Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but is intended to be accorded the broadest scope consistent with the claims.

[0030] The terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. For example, as used herein, the singular forms "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. When used in this specification, the terms "comprise," "include," and / or "contain" are intended to refer to the presence of the associated features, integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups or the addition of other features, integers, steps, operations, elements, components, and / or groups in the system / method.

[0031] These and other features of this specification, as well as the operation and function of the associated elements of the structure, and the economical assembly and manufacture of the components, can be significantly improved with consideration of the following description. Reference is made to the accompanying drawings, all of which form a part of this specification. However, it should be expressly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0032] The flowcharts used in this specification illustrate operations implemented by systems according to some embodiments of the present specification. It should be clearly understood that the operations of the flowcharts may not be implemented in sequence. Rather, the operations may be implemented in reverse order or simultaneously. Furthermore, one or more additional operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

[0033] In this specification, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. In other words, X may include only any one of A, B, and C, or any combination of A, B, and C, as well as other possible contents / elements.

And so on.

[0035] With the advancement of technology, a wide variety of vehicles have appeared in people's lives, bringing great convenience to people's lives. Vehicles may include brake assemblies, which allow users to control the vehicle's brakes. However, there is a risk of damage to the brake assembly, which can cause the brake function to fail. With existing vehicles, when the brake assembly is damaged, it is difficult for the user to detect it in a timely manner, increasing the probability of driving accidents. Therefore, there is a need to provide a vehicle that can facilitate the user to promptly detect damage to the brake assembly when it is damaged.

[0036] In view of this, an embodiment of the present specification provides a vehicle that can detect the failure of the transmission mechanism through a detection component when the transmission mechanism fails, so that the failure of the transmission mechanism can be discovered in time, making it easier for the user or the vehicle to take active countermeasures.

[0037] Below, the technical solutions of the embodiments of this specification will be described in detail with reference to the accompanying drawings.

[0038] Vehicles may include long-distance vehicles and short-distance transportation vehicles. In this specification, long-distance vehicles include automobiles. Short-distance transportation vehicles refer to various devices and tools used to meet an individual's transportation needs over relatively short distances, such as scooters and self-balancing vehicles. These devices are typically portable, easy to operate, and environmentally friendly, making them suitable for short-distance travel within a city or a specific area. They can effectively replace or supplement traditional transportation, reducing traffic congestion and environmental pollution.

[0039] This specification uses a scooter as an example to illustrate the above-mentioned vehicle. However, those skilled in the art will appreciate that other types of short-distance vehicles are also applicable to the invention described in this specification without departing from its spirit.

[0040] The scooter provided herein can be a short-distance transportation scooter. It can be ridden standing up and is compact and lightweight, making it suitable for navigating confined spaces and offering significant advantages for ultra-short-distance travel. In particular, the scooter is relatively small in its width direction. The width direction of the scooter can be the axial direction of the scooter's wheels. This results in a relatively small size and light weight, making it ideal for short-distance travel. Scooters can include three-wheeled scooters, two-wheeled scooters, and the like.

[0041] Figure 1 FIG2 shows a schematic diagram of a three-dimensional structure of a vehicle provided according to some embodiments of the present application. Figure 1 As shown, vehicle 001 may include a main body 100. Main body 100 is the main structure of vehicle 001, used to perform the functions of driving and carrying passengers of vehicle 001. Main body 100 may include a body 150, at least one wheel 111, 112 and a suspension system 180.

[0042] The body 150 can be the base of the main body 100. The body 150 can be used to connect various components of the vehicle 001, such as wheels, suspension system 180, etc. The body 150 can also be used to carry users. The body 150 can have a variety of different structures to adapt to different application scenarios. For example, the vehicle 001 is a balance car, a tricycle or a scooter, wherein the body 150 of the balance car, tricycle and scooter can have different structures. Figure 1The following description uses a three-wheeled scooter as an example. Those skilled in the art will appreciate that other structures of the body 150 are also within the scope of protection of this specification. The body 150 can be made of metal, such as carbon steel, aluminum alloy, titanium alloy, etc. It can also be made of carbon fiber. The body 150 can also be a combination of various materials, and this specification does not limit this.

[0043] The vehicle body 150 may also include a carrying portion 156 for carrying a user. Figure 1 The support portion 156 of the vehicle body 150 shown can be used to support the user's feet. The user can stand on the vehicle body 150 to drive the vehicle 001. In some embodiments, the vehicle body 150 may also include a seat, so that the user can sit on the seat to drive the vehicle 001. In some embodiments, the vehicle body 150 may also include a storage area for storing items. In some embodiments, the vehicle body 150 may also include other components, which are not limited in this specification.

[0044] At least one wheel can be the driving component of vehicle 001. Each of the at least one wheel can be rotatably connected to vehicle body 150 to enable vehicle 001 to travel. The tires of the wheels can be pneumatic tires or solid rubber tires, which are not limited in this specification. The wheels can have a metal frame inside to support the tires.

[0045] Furthermore, the main body 100 may include a drive motor disposed on the vehicle body. At least one wheel includes a drive wheel, which is driven by the drive motor to rotate, thereby driving the vehicle 001 to travel.

[0046] In some embodiments, as Figure 1 As shown, the at least one wheel may include a first wheel 1111 and a second wheel 1112, such as in a self-balancing vehicle. The first wheel 1111 and the second wheel 1112 may be located on either side of the vehicle body 150, so that the vehicle body 150 can stand without a kickstand. Furthermore, the first wheel 1111 and the second wheel 1112 may be symmetrically distributed on either side of the vehicle body 150.

[0047] In some embodiments, the vehicle 001 may further include other wheels, which are distributed along the longitudinal direction of the vehicle body 150 together with the first wheel 1111 and the second wheel 1112 . The longitudinal direction may be the driving direction of the vehicle body 150 .

[0048] In some embodiments, as Figure 1As shown, the at least one wheel may include a front wheel 111 and a rear wheel 112. The front wheel 111 and the rear wheel 112 may be arranged along the longitudinal direction of the vehicle body 150. The longitudinal direction may be the direction of travel of the vehicle body 150. At least one of the front wheel 111 and the rear wheel 112 may be driven to rotate relative to the vehicle body 150, thereby driving the scooter. The front wheel 111 and the rear wheel 112 may be respectively connected to the vehicle body 150 to drive the vehicle body 150. In some embodiments, the first wheel 1111 and the second wheel 1112 may be the front wheels 111 of the vehicle 001. In this case, the number of rear wheels 112 may be one or two, and they may be symmetrically distributed on both sides of the vehicle body 150. In other embodiments, the first wheel 1111 and the second wheel 1112 may be the rear wheels 112 of the vehicle 001. In this case, the number of front wheels 111 may be one or two, and they may be symmetrically distributed on both sides of the vehicle body 150. For ease of description, this application describes the first wheel 1111 and the second wheel 1112 as the front wheels 111 of the vehicle 001. Of course, those skilled in the art will appreciate that the first wheel 1111 and the second wheel 1112 as the rear wheels 112 of the vehicle 001 are also within the scope of protection of this specification.

[0049] In some embodiments, as Figure 1 As shown, the main body 100 includes a steering column 151 and a handlebar 152. The handlebar 152 is fixedly connected to the steering column 151, and the body 150 is rotatably connected to the steering column 151. The front wheel 111 is rotatably connected to the steering column 151, and is further rotatably connected to the body 150 via the steering column 151. Furthermore, the body 150 is pivotally connected to the steering column 151.

[0050] One end of the handlebar 152 includes a handle grip 153. In some embodiments, each end of the handlebar 152 may include a handle grip 153. The grips 153 can be held by the user. When the vehicle 001 needs to turn, the user can use the grips 153 to rotate the handlebar 152 relative to the vehicle body 150, thereby rotating the steering tube 151 and the front wheel 111 relative to the vehicle body 150, thereby enabling the user to steer the vehicle 001.

[0051] In some embodiments, as Figure 1As shown, the main body 100 includes a bow tube 155, which is fixed to the vehicle body 150. The steering tube 151 is rotatably connected to the bow tube 155, and the steering tube 151 is rotatably connected to the vehicle body 150. The front wheel 111 can be rotatably connected to the vehicle body 150 through the steering tube 151 and the bow tube 155.

[0052] In other embodiments, the handlebar 152 of the main body 100 may also be replaced with a steering wheel.

[0053] like Figure 1 As shown, suspension system 180 can be used to connect at least one wheel of vehicle 001 to body 150. In other words, at least one wheel can be connected to body 150 via suspension system 180. Suspension system 180 is a general term for all force-transmitting connections between body 150 and wheels. Its function is to transmit forces and torque acting between body 150 and the wheels. Suspension system 180 can also cushion impact forces transmitted to body 150 by uneven roads and reduce the resulting vibrations, ensuring smooth travel for vehicle 001.

[0054] Figure 2 A schematic diagram of a partial front view structure of a vehicle provided according to some embodiments of the present application is shown. Figure 3 FIG. 1 shows another schematic diagram of a partial front view of a vehicle according to some embodiments of the present application. Figures 1 to 3 As shown, the vehicle 001 further includes a brake assembly 200. The brake assembly 200 is disposed on the body 100 and includes at least a brake mechanism 210, a transmission mechanism 230, and a brake lever 250.

[0055] Braking mechanism 210 is configured to restrict the rotation of at least one wheel. Braking mechanism 210 can be located at the hub of at least one wheel and restrict the rotation of at least one wheel by generating friction. For example, braking mechanism 210 includes a disc brake structure or a drum brake structure.

[0056] Braking mechanism 210 may include at least one sub-braking mechanism. The number of the at least one sub-braking mechanism may correspond to the number of wheels. For example, the number of sub-braking mechanisms and the number of wheels may both be two or three. Furthermore, each sub-braking mechanism includes a disc brake structure or a drum brake structure to limit the rotation of the corresponding wheel.

[0057] In some embodiments, as Figure 2 and Figure 3 As shown, the at least one sub-brake mechanism includes a first sub-brake mechanism 211 and a second sub-brake mechanism 212 . The first sub-brake mechanism 211 is configured to limit the rotation of the first wheel 1111 , and the second sub-brake mechanism 212 is configured to limit the rotation of the second wheel 1112 .

[0058] Furthermore, at least one of the sub-brake mechanisms includes a third sub-brake mechanism 210; at least one wheel includes a third wheel, and the third sub-brake mechanism 210 is configured to limit the rotation of the third wheel. Figure 1 As shown, the first wheel 1111 and the second wheel 1112 are front wheels 111, and the third wheel is a rear wheel 112. In other embodiments, the first wheel 1111 and the second wheel 1112 are rear wheels 112, and the third wheel is a front wheel 111.

[0059] like Figure 2 and Figure 3 As shown, a brake lever 250 is connected to the brake mechanism 210 via a transmission mechanism 230, so that the transmission mechanism 230 drives the brake mechanism 210 to move, thereby limiting the rotation of the at least one wheel. When a user manually presses the brake lever 250, the brake lever 250 drives the brake mechanism 210 via the transmission mechanism 230, thereby controlling the vehicle 001 to slow down and stop.

[0060] In some embodiments, the vehicle 100 can be braked via a brake cable 231. Accordingly, the transmission mechanism 230 includes a brake cable 231. When a user manually presses a brake lever 250, the brake lever 250 drives the brake mechanism 210 via the brake cable 231, thereby controlling the vehicle 100 to decelerate and stop.

[0061] The number of brake lines 231 can be one or more. For example, in some embodiments, there is one brake line 231. One brake line 231 is connected to one sub-brake mechanism, which is used to limit the rotation of one wheel. For another example, in other embodiments, there is one brake line 231. One brake line 231 is connected to two sub-brake mechanisms, which are used to limit the rotation of two wheels. For another example, in other embodiments, there are two brake lines 231. One of the brake lines 231 is connected to one sub-brake mechanism, which is used to limit the rotation of one wheel. The other brake line 231 is connected to two sub-brake mechanisms, which are used to limit the rotation of two wheels.

[0062] In some embodiments, as Figure 2 and Figure 3As shown, at least one of the brake lines 231 includes a main brake line 232, a first sub-brake line 2321, and a second sub-brake line 2322. The main brake line 232 is transmission-connected to the first sub-brake mechanism 211 via the first sub-brake line 2321, and is transmission-connected to the second sub-brake mechanism 212 via the second sub-brake line 2322. The main brake line 232 can also be connected to the brake handle 250. When the user manually presses the brake handle 250, the brake handle 250 can drive the main brake line 232 to move. Driven by the brake handle 250, the main brake line 232 can trigger the first sub-brake mechanism 211 and the second sub-brake mechanism 212 to operate via the first sub-brake line 2321 and the second sub-brake line 2322, thereby respectively limiting the rotation of the first wheel 1111 and the second wheel 1112.

[0063] In this way, the user can achieve synchronous braking of the two front wheels 1111, 1112 by pressing the brake handle 250 with one hand. The synchronous braking of the first wheel 1111 and the second wheel 1112 is beneficial to improving the driving stability of the vehicle 001 during the braking process.

[0064] In some embodiments, the brake assembly 200 may include two left and right brake levers 250. Each of the left and right brake levers 250 may be connected to a brake cable 231 to brake the two front wheels 1111 and 1112 and the rear wheel 112, respectively. By splitting the brake cable 231, simultaneous braking of more than two wheels can be achieved.

[0065] In some embodiments, the brake line 231 includes a mechanical splitter 234 , and the main brake line 232 is connected to the first sub-brake line 2321 and the second sub-brake line 2322 through the mechanical splitter 234 .

[0066] In addition to braking by brake lines, the vehicle 100 can also be braked by hydraulic pressure. Accordingly, in some embodiments, the transmission mechanism 230 includes a hydraulic pipe 241. When the user manually presses the brake handle 250, the braking power can be transmitted from the brake handle 250 to the braking mechanism 210 by hydraulic transmission. For example, the hydraulic pipe 241 contains flowable brake oil to transmit the braking power. Accordingly, the hydraulic pipe 241 is an oil pipe. In the vehicle 001, the deployment of the hydraulic pipe 241 can refer to Figure 2 、 Figure 3 and Figure 5 Deployment of the middle brake line 231.

[0067] The number of hydraulic pipes 241 can be one or more. For example, in some embodiments, there is one hydraulic pipe 241. One hydraulic pipe 241 is connected to one sub-brake mechanism, which is used to limit the rotation of one wheel. For another example, in other embodiments, there is one hydraulic pipe 241. One hydraulic pipe 241 is connected to two sub-brake mechanisms, which are used to limit the rotation of two wheels. For another example, in other embodiments, there are two hydraulic pipes 241. One of the hydraulic pipes 241 is connected to one sub-brake mechanism, which is used to limit the rotation of one wheel. The other hydraulic pipe 241 is connected to two sub-brake mechanisms, which are used to limit the rotation of two wheels.

[0068] In some embodiments, at least one of the hydraulic pipes 241 includes a main pipe, a first sub-pipe, and a second sub-pipe. The main pipe is transmission-connected to the first sub-brake mechanism 211 via the first sub-pipe, and the main pipe is transmission-connected to the second sub-brake mechanism 212 via the second sub-pipe. The main pipe can also be connected to the brake handle 250. When the user manually presses the brake handle 250, the brake handle 250 can drive the hydraulic fluid in the main pipe to move. Driven by the brake handle 250, the hydraulic fluid in the main pipe can trigger the first sub-brake mechanism 211 and the second sub-brake mechanism 212 to operate via the hydraulic fluid in the first sub-hydraulic pipe 241 and the hydraulic fluid in the second sub-hydraulic pipe 241, thereby respectively limiting the rotation of the first wheel 1111 and the second wheel 1112.

[0069] In this way, the user can achieve synchronous braking of the two front wheels 1111 and 1112 by pressing the brake handle 250 with one hand. The synchronous braking of the first wheel 1111 and the second wheel 1112 is beneficial to improving the driving stability of the vehicle 001 during the braking process.

[0070] In some embodiments, the brake assembly 200 may include left and right brake levers 250. Each of the left and right brake levers 250 may be connected to a hydraulic hose 241 to brake the two front wheels 1111 and 1112 and the rear wheel 112, respectively. By using multiple output ports on the hydraulic hose 241, simultaneous braking of more than two wheels can be achieved.

[0071] In some embodiments, the hydraulic fluid in the main pipe is not in communication with the hydraulic fluid in the first sub-pipe and the hydraulic fluid in the second sub-pipe. In other embodiments, the hydraulic fluid in the main pipe is in communication with the hydraulic fluid in the first sub-pipe and the hydraulic fluid in the second sub-pipe.

[0072] like Figures 1 to 3 As shown, the vehicle 001 further includes a detection component 300. The detection component 300 is disposed on the main body 100 and is configured to change state when the transmission mechanism 230 fails.

[0073] Failure modes of the transmission mechanism 230 may include damage, disconnection, and stretching. The failure modes vary depending on the structure of the transmission mechanism 230. For example, if the transmission mechanism 230 includes a brake cable 231, disconnection or stretching of the brake cable 231 can often cause the transmission mechanism 230 to fail. Furthermore, if the transmission mechanism 230 includes a hydraulic pipe 241, a disruption in the hydraulic fluid seal can cause the transmission mechanism 230 to fail. For example, a breakage or disconnection of the hydraulic pipe 241 can disrupt the hydraulic fluid seal, further causing the transmission mechanism 230 to fail.

[0074] Failure of the transmission mechanism 230 may cause the braking function of the vehicle 001 to fail or deteriorate. When the transmission mechanism 230 fails, the detection component 300 can detect the failure of the transmission mechanism 230, thereby enabling the failure of the transmission mechanism 230 to be discovered in a timely manner, facilitating the user or the vehicle 001 to take proactive countermeasures.

[0075] Figure 4 A schematic block diagram of the circuit structure of a detection component provided according to some embodiments of the present application is shown. Figure 5 FIG. 1 shows a schematic diagram of a partial side view of a vehicle according to some embodiments of the present application. Figure 4 and Figure 5 As shown, the detection component 300 includes a controller 320. The controller 320 may include at least one storage medium 322 and at least one processor 321. The at least one storage medium 322 stores at least one set of instructions. The at least one processor 321 is in communication with the at least one storage medium 322.

[0076] The storage medium 322 may include one or more of a magnetic disk, a read-only storage medium, or a random access storage medium. The storage medium 322 may also include a non-volatile random access memory.

[0077] The processor 321 may be in the form of one or more processors 321. According to some embodiments of the present specification, the processor 321 may include one or more hardware processors, such as a microcontroller, a microprocessor, a reduced instruction set computer (RISC), an application-specific integrated circuit (ASIC), an application-specific instruction set processor (ASIP), a central processing unit (CPU), a microprocessor (MCU), a graphics processing unit (GPU), a physical processing unit (PPU), a microcontroller 320 unit, a digital signal processor (DSP), a field programmable gate array (FPGA), an advanced RISC machine (ARM), a programmable logic device (PLD), any circuit or processor capable of performing one or more functions, etc., or any combination thereof.

[0078] For illustrative purposes only, only one processor 321 is described in the controller 320 in the present disclosure. However, it should be noted that the controller 320 may also include multiple processors 321. Therefore, the operations and / or method steps disclosed in the present disclosure may be performed by one processor 321 as described in the present disclosure, or may be performed jointly by multiple processors 321. For example, if the processor 321 of the controller 320 in the present disclosure performs step A and step B, it should be understood that step A and step B may also be performed jointly or separately by two different processors 321 (for example, the first processor 321 performs step A, the second processor 321 performs step B, or the first and second processors 321 perform steps A and B together).

[0079] like Figure 1 and Figure 4 As shown, vehicle 001 also includes a response component 400. Response component 400 is disposed within main body 100 and electrically connected to controller 320. Controller 320 is configured to control response component 400 to issue a prompt and / or initiate a responsive action when a state change occurs in detection component 300. Specifically, when detection component 300 detects a failure in transmission mechanism 230, controller 320 controls response component 400 to issue a prompt and / or initiate a responsive action.

[0080] In some embodiments, the response component 400 includes at least one of an alarm light, a display, a transmitting antenna, or a speaker, and the alarm light, display, transmitting antenna, or speaker can send prompt information to the user.

[0081] In some embodiments, the response component 400 includes a drive motor for driving the vehicle 001. When the detection component 300 detects that the transmission mechanism 230 fails, if the vehicle 001 is parked, the controller 320 controls the drive motor to not start or locks the drive wheels.

[0082] In some embodiments, as Figure 3 As shown, the detection assembly 300 includes a wire 301 and measures the conductive state of the wire 301 during operation. The wire 301 is disposed adjacent to the transmission mechanism 230 and extends along the extension direction of the transmission mechanism 230. When the transmission mechanism 230 fails due to breaking, the wire 301 also breaks, allowing the detection assembly 300 to detect the failure of the transmission mechanism 230 through the change in the conductive state of the wire 301.

[0083] Specifically, for a transmission mechanism 230 including a brake line 231, the wire 301 can be fixed to the brake line 231 and extend along the extension direction of the brake line 231. For a transmission mechanism 230 including a hydraulic pipe 241, the wire 301 can be fixed to the hydraulic pipe 241 and extend along the extension direction of the brake line 231. When the brake line 231 or the hydraulic pipe 241 is disconnected, the wire 301 can be disconnected together. When the wire 301 is not disconnected, the current in the wire 301 is continuous. When the wire 301 is disconnected, no current flows through the disconnected portion of the wire 301. The wire 301 is connected to the controller 320. In this way, the detection component 300 can determine whether the transmission mechanism 230 has failed based on the conductive state of the wire 301.

[0084] In some embodiments, the brake cable 231 or hydraulic hose 241 is partially exposed, creating a risk of shearing. The wire 301 can be secured to the exposed portion of the brake cable 231 or hydraulic hose 241. This reduces the material used for the wire 301 and simplifies its layout.

[0085] In some embodiments, as Figure 3 As shown, conductor 301 includes a main conductor 302, a first sub-conductor 3021, and a second sub-conductor 3022. Main conductor 302 is connected to first sub-conductor 3021 and second sub-conductor 3022, respectively. If one or both of first sub-conductor 3021 and second sub-conductor 3022 are disconnected, the conductive state of main conductor 302 changes. Main conductor 302 is connected to controller 320. By splitting conductor 301, the number of connection points between conductor 301 and controller 320 is reduced, facilitating connection of controller 320 to other circuits and simplifying the layout of conductor 301.

[0086] In some embodiments, the resistances of the first sub-conductor 3021 and the second sub-conductor 3022 may be different, and the conductive state of the main conductor 302 may change differently when the first sub-conductor 3021 and the second sub-conductor 3022 are broken.

[0087] In some embodiments, the conductor 301 includes a circuit divider 303 , and the main conductor 302 is connected to the first sub-conductor 3021 and the second sub-conductor 3022 through the circuit divider 303 .

[0088] like Figure 3 As shown, the first sub-conductor 3021 is adjacent to the first sub-brake cable 2321 and extends along the extension direction of the first sub-brake cable 2321. The second sub-conductor 3022 is adjacent to the second sub-brake cable 2322 and extends along the extension direction of the second sub-brake cable 2322. Furthermore, the first sub-conductor 3021 can be fixed to the first sub-brake cable 2321, and the second sub-conductor 3022 can be fixed to the second sub-brake cable 2322.

[0089] When first sub-brake line 2321 fails due to a break, first sub-conductor 3021 also breaks. When second sub-brake line 2322 fails due to a break, second sub-conductor 3022 also breaks. This allows detection assembly 300 to determine whether first sub-brake line 2321 and first sub-brake line 2322 have failed based on the conductive state of main conductor 302.

[0090] In some embodiments, the wire 301 includes a third sub-wire 301, which is connected to the main wire 302. The third sub-wire 301 can be configured to detect whether some parts of the transmission mechanism 230 other than the first sub-brake wire 2321 and the second sub-brake wire 2322 are broken.

[0091] In some embodiments, the first sub-conductor 3021 is adjacent to the first sub-tube and extends along the extension direction of the first sub-tube. The second sub-conductor 3022 is adjacent to the second sub-tube and extends along the extension direction of the second sub-tube. Furthermore, the first sub-conductor 3021 can be fixed to the first sub-tube, and the second sub-conductor 3022 can be fixed to the second sub-tube.

[0092] When the first sub-tube fails due to a break, the first sub-conductor 3021 is also disconnected. When the second sub-tube fails due to a break, the second sub-conductor 3022 is also disconnected. In this way, the detection assembly 300 can determine whether the first and second sub-tubes have failed based on the conductive state of the main conductor 302.

[0093] In some embodiments, the wire 301 includes a third sub-wire 301, which is connected to the main wire 302. The third sub-wire 301 can be configured to detect whether some parts of the transmission mechanism 230 other than the first sub-tube and the second sub-tube are broken.

[0094] Figure 6 The figure shows the position change of the movable part of the brake assembly according to some embodiments of the present application when the state of the transmission mechanism changes. Figure 6 In the embodiment, the transmission mechanism states from top to bottom are: working state, effective but not working state and failure state. Figure 2 and Figure 6 As shown, the brake assembly 200 includes a movable portion 214 connected to the transmission mechanism 230 and changes position when the transmission mechanism 230 fails. The detection assembly 300 includes a position sensor 311 configured to detect the position change of the movable portion 214.

[0095] The movable portion 214 can be disposed on the transmission mechanism 230. For example, the movable portion 214 is disposed on the brake line 231. The movable portion 214 can also be located on the brake mechanism 210 and indirectly connected to the transmission mechanism 230 through the brake mechanism 210. For example, the movable portion 214 is a rocker arm of a drum brake structure.

[0096] When the transmission mechanism 230 is not failing, both the transmission mechanism 230 and the brake mechanism 210 are in a tense state, meaning that tension is present within both the transmission mechanism 230 and the brake mechanism 210. When the transmission mechanism 230 fails, the tension within these mechanisms disappears, and the transmission mechanism 230 and the brake mechanism 210 may be in a relaxed state. The transition of the transmission mechanism 230 and the brake mechanism 210 from a tense to a relaxed state may cause the position of the movable portion 214 to change. The position sensor 311 may be connected to the controller 320. Therefore, the controller 320 can detect the position change of the movable portion 214 via the position sensor 311 and thereby determine whether the transmission mechanism 230 has failed.

[0097] In some embodiments, the position sensor 311 includes a magnetostrictive position sensor 311 , an optical position sensor 311 , or a Hall effect-based magnetic position sensor 311 .

[0098] In some embodiments, as Figure 5 and Figure 6 As shown, the main body 100 includes a base 101. The movable portion 214 is movably connected to the base 101. Further, the movable portion 214 is rotatably connected to the base 101.

[0099] The transmission mechanism 230 includes a brake line 231 or a hydraulic tube 241. The movable portion 214 is connected to the brake line 231 or the hydraulic tube 241 and is driven by the fluid in the brake line 231 or the hydraulic tube 241 to move relative to the base 101. A position sensor 311 is provided on the base 101 and is configured to detect changes in the position of the movable portion 214 relative to the base 101.

[0100] Furthermore, the base 101 can be used to mount the movable portion 214 and the position sensor 311. When the transmission mechanism 230 drives the braking mechanism 210 to perform braking operation, the movable portion 214 can move in a first direction D1. When the transmission mechanism 230 fails, the movable portion 214 can move in a second direction D2 to a preset position. The second direction D2 is opposite to the first direction D1. The position sensor 311 is configured to detect whether the movable portion 214 is in a preset position. When the position sensor 311 detects that the movable portion 214 is in the preset position, it sends a detection signal to the controller 320.

[0101] In some embodiments, a marking hole 2141 is formed on the movable portion 214 , and the position sensor 311 determines whether the movable portion 214 is at a preset position by detecting the position of the marking hole 2141 .

[0102] In some embodiments, the base 101 is located at the wheel hub and can be used to install a drum brake structure.

[0103] Figure 7 Schematic diagram of a pressure sensor measuring hydraulic pressure in a hydraulic pipe according to some embodiments of the present application is shown. Figure 2 、 Figure 5 and Figure 7 As shown, the brake assembly 200 includes a load portion 215 connected to a transmission mechanism 230. When the transmission mechanism 230 fails, the load portion 215 undergoes a load change. The detection assembly 300 includes a pressure sensor 312 configured to detect the load change of the load portion 215.

[0104] When the transmission mechanism 230 fails, the transmission mechanism 230 and the brake mechanism 210 switch from a tensed state to a relaxed state, causing the tension within the transmission mechanism 230 and the brake mechanism 210 to change. Specifically, the transmission mechanism 230 and the brake mechanism 210 may include a load portion 215, and when the transmission mechanism 230 fails, the load within the load portion 215 changes. The pressure sensor 312 is configured to detect the load change within the load portion 215. Specifically, the pressure sensor 312 can detect the tension change within the transmission mechanism 230 and the brake mechanism 210. The pressure sensor 312 may be connected to the controller 320. The controller 320 can determine whether the transmission mechanism 230 has failed based on the detection signal from the pressure sensor 312.

[0105] In some embodiments, as Figure 2 and Figure 5 As shown, the transmission mechanism 230 includes a brake cable 231. The load portion 215 is located on the brake cable 231. A pressure sensor 312 is connected to the brake cable 231. If the brake cable 231 is disconnected or stretched, the transmission mechanism 230 will fail, and the tension within the brake cable 231 will decrease or return to zero. The pressure sensor 312 can determine the change in tension within the brake cable 231 by detecting changes in the load on the load portion 215, thereby determining whether the transmission mechanism 230 has failed.

[0106] In some embodiments, the load portion 215 is located at an end of the brake cable 231 close to the brake handle 250 , and the pressure sensor 312 can be disposed on the brake handle 250 .

[0107] In some embodiments, the load portion 215 is located at an end of the brake cable 231 close to the brake mechanism 210 , and the pressure sensor 312 can be disposed at the wheel hub.

[0108] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 As shown, transmission mechanism 230 includes a brake cable 231. Braking mechanism 210 includes a movable portion 214, which is connected to brake cable 231 and is driven by brake cable 231 to move relative to at least one wheel, thereby restricting the rotation of at least one wheel. For example, movable portion 214 is a rocker arm or a drum brake of a drum brake structure.

[0109] The load-bearing portion 215 is located on the movable portion 214, and the pressure sensor 312 is connected to the movable portion 214. When the transmission mechanism 230 drives the brake mechanism 210 to brake, the movable portion 214 can move in a first direction D1, increasing the load on the load-bearing portion 215. If the transmission mechanism 230 fails, the movable portion 214 can move in a second direction D2, decreasing or returning the load on the load-bearing portion 215 to zero. The second direction D2 is opposite to the first direction D1. The pressure sensor 312 can determine the change in tension within the brake mechanism 210 by detecting the change in load on the load-bearing portion 215, thereby determining whether the transmission mechanism 230 has failed.

[0110] In some embodiments, the transmission mechanism 230 is a hydraulic transmission structure. Figure 7 As shown, the hydraulic transmission structure forms a receiving space 242 for accommodating liquid. The load portion 215 is located on the peripheral wall of the receiving space 242, and the pressure sensor 312 is configured to detect changes in the load applied by the liquid within the receiving space 242 to the peripheral wall of the receiving space 242. In other words, the pressure sensor 312 is configured to detect the hydraulic pressure of the hydraulic fluid. For example, the transmission mechanism 230 includes a hydraulic tube 241, the receiving space 242 is located within the hydraulic tube 241, and the load portion 215 is the tube wall of the hydraulic tube 241.

[0111] A prerequisite for hydraulic transmission is effective sealing of the hydraulic fluid. Damage or disconnection of hydraulic pipe 241 disrupts the hydraulic fluid's sealing environment, leading to a decrease in the hydraulic pressure and failure of transmission mechanism 230. By detecting the hydraulic pressure, pressure sensor 312 can determine changes in the hydraulic fluid's sealing environment and, therefore, determine whether transmission mechanism 230 has failed.

[0112] In some embodiments, the probe of the pressure sensor 312 is located in the hydraulic pipe 241. Alternatively, the probe of the pressure sensor 312 is located in the hydraulic cylinder of the hydraulic transmission structure.

[0113] In summary, the vehicle 001 provided in this specification can detect the failure of the transmission mechanism 230 through the detection component 300 when the transmission mechanism 230 fails, so that the failure of the transmission mechanism 230 can be discovered in time, making it easier for the user or the vehicle 001 to take active countermeasures.
