However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0029] Combination Figures 1 to 3 As shown, according to a specific embodiment of the utility model, a locking device for fixing and locking a vehicle door is provided.

[0030] Specifically, the locking device includes a positioning assembly 10, a connecting assembly 20 and a damping assembly 30, at least part of the positioning assembly 10 is used to connect to the vehicle frame, and another part of the positioning assembly 10 is used to connect to the vehicle door to be fixed; the connecting assembly 20 is connected to at least part of the positioning assembly 10; the connecting assembly 20 is connected to at least part of the positioning assembly 10 through the damping assembly 30, and the damping assembly 30 limits the vehicle door to be fixed to limit the angle between the vehicle door to be fixed and the vehicle frame.

[0031] In this embodiment, the locking device includes a positioning assembly 10, a connecting assembly 20 and a damping assembly 30. At least part of the positioning assembly 10 is used to connect with the vehicle frame, and the other part of the positioning assembly 10 is used to connect with the vehicle door to be fixed. The connecting assembly 20 is connected to at least part of the positioning assembly 10. The connecting assembly 20 is connected to at least part of the positioning assembly 10 through the damping assembly 30. The damping assembly 30 limits the vehicle door to be fixed to limit the angle between the vehicle door to be fixed and the vehicle frame. The vehicle door to be fixed is connected to the vehicle frame through the positioning assembly 10 and the connecting assembly 20, and the angle between the vehicle door to be fixed and the vehicle frame is limited through the damping assembly 30. The fixing is firm, the locking device is simple to operate, and can be used repeatedly, which solves the problem of unreliable fixing strength, inconvenient operation, and high cost caused by wire bundling in the prior art.

[0032] Furthermore, the connecting assembly 20 includes a connecting rod 21, and the connecting rod 21 includes a first component segment 211 and a second component segment 212; the first end of the first component segment 211 is connected to a part of the positioning assembly 10 through the damping assembly 30; the second component segment 212 is connected to the second end of the first component segment 211; wherein the first component segment 211 and the second component segment 212 are arranged at an angle.

[0033] In this embodiment, the end of the second component segment 212 away from the first component segment 211 is preferably configured as a structure with a deformable and adjustable bending angle, so that in actual applications, by fine-tuning the bending angle of the end of the second component segment 212 away from the first component segment 211, part of the positioning assembly 10 can be better connected to the vehicle body, thereby avoiding dimensional deviation that makes the tooling unusable.

[0034] Furthermore, the angle between the first segment 211 and the second segment 212 is set in a range of 25° to 35°. This arrangement allows the second segment 212 to better cooperate with the positioning assembly 10 to limit the opening and closing angle of the vehicle body and the door when in use, and can also reduce the adverse torsional force caused to the whole when the second segment 212 is connected to the damping assembly 30.

[0035] Furthermore, the damping assembly 30 includes an elastic member 31 , a first end of the elastic member 31 is connected to a portion of the positioning assembly 10 , and a second end of the elastic member 31 is connected to a first end of the first assembly segment 211 .

[0036] In this embodiment, the elastic force of the elastic member 31 cooperates with the positioning assembly 10 to achieve a tight connection between the vehicle door and the vehicle body, thereby ensuring the opening and closing angle of the vehicle door and the vehicle body.

[0037] Furthermore, the positioning assembly 10 includes a flange 11 and a buckle 12. The flange 11 is connected to the first end of the elastic member 31, and the flange 11 is used to connect to the vehicle frame. The buckle 12 is connected to the second end of the first component segment 211, and the buckle 12 is used to connect to the door to be fixed. The flange 11, the buckle 12, the connecting rod 21 and the elastic member 31 can better cooperate to achieve the fixing of the opening and closing angle of the limiting vehicle body and the door.

[0038] In this embodiment, the flange 11 is fixed to the embedded end face of the lock hole of the vehicle door frame with screws, and the connecting component 20 is fixed to the lock hole of the vehicle door by the front end buckle 12. When the connecting component 20 rotates around the elastic member 31, the elastic force of the elastic member 31 quickly pulls the connecting component 20 back to the original position, thereby playing a role in fixing and limiting the door. Compared with the prior art method of fixing the door by bundling with wire harnesses, the fixing strength and accuracy are enhanced, the labor intensity and fixing consumables are reduced, and it is more reliable and practical.

[0039] Combination Figure 1 and Figure 3 As shown, in one embodiment of the present application, the ends of the flange 11 and the buckle 12 are both curved, so that the connection between the flange 11 and the vehicle frame, and the connection between the buckle 12 and the door to be fixed are not easy to slip, thereby achieving a better fixing effect.

[0040] Furthermore, the elastic member 31 is a spring, the flange 11 is connected to a first end of the spring, and the buckle 12 is connected to a second end of the spring through the first group segment 211 .

[0041] In the above embodiment, this arrangement is to simultaneously satisfy the connection between the flange 11 and the vehicle frame, and the connection between the buckle 12 and the door to be fixed, and to limit the opening and closing angle of the vehicle body and the door through the cooperation of the spring, thereby improving the practicality of the locking device.

[0042] Furthermore, the hardness of the elastic member 31 is HRC40-55. This is to ensure that the elastic member 31 limits the position of the door to be fixed, strengthen the hardness of the elastic member 31, limit the angle between the door to be fixed and the vehicle frame, and prevent the existing door bundling and locking method from having unreliable resistance to tank liquid impact strength, and the risk of deformation or collision with equipment caused by the circulating impact of tank liquid after entering the tank.

[0043] In one embodiment of the present application, the hardness of the elastic member 31 is HRC45-50. Such a configuration can ensure the reliability of the elastic member 31 in limiting the position of the door to be fixed, so as to limit the angle between the door to be fixed and the vehicle frame.

[0044] Furthermore, projecting along the axial direction of the elastic member 31, the straight line where the first end of the elastic member 31 is located is the first straight line, the straight line where the second end of the elastic member 31 is located is the second straight line, and the angle formed by the first straight line and the second straight line is 115° to 125°.

[0045] Combination Figure 1 As shown, in this embodiment, the straight line where the first end of the elastic member 31 is located is the first straight line, the straight line where the second end of the elastic member 31 is located is the second straight line, and the angle formed by the first straight line and the second straight line is 120°.

[0046] Furthermore, the positioning assembly 10, the connecting assembly 20 and the damping assembly 30 are an integrally formed structure, which facilitates the processing and production of the locking device.

[0047] In one embodiment of the present application, the flange 11, the buckle 12, the connecting rod 21 and the first and second segments 211 and 212 of the elastic member 31 are formed by bending a steel bar, the buckle 12 and the connecting rod 21 are fixedly connected by welding, and the flange 11 and the elastic member 31 are fixedly connected by welding. Since the steel bar itself has toughness, the elastic force of the elastic member 31 and the toughness of the steel bar itself can better fasten the door and the body, thereby effectively ensuring the opening and closing angle of the door and the body.

[0048] Specifically, when the locking device is used, the flange 11 and the buckle 12 are positioned and connected to the vehicle body and the door respectively, the elastic member 31 and the connecting rod 21 generate elastic force and elastic force transmission, and a limit is formed by the flange 11 and the buckle 12 to promote force balance and tightening, thereby realizing the control of the opening angle of the door and the vehicle body.

[0049] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0050] 1. The door to be fixed is connected to the vehicle frame by the positioning assembly 10 and the connecting assembly 20, and the angle between the door to be fixed and the vehicle frame is limited by the damping assembly 30, so that the door is fixed firmly, which solves the problem of unreliable fixing strength caused by wire bundling in the prior art.

[0051] 2. The locking device is easy to operate, which solves the problem of difficult operation, complicated operation, and low efficiency of the door bundling and fixing method in the prior art, thereby improving work efficiency.

[0052] 3. The locking device can be used repeatedly, but the metal wire used for bundling is wasted a lot. After being cut once, it cannot be recycled, resulting in a large waste of consumables and high costs.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present utility model.

[0055] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
