Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a connecting mechanism and an energy storage power supply thereof, and a lawn mower. Background Art

[0002] The energy storage power supply on the lawn mower is used to store electric energy, and the energy storage power supply is used to provide electric power to corresponding components on the lawn mower.

[0003] In existing lawn mowers, the energy storage power source is usually connected to the frame of the lawn mower using fasteners. Although this connection method is stable, it is cumbersome to disassemble.

[0004] In addition, the frame position on the lawn mower is limited, and the energy storage power supply can only be positioned and connected at a set position. When the energy storage power supply is too large, it may cause the energy storage power supply to be unable to be connected to the set installation position, and its applicability is relatively poor. Summary of the invention

[0005] The purpose of the utility model is to provide a connecting mechanism with high applicability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A connecting mechanism, a lawn mower includes a frame, and an energy storage power supply is connected to the frame. The characteristic is that the connecting mechanism is arranged between the frame and the energy storage power supply, and includes a base plate, a base, a positioning block and a pre-tightening assembly. The above-mentioned base plate is in the shape of a long plate, and has a positioning groove opened along its width direction. The lower part of the above-mentioned base has a connecting part matching the positioning groove and the connecting part is embedded in the positioning groove. The upper part of the above-mentioned base is used for fixing the energy storage power supply and the base is located in the middle part of the base. The lower part of the above-mentioned positioning block is connected to the end of the positioning groove. The above-mentioned pre-tightening assembly is connected to the upper part of the positioning block and the pre-tightening assembly is against the side of the base.

[0008] In the connection mechanism, the base plate is fixedly connected to the frame of the lawn mower, and the base is fixedly connected to the lower part of the energy storage power supply.

[0009] The connecting mechanism is located between the base plate and the base.

[0010] Specifically, the base is connected to the positioning groove through the connection part of the lower part. Since the positioning groove is arranged along the width direction of the substrate, the base can be connected to the substrate after it is displaced along the width direction of the substrate during installation.

[0011] After the lower part of the positioning block is connected to the end of the positioning groove, the positioning block can be adjacent to the base. The pre-tightening assembly on the positioning block abuts against the side of the base, and such a structure can stably position and connect the base to the base plate.

[0012] In the above-mentioned connection mechanism, the positioning groove is a dovetail groove, the lower part of the positioning block is a connecting end 1 that matches the positioning groove, and the connecting end 1 of the positioning block is embedded at the end of the positioning groove.

[0013] Since the lower part of the positioning block has a connecting end 1 that matches the dovetail-shaped positioning groove, the positioning block can be stably connected to the base plate through the connecting end 1.

[0014] In the above connection mechanism, the preload assembly includes a pressure rod, a contact tube and a second connection end of the upper part of the positioning block in a cylindrical shape. The pressure rod is connected at the second connection end, and the contact tube is sleeved on the pressure rod and abuts against the side of the base.

[0015] The inner end of the pressure rod is connected to the second connecting end of the positioning block, and the outer end of the pressure rod is connected to the contact tube. The flexible contact tube is wrapped around the outer end of the pressure rod. Since the outer diameter of the contact tube is larger than the outer diameter of the pressure rod, the flexible contact tube can limit the movement of the base after contacting the base.

[0016] Of course, the base and the base plate can be connected together relatively stably. The pre-tightening component plays a further limiting role to ensure the stability of the connection between the base and the base plate.

[0017] In the above-mentioned connection mechanism, the number of the positioning blocks is two, and the two positioning blocks are arranged front and back along the length direction of the base plate, and the two ends of the above-mentioned pressure rod are respectively connected to the second connection ends of the corresponding positioning blocks.

[0018] The two ends of the pressure rod are respectively connected to the corresponding positioning blocks. Such a structure can position the pressure rod stably, and finally make the contact cylinder stably contact with the side of the base.

[0019] In the above connection mechanism, the contact cylinder is made of rubber material and two ends of the contact cylinder are respectively against between two positioning blocks.

[0020] The rubber contact sleeve protects the sides of the base from being physically touched.

[0021] In the above-mentioned connection mechanism, the upper portion of the second connection end has a notch.

[0022] The positioning block is made of plastic material and is an integrated structure. The second connecting end has a notch to enable the pressure rod to be stably connected to the positioning block.

[0023] In the above-mentioned connecting mechanism, the above-mentioned positioning block and the pressure rod and contact cylinder located between the two positioning blocks form a positioning unit. There are two positioning units, which are respectively located on both sides of the base, and the contact cylinders on the two positioning units respectively abut against both sides of the base.

[0024] The two positioning units can further improve the connection stability between the base and the base plate.

[0025] The above-mentioned connection mechanism also includes a block-shaped transition connection block, the upper part of which has a recessed notch, and the above-mentioned connection part located at the lower part of the transition connection block also includes a wedge, and the above-mentioned connection part is embedded in the positioning groove.

[0026] Selecting a transition connection block with a corresponding height size can change the initial height of the base, thereby making the mechanism adaptable to different batteries.

[0027] In the above-mentioned connection mechanism, the number of the above-mentioned transition connection blocks is several, and the several transition connection blocks are evenly distributed along the length direction of the base plate.

[0028] A plurality of transition connection blocks can improve the connection stability between the base and the base plate.

[0029] Compared with the prior art, the connection mechanism can change the left and right position and the front and back position of the base on the base plate, so batteries of different sizes and models can be connected to the frame of the lawn mower, and its applicability is relatively high.

[0030] At the same time, the pre-tightening component can further improve the connection stability between the base and the base plate. Since the two pre-tightening components are respectively located on both sides of the base, the entire mechanism structure is relatively compact and has high practical value.
