Description

TECHNICAL FIELD

[0001] The utility model relates to single person load transportation technical field, especially a kind of multi-point multi-angle adjustment with power-assisted cycle. BACKGROUND

[0002] The power-assisted cycle is a portable power-assisted equipment designed for single soldier / single person load, mainly used for material transportation, equipment traction or wounded evacuation in complex terrain (such as mountain, jungle, urban ruins, etc.). Its core requirements are lightweight, angle adjustment, environmental adaptability and comfort, and it needs to be transported conveniently. Especially in terms of angle adjustment, it needs to ensure that the vehicle posture can quickly adapt to terrain changes, quickly complete the adjustment or storage of multiple angles of the power-assisted cycle, reduce the physical consumption of the user and improve the task efficiency.

[0003] At present, various power-assisted cycles are applied in fire fighting, military, transportation, search and rescue and other fields, and these power-assisted cycles more or less have angle adjustment mechanisms, but the angle adjustment strategies are not the same. Common ones include motor-driven adjustment mechanism, hydraulic adjustment mechanism, manual block gear locking mechanism, etc. For example, the motor-driven adjustment mechanism disclosed in Chinese patent CN 113173043 B uses a servo motor to drive a lead screw structure, and the angle of the vehicle body part is adjusted by controlling the motor operation through a handle button. The hydraulic adjustment mechanism disclosed in Chinese patent CN 2880570Y automatically adapts to the terrain angle changes by using the extension and retraction characteristics of the hydraulic cylinder or hydraulic rod, realizes the inclination angle adjustment based on hydraulic feedback, and controls the hydraulic valve to realize dynamic balance by transmitting signals under different terrains through a pressure sensor. The manual block gear locking mechanism disclosed in Chinese patent CN 219927713U adjusts and fixes the angle of the frame and chassis through gear engagement and block structure.

[0004] The above angle adjustment mechanisms can adjust the working angle of the power-assisted cycle to a certain extent, but there are some problems in actual use: for example, the unreasonable distribution of battery power due to the serious dependence on battery power supply makes the battery have insufficient endurance in long-term tasks in the wild, which cannot power other more important work modules, thereby reducing the working efficiency of the power-assisted cycle, and the motor is also prone to failure due to sand and rain erosion, thereby increasing the cost; the hydraulic system generally has large weight, occupies more space, and is complex to maintain, and is prone to leakage or response delay in low temperature or high impact environment, and the later maintenance cost is relatively high; the block fixed locking cannot guarantee sufficient pre-tightening force to tighten the gear, and the gear is located at the connection rotating part of the chassis and the frame, which bears too much force and is prone to gear face fatigue failure and gear tooth fracture. The above problems are more obvious in emergency situations, so it cannot meet the requirements of single soldier / single person for quick adjustment of vehicle posture in complex terrain and environment.

[0033] The preferred embodiments of the utility model are described in detail below in combination with the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0034] The embodiments of the utility model include:

[0035] Embodiment 1

[0036] As shown in the accompanying drawings Figure 1 and 2 The utility model discloses a multi-site multi-angle adjusting follow-up power-assisted vehicle, which comprises a frame body 100, a traction mechanism 200, a first angle adjusting mechanism 300 and two second angle adjusting mechanisms 400.

[0037] The frame body 100 comprises a chassis 110 and a support frame 120.

[0038] The support frame 120 comprises two vertically arranged support rods 121 and a cross rod 122 connected with the two support rods, and the support rod 121 and the cross rod 122 form a U-shaped structure.

[0039] The top end of the support frame 120, i.e. the horizontal rod 122, is connected with the traction mechanism 200 through the first angle adjusting mechanism 300, and the angle between the traction mechanism 200 and the support frame 120 is adjusted through the first angle adjusting mechanism 300.

[0040] The bottom end of the support frame 120, i.e. the bottom end of the two support rods 121, is connected with the bottom disc 120 through the two second angle adjusting mechanisms 400, and the angle between the support frame 120 and the bottom disc 110 is adjusted through the second angle adjusting mechanism 400.

[0041] Specifically, the traction mechanism 200 comprises a traction rod 210, a steering mechanism 220 and a telescopic mechanism 230.

[0042] The steering mechanism 220 and the telescopic mechanism 230 are installed on the traction rod 210 at intervals, one end of the traction rod 210 connected with the first angle adjusting mechanism 300 is a connecting end, and the connecting end is provided with a hollow ring, and the other end is provided with a waist plate 240.

[0043] As shown in the accompanying drawings, the first angle adjusting mechanism 300 comprises a fixed seat 310, a gear shaft 320, a fixed gear 330, a movable gear 340 and a spring 350, and the fixed gear 330, the movable gear 340 and the spring 350 constitute an elastic adjusting assembly. Figure 3 The fixed seat 310 is installed on the horizontal rod 122 of the support frame 120. A first bearing seat 360, a second bearing seat 370 and a baffle plate 380 are vertically installed on the surface of the fixed seat 310 at intervals, and a deep groove ball bearing 390 is installed in each of the first bearing seat 360 and the second bearing seat 370.

[0044] The elastic adjusting assembly is installed between the second bearing seat 370 and the baffle plate 380. Specifically, one end of the fixed gear 330 is fixedly connected with the side surface of the second bearing seat 370, the other end is meshingly connected with the movable gear 340, and the spring 350 is arranged in compression between the movable gear 340 and the baffle plate 380.

[0045] The traction rod 210 of the traction mechanism 200 extends into the first bearing seat 360 and the second bearing seat 370 with the connecting end.

[0046]

[0047] ​One end of the gear shaft 320 passes sequentially through the baffle 380, the movable gear 340, the fixed gear 330, the first bearing seat 360, and the deep groove ball bearing 390 within the second bearing seat 370. The gear shaft 320 also passes through the connecting end of the traction rod 210 and is fixedly connected to the connecting end of the traction rod 210 via a spline. The other end of the gear shaft 320 has an adjusting wrench 321, which is located outside the baffle 380 and is movably locked onto the baffle 380. By loosening or tightening the adjusting wrench 321, the spring 350 can be decompressed or compressed, thereby adjusting the angle between the traction rod 210 and the crossbar 122, and thus adjusting the traction direction of the traction mechanism 200.

[0048] Specifically, when the user needs to adjust the angle between the traction mechanism 200 and the support frame 120, the adjusting wrench 321 can be loosened. At this time, the spring 350 is released from its compressed state. Rotating the adjusting wrench drives the fixed gear 330 and the movable gear 340 to mesh and rotate, thereby driving the traction rod 210 to rotate. When the appropriate angle is adjusted, the adjusting wrench 321 is pressed tightly. At this time, the spring 350 enters a compressed state. The spring has high stiffness, and the radial force it provides can lock the two gears together, preventing them from loosening during operation.

[0049] As attached Figure 4 As shown, the second angle adjustment mechanism 400 includes a connecting block 410, a connecting seat 420, and an angle adjustment bar 430.

[0050] The connecting block 410 has a cuboid structure with a blind hole at its top and a connecting ring (not shown) at its bottom; the support rod 121 of the support frame 120 is inserted into the blind hole.

[0051] The connecting seat 420 is bolted to the chassis 110. The connecting seat 420 includes a base plate 421 and ear seats 422 symmetrically arranged on the base plate. The ear seats are connected by a connecting rod (not shown) that passes through the connecting ring at the bottom of the connecting block 410, so as to realize the rotational connection between the connecting seat 420 and the connecting block 410.

[0052] The chassis 110 has multiple threaded holes on both sides, including five closely spaced threaded holes 111 and four widely spaced threaded holes 112. The spacing between the widely spaced threaded holes 112 is 1.5 to 3 times the spacing between the closely spaced threaded holes 111. The closely spaced threaded holes 111 and the widely spaced threaded holes 112 provide multiple options for the vehicle's angle adjustment. The closely spaced threaded holes 111 allow for fine angle adjustment, while the widely spaced threaded holes 112 allow for coarse angle adjustment, fully meeting the needs of different angles in different environments and improving the vehicle's environmental adaptability.

[0053] The two ends of the angle adjusting strip 430 are provided with fastening screw holes 431, which are respectively connected with the screw holes on the two sides of the connecting block 410 and the bottom plate, so that the connecting block 410, the connecting seat 420 and the angle adjusting strip 430 form an angle-adjustable triangular structure, which stably supports the vehicle body.

[0054] Further, the angle adjusting strip 430 is provided with a plurality of first through holes 432, which are used for realizing the light weight of the angle adjusting strip.

[0055] In addition, the scooter further comprises a control unit 500 and a hub 600.

[0056] The multi-site multi-angle adjusting scooter has the following advantages.

[0057] 1. The angle adjusting mechanism can simplify the components of angle adjustment and realize sufficient light weight of the mechanism, so that the bearing strength is ensured while the cost is reduced.

[0058] 2. The design of the angle adjusting mechanism at two sites realizes multi-angle adjustment at multiple sites, and is more suitable for complex environmental changes.

[0059] 3.
