DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0028] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by those skilled in the art to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present invention.

[0029] The present invention discloses a hydraulic anti-theft device. When the driver sits in the driver's seat, the gravity index parameter and / or sitting habit index parameter of the driver can be obtained by using a gravity sensor and / or a distance sensor installed at the driver's seat. The driver's starting habit index parameter can also be obtained by using a pilot pressure sensor and / or a pilot speed sensor installed on the starting device. According to at least one of the driver's gravity index parameter, sitting habit index parameter and starting habit index parameter, it is judged whether the current driver is a designated driver. If the driver is not a designated driver, the corresponding alarm device can be activated to avoid the loss of the vehicle. Further, the present invention discloses a hydraulic anti-theft device, which uses the overflow energy of the hydraulic system to power each functional module. For example, the overflow energy of the hydraulic system can power the sensor, which is not only energy-saving and environmentally friendly, but also not easy to dismantle and safer.

[0030] Example 1

[0031] In this embodiment, see Figure 1 , shows a hydraulic anti-theft device, which includes: a control module 3, a sensor module 4, a hydraulic module 2 and a hydraulic pilot switch 1. When the hydraulic pilot switch 1 is turned on:

[0032] The overflow energy of the hydraulic module 2 is used to provide working energy for the control module 3 and the sensor module 4; the control module 3 receives the monitoring signal obtained by the sensor module 4 installed at a preset position, and determines whether the monitoring signal is within the preset signal range. If it is within the preset signal range, the hydraulic pilot switch 1 is kept open; if it exceeds the preset signal range, the hydraulic pilot switch 1 is closed.

[0033] The hydraulic module 2 generally includes: power elements, actuators, control elements, auxiliary elements and hydraulic oil. The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic module 2, and can provide power to the entire hydraulic module 2. For example, the structural forms of the hydraulic oil pump generally include gear pumps, vane pumps and plunger pumps; the function of the actuator (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy and drive the load to perform linear reciprocating motion or rotary motion; the control element (various hydraulic valves) controls and adjusts the pressure, flow and direction of the liquid in the hydraulic module 2; the hydraulic oil is the working medium for transmitting energy in the hydraulic module 2, and there are several major categories such as various mineral oils, emulsions and synthetic hydraulic oils.

[0034] The hydraulic module 2 in this embodiment also includes an energy conversion unit for converting pressure energy into electrical energy to power the control module 3 and the sensor module 4. Furthermore, after the pressure energy is converted into electrical energy, the backup power supply of the control module 3 and the sensor module 4 can be charged to ensure that when the hydraulic module 2 stops working, the backup power supply is used to power the control module 3 and the sensor module 4.

[0035] When the hydraulic module 2 is started by the hydraulic pilot switch 1, overflow energy will be generated. The overflow pressure energy will be converted into electrical energy by the energy conversion unit to provide working energy for the control module 3 and the sensor module 4. This not only avoids overflow energy loss and is beneficial to energy saving, but also eliminates the need to set up additional power supply devices for the control module 3 and the sensor module 4. On the one hand, it can save the cost of the anti-theft device, and on the other hand, it can prevent the power supply device from being damaged or removed, affecting the anti-theft function.

[0036] Furthermore, the control module 3 receives the monitoring signal obtained by the sensor module 4 and determines whether the monitoring signal is within a preset signal range. If it is within the preset signal range, the hydraulic pilot switch 1 is kept open; if it exceeds the preset signal range, the hydraulic pilot switch 1 is closed.

[0037] For further information, see Figure 2 The sensor module 4 includes at least one of a gravity sensor 41 , a distance sensor 42 , a pilot pressure sensor 43 and a pilot speed sensor 44 .

[0038] Exemplarily, the gravity sensor 41 can be installed under the driver's seat. When the driver sits on the driver's seat, the gravity sensor 41 obtains the driver's gravity index parameter, and the control module 3 compares the gravity index parameter obtained by the gravity sensor 41 with the preset gravity index range. If the gravity index parameter is within the gravity index range, it indicates that the current driver meets the preset gravity conditions, and the hydraulic pilot switch 1 can be kept open. If the gravity index parameter exceeds the gravity index range, it indicates that the current driver does not meet the preset gravity conditions, and the control module 3 can close the hydraulic pilot switch 1.

[0039] Exemplarily, the distance sensor 42 can be installed on the backrest of the driver's seat. When the driver sits on the driver's seat, the distance sensor 42 obtains the distance index parameter between the driver and the backrest. The control module 3 compares the distance index parameter obtained by the distance sensor 42 with the preset distance index range. If the distance index parameter is within the distance index range, it indicates that the current driver meets the preset distance condition, and the hydraulic pilot switch 1 can be kept open. If the distance index parameter exceeds the distance index range, it indicates that the current driver does not meet the preset distance condition, and the control module 3 can close the hydraulic pilot switch 1.

[0040] Exemplarily, the pilot pressure sensor 43 can be installed at the starting device. When the driver starts the vehicle through the starting device, the pilot pressure sensor 43 obtains the pressure index parameter used by the driver for starting. The control module 3 compares the pressure index parameter obtained by the pilot pressure sensor 43 with the preset pressure index range. If the pressure index parameter is within the pressure index range, it indicates that the current driver meets the preset pressure condition, and the hydraulic pilot switch 1 can be kept open. If the pressure index parameter exceeds the pressure index range, it indicates that the current driver does not meet the preset pressure condition, and the control module 3 can close the hydraulic pilot switch 1.

[0041] Exemplarily, the pilot speed sensor 44 can be installed at the starting device. When the driver starts the vehicle through the starting device, the pilot speed sensor 44 obtains the speed index parameter used by the driver for starting. The control module 3 compares the speed index parameter obtained by the pilot speed sensor 44 with the preset speed index range. If the speed index parameter is within the speed index range, it indicates that the current driver meets the preset speed condition, and the hydraulic pilot switch 1 can be kept open. If the speed index parameter exceeds the speed index range, it indicates that the current driver does not meet the preset speed condition, and the control module 3 can close the hydraulic pilot switch 1.

[0042] It can be understood that the sensor module 4 includes one or more of a gravity sensor 41, a distance sensor 42, a pilot pressure sensor 43 and a pilot speed sensor 44. If it includes multiple types, it detects in turn whether multiple index parameters meet the corresponding preset index ranges. If they all meet, the hydraulic pilot switch 1 can be kept open. If there are non-compliant indicators, the control module 3 can close the hydraulic pilot switch 1.

[0043] This embodiment discloses a hydraulic anti-theft device. On the one hand, the overflow pressure energy is converted into electrical energy by the energy conversion unit of the hydraulic module, and then the sensor module 4 and the control module 3 are powered, which is not only energy-saving and environmentally friendly, but also not easy to dismantle and safer. On the other hand, it can be judged whether the current driver is the designated driver according to the index parameters obtained by the sensor installed at the designated position. If the driver is not the designated driver, the hydraulic pilot switch 1 can be turned off to prohibit the vehicle from starting.

[0044] Example 2

[0045] In this embodiment, see Figure 2 The hydraulic anti-theft device also includes a positioning module 5. The energy conversion unit of the hydraulic module 2 converts the overflow pressure energy into electrical energy to provide working energy for the positioning module 5; the control module 3 receives the location information obtained by the positioning module 5 and reports the location information to the management end.

[0046] The energy conversion unit of the hydraulic module 2 can provide working energy for the positioning module 5 after converting the overflow pressure energy into electrical energy, which not only avoids overflow energy loss and is beneficial to energy saving, but also eliminates the need to set up an additional power supply device for the positioning module 5, which can save costs.

[0047] The positioning module 5 includes a GPS positioning unit and / or a satellite positioning unit. The control module 3 can receive the position information obtained by the positioning module 5 and report the position information to the management end through the network. The position information of the vehicle can be monitored at all times, which is conducive to the recovery of the vehicle when the vehicle is lost.

[0048] Furthermore, the hydraulic anti-theft device also includes a communication module 6. After the energy conversion unit of the hydraulic module 2 converts the overflow pressure energy into electrical energy, it is also used to provide working energy for the communication module 6; the control module 3 sends the location information to the management end through the communication module 6.

[0049] The energy conversion unit of the hydraulic module 2 can provide working energy for the communication module 6 after converting the overflow pressure energy into electrical energy, thereby avoiding overflow energy loss, being beneficial to energy saving, and eliminating the need to set up an additional power supply device for the communication module 6, thereby saving costs.

[0050] The communication module 6 includes a text message sending unit, the management end includes a mobile phone, and the control module 3 sends the location information in the form of a text message to the designated driver's mobile phone through the communication module 6.

[0051] Furthermore, the hydraulic anti-theft device also includes an alarm module 7. After the energy conversion unit of the hydraulic module 2 converts the overflow pressure energy into electrical energy, it is also used to provide working energy for the alarm module 7; when the monitoring signal exceeds the signal range, the control module 3 controls the alarm module 7 to sound an alarm.

[0052] The energy conversion unit of the hydraulic module 2 can provide working energy for the alarm module 7 after converting the overflow pressure energy into electrical energy, thereby avoiding overflow energy loss, being beneficial to energy saving, and eliminating the need to set up an additional power supply device for the alarm module 7, thereby saving expenses.

[0053] The alarm module 7 includes at least one of an acoustic alarm unit and a light alarm unit. When the monitoring signal exceeds the signal range, the control module 3 controls the alarm module 7 to issue an audible alarm and / or a light alarm.

[0054] Furthermore, the hydraulic anti-theft device also includes a self-learning module 8. After the energy conversion unit of the hydraulic module 2 converts the overflow pressure energy into electrical energy, it is also used to provide working energy for the self-learning module 8; the self-learning module 8 is used to record the monitoring signal obtained by the sensor module 4 within a preset time period, calculate the average value of the same type of monitoring signal within the preset time period, determine the corresponding signal range according to the average value, and send the corresponding signal range to the control module 3.

[0055] The energy conversion unit of the hydraulic module 2 can provide working energy for the self-learning module 8 after converting the overflow pressure energy into electrical energy, thereby avoiding overflow energy loss, being beneficial to energy saving, and eliminating the need to set up an additional power supply device for the self-learning module 8, thereby saving costs.

[0056] Exemplarily, the self-learning module 8 can pre-record the monitoring signals obtained by the sensor module 4 within a week, calculate the average value of the same type of monitoring signals within a week, and determine the corresponding signal range based on the average value. For example, the signal range can be the average value + 0.02 times the average value to the average value - 0.02 times the average value, and send the corresponding signal range to the control module 3.

[0057] It is understandable that the driver can update the signal range according to personal needs, and the signal range can be updated through the self-learning module 8.
