Description

Technical Field

[0001] This utility model relates to the field of automotive sensor fixture technology, and in particular to a fixture for automotive sensors. Background Technology

[0002] Automotive sensors are input devices for a car's computer system. They convert various operating conditions of the vehicle, such as vehicle speed, temperature of various media, and engine operating conditions, into electrical signals and transmit them to the computer so that the engine can operate at its optimal state. Automotive sensors need to be fixed in specific locations using clamps during use.

[0003] Chinese patent CN212255377U discloses a clamp for an automotive speed sensor, including a mounting component, a connecting plate, a fixed clamping plate, a movable clamping plate, and an adjusting screw. A mounting component is fixedly mounted on one side of the connecting plate, and the mounting component has an assembly hole. A fixed clamping plate and a movable clamping plate are respectively located on the side of the connecting plate away from the mounting component. The fixed clamping plate is fixedly mounted on the connecting plate. A sliding mechanism is provided between the movable clamping plate and the connecting plate. Under the action of the sliding mechanism, the movable clamping plate can move towards or away from the fixed clamping plate. A slot for placing the speed sensor is provided on the opposite side of both the fixed clamping plate and the movable clamping plate. A first threaded hole is provided on the upper and lower parts of the fixed clamping plate on the side away from the connecting plate, and a second threaded hole is provided on the upper and lower parts of the movable clamping plate on the side away from the connecting plate. The adjusting screw passes through the first threaded hole and the second threaded hole respectively to fix the fixed clamping plate and the movable clamping plate together.

[0004] The aforementioned clamp uses an adjusting screw and a fixing nut to fix the movable clamping plate and the fixed clamping plate together. This fixing method of screw and nut is prone to causing the screw to rotate under long-term vibration, causing the movable clamping plate to detach from the fixed clamping plate and affecting the stability of the clamp. In addition, automotive sensors are mostly cylindrical or rectangular in shape, and it is necessary to replace them with corresponding clamping plates to adapt to the shape of the sensors to ensure the clamping effect. However, most of them are currently fixed with screws, and tools are needed to remove the screws when replacing the clamping plates, which is quite troublesome. Utility Model Content

[0005] The main purpose of this invention is to provide a clamp for automotive sensors that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clamp for automotive sensors, comprising a connecting shell, a mounting plate fixedly connected to the top wall of the connecting shell, the mounting plate having assembly holes, a bidirectional screw rotatably disposed between the inner walls of both sides of the connecting shell, two symmetrically distributed moving blocks slidingly disposed inside the connecting shell, the moving blocks being threaded onto the bidirectional screw, an adapter block fixedly connected to the bottom wall of the moving blocks, the bottom wall of the adapter block extending out of the connecting shell and fixedly connected to a connector, a clamping plate being detachably connected to the connector via a quick-connect mechanism, and an adjustment mechanism being provided on one outer wall of the connecting shell.

[0007] As a further description of the above technical solution, the adjustment mechanism includes a receiving groove, a rotating shaft, a follower column, a sliding plate, a connecting rod, a knob, meshing teeth, a return spring, and a limiting toothed ring. A receiving groove is provided on one outer wall of the connecting shell. One end of the bidirectional screw is fixedly connected to a rotating shaft. The rotating shaft extends into the receiving groove and is fixedly connected to a follower column. A sliding plate is slidably mounted on the follower column. Two symmetrically distributed connecting rods are fixedly connected to one side wall of the sliding plate. A knob is fixedly connected to the other end of the connecting rod. A return spring is fixedly connected to one inner wall of the follower column. The other end of the return spring is fixedly connected to the sliding plate. A limiting toothed ring is fixedly connected to the groove wall of the receiving groove. A plurality of meshing teeth that cooperate with the limiting toothed ring are provided around the knob.

[0008] As a further description of the above technical solution, the quick connection mechanism includes a connecting groove, a recess, a locking block, a pull rod, and a clamping spring. The bottom wall of the connector has a connecting groove, and the front and rear side walls of the connecting groove have recesses. The locking block is slidably disposed in the recess. The pull rod is fixedly connected to the side wall of the locking block away from the connecting groove. The other end of the pull rod extends out of the connector. The clamping spring is sleeved on the pull rod. One end of the clamping spring is fixedly connected to the side wall of the recess away from the connecting groove, and the other end is fixedly connected to the locking block.

[0009] As a further description of the above technical solution, a connecting block is fixedly connected to the top wall of the clamping plate.

[0011] As a further description of the above technical solution, the clamp has a slot, and a rubber pad is provided in the slot.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This fixture uses a bidirectional screw to control the movement of the two clamping plates. With the adjustment mechanism, the knob can be retracted into the receiving groove when the position of the clamping plates does not need to be changed, thus preventing accidental activation of the knob and causing the bidirectional screw to rotate, which would affect the position of the two clamping plates. At the same time, the limiting gear ring in the receiving groove can limit the knob to prevent it from rotating when not in operation, thereby improving stability.

[0014] 2. The quick-connect mechanism allows for tool-free replacement of the clamps, making the replacement process convenient, fast, and more practical. Attached Figure Description

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-8 This utility model provides a clamp for automotive sensors, including a connecting shell 1. A mounting plate 2 is fixedly connected to the top wall of the connecting shell 1. The mounting plate 2 has an assembly hole 21. A bidirectional screw 3 is rotatably provided between the inner walls of both sides of the connecting shell 1. Two symmetrically distributed moving blocks 4 are slidably provided inside the connecting shell 1. The moving blocks 4 are threaded onto the bidirectional screw 3. An adapter block 41 is fixedly connected to the bottom wall of the moving blocks 4. The bottom wall of the adapter block 41 extends out of the connecting shell 1 and is fixedly connected to a connector 5. A clamping plate 6 is detachably connected to the connector 5 through a quick-connect mechanism 8. When the bidirectional screw 3 rotates, the two moving blocks 4 can drive the clamping plate 6 to move closer to each other through the adapter block 41, so that the two clamping plates 6 can clamp and fix the automotive sensor. An adjustment mechanism 7 is provided on one outer wall of the connecting shell 1.

[0028] Specifically, such as Figures 3 to 5As shown, a clamp for an automotive sensor includes an adjustment mechanism 7 comprising a receiving groove 71, a rotating shaft 72, a follower post 73, a sliding plate 74, a connecting rod 75, a knob 76, a meshing gear 761, a return spring 77, and a limiting gear ring 78. The receiving groove 71 is formed on one outer wall of the connecting housing 1. One end of the bidirectional screw 3 is fixedly connected to the rotating shaft 72, which extends into the receiving groove 71 and is fixedly connected to the follower post 73. The sliding plate 74 slides on the follower post 73. Two symmetrically distributed connecting rods 75 are fixedly connected to one side wall of the sliding plate 74, and the other end of the connecting rods 75 is fixedly connected to the knob 76. A return spring 77 is fixedly connected to one inner wall of the follower post 73, and the other end of the return spring 77 is fixedly connected to the sliding plate 74. A limiting gear ring 78 is fixedly connected to the groove wall of the receiving groove 71. The knob 76 is ring-shaped. The device is equipped with several meshing teeth 761 that engage with the limiting gear ring 78. When fixing the vehicle sensor, the knob 76 is pulled out from the receiving groove 71. At the same time, driven by the connecting rod 75, the slide plate 74 moves along with it, compressing the return spring 77. Then, the knob 76 is rotated. Driven by the connecting rod 75, the slide plate 74 drives the follower column 73 and the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 drives the bidirectional screw 3 to rotate, thereby driving the two moving blocks 4 to move. After clamping, the slide plate 74 is pushed by the return spring 77, and the knob 76 is reset through the connecting rod 75, so that the knob 76 retracts into the receiving groove 71 to avoid accidental activation. At the same time, the meshing teeth 761 on the knob 76 engage with the limiting gear ring 78 to limit the knob 76 and prevent it from rotating in the non-working state, thus improving stability.

[0029] Specifically, such as Figure 6 and Figure 7 As shown, a clamp for automotive sensors includes a quick-connect mechanism 8 comprising a connecting groove 81, a recess 82, a locking block 83, a pull rod 84, and a clamping spring 85. The bottom wall of the connector 5 has a connecting groove 81, and recesses 82 are formed on both the front and rear side walls of the connecting groove 81. A locking block 83 slides within the recess 82. A pull rod 84 is fixedly connected to the side wall of the locking block 83 away from the connecting groove 81. The other end of the pull rod 84 extends out of the connector 5. A clamping spring 85 is fitted onto the pull rod 84. One end of the clamping spring 85 is fixedly connected to the side wall of the recess 82 away from the connecting groove 81, and the other end... The end is fixedly connected to the locking block 83. When the clamp plate 6 needs to be replaced, pull the lever 84 to move the locking block 83, so that the locking block 83 retracts into the groove 82, and the clamp plate 6 can be removed. When installing the clamp plate 6, insert the connecting block 61 at the top into the connecting groove 81. When inserted, the connecting block 61 will squeeze the locking block 83. The locking block 83 is squeezed and compressed into the groove 82 and squeezes the clamping spring 85. When the connecting block 61 is fully inserted, the locking block 83 is pushed back by the clamping spring 85, fixing the connecting block 61 in the connecting groove 81, thereby completing the installation of the clamp plate 6. The installation and removal method is convenient and quick.

[0030] Specifically, such as Figure 6 As shown, a clamp for an automotive sensor has a connecting block 61 fixedly connected to the top wall of the clamping plate 6. The connecting block 61, in conjunction with the locking block 83, can fix the clamping plate 6.

[0031] Specifically, such as Figure 5 As shown, a clamp for automotive sensors has a pull plate 762 fixedly connected to one side wall of a knob 76, which facilitates pulling the knob 76 out of the receiving groove 71.

[0032] Specifically, such as Figure 6 and Figure 8 As shown, a clamp for automotive sensors has a clamping plate 6 with a slot and a rubber pad 62 inside the slot. The slot can be of various shapes to accommodate automotive sensors of different shapes. The rubber pad 62 can prevent the clamping plate 6 from causing clamping marks on the automotive sensor and has a certain cushioning effect.

[0033] It should be noted that this utility model is a clamp for automotive sensors. In use, the knob 76 is pulled out of the receiving groove 71 by the pull plate 762. At the same time, the slide plate 74 moves along with the connecting rod 75, which compresses the return spring 77. Then, the knob 76 is rotated. Under the action of the connecting rod 75, the slide plate 74 drives the follower column 73 and the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 drives the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 causes the two moving blocks 4 to drive the adapter block 41 to move closer to each other, thereby bringing the two clamping plates 6 closer together and clamping and fixing the sensor. After fixing, the pull plate 762 is released. Under the push of the return spring 77, the slide plate 74 drives the knob 76 to return to its original position through the connecting rod 75, so that the knob 76... The knob 76 retracts into the receiving groove 71 to prevent accidental activation. At the same time, the meshing teeth 761 on the knob 76 will mesh with the limiting tooth ring 78 to limit the knob 76 and prevent it from rotating when not in operation, thus improving stability. When the clamp plate 6 needs to be replaced, pull the lever 84 to move the locking block 83, so that the locking block 83 retracts into the groove 82, and the clamp plate 6 can be removed. When installing the clamp plate 6, insert the connecting block 61 on its top into the connecting groove 81. When inserted, the connecting block 61 will squeeze the locking block 83, and the locking block 83 will be squeezed into the groove 82 and squeeze the clamping spring 85. When the connecting block 61 is fully inserted, the locking block 83 will be pushed back by the clamping spring 85, fixing the connecting block 61 in the connecting groove 81, thus completing the installation of the clamp plate 6. The installation and removal method is convenient and quick.
