Description

Technical Field

[0001] The present application relates to the field of vehicle engineering technology, and in particular to a control box for a vehicle. Background Art

[0002] In L4 level unmanned port operation vehicles, controllers, power supplies and other electronic devices are indispensable and are generally placed in the control box, while some controllers themselves are not waterproof. The existing L4 level unmanned port control box for vehicles can generally only prevent water from entering the control box in the case of water spraying and splashing.

[0003] In extreme rainstorms at the port, water will accumulate in low-lying areas of the site. During the operation of the operating vehicle, there is a risk of water immersion at the bottom of the control box. At this time, the control box cannot meet the waterproof conditions and the controller has a high risk of water immersion.

[0004] In the existing technical solutions, most control boxes use ordinary rotating shaft hinges to open and close their doors, which results in uneven compression of the sealing strip during closing of the control box. The compression of the sealing strip on the side away from the hinge is smaller, and the clamping force is insufficient, resulting in leakage when immersed in water. If the overall compression of the sealing strip is increased, the compression on the side close to the hinge will be too large, making it difficult to close the control box body, and even causing deformation of the door panel on the side close to the hinge, affecting use.

DETAILED DESCRIPTION

[0026] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0028] At present, under extreme rainstorm weather at the port, water will accumulate in low-lying areas within the site. During the driving of the operating vehicle, there will be a risk of water immersion at the bottom of the control box. The existing control box cannot meet the waterproof conditions and the controller has a high risk of water immersion.

[0029] The inventors of the present application have discovered through research that, in the existing technical solutions, most control boxes use an ordinary rotating shaft hinge to open and close their doors, which results in uneven compression of the sealing strip during closing of the control box. The compression of the sealing strip on the side away from the hinge is smaller, and insufficient clamping force can easily lead to leakage when immersed in water. If the overall compression of the sealing strip is increased, the compression of the sealing strip on the side close to the hinge will be too large, making it difficult to close the control box body, and even causing deformation of the door panel on the side close to the hinge, affecting use.

[0030] In order to solve the problems in the prior art, the present application provides a control box for a vehicle, which is described in detail below in conjunction with the accompanying drawings.

[0031] Figure 1 A schematic diagram of the structure of a control box for a vehicle provided in an embodiment of the present application when the cover is closed; Figure 2 for Figure 1 A partial enlarged view of the middle A area; Figure 3 A schematic diagram of the structure of a control box for a vehicle provided in an embodiment of the present application when the cover is opened; Figure 4 for Figure 3 A partial enlarged view of the middle B area; Figure 5 It is a schematic diagram of the matching structure of the adapter and the slide slot in a movable state; Figure 6 It is a schematic diagram of the matching structure of the adapter and the slide groove in a closed state; Figure 7 for Figure 6 A partial enlarged view of the middle C area.

[0032] See also Figures 1 to 6The embodiment of the present application provides a control box for a vehicle, including a box body, a connecting assembly and an elastic sealing member. The box body includes a box body 1 and a cover body 2. The box body 1 includes a side wall and a storage space formed by the side wall. One side of the box body 1 is provided with an opening connected to the storage space, and the cover body 2 is opened and closed at the opening; the cover body 2 is rotatably connected to the side wall through a connecting assembly, and the connecting assembly includes a first connecting member 4 and a second connecting member 5 that are rotatably connected to each other. One of the first connecting member 4 and the second connecting member 5 is arranged on the cover body 2, and the other is arranged on the side wall near the opening position. One of the first connecting member 4 and the second connecting member 5 is provided with a slide groove 401, and the other is slidably connected to the slide groove 401. When the cover body 2 covers the opening, In the state, the sliding direction of the first connecting member 4 relative to the second connecting member 5 is parallel to the direction of the opening; the elastic sealing member is installed on at least one of the box body 1 and the cover body 2, and when the cover body 2 covers the opening and one of the first connecting member 4 and the second connecting member 5 that is slidingly connected to the slide groove 401 is located in the extreme position state away from the box body 1, there is a gap between the cover body 2 and the elastic sealing member; wherein, the box body has a closed state and a movable state, in the closed state, the cover body 2 is tightly pressed against the opening position of the box body through the elastic sealing member; in the movable state, the cover body 2 can move relative to the box body 1 through the second connecting member 5 and the first connecting member 4.

[0033] The process of adjusting the box body from a movable state to a closed state is as follows: rotate the cover body 2 so that the cover body 2 covers the opening position. In this state, there is a gap between the cover body 2 and the elastic seal, or the cover body 2 is in contact with the elastic seal but the compression of the elastic seal is relatively small; apply a locking force in a direction parallel to the opening to make the cover body 2 and the box body 1 move toward each other. In this process, the first connecting member 4 and the second connecting member 5 slide through the slide groove 401, and the compression of the elastic seal gradually increases. When the locking force reaches the set value, the box body is in a closed state. It should be noted that the locking force can be applied to the box body 1 and the cover body 2 by an external device, or by a device installed on the box body.

[0034] It can be seen that in the process of applying the locking force, the cover body 2 will translate along the direction of the opening, toward the direction close to the box body 1, so that the compression amount of the elastic seal at each position is more balanced, which can achieve higher waterproof performance, and can avoid the problem of excessive compression of the sealing strip 14 near the hinge in the existing solution, making it difficult to close the cover body 2, and can avoid deformation of the box door caused by excessive compression of the elastic seal on one side; on the one hand, the elastic seal plays a waterproof role; on the other hand, it can ensure that when the cover body 2 is closed at the opening position, there will be no hard collision between the cover body 2 and the box body 1.

[0035] In some embodiments, the control box for a vehicle also includes a locking mechanism, including a first structural member and a second structural member that can be locked, one of the first structural member and the second structural member is installed on the box body 1, and the other is installed on the cover body 2. In a closed state, the first structural member and the second structural member are locked and connected to provide a locking force that tightly presses the cover body 2 against the box body 1, and the direction of the locking force is parallel to the direction of the opening.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the locking mechanism can select multiple adjustable pull-tab locks 6, and the multiple adjustable pull-tab locks 6 are arranged at the side wall position of the opening periphery, so that the box body can be adjusted to a closed state more conveniently. Specifically, the first structural member is the lock body 601 of the adjustable pull-tab lock 6, and the second structural member is the lock tongue 602 of the adjustable pull-tab lock 6. The lock body 601 of the adjustable pull-tab lock 6 is welded to the side wall at the corresponding position, and the lock tongue 602 of the adjustable pull-tab lock 6 is locked to the corresponding position of the cover body 2 by screws. When the cover body 2 is closed at the opening position, the lock tongue 602 can be pulled toward the box body 1 by adjusting the handle of the lock body 601 and the hook of the lock body 601, and the lock body 601 is in a locked state, so that the box body can be adjusted to a closed state. Since the adjustable pull-tab lock 6 can be directly purchased on the market and is a relatively conventional component in this field, its specific working principle will not be described in detail.

[0037] In other embodiments, the locking mechanism may use multiple locking screws, a through hole for the threaded section of the locking screw to pass through is provided in the cover body 2, and a threaded hole corresponding to the through hole is provided in the box body 1. When the cover body 2 is closed at the opening position, the threaded section of the locking screw is passed through the through hole and then locked to the threaded hole, so that the cover body 2 can be locked to the box body 1. In this embodiment, the first structural member is the locking screw, and the second structural member is the threaded hole provided in the box body 1. It should be noted that the locking screw should be arranged on the periphery of the elastic sealing member, and the threaded hole should be set as a blind hole to prevent rainwater from entering the box body through the through hole or the threaded hole.

[0038] like Figure 3 As shown, in some embodiments, the box body 1 is formed as a whole by sheet metal welding, square steel pipes 12 are welded at the corners inside the box body 1, and ribs 11 are welded between adjacent square steel pipes 12 to improve the strength of the box body 1.

[0039] In some embodiments, the bottom of the box body 1 is formed by sheet metal bending. If welding is required, full welding and sealing are used to prevent water from seeping into the interior of the box body 1 through the weld.

[0040] like Figure 1 and Figure 2As shown, in some embodiments, adapter brackets 3 are welded on both sides of the top of the box body 1. The adapter brackets 3 are provided to facilitate installation of the box body 1 to the corresponding vehicle.

[0041] like Figure 3 As shown, in some embodiments, some side walls are provided with reserved holes 13 for introducing components such as wiring harnesses, water pipes, and air conditioners. The reserved holes 13 are located at positions of the corresponding side walls away from the ground of the box body 1, thereby reducing the risk of water on the ground splashing into the reserved holes 13.

[0042] like Figure 4 As shown, in some embodiments, the first connecting member 4 is fixed to the box body 1, the slide groove 401 is set on the first connecting member 4, and the second connecting member 5 includes a first bracket 501 fixed to the cover body 2 and an adapter 502 installed on the first bracket 501, the adapter 502 extends out of the first bracket 501 and is slidably connected in the slide groove 401, the adapter 502 can rotate in the slide groove 401, the adapter 502 cooperates with the slide groove 401, so that the cover body 2 can rotate and slide relative to the box body 1, and the structure is relatively simple.

[0043] like Figure 4 As shown, in some embodiments, the adapter 502 is a columnar structure, and the adapter 502 is rotatably connected to the first bracket 501. The adapter 502 can rotate relative to the first bracket 501 and the slide groove 401, which can reduce the friction resistance when the cover body 2 rotates relative to the box body 1 to a certain extent, and has a labor-saving effect when the staff rotates the cover body 2.

[0044] like Figure 3 As shown, in some embodiments, the cover body 2 is fixedly connected to a second bracket 8, and a third bracket 10 is fixedly connected to the side wall near the opening position. When the cover body 2 is in an open state, a support rod is arranged between the second bracket 8 and the third bracket 10, so that the cover body 2 can be kept in an open state, which is convenient for the staff to inspect and repair the electronic components in the box body 1. In this embodiment, the support rod is a pneumatic support rod 9, which can support the cover body 2 during the process of opening the cover body 2 to prevent the cover body 2 from closing automatically.

[0045] like Figure 4 As shown, in some embodiments, the end of the adapter 502 extending out of the first bracket 501 and the end of the adapter 502 extending out of the slide groove 401 are both provided with an annular groove, and the annular groove is clamped with a retaining spring 503. The retaining spring 503 is used for limiting, which can prevent the adapter 502 from accidentally detaching from the first connecting member 4 and the first bracket 501 along its own axial direction, and at the same time prevent the adapter 502 from moving along its own axial direction, which can improve the connection stability between the cover body 2 and the box body 1.

[0046] like Figure 3As shown, in some embodiments, along the first direction, the inner sides of at least two first connectors 4 abut against the corresponding first brackets 501 or the inner sides of at least two first brackets 501 abut against the corresponding first connector 4, and the first direction is parallel to the rotation axis of the first connector 4 relative to the second connector 5, which can prevent the cover body 2 from sliding relative to the box body along the first direction, thereby further improving the stability of the overall structure of the control box for the vehicle.

[0047] In some embodiments, along the second direction, the difference between the height of the slide groove 401 and the height of the adapter 502 located in the slide groove 401 is between 0.2 mm and 0.4 mm. The second direction is also perpendicular to the rotation axis of the first connecting member 4 relative to the second connecting member 5 and the direction of the opening, ensuring that the adapter 502 can slide smoothly inside the slide groove 401, but will not produce abnormal noise due to looseness.

[0048] Figure 7 for Figure 6 A partial enlarged view of the middle C area.

[0049] like Figure 7 As shown, in some embodiments, the box body 1 is provided with a water diversion groove 15 on the outer periphery of the opening, and the water diversion groove 15 faces away from the opening. When it rains outside and the cover body 2 is closed, rainwater dripping onto the vicinity of the cover body 2 and the box body 1 and part of the rainwater on the top of the box body 1 will slide into the water diversion groove 15 and be diverted to the ground through the water diversion groove 15, thereby reducing the risk of rainwater seeping into the box.

[0050] like Figure 7 As shown, in some embodiments, the elastic sealing member includes a sealing strip 14, and the sealing strip 14 is installed on the first groove wall 16 of the water diversion groove 15. Specifically, in this embodiment, the sealing strip 14 is installed on the first groove wall 16 by snapping. In other embodiments, the sealing strip 14 can also be bonded to the first groove wall 16. In a closed state, the first groove wall 16 is the groove wall of the water diversion groove 15 close to the cover body 2. In a closed state, after the sealing strip 14 is compressed by force, the sealing strip 14 located at the outer edge of the first groove wall 16 will bulge in the direction close to the water diversion groove 15, so it is easier to drain rainwater dripping to this position into the water diversion groove 15.

[0051] In some embodiments, the sealing strip 14 is a single-bubble hollow sealing strip, which has a larger compression capacity and is softer than a solid sealing strip.

[0052] like Figure 3 As shown, in some embodiments, the cover body 2 is a plate-like structure, and a plurality of reinforcing rib profiles 7 are installed on one side of the cover body 2. In a closed state, the reinforcing rib profiles 7 are all located in the opening, which can improve the structural strength of the door and inhibit deformation of the cover body 2.

[0053] In some embodiments, a plurality of studs are convexly welded on one side of the cover body 2 where the reinforcing rib profile 7 is installed. The studs are threadedly connected with nuts, and the reinforcing rib profile 7 is pressed to the cover body 2 through the nuts. Compared with directly welding the reinforcing rib profile 7 to the cover body 2, welding the studs can reduce the welding area and prevent the weld from affecting the appearance of the cover body 2. The reinforcing rib profile 7 can be removed at any time, so that the reinforcing rib profile 7 can be reused.

[0054] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
