Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicles and T-BOX, and specifically to a device and method for switching a T-BOX power supply in an emergency, and a new energy vehicle. Background Art

[0002] New energy vehicles (NEVs) are vehicles that utilize unconventional automotive fuels as a power source (or conventional fuels with new onboard power units), integrating advanced technologies in vehicle power control and drive, resulting in advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. New energy vehicles can be categorized broadly and narrowly based on their scope. Broadly defined, new energy vehicles, also known as alternative fuel vehicles, include vehicles that entirely use non-petroleum fuels, such as pure electric vehicles and fuel cell electric vehicles, as well as vehicles that partially use non-petroleum fuels, such as hybrid electric vehicles and ethanol gasoline vehicles. This concept encompasses all existing new energy vehicles, which are specifically divided into six categories: hybrid vehicles, pure electric vehicles, fuel cell vehicles, alcohol-ether fuel vehicles, and natural gas vehicles. For a narrower definition of new energy vehicles, please refer to the national "Administrative Rules for the Access of New Energy Vehicle Manufacturers and Products": New energy vehicles are vehicles that utilize unconventional automotive fuels as a power source, integrating advanced technologies in vehicle power control and drive, resulting in advanced technologies, new structures, and advanced technical principles.

[0003] Currently, most new energy vehicles are equipped with an onboard T-Box. The T-Box (Telematics Box) is the core controller for vehicle informationization, collecting vehicle bus signals in real time. Connecting to the TSP backend via 4G / 5G enables functions such as uploading vehicle status, reporting vehicle faults, remote diagnosis, vehicle alarms, and remote control. Users can remotely control their vehicles and diagnose their health status via a mobile app. The T-Box is a crucial component in the Internet of Vehicles (IoT). An IoV system generally consists of a host computer, an onboard T-Box, a mobile app, and a backend system. T-Box, short for Telematic Box, generally refers to the intelligent in-vehicle terminal in an IoV system. Simply put, the T-Box is one of the primary methods for data collection. It acquires vehicle data and uploads it to the TSP backend, or receives commands from the backend and returns execution results. The vehicle owner can then remotely control the vehicle using a smart key or mobile app. Primarily targeting the IoT market, the T-Box allows for remote monitoring and operation of equipment or vehicles. As a wireless gateway, the T-Box provides a remote communication interface for the entire vehicle and offers a variety of functions. However, to date, it primarily provides the following three types of services: Vehicle information acquisition, such as vehicle fault monitoring, driving behavior analysis, driving data collection, tire pressure status, and door status. Remote vehicle control, such as air conditioning control, window control, engine start / stop, and door unlocking. Security services, such as remote alarm and location tracking after vehicle theft, one-click rescue, and vehicle towing alarm.

[0004] Existing T-BOXs (and in-vehicle gateways) are equipped with various emergency detection modules, such as a rollover module (for detecting vehicle rollovers); a fire module (for detecting battery fires); and a collision module (for detecting vehicle collisions and also connecting to the airbag module to obtain airbag deployment signals). Typically, the T-BOX is connected to the vehicle's main battery via wires. However, in the event of an emergency such as a rollover, fire, or collision, the main battery is likely to be damaged and unable to continue powering the T-BOX. To ensure that the T-BOX can continue to operate normally in the event of such emergencies, the T-BOX must be replaced and connected to a power source without shutting down.

[0005] However, existing T-BOXs cannot automatically change power connections without shutting down the vehicle. Furthermore, disassembling a T-BOX in a new energy vehicle requires disassembling the vehicle's housing, making the process relatively complex. To address this, we propose a device and method for switching the T-BOX power supply in an emergency, as well as a new energy vehicle. Summary of the Invention

[0006] In order to make up for the shortcomings of the above-mentioned existing T-BOX that cannot automatically replace the power connection without shutting down, and the relatively complicated T-BOX disassembly process in current new energy vehicles, the present application provides a T-BOX power switching device, method and new energy vehicle in an emergency.

[0007] The technical solution of this application is:

[0009] As an optimal technical solution, the elastic driving source is composed of two thrust springs 1, and the parallel elastic double contacts also include an inner hole guide frame and several guide rods 2.

One side of several static contacts for spare batteries is installed with an insulating fixed support plate 2, and one side of several cylindrical static contacts for vehicle batteries is installed with an insulating fixed support plate 1.

[0010] As a preferred technical solution, several guide rods 1 are installed between the insulating fixed support plate 1 and the insulating fixed support plate 2, and the guide rod 1 passes through the inner hole guide frame. The power source 1 includes a 90-degree servo, a rotating rod and a chain. The 90-degree servo, the insulating fixed support plate 1 and the insulating fixed support plate 2 are all installed on the T-BOX bottom plate.

Two spare batteries are connected to one side of the static contact of several spare batteries.

[0011] On the other hand, the present application also provides a method for switching the T-BOX power supply in an emergency, including the T-BOX power supply switching device in an emergency. When an emergency occurs such as a rollover, fire, or collision, the specific steps of the T-BOX power supply switching method are as follows:

[0012] Step 1: Signal collection: Specifically, the rollover module, fire module, or collision module in the T-BOX detects an emergency situation such as a rollover, fire, or collision of the vehicle;

[0013] Step 2: transmit signal and switch power supply; specifically, the detected signal is transmitted to the ninety-degree servo through T-BOX, and the ninety-degree servo that receives the signal drives the rotating rod and chain to rotate within a preset angle through the output shaft, pulling the inner hole guide frame in the parallel elastic double contacts to move left along the guide rod, driving the thrust spring one whose right end is compressed by the cylindrical vehicle battery static contact and the right end of the linear moving contact to gradually stretch out, until the width between the two groups of the linear moving contacts is the same as the distance between several cylindrical vehicle battery static contacts and several backup battery static contacts, all the left The linear moving contact and the plurality of cylindrical backup battery static contacts are in contact and connected with each other. That is, at this time, the two groups of linear moving contacts are connected in parallel to the vehicle battery and the backup battery through the plurality of cylindrical vehicle battery static contacts and the plurality of backup battery static contacts, respectively. Then, as the 90-degree servo output shaft continues to rotate, the thrust spring 1 at the left end is gradually compressed, and the linear moving contact at the right end is gradually moved away from the plurality of cylindrical vehicle battery static contacts. This ensures that the T-BOX is always powered on, that is, the T-BOX power supply is switched without being shut down.

[0017] As an optimal technical solution, the static contact for the backup battery includes a Y-shaped static contact, and the Y-shaped static contact includes a cylindrical backup battery static contact and two linear static contacts.

A plurality of Y-shaped static contacts are respectively installed in the plurality of Y-shaped through-holes. A connecting rod is installed on the upper end of the insulating rod, and two battery boxes are installed at the end of the connecting rod. The two spare batteries are respectively installed in the two battery boxes. A thrust spring 2 is installed in the battery box, and the thrust spring 2 and the spare battery are in mutual extrusion contact. Relative arc-shaped slots are provided on the upper and lower inner walls of the inlet end of the battery box. The two spare batteries are respectively connected to the two groups of cylindrical moving contacts through wires, plugs and sockets. An insulating fixed connecting plate is installed on one side of the two groups of cylindrical moving contacts, and the two insulating fixed connecting plates are respectively installed at the ends of the two battery boxes.

[0019] As a preferred technical solution, a box cover is installed at the inlet end of the battery box, a switch knob is installed on the box cover, the box cover is provided with a rotating hole, the switch knob includes a turning knob, a rotating shaft and an elliptical plate, the rotating shaft is installed in the rotating hole, the turning knob and the elliptical plate are respectively installed at the two ends of the rotating shaft, the elliptical plate is installed on the inner side of the box cover, the ends of the two battery boxes are connected with arc-shaped baffles, a switching rod is installed on the arc-shaped baffle, and an automatic locking part is installed between the T-BOX bottom plate and the switching rod.

[0020] As an optimal technical solution, the automatic locking part includes two circular hole-shaped slots and a self-locking part. The two circular hole-shaped slots are respectively arranged on the T-BOX bottom plate. The self-locking part includes an anti-touch rod, a check rod, a plurality of thrust springs and a plurality of telescopic rods. The anti-touch rod is installed below the switching rod, the upper ends of a plurality of telescopic rods are installed in the switching rod, the lower ends of a plurality of telescopic rods are installed on the anti-touch rod, a plurality of thrust springs are installed between the anti-touch rod and the switching rod, the check rod is installed at the end of the anti-touch rod, and the check rod is arranged in one of the circular hole-shaped slots.

[0021] As a preferred technical solution, the T-BOX shell is installed on the T-BOX bottom plate, the in-vehicle suspension is provided with a limit positioning groove, and the lower end of the T-BOX bottom plate is installed in the limit positioning groove. The shell clamping device includes two inner hole fixing blocks, a rectangular frame clamping arm, two rubber sleeves, two tension springs and a cylindrical handle.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] First, the present application realizes that the T-BOX is always in a powered state through an uninterruptible power supply switching component, that is, the T-BOX power supply switching is completed without shutting down the T-BOX. Specifically, the T-BOX transmits the detected signal to the ninety-degree servo. The ninety-degree servo that receives the signal drives the rotating rod and the chain to rotate left within a preset angle through the output shaft, pulling the inner hole guide frame in the parallel elastic double contact to move left along the guide rod, driving the thrust spring whose right end is compressed by the cylindrical vehicle battery static contact and the right end linear moving contact to gradually stretch until the width between the two sets of linear moving contacts is equal to the distance between several cylindrical vehicle battery static contacts and several spare battery static contacts. At the same time, the linear moving contact on the left and the several cylindrical backup battery static contacts come into contact and connect with each other. That is, the two sets of linear moving contacts are now connected in parallel through the several cylindrical vehicle battery static contacts and the several backup battery static contacts, respectively, so that the vehicle battery and the backup battery are connected in parallel. This ensures that the T-BOX is always connected to the power supply when switching power, and the power will not be cut off. Then, as the 90-degree steering gear output shaft continues to rotate, the thrust spring on the left end is gradually compressed, and the linear moving contact on the right end gradually moves away from the several cylindrical vehicle battery static contacts. This ensures that the T-BOX is always powered on, that is, the T-BOX power supply is switched without being shut down.

[0024] Secondly, the present application uses a dual backup battery switching connection portion to troubleshoot a backup battery fault in the T-BOX while removing the T-BOX, thereby eliminating the need to disassemble the T-BOX. Specifically, the switching lever and the anti-touch lever are manually held simultaneously to drive the check rod on the anti-touch lever upward and away from the circular hole-shaped slot, and the switching lever is pushed to rotate with the arc-shaped baffle and the two battery boxes, so that the other set of the two sets of cylindrical moving contacts is in contact with a number of Y-shaped static contacts. The switching lever and the anti-touch lever are then released, and the compressed thrust spring pushes the anti-touch rod downward, driving the check rod to fall into the other circular hole-shaped slot, limiting the rotation of the switching lever. The user then observes whether the car continues to remind the T-BOX of a fault. If the car does not continue to remind the T-BOX of a fault, it means that the T-BOX is faulty because of the previously connected backup battery, eliminating the need to disassemble the T-BOX. At this time, the outer cover of the faulty backup battery only needs to be opened for replacement.

[0025] Third, the present application installs the T-BOX on the suspension inside the car below the driver's seat. This position is not only covered and protected by the original carpet in the car, but also the original carpet part under the driver's seat can be lifted up, which is convenient for the later maintenance of the T-BOX. Then, with the help of the shell clamping device, the T-BOX can be quickly removed without disassembling the shell inside the car. After lifting the original carpet part under the driver's seat of the car to expose the T-BOX, you only need to manually hold the cylindrical handle and lift up the rectangular frame clamping arm to remove the T-BOX.

[0040] See also Figure 1-9 , this application describes the above technical solution in detail through the following embodiments:

[0041] A T-BOX power switching device for emergency situations includes a T-BOX baseplate 1, several cylindrical vehicle-mounted battery static contacts 206 arranged equidistantly in a straight line, and several backup battery static contacts arranged equidistantly in a straight line. The cylindrical vehicle-mounted battery static contacts 206 are interconnected with the vehicle's onboard battery via wires. When the vehicle is in normal driving, the T-BOX is powered by the vehicle's onboard battery. An uninterruptible power supply switching element 2 is mounted on the T-BOX baseplate 1. The uninterruptible power supply switching element 2 includes parallel elastic dual contacts. The parallel elastic dual contacts are reciprocally driven by a power source and can reciprocally contact and connect the cylindrical vehicle-mounted battery static contacts 206 or the backup battery static contacts.

[0042] In this embodiment, the parallel elastic double contacts include two groups of linear moving contacts 207 connected in parallel with each other. The linear moving contacts 207 in each group are arranged in a straight line with equal distances. The two groups of linear moving contacts 207 are connected to the main circuit in the T-BOX through wires. The two groups of linear moving contacts 207 are connected in parallel with each other through wires. They are mainly used to enable the T-BOX to be powered by the vehicle battery and the backup battery 316 at the same time. The two groups of linear moving contacts 207 are directly opposite to the cylindrical vehicle battery static contacts 206 and the backup battery static contacts. The two groups of linear moving contacts 207 are pushed by the elastic force of the elastic driving source and can move away from each other, respectively approaching a number of cylindrical vehicle battery static contacts 206 and a number of spare battery static contacts, and when the above-mentioned elastic driving source is not under pressure, the width between the two groups of linear moving contacts 207 is greater than the distance between the number of cylindrical vehicle battery static contacts 206 and the number of spare battery static contacts, which is used to ensure that the two groups of linear moving contacts 207 are always connected to a number of cylindrical vehicle battery static contacts 206 or a number of spare battery static contacts.

[0043] In this embodiment, the elastic driving source is composed of two thrust springs 1 210, and the thrust springs 1 210 are always in a compressed state. The parallel elastic double contacts also include an inner hole guide frame 209 and a plurality of guide rods 211. The inner hole guide frame 209 is horizontally movably installed on the T-BOX bottom plate 1. The two thrust springs 1 210 are respectively fixedly installed on both sides of the inner hole guide frame 209. The plurality of guide rods 211 are respectively fixedly installed on both sides of the inner hole guide frame 209. The ends of the plurality of guide rods 211 are fixedly installed with limited discs 212. The two groups of linear moving contacts 207 are respectively slidably connected to the plurality of guide rods 211, that is, the two groups of linear moving contacts 207 can Moving along several guide rods 211, one side of the cylindrical spare battery static contact 3011 among the several spare battery static contacts is fixedly installed with an insulating fixed support plate 205, and two limiting discs 212 are used to limit the distance that the linear moving contact 207 moves to the left or right, respectively. One side of several cylindrical vehicle battery static contacts 206 is fixedly installed with an insulating fixed support plate 1 204, and the insulating fixed support plate 1 204 and the insulating fixed support plate 2 205 are parallel to each other. The insulating fixed support plate 1 204 and the insulating fixed support plate 2 205 are mainly used to support and install several cylindrical vehicle battery static contacts 206 and several cylindrical spare battery static contacts 3011.

[0044] In this embodiment, a plurality of guide rods 1 208 are fixedly installed between the insulating fixed support plate 1 204 and the insulating fixed support plate 2 205. The guide rod 1 208 slides through the inner hole guide frame 209, that is, the inner hole guide frame 209 can move left and right along the guide rod 1 208. The power source 1 includes a ninety-degree steering gear 201, a rotating rod 202 and a chain 203. The ninety-degree steering gear 201, the insulating fixed support plate 1 204 and the insulating fixed support plate 2 205 are all fixedly installed on the T-BOX bottom plate 1. The output shaft of the ninety-degree steering gear 201 is connected to the rotating rod 202 through a coupling. 02 is fixedly connected at its head end, the end of the rotating rod 202 is fixedly connected or movably connected to one end of the chain 203, the end of the chain 203 is fixedly installed or movably connected to the inner hole guide frame 209, and several backup batteries are connected to two backup batteries 316 on one side of the static contact. At present, only one backup battery 316 is installed in the existing T-BOX, but most T-BOXs prompt that the T-BOX has failed because the backup battery 316 has bulged and damaged. Therefore, the present invention adopts two backup batteries 316, which can be switched for use.

[0045] A method for switching T-BOX power in an emergency, including the above-mentioned T-BOX power switching device in an emergency, is provided. When an emergency occurs such as a rollover, fire, or collision, the specific steps of the T-BOX power switching method are as follows:

[0046] Step 1: Signal collection: Specifically, the rollover module, fire module, or collision module in the T-BOX detects an emergency situation such as a rollover, fire, or collision of the vehicle;

[0047] Step 2: Transmit signal and switch power supply; specifically, the detected signal is transmitted to the ninety-degree servo 201 through the T-BOX. The ninety-degree servo 201 that receives the signal drives the rotating rod 202 and the chain 203 to rotate to the left within a preset angle through the output shaft, and pulls the inner hole guide frame 209 in the parallel elastic double contact to move to the left along the guide rod 1 208, driving the thrust spring 1 210 whose right end is compressed by the cylindrical vehicle battery static contact 206 and the right end linear moving contact 207 to gradually stretch out, until the width between the two groups of linear moving contacts 207 is the same as the distance between several cylindrical vehicle battery static contacts 206 and several spare battery static contacts, the linear moving contact 207 on the left and several cylindrical vehicle battery static contacts 206 are connected. The cylindrical backup battery static contacts 3011 are in contact and connected. This means that the two sets of linear moving contacts 207 are connected in parallel to the vehicle battery and the backup battery 316 via the cylindrical vehicle battery static contacts 206 and the backup battery static contacts, respectively. This ensures that the T-BOX remains connected to the power source during power switching, preventing power outages. As the output shaft of the 90-degree servo 201 continues to rotate, the thrust spring 1 210 on the left side is gradually compressed, gradually moving the linear moving contact 207 on the right side away from the cylindrical vehicle battery static contacts 206. This ensures that the T-BOX remains energized, allowing the T-BOX to switch power without shutting down.

[0048] The new energy vehicle includes the above-mentioned T-BOX power switching device in an emergency, the above-mentioned T-BOX power switching method in an emergency, an in-vehicle suspension 11 and a T-BOX shell 13.

The shell clamping device mainly uses the elastic force of the two tension springs 8 to pull the T-BOX bottom plate 1 in the T-BOX and stably install it in the limit positioning groove 12.

[0049] In this embodiment, a dual backup battery switching connection part 3 is installed in the T-BOX shell 13. The dual backup battery switching connection part 3 includes two groups of cylindrical moving contacts 311.

Then, the switch lever 306 and the anti-touch lever 307 are manually held at the same time, driving the check rod 308 on the anti-touch lever 307 upward away from the circular hole-shaped slot 4, and pushing the switch lever 306 to rotate with the arc-shaped baffle 305 and the two battery boxes 304, so that the other set of the two sets of cylindrical moving contacts 311 is in contact with the plurality of Y-shaped static contacts 301. Then, the switch lever 306 and the anti-touch lever 307 are released, and the compressed thrust spring 33 is released. 20 pushes the anti-touch rod 307 downward, driving the check rod 308 to fall into another circular hole-shaped slot 4, limiting the rotation of the switch rod 306, and observes whether the car continues to remind the T-BOX of the fault. If it does not continue to remind the T-BOX of the fault, it means that the T-BOX is faulty because of the previously connected backup battery 316, eliminating the need to disassemble the T-BOX. At this time, only the outer cover 309 of the faulty backup battery 316 needs to be opened and replaced. That is, when the knob 310 is turned and the oval plate 319 is completely separated from the two arc-shaped slots 314, the oval plate 319 is 9 can no longer restrict the box cover 309 from being pulled out along the inlet end of the battery box 304. When the box cover 309 is pulled out from the battery box 304, the thrust spring 2 315 uses its own elastic force to push one end of the spare battery 316 that is in contact with it out of the inlet end of the battery box 304, making it easier for manual replacement. After the spare battery 316 is replaced, the box cover 309 is re-covered on the inlet end of the battery box 304, and the knob 310 is rotated to drive the internal elliptical plate 319 to rotate through the shaft 318. When the two ends of the elliptical plate 319 are stuck in the two arc-shaped slots 314, the switch knob restricts the box cover 309 from being pulled out. When the box cover 309 is covered on the battery box 304, the second thrust spring 315 pushes the spare battery 316 and the box cover 309 to squeeze each other through its own elastic force, and is stably installed in the battery box 304; if the switching lever 306 is rotated to switch the spare batteries 316 connected to several Y-shaped static contacts 301, the car will continue to remind that the T-BOX has a fault. Only by manually holding the cylindrical handle 10 and lifting the rectangular frame clamping arm 6 can the T-BOX be disassembled and removed, without the need to disassemble the shell inside the car, thereby simplifying the process of disassembling and repairing the T-BOX.
