Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a novel battery compartment structure and a smart door lock. Background Technology

[0002] With the rapid development of portable electronic devices, power tools, drones, home appliances, and electric vehicles, batteries, as their core power source, have been widely used. Among them, rechargeable batteries, such as lithium-ion batteries and nickel-metal hydride batteries, have become the preferred choice for the vast majority of modern electronic devices due to their high energy density and recyclability. These batteries are typically supplied in standardized cylindrical or prismatic shapes and are mounted and secured in specialized battery compartments.

[0003] In existing technologies, the structural design of most battery compartments follows the principles of simplicity and universality. A common structure includes a cylindrical compartment open at both ends, with positive and negative electrode contacts (usually spring-loaded pins or metal contacts) at both ends inside. Users simply push the battery axially into the compartment, ensuring physical contact between its two poles and the corresponding electrode contacts to complete the circuit connection. However, this seemingly convenient design has a long-standing, unresolved inherent flaw: the positive and negative terminals of the battery compartment are typically centrally or rotationally symmetrically distributed, meaning the battery can be inserted in either direction. If the user accidentally installs the battery in the wrong orientation, the positive and negative terminals will be opposite to the desired polarity of the electrical device's circuitry. This reverse connection can lead to a series of serious safety hazards and equipment risks, such as short circuits and equipment damage. Utility Model Content

[0004] Therefore, it is necessary to provide a new battery compartment structure and smart lock to address the potential serious safety hazards and equipment risks caused by reversed battery installation.

[0005] A novel battery compartment structure for loading a battery, the battery including a positive electrode surface and a negative electrode surface, the positive electrode surface including a positive electrode and an abutting portion, the positive electrode protruding from the center of the positive electrode surface, the abutting portion being arranged around the positive electrode, and the negative electrode surface having a negative electrode. The novel battery compartment structure includes multiple compartments, each compartment including a first contact end and a second contact end. The first contact end includes a first contact that engages with the positive electrode and an abutment block that engages with the abutment portion. The second contact end includes a second contact that engages with the negative electrode. The abutment block abuts against the abutment portion, and the distance between the abutment block and the second contact is less than the distance between the first contact and the second contact.

[0006] In use, the user installs the positive terminal of the battery on the first contact end and the negative terminal on the second contact end, electrically connecting the positive terminal to the first contact. The abutment block abuts against the abutment part, and the negative terminal is electrically connected to the second contact, allowing the battery to supply power normally. If the user accidentally installs the positive terminal on the second contact end and the negative terminal on the first contact end, the distance between the abutment block and the second contact is smaller than the distance between the first and second contacts, allowing the abutment block to contact the negative terminal while preventing the first contact from contacting the negative terminal. This physically eliminates the possibility of forming a closed circuit and generating a short-circuit current, making the new battery compartment structure safer and more reliable. When the battery is correctly installed, the abutment block and the abutment part effectively absorb vibrations and impacts generated during use, preventing the battery from shaking within the battery compartment and ensuring a continuous, stable, and reliable electrical connection between the first contact and the positive terminal of the battery. It can be seen that the new battery compartment structure, through a purely mechanical design, fundamentally eliminates the possibility of reverse battery installation. Moreover, the structure is simple, easy to realize through molds, and has low production costs, making it very suitable for large-scale industrial applications.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] This utility model discloses a novel battery compartment structure.

[0019] like Figures 1 to 4As shown, the novel battery compartment structure is used to load a battery 20. The battery 20 includes a positive electrode surface 21 and a negative electrode surface 22. The positive electrode surface 21 includes a positive electrode 211 and an abutment portion 212. The positive electrode 211 protrudes from the center of the positive electrode surface 21, and the abutment portion 212 is arranged around the positive electrode 211. The negative electrode surface 22 is provided with a negative electrode 221. The novel battery compartment structure includes multiple compartments 10. Each compartment 10 includes a first contact end 11 and a second contact end 12. The first contact end 11 includes a first contact 111 that engages with the positive electrode 211 and an abutment block 112 that engages with the abutment portion 212. The second contact end 12 includes a second contact 121 that engages with the negative electrode 221. The abutment block 112 abuts against the abutment portion 212. The distance between the abutment block 112 and the second contact 121 is smaller than the distance between the first contact 111 and the second contact 121.

[0020] In use, the user installs the positive electrode 21 of the battery 20 on the first contact end 11 and the negative electrode 22 on the second contact end 12, electrically connecting the positive electrode 211 to the first contact 111. The abutment block 112 abuts against the abutment part 212, and the negative electrode 221 is electrically connected to the second contact 121, allowing the battery 20 to supply power normally. If the user accidentally installs the positive electrode 21 of the battery 20 on the second contact end 12 and the negative electrode 22 on the first contact end 11, the distance between the abutment block 112 and the second contact 121 is smaller than the distance between the first contact 111 and the second contact 121, causing the abutment block 112 to contact the negative electrode 22. This avoids contact between the first contact 111 and the negative electrode 22, thus physically eliminating the possibility of forming a closed circuit and generating a short-circuit current. This makes the new battery compartment structure safer and more reliable. When the battery 20 is correctly installed, the abutment block 112 abuts against the abutment part 212, effectively absorbing the vibration and impact generated during equipment use, preventing the battery 20 from shaking inside the battery compartment, and ensuring a continuous, stable, and reliable electrical connection between the first contact 111 and the positive terminal 211 of the battery 20. It can be seen that this novel battery compartment structure, through a purely mechanical design, fundamentally eliminates the possibility of the battery 20 being installed backwards. Furthermore, its simple structure is easy to implement using molds, resulting in low production costs, making it highly suitable for large-scale industrial applications.

[0021] The first contact end 11 is marked with a positive polarity indicator, and the second contact end 12 is marked with a negative polarity indicator. By marking the first contact end 11 with a positive polarity indicator and the second contact end 12 with a negative polarity indicator, intuitive visual guidance is provided to the user, further reducing the probability of incorrect installation due to user negligence and improving the user experience and human-computer interaction friendliness of the product.

[0022] The abutment block 112 includes a first abutment block 1121 and a second abutment block 1122, with a first gap between them. The positive electrode 211 passes through the first gap and is electrically connected to the first contact 111. By setting the first abutment block 1121 and the second abutment block 1122 respectively, and setting a gap between them, the positive electrode surface 21 is subjected to balanced force, and the positive electrode 211 can be stably electrically connected to the first contact 111.

[0023] The first abutment block 1121 has a first protrusion of the mating abutment portion 212, and the second abutment block 1122 has a second protrusion of the mating abutment portion 212. By providing the first protrusion of the mating abutment portion 212 on the first abutment block 1121 and the second protrusion of the mating abutment portion 212 on the second abutment block 1122, slight sliding or rotation of the battery 20 on the abutment portion 212 can be prevented, further enhancing connection stability and vibration resistance.

[0024] Furthermore, both the first and second protrusions are made of rubber. Because they are made of rubber, they can absorb impacts and vibrations, thus protecting the battery 20 and the first contact 111. At the same time, the high coefficient of friction of rubber prevents the battery 20 from slipping, making it more secure. Since rubber is an excellent insulator, even if the battery 20 is installed backwards, it ensures that there will be no accidental electrical conduction between the contact block 112 and the circuit, improving safety.

[0025] The second contact 121 is a spring contact, and the second contact end 12 also includes a limiting block 122 that cooperates with the second contact 121. Since the second contact 121 is a spring contact, by setting the limiting block 122 that cooperates with the second contact 121, the second contact 121 can be prevented from being over-compressed and causing elastic deformation, thereby improving the service life of the battery compartment.

[0026] Furthermore, the limiting block 122 includes a first limiting block 1221 and a second limiting block 1222, with a second gap between the first limiting block 1221 and the second limiting block 1222. The second contact 121 passes through the second gap and is electrically connected to the negative electrode 221. By setting the first limiting block 1221 and the second limiting block 1222, and providing a second gap between them, the negative electrode surface 22 is subjected to balanced force, and the second contact 121 passes through the second gap to achieve a stable electrical connection with the negative electrode 221.

[0027] This utility model also discloses a smart door lock. The smart door lock includes the aforementioned novel battery compartment structure. Due to the adoption of this novel battery compartment structure, the possibility of incorrect battery installation is fundamentally eliminated, effectively improving security performance and user experience.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
