Technical Field

[0001] This utility model relates to the field of vehicle testing technology, and in particular to a mounting mechanism for installing vehicle speed measuring equipment. Background Technology

[0002] Wheel speed is a crucial parameter in automotive road testing and an essential parameter for the development of many automotive driver assistance technologies. Current methods for acquiring wheel speed primarily include simple measurements using Hall effect, electromagnetic, magneto-electric, and photoelectric sensors. For vehicles equipped with anti-lock braking systems (ABS) or electronic stability systems (ESS), the vehicle speed signal can be obtained from the vehicle's main control unit. However, the accuracy of such a signal is far from sufficient for experiments requiring instantaneous speed measurements. To obtain higher wheel speed measurement accuracy, encoders are installed at the wheel hubs for speed measurement.

[0003] The installation methods for vehicle encoders are mostly very complicated. The flexible coupling is connected to the vehicle's transmission output shaft, and the housing is connected to the vehicle body. When connecting the encoder's housing to the vehicle body, the installation structure is relatively complicated and not convenient for disassembly and installation.

[0004] Therefore, the mounting structure of encoders in the existing technology needs to be improved to facilitate installation and disassembly. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an installation mechanism for installing vehicle speed measuring equipment, which improves the installation structure of the speed measuring equipment, facilitates the installation and disassembly of the speed measuring device, and has a simple overall installation method that is easy for users to use.

[0006] The present invention discloses an installation mechanism for mounting vehicle speed measuring equipment, comprising a fixed plate and a locking mechanism for fixing the fixed plate to a vehicle wheel hub. The locking mechanism includes a locking plate and a plurality of locking members distributed along the circumferential direction and installed on the vehicle wheel hub. The locking members pass axially through the fixed plate, thereby enabling the fixed plate to engage with the vehicle wheel hub in the circumferential direction. The locking plate is installed on the locking members and presses the fixed plate axially, limiting the fixed plate axially within the locking members. The fixed plate is provided with a mounting position for mounting the vehicle speed measuring equipment.

The locking seat is fixed to the vehicle wheel hub, and the locking rod is connected to the locking seat and passes through the fixing plate and the locking plate, pressing the fixing plate against the locking seat through the locking plate.

[0009] Furthermore, the outer end of the locking rod is provided with a crossbar, and the locking disc is provided with an end face cam structure corresponding to the crossbar. The rotation of the locking disc can be driven to make the crossbar and the cam surface of the end face cam structure gradually press together to form a locking of the locking disc, and make the fixed disc press against the locking seat.

[0010] Furthermore, it also includes a locking drive mechanism, which is mounted on the fixed plate and has a power output end, which is used to drive the locking plate to rotate.

[0011] Furthermore, the locking drive mechanism includes a drive screw disposed on the fixed disk along the tangential direction of the circumference of the fixed disk and an adjusting nut disposed on the locking disk and cooperating with the drive screw. The drive screw can be driven to rotate, thereby driving the locking disk to rotate through the adjusting nut.

[0012] Furthermore, the locking drive mechanism also includes mounting base I and mounting base II. Mounting base I is disposed on the fixed plate, and mounting base II is disposed on the locking plate. There are two adjusting nuts, which are disposed one-to-one on mounting base I and mounting base II.

[0013] Furthermore, the edge of the locking disc bends and extends towards the fixed disc to form a connecting ring protrusion, the fixed disc is located inside the connecting ring protrusion, the connecting ring protrusion is provided with a clearance opening, the mounting seat I is disposed on the edge of the fixed disc corresponding to the clearance opening, and the mounting seat II is disposed at the clearance opening.

[0014] Furthermore, the locking mechanism also includes a rubber pad, which is disposed at the end of the locking rod that connects to the locking seat and is located inside the locking seat.

[0015] Furthermore, the fixed plate has a plurality of radial grooves that cooperate with the locking rod, and the locking plate has a plurality of circumferential grooves that cooperate with the locking rod, and the circumferential grooves are provided on the end face cam structure.

[0026] like Figure 1-6 As shown: The mounting mechanism for installing a vehicle speed measuring device in this embodiment includes a fixed plate 4 and a locking mechanism for fixing the fixed plate 4 to the vehicle wheel hub. The locking mechanism includes a locking plate 2 and a plurality of locking members 5 distributed along the circumferential direction and installed on the vehicle wheel hub 3. The locking members 5 pass through the fixed plate 4 axially and make the fixed plate 4 drively cooperate with the vehicle wheel hub 3 in the circumferential direction. The locking plate 2 is installed on the locking member 5 and presses the fixed plate 4 axially and limits the fixed plate 4 axially to the locking member 5. The fixed plate 4 is provided with a mounting position 402 for installing the vehicle speed measuring device 1. The number of locking components 5 is generally consistent with the number of wheel hub bolts 301. The speed measuring device 1 is generally an encoder. The encoder is generally installed on the mounting position 402 of the fixed plate 4 through a coupling. After being installed on the mounting position 402, it is connected to the car body through a connecting rod. The connection method between the encoder and the mounting position 402 and the car body is an application of existing technology and will not be described in detail here. During assembly, the fixed plate 4 is installed on the car wheel hub 3 through the locking components 5 and axially limited by the locking plate 2. Compared with the existing technology, it is easier for users to install and remove the fixed plate 4.

[0027] In this embodiment, the mounting position 402 is a mounting boss located in the middle of the fixed plate 4, and the locking plate 2 has a clearance through hole for the mounting boss to pass through. The mounting boss is an annular protrusion, and the locking plate 2 has an annular structure, so that the locking plate 2 can pass through the mounting boss and press against the surface of the fixed plate 4.

[0028] In this embodiment, the locking component 5 includes a locking rod 503 and a locking seat 501. The locking seat 501 is fixed to the vehicle wheel hub 3. The locking rod 503 is connected to the locking seat 501 and passes through the fixing plate 4 and the locking plate 2, and presses the fixing plate 4 onto the locking seat 501 through the locking plate 2. The locking seat 501 is a hollow columnar structure with openings at both ends. The end of the locking seat 501 connected to the vehicle wheel hub 3 has an internal thread and is connected to the vehicle wheel hub bolt 301. The locking rod 503 fixes the plate 4 and the locking plate 2 in sequence and presses the fixing seat onto the locking seat 501 through the locking plate 2. That is, the locking seat 501 is located on the inner side of the fixing plate 4 (the side closer to the vehicle wheel hub 3).

[0029] In this embodiment, the outer end of the locking rod 503 is provided with a crossbar 502, and the locking disc 2 is provided with an end face cam structure 201 corresponding to the crossbar 502. The rotation of the locking disc 2 can be driven so that the crossbar 502 and the cam surface of the end face cam structure 201 are gradually pressed together to form a locking of the locking disc 2, and so that the fixed disc 4 is pressed against the locking seat 501.

[0030] Specifically, the locking seat 501, locking rod 503, and crossbar 502 form a T-shaped structure. The locking rod 503 and crossbar 502 can be integrally formed or separate structures, such as the crossbar 502 being welded to the locking rod 503 or other connection methods, thus facilitating assembly. Further details are omitted here. The end-face cam structure 201 is located on the side of the locking disc 2 away from the fixed disc 4, such as... Figure 6 As shown, the end face cam structure 201 consists of several ramp structures on the locking disc 2. The number of ramp structures is consistent with the number of locking parts 5. When the assembly is completed, the crossbar 502 presses against the surface of the ramp structure. When the locking disc 2 is driven to rotate, the crossbar 502 can rise along the ramp surface of the end face cam structure 201 (i.e., gradually press against the cam surface of the end face cam structure 201), thereby achieving the locking and fixing of the fixed disc 4. The overall structure is simple, easy to disassemble, and convenient for user operation.

[0031] In this embodiment, a locking drive mechanism 6 is also included. The locking drive mechanism 6 is mounted on the fixed disk 4 and has a power output end, which is used to drive the locking disk 2 to rotate. The power output end can be driven by a motor or by the cooperation of a screw and a nut.

[0032] In this embodiment, the locking drive mechanism 6 includes a drive screw 602 disposed tangentially to the circumference of the fixed disk 4 and an adjusting nut 603 disposed on the locking disk 2 and cooperating with the drive screw 602. The drive screw 602 can be driven to rotate, thereby causing the locking disk 2 to rotate via the adjusting nut 603. In use, the drive screw 602 is manually rotated, thereby causing the locking disk 2 to rotate via the adjusting nut 603. The overall adjustment method is simple and reliable.

[0033] In this embodiment, the locking drive mechanism 6 further includes mounting base I 604 and mounting base II 601. Mounting base I 604 is disposed on the fixed plate 4, and mounting base II 601 is disposed on the locking plate 2. There are two adjusting nuts 603, which are disposed one-to-one on mounting base I 604 and mounting base II 601.

[0034] Specifically, such as Figure 5 and Figure 6 As described above, mounting base I 604 and mounting base II 601 are respectively disposed on the circumferential edges of the fixed plate 4 and the locking plate 2. Both mounting base I 604 and mounting base II 601 are U-shaped open slot structures, generally composed of three plate-shaped structures welded together. Adjusting nuts 603 are respectively installed on mounting base I 604 and mounting base II 601 through support rods. Of course, both mounting base I 604 and mounting base II 601 are provided with through holes for the support rods to pass through. One end of the drive screw 602 passes through the two adjusting nuts 603 in sequence and is threadedly engaged with the adjusting nuts 603, thereby realizing the rotation and locking of the locking plate 2.

[0035] In this embodiment, the edge of the locking disc 2 is bent and extended towards the fixing disc 4 to form a connecting ring protrusion. The fixing disc 4 is located inside the connecting ring protrusion. The connecting ring protrusion is provided with a clearance opening 203. The mounting base I 604 is disposed on the edge of the fixing disc 4 corresponding to the position of the clearance opening 203. The mounting base II 601 is disposed at the clearance opening 203. Figure 6 As shown, the connecting ring has a relief opening 203. When the locking disc 2 is installed on the fixed disc 4, the inner side wall of the connecting ring protrudes and contacts the outer circumference of the fixed disc 4. The mounting seat I 604 is located at the relief opening 203. The mounting seat II 601 is fixedly connected to one side wall of the relief opening 203. By setting the relief opening 203, it is convenient to install the mounting seat I 604 and the mounting seat II 601.

[0036] In this embodiment, the locking mechanism further includes a rubber pad 504, which is disposed at the end where the locking rod 503 connects to the locking seat 501 and is located inside the locking seat 501. The rubber pad 504 has a certain thickness. By providing the rubber pad 504, the locking rod 503 can be prevented from coming out of the locking seat 501, and it can also play a certain buffering role.

[0037] In this embodiment, the fixed disk 4 is provided with a plurality of strip grooves 401 along the radial direction that cooperate with the locking rod 503, and the locking disk 2 is provided with a plurality of arc grooves 202 along the circumferential direction that cooperate with the locking rod 503. The arc grooves 202 are disposed on the end face cam structure 201.

[0038] Specifically, such as Figure 5 As shown, the fixed disk 4 has several radially arranged slots 401, such as... Figure 6 The locking disc 2 has several arc-shaped grooves 202 arranged along the circumferential direction corresponding to the position of the strip groove 401, so that the locking rod 503 can pass through the strip groove 401 and the arc-shaped groove 202 and extend out of the arc-shaped groove 202, so that the crossbar 502 is placed horizontally on the inclined surface of the end face cam structure 201. When the locking disc 2 rotates, the crossbar 502 rises along the inclined surface of the end face cam structure 201 and abuts against the inclined surface of the end face cam structure 201, thereby realizing the locking and fixing of the fixing disc 4.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
