Description

Technical Field

[0001] This utility model relates to the field of lead-acid batteries, specifically a leak-proof lead-acid battery. Background Technology

[0002] Lead-acid batteries are a type of chemical power source that uses the electrochemical reaction of lead and its oxides to store and release electrical energy. They are typically composed of positive and negative plates, a separator, an electrolyte, and a casing, and are widely used in automotive starting, uninterruptible power supplies, emergency lighting, electric bicycles, and other fields.

[0003] The publication number CN211858825U discloses a lead-acid battery, including a battery body, a cover fixed to the upper end of the battery body, a first groove formed at the upper end of the cover, a liquid filling tube of the battery body extending through the cover into the first groove, and an inner plate placed in the first groove.

[0004] The aforementioned lead-acid batteries can prevent excessive electrolyte from dripping onto the vehicle body or battery rack and causing corrosion when the vehicle is driven on a road with poor conditions. However, during venting, some liquid is easily discharged, which is inconvenient to collect. Furthermore, external objects can easily scratch or puncture the battery body, reducing its protective and heat dissipation effects. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This lead-acid battery, by setting a sealing component, when some liquid is discharged through the safety valve, can collect the discharged liquid through the cavity to prevent liquid from leaking to the outside and causing pollution and corrosion. Through the exhaust pipe, the guide rod drives the sealing cover and sealing plug to slide up and down, which can facilitate the discharge of gas inside the top cover and prevent liquid from being discharged.

[0016] 2) This lead-acid battery, by setting up protective components, a protective cover and a heat-conducting plate fixed to the outside of the battery body, can absorb the heat of the battery body through the heat-conducting plate, improve the heat dissipation of the battery body surface, and at the same time enhance the protection of the battery body and reduce external scratches and punctures.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A leak-proof lead-acid battery includes a battery body 1, a sealing component 2 installed on the top of the battery body 1, a protective component 3 installed on the outside of the battery body 1, and a safety valve 4 installed in the center of the top of the battery body 1.

[0025] See Figure 2 and Figure 3 Furthermore, the sealing assembly 2 includes a top cover 5, which is installed on the top of the battery body 1. The top cover 5 has cavities 6 on both sides inside. Two exhaust pipes 7 are fixedly installed through the top of the top cover 5. A sealing cover 8 is movably installed on the top of the exhaust pipe 7. An exhaust groove 9 is opened inside the exhaust pipe 7. A guide rod 10 is fixedly installed at the bottom of the sealing cover 8. A sealing plug 11 is fixedly installed at the bottom end of the guide rod 10. A spring 12 is sleeved on the outside of the guide rod 10. Several through holes 13 are opened through the top of the exhaust pipe 7.

[0026] The top cover 5 is fixedly installed on the top of the battery body 1 with adhesive. The top of the top cover 5 has a terminal for connecting to the battery body 1 near the rear end. The top cover 5 covers and seals the top of the battery body 1 and provides protection. The two terminals are used to connect the positive and negative terminals.

[0027] The guide rod 10 is located inside the exhaust pipe 7 and is slidably positioned up and down. The sealing cover 8 covers the top of the through hole 13. The guide rod 10 slides down under the action of the spring 12, so that the sealing cover 8 seals the top of the exhaust pipe 7.

[0028] The sealing plug 11 is located at the bottom of the exhaust pipe 7 and matches each other. The upper and lower ends of the spring 12 are in contact with the top of the exhaust groove 9 and the top of the sealing plug 11, respectively. When the internal air pressure of the top cover 5 is large, the guide rod 10 drives the sealing cover 8 and the sealing plug 11 to slide upward and discharge the gas.

[0029] Specifically, when some liquid is discharged, it is collected through the cavity 6. The gas inside the top cover 5 pushes open the sealing plug 11, causing the guide rod 10 and the sealing cover 8 to slide upward and open the exhaust pipe 7, thus venting the gas and preventing the liquid from being discharged along with it.

[0030] Example 2

[0031] See Figure 4 Furthermore, based on Embodiment 1, the protective component 3 includes a protective cover 14, which is installed on the bottom of the outer side of the battery body 1. A heat-conducting plate 15 is installed between the inner wall of the protective cover 14 and the battery body 1, and several heat dissipation grooves 16 are opened through the outer side of the protective cover 14.

[0032] The top of the protective cover 14 is open, and the protective cover 14 covers the front, back, sides and bottom of the battery body 1. The protective cover 14 is used to fix the heat conduction plate 15, and the heat dissipation groove 16 is used to dissipate heat from the heat conduction plate 15.

[0033] The heat-conducting plate 15 is glued and fixed to the inner wall of the battery body 1 and the protective cover 14. Several heat dissipation grooves 16 are arranged in a matrix. The heat-conducting plate 15 absorbs the heat inside the battery body 1 and enhances the external protection of the battery body 1.

[0034] Specifically, the heat-conducting plate 15 absorbs the heat of the battery body 1 and dissipates it through the heat dissipation groove 16, thereby improving the protection of the battery body 1.

[0035] In actual operation, the top cover 5 is fixedly installed on the top of the battery body 1 with adhesive, and the two terminals are connected to the positive and negative terminals respectively. The safety valve 4 is used to control the pressure inside the battery body 1.

[0036] When sealing and venting, the safety valve 4 vents the gas inside the battery body 1. When some liquid is discharged, the liquid flows into the two side cavities 6 and is collected through the cavities 6. At the same time, when the gas pressure inside the top cover 5 is high, the gas pushes open the sealing plug 11, causing the guide rod 10 and the sealing cover 8 to slide upward and open the exhaust pipe 7 to discharge the gas, thereby preventing the liquid from being discharged.

[0037] When providing protection, the heat-conducting plate 15 and the protective cover 14 are installed on the outside of the battery body 1. The heat-conducting plate 15 absorbs the heat of the battery body 1 and dissipates the heat through the heat dissipation groove 16. The heat-conducting plate 15 is fixed by the protective cover 14. The heat-conducting plate 15 further improves the protection of the battery body 1 and reduces external scratches and punctures.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
