[0038] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0039] Refer to Figures 1 to 5 , a parking space lock with a simple connector, including a housing 1, a spindle 2, a blocking bar 3 and a connector 4;

[0040] The spindle 2 is rotatably connected to the inside of the housing 1; the spindle 2 is connected to the blocking bar 3 through the connector 4 to achieve linkage; a driving component is provided inside the housing 1 for driving the spindle 2 to rotate, thereby driving the blocking bar 3 to swing;

[0041] Both shaft ends 21 of the spindle 2 extend out of the side wall of the housing 1, the blocking bar 3 has an open frame structure, and both shaft ends 21 are connected to both bar ends 31 of the blocking bar 3 through the connector 4;

[0042] The shaft end 21 is provided with a first radial screw hole 210;

[0043] The bar end 31 of the blocking bar 3 is provided with a first radial through hole 310;

[0044] The connector 4 includes a main part 41, a sub-part 42, a first screw 43, a first bolt 44 and a first nut 45;

[0045] The main part 41 includes a first body 411 and a second body 412;

[0046] The first body 411 is provided with a first cavity 4110 capable of accommodating the shaft end 21, and the shaft end 21 can be inserted into the first cavity 4110;

[0047] The first body 411 is provided with a second radial through hole 4111 communicating with the first cavity 4110;

[0048] The first screw 43 passes through the second radial through hole 4111 and is connected to the first radial screw hole 210;

[0049] The second body 412 is provided with a second cavity 4120;

[0050] The accessory 42 is provided with a third cavity 420;

[0051] The second cavity 4120 and the third cavity 420 form a space capable of accommodating the rod end 31, and the rod end 31 can be assembled into this space;

[0052] The second body 412 is provided with a third radial through hole 4121;

[0053] The accessory 42 is provided with a fourth radial through hole 421;

[0054] The first bolt 44 sequentially passes through the fourth radial through hole 421, the first radial through hole 310 and the third radial through hole 4121, and is connected to the first nut 45.

[0055] Thus, during assembly, first, the first cavity 4110 of the main part 41 is sleeved on the shaft end 21 of the main shaft 2, so that the second radial through hole 4111 is aligned with the first radial screw hole 210. Then, the first screw 43 is passed through the second radial through hole 4111 and screwed into the first radial screw hole 210 to realize the connection between the main shaft 2 and the main part 41;

[0056] Then, the rod end 31 of the barrier rod 3 is placed in the second cavity 4120 of the main part 41, so that the first radial through hole 310 is aligned with the third radial through hole 4121. Then, the accessory 42 is covered on the second cavity 4120, so that the fourth radial through hole 421 is aligned with the first radial through hole 310. Then, the first bolt 44 sequentially passes through the fourth radial through hole 421, the first radial through hole 310 and the third radial through hole 4121, and then the first bolt 44 is connected to the first nut 45 to realize the connection between the barrier rod 3 and the main part 41, thereby realizing the connection between the main shaft 2 and the barrier rod 3.

[0057] Among them, since both shaft ends 21 are connected to the two rod ends 31 of the barrier rod 3 through the connector 4, and the barrier rod 3 is an open frame structure and the two rod ends 31 are symmetrically arranged, the setting of the accessory 42 facilitates the lateral placement of the rod ends 31 in the second cavity 4120.

[0058] It can also be understood that: the main shaft 2 is axially inserted into the first cavity 4110 of the main part 41, and the barrier rod 3 is laterally assembled into the second cavity 4120 of the main part 41, so as to realize the convenient assembly and disassembly of the main shaft 2 and the barrier rod 3. Moreover, the connector 4 has a simple structure, is convenient to manufacture, and is beneficial to cost saving.

[0059] The first body 411 is cylindrical, the second body 412 is semi-cylindrical, the first body 411 and the second body 412 are coaxially arranged, and the accessory 42 is semi-cylindrical.

[0060] The outer diameter dimensions of the first body 411, the second body 412 and the accessory 42 are the same. Thus, after assembly, the connector 4 is cylindrical with a unified outer diameter dimension, improving the aesthetics.

[0061] The cross-section of the shaft end 21 is circular, and the cross-section of the corresponding first cavity 4110 is circular;

[0062] The cross-section of the rod end 31 is circular, the cross-section of the corresponding second cavity 4120 is semi-circular, and the cross-section of the third cavity 420 is semi-circular;

[0063] The first cavity 4110 and the second cavity 4120 are coaxially arranged.

[0064] The second radial through-hole 4111, the third radial through-hole 4121 and the fourth radial through-hole 421 are all counterbore holes. Thus, the first screw 43, the first bolt 44 and the first nut 45 are hidden, reducing the protrusion and improving the aesthetics.

[0065] Reference Figure 6 , a shaft hole 11 is provided on the side wall of the housing 1, a bearing 12 is provided in the shaft hole 11, the main shaft 2 is connected to the bearing 12, and an end cover 13 is provided outside the shaft hole 11. The main shaft 2 rotates smoothly through the bearing 12, and the end cover 13 seals the shaft hole 11, playing a sealing role and limiting the bearing 12.

[0066] Reference Figures 7 to 9 , the parking lock further includes a driving part 5, a transmission part 6 and an anti-collision device 7;

[0067] The driving part 5 is arranged inside the housing 1 and is used to provide the power for the rotation of the main shaft 2;

[0068] The transmission part 6 is arranged inside the housing 1 and transmits the power of the driving part 5 to the main shaft 2. The transmission part 6 includes a first gear 61 and a second gear 62. The pitch circle diameter of the first gear 61 is smaller than that of the second gear 62. The first gear 61 is connected to the driving part 5, and the second gear 62 is connected to the main shaft 2; The driving part 5 drives the rotation of the main shaft 2, thereby driving the swing of the blocking rod 3;

[0069] The anti-collision device 7 includes a torsion spring 71; the torsion spring 71 includes a spiral part 710, a first end 711 and a second end 712; the inner hole of the spiral part 710 is axially sleeved on the main shaft 2 and is located on one side of the second gear 62;

[0070] The first end 711 is fixedly connected to the main shaft 2, and the second end 712 is fixedly connected to the second gear 62.

[0071] Thus, when the blocking rail 3 is impacted or rammed by an external force, due to the existence of the torsion spring 71, it can absorb a certain amount of impact force, play a certain buffering role, reduce the impact on the driving part 5 and / or the transmission part 6, and thus play a role in protecting the driving part 5 and / or the transmission part 6.

[0072] Reference Figure 9 , the first end portion 711 is in a hook shape; the main shaft 2 is provided with a second radial screw hole 23, the second radial screw hole 23 is provided with a second screw 24, and the first end portion 711 hooks the second screw 24.

[0073] The second end portion 712 is in a straight line shape and extends along the axial direction of the spiral portion 710; a socket 621 is provided at the edge portion of the second gear 62, and the second end portion 712 is inserted into the socket 621;

[0074] Thus, a buffer structure for preventing collision is formed between the second gear 62 and the main shaft 2; moreover, the second end portion 712 is connected to the second gear 62 to realize the axial limit of the second gear 62.

[0075] Reference Figure 9 , a snap ring 25 is provided on the side of the second gear 62 away from the torsion spring 71, and the main shaft 2 is provided with an annular groove 22 for assembling the snap ring 25. The snap ring 25 is used to limit the second gear 62. In this way, the cooperation between the snap ring 25 and the second end portion 712 of the torsion spring 71 realizes the axial limit of the second gear 62, simplifies the structure, and saves costs.

[0076] Reference Figure 7 , the driving part 5 includes a motor 51 and a speed reducer 52, and the output end of the speed reducer 52 is connected to the first gear 61.

[0077] The above discloses only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
