Description

Technical Field

[0001] This utility model relates to the field of sensors, specifically to a fast positioning and mounting RFID sensor for go-karts. Background Technology

[0002] With the increasing sophistication of go-karting competition and training scenarios, RFID sensors are being used more and more extensively in go-karting. They are primarily used to collect real-time data such as go-kart speed and trajectory, providing support for race analysis, vehicle calibration, and safety monitoring. RFID sensors need to be installed on the go-kart body and must meet the requirements of "quick installation and removal to adapt to different testing needs, and stable mounting to cope with the high-frequency vibrations of the go-kart."

[0003] 1. Currently, most traditional fixing devices on the market use integral clamps or welded bracket structures. During installation, multiple bolts need to be tightened one by one, and it is not possible to quickly position and snap them onto the sensor bracket. This results in long installation and position adjustment times for the sensor, making it difficult to meet the "quick assembly and disassembly" requirements in high-frequency debugging scenarios.

[0004] 2. The traditional devices currently used in the market lack targeted anti-vibration and precise positioning designs. Either the snap-fit ​​structure lacks elastic buffering, causing the sensor to easily loosen and shift during vibration, or the poor compatibility between the bracket and the sensor makes it impossible to achieve stable fixation of the sensor, thus affecting the accuracy of data acquisition.

[0005] Therefore, a fast positioning and installation RFID sensor fixing structure for go-karts is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a fast positioning and installation RFID sensor fixing structure for go-karts. It has the advantages of fast positioning and installation and strong fixing stability. It solves the problems of traditional fixing devices currently used in the market, which mostly adopt integral clamps or welded bracket structures. During installation, multiple bolts need to be tightened one by one, and it is impossible to quickly achieve positioning and snap-fit ​​with the sensor bracket. This results in long sensor installation and position adjustment time, which is difficult to meet the "quick disassembly and assembly" requirements in high-frequency debugging scenarios.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fast positioning and installation RFID sensor fixing structure for go-karts, including a clamp seat. The clamp seat is composed of two symmetrical arc-shaped annular clamps joined together. The annular clamps are made of metal, and both ends of the two annular clamps are provided with corresponding concave threaded grooves that penetrate the thickness direction of the annular clamps. One end of the clamp seat has an integrally formed outwardly extending plate-shaped locking ear, which is made of the same metal as the annular clamp. Both ends of the locking ear have concave locking grooves on their sidewalls, which are set along the height direction of the locking ear. The locking ear is quickly connected by locking and engaging with the locking grooves at both ends. The positioning and installation device is a block-shaped structure made of plastic. It is embedded in the installation cavity inside the sensor fixing bracket base, and the outer wall of the quick positioning and installation device is in contact with the inner wall of the installation cavity. The sensor fixing bracket base is a rectangular block structure made of plastic. Its top end face is fixedly connected to the bottom end face of the sensor bracket by bolts. The sensor bracket is made of metal. The inner walls of the left and right sides of the sensor bracket are provided with strip-shaped tracks extending along their length. The tracks and the sensor bracket are integrally formed. Block-shaped locking blocks are slidably arranged on the tracks. The locking blocks are made of plastic and their side walls are in contact with the inner wall of the tracks.

[0008] The quick positioning and installation device includes a vertically arranged columnar button rod made of plastic, with its top end extending beyond the top surface of the quick positioning and installation device. A ring-shaped groove is provided on the circumferential side wall of the upper half of the button rod, encircling the circumference of the button rod. A vertical return spring, made of metal, is fitted below the button rod, with its top end abutting against the bottom surface of the button rod and its bottom end abutting against the bottom inner wall of the quick positioning and installation device's mounting cavity. A wedge-shaped locking block, made of plastic, is provided on one side of the button rod, with its side facing the button rod connected to a transverse tightening spring, made of metal, and its other end abutting against the side wall of the button rod. The side of the wedge-shaped locking block away from the transverse tightening spring extends beyond the side wall of the quick positioning and installation device, fitting and engaging with the locking groove of the locking lug. The outer wall of the wedge-shaped locking block fits against the inner wall of the locking groove.

[0009] Furthermore, the card block is generally rectangular in shape, with a concave groove structure on one end face. This groove structure is adapted to the track and used to slide on the track. The inner wall of the groove structure of the card block has a strip-shaped protrusion, which is adapted to the outer protrusion structure of the track.

[0010] Furthermore, the card block has a recessed sensor mounting groove on the other end face away from the groove structure.

[0011] Furthermore, the top of the button lever is provided with a circular pressing head, the diameter of which is larger than the diameter of the button lever body.

[0012] Furthermore, the two annular clamps of the clamp seat are fitted with fastening bolts in their threaded grooves to secure the two annular clamps together.

[0013] Furthermore, the end face of the wedge-shaped block away from the button lever is an inclined surface, which gradually slopes towards the button lever from the top to the bottom of the wedge-shaped block.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The RFID sensor fixing structure for rapid positioning and installation in this go-kart utilizes a collaborative design of interlocking clamps and a rapid positioning and installation device. Two arc-shaped ring clamps can quickly encircle the go-kart frame, and threaded grooves, combined with fastening bolts, achieve initial fixation. The locking lugs and the slots of the rapid positioning and installation device, along with the wedge-shaped locking block adaptation structure, allow for precise locking without tools. The push-to-unlock design of the button lever further simplifies the disassembly process. Simultaneously, the strip track inside the sensor bracket, in conjunction with the sliding block, allows for quick adjustment of the sensor's installation position, significantly shortening disassembly, assembly, and debugging time, thus meeting the core requirements of rapid positioning and installation.

[0016] 2. This go-kart uses a quick-positioning RFID sensor fixing structure. Vertical and horizontal springs within the quick-positioning device buffer the vibration and displacement of the button lever and wedge-shaped locking block, ensuring a tight fit between the wedge-shaped locking block and the slot. The strip-shaped protrusions on the inner wall of the locking block's groove cooperate with the outer protruding structure of the track to prevent rotational displacement during sliding. Simultaneously, the metal ring clamp and sensor bracket ensure structural strength, while the plastic quick-positioning device and locking block achieve lightweight design, balancing strength and weight requirements. This effectively resists the impact of complex working conditions on the fixing structure, ensuring long-term stable sensor operation and reducing data acquisition deviations caused by fixing issues.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This embodiment of an RFID sensor fixing structure for quick positioning and installation on a go-kart includes a clamp seat 1, which is composed of two symmetrical arc-shaped annular clamps. The annular clamps are made of metal, and both ends of the two annular clamps have corresponding concave threaded grooves 2, which penetrate the thickness direction of the annular clamps. One end of the clamp seat 1 has an integrally formed outwardly extending plate-shaped locking ear 3, which is made of the same metal as the annular clamp. Both ends of the locking ear 3 have concave locking grooves 4, which are set along the height direction of the locking ear 3. The locking ear 3 is engaged with the quick positioning and installation device (5) through the locking grooves 4 at both ends. The quick positioning and installation device 5 is a block structure made of plastic and is embedded in the installation cavity inside the sensor fixing bracket base 6. The outer wall of the quick positioning and installation device 5 is in contact with the inner wall of the installation cavity. The sensor fixing bracket base 6 is a rectangular block structure made of plastic. Its top end face is fixed to the bottom end face of the sensor bracket 7 by bolts. The sensor bracket 7 is made of metal. The inner walls of the left and right sides of the sensor bracket 7 are provided with strip-shaped tracks 8 extending along its length. The tracks 8 and the sensor bracket 7 are integrally formed. Block-shaped locking blocks 9 are slidably set on the tracks 8. The locking blocks 9 are made of plastic and their side walls are in contact with the inner walls of the tracks 8.

[0025] The quick-positioning installation device 5 includes a vertically arranged columnar button rod 501. The button rod 501 is made of plastic, and its top end extends out of the top end face of the quick-positioning installation device 5. A ring groove is provided on the circumferential side wall of the upper half of the button rod 501. The groove is arranged around the circumference of the button rod 501. A vertical return spring 502 is sleeved below the button rod 501. The vertical return spring 502 is made of metal, and its top end abuts against the bottom end face of the button rod 501, while its bottom end is in contact with the mounting cavity of the quick-positioning installation device 5. The bottom inner wall abuts against the button rod 501. A wedge-shaped locking block 503 is provided on one side of the button rod 501. The wedge-shaped locking block 503 is made of plastic. Its end face facing the button rod 501 is connected to a transverse clamping spring 504. The transverse clamping spring 504 is made of metal. Its other end abuts against the side wall of the button rod 501. The side of the wedge-shaped locking block 503 away from the transverse clamping spring 504 extends out of the side wall of the quick positioning installation device 5 and is adapted to and engaged with the slot 4 of the locking ear seat 3. The outer wall of the wedge-shaped locking block 503 fits against the inner wall of the slot 4.

[0026] The locking block 9 has a regular rectangular shape with a recessed groove on one end face. The size and shape of this groove perfectly match the track 8, allowing it to fit into the track 8 and slide smoothly along its length. On the inner wall of the groove, a strip-shaped protrusion is integrally formed. This protrusion matches the pre-designed protrusion on the outer wall of the track 8, restricting the rotation of the locking block 9 on the track 8. This locking block 9 structure with a groove and a strip-shaped protrusion ensures the flexibility of sliding along the track 8, meeting the adjustment needs of different sensor installation positions. Furthermore, the cooperation between the strip-shaped protrusion and the protrusion of the track 8 prevents the locking block 9 from rotating, ensuring the sensor's stable position after installation and preventing angular displacement due to go-kart vibration.

[0027] On the opposite end face of the card block 9, away from the groove structure, there is a recessed sensor mounting groove. The depth and area of ​​this groove are adapted to the corner dimensions of the RFID sensor, allowing one corner of the sensor to be stably embedded within it. The design of the card block 9 with the sensor mounting groove provides precise positioning and limiting of the sensor, preventing displacement during installation. Simultaneously, the groove structure disperses external impacts on the sensor, reducing the impact of go-kart bumps on the sensor, protecting the sensor housing from damage by compression, and extending the sensor's lifespan.

[0028] The top of the button lever 501 is integrally injection-molded with a circular pressing head. The diameter of this circular pressing head is significantly larger than the diameter of the main body of the button lever 501, and the surface of the pressing head has a frosted finish. This structure, with the circular pressing head at the top of the button lever 501, increases the contact area between the hand and the button lever 501, making it easier for operators to quickly locate the pressing position and apply force. The frosted finish also improves the anti-slip effect during pressing, preventing hand slippage and delaying the unlocking action, further enhancing the ease of assembly and disassembly of the device.

[0029] On the two annular clamps of clamp seat 1, corresponding threaded grooves 2 are provided for the installation of fastening bolts. The thread specifications of the fastening bolts are perfectly matched with the threaded grooves 2. After tightening, the two annular clamps can be tightly joined and fixed to the go-kart frame. The structure of threaded grooves 2 and fastening bolts can firmly fix the two annular clamps through the axial force of the bolts, enhancing the stability of the connection between clamp seat 1 and the frame, preventing clamp seat 1 from loosening and falling off due to high-frequency vibration of the go-kart. At the same time, the bolt connection method facilitates later disassembly and maintenance, and the tightness of the clamps can be adjusted according to different diameter frames.

[0030] The wedge-shaped locking block 503 has an inclined surface on the side away from the button lever 501. This inclined surface starts from the top of the wedge-shaped locking block 503 and gradually slopes towards the button lever 501 as it extends towards the bottom, forming a smooth slope transition. The inclined surface of the wedge-shaped locking block 503 serves as a guide when the quick-positioning installation device 5 mates with the locking lug 3, allowing the wedge-shaped locking block 503 to slide more smoothly into the locking groove 4 and reducing jamming during mating. Simultaneously, the inclined surface design increases the contact area between the wedge-shaped locking block 503 and the locking groove 4, improving the locking stability and preventing the device from loosening due to detachment.

[0031] In summary, the two annular clamps of the RFID sensor fixing structure clamp seat 1 fit against the go-kart frame, and the two annular clamps are spliced ​​and fixed by the fastening bolts in the threaded groove 2 to complete the basic fixing. Subsequently, the quick positioning and installation device 5 is adapted to the groove 4 of the locking ear seat 3 through the wedge-shaped locking block 503 to connect the sensor fixing bracket base 6 and the clamp seat 1. If disassembly is required, pressing the round pressing head at the top of the button rod 501 can drive the wedge-shaped locking block 503 to compress the transverse tightening spring, so that the wedge-shaped locking block 503 is disengaged from the groove 4. Finally, the RFID sensor is embedded in the sensor mounting groove of the locking block 9, and the position is adjusted by sliding along the track 8 through the groove structure on one side of the locking block 9. At the same time, the strip-shaped protrusion on the inner wall of the groove structure of the locking block 9 fits with the outer protrusion structure of the track 8, restricting the rotation of the locking block 9, and completing the positioning and installation of the sensor.

[0032] Furthermore, the groove and strip protrusion of the locking block 9 combine sliding flexibility and positional stability, preventing the sensor from shifting due to vibration. The sensor mounting groove can disperse external impact, protecting the sensor and extending its service life. The circular pressing head of the button rod 501 increases the contact area and is anti-slip, improving the ease of disassembly and assembly. The threaded groove 2 of the clamp seat 1 cooperates with the fastening bolt to enhance the stability of the connection with the frame and facilitate maintenance. The inclined surface of the wedge-shaped locking block 503 achieves smooth docking and firm locking, reducing the risk of jamming and loosening. The overall structure meets the needs of rapid sensor positioning, installation and stable operation in go-kart scenarios.
