Description

Technical Field

[0001] The present invention belongs to the technical field of brake detection, and in particular relates to a brake detection device for a new energy vehicle. Background Art

[0002] Automobile brake disc runout detection is an important part of ensuring driving safety. By detecting the brake disc runout, problems with the brake disc, such as wear, deformation, imbalance, etc., can be discovered in time, thereby ensuring the stability and safety of the brake system.

[0003] Especially for new energy vehicles, compared with traditional fuel vehicles, the brake discs of new energy vehicles wear out faster because there is no engine braking assistance. Therefore, it is very necessary to perform brake disc vibration detection on new energy vehicles.

[0004] A common way to detect the amount of runout is to use a dial indicator, which is to attach the magnetic base to the car's connecting rod or shock absorber, etc., fix the dial indicator on the car, and place the detection end of the dial indicator against the end face of the brake disc. When the wheel rotates, the amount of runout of the brake disc can be determined by the indication of the dial indicator.

[0005] This detection method can realize the detection of brake discs without disassembling them, so it is widely used. However, the disadvantage of this detection method is that the magnetic base is fixed by magnetic adsorption. However, due to the irregular adsorption surface or contamination with mud, the magnetic base may not be firmly adsorbed on the surface of the car, thereby increasing the risk of errors in the measurement of the dial indicator. In summary, how to improve the reliability of the fixation of the dial indicator on the car is a technical problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0034] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] See also Figure 1-Figure 4 The embodiment of the present application provides a new energy vehicle brake detection device, including a first housing 1, a second housing 2, an elastic component, a locking component and a measuring component 6. The first housing 1 is an arc-shaped structure, and along the arc length direction of the first housing 1, the first housing 1 is provided with an arc-shaped through groove 11, and the arc-shaped through groove 11 includes a first end 113 and a second end 114.

[0036] The second shell 2 is an arc-shaped structure. The second shell 2 includes an elastic material. Along the arc length direction of the second shell 2, the second shell 2 includes a third end 25 and a fourth end 26. The third end 25 is inserted into the arc-shaped through groove 11 via the first end 113. The second shell 2 is provided with a matching portion 21. The elastic component includes a first movable seat 12, a second movable seat 15 and a first elastic member 14. Along the arc length direction of the first shell 1, the first movable seat 12 and the second movable seat 15 are movably connected to the arc-shaped through groove 11. The first movable seat 12 is close to the first end 113. The first elastic member 14 connects the first movable seat 12 and the second movable seat 15. The arc-shaped through groove 11 is provided with two limiting portions 13. The first movable seat 12 and the second movable seat 15 are arranged between the two limiting portions 13. The matching portion 21 is configured so that when the third end 25 is inserted into the arc-shaped through groove 11, the matching portion 21 pushes the first movable seat 12 to move toward the second movable seat 15. The second movable seat 15 is configured so that when the fourth end 26 is inserted into the arc-shaped through groove 11 via the second end 114, the fourth end 26 is detachably connected to the second movable seat 15.

[0037] The locking component is used to lock or unlock the second housing 2 , and the measuring component 6 is connected to the first housing 1 .

[0038] The third end 25 of the second shell 2 is inserted into the arc-shaped through slot 11 via the first end 113 of the first shell 1 , so that the second shell 2 can rotate relative to the first shell 1 , thereby allowing the first shell 1 and the second shell 2 to form two states.

[0039] One state is that the third end 25 of the second shell 2 moves in the direction of rotating out of the arcuate through slot 11, and the fourth end 26 is inserted into the arcuate through slot 11 via the second end 114. At this time, the first shell 1 and the second shell 2 can form a sleeve-like structure, which can be mounted on certain parts of a car. For example, the sleeve-like structure can be mounted on the cylindrical structure of a car shock absorber, so that the measuring part 5 can be fixed to the car to detect the brake disc runout. Compared with the traditional magnetic table seat, the fixing reliability of the measuring component 6 is increased, thereby improving the detection accuracy of the brake disc runout.

[0040] Another state is when the third end 25 moves in the direction of being screwed into the arc-shaped through slot 11 , at which time the sleeve-like structure is opened and the measuring assembly 6 can be removed from the vehicle.

[0041] The movably connecting structures of the first movable seat 12 and the second movable seat 15 and the arc-shaped channel can be selected from existing structures, which will not be described in detail here.

[0042] The first elastic member 14 may be a spring.

[0043] The first movable seat 12 and the second movable seat 15 move between the two limit portions 13, so that the elastic component can have two working states. One state is that the first movable seat 12 moves toward the direction close to the second movable seat 15, and at this time, the first movable seat 12 has a tendency to move in the reverse direction. The other state is that the second movable seat 15 moves toward the direction close to the first movable seat 12, and at this time, the second movable seat 15 has a tendency to move in the reverse direction.

[0044] When the third end 25 of the second shell 2 moves into the arc channel, the matching portion 21 pushes the first movable seat 12 to move toward the second movable seat 15. When the first elastic member 14 is compressed to a certain extent, the second shell 2 is locked by the locking component. When the inner wall surface of the first shell 1 is pressed against the automobile component, the locking component unlocks the second shell 2 again. At this time, under the action of the elastic restoring force of the first elastic member 14, the fourth end 26 of the second shell 2 moves toward the second end 114 of the first shell 1.

[0045] Taking the tubular structure in which the first shell 1 and the second shell 2 are sleeved on the shock absorber of the car as an example, the tubular structure part faces the inner fender of the car. If the second shell 2 needs to be rotated manually, then when the second shell 2 is rotated manually, the user is more likely to touch the inner fender of the car with the hand or sleeve, causing the hand or sleeve to be contaminated with dirt. On the one hand, it is inconvenient to use. On the other hand, the measuring component 6 is a relatively precise device. If the hand is contaminated with dirt and then touches the measuring component 6, the risk of damage to the measuring component 6 will increase.

[0046] When the elastic component of the embodiment of the present application presses the inner wall surface of the first shell 1 against the automobile part, the second shell 2 can be popped out by unlocking the second shell 2, and the fourth end 26 of the second shell 2 can be bounced toward the second end 114 of the first shell 1. The user does not need to manually push the second shell 2 to the second end 114, thereby reducing the risk of the user's hands or sleeves coming into contact with the inner fender of the car, causing the hands or sleeves to be contaminated with dirt.

[0047] When the fourth end 26 of the second shell 2 is inserted into the second end 114 of the first shell 1, the second shell 2 can be pushed so that the fourth end 26 of the second shell 2 can be connected to the second movable seat 15. Since the second shell 2 includes an elastic material, on the one hand, by driving the second movable seat 15 to move toward the first movable seat 12, the size of the sleeve structure surrounded by the first shell 1 and the second shell 2 can be reduced, thereby increasing the fixing effect. On the other hand, when the second movable seat 15 moves toward the first movable seat 12, the first elastic member 14 is compressed. When the detection is completed, the second movable seat 15 and the fourth end 26 are disconnected, and the limit on the second movable seat 15 is released. When the second movable seat 15 is reset, the fourth end 26 can be pushed out of the arc groove 11, thereby reducing the risk of the user's hands or sleeves contacting the inner fender of the car, causing the hands or sleeves to be contaminated with dirt.

[0048] The measuring component 6 may include a dial indicator. The specific process and principle of the dial indicator for measuring the brake disc runout are well known to those skilled in the art and will not be described in detail here.

[0049] In order to prevent the third end 25 of the second shell 2 from escaping from the arcuate slot 11 , a limiting structure may be provided inside the arcuate slot 11 . The limiting structure may be selected from existing structures and will not be described in detail herein.

[0050] See also Figure 4 , Figure 5 , Figure 6 and Figure 8 In some embodiments, the locking component includes a locking block 116, a rotating block 112, and a second elastic member. The inner peripheral wall of the first shell 1 is provided with a first through hole 111, the first through hole 111 is communicated with the interior of the arc-shaped through groove 11, and the locking block 116 is arranged in the first through hole 111. The rotating block 112 is penetrated by the first through hole 111, and the rotating block 112 is provided with a strip groove 115, the strip groove 115 extends along the radial direction of the first shell 1, and the locking block 116 is accommodated in the strip groove 115, the strip groove 115 includes two oppositely arranged side wall surfaces, the locking block 116 includes at least one abutting plane, the abutting plane abuts against the side wall surface, the end of the strip groove 115 close to the center of the first shell 1 is a circular end, and the locking block 116 is configured to rotate relative to the locking block 116 when it moves into the circular end, and the inner peripheral wall of the second shell 2 is provided with a recessed portion 27, and the side of the rotating block 112 away from the center of the first shell 1 is accommodated in the recessed portion 27. The second elastic member connects the locking block 116 and the rotating block 112 .

[0051] The first through hole 111 allows the rotating block 112 to be partially disposed inside the first housing 1 , so that when the inner wall surface of the first housing 1 abuts against an automobile component, the automobile component can push the rotating block 112 to move.

[0052] The abutting plane cooperates with the side wall of the strip groove 115 so that the rotating block 112 cannot rotate relative to the locking block 116 and can only move along the strip groove 115 . At this time, the rotating block 112 is in the recess 27 and the second housing 2 is locked by the rotating block 112 .

[0053] At the same time, the rotating block 112 cannot rotate relative to the locking block 116 and can only move along the strip groove 115, so that when the rotating block 112 is pressed by the automobile parts, the depth of the rotating block 112 inserted into the recessed portion 27 increases, thereby increasing the subsequent travel of the rotating block 112 to push the second shell 2 to move.

[0054] Under the action of automobile parts, when the rotating block 112 is pressed until the locking block 116 moves into the circular end, the rotating block 112 can rotate around the locking block 116. By reasonably setting the shape of the rotating block 112, the rotating block 112 can rotate in a specified direction, that is, the third end 25 of the second shell 2 can be pushed by the rotating block 112 to move further toward the direction close to the second end 114 of the first shell 1. At this time, the compression degree of the first elastic member 14 increases until the rotating block 112 is screwed out of the recessed portion 27.

[0055] The advantage of this arrangement is that, on the one hand, the second shell 2 is pushed a certain distance before unlocking the second shell 2, which can reduce the risk of the second shell 2 getting stuck in the arc-shaped through groove 11, so that the second shell 2 can be ejected smoothly. On the other hand, the compression degree of the first elastic member 14 is increased, which increases the ejection effect of the second shell 2.

[0056] The second elastic member may be a spring. The second elastic member is used to enable the rotating block 112 to return to its original position after the force exerted by the automobile component on the rotating block 112 disappears.

[0057] See also Figure 5 In some embodiments, the end of the rotating block 112 close to the center of the first shell 1 is tilted.

[0058] by Figure 4 and Figure 5 As shown in the example, the end of the rotating block 112 close to the center of the first shell 1 can extend toward the center of the first shell 1 and be inclined toward the first end 113 of the first shell 1 .

[0059] The end of the rotating block 112 is tilted so that the automobile component pushes the rotating block 112 to move until the locking block 116 enters the circular end of the strip groove 115, and the rotating block 112 can rotate in a specified direction.

[0060] See also Figure 3In some embodiments, a first hook 24 is provided at the fourth end 26 of the second shell 2, and a second hook 19 is rotatably provided at the second movable seat 15. The second hook 19 is hooked on a side of the first hook 24 close to the second shell 2, and a third elastic member is provided between the second hook 19 and the second movable seat 15. The third elastic member is used to keep the second hook 19 against the first hook 24. The second hook 19 is provided with a supporting portion 110. The supporting portion 110 is configured such that when the second hook 19 hits the limiting portion 13 close to the second end 114, the second hook 19 is pushed to rotate so as to separate the first hook 24 from the second hook 19.

[0061] The specific hook structures of the first hook portion 24 and the second hook portion 19 can be selected from existing structures to meet the requirements.

[0062] The second hook 19 is rotatably connected to the second movable seat 15, so that when the first hook 24 approaches the second hook 19 from the second end 114 of the first housing 1, the first hook 24 can push the second hook 19 to rotate, thereby enabling the first hook 24 and the second hook 19 to hook together. In order to facilitate pushing the second hook 19, the first hook 24 can be provided with an inclined surface as shown in the figure.

[0063] When the first hook portion 24 and the second hook portion 19 are hooked together, the fourth end 26 of the second housing 2 can be pulled by the second movable seat 15 to increase the degree of tightening of the first housing 1 and the second housing 2 on the automobile component.

[0064] When the detection is completed, the lock of the second movable seat 15 is unlocked. At this time, the second movable seat 15 moves toward the limiting portion 13 close to the second end 114 of the first shell 1 until the abutting portion 110 of the second hook 19 hits the limiting portion 13, so that the second hook 19 can rotate in the direction away from the first hook 24, and the first hook 24 and the second hook 19 are unhooked, so that under the action of the elastic restoring force of the second shell 2 itself and the elastic restoring force of the first elastic member 14, the fourth end 26 of the second shell 2 can withdraw from the arc-shaped through groove 11.

[0065] See also Figure 2 In some embodiments, a driving unit 16 is further included. The driving unit 16 is movably disposed on the first shell 1 along the arc length direction of the first shell 1 , and the second movable seat 15 is detachably connected to the driving unit 16 .

[0066] The specific movably connected structure of the driving part 16 and the first shell 1 can be selected from existing structures and will not be described in detail here.

[0067] A locking structure is provided between the driving part 16 and the first housing 1 to lock or unlock the driving part 16. The locking structure can be selected from existing structures and will not be described in detail here.

[0068] The driving part 16 may be disposed outside the first housing 1, and the first housing 1 may be provided with a third through hole 17, and the driving part 16 and the second movable seat 15 are connected via the third through hole 17. Since the second movable seat 15 is disposed in the arc-shaped through groove 11, the driving part 16 is convenient for driving the second movable seat 15 to move.

[0069] The driving part 16 and the second movable seat 15 can be detachably connected by a latch 18, that is, the driving part 16 is movably provided with a latch 18, and the second movable seat 15 is provided with a pin hole. When the latch 18 is inserted into the pin hole, the driving part 16 and the second movable seat 15 are fixed to each other. Conversely, when the latch 18 is withdrawn from the pin hole, the second movable seat 15 and the driving part 16 are disconnected.

[0070] See also Figure 7 , Fig. 9 and Fig.10 In some embodiments, the second shell 2 includes a flexible body 22, two elastic support parts 210 and a connecting terminal 23. The flexible body 22 is an arc-shaped structure. Along the arc length direction of the flexible body 22, the flexible body 22 is provided with a second through hole 211, and the second through hole 211 is arranged at two intervals along the axial direction of the flexible body 22. The two elastic support parts 210 are arranged in the second through hole 211 in a one-to-one correspondence. There are two connecting terminals 23, and the two connecting terminals 23 are respectively arranged on both sides of the arc length direction of the flexible body 22. The connecting terminal 23 is provided with a mounting groove 29, and a connecting member 28 is arranged in the mounting groove 29, and the connecting member 28 connects the two elastic support parts 210.

[0071] The flexible body 22 can be selected from existing products, for example, the flexible body 22 can be rubber. It should be noted that if the flexible body 22 is rubber, in order to reduce the friction between the flexible body 22 and the inner wall of the arc-shaped through groove 11, the surface of the flexible body 22 can be provided with a friction-reducing coating.

[0072] The elastic support portion 210 is made of a material capable of generating elastic deformation, such as spring steel.

[0073] The elastic support portion 210 is used to support the flexible body 22 so that the flexible body 22 can maintain an arc-shaped structure.

[0074] The connection terminal 23 can be used to install components of the second housing 2 . For example, the first hook 24 can be disposed on the connection terminal 23 .

[0075] Taking the flexible body 22 spread out into a rectangle as an example, the arc length direction of the flexible body 22 may be the length direction of the flexible body 22 , and the axial direction of the flexible body 22 may be the width direction of the flexible body 22 .

[0076] The mounting groove 29 may partially extend along the axial direction of the flexible body 22 .

[0077] The connection end 23 may be composed of two parts, and the two parts are matched so that a mounting groove 29 can be formed inside the connection end 23 .

[0078] Two sides of the connecting member 28 may be connected to two elastic supporting parts 210 respectively.

[0079] The two elastic support parts 210 are connected by the connecting piece 28 so that the flexible body 22 can be connected to the connecting end 23 .

[0080] The second housing 2 includes a flexible body 22 , so that the second housing 2 can fully contact the outer surface of the automobile component, thereby increasing the fixing effect on the measuring component 6 .

[0081] See also Fig. 9 In some embodiments, the side wall surface of the mounting groove 29 close to the flexible body 22 is an arc surface with the concave side facing the flexible body 22 .

[0082] The connecting member 28 may be a connecting cable.

[0083] The side wall surface of the installation groove 29 close to the flexible body 22 is an arc surface with the inner concave side facing the flexible body 22 so that there is a gap between the connecting member 28 and the side wall surface of the installation groove 29 close to the flexible body 22 .

[0084] The side wall surface of the mounting groove 29 close to the flexible body 22 is an arc surface with the concave side facing the flexible body 22, so that when a force is applied to separate the two connecting ends 23, the two elastic support parts 210 tend to approach each other. When the two elastic support parts 210 approach each other, the width of the flexible body 22 is reduced and the thickness is increased, so that the degree of tightening of the first shell 1 and the second shell 2 on the automobile parts can be increased, thereby increasing the fixing effect of the measuring component 6.

[0085] In order to allow the flexible body 22 to protrude toward the automobile component when the width of the flexible body 22 is reduced, the second through hole 211 may be disposed on a side of the flexible body 22 facing away from the automobile component along the thickness direction of the flexible body 22 .

[0086] See also Figure 1 In some embodiments, the measuring assembly 6 includes a supporting arm 3, a measuring portion 5 and a mounting portion 4. The supporting arm 3 is connected to the first housing 1, and the mounting portion 4 connects the measuring portion 5 and the supporting arm 3.

[0087] The support arm 3 is used to adjust the position of the measuring part 5 relative to the first shell 1. The support arm 3 can adopt the arm structure of a common magnetic stand, and its structure is well known to those skilled in the art and will not be described in detail here.

[0088] The measuring part 5 is used to measure the runout of the brake disc, that is, the measuring part 5 can be a dial indicator. By placing the measuring end of the dial indicator against the end face of the brake disc, when the brake disc rotates, the indication of the dial indicator changes, so that the runout of the brake disc can be measured by the dial indicator.

[0089] See also Figure 1 and Fig.11 In some embodiments, the mounting portion 4 is provided with a notch slot 41 , and the measuring portion 5 is inserted into the notch slot 41 .

[0090] The measuring part 5 is inserted into the notch groove 41 , so that the measuring part 5 can be detachably connected to the mounting part 4 .

[0091] See also Fig.11 In some embodiments, the notch channel 41 includes two arms that are disposed opposite to each other, and a plurality of arc-shaped recesses 42 are respectively disposed on opposite sides of the two arms.

[0092] A plurality of arc-shaped recesses 42 are used to enclose a space for fixing the measuring part 5. For example, a notch groove 41 is formed between the two arms. The two arms are connected by bolts so that the distance between the two arms can be changed. When the distance between the two arms is reduced, the two opposite arc-shaped recesses 42 can clamp the measuring part 5 so that the measuring part 5 can be fixed to the mounting part 4.

[0093] The radii of the multiple arc-shaped recesses 42 may be different, so that the mounting portion 4 can be used to mount different types of measuring portions 5 .

[0094] The arcuate depressions 42 of the two arms can be arranged at intervals relative to each other. Alternatively, the arcuate depressions 42 of the two arms can also be connected to form a whole. For example, the circular end of the notch through groove 41 is two connected arcuate depressions 42.

[0095] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
