[0037] Example 1

[0038] See also Figures 1-3 As shown, a body-in-white frame connection structure provided in an embodiment of the present application includes:

[0039] A connecting rod 1, wherein the outer wall of the connecting rod 1 is provided with a groove 11 extending along the axial direction of the connecting rod 1;

[0040] A connecting cap 2, wherein a roll-type elastic member 24 is disposed inside the connecting cap 2, wherein an outer ring of the roll-type elastic member 24 is fixed to an inner wall of the connecting cap 2, and an inner ring of the roll-type elastic member 24 is provided with a connecting piece 21 extending along the axial direction of the connecting cap 2;

[0041] The hood 2 is slidably sleeved on the connecting rod 1 by clamping the connecting piece 21 in the groove 11. The hood 2 rotates to tighten or rebound the rolled elastic member 24. When the rolled elastic member 24 is tightened, the hood 2 and the connecting rod 1 are fixed by the fastener.

[0042] During connection, the connecting rod 1 enters the connecting cap 2, and the connecting piece 21 located in the connecting cap 2 is inserted into the groove 11 at the bottom of the connecting rod 1. The connecting cap 2 slides in the groove 11 to the target position on the connecting rod 1, so that the connecting cap 2 rotates around the connecting rod 1. Since the connecting piece 21 of the inner circle of the rolled elastic member 24 is stuck in the groove 11, the rolled elastic member 24 is gradually tightened, and the distance between the inner circle of the rolled elastic member 24 and the connecting rod 1 is gradually reduced until the inner circle of the rolled elastic member 24 is completely in contact with the connecting rod 1. At this time, the rolled elastic member 24 limits the connecting rod 1. The connecting cap 2 and the connecting rod 1 are fixed by fasteners to complete the fixation of the profile 4 between the connecting rod 1 and the connecting cap 2. When the position of the hood 2 on the connecting rod 1 needs to be changed or the hood 2 needs to be removed, the fastener is removed, and the rolled elastic member 24 automatically recovers under the action of its own elastic force, so that the hood 2 and the connecting rod 1 are loosened, so that the hood 2 can be slid along the groove 11 to other positions on the connecting rod 1 or separated from the connecting rod 1. The use of the rolled elastic member 24 can limit the connecting rod 1, prevent the connecting rod 1 from deviating in the radial direction, increase the contact area with the connecting rod 1, and improve the stability during connection. When the winding state needs to be released, it can be achieved by removing the fastener, which is convenient to operate. In this embodiment, the rolled elastic member 24 is a coil spring.

[0043] See also Figures 1-3 As shown, the connecting rod 1 is also provided with a first through hole 12 which penetrates the connecting rod 1 in the radial direction of the connecting rod 1;

[0044] The hood 2 is also provided with a second through hole 22 penetrating the inner wall of the hood 2;

[0045] Rotate the second through-hole 22 to align with the first through-hole 12, so that the fastener passes through the second through-hole 22 and the first through-hole 12 simultaneously, thereby fixing the connecting cap 2 and the connecting rod 1.

[0046] See Figure 1 As shown, markings 13 are provided at different lengths of the connecting rod 1.

[0047] By setting the markings 13, the relative positions of the connecting cap 2 and the connecting rod 1 can be determined, making it easier to align the second through-hole 22 and the first through-hole 12 for convenient fixing by the fastener. When the lower end of the connecting cap 2 is near the marking, the fastener can pass through the second through-hole 22 and the first through-hole 12 simultaneously.

[0048] See Figure 1 、 3 As shown, a handle 3 is detachably connected to the connecting rod 1 and / or the connecting cap 2.

[0049] Setting the handle 3 increases the operating area, making it easier to rotate the connecting cap 2 and remove the connecting rod 1.

[0050] Embodiment 2

[0051] See Figures 1-5 As shown, an embodiment of the present application provides a white body frame, including a plurality of detachably connected frame assemblies. The connection parts of adjacent frame assemblies adopt profiles 4 with the same mouth shape, and the profiles 4 are connected through a white body frame connection structure.

[0052] Inside each assembly, aluminum alloy profiles 4 with the same mouth shape are used. The profiles 4 can form a shape like a Chinese character 'Ri' or a Chinese character 'Tian'. When forming a shape like a Chinese character 'Ri', the connecting rod 1 passes through the profiles to be connected in sequence, and the part extending outside the profile is installed with the connecting cap 2 and fixed with a fastener; when forming a shape like a Chinese character 'Tian', multiple sets of connection structures are used, and the connecting rod 1 is inserted into the profiles 4 to be connected in the up-down direction and the left-right direction respectively. The part of the connecting rod 1 extending outside the profile 4 is installed with the connecting cap 2 and fixed with a fastener.

[0053] See Figures 4-5 As shown, it further includes a spring 23. The two ends of the spring 23 are respectively abutted against the outer surface of the connecting cap 2 and the profile 4; the connecting rod 1 passes through the profile 4 to be connected and the spring 23 in sequence and is clamped with the connecting cap 2.

[0054] Setting the spring 23 can absorb and buffer external vibrations, ensuring that the connection structure can be more stable.

[0055] See Figures 3-5As shown in the figure, the skeleton assembly includes a floor skeleton assembly 5, a left sidewall skeleton assembly 6, a right sidewall skeleton assembly 7, a front wall skeleton assembly 8, a roof skeleton assembly 9, and a rear wall skeleton assembly 10. The left and right sides of the floor skeleton assembly 5 are respectively connected to the left sidewall skeleton assembly 6 and the right sidewall skeleton assembly 7, the front and rear sides of the floor skeleton assembly 5 are respectively connected to the front wall skeleton assembly 8 and the rear wall skeleton assembly 10, and the tops of the left sidewall skeleton assembly 6, the right sidewall skeleton assembly 7, the front wall skeleton assembly 8, and the rear wall skeleton assembly 10 are all connected to the roof skeleton assembly 9.

[0056] The white body skeleton adopts a new type of aluminum alloy body frame structure. Compared with the traditional skeleton body, it is divided into a floor skeleton assembly 5, a left sidewall skeleton assembly 6, a right sidewall skeleton assembly 7, a front wall skeleton assembly 8, a roof skeleton assembly 9, and a rear wall skeleton assembly 10. The above-mentioned connection structure is adopted between the inside of the skeleton and the skeleton beams, so as to realize the rapid disassembly, adjustment and verification of the white body.

[0057] Embodiment 3

[0058] An embodiment of the present application provides a vehicle, including the above-mentioned white body skeleton.

[0059] The working process of the present utility model is as follows:

[0060] After the connecting piece 21 in the connecting cap 2 is clamped in the groove 11 at the bottom of the connecting rod 1, the connecting cap 2 slides along the groove 11 to the target position on the connecting rod 1. Rotate the connecting cap 2 with the connecting rod 1 as the axis. When the second through hole 22 and the first through hole 12 are aligned, the connecting cap 2 and the connecting rod 1 are fixed by fasteners, and the fixing of the profile 4 located between the connecting rod 1 and the connecting cap 2 can be completed.

[0061] When it is necessary to separate the connecting rod 1 and the connecting cap 2, remove the fasteners and slide the connecting cap 2 to the bottom of the connecting rod 1 and take it out. The overall structure of this connection structure is simple, the installation and disassembly are convenient, and the fixing effect is good.

[0062] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments.
