating a third airbag on the rearview mirror cover.

[0018] This invention incorporates a vent pipe, sleeve, locking rod, and locking block. Since the connecting arm and mounting base are not fixedly connected, to prevent the connecting arm from moving and affecting the adjustment of the interior rearview mirror, the locking rod automatically inserts into the locking block's slot during adjustment to fix the connecting arm, thereby ensuring the stability of the connecting arm during adjustment.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-5 As shown, this invention is an intelligent automotive rearview mirror mounting assembly, including a connecting arm 1, a rearview mirror cover 2, and a mounting base 4 fixed to the windshield of the vehicle. One end of the connecting arm 1 is fixed with a ball joint 3, which connects to the rearview mirror cover 2. The end of the connecting arm 1 near the mounting base 4 has a first fixing groove 101 and two second fixing grooves 108, located on either side of the first fixing groove 101. The mounting base 4 near the connecting arm 1 has two insert rods 401 and a pressing block 403, and the two insert rods 401 are connected to the two second fixing grooves 403. The positions of the groove 108 and the extrusion block 403 correspond to the positions of the first fixing groove 101. The first fixing groove 101 is provided with a first airbag 102. A connecting cavity 103 is provided between the first fixing groove 101 and the second fixing groove 108. A limiting mechanism is provided in the connecting cavity 103 for fixing the connecting arm 1 and the mounting base 4. During installation, the connecting arm 1 is brought close to the mounting base 4, the two insert rods 401 are inserted into the second fixing groove 108, and the extrusion block 403 enters the first fixing groove 101. With the help of the limiting mechanism, the connecting arm 1 and the mounting base 4 are fixed, and the installation is completed.

[0032] See Figure 5The limiting mechanism includes a fixing block 104 fixed inside the communicating cavity 103. A first communicating pipe 105 is connected to the fixing block 104. One end of the first communicating pipe 105 is connected to the first airbag 102. A first spring 109 is connected to the side wall of the fixing block 104 away from the first communicating pipe 105. One end of the first spring 109 is connected to a first piston block 106. A limiting rod 107 is fixed to the side wall of the first piston block 106. A limiting hole 402 is opened on the insertion rod 401. The limiting rod 107 and the limiting hole 402 are matched in size. When the extrusion block 403 enters the first fixing groove 101, it will extrude the first airbag 102. The gas inside the airbag 102 is discharged through the first connecting pipe 105, which then pushes the first piston block 106 and the limiting rod 107 to move, and stretches the first spring 109. The limiting rod 107 gradually approaches the insertion rod 401 and abuts against the insertion rod 401 until the connecting arm 1 contacts the mounting base 4. The limiting rod 107 is inserted into the limiting hole 402, which fixes the connecting arm 1 to the mounting base 4 and completes the installation. Then the rearview mirror cover 2 is connected to the ball head 3. The connecting arm 1 cannot be detached from the mounting base 4, but it can move slightly along the limiting rod 107. During vibration, it buffers the impact force and reduces damage to the internal electronic components.

[0033] See Figure 3 Each of the two second fixing slots 108 has a second airbag 111 fixed inside. The second airbag 111 is a ring structure sleeved on the outside of the insertion rod 401. The second airbag 111 is connected to a second connecting pipe 110, and one end of the second connecting pipe 110 is connected to the first airbag 102. The second airbag 111 is installed in the second fixing slot 108. Some of the gas in the first airbag 102 enters the second airbag 111 through the second connecting pipe 110. When the connecting arm 1 moves slightly, the second airbag 111 can prevent the connecting arm 1 from colliding with the insertion rod 401, thereby further improving the protective effect.

[0034] See Figure 2-3 The first airbag 102 is also connected to an inflation / deflation tube 112. One end of the inflation / deflation tube 112 extends through the connecting arm 1 to the outside, and the end of the inflation / deflation tube 112 away from the first airbag 102 is threaded with a sealing plug. The first airbag 102 is inflated or deflated using the inflation / deflation tube 112. When disassembly is required, the sealing plug is removed to deflate the airbag. The first spring 109 retracts and resets, causing the limiting rod 107 to disengage from the limiting hole 402, thereby releasing the restriction on the insertion rod 401 and allowing the connecting arm 1 to be removed.

[0035] See Figure 8-9The rearview mirror cover 2 consists of a lower cover 202, an upper cover 203 and a base 201. The upper cover 203 is snapped onto the lower cover 202, and the base 201 is fixed onto the lower cover 202. An interior rearview mirror is mounted on the base 201, and multiple buffer pads 204 are also provided on the lower cover 202.

[0036] See Figure 8-9 A ball joint is provided between the lower cover 202 and the upper cover 203. The ball head 3 is snapped into the ball joint. A USB structure is also provided on one side of the lower cover 202.

[0037] See Figure 1 The rearview mirror cover 2 has a third airbag 5 at the top and bottom of its side wall. The third airbag 5 is a strip structure. When the driver adjusts the angle of the rearview mirror, he directly moves the rearview mirror cover 2 by hand. The two third airbags 5 can improve the comfort of adjustment.

[0038] See Figure 6-7 A locking block 404 is symmetrically fixed on the mounting base 4. The locking block 404 has a locking groove 405. A fixing rod 7 is fixed to both sides of the connecting arm 1. A sleeve 8 is fixed to one end of each fixing rod 7. Air pipes 6 are connected to both third airbags 5. One end of each air pipe 6 is connected to one sleeve 8. A second spring 11 is connected to the inner wall of the sleeve 8. One end of the second spring 11 is connected to a second piston block 9. A locking rod 10 is fixed to the side wall of the second piston block 9. One end of the locking rod 10 penetrates the side wall of the sleeve 8, and the locking rod 10 matches the size of the locking groove 405. (The last sentence appears to be incomplete and possibly refers to adjusting the rearview mirror.) When adjusting the position, the driver holds the rearview mirror with one hand and pulls it forcefully. While holding the rearview mirror cover 2, the gas in the third airbag 5 is sent into the sleeve 8 through the vent pipe 6, pushing the second piston block 9 and the locking rod 10 to move. The second spring 11 is stretched, and the locking rod 10 is locked into the slot 405 of the locking block 404, fixing the position of the connecting arm 1. During adjustment, the connecting arm 1 cannot move slightly, thus ensuring stability during adjustment. After adjustment, the hand is released, the second spring 11 returns to its original position, driving the second piston block 9 and the locking rod 10 to return to their original positions. Even when not adjusting, the buffering effect can still be guaranteed.

[0039] The working principle of this invention is as follows: First, the mounting base 4 is fixed to the windshield of the car. The connecting arm 1 is brought close to the mounting base 4, and the two insert rods 401 are inserted into the second fixing groove 108. The extrusion block 403 enters the first fixing groove 101. When the extrusion block 403 enters the first fixing groove 101, it will extrude the first airbag 102. The gas in the first airbag 102 is discharged through the first connecting pipe 105. Then, it pushes the first piston block 106 and the limiting rod 107 to move, and stretches the first spring 109. The limiting rod 107 gradually approaches the insert rod 401 and abuts against the insert rod 401. When the limiting rod 107 is not inserted into the limiting hole 402, some of the gas in the first airbag 102 enters the second airbag 111 through the second connecting pipe 110, causing the second airbag 111 to inflate until the connecting arm 1 contacts the mounting base 4. 07 will be inserted into the limiting hole 402. This means that part of the gas in the first airbag 102 is used to push the first piston block 106 to move, and the other part of the gas enters the second airbag 111. The second airbag 111 covers the outside of the insert rod 401. After the connecting arm 1 is fixed, the rearview mirror cover 2 can be installed on the ball head 3. The lens can be assembled on the base 201. The lower cover 202 and the upper cover 203 are separated into two parts and assembled together by a snap-fit ​​structure. If replacement is needed, only the upper cover 203 needs to be removed and replaced. If the connecting arm 1 needs to be removed, only the sealing plug needs to be removed, and the gas in the first airbag 102 is released through the inflation / deflation pipe 112. The first spring 109 retracts and resets, driving the limiting rod 107 to disengage from the limiting hole 402, thereby releasing the restriction on the insert rod 401 and removing the connecting arm 1.

[0040] The main function of the insert rod 401 is to prevent the connecting arm 1 from detaching from the mounting base 4. The width of the second fixing groove 108 should be greater than the width of the insert rod 401 so that the connecting arm 1 has a certain amount of room to move. The second airbag 111 can prevent the connecting arm 1 from shaking randomly. When the car experiences severe vibration, the connecting arm 1 will move slightly and squeeze the second airbag 111 to buffer the impact. The non-rigid connection method can avoid damage to electronic components caused by severe vibration.

[0041] Since the connecting arm 1 is movable, when adjusting the rearview mirror angle, the driver's arm grips the rearview mirror cover 2, which will cause the connecting arm 1 to move together. Therefore, the third airbag 5 is provided to increase comfort. On the other hand, when the rearview mirror cover 2 is gripped, the gas in the third airbag 5 is sent into the sleeve 8 through the vent pipe 6, which pushes the second piston block 9 and the locking rod 10 to move. The second spring 11 is stretched, and the locking rod 10 is locked into the slot 405 of the locking block 404, so that the position of the connecting arm 1 is fixed. During adjustment, the connecting arm 1 cannot move slightly, thus ensuring the stability during adjustment. After the adjustment is completed, the hand is released, the second spring 11 returns to its original position, and the second piston block 9 and the locking rod 10 return to their original position. The cushioning effect can still be guaranteed when not adjusting.

[0042] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
