[0005] The outer side surface of the front box body side panel is provided with a closed ring-shaped groove, and a buffer portion that moves in the width direction is provided in the groove, and the buffer portion is provided on the front box cover side panel;

[0006] A first elastic member arranged on the front box cover end panel is arranged between the front box cover end panel and the front box body end panel.

[0007] The utility model is further configured as follows: a second elastic member arranged on the front box cover side panel is provided between the front box cover side panel and the front box body side panel.

[0008] The utility model is further configured as follows: the cross section of the buffer portion is U-shaped, the buffer portion has a fixed connection portion and a movable connection portion, and the fixed connection portion is connected to the side panel of the front box cover.

[0009] The utility model is further configured as follows: a deformation groove extending along the width direction of the groove is arranged on the circumference of the movable connection part, one end of the deformation groove is connected to the outside, and the other end extends inward.

[0010] The utility model is further configured as follows: the movable connection portion is provided with a blocking portion which abuts against the groove wall of the groove.

[0011] The utility model is further configured as follows: the first elastic member is a spring sheet structure with one end connected to the front box cover end panel and the other end abutting against the front box body end panel.

[0012] The utility model is further configured as follows: the second elastic member is a spring sheet structure with one end connected to the front box cover side panel and the other end abutting against the front box body side panel.

[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. Because the cross section of the buffer part is U-shaped and the movable connection part on the buffer part is provided with deformation grooves, the front box cover body can be quickly snap-fitted and installed on the front box body, which is convenient for assembly.

[0015] 2. When force is applied from the end face, the first elastic member deforms to release the force; when force is applied from the side face, the second elastic member deforms to release the force; when force is applied from the combined end face and side face, the first elastic member and the second elastic member deform simultaneously to release the force, providing reliable buffering and impact resistance.

[0019] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0020] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0021] Example 1

[0022] See also Figure 1 and Figure 2As shown, an impact-resistant front box body of a trolley case involved in this embodiment includes a front box body and a front box cover body, wherein the front box body includes a front box end panel 1 and a front box side panel 2, and the front box cover body includes a front box cover end panel 3 and a front box cover side panel 4, wherein the front box cover side panel 4 is sleeved on the front box side panel 2, and the front box cover end panel 3 is arranged on the front side of the front box end panel 1;

[0023] The outer side surface of the front box body side panel 2 is provided with a closed ring-shaped groove 5, and a buffer portion 6 that moves in the width direction is provided in the groove 5, and the buffer portion 6 is provided on the front box cover side panel 4;

[0024] A first elastic member 7 arranged on the front box cover end panel is provided between the front box cover end panel 3 and the front box body end panel 1; a second elastic member 8 arranged on the front box cover side panel is provided between the front box cover side panel 4 and the front box body side panel 2.

[0025] Furthermore, the cross section of the buffer portion 6 is U-shaped, and the buffer portion 6 has a fixed connection portion 61 and a movable connection portion 62 , and the fixed connection portion 61 is connected to the front box cover side panel 4 .

[0026] Furthermore, a deformation groove 63 extending along the width direction of the groove is arranged on the circumference of the movable connection portion 62, and one end of the deformation groove 63 is connected to the outside, and the other end extends inward.

[0027] Furthermore, the movable connection portion 62 is provided with a blocking portion 64 which abuts against the groove wall of the groove.

[0028] Furthermore, the first elastic member 7 is a spring sheet structure with one end connected to the front box cover end panel and the other end abutting against the front box body end panel.

[0029] Furthermore, the second elastic member 8 is a spring sheet structure with one end connected to the front box cover side panel and the other end abutting against the front box body side panel.

[0030] In this embodiment, since the cross-section of the buffer portion 6 is U-shaped and its rear end is an arc-shaped structure, when the front box cover body is inserted into the front box body, the buffer portion 6 will be inserted into the front box side panel 2. During this period, the movable connection portion 62 will be deformed and expand outward (because the movable connection portion 62 is squeezed and bends toward the fixed connection portion 61), causing the buffer portion 6 to move into the groove 5, so that it moves in the groove 5 along the width direction, and the two (the front box body and the front box cover body) are quickly assembled.

[0031] When the current box body is impacted in the end direction, the front box cover end panel 3 moves closer to the front box body end panel 1, and the first elastic member 7 is compressed and deformed; when the current box body is impacted in the side direction, the front box cover side panel 4 moves closer to the front box body side panel 2, and the second elastic member 8 is compressed and deformed; when the current box body is impacted in the end and side directions, the first elastic member 7 and the second elastic member 8 near the force-bearing position are compressed and deformed, thereby achieving a force release effect.

[0032] The utility model relates to an impact-resistant front box body of a trolley case. The cross section of the buffer part of the front box body is U-shaped, and deformation grooves are arranged on the movable connection part of the buffer part, so that the front box cover body can be quickly snap-fitted and installed on the front box body, and the assembly is convenient. When a force is applied in the end face direction, the first elastic member is deformed to release the force; when a force is applied in the side face direction, the second elastic member is deformed to release the force; when a force is applied in the combined direction of the end face and the side face, the first elastic member and the second elastic member are deformed at the same time to release the force. The utility model has reliable buffering, impact resistance, a small number of components, convenient manufacturing and processing, complete overall functions, and strong practicality.
