Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an anti-theft double-support structure for electric vehicles. Background Art

[0002] Generally, electric vehicles have double supports for parking, and both supports have locking structures. In the prior art, most double support structures have added locking structures, which can not only prevent the double supports from sliding and improve the parking stability of electric vehicles, but also prevent the electric vehicles from being theft-proof by keeping them in a propped-up state, thereby improving the anti-theft performance of electric vehicles. However, in actual applications, since the double supports generally have only a single locking structure, if thieves use powerful tools such as hydraulic shears, the locking structure will directly lose its anti-theft function, and further damage the double support structure, resulting in a general anti-theft effect. To this end, we propose an anti-theft double support structure for electric vehicles. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an anti-theft double-support structure for an electric vehicle.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An anti-theft double-support structure for an electric vehicle is designed, comprising a double-support body, an alarm mechanism one is arranged between the two legs of the double-support body, the alarm mechanism one comprises a double-head telescopic rod, a pressure sensor one and a buzzer two, the pressure sensor one is respectively connected to the two legs of the double-support body, a compression spring one is connected between the movable end of the double-head telescopic rod and the pressure sensor one, a mounting sleeve is fixed on the top of the double-support body, an assembly block with a rotating shaft fixed inside is arranged above the double-support body, a mounting groove is fixed between the assembly block and the mounting sleeve, the alarm mechanism two is arranged in the mounting groove, and locking components are arranged at both ends of the assembly block.

[0006] In the above scheme, both legs of the double-support body are provided with fixing blocks, and the pressure sensor 1 and the buzzer 2 are both installed on the fixing blocks.

[0007] In the above solution, a reinforcement bracket is fixed between the double-head telescopic rod and the mounting sleeve.

[0008] In the above scheme, the second alarm mechanism includes a pressure bracket arranged in the installation groove, a pressure sensor 2 is installed at the bottom end of the pressure bracket, a compression spring 2 is longitudinally installed between the pressure sensor 2 and the top of the pressure bracket, and a buzzer 1 is also installed in the pressure bracket.

[0009] In the above scheme, the locking assembly includes a limit plate fixed to the vehicle body, locking pieces are movably provided at both ends of the assembly block, a locking hole cooperating with the locking piece is opened on the limit plate, and an angle sensor is installed on the rotating shaft.

[0010] In the above solution, the locking member comprises a cylinder mounted on the end of the assembly block, and the stroke end of the cylinder faces the locking hole.

[0011] In the above scheme, the limit plate is a magnetic limit plate, a mounting groove is provided in the limit plate, the locking member comprises an electromagnet with a movable seat fixed at the tail, and a limit rod movably provided on the movable seat is fixed in the mounting groove.

[0012] The advantages and beneficial effects of the utility model are as follows: by setting a double-support body and an alarm mechanism 1, and by extending the double-head telescopic rod outward, the compression spring 1 is in a compressed state, thereby generating an elastic force to expand outwards to the compression spring 1, and then applying it to the pressure sensor 1, so that in daily work, the pressure detected by the pressure sensor 1 is maintained within a certain numerical range. If the two legs of the double-support body are damaged, the distance between the two legs changes, causing the compression spring 1 to be out of the compressed state, thereby causing the indication of the pressure sensor 1 to change significantly and deviate from the set numerical range. Compared with the prior art, when the pressure value detected by the pressure sensor 1 is abnormal, the buzzer 2 is activated. It can alarm and achieve the anti-theft effect. By setting an assembly block, a mounting sleeve, a mounting groove and an alarm mechanism 2, the compression spring 2 is compressed so that the pressure detected by the pressure sensor 2 at its bottom is maintained within a certain numerical range. If the mounting groove and the pressure bracket are sheared from the middle, the pressure bracket will be damaged, causing the compression spring 2 to be out of the compressed state, and then the reading of the pressure sensor 2 will change significantly and deviate from the set numerical range. Compared with the prior art, when the pressure sensor 2 is used, when the detected pressure value is abnormal, the buzzer 1 is started to alarm and achieve the anti-theft effect. Combined with the alarm mechanism 1 and the alarm mechanism 2, the anti-theft effect of the double-support body is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an anti-theft double-support structure for electric vehicles, comprising a double-support body 1, an alarm mechanism 1 is arranged between the two legs of the double-support body 1, the alarm mechanism 1 comprises a double-head telescopic rod 2, a pressure sensor 15 and a buzzer 27, the pressure sensor 15 is respectively connected to the two legs of the double-support body 1, a compression spring 16 is connected between the movable end of the double-head telescopic rod 2 and the pressure sensor 15, wherein the compression spring 16 is always in a compressed state, and a mounting sleeve 9 is fixed on the top of the double-support body 1;

[0021] Specifically, the double-headed telescopic rod 2 includes a sleeve with movable grooves at both ends, adjacent movable grooves are not connected, a movable rod is slidably connected in the movable groove, the end of the movable rod away from the sleeve is connected to a compression spring 6, and both ends of the sleeve are threadedly connected with fastening screws that are tightly pressed against the movable rod to lock the extended length of the movable rod.

[0022] Furthermore, a fixing block 4 is provided on the inner side of both legs of the double-support body 1, and a pressure sensor 5 and a buzzer 7 are both installed on the fixing block 4. Figure 1 As shown, the pressure sensor 15, the compression spring 16, and the double-headed telescopic rod 2 are located in a straight line so as to detect the pressure applied by the compression spring 16;

[0023] Furthermore, a reinforcement bracket 8 is fixed between the double-head telescopic rod 2 and the mounting sleeve 9; a reinforcement sleeve is provided on the middle fixed sleeve of the sleeve of the double-head telescopic rod 2, and the reinforcement bracket 8 is fixed to the reinforcement sleeve, and the reinforcement bracket 8 is in an inverted V shape to enhance stability;

[0024] Specifically, by setting a double-support body 1 and an alarm mechanism 1, and by extending the double-headed telescopic rod 2 outward, the compression spring 6 is placed in a compressed state, thereby generating an elastic force to expand outward on the compression spring 6, which is then applied to the pressure sensor 5. Therefore, during daily operation, the pressure detected by the pressure sensor 5 is maintained within a certain numerical range. If the two legs of the double-support body 1 are damaged, the distance between the two legs changes, causing the compression spring 6 to be out of the compressed state, thereby causing the indication of the pressure sensor 6 to change significantly and deviate from the set numerical range. Compared with the prior art, when the pressure sensor 6 is used, when the detected pressure value is abnormal, the buzzer 2 7 is activated to alarm, thereby achieving an anti-theft effect.

[0025] An assembly block 10 with a rotating shaft 12 fixed therein is provided above the double-support body 1, a mounting groove 11 is fixed between the assembly block 10 and the mounting sleeve 9, and a second alarm mechanism is provided in the mounting groove 11;

[0026] Further, the alarm mechanism 2 includes a pressure bracket 17 arranged in the mounting groove 11, a pressure sensor 2 19 is installed at the bottom end of the pressure bracket 17, a compression spring 2 18 is longitudinally installed between the pressure sensor 2 19 and the top of the pressure bracket 17, and a buzzer 3 is also installed in the pressure bracket 17;

[0027] Specifically, the installation slot 11 is used to hide the alarm mechanism 2, reduce the vigilance of the thief, and induce the thief to cut the installation slot 11, thereby activating the buzzer 13 to alarm.

[0028] Locking components are provided at both ends of the assembly block 10;

[0029] Further, the locking assembly includes a limit plate 14 fixed to the vehicle body, and locking pieces 13 are movably provided at both ends of the assembly block 10. A locking hole 15 cooperating with the locking piece 13 is provided on the limit plate 14. When the limit plate 13 is inserted into the locking hole 15, the double support body 1 is locked. An angle sensor 16 is installed on the rotating shaft 12. In actual application, the state of the electric vehicle at this time can be determined by detecting the rotation angle of the rotating shaft 12 through the angle sensor 16. When the angle sensor 16 detects 90 degrees, the electric vehicle is in a parking state.

[0030] Specifically, in actual application, both ends of the rotating shaft 12 are movably connected to the vehicle body parts, and when the double-support body 1 is stepped on by the foot, the double-support body 1 can be rotated, thereby supporting the body of the electric vehicle;

[0031] Furthermore, the locking member 13 includes a cylinder mounted on the end of the assembly block 10, with the cylinder stroke end facing the locking hole 15; using the angle sensor 16, after the parking is completed, the cylinder piston rod can be automatically extended and inserted into the locking hole 15, thereby preventing the double support body 1 from rotating and preventing the electric vehicle from being pushed;

[0032] Further, the limit plate 14 is a magnetic limit plate, which can be a magnetic block or can be coated with a magnetic coating on the surface of the limit plate 14 to make it magnetic. A mounting groove 20 is provided in the limit plate 14, and the locking member 13 includes an electromagnet with a movable seat 21 fixed at the tail, and a limit rod 22 movably inserted on the movable seat 21 is fixed in the mounting groove 20; in practical applications, the electromagnet is respectively connected to the positive and negative poles of the power supply through a circuit with a double switch, so that the positive and negative poles of the electromagnet are switched, so that the electromagnet switches between the two magnetic properties to achieve a state of adsorption or repulsion with the limit plate 14, and in actual operation, different switches are controlled by a remote controller;

[0033] Specifically, by providing an assembly block 10, a mounting sleeve 9, a mounting groove 11 and an alarm mechanism 2, the compression spring 2 18 is compressed so that the pressure detected by the pressure sensor 2 19 at its bottom is maintained within a certain numerical range. If the mounting groove 11 and the pressure bracket 17 are sheared from the middle, the pressure bracket 17 will be damaged, causing the compression spring 2 18 to be out of the compressed state, thereby causing the reading of the pressure sensor 2 19 to change significantly and deviate from the set numerical range. Compared with the prior art, when the pressure sensor 2 19 is used, when the detected pressure value is abnormal, the buzzer 1 7 is started to alarm, thereby achieving an anti-theft effect. Combined with the alarm mechanism 1 and the alarm mechanism 2, the anti-theft effect of the double-support body 1 is greatly improved.
