Description

Technical Field

[0001] The utility model relates to the field of electric lifting cup holders, in particular to an electric lifting cup holder based on a LIN bus protocol. Background Art

[0002] The LIN (Local Interconnect Network) bus is a low-cost serial communication network designed for distributed automotive electronic systems. It complements other multi-channel automotive networks, such as the Controller Area Network (CAN), and is suitable for applications that don't place high demands on network bandwidth, performance, or fault tolerance. The LIN bus is based on the SCI (UART) data format and employs a single-master / multiple-slave model, making it a special case of the UART.

[0003] With the increasing intelligence of cars and the advancement of interior design, car owners are increasingly demanding comfort and convenience inside their vehicles. Traditional cup holders are typically fixed and cannot be adjusted at different heights to accommodate beverage containers of varying sizes. Consequently, electric cup holders are now available on the market. When a beverage container is needed, the lifting mechanism lowers to create a storage space; when not in use, the mechanism raises to maintain a smooth, aesthetically pleasing surface without interfering with other items.

[0004] However, current electric lift cup holders usually have their own switches for lifting, but a car is usually equipped with multiple electric lift cup holders, which makes the wiring complicated. Moreover, with the current development of intelligent cars, they are relatively independent and not integrated with the car terminal control system, which is inconvenient for users to use and operate. Failure of the electric lift cup holder is also not easy for users to detect, resulting in motor overheating and damage. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model provides an electric lifting cup holder based on the LIN bus protocol, which realizes communication with the vehicle terminal system based on the LIN bus protocol, which not only simplifies the overall wiring, but also facilitates the user's actual operation, use, and fault discovery, greatly improving the user experience.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A LIN bus protocol-based electrically liftable cup holder comprises a cup holder body and a lifting structure capable of performing lifting motion within the cup holder body. The LIN bus protocol-based electrically liftable cup holder further comprises a control module and a drive module for driving the lifting structure to move upward and downward. The control module is communicatively connected to an on-board terminal system based on the LIN bus protocol, and is communicatively connected to the drive module based on the LIN bus protocol. The control module is configured to receive a cup holder lifting signal transmitted by the on-board terminal system and transmit a LIN communication signal to the drive module to control the operating state of the drive module.

[0008] The above structure allows the user to directly control the lifting structure of the electric lifting cup holder through the vehicle terminal system. Specifically, if the user wants to raise the lifting structure, the user can perform relevant operations on the vehicle terminal system. At this time, the vehicle terminal system sends an ascending instruction to the control module based on the LIN bus protocol, and the control module sends an ascending instruction to the drive module based on the LIN bus protocol. After receiving the ascending instruction, the drive module works to drive the lifting structure to rise. If the user wants to lower the lifting structure, the user can perform relevant operations on the vehicle terminal system. At this time, the vehicle terminal system sends a descending instruction to the control module based on the LIN bus protocol, and the control module sends a descending instruction to the drive module based on the LIN bus protocol. After receiving the descending instruction, the drive module works to drive the lifting structure to descend. The vehicle terminal system includes one or more of a car central control button, a car central control screen, and a car central control remote control. If the car terminal system also supports a mobile phone APP, the user can also control the electric lifting cup holder through the mobile phone APP. The user can also very conveniently control and adjust the raising or lowering distance of the lifting structure to accommodate different types of cups.

[0009] The above structure enables users to more conveniently control the electric lifting cup holder. If the car terminal system is a car central control screen, the graphical interface can make the control more intuitive, such as which position of the cup holder to operate. And because it is based on the LIN bus protocol, the overall wiring can be simplified.

[0010] Furthermore, the driving module feeds back its current state to the control module based on the LIN bus protocol, and the control module feeds back the received feedback information of the driving module to the vehicle terminal system based on the LIN bus protocol.

[0011] The above method makes the electric lifting cup holder more reasonable; specifically, the vehicle terminal system can obtain the current status of the lifting structure according to the feedback signal; if the car wash terminal system is a central control screen, the user can clearly and intuitively understand the current status of each electric lifting cup holder on the car, so as to facilitate the relevant adjustment; at the same time, when the lifting structure fails to lift, that is, the driving module fails to work, based on the LIN bus protocol, the fault signal can be fed back to the vehicle terminal system, so that the user can understand the fault in time, and some fault codes are displayed to the user for the user to perform simple troubleshooting.

[0012] Furthermore, the control module is communicatively connected to the vehicle terminal system via an in-vehicle LIN communication bus circuit, and the control module is a slave node of the in-vehicle LIN communication bus circuit;

[0013] The control module includes a control module body for data processing and a LIN transceiver for transmitting and receiving LIN signals. The control module body is connected to the LIN transceiver, and the LIN transceiver is connected to the drive module based on the LIN bus protocol.

[0014] The above structure makes the electric lifting cup holder more reasonable.

[0015] Furthermore, the control module includes an LDO unit for converting an external input voltage into a voltage required by the microprocessor.

[0016] The above structure makes the control module more reasonable; the output end of the LDO unit is externally connected to a filter capacitor and then supplies power to the control module, making the power supply of the control module more stable; specifically, the output end of the LDO unit is externally connected to 0.1μF and 10μF filter capacitors and then supplies power to the control module.

[0017] Furthermore, the driving module has a first LIN communication port, a first Vbat port and a first GND port, the control module has a second LIN communication port, a second Vbat port and a second GND port, the first LIN communication port and the second LIN communication port are communicatively connected, the first Vbat port and the second Vbat port are both connected to the power supply, and the first GND port and the second GND port are both grounded.

[0018] The above structure makes the driving module and the control module more reasonable.

[0019] Furthermore, the LIN communication protocol between the control module and the drive module includes a LIN control frame and a LIN status frame;

[0020] The driving module is capable of receiving a LIN control frame sent to it by the control module, and the driving module controls its working state according to the LIN control frame;

[0021] The driving module can feed back a corresponding LIN status frame to the control module according to its own current status.

[0022] By adopting the above-mentioned method, the communication between the control module and the drive module is made more reasonable, stable and reliable.

[0023] Furthermore, the LIN communication protocol between the control module and the drive module also includes a LIN diagnostic frame.

[0024] In the above manner, the LIN diagnostic frame is used by the drive module to feedback fault and abnormality information to the control module, so that the control module can feedback information to the vehicle terminal system, so that the vehicle terminal system can feedback and display it to the user.

[0025] Furthermore, the LIN communication protocol between the control module and the drive module can be customized. For example, the manufacturer can use a certain frame in the communication to transmit a certain functional signal.

[0026] By adopting the above-mentioned method, more information can be transmitted between the control module and the drive module, so that the manufacturer can add more functions during factory settings, thereby making the electric lifting cup holder more applicable.

[0027] Furthermore, the electric lifting cup holder based on the LIN bus protocol includes a cup holder lifting switch; the control module is connected to the cup holder lifting switch to receive a switch signal sent by the cup holder lifting switch and send a corresponding LIN communication signal to the driving module to control the working state of the driving module.

[0028] With the above-mentioned method, the user can operate the cup holder lifting switch to raise or lower the lifting structure. The user can select the desired method to control the electric lifting cup holder, which is convenient for the user's actual use. Of course, when the lifting structure is controlled by operating the cup holder lifting switch, the driving module will also provide feedback to the control module, and the control module will provide feedback to the vehicle terminal system to achieve synchronization.

[0029] Typically, the cup holder lifting switch is disposed on the corresponding cup holder body or at a peripheral position thereof for easy operation by the user;

[0030] Specifically, one pin of the cup holder lifting switch is grounded, and the other pin is connected to the control module; when the user presses the cup holder lifting switch and lifts it, the control module receives a low-level signal, and the control module sends a corresponding instruction to the drive module according to the signal. For example, when the lifting structure is currently in a high position, the operator presses the cup holder lifting switch, and the control module sends a descending instruction to the drive module; when the lifting structure is currently in a low position, the operator presses the cup holder lifting switch, and the control module sends an ascending instruction to the drive module; the cup holder lifting switch can be a mechanical switch, a capacitive switch, or any other type of switch.

[0031] Furthermore, the driving module includes a driving motor and a motor driving unit for controlling and driving the driving motor; the motor driving unit and the control module are communicatively connected based on a LIN bus protocol.

[0032] The above structure makes the driving module more reasonable.

[0033] Furthermore, the driving motor is a stepping motor.

[0034] The above structure makes it easy to control the lifting position of the lifting mechanism, that is, to control the rising or falling distance of the lifting mechanism.

[0035] Furthermore, the electric lifting cup holder based on the LIN bus protocol has a self-learning capability to determine the total up and down movement stroke of the lifting structure;

[0036] The self-learning includes: the driving module continuously works to drive the lifting structure to move up or down until the lifting structure cannot move in this direction to confirm the first endpoint; the driving module drives the lifting structure to move in the opposite direction until the lifting structure cannot move in this direction to confirm the second endpoint, and the distance between the first endpoint and the second endpoint is the total up and down movement stroke of the lifting structure.

[0037] By adopting the above method, the total up and down movement stroke of the lifting structure is obtained through self-learning, and the driving module subsequently drives the lifting structure only within the total up and down movement stroke range, that is, between the first end point and the second end point, thereby avoiding the blocking of the driving module during subsequent operation and effectively extending the service life of the driving module.

[0038] Furthermore, the control module communicates with the vehicle-mounted terminal system based on the LIN bus protocol and feeds back the total up and down movement stroke of the lifting structure to the vehicle-mounted terminal system.

[0039] By adopting the above method, the vehicle-mounted terminal system can display the total up and down movement stroke of the lifting structure on the vehicle terminal system, so that the user can adjust the lifting position of the lifting structure. For example, the percentage adjustment is adopted, that is, the current lifting structure is controlled to move to a certain percentage of the total stroke, making the adjustment more flexible and convenient.

[0040] Furthermore, if the driving module itself does not have a self-learning capability, the control module communicates with the driving module based on the LIN bus protocol to control the operation of the driving module, and the control module confirms the first endpoint and the second endpoint based on the stall information fed back to it by the driving module based on the LIN bus protocol to obtain the total vertical movement stroke of the lifting structure; the control module feeds back the total vertical movement stroke of the lifting structure to the on-board terminal system based on the LIN bus protocol;

[0041] If the driving module itself has self-learning capability, the control module sends a self-learning instruction to the driving module based on the LIN bus protocol, and the driving module self-learns to confirm the first endpoint and the second endpoint to obtain the total up and down movement stroke of the lifting structure; and the driving module feeds back the total up and down movement stroke of the lifting structure to the control module based on the LIN bus protocol, and the control module then feeds back the total up and down movement stroke of the lifting structure to the on-board terminal system based on the LIN bus protocol.

[0042] With the above structure, the electric lifting cup holder can still achieve its self-learning capability even when using a driving module that does not have the self-learning capability, so that it can be adapted to a wider range of driving modules.

[0043] Furthermore, when the driving module is stalled or the lifting structure exceeds the lifting stroke, the self-learning of the electric lifting cup holder based on the LIN bus protocol will be triggered.

[0044] The above-mentioned method makes the triggering mechanism of the self-learning more reasonable.

[0045] Furthermore, the state of the driving module itself includes its current moving position.

[0046] By adopting the above method, the main control chip of the car can obtain the current movement position of the drive module; since the on-board terminal system has the ability to store data persistently, when the car starts, the on-board terminal system can control the drive module according to the position information and total stroke information of the drive module stored therein to avoid the drive module from over-moving, that is, stalling; the drive module body in the drive module adopts a stepper motor, so the current movement position of the drive module is the angle information currently output by the stepper motor.

[0048] (1) The electric lifting cup holder based on the LIN bus protocol of the present invention realizes communication with the vehicle terminal system based on the LIN bus protocol, which not only simplifies the overall wiring, but also facilitates the user's actual operation, use, and fault discovery, greatly improving the user's experience.

[0063] See Figures 1 to 3 The present invention provides an electric lifting cup holder based on the LIN bus protocol, comprising a cup holder body 1 and a lifting structure 2 capable of performing lifting motion in the cup holder body 1. The electric lifting cup holder based on the LIN bus protocol further comprises a control module 3 and a drive module 4 for driving the lifting structure 2 to move up and down. The control module 3 is communicably connected to an on-board terminal system 5 based on the LIN bus protocol.

The control module 3 is configured to receive a cup holder lifting signal sent by the on-board terminal system 5 and send a LIN communication signal to the drive module 4 to control the operating state of the drive module 4.

[0064] With the above structure, the user can directly control the lifting structure 2 in the electric lifting cup holder through the vehicle terminal system 5; specifically, if the user wants to make the lifting structure 2 rise, the user can perform relevant operations on the vehicle terminal system 5, at this time, the vehicle terminal system 5 sends an ascending instruction to the control module 3 based on the LIN bus protocol, and the control module 3 sends an ascending instruction to the drive module 4 based on the LIN bus protocol. After receiving the ascending instruction, the drive module 4 works to drive the lifting structure 2 to rise; if the user wants to make the lifting structure 2 fall, the user can perform relevant operations on the vehicle terminal system 5, When the vehicle terminal system 5 sends a descending instruction to the control module 3 based on the LIN bus protocol, the control module 3 sends a descending instruction to the drive module 4 based on the LIN bus protocol, and the drive module 4 works after receiving the descending instruction to drive the lifting structure 2 to descend; the vehicle terminal system 5 includes one or more of a car central control button, a car central control screen, a car central control remote control, etc.; if the car terminal system also supports a mobile phone APP, the user can also control the electric lifting cup holder through the mobile phone APP; and the user can also very conveniently control and adjust the rising or falling distance of the lifting structure 2 to adapt to different types of cups;

[0065] The above structure allows users to more conveniently control the electric lifting cup holder. If the vehicle terminal system is a central control screen, the graphical interface can make the control more intuitive, such as which cup holder position to operate. And because it is based on the LIN bus protocol, the overall wiring can be simplified.

[0066] The cup holder body 1 and the lifting structure 2 are prior art. Figure 2 shown.

[0067] Furthermore, the driving module 4 feeds back its current state to the control module 3 based on the LIN bus protocol, and the control module 3 feeds back the feedback information of the driving module 4 received to the vehicle terminal system 5 based on the LIN bus protocol.

[0068] The above-mentioned method makes the electric lifting cup holder more reasonable; specifically, the automobile terminal system can obtain the current state of the lifting structure 2 according to the feedback signal; if the car wash terminal system is a central control screen, the user can clearly and intuitively understand the current state of each electric lifting cup holder on the car, so as to facilitate the relevant adjustment; at the same time, when the lifting structure 2 fails to rise and fall, that is, the driving module 4 fails to work, based on the LIN bus protocol, the fault signal can be fed back to the automobile terminal system, so that the user can understand the fault in time, and some fault codes are displayed to the user for the user to perform simple troubleshooting.

[0069] Furthermore, the control module 3 is communicatively connected to the vehicle terminal system 5 via the in-vehicle LIN communication bus circuit 6, and the control module 3 is a slave node of the in-vehicle LIN communication bus circuit 6;

[0070] The control module 3 includes a control module body 301 for data processing and a LIN transceiver 302 for transmitting and receiving LIN signals. The control module body 301 is connected to the LIN transceiver 302 , and the LIN transceiver 302 is connected to the driving module 4 based on the LIN bus protocol.

[0071] The above structure makes the electric lifting cup holder more reasonable.

[0072] Furthermore, the control module 3 includes an LDO unit 303 for converting an external input voltage into a voltage required by the microprocessor.

[0073] The above structure makes the control module 3 more reasonable; the output end of the LDO unit 303 is externally connected to a filter capacitor and then supplies power to the control module 3, making the power supply of the control module 3 more stable; specifically, the output end of the LDO unit 303 is externally connected to 0.1μF and 10μF filter capacitors and then supplies power to the control module 3.

[0074] Furthermore, the driving module 4 has a first LIN communication port, a first Vbat port and a first GND port, the control module 3 has a second LIN communication port, a second Vbat port and a second GND port, the first LIN communication port and the second LIN communication port are communicatively connected, the first Vbat port and the second Vbat port are both connected to the power supply, and the first GND port and the second GND port are both grounded.

[0075] The above structure makes the driving module 4 and the control module 3 more reasonable.

[0076] Furthermore, the LIN communication protocol between the control module 3 and the drive module 4 includes a LIN control frame and a LIN status frame;

[0077] The driving module 4 is capable of receiving the LIN control frame sent to it by the control module 3, and the driving module 4 controls its working state according to the LIN control frame;

[0078] The driving module 4 can feed back a corresponding LIN status frame to the control module 3 according to its own current status.

[0079] By adopting the above-mentioned method, the communication between the control module 3 and the drive module 4 is made more reasonable, stable and reliable.

[0080] Furthermore, the LIN communication protocol between the control module 3 and the drive module 4 also includes a LIN diagnostic frame.

[0081] In the above manner, the LIN diagnostic frame is used by the drive module 4 to feedback fault and abnormality information to the control module 3, so that the control module 3 can feedback information to the vehicle terminal system 5, so that the vehicle terminal system can feedback and display it to the user.

[0082] Furthermore, the LIN communication protocol between the control module 3 and the drive module 4 can be customized. For example, the manufacturer can use a certain frame in the communication to transmit a certain functional signal.

[0083] By adopting the above-mentioned method, more information can be transmitted between the control module 3 and the drive module 4, so that the manufacturer can add more functions during factory settings, thereby making the electric lifting cup holder more applicable.

[0084] Furthermore, the electric lifting cup holder based on the LIN bus protocol includes a cup holder lifting switch 7; the control module 3 is connected to the cup holder lifting switch 7 to receive the switch signal sent by the cup holder lifting switch 7 and send the corresponding LIN communication signal to the driving module 4 to control the working state of the driving module 4.

[0085] In the above manner, the user can operate the cup holder lifting switch 7 to raise or lower the lifting structure 2. The user can select the desired method to control the electric lifting cup holder, which is convenient for the user to use. Of course, when the lifting structure 2 is controlled by operating the cup holder lifting switch 7, the driving module 4 will also provide feedback to the control module 3, and the control module 3 will provide feedback to the vehicle terminal system 5 to achieve synchronization.

[0086] Typically, the cup holder lifting switch 7 is disposed on the corresponding cup holder body 1 or at a peripheral position thereof for easy operation by the user;

[0087] Specifically, one pin of the cup holder lifting switch 7 is grounded, and the other pin is connected to the control module 3; when the user presses the cup holder lifting switch 7 and lifts it, the control module 3 receives a low-level signal, and the control module 3 sends a corresponding instruction to the drive module 4 according to the signal. For example, when the lifting structure 2 is currently in a high position, the operator presses the cup holder lifting switch 7, and the control module 3 sends a descending instruction to the drive module 4; when the lifting structure 2 is currently in a low position, the operator presses the cup holder lifting switch 7, and the control module 3 sends an ascending instruction to the drive module 4; the cup holder lifting switch 7 can be a mechanical switch, a capacitive switch, or any other type of switch.

[0088] Furthermore, the driving module 4 includes a driving motor 401 and a motor driving unit 402 for controlling and driving the driving motor 401 ; the motor driving unit 402 is connected to the control module 3 in communication based on the LIN bus protocol.

[0089] The above structure makes the driving module 4 more reasonable.

[0090] Furthermore, the driving motor 401 is a stepping motor.

[0091] The above structure makes it easy to control the lifting position of the lifting mechanism, that is, to control the rising or falling distance of the lifting mechanism.

[0092] Furthermore, the electric lifting cup holder based on the LIN bus protocol has a self-learning capability to determine the total up and down movement stroke of the lifting structure 2;

[0093] The self-learning includes: the driving module 4 continuously drives the lifting structure 2 to move up or down until the lifting structure 2 cannot move in this direction to confirm the first endpoint; the driving module 4 drives the lifting structure 2 to move in the opposite direction until the lifting structure 2 cannot move in this direction to confirm the second endpoint, and the distance between the first endpoint and the second endpoint is the total up and down movement stroke of the lifting structure 2.

[0094] By adopting the above method, the total up and down movement stroke of the lifting structure 2 is obtained through self-learning, and the driving module 4 subsequently drives the lifting structure 2 only within the total up and down movement stroke range, that is, between the first end point and the second end point, thereby avoiding the stalling of the driving module 4 during subsequent operation and effectively extending the service life of the driving module 4.

[0095] Furthermore, the control module 3 communicates with the vehicle-mounted terminal system 5 based on the LIN bus protocol and feeds back the total up and down movement stroke of the lifting structure 2 to the vehicle-mounted terminal system 5 .

[0096] By adopting the above method, the vehicle-mounted terminal system 5 can display the total up and down movement stroke of the lifting structure 2 on the vehicle terminal system, so that the user can adjust the lifting position of the lifting structure 2. For example, the percentage adjustment is adopted, that is, the current lifting structure 2 is controlled to move to a certain percentage of the total stroke, making the adjustment more flexible and convenient.

[0097] Furthermore, if the driving module 4 itself does not have a self-learning capability, the control module 3 communicates with the driving module 4 based on the LIN bus protocol to control the operation of the driving module 4, and the control module 3 confirms the first endpoint and the second endpoint based on the stall information fed back by the driving module 4 based on the LIN bus protocol to obtain the total vertical movement stroke of the lifting structure 2; the control module 3 feeds back the total vertical movement stroke of the lifting structure 2 to the on-board terminal system 5 based on the LIN bus protocol;

[0098] If the driving module 4 itself has self-learning capability, the control module 3 sends a self-learning instruction to the driving module 4 based on the LIN bus protocol, and the driving module 4 self-learns to confirm the first endpoint and the second endpoint to obtain the total up and down movement stroke of the lifting structure 2; and the driving module 4 feeds back the total up and down movement stroke of the lifting structure 2 to the control module 3 based on the LIN bus protocol, and the control module 3 then feeds back the total up and down movement stroke of the lifting structure 2 to the on-board terminal system 5 based on the LIN bus protocol.

[0099] With the above structure, even when the electric lifting cup holder uses a driving module 4 that does not have the self-learning capability, it can still achieve its self-learning capability, so that it can be adapted to a wider range of driving modules 4.

[0100] Furthermore, when the driving module 4 is stalled or the lifting structure 2 exceeds the lifting stroke, the self-learning of the electric lifting cup holder based on the LIN bus protocol will be triggered.

[0101] The above-mentioned method makes the triggering mechanism of the self-learning more reasonable.

[0102] Furthermore, the state of the driving module 4 itself includes its current moving position.

[0103] By adopting the above method, the main control chip of the car can obtain the current movement position of the drive module 4; since the on-board terminal system 5 has the ability to store data persistently, when the car starts, the on-board terminal system 5 can control the drive module 4 according to the position information and total stroke information of the drive module 4 stored therein to avoid the drive module 4 from over-moving, that is, stalling; the drive module 4 body in the drive module 4 adopts a stepper motor, so the current movement position of the drive module 4 is the angle information currently output by the stepper motor.

[0104] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0105] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
