Description

Technical Field

[0001] This invention relates to an auxiliary locator, specifically an auxiliary locator for tire inspection, belonging to the technical field of tire inspection tools. Background Technology

[0002] Tire repair is a common operation in automotive tire maintenance. Typically, after removing the tire from the vehicle, a comprehensive inspection is required to determine the location of the puncture. This includes strictly judging whether the puncture is within the repairable tread area, whether its size is within a safe range, and whether the internal ply layers have been damaged due to driving with low pressure. Once the overall assessment is complete, repairs are performed using mushroom plugs or internal patches. However, current repair environments are often complex, with insufficient lighting inside the tire, making it difficult for operators to quickly and accurately locate the puncture, especially small punctures that are easily missed. Furthermore, the lack of auxiliary tools for locating punctures means that after a comprehensive inspection, additional time and effort are needed to reconfirm the puncture location, impacting repair efficiency.

[0003] Chinese patent titled "A Vehicle Maintenance Inspection Platform" (publication number CN222224095U) discloses an inspection platform technology. It uses positioning grooves to ensure the tires accurately enter their corresponding positions. The inflatable rubber pad, after inflation, completely adheres to the tire, providing stable support and effectively avoiding the risk of tire damage due to uneven force. This ensures the vehicle will not shake or slip during lifting and maintenance, preventing damage and providing a safe and reliable working environment for operators. However, although this inspection platform has a supplementary lighting structure, its overall structure is too large and the installation method is complex, making it unable to effectively cope with complex maintenance environments. Furthermore, it lacks the function of locating damaged areas. Therefore, an auxiliary locator for tire maintenance is proposed. Summary of the Invention

[0045] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figures 1-5 As shown, this embodiment of the invention provides an auxiliary positioning device for tire maintenance, including a clamping assembly 1 and a positioning mechanism 2. The clamping assembly 1 includes a lower clamping seat 101, an upper clamping seat 102 and a torsion spring 103.

[0048] The upper clamp 102 is hinged to the inner wall of the lower clamp 101. The torsion spring 103 is installed between the upper clamp 102 and the torsion spring 103. The positioning mechanism 2 is located on one side of the upper clamp 102 and is used to provide supplemental lighting for the tire and to locate the damaged area using laser. An adjustment mechanism 3 is installed between the positioning mechanism 2 and the upper clamp 102 to adjust the irradiation angle of the positioning mechanism 2.

[0049] The positioning mechanism 2 includes a lower support shell 201, a circuit board 204, a supplementary light 205, and a laser positioning light 206.

[0050] Among them, the circuit board 204 is installed in the middle of the inner side wall of the lower support shell 201, the supplementary light 205 is installed in the middle of the upper surface of the circuit board 204, and the laser positioning light 206 is installed on one side of the upper surface of the circuit board 204.

[0051] Among them, the adjustment mechanism 3 is an integrated unit.

[0052] The positioning mechanism 2 also includes an upper cover 202, a battery 203, and an operation panel 207;

[0053] The upper cover 202 is detachably installed on top of the lower support shell 201, the battery 203 is installed on the bottom of the inner side wall of the lower support shell 201, and the operation panel 207 is installed on one side of the lower support shell 201 and the upper cover 202.

[0054] The working auxiliary light 205 is used to illuminate the inside of the tire, and the working laser positioning light 206 is used to generate a laser beam to locate the damaged point. The installed battery 203 is used to power the circuit board 204, the auxiliary light 205 and the laser positioning light 206. The installed operation panel 207 is used to control the opening and closing of the auxiliary light 205 and the laser positioning light 206, and provides a charging interface for the battery 203.

[0055] like Figures 2-5 As shown, in one embodiment, two magnetic blocks 41 are symmetrically installed on the bottom of the lower clamp 101, a protective pad 42 is fixedly connected to one side of the bottom of the upper clamp 102, a slot 43 is integrally formed on one side of the upper surface of the upper clamp 102, and a card plate 44 is provided on one side of the lower support shell 201. The slot 43 and the card plate 44 are snapped together.

[0056] The auxiliary locator can be installed magnetically by using the magnetic block 41. By inserting the slot 43 into the card plate 44, the lower support shell 201 and the upper clamp 102 are limited, ensuring the overall stability of the auxiliary locator.

[0057] like Figures 2-3 As shown, in one embodiment, the adjustment mechanism 3 is an integral unit, including a first lower support block 301, a first upper support block 302, a first ball head rod 303, and a ball seat 304;

[0058] The first lower support block 301 is hinged to the inner wall of the upper clamping seat 102 on both sides. The first upper support block 302 is installed on the upper surface of the first lower support block 301. The first ball joint rod 303 is located on one side of the first upper support block 302. The first ball joint rod 303 and the first upper support block 302 are integrally formed. The ball seat 304 is detachably installed on the bottom of the inner wall of the lower support shell 201. One end of the first ball joint rod 303 is ball-jointed to the inner wall of the ball seat 304.

[0059] By using ball seat 304 to constrain the ball end of the first ball head rod 303 within the lower support shell 201, the ball seat 304 is moved when the lower support shell 201 is moved. The moving ball seat 304, in conjunction with the first ball head rod 303, drives the first upper support block 302 and the first lower support block 301 to rotate, thereby initially adjusting the overall angle of the positioning mechanism 2. Then, by rotating the lower support shell 201, the ball seat 304 is driven to rotate around the ball end of the first ball head rod 303, thereby further adjusting the overall angle of the positioning mechanism 2.

[0060] In operation, this invention works as follows: First, the installation method of the auxiliary positioner is determined according to the maintenance environment or actual needs. When clamping is required, simply press the upper clamp 102 to compress the torsion spring 103, then clamp the upper clamp 102 and lower clamp 101 at the designated position. The compressed torsion spring 103 provides a reverse thrust to the lower clamp 101 and upper clamp 102, ensuring a secure clamping effect. The protective pad 42 is used to protect the upper clamp 102 from the clamped object. When magnetic installation is required, simply move the lower clamp 101 to bring the magnet 41 into contact with the ferromagnetic material to complete the installation.

[0061] When it is necessary to illuminate the inside of the tire or locate the puncture point, press the operation panel 207 to activate the auxiliary light 205. The working auxiliary light 205 illuminates the inside of the tire. Then, press the operation panel 207 repeatedly to activate the laser positioning light 206. The working laser positioning light 206 generates a laser beam to locate the puncture point.

[0062] When it is necessary to adjust the lighting angle or laser irradiation angle, the lower support shell 201 is moved to drive the ball seat 304 to move. The moving ball seat 304, in conjunction with the first ball head rod 303, drives the first upper support block 302 and the first lower support block 301 to rotate, so as to make a preliminary adjustment to the overall angle of the positioning mechanism 2. Then, by rotating the lower support shell 201, the ball seat 304 is driven to rotate around the ball end of the first ball head rod 303, so as to further adjust the overall angle of the positioning mechanism 2, so as to control the lighting and positioning angles according to actual needs.

[0063] The slot 43 and the plate 44 are designed to limit the movement between the lower support shell 201 and the upper clamp 102 by inserting the slot 43 into the plate 44 after the auxiliary positioner has been used, thus ensuring the overall stability of the auxiliary positioner when stored.

[0064] Example 2

[0065] like Figures 1-10 As shown, this embodiment of the invention also provides an auxiliary positioning device for tire maintenance, including a clamping assembly 1 and a positioning mechanism 2. The clamping assembly 1 includes a lower clamping seat 101, an upper clamping seat 102 and a torsion spring 103.

[0066] The upper clamp 102 is hinged to the inner wall of the lower clamp 101. The torsion spring 103 is installed between the upper clamp 102 and the torsion spring 103. The positioning mechanism 2 is located on one side of the upper clamp 102 and is used to provide supplemental lighting for the tire and to locate the damaged area using laser. An adjustment mechanism 3 is installed between the positioning mechanism 2 and the upper clamp 102 to adjust the irradiation angle of the positioning mechanism 2.

[0067] The positioning mechanism 2 includes a lower support shell 201, a circuit board 204, a supplementary light 205, and a laser positioning light 206.

[0068] Among them, the circuit board 204 is installed in the middle of the inner side wall of the lower support shell 201, the supplementary light 205 is installed in the middle of the upper surface of the circuit board 204, and the laser positioning light 206 is installed on one side of the upper surface of the circuit board 204.

[0069] Among them, the adjustment mechanism 3 is a split type.

[0070] like Figures 7-10 As shown, in one embodiment, the adjustment mechanism 3 is a split type, including a second lower support block 311, a second upper support block 312, a second ball head rod 313, a card seat 314, a threaded sleeve 315, a first spring 316, a limiting ball 317, a ball groove 318, and a foolproof part 319.

[0071] The second lower support block 311 is hinged to the inner wall of the upper clamping seat 102 on both sides, the second upper support block 312 is installed on the upper surface of the second lower support block 311, one end of the second ball joint rod 313 is ball jointed between the second lower support block 311 and the second upper support block 312, the card seat 314 is detachably installed on the bottom of the inner wall of the lower support shell 201, the outer wall of the second ball joint rod 313 is slidably connected to the inner wall of the card seat 314, and the bottom of the lower support shell 201 is fixedly connected with a constraint band 45.

[0072] The outer wall of the threaded sleeve 315 is threaded to the top of the inner wall of the retainer 314. The limiting ball 317 is tactilely connected to the inner wall of the retainer 314. The first spring 316 is located between the threaded sleeve 315 and the limiting ball 317 to provide continuous thrust to the limiting ball 317. There are several ball grooves 318, which are symmetrically opened in pairs on the outer wall of the second ball head rod 313. The anti-fooling part 319 is symmetrically located on both sides of the outer wall of the second ball head rod 313. The outer wall of the anti-fooling part 319 is slidably connected to the inner wall of the retainer 314.

[0073] When it is necessary to adjust the lighting angle or laser irradiation angle, the lower support shell 201 is moved to drive the card holder 314 to move. The moving card holder 314, in conjunction with the second ball head rod 313, drives the second upper support block 312 and the second lower support block 311 to rotate, so as to make preliminary adjustment of the overall angle of the positioning mechanism 2. Then, by rotating the lower support shell 201, the card holder 314 is driven to rotate around the third ball head rod 323 as the axis, so that the ball end of the second ball head rod 313 rotates between the second lower support block 311 and the second upper support block 312, so as to further adjust the overall angle of the positioning mechanism 2. When it is necessary to adjust the overall extension length of the lower support shell 201, the lower support shell 201 can be moved to drive the card holder 314 to move. The moving card holder 314 uses pressure to drive the limiting ball 317 to roll outside the second ball head rod 313, so that the limiting ball 317 slides into the card holder 314 under pressure and drives the first spring 316 to compress. When the rolling limiting ball 317 slides into another ball groove 318 again, the compressed first spring 316 can be used to push the limiting ball 317 out of the card holder 314 into the ball groove 318 to increase the sense of jerk during extension adjustment and increase the resistance during adjustment, so as to ensure the stability of the auxiliary positioner during use.

[0074] The lower support shell 201 can be moved to allow the card holder 314 to slide completely off the second ball joint rod 313, thus separating the positioning mechanism 2 from the clamping assembly 1 for independent use of the positioning mechanism 2. A constraint strap 45 is provided to restrain the positioning mechanism 2 onto the fingers of maintenance personnel when used alone, facilitating its movement and illumination operation. A foolproof part 319 is provided to position the second ball joint rod 313 and the card holder 314, ensuring that the card holder 314 can only slide along the axial direction of the second ball joint rod 313. Furthermore, ball grooves 318 are formed on both sides of the outer wall of the second ball joint rod 313, so that when the lower support shell 201 moves to connect the card holder 314 to the second ball joint rod 313, it is not restricted by the front or back orientation; it is only necessary to ensure that the foolproof part 319 can smoothly slide into the card holder 314.

[0075] Example 3

[0076] like Figures 1-15 As shown, this embodiment of the invention also provides an auxiliary positioning device for tire maintenance, including a clamping assembly 1 and a positioning mechanism 2. The clamping assembly 1 includes a lower clamping seat 101, an upper clamping seat 102 and a torsion spring 103.

[0077] The upper clamp 102 is hinged to the inner wall of the lower clamp 101. The torsion spring 103 is installed between the upper clamp 102 and the torsion spring 103. The positioning mechanism 2 is located on one side of the upper clamp 102 and is used to provide supplemental lighting for the tire and to locate the damaged area using laser. An adjustment mechanism 3 is installed between the positioning mechanism 2 and the upper clamp 102 to adjust the irradiation angle of the positioning mechanism 2.

[0078] The positioning mechanism 2 includes a lower support shell 201, a circuit board 204, a supplementary light 205, and a laser positioning light 206.

[0079] Among them, the circuit board 204 is installed in the middle of the inner side wall of the lower support shell 201, the supplementary light 205 is installed in the middle of the upper surface of the circuit board 204, and the laser positioning light 206 is installed on one side of the upper surface of the circuit board 204.

[0080] Among them, the adjustment mechanism 3 is a split type.

[0081] like Figures 12-15 As shown, in one embodiment, the adjustment mechanism 3 is a split type, including a third lower support block 321, a third upper support block 322, a third ball head rod 323, a limiting seat 324, a pressure frame 325, a limiting block 326, an upper sleeve 327, a lower sleeve 328, a second spring 329, and a limiting groove 320.

[0082] The third lower support block 321 is hinged to the inner wall of the upper clamping seat 102 on both sides, the third upper support block 322 is installed on the upper surface of the third lower support block 321, one end of the third ball joint rod 323 is ball-jointed between the third lower support block 321 and the third upper support block 322, the limiting seat 324 is detachably installed on the bottom of the inner wall of the lower support shell 201, the pressure frame 325 is slidably connected to the inner wall of the limiting seat 324, and the bottom of the lower support shell 201 is fixedly connected with a constraint band 45.

[0083] The bottom of the pressure frame 325 passes through the limiting seat 324 and is fixedly connected to the limiting block 326. The outer side wall of the limiting block 326 is slidably connected to the inner side wall of the limiting seat 324. There are several limiting grooves 320, which are symmetrically opened in pairs on the outer side wall of the third ball head rod 323. The top of the limiting block 326 is inserted into the inner side wall of the limiting groove 320. The top of the upper sleeve 327 is fixedly connected to the middle of the lower surface of the limiting block 326. The bottom of the lower sleeve 328 is fixedly connected to the bottom of the inner side wall of the lower support shell 201. The outer side wall of the upper sleeve 327 is slidably connected to the inner side wall of the lower sleeve 328. The second spring 329 is located in the upper sleeve 327 and the second spring 329. The top of the spring abuts against the bottom of the limiting block 326, and the bottom of the spring abuts against the bottom of the inner side wall of the lower support shell 201.

[0084] When it is necessary to adjust the lighting angle or laser irradiation angle, the lower support shell 201 is moved to drive the limiting seat 324 to move. The moving limiting seat 324, in conjunction with the third ball head rod 323, drives the third upper support block 322 and the third lower support block 321 to rotate, so as to make preliminary adjustment of the overall angle of the positioning mechanism 2. Then, by rotating the lower support shell 201, the limiting seat 324 is driven to rotate around the third ball head rod 323 as the axis, so that the ball end of the third ball head rod 323 rotates between the third lower support block 321 and the third upper support block 322, so as to further adjust the overall angle of the positioning mechanism 2. When it is necessary to adjust the overall extension length of the lower support shell 201, pressing the pressure frame 325 drives the limiting block 326 to move. The moving limiting block 326 slides out from the limiting groove 320, releasing the limitation between the limiting seat 324 and the third ball joint rod 323. This allows the lower support shell 201 to move according to actual needs, driving the limiting seat 324 to move axially along the third ball joint rod 323, thus adjusting the overall extension length of the lower support shell 201. At the same time, the moving limiting block 326 drives the upper sleeve 327 and the second spring 329 to move. The moving upper sleeve 327 slides within the lower sleeve 328, guiding the movement of the limiting block 326. The moving second spring 329 is compressed so that when the pressure frame 325 is released, the compressed second spring 329 can push the pressure frame 325 back to its original position and drive the limiting block 326 to insert into the limiting groove 320, thus re-limiting the limiting seat 324 and the third ball joint rod 323.

[0085] Similar to Embodiment 2, the positioning mechanism 2 in this embodiment can also be detached and used separately. The difference is that the locking between the limit seat 324 and the third ball joint rod 323 is controlled by manual pressing, which makes the stability of the auxiliary positioner higher.

[0086] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
