[0042] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0043] like Figures 1 to 3 As shown, point A shown in the figure is the rotation center of the door and the body, the dotted circle shown in the figure is the virtual circular path where the end of the fixed plate is located in different rotation states of the door, the angle α shown in the figure is the minimum limit angle of the limit rod, the angle β shown in the figure is the adjustable limit angle of the limit rod, and the sum of the angles α and β shown in the figure is the maximum limit angle of the limit rod.

[0044] The embodiment of the first aspect of the present invention provides a vehicle door limiting device, which includes a connecting seat 1, a limiting rod 2 and a locking mechanism 3. The connecting seat 1 includes a fixed plate 11 and a rotating plate 12 that are rotatably connected to each other. The fixed plate 11 can be fixedly set on the vehicle door, and the rotating plate 12 is provided with a sleeve 13. The limiting rod 2 passes through and extends out of the sleeve 13, and the limiting rod 2 is slidably connected to the sleeve 13. The limiting rod 2 can be selectively connected to or separated from the vehicle body, that is, the sleeve 13 can be sleeved on the limiting rod 2 and can slide relative to the limiting rod 2. The sleeve 13 can provide sliding guidance and support protection for the limiting rod 2. The limiting rod 2 slides relative to the sleeve 13, which can change the effective limiting length of the limiting rod 2 between the connecting seat 1 and the vehicle body, thereby changing the limiting angle of the vehicle door limiting device to the vehicle door and the vehicle body. The locking mechanism 3 includes a drive assembly 31 and a clamping plate 32, which are connected to each other. The clamping plate 32 is slidably mounted on the rotating plate 12. The sliding direction of the clamping plate 32 intersects the sliding direction of the limit rod 2, so that the clamping plate 32 can apply force to the limit rod 2. Driven by the drive assembly 31, the clamping plate 32 slides to lock or release the limit rod 2.

[0045] With this arrangement, the fixing plate 11 can be fixedly mounted on the vehicle door, and the connection point on the vehicle body can be connected to the limit rod 2. During use, the clamping plate 32 can lock and fix the limit rod 2 through a detachable method such as abutment, clamping, or magnetic attraction, so that the limit rod 2 limits the vehicle door and vehicle body at a preset limit angle. When the opening angle of the vehicle door needs to be increased or decreased for adjustment, the drive assembly 31 can drive the clamping plate 32 to slide and release the limit rod 2. The limit rod 2 can slide relative to the sleeve 13 to the desired limit position. The drive assembly 31 then drives the clamping plate 32 to slide back to lock the limit rod 2, and the door can be adjusted to the desired limit angle. The door limit device adjusts the relative position between the limit rod 2 and the rotating plate 12 and locks it through the locking mechanism 3, and can flexibly adjust the effective limit length of the limit rod 2 to increase or decrease the limit angle of the door by the door limit device, so that the door can be limited and fixed at multiple limit angles. Moreover, the fixed plate 11 can rotate relative to the rotating plate 12, and the limit rod 2 can reserve a longer adjustment length at the position of the sleeve 13, which can effectively increase the rotatable angle of the door, facilitate the door to avoid external objects at the extreme position, reduce the collision between the door or the car body and external objects, and solve the problem in the related art that the door limit device has a single limit angle and the door or the car body is prone to collision with external objects.

[0046] For example, taking the preset limit angle of 90° as an example, the limit rod 2 is passed through and extends out of the sleeve 13 to form a reserved adjustment rod section. When shipping lengthened or enlarged goods, the drive assembly 31 can drive the card plate 32 to slide and release the limit rod 2. The limit rod 2 can slide in the direction away from the vehicle door. The effective limit angle of the limit rod 2 between the sleeve 13 and the vehicle body is increased, and the vehicle door can also rotate relative to the limit rod 2 by utilizing the relative rotation between the fixed plate 11 and the rotating plate 12. The limit angle of the vehicle door relative to the vehicle door can be increased to an angle greater than 90°, for example, 91° to 140°.

[0047] In this embodiment, the length of the sleeve 13 can be equal to or less than the length of the connecting base 1, as long as it can provide guidance and support for the limiting rod 2. The connection point on the vehicle body can be, but is not limited to, a hook, a magnetic block, or an adhesive block, as long as it can be removably connected and fixed to the limiting rod 2. The fixing plate 11 can be a single angle plate structure, or a combination of an angle plate and a flat plate structure, as long as it can be connected and fixed to the vehicle door.

[0048] like Figures 1 to 3As shown, in some embodiments, the limiting rod 2 is a ring-shaped rod 3111 with a fracture, and the limiting rod 2 forms a first end and a second end at the fracture. The number of sleeves 13 is at least two, and the first and second ends of the limiting rod 2 are respectively arranged on both sides of the driving assembly 31, and the first and second ends of the limiting rod 2 are respectively slidably connected to the sleeve 13. In this configuration, the limiting rod 2 is designed as a ring-shaped rod 3111, and the annular hole formed by it has a large aperture, which facilitates rapid hooking or clamping with the connection point on the vehicle body, reducing the possibility of accidental failure of the limiting rod 2. In addition, multiple sleeves are provided and are respectively provided for sliding connection of the ends of the limiting rod 2, which can form multiple adjustment points, facilitate force distribution, and avoid stress concentration damage at the connection point between the limiting rod 2 and the sleeve 13.

[0049] In this embodiment, the limiting rod 2 can be a rigid rod 3111 or a flexible rod 3111, as long as it can limit the opening angle of the vehicle door. When the limiting rod 2 is a flexible rod 3111, the sliding position of the first end of the limiting rod 2 relative to the sleeve 13 and the sliding position of the second end of the limiting rod 2 relative to the sleeve 13 can be the same or different. For example, the sliding length of the first end of the limiting rod 2 relative to the sleeve 13 can be 1 cm, and the sliding length of the second end of the limiting rod 2 relative to the sleeve 13 can be 2 cm. The effective limiting length of the limiting rod 2 as a whole can vary by 1.5 cm. The first and second ends of the limiting rod 2 can move in coordination with each other to form a variety of effective limiting lengths, providing flexible and diverse adjustment methods.

[0050] like Figures 2 to 4 As shown, in some embodiments, a first limiting portion 21 is provided on the limiting rod 2, and the first limiting portion 21 is provided at the first end and the second end of the limiting rod 2, that is, the first limiting portion 21 can limit the minimum length of the limiting rod 2 penetrating into the sleeve 13 at the first end and the second end of the limiting rod 2, thereby preventing the door from opening at an excessively large angle and causing excessive rotation, causing damage to the connection between the door and the vehicle body, and also preventing the limiting rod 2 from being separated from the sleeve 13.

[0051] Among them, the first limiting portion 21 can be a flange or a pin structure. The size of the first limiting portion 21 is larger than the radial size of the sleeve 13, and can limit the minimum length of the limiting rod 2 penetrating into the sleeve 13 to prevent the limiting rod 2 from escaping from the sleeve 13.

[0052] In some embodiments, the limiting rod 2 is provided with a second limiting portion 22. The second limiting portion 22 is provided at a position on the limiting rod 2 away from the first and second ends. That is, the second limiting portion 22 maintains a certain distance from the first and second ends of the limiting rod 2 to facilitate the formation of sliding space between the limiting rod 2 and the sleeve 13. The second limiting portion 22 can limit the maximum length of the limiting rod 2 inserted into the sleeve 13 at a position away from the first and second ends of the limiting rod 2, thereby preventing damage to the door from colliding with cargo or the vehicle body due to an excessively small door opening angle. The slidable adjustable length of the limiting rod 2 is the length between the first limiting portion 21 and the second limiting portion 22 along the axial direction of the limiting rod 2 minus the axial length of the sleeve 13. By presetting the relative positions of the first limiting portion 21 and the second limiting portion 22, the slidable adjustable length of the limiting rod 2 relative to the sleeve 13 can be preset.

[0053] The second limiting portion 22 may be a shoulder structure or a snap ring structure. The radial dimension of the second limiting portion 22 is larger than the radial dimension of the sleeve 13 , and can limit the maximum length of the limiting rod 2 penetrating into the sleeve 13 .

[0054] like Figures 4 to 6 As shown, in some embodiments, the clamping plate 32 includes a supporting portion 321 and a clamping portion 322. The supporting portion 321 is provided on the rotating plate 12 and is in transmission connection with the driving assembly 31. The clamping portion 322 is fixedly provided on the supporting portion 321. The limiting rod 2 is provided with a plurality of clamping slots 23. The clamping portion 322 can be clamped and locked with the clamping slots 23. In this configuration, the clamping portion 322 can lock the limiting rod 2 by clamping with the clamping slots 23. The driving assembly 31 drives the supporting portion 321 to move, and the supporting portion 321 drives the clamping portion 322 to slide out of the clamping slots 23, thereby releasing the limiting rod 2 from the clamping plate 32.

[0055] In this embodiment, when the limiting rod 2 is a ring-shaped rod 3111, the rod sections where the first end and the second end of the limiting rod 2 are located can be provided with multiple card slots 23, and the clamping portion 322 of the clamping plate 32 can cooperate with the card slots 23 on the first end and the second end of the limiting rod 2, which can increase the connection and fitting area and disperse the force between the clamping plate 32 and the limiting rod 2.

[0056] When the locking cam 322 is unlocked, the locking cam 323 is unlocked and the locking cam 322 is unlocked, so that the locking cam 322 can be unlocked and the locking cam 322 can be unlocked.

[0057] In this embodiment, the sliding portion 323 and the clamping portion 322 can both be folding plate structures located on different sides of the supporting portion 321 , and the length of the folding plate structure is equal to or greater than the length of the limiting rod 2 .

[0058] like Figures 4 to 6 As shown, in some embodiments, the drive assembly 31 includes a button 311 and an elastic member 312. The button 311 is disposed on the card plate 32 and the rotating plate 12. The button 311 is provided with an anti-slip portion 3112. The anti-slip portion 3112 is pressed against the card plate 32. The anti-slip portion 3112 can push the card plate 32 toward the limit rod 2 and engage and lock with the limit rod 2. The elastic member 312 is disposed between the button 311 and the rotating plate 12 and is configured to provide a force for the anti-slip portion 3112 to press against the card plate 32 so that the card plate 32 is locked with the limit rod 2.

[0059] With this arrangement, when the clamping plate 32 locks the limiting rod 2, the end of the button 311 is held in a predetermined position relative to the rotating plate 12 by the elastic force of the elastic member 312, so that the anti-slip portion 3112 compresses the clamping plate 32, and the engaging portion 322 of the clamping plate 32 squeezes the limiting rod 2, maintaining the locking state between the engaging portion 322 and the limiting rod 2. When the clamping plate 32 needs to release the limiting rod 2, an external force is applied to the button 311. This force overcomes the elastic force of the elastic member 312, causing the button 311 to move relative to the rotating plate 12. The squeezing effect of the anti-slip portion 3112 on the clamping plate 32 disappears, and the engaging portion 322 of the clamping plate 32 can be separated from the limiting rod 2. The limiting rod 2 can then slide freely relative to the sleeve 13 to a desired position, thereby adjusting the effective limiting length of the limiting rod 2 and, consequently, the limiting angle of the door limiting device. After it is in place, it is only necessary to remove the external force, and the elastic member 312 needs to restore its deformation. The elastic member 312 drives the button 311 to move relative to the rotating plate 12, so that the anti-slip portion 3112 re-extrudes the card plate 32, so that the clamping portion 322 of the card plate 32 can squeeze the limit rod 2, and the clamping portion 322 and the limit rod 2 are locked again. The structure is simple and easy to use.

[0060] In this embodiment, the button 311 and the card plate 32 can be slidably connected, and there is a certain movable space between the card plate 32 and the anti-slip portion 3112. The button 311 drives the anti-slip portion 3112 to move, and the anti-slip portion 3112 can squeeze the card plate 32, thereby pushing the card plate 32 to lock with the limit rod 2. Alternatively, the anti-slip portion 3112 of the button 311 and the card plate 32 can be fixedly connected, such as by bolts, magnetic connection, or adhesion. When the button 311 drives the anti-slip portion 3112 to move, the card plate 32 can move synchronously with the anti-slip portion 3112, which also facilitates the anti-slip portion 3112 to drive the card plate 32 to lock with the limit rod 2.

[0061] The elastic member 312 may be, but is not limited to, a spring or a tube or gasket made of elastic material, and can drive the button 311 to return to its original position after the button 311 is pressed.

[0062] like Figures 4 to 6 As shown, in some embodiments, the button 311 includes a detachably connected rod 3111 and a cap 3113, the rod 3111 is passed through the card plate 32 and the rotating plate 12, the anti-slip portion 3112 is provided on the rod 3111, the cap 3113 and the anti-slip portion 3112 are respectively provided on both sides of the combination of the card plate 32 and the rotating plate 12, the elastic member 312 is sleeved on the rod 3111, and the elastic member 312 is located between the rotating plate 12 and the cap 3113. During installation, after the rod 3111 passes through the rotating plate 12, the elastic member 312 can be sleeved and connected to the cap 3113, thereby realizing the installation of the button 311 on the rotating plate 12, which is convenient for installation. The cap 3113 and the rotating plate 12 can clamp and limit the elastic member 312, and the rod 3111 can guide the elastic member 312 to facilitate the accuracy of the elastic action of the elastic member 312 on the rod 3111, thereby ensuring the locking stability of the limit rod 2 by the clamping plate 32.

[0063] like Figures 4 to 6 As shown, in some embodiments, a rotating shaft 14 is provided between the fixed plate 11 and the rotating plate 12, and a torsion spring 15 is sleeved on the rotating shaft 14, one end of the torsion spring 15 is fixedly provided on the fixed plate 11, and the other end of the torsion spring 15 is fixedly provided on the rotating plate 12, so that the fixed plate 11 and the rotating plate 12 have a certain rotation buffer space in the rotation direction, which not only can elastically limit the relative rotation position of the fixed plate 11 and the rotating plate 12, but also can enable the fixed plate 11 to return to its original position in time under the elastic action of the torsion spring 15 after excessive rotation relative to the rotating plate 12, thereby avoiding excessive rotation angles of the fixed plate 11 and the rotating plate 12, causing collision damage therebetween.

[0064] In some embodiments, multiple angle marks are provided on the limit rod 2. The angle marks are used to display the opening angle of the door relative to the vehicle body when the locking mechanism 3 is locked at the corresponding position on the limit rod 2. With this arrangement, the angle marks can be provided for the user to make an intuitive selection reference. The user can predict the angle at which the door needs to be opened relative to the vehicle body based on the usage conditions, and then directly find the corresponding angle mark on the limit rod 2 and lock the locking mechanism 3 at the corresponding position of the limit rod 2, which is more convenient to use.

[0065] In this embodiment, the angle marks may be arranged at intervals along the length direction of the limiting rod 2, and the angle marks may be, but are not limited to, patterns, numbers, or scale lines.

[0066] like Figures 1 to 3 As shown, an embodiment of the second aspect of the present invention provides a vehicle, including a door limit device in any of the above-mentioned schemes, the vehicle includes a door and a body that are rotatably connected, and the door limit device is arranged between the door and the body, which can effectively increase the rotatable angle of the door, facilitate the door to avoid external objects at the extreme position, and reduce the collision between the door or the body and external objects.

[0067] Since the vehicle includes the door limiting device described above, the vehicle of the embodiment of the present invention has all the advantages and beneficial effects of the above embodiments, which will not be described in detail here.

[0068] In some embodiments, the connection point on the vehicle body can be, but is not limited to, a hook, a magnetic block, or an adhesive block, which can be detachably connected and fixed to the limit rod 2. A guide plate 4 is also provided on the vehicle body. The guide plate 4 is provided at the connection point. The guide plate 4 is a curved plate and can be provided along the movement path of the limit rod 2 to guide the connection operation between the limit rod 2 and the connection point.

[0069] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
