Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a battery holder and its lighting fixture. Background Technology

[0002] Existing lighting fixtures have battery holders that are not compatible with multiple types of batteries; the battery holders either only support dry cell batteries or only support lithium batteries.

[0003] However, both dry cell batteries and lithium batteries have their own performance advantages and disadvantages. Designing a battery holder that is compatible with multiple battery types, supporting both dry cell and lithium battery use, is a technical problem that designers need to solve.

[0004] Furthermore, in the design of the battery holder that is compatible with multiple battery types, the issue of mistaken identity must be considered. Only one type of battery can be installed on the battery holder: either a dry cell battery or a lithium battery. If a dry cell battery is installed on the battery holder, the lithium battery must be removed from the battery holder; conversely, if a lithium battery is installed on the battery holder, the dry cell battery must be removed from the battery holder. It is understandable that dry cell batteries and lithium batteries cannot be installed on the battery holder simultaneously, otherwise it will cause system instability. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery holder that is compatible with multiple types of batteries, and allows only one type of dry cell battery or lithium battery to be installed on the battery holder.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 and Figure 2 As shown, this utility model discloses a battery holder 10, which includes: a holder body 100, a first battery ejector plate 200, a second battery ejector plate 300, a lithium battery positive electrode 400, a lithium battery negative electrode 500, a dry cell battery positive electrode 600, and a dry cell battery negative electrode 700. In this embodiment, the holder body 100 is a plastic structure, which has advantages such as good insulation, light weight, and low production cost.

[0023] like Figure 3 As shown, the support body 100 has a lithium battery accommodating slot 110 and a dry cell battery accommodating slot 120. The lithium battery accommodating slot 110 and the dry cell battery accommodating slot 120 are interconnected and form a shared space. The lithium battery accommodating slot 110 occupies part of the space of the dry cell battery accommodating slot 120, and the dry cell battery accommodating slot 120 occupies part of the space of the lithium battery accommodating slot 110.

[0024] The lithium battery holder 110 and the dry cell battery holder 120 are interconnected and form a shared space. The lithium battery holder 110 occupies part of the space in the dry cell battery holder 120, and vice versa. Therefore, only one type of battery can be installed on the bracket body at a time. When the dry cell battery is installed on the bracket body, it occupies part of the space in the lithium battery holder 110, meaning the lithium battery cannot be fully installed there. Similarly, when the lithium battery is installed on the bracket body, it occupies part of the space in the dry cell battery holder 120, meaning the dry cell battery cannot be fully installed there. This is a good foolproof design, preventing incorrect identification and system confusion by allowing only one type of battery to be installed on the bracket body.

[0025] like Figure 2 As shown, the first battery ejector plate 200 and the second battery ejector plate 300 are respectively disposed at both ends of the bracket body 100, and the first battery ejector plate 200 and the second battery ejector plate 300 are connected by a wire 800.

[0026] like Figure 1 and Figure 2 As shown, the lithium battery positive electrode 400 and the lithium battery negative electrode 500 are respectively connected to the first battery ejector plate 200 and the second battery ejector plate 300, and the dry cell positive electrode 600 and the dry cell negative electrode 700 are respectively connected to the first battery ejector plate 200 and the second battery ejector plate 300.

[0027] like Figure 3As shown, in this embodiment, the dry cell battery accommodating slot 120 includes: an independent dry cell battery slot 121 and a shared dry cell battery slot 122; wherein, the lithium battery accommodating slot 110 and the shared dry cell battery slot 121 are interconnected and form a shared space.

[0028] Please refer to the following: Figure 4 , Figure 5 and Figure 6 Furthermore, the battery holder 10 also includes three dry cell batteries 20 connected in series. One dry cell battery 20 is placed in an independent dry cell battery slot 121, and the other two dry cell batteries 20 are placed in a shared dry cell battery slot 122. Adjacent dry cell batteries 20 are connected by a series spring 900 (e.g., Figure 2 (As shown) Connection. Preferably, the dry cell batteries are AA dry cell batteries. By connecting three dry cell batteries 20 in series, the voltage required by the lighting fixture is achieved.

[0029] Please refer to the following: Figure 7 , Figure 8 and Figure 9 Furthermore, the battery holder 10 also includes a lithium battery 30, which is placed in the lithium battery receiving slot 110. Preferably, the lithium battery is a 21700 rechargeable lithium battery.

[0030] like Figure 2 As shown, in this utility model, the first battery ejector plate 200 has: two symmetrically arranged lithium battery positive contacts 210, two symmetrically arranged dry cell battery positive contacts 220, and two symmetrically arranged battery negative contacts 230.

[0031] like Figure 2 As shown, similarly, the second battery ejector plate 300 has: two symmetrically arranged lithium battery positive contacts 310, two symmetrically arranged dry cell battery positive contacts 320, and two symmetrically arranged battery negative contacts 330.

[0032] Symmetrical positive and negative contacts are provided on the first battery ejector plate 200 and the second battery ejector plate 300. In this way, when the battery bracket 10 is installed on the lighting fixture, the installer does not need to identify or adjust the posture of the battery bracket 10. The battery bracket 10 can be inserted into the housing of the lighting fixture to achieve the correct electrical connection, achieving the effect of "blind installation" to turn on the power.

[0033] like Figure 10 As shown, this utility model also discloses a lighting fixture 40, which includes the battery bracket 10 mentioned above, and also includes a housing 41 and a lighting component 42 disposed on the housing 41. The battery bracket 10 is housed in the housing 41 and electrically connected to the lighting component 42.

[0034] 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.
