[0034] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] The following describes in detail the vehicle turn signal lamp and the vehicle according to the embodiments of the present application in conjunction with the accompanying drawings.

[0037] In order to solve the technical problems that the Bluetooth anchor point is developed as a separate component in the prior art, which leads to high costs, and in order to meet the waterproof and dustproof level, it is necessary to open a separate mold and pay for the mold fee, the vehicle body needs to increase the installation position, which also increases the production cost in disguise, and it is necessary to add a separate power supply harness and communication harness, the embodiment of the utility model integrates the Bluetooth anchor point into the side turn signal of the current vehicle as a component. Therefore, there is no need to develop the Bluetooth anchor point as a separate component. In addition, there is no need to open a separate mold to meet the waterproof and dustproof level, which causes high costs. By using the current turn signal housing, while meeting the waterproof and dustproof requirements, there is no need to add a separate installation position, and by using the existing power supply harness of the lamp, the function of the Bluetooth anchor point can be realized by simply adding a communication harness. Furthermore, it has the advantages of low cost, safety and reliability, and does not require additional installation space. The specific implementation is as follows:

[0038] Figure 1 FIG. 1 is a structural block diagram of a vehicle turn signal lamp according to an embodiment of the present application. Figure 1 As shown, the vehicle turn signal lamp 100 according to the embodiment of the present application specifically includes: a driving circuit 110, a Bluetooth module 120, a CAN transceiver 130, a power supply circuit 140 and a turn signal lamp housing 150, wherein:

[0039] The driving circuit 110 is connected to the power supply circuit of the turn signal. The Bluetooth module 120 is connected to the driving circuit 110 to control the on and off of the power supply circuit through the driving circuit 110 according to the turn signal on and off signal, and detect the field strength value of the remote control key. The CAN transceiver 130 is connected to the Bluetooth module 120 to send the turn signal on and off signal to the Bluetooth module 120, and forward the field strength value to the CAN network. The power supply circuit 140 is respectively connected to the power supply circuit 110, the Bluetooth module 120 and the CAN transceiver 130 to supply power to the power supply circuit 110, the Bluetooth module 120 and the CAN transceiver 130. The driving circuit 110, the Bluetooth module 120, the CAN transceiver 130 and the power supply circuit 140 are arranged in the turn signal housing 150, that is, the driving circuit 110, the Bluetooth module 120, the CAN transceiver 130 and the power supply circuit 140 are all arranged in the turn signal housing.

[0040] In a specific example, if Figure 2As shown, the driving circuit 110 includes: a switch 111 and a switch control circuit 112, wherein the switch 111 is arranged in the power supply circuit of the turn signal lamp 160. The switch control circuit 112 is connected to the switch 111 to control the on and off of the switch 111. For example, when the turn signal lamp 160 is on, the switch control circuit 112 controls the switch 111 to be closed, so that the power supply circuit of the turn signal lamp 160 is turned on, so that the turn signal lamp 160 is turned on; conversely, when the turn signal lamp 160 is off, the switch control circuit 112 controls the switch 111 to be disconnected, so that the power supply circuit of the turn signal lamp 160 is disconnected, so that the turn signal lamp 160 is turned off.

[0041] In this example, the switch 160 is but not limited to a relay. Taking a relay as an example, the control end of the relay is connected to the switch control circuit 112, so that the switch control circuit 112 controls the on and off of the relay by inputting high and low level signals to the control end of the relay.

[0042] In one embodiment of this invention, if Figure 2 As shown, the Bluetooth module 120 includes: a Bluetooth chip 121 and a Bluetooth antenna 122, wherein the Bluetooth chip 121 is connected to the CAN transceiver 130 and the drive circuit 110 respectively, so as to control the on and off of the power supply circuit of the turn signal 160 through the drive circuit 110 when receiving the turn signal on and off signal sent by the CAN transceiver 130, and when detecting the field strength value of the Bluetooth signal sent by the remote control key (i.e., such as the Bluetooth key of the vehicle), the field strength value is sent to the CAN transceiver 130. The Bluetooth antenna 122 is connected to the Bluetooth chip 110.

[0043] In a specific example, the Bluetooth antenna 122 is but not limited to a PCB (Printed Circuit Board) onboard antenna, which is a highly integrated antenna that prints the antenna directly on the PCB board, thereby achieving the purpose of simplicity, efficiency and convenience. The field strength value is RSSI (Received Signal Strength Indication), which refers to: received signal strength indication, an optional part of the wireless transmission layer, used to determine the link quality and whether to increase the broadcast transmission strength. Generally speaking, the distance between the remote control key and the Bluetooth module 120 can be approximately considered to be proportional to the RSSI value, that is, the larger the RSSI value, the closer the distance between the remote control key and the Bluetooth module 120, and vice versa, the farther the distance between the remote control key and the Bluetooth module 120.

[0044] Combination Figure 2As shown, the power supply circuit 140 includes: a power supply pin 141 and a DC / DC conversion circuit 142. The DC / DC conversion circuit 142 is respectively connected to the power supply pin 141, the power supply circuit, the Bluetooth module 120 and the CAN transceiver 130, so as to convert the voltage signal sent by the power supply pin 141 into voltage signals matching the power supply circuit, the Bluetooth module 120 and the CAN transceiver 130, and then supply power to the power supply circuit, the Bluetooth module 120 and the CAN transceiver 130.

[0045] Generally speaking, the power supply circuit (i.e., the turn signal 160 in the power supply circuit), the Bluetooth module 120, and the CAN transceiver 130 use different voltages for power supply. Therefore, the DC / DC conversion circuit 142 may include: a first conversion module, which is connected to the power supply circuit to convert the voltage signal of the power supply pin 141 into a voltage signal that matches the power supply circuit; a second conversion module, which is connected to the Bluetooth module 120 to convert the voltage signal of the power supply pin 141 into a voltage signal that matches the Bluetooth module 120; and a third conversion module, which is connected to the CAN transceiver 130 to convert the voltage signal of the power supply pin 141 into a voltage signal that matches the CAN transceiver 130. Figure 2 As shown, the voltage signal required in the power supply circuit is a 24V DC voltage, the voltage signal required by the CAN transceiver 130 is a 5V DC voltage, and the voltage signal required by the Bluetooth module 120 is a 3.3V DC voltage.

[0046] Combination Figure 1 and Figure 2 As shown, the turn signal lamp of the vehicle in the embodiment of the utility model, the Bluetooth module 120 receives the command (i.e., the instruction to control the turn signal on and off, such as the turn signal on and off signal) through the CAN transceiver 130, and then controls the turn signal 160 to be on and off through the driving circuit 110. And the Bluetooth module 120 can send the measured RSSI value of the remote control key to the CAN bus through the CAN transceiver 130 so that the Bluetooth master node can know it. That is, in the embodiment of the utility model, the Bluetooth anchor point (i.e., the Bluetooth module 120) is integrated into the side turn signal lamp of the current vehicle as a component. Therefore, there is no need to develop the Bluetooth anchor point as a separate component. In addition, there is no need to open a separate mold to meet the waterproof and dustproof level, which causes high cost. The current turn signal housing is used to meet the waterproof and dustproof requirements without adding a separate installation position, and the existing power supply harness of the lamp is used. Simply adding a communication harness can realize the function of the Bluetooth anchor point. Furthermore, it has the advantages of low cost, safety and reliability, and does not require additional installation space.

[0047] Combination Figure 2 As shown, the vehicle turn signal lamp may further include: a sampling circuit 170 , wherein the sampling circuit 170 is respectively connected to the power supply circuit and the Bluetooth module 120 to collect the voltage value on the power supply circuit and send the voltage value to the Bluetooth module 120 .

[0048] In a specific example, the sampling circuit 170 is, for example, an AD sampling circuit. That is, the Bluetooth module 120 can measure the voltage value V1 through the AD sampling circuit, and by comparing the value of V1, it can be diagnosed whether the turn signal lamp 160 has a fault. For example, when the turn signal lamp 160 is short-circuited, V1 is close to 24V, and when the turn signal lamp 160 is open-circuited, V1 is close to 0V. Thus, the fault detection of the turn signal lamp can be realized simply and conveniently, and the convenience and efficiency of the fault detection of the turn signal lamp can be effectively improved.

[0049] According to the vehicle turn signal lamp of the embodiment of the utility model, the function of the Bluetooth anchor point is integrated with the function of the turn signal lamp, and is installed in the turn signal lamp cover (housing), which utilizes the existing turn signal lamp cover shell, does not need to redesign the Bluetooth anchor point, and reduces the development cost. In addition, the installation position of the Bluetooth anchor point does not need to be added again on the vehicle body, and the current installation position of the turn signal lamp is utilized, which effectively saves space. The wiring harness utilizes the power wiring harness of the original turn signal lamp, and usually the function of the Bluetooth anchor point can be realized by simply adding a CAN communication wiring harness, thereby having the advantages of simple and convenient wiring harness layout and low cost.
