Head-mounted display equipment host and head-mounted display equipment

Abstract

The invention provides head-mounted display equipment host and head-mounted display equipment . A host body of the head-mounted display equipment host comprises a shell, wherein the shell comprises a front shell, a rear shell and a mounting cavity, the front shell and the rear shell both protrude towards the rear side to be in an arc shape, the mounting cavity is an arc-shaped cavity, and a battery assembly and a mainboard assembly are fixedly arranged in the mounting cavity; and the battery assembly comprises a plurality of first square batteries and a battery pack FPC, the battery pack FPC is provided with a positive electrode pad group and a negative electrode pad group which are separated from each other, the positive electrode pad group comprises a plurality of first positive electrode bonding pads, the negative electrode pad group comprises a plurality of first negative electrode bonding pads, positive electrode connecting wires of the first square batteries are welded on the first positive electrode bonding pads, and negative electrode connecting wires are welded on the first negative electrode bonding pads. According to the head-mounted display equipment host, the separated layout of the bonding pads is realized, the welding of electrode connecting wires can be facilitated, the wiring of the battery connecting wires is ordered, the touch short circuit between different electrodes of the battery or the breakdown between the electrodes is avoided, and the use safety and reliability of the battery are ensured.

Description

technical field [0001] The invention relates to the technical field of smart wearable devices, in particular to a head-mounted display device host and a head-mounted display device. Background technique [0002] Head-mounted display devices, such as AR glasses or VR helmets, in order to balance the front and rear weights and improve wearing comfort, the device as a whole is usually split into two parts, the front part is used for display, and the rear part is used for computing. The host part, the display part and the host part are connected by straps; the host part integrates main power consumption devices such as batteries and circuit boards. [0003] In order to wear comfortably, the shape of the host part needs to be made as small as possible. At the same time, in order to match the shape of the head, the outline needs to have a certain arc in both the X direction and the Z direction, so its internal space is arc-shaped, while the circuit board, battery The main compone...

Problems solved by technology

[0003] In order to wear comfortably, the shape of the host part needs to be made as small as possible. At the same time, in order to match the shape of the head, the outline needs to have a certain arc in both the X direction and the Z direction, so its internal space is arc-shaped, while the circuit board, battery The main components are all regular cuboid shapes, which cannot fully fill the arc-shaped internal space of the main unit, resulting in waste of internal space, resulting in a small total capacity of the battery that can actually be accommodated, which cannot meet the requirements of long battery life

In order to improve battery life, some products use curved batteries. Although the internal space of the main unit can be effectively used, the cost of curved batteries is high and the reliability is low; some products use multiple square batteries, but in a limited irregular space, The positive and negative connecting wires of multiple prismatic batteries are likely to cause a short circuit or even a voltage breakdown when soldered on the pad or during use, which affects the safety of the product.
