Description

Technical Field

[0001] This utility model relates to the technical field of autonomous vehicle testing equipment, and in particular to a power supply device for a sensing device used in autonomous vehicle testing. Background Technology

[0002] Autonomous vehicles, also known as driverless vehicles, are vehicles that rely on cameras and radar to perceive road conditions and, through the collaboration of artificial intelligence and global positioning systems, enable onboard computers to drive automatically and safely without the active operation of a driver.

[0003] To ensure the safety of autonomous driving, numerous tests are required on autonomous vehicles to verify the performance of cameras and radar, as well as to train and validate artificial intelligence systems. During routine autonomous driving testing and data collection, many sensors need to be installed on the vehicle to collect and record various types of data. Currently, in autonomous vehicles undergoing testing, these sensors are typically directly connected to the vehicle's battery for power.

[0004] The existing power supply method has several drawbacks. First, since the sensing devices rely on the vehicle's battery for power, without power management, the sensing devices will continue to operate even when the vehicle is in sleep mode. This not only wastes energy and can easily damage the battery, but also affects the normal use of the vehicle if the battery is depleted. Second, it is also prone to accidental operation that could cause other devices to lose power, resulting in data loss, which is detrimental to ensuring the reliability of the power supply for the vehicle's sensing devices. Utility Model Content

[0005] In view of this, the present invention aims to provide a power supply device for sensing equipment used in testing autonomous vehicles, which can overcome at least one of the shortcomings of the prior art and has better practicality.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A power supply device for a sensor used in testing autonomous vehicles includes a power supply box and a plurality of electrical connection ports disposed on the power supply box.

[0008] The plurality of electrical connection ports include a first electrical connection port for connecting to a KL30 power supply in the vehicle, a second electrical connection port for connecting to a KL15 power supply in the vehicle, and a third electrical connection port for connecting to a sensing device.

[0009] An electrical connection is formed between the third electrical connection port and the first electrical connection port, and a control switch is provided on the power supply box. The control switch is used to control the connection between the third electrical connection port and the first electrical connection port.

[0010] The second electrical connection port is connected to the coil of the relay located in the power supply box. The contacts of the relay are connected in series between the first electrical connection port and the control switch. When the second electrical connection port is connected to the KL15 power supply, the contacts engage to conduct electricity between the first electrical connection port and the control switch.

[0011] Furthermore, the power supply box is equipped with a first indicator light;

[0012] The first indicator light is electrically connected to the first electrical connection port, and the first indicator light is lit when the first electrical connection port is connected to the power supply of the KL30.

[0013] Furthermore, there are multiple third electrical connection ports arranged at intervals on the power supply box, and a control switch is provided for each of the third electrical connection ports.

[0014] Furthermore, the power supply box is equipped with a second indicator light;

[0015] The second indicator light consists of multiple lights arranged in a one-to-one correspondence with the third electrical connection port, and each second indicator light is connected to the corresponding third electrical connection port.

[0016] Furthermore, each of the third electrical connection ports and the corresponding control switches are connected in series with fuses, and each of the second indicator lights is connected between the corresponding fuse and the third electrical connection port.

[0017] Furthermore, a voltage regulator is provided inside the power supply box;

[0018] The contacts of the relay are connected to the input terminal of the voltage regulator, and each of the control switches is connected in parallel to the output terminal of the voltage regulator.

[0019] Furthermore, the first electrical connection port and the second electrical connection port are located on one side wall of the power supply box, and the plurality of the third electrical connection ports are located on the other side wall of the power supply box.

[0020] Furthermore, at least one of the first electrical connection port, the second electrical connection port, and the third electrical connection port adopts a banana plug socket; and / or,

[0021] The first electrical connector is a different color from the second electrical connector.

[0022] Furthermore, the bottom of the power supply box is provided with mounting holes for installing the power supply box into the vehicle.

[0023] Furthermore, a mounting assembly is provided at the mounting hole, through which the power supply box is mounted to the vehicle, and the mounting assembly is configured to buffer the transmission of vibrations from the vehicle to the power supply box.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] The power supply device for the sensing equipment used in testing autonomous vehicles according to this utility model has a first electrical connection port connected to the KL30 power supply in the vehicle and a second electrical connection port connected to the KL15 power supply in the vehicle. The second electrical connection port is connected to the coil of a relay, and the contacts of the relay are connected in series between the first electrical connection port and the control switch. When the second electrical connection port is connected to the KL15 power supply, the contacts are closed to conduct electricity between the first electrical connection port and the control switch. Therefore, it can avoid the waste of electrical energy and damage to the battery caused by the sensing equipment working continuously when the vehicle is in sleep mode. In particular, it can avoid the impact on the normal use of the vehicle due to the depletion of the battery. Thus, it not only overcomes at least one of the shortcomings of the prior art, but also has good practicality.

[0026] Furthermore, indicator lights on the power supply box clearly show the circuit's on / off status, reducing the likelihood of misoperation. Multiple, spaced-apart third electrical connection ports connected to the sensing devices, each with its own control switch, allow for individual control of power supply to different sensing devices. This helps prevent power outages to other devices due to misoperation, leading to data loss and ensuring the reliability of power supply to the vehicle-mounted sensing devices.

[0027] In addition, by installing fuses, the circuit can be promptly disconnected to protect the sensing device in the event of a short circuit. A voltage regulator ensures the power supply quality for the sensing device, allowing it to operate at its best. Placing the first and second electrical connection ports on one side wall of the power supply box, and multiple third electrical connection ports on the other side wall, allows for better differentiation of different circuits and facilitates wiring. Using banana-shaped connectors for the electrical connection ports facilitates connection to the power supply box. Using different colors for the first and second electrical connection ports helps prevent incorrect wiring. Installing mounting components at the mounting holes buffers the transmission of vehicle vibrations to the power supply box, helping to prevent the electrical connection ports from becoming loose due to vibration.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] This embodiment relates to a power supply device for sensing equipment used in testing autonomous vehicles. It is installed on the autonomous vehicle to supply power to sensing equipment such as cameras, radars, and industrial control computers in the vehicle when the autonomous vehicle is being tested.

[0044] In terms of overall structure, combined Figures 1 to 4 As shown, the power supply device for the sensor equipment used in the test of autonomous vehicles in this embodiment includes a power supply box 100 and a plurality of electrical connection ports provided on the power supply box 100.

[0045] The multiple electrical connection ports include a first electrical connection port 1 for connecting to the power supply of KL30 in the vehicle, a second electrical connection port 2 for connecting to the power supply of KL15 in the vehicle, and a third electrical connection port 3 for connecting to the sensing device.

[0046] An electrical connection is formed between the third electrical connection port 3 and the first electrical connection port 1, and a control switch 4 is provided on the power supply box 100. The control switch 4 is used to control the connection between the third electrical connection port 3 and the first electrical connection port 1.

[0047] The second electrical connection port 2 is connected to the coil of the relay K1 located in the power supply box 100. The contacts of the relay K1 are connected in series between the first electrical connection port 1 and the control switch 4. When the second electrical connection port 2 is connected to the power supply of KL15, the contacts of the relay K1 are engaged to conduct electricity between the first electrical connection port 1 and the control switch 4.

[0048] At this time, as set up above, when the second electrical connection port 2 is connected to the KL15 power supply in the vehicle, the contacts of the relay K1 will close to connect the first electrical connection port 1 and the control switch 4, thus connecting the third electrical connection port 3 and the first electrical connection port 1 to supply power to the sensing device. Therefore, this embodiment can avoid the waste of power and damage to the battery caused by the continuous operation of the sensing device when the vehicle is in sleep mode. In particular, it can avoid the impact on the normal use of the vehicle due to the depletion of the battery power, thus avoiding the shortcomings of the prior art.

[0049] Based on the above overview, it's worth noting that KL30 and KL15 are two common power lines in vehicles. KL30 represents the vehicle battery, also known as Vbat power, and it is always connected to the vehicle battery, unaffected by the ignition switch, providing a stable power supply to the vehicle's electrical components. Corresponding to KL30, vehicles typically also have KL31, which is the negative terminal of the vehicle battery, i.e., ground. Unlike KL30, which is always powered, KL15 is connected to the ignition switch and is only powered when the ignition switch is turned on.

[0050] As described above, vehicles typically have both KL30 and KL31 installed simultaneously. Therefore, the first electrical connection port in this embodiment specifically includes a KL30 interface 101 and a KL31 interface 102. The KL30 interface 101 is used to connect to the KL30 in the vehicle, and the KL31 interface 102 is used to connect to the KL31 in the vehicle. The second electrical connection port 2, used to connect to the KL15 in the vehicle, only needs to be provided once since it is only used to control the relay K1.

[0051] Furthermore, similar to the first electrical connection port 1, the third electrical connection port 3 in this embodiment, which connects to the sensing device, also consists of a positive interface 301 and a negative interface 302, used to connect the positive and negative power supply terminals of the sensing device, respectively. Within the power supply box 100, the positive interface 301 of the third electrical connection port 3 can form an electrical connection with the KL30 interface 101 of the first electrical connection port 1, thus establishing a power supply circuit between the vehicle's battery and the sensing device. The negative interface 302 of the third electrical connection port 3, as well as the negative-side circuits such as the aforementioned KL31 interface 102, are simply grounded.

[0052] In this embodiment, see continue to refer to Figure 1 and 2 As shown in the illustration, in a specific implementation, the power supply box 100 of this embodiment can be, for example, an injection-molded plastic part, which not only has a lighter weight but also provides better insulation. Structurally, the power supply box 100 generally consists of a lower box body and a cover plate connected to the top of the lower box body. After all the electrical components inside the power supply box 100 are arranged, the cover plate can be fixed to the lower box body using conventional connection methods such as snap-fit ​​or screw connection.

[0053] In addition, as Figures 1 to 4 As shown, in a preferred embodiment, a first indicator light 5 is provided on the power supply box 100. The first indicator light 5 is electrically connected to the first electrical connection port 1, and the first indicator light 5 is lit when the first electrical connection port 1 is connected to the KL30 power supply, thereby indicating the connection status between the first electrical connection port 1 and the KL30 power supply.

[0054] In specific implementation, the first indicator light 5 is preferably an LED light, and it can be... Figure 3 and Figure 4 The circuit configuration is as follows. It is understandable that by setting the first indicator light 5 on the power supply box 100, the on / off status between the power supply box 100 and the KL30 power supply in the vehicle can be clearly indicated, which can reduce the occurrence of misoperation.

[0055] In this embodiment, as a preferred implementation, the aforementioned third electrical connection port 3 can generally be a plurality of ports spaced apart on the power supply box 100, and a control switch 4 is provided for each third electrical connection port 3.

[0056] At this point, it is understood that by having multiple third electrical connection ports 3 connected to the sensing devices arranged at intervals, and by setting control switches 4 for each third electrical connection port 3, this embodiment can realize separate control of the power supply to different sensing devices, which helps to avoid problems such as power outages to other devices due to misoperation, resulting in data loss, and thus helps to ensure the reliability of the power supply to the vehicle-mounted sensing devices.

[0057] In specific implementation, the control switch 4 mentioned above can be, for example, a push-button switch installed on the power supply box 100. Of course, in addition to push-button switches, the control switch 4 in this embodiment can also be other conventional switch components that can perform on / off control.

[0058] In addition, similar to the arrangement of the first indicator light 5 described above, as a preferred embodiment, a second indicator light 6 may also be provided on the power supply box 100. Multiple second indicator lights 6 are arranged in a one-to-one correspondence with the third electrical connection port 3, and each second indicator light 6 is connected to its corresponding third electrical connection port 3.

[0059] In specific implementation, each of the aforementioned second indicator lights 6 can preferably be an LED light, and it can also be... Figure 3 and Figure 4 The circuit configuration is set accordingly. Furthermore, by providing the aforementioned second indicator lights 6 on the power supply box 100, it is understood that this embodiment can clearly indicate the on / off status of the power supply circuit to the connected sensing components, and can also reduce the occurrence of operator errors.

[0060] In this embodiment, see still Figure 3 and Figure 4 As shown in the diagram, in a preferred embodiment, fuses can be connected in series between each third electrical connection port 3 and its corresponding control switch 4, and each second indicator light 6 is also connected between its corresponding fuse and the third electrical connection port 3. The fuses corresponding to each third electrical connection port 3 are FH1-FH6 in the diagram. By installing fuses in the circuit of each third electrical connection port 3, it is understood that they can promptly disconnect the circuit to protect the sensing device in the event of a short circuit.

[0061] In this embodiment, also as a preferred implementation, in addition to the aforementioned fuse, a voltage regulator U1 can be further installed in the power supply box 100. Specifically, the voltage regulator U1 can be a readily available product of suitable specifications. Furthermore, within the power supply box 100, the contacts of the relay K1 are connected to the input terminal of the voltage regulator U1, and each control switch 4 is connected in parallel to the output terminal of the voltage regulator U1. Moreover, by installing the voltage regulator U1, it is understood that it can ensure the power supply quality of the sensing device, enabling the sensing device to operate in a better state.

[0062] Continue to refer Figure 1 and Figure 2 As shown, in specific implementation, the power supply box 100 of this embodiment can generally adopt a square structure, and preferably, the first electrical connection port 1 and the second electrical connection port 2 can be located on one side wall of the power supply box 100, while the plurality of third electrical connection ports 3 can be located on the other side wall of the power supply box 100.

[0063] In this way, the first electrical connection port 1 and the second electrical connection port 2, which are used to connect to the power supply in the vehicle, are located on one side wall of the power supply box 100, while the multiple third electrical connection ports 3, which are used to connect to the sensing device, are located on the other side wall of the power supply box 100. Obviously, this can better distinguish the circuits for different purposes, facilitate wiring operations, and help avoid misoperation.

[0064] In this embodiment, as a preferred implementation, the first electrical connection port 1, the second electrical connection port 2, and the third electrical connection port 3 can all be banana plug sockets. In this case, the terminals of each power cord connected to the power supply box 100 can all be configured as banana plugs, and the use of banana plug sockets for each electrical connection port facilitates electrical connection with the power supply box 100, improving the convenience of connection operations.

[0065] However, in addition to using banana plug sockets, it is also possible in some other embodiments to use other conventional connection structures such as screw connections or clamping methods for all or part of the electrical connection ports of this embodiment, and there is no limitation on this.

[0066] In a preferred embodiment, the colors of the first electrical connection port 1 and the second electrical connection port 2 can be set to be different. This difference in color helps prevent incorrect connection of KL30 and KL15, facilitating the connection operation of the power supply box 100. In a specific implementation, as an example, the KL30 interface 101 and KL31 interface 102 in the first electrical connection port 1 can both be set to red, while the second electrical connection port 2 can be set to black.

[0067] In this embodiment, since the power supply box 100 needs to be installed in the vehicle, in order to facilitate its arrangement in the vehicle, as a preferred embodiment, a mounting hole 7 for installing the power supply box 100 into the vehicle can be provided at the bottom of the power supply box 100.

[0068] The aforementioned mounting holes 7 can generally be arranged in multiple configurations around the power supply box 100. In specific implementations, for example, the power supply box 100 can be directly fastened to the vehicle using screws. However, in addition to direct screw fixing, as a preferred embodiment, this embodiment can also provide a mounting component 8 at the mounting holes 7, allowing the power supply box 100 to be mounted to the vehicle via the mounting component 8. Simultaneously, the mounting component 8 is also configured to buffer the transmission of vibrations from the vehicle to the power supply box 100.

[0069] Therefore, by providing the mounting component 8 at the mounting hole 7, it can be understood that it can buffer the transmission of vibrations from the vehicle to the power supply box 100, which helps to prevent the electrical connection from becoming loose due to vibration. Moreover, this design is particularly advantageous in ensuring the reliability of the connection at each electrical connection point when the electrical connection in this embodiment adopts a banana plug type connector.

[0070] In practical implementation, the aforementioned mounting component 8 can adopt any existing structure that is suitable in specification and can serve as a connection and vibration buffer. And as an example, combined with... Figure 5 As shown, the mounting assembly 8 in this embodiment may structurally include, for example, a housing and a piston 804 slidably disposed within the housing. The piston 804 divides the housing into upper and lower cavities, both of which are filled with damping fluid. The piston 804 also has a damping hole 8041 connecting the two cavities, and springs are provided on both the upper and lower sides of the piston 804. Furthermore, an upper connecting post 803 with one end extending out of the housing is provided on one side of the piston 804, and a lower connecting post 807 is provided at the bottom of the housing.

[0071] The aforementioned housing can be made of conventional materials such as metal or plastic, as long as it meets the corresponding requirements for structural strength. Structurally, the housing specifically includes an outer shell 801 and an end cap 802 connected to one end of the outer shell 801. In a specific implementation, after a piston 804 and a spring are placed in the outer shell 801, the outer shell 801 and the end cap 802 can be fixed together, for example, by welding, to prevent leakage of the damping fluid.

[0072] Furthermore, for ease of description, the springs located on the upper and lower sides of the piston 804 can be referred to as the upper spring 805 and the lower spring 806, respectively. Both springs are in a pre-tightened state in the housing, and by applying force to the piston 804, they can keep the piston 804 approximately in the middle position in the height direction of the housing cavity when the vehicle is not vibrating.

[0073] In this embodiment, to prevent the damping fluid from flowing through the gap between the piston 804 and the inner wall of the housing, preferably, for example, a rubber sleeve 8042 can be provided on the outer peripheral wall of the piston 804, so that the piston 804 slides in contact with the inner wall of the housing through the rubber sleeve 8042. Furthermore, in practice, the aforementioned damping holes 8041 can generally be configured as multiple holes spaced apart on the piston 804, and the multiple damping holes 8041 can be arranged circumferentially along the piston 804.

[0074] In this embodiment, given that one end of the upper connecting post 803 extends out of the housing and also needs to move relative to the housing, in order to avoid leakage of damping fluid at the upper connecting post 803, a sealing ring 808 can be provided between the housing 801 and the upper connecting post 803, and the sealing ring 808 can usually be set as a plurality of rings spaced apart along the axial direction of the upper connecting post 803 to ensure the sealing effect.

[0075] During assembly of the aforementioned mounting assembly 8, first, the upper spring is fitted onto the upper connecting post 803. After embedding the sealing ring 808 into the groove on the housing 801, the upper connecting post with the piston 804 can be installed into the housing 801. Next, the lower spring 806 is installed, and then the end cap 802 is placed on top and fixed to the housing 801. Finally, damping fluid (e.g., hydraulic oil) is injected through the filling hole on the end cap 802. After filling, the filling hole is sealed with the plug 809.

[0076] In use, that is, when installing the power supply box 100 of this embodiment in a vehicle, based on the mounting holes 7 on the power supply box 100, a smaller diameter connecting end 8031 ​​provided at the top of the upper connecting post 803 can be used to connect to the power supply box 100. Both the connecting end 8031 ​​and the lower connecting post 807 located at the bottom can be externally threaded posts. Thus, by using nuts that mate with the connecting end 8031 ​​and the lower connecting post 807 respectively, the power supply box 100 can be installed in the vehicle via the mounting assembly 8.

[0077] When the vehicle vibrates due to road conditions, the vibration is transmitted to the mounting component 8. At this time, the power supply box 100 causes the piston 804 to move up and down in the housing, and the vibration is buffered and absorbed by the springs on the upper and lower sides. At the same time, the damping fluid in the chambers on both sides of the piston 804 flows through the damping holes 8041 designed on the piston 804, which can also play a good damping role during the up and down movement of the piston 804. This makes the power supply box 100 vibrate more smoothly with the vehicle, thus achieving an effective vibration reduction effect.

[0078] The power supply device for the sensor equipment used in the autonomous vehicle testing of this embodiment adopts the above design. Not only can the relay K1 contact only connect the first electrical connection port 1 and the control switch 4 when the second electrical connection port 2 is connected to the power supply of KL15, so as to avoid energy waste and damage to the battery caused by the sensor equipment working continuously when the vehicle is in sleep mode, but also the setting of multiple third electrical connection ports 3 can avoid the occurrence of misoperation. It not only overcomes the shortcomings of the prior art, but also has good practicality and is conducive to use in the testing of autonomous vehicles.

[0079] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
