DETAILED DESCRIPTION

[0039] In the development process of a vehicle, it is necessary to test the performance of the vehicle based on a LabCar test system. A vehicle bench in the LabCar test system is used to fix a sample vehicle to be tested to complete the vehicle test. The vehicle bench is usually built by a vehicle body frame and a vehicle body panel, and the size, shape and component setting of the vehicle bench are determined based on the size, shape and component setting of the actual vehicle. Therefore, the vehicle body panel in the vehicle bench is determined based on the vehicle body panel of the actual vehicle. Further, when the vehicle bench is built by the vehicle body frame and the vehicle body panel, the vehicle body panel and the vehicle body frame are usually assembled by bolts. When the vehicle body panel and the vehicle body frame are assembled by bolts, the operation is slow, each bolt needs to be tightened, and the time required for tightening is long. When the vehicle body panel on the vehicle body frame is disassembled, each bolt needs to be unscrewed, so that the vehicle body panel cannot be quickly disassembled. Further, the vehicle body panel in the vehicle bench is determined based on the vehicle body panel of the actual vehicle, so that the vehicle body panel can only be used for the construction of the vehicle bench of the corresponding project, causing waste of cost.

[0040] For example, a vehicle bench built by aluminum alloy profiles is described. The vehicle body frame is an aluminum alloy frame, the vehicle body panel is an aluminum alloy panel, and the vehicle body panel is determined based on the size and shape of the actual vehicle corresponding to the project. When building the vehicle bench, the aluminum alloy frame and the aluminum alloy panel are assembled by bolts, so that the aluminum alloy panel on the aluminum alloy frame cannot be quickly disassembled, and when building different projects, since the aluminum alloy panel is determined based on the actual vehicle of the project, the aluminum alloy panel cannot be adapted to other projects, so that the aluminum alloy panel cannot be reused, and can only be used for the construction of the vehicle bench of the project.

[0042] The vehicle test bench provided by the utility model is detachably fixed on vehicle body frame based on self-locking mechanism.Further, in the self-locking mechanism, the first blocking portion is structure that is retracted in the extension by the first through hole in the case of being in retracted state, so that the extension can pass through the connecting hole, and is extended out of the extension by the first through hole in the case of being in unfolded state.Therefore, the first blocking portion in the self-locking mechanism is retracted under stress, so that the extension can pass through the connecting hole on the vehicle body panel and the vehicle body frame, and the first blocking portion is unfolded under no stress, so that the first blocking portion is extended out of the extension by the first through hole.Therefore, after the extension of the self-locking mechanism passes through the connecting hole on the vehicle body frame and the connecting hole on the vehicle body panel, the first blocking portion and the second blocking portion are respectively located at both sides of the overlapping area of the vehicle body frame and the vehicle body panel, to fix the vehicle body frame and the vehicle body panel.Therefore, when the vehicle body panel and the vehicle body frame are connected by the self-locking mechanism, the installation or dismounting of the vehicle body panel on the vehicle body frame can be completed by only applying stress on the first blocking portion or removing the applied stress, so that the vehicle body panel on the vehicle body frame can be quickly assembled or dismounted.Further, the building rate of the vehicle test bench can be improved, to improve the vehicle testing efficiency.

Therefore, the connection between the connecting piece 212 and the bracket 211 is based on the clamping of the first connecting part 2121 in the connecting groove 2111 of the bracket 211.

[0049] Further, the second connecting part 2122 can be set as a sheet structure or a plate structure, so as to tightly fit the second connecting part 2122 with the body panel 1, and then be clamped and fixed based on the self-locking mechanism 3, thereby making the connection between the body frame 2 and the body panel 1 more stable.

[0050] With reference to Figure 4 Further, a plurality of connecting grooves 2111 can be arranged in the bracket 211, so that the same bracket 211 can be connected with a plurality of connecting pieces 212 at the same time, thereby making the same body frame piece 21 be connected with a plurality of body panels 1 at the same time.

[0051] With reference to Figure 4 Further, adjacent body frame pieces 21 can be connected through a hinge 4 or a bolt structure.

[0052] Further, for the structure of the body frame 2, the above is only described based on the structure of the body frame 2 in one specific embodiment, but the specific structure of the body frame 2 is not limited, and can be determined based on specific requirements and scenes.

[0055] Reference Figure 5 , Figure 5 To Figure 1 Figure 6 shows a cross-sectional view of the vehicle bench in which the body frame, the body panel and the self-locking mechanism are in a connected state. The self-locking mechanism 3 includes a first blocking portion 31, an extension portion 32 and a second blocking portion 33, the first blocking portion 31 and the second blocking portion 33 are respectively arranged at both ends of the extension portion 32, and the first blocking portion 31 is arranged with a first through hole at one end of the extension portion 32, further, the extension portion 32 is in a hollow structure, so that the first blocking portion 31 can be retracted into the extension portion 32 under stress. Further, the weight of the vehicle bench can be reduced.

[0056] Further, when the first blocking portion 31 is in an expanded state, the size of the first blocking portion 31 is greater than the size of the connecting hole 22, so that the first blocking portion 31 can fix the body panel 1 and the body frame 2 between the second blocking portion 33 and the first blocking portion 31 when the first blocking portion 31 is in the expanded state, to fix the body panel 1 on the body frame 2.

[0057] Reference Figure 5 When the body frame 2 and the body panel 1 are connected based on the self-locking mechanism 3, the body panel 1 and the body frame 2 are attached, the first blocking portion 31 in the self-locking mechanism 3 is stressed and is in a retracted state, and the extension portion 32 sequentially penetrates the connecting holes 22 on the body panel 1 and the body frame 2, or the extension portion 32 sequentially penetrates the connecting holes 22 on the body frame 2 and the body panel 1. At this time, the second blocking portion 33 in the self-locking mechanism 3 cannot pass through the connecting holes 22 on the body frame 2 and the body panel 1, and the second blocking portion 33 is attached to the side of the body panel 1 or the body frame 2 away from the first blocking portion 31. After the extension portion 32 penetrates the body panel 1 and the body frame 2, the first through hole on the extension portion 32 is located on the side of the body frame 2 away from the body panel 1 or the side of the body panel 1 away from the body frame 2. At this time, the first blocking portion 31 is not stressed and is in an expanded state, and the first blocking portion 31 extends out of the extension portion 32 through the first through hole, so that the first blocking portion 31 is attached to the side of the body panel 1 or the body frame 2 away from the second blocking portion 33 outside the extension portion 32. Therefore, the body panel 1 and the body frame 2 are fixed between the second blocking portion 33 and the first blocking portion 31 to fix the body panel 1 on the body frame 2.

[0058] The vehicle bench provided by the utility model is characterized in that the vehicle body panel 1 is detachably fixed on the vehicle body frame 2 through the self-locking mechanism 3. The first blocking part 31 in the self-locking mechanism 3 is contracted under stress, so that the extension part 32 can pass through the connecting holes 22 on the vehicle body panel 1 and the vehicle body frame 2, and the first blocking part 31 is extended out of the extension part 32 through the first through hole under the condition that the first blocking part 31 is not stressed. Therefore, the first blocking part 31 and the second blocking part 33 are respectively located on the two sides of the overlapping area of the vehicle body frame 2 and the vehicle body panel 1 after the extension part 32 of the self-locking mechanism 3 passes through the connecting holes 22 on the vehicle body frame 2 and the connecting holes 22 on the vehicle body panel 1, so as to fix the vehicle body frame 2 and the vehicle body panel 1. Therefore, the installation or dismounting of the vehicle body panel 1 on the vehicle body frame 2 can be completed by only applying stress on the first blocking part 31 or removing the applied stress when the vehicle body panel 1 and the vehicle body frame 2 are connected through the self-locking mechanism 3, so that the quick assembly or dismounting of the vehicle body panel 1 on the vehicle body frame 2 is realized. Further, the building rate of the vehicle bench can be improved, so as to improve the vehicle testing efficiency.

[0059] Further, the second blocking part 33 in the self-locking mechanism 3 is used for preventing the self-locking mechanism 3 from completely passing through the vehicle body frame 2 and the vehicle body panel 1, so as to clamp the vehicle body panel 1 and the vehicle body frame 2 between the second blocking part 33 and the first blocking part 31. Therefore, the second blocking part 33 only needs to meet the condition that the second blocking part 33 cannot pass through the connecting holes 22 on the vehicle body panel 1 and the vehicle body frame 2 in a certain direction.

[0060] Further, the outer peripheral shape of the extension part 32 in the self-locking mechanism 3 is consistent with the shape of the connecting holes 22 on the vehicle body panel 1 and the vehicle body frame 2, so as to facilitate the extension part 32 to pass through the connecting holes 22 on the vehicle body panel 1 and the vehicle body frame 2. Further, the outer peripheral shape of the extension part 32 and the shape of the connecting holes 22 can be one of a circular shape, a rectangular shape and a triangular shape.

[0061] Further, at least two first through holes opposite in position are arranged on the extension part 32, and the number of the first through holes on the extension part 32 can be determined based on the structure of the first blocking part 31.

[0062] Reference Figure 6 and Figure 7 , Figure 6 is a structural schematic view of the self-locking mechanism, Figure 7 is Figure 6The diagram shows a top view of the self-locking mechanism. In a vehicle platform disclosed in this embodiment of the invention, the first blocking part 31 includes a telescopic member 311 and a fixing member 312. The telescopic member 311 includes a spring 3111 and a movable button 3112.

The movable end of the spring 3111 is fixedly connected to the movable button 3112, and the fixed end of the spring 3111 is fixedly connected to the fixing member 312. When the first blocking part 31 is in the retracted state, the movable button 3112 and the spring 3111 are retracted within the extension part 32. When the first blocking part 31 is in the extended state, the movable button 3112 extends out of the extension part 32 through a first through hole.

[0063] The vehicle platform provided by this utility model uses a telescopic component 311 and a fixing component 312 connected to form a first blocking part 31. The telescopic component 311 includes a spring 3111 and a movable button 3112. When the movable button 3112 is pressed, the spring 3111 contracts under force, allowing the movable button 3112 and the spring 3111 to retract into the extension part 32, so that the extension part 32 can pass through the connection hole 22 on the body panel 1 and the body frame 2. When the movable button 3112 is released, the spring 3111 is not under force, allowing the movable button 3112 to extend out of the extension part 32 through the first through hole, so as to fix the body panel 1 to the body frame 2. The operation is simple and saves time in assembling or removing the body panel 1 from the body frame 2.

[0064] Furthermore, in a possible embodiment of the self-locking mechanism 3 in the vehicle chassis disclosed in this utility model, the first blocking part 31 may include at least one telescopic member 311. When the first blocking part 31 includes one telescopic member 311, the extension part 32 is provided with two first through holes positioned opposite each other. When the first blocking part 31 includes multiple telescopic members 311, the extension part 32 is provided with multiple first through holes corresponding one-to-one in number and position to the multiple telescopic members 311, and the multiple telescopic members 311 work together to keep the first blocking part 31 in a telescopic or extended state. When the multiple telescopic members 311 are simultaneously in a retracted state, the first blocking part 31 is in a retracted state. When the multiple telescopic members 311 are simultaneously in an extended state, the first blocking part 31 is in an extended state.

[0065] Further, refer to Figure 3 ,exist Figure 3 The following description uses the first blocking part 31, which includes two telescopic members 311, as an example. Correspondingly, the extension part 32 is provided with two first through holes that correspond to the positions of the two telescopic members 311.

[0066] Further, the self-locking mechanism 3 can be considered as a connecting structure or a fixing structure for connecting and fixing the vehicle body panel 1 and the vehicle body frame 2.

[0067] Further, the number of the telescopic members 311 in the first blocking part 31 is not limited in the embodiment, and the number of the telescopic members 311 in the first blocking part 31 of the self-locking mechanism 3 can be determined by the user based on specific requirements and application scenarios of the self-locking mechanism 3.

[0068] Reference Figure 6 and Figure 7 In the vehicle bench disclosed in the embodiment of the utility model, the first blocking part 31 comprises: telescopic member 311 and fixed part 312. Telescopic member 311 comprises: spring 3111 and movable button 3112. The movable end of spring 3111 is connected with movable button 3112, and the fixed end is fixedly connected with fixed part 312. In the case that movable button 3112 is under force, movable button 3112 pushes spring 3111 to shrink, so that movable button 3112 and spring 3111 are shrunk in extension part 32. In the case that movable button 3112 is not under force, spring 3111 pushes movable button 3112 to extend to the outside of extension part 32, so that movable button 3112 extends to the outside of extension part 32 through the first through hole, and the vehicle body panel 1 is clamped and fixed on the vehicle body frame 2 based on movable button 3112 and second blocking part 33.

[0069] Further, in the self-locking mechanism 3 shown in Figure 6 and Figure 7 The first blocking part 31 comprises: first telescopic member and second telescopic member, and the first telescopic member and the second telescopic member both comprise spring 3111 and movable button 3112. The fixed part 312 of the first blocking part 31 is a mounting frame, and the first telescopic member and the second telescopic member are mounted in one mounting frame, for example.

[0070] In the self-locking mechanism 3 shown in Figure 6 and Figure 7 The two ends of the spring 3111 in the first telescopic member and the second telescopic member are fixed end and movable end respectively. That is, one end (movable end) of the spring 3111 is fixedly connected with the movable button 3112, and the other end (fixed end) is fixedly connected with the fixed part 312.

[0071] In the self-locking mechanism 3 based on Figure 6 and Figure 7When the self-locking mechanism 3 is connected to the vehicle body frame 2 and the vehicle body panel 1, the movable buttons 3112 in the first telescopic member and the second telescopic member are simultaneously forced to make the first telescopic member and the second telescopic member simultaneously retract towards the inside of the extension part 32, and when the surface of the movable buttons 3112 in the first telescopic member and the second telescopic member farthest from the spring 3111 is flush with the outer side of the extension part 32, the extension part 32 passes through the vehicle body panel 1 and the vehicle body frame 2, and at this time, the second blocking part 33 does not pass through the vehicle body panel 1 and the vehicle body frame 2.

[0072] If the extension part 32 sequentially penetrates the vehicle body panel 1 and the vehicle body frame 2, when the first through hole on the extension part 32 is on the side of the vehicle body frame 2 away from the vehicle body panel 1, the force applied to the movable buttons 3112 in the first telescopic member and the second telescopic member is removed, so that the movable buttons 3112 rebound based on the rebound force of the spring 3111 to extend to the outside of the extension part 32 through the first through hole, so that the vehicle body panel 1 and the vehicle body frame 2 can be fixed based on the second blocking part 33 and the movable buttons 3112.

[0073] If the extension part 32 sequentially penetrates the vehicle body frame 2 and the vehicle body panel 1, when the first through hole on the extension part 32 is on the side of the vehicle body panel 1 away from the vehicle body frame 2, the force applied to the movable buttons 3112 in the first telescopic member and the second telescopic member is removed, so that the movable buttons 3112 rebound based on the rebound force of the spring 3111 to extend to the outside of the extension part 32 through the first through hole, so that the vehicle body panel 1 and the vehicle body frame 2 can be fixed based on the second blocking part 33 and the movable buttons 3112.

[0074] Further, in the case where the first blocking part 31 only includes one telescopic member 311, and the telescopic member includes a spring 3111, a movable button 3112 and a fixed member 312, the fixed end of the spring 3111 is a point at the center position of the spring 3111, and the telescopic member 311 includes one spring 3111 and two movable buttons 3112, the two movable buttons 3112 are respectively fixedly connected with the two ends of the spring 3111, and the point at the center of the spring 3111 is fixedly connected with the fixed member 312. At this time, the contraction and expansion of the first blocking part 31 are similar to those of the first blocking part 31 including two telescopic members 311 described above, which will not be described here.

[0075] In the vehicle rack disclosed in the embodiment of the utility model, the second blocking part 33 is fixedly arranged at the end of one end of the extension part 32, and is formed as a structure protruding from the outer contour of the extension part 32 in the peripheral direction of the extension part 32.

[0076] Reference Figure 6Further, the second blocking part 33 can be an end part fixedly arranged at one end of the extension part 32, and is formed in a structure protruding the outer contour of the extension part 32 in the peripheral direction of the extension part 32, so that the second blocking part 33 cannot pass through the connecting hole 22 on the vehicle body frame 2 and the vehicle body panel 1 when the extension part 32 passes through the connecting hole 22 on the vehicle body frame 2 and the vehicle body panel 1, so as to fix the vehicle body frame 2 and the vehicle body panel 1 between the second blocking part 33 and the first blocking part 31.

[0077] With reference to Figure 6 Further, when the second blocking part 33 is an end part fixedly arranged at one end of the extension part 32, and is formed in a structure protruding the outer contour of the extension part 32 in the peripheral direction of the extension part 32, the second blocking part 33 can be detachably connected with the extension part 32 based on a bolt or the like, so as to facilitate removing the vehicle body panel 1 from the vehicle body frame 2 based on detaching the second blocking part 33 when the first blocking part 31 is stuck. Further, when the second blocking part 33 and the extension part 32 are detachably connected based on a bolt and a nut, the self-locking mechanism 3 can be used to connect vehicle body panels 1 and vehicle body frames 2 of different thicknesses based on adjusting the height of the nut on the bolt.

[0078] With reference to Figure 6 Specifically, the second blocking part 33 in the self-locking mechanism 3 can be a baffle, and the extension part 32 is fixedly connected with the baffle based on an opening arranged at one end of the extension part 32 away from the first blocking part 31. At this time, in order to prevent the baffle from passing through the connecting hole 22 on the vehicle body panel 1 and the vehicle body frame 2, the area of the baffle is greater than the area of the connecting hole 22 on the vehicle body panel 1 and the vehicle body frame 2. Further, the shape, thickness and material of the baffle can be determined based on specific use scenarios and requirements.

[0079] With reference to Figure 6 When the vehicle bench provided by the utility model is adopted, the second blocking part 33 can be a baffle, and based on the baffle and the first blocking part 31, the vehicle body panel 1 and the vehicle body frame 2 can be clamped between the baffle and the first blocking part 31, so as to fix the vehicle body panel 1 on the vehicle body frame 2, and the baffle is attached to the side of the vehicle body frame 2 or the vehicle body panel 1 away from the first blocking part 31, so that the baffle, the vehicle body frame 2 and the vehicle body panel 1 are tightly attached to each other, and are not prone to dislocation, so that the connection between the vehicle body panel 1 and the vehicle body frame 2 is more stable under the condition of quick detachable or assembly.

[0080] With reference to Figure 8 , Figure 8Another structure diagram of the self-locking mechanism is shown.

[0081] Further, when the second blocking part 33 is in the expanded state, the size of the second blocking part 33 is greater than the size of the connecting hole 22, so that when the first blocking part 31 and the second blocking part 33 are both in the expanded state, the vehicle body panel 1 and the vehicle body frame 2 can be fixed between the second blocking part 33 and the first blocking part 31, so as to fix the vehicle body panel 1 on the vehicle body frame 2.

[0082] Reference Figure 8 In the vehicle rack disclosed in the embodiment of the present application, the second blocking part 33 is in the contracted state through the second through hole and is contracted in the extension part 32, so that the extension part 32 can pass through the connecting hole 22, and in the expanded state, the extension part 32 extends out of the extension part 32 through the second through hole. Further, the second blocking part 33 can also have the same structure as the first blocking part 31, that is, the second blocking part 33 includes the telescopic part 311 and the fixing part 312. Further, the second blocking part 33 includes the spring 3111 and the movable button 3112.

[0083] Reference Figure 8 Further, when the vehicle body panel 1 and the vehicle body frame 2 are connected based on the self-locking mechanism 3, one of the first blocking part 31 and the second blocking part 33 is always in the expanded state, and the other is forced to change the state, that is, to the contracted state, so that the extension part 32 can pass through the vehicle body panel 1 and the vehicle body frame 2, so as to fix the vehicle body panel 1 and the vehicle body frame 2 between the first blocking part 31 and the second blocking part 33.

[0084] Further, when the second blocking part 33 is set to have the same structure as the first blocking part 31, both ends of the self-locking mechanism 3 can make the extension part 32 pass through the connecting hole 22 on the vehicle body panel 1 and the vehicle body frame 2, so that the installer does not need to distinguish the two ends of the self-locking mechanism 3, so as to facilitate the installer to install or remove the vehicle body panel 1 on the vehicle body frame 2.

[0085] Further, in the self-locking mechanism 3, the fixing member 312 is used to fix the first blocking part 31 and / or the spring 3111, so that the spring 3111 can be stretched when subjected to force. Further, the fixing member 312 can be a fixed plate arranged inside the extension part 32 or an open mounting frame fixedly connected with the first through hole on the extension part 32. In the case that the fixing member 312 is the mounting frame, the opening of the mounting frame is aligned with the first through hole, and the fixed end of the spring 3111 is mounted on the side wall of the mounting frame corresponding to the opening; in the case that the fixing member 312 is the fixed plate, the fixed end of the spring 3111 is mounted on the side wall of the fixed plate.
