Description

Technical Field

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

[0002] LIN (Local Interconnect Network) bus is a low-cost serial communication network defined for automotive distributed electronic systems. It is a supplement to other automotive multi-channel networks such as the Controller Area Network (CAN) and is suitable for applications that do not have high requirements for network bandwidth, performance or fault tolerance. The LIN bus is based on the SCI (UART) data format and adopts a single master controller / multiple slave device mode. It is a special case of UART.

[0003] With the improvement of automobile intelligence and the development of interior design, car owners have increasing requirements for comfort and convenience inside the car. Traditional cup holders are usually fixed and cannot be adjusted at different heights to accommodate beverage containers of different sizes. Therefore, electric lifting cup holders are now available on the market. When beverage containers need to be placed, their lifting structure can be lowered to form a placement space; when they are not needed, their lifting structure can be raised to ensure the flatness of the table surface, which is more beautiful and does not affect the placement of other items on the table surface.

[0004] However, current electric lift cup holders usually have built-in switches to achieve lifting, but usually a car is equipped with multiple electric lift cup holders, which makes the wiring complicated; and in the current era of intelligent automobile development, they are relatively independent and not integrated with the automobile terminal control system, which is inconvenient for users to use and operate. The failure of the electric lift cup holder is also not easy to be detected by users, resulting in motor overheating and damage, etc. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an electric lifting cup holder based on the LIN bus protocol, which realizes communication with the vehicle-mounted 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 object, the present invention adopts the following technical solutions:

[0007] An electric lifting cup holder based on the LIN bus protocol comprises a cup holder main body and a lifting structure capable of performing lifting motion in the cup holder main body. The electric lifting cup holder based on the LIN bus protocol also comprises a control module and a driving module for driving the lifting structure to lift and lower. The control module can be communicatively connected with a vehicle terminal system based on the LIN bus protocol. The control module is communicatively connected with the driving module based on the LIN bus protocol. The control module is used to receive a cup holder lifting signal sent by the vehicle terminal system and send a LIN communication signal to the driving module to control the working state of the driving module.

[0008] By adopting the above structure, the user can directly control the lifting structure in the electric lifting cup holder through the vehicle terminal system; specifically, if the user wants to make the lifting structure rise, 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, the control module sends an ascending instruction to the drive module based on the LIN bus protocol, and the drive module works to drive the lifting structure to rise after receiving the ascending instruction; if the user wants to make the lifting structure fall, 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, the control module sends a descending instruction to the drive module based on the LIN bus protocol, and the drive module works to drive the lifting structure to fall after receiving the descending instruction; the vehicle terminal system 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 to adapt to different types of cups;

[0009] The above structure enables users to more conveniently control the electric lifting cup holder. If the vehicle terminal system is a central control screen of the vehicle, the control can be more intuitive through a graphical interface, 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-mounted terminal system based on the LIN bus protocol.

[0011] 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 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 fails, that is, the driving module 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.

[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 receiving and transmitting LIN signals. The control module body is connected to the LIN transceiver, and the LIN transceiver is connected to the drive module based on a 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 a 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] Further, 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 method, the communication between the control module and the drive module is 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 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 manner, 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 drive module to control the working state of the drive module.

[0028] By adopting the above method, the user can operate the cup holder lifting switch to lift the lifting structure, and the user can choose the current method he wants 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 feedback to the control module, and the control module will feedback to the vehicle terminal system to achieve synchronization;

[0029] Usually, the cup holder lifting switch is arranged on the corresponding cup holder body or its peripheral position, so as to facilitate the user to operate;

[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 lifting or lowering 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, and 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 a 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, so that the adjustment is more flexible and convenient.

[0040] Further, if the driving module itself does not have the 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 according to the stall information fed back by the driving module based on the LIN bus protocol to obtain the total up and down movement stroke of the lifting structure; the control module feeds back the total up and down movement stroke of the lifting structure to the vehicle-mounted 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 feeds back the total up and down movement stroke of the lifting structure to the vehicle-mounted terminal system based on the LIN bus protocol.

[0042] With the above structure, when the electric lifting cup holder uses a driving module 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.

[0043] Furthermore, when the driving module is blocked 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 automobile main control chip 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 automobile is started, 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, so as to avoid the drive module from over-moving, i.e., 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.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[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 also Figures 1 to 3 The present invention provides an electric lifting cup holder based on the LIN bus protocol, comprising a cup holder main body 1 and a lifting structure 2 capable of performing lifting motion in the cup holder main body 1. The electric lifting cup holder based on the LIN bus protocol also comprises a control module 3 and a driving module 4 for driving the lifting structure 2 to lift. The control module 3 can be communicatively connected with a vehicle terminal system 5 based on the LIN bus protocol. The control module 3 is communicatively connected with the driving module 4 based on the LIN bus protocol. The control module 3 is used to receive a cup holder lifting signal sent by the vehicle terminal system 5 and send a LIN communication signal to the driving module 4 to control the working state of the driving module 4.

[0064] By adopting 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, and 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, and the drive module 4 works to drive the lifting structure 2 to rise after receiving the ascending instruction; if the user wants to make the lifting structure 2 fall, the user can perform relevant operations on the vehicle terminal system 5, and 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 drive module 4 works to drive the lifting structure 2 to rise.

[0065] The above structure enables the user to control the electric lifting cup holder more conveniently. If the automobile terminal system is a central control screen of the automobile, the control can be more intuitive through a graphical interface, such as which position of the cup holder to operate. Moreover, since it is based on the LIN bus protocol, the overall wiring can be simplified.

[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 lift, 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 with 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 LIN signal transmission and reception. The control module body 301 is connected to the LIN transceiver 302. The LIN transceiver 302 is connected to the drive 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 a 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 for 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 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 manner, 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 a switch signal sent by the cup holder lifting switch 7 and send a 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 lift the lifting structure 2, and the user can choose the current method he wants to control the electric lifting cup holder, which is convenient for the user's actual use; of course, when the lifting structure 2 is controlled by operating the cup holder lifting switch 7, the driving module 4 will also feedback to the control module 3, and the control module 3 will feedback to the vehicle terminal system 5 to achieve synchronization;

[0086] Usually, the cup holder lifting switch 7 is arranged on the corresponding cup holder body 1 or its peripheral position, so as to facilitate the user to operate;

[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 cup holder lifting switch 7 is pressed, 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 cup holder lifting switch 7 is pressed, 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 a 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 lifting or lowering 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, and 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 blocking of the driving module 4 during subsequent operation, and can effectively extend 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, so that the adjustment is more flexible and convenient.

[0097] Further, if the driving module 4 itself does not have the 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 according to the stall information fed back by the driving module 4 based on the LIN bus protocol to obtain the total up and down movement stroke of the lifting structure 2; the control module 3 feeds back the total up and down movement stroke of the lifting structure 2 to the vehicle-mounted terminal system 5 based on the LIN bus protocol;

[0098] If the driving module 4 itself has the 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 feeds back the total up and down movement stroke of the lifting structure 2 to the vehicle-mounted terminal system 5 based on the LIN bus protocol.

[0099] With the above structure, the electric lifting cup holder can still realize its self-learning capability when using a driving module 4 that does not have the 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 blocked 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 automobile main control chip 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 automobile is started, 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, so as to avoid the drive module 4 from over-moving, i.e., 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 and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0105] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
