[0031] <Example>
[0032] The vehicle-mounted Ethernet high-speed data communication electronic and electrical architecture of this embodiment is applied to a vehicle-mounted Ethernet high-speed data communication terminal. The vehicle-mounted Ethernet high-speed data communication terminal realizes data interaction between the vehicle and the host computer (ie, the terminal) through the above electronic and electrical architecture.
[0033] Figure 1 A structural block diagram of the vehicle-mounted Ethernet high-speed data communication electronic and electrical architecture provided by an embodiment of the utility model, Figure 2 This is a schematic diagram of the structure of the vehicle-mounted Ethernet high-speed data communication terminal provided by the embodiment of the utility model. Figure 1 The vehicle Ethernet high-speed data communication electronic and electrical architecture 20 specifically includes a data transmission interface 210, a power interface 220, a processing module 230, a power conversion module 240, a button 250 and an indicator light 260. Figure 2 The corresponding vehicle Ethernet high-speed data communication terminal 10 has the above-mentioned vehicle Ethernet high-speed data communication electronic and electrical architecture 20 and further includes a skeleton body 110 and a shell 120. The specific structure is described as follows:
[0034] The data transmission interface 210 includes a vehicle-side interface 211 and a terminal-side interface 212. The vehicle-side interface 211 is used to connect to the vehicle under test, and the terminal-side interface 212 is used to connect to a host computer (such as a computer or other equipment), so that the host computer can exchange data with the vehicle.
[0035] As an implementation form, the vehicle-side interface 211 and the terminal-side interface 212 are both Ethernet interfaces that support more than two transmission rates. In this embodiment, the vehicle-side interface 211 includes an interconnected vehicle-mounted connector 2111 and a vehicle-side network card chip 2112, which needs to support at least 100Mbit / s and 1000Mbit / s transmission rates, specifically, it can be an on-board Ethernet connector TE MATEnet (i.e., an on-board 1000base-T1 connector) and a 100 / 1000base-T1PHY network card chip; the terminal-side interface 212 includes an interconnected universal connector 2121 and a terminal-side network card chip 2122, which needs to support at least 100Mbit / s and 1000Mbit / s transmission rates, specifically, it can be an RJ45 connector and a 100 / 1000base-TX PHY network card chip.
[0036] In particular, the vehicle-side network card chip 2112 and the terminal-side network card chip 2122 are connected through bus communication, and the two transmit MII signals through the bus to form a data transparent transmission channel. In this embodiment, the data transparent transmission channel can have a transmission rate of 100M or 1000M, so that a large amount of high-speed data can be transmitted between the vehicle and the host computer.
[0037] The power interface 220 is a Type-C interface. In this embodiment, the Type-C interface serving as the power interface 220 does not support data transmission and is only used to support an external power source for power supply.
[0038] The processing module 230 is an ARM processor.
[0039] In this embodiment, the processing module 230 is electrically connected to the vehicle-side network card chip 2112 and the terminal-side network card chip 2122, respectively, and is used to determine the transmission rate of the vehicle-side interface 211 and the terminal-side interface 212 according to the connection signal when the vehicle-side interface 211 is connected to the vehicle. Specifically, when the vehicle-side interface 211 and the terminal-side interface 212 establish a connection with the vehicle and the host computer, the processing module 230 obtains the maximum transmission rate supported by the vehicle from the vehicle-side network card chip 2112, and sends the corresponding signal to the two network card chips according to the maximum transmission rate to complete the adaptive matching of the transmission rate.
[0040] The power conversion module 240 is electrically connected to the processing chip 231, the vehicle-side network card chip 2112 and the terminal-side network card chip 2122 respectively, and is used to convert the input voltage of the power interface 220 to adapt it to the working voltage of the processing chip (processing module 230) and the network card chip and provide it to each other.
[0041] As an implementation form, the power interface is a Type-C interface that can support voltages of 5V to 30V. This method is convenient for users to use. Specifically, compared with the traditional power supply method, it saves users the time of looking for a socket. Generally, users who perform vehicle diagnosis or testing can directly connect the Type-C data cable to the host computer used in the test to obtain power.
[0042] As another embodiment, the operating voltage of the processing chip 231 can be 3.3V, and the operating voltage of the network card chip can be 1.8V. After the power conversion module 250 completes the conversion, each operating voltage is output to the corresponding electrical appliance to complete the power supply. In addition, in this embodiment, the overall power consumption of the entire vehicle data communication electronic and electrical architecture 20 is 1.5W-2.5W, which is relatively low.
[0043] The buttons 250 include a rate switching button 251 , a master-slave switching button 252 , and a connection button 253 .
[0044] The indicator lights 260 correspond one-to-one to the buttons 250. In this embodiment, the indicator lights 260 have two display states, for example, a green light state and a yellow light state, and are used to indicate the working state of the corresponding button 250 by alternating the two display states.
[0045] Specifically, the rate switching button 251 is used to make the processing module 15 send a signal to the two network card chips to switch their transmission rates when pressed. The indicator light 260 corresponding to the rate switching button 251 can indicate that the current transmission rate is 1000M by turning on the green light constantly, and the current transmission rate is 100M by turning on the yellow light constantly.
[0046] The master-slave switch button 252 is used to make the processing module 15 send a signal to the two network card chips to switch their master-slave modes when pressed. The indicator light 260 corresponding to the rate switch button 251 can indicate the current master mode (Master) by turning on the green light constantly, and the current slave mode (Slave) by turning on the yellow light constantly.
[0047] The connection button 253 is used to make the processing module 15 automatically match the transmission rate and master-slave mode of the two network card chips when pressed. The indicator light 260 corresponding to the rate switching button 251 can indicate a normal connection by a green light that is always on, indicate data communication by flashing the green light (i.e., alternating display), and indicate a data communication error by flashing the yellow light (i.e., alternating display).
[0048] The above is a detailed description of the vehicle Ethernet high-speed data communication electronic and electrical architecture 20. Next, the vehicle Ethernet high-speed data communication terminal 10 using the above architecture is described in detail:
[0049] The skeleton body 110 includes a first skeleton 111, a second skeleton 112, a first fixing assembly 113, a first substrate 114 and a second substrate 115 (refer to Figure 4 , Figure 5 and Figure 6 ).
[0050] The first frame 111 and the second frame 112 are used to form the main frame of the vehicle-mounted data communication terminal 10. The data transmission interface 210, the power interface 220, the processing module 230, the button 250 and the indicator light 260 are all fixed between the first frame 111 and the second frame 112.
[0051] The fixing assembly 113 is used to fix the first frame 111 , the second frame 112 , the housing 120 and the processing module 230 .
[0052] The first substrate 114 and the second substrate 115 are used to fix the data transmission interfaces 210 , the power interface 220 and the indicator lights 260 .
[0053] The housing 120 is disposed on the skeleton body 110 and includes an outer housing 121 and a side housing 122. Figure 2 ,in:
[0054] The outer shell 121 includes a first plate 1211, a second plate 1212 and a ridge 1213 which are integrally formed. Figure 3 The first plate 1211 and the second plate 1212 are arranged opposite to each other and cooperate to form a shell structure capable of clamping the skeleton body 110.
[0055] In this embodiment, the ridge 1213 is in an arc transition state, so that the cross-section of the entire outer shell 121 is U-shaped, thereby improving the structural strength and aesthetics of the outer shell. It is understandable that in an alternative solution, the ridge of the outer shell can also be set to a straight ridge structure or other shapes, which can also ensure the basic function of the ridge connecting the first plate 1211 and the second plate 1212.
[0056] In particular, if Figure 2 As shown, the edge of the side shell 122 close to the outer shell 121 is formed with a protrusion 1224 in a direction perpendicular to the surface of the outer shell 121, so that the height of the outer surface of the outer shell 121 in a direction parallel to the surface of the outer shell 121 is lower than the protrusion 1224. In this way, the wear and tear on the surface of the outer shell 121 when the entire in-vehicle Ethernet high-speed data communication terminal 10 is used can be reduced.
[0057] As an implementation method, refer to Figure 3 and Figure 4 In order to fix the outer shell 121 to the skeleton body 110, the first skeleton 111 is provided with two first guide grooves 1111 extending along the first direction, and the first plate 1211 is provided with a first guide head 1214 matched with the first guide grooves 1111 on a surface contacting the first skeleton 111. Figure 3 and Figure 5 The second frame 112 is provided with two second guide grooves 1121 extending in the first direction, and the second plate 1212 is provided with a second guide head 1215 matched with the second guide grooves 1121 on a surface contacting the second frame 112. Through the first guide grooves 1111 and the second guide grooves 1121, the frame body 110 can be slidably embedded in the outer shell 121 along the first direction. In addition, after the frame body 110 is embedded, the first plate 1211 and the second plate 1212 of the outer shell 121 can limit the movement of the first frame and the second frame in the third direction.
[0058] As another embodiment, refer to Figure 3 and Figure 4 A buckle portion 1112 is further provided between the two first guide grooves 1111 of the first frame 111, and a buckle head 1216 matching with the buckle portion 1112 is provided on a surface of the first plate 1211 that contacts the first frame 111. When the frame body 110 slides along the first direction and is embedded in the outer shell 121, the buckle portion 1112 and the buckle head 1216 cooperate with each other to limit the movement of the outer shell 121 relative to the frame body 110 in the first direction, that is, to limit the outer shell 121 from coming out of the frame body 110.
[0059] At the same time, reference Figure 3 and Figure 4 , two clamping parts 1113 are also provided on the first frame 111, and two clamping joints 1217 matched with the clamping parts 1113 are provided on the side of the ridge 1213 that contacts the first frame 111. Similar to the bayonet part 1112, the clamping parts 1113 and the clamping joints 1217 are also used to limit the movement of the outer shell 121 relative to the frame body 110 in the first direction, that is, to clamp the two when the frame body 110 is embedded in the outer shell 121. In addition, the clamping part 1113 is also used to apply a force to the clamping joints 1217 in a direction away from the first plate body 1211, so that the clamping joints 1217 cooperate with the first plate body 1211 to fix the outer shell 121 on the first frame 111. Specifically, when the outer shell 121 tries to escape from the first frame 111, the clamping joints 1217 and the first plate body 1211 will be subjected to relative forces respectively, thereby limiting the escape of the outer shell 121.
[0060] The side housing 122 includes an integrally formed third plate 1221, a fourth plate 1222 and a middle plate 1223. The third plate 1221 and the fourth plate 1222 are arranged opposite to each other. The data transmission interfaces 210 are distributed on the third plate 1221 and the fourth plate 1222. There is an arc transition between the third and fourth plates and the middle plate.
[0061] In this embodiment, the outer shell 121, the side shell 122, the first frame 111, and the second frame 112 cooperate to form a closed shell structure. The five plates of the outer shell 121 and the side shell 122 correspond to the five surfaces of the vehicle-mounted data communication terminal 10. The first direction is a direction perpendicular to the surface of the middle plate 1223, the second direction is a direction in which the third plate 1221 and the fourth plate 1222 are opposite, and the third direction is a direction in which the first plate 1211 and the second plate 1212 are opposite. The first, second, and third directions are perpendicular to each other.
[0062] In addition, refer to Figure 6 , the data transmission interface 210, the power interface 220 and the processing module 230 are all fixed on the first substrate 114. The button 250 and the indicator light 260 are fixed on the second substrate 115. The second substrate 115 is perpendicular to the first substrate 114 and parallel to the middle plate 1223, so that the button 250 and the indicator light 260 are fixed in the corresponding openings on the middle plate 1223. The second substrate 115 can be fixed to the first substrate 114 by adhesion, or by bolts, clamping or other methods.
[0063] The above is a specific description of the vehicle-mounted Ethernet high-speed data communication terminal 10 of this embodiment. It should also be noted that in the specific implementation process, the vehicle-mounted Ethernet high-speed data communication terminal 10 and the electronic and electrical architecture 20 may also include other components necessary for normal operation. In addition, it can be understood by those skilled in the art that the above-mentioned vehicle-mounted Ethernet high-speed data communication terminal 10 and the electronic and electrical architecture 20 may also only include the components necessary to implement the embodiment of the present application, and do not necessarily include all the components shown in the figure.
[0064] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited thereto.
