Technical Field

[0001] The utility model belongs to the field of tricycle accessories, and particularly relates to a rear compression package of a side-drive tricycle with a switchable driving mode. Background Technique

[0002] With the improvement of environmental awareness and the aggravation of urban traffic congestion, electric tricycles have been widely used in the fields of logistics distribution, short-distance transportation, etc. due to their characteristics of low carbon environmental protection, flexibility and convenience. However, when the electric tricycle is fully loaded with goods and going uphill, it is easy to slow down or even unable to continue driving due to insufficient torque, which limits its scope of use.

[0003] Currently, the common solutions on the market mainly include two methods: increasing the battery capacity and motor power, and installing an external assistance system. Although the former can effectively improve the cruising range and climbing ability, it also increases the vehicle weight and cost at the same time; the latter provides additional power support through a hydraulic pump or a pneumatic pump, etc., with a high maintenance cost and a large occupied space, which is not conducive to the overall layout design of the vehicle. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to add a motor or a hydraulic pump to improve the passability of the tricycle, with relatively high maintenance and use costs.

[0005] To solve the above problems, the following technical solutions are adopted in the utility model: The rear compression package of the side-drive tricycle with a switchable driving mode proposed by the utility model includes a first rear compression package housing, a connecting cylinder is fixedly arranged on the side of the first rear compression package housing, a second rear compression package housing is movably connected to the first rear compression package housing, and the first rear compression package housing and the second rear compression package housing are connected by bolts. It also includes a first transmission shaft, a transmission mechanism, a limiting mechanism and an adjusting mechanism. One end of the first transmission shaft is rotatably connected to the first rear compression package housing and penetrates through the first rear compression package housing. The other end of the first transmission shaft is rotatably connected to a second transmission shaft, and the second transmission shaft is rotatably connected to the inner side of the second rear compression package housing.

The limiting mechanism includes a limiting sleeve, the inner side of the limiting sleeve is slidably and fittingly connected to the outside of the second transmission shaft, and the outer ring of the limiting sleeve is slidably and fittingly connected to the other end of the first transmission shaft. The adjusting mechanism is movably connected to the limiting sleeve.

[0006] Further, the transmission mechanism includes a driving shaft and a driving bevel gear, and the driving shaft is rotatably connected to the connecting cylinder and penetrates through the connecting cylinder.

[0007] Further, a driven bevel gear is fixedly arranged on the outside of the first transmission shaft, a driving bevel gear is fixedly arranged at one end of the driving shaft, and the driving bevel gear and the driven bevel gear are meshed with each other.

[0008] Furthermore, the limiting mechanism further includes a first limiting block. A first limiting groove is provided at the other end of the first transmission shaft. The first limiting block is fixed on the outer ring of the limiting sleeve, and the first limiting block and the first limiting groove are slidably and fittingly connected.

[0009] Furthermore, a second limiting block is fixed on the outside of the rotational connection between the second transmission shaft and the first transmission shaft. A second limiting groove is provided inside the limiting sleeve, and the second limiting groove and the second limiting block are slidably and fittingly connected.

[0010] Furthermore, the length of the second limiting block is longer than that of the second limiting groove, and the length of the first limiting groove is equal to that of the first limiting block.

[0011] Furthermore, the adjusting mechanism includes a connecting rod and a clamping sleeve. The clamping sleeve has a semi-circular ring structure.

[0012] Furthermore, the connecting rod is rotatably connected to the inner side of the second rear press package housing. One end of the connecting rod penetrates through the second rear press package housing and is threadedly connected with a dial rod.

[0013] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0014] For the rear press package of the belt-side drive tricycle with a switchable drive mode proposed in this solution, by setting the first transmission shaft and the second transmission shaft to be rotatably connected, arranging a limiting mechanism at the connection of the first transmission shaft and the second transmission shaft, and setting the clamping sleeve to be clamped with the limiting sleeve, the clamping sleeve is used to toggle the limiting sleeve, so as to adjust whether the first transmission shaft and the second transmission shaft are clamped.

[0021] The accompanying drawings are used to provide a further understanding of the present invention and form a part of the description. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0023] As Figures 1-5 As shown, a rear compression package of a belt-side drive tricycle with a switchable drive mode proposed by the present invention includes a first rear compression housing 1. A connecting cylinder 102 is fixedly provided on the side of the first rear compression housing 1. A second rear compression housing 101 is movably connected to the first rear compression housing 1. The first rear compression housing 1 and the second rear compression housing 101 are connected by bolts. It also includes a first transmission shaft 2, a transmission mechanism 4, a limiting mechanism 5, and an adjusting mechanism 6. One end of the first transmission shaft 2 is rotatably connected to the first rear compression housing 1 and penetrates the first rear compression housing 1. The other end of the first transmission shaft 2 is rotatably connected to a second transmission shaft 3. The second transmission shaft 3 is rotatably connected to the inner side of the second rear compression housing 101. The transmission mechanism 4 is connected to the first transmission shaft 2. The limiting mechanism 5 is provided at the connection between the first transmission shaft 2 and the second transmission shaft 3. The limiting mechanism 5 includes a limiting sleeve 501. The inner side of the limiting sleeve 501 is slidably and fittingly connected to the outside of the second transmission shaft 3. The outer ring of the limiting sleeve 501 is slidably and fittingly connected to the other end of the first transmission shaft 2. The adjusting mechanism 6 is movably connected to the limiting sleeve 501.

[0024] As Figures 1-4 As shown, the transmission mechanism 4 includes a driving shaft 401 and a driving bevel gear 402. The driving shaft 401 is rotatably connected to the connecting cylinder 102 and penetrates the connecting cylinder 102. A driven bevel gear 403 is fixedly provided on the outside of the first transmission shaft 2. A driving bevel gear 402 is fixedly provided at one end of the driving shaft 401. The driving bevel gear 402 and the driven bevel gear 403 are meshed.

[0025] As Figures 1-3 shown, the limiting mechanism 5 further includes a first limiting block 502. The other end of the first transmission shaft 2 is provided with a first limiting groove 503. The first limiting block 502 is fixedly arranged on the outer circle of the limiting sleeve 501. The first limiting block 502 and the first limiting groove 503 are in sliding fit connection, which is used for limiting and connecting the limiting sleeve 501 and the first transmission shaft 2. The outer side of the rotating connection part between the second transmission shaft 3 and the first transmission shaft 2 is fixedly provided with a second limiting block 505. The inner side of the limiting sleeve 501 is provided with a second limiting groove 504. The second limiting groove 504 and the second limiting block 505 are in sliding fit connection, which is used for limiting and connecting the limiting sleeve 501 and the second transmission shaft 3. The length of the second limiting block 505 is longer than that of the second limiting groove 504, and the length of the first limiting groove 503 is equal to that of the first limiting block 502.

[0026] As Figures 1-5 shown, the adjusting mechanism 6 includes a connecting rod 602 and a clamping sleeve 603. The clamping sleeve 603 has a semi-circular ring structure. Clamping blocks 604 are arranged at both the upper and lower ends of the clamping sleeve 603. The clamping blocks 604 are clamped with the outer circle of the limiting sleeve 501. The connecting rod 602 is clamped with the clamping sleeve 603 and penetrates through the clamping sleeve 603. The connecting rod 602 is rotatably connected to the inner side of the second rear pressure package housing 101. One end of the connecting rod 602 penetrates through the second rear pressure package housing 101 and is threadedly connected with a dial rod 601.

[0027] During specific use, the driving shaft 401 is passed through the connecting cylinder 102 and sleeved inside the first rear pressure package housing 1. The first transmission shaft 2 is sleeved inside the first rear pressure package housing 1 until the driven bevel gear 403 and the driving bevel gear 402 are in fitting connection. The second limiting groove 504 inside the limiting sleeve 501 is aligned with the second limiting block 505 and then sleeved on the connection part between the second transmission shaft 3 and the first transmission shaft 2. The clamping sleeve 603 is clamped on the limiting sleeve 501. The second rear pressure package housing 101 is sleeved on the second transmission shaft 3. At the same time, the connecting rod 602 is sequentially passed through the second rear pressure package housing 101 and the clamping sleeve 603 and is clamped with the clamping sleeve 603. Then the dial rod 601 is threadedly and firmly connected to one end of the connecting rod 602 to complete the installation. The structure is simple and the installation is convenient.

[0028] When the driving shaft 401 rotates, the first transmission shaft 2 can be driven through the transmission of the driving bevel gear 402 and the driven bevel gear 403. When it is necessary for the second transmission shaft 3 and the first transmission shaft 2 to rotate synchronously, the shift lever 601 is toggled to drive the connecting rod 602 to rotate. Under the limitation of the second rear housing 101, the clamping sleeve 603 drives the limiting sleeve 501 to move until the first limiting block 502 is aligned with the first limiting groove 503 and slides into it. At this time, the first limiting block 502 and the first limiting groove 503 are in a fitted connection, and the second limiting groove 504 and the second limiting block 505 are in a fitted connection. At this time, while the driving shaft 401 controls the rotation of the first transmission shaft 2, it can drive the second transmission shaft 3 to rotate under the limitation of the limiting sleeve 501. Changing the single-wheel drive to a two-wheel drive mode is convenient. When driving on ordinary roads, using single-wheel drive has lower power consumption. When adjusting to two-wheel drive on uphill muddy roads, the torque is greater, and the mechanical structure is simple and the use cost is low.

[0029] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
