[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0032] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] In one embodiment;

[0035] See also Figure 1, provides a logistics compartment of an electric tricycle for express delivery, comprising a frame 11, a load-bearing frame plate 12 installed in the frame 11, and a logistics compartment 15 mounted on the load-bearing frame plate 12;

[0036] The logistics compartment 15 is slidably mounted on the carrier plate 12, the frame 11 is provided with a support seat 13, and the carrier plate 12 is mounted on the support seat 13 through a rotating assembly 14;

[0037] The frame 11 is also provided with a limit sliding frame 16, which has a built-in support member 17. A limit member 18 is provided on the side edge of the limit sliding frame 16. The carrier plate 12 is provided with a sliding member 19, which is mounted on the support member 17 and docks with the limit member 18 after movement.

[0038] The present embodiment is applicable to a logistics vehicle of the electric tricycle type, in which the logistics compartment 15 is a small compartment structure; the vehicle frame 11 is connected to a traction vehicle head as a power end, and a load-bearing frame plate 12 is rotatably mounted on the vehicle frame 11, which can drive the load-bearing frame plate 12 to tilt and flip, thereby facilitating the unloading of the logistics compartment 15; the logistics compartment 15 is slidably mounted on the load-bearing frame plate 12, and can be separated from the load-bearing frame plate 12, so that the load-bearing frame plate 12 can tilt toward the vehicle frame 11, making it convenient for the logistics compartment 15 to slide toward the ground and avoid the influence of the wheel height.

[0039] In order to facilitate personnel operation, the present embodiment also designs a limiting sliding frame 16 for limiting the movement of the load-bearing frame plate 12, and the supporting member 17 is used to support the load-bearing frame plate 12. When the load-bearing frame plate 12 moves to the area of ​​the limiting member 18, the sliding member 19 completes the docking with the limiting member 18, and can support and position the load-bearing frame plate 12. In this way, when unloading the logistics compartment 15, a support point can be formed for the load-bearing frame plate 12 to maintain the unloading inclined state, so that a single person can complete the unloading or loading operation of the logistics compartment 15.

[0040] The logistics box 15 and the frame 11 are in a combined structure. Personnel can unload the logistics box 15 and use it directly as a delivery container, which is convenient for couriers to deliver products door to door or receive express mailed by others, thereby facilitating the daily work of couriers.

[0041] In one embodiment;

[0042] The installation structure of the carrier plate 12 and the logistics compartment 15 is specifically designed as follows in this embodiment:

[0043] See also Figure 2 and Figure 3The carrier plate 12 includes a basic frame plate 21, a supporting base plate 22 arranged on the basic frame plate 21, and a sliding track 24 arranged on the side edge of the supporting base plate 22. The basic frame plate 21 is mounted on the rotating component 14; the logistics compartment 15 includes a compartment frame 31, a frame bottom plate 32 arranged at the bottom of the compartment frame 31, positioning support plates 33 arranged at the four corners of the frame bottom plate 32, and a sliding wheel 34 installed on the positioning support plate 33; the logistics compartment 15 is mounted on the supporting base plate 22, and the sliding wheel 34 is embedded in the sliding track 24, so that the supporting base plate 22 forms a limited installation for the logistics compartment 15, which is convenient for the installation and disassembly of the logistics compartment 15 and avoids the problem of shaking of the logistics compartment 15.

[0044] In one case of this embodiment;

[0045] The front edge of the logistics compartment 15 is provided with an inner insert bar 35 , and the support base plate 22 is provided with a connecting recess 23 corresponding to the inner insert bar 35 , so that the spacing of the logistics compartment 15 during loading is positioned.

[0046] In one embodiment;

[0047] The mounting structure of the carrier plate 12 and the frame 11 is specifically designed as follows in this embodiment:

[0048] See also Figure 4 The support seat 13 is provided with a support base 41, a support frame 42 arranged on the support base 41, and support side frames 43 installed on both sides of the support frame 42. The rotating assembly 14 includes a support plate 44 installed on the support side frame 43, and a driving roller 45 mounted between the support plates 44. The side edge of the basic frame plate 21 is installed on the corresponding support plate 44 through a rotating frame 46. The frame 11 is externally provided with a power source for driving the driving roller 45 to move.

[0049] The load-bearing frame plate 12 is installed on the support plate 44 through the bottom base frame plate 21. The frame 11 is equipped with an external motor as a power source to drive the drive roller 45 to move. The drive roller 45 drives the support plate 44 to move, thereby driving the load-bearing frame plate 12 to move and tilt, and then tilt to unload the logistics compartment 15.

[0050] Among them, the driving roller 45 is arranged in the area behind the center line of the frame 11 (with the front of the vehicle as the front), so that when the logistics compartment 15 is placed flat, the gravity is inclined toward the front, which makes the center of gravity of the logistics compartment 15 tend to tilt forward, and the direction of the center of gravity offset is opposite to the unloading direction of the logistics compartment 15, thereby avoiding the risk of the logistics compartment 15 detaching and shaking when the vehicle is moving.

[0051] In one embodiment;

[0052] Regarding the specific installation structure of the carrier plate 12, the present embodiment is designed as follows:

[0053] See also Figure 5 The position-limiting sliding frame 16 includes a supporting base plate 51 mounted on the vehicle frame 11 , an arc-shaped support frame 53 mounted on the supporting base plate 51 , and an arc-shaped track 52 arranged in the arc-shaped support frame 53 , and the sliding member 19 moves along the arc-shaped track 52 .

[0054] See also Figure 6 and Figure 7 The sliding member 19 includes a support block 61 installed on the basic frame plate 21, and a sliding block 62 arranged on the support block 61, the sliding block 62 is installed on the arc track 52, the sliding block 62 is installed with a side block 63, and the side block 63 is provided with a limiting protrusion 64; the limiting member 18 is installed on the side edge of the arc support frame 53, the limiting member 18 includes a combination block 71, and a limiting inner frame 73 arranged on the side edge of the combination block 71, the combination block 71 is provided with a limiting groove 72 matching the limiting protrusion 64, the limiting inner frame 73 is provided with a sliding groove 74, and the sliding groove 74 is installed with a blocking block 75 through a telescopic member 76, the bottom of the blocking block 75 is a slope surface, and the top of the blocking block 75 is a straight plate surface, the telescopic member 76 includes a telescopic rod 81, and a support spring 82 sleeved on the telescopic rod 81, and the support spring 82 is supported between the blocking block 75 and the limiting inner frame 73.

[0055] The bearing frame plate 12 moves along the arc track 52 through the sliding member 19. When the driving roller 45 drives the bearing frame plate 12 to flip and tilt, the sliding member 19 moves up along the arc track 52 and moves until the limiting protrusion 64 collides with the blocking block 75. At this time, the blocking block 75 first contacts the bottom slope of the blocking block 75, thereby pushing the blocking block 75 to retract until the limiting protrusion 64 is inserted into the limiting groove 72. At this time, the blocking block 75 is separated from the limiting protrusion 64, and the supporting spring 82 that has been squeezed before releases its elastic potential energy, pushing the blocking block 75 to reset, and completing the engagement with the limiting protrusion 64, thereby forming a front support point for the bearing frame plate 12. In this way, when the logistics compartment 15 is unloaded, the bearing frame plate 12 forms a fixed tilting trend, thereby avoiding the problem of shaking of the bearing frame plate 12 and the reverse pressure on the driving roller 45, reducing damage to the driving roller 45 and improving safety.

[0056] See also Figure 7The rear edge of the inner limit frame 73 is also provided with an adjustment frame 83, and the adjustment frame 83 has an adjustment cavity 84 built therein. The telescopic rod 81 is externally connected to a pull rod 85 and extends into the adjustment cavity 84. The adjustment cavity 84 is connected to the outer edge of the frame 11, and the pull rod 85 is externally connected to an operating rod 86. When the personnel push the logistics compartment 15 obliquely onto the carrier plate 12, the operating rod 86 drives the pull rod 85 to move along the adjustment cavity 84, thereby pulling the telescopic rod 81, that is, pulling the blocking block 75 to move, so that the blocking block 75 no longer forms a blocking tendency to the limit protrusion 64, and drives the carrier plate 12 to flip downward through the driving roller 45, that is, drives the logistics compartment 15 to reset.

[0057] In one embodiment;

[0058] See also Figure 5 and Figure 8 The support member 17 is arranged in the inner space of the arc-shaped support frame 53, and the support member 17 includes a fixing sleeve 91 installed on the inner side wall of the arc-shaped support frame 53, a supporting spring 92 installed in the fixing sleeve 91, and a supporting cushion block 93 installed on the supporting spring 92; a concave section 94 is arranged between the support block 61 and the sliding block 62, and the supporting cushion block 93 adopts an arc-shaped elastic structure to be supported in the concave section 94.

[0059] A support member 17 with an elastic structure is also provided in the inner space of the arc-shaped support frame 53. The support spring 92 has an arc-shaped elastic force trend along with the arc-shaped support frame 53. As the load-bearing frame plate 12 flips and moves downward, the load-bearing frame plate 12 is mounted on the support member 17. The support spring 92 provides supporting elastic force, and the support pad 93 is inserted into the concave interval 94, thereby forming a relatively stable support point. When the center of gravity of the logistics compartment 15 tends to tilt forward, the logistics compartment 15 is buffered and supported, thereby improving the stability of the vehicle during operation.

[0060] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0061] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
