[0018] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0019] The following describes the electric tricycle compartment fixing device according to the embodiment of the present invention in conjunction with the accompanying drawings.

[0020] like Figs. 1-3 As shown, the electric tricycle compartment fixing device of the embodiment of the present utility model may include a compartment fixing frame 10 , two limiting blocks 20 and two sets of limiting mechanisms 30 .

[0021] The carriage fixing frame 10 may include two support arms 11 and a plurality of support rods 12, wherein the plurality of support rods 12 are equidistantly distributed and arranged side by side between the two support arms 11. For example, the plurality of support rods 12 may be 2, 3, 4, or 5 support rods 12, and the specific number used may be selected according to actual conditions and is not limited here.

[0022] In the embodiment of the present invention, a plurality of support rods 12 are respectively welded to the two support arms 11 , or one support rod 12 is respectively connected to the two support arms 11 in an integral manner, thereby effectively enhancing the overall strength of the carriage fixing frame 10 .

[0023] It should be noted that the top walls of the multiple support rods 12 described in this embodiment can be flush with the top walls of the two support arms 11, so that the multiple support rods 12 can also support the electric tricycle compartment 40.

[0024] The two support arms 11 each have a chute 101 formed therein. Two stoppers 20 are slidably disposed within the corresponding chute 101. The two stoppers 20 are fixedly connected to the bottom wall of the electric tricycle compartment 40. It should be noted that the chute 101 and stoppers 20 described in this embodiment both have convex cross-sections. Furthermore, the two stoppers 20 can be connected to the electric tricycle compartment 40 by welding.

[0025] The two sets of limiting mechanisms 30 are respectively arranged on the corresponding side walls of the support arm 11 , and the two sets of limiting mechanisms 30 are respectively connected to the corresponding limiting blocks 20 in abutment with each other.

[0026] In one embodiment of the present invention, Figs. 1-3As shown, each set of limiting mechanism 30 can include a plurality of limiting mechanisms 30, which are equidistantly arranged side by side on the side wall of the support arm 11, for example, the plurality of limiting mechanisms 30 can be 2, 3, 4 limiting mechanisms 30, etc., and the specific number of use can be selected according to the actual situation, which is not limited herein. Each limiting mechanism 30 can include a mounting box 31, a chuck 32, a guide rod 33, a drive wrench 34 and a spring 35.

[0027] Wherein, the mounting box 31 is fixedly arranged on the side wall of the support arm 11, the chuck 32 is slidingly arranged in the mounting box 31, and one end of the chuck 32 extends into the sliding groove 101 through the mounting box 31 and the support arm 11 in sequence.

[0028] One end of the guide rod 33 is fixedly connected with the other end of the chuck 32, and the other end of the guide rod 33 extends out of the mounting box 31 and is pivotally connected with the drive wrench 34. It should be noted that the other end of the guide rod 33 is pivotally connected with the drive wrench 34 through a pin shaft in this embodiment.

[0029] It should be noted that the distance from the end of the drive wrench 34 to the pivot point of the drive wrench 34 and the other end of the guide rod 33 is greater than the distance from the pivot point of the drive wrench 34 and the other end of the guide rod 33 to the mounting box 31 in this embodiment.

[0030] The spring 35 is sleeved on the guide rod 33, one end of the spring 35 is fixedly connected with the chuck 32, and the other end of the spring 35 is fixedly connected with the end wall of the mounting box 31.

[0031] Further, in an embodiment of the present application, as shown in Fig. 2 The limiting block 20 is provided with a slope matched with the chuck 32 on both sides of one end close to the head of the electric tricycle compartment 40, and the slope is used to abut against the head of the chuck 32. A plurality of equidistantly arranged grooves 201 are formed in the side wall of the limiting block 20, and the plurality of grooves 201 are respectively matched with the corresponding chucks 32. It should be noted that the number of grooves 201 in this embodiment is the same as the number of limiting mechanisms 30.

[0032] Specifically, when the electric tricycle carriage 40 needs to be installed on the carriage fixing frame 10, the relevant staff first needs to manually drive the two limiting mechanisms 30 near the rear of the electric tricycle carriage 40, that is, the staff manually moves the driving wrench 34 to flip it, and the flipped driving wrench 34 flips from horizontal to vertical with the installation box 31. At this time, the end of the driving wrench 34 contacts the installation box 31. Since the distance from the end of the driving wrench 34 to the pivot point of the driving wrench 34 and the other end of the guide rod 33 is greater than the distance from the pivot point of the driving wrench 34 and the other end of the guide rod 33 to the installation box 31, during the process of flipping the driving wrench 34, the driving wrench 34 pulls the guide rod 33 outward, and the pulled guide rod 33 drives the clamping head 32 to move into the installation box 31 and then moves out of the slide 101.

[0033] Then, the staff can control the crane to lift the electric tricycle car body 40, and then align one end of the two limit blocks 20 welded on the bottom wall of the electric tricycle car body 40 with the chute 101 on the two support arms 11, and make one end of the limit block 20 with the inclined surface face the front of the car. Then, the staff can push the electric tricycle car body 40 to move, so that the two limit blocks 20 at the bottom of the electric tricycle car body 40 are respectively inserted into the corresponding chute 101. When the inclined surfaces on the two limit blocks 20 hit the clamps 32 in the two limit mechanisms 30 near the front of the car, as the limit blocks 20 move, the clamps 32 are pressed toward the installation box 31 and compress the spring 35, and the guide rod 33 pushes the drive wrench 34 away from the installation box 31.

[0034] When the ends of the two limit blocks 20 move to the ends of the slide slot 101 , the groove 201 on the limit block 20 is opposite to the clamping head 32 , and the clamping head 32 is reset under the tension of the spring 35 and inserted into the groove 201 .

[0035] At the same time, the groove 201 of the limit block 20 near the rear end of the electric tricycle car 40 is opposite to the corresponding clamping head 32. At this time, the staff manually turns the driving wrench 34 to reset it. At this time, the clamping head 32 corresponding to the groove 201 is reset and inserted into the groove 201 under the action of the spring 35, thereby realizing the limiting of the two limit blocks 20, thereby fixing the electric tricycle car 40 on the car fixing frame 10.

[0036] When the electric tricycle carriage 40 needs to be removed from the carriage mounting bracket 10, the operator simply moves each corresponding drive wrench 34 to pull the corresponding clamping head 32 out of the groove 201, thereby releasing the restraint on the limit block 20. The operator then pulls the electric tricycle carriage 40, causing the limit block 20 to slide out of the corresponding chute 101, and the electric tricycle carriage 40 can be removed.

[0037] In conclusion, the electric tricycle carriage fixing device can effectively improve the disassembly and assembly efficiency of the carriage and reduce the burden of workers.
