Description

Technical Field

[0001] The utility model relates to the technical field of automobile doors, in particular to a door auxiliary locking structure. In addition, the utility model also relates to a vehicle. Background Art

[0002] For the convenience of personnel entering and exiting or taking and placing works, doors are generally provided on the side of a vehicle, and a rear door that opens laterally and has a spare tire hanging on it 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 it 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 (the 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 a common 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 common mechanical lock is fixed and cannot adaptively adjust the opening or locking state according to the door state. Summary of the Utility Model

[0005] In view of this, the utility model aims to propose a door auxiliary locking structure to improve the problem of abnormal noise caused by the shaking of the door 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 locking structure includes a locking member provided on the door frame and a locking cooperation member provided on the door corresponding to the locking member;

[0008] The locking member includes a base fixed on the door frame, two locking tongues hinged on the base relatively, and a driving mechanism; the locking and cooperating member includes a connecting seat fixed on the vehicle door and a locking post arranged on the connecting seat;

[0009] As the vehicle door closes, the locking post can extend between the two locking tongues, and the driving mechanism can drive the two locking tongues to swing synchronously and reversely to clamp or release the locking post.

[0010] Furthermore, the base includes a connecting chassis and a connecting sleeve arranged on the connecting chassis. The locking post can extend into the inner cavity of the connecting sleeve. Two locking windows are oppositely opened on the side wall of the connecting sleeve, and the two locking tongues are respectively arranged in the two locking windows. Driven by the driving mechanism, the two locking tongues can partially enter the inner cavity to clamp the locking post.

[0011] Furthermore, hinge pins are arranged on both sides of the middle part of the locking tongue, and the locking tongue is hinged on the connecting sleeve through the hinge pins. The two ends of the locking tongue are respectively configured as a release end and a locking end, and a convex clamping platform is formed on the side of the locking end facing the inner cavity. Driven by the driving mechanism, the two clamping platforms belonging to the two locking tongues enter the inner cavity to clamp the locking post.

[0012] Furthermore, the surface of the clamping platform for clamping the locking post is configured as an arc-shaped surface that can fit on the column surface of the locking post.

[0013] Furthermore, locking post threads are arranged on the column surface of the locking post, and clamping threads are arranged on the clamping platform. When the two clamping platforms clamp the locking post, the locking post threads and the clamping threads are meshed and connected.

[0014] Furthermore, the driving mechanism includes a driving motor, a screw rod connected to the power output shaft of the driving motor, and a moving member slidably arranged on the connecting sleeve. The moving member can move axially on the connecting sleeve driven by the screw rod. The moving member moving to the locking end position can push the clamping platform into the inner cavity, and the moving member moving to the release end position can drive the clamping platform out of the inner cavity.

[0015] Furthermore, the moving member includes a gear ring sleeved outside the connecting sleeve. The gear ring is meshed and connected with the screw rod, and the inner wall of the gear ring is in abutting cooperation with the locking tongue.

[0016] Furthermore, a spiral-shaped slideway is opened on the outer wall of the connecting sleeve, and a guiding post is arranged on the gear ring. The guiding post is slidably arranged in the slideway.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] For the door auxiliary locking structure of the utility model, by arranging two split lock tongues on the locking member, driven by the driving mechanism, the two lock tongues can swing synchronously to perform a clamping action, so as to clamp and lock the lock post on the locking cooperation member extending between the two lock tongues, realizing flexible locking and detachment between the locking member and the locking cooperation member; the locking member and the locking cooperation member are respectively arranged on the door and the door frame, thus setting a connection point that can be flexibly detached and locked between the door and the door frame, which helps to improve the problem of abnormal noise caused by the shaking of the door relative to the door frame.

[0019] In addition, a connecting sleeve is arranged on the base of the locking member, and a locking window is opened on the side wall of the connecting sleeve. The lock tongue is swingably arranged in the locking window, which can not only well clamp the lock post extending into the inner cavity, but also help to reduce the radial dimension of the whole base, thus reducing the occupation of the internal space of the door frame sheet metal by the locking member.

[0020] Another object of the utility model is to provide a vehicle, the rear of which is provided with a side-opening rear door, and a door auxiliary locking structure as described in the utility model is arranged between the rear door and the door frame.

[0021] Furthermore, the door auxiliary locking structure is arranged at the top position on the side where the door lock of the rear door is located.

[0022] The vehicle of the utility model has the technical advantages of the above-mentioned door auxiliary locking structure; moreover, when the rear door is closed, the door auxiliary locking structure is in a locked state, adding a fixed connection point between the rear door and the door frame. Even if the rear door is affected by the gravity of the rear-mounted spare tire, when the vehicle bumps, the shaking of the rear door will be greatly reduced, thus improving the problem of easy abnormal noise between the side-opening rear door and the door frame.

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

[0039] Embodiment 1

[0040] This embodiment relates to a door auxiliary locking structure, 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 Figure 1 , Figure 2 , Figure 3 and Figure 4 shown.

[0041] Generally speaking, the door auxiliary locking structure includes a locking member provided on the door frame, and a locking cooperation member 4 correspondingly provided on the door. Among them, the locking member includes a base 1 fixed on the door frame, two locking tongues 2 relatively arranged and hinged on the base 1, and a driving mechanism 3. The locking cooperation member 4 includes a connecting seat 40 fixed on the door, and a locking column 41 provided on the connecting seat 40. As the door closes, the locking column 41 can extend between the two locking tongues 2, and the driving mechanism 3 can drive the two locking tongues 2 to swing synchronously and reversely to clamp or release the locking column 41.

[0042] 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 provided on the door, the locking cooperation member 4 can be provided on the door frame; when the locking cooperation member 4 is provided on the door, the locking member can be provided 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.

[0043] 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 optimal 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.

[0044] Specifically, in this embodiment, as Figure 4As shown, the base 1 includes a connecting chassis 10 and a connecting sleeve 11 disposed on the connecting chassis 10, and the lock column 41 can extend into the inner cavity 110 of the connecting sleeve 11. In addition, two locking windows 111 are relatively opened on the side wall of the connecting sleeve 11, and two locking tongues 2 are respectively arranged in the two locking windows 111; under the driving of the driving mechanism 3, the two locking tongues 2 can partially enter the inner cavity 110 to clamp the lock column 41. The connecting sleeve 11 is arranged on the base 1 of the locking piece, and the locking window 111 is opened on the side wall of the connecting sleeve 11. The locking tongue 2 can be swingably arranged in the locking window 111, which can not only well clamp the lock column 41 extending into the inner cavity 110, but also help to reduce the radial size of the entire base 1, thereby reducing the occupation of the internal space of the door frame sheet metal by the locking piece.

[0045] There are of course many designs for the specific hinge position of the lock tongue 2 on the connecting sleeve 11. In this embodiment, hinge pins 22 are provided on both sides of the middle of the lock tongue 2, and the lock tongue 2 is hinged to the connecting sleeve 11 through the hinge pins 22; Figure 4 As shown, a hinge frame 113 is respectively provided on the connecting sleeve 11 on both sides of the locking window 111, and two hinge pins 22 located on both sides of the lock tongue 2 are respectively hinged on the two hinge frames 113, so that the lock tongue 2 can swing well in the locking window 111.

[0046] Based on the setting of the above-mentioned hinged position, the two ends of the lock tongue 2 of this embodiment are respectively constructed as a release end 20 and a locking end 21, and the side of the locking end 21 facing the inner cavity 110 is formed on a raised clamping platform 210; under the drive of the driving mechanism 3, the two clamping platforms 210 belonging to the two lock tongues 2 enter the inner cavity 110 to clamp the lock column 41.

[0047] By setting a hinge pin 22 in the middle of the lock tongue 2, the two ends of the lock tongue 2 are respectively constructed as a release end 20 and a locking end 21. When the clamping platform 210 of the locking end 21 swings into the inner cavity 110, it can abut against the lock column 41 to achieve a locked connection between the locking piece and the locking fitting 4. As the release end 20, it should of course be set to be thinner. When the driving mechanism 3 drives the lock tongue 2 to swing in the opposite direction, the release end 20 can be swung into the locking window 111, so that the locking end 21 swings outward to move the clamping platform 210 out of the inner cavity 110, to achieve the release of the lock column 41, and thus release the locked state. Such a design provides two suitable fulcrums, the release end 20 and the locking end 21, for the driving mechanism 3 to drive the lock tongue 2, so as to facilitate the driving mechanism 3 to drive the lock tongue 2 to swing in both positive and negative directions.

[0048] In addition, the clamping table 210 of this embodiment for clamping the surface of the locking post 41 is configured to be an arc-shaped surface that can fit on the column surface of the locking post 41. By setting the surface of the clamping table 210 for abutting against the locking post 41 as an arc-shaped clamping surface, the clamping contact area between the clamping table 210 and the locking post 41 can be increased, thereby improving the clamping force between the two, making the locking connection between the locking member and the locking fitting 4 more stable and reliable.

[0049] On the basis of the above settings, preferably, a locking post thread 410 is provided on the column surface of the locking post 41 of this embodiment, and a clamping thread 211 is provided on the clamping surface of the clamping table 210; when the two clamping tables 210 clamp the locking post 41, the locking post thread 410 and the clamping thread 211 are meshed and connected. By providing a threaded meshing connection structure between the locking post 41 and the clamping surface, the connection strength between the locking end 21 and the locking post 41 can be further improved, so as to enhance the locking reliability between the locking fitting 4 and the locking window 111.

[0050] For the setting of the driving mechanism 3, of course, there are various solutions. In this embodiment, the driving mechanism 3 includes a driving motor 30, a screw rod 31 connected to the power output shaft of the driving motor 30, and a moving member slidably disposed on the connecting sleeve 11. At the same time, the moving member can move axially on the connecting sleeve 11 driven by the screw rod 31. The moving member moving to the position of the locking end 21 can push the clamping table 210 into the inner cavity 110, and the moving member moving to the position of the releasing end 20 can drive the clamping table 210 out of the inner cavity 110.

[0051] The driving mechanism 3 adopts a form of motor drive, 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 screw rod 31, the moving member moves axially, and can respectively push the releasing end 20 and the locking end 21, so that the locking tongue 2 can just swing in two opposite directions, thus well meeting the driving needs of the clamping or disengaging actions of the two locking tongues 2.

[0052] Specifically, the moving member of this embodiment includes a gear ring 32 sleeved outside the connecting sleeve 11. The gear ring 32 is meshed and connected with the screw rod 31, and the inner wall of the gear ring 32 is in abutting fit with the locking tongue 2. The moving member adopts the structural form of the gear ring 32, and can achieve a screw drive form with the screw rod 31, converting the rotational motion around the axis into axial movement, having advantages such as good transmission stability and large transmission force; when the driving motor 30 drives the screw rod 31 to rotate, the gear ring 32 is also driven to rotate and axially slide on the connecting sleeve 11, and can well drive the two locking tongues 2 to perform swinging actions to clamp or disengage the locking post 41.

[0053] In addition, a spiral chute 112 is provided on the outer wall of the connecting sleeve 11 of this embodiment, and a guiding post 320 is provided on the gear ring 32. The guiding post 320 is slidably arranged in the chute 112. By providing the chute 112 on the connecting sleeve 11, even if there is a gap between the gear ring 32 and the connecting sleeve 11, smooth sliding of the gear ring 32 on the connecting sleeve 11 can be achieved; of course, the spiral distribution dimension parameters of the chute 112 should be set accordingly according to the meshing tooth transmission parameter situation between the screw 31 and the gear ring 32, so as to ensure that under the drive of the screw 31, the rotation angle and movement dimension of the gear ring 32 are adapted; it can be designed on the principle that the gear ring 32 can smoothly slide on the connecting sleeve 11 driven by the screw 31.

[0054] To sum up, for the door auxiliary locking structure of this embodiment, by providing two split lock tongues 2 on the locking member, driven by the driving mechanism 3, the two lock tongues 2 can swing synchronously to perform a clamping action, so that the lock post 41 on the locking and cooperating member 4 extending between the two lock tongues 2 can be clamped and locked, realizing flexible locking and detachment between the locking member and the locking and cooperating member 4; the locking member and the locking and cooperating member 4 are respectively arranged on the vehicle door and the door frame, thus setting 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.

[0055] Embodiment 2

[0056] This embodiment relates to a vehicle. A side-opening rear door is provided at the rear of the vehicle, and the door auxiliary locking structure provided in Embodiment 1 is provided between the rear door and the door frame; an exemplary structure of the rear door of this embodiment is as Figure 5 shown.

[0057] By providing the above-mentioned door auxiliary locking structure between the rear door and its door frame, it has the technical advantages of the above-mentioned door auxiliary locking structure. Moreover, when the rear door is closed, the door auxiliary locking structure is in a locked state, adding a fixed connection point between the rear door and the door frame. Even if the rear door is affected by the gravity of the spare tire 51 mounted on the back, when the vehicle jolts, the shaking of the rear door will be greatly reduced, thus improving the problem of abnormal noise easily generated between the side-opening rear door and the door frame.

[0058] Regarding the specific installation position of the door auxiliary locking structure on the rear door, preferably, it is installed at Figure 5 the upper left corner of the door body 50 as shown; that is, the door auxiliary locking structure is arranged at the top position on the side where the door lock of the rear door is located.

[0059] 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 shown in Figure 5The three-point fixed connection form of two hinge connection positions 52 and one door lock connection position 53 shown in the figure. The negative point of the spare tire 51 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 when the vehicle jolts, resulting in rattling noises caused by shaking at this position. Based on the above situation, the door auxiliary locking structure is set at the top position on the side where the door lock of the back door is located. By setting the door auxiliary locking structure at the position where the connection tightness needs to be strengthened the most, the problem of easy rattling between the back door and the door frame can be better improved. Moreover, the door auxiliary locking structure of the present utility model can be well controlled to achieve the disengaged and locked states to meet the opening and closing control requirements of the door. During specific installation and arrangement, the locking and mating part 4 can be fixedly installed on the back door, the locking part is set inside the sheet metal of the door frame, and an avoidance hole is provided on the sheet metal surface. When the back door is closed, the locking post 41 can be inserted between the two locking tongues 2 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.

[0060] By adding a door auxiliary locking structure with an adaptive stroke at the weak stiffness position of the back door, when the vehicle is in a bumpy and harsh road condition, the door auxiliary locking structure can be used to increase the connection and fixing points between the back door and the door frame to achieve auxiliary locking, thereby better fixing the back door and the door frame together as a whole, and improving the problems of deformation of the door frame and rattling noises caused by shaking of the back door.

[0061] The above is only the preferred embodiment of the present utility model. The detailed explanation of the configuration, 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 modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
