[0038] In automobile assembly, the limit device installed on the front hood of the vehicle is an automobile component. Its main function is to ensure that the front hood of the vehicle can remain on a predetermined motion trajectory during the opening and closing process, and to prevent the movement of the hood beyond the expected range from causing collision or damage with other parts of the vehicle body. It is found in the existing limit device that when the connector of the existing automobile front hood mounting limit device is inserted into the interior of the front hood mounting frame 421, one side will produce severe friction with the guide block, which is easy to cause wear after long-term use, thereby causing the problem of the front hood shaking.

[0039] The present invention provides a limiting device.

[0040] See also Figures 1 to 8 In one embodiment of the present invention, the limiting device is used for the front hood of a vehicle, and the limiting device 100 includes a connector 1, a mounting member 2 and a limiting structure 3; the connector 1 has two end faces along its length direction, and at least one end face is set as a first end face 11; the mounting member 2 has an outer side facing the first end face 11, and a plug-in end 21 is provided on its outer side for plugging with the first end face 11 of the connector 1; and the limiting structure 3 includes at least one limiting portion 31, and the limiting portion 31 is provided on the mounting member 2 for limiting the plugging of the connector 1.

[0041] The technical solution of the present invention adopts the limiting structure 3 and utilizes the setting of the limiting portion 31, so that when the connector 1 is plugged into the mounting member 2 through the plug end 21, the limiting portion 31 can limit the plugging of the connector 1. This can effectively prevent the side edges of the connector 1 from being worn after long-term use, prevent the subsequent front cover from shaking during use, and improve stability.

[0042] In this embodiment, there is no specific restriction on the number of the limiting portions 31. In order to better avoid wear on the side positions of the connector 1, preferably, two limiting portions 31 are provided to better protect the two sides of the connector 1. For the specific setting method, please refer to the following description.

[0043] The installation part 2 can be set up in the form of a mounting bracket, a mounting shell, etc.; considering that the connector 1 needs to be plugged into the interior of the installation part 2, in this embodiment, the installation part 2 is set as a mounting shell, and the interior of the mounting shell has a accommodating cavity for the placement of the limiting structure 3.

[0044] Furthermore, in order to achieve the purpose of anti-wear, as Figure 3As shown, in the technical solution of the present invention, the limiting portion 31 includes a mounting slot 311, a transmission arm 312, a limiting roller 313 and a spring 314; wherein the mounting slot 311 is opened on one side of the connector 1 along its length direction and is connected to the plug end 21, the transmission arm 312 is rotatably installed in the mounting slot 311, the limiting roller 313 is connected to the side of the transmission arm 312 located in the mounting slot 311, one end of the spring 314 is connected to the side of the transmission arm 312 away from the limiting roller 313, and the other end is connected to the inner wall of the mounting slot 311; in this way, through the setting of the spring 314, the connector 1 can be limited by squeezing the limiting roller 313 when the connector 1 is plugged in. At the same time, when the connector 1 is plugged in and squeezed, the transmission arm 312 is provided with a reset tension to ensure that the limiting roller 313 can accurately return to the predetermined position when not squeezed.

[0045] It should be explained that the connection between the limiting roller 313 and the transmission arm 312 is a movable installation, that is, when the connector 1 abuts against the limiting roller 313, the limiting roller 313 can rotate on the transmission arm 312.

[0046] The spring 314 is installed in a fixed manner, that is, both ends of the spring 314 are fixedly connected to a side of the transmission arm 312 away from the limiting roller 313 and an inner wall of the installation slot 311 respectively.

[0047] It should be noted that, in this embodiment, there are two limiting portions 31 , which are symmetrically arranged on both sides of the plug end 21 along its length direction, thereby protecting both sides of the plug connector 1 .

[0048] Furthermore, in order to achieve a smooth plug-in effect, as Figure 6 As shown, in the technical solution of the present invention, the connector 1 has two inclined surfaces 12 along its width direction, and the inclined surfaces 12 abut against the outer peripheral wall of the limiting roller 313; in this way, when the connector 1 is plugged into the plug end 21, the inclined surfaces 12 first squeeze the limiting roller 313, so that the force is evenly distributed during plugging, thereby better protecting the two sides of the connector 1 and avoiding damage.

[0049] It should be supplemented that a keyhole is provided inside the connector 1 on one side close to the plug end 21 , wherein the keyhole is used to cooperate with a lock body inside the engine compartment to achieve the purpose of locking the connector 1 .

[0050] It should be added that two first connecting ears are fixedly installed at the bottom of both sides of the mounting part 2 along its thickness direction, and two second connecting ears are fixedly installed above the four first connecting ears. Threaded holes are provided inside the first connecting ears and the second connecting ears. Therefore, through the setting of the threaded holes, the first mounting ears and the second mounting ears can be fixedly installed inside the engine compartment to achieve the purpose of installation and use.

[0051] Furthermore, considering that the transmission arm 312 is rotatable, when the limiting roller 313 is pressed, the transmission arm 312 will be displaced. In order to avoid the movement of the transmission arm 312 being restricted, as shown in FIG. Figure 2 As shown, in the technical solution of the present invention, the limiting structure 3 also includes a connecting arm 32, a connecting rod 33, a guide sleeve 34 and a movable rod 35; wherein, the connecting arm 32 is connected to the side of the two transmission arms 312 away from the limiting roller 313 on one side along the length direction thereof, the end of the spring 314 away from the mounting groove 311 is connected to the outer peripheral wall of the connecting arm 32, the guide sleeve 34 is fixed on the inner wall of the mounting groove 311, and the movable rod 35 is passed through the guide sleeve 34 on one side along the length direction thereof and is slidably connected to the inner wall of the guide sleeve 34, and the two ends of the connecting rod 33 are respectively connected to the movable The movable rod 35 is hinged at one end away from the guide sleeve 34 and at the side of the connecting arm 32 away from the transmission arm 312; in this way, when the transmission arm 312 rotates, it can drive the connecting arm 32 to stretch, thereby pulling the connecting rod 33 to move, and driving the movable rod 35 to move in the guide sleeve 34, wherein the setting of the guide sleeve 34 has a guiding and limiting effect on the movable rod 35, and the problem of limited movement of the transmission arm 312 is avoided by the displacement of the movable rod 35, thereby improving the flexibility of the transmission arm 312, and further making better use of the limiting roller 313 to limit the connector 1.

[0052] It should be supplemented that the connection arm 32 may be arranged in an L-shape, which is beneficial to the force conversion of the transmission arm 312 .

[0053] Furthermore, considering that the setting of a single limiting roller 313 may not achieve a better limiting effect, thereby reducing the anti-wear effect, such as Figure 3As shown, in the technical solution of the present invention, the limiting structure 3 also includes an abutment roller 36, which is rotatably installed on the side of the guide sleeve 34 away from the connecting rod 33, and the outer peripheral wall of the abutment roller 36 abuts against the outer peripheral wall of the connector 1; in this way, through the setting of the abutment roller 36, it plays a role of abutting the outer peripheral wall of the connector 1, and cooperates with the limiting roller 313 to achieve the purpose of two-level limiting, so that the connector 1 is in the preset position inside the mounting member 2, which can effectively avoid the wear of both sides of the connector 1 after long-term use, avoid the shaking of the front cover during use, and improve the service life of the front cover.

[0054] Of course, in order to further limit the position of the connector 1 so that the connector 1 can be accurately inserted into the mounting member 2, in the technical solution of the present invention, the limiting structure 3 also includes mounting rollers 37, and the mounting rollers 37 are provided on both sides of the plug-in end 21 along its thickness direction, and the outer surfaces of the two mounting rollers 37 abut against the outer peripheral wall of the connector 1; in this way, through the setting of the mounting rollers 37, the connector 1 is limited when it is plugged in, so that the connector 1 can be directly and accurately inserted into the interior of the mounting member 2 when it is plugged in, thereby reducing unnecessary friction with the mounting member 2 and further preventing the connector 1 from being worn.

[0055] In addition, in order to achieve the purpose of being able to reset the connector 1 after use, in the technical solution of the present invention, the limiting device 100 also includes a reset structure 4, which is used to reset the connector 1 after it is separated from the mounting member 2, so that the connector 1 can remain in its initial position after being separated from the mounting member 2.

[0056] Specifically, the reset structure 4 includes a mounting shell 41 and a reset assembly 42, which are arranged on the side of the plug-in component 1 away from the first end face 11, and an accommodating space is formed inside the mounting shell 41; and the reset assembly 42 is arranged in the accommodating space; wherein, the reset assembly 42 includes a mounting frame 421, a reset plate 422 and an elastic member 423, the mounting frame 421 is arranged in the accommodating space, the reset plate 422 is arranged on the side of the plug-in component 1 away from the first end face 11, the mounting frame 421 contacts the reset plate 422, the mounting shell 41 is sleeved on the outer surface of the reset plate 422, and the two ends of the elastic member 423 are respectively connected to the inner wall of the mounting shell 41 and the side of the mounting frame 421 away from the reset plate 422; in this way, through the arrangement of the elastic member 423, a downward elastic force can be applied to the mounting frame 421, thereby squeezing the reset plate 422, thereby achieving the purpose of resetting the plug-in component 1 in the mounting shell 41.

[0057] It should be added that two third connecting ears are fixedly installed on the side of the installation shell 41 away from the plug-in, and fixing holes are opened inside the two third connecting ears, through which the third connecting ears can be fixed to the bottom of the front cover.

[0058] In this embodiment, there is no specific restriction on the arrangement of the elastic member 423. For example, it can be a tension spring. Specifically, the two ends of the tension spring are respectively fixed to the side of the mounting frame 421 away from the reset plate 422 and the inner wall of the accommodating space.

[0059] The mounting bracket 421 is movably installed in the accommodating space, and the reset plate 422 is fixed to a side of the connector 1 away from the first end surface 11 .

[0060] Of course, in this embodiment, there is no specific limitation on the number of the elastic members 423 . Considering the force balance, two elastic members 423 can be provided in parallel along the length direction of the mounting bracket 421 .

[0061] It should be noted that an avoidance hole is opened on the outer peripheral wall of the mounting shell 41, and the end of the connector 1 away from the first end face 11 passes through the avoidance hole and extends to connect with the reset plate 422 in the accommodating space, so that the connector 1 has a certain amount of movement space when inserted into the mounting member 2.

[0062] It needs to be explained that the side of the reset plate 422 close to the mounting bracket 421 is set to be arc-shaped, and the side of the mounting bracket 421 close to the reset plate 422 is set to be arc-shaped, which is adapted to the reset plate 422, and can facilitate the movement between the mounting bracket 421 and the reset plate 422, thereby providing movement space for the connector 1.

[0063] Furthermore, in order to achieve the purpose of guiding and limiting the mounting frame 421, the connector 1 can be reset more accurately. Figure 5 As shown, in the technical solution of the present invention, the reset structure 4 also includes a limiting member 43, and the limiting member 43 includes a limiting rod 431 and a limiting through hole 432. The limiting through hole 432 is opened on the side of the mounting frame 421 away from the reset plate 422, and the limiting rod 431 is inserted into the inside of the limiting through hole 432; in this way, through the setting of the limiting through hole 432 and the limiting rod 431, the mounting frame 421 is restricted in the accommodating space, and the mounting frame 421 is guided and limited.

[0064] It should be supplemented that one end of the limiting rod 431 away from the limiting through hole 432 is fixed to the inner wall of the accommodating space.

[0065] It should be noted that, in this embodiment, there is no specific restriction on the number of the limiting members 43 . For example, the number of the limiting holes and the limiting columns may be three, thereby achieving a better guiding and limiting effect on the mounting frame 421 .

[0066] In addition, in order to make the connector 1 reset smoothly, Figure 4 As shown, in the technical solution of the present invention, the reset structure 4 also includes a reset roller 44, which is provided on the side of the mounting frame 421 close to the reset plate 422 and abuts against the outer peripheral wall of the reset plate 422; in this way, through the setting of the reset roller 44, it can abut and squeeze with the arc groove set on the reset plate 422, thereby driving the arc groove to reset, thereby driving the connector 1 to reset.

[0067] The reset roller 44 is rotatably connected to the mounting bracket 421 , which is beneficial for the rotation of the reset roller 44 .

[0068] It should be added that a plurality of oil grooves are provided on the side of the reset plate 422 away from the mounting frame 421. In this embodiment, the number of the oil grooves is set to three, and the interior of the oil grooves is used to apply grease, so that the reset plate 422 and the mounting shell 41 can maintain lubrication for a long time, thereby improving the reset success rate.

[0069] The present invention also proposes a method for installing a limiting device on a front hood of a vehicle: when the connector 1 is inserted into the interior of the mounting member 2, the mounting roller 37 is used to limit the connector 1, so that the connector 1 can be accurately inserted into the interior of the mounting member 2 and reduce the friction between the connector 1 and the mounting member 2. Through the arrangement of the avoidance hole and the reset plate 422, the reset plate 422 is slidably connected to the interior of the mounting shell 41, so that the connector 1 can have a certain degree of freedom when inserted into the interior of the mounting member 2. The movable space ensures that the connector 1 can be smoothly inserted into the interior of the mounting member 2. When the inclined surface 12 of the connector 1 contacts the abutment roller 36, the abutment roller 36 and the transmission arm 312 rotate in the direction away from the connector 1. That is, the connecting arm 32 is driven to rotate upward by the lever principle, and the movable rod 35 and the abutment roller 36 are driven to move in the direction close to the connector 1 by the connecting rod 33. The abutment roller 36 abuts against both sides of the connector 1 to limit the connector 1.

[0070] When the connector 1 is separated from the mounting member 2, the elastic member 423 applies a downward elastic force to the mounting frame 421 and the reset roller 44, and the reset roller 44 is squeezed by the arc groove on the reset plate 422 to drive the reset plate 422 to reset the connector 1, so that the connector 1 can remain in its initial position after being separated from the mounting member 2.

[0071] The present invention also proposes a vehicle, which includes a vehicle and a limiting device. The specific structure of the limiting device refers to the above-mentioned embodiment. Since this vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
