[0098] The following will be combined with the drawings in the embodiments of this article to clearly and completely describe the technical solutions in the embodiments of this article. Obviously, the described embodiments are only part of the embodiments of this article, not all of the embodiments. Based on the embodiments of this article, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this article.

[0099] It should be noted that the terms "first", "second", etc. in the specification and claims of this article and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this article described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0100] like Figure 1 The schematic diagram of a locking device state detection device shown includes: a driving mechanism 1, a locking rod 2 and a busbar 3 connected in sequence;

[0101] The driving mechanism 1 drives the locking rod 2 to reciprocate, so that the locking device enters a locked state or an unlocked state. The locking rod 2 is provided with a spring sheet 4, and the spring sheet 4 is in contact with the busbar 3.

[0102] When the spring piece 4 follows the locking rod 2 to perform reciprocating motion, it contacts with different positions of the busbar 3; the busbar 3 and the spring pieces 4 contacting at different positions form different circuits, triggering different electrical signals, which are used to indicate the state of the locking rod 2.

[0103] By adopting the above technical solution, when the spring sheet follows the locking rod to perform reciprocating motion, it contacts different positions of the busbar; the spring sheets contacting the busbar at different positions form different circuits and trigger different electrical signals, thereby realizing the indication of the opening state, movement state and terminal state of the locking rod through a spring sheet and the busbar.

[0104] In this article, the driving mechanism 1 is used to drive the locking rod 2 to perform reciprocating motion. In some cases, the locking rod 2 may be blocked due to improper operation by the user, so that the locking rod 2 cannot be extended to the locked position, or the locking rod 2 cannot be retracted into the lock. Therefore, the spring clip 4 can be fixed to the locking rod 2. When the locking rod 2 moves, the spring clip 4 and the busbar 3 form different circuits. Since different circuits have different resistance values, the output electrical signals are different, and then the current state of the locking rod 2 is fed back through various electrical signals.

[0105] like Figure 2 The schematic diagram of the spring piece shown in the figure, in this article, the spring piece 4 includes a fixed section 41, an extension section 42 and an arc section;

[0106] The fixed section 41 is fixedly connected to the locking rod 2 and connected to the extending section 42;

[0107] The extending section 42 forms an oblique angle with the fixing section 41 and extends toward the contact section 31;

[0108] The arc segment 43 is semicircular, and one end of the semicircle is connected to the extension segment 42 , and the other end extends outward. The arc segment 43 is in contact with the contact segment 31 .

[0109] In this article, the fixed section 41 of the spring piece 4 can be fixedly connected to the head end of the lock rod 2 by bolts, and in order to ensure that the spring piece 4 has a certain elasticity, the extension section 42 and the fixed section 41 can form a certain angle, and in order to ensure that the spring piece 4 can move freely on the busbar 3 and maintain contact when the lock rod 2 moves up and down, the angle can be selected to be 30-45°. In this article, the arc section 43 is semicircular on the side, and the semicircle can ensure that the arc section 43 and the busbar 3 will not be blocked when the lock rod 2 moves up and down.

[0110] like Figure 3 The busbar schematic diagram shown, as an embodiment of this article, the busbar 3 includes a contact segment 31 and a conductive segment 32;

[0111] The contact segment 31 is connected to the conductive segment 32;

[0112] like Figure 4 As shown in the schematic diagram of the contact section, the contact section 31 includes a first metal strip 311, a second metal strip 312 and a third metal strip 313; in this article, the width and thickness of the first metal strip 311, the second metal strip 312 and the third metal strip 313 can be kept consistent.

[0113] The first metal belt 311, the second metal belt 312 and the third metal belt 313 are arranged side by side and at intervals;

[0114] The first metal strip 311 and the second metal strip 312 are both in the shape of long strips and extend in the same direction. The length of the first metal strip 311 is greater than the length of the second metal strip 312.

[0115] The third metal belt 313 is J-shaped, and the end of the J-shaped belt extends to one side of the second metal belt 312, and there is a gap between the first end of the second metal belt 312. In this article, the length of the first metal belt 311 is the same as the length of the J-shaped end, the gap and the second metal belt 312.

[0116] As the spring 4 moves, the contact segment 31 contacts or disconnects with the spring 4, and the contact segment 31 is located at different positions of the busbar 3. When the contact segments 31 located at different positions contact with the spring 4, the contact segment 31, the conductive segment 32 and the spring 4 form a loop to trigger different electrical signals.

[0117] like Figure 5 The conductive segment schematic diagram shown in the figure, the conductive segment 32 includes a first resistor 321, a second resistor 322, a third resistor 323, a first rail 324, a second rail 325, a third rail 326, a fourth rail 327, a wiring assembly 328, a first port 329 and a second port 3210;

[0118] One end of each of the first electric track 324 and the second electric track 325 is connected to the first metal strip 311;

[0119] The other end of the first power rail 324 is connected to the first port 329;

[0120] The second electric rail 325 is connected to one end of the first resistor 321, and the other end of the first resistor 321 is connected to one end of the wiring assembly 328;

[0121] One end of the third electric rail 326 is connected to the second metal strip 312 , the other end of the third electric rail 326 is connected to one end of the second resistor 322 , and the other end of the second resistor 322 is connected to one end of the wiring assembly 328 ;

[0122] One end of the fourth electric rail 327 is connected to the third metal strip 313 , the other end of the fourth electric rail 327 is connected to one end of the third resistor 323 , and the other end of the third resistor 323 is connected to one end of the wiring assembly 328 ;

[0123] The other end of the wiring assembly 328 is connected to the second port 3210;

[0124] The second port 3210 is used to output electrical signals.

[0125] like Figure 4 The first schematic diagram of the process of the spring piece 4 contacting the busbar 3 is shown. As an embodiment of the present invention, one side of the spring piece 4 is fixed to the locking rod 2, and the other side is provided with at least two branches of the spring piece 4;

[0126] One branch of the spring piece 4 keeps contact with the first metal band 311 when following the reciprocating motion of the locking rod 2; the other branch of the spring piece 4 keeps contact with the J-shaped end of the second metal band 312 or the third metal band 313 when following the reciprocating motion of the locking rod 2, triggering different electrical signals.

[0127] like Figure 6 The contact segment region decomposition schematic diagram shown in FIG. 3 shows that, for the convenience of explanation, the contact segment 31 can be divided into three regions, and the contact segment 31 includes a first region 314 , a second region 315 , and a third region 316 ;

[0128] When the spring 4 contacts the first region 314 , the loop formed by the first electric rail 324 , the second electric rail 325 and the first resistor 321 is connected in parallel with the loop formed by the fourth electric rail 327 and the third resistor 323 .

[0129] For example, in this document, the first resistor 321 may be 10 kΩ, the second resistor 322 may be 2 kΩ, and the third resistor 323 may be 20 kΩ.

[0130] When the lock bar 2 is in the retracted state, the spring 4 is in the first area 314 of the contact section 31. At this time, the left branch of the two branches of the spring 4 is connected to the third metal strip 313, and the right branch is connected to the first metal strip 311. At this time, the current passes through the first port 329, the first rail 324, the second rail 325, the first resistor 321, the wiring assembly 328 and the second port 3210 to form a loop. In addition, the current also passes through the first port 329, the first rail 324, the first metal strip 311, the right branch, the left branch, the third metal strip 313, the fourth rail 327, the third resistor 323, the wiring assembly 328 and the second port 3210 to form a loop. At this time, the first resistor 321 and the third resistor 323 are connected in parallel, and the second resistor 322 is disconnected. At this time, the total resistance of the loop is 7kΩ.

[0131] When the lock bar 2 is in motion, such as retracting or extending, the spring 4 contacts the second area 315, and the first electric track 324, the second electric track 325 and the first resistor 321 form a loop. At this time, the left branch of the two branches of the spring 4 is in the gap, and the right branch is connected to the first metal band 311.

[0132] At this time, the current passes through the first port 329, the first rail 324, the second rail 325, the first resistor 321, the wiring assembly 328 and the second port 3210 to form a loop.

[0133] In the current loop, only the first resistor 321 works, and the second resistor 322 and the third resistor 323 are short-circuited. At this time, the total resistance of the loop is 10 kΩ.

[0134] When the lock bar 2 is in the locked state, the spring 4 contacts the third area 316, and the loop consisting of the first electric rail 324, the second electric rail 325 and the first resistor 321 is connected in parallel with the loop consisting of the third electric rail 326 and the second resistor 322. At this time, the left branch of the two branches of the spring 4 is connected to the second metal strip 312, and the right branch is connected to the first metal strip 311.

[0135] At this time, the current passes through the first port 329, the first rail 324, the second rail 325, the first resistor 321, the wiring assembly 328 and the second port 3210 to form a loop. In addition, the current also passes through the first port 329, the first rail 324, the first metal strip 311, the right branch, the left branch, the second metal strip 312, the third rail 326, the second resistor 322, the wiring assembly 328 and the second port 3210 to form a loop. At this time, the first resistor 321 and the second resistor 322 are connected in parallel, and the third resistor 323 is disconnected. At this time, the total resistance of the loop is 1.6 kΩ.

[0136] In summary, when the spring 4 moves from top to bottom, the total resistance of the loop is 7 kΩ, 10 kΩ and 1.6 kΩ respectively. In this way, the second port 3210 can output different electrical signals to indicate the state of the locking rod 2.

[0137] like Figure 7 The driving mechanism schematic diagram shown in the figure is an embodiment of the present invention, wherein the driving mechanism 1 comprises a driving motor 11, a reduction gear 12 and a transmission gear 13;

[0138] The driving motor 11 is meshed with the reduction gear 12, and the reduction gear 12 is meshed with one side of the transmission gear 13;

[0139] The other side of the transmission gear 13 is movably connected to the lock rod 2 via a linkage shaft 132 . When the driving motor 11 is running, the transmission gear 13 is driven by the reduction gear 12 to move the lock rod 2 .

[0140] In this article, the transmission gear 13 is a half gear structure, one side of the transmission gear 13 having teeth meshes with the reduction gear 12, and the other side of the transmission gear 13 is axially penetrated by a linkage shaft 132; the transmission gear 13 is penetrated by a transmission shaft 131.

[0141] The linkage shaft 132 extends into the locking rod 2 and is movably connected to the locking rod 2 .

[0142] like Figure 8 As shown in the schematic diagram of the self-unlocking mechanism, in some cases, if the drive motor 11 cannot be driven, the user can manually unlock the lock rod 2, so the embodiment of this invention also includes a self-unlocking mechanism;

[0143] The self-unlocking mechanism includes a manual rotating shaft 51, a first manual gear 52 and a second manual gear 53;

[0144] The manual rotating shaft 51 passes through the first manual gear 52 and is fixedly connected thereto;

[0145] The first manual gear 52 is meshed with the second manual gear 53;

[0146] A transmission shaft 131 is passed through the second manual gear 53 . One side of the transmission shaft 131 extends through the transmission gear 13 and is fixedly connected to the transmission gear 13 .

[0147] When the user rotates the manual shaft 51, the first manual gear 52 is driven to rotate. After the rotation, the first manual gear 52 can drive the second manual gear 53 to rotate. The linkage shaft 132 in the second manual gear 53 and the linkage shaft 132 in the transmission gear 13 are the same shaft. Therefore, when the second manual gear 53 rotates, the linkage shaft 132 can output torque to the transmission gear 13, causing the transmission gear 13 to rotate, thereby driving the locking rod 2 to reciprocate up and down.

[0148] In order to make manual unlocking more convenient and labor-saving for the user, the manual rotating shaft 51 described in this article includes a first shaft section and a second shaft section, and the diameter of the first shaft section is greater than the diameter of the second shaft section;

[0149] The surface of the first shaft section is provided with anti-slip grooves 511 , and the second shaft section is fixedly connected to the first manual gear 52 .

[0150] The busbar 3 can be arranged below the locking rod 2 and the driving mechanism 1. Specifically, when the detection device of this article is orthographically projected, a projection range is obtained. In order to reduce the size, the busbar 3 can be arranged within the projection range of the driving mechanism 1.

[0151] In order to reduce the noise when the locking rod 2 moves, the transmission gear 13 and the reduction gear 12 in this article can be helical gears.

[0152] In order to reduce the space occupied by the busbar and thus reduce the volume of the lock, the busbar 3 is arranged on the driving mechanism 1 within the projection range from directly above to directly below with the moving direction of the locking rod 2 as a reference.

[0153] As an embodiment of this invention, this invention also provides a locker, wherein the locker is provided with any one of the locker state detection devices described.

[0154] As an embodiment of this article, this article also provides a new energy vehicle, and the new energy vehicle is provided with the above-mentioned locking device.
