Technical Field

[0001] This disclosure relates to the field of automotive technology, and in particular to an anti-theft device for vehicle exterior rearview mirror lenses, a rearview mirror, and an anti-theft method. Background Technology

[0002] Car rearview mirrors are located on the left and right sides of the front of the car, as well as in the front of the interior. They reflect the situation behind, to the sides, and below the car, allowing the driver to see these areas clearly, acting as a "second eye" and expanding the driver's field of vision. A typical car rearview mirror generally includes a mirror housing, a mirror ring, a mirror lens, a mirror tray, and a steering mechanism mounted on the mirror tray. This steering mechanism is used to adjust the viewing angle of the mirror to obtain a suitable range of vision for observing the situation on both sides and behind the vehicle.

[0003] In related technologies, in order to ensure the safety of vehicle exterior rearview mirrors, most existing rearview mirrors are designed to be opened from the inside to replace the lens. For example, the lens of the rearview mirror is connected to the back plate clip, and a lens mechanism is set inside the rearview mirror. The back plate clip and the lens mechanism are fastened together to install the lens in the rearview mirror. The lens can be removed by opening the back plate clip and the lens mechanism from the inside of the rearview mirror.

[0032] With the rapid development of the automotive industry, rearview mirrors, as an important visual aid for drivers, are crucial to driving safety in terms of safety and stability. However, in recent years, the theft of rearview mirror lenses has become increasingly common, causing significant economic losses and safety hazards to car owners. This is especially true for luxury models, where the cost of replacing rearview mirror lenses is exorbitant, further fueling owners' concerns about security. Therefore, developing an efficient and convenient anti-theft device for rearview mirror lenses is of great significance for improving vehicle safety and protecting the interests of car owners.

[0033] In related technologies, in order to ensure the safety of vehicle exterior rearview mirrors, most existing rearview mirrors are designed to be opened from the inside to replace the lens. For example, the lens of the rearview mirror is connected to the back plate clip, and a lens mechanism is set inside the rearview mirror. The back plate clip and the lens mechanism are fastened together to install the lens in the rearview mirror. The lens can be removed by opening the back plate clip and the lens mechanism from the inside of the rearview mirror.

[0034] The rearview mirrors in the relevant technologies are not equipped with anti-theft alarm modules. When someone pries or forcibly removes the mirror, the mirror cannot provide an alarm in time, thus compromising its safety.

[0035] In view of the above-mentioned technical problems, this disclosure provides an anti-theft device for vehicle exterior rearview mirror lenses, such as... Figures 1-3 As shown, the anti-theft device includes a bracket latch 7, a commutator latch 8, a pressure sensor 4, a control module, and an alarm module;

[0036] The bracket locking tongue 7 is connected to the lens bracket 3; the commutator locking tongue 8 is connected to the commutator 5; the bracket locking tongue 7 and the commutator locking tongue 8 are engaged and connected.

[0037] Pressure sensor 4 is used to obtain the pressure at the engagement point of bracket latch 7 and commutator latch 8;

[0038] The control module is used to trigger an alarm when the pressure at the engagement point of the bracket locking tongue 7 and the commutator locking tongue 8 exceeds a set pressure value.

[0039] In some instances, lens 1 is connected to lens holder 3, lens 1 is connected to lens housing, and lens holder 3 and commutator 5 are located inside lens housing.

[0040] The mirror housing includes a housing 6 and a decorative cover 2. The decorative cover 2 is provided at the outer edge of the housing 6. The lens 1 is installed in the decorative cover 2. The lens holder 3 and the commutator 5 are both located inside the housing 6.

[0041] Lens 1 is connected to lens holder 3 by adhesive bonding.

[0042] In some instances, the latching connection between the bracket latch 7 and the commutator latch 8 is as follows: Figure 2 , Figure 3 As shown, the bracket locking tongue 7 includes a first support, the first end of which is connected to the lens holder 3, and the second end of which extends inward to form a first protrusion; the commutator locking tongue 8 includes a second support, the first end of which is connected to the commutator 5, and the second end of which extends outward to form a second protrusion; after the bracket locking tongue 7 and the commutator locking tongue 8 are fastened together, the first support is sleeved on the outside of the second support, the second protrusion extends between the first protrusion and the lens holder 3, and the first protrusion extends between the second protrusion and the commutator 5.

[0043] The first support and the second support are both circular ring supports; the second end of the first support extends inward, meaning that the second end of the first support extends towards the center of the circle at the second end; the second end of the second support extends outward, meaning that the second end of the second support extends away from the center of the circle at the second end.

[0044] To facilitate the engagement of the bracket latch 7 and the reversing latch 8, such as Figure 3 As shown, a first inclined edge is provided on the inner ring of the end face of the first boss facing the commutator 5; the angle between the first inclined edge and the end face of the first boss facing the commutator 5 is an obtuse angle.

[0045] In one possible implementation, a second inclined edge is provided on the outer ring of one end face of the second boss facing the lens holder 3; the angle between the second inclined edge and the end face of the second boss facing the lens holder 3 is an obtuse angle.

[0046] The cooperation of the first and second inclined sides facilitates the locking of the bracket latch 7 and the reversing latch 8 together.

[0047] When the lens is damaged and needs to be replaced, the housing is disassembled, and the bracket locking tongue 7 is pried open with a tool to separate the latched bracket locking tongue 7 and the commutator locking tongue 8. In order to facilitate prying open the bracket locking tongue 7, multiple first protrusions can be set. Multiple first protrusions are evenly distributed around the second end of the first support, and a groove of a set depth is set on the second end of the first support. The groove extends from the second end of the first support to the first end of the first support to a set depth. Using this groove, it is easy to insert a tool to pry open the bracket locking tongue 7.

[0048] When personnel tamper with or forcibly remove the lens, damaging the lens, the bracket locking tongue 7 and the commutator locking tongue 8 will press against the pressure sensor, increasing the pressure at the engagement point of the bracket locking tongue 7 and the commutator locking tongue 8. In order to ensure that the pressure sensor 4 accurately obtains the pressure at the engagement point of the bracket locking tongue 7 and the commutator locking tongue 8, the pressure sensor 4 is set at the point where the first boss and the second boss meet.

[0049] Preferably, the pressure sensor 4 is disposed on the end face of the second protrusion facing the first protrusion, so that the pressure sensor 4 does not need to be replaced when the lens 1 is replaced, thus reducing costs.

[0050] The pressure sensor 4 is ring-shaped and connected to the second boss near the inner ring. The ring-shaped pressure sensor 4 is coaxial with the second boss so as to accurately obtain the pressure at the engagement point of the bracket latch 7 and the reversing latch 8.

[0051] This disclosure provides an anti-theft device for vehicle exterior rearview mirror lenses, which also includes a control module and an alarm module. Both the pressure sensor and the alarm module are communicatively connected to the control module. The control module receives the pressure signal acquired by the pressure sensor and controls the alarm module according to the received pressure signal.

[0052] like Figure 4 As shown, pressure sensor 4 is used to obtain the pressure at the engagement point of bracket latch 7 and commutator latch 8.

[0053] The control module is used to control the alarm module to sound an alarm when the pressure at the engagement point of the bracket latch 7 and the commutator latch 8, as detected by the pressure sensor 4, exceeds the set pressure value. This alerts the vehicle owner and surrounding personnel, promptly preventing further damage to the rearview mirror and improving its safety.

[0054] The alarm module uses an audible and visual alarm module, such as a flashlight and a buzzer, which emits audible and visual alarm signals to trigger an alarm.

[0055] This disclosure provides an anti-theft device for a vehicle exterior rearview mirror lens. The lens bracket is connected to a bracket latch, and the commutator is connected to a commutator latch. The bracket latch and the commutator latch are engaged, making it difficult to remove the rearview mirror lens from the outside, thus providing a certain degree of anti-theft effect. A pressure sensor acquires the pressure at the engagement point of the bracket latch and the commutator latch. When the pressure at the engagement point exceeds a set pressure value, the alarm module is activated. This allows for monitoring of actions that damage the lens, such as prying or forcibly removing the lens, and provides timely alarms, improving the safety performance of the rearview mirror.

[0056] This disclosure also provides a vehicle exterior rearview mirror, including the aforementioned vehicle exterior rearview mirror lens anti-theft device.

[0057] This disclosure also provides an anti-theft method for the aforementioned vehicle exterior rearview mirror lens anti-theft device, including:

[0058] Obtain the pressure at the engagement point of the bracket latch and the commutator latch;

[0059] When the pressure at the engagement point of the bracket latch and the commutator latch exceeds the set pressure value, the control alarm module will sound an alarm.
