DETAILED DESCRIPTION

[0066] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0067] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0068] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0069] Embodiment 1:

[0070] like Figure 1As shown, an embodiment of the present application provides a tire pressure sensor, including a base plate 2001, on the top of which is provided with a chamber 1 2002; a top plate 2003, which is fixedly mounted on the base plate 2001 and is provided with a chamber 2 2004; a lining plate 2005, which is embedded in the top of the chamber 1 2002 and on the top of which is doped with a varistor 2006 and a wire 2007; an electromagnetic shielding layer 2008, which is arranged in the inner cavity of the chamber 2004 and the bottom surface of the lining plate 2005; and a through hole 2009, which passes through the top of the top plate 2003 and is connected with the chamber 2 2004.

[0071] In the embodiment of the present application, a tire pressure sensor as described above is used, and external electromagnetic interference is isolated by setting an electromagnetic shielding layer 2008 located in the inner cavity of chamber 2004 and the bottom surface of the lining plate 2005. The air pressure inside the tire is made the same as the air pressure inside chamber 2004 through the through hole 2009. The varistor 2006 is affected by the air pressure, and the resistance increases or decreases. After the current flows through the varistor 2006, it is output through the wire 2007 and connected to an external device to calculate the air pressure inside the tire. In this way, the tire pressure sensor is protected from electromagnetic interference and the accuracy of tire pressure detection is improved.

[0072] Embodiment 2:

[0073] In this embodiment, a tire pressure sensor processing method is also disclosed, including:

[0074] S1. Obtaining a bottom plate 2001 having a cavity 1 2002 and a top plate 2003 having a cavity 2 2004 by injection molding;

[0075] S2, embedding a liner 2005 at the opening of the chamber 1 2002, and doping a varistor 2006 and a wire 2007 on the liner 2005;

[0076] S3, setting an electromagnetic shielding layer 2008 in the second chamber 2004;

[0077] S4, drilling a through hole 2009 on the top of the top plate 2003 to connect to the second chamber 2004;

[0078] S5. After applying glue on the bottom plate 2001, align the chamber 1 2002 with the chamber 2 2004, and press the bottom plate 2001 and the top plate 2003 together through an assembly device.

[0079] In this embodiment, due to the adoption of the above method, the process is simple, the chip size is reduced, and the manufacturing cost is reduced.

[0080] Embodiment 3:

[0081] In this embodiment, in addition to the structural features of the aforementioned embodiments, preferably, the thickness of the electromagnetic shielding layer 2008 is 12-15 um.

[0082] In this embodiment, due to the adoption of the above structure, by setting the electromagnetic shielding layer 2008 to 12-15 um, it has an electromagnetic shielding effect while saving material consumption.

[0083] Embodiment 4:

[0084] like Figures 2 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, preferably, the electromagnetic shielding layer 2008 is made of one of copper, silver or nickel.

[0085] In this embodiment, due to the adoption of the above structure, the user can select one of copper, silver or nickel materials according to actual conditions, which is convenient for the user's actual operation.

[0086] Embodiment 5:

[0087] In this embodiment, an assembly device is also disclosed, including a body 1, which has a pressing chamber 2 and a lifting chamber 3 inside; an upper pressing platform 4, which is installed on the top of the pressing chamber 2; a lifting plate 5, which is movably installed in the lifting chamber 3 and driven to lift and lower by a lifting drive mechanism 6; a hollow lower pressing platform 7, which is fixedly installed on the top of the lifting plate 5 and has a clamp, and the clamp includes a limit plate group 8 and a pressure mechanism 9, and the limit plate group 8 and the pressure mechanism 9 are respectively installed at the diagonals of the top of the hollow lower pressing platform 7 to cooperate with each other to fix the bottom plate 2001 and the top plate 2002 diagonally, one end of the pressing chamber 2 is open, and the lifting chamber 3 is located at the bottom of the body 1 and is connected with the pressing chamber 2.

[0088] In this embodiment, due to the adoption of the above-mentioned structure, the bottom plate 2001 is placed on the top of the hollow lower pressing platform 7, and its two opposite corners are respectively abutted against the limit plate group 8 and the pressure mechanism 9, and the pressure mechanism 9 is used to apply pressure to one corner of the bottom plate 2001 so that the other corner is tightly fitted with the limit plate group 8. After glue is dispensed on the bottom plate 2001, the top plate 2003 is placed above the bottom plate 2001 so that the chamber 2 2004 faces the bottom plate 2001, so that the opposite corner of the bottom plate 2001 is also fixed by the pressure test mechanism and the limit plate group 8, and the lifting drive mechanism 6 is operated to drive the top plate 2003 to move upward. The lifting plate 5 is raised to make the hollow lower pressing platform 7 approach the upper pressing platform 4, and the top surface of the top plate 2003 is in contact with the bottom surface of the upper pressing platform 4. The lifting plate 5 continues to rise under the operation of the lifting drive mechanism 6 to press the bottom plate 2001 and the top plate 2003. After the pressing is completed, the lifting plate 5 is moved away from the upper pressing platform 4 under the action of the lifting drive mechanism 6, and the tire pressure sensor obtained by pressing the bottom plate 2001 and the top plate 2003 is removed from the hollow lower pressing platform 7 to complete the pressing process. The above technical solution replaces manual work, and the work efficiency and pressing accuracy are improved.

[0089] Embodiment 6:

[0090] In this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting drive mechanism 6 includes a groove 601, which is arranged at the bottom of the lifting chamber 3; a pair of connecting rod groups, which are respectively arranged at both ends of the lifting chamber 3 and each include two arms 602 whose ends are hinged to each other; a connecting arm 603, whose two ends are respectively hinged to the mutual hinge points of each arm 602 on both sides; a turntable 604, which is driven by a reduction motor and connected to the connecting arm 603 through a linkage mechanism 10, and the ends of each arm 602 that are away from each other are respectively hinged to the bottom surface of the lifting plate 5 and the bottom surface of the lifting chamber 3. When the turntable 604 rotates, the linkage mechanism 10 drives the connecting arm 603 to swing back and forth.

[0091] In this embodiment, due to the adoption of the above-mentioned structure, when the lifting plate 5 needs to be raised or lowered, the reduction motor drives the turntable 604 to rotate, and the turntable 604 drives the connecting arm 603 to move back and forth left and right through the linkage mechanism 10. The upper support arms 602 and the lower support arms 602 are respectively arranged parallel to each other. During the movement of the connecting arm 603, the angle between the upper support arms 602 and the lower support arms 602 increases or decreases, so that the distance in the vertical direction between the upper support arms 602 and the lower support arms 602, which are away from each other at one end, increases or decreases. The lifting plate 5 is small, driving the lifting plate 5 to cyclically lift and lower in the lifting chamber 3, but the speed of the reduction motor is slow, so that the workers have enough time to remove the tire pressure sensor placed on the hollow lower pressing platform 7 to complete the pressing during the descent of the lifting plate 5, and complete a series of actions such as preventing the bottom plate 2001, dispensing glue, placing the top plate 2003 and fixing the bottom plate 2001 and the top plate 2003 between the pressure test mechanism and the limit plate group 8 through the pressure-applying mechanism 9 before the lifting plate 5 rises. In this way, there is no need to stop the machine for loading and unloading operations, thereby improving work efficiency.

[0092] Embodiment 7:

[0093] In this embodiment, in addition to the structural features of the aforementioned embodiments, the linkage mechanism 10 includes a swing arm 1001, the middle part of which is rotatably installed in the lifting chamber 3 through a rotating shaft 1002; a connecting rod 1003, one end of which is hinged to the bottom end of the swing arm 1001, and the other end is hinged to the eccentric part of the surface of the turntable 604; a transmission block 1004, which is installed in the middle of the connecting arm 603 through a through groove 1005; a transmission groove 1006, which is arranged at the top of the swing arm 1001, and the top of the swing arm 1001 is movably inserted in the through groove 1005, and the transmission block 1004 is slidably matched with the transmission groove 1006.

[0094] In this embodiment, due to the adoption of the above-mentioned structure, as the turntable 604 rotates, the connecting rod 1003 pushes and pulls the bottom end of the swing arm 1001, causing the swing arm 1001 to swing around the rotating shaft 1002, and its top end moves in the transmission groove 1006, and the transmission block 1004 slides in the transmission groove 1006. The transmission block 1004 drives the connecting arm 603 to move back and forth left and right as the top end of the swing arm 1001 swings. The lever principle is generated by the arrangement of the swing arm 1001 and the rotating shaft 1002. The length of the force arm is increased by increasing the length of the lower part 13 of the swing arm 1001, so that the upper part 12 of the swing arm 1001 can more easily "pry" the connecting arm 603. In this way, the stability of the lifting plate 5 during lifting and lowering is improved, and a sufficiently large pressure can be applied to the hollow lower pressing table 7, thereby improving the pressing effect.

[0095] Embodiment 8:

[0096] In this embodiment, in addition to the structural features of the aforementioned embodiments, the limit plate group 8 includes a transverse groove 801, which passes through the hollow pressing platform 7 from top to bottom; a slider 802, which is provided with a screw hole and is movably installed in the inner cavity of the hollow pressing platform 7 and can be movably inserted through the transverse groove 801 at the top and extend out of the hollow pressing platform 7; a screw rod 803, which is threadedly connected to the screw hole and one end of which extends out of the hollow pressing platform 7 and is equipped with a handwheel 804; a fixed edge 805, which is installed on the top of the hollow pressing platform 7 and is arranged at a right angle to the slider 802.

[0097] In this embodiment, due to the adoption of the above-mentioned structure, when the top plate 2003 and the bottom plate 2001 are fixed, the two surfaces of the top plate 2003 and the bottom plate 2001 that are connected to each other at the same diagonal are respectively abutted against the inner side of the fixed edge 805 and the inner side of the slider 1 802, and by the setting of the screw rod 803 and the hand wheel 804, the hand wheel 804 is rotated, and the screw rod 803 and the screw hole are matched to drive and move the slider 1 802 in the transverse groove 801. After the position of the slider 1 802 is adjusted according to the width of the top plate 2003 and the bottom plate 2001, the pressure mechanism 9 is cooperated to apply pressure to the opposite diagonals of the top plate 2003 and the bottom plate 2001, so that the top plate 2003 and the bottom plate 2001 are fixed between the pressure mechanism 9 and the fixed edge 805 and the slider 1 802. In this way, the top plate 2003 and the bottom plate 2001 are fixed before being pressed together, thereby improving the accuracy of the top plate 2003 and the bottom plate 2001 when being pressed together.

[0098] Embodiment 9:

[0099] In addition to the structural features of the aforementioned embodiments, the pressure mechanism 9 includes a slide groove 901, which is tilted and arranged at the bottom of the inner cavity of the hollow pressing platform 7; a slider 902, which is movably installed in the slide groove 901; a pull rod 903, one end of which is fixedly connected to the slider 902, and the other end is movably inserted through the side wall of the hollow pressing platform 7 and extends out of it; a spring 904, which is sleeved on the outside of the pull rod 903 and is located between the slider 902 and the inner wall of the hollow pressing platform 7; a pair of slide grooves 905, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 901 and parallel to it; a pair of slides 906, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 901 and parallel to it; a pair of slides 907, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 907 and parallel to it; a pair of slides 908, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 908 and parallel to it; a pair of slides 909, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 909; a pair of slides 901, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 901 and parallel to it; a pair of slides 909, which are arranged at the bottom of the inner cavity of the hollow pressing platform 7 and are symmetrically distributed on both sides of the slide groove 901 and parallel to it; a pair of slides 909 Block three 906, which are slidably installed in each slide groove two 905; a pair of oblique displacement grooves 907, which pass through the top of the hollow pressing platform 7 from top to bottom and are symmetrically distributed on both sides of the slide groove one 901; a pair of sliders four 908, which are respectively fixedly installed on the top of each slider three 906 and whose top ends movably pass through each oblique displacement groove 907 and then extend out of the hollow pressing platform 7; slider five 909, which is fixedly installed on the top of slider two 902; a transmission arm 910, one end of which is hinged to one side slider three 906, and the other side is provided with a balancing groove 911 for sliding cooperation with the other slider three 906, and the slider five 909 is slidably installed in the balancing groove 911.

[0100] In this embodiment, due to the adoption of the above-mentioned structure, the bottom plate 2001 and the top plate 2003 are prevented from pulling the pull rod 903 toward the outside of the hollow pressing platform 7, driving the slider 2 902 in the slide groove 1 901, the slider 3 906 in the slide groove 2 905, and the slider 4 908 in the oblique displacement groove 907 to move away from the limit plate group 8 at the same time. The spring 1 904 is compressed to store elastic potential energy. After the bottom plate 2001 and the top plate 2003 are placed on the top of the hollow pressing platform 7 and the adjacent surfaces at the same diagonal are respectively in contact with the limit plate group 8, the pull rod 903 is released, and the spring 1 904 without external force constraints releases the elastic potential energy to generate kinetic energy to make the slider 2 902 move in the slide groove 1 901 toward the limit plate group 8. At the same time, through the cooperation of the balancing groove 911 and the slider 5 909, one of the sliders 3 906 is driven to move in the corresponding oblique groove toward the limit plate group 8. The slider three 906 abuts against one side wall of the bottom plate 2001 and the top plate 2003, and the other slider three 906 slides in the corresponding inclined groove toward the direction close to the limit plate group 8 under the cooperation of the balancing groove 911, the slider five 909 and the slider two 902, until a pair of slider three 906 abuts against the diagonally adjacent side walls of the bottom plate 2001 and the top plate 2003 respectively, and the slider two 902 is pressed by the setting of the spring one 904, so that the pressure is transmitted to the pair of slider three 906 after passing through the slider five 909 and the balancing groove 911, so that the outer wall of each slider three 906 is tightly abutted against the diagonally adjacent side walls of the bottom plate 2001 and the top plate 2003, so that the bottom plate 2001 and the top plate 2003 are firmly clamped, and through the setting of the balancing groove 911, a pair of slider three 906 can fix the diagonally adjacent sides of the bottom plate 2001 and the top plate 2003 of different sizes, thereby improving the application range of the equipment.
