Description

Technical Field

[0001] This utility model relates to the field of tilting empty vehicle lights, and more particularly to a tilting empty vehicle light that can adapt to high torque. Background Technology

[0002] With the development of urbanization and motorization in my country, the urban population and area are constantly increasing, and people's demand for public transportation is rising sharply. Taxis have become a major mode of transportation. According to surveys, there are an average of eight taxis per 10,000 people in my country. Taxis are cars hired temporarily, and fares are usually charged by mileage or time. To allow passengers to see if the car is occupied while driving, taxis typically have a "vacant" light. However, existing "vacant" lights are prone to motor damage due to excessive torque, affecting their operation. Furthermore, the lights are too high, which can obstruct the driver's view while driving. Also, the lights can only be manually flipped up and down by the driver and cannot be automatically adjusted based on available orders, making operation inconvenient.

[0003] Chinese Patent Publication No. CN214822902U discloses an automatic taxi vacant light flipper, comprising a base, a housing fixedly mounted on the top of the base, a circuit board fixedly mounted inside the housing, a control key electrically connected to the circuit board embedded on the outside of the housing, a control switch electrically connected to the circuit board embedded on the left side of the housing, two connecting seats fixedly mounted on the top of the housing, a limit plate fixedly mounted on the right side of the housing, an LED screen embedded on the right side of the housing, a rotating shaft movably mounted on opposite sides of the two connecting seats, a rotating gear fixedly mounted outside the rotating shaft located inside the front connecting seat, and a drive motor fixedly mounted on the top of the base located inside the housing. This automatic taxi vacant light flipper is more convenient and simple to use, requiring no action from the driver, and automatically flips the vacant light after a passenger boards, reducing safety hazards. This patent uses a gear transmission method, where the torque of the motor is fully transmitted with each rotation. When manually flipped, the rotation is also transmitted to the motor, which can easily damage the motor and affect subsequent use. In addition, the empty vehicle light is placed above the base, and its height is relatively large when closed, which can easily obstruct the driver's view.

[0004] Chinese Patent Publication No. CN214822903U discloses an electric taxi vacant light, including a motor connected to the rotating shaft of the vacant light, and the motor is communicatively connected to a controller. The advantages of this invention are: by adding a motor to the existing vacant light and connecting it to the rotating shaft, the motor can control the vacant light to rotate and change its state. Simultaneously, the controller communicates with the motor via wired or wireless means, allowing the controller to control the motor's rotation. This eliminates the need for manual rotation to control the vacant light's state. The controller can be placed in a suitable location inside the vehicle as needed, reducing driver fatigue by eliminating the need to bend over. Furthermore, the modification is extremely convenient, requiring no changes to the original structure of the vacant light, resulting in low cost and easy promotion. However, while this patent achieves automatic rotation of the vacant light, its motor still suffers from excessive torque, which can easily lead to damage, and the vacant light's height is too high, obstructing the driver's view and affecting driving safety. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing vehicle vacancy lights often suffer from excessive torque, leading to motor damage and affecting usability. Furthermore, their considerable height can obstruct the driver's view while driving. Additionally, the lights can only be manually flipped and raised by the driver, and cannot be automatically flipped according to orders on the vehicle, making operation inconvenient. To address these shortcomings of the prior art, this invention provides a flip-up vehicle vacancy light that can adapt to high torque.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A high-torque-adaptable tilting empty vehicle light is constructed, comprising a base and a rotating mechanism disposed within the base. The empty vehicle light is connected to the side of the base and is connected to the rotating mechanism via a connecting arm. The rotating mechanism includes a motor and a rotating shaft connected to the motor. The rotating shaft rotates under the drive of the motor to drive the connecting arm to rotate, thereby tilting the empty vehicle light. The rotating mechanism also includes a gear set. The motor and the rotating shaft are connected via the gear set. The motor drives the gear set to rotate, which in turn drives the rotating shaft to rotate, thereby tilting the empty vehicle light. Alternatively, the tilting of the empty vehicle light causes the rotating shaft to rotate, and the rotation is isolated and transmitted to the motor under the action of the gear set.

[0008] Preferably, the gear set includes a first gear and a second gear disposed opposite to the first gear. The first gear has a toothed insertion hole on one side, which corresponds to the motor shaft and rotates with the motor shaft, causing the first gear to rotate with the motor shaft. The second gear has a toothed post on one side, and the shaft has a shaft insertion hole corresponding to the toothed post. The toothed post and the shaft insertion hole correspond to each other, causing the shaft to rotate synchronously with the second gear. Both the first gear and the second gear have toothed sets on their opposing surfaces, which counteract the torque of the motor.

[0009] Preferably, the base is provided with a fixing plate, the fixing plate is provided with a toothed connecting hole, the gear set is placed in the toothed connecting hole, and the toothed connecting hole limits the gear set in the upward direction.

[0010] Preferably, the rotating mechanism further includes a rotating shaft bracket, the rotating shaft bracket is provided with a fixing hole, the rotating shaft includes a rotating shaft insert that passes through the fixing block, and a stroke mechanism is provided between the rotating shaft bracket and the rotating shaft to limit the flip angle of the empty vehicle light.

[0011] Preferably, the travel mechanism includes a travel groove disposed in a fixed hole and a travel block disposed on a rotating shaft. The travel block has a flip travel of the empty vehicle light at both ends of the travel groove. A protrusion is disposed on the rotating shaft insert. The connecting arm corresponds to the rotating shaft insert and is connected to the rotating shaft insert through the protrusion to make the rotating shaft and the connecting arm rotate synchronously.

[0012] Preferably, a stop plate is provided on the rotating shaft, the radius of the stop plate is larger than the radius of the fixing hole, the stop plate is in contact with the rotating shaft bracket, and the stroke block is set close to the stop plate.

[0013] Preferably, a rotating plate is provided on the rotating shaft, and micro switches are provided on both sides of the rotating shaft corresponding to the rotating plate. When the rotating shaft rotates to both ends of the stroke mechanism, the rotating plate exerts a pressing force on one of the micro switches.

[0014] Preferably, a pressing column is provided on the rotating shaft bracket, the pressing column is positioned above the rotation range of the rotating plate, and a pressing column fixing plate is provided on the base. The pressing column and the pressing column fixing plate are connected to limit the rotation mechanism.

[0015] Preferably, the base includes a front shell and a bottom shell disposed below the front shell. A control board fixing post is disposed inside the bottom shell, and a control board is connected to the control board fixing post. A support plate is disposed on the side of the bottom shell corresponding to the connecting arm, and the support plate supports the connecting arm. The empty vehicle light includes a lamp housing and a lamp panel connected to the lamp housing. A lamp plate is disposed between the lamp housing and the lamp panel.

[0016] Preferably, the control board includes an interface circuit, a motor drive circuit and a vehicle vacancy light switch circuit electrically connected to the interface circuit. The motor drive circuit is connected to a first micro switch and a second micro switch. The second micro switch is connected to the vehicle vacancy light switch circuit. When the interface circuit receives an order end signal, the motor drive circuit will drive the second micro switch to turn on the vehicle vacancy light. When the interface circuit receives an order start signal, the motor drive circuit will drive the first micro switch to retract the vehicle vacancy light.

[0017] The beneficial effects of this utility model are as follows: By setting a gear set on the rotating mechanism, the sliding of the teeth between the gears reduces the excessive rotational torque of the motor, which can damage the motor. Simultaneously, the torque when manually flipping the empty vehicle light cannot be transmitted to the motor, extending its service life. Furthermore, the rotational sound between the teeth is crisper, and the flipping feel is better. A stroke mechanism corresponding to a micro switch is set on the rotating shaft bracket, allowing the micro switch to be pressed when the stroke mechanism reaches its limit, thus retracting and raising the empty vehicle light, making it more convenient. Simultaneously, when raised, the empty vehicle light illuminates, making the empty vehicle indicator more clearly visible. The rotating shaft bracket and fixing plate limit the rotating mechanism, preventing movement that could affect the transmission. The L-shaped connecting arm positions the empty vehicle light on the side of the base, reducing its impact in the height direction when retracted. The high height of the empty vehicle light can obstruct the driver's view, improving driving safety. Additionally, because the interface connects to the order status, automatic control of the motor rotation can be achieved to activate the micro switch and flip the empty vehicle light, making operation more convenient and intelligent.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] A preferred embodiment of this utility model provides a tilting empty vehicle light that can adapt to high torque; such as... Figure 1-2As shown, the device includes a base 20 and an vacant vehicle light 10 connected to the base. A control board 30 and a rotating mechanism 50 connected to the control board are installed inside the base. The control board controls the rotating mechanism to flip and fold the vacant vehicle light. The control board has an interface 300 that reads order information. When an order is received and a passenger boards, the interface data is sent to the control board, which then drives the rotating mechanism to fold the vacant vehicle light 10. When the interface reads the order information, the control board controls the rotating mechanism to fold the vacant vehicle light back up, achieving more intelligent control over the raising and lowering of the vacant vehicle light.

[0034] Specifically, such as Figure 1-3 and Figure 7-8 As shown, the base 20 includes a front shell 200 and a bottom shell 201 located below the front shell. A step 2000 is provided at the opening of the front shell, and the bottom shell 201 is positioned at the step, with its thickness matching the step height. A locking pin 2002 is provided inside the front shell. Screws pass through the bottom shell and connect to the locking pin to lock the front shell and bottom shell together, ensuring the bottom shell end face is flush with the outer edge of the front shell after locking. To enhance the strength of the front shell, reinforcing plates 2001 are provided on the inner walls of the front shell sides, and reinforcing plates are also connected around the locking pins. A control plate 30 and a rotating mechanism 50 are connected to the bottom shell. A control plate fixing pin 2010 is provided on the bottom shell corresponding to the control plate 30, allowing the control plate to be fixed to the bottom shell. An arc-shaped opening 2003 is provided on the side of the front shell 20, through which a connecting arm passes and connects to the rotating mechanism 50, allowing it to rotate under the action of the rotating mechanism.

[0035] Furthermore, such as Figure 4-6 As shown, the rotating mechanism 50 includes a motor 500 and a gear set 505 that rotates coaxially with the motor. When the motor is working, it drives the gear set to rotate. The gear set is connected to a rotating shaft 503, which rotates under the rotation of the gear set. The rotating shaft is connected to the connecting arm, thereby driving the connecting arm to rotate and causing the empty vehicle light to flip. The rotating shaft 503 is mounted on the base shell through a rotating shaft bracket 504, which restricts the rotating shaft and prevents it from shifting.

[0036] Furthermore, such as Figure 4-6As shown, the gear set 505 includes a first gear 5050 with a toothed insertion hole 5052 facing the motor. The motor shaft 5000 is inserted into the toothed insertion hole and drives the first gear to rotate with the motor shaft. Therefore, the motor shaft cannot be cylindrical. The gear set 505 also includes a second gear 5051 with a toothed insertion post 5054 facing away from the first gear. The shaft has a shaft insertion hole 5034 corresponding to the toothed insertion post. The rotation of the second gear drives the shaft to rotate, or the rotation of the shaft drives the second gear to rotate. Both the first and second gears have teeth 5053 on their opposing surfaces. These teeth prevent excessive motor torque from damaging the motor. When the motor shaft drives the first gear to rotate, the presence of the gears will offset part of the rotational force of the first gear on the second gear, reducing the torque. At the same time, when the vehicle light is manually flipped in the opposite direction, the large torque can also be offset by the gear set, preventing the large torque from being transmitted to the motor and causing motor damage.

[0037] Furthermore, such as Figure 4-6 As shown, a first micro switch 501 and a second micro switch 502 are respectively provided on the left and right sides of the rotating shaft 503. A rotating plate 5030 is provided on the rotating shaft corresponding to the two sets of micro switches. The rotating plate rotates with the rotating shaft 503. When the rotating plate rotates to the position of the first micro switch, the empty vehicle light is in the upright state. The corresponding light can be controlled to light up by the first micro switch to make the empty vehicle light more obvious after it is upright. At the same time, when the rotating plate reaches the second micro switch, the empty vehicle light is in the retracted state. The corresponding light can be controlled to turn off by the second micro switch. Or when the second micro switch is in the unloaded state, that is, when the first micro switch is open, the corresponding empty vehicle light is turned off. In this way, the rotating plate 5030 presses the first micro switch 501 and the second micro switch 502 to control the lighting and turning off of the empty vehicle light.

[0038] Furthermore, such as Figure 3-8As shown, to avoid excessive friction during rotation due to an excessively large contact area between the shaft and the external contact, the shaft 503 is supported by a shaft bracket 504. An insertion part 5043 is provided at the lower end of the shaft bracket, and a support groove 2012 is provided on the bottom 201 corresponding to the insertion part. Placing the insertion part in the support groove increases the height of the shaft bracket and prevents it from moving forward and backward. A fixing foot 5041 is provided on the side of the shaft bracket away from the motor. The fixing foot is fixed by locking the locking pin on the bottom housing. Because the insertion makes the fixing foot relatively suspended, a bracket reinforcing plate 5044 is also connected to the fixing foot to increase its strength. A fixing hole 5045 is provided in the middle of the shaft bracket. The shaft is inserted into the fixing hole, and the shaft insertion pin 5035 passes through the fixing hole and connects to the connecting arm 102. The pivot pin is provided with a protrusion 5033, and the connecting arm is provided with a connecting arm insertion hole 105 corresponding to the pivot pin. The shape of the connecting arm insertion hole corresponds to that of the pivot pin, so that the pivot pin and the connecting arm rotate synchronously. The bottom shell 201 is provided with a support plate 2011 corresponding to the arc-shaped opening 2003. The connecting arm is placed in the arc-shaped opening and supported by the support plate. Since the connecting arm is L-shaped, the empty vehicle light can be flipped on the side of the base, making the flipping more convenient. The length of the connecting arm can also be set according to the requirements.

[0039] Furthermore, such as Figure 4-8 As shown, a stop plate 5031 is provided in the middle of the rotating shaft 503. The area of ​​the stop plate is larger than the area of ​​the fixing hole 5045, thereby preventing the rotating shaft from passing through the fixing hole. Two sets of pressing columns 5040 are also provided on the rotating shaft bracket. The pressing columns are positioned in the front of the rotating plate's range of motion to prevent the rotating shaft from moving up and down. A pressing column fixing plate 2104 is provided on the bottom shell. The pressing columns and the pressing column fixing plate are locked together with screws to fix the rotating shaft bracket. At the same time, the rotating shaft bracket and the pressing column fixing plate fix the rotating shaft in place, so that the rotating shaft cannot be moved and can only rotate. A gear connecting hole 2013 is provided in the middle of the pressing column fixing plate 2014. The gear set is placed in the gear connecting hole to prevent the gear from being misaligned in the vertical direction, which would affect normal rotation. In order to limit the rotation of the empty vehicle light, a travel groove 5042 is provided in the fixing hole, and a travel block 5032 is provided on the rotating shaft corresponding to the travel groove. The travel block is located close to the stop plate so that it is tightly attached to the travel groove. When the rotating shaft rotates and the travel block is at both ends of the travel groove, the rotating plate presses the first micro switch 501 and the second micro switch 502 respectively to prevent the rotating shaft from rotating excessively.

[0040] Furthermore, such as Figure 1 and Figure 9-13As shown, the control board 30 includes an interface circuit with an interface 300. The interface circuit is connected to a motor drive power supply circuit and a motor drive circuit. The motor drive circuit is connected to the motor interface circuit and a first micro switch. When a passenger boards the vehicle, the interface circuit receives the passenger boarding information and activates the motor drive circuit. When the first micro switch is closed, the vacant vehicle light is retracted. Simultaneously, the interface circuit is connected to the vacant vehicle light power supply circuit, the vacant vehicle light interface circuit, and the vacant vehicle light switch circuit. The vacant vehicle light switch circuit is connected to the motor drive circuit and a second micro switch. When a passenger disembarks and completes their order, the interface circuit receives the passenger disembarkation and order completion information. The motor drive circuit then activates the motor drive circuit, causing the shaft to rotate to the second micro switch, closing the second micro switch and illuminating the vacant vehicle light. At this time, the vacant vehicle light stands up and illuminates.

[0041] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
