Abstract
Description
Technical Field

[0034] The following describes two implementation methods of the present application in detail with reference to the accompanying drawings.
[0035] The first implementation method:
[0036] Figure 1-7 A vandal-resistant housing for a vehicle GPS locator is shown, including a housing for mounting a circuit board 5. The housing comprises an inner cover 1 and an outer cover 2 that fits over the inner cover 1. The inner cover 1 is fixed to the vehicle frame via a plurality of mounting bolts 7 distributed circumferentially on its inner side. The inner cover 1 is secured to the outer cover 2 via a clamping assembly 3.
[0037] See also Figure 3 and Figure 4 The lower part of the inner cover 1 is provided with a plug-in slot 1021 for inserting the outer cover 2. The card assembly 3 includes a plurality of card blocks 8 that are slidably connected to the inner cover 1. The card blocks 8 are located in the side walls of the plug-in slot 1021. A spring rod 9 is fixedly connected to the side of the card block 8 away from the plug-in slot 1021. The spring rod 9 enables the card block 8 to expand and contract horizontally when squeezed. A card slot 201 is provided on the inner wall of the outer cover 2 to cooperate with the card block 8. When the outer cover 2 is inserted into the plug-in slot 1021, the card block 8 is inserted into the card slot 201 under the action of the spring rod 9.
[0038] See also Figure 3 and Figure 4 The clamping assembly 3 also includes a locking mechanism, which includes a main piston cylinder 10 fixedly connected to the inner cover 1, the main piston cylinder 10 is filled with hydraulic oil, a plurality of auxiliary piston cylinders 14 are fixedly connected to the outside of the main piston cylinder 10, and an auxiliary piston rod 15 is slidably connected to the auxiliary piston cylinder 14. The auxiliary piston rod 15 passes through the mounting bolt 7 and abuts against the clamping block 8. The main piston cylinder 10 is slidably connected to the main piston rod 11, and the lower end of the main piston rod 11 abuts against a first spring 13 installed in the main piston cylinder 10, and the upper end of the main piston rod 11 abuts against the collapse frame 4, and the upper end of the collapse frame 4 abuts against the inner wall of the outer cover 2; an elastic pin 12 for limiting the main piston rod 11 is fixedly connected to the main piston cylinder 10.
[0039] For details, please refer to Figure 7 , when installing the shell, the following steps are included:
[0040] Step 1: Place the inner cover 1 on the frame mounting position, and then tighten the mounting bolts 7 to fix the inner cover 1 on the frame;
[0041] Step 2: First, place the circuit board 5 into the inner cover 1, then place the crush frame 4 into the inner cover 1 and make it abut against the upper end of the main piston rod 11, and finally, sleeve the outer cover 2 onto the outer side of the inner cover 1;
[0042] Step 3: Press the outer cover 2 downward so that it is inserted into the insertion slot 1021. At the same time, the clamping block 8 is inserted into the clamping slot 201 under the action of the spring rod 9. During this process, the outer cover 2 squeezes the main piston rod 11 through the collapse frame 4, so that the hydraulic oil in the main piston cylinder 10 is injected into the auxiliary piston cylinder 14, causing the auxiliary piston rod 15 to extend outward. The auxiliary piston rod 15 passes through the mounting bolt 7 and abuts against the clamping block 8.
[0043] Compared with the traditional positioner housing, the present invention uses the mounting bolts 7 located on the inner side of the inner cover 1 and the plug-in slot 1021 opened on the inner cover 1, and uses the block 8 connected with the spring rod 9 to make the outer cover 2 and the inner cover 1 mutually connected, so that the joint seam between the inner cover 1 and the outer cover 2 and the mounting bolts 7 are hidden, thereby improving the anti-pry and anti-disassembly capabilities of the housing; at the same time, through the main piston cylinder 10 and the auxiliary piston cylinder 14 linked with the outer cover 2, the block 8 connected to the card slot 201 is clamped by the auxiliary piston rod 15 abuts and limits, further improving the clamping stability and anti-pry ability of the inner cover 1 and the outer cover 2; in addition, the crush frame 4 abuts against the outer cover 2, and absorbs the hammering kinetic energy of the outer cover 2 by active deformation when the outer cover 2 is hammered, thereby further improving the anti-destruction ability of the shell; in addition, the auxiliary piston rod 15 passing through the mounting bolt 7 limits the mounting bolt 7, reducing the probability of the mounting bolt 7 loosening when the shell is hammered, further improving the stability of the connection between the shell and the frame, and improving the anti-riot demolition ability.
[0044] It should be noted that a positioning chip module and a communication module are installed on the circuit board 5 .
[0045] See also Figure 5 The inner cover 1 includes an annular enclosure portion 101 and a horizontal portion 102 integrally formed with the enclosure portion 101. The plug-in groove 1021 is opened on the horizontal portion 102 and is located on the outside of the enclosure portion 101. The horizontal portion 102 is provided with a sliding groove 1022 for accommodating the block 8. The spring rod 9 is fixedly connected to the inner wall of the sliding groove 1022. The horizontal portion 102 is also provided with a bolt groove 1023 for the mounting bolt 7 to pass through. The horizontal portion 102 is provided with a connecting groove 1025 for accommodating the secondary piston cylinder 14 at the inner side of the bolt groove 1023. The connecting groove 1025 and the sliding groove 1022 are connected by a through groove 1024 that passes through the bolt groove 1023. The mounting bolt 7 is provided with a through hole that communicates with the through groove 1024. The inner side of the connecting groove 1025 is connected with a center groove 1026 for fixing the main piston cylinder 10.
[0046] Specifically, before the outer cover 2 is inserted into the plug-in slot 1021, the front portion of the block 8 is inserted into the plug-in slot 1021 under the action of the spring rod 9. When the outer cover 2 is inserted into the plug-in slot 1021 and contacts the block 8, the block 8 gradually retracts into the sliding slot 1022 until the block 8 is inserted into the slot 201 under the action of the spring rod 9.
[0047] See also Figure 3 and Figure 6 The card block 8 is a wedge-shaped block, and includes a front portion that engages with the card slot 201 and a rear portion that abuts against the sliding slot 1022. The front section is a right-angled trapezoid and the rear section is a rectangle.
[0048] Specifically, when the outer cover 2 is subjected to force, the front portion of the clamping block 8 is located in the clamping groove 201 and the rear portion is located in the sliding groove 1022 , so that the clamping block 8 has a better clamping effect and improves the anti-destruction capability of the shell.
[0049] See also Figure 3 and Figure 4 The spring rod 9 is a sleeve-type spring telescopic rod. The block 8 is provided with a cylindrical cavity for accommodating the spring rod 9. The elastic pin 12 includes a fixed cylinder, a plug-in rod slidably connected to the fixed cylinder, and a third spring installed in the fixed cylinder and abutting against the plug-in rod. The fixed cylinder is fixedly connected to the main piston cylinder 10, and a positioning hole 1101 is provided on the side wall of the main piston rod 11 to cooperate with the plug-in rod.
[0050] Specifically, the elastic pin 12 is used to lock and limit the main piston rod 11, thereby locking and limiting the auxiliary piston rod 15.
[0051] See also Figure 3 The circuit board 5 is connected to the vibration damping frame 6, and the vibration damping frame 6 includes a mounting sleeve 19 fixedly connected to the circuit board 5. The mounting sleeve 19 is slidably connected to the serial bolt 18. The lower end of the serial bolt 18 is fixedly connected to the fixed frame 16. The fixed frame 16 is fixedly connected to the inside of the inner cover 1. The upper part of the serial bolt 18 is slidably connected to the movable frame 17. The movable frame 17 is slidably connected to the inner wall of the inner cover 1. The second spring 20 is abutted on both sides of the mounting sleeve 19.
[0052] Specifically, when the housing is struck and vibrates, the circuit board 5 moves up and down along the serial bolts 18 along with the mounting sleeve 19 , thereby reducing damage to the circuit board 5 caused by the vibration.
[0053] Second implementation method:
[0054] Figure 3 and Figure 8-10The present invention shows an anti-destruction shell for a vehicle GPS locator. Based on the first embodiment, a accommodating chamber 202 is provided on the upper part of the outer cover 2. A liquid storage cylinder 21 is fixedly connected to the accommodating chamber 202. A membrane cover 22 is fixedly connected to the upper end of the liquid storage cylinder 21. The liquid storage cylinder 21 is filled with lubricating oil. A puncture needle 23 for piercing the membrane cover 22 is provided above the membrane cover 22. The puncture needle 23 is hinged to the inner wall of the accommodating chamber 202. A seepage hole 203 communicating with the accommodating chamber 202 is provided on the upper part of the outer cover 2. The outer cover 2 is made of one of polycarbonate or carbon fiber reinforced plastic.
[0055] For details, please refer to Figure 10 When a person violently hammers the outer cover 2, the outer cover 2 vibrates and deforms, causing the puncture needle 23 to pierce the membrane cover 22, and the lubricating oil in the liquid reservoir 21 is discharged into the accommodating chamber 202. As the outer cover 2 vibrates, the lubricating oil flows from the seepage hole 203 to the surface of the outer cover 2, and the lubricating oil forms an oil film on the surface of the outer cover 2, so that the object used for hammering or the cutting saw blade cannot contact the surface of the outer cover 2 well, easily slips, and cannot transmit hammering or cutting energy, thereby improving the anti-destruction ability; it should be noted that the membrane cover 22 is made of plastic film material and is fixed to the upper opening position of the liquid reservoir 21 by bonding.
[0056] See also Figure 9 The upper end of the liquid storage cylinder 21 adopts an inclined opening structure, the upper end of the puncture needle 23 is hinged to the inner wall of the accommodating cavity 202 through a hinge seat 24, the hinge seat 24 is a ball hinge support, the lower end of the puncture needle 23 is a tip and a counterweight ball 25 is fixedly connected to the side close to the tip.
[0057] Specifically, by providing the inclined-mouth liquid storage cylinder 21 and the puncture needle 23 fixed with the weighted ball 25 , the puncture needle 23 is more likely to swing when the outer cover 2 vibrates, thereby making it easier to puncture the membrane cover 22 .
[0058] See also Figure 8 and Figure 9 A first vibrating plate 26 cooperating with the puncture needle 23 is fixedly connected to the liquid storage cylinder 21 . When the puncture needle 23 swings toward the direction of the first vibrating plate 26 , it hits the first vibrating plate 26 .
[0059] Specifically, the puncture needle 23 strikes the first vibrating plate 26, causing the first vibrating plate 26 to vibrate, thereby enlarging the puncture hole on the membrane cover 22 and accelerating the discharge of the lubricant in the liquid storage cylinder 21, thereby increasing the discharge speed of the lubricant.
[0060] See also Figure 9 A plurality of second vibration plates 27 are fixedly connected to the counterweight ball 25 .
[0061] Specifically, during the swinging process of the counterweight ball 25, the second vibration plate 27 is driven to vibrate, and the second vibration plate 27 knocks the lubricating oil droplets flowing into the accommodating chamber 202, so that the lubricating oil is fully diffused, further increasing the speed of the lubricating oil seeping out. It should be noted that the first vibration plate 26 and the second vibration plate 27 are both made of metal sheets.
[0062] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
