Description

Technical Field

[0001] The utility model relates to the technical field of automobile doors, and particularly relates to a door auxiliary lock. In addition, the utility model also relates to a vehicle. Background Technique

[0002] In order to facilitate the entry and exit of personnel or the taking and placing of works, doors are generally provided on the side of the vehicle, and a rear door that opens laterally and hangs a spare tire is also provided at the rear of the vehicle. The side doors generally adopt outward-opening flat doors, and are locked and fixed on the door frame through two hinges on one side and a door lock on the other side. The rear doors mostly adopt upward-opening outward-opening doors or outward-opening flat doors; for off-road vehicles, the spare tire is mostly placed by hanging the spare tire on the rear door. In this case, the rear door generally adopts an outward-opening flat door, and is also locked and fixed on the door frame through two hinges on one side and a door lock on the other side.

[0003] For the rear door with an automobile spare tire hanging on the back, two hinges and a door lock achieve three-point locking and fixing of the rear door on the door frame; however, when the rear door is in the closed state, the hinges and the door lock fix the rear door in a triangular structure. Since there is only one fixed point (door lock connection position) on one side of the door lock (usually the left side, or it can also be the right side), this point to the upper corner of the door frame on the same side is a cantilever structure, and the center of gravity of the rear spare tire is at the rear of the rear door. Under the action of gravity, the rear door will generate a moment of backward outward turning, which will cause the upper left corner of the door body of the rear door to turn outward; especially on bumpy roads, the top of the rear door will repeatedly turn outward and recover, thus generating a slapping noise between the rear door and the door frame.

[0004] In this case, even if an ordinary mechanical lock is added to the upper end of the side-opening rear door on the door lock side, due to the large space occupied by the layout and the difficulty of installation; and the locking position of the ordinary mechanical lock is fixed and cannot adaptively adjust the opening or locking state according to the door state. Content of the Utility Model

[0005] In view of this, the utility model aims to propose a door auxiliary lock to improve the problem of abnormal noise generated by the door shaking relative to the door frame.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] A door auxiliary lock includes a locking member and a locking and cooperating member. One of the locking member and the locking and cooperating member is arranged on the door, and the other is arranged on the corresponding door frame of the door; the locking member includes a base for fixing the locking member, two locking arms oppositely arranged on the base, and a driving mechanism; the locking and cooperating member includes a connecting seat for fixing the locking and cooperating member, and a locking column arranged on the connecting seat.

[0008] The locking post can extend between the two locking arms as the vehicle door closes; the driving mechanism can drive the two locking arms to approach or move away from each other to clamp or release the locking post.

[0009] Furthermore, the base includes a connecting chassis, and two brackets respectively disposed at the top and bottom of the connecting chassis; the two locking arms are respectively slidably disposed on the two brackets, and the driving mechanism drives the two locking arms to move synchronously to complete the approaching or moving away actions.

[0010] Furthermore, each locking arm includes an arm body, and a clamping portion and a stud respectively disposed at both ends of the arm body; elongated pin holes are provided on both of the two brackets, and the stud is slidably disposed in the corresponding pin hole on the bracket; the two clamping portions belonging to the two locking arms are in clamping cooperation with the locking post.

[0011] Furthermore, an arc-shaped clamping surface is formed on the side of the clamping portion facing the locking post, and when the two clamping portions clamp the locking post, the clamping surface is in abutting cooperation with the cylindrical surface of the locking post.

[0012] Furthermore, locking post threads are provided on the cylindrical surface of the locking post, and clamping threads are provided on the clamping surface; when the two clamping portions clamp the locking post, the locking post threads and the clamping threads are meshed and connected.

[0013] Furthermore, the driving mechanism includes a driving motor, and a transmission unit disposed between the driving motor and the two locking arms; in different rotation directions, the driving motor drives the transmission unit to drive the two locking arms to complete the approaching or moving away actions.

[0014] Furthermore, the transmission unit includes a screw rod connected to the power output shaft of the driving motor, and threaded holes with opposite helix directions are respectively formed on the two locking arms; the screw rod is simultaneously screwed into the two threaded holes.

[0015] Furthermore, the screw rod is arranged perpendicular to the locking post, and the axis of the screw rod and the axis of the locking post intersect.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] The door auxiliary lock of the present utility model is provided with two split locking arms on the locking member. Driven by the driving mechanism, the two locking arms can approach or separate to perform a clamping action, so as to clamp and lock the lock post on the locking and cooperating member extending between the two locking arms, enabling flexible locking and detachment between the locking member and the locking and cooperating member. The locking member and the locking and cooperating member are respectively arranged on the vehicle door and the door frame, thereby providing a flexibly detachable and lockable connection point between the vehicle door and the door frame, which helps to improve the problem of abnormal noise generated by the vehicle door shaking relative to the door frame.

[0018] In addition, an arc-shaped clamping surface is provided on the clamping portion of the locking arm, which can increase the clamping contact area between the clamping portion and the lock post, thereby improving the clamping force between the two and making the locking connection between the locking member and the locking and cooperating member more stable and reliable.

[0019] Furthermore, the driving mechanism adopts a motor-driven form, which is convenient to control and has flexible response. Through the forward and reverse rotation of the driving motor, driven by the transmission unit, the two locking arms can just perform the approaching or separating actions, thus well meeting the driving requirements for the clamping or disengaging actions of the two locking arms.

[0037] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] Embodiment 1

[0039] This embodiment relates to a door auxiliary lock, which can improve the problem of abnormal noise generated by the shaking of the door relative to the door frame; an exemplary structure thereof is as shown in Figure 1 、 Figure 2 and Figure 3 shown.

[0040] Generally speaking, the door auxiliary lock includes a locking member and a locking cooperation member 4. One of the locking member and the locking cooperation member 4 is arranged on the door, and the other is arranged on the door frame corresponding to the door. Among them, the locking member includes a base 1 for fixing the locking member, two locking arms 2 oppositely arranged on the base 1, and a driving mechanism 3; the locking cooperation member 4 includes a connecting seat 40 for fixing the locking cooperation member 4, and a locking column 41 arranged on the connecting seat 40. The locking column 41 can extend between the two locking arms 2 as the door is closed, and the driving mechanism 3 can drive the two locking arms 2 to approach or separate to clamp or release the locking column 41.

[0041] It should be noted that based on the above overall design concept, the technical solution of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above-mentioned door can be a rear door or a door on the side of the vehicle; when the locking member is arranged on the door, the locking cooperation member 4 can be arranged on the door frame; when the locking cooperation member 4 is arranged on the door, the locking member can be arranged on the door frame. Taking the rear door as an example, the base 1 of the locking member can be fixed on the door frame, and the connecting seat 40 of the locking cooperation member 4 can be fixed on the rear door.

[0042] For the parts required for the implementation of the overall solution but not involved in the above overall setting, reference can be made to the mature setting means in the art, the actual situation during implementation, etc. for reasonable and flexible design. The following specific implementation solutions of this embodiment are only one of the relatively better solutions among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various specific forms of combinations and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.

[0043] Specifically, as shown in Figure 3As shown in the figure, the base 1 of this embodiment includes a connecting chassis 10, and two brackets respectively arranged at the top and bottom of the connecting chassis 10; two locking arms 2 are respectively slidably arranged on the two brackets, and the driving mechanism 3 drives the two locking arms 2 to move synchronously to complete the approaching or separating action. By relatively arranging two brackets on the base 1 and slidably arranging the two locking arms 2 on the two brackets respectively, through the driving of the driving mechanism 3, the approaching or separating movement action of the two locking arms 2 can be well realized.

[0044] Regarding the specific design form of the locking arm 2, of course, there are many different structural schemes to choose from. In this embodiment, the locking arm 2 includes an arm body 20, and a clamping portion 21 and a stud 22 respectively arranged at both ends of the arm body 20; elongated pin holes 100 are provided on both brackets, and the stud 22 is slidably arranged in the pin hole 100 on the corresponding bracket; two clamping portions 21 belonging to the two locking arms 2 are clamped and cooperated with the locking column 41.

[0045] Of course, there are many specific setting methods of the locking arm 2 on the base 1. In addition to the above-mentioned sliding setting form, it can also be connected in a hinged form; when adopting the hinged form, structures such as swing rods and connecting rods can be arranged between the driving mechanism 3 and the locking arm 2 to realize the reverse synchronous swing of the two locking arms 2, so as to realize the approaching or separating action of the two locking arms 2 to clamp or unlock the locking column 41. However, in this embodiment, the locking arm 2 is slidably arranged on the base 1, and the form of cooperation between the elongated pin hole 100 and the clamping portion 21 can well realize the small-distance sliding action of the locking arm 2 on the base 1; on the basis of such a setting, by arranging transmission structures such as lead screws and cams between the driving mechanism 3 and the locking arm 2, the reverse synchronous movement of the two locking arms 2 can be well realized.

[0046] Based on the above setting situation, the clamping surface of the arc-shaped clamping portion 21 facing the side of the locking column 41 is formed on the clamping portion 21 of this embodiment. When the two clamping portions 21 clamp the locking column 41, the clamping surface is in contact and cooperation with the column surface of the locking column 41. By arranging an arc-shaped clamping surface on the clamping portion 21 of the locking arm 2, the clamping contact area between the clamping portion 21 and the locking column 41 can be increased, thereby improving the clamping force between the two, and making the locking connection between the locking member and the locking cooperation member 4 more stable and reliable.

[0047] Furthermore, a locking column thread 410 can also be arranged on the column surface of the locking column 41, and a clamping thread 210 is correspondingly arranged on the clamping surface; when the two clamping portions 21 clamp the locking column 41, the locking column thread 410 and the clamping thread 210 are meshed and connected. By arranging a threaded meshing connection structure between the locking column 41 and the clamping surface, the connection strength between the clamping portion 21 and the locking column 41 can be further improved to enhance the locking reliability between the locking cooperation member 4 and the locking member.

[0048] Regarding the setting of the driving mechanism 3, of course, there are also various different structural schemes to choose from. In this embodiment, the driving mechanism 3 includes a driving motor 30 and a transmission unit disposed between the driving motor 30 and the two locking arms 2; in different rotation directions, the driving motor 30 drives the transmission unit to drive the two locking arms 2 to complete the approaching or separating actions. The driving mechanism 3 adopts an electric drive form, which has the characteristics of being easy to control and having flexible response; through the forward rotation and reverse rotation of the driving motor 30, driven by the transmission unit, the two locking arms 2 can just achieve the approaching or separating actions, thus well meeting the driving requirements for the clamping or disengaging actions of the two locking arms 2.

[0049] Specifically, the transmission unit of this embodiment includes a screw rod 31 connected to the power output shaft of the driving motor 30, and threaded holes 200 with opposite helix directions are respectively formed on the two locking arms 2; the screw rod 31 is simultaneously screwed into the two threaded holes 200. The transmission unit adopts a lead screw drive form, which has the advantages of good transmission stability and large transmission force; by respectively arranging threaded holes 200 with opposite helix directions on the two locking arms 2 and matching with the threads on the screw rod 31, when the driving motor 30 drives the screw rod 31 to rotate, it can well drive the two locking arms 2 to slide synchronously in opposite directions on the base 1 to achieve the approaching or separating actions, and then clamp or disengage the locking column 41.

[0050] When adopting the lead screw drive form of the above-mentioned screw rod 31, preferably, the screw rod 31 is arranged perpendicular to the locking column 41, and the axis of the screw rod 31 and the axis of the locking column 41 intersect. The axes of the screw rod 31 and the locking column 41 adopt a perpendicular intersection arrangement form, which is convenient to respectively arrange the clamping parts 21 of the two locking arms 2 at the opposite positions on both sides of the locking column 41, so that the clamping force of the clamping parts 21 on the locking column 41 is more balanced. Based on the above setting, the two brackets are respectively arranged at the top and bottom of the connecting chassis 10 of the base 1, specifically including an upper bracket 11 and a lower bracket 12, wherein a motor mounting bracket 13 is integrally connected to the bottom of the lower bracket 12, the above-mentioned driving motor 30 is fixed on the motor mounting bracket 13, and the screw rod 31 is vertically arranged upward and connected to the output shaft of the driving motor 30. The threaded holes 200 on the locking arm 2 are arranged at the middle position of the arm body 20, and the screw rod 31 sequentially passes through the threaded holes 200 on the lower locking arm 2 and the threaded holes 200 on the upper locking arm 2. The two clamping parts 21 are respectively located directly above and directly below the locking column 41. When the driving motor 30 rotates forward, driven by the screw rod 31, the two clamping parts 21 approach each other to clamp the locking column 41; when the driving motor 30 rotates in reverse, also driven by the screw rod 31, the two clamping parts 21 move away from each other to disengage the locking column 41.

[0051] In summary, for the door auxiliary lock of this embodiment, by providing two split lock arms 2 on the locking member, driven by the driving mechanism 3, the two lock arms 2 can approach or separate to perform a clamping action, so as to clamp and lock the lock post 41 on the locking and mating member 4 extending between the two lock arms 2, enabling flexible locking and detachment between the locking member and the locking and mating member 4; the locking member and the locking and mating member 4 are respectively arranged on the vehicle door and the door frame, thus providing a flexibly detachable and lockable connection point between the vehicle door and the door frame, which helps to improve the problem of abnormal noise caused by the vehicle door shaking relative to the door frame.

[0052] Embodiment 2

[0053] This embodiment relates to a vehicle, the rear of which is provided with a side-opening rear door, and a door auxiliary lock provided in Embodiment 1 is arranged between the rear door and the door frame; an exemplary structure of the rear door of this embodiment is as Figure 4 shown.

[0054] By arranging the above-mentioned door auxiliary lock between the rear door and its door frame, it has the technical advantages of the above-mentioned door auxiliary lock. Moreover, when the rear door is closed, the door auxiliary lock is in a locked state, adding a fixed connection point between the rear door and the door frame. Even when the rear door is affected by the gravity of the spare tire 51 mounted on the back, the shaking of the rear door during vehicle bumping will be greatly reduced, thus improving the problem of easy abnormal noise between the side-opening rear door and the door frame.

[0055] Regarding the specific installation position of the door auxiliary lock on the rear door, it can of course be set flexibly. Preferably, the door auxiliary lock is arranged at the top corner position on the side where the door lock of the rear door is located; specifically, as Figure 4 shown, when the door lock of the rear door is arranged on the left side of the door body 50, the door auxiliary lock is arranged at the upper left corner position of the door body 50.

[0056] For the case where there are two hinges on one side of the rear door and one door lock on the other side, when the door is closed, a situation as Figure 4The three-point fixed connection form of two hinge connection positions 52 and one door lock connection position 53 shown in the figure. The negative focus of the spare tire 51 mounted on the back is located on the outer side of the middle part of the back door. Since there is no connection and fixing point at the top of the back door, the top of the back door on the door lock side is more likely to repeatedly turn outwards and recover during vehicle bumping, resulting in rattling noises caused by shaking at this position. Based on the above situation, the door auxiliary lock is set at the top corner position on the side where the door lock of the back door is located. Setting the door auxiliary lock at the position where the connection tightness needs to be strengthened most can better improve the problem of rattling noises easily generated between the back door and the door frame. Moreover, the door auxiliary lock of the present utility model can be well controlled to achieve the disengaged and locked states to meet the requirements of opening and closing control of the door. During specific installation and layout, the locking and mating part 4 can be fixedly installed on the back door, the locking part is arranged inside the sheet metal of the door frame, and an avoidance hole is arranged on the sheet metal surface. When the back door is closed, the lock post 41 can be inserted between the two clamping parts 21 of the locking part through the avoidance hole. Such a setting can keep the outer surfaces of the door and the door frame clean, and the installation and assembly operation is simple and feasible.

[0057] By adding a door auxiliary lock with an adaptive stroke at the weak stiffness position of the back door, when the vehicle is in bumpy and harsh road conditions, the door auxiliary lock can be used to increase the connection and fixing points between the back door and the door frame to achieve auxiliary locking, so as to better fix the back door and the door frame together as a whole, and improve the problems of deformation of the door frame and rattling noises of the back door.

[0058] The above is only the preferred embodiment of the present utility model. The detailed explanation of the configuration situation, the examples of specific structural settings, or the description of the assembly and connection methods, etc., are all for the need of full disclosure so that those skilled in the art can better implement the present utility model, rather than to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
