Description

Technical Field

[0001] This utility model relates to the field of grass combing machine technology, and in particular to a battery pack mounting structure and a grass combing machine using the same. Background Technology

[0002] Lawn demarcation machines effectively remove dead grass, moss, and weeds from lawns, promoting healthy lawn growth and maintaining the lawn's appearance. To meet the requirements of modern landscaping operations for convenience, environmental friendliness, and low noise, electric lawn demarcation machines powered by rechargeable battery packs are gradually becoming the mainstream choice in the market. As the energy core of electric lawn demarcation machines, the reliability, convenience, and safety of the battery pack's installation structure are of paramount importance.

[0003] Traditional battery pack installation methods often employ simple plug-in or snap-fit ​​fixing. The battery pack is inserted directly into the equipment compartment from above, relying on its own weight and simple plastic clips for fixation, thus connecting the battery pack's power contacts to the comb's power contacts. However, during comb operation, the machine body generates continuous and severe vibrations. Due to the lack of restraints and the simple clip structure, the battery pack is prone to fatigue and even breakage under prolonged vibration. This can lead to loosening of the power contacts, causing power outages, sparking, and arcing, affecting not only work efficiency but also posing serious safety hazards. Furthermore, the battery itself relies on gravity to descend and rigidly contact the bottom of the compartment during installation, making it susceptible to damage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a battery pack installation structure and a hay combing machine using the same, which solves the problems of unstable battery installation and easy damage during installation in existing hay combing machines.

[0005] On the one hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution: A battery pack mounting structure for mounting a battery body, comprising: Warehouse body; The power supply board is installed on the side of the compartment, and both ends of the power supply board are equipped with limit blocks to form a sliding groove with the power supply board.

[0022] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] This utility model embodiment proposes a battery pack mounting structure for mounting the battery body 4, including: Container 2; Power supply board 7 is installed on the side of the compartment 2, and both ends of the power supply board 7 are provided with limiting blocks 702 to form a sliding groove 703 with the power supply board 7. The mounting shell 5 is installed on the battery body 4. There are mounting strips 503 on both sides of the mounting shell 5. The two mounting strips 503 are slidably engaged with the two sliding grooves 703 respectively. The fastener is slidably mounted on the mounting shell 5. The power supply board 7 has a slot 701. The fastener is snapped into the slot 701 to fix the battery body 4 to the power supply board 7. An elastic element is located at the bottom of the compartment 2 and abuts against the bottom of the battery body 4.

[0024] In the embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 5As shown, the mounting shell 5 is integrated into the side of the battery body 4 as one of the assembly structures of the battery body 4. At the same time, the power supply contacts of the battery body 4 are located inside the mounting shell 5. The power supply board 7 not only has a limiting block 702, but also has power supply contacts for power supply. The contact positions correspond to the power supply contacts of the mounting shell 5. When installing the battery body 4, the mounting strip 503 of the mounting shell 5 is aligned with the slide groove 703 one by one and can be slid in directly. Through the cooperation of the mounting strip 503 and the slide groove 703, precise guidance and initial positioning are achieved during battery pack installation.

[0025] After the mounting strip 503 is installed in the slide groove 703, the power supply contacts of the battery body 4 are connected to the power supply contacts of the power supply board 7. At this time, the fixing piece inside the mounting shell 5 can be slid directly to engage with the slot 701 on the power supply board 7. The slot 701 and the fixing piece achieve vertical positioning of the battery body 4, while the mounting strip 503 and the slide groove 703 achieve lateral positioning of the battery body 4. This dual-stage fixing mechanism prevents the battery body 4 from loosening or coming out vertically and laterally, effectively resisting the continuous and severe vibrations generated during the operation of the brush comb, and ensuring the stability of the battery body 4 during the operation of the brush comb. The aforementioned fixing piece can be fixed by bolts or by pins.

[0026] Because the battery body 4 is installed from top to bottom, the elastic element, in conjunction with other elastic components, can absorb and buffer most of the impact energy of the battery body 4, reducing the risk of damage to the battery body 4 due to rigid impacts. The aforementioned elastic element can be a spring, a sheet, or other types of elastic structure.

[0027] Specifically, the structure of the fastener is optimized, such as... Figure 5 As shown, the fixing member is a locking block 501, which is slidably disposed on the mounting shell 5. When the locking block 501 protrudes from the surface of the mounting shell 5, it is locked into the slot 701.

[0028] The locking block 501 adopts a block structure with a rectangular cross-section. When the locking block 501 slides out and is embedded in the slot 701 of the power supply board 7, it can directly achieve rigid interlocking and withstand a very large pull-out force. At the same time, the locking block 501 has a guide slope 504 on the side near the surface of the mounting shell 5. When the battery body 4 is pushed in along the slide groove 703, when the locking block 501 with the guide slope 504 contacts the edge of the power supply board 7 during the sliding process, the thrust generated by the slope will automatically press the locking block 501 back into the mounting shell 5. After the battery body 4 is installed, the locking block 501 can be pushed back to lock into the slot 701, which simplifies the operation steps.

[0029] To facilitate operation of the card block 501, a button 502 is slidably provided on the top of the mounting shell 5. The button 502 is connected to the card block 501. When the operator holds the battery body 4, his thumb can naturally rest on the button 502 in the top area, making it convenient to operate the card block 501.

[0030] Furthermore, to further simplify the installation of the battery body 4, a spring is provided on the side of the button 502 near the battery body 4. The position of the spring is not shown in the diagram. It is located inside the button 502. The button 502 can be subjected to the continuous force of the spring, causing the locking block 501 to protrude from the surface of the mounting shell 5. When the battery body 4 is pressed down and the locking block 501 is pushed back, when the locking block 501 is aligned with the slot 701, the locking block 501 can automatically spring into the slot 701 under the pressure of the spring to achieve locking, so that it does not need to be manually pushed in, which is convenient for operation. At the same time, under the action of the spring, the stability of the locking block 501 in the slot 701 can also be guaranteed.

[0031] Specifically, the structure of the elastic element is optimized, such as... Figure 4 As shown, the elastic component includes two mounting sections 6, two elastic sections 601 located at the ends of the two mounting sections 6, and a receiving section 602 located between the two elastic sections 601. The receiving section 602 has an angle with the mounting section 6. Through the double-bending beam structure formed by the two mounting sections 6, the two elastic sections 601, and the receiving section 602, when the battery body 4 is installed and the receiving section 602 is pressed down, the two elastic sections 601 will deform simultaneously. The impact force is transmitted to the two symmetrical elastic sections 601 through the receiving section 602, and then distributed to the two mounting sections 6, making the force distribution more uniform and greatly improving the durability and resistance to metal fatigue of the elastic component itself.

[0032] To facilitate the installation of the elastic element, a fixing cylinder 202 is provided at the bottom of the chamber 2, and the installation section 6 passes through the fixing cylinder 202. During assembly, the operator only needs to align the installation section 6 of the elastic element with the hole in the fixing cylinder 202 and insert it, which is convenient for assembly.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the battery pack installation structure also includes a cover plate 3. The end of the cover plate 3 is provided with a connecting seat 301. The compartment 2 has an installation groove 201. The connecting seat 301 is rotatably disposed in the installation groove 201. After the battery body 4 is installed, the cover plate 3 seals it inside the compartment 2, forming an effective protective barrier. This not only prevents the operator's hands, clothes or foreign objects from accidentally touching the battery body 4, but also effectively blocks dust, grass clippings, rainwater and other pollutants from entering the compartment 2 and contaminating the battery body 4.

[0034] Furthermore, an elastic block 302 is provided at the end of the cover plate 3 away from the connecting seat 301, and the compartment 2 has an installation port 203 corresponding to the elastic block 302. The elastic block 302 can be an elastic snap-fit ​​structure that is snapped into the installation port 203 by its own elastic deformation, or it can be a rectangular elastic block that is fixed in the installation port 203 by interference fit to fix the cover plate 3.

[0035] like Figure 1 As shown in the figure, this utility model embodiment also proposes a grass comber, including a housing 1, characterized in that it further includes the above-mentioned battery pack mounting structure, which is mounted on the housing 1. The specific structure of the battery pack mounting structure is as described in the above embodiment. Since this grass comber adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
