Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle brake simulation detection, and in particular to a rapid detection mechanism applied to the brake simulation working conditions of electric vehicles. Background Art

[0002] With the increasing technology of electric vehicles in recent years, the popularity rate of electric vehicles has increased rapidly. The safety of electric vehicles has attracted more and more attention from consumers.

[0003] Among them, the braking system of electric vehicles plays a crucial role in the operation of the vehicle, which is directly related to the safety of electric vehicle driving. The braking system of electric vehicles includes a traditional brake disc and realizes braking through the reverse dragging action of the motor, while recovering the energy during the braking process. At present, the braking system of electric vehicles mainly consists of a brake system, brake pads and a brake disc. In order to ensure the stability of the braking system, it is necessary to detect the braking system during the production and R & D stages. The traditional detection method is to directly install the braking system on the simulated wheel, and then judge its effect through braking operation. This detection method is not only cumbersome to operate, but also unable to quickly load and unload the brake disc, with low adaptability. At the same time, it cannot truly simulate different operating conditions, resulting in poor simulation detection accuracy and incomplete data. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional detection method is not only cumbersome to operate, but also unable to quickly load and unload the brake disc, with low adaptability. At the same time, it cannot truly simulate different operating conditions, resulting in poor simulation detection accuracy and incomplete data.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a rapid detection mechanism applied to the brake simulation working conditions of electric vehicles, including a main assembly frame. An inner drive motor is fixedly installed on the inner wall of the main assembly frame. A first translation support rod, a second translation support rod and a third translation support rod are respectively installed on the inner wall of the main assembly frame outside the inner drive motor. A front-mounted assembly frame with an L-shaped structure is welded and fixed at the front end of the main assembly frame. A quick-install inner transmission disc for installing the electric vehicle brake disc is movably assembled on the inner side surface of the front-mounted assembly frame. The extending end of the first translation support rod is axially fixed with a first assembly frame for installing the electric vehicle brake. The extending end of the second translation support rod is axially fixed with a second assembly frame for installing an electric control reciprocating detection module. The extending end of the third translation support rod is axially fixed with a third assembly frame for installing an environment simulation module.

[0006] The quick-install inner transmission disc includes a main mounting seat movably connected by a movable shaft to the inner side of the front-mounted assembly frame, a lateral positioning column fixed on the side wall of the main mounting seat, and a secondary synchronous disc sleeved on the lateral positioning column.

[0007] A lateral telescoping machine is fixedly installed on the main assembly frame on the side of the inner drive motor, and a drive shaft sleeve controlled by the lateral telescoping machine is axially sleeved on the front drive shaft of the inner drive motor.

[0008] The electric control reciprocating detection module includes embedded guide rails fixedly installed on the inner walls on both sides of the second assembly frame, an electric control lead screw installed inside the embedded guide rails, an internally threaded translation seat threadedly sleeved on the electric control lead screw, and an optical recognition module and a temperature and humidity detection module fixedly installed on the internally threaded translation seat.

[0009] The environmental simulation module includes strip-shaped nozzles fixedly installed on the inner walls on both sides of the third assembly frame, a lateral air input pipe fixedly installed at one end of the strip-shaped nozzle, a lateral liquid input pipe fixedly installed at the other end of the strip-shaped nozzle, an embedded electric heating plate fixedly installed on the inner side surface of the strip-shaped nozzle, and an embedded semiconductor refrigeration module.

[0010] The contact surface between the auxiliary synchronous disk and the drive shaft sleeve is a conical structure that matches each other.

[0011] Press switches for controlling the forward and reverse rotation of the electric control lead screw are installed at both inner ends of the embedded guide rail.

[0012] The drive shaft sleeve includes a sliding control sleeve axially sleeved on the front drive shaft of the inner drive motor, an external control ring movably sleeved outside the sliding control sleeve, and an external control seat fixedly installed on the outer side surface of the external control ring. The extending end of the lateral telescoping machine is inserted into the external control seat and fixedly assembled with the external control seat.

[0013] Arc-shaped protective covers are fixedly installed on the side walls of the first assembly frame, the second assembly frame, and the third assembly frame.

[0014] An internal assembly through hole matching the lateral positioning column is opened inside the auxiliary synchronous disk, and a lateral compression spring is installed on the side wall of the auxiliary synchronous disk around the internal assembly through hole.

[0015] The beneficial effects of the present invention are:

[0016] (1) By adopting the design of an electric control translation strut to control the translation adjustment of the assembly frame, the rapid detection mechanism applied to the brake simulation working condition of an electric vehicle can quickly cooperate with and separate from the brake disc, greatly facilitating the loading and unloading of the brake disc;

[0017] (2) Separating the assembly mechanism and the drive mechanism of the brake disc can improve the safety during the assembly process;

[0018] (3) By adopting the clutch cooperation between the auxiliary synchronous disk and the drive shaft sleeve on the front drive shaft of the inner drive motor, and using a non-rigid connection method for driving, the damage to the drive unit during the braking process can be avoided, and the service life of the drive unit can be extended;

[0019] (4) An electronically controlled reciprocating detection module is installed inside the second assembly frame. When the brake disc rotates, the wear degree, temperature, and humidity of the brake disc surface can be monitored from both sides, so as to quickly and real-time detect the changes of the brake disc, and improve the comprehensiveness and accuracy of the detection values;

[0020] (5) An environment simulation module is installed inside the third assembly frame, which can adjust the temperature and humidity of the brake disc surface as needed, so as to simulate different operating conditions, and can truly detect the operating stability of the braking system under different conditions, making the detection data more comprehensive;

[0022] (7) The electronically controlled reciprocating detection module can not only monitor the operating conditions and surface states of the brake disc, but also monitor the operating stability of the brake disc, greatly improving its operating safety. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4 A rapid detection mechanism applied to the braking simulation condition of an electric vehicle as shown includes a main assembly frame 1. An inner drive motor 2 is fixedly installed on the inner wall of the main assembly frame 1. A first translation support rod 3, a second translation support rod 4, and a third translation support rod 5 are respectively installed on the inner wall of the main assembly frame 1 outside the inner drive motor 2. An L-shaped front assembly frame 6 is welded and fixed to the front end of the main assembly frame 1. A quick-install inner transmission disk 7 for installing the brake disk of the electric vehicle is movably assembled on the inner side surface of the front assembly frame 6. The extending end of the first translation support rod 3 is axially fixed with a first assembly frame 9 for installing the electric vehicle brake 8. The extending end of the second translation support rod 4 is axially fixed with a second assembly frame 11 for installing an electric control reciprocating detection module 10. The extending end of the third translation support rod 5 is axially fixed with a third assembly frame 13 for installing an environment simulation module 12.

[0031] Operating principle: First, the electric vehicle brake 8, the electric control reciprocating detection module 10, and the environment simulation module 12 are respectively translated outward through the first translation support rod 3, the second translation support rod 4, and the third translation support rod 5. Then, the brake disk is installed on the quick-install inner transmission disk 7. Then, the electric vehicle brake 8, the electric control reciprocating detection module 10, and the environment simulation module 12 are respectively translated inward through the first translation support rod 3, the second translation support rod 4, and the third translation support rod 5 and installed outside the brake disk. The inner drive motor 2 is used to drive the quick-install inner transmission disk 7 to rotate. When rotating, a braking force is formed through the electric vehicle brake 8, thereby simulating a braking scenario. Then, the state change on the surface of the brake disk during braking is detected to judge the quality of the braking system.

[0032] In order to cooperate with rapid assembly, the quick-install inner transmission disk 7 includes a main mounting seat 71 movably connected by a movable shaft to the inner side of the front assembly frame 6, a lateral positioning column 72 fixed on the side wall of the main mounting seat 71, and a secondary synchronous disk 73 sleeved on the lateral positioning column 72.

[0033] The mounting hole on the brake disk is directly sleeved on the lateral positioning column 72, then attached to the inner side of the main mounting seat 71, and then the secondary synchronous disk 73 is sleeved on the lateral positioning column 72 from the other side for assembly.

[0034] To cooperate with the linkage control, a lateral telescoping machine 14 is fixedly installed on the main assembly frame 1 on the side of the inner drive motor 2, and a drive shaft sleeve 15 controlled by the lateral telescoping machine 14 is axially sleeved on the front drive shaft of the inner drive motor 2.

[0035] The lateral telescoping machine 14 squeezes the auxiliary synchronous disk 73 from the inside by controlling the drive shaft sleeve 15, and then uses the inner drive motor 2 to control the drive shaft sleeve 15 to drive the auxiliary synchronous disk 73 to rotate.

[0036] To cooperate with the reciprocating control, the electric control reciprocating detection module 10 includes embedded guide rails 101 fixedly installed on the inner walls on both sides of the second assembly frame 11, an electric control lead screw 102 installed inside the embedded guide rails 101, an internally threaded translation seat 103 threadedly sleeved on the electric control lead screw 102, and an optical recognition module 104 and a temperature and humidity detection module 105 fixedly installed on the internally threaded translation seat 103.

[0037] The electric control lead screw 102 is a prior art and is rotated by electric control to control the internally threaded translation seat 103 to translate along the embedded guide rails 101.

[0038] To cooperate with the simulation of the working conditions environment, the environment simulation module 12 includes strip nozzles 121 fixedly installed on the inner walls on both sides of the third assembly frame 13, a lateral air input pipe 122 fixedly installed at one end of the strip nozzle 121, a lateral liquid input pipe 123 fixedly installed at the other end of the strip nozzle 121, an embedded electric heating plate 124 and an embedded semiconductor refrigeration module 125 fixedly installed on the inner side surface of the strip nozzle 122.

[0039] The lateral air input pipe 122 is used to transport high-pressure air, simulate the operating state by injecting air inside the strip nozzle 121, and then adjust the internal temperature through the embedded electric heating plate 124 and the embedded semiconductor refrigeration module 125. The embedded electric heating plate 124 and the embedded semiconductor refrigeration module 125 are prior arts. The embedded electric heating plate 124 is used for heating up, and the embedded semiconductor refrigeration module 125 is used for cooling down.

[0040] The lateral liquid input pipe 123 is used to transport high-pressure water, and simulate the rainy state by injecting liquid inside the strip nozzle 121.

[0041] To increase the contact area and improve the driving efficiency, the contact surfaces of the auxiliary synchronous disk 73 and the drive shaft sleeve 15 are mutually matching frustum-shaped structures.

[0042] The contact surface of the drive shaft sleeve 15 protrudes once towards the auxiliary synchronous disk 73, and the contact surface on one side of the auxiliary synchronous disk 73 is recessed inward.

[0043] To cooperate with the automatic reciprocating control, pressure switches 16 for controlling the forward and reverse rotation of the electric control screw rod 102 are installed at both ends inside the embedded guide rail 101.

[0044] The rotation of the electric control screw rod 102 controls the translation of the internal thread translation seat 103 along the embedded guide rail 101. When the internal thread translation seat 103 presses against the pressure switch 16 on one side, the pressure switch 16 will control the electric control screw rod 102 to rotate in the reverse direction, so as to achieve the purpose of reciprocating operation.

[0045] To cooperate with the sliding adjustment, the drive shaft sleeve 15 includes a sliding control sleeve 151 axially sleeved on the front drive shaft of the inner drive motor 2, an external control ring 152 movably sleeved outside the sliding control sleeve 151, and an external control seat 153 fixedly installed on the outer side surface of the external control ring 152. The extending end of the lateral telescoping machine 14 is inserted into the external control seat 153 and fixedly assembled with the external control seat 153.

[0046] The lateral telescoping machine 14 controls the translation adjustment of the external control seat 153 and the external control ring 152 connected thereto through telescoping, and then uses the external control ring 152 to drive the sliding control sleeve 151 to slide on the front drive shaft of the inner drive motor 2. The sliding control sleeve 151 can translate and slide on the front drive shaft of the inner drive motor 2, but is rotationally limited. Therefore, when the front drive shaft of the inner drive motor 2 rotates, the sliding control sleeve 151 also rotates accordingly.

[0047] To cooperate with blocking impurities and liquids thrown outwards from the surface when the brake disc rotates at high speed, arc-shaped protective covers 17 are fixedly installed on both side walls of the first assembly frame 9, the second assembly frame 11, and the third assembly frame 13.

[0048] The arc-shaped protective cover 17 is arranged around the brake disc, leaving a certain distance from the brake disc.

[0049] To improve the lateral extrusion stability and shock absorption, an internal assembly through hole matching the lateral positioning column 72 is opened inside the secondary synchronous disc 73, and a lateral extrusion spring 74 is installed on the side wall of the secondary synchronous disc 73 around the internal assembly through hole.

[0050] By sleeving the lateral extrusion spring 74 around the lateral positioning column 72 and squeezing one side of the brake disc, while ensuring the lateral extrusion force, it is convenient to disassemble the secondary synchronous disc 73.

[0051] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
